A Plan for Digital Cities

Southbank

The “Festival of Love” on London’s Southbank in 2014. Sometimes unattractive technologies – in this case concrete – can create great places.

As an IT Architect in the 1990s, I used Design Patterns as a tool to exchange knowledge with industry colleagues as we tried to solve what were then complex challenges – the execution of failure-proof transactions across distributed applications on the early World Wide Web, for example.

Much of the digital technology suffusing today’s world is engineered to those patterns – when we use a function of an app or website, we invoke a piece of software fitting the “Command” pattern. The Design Pattern was, of course, invented by Christopher Alexander, a town planner. The world of technology owes much of its design today to the tool he created.

Today, the influence of technology back into the professions of the built environment is increasing rapidly. We can use computer vision, the internet of things and machine learning to measure the physical world and the behaviour of people and organisations within it; to analyse them; and to design places and services for them to use.

But whilst “Smart Buildings” have been talked about and sometimes built since the 1980s, and “Smart Cities” since the late 1990s, they are largely one-off showcases and experiments rather than our mainstream approach to creating great places in a digital world.

Partly this is because the technology, built environment and investment professions lack a common, modern understanding of value creation. A leading economist recently described the mechanism by which urban economies grow due to the presence of public physical infrastructure that enables us to travel, meet and transact, generating incentives for further investment. That description completely overlooks the astonishing growth in physical transactions that are mediated online.

Copenhagen

This “interface design” in Frederiksberg, Copenhagen, prioritises pedestrian and bicycle traffic along a main road over cars joining from sideroads. Open Data and Open APIs are two equivalent technology policies that seek to promote individual adaptability of digital systems.

From dog-walking to household tool-sharing to transportation, thousands of services now make online introductions between people and companies who would never previously have connected. According to CrunchBase, Venture Capital investments in the technology start-up companies that enable those services is between $150 billion to $200 billion annually. They are changing the way that we work, meet and live.

As a consequence, communities, property companies and local authorities are arguably not setting the digital agenda for the built environment – individual citizens and tenants are selecting their own technology from the market, for their own reasons. The controversies created by “gig economy” employment and the sub-letting of accommodation through peer-to-peer services illustrate that the results are not always consistent with our aspirations.

If we want to create great places which benefit from flourishing digital innovation and enterprise, our first challenge is to better articulate the potential benefits of digital services. For example, students living in University accommodation with good internal and external 4G coverage – enabled by sufficient broadband capacity – will find the streaming video and social media services they use to socialise, access content, and perform research more reliable. They will provide better feedback on their student experience, helping the University to attract more students and to increase fee income.

We next need a common process for applying our expertise. So in “Digital Masterplanning”, we complement traditional masterplanning, planning and design processes by specifying digital infrastructures, policies and services for buildings and places.

For a property developer or owner, that might involve defining a common set of digital services across a portfolio, along with open standards for interoperability so that they are not overwhelmed by a multitude of different systems. A local authority digital masterplan might require new infrastructure and property developments to provide open data and public wi-fi, so that the public realm is both physically and digitally adaptable. A digital masterplan for a new town of 10,000 residents in Scandinavia included digitally-enabled de-centralised renewable energy and low carbon mobility schemes, playful and informative environments, distributed places of work and learning, and data privacy and security.

Finally, we need to measure the value of digital infrastructure and services, and convert that value – which is often personal, social, environmental or economic – into the creation of a financial return for investors.

Digbeth

Digbeth in Birmingham, UK, is an example of an urban place that has attracted a variety of successful creative digital businesses, and that – despite its heritage of industrial decay – flourishes as a place.

For example, for companies that operate sites undergoing re-development or construction, we have explored the value of “digital wayfinding” tools that adapt as physical space is altered on a daily basis. Successful digital wayfinding can reduce time that is literally “lost” and reduce stress and frustration, contributing to productivity both directly and indirectly. In neighbourhood-scale regenerations, we can mediate a balance between the interests of local authorities to secure investment in public digital infrastructure, and the level of competition from private property and infrastructure investors seeking a reasonable rate of return.

In his 1964 book, “Notes on the Synthesis of Form”, Alexander explained that new multidisciplinary approaches were necessary because “new materials are developed all the time, social patterns alter quickly, they also change faster than before”. The amount of digital information in the world overtook the amount of information stored in traditional forms in the early 2000s, and is now doubling every 3 years. The creation of new digital materials and social patterns is still speeding up, and challenges professionals of all disciplines working in the built environment to cooperate to turn them to our advantage.

(Or, why technology created the economy that helped Donald Trump and Brexit to win, and why we have to fix it.)

The world has not just been thrown into crisis because the UK voted in June to leave the European Union, and because the USA has just elected a President whose campaign rhetoric promised to tear up the rulebook of international behaviour (that’s putting it politely; many have accused him of much worse) – including pulling out of the global climate accord that many believe is the bare minimum to save us from a global catastrophe.

Those two choices (neither of which I support, as you might have guessed) were made by people who feel that a crisis has been building for years or even decades, and that the traditional leaders of our political, media and economic institutions have either been ignoring it or, worse, are refusing to address it due to vested interests in the status quo.

That crisis – which is one of worklessness, disenfranchisement and inequality for an increasingly significant proportion of the world’s population – is real; and is evident in figures everywhere:

… and so on.

Brexit and Donald Trump are the wrong solutions to the wrong problems

Of course, leaving the EU won’t solve this crisis for the UK.

Take the supposed need to limit immigration, for example, one of the main reasons people in the UK voted to leave the EU.

The truth is that the UK needs migrants. Firstly, with no immigration, the UK’s birth rate would be much lower than that needed to maintain our current level of population. That means less young people working and paying taxes and more older people relying on state pensions and services. We wouldn’t be able to afford the public services we rely on.

Secondly, the people most likely to start new businesses that grow rapidly and create new jobs aren’t rich people who are offered tax cuts, they’re immigrants and their children. And of course, what will any country in the world, let alone the EU, demand in return for an open trade deal with the UK? Freedom of immigration.

So Brexit won’t fix this crisis, and whilst Donald Trump is showing some signs of moderating the extreme statements he made in his election campaign (like both the “Leave” and “Remain” sides of the abysmal UK Referendum campaign, he knew he was using populist nonsense to win votes, but wasn’t at all bothered by the dishonesty of it), neither will he.

[Update 29/01/17: I take it back: President Trump isn’t moderating his behaviour at all. What a disgrace.]

Whatever his claims to the contrary, Donald Trump’s tax plan will benefit the richest the most. Like most Republican politicians, he promotes policies that are criticised as “trickle-down” economics, in which wealth for all comes from providing tax cuts to rich people and large corporations so they can invest to create jobs.

But this approach does not stand up to scrutiny: history shows that – particularly in times of economic change –  jobs and growth for all require leadership, action and investment from public institutions – in other words they depend on the sensible use of taxation to redistribute the benefits of growth.

Similarly, scrapping America’s role in the Trans-Pacific Partnership trade deal is unlikely to bring back manufacturing jobs to the US economy at anything like the scale that some of those who voted for Donald Trump hope, and that he’s given the impression it will.

In fact, manufacturing jobs are already rising in the US as the need for agility in production in response to local market conditions outweighs the narrowing difference in manufacturing cost as the salaries of China’s workers have grown along with its economy.

However, the real challenge is that the skills required to secure and perform those jobs have changed: factory workers need increasingly technical skills to manage the robotic machinery that now performs most of the work.

Likewise, jobs in the US coal industry won’t return by changing the way the US trades with foreign countries. The American coal mined in some areas of the country has become an uncompetitive fuel compared to the American shale gas that is made accessible in other areas by the new technology of “fracking”. (I’m not in favour of fracking; I’d prefer we concentrate our resources developing genuinely low-carbon, renewable energy sources. My point is that Donald Trump’s policies won’t address the job dislocation it has caused).

So, if the UK’s choice to leave the EU and the USA’s choice to elect Donald Trump represent the wrong solutions to the wrong problems, what are the underlying problems that are creating a crisis? And how do we fix them?

The crisis begins in places that don’t work

When veteran BBC journalist John Humphreys travelled the UK to meet communities which have experienced a high degree of immigration, he found that immigration itself isn’t a problem. Rather, the rise in population  caused by immigration becomes a problem when it’s not accompanied by investment in local infrastructure, services and business support. Immigrants are the same as people everywhere: they want to work; they start businesses (and in fact, they’re more likely to do that well than those of us who live and work in the country where we’re born); and they do all the other things that make communities thrive.

But the degree to which people – whether they’re immigrants or not – are successful doing so depends on the quality of their local environment, services and economy. And the reality is that there are stark, place-based differences in the opportunity people are given to live a good life.

In UK cities, life expectancy between the poorest and richest parts of the same city varies by up to 28 years. Areas of low life expectancy typically suffer from “multiple deprivation“: poor health, low levels of employment, low income, high dependency on benefits, poor education, poor access to services … and so on. These issues tend to affect the same areas for decade after decade, and they occur in part because of the effects of the physical urban infrastructure around them.

eu-uk-regional-funding

(The UK’s less wealthy regions benefit enormously from EU investment; whilst it’s richer regions, made wealthy by London’s economy, are net contributors. The EU acts to redistribute UK taxes to the regions that need them most, in a way that the national Government in Westminster does not)

The failure to invest in local services and infrastructure to accommodate influxes of migrants isn’t the EU’s fault; it is caused by the failure of the UK national government to devolve spending power to the local authorities that understand local needs – local authorities in the UK control only 17% of local spending, as opposed to 55% on average across OECD countries.

Ironically, one of the crucial things the EU does (or did) with the UK’s £350 million per week contribution to its budget, a large share of which is paid for by taxes from London’s dominant share of the UK economy, is to give it back to support local infrastructure and projects which create jobs and improve communities. If the Remain campaign had done a better job of explaining the extent of this support, rather than trumpeting overblown scare stories about the national, London-centric economy from which many people feel they don’t benefit anyway, some of the regions most dependent on EU investment might not have voted to Leave.

Technology is exacerbating inequality

We should certainly try to improve urban infrastructure and services; and the “Smart City” movement argues for using digital technology to do so.

But ultimately, infrastructure and services simply support activity that is generated by the economy and by social activity, and the fundamental shift taking place today is not a technological shift that makes existing business models, services or infrastructure more effective. It is the transformation of economic and social interactions by new “platform” business models that exploit online transaction networks that couldn’t exist at all without the technologies we’ve become familiar with over the last decade.

Well known examples include:

  • Apple iTunes, exchanging music between producers and consumers
  • YouTube, exchanging video content between producers and consumers
  • Facebook, an online environment for social activity that has also become a platform for content, games, news, business and community activity
  • AirBnB – an online marketplace for peer-to-peer arrangement of accomodation
  • Über – an online marketplace for peer-to-peer arrangement of transport

… and so on. MIT economist Marshall Van Alstyne’s work shows that platform businesses are increasingly the most valuable and fastest growing in the world, across many sectors.

The last two examples in that list – AirBnB and Über – are particularly good examples of online marketplaces that create transactions that take place face-to-face in the real world; these business models are not purely digital as YouTube, for example, arguably is.

But whilst these new, technology-enabled business models can be extraordinarily successful – Airbnb has been valued at $30 billion only 8 years after it was founded, and Über recently secured investments that, 7 years after it was founded, valued the company at over $60 billion – many economists and social scientists believe that the impact of these new technology-enabled business models is contributing to increasing inequality and social disruption.

As Andy McAfee and Erik Bryjolfsson have explained in theory, and as a recent JP Morgan survey has demonstrated in fact (see graph and text in box below), as traditional businesses that provide permanent employment are replaced by online marketplaces that enable the exchange of casual labour and self-employed work, the share of economic growth that is captured by the owners of capital platforms – the owners and shareholders in companies like Amazon, Facebook and Über – is rising, and the share of economic growth that is distributed to people who provide labour – people who are paid for the work they do; by far the majority of us – is falling.

The impact of technology on the financial services sector is having a similar effect. Technology enables the industry to profit from the construction of increasingly complex derivative products that speculate on sub-second fluctuations in the value of stocks and other tradeable commodities, rather than by making investments in business growth. The effect again is to concentrate the wealth the industry creates into profits for a small number of rich investors rather than distributing it in businesses that more widely provide jobs and pay salaries.

Finally, this is also ultimately the reason why the various shifting forces affecting employment in traditional manufacturing industries – off-shoring, automation, re-shoring etc. – have not resulted in a belief that manufacturing industries are providing widespread opportunities for high quality employment and careers to the people and communities who enjoyed them in the past. Even whilst manufacturing activity grows in many developed countries, jobs in those industries require increasingly technical skills, at the same time that, once again, the majority of the profits are captured by a minority of shareholders rather than distributed to the workforce.

(Analysis by JP Morgan of 260,000 current account customers earnings from 30 sharing economy websites over 3 years. Customers using websites to sell labour do not increase their income; earnings from sharing economy websites simply replace earnings from other sources. Customers using sharing economy websites to exploit the value of capital assets they own, however, are able to increase their income. This evidence supports just one of the mechanisms explored by Andy McAfee and Erik Brynjolfsson through which it appears that the digital economy is contributing to increasing income inequality)

That is why inequality is rising across the world; and that is the ultimate cause of the sense of unfairness that led to the choice of people in the UK to leave the EU, and people in the USA to elect Donald Trump as their President.

I do not blame the companies at the heart of these developments for causing inequality – I do not believe that is their aim, and many of their leaders believe passionately that they are a force for good.

But the evidence is clear that their cumulative impact is to create a world that is becoming damagingly unequal, and the reason is straightforward. Our market economies reward businesses that maximise profit and shareholder return; and there is simply no direct link from those basic corporate responsibilities to wider social, economic and environmental outcomes.

There are certainly indirect links – successful businesses need customers with money to spend, and there are more of those when more people have jobs that pay good wages, for example. But technology is increasingly enabling phenomenally successful new business models that depend much less on those indirect links to work.

We’re about to make things worse

Finally, as has been frequently highlighted in the media recently, new developments in technology are likely to further exacerbate the challenges of worklessness and inequality.

After a few decades in which scientific and technology progress in Artifical Intelligence (AI) made relatively little impact on the wider world, in the last few years the exponential growth of data and the computer processing power to manipulate it have led to some striking accomplishments by “machine learning”, a particular type of AI technology.

Whilst Machine Learning works in a very different way to our own intelligence, and whilst the Artificial Intelligence experts I’ve spoken to believe that any technological equivalent to human intelligence is between 20 and 100 years away (if it ever comes at all), one thing that is obvious is that Machine Learning technologies have already started to automate jobs that previously required human knowledge. Some studies predict that nearly half of all jobs – including those in highly-skilled, highly-paid occupations such as medicine, the law and journalism- could be replaced over the next few decades.

But in the latter half, only Preston continued to grow as it transitioned successfully to a service economy. If cities do not adapt to changes in the economy driven by technology, history shows that they fail. From “Cities Outlook 1901” by Centre for Cities)

Über is perhaps the clearest embodiment of these trends combined. Whilst several cities and countries have compelled the company to treat their drivers as employees and offer improved terms and conditions, their strategy is unapologetically to replace their drivers with autonomous vehicles anyway.

I’m personally convinced that what we’re experiencing through these changes – and what we’ve possibly been experiencing for 50 years or more – is properly understood to be an Information Revolution that will reshape our world every bit as significantly as the Industrial Revolution.

And history shows us we should take the economic and social consequences of that very seriously indeed.

In the last Century as automated equipment replaced factory workers, many cities in the UK such as Sunderland, Birmingham and Bradford, saw severe job losses, economic depression and social challenges as they failed to adapt from a manufacturing economy to new industries based on knowledge-working.

In this Century many knowledge-worker jobs will be automated too, and unless we knowingly and successfully manage this huge transition into an economy based on jobs we can’t yet predict, the social and economic consequences – the crisis that has already begun – will be just as bad, or perhaps even worse.

So if the problem is the lack of opportunity, what’s the answer?

If trickle-down economics doesn’t work, top-down public sector schemes of improvement won’t work either – they’ve been tried again and again without much improvement to those persistently, multiply-deprived areas:

“For three generations governments the world over have tried to order and control the evolution of cities through rigid, top-down action. They have failed. Masterplans lie unfulfilled, housing standards have declined, the environment is under threat and the urban poor have become poorer. Our cities are straining under the pressure of rapid population growth, rising inequality, inadequate infrastructure, and failing systems of urban planning, design and development.”

– from “The Radical Incrementalist” by Kelvin Campbell, summarised here.

One of the most forward-looking UK local authority Chief Executives said to me recently that the problem isn’t that a culture of dependency on benefits exists in deprived communities; it’s that a culture of doing things for and to people, rather than finding ways to support them succeeding for themselves, permeates local government.

This subset of findings from Sir Bob Kerslake’s report on Birmingham City Council reflects similar concerns:

  • “The council, members and officers, have too often failed to tackle difficult issues. They need to be more open about what the most important issues are and focus on addressing them;
  • Partnership working needs fixing. While there are some good partnerships, particularly operationally, many external partners feel the culture is dominant and over-controlling and that the council is complex, impenetrable and too narrowly focused on its own agenda;
  • The council needs to engage across the whole city, including the outer areas, and all the communities within it;
  • Regeneration must take place beyond the physical transformation of the city centre. There is a particularly urgent challenge in central and east Birmingham.”

One solution that’s being proposed to the challenges of inequality and the displacement of jobs by automation is the “Universal Basic Income” – an unconditional payment made by government to every citizen, regardless of income and employment status. The idea is that such a payment ensures a good enough standard of living for everyone, even if many people lose employment or see their salaries fall; or chose to work in less financially rewarding occupations that have strong social value – caring for others, for example. Several countries, including Finland, Canada and the Netherlands have already begun pilots of this idea.

I think it’s a terrible mistake for two reasons.

Firstly, the proposed level of income – about $1500 per month – isn’t at all sufficient to address the vast levels of inequality that our economy has created. Whilst it might allow a majority of people to live a basically comfortable life, why should we accept that a small elite should exist at such a phenomenally different level of technology-enabled wealth as to be reminiscent of a science fiction dystopia?

Andy McAfee and Erik Brynjofflsson best expressed the second problem with a Universal Basic Income by quoting Voltaire in “The Second Machine Age“:

“Work keeps at bay three great evils: boredom, vice, and need.”

A Universal Basic Income might address “need”, to a degree, but it will do nothing to address boredom and vice. Most people want to work because they want to be useful, they want their lives to make a difference and they want to feel fulfilled – this is the “self-actualisation” at the apex of Maslow’s Hierarchy of Needs. Surely enabling everyone to reach that condition should be our aspiration for society, not a subsidy that addresses only basic needs?

Our answer to these challenges should be an economy that properly rewards the application of effort, talent and courage to achieving the objectives that matter to us most; not one that rewards the amoral maximisation of profits for the owners of capital assets accompanied by a gesture of redistribution that’s just enough to prevent civil unrest.

(Maslow's

(Maslow’s “Hierarchy of Needs”)

Three questions that reveal the solution

There are three questions that I think define the way to answer these challenges in a way that neither the public, private nor third sectors have yet done.

The first is the question at the heart of the idea of a Smart City.

There are a million different definitions of a “Smart City”, but most of them are variations on the theme of “using digital technology to make cities better”. The most challenging part of that idea is not to do with how digital technology works, nor how it can be used in city systems; it is to do with how we pay for investments in technology to achieve outcomes that are social, economic and environmental – i.e. that don’t directly generate a financial return, which is usually why money is invested.

Of course, there are investment vehicles that translate achievement against social, economic or environmental objectives into a financial return – Social Impact Bonds and Climate Bonds, for example.

Using such vehicles to support the most interesting Smart City ideas can be challenging, however, due to the level of uncertainty in the outcomes that will be achieved. Many Smart City ideas provide people with information or services that allow them to make choices about the energy they use; how and when they travel; and the products and services they buy. The theory is that when given the option to improve their social, economic and environmental impact, people will chose to do so. But that’s only the theory; the extent to which people actually change their behaviour is notoriously unpredictable. That makes it very difficult to create an investment vehicle with a predictable level of return.

So the first key question that should be answered by any solution to the current crisis is:

  • QUESTION 1: How can we manage the risk of investing in technology to achieve uncertain social, economic or environmental aims such as improving educational attainment or social mobility in our most deprived areas?

The international Smart City community (of which I am a part) has so far utterly failed to answer that question. In the 20 years that the idea has been around, it simply hasn’t made a noticeable difference to economic opportunity, social mobility or resilience – if it had, I wouldn’t be writing this article about a crisis. Earlier this year, I described the examples of Smart City initiatives around the world that are finally starting to make an impact, and below I’ll describe some actions we can take to replicate them and drive them forward at scale.

The second question is inspired by the work of the architect and town planner Kelvin Campbell, whose “Smart Urbanism” is challenging the decades of orthodox thinking that has failed to improve those most deprived areas of our cities:

The solution lies in mobilising peoples’ latent creativity by harnessing the collective power of many small ideas and actions. This happens whenever people take control over the places they live in, adapting them to their needs and creating environments that are capable of adapting to future change. When many people do this, it adds up to a fundamental shift. This is what we call making Massive Small change.”

from “The Radical Incrementalist” by Kelvin Campbell, summarised here.

Kelvin’s concept of “Massive Small change” forms the second key question that defines the solution to our crisis:

  • QUESTION 2: What are the characteristics of urban environments and policy that give rise to massive amounts of small-scale innovation?

That’s one of the most thought-provoking and insightful questions I can think of. “Small-scale” innovation is what everybody does, every day, as we try to get by in life: fixing a leaky tap, helping our daughter with her maths homework, closing that next deal at work, losing another kilogram towards our weight target, becoming a trustee of a local charity … and so on.

For some people, what begin as small-scale innovations eventually amount to tremendously successful lives and careers. Mark Zuckerberg learned how to code, developed an online platform for friends to stay in touch with each other, and became the 6th richest man on the planet, worth approximately $40 billion. On the other hand, 15 million people around the world, including a vast number of children, show their resourcefulness by searching refuse dumps for re-usable objects.

Recent research on the platform economy by the not-for-profit PEW Research Centre confirms these vast gaps in opportunity; and most concerningly identifies clear biases based on race, class, wealth and gender.

The problem with small-scale innovation doesn’t lie in making it happen – it happens all the time. The problem lies in enabling it to have a bigger impact for those in the most challenging circumstances. Kelvin’s work has found ways to do that in the built environment; how do we translate those ideas into the digital economy?

The final question is more subtle:

  • QUESTION 3: How do we ensure that massive amounts of small-scale innovation create collective societal benefits, rather than lots of individual successes?

One way to explain what I mean by the difference between widespread individual success and societal success is in terms of resilience. Over the next 35 years, about 2 billion more people worldwide will acquire the level of wealth associated with the middle classes of developed economies. As a consequence, they are likely to dramatically increase their consumption of resources – eating more meat and less vegetables; buying cars; using more energy. Given that we are already consuming our planet’s resources at an unsustainable rate, such an increase in consumption could great an enormous global problem. So our concept of “success” should be collective as well as individual – it should result in us moderating our personal consumption in favour of a sustainable society.

One of the central tenets of economics for nearly 200 years, the “Tragedy of the Commons“, asserts that individual motives will always overwhelm societal motives and lead to the exhaustion of shared resources, unless those resoures are controlled by a system of private ownership or by government regulation – unless some people or organisations are able to own and control the use of resources by others. We’ll return to this subject shortly, and to its study in the field of Evolutionary Social Biology.

Calling out the failure of the free market: a Three Step Manifesto for Smart Community Economies

If we could answer those three questions, we’d have defined a digital economy in which individual citizens, businesses and communities everywhere would have the skills, opportunities and resources to create their own success on terms that matter to them; and in a way that was beneficial to us all.

That’s the only answer to our current crisis that makes sense to me. It’s not an answer that either Brexit or Donald Trump will help us to find.

So how do we find it?

(The White Horse Tavern in Greenwich Village, New York, one of the city’s oldest taverns. The rich urban life of the Village was described by one of the Taverns’ many famous patrons, the urbanist Jane Jacobs. Photo by Steve Minor).

I think the answers are at our fingertips. In one sense, they’re no more than “nudges” that influence what’s happening already; and they’re supported by robust research in technology, economics, social science, biology and urban design. They lay out a three step manifesto for successful community economies, enabled by technology and rooted in place.

But in another sense, this is a call for fundamental change. These “nudges” will only work if they are enacted as policies, regulations and laws by national and local governments. “Regulation” is a dirty word to the proponents of free markets; but free markets are failing us, and it’s time we admitted that, and shaped them to our needs.

A global-local economy

Globalisation is inevitable – and in many ways beneficial; but ironically the same technologies that enable it can also enable localism, and the two trends do not need to be mutually exclusive.

Many urban designers and environmental experts believe that the best path to a healthy, successful, sustainable and equitable future economy and society lies in a combination of medium density cities with a significant proportion of economic activity (from food to manufacturing to energy to re-use and recycling) based on local transactions supported by walking and cycling.

The same “platform” business models employed by Über, Airbnb and so on could in theory provide the new transaction infrastructure to stimulate and enable such economies. In fact, I believe that they are unique in their ability to do so. Examples already exist – “Borroclub“, for instance, whose platform business connects people who need tools to do jobs with near neighbours who own tools but aren’t using them at the time. A community that adopts Borroclub spends less money on tools; exchanges the money it does spend locally rather than paying it to importers; accomplishes more work using fewer resources; and undertakes fewer car journeys to out-of-town DIY stores.

This can only be accomplished using social digital technology that allows us to easily and cheaply share information with hundreds or thousands of neighbours about what we have and what we need. It could never have happened using telephones or the postal system – the communication technologies of the pre-internet age.

This could be a tremendously powerful way to address the crisis we are facing. Businesses using this model could create jobs, reinforce local social value, reduce the transport and environmental impact of economic transactions and promote the sustainable use of resources; all whilst tapping into the private sector investment that supports growing businesses.

But private sector businesses will only drive social outcomes at scale if we shape the markets they operate in to make that the most profitable business agenda to pursue. The fact that we haven’t shaped the market yet is why platform businesses are currently driving inequality.

There are three measures we could take to shape the market; and the best news is that the first one is already being taken.

1. Legislate to encourage and support social innovation with Open Data and Open Technology

The Director of one of the UK’s first incubators for technology start-up businesses recently told me that “20 years ago, the only way we could help someone to start a business was to help them write a better business plan in order to have a better chance of getting a bank loan. Today there are any number of ways to start a business, and lots of them don’t need you to have much money.”

Technologies such as smartphones, social media, cloud computing and open source software have made it possible to launch global businesses and initiatives almost for free, in return for little more than an investment of time and a willingness to learn new skills. Small-scale innovation has never before had access to such free and powerful tools.

These are all examples of what was originally described as “Intermediate Technology” by the economist Ernst Friedrich “Fritz” Schumacher in his influential work, “Small is Beautiful: Economics as if People Mattered“, and is now known as Appropriate Technology.

Schumacher’s views on technology were informed by his belief that our approach to economics should be transformed “as if people mattered”. He asked:

“What happens if we create economics not on the basis of maximising the production of goods and the ability to acquire and consume them – which ends up valuing automation and profit – but on the Buddhist definition of the purpose of work: “to give a man a chance to utilise and develop his faculties; to enable him to overcome his ego-centredness by joining with other people in a common task; and to bring forth the goods and services needed for a becoming existence.”

Schumacher pointed out that the most advanced technologies, to which we often look to create value and growth, are in fact only effective in the hands of those with the resources and skills required to use them – i.e. those who are already wealthy. Further, by emphasising efficiency, output and profit those technologies tend to further concentrate economic value in the hands of the wealthy – often specifically by reducing the employment of people with less advanced skills and roles.

His writing seems prescient now.

A perfect current example is the UK Government’s strategy to drive economic growth by making the UK an international leader in autonomous vehicles, to counter the negative economic impacts of leaving the European Union. That strategy is based on further increasing the number of highly skilled technology and engineering jobs at companies and research insitutions already involved in the sector; and on the UK’s relative lack of regulations preventing the adoption of such technology on the country’s roads.

The strategy will benefit those people with the technological and engineering skills needed to create improvements in autonomous vehicle technology. But what will happen to the far greater number of people who earn their living simply by driving vehicles? They will first see their income fall, and second see their jobs disappear, as technology firstly replaces their permanent jobs with casual labour through platforms such as Über, and secondly completely removes their jobs from the economy by replacing them with self-driving technology. The UK economy might grow in the process; but vast numbers of ordinary people will see their jobs and incomes disappear or decline.

From the broad perspective of the UK workforce, that strategy would be great if we were making a massive investment in education to enable more people to earn a living as highly paid engineers rather than an average or low-paid living as drivers. But of course we’re not doing that at all; at best our educational spend per student is stagnant, and at worst it’s declining as class-sizes grow and we reduce the number of teaching assistants we employ.

In contrast, Schumacher felt that the most genuine “development ” of our society would occur when the most possible people were employed in a way that gave them the practical ability to earn a living; and that also offered a level of human reward – much as Maslow’s “Hierarchy of Needs” first identifies our most basic requirements for food, water, shelter and security; but next relates the importance of family, friends and “self-actualisation” (which can crudely be described as the process of achieving things that we care about).

This led him to ask:

“What is that we really require from the scientists and technologists? I should answer:

We need methods and equipment which are:

    • Cheap enough so that they are accessible to virtually everyone;
    • Suitable for small-scale application; and
    • Compatible with man’s need for creativity”

These are precisely the characteristics of the Cloud Computing, social media, Open Source and smartphone technologies that are now so widely available, and so astonishingly powerful. What we need to do next is to provide more support to help people everywhere put them to use for their own purposes.

Firstly, Open data, open algorithms and open APIs should be mandatory for any publicly funded service or infrastructure. They should be included in the procurement criteria for services and goods procured on behalf of the public sector. Our public infrastructure should be digitally open, accessible and accountable.

Secondly, some of the proceeds from corporate taxation – whether at national level or from local business rates – should be used to provide regional investment funds to support local businesses and social enterprises that contribute to local social, economic and environmental objectives; and to support the regional social innovation communities such as the network of Impact Hubs that help such initiatives start, succeed and grow.

But perhaps most importantly, those proceeds should also be used to fund improvements to state education everywhere. People can only use tools if they are given the opportunity to acquire skills; and as tools and technologies change, we need the opportunity to learn new skills. If our jobs – or more broadly our roles in society – are not ultimately to be replaced by machines, we need to develop the creativity to use those tools to create the human value that technology will never understand.

It is surely insane that we are pouring billions of pounds and dollars into the development of technologies that mean we need to develop new skills in order to remain employable, and that those investments are making our economy richer and richer; but that at the same time we are making a smaller and smaller proportion of that wealth available to educate our children.

Just as some of the profits of the Industrial Revolution were spent on infrastructure with a social purpose, so should some of the profits of the Information Revolution be.

2. Legislate to encourage and support business models with a positive social outcome

(Hancock Bank’s vault, damaged by Hurricane Katrina. Photo by Social Stratification)

The social quality of the behaviour of private sector businesses varies enormously.

The story of Hancock Bank’s actions to assist the citizens of New Orleans to recover from hurricane Katrina in 2005 – by lending cash to anyone who needed it and was prepared to sign an IoU – is told in this video, and is an extraordinary example of responsible business behaviour. In an unprecedented situation, the Bank’s leaders based their decisions on the company’s purpose, expressed in its charter, to support the communities of the city. This is in contrast to the behaviour of Bob Diamond, who resigned as CEO of Barclays Bank following the LIBOR rate-manipulation scandal, and who under questioning by parliamentary committee could not remember what the Bank’s founding principles, written by community-minded Quakers, stated.

Barclays’ employees’ behaviour under Bob Diamond was driven purely by the motivation to earn bigger bonuses by achieving the Bank’s primary objective, to increase shareholder value.

But the overriding focus on shareholders as the primary stakeholder in private sector business is relatively new. Historically, customers and employees have been treated as equally important. Some leading economists now believe we should return to such balanced models.

There are already models of business – such as “social enterprise” – which promote more balanced corporate governance, and that even offer accreditation schemes. We could incentivise such models to be more successful in our economy by creating a preferential market for them – lower rates of taxation; preferential scoring in public sector procurements; and so on.

An alternative is to use technology to enable entirely new, entirely open systems. “Blockchains” are the technology that enable the digital currency “Bitcoin“. The Bitcoin Blockchain is a single, distributed ledger that records every Bitcoin transaction so that anyone in the world can see it. So unlike the traditional system of money in which we depend on physical tokens, banks and payment services to define the ownership of money and to govern transactions, Bitcoin transactions work because everybody can see who owns which Bitcoins and when they’re being exchanged.

This principle of a “distributed, open ledger” – implemented by a blockchain – is thought by many technology industry observers to be the most important, powerfully disruptive invention since the internet. The Ethereum “smart contracts” platfom adds behaviour to the blockchain – open algorithms that cannot be tampered with and that dictate how transactions take place and what happens as a consequence of them. It is leading to some strikingly different new business models, including the “Distributed Autonomous Organisation” (or “DAO” for short), a multi-$million investment fund that is entirely, democratically run by smart contracts on behalf of its investors.

By promoting distributed, non-repudiatable transparency in this way, blockchain technologies offer unprecedented opportunities to ensure that all of the participants in an economic system have the opportunity to influence the distribution of the benefits of the system in a fair way. This idea is already at the heart of an array of initiatives to ensure that some of the least wealthy people in the world benefit more fairly from the information economy.

Finally, research in economics and in evolutionary social biology is yielding prescriptive insights into how we can design business models that are as wildly successful as those of Über and Airbnb, but with models of corporate governance that ensure that the wealth they create is more broadly and fairly distributed.

In conversation with a researcher at Imperial College London a few years ago, I said that I thought we needed to find criteria to distinguish “platform” businesses like Casserole Club that create social value from those like Über that concentrate the vast majority of the wealth they create in the hands of the platform owners. (Casserole Club uses social media to match people who are unable to provide meals for themselves with neighbours who are happy to cook and share an extra portion of their meal).

The researcher told me I should consult Elinor Ostrom’s work in Economics. Ostrom, who won the Nobel prize in 2009, spent her life working with communities around the world who successfully manage shared resources (land, forests, fresh water, fisheries etc.) sustainably, and writing down the common features of their organisational models. Her Nobel prize was awarded for using this evidence to disprove the “tragedy of the commons” doctrine which economists previously believed proved that sustainable commons management was impossible.

(Elinor Ostrom working with irrigation management in Nepal)

(Elinor Ostrom working with irrigation management in Nepal)

Most of Ostrom’s principles for organisational design and behaviour are strikingly similar to the models used by platform businesses such as Über and Airbnb. But the principles she discovered that are the most interesting are the ones that Über and Airbnb don’t follow – the price of exchange being agreed by all of the participants in a transaction, for example, rather than it being set by the platform owner. Ostrom’s work has been continued by David Sloan Wilson who has demonstrated that the principles she discovered follow from evolutionary social biology – the science that studies the evolution of human social behaviour.

Elinor Ostrom’s design principles for commons organisations offer us not only a toolkit for the design of successful, socially responsible platform businesses; they offer us a toolkit for their regulation, too, by specifying the characteristics of businesses that we should preferentially reward through market regulation and tax policy.

3. Legislate for individual ownership of personal data, and a right to share in the profits it creates. 

Platform business models may depend less and less on our labour – or at least, may have found ways to pay less for it as a proportion of their profits; but they depend absolutely on our data.

Of course, we – usually – get some value in return for our data – useful search results, guidance to the quickest route to our journey, recommendations of new songs, films or books we might like.

But is massive inequality really a price worth paying for convenience?

The ownership of private property and intellectual property underpin the capitalist economy, which until recently was primarily based on the value of physical assets and closed knowledge, made difficult to replicate through being stored primarily in physical, analogue media (including our brains).

Our economy is now being utterly transformed by easy to replicate, easy to transfer digital data – from news to music to video entertainment to financial services, business models that had operated for decades have been swept away and replaced by models that are constantly adapting, driven by advances in technology.

But data legislation has not kept pace. Despite several revisions of data protection and privacy legislation, the ownership of digital data is far from clearly defined in law, and in general its exchange is subject to individual agreements between parties.

It is time to legislate more strongly that the value of the data we create by our actions, our movement and our communication belongs to us as individuals, and that in turn we receive a greater share of the profits that are made from its use.

That is the more likely mechanism to result in the fair distribution of value in the economy as the value of labour falls than a Universal Basic Income that rewards nothing.

One last plea to our political leaders to admit that we face a crisis

Whilst the UK and the USA argue – and even riot – about the outcomes of the European Union referendum and the US Presidential election, the issues of inequality, loss of jobs and disenfranchisement from the political system are finally coming to light in the media.

But it’s a disgrace that they barely featured at all in either of those campaigns.

Emotionally right now I want to castigate our politicians for getting us into this mess through all sorts of venality, complacency, hubris and untruthfulness. But two things I know they are not – including Donald Trump – are stupid or ignorant. They surely must be aware of these issues – why will they not recognise and address them?

Robert Wright’s mathematical analysis of the evolution of human society, NonZero, describes the emergence of our current model of nation states through the European Middle Ages as a tension between the ruling and working classes. The working classes pay a tax to the ruling classes, who they accept will live a wealthier life, in return for a safe and peaceful environment in which to live. Whenever the price paid for safety and peace grew unreasonably high, the working classes revolted and overthrew the ruling classes, resulting eventually in a new, better-balanced model.

Is it scaremongering to suggest we are close to a similar era of instability?

(Anti-Donald Trump protesters in San Jose, California in June. Trump supporters leaving a nearby campaign rally were attacked)

(Anti-Donald Trump protesters in San Jose, California in June. Trump supporters leaving a nearby campaign rally were attacked)

I don’t think so. At the same time that the Industrial Revolution created widespread economic growth and improvements in prosperity, it similarly exacerbated inequality between the general population and the property- and business-owning elite. Just as I have argued in this article, that inequality was corrected not by “big government” and grand top-down redistributive schemes, but by measures that shaped markets and investments in education and enablement for the wider population.

We have not yet taken those corrective actions for the Information Revolution – nor even realised and acknowledged that we need to take them. Inequality is rising as a consequence, and it is widely appreciated that inequality creates social unrest.

Brexit and the election of Donald Trump following a campaign of such obvious lies, misogyny and – at best – narrow-minded nationalism are unprecedented in modern times. They have already resulted in social unrest in the form of riots and increased incidents of racism – as has the rise in the price of staple food caused by severe climate events as a vast number of people around the world struggle to feed themselves when hurricanes and droughts affect the production of basic crops. It’s no surprise that the World Economic Forum’s 2016 Global Risks Report identifies “unemployment and underemployment” and “profound social instability” as amongst the top 10 most likely and impactful global risks facing the world.

Brexit and Donald Trump are not crises in themselves; but they are symptoms of a real crisis that we face now; and until we – and our political leaders – face up to that and start dealing with it properly, we are putting ourselves, our future and our childrens’ future at unimaginable risk.

Thankyou to the following, whose opinions and expertise, expressed in articles and conversations, helped me to write this post:

Let’s not get carried away by self-driving cars and the sharing economy: they won’t make Smart Cities better places to live, work and play

(Cities either balance or create tension between human interaction and transport; how will self-driving cars change that equation?)

(Cities either balance or create tension between human interaction and transport; how will self-driving cars change that equation? With thanks and apologies to Tim Stonor for images and inspiration)

Will we remember to design cities for people and life, enriched by interactions and supported by transport? Or will we put the driverless car and the app that hires it before the passenger?

I’m worried that the current level of interest in self-driving cars as a Smart City initiative is a distraction from the transport and technology issues that really matter in cities.

It’s a great example of a technology that is attracting significant public, private and academic investment because many people will pay for the resulting product in return for the undoubted benefits to their personal safety and convenience.

But will cities full of cars driving themselves be better places to live, work and play than cities full of cars driven by people?

Cities create value when people in them transact with each other: that often requires meeting in person and/or exchanging goods – both of which require transport. From the medieval era to the modern age cities have in part been defined by the tension between our desire to interact and the negative effects created by the size, noise, pollution and danger of the transport that we use to do so – whether that transport is horses and wagons or cars and vans.

A number of town planners and urban designers argue that we’ve got that balance wrong over the past half century with the result that many urban environments are dominated by road traffic and infrastructure to the extent that they inhibit the human interactions that are at the heart of the social and economic life of cities.

What will be the effect of autonomous vehicles on that inherent tension – will they help us to achieve a better balance, or make it harder to do so?

(Traffic clogging the streets of Rome. Photo by AntyDiluvian)

Autonomous vehicles are driven in a different way than the cars that we drive today, and that creates certain advantages: freeing people from the task of driving in order to work or relax; and allowing a higher volume of traffic to flow in safety than currently possible, particularly on national highway networks. And they will almost certainly very soon become better at avoiding accidents with people, vehicles and their surroundings than human drivers.

But they are no smaller than traditional vehicles, so they will take up just as much space. And they will only produce less noise and pollution if they are electric vehicles (which in turn merely create pollution elsewhere in the power system) or are powered by hydrogen – a technology that is still a long way from large-scale adoption.

And whilst computer-driven cars may be safer than cars driven by people, they will not make pedestrians and cyclists feel any safer: people are more likely to feel safe in proximity with slow moving cars with whose drivers they can make eye contact, not automated vehicles travelling at speed. The extent to which we feel safe (which we are aware of) is often a more important influence on our social and economic activity than the extent to which we are actually safe (which we may well not be accurately aware of).

The tension between the creation of social and economic value in cities through interactions between people, and the transport required to support those interactions, is also at the heart of the world’s sustainability challenge. At the “Urban Age: Governing Urban Futures” conference in New Delhi,  November 2014, Ricky Burdett, Director of the London School of Economics’ Cities Program, described the graph below that shows the relationship between social and economic development, as measured by the UN Human Welfare Index, plotted left-to-right; and ecological footprint per person, which is shown vertically, and which by and large grows significantly as social and economic progress is made.  (You can watch Burdett’s presentation, along with those by other speakers at the conference, here).

(The relationship between social and economic development, as measured by the UN Human Welfare Index, plotted left-to-right and ecological footprint per person, which is shown vertically)

The dotted line at the bottom of the graph shows when the ecological footprint of each person passes beyond that which our world can support for the entire population. Residents of cities in the US are using five times this limit already, and countries such as China and Brazil, whose cities are growing at a phenomenal rate, are just starting to breach that line of sustainability.

Tackling this challenge does not necessarily involve making economic, social or personal sacrifices, though it certainly involves making changes. In recent decades, a number of politicians such as Enrique Penalosa, ex-Mayor of Bogota, international influencers such as  Joan Clos, Exective Director of UN-Habitat  (as reported informally by Tim Stonor from Dr. Clos’s remarks at the “Urban Planning for City Leaders” conference at the Crystal, London in 2012), and town planners such as Jeff Speck and Charles Montgomery have explored the social and economic benefits of cities that combine low-carbon lifestyles and economic growth by promoting medium-density, mixed-use urban centres that stimulate economies with a high proportion of local transactions within a walkable and cyclable distance.

Of course no single idea is appropriate to every situation, but overall I’m personally convinced that this is the only sensible general conception of cities for the future that will lead to a happy, healthy, fair and sustainable world.

There are many ways that technology can contribute to the development of this sort of urban economy, to complement the work of urban designers and town planners in the physical environment. For example, a combination of car clubs, bicycle hire schemes and multi-modal transport information services is already contributing to a changing culture in younger generations of urban citizens who are less interested in owning cars than previous generations.

(Top: Frederiksberg, Copenhagen, where cyclists and pedestrians on one of the districts main thoroughfares are given priority over cars waiting to turn onto the road. Bottom: Buford Highway, Atlanta, a 2 kilometre stretch of 7-line highway passing through a residential and retail area with no pavements or pedestrian crossings)

And this is a good example that it is not set in stone that cities must inevitably grow towards the high ecological footprints of US cities as their economies develop.

The physicist Geoffrey West’s work is often cited as proof that cities will grow larger, and that their economies will speed up as they do so, increasing their demand for resources and production of waste and pollution. But West’s work is “empirical”, not “deterministic”: it is simply based on measurements and observations of how cities behave today; it is not a prediction for how cities will behave in the future.

It is up to us to discover new services and infrastructures to support urban populations and their desire for ever more intense interactions in a less profligate way. Already today, cities diverge from West’s predictions according to the degree to which they have done so. The worst examples of American sprawl such as Houston, Texas have enormous ecological footprints compared to the standard of living and level of economy activity they support; more forward-thinking cities such as Portland, Vancouver, Copenhagen and Freiberg are far more efficient (and Charles Montgomery has argued that they are home to happier, healthier citizens as a consequence).

However, the role that digital technologies will play in shaping the economic and social transactions of future cities and that ecological footprint is far from certain.

On the one hand modern, technologies make it easier for us to communicate and share information wherever we are without needing to travel; but on the other hand those interactions create new opportunities to meet in person and to exchange goods and services; and so they create new requirements for transport. As technologies such as 3D printingopen-source manufacturing and small-scale energy generation make it possible to carry out traditionally industrial activities at much smaller scales, an increasing number of existing bulk movement patterns are being replaced by thousands of smaller, peer-to-peer interactions created by transactions in online marketplaces. We can already see the effects of this trend in the vast growth of traffic delivering goods that are purchased or exchanged online.

I first wrote about this “sharing economy“, defined by Wikipedia as “economic and social systems that enable shared access to goods, services, data and talent”, two years ago. It has the potential to promote a sustainable economy through matching supply and demand in ways that weren’t previously possible. For example, e-Bay CEO John Donahoe has described the environmental benefits created by the online second-hand marketplace extending the life of over $100 billion of goods since it began, representing a significant reduction in the impact of manufacturing and disposing of goods. But on the other hand those benefits are offset by the carbon footprint of the need to transport goods between the buyers and sellers who use them; and by the social and economic impact of that traffic on city communities.

There are many sharing economy business models that promote sustainable, walkable, locally-reinforcing city economies: Casserole Club, who use social media to introduce people who can’t cook for themselves to people who are prepared to volunteer to cook for others; the West Midlands Collaborative Commerce Marketplace, which uses analytics technology to help it’s 10,000 member businesses work together in local partnerships to win more than £4billion in new contracts each year, and Freecyle and other free recycling networks which tend to promote relatively local re-use of goods and services because the attraction of free, used goods diminishes with the increasing expense of the travel required to collect them.

But it takes real skill and good ideas to create and operate these business models successfully; and those abilities are just those that the MIT economists Andy McAfee, Erik Brynjolfsson and Michael Spence have pointed out can command exceptional financial rewards in a capitalist economy. What is there to incent the people who posess those skills to use them to design business models that achieve balanced financial, social and environmental outcomes, as opposed to simply maximising profit and personal return?

The vast majority of systematic incentives act to encourage such people to design businesses that maximise profit. That is why many social enterprises are small-scale, and why many successful “sharing economy” businesses such as Airbnb and Uber have very little to do with sharing value and resources, but are better understood as a new type of profit-seeking transaction broker. It is only personal, ethical attitudes to society that persuade any of us to turn our efforts and talents to more balanced models.

This is a good example of a big choice that we are taking in millions of small decisions: the personal choices of entrepreneurs, social innovators and business leaders in the businesses they start, design and operate; and our personal choices as consumers, employees and citizens in the products we buy, the businesses we work for and the politicians we vote for.

For individuals, those choices are influenced by the degree to which we understand that our own long term interests, the long term interests of the businesses we run or work for, and the long term interests of society are ultimately the same – we are all people living on a single planet together – and that that long-term alignment is more important than the absolute maximisation of short-term financial gain.

But as a whole, the markets that invest in businesses and enable them to operate and grow are driven by relatively short-term financial performance unless they are influenced by external forces.

In this context, self-driving cars – like any other technology – are strictly neutral and amoral. They are a technology that does have benefits, but those benefits are relatively weakly linked to the outcomes that most cities have set out as their objectives. If we want autonomous vehicles, “sharing economy” business models or the Internet of Things to deliver vibrant, fair, healthy and happy cities then more of our attention should be on the policy initiatives, planning and procurement frameworks, business licensing and taxation regimes that could shape the market to achieve those outcomes. The Centre for Data Innovation, British Standards Institute, and Future Cities Catapult have all published work on this subject and are carrying out  initiatives to extend it.

The London Legacy Development’s intention, in support of the Smart London Plan, is “for the Park to become one of the world’s leading digital environments, providing a unique opportunity to showcase how digital technology enhances urban living. The aim is to use the Park as a testing ground for the use of new digital technology in transport systems and energy services.”)

Cities create the most value in the most sustainable way when they encourage transactions between people that can take place over a walkable or cyclable distance. New technologies and new technology-enabled business models have great potential to encourage both of those outcomes, but only if we use the tools available to us to shape the market to make them financially advantageous to private sector enterprise.  We should be paying more attention to those tools, and less attention to technology.

11 reasons computers can’t understand or solve our problems without human judgement

(Photo by Matt Gidley)

Why data is uncertain, cities are not programmable, and the world is not “algorithmic”.

Many people are not convinced that the Smart Cities movement will result in the use of technology to make places, communities and businesses in cities better. Outside their consumer enjoyment of smartphones, social media and online entertainment – to the degree that they have access to them – they don’t believe that technology or the companies that sell it will improve their lives.

The technology industry itself contributes significantly to this lack of trust. Too often we overstate the benefits of technology, or play down its limitations and the challenges involved in using it well.

Most recently, the idea that traditional processes of government should be replaced by “algorithmic regulation” – the comparison of the outcomes of public systems to desired objectives through the measurement of data, and the automatic adjustment of those systems by algorithms in order to achieve them – has been proposed by Tim O’Reilly and other prominent technologists.

These approaches work in many mechanical and engineering systems – the autopilots that fly planes or the anti-lock braking systems that we rely on to stop our cars. But should we extend them into human realms – how we educate our children or how we rehabilitate convicted criminals?

It’s clearly important to ask whether it would be desirable for our society to adopt such approaches. That is a complex debate, but my personal view is that in most cases the incredible technologies available to us today – and which I write about frequently on this blog – should not be used to take automatic decisions about such issues. They are usually more valuable when they are used to improve the information and insight available to human decision-makers – whether they are politicians, public workers or individual citizens – who are then in a better position to exercise good judgement.

More fundamentally, though, I want to challenge whether “algorithmic regulation” or any other highly deterministic approach to human issues is even possible. Quite simply, it is not.

It is true that our ability to collect, analyse and interpret data about the world has advanced to an astonishing degree in recent years. However, that ability is far from perfect, and strongly established scientific and philosophical principles tell us that it is impossible to definitively measure human outcomes from underlying data in physical or computing systems; and that it is impossible to create algorithmic rules that exactly predict them.

Sometimes automated systems succeed despite these limitations – anti-lock braking technology has become nearly ubiquitous because it is more effective than most human drivers at slowing down cars in a controlled way. But in other cases they create such great uncertainties that we must build in safeguards to account for the very real possibility that insights drawn from data are wrong. I do this every time I leave my home with a small umbrella packed in my bag despite the fact that weather forecasts created using enormous amounts of computing power predict a sunny day.

(No matter how sophisticated computer models of cities become, there are fundamental reasons why they will always be simplifications of reality. It is only by understanding those constraints that we can understand which insights from computer models are valuable, and which may be misleading. Image of Sim City by haljackey)

We can only understand where an “algorithmic” approach can be trusted; where it needs safeguards; and where it is wholly inadequate by understanding these limitations. Some of them are practical, and limited only by the sensitivity of today’s sensors and the power of today’s computers. But others are fundamental laws of physics and limitations of logical systems.

When technology companies assert that Smart Cities can create “autonomous, intelligently functioning IT systems that will have perfect knowledge of users’ habits” (as London School of Economics Professor Adam Greenfield rightly criticised in his book “Against the Smart City”), they are ignoring these challenges.

A blog published by the highly influential magazine Wired recently made similar overstatements: “The Universe is Programmable” argues that we should extend the concept of an “Application Programming Interface (API)” – a facility usually offered by technology systems to allow external computer programmes to control or interact with them – to every aspect of the world, including our own biology.

To compare complex, unpredictable, emergent biological and social systems to the very logical, deterministic world of computer software is at best a dramatic oversimplification. The systems that comprise the human body range from the armies of symbiotic microbes that help us digest food in our stomachs to the consequences of using corn syrup to sweeten food to the cultural pressure associated with “size 0” celebrities. Many of those systems can’t be well modelled in their own right, let alone deterministically related to each other; let alone formally represented in an accurate, detailed way by technology systems (or even in mathematics).

We should regret and avoid the hubris that leads to the distrust of technology by overstating its capability and failing to recognise its challenges and limitations. That distrust is a barrier that prevents us from achieving the very real benefits that data and technology can bring, and that have been convincingly demonstrated in the past.

For example, an enormous contribution to our knowledge of how to treat and prevent disease was made by John Snow who used data to analyse outbreaks of cholera in London in the 19th century. Snow used a map to correlate cases of cholera to the location of communal water pipes, leading to the insight that water-borne germs were responsible for spreading the disease. We wash our hands to prevent diseases spreading through germs in part because of what we would now call the “geospatial data analysis” performed by John Snow.

Many of the insights that we seek from analytic and smart city systems are human in nature, not physical or mathematical – for example identifying when and where to apply social care interventions in order to reduce the occurrence of  emotional domestic abuse. Such questions are complex and uncertain: what is “emotional domestic abuse?” Is it abuse inflicted by a live-in boyfriend, or by an estranged husband who lives separately but makes threatening telephone calls? Does it consist of physical violence or bullying? And what is “bullying”?

IMG_0209-1

(John Snow’s map of cholera outbreaks in 19th century London)

We attempt to create structured, quantitative data about complex human and social issues by using approximations and categorisations; by tolerating ranges and uncertainties in numeric measurements; by making subjective judgements; and by looking for patterns and clusters across different categories of data. Whilst these techniques can be very powerful, just how difficult it is to be sure what these conventions and interpretations should be is illustrated by the controversies that regularly arise around “who knew what, when?” whenever there is a high profile failure in social care or any other public service.

These challenges are not limited to “high level” social, economic and biological systems. In fact, they extend throughout the worlds of physics and chemistry into the basic nature of matter and the universe. They fundamentally limit the degree to which we can measure the world, and our ability to draw insight from that information.

By being aware of these limitations we are able to design systems and practises to use data and technology effectively. We know more about the weather through modelling it using scientific and mathematical algorithms in computers than we would without those techniques; but we don’t expect those forecasts to be entirely accurate. Similarly, supermarkets can use data about past purchases to make sufficiently accurate predictions about future spending patterns to boost their profits, without needing to predict exactly what each individual customer will buy.

We underestimate the limitations and flaws of these approaches at our peril. Whilst Tim O’Reilly cites several automated financial systems as good examples of “algorithmic regulation”, the financial crash of 2008 showed the terrible consequences of the thoroughly inadequate risk management systems used by the world’s financial institutions compared to the complexity of the system that they sought to profit from. The few institutions that realised that market conditions had changed and that their models for risk management were no longer valid relied instead on the expertise of their staff, and avoided the worst affects. Others continued to rely on models that had started to produce increasingly misleading guidance, leading to the recession that we are only now emerging from six years later, and that has damaged countless lives around the world.

Every day in their work, scientists, engineers and statisticians draw conclusions from data and analytics, but they temper those conclusions with an awareness of their limitations and any uncertainties inherent in them. By taking and communicating such a balanced and informed approach to applying similar techniques in cities, we will create more trust in these technologies than by overstating their capabilities.

What follows is a description of some of the scientific, philosophical and practical issues that lead inevitability to uncertainty in data, and to limitations in our ability to draw conclusions from it:

But I’ll finish with an explanation of why we can still draw great value from data and analytics if we are aware of those issues and take them properly into account.

Three reasons why we can’t measure data perfectly

(How Heisenberg’s Uncertainty Principle results from the dual wave/particle nature of matter. Explanation by HyperPhysics at Georgia State University)

1. Heisenberg’s Uncertainty Principle and the fundamental impossibility of knowing everything about anything

Heisenberg’s Uncertainty Principle is a cornerstone of Quantum Mechanics, which, along with General Relativity, is one of the two most fundamental theories scientists use to understand our world. It defines a limit to the precision with which certain pairs of properties of the basic particles which make up the world – such as protons, neutrons and electrons – can be known at the same time. For instance, the more accurately we measure the position of such particles, the more uncertain their speed and direction of movement become.

The explanation of the Uncertainty Principle is subtle, and lies in the strange fact that very small “particles” such as electrons and neutrons also behave like “waves”; and that “waves” like beams of light also behave like very small “particles” called “photons“. But we can use an analogy to understand it.

In order to measure something, we have to interact with it. In everyday life, we do this by using our eyes to measure lightwaves that are created by lightbulbs or the sun and that then reflect off objects in the world around us.

But when we shine light on an object, what we are actually doing is showering it with billions of photons, and observing the way that they scatter. When the object is quite large – a car, a person, or a football – the photons are so small in comparison that they bounce off without affecting it. But when the object is very small – such as an atom – the photons colliding with it are large enough to knock it out of its original position. In other words, measuring the current position of an object involves a collision which causes it to move in a random way.

This analogy isn’t exact; but it conveys the general idea. (For a full explanation, see the figure and link above). Most of the time, we don’t notice the effects of Heisenberg’s Uncertainty Principle because it applies at extremely small scales. But it is perhaps the most fundamental law that asserts that “perfect knowledge” is simply impossible; and it illustrates a wider point that any form of measurement or observation in general affects what is measured or observed. Sometimes the effects are negligible,  but often they are not – if we observe workers in a time and motion study, for example, we need to be careful to understand the effect our presence and observations have on their behaviour.

2. Accuracy, precision, noise, uncertainty and error: why measurements are never fully reliable

Outside the world of Quantum Mechanics, there are more practical issues that limit the accuracy of all measurements and data.

(A measurement of the electrical properties of a superconducting device from my PhD thesis. Theoretically, the behaviour should appear as a smooth, wavy line; but the experimental measurement is affected by noise and interference that cause the signal to become "fuzzy". In this case, the effects of noise and interference - the degree to which the signal appears "fuzzy" - are relatively small relative to the strength of the signal, and the device is usable)

Theoretically, the behaviour should appear as a smooth, wavy line; but the experimental measurement is affected by noise and interference that cause the signal to become “fuzzy”. In this case, the effects of noise and interference – the degree to which the signal appears “fuzzy” – are relatively small compared to the strength of the signal, and the device is usable)

We live in a “warm” world – roughly 300 degrees Celsius above what scientists call “absolute zero“, the coldest temperature possible. What we experience as warmth is in fact movement: the atoms from which we and our world are made “jiggle about” – they move randomly. When we touch a hot object and feel pain it is because this movement is too violent to bear – it’s like being pricked by billions of tiny pins.

This random movement creates “noise” in every physical system, like the static we hear in analogue radio stations or on poor quality telephone connections.

We also live in a busy world, and this activity leads to other sources of noise. All electronic equipment creates electrical and magnetic fields that spread beyond the equipment itself, and in turn affect other equipment – we can hear this as a buzzing noise when we leave smartphones near radios.

Generally speaking, all measurements are affected by random noise created by heat, vibrations or electrical interference; are limited by the precision and accuracy of the measuring devices we use; and are affected by inconsistencies and errors that arise because it is always impossible to completely separate the measurement we want to make from all other environmental factors.

Scientists, engineers and statisticians are familiar with these challenges, and use techniques developed over the course of more than a century to determine and describe the degree to which they can trust and rely on the measurements they make. They do not claim “perfect knowledge” of anything; on the contrary, they are diligent in describing the unavoidable uncertainty that is inherent in their work.

3. The limitations of measuring the natural world using digital systems

One of the techniques we’ve adopted over the last half century to overcome the effects of noise and to make information easier to process is to convert “analogue” information about the real world (information that varies smoothly) into digital information – i.e. information that is expressed as sequences of zeros and ones in computer systems.

(When analogue signals are amplified, so is the noise that they contain. Digital signals are interpreted using thresholds: above an upper threshold, the signal means “1”, whilst below a lower threshold, the signal means “0”. A long string of “0”s and “1”s can be used to encode the same information as contained in analogue waves. By making the difference between the thresholds large compared to the level of signal noise, digital signals can be recreated to remove noise. Further explanation and image by Science Aid)

This process involves a trade-off between the accuracy with which analogue information is measured and described, and the length of the string of digits required to do so – and hence the amount of computer storage and processing power needed.

This trade-off can be clearly seen in the difference in quality between an internet video viewed on a smartphone over a 3G connection and one viewed on a high definition television using a cable network. Neither video will be affected by the static noise that affects weak analogue television signals, but the limited bandwidth of a 3G connection dramatically limits the clarity and resolution of the image transmitted.

The Nyquist–Shannon sampling theorem defines this trade-off and the limit to the quality that can be achieved in storing and processing digital information created from analogue sources. It determines the quality of digital data that we are able to create about any real-world system – from weather patterns to the location of moving objects to the fidelity of sound and video recordings. As computers and communications networks continue to grow more powerful, the quality of digital information will improve,  but it will never be a perfect representation of the real world.

Three limits to our ability to analyse data and draw insights from it

1. Gödel’s Incompleteness Theorem and the inconsistency of algorithms

Kurt Gödel’s Incompleteness Theorem sets a limit on what can be achieved by any “closed logical system”. Examples of “closed logical systems” include computer programming languages, any system for creating algorithms – and mathematics itself.

We use “closed logical systems” whenever we create insights and conclusions by combining and extrapolating from basic data and facts. This is how all reporting, calculating, business intelligence, “analytics” and “big data” technologies work.

Gödel’s Incompleteness Theorem proves that any closed logical system can be used to create conclusions that  it is not possible to show are true or false using the same system. In other words, whilst computer systems can produce extremely useful information, we cannot rely on them to prove that that information is completely accurate and valid. We have to do that ourselves.

Gödel’s theorem doesn’t stop computer algorithms that have been verified by humans using the scientific method from working; but it does mean that we can’t rely on computers to both generate algorithms and guarantee their validity.

2. The behaviour of many real-world systems can’t be reduced analytically to simple rules

Many systems in the real-world are complex: they cannot be described by simple rules that predict their behaviour based on measurements of their initial conditions.

A simple example is the “three body problem“. Imagine a sun, a planet and a moon all orbiting each other. The movement of these three objects is governed by the force of gravity, which can be described by relatively simple mathematical equations. However, even with just three objects involved, it is not possible to use these equations to directly predict their long-term behaviour – whether they will continue to orbit each other indefinitely, or will eventually collide with each other, or spin off into the distance.

(A computer simulation by Hawk Express of a Belousov–Zhabotinsky reaction,  in which reactions between liquid chemicals create oscillating patterns of colour. The simulation is carried out using “cellular automata” a technique based on a grid of squares which can take different colours. In each “turn” of the simulation, like a turn in a board game, the colour of each square is changed using simple rules based on the colours of adjacent squares. Such simulations have been used to reproduce a variety of real-world phenomena)

As Stephen Wolfram argued in his controversial book “A New Kind of Science” in 2002, we need to take a different approach to understanding such complex systems. Rather than using mathematics and logic to analyse them, we need to simulate them, often using computers to create models of the elements from which complex systems are composed, and the interactions between them. By running simulations based on a large number of starting points and comparing the results to real-world observations, insights into the behaviour of the real-world system can be derived. This is how weather forecasts are created, for example. 

But as we all know, weather forecasts are not always accurate. Simulations are approximations to real-world systems, and their accuracy is restricted by the degree to which digital data can be used to represent a non-digital world. For this reason, conclusions and predictions drawn from simulations are usually “average” or “probable” outcomes for the system as a whole, not precise predictions of the behaviour of the system or any individual element of it. This is why weather forecasts are often wrong; and why they predict likely levels of rain and windspeed rather than the shape and movement of individual clouds.

3. Some problems can’t be solved by computing machines

If I consider a simple question such as “how many letters are in the word ‘calculation’?”, I can easily convince myself that a computer programme could be written to answer the question; and that it would find the answer within a relatively short amount of time. But some problems are much harder to solve, or can’t even be solved at all.

For example, a “Wang Tile” (see image below) is a square tile formed from four triangles of different colours. Imagine that you have bought a set of tiles of various colour combinations in order to tile a wall in a kitchen or bathroom. Given the set of tiles that you have bought, is it possible to tile your wall so that triangles of the same colour line up to each other, forming a pattern of “Wang Tile” squares?

In 1966 Robert Berger proved that no algorithm exists that can answer that question. There is no way to solve the problem – or to determine how long it will take to solve the problem – without actually solving it. You just have to try to tile the room and find out the hard way.

One of the most famous examples of this type of problem is the “halting problem” in computer science. Some computer programmes finish executing their commands relatively quickly. Others can run indefinitely if they contain a “loop” instruction that never ends. For others which contain complex sequences of loops and calls from one section of code to another, it may be very hard to tell whether the programme finishes quickly, or takes a long time to complete, or never finishes its execution at all.

Alan Turing, one of the most important figures in the development of computing, proved in 1936 that a general algorithm to determine whether or not any computer programme finishes its execution does not exist. In other words, whilst there are many useful computer programmes in the world, there are also problems that computer programmes simply cannot solve.

(A set of Wang Tiles, and a pattern created by tiling them so that tiles are placed next to other tiles so that their edges have the same colour. Given any particular set of tiles, it is impossible to determine whether such a pattern can be created by any means other than trial and error)

(A set of Wang Tiles, and a pattern of coloured squares created by tiling them. Given any random set of tiles of different colour combinations, there is no set of rules that can be relied on to determine whether a valid pattern of coloured squares can be created from them. Sometimes, you have to find out by trial and error. Images from Wikipedia)

Five reasons why the human world is messy, unpredictable, and can’t be perfectly described using data and logic

1. Our actions create disorder

The 2nd Law of Thermodynamics is a good candidate for the most fundamental law of science. It states that as time progresses, the universe becomes more disorganised. It guarantees that ultimately – in billions of years – the Universe will die as all of the energy and activity within it dissipates.

An everyday practical consequence of this law is that every time we act to create value – building a shed, using a car to get from one place to another, cooking a meal – our actions eventually cause a greater amount of disorder to be created as a consequence – as noise, pollution, waste heat or landfill refuse.

For example, if I spend a day building a shed, then to create that order and value from raw materials, I consume structured food and turn it into sewage. Or if I use an electric forklift to stack a pile of boxes, I use electricity that has been created by burning structured coal into smog and ash.

So it is literally impossible to create a “perfect world”. Whenever we act to make a part of the world more ordered, we create disorder elsewhere. And ultimately – thankfully, long after you and I are dead – disorder is all that will be left.

2. The failure of Logical Atomism: why the human world can’t be perfectly described using data and logic

In the 20th Century two of the most famous and accomplished philosophers in history, Bertrand Russell and Ludwig Wittgenstein, invented “Logical Atomism“, a theory that the entire world could be described by using “atomic facts” – independent and irreducible pieces of knowledge – combined with logic.

But despite 40 years of work, these two supremely intelligent people could not get their theory to work: “Logical Atomism” failed. It is not possible to describe our world in that way.

One cause of the failure was the insurmountable difficulty of identifying truly independent, irreducible atomic facts. “The box is red” and “the circle is blue”, for example, aren’t independent or irreducible facts for many reasons. “Red” and “blue” are two conventions of human language used to describe the perceptions created when electro-magnetic waves of different frequencies arrive at our retinas. In other words, they depend on and relate to each other through a number of sophisticated systems.

Despite centuries of scientific and philosophical effort, we do not have a complete understanding of how to describe our world at its most basic level. As physicists have explored the world at smaller and smaller scales, Quantum Mechanics has emerged as the most fundamental theory for describing it – it is the closest we have come to finding the “irreducible facts” that Russell and Wittgenstein were looking for. But whilst the mathematical equations of Quantum Mechanics predict the outcomes of experiments very well, after nearly a century, physicists still don’t really agree about what those equations mean. And as we have already seen, Heisenberg’s Uncertainty Principle prevents us from ever having perfect knowledge of the world at this level.

Perhaps the most important failure of logical atomism, though, was that it proved impossible to use logical rules to turn “facts” at one level of abstraction – for example, “blood cells carry oxygen”, “nerves conduct electricity”, “muscle fibres contract” – into facts at another level of abstraction – such as “physical assault is a crime”. The human world and the things that we care about can’t be described using logical combinations of “atomic facts”. For example, how would you define the set of all possible uses of a screwdriver, from prising the lids off paint tins to causing a short-circuit by jamming it into a switchboard?

Our world is messy, subjective and opportunistic. It defies universal categorisation and logical analysis.

3. The importance and inaccessibility of “local knowledge” 

Because the tool we use for calculating and agreeing value when we exchange goods and services is money, economics is the discipline that is often used to understand the large-scale behaviour of society. We often quantify the “growth” of society using economic measures, for example.

But this approach is notorious for overlooking social and environmental characteristics such as health, happiness and sustainability. Alternatives exist, such as the Social Progress Index, or the measurement framework adopted by the United Nations 2014 Human Development Report on world poverty; but they are still high level and abstract.

Such approaches struggle to explain localised variations, and in particular cannot predict the behaviours or outcomes of individual people with any accuracy. This “local knowledge problem” is caused by the fact that a great deal of the information that determines individual actions is personal and local, and not measurable at a distance – the experienced eye of the fruit buyer assessing not just the quality of the fruit but the quality of the farm and farmers that produce it, as a measure of the likely consistency of supply; the emotional attachments that cause us to favour one brand over another; or the degree of community ties between local businesses that influence their propensity to trade with each other.

Sharing economy” business models that use social media and reputation systems to enable suppliers and consumers of goods and services to find each other and transact online are opening up this local knowledge to some degree. Local food networks, freecycling networks, and land-sharing schemes all use this technology to the benefit of local communities whilst potentially making information about detailed transactions more widely available. And to some degree, the human knowledge that influences how transactions take place can be encoded in “expert systems” which allow computer systems to codify the quantitative and heuristic rules by which people take decisions.

But these technologies are only used in a subset of the interactions that take place between people and businesses across the world, and it is unlikely that they’ll become ubiquitous in the foreseeable future (or that we would want them to become so). Will we ever reach the point where prospective house-buyers delegate decisions about where to live to computer programmes operating in online marketplaces rather than by visiting places and imagining themselves living there? Will we somehow automate the process of testing the freshness of fish by observing the clarity of their eyes and the freshness of their smell before buying them to cook and eat?

In many cases, while technology may play a role introducing potential buyers and sellers of goods and services to each other, it will not replace – or predict – the human behaviours involved in the transaction itself.

(Medway Youth Trust use predictive and textual analytics to draw insight into their work helping vulnerable children. They use technology to inform expert case workers, not to take decisions on their behalf.)

4. “Wicked problems” cannot be described using data and logic

Despite all of the challenges associated with problems in mathematics and the physical sciences, it is nevertheless relatively straightforward to frame and then attempt to solve problems in those domains; and to determine whether the resulting solutions are valid.

As the failure of Logical Atomism showed, though, problems in the human domain are much more difficult to describe in any systematic, complete and precise way – a challenge known as the “frame problem” in artificial intelligence. This is particularly true of “wicked problems” – challenges such as social mobility or vulnerable families that are multi-faceted, and consist of a variety of interdependent issues.

Take job creation, for example. Is that best accomplished through creating employment in taxpayer-funded public sector organisations? Or by allowing private-sector wealth to grow, creating employment through “trickle-down” effects? Or by maximising overall consumer spending power as suggested by “middle-out” economics? All of these ideas are described not using the language of mathematics or other formal logical systems, but using natural human language which is subjective and inconsistent in use.

The failure of Logical Atomism to fully represent such concepts in formal logical systems through which truth and falsehood can be determined with certainty emphasises what we all understand intuitively: there is no single “right” answer to many human problems, and no single “right” action in many human situations.

5. Behavioural economics and the caprice of human behaviour

Behavioural economics” attempts to predict the way that humans behave when taking choices that have a measurable impact on them – for example, whether to put the washing machine on at 5pm when electricity is expensive, or at 11pm when it is cheap.

But predicting human behaviour is notoriously unreliable.

For example, in a smart water-meter project in Dubuque, Iowa, households that were told how their water conservation compared to that of their near neighbours were found to be twice as likely to take action to improve their efficiency as those who were only told the details of their own water use. In other words, people who were given quantified evidence that they were less responsible water user than their neighbours changed their behaviour. OPower have used similar techniques to help US households save 1.9 terawatt hours of power simply by including a report based on data from smart meters in a printed letter sent with customers’ electricity bills.

These are impressive achievements; but they are not always repeatable. A recycling scheme in the UK that adopted a similar approach found instead that it lowered recycling rates across the community: households who learned that they were putting more effort into recycling than their neighbours asked themselves “if my neighbours aren’t contributing to this initiative, then why should I?”

Low carbon engineering technologies like electric vehicles have clearly defined environmental benefits and clearly defined costs. But most Smart Cities solutions are less straightforward. They are complex socio-technical systems whose outcomes are emergent. Our ability to predict their performance and impact will certainly improve as more are deployed and analysed, and as University researchers, politicians, journalists and the public assess them. But we will never predict individual actions using these techniques, only the average statistical behaviour of groups of people. This can be seen from OPower’s own comparison of their predicted energy savings against those actually achieved – the predictions are good, but the actual behaviour of OPower’s customers shows a high degree of apparently random variation. Those variations are the result of the subjective, unpredictable and sometimes irrational behaviour of real people.

We can take insight from Behavioural Economics and other techniques for analysing human behaviour in order to create appropriate strategies, policies and environments that encourage the right outcomes in cities; but none of them can be relied on to give definitive solutions to any individual person or situation. They can inform decision-making, but are always associated with some degree of uncertainty. In some cases, the uncertainty will be so small as to be negligible, and the predictions can be treated as deterministic rules for achieving the desired outcome. But in many cases, the uncertainty will be so great that predictions can only be treated as general indications of what might happen; whilst individual actions and outcomes will vary greatly.

(Of course it is impossible to predict individual criminal actions as portrayed in the film “Minority Report”. But is is very possible to analyse past patterns of criminal activity, compare them to related data such as weather and social events, and predict the likelihood of crimes of certain types occurring in certain areas. Cities such as Memphis and Chicago have used these insights to achieve significant reductions in crime)

Learning to value insight without certainty

Mathematics and digital technology are incredibly powerful; but they will never perfectly and completely describe and predict our world in human terms. In many cases, our focus for using them should not be on automation: it should be on the enablement of human judgement through better availability and communication of information. And in particular, we should concentrate on communicating accurately the meaning of information in the context of its limitations and uncertainties.

There are exceptions where we automate systems because of a combination of a low-level of uncertainty in data and a large advantage in acting autonomously on it. For example, anti-lock braking systems save lives by using automated technology to take thousands of decisions more quickly than most humans would realise that even a single decision needed to be made; and do so based on data with an extremely low degree of uncertainty.

But the most exciting opportunity for us all is to learn to become sophisticated users of information that is uncertain. The results of textual analysis of sentiment towards products and brands expressed in social media are far from certain; but they are still of great value. Similar technology can extract insights from medical research papers, case notes in social care systems, maintenance logs of machinery and many other sources. Those insights will rarely be certain; but properly assessed by people with good judgement they can still be immensely valuable.

This is a much better way to understand the value of technology than ideas like “perfect knowledge” and “algorithmic regulation”. And it is much more likely that people will trust the benefits that we claim new technologies can bring if we are open about their limitations. People won’t use technologies that they don’t trust; and they won’t invest their money in them or vote for politicians who say they’ll spend their taxes on it.

Thankyou to Richard Brown and Adrian McEwen for discussions on Twitter that helped me to prepare this article. A more in-depth discussion of some of the scientific and philosophical issues I’ve described, and an exploration of the nature of human intelligence and its non-deterministic characteristics, can be found in the excellent paper “Answering Descartes: Beyond Turing” by Stuart Kauffman published by MIT press.

12 simple technologies for cities that are Smart, open and fair

(Fritz Lang’s 1927 dystopian film Metropolis pictured a city that exploited futuristic technologies, but only on behalf of a minority of its citizens. Image by Breve Storia del Cinema)

Efficiency; resilience; growth; vitality. These are all characteristics that cities desire, and that are regularly cited as the objectives of Smarter City programmes and other forward-looking initiatives.

But, though it is less frequently stated, a more fundamental objective underlies all of these: fairness.

The Nobel Prize-winning economist Joseph Stiglitz has written extensively about the need to prioritise fairness as a policy and investment objective in a world that in many areas – and in many cities – is becoming more unequal. That inequality is demonstrated by the difference in life expectancy of 20 years or so that exists between the poorest and richest parts of many UK cities.

I think the Smart Cities movement will only be viewed as a success by the wider world if it contributes to redressing that imbalance.

So how do we design Smart City systems that employ technology to make cities more successful, resilient and efficient; in a way that distributes resources and creates opportunities more fairly than today?

One answer to that question is that the infrastructures and institutions of such cities should be open to citizens and businesses: accessible, understandable, adaptable and useful.

Why do we need open cities?

In the wonderful “Walkable City“, Jeff Speck describe’s the epidemiologist Richard Jackson’s stark realisation of the life-and-death significance of good urban design. Jackson was driving along a notorious 2 mile stretch of Atlanta’s 7-lane Buford highway with no pavements or junctions:

There, by the side of the road, in the ninety-five degree afternoon, he saw a woman in her seventies, struggling under the burden of two shopping bags. He tried to relate her plight to his own work as an epidemiologist. “If that poor woman had collapsed from heat stroke, we docs would have written the cause of death as heat stroke and not lack of trees and public transportation, poor urban form, and heat-island effects. If she had been killed by a truck going by the cause of death would have been “motor vehicle trauma”, and not lack of sidewalks and transit, poor urban planning and failed political leadership.”

(Pedestrian’s attempting to cross Atlanta’s notorious Buford Highway; a 7-lane road with no pavements and 2 miles between junctions and crossings. Photo by PBS)

Buford Highway is an infrastructure fit only for vehicles, not for people. It allows no safe access along or across it for the communities it passes through – it is closed to them, unless they risk their lives.

At the same time that city leaders are realising more and more that better planning is needed to create more equal cities, so it  is imperative that the digital infrastructures we deploy in cities are accessible and useful to citizens, not as dangerous to them as Buford Highway.

Unfortunately, there are already examples of city infrastructures using technologies that are poorly designed, that fail to serve the needs of  communities, or that fail in operation.

For instance, a network of CCTV cameras in Birmingham were eventually dismantled after it was revealed they had been erected to gather evidence of terrorist activities in Birmingham’s Muslim communities, rather than in support of their safety. And there have been many examples of the failure of both public sector agencies and private companies to properly safeguard the data they hold about citizens.

Market failures can result in the benefits of technology being more accessible to wealthier communities than poorer communities. For example,  private sector network providers will not deploy connectivity in areas which are insufficiently economically active for them to make a profit, and Government funding is not yet sufficient to close the gap. And community lenders, who typically offer loans at one-tenth to one-hundredth the cost of payday lenders, have so far lacked the resources to invest in the online technology that makes some payday loans so easy to take out – though this is starting to change.

One of the technology industry’s most notorious failures, the Greyhound Lines bus company’s 1993 “Trips” reservations system, made a city service – bus transport – unusable. The system was intended to make it quicker and easier for ticket agents to book customers onto Greyhound’s buses. But it was so poorly designed and operated so slowly that passengers missed their buses whilst they stood in line waiting for their tickets; were separated from their luggage; and in some cases were stranded overnight in bus terminals.

In the 21st Century, badly applied digital technology will create bad cities, just as badly designed roads and buildings did in the last century.

Smart Cities for the digitally disconnected

It’s possible to benefit from Smart city infrastructures without being connected to the internet or having skills in digital technology – Stockholm’s road-use charging scheme reduces congestion and pollution for everyone in the city, for example.

But the benefits of many Smart systems are dependent on being connected to the internet and having the skills to use it. From the wealth of educational material now available online (from the most sophisticated Harvard University courses to the most basic tutorials on just about any subject available on YouTube), to the increasing role of technology in high-paid careers, it’s absolutely obvious that the ability to access and use the internet and digital technologies in the future will be a crucial component of a successful life.

Smart cities won’t be fair cities if we take connectivity and skills for granted. Worldwide, fully one-third of the population has never been online; and even in as rich and advanced a country as the United Kingdom, 18% of adults – a fifth of the voting population – have never used the internet. At the risk of generalising a complex issue, many of those people will be those that Smart City services should create benefits for if they are to contribute to making cities fairer.

After legal challenges from private sector providers, the UK Government’s plan to assist cities in funding the deployment of ubiquitous broadband connectivity has been replaced by a voucher scheme that subsidises businesses connecting to existing networks. The scheme will not now directly help to improve broadband coverage in those areas that are poorly served because they are economically relatively inactive – precisely the areas that need the most help.

There’s been a lot of discussion of “net neutrality” recently – the principle that on the Internet, all traffic is equal, and that there is no way to pay for certain data to be treated preferentially. The principle is intended to ensure that the benefits of the internet are equally available to everyone.

But net neutrality is irrelevant to those who can’t access the internet at all; and the free market is already bypassing it in some ways. Network providers who control the local infrastructures that connect homes and businesses to the internet are free to charge higher prices for faster connections. Wealthy corporations and governments can bypass parts of the internet entirely with their own international cable networks through which they can route traffic between users on one continent and content on another.

Governments in emerging economies are building new cities to house their rapidly urbanising populations with ubiquitous, high-speed connectivity from the start. The Australian government is investing the profits from selling raw materials to support that construction boom in providing broadband coverage across the entire country. The least wealthy areas of European cities will be further disadvantaged compared to them unless we can find ways to invest in their digital infrastructure without contravening the European Union’s “State aid” law.

Technology as if people mattered

The UK’s Government Digital Service employ an excellent set of agile, user-centric design principles that are intended to promote the development of Smarter, digitally-enabled services that can be accessed by anyone anywhere who needs them, regardless of their level of skill with digital technology or ability to access the Internet.

The principles include: “Start with needs”; “Do the hard work to make it simple”; “Build for inclusion”; “Understand context”; and “Build digital services, not websites”.

A good example of following these principles and designing excellent, accessible digital services using common sense is the London Borough of Newham. By concentrating on the delivery of services through mobile telephones – which are much more widely owned than PCs and laptops – and on contexts in which a friend or family member assists the ultimate service user, Newham have achieved a remarkable shift to online services in one of London’s least affluent boroughs, home to many communities and citizens without access to broadband connectivity or traditional computers.

Similar, low-tech innovations in designing systems that people find useful can be found in some smart meter deployments.

In principle, the analytic technology in smart meters can provide insights that helps households and businesses reduce energy usage – identifying appliances that are operating inefficiently, highlighting leaks, and comparing households’ energy usage to that of their neighbours.

But most people don’t want to look at smart meter displays or consult a computer before they put the washing on or have a shower.

In one innovative project in the village of Chale, these issues were overcome by connecting analytic technology to a glow globe in the lounge – the globe simply glows red, orange or green depending on whether too much energy is being used compared to that expected for the time of day and year. A similarly effective but even more down-to-earth approach was adopted by OPower in the US who reported that they have helped households save 1.9 terawatt hours of power simply by including a report based on data from smart meters in a printed letter sent with customers’ electricity bills.

There are countless other examples. During peak traffic periods, Dublin’s “Live Drive” radio station plays a mixture of 80s pop music and traffic information derived from sophisticated analytics developed by IBM’s Smarter Cities Research team based on data from road sensors and GPS beacons in the city’s buses. And in India’s rural Karnataka region, which lacks internet infrastructure and where many workers lack literacy skills, let alone access to computers and smartphones, the benefits of online job portals have been recreated using “spoken web” technology using the existing traditional analogue telephone network.

In Kenya, Kilimo Salama has made crop insurance affordable for subsistence farmers by using remote weather monitoring to trigger payouts via Safaricom’s M-Pesa mobile payments service, rather than undertaking expensive site visits to assess claims. And the SMS for Life project in Tanzania uses the cheap and widely used SMS infrastructure to create a dynamic, collaborative supply chain for medicine between rural pharmacists.

These are all examples of what was originally described as “Intermediate Technology” by the economist Ernst Friedrich “Fritz” Schumacher in his influential work, “Small is Beautiful: Economics as if People Mattered“, and is now known as Appropriate Technology.

12 “appropriate technologies” for Smart Cities

Schumacher’s views on technology were informed by his belief that our approach to economics should be transformed “as if people mattered”. He asked:

What happens if we create economics not on the basis of maximising the production of goods and the ability to acquire and consume them – which ends up valuing automation and profit – but on the Buddhist definition of the purpose of work: “to give a man a chance to utilise and develop his faculties; to enable him to overcome his ego-centredness by joining with other people in a common task; and to bring forth the goods and services needed for a becoming existence.”

Schumacher pointed out that the most advanced technologies, to which we often look to create value and growth, are in fact only effective in the hands of those with the resources and skills required to use them- i.e. those who are already wealthy; and that by emphasising efficiency, output and profit they tend to further concentrate economic value in the hands of the wealthy – often specifically by reducing the employment of people with less advanced skills and roles.

In contrast, Schumacher felt that the most genuine “development ” of our society would occur when the most possible people were employed in a way that gave them the practical ability to earn a living ; and that also offered a level of human reward – much as Maslow’s “Hierarchy of Needs” first identifies our most basic requirements for food, water, shelter and security; but next relates the importance of family, friends and “self-actualisation” (which can crudely be described as the process of achieving things that we care about).

This led him to ask:

What is that we really require from the scientists and technologists? I should answer:

We need methods and equipment which are:

    • Cheap enough so that they are accessible to virtually everyone;
    • Suitable for small-scale application; and
    • Compatible with man’s need for creativity

(Maslow’s Hierarchy of Needs, image by Factoryjoe via Wikimedia Commons)

I can’t think of a more powerful set of tools that reflect these characteristics than the digital technologies that have emerged over the past decade, such as social media, smartphones, Cloud computing and Open Data. They provide a digital infrastructure of appropriate technologies that are accessible to everyone, but that connect with the large scale city infrastructures that support millions of urban lives; and they give citizens, communities and businesses the ability to adapt city infrastructures to their own needs.

I can think of at least 12 such technologies that are particularly important; and that fall into the categories of “Infrastructures that matter”; “Technologies for everyone”; and “The keys to the city”.

Infrastructures that matter

1.Broadband connectivity

I’ve covered the importance of broadband connectivity, and the challenges involved in providing it ubiquitously, already, so I won’t go into detail again here. But whether it’s fixed-line, mobile or wi-fi, its benefits are becoming so significant that it can’t be omitted.

2. Cloud computing

Before Cloud computing, anyone who wanted to develop a computing system for others to use had to invest up-front in an infrastructure capable of operating the service to a reasonable level of reliability. Cloud computing provides a much easier, cheaper alternative: rent a little bit of someone else’s infrastructure. And if your service becomes popular, don’t worry about carrying out complex and costly upgrades, just rent a little more.

Cloud computing has helped to democratise digital services by making it  it dramatically easier and cheaper for anyone to create and offer them.

Technologies for everyone

3. Mobile and Smart phones

In 2013, the number of cellphone subscriptions worldwide surpassed the number of people who have ever owned fixed line telephones.

In the developed world, we’re conscious of the increasing power of Smartphones; and Councils such as Newham are exploiting the fact that many people who lack the desire or resources to purchase a computer and a broadband connection possess and use relatively sophisticated Smartphones through which they access digital services and content.

But in some countries in the developing world, the real story is simply the availability of the first basic infrastructure – voice calls and SMS – that’s available to almost everyone, everywhere. According to one report, access to a basic mobile phone is more common than access to a toilet with proper drainage. In his TEDGlobal 2013 talk, Toby Shapshak described how entire business infrastructures and supply chains are being built upon SMS and similiarly “appropriate” technologies – to the extent that 4o% of Kenya’s GDP now passes through the M-Pesa mobile payments service offered by Safaricom. Banks, technology entrepreneurs, governments and others in the developed world are looking to this wave of innovation as a source of new ideas.

4. Social media

In his 2011 book “Civilization“, Niall Fergusson comments that news of the Indian Mutiny in 1857 took 46 days to reach London, travelling in effect at 3.8 miles an hour. By Jan 2009 when US Airways flight 1549 crash landed in the Hudson river, Jim Hanrahan’s message on Twitter communicated the news to the entire world four minutes later; it reached Perth, Australia at more than 170,000 miles an hour.

Social media is the tool that around a quarter of the world’s population now simply uses to stay in touch with friends and family at this incredible speed.

At a recent Mayoral debate on Smarter Cities, Ridwan Kamil, Mayor of Bandung, Indonesia, described how he has nurtured an atmosphere of civic engagement, trust and transparency by encouraging his staff to connect with the city’s 2.3 million Twitter-using citizens through social media. By encouraging citizens to report issues online and by publishing details of city spending, Mayor Kami has helped to combat corruption and improve public services. Montpellier in France is engaging with citizens through social media in a similar way, asking them to explore data about their city and suggest ways to improve it. And the ambitious control room set up in Rio de Janeiro by Mayor Eduardo Paes to help manage the city during the current World Cup uses social media not just as one of the information feeds that provides insight into what is happening in the city, but to keep citizens as well informed as possible.

The “Community Lovers Guide“, of which 60 editions have now been published across the world, contains stories of people and projects that have improved their communities. The guide is not concerned directly with technology; but many of the initiatives that it describes have used social media as a tool for engaging with stakeholders and supporters.

And we increasingly use social media to conduct business. From e-Bay to Uber, social media is being used to create “sharing economy” business models that replace traditional sales channels and supply chains with networks of peer-to-peer transactions in industries from financial services to agriculture to distribution to retail. Nearly 2 billion of us now regularly use the technologies that allow us to participate in those trading networks.

5. The touchscreen

Three years ago, I watched my then 2-year-old son teach himself how to use a touchscreen tablet to watch cartoons from around the world. He is a member of the first generation to grow up with the world’s information literally at their fingertips before they can read and write.

The simplicity of the touchscreen has already led to the adoption of tablet computers by huge numbers of people who would never have so willingly chosen to use a laptop computer and keyboard. As touchscreens and the devices that use them become cheaper and cheaper, many more people who currently don’t choose to access online content and services will do so without realising it, simply by interacting with the world around them.

We will rapidly develop even more intimate interfaces to technology. Three years ago, scientists at the University of Berkely used computers attached to an MRI scanner to recreate moving images from the magnetic field created by the brain of a person inside the scanner watching a film on a pair of goggles. And last year, scientists at the University of Washington used similar technology to allow one of them to move the other’s arm simply by thinking about it. Whilst it will take time for these technologies to become widely available – and there are certainly ethical issues concerning their use that must be addressed in the process – eventually they will make an important contribution to making information and the ability to communicate widely even more accessible than today.

6. Open Source software

Open Source software is one of the very few technologies that is free in principle to anyone with the time to understand how to use it. It is not free in the medium or long-term – most organisations that use it pay for some form of support or maintenance to be carried out on their Open Source systems. But it is free to get started, and the Open Source community is a great place to get help and advice whilst doing so.

My colleagues around the world work very hard to ensure that IBM’s technologies support open source technology, from interoperating with the MySQL database and CKAN open data portal; to donating IBM-developed technologies such as Eclipse, MQTT and Node-RED to the Open Source community; to IBM’s new “BlueMix” Cloud computing platform for developers which is built from Open Source technology and offers developers 50 pre-built services for inclusion in their Apps, many of which are open source.

Not all technology is Open Source, and there are good reasons why many technology companies large and small invest in developing products and services for cities that use proprietary software – often, simply to protect their investment. For as long as those products and services offer valuable capabilities that are not available as open source software, cities will use them.

But it is vital that city systems incorporating those technologies are nevertheless open for use by open source software, simply to make them as widely accessible as possible for people who need to adapt them to their own needs.

7. Intelligent hardware

The emergence of the internet as a platform for enabling sales, marketing and logistics over the last decade has enabled small and micro-businesses to reach markets across the world that were previously accessible only to much larger organisations with international sales and distribution networks.

More recently, the emergence and maturation of technologies such as 3D printingopen-source manufacturing and small-scale energy generation are enabling small businesses and community initiatives to succeed in new sectors by reducing the scale at which it is economically viable to carry out what were previously industrial activities – a trend recently labelled by the Economist magazine as the “Third Industrial Revolution“.

Arduino, an Open Source electronics prototyping platform, and the Raspberry Pi, a cheap and simple computer intended to simplify the process of teaching programming skills, provide very easy introductions to these technologies; and organisations such as Hub Launchpad and TechShop make it possible for entrepreneurs and small businesses to explore them in more depth.

The keys to the city

8. Open APIs 

An “API” is an “Application Programming Interface“: it is a tool that allows one computer system – such as an Open Source “app” written by an entrepreneur or social innovator – to use the information and capabilities of another computer system – such as a traffic information system for a city’s transport network.

For example, Amazon make an API available to developers that exposes all of the capabilities of Amazon Marketplace – from listing products, to changing prices to despatching goods to customers. Whilst these features are not free to use, they offer one way for businesses to create new online shops extremely quickly,  linked to a fulfilment operation to support them.

Open APIs are a tool that can make digital city infrastructures open to local innovation, and allow citizens, businesses and communities to adapt them to their own needs. For instance, Birmingham’s Droplet, a SmartPhone payment service that encourages local economic growth by making it easy to pay for goods and services from local merchants, offer a developer API to allow their fast, cheap payments system to be included in other city services.

A Smarter City infrastructure whose IT systems offer APIs to citizens, communities and businesses can be accessed and adapted by them. It is the very opposite of Atlanta’s Buford Highway.

9. Open Data

The Open Data movement champions the principle that any non-sensitive data from public services and infrastructures should be freely and openly available. Most such data is not currently available in this form – either because the organisations operating those services have yet to adopt the principle, or because the computer systems they use simply were not designed to make data available.

There are many reasons to support the idea of Open Data. McKinsey estimate its economic value to be at least $3 trillion per year, for example.

But perhaps more importantly, Open Data is a fundamental tool for democracy and transparency in a digital age. Niall Firth’s November 2013 editorial for the New Scientist magazine describes how citizens of developing nations are using open data to hold their governments to account, from basic information about election candidates to the monitoring of government spending.

The “Dublinked” information sharing partnership, in which Dublin City Council, three surrounding local authorities and  service providers to the city share information and make it available to their communities as “open data”, is a good example of the benefits that openness can bring. Dublinked now makes 3,000 datasets available to local authority analysts; to researchers from IBM Research and the National University of Ireland; and to businesses, entrepreneurs and citizens. The partnership is identifying new ways for the city’s public services and transport, energy and water systems to work; and enabling the formation of new, information-based businesses with the potential to export the solutions they develop in Dublin to cities internationally. It is putting the power of technology and of city information not only at the disposal of the city authority and its agencies, but also into the hands of communities and innovators.

10. Open Standards

Open Data and Open APIs will only be widely used and effective in cities across the world if they conform to Open Standards that mean that everyone, everywhere can use them in the same way.

In order to do something as simple as changing a lightbulb, we rely on open standards for the levels of voltage and power from our electricity supply; the physical dimensions of the socket and bulb and the characteristics of their fastenings; specifications of the bulb’s light and heat output; and the tolerance of the bulb and the fitting for the levels of moisture found in bathrooms and kitchens. Cities are much more complicated than lightbulbs; and many more standards will be required on order for us to connect to and re-configure their systems easily and reliably.

Open standards are also an important tool in avoiding city systems becoming “locked-in” to any particular supplier. By specifying common characteristics that all systems are required to demonstrate, it becomes more straightforward to exchange one supplier’s implementation for another.

Some standards that Smarter City infrastructures can use are already in place – for example, Web services and REST that specify the general ways in which computer systems interact, and the Common Alerting Protocol which is more specific to interactions between systems that monitor and control the physical world. But many others will need to be invented and encouraged to spread. The City Protocol Society is one organisation seeking to develop those new standards; and the British Standards Institute recently published the first set of national standards for Smarter Cities in the UK, including a standard for the interoperability of data between Smart City systems.

11. Local and virtual currencies and trading systems

Local trading systems use paper or electronic currencies that are issued and accepted within a particular place or region. They influence people and businesses to spend the money that they earn locally, thereby promoting regional economic synergies.

Examples include the Bristol Pound; the Droplet smartphone payment scheme in Birmingham; and schemes based on the bartering of goods, money, time and services, such as time banking. Some schemes combine both elements – in Switzerland, a complementary currency, the Wir , has contributed to economic stability over the last century by allowing some debt repayments to be bartered locally when they cannot be repaid in universal currency.

As these schemes develop – and in particular as they adopt technologies such as smartphones and Open APIs – they are increasingly being used as an infrastructure for Smarter City projects in domains such as transport, food supply and energy.

Smarter Cities will succeed at scale when we discover the business models that convert financial payments and investments into social, economic and environmental improvements in the places where we live and work. I can’t think of a more directly applicable tool for designing those business models than flexible, locally focussed currencies and payment infrastructures.

12. Identity stores

In order to use digital services, we have to provide personal information online. What happens to that personal information once we have finished using the service?

Social networks such as Facebook regularly cause controversy when they experiment with new ways to use the data that we freely share with them; often granting them extensive rights over that data in the process.

Our use of technologies such as social media, Smartphones and APIs creates a mass of data about us that is often retained by the operators of the services we use. Sometimes this is as a result of deliberate actions:  when we share geo-tagged photos through social media, for example. In other cases, it is incidental. The location and movement of GPS sensors in our smartphones is anonymised by our network providers and aggregated with that of others nearby who are moving similarly. It is then sold to traffic information services, so that they can sell it back to us through the satellite navigation systems in our cars to help us to avoid traffic congestion.

Organisations of all types and sizes are competing for the new markets and opportunities of the information economy that are created, in part, by this increased availability of personal information. That is simply the natural consequence of the emergence of a new resource in a competitive economy. But it is also true that as the originators of much of that information, and as the ultimate stakeholders in that economy, we should seek to establish an equitable consensus between us for how our information is used.

A different approach is being taken by organisations such as MyDex. MyDex are a Community Interest Company (CIC) who have created a platform that allows users to securely share personal information with digital service providers when they need to; but to revoke access when they have finished using the service.

Incorporation as a Community Interest Company allows MyDex:

“… to be sustainable and requires it be run for community benefit. Crucially, the CIC assets and the majority of any profits must be used for the community purposes for which Mydex is established. Its assets cannot be acquired by another party to which such restrictions do not apply.”

(From the MyDex website, http://mydex.org/about/ensuring-trust/).

As a result of both the security of their technology solution and the clarity with which personal and community interests are reflected in their business model, MyDex’s platform is now being used by a variety of public sector and community organisations to offer a personal data store to the people they support.

MyDex’s approach to creating trust in the use of personal data is not the only one, but it is a good example of a business model that explicitly addresses and prioritises the interests of the individual.

Smart Digital Urbanism

Architects and city planners such as Kelvin Campbell, founder of the Smart Urbanism movement and Jan Gehl, who inspired the “human-scale cities” movement have been identifying the fine-grained physical characteristics of large-scale urban environments that encourage vibrant communities and successful economies through the daily activities of people, families, communities and businesses.

A good example is provided by Edinburgh’s “New Town”, regarded as a masterpiece of urban planning that has proved adaptable and successful through the economic and social changes of the past 250 years. It has frequent road crossings, junctions and side-streets that slow down traffic; provides stopping opportunities for traffic and crossing opportunities for people, encouraging businesses to thrive; and has a mixture of small and large premises for a variety of businesses to occupy.

Smarter cities will not be fairer cities unless we identify and employ technologies for building them that create similar openness and accessibility for digital services and information. That’s precisely what I think Open Data, mobile phones, virtual currencies and the other technologies I’ve described in this article can achieve.

I can’t think of a more exciting idea than using them to address the economic, social and environmental challenge of our time and to build better cities and communities for tomorrow.

What’s the risk of investing in a Smarter City?

(The two towers of the Bosco Verticale in Milan will be home to more than 10,000 plants that create shade and improve air quality. But to what degree do such characteristics make buildings more attractive to potential tenants than traditional structures, creating the potential to create financial returns to reward more widespread investment in this approach? Photo by Marco Trovo)

(Or “how to buy a Smarter City that won’t go bump in the night”)

There are good reasons why the current condition and future outlook of the world’s cities have been the subject of great debate in recent years. Their population will double from 3 billion to 6 billion by 2050; and while those in the developing world are growing at such a rate that they are challenging our ability to construct resilient, efficient infrastructure, those in developed countries often have significant levels of inequality and areas of persistent poverty and social immobility.

Many people involved in the debate are convinced that new approaches are needed to transport, food supply, economic development, water and energy management, social and healthcare, public safety and all of the other services and infrastructures that support cities.

As a consequence, analysts such as Frost & Sullivan have estimated that the market for “Smart City” solutions that exploit technology to address these issues will be $1.5trillion by 2020.

But anyone who has tried to secure investment in an initiative to apply “smart” technology in a city knows that it is not always easy to turn that theoretical market value into actual investment in projects, technology, infrastructure and expertise.

It’s not difficult to see why this is the case. Most investments are made in order to generate a financial return, but profit is not the objective of “Smart Cities” initiatives: they are intended to create economic, environmental or social outcomes. So some mechanism – an investment vehicle, a government regulation or a business model – is needed to create an incentive to invest in achieving those outcomes.

Institutions, Business, Infrastructure and Investment

Citizens expect national and local governments to use their tax revenues to deliver these objectives, of course. But they are also very concerned that the taxes they pay are spent wisely on programmes with transparent, predictable, deliverable outcomes, as the current controversy over the UK’s proposed “HS2” high speed train network and previous controversies over the effectiveness of public sector IT programmes show.

Nevertheless, the past year has seen a growing trend for cities in Europe and North America to invest in Smart Cities technologies from their own operational budgets, on the basis of their ability to deliver cost savings or improvements in outcomes.

For example, some cities are replacing traditional parking management and enforcement services with “smart parking” schemes that are reducing congestion and pollution whilst paying for themselves through increased enforcement revenues. Others are investing their allocation of central government infrastructure funds in Smart solutions – such as Cambridge, Ontario’s use of the Canadian government’s Gas Tax Fund to invest in a sensor network and analytics infrastructure to manage the city’s physical assets intelligently.

The providers of Smart Cities solutions are investing too, by implementing their services on Cloud computing platforms so that cities can pay incrementally for their use of them, rather than investing up-front in their deployment. Minneapolis, Minnesota and Montpelier, France, recently announced that they are using IBM’s Cloud-based solutions for smarter water, transport and emergency management in this way. And entrepreneurial businesses, backed by Venture Capital investment, are also investing in the development of new solutions.

However, we have not yet tapped the largest potential investment streams: property and large-scale infrastructure. The British Property Federation, for example, estimates that £14 billion is invested in the development of new property in the UK each year. For the main part, these investment streams are not currently investing  in “Smart City” solutions.

To understand why that is the case – and how we might change it – we need to understand the difference in three types of risk involved in investing in smart infrastructures compared with traditional infrastructures: construction risk; the impact of operational failures; and confidence in outcomes.

Construction Risk

At a discussion in March of the financing of future city initiatives held within the Lord Mayor of the City of London’s “Tommorrow’s Cities” programme, Daniel Wong, Head of Infrastructure and Real Estate for Macquarie Capital Europe, said that only a “tiny fraction” – a few percent – of the investable resources of the pension and sovereign wealth funds often referred to as the “wall of money” seeking profitable long-term investment opportunities in infrastructure were available to invest in infrastructure projects that carry “construction risk” – the risk of financial loss or cost overruns during construction.

For conventional infrastructure, construction risk is relatively well understood. At the Tomorrow’s Cities event, Jason Robinson, Bechtel’s General Manager for Urban Development, said that the construction sector was well able to manage that risk on behalf of investors. There are exceptions – such as the delays, cost increases and reduction in scale of Edinburgh’s new tram system – but they are rare.

So are we similarly well placed to manage the additional “construction risk” created when we add new technology to infrastructure projects?

Unfortunately, research carried out in 2013 by the Standish Group on behalf of Computerworld suggests not. Standish Group used data describing 3,555 IT projects between 2003 and 2012 that had labour costs of at least $10 million, and found that only 6.4% were wholly successful. 52% were delivered, but cost more than expected, took longer than expected, or failed to deliver everything that was expected of them. The rest – 41.4% – either failed completely or had to be stopped and re-started from scratch. Anecdotally, we are familiar with the press coverage of high profile examples of IT projects that do not succeed.

We should not be surprised that it is so challenging to deliver IT projects. They are almost always driven by requirements that represent an aspiration to change the way that an organisation or system works: such requirements are inevitably uncertain and often change as projects proceed. In today’s interconnected world, many IT projects involve the integration of several existing IT systems operated by different organisations: most of those systems will not have been designed to support integration. And because technology changes so quickly, many projects use technologies that are new to the teams delivering them. All of these things will usually be true for the technology solutions required for Smart City projects.

By analogy, then, an IT project often feels like an exercise in building an ambitiously new style of building, using new materials whose weight, strength and stiffness isn’t wholly certain, and standing on a mixture of sand, gravel and wetland. It is not surprising that only 6.4% deliver everything they intend to, on time and on budget – though it is also disappointing that as many as 41.4% fail so completely.

However, the real insight is that the characteristics of uncertainty, risk, timescales and governance for IT projects are very different from construction and infrastructure projects. All of these issues can be managed; but they are managed in very different ways. Consequently, it will take time and experience for the cultures of IT and construction to reconcile their approaches to risk and project management, and consequently to present a confident joint approach to investors.

The implementation of Smart Cities IT solutions on Cloud Computing platforms  by their providers mitigates this risk to an extent by “pre-fabricating” these components of smart infrastructure. But there is still risk associated with the integration of these solutions with physical infrastructure and engineering systems. As we gain further experience of carrying out that integration, IT vendors, investors, construction companies and their customers will collectively increase their confidence in managing this risk, unlocking investment at greater scale.

Operational Risk

We are all familiar with IT systems failing.

Our laptops, notebooks and tablets crash, and we lose work as a consequence. Our television set-top boxes reboot themselves midway through recording programmes. Websites become unresponsive or lose data from our shopping carts.

But when failures occur in IT systems that monitor and control physical systems such as cars, trains and traffic lights, the consequences could be severe: damage to property, injury; and death. Organisations that invest in and operate infrastructure are conscious of these risks, and balance them against the potential benefits of new technologies when deciding whether to use them.

The real-world risks of technology failure are already becoming more severe as all of us adopt consumer technologies such as smartphones and social media into every aspect of our lives (as the driver who followed his satellite navigation system off the roads of Paris onto the pavement, and then all the way down the steps into the Paris Metro, discovered).

The noted urbanist Jane Jacobs defined cities by their ability to provide privacy and safety amongst citizens who are usually strangers to each other; and her thinking is still regarded today by many urbanists as the basis of our understanding of cities. As digital technology becomes more pervasive in city systems, it is vital that we evolve the policies that govern digital privacy to ensure that those systems continue to support our lives, communities and businesses successfully.

Google’s careful exploration of self-driving cars in partnership with driver licensing organisations is an example of that process working well; the discovery of a suspected 3D-printing gun factory in Manchester last year is an example of it working poorly.

These issues are already affecting the technologies involved in Smart Cities solutions. An Argentinian researcher recently demonstrated that traffic sensors used around the world could be hacked into and caused to create misleading information. At the time of installation it was assumed that there would never be a motivation to hack into them and so they were configured with insufficient security. We will have to ensure that future deployments are much more secure.

Conversely, we routinely trust automated technology in many aspects of our lives – the automatic pilots that land the planes we fly in, and the anit-lock braking systems that slow and stop our cars far more effectively than we are able to ourselves.

If we are to build the same level of trust and confidence in Smart City solutions, we need to be open and honest about their risks as well as their benefits; and clear how we are addressing them.

Outcomes Risk

Smart infrastructures such as Stockholm’s road-use charging scheme and London’s congestion charge were constructed in the knowledge that they would be financially sustainable, and with the belief that they would create economic and environmental benefits. Subsequent studies have shown that they did achieve those benefits, but data to predict them confidently in advance did not exist because they were amongst the first of their kind in the world.

The benefits of “Smart” schemes such as road-use charging and smart metering cannot be calculated deterministically in advance because they depend on citizens changing their behaviour – deciding to ride a bus rather than to drive a car; or deciding to use dishwashers and washing machines overnight rather than during the day.

There are many examples of Smart Cities projects that have successfully used technology to encourage behaviour change. In a smart water meter project in Dubuque, for example, households were given information that told them whether their domestic appliances were being used efficiently, and alerted to any leaks in their supply of water. To a certain extent, households acted on this information to improve the efficiency of their water usage. But a control group who were also given a “green points” score telling them how their water conservation compared to that of their near neighbours were found to be twice as likely to take action to improve their efficiency.

However, these techniques are notoriously difficult to apply successfully. A recycling scheme that adopted a similar approach found instead that it lowered recycling rates across the community: households who learned that they were putting more effort into recycling than their neighbours asked themselves “if my neighbours aren’t contributing to this initiative, then why should I?”

The financial vehicles that enable investment in infrastructure and property are either government-backed instruments that reward economic and social outcomes such as reductions in carbon footprint or the creation of jobs ; or market-based instruments  based on the creation of direct financial returns.

So are we able to predict those outcomes confidently enough to enable investment in Smart Cities solutions?

I put that question to the debating panel at the Tomorrow’s Cities meeting. In particular, I asked whether investors would be willing to purchase bonds in smart metering infrastructures with a rate of return dependent on the success of those infrastructures in encouraging consumers to  reduce their use of water and energy.

The response was a clear “no”. The application of those technologies and their effectiveness in reducing the use of water and electricity by families and businesses is too uncertain for such investment vehicles to be used.

Smart Cities solutions are not straightforward engineering solutions such as electric vehicles whose cost, efficiency and environmental impacts can be calculated in a deterministic way. They are complex socio-technical systems whose outcomes are emergent and uncertain.

Our ability to predict their performance and impact will certainly improve as more are deployed and analysed, and as University researchers, politicians, journalists and the public assess them. As that happens, investors will be more willing to fund them; or, with government support, to create new financial vehicles that reward investment in initiatives that use smart technology to create social, environmental and economic improvements – just as the World Bank’s Green Bonds, launched in 2008, support environmental schemes today.

Evidence and Leadership

The evidence base need to support new investment vehicles is already being created. In Canada, for example, a collaboration between Canadian insurers and cities has developed a set of tools to create a common understanding of the financial risk created by the effects of climate change on the resilience of city infrastructures.

More internationally, the “Little Rock Accord” between the Madrid Club of former national Presidents and Prime Ministers and the P80 group of pension funds agreed to create a task force to increase the degree to which pension and sovereign wealth funds invest in the deployment of technology to address climate change issues, shortages in resources such as energy, water and food, and sustainable, resilient growth. My colleague the economist Mary Keeling has been working for IBM’s Institute for Business Value to more clearly analyse and express the benefits of Smart approaches – in water management and transportation, for example. And Peter Head’s Ecological Sequestration Trust and Robert Bishop’s International Centre for Earth Simulation are both pooling international data and expertise to create models that explore how more sustainable cities and societies might work.

But the Smart City programmes which courageously drive the field forward will not always be those that demand a complete and detailed cost/benefit analysis in advance. Writing in “The Plundered Planet”, the economist Paul Collier asserts that any proposed infrastructure of reasonable novelty and significant scale is effectively so unique – especially when considered in its geographic, political, social and economic context – that an accurate cost/benefit case simply cannot be constructed.

Instead, initiatives such as London’s congestion charge and bicycle hire scheme, Sunderland’s City Cloud and Bogota’s bikeways and parks were created by courageous leaders with a passionate belief that they could make their cities better. As more of those leaders come to trust technology and the people who deliver it, their passion will be another force behind the adoption of technology in city systems and infrastructure.

What’s the risk of not investing in a Smarter City?

For at least the last 50 years, we have been observing that life is speeding up and becoming more complicated. In his 1964 work “Notes on the Synthesis of Form“, the town planner Christopher Alexander wrote:

“At the same time that the problems increase in quantity, complexity and difficulty, they also change faster than ever before. New materials are developed all the time, social patterns alter quickly, the culture itself is changing faster than it has ever changed before … To match the growing complexity of problems, there is a growing body of information and specialist experience … [but] not only is the quantity of information itself beyond the reach of single designers, but the various specialists who retail it are narrow and unfamiliar with the form-makers’ peculiar problems.”

(Alexander’s 1977 work “A Pattern Language: Towns, Buildings, Construction” is one of the most widely read books on urban design; it was also an enormous influence on the development of the computer software industry).

The physicist Geoffrey West has shown that this process is alive and well in cities today. As the world’s cities grow, life in them speeds up, and they create ideas and wealth more rapidly, leading to further growth. West has observed that, in a world with constrained resources, this process will lead to a catastrophic failure when demand for fresh water, food and energy outstrips supply – unless we change that process, and change the way that we consume resources in order to create rewarding lives for ourselves.

There are two sides to that challenge: changing what we value; and changing how we create what we value from the resources around us.

The Transition movement, started by Rob Hopkins in Totnes in 2006, is tackling both parts of that challenge. “Transition Towns” are communities who have decided to act collectively to transition to a way of life which is less resource-intensive, and to value the characteristics of such lifestyles in their own right – where possible trading regionally, recycling and re-using materials and producing and consuming food locally.

The movement does not advocate isolation from the global industrial economy, but it does advocate that local, alternative products and services in some cases can be more sustainable than mass-produced commodities; that the process of producing them can be its own reward; and that acting at community level is for many people the most effective way to contribute to sustainability. From local currencies, to food-trading networks to community energy schemes, many “Smart” initiatives have emerged from the transition movement.

We will need the ideas and philosophy of Transition to create sustainable cities and communities – and without them we will fail. But those ideas alone will not create a sustainable world. With current technologies, for example, one hectare of highly fertile, intensively farmed land can feed 10 people. Birmingham, my home city, has an area of 60,000 hectares of relatively infertile land, most of which is not available for farming at all; and a population of around 1 million. Those numbers don’t add up to food self-sufficiency. And Birmingham is a very low-density city – between one-half and one-tenth as dense as the growing megacities of Asia and South America.

Cities depend on vast infrastructures and supply-chains, and they create complex networks of transactions supported by transportation and communications. Community initiatives will adapt these infrastructures to create local value in more sustainable, resilient ways, and by doing so will reduce demand. But they will not affect the underlying efficiency of the systems themselves. And I do not personally believe that in a world of 7 billion people in which resources and opportunity are distributed extremely unevenly that community initiatives alone will reduce demand significantly enough to achieve sustainability.

We cannot simply scale these systems up as the world’s population grows to 9 billion by 2050, we need to change the way they work. That means changing the technology they use, or changing the way they use technology. We need to make them smarter.

No-one wants top-down, technology-driven cities. They’d be dumb, not smart.

("Visionary City" by William Robinson Leigh)

(William Robinson Leigh’s 1908 painting “Visionary City” envisaged future cities constructed from mile-long buildings of hundreds of storeys connected by gas-lit skyways for trams, pedestrians and horse-drawn carriages. A century later we’re starting to realise not only that developments in transport and power technology have eclipsed Leigh’s vision, but that we don’t want to live in cities constructed from buildings on this scale.)

But “bottom up” is not enough; in order to succeed at scale, grass-roots innovation and localism need support from a new environment of policy, finance, infrastructure and technology.

I took part in a panel discussion last week with Leo Johnson, co-author of “Turnaround Challenge: Business and the City of the Future” (and, coincidentally, the brother of London’s Mayor, Boris Johnson). Leo argued in an impassioned speech that we should avoid overly deterministic “top-down” approaches to developing sustainable cities, and should instead encourage “bottom-up” innovation. His points echoed some of the criticisms levelled at parts of the Smart Cities movement by writers such as Adam Greenfield and Richard Sennett.

But these are arguments against a proposition that I simply don’t think anyone is advocating today.

In all of my contacts across the world, in technology, government and urban design, I don’t know anyone who thinks it would be “smart” for cities to be run wholly by technological systems; who believes that digital data can provide “perfect knowledge” about city systems; or who thinks that cities built and run entirely by deterministic plans driven from the top down would be healthy, vibrant places to live (or indeed are possible at all).

Smart cities are not about putting machines in control, and they are not about imposing an idealistic, corporate way of life. They are simply about harnessing the ever-advancing capabilities of technology in our efforts to create a more sustainable, equitable, resilient world in the cities in which more and more of us are living.

The ultimate purpose of cities is to enable the people who live and work in them to lead safe and rewarding lives with their families. The raw material from which the life of cities is built is therefore small-scale – it is the activity of individual people in their personal and family life or going about their work. Consequently, there is an enormous focus in smart cities and smart urbanism on “bottom-up” thinking : how can we enable private businesses, community innovators and citizen-led initiatives to be successful, and to create sustainable wealth and social value? If the opportunities to do that are widely available, then cities as a whole will be more successful, and, when economic or climate events affect their circumstances, they will be more adaptable and resilient.

But let’s be frank: that’s an awfully big “if”.

There’s nothing new about “bottom-up” creativity – that’s simply what people do as they get on with life, using whatever resources are available to them to craft a living, support their families and build successful businesses. But the truth is that we are not very good at all at creating environments in which everybody has an equal chance of succeeding in those efforts.

For bottom-up creativity to be broadly successful, citizens, communities and businesses must be able to adapt the city infrastructures that provide food, water, energy, transport and resources to serve their specific needs and opportunities. Those infrastructures are vast – they support 3 billion urban lives worldwide today, and will need to scale to support 3 billion more by 2050. Communities and neighbourhoods with persistently low levels of economic activity and social mobility – those most in need of innovative answers to their challenges – are often those who have the least access to those infrastructures, and whose issues can include poor schools, disconnection from transport networks, exclusion from mainstream financial systems, fuel poverty and so on. Those problems will not solve themselves: we will only adapt city infrastructures and institutions to serve these communities better through significant effort from the businesses and governments that control and govern them.

(When planning policy and other regulations allow, urban farms can adapt the physical infrastructure of cities to create new sources of food. A similar combination of policy innovation and grass-roots creativity could enable similarly creative uses of digital infrastructure and information in cities. Photo by ToadLickr)

From the governance of cities, to the policies that affect investment, to the oversight, administration and operation of city infrastructures – these processes work top-down; and in order for us to rely on “bottom-up” creativity improving cities for all of their citizens, we must adapt and improve them to better support that creativity.

Technology plays three roles in this context. Firstly, smartphones, tablets, 3D printers and social media are examples of new consumer and citizen tools that we could barely imagine as recently as a decade ago. They make immense power available to bottom-up, small-scale activity and local innovations, and have resulted in the emergence of significant economic trends such as the “sharing economy” of business models based on peer-to-peer transactions.

Secondly, though, many of those technologies depend fundamentally on the availability of connectivity infrastructure; and that infrastructure is not available everywhere. Some 18% of adults in the UK have never been online; and children today without access to the internet at home and in school are at an enormous disadvantage. Most cities and countries have not yet addressed this challenge. Private sector network providers will not deploy connectivity in areas which are insufficiently economically active for them to make a profit, and Government funding is not yet sufficient to close the gap. This challenge has not and will not be addressed by bottom-up creativity; it requires top-down legislation and investment.

Thirdly, technology can help to open up the operations and infrastructures of big institutions and companies to local innovation – from the provision of “open data” and API interfaces that allow these systems to be adapted to new uses; to the use of technology to measure and trace the social and environmental impact of goods and services in order to inform consumer choice so that it can become a lever to improve the impact of the vast supply chains that supply cities. Unilever and Tesco are just two examples of businesses pursuing this business strategy.

These are the roles of technology that enable a meeting or balance between top-down and bottom-up forces in cities – a balance that Anthony Townsend, author of “Smart Cities: Big Data, Civic Hackers, and the Quest for a New Utopia” has advocated in our online exchanges.

Smart cities is not a prescriptive, top-down, corporate movement. The perception that it was arose because a handful of early and highly visible examples such as Masdar and Songdo were new, large-scale developments financed by strong economic growth in emerging markets; or because some of the rapid urbanisation taking place today is in countries with strongly hierarchical governance. These examples also gave emphasis to the importance of efficiently and intelligently operating large-scale city infrastructures – without which we’ll never sustainably and resiliently support the 6 billion city inhabitants predicted by the United Nations’ World Urbanisation Prospects report by 2050.

But we must give equal recognition to the vast amount of bottom-up creativity that took place throughout this period; that continues today; and which has exploited technology in strikingly innovative ways.

The “open data” movement has become a force for transparency in government and for addressing social and environmental issues. “Civic hacking” communities have sprung up around the world, using this data to create novel new public services. Many of my colleagues have contributed to that movement, either representing IBM, or simply as personal contributions to the cities in which they live – as have the employees of many other businesses. And community initiatives everywhere now routinely exploit technologies such as social media and crowdfunding; or co-create schemes to apply commercial technologies for their own purposes. For example, in the village of Chale on the Isle of Wight, a community with significant levels of fuel poverty worked together to use smart energy meters to reduce their energy bills by up to 50%.

There are two serious challenges in how we apply these ideas more broadly that demand debate:

And:

The Economist magazine reminded us of the importance of those questions in a recent article describing the enormous investments made in public institutions in the past in order to distribute the benefits of the Industrial Revolution to society at large rather than concentrate them on behalf of business owners and the professional classes.

We have only partially been successful in those efforts. As one measure, it’s common for life expectancy to vary by around 20 years between the poorest and richest parts of the same city in the UK. Scandinavian cities do not show that disparity – their culture and system of taxation, benefits and collective insurance create a more equal opportunity to live. In the UK, the US and other societies that emphasise greater retention of private wealth and the distribution of opportunity through flexible market economies, how can we better approach Scandinavia’s level of equality?

These questions are much more important than perpetuating an adversarial debate between “top down” and “bottom up” thinking. No-one wants top-down, technology driven cities. They’d be dumb, not smart. And no-one believes that digital data can provide “perfect knowledge” – we all understand that perfect knowledge is neither possible nor desirable.

Digital data and technology do much more realistic and exciting things. They allow us to uncover the hidden opportunity to transact locally with people and businesses in our community. They reveal patterns in the messy complexity of social, economic, physical and environmental systems that help us to look ahead to likely outcomes, take proactive measures and do more with less. And they make it possible for us to connect to people around the world who we’ve never met but with whom we share an interest or can create a new opportunity.

A smart city creates an environment in which technology, infrastructure, policies and culture make people safe, and provide the resources and opportunities they need – including better access to technology and information – to create safer and more rewarding lives.

That’s not top-down or bottom-up. It’s common sense. Let’s stop arguing and start applying it.

Creating successful Smart Cities in 2014 will be an economic, financial and political challenge, not an engineering accomplishment

Why insurers, pension funds and politics will be more important to Smart Cities in 2014 than “Living Labs” or technology.

I hope that 2014 will be the year in which we see widespread and large-scale investments in future city technology infrastructures that enable sustainable, equitably distributed economic and social growth. The truth is that we are still in the very early stages of that process.

In 2012 I spoke with a Director at a financial consultancy who’d performed a survey of European Smart City initiatives. She confirmed something that I suspected at the time: that the great majority of Smart City initiatives up to that point in the mature markets of Europe and North America had been financed by research funding, rather than on a commercial basis.

Four trends characterised the subsequent development of Smart Cities throughout 2013. Firstly, emerging markets continued to invest in supporting the rapid urbanisation they are experiencing; and businesses, Universities and national governments in developed nations recognised the commercial opportunity for them to supply that market with “Smart” solutions.

Secondly, it remains the case that the path to growth for undeveloped nations is still extremely slow and complex; so whilst there is private sector and national government interest in investing in those nations – IBM’s new Research centre in Nairobi being an example – many “smart” initiatives are carried out at small scale by local innovators, the third sector or development agencies.

In Europe and North America, a third trend was the continuing announcement of investments by the European Union and national governments in the applied research and innovation agenda in cities – such as the EU’s Horizon 2020 programme, for example.

Perhaps most importantly, though, the final trend was for cities in Europe and North America to start to make investments in the underlying technology platforms for Smart Cities from their own operational budgets, on the basis of their ability to deliver cost savings or improvements in outcomes. For example, some cities are replacing traditional parking management and enforcement services with “smart parking” schemes that are reducing congestion and pollution whilst paying for themselves through improved revenues. Others are investing their allocation of central government infrastructure funds in Smart solutions – such as Cambridge, Ontario’s use of the Canadian government’s Gas Tax Fund to invest in a sensor network and analytics infrastructure to manage the city’s physical assets intelligently.

This trend to create business cases for investment from normal operating budgets or infrastructure investment programmes is important not only because it shows that these cities are developing the business models to support investment in “Smart” solutions locally, where the finances associated with rapid economic growth and urbanisation are not present; but also because (at the risk of simplifying a challenging and complex issue) some of those business models might serve as a template for self-sustainable adoption in less developed nations.

Whilst the idea of a “Smart City” has been capturing the imagination for several years now, the reality is that many cities are still deciding what that idea might mean for them. For example, London’s “Smart London Board” published it’s Smart London plan in December, following Birmingham’s Smart City Commission report earlier in the year. And most cities who are considering such plans now or who have recently published them are still determining how to put the finance in place to carry them out.

Will “Living Labs” be the death of Smart Cities?

A concept that I see in many such plans that is intended to assist in securing finance, but that I think risks being a distraction from addressing it properly, is the “Living Lab”. 

Living labs emerged as a set of best practises for carrying out applied research into consumer or citizen services with a focus on collaborative, user-centred design and co-creation. Many cities are now seeking to win funding for their Smarter Cities initiatives by offering themselves as “Living Labs” in which consortia constructing proposals for applied research funding can carry out their activities.

The issue is not that Living Lab’s aren’t a good idea – on the contrary, they are undoubtably a very good set of prescriptions for carrying out such research and design successfully. The problem is that there are now so many cities intending to follow this approach that it no longer makes them stand out as particularly effective environments in which to perform research.

Research programmes will continue to fund the first deployments of new Smart City ideas and technology; but competition for those funds will be fierce. Cities, universities and companies that bid for them will invest many months – often more than a year – in developing their proposals; and in competitions, most entrants do not win.

The real need in cities is for the development and regeneration of infrastructure. There are certainly research topics concerning infrastructure that will attract funding from national and international government bodies; but those funds will not support the rollout of citywide infrastructure to every city in every country.

(Birmingham's new city-centre tram)

(Birmingham’s new city-centre tram is an infrastructure investment that will contribute to the same objectives as the city’s Smart City vision.)

The big questions for European and American cities in 2014 are then:

Will they continue to invest resources competing for applied research and innovation funding, limiting the speed at which the widespread deployment of new infrastructure will take place?

Or will they focus on developing independently viable business cases for investment in the infrastructure to support their
Smarter City visions?

There’s a real need for clarity about these issues. Whilst the enormous level of innovation funding being made into smart buildings, smart transport and smart cities by the EU Horizon 2020 programme and national equivalents such as the UK’s Technology Strategy Board will stimulate the field and fund important demonstration projects that deliver real value, these bodies will not pay for all of our cities to become Smarter.

The same is true for the research investments made by commercial organisations including technology companies such as IBM. Commercial research investments fund the first attempts to apply technology to solve problems or achieve objectives in new ways; those that succeed are subsequently deployed elsewhere on a commercial basis.

The risk is that in seeking investment from research programmes, we become distracted from addressing the real challenge: how to make the case for private sector investment in new technology infrastructures based on the economic and social improvements they will enable; or on the direct financial returns that they will generateIn the UK, for example, a specialist body in Government, Infrastructure UK, coordinates private sector funding for public infrastructure. And if we can persuade property developers of the value of “Smart” technologies, then cities could benefit from the enormous investments made in property every year that currently don’t result in the deployment of technology – the British Property Federation, for example, estimate that £14 billion is invested in the development of new space in the UK each year.

This is an opportunity we should treat with urgency. Whilst public sector finances are under immense pressure, the vast wealth held in private investment funds is seeking new opportunities following the poor returns that many traditional forms of investment have yielded over the last few years. There is a lot of work to do between the stakeholders in cities, government and finance before these investment sources can be exploited by Smart Cities – not least in agreeing reasonable expectations for how the risks and returns will be measured and shared. But I personally believe that until we do so, we will not be able to properly finance the development of our next generation of cities.

As Jane Jacobs wrote in her seminal 1961 work “The Death and Life of Great American Cities“:

“Private investment shapes cities, but social ideas (and laws) shape private investment. First comes the image of what we want, then the machinery is adapted to turn out that image. The financial machinery has been adjusted to create anti-city images because, and only because, we as a society thought this would be good for us. If and when we think that lively, diversified city, capable of continual, close-grained improvement and change, is desirable, then we will adjust the financial machinery to get that.”

Overcoming these challenges won’t be easy, and doing so will require each of the various stakeholder organisations facing them to take bold steps this year.

Local Government

Whilst their finances throughout the developed world have been under severe pressure for a long time now, local government bodies are still responsible for procuring a significant volume of goods and services. Smart Cities will only become a reality when local authority visions for the future are reflected in procurement practises and scoring criteria for contracts issued today. It’s only very recently that procurements for contracts to build, update and manage physical infrastructures such as roads and pavements have been based on outcomes such as minimising congestion or increasing the overall quality of performance throughout the lifetime of the asset within the contract value, rather than on securing the maximum volume of concrete (or number of traffic wardens).

Outcomes-based procurements are challenging to be sure, both for the purchaser and the provider; especially so when they are for such new solutions. But service and infrastructure providers will only be motivated to propose and deliver innovative, smart solutions when they’re rewarded for doing so.

Local authorities can also exploit indirect mechanisms such as planning and development frameworks. I worked last year with one authority which asked how its planning framework should evolve in order to promote the development of a “Smart City”, and published a set of 23 “Design principles for a Smarter City” as a result. They require that investments in property also deliver technology infrastructures such as wi-fi, broadband, open-data, and multi-channel self-service access.

(An analysis based on GPS data from mobile phones of end-to-end journeys undertaken by users of Abidjan’s bus services. By comparing existing bus routes to end-to-end journey requirements, the analysis identified four new bus routes and led to changes in many others. As a result, 22 routes now show increased ridership, and city-wide journey times have decreased by 10%. The techniques and technologies behind the project build on those developed for projects in Dubuque, Istanbul and Dublin.)

Private Sector

The technology companies associated with Smart Cities have sometimes been criticised for focussing too much on the technology that can be applied to city infrastructures, and not enough on the improvements to people’s work and lives that technology can enable, or on the business cases for investing in it.

To make the business case clearer, my colleague the economist Mary Keeling has been working for IBM’s Institute for Business Value to more clearly analyse and express the benefits of Smart approaches – in water management and transportation, for example. And I’ll be contributing along with representatives from many of the other companies that provide technology and infrastructure for Smart Cities to the TSB’s Future Cities Catapult’s finance initiative.

But we also need to respect the principles of Living Labs and the experience of urban designers – not least the writing of Jane Jacobs – which reflect that our starting point for thinking about Smart Cities should be the everyday lives and experiences of individual citizens in their family lives; at work; and moving through cities. In one sense, this is business as usual in the technology industry – “user-centered design“, “use cases” and “user stories” have been at the heart of software development since the 1980s. So one of our challenges is simply to communicate that approach more clearly within our descriptions of Smart Cities. This is a topic I’ve written about in many articles on this blog that you can find described in “7 Steps to a Smarter City“; and that I tried to address in IBM’s new Smarter Cities video.

The other challenge is for technology companies to become more familiar and expert in the disciplines associated with good quality urban design – town planning, architecture, social science and the psychology of human behaviour, for example. This is one of the reasons why IBM started the “Smarter Cities Challenge” programme through which we have donated our technology expertise to 100 cities worldwide to help them address the opportunities and challenges they face; and in so doing become more familiar with their very varied cultures, economies, issues and capabilities. It’s also why I joined the Academy of Urbanism, along with representatives of several other technology companies.

We also need to embrace the “Smart Urbanism” thinking exemplified by Kelvin Campbell. Kelvin’s “Massive / Small” approach is intended to design large-scale urban infrastructures that encourage and support “massive” amounts of “small-scale” innovation. I think that’s an extremely powerful idea that we should embrace in Smarter Cities; and that translates directly to the practise of providing open-standard, public interfaces to city technology infrastructures – open data feeds and APIs (“Application Programming Interfaces”), for example – that not only reduce the risk that city systems become “locked-in” to any proprietary provider; but that also open up the power of large scale technology systems and “big data” sources so that local businesses, innovators and communities are able to adapt public infrastructures to their own needs. I think of these interfaces as creating an “innovation boundary” between a city’s infrastructure and its stakeholders.

Central Government

In most countries in the developed world – i.e. those which are not being driven by rapid urbanisation today because they urbanised during the Industrial Revolution – the majority of Smart City initiatives that have momentum are driven by Mayors convening city stakeholders and institutions to co-create, finance and deliver those initiatives. Correspondingly, in countries without strong mayoral systems – such as the UK – progress can be slower. Worryingly, Centre for Cities’ recent Outlook 2014 report pointed out that only 17% of funding for UK cities comes from locally administered taxation, as opposed to the OECD average of 55%.

To risk stating the obvious, every city is different, and different in very many important ways, from its geographical situation to its linkage to national and international transport infrastructure; from its economic and business capabilities to the skills and wealth of its population; from its social challenges and degree of social mobility to its culture and heritage. Successful Smart City initiatives are specific, not generic; and the greater degree of autonomy that cities are allowed in setting strategy and securing financing, the greater their capability to pursue those initiatives. Programmes such as “City Deals” and the recent reforms resulting from Lord Heseltine’s “No Stone Unturned” report are examples of progress towards greater autonomy for the UK’s cities, but they are not enough.

Central government will always have a significant role in funding the infrastructures that cities rely on, of course; whether that’s national infrastructures that connect cities (such as the planned “HS2” high-speed train network in the UK, or Australia’s national deployment of broadband internet connectivity), or specific infrastructures within cities, such as Birmingham’s new city-centre tram. And so just as local governments should consider how they can use procurement practises and planning frameworks to encourage investments in property and infrastructure that deliver “Smart” solutions, so central government should consider how the funding programmes that it administers can contribute to cities’ “Smart” objectives.

Financial Services

If the challenge is to unlock investment in new assets and outcomes, then we should turn to banks, insurers and investors to help us shape the new financial vehicles that we will require to do so. In Canada, for example, a collaboration between Canadian insurers and cities has developed a set of tools to create a common understanding of the financial risk created by the effects of climate change on the resilience of city infrastructures. These tools are the first step towards creating investment and insurance models for city infrastructures that will be exposed to new levels of risk; that will need to exhibit new levels of resilience; and that in turn may require Smart solutions to achieve them.

More internationally, the “Little Rock Accord” between the Madrid Club of former national Presidents and Prime Ministers and the P80 group of pension funds agreed to create a task force to increase the degree to which pension and sovereign wealth funds invest in the deployment of technology to address climate change issues, shortages in resources such as energy, water and food, and sustainable, resilient growth. And more locally, I’m proud to note that my home city of Birmingham is a pioneer in this area through the Birmingham Energy Savers project, financed through a mixture of prudential borrowing and private sector investment.

It has taken us too long to get to this point, but I’m encouraged that several initiatives are now convening discussions between the traditionally understood stakeholders in Smart Cities – local authorities, technology companies, universities and built-environment companies – and the financial sector. For example, in addition to the Future Cities Catapult’s financing programme, on March 13th, I’ll be speaking at an event organised by the Lord Mayor of the City of London to encourage the City’s financial institutions and UK city authorities to undertake a similar collaboration to develop new financing models for future city infrastructures.

Are Smarter Cities a “middle out” economic intervention?

In his 2011 Presidential Campaign speech Barack Obama promised an economic strategy based on “middle-out” economics – the philosophy that equitable, sustainable growth is driven by the spending power of middle class consumers, as an alternative to “trickle-down” economics – the philosophy that growth is best created when very rich “wealth-creators” are free to become as successful as possible.

As this analysis in “The Atlantic” shows, job creation does depend on the investments of the wealthiest; but also on the spending power of the masses; and on a lot of very hard work making sure that a reasonable portion of the profits created by both of those activities are used to invest in making skills, education and opportunity available to all. The Economist magazine made the same point in a recent article by reminding us of the enormous investments made into public institutions in the past in order to distribute the benefits of the Industrial Revolution to society at large rather than concentrate them on behalf of business owners and the professional classes; though with only partial success.

 Those ideas are reflected in what it takes to craft an investment in a technology-enabled Smart City initiative that successfully creates social and economic improvements in a city.

Whilst a huge number of effective “Smart” ideas will be created “bottom-up” by innovators and social entrepreneurs intimately familiar with specific local communities and context, those ideas will not succeed as well or rapidly as we need them to without significant investment in new infrastructures – such as wi-fi, broadband and realtime open data – that are deployed everywhere, not just in the most economically active areas of cities that reward commercial investment most quickly. Accessibility to these infrastructures creates the “innovation boundary” between city institutions and infrastructures, and local innovators and communities.

This is not an abstract concept; it is an idea that some cities are making very real today. For example, the “Dublinked” information-sharing partnership between Dublin County Council, three surrounding County Councils and the National University of Ireland now makes available 3,000 city datasets as “open data” – including a realtime feed showing the location of buses in the city. That’s a resource that local innovators can use to create their own new applications and services. Similarly, in Birmingham the “West Midlands Open Data Forum” has emerged as a community in which city local businesses and innovators can negotiate access to data held by city institutions and service providers.

(David Willets, MP, Minister for Universities and Science, launches the UK Government’s Smart Cities Forum)

At launch of the UK Government’s “Smart Cities Forum” last year, I remarked that we were not inviting key stakeholders to the Smarter Cities debate – specifically, banks, investors, insurers and entrepreneurs. Some of the initiatives I’ve described in this article are starting to address that omission; and to recognise that the most significant challenges are to do with finance, politics, social issues and economics, not engineering and technology.

And those are challenges that all of us should focus on. No-one is going to pay for our cities to become Smarter, more successful, more sustainable and fairer: we will have to figure out how to pay for  those things ourselves.

Information and choice: nine reasons our future is in the balance

(The Bandra pedestrian skywalk in Mumbai, photo taken from the Collaborative Research Initiative Trust‘s study of Mumbai, “Being Nicely Messy“, produced for the 2012 Audi Urban Futures awards)

The 19th and 20th centuries saw the flowering and maturation of the Industrial Revolution and the creation of the modern world. Standards of living worldwide increased dramatically as a consequence – though so did inequality.

The 21st century is already proving to be different. We are reaching the limits of supply of the natural resources and cheap energy that supported the last two centuries of development; and are starting to widely exploit the most powerful man-made resource in history: digital information.

Our current situation isn’t simply an evolution of the trends of the previous two centuries; nine “tipping points” in economics, society, technology and the environment indicate that our future will be fundamentally different to the past, not just different by degree.

Three of those tipping points represent changes that are happening as the ultimate consequences of the Industrial Revolution and the economic globalisation and population growth it created; three of them are the reasons I think it’s accurate to characterise the changes we see today as an Information Revolution; and the remaining three represent challenges for us to face in the future.

The difficulty faced in addressing those challenges internationally through global governance institutions is illustrated by the current status of world trade deal and climate change negotiations; but our ability to respond to them is not limited to national and international governments. It is in the hands of businesses, communities and each of us as individuals as new business models emerge.

The structure of the economy is changing

In 2012, the Collaborative Research Initiatives Trust were commissioned by the Audi Urban Futures Awards to develop a vision for the future of work and life in Mumbai. In the introduction to their report, “Being Nicely Messy“, they cite a set of statistics describing Mumbai’s development that nicely illustrate the changing nature of the city:

“While the population in Mumbai grew by 25% between 1991 and 2010, the number of people travelling by trains during the same years increased by 66% and the number of vehicles grew by 181%. At the same time, the number of enterprises in the city increased by 56%.

All of this indicates a restructuring of the economy, where the nature of work and movement has changed.”

(From “Being Nicely Messy“, 2011, Collaborative Research Initiatives Trust)

Following CRIT’s inspiration, over the last year I’ve been struck by several similar but more widely applicable sets of data that, taken together, indicate that a similar restructuring is taking place across the world.

The twilight of the Industrial Revolution

Tipping point 1: the slowing of economic growth

According to the respected investor Jeremy Grantham, Economic growth has slowed systemically and permanently. He states that: “Resource costs have been rising, conservatively, at 7% a year since 2000 … in a world growing at under 4% and [in the] developed world at under 1.5%”

Grantham’s analysis is that the rapid economic growth of the last century was a historical anomaly driven by the productivity improvements made possible through the Industrial Revolution; and before that revolution reached such a scale as to create global competition for resources and energy. Property and technology bubbles extended that growth into the early 21st Century, but it has now reduced to much more modest levels where Grantham expects it to remain. The economist Tyler Cowan came to similar conclusions in his 2011 book, “The Great Stagnation“.

This analysis was supported by the property developers I met at a recent conference in Birmingham. They told me that indicators in their market today are the most positive they have been since the start of the 1980s property boom; but none of them expect that boom to be repeated. The market is far more cautious concerning medium and long-term prospects for growth.

We have passed permanently into an era of more modest economic growth than we have become accustomed to; or at very least into an era whereby we need to restructure the relationship between economic growth and the consumption of resources and energy in ways that we have not yet determined before higher growth does return. We have passed a tipping point; the world has changed.

(Growth in the world’s urban population as reported by “World Urbanization Prospects”, 2007 Revision, Department of Economic and Social Affairs, United Nations)

Tipping point 2: urbanisation and the industrialisation of food supply 

As has been widely quoted in recent years, more than half the world’s population has lived in cities since 2010 according to the United Nations Department of Economic and Social Affairs. That percentage is expected to increase to 70% by 2050.

The implications of those facts concern not just where we live, but the nature of the economy. Cities became possible when we industrialised the production and distribution of food, rather than providing it for ourselves on a subsistence basis; or producing it in collaboration with our neighbours. For this reason, many developing nations still undergoing urbanisation and industrialisation – such as Tanzania, Turkmenistan and Tajikstan – still formally define cities by criteria including “the pre-dominance of non-agricultural workers and their families” (as referenced in the United Nations’ “World Urbanization Prospects” 2007 Revision).

So for the first time more than half the world’s population now lives in cities; and is provided with food by industrial supply chains rather than by families or neighbours. We have passed a tipping point; the world has changed.

Tipping point 3: the frequency and impact of extreme weather conditions

As our climate changes, we are experiencing more unusual and extreme weather. In addition to the devastating impact recently of Typhoon Haiyan in the Philippines,  cities everywhere are regularly experiencing the effects to a more modest degree.

One city in the UK told me recently that inside the last 12 months they have dealt with such an increase in incidents of flooding severe enough to require coordinated cross-city action that it has become an urgent priority for local Councillors. We are working with other cities in Europe to understand the effect of rising average levels of flooding – historic building construction codes mean that a rise in average levels of a meter or more could put significant numbers of buildings at risk of falling down. The current prediction from the United Nations International Panel on Climate Change is that levels will rise somewhere between 26cm and 82cm by the end of this century – close enough for concern.

The EM-DAT International Disasters Database has calculated the financial impact of natural disasters over the past century. They have shown that in recent years the increased occurrence of unusual and extreme weather combined with the increasing concentration of populations and economic activity in cities has caused this impact to rise at previously unprecedented rates.

The investment markets have identified and responded to this trend. In their recent report “Global Investor Survey on Climate Change”, the Global Investor Coalition on Climate Change reported this year that 53% of fund managers collectively responsible for $14 trillion of assets indicated that they had divested stocks, or chosen not to invest in stocks, due to concerns over the impact of climate change on the businesses concerned. We have passed a tipping point; the world has changed.

The dawn of the Information Revolution

Tipping point 4: exponential growth in the world’s most powerful man-made resource, digital information

Information has always been crucial to our world. Our use of language to share it is arguably a defining characteristic of what it means to be human; it is the basis of monetary systems for mediating the exchange of goods and services; and it is a core component of quantum mechanics, one of the most fundamental physical theories that describes how our universe behaves.

But the emergence of broadband and mobile connectivity over the last decade have utterly transformed the quantity of recorded information in the world and our ability to exploit it.

EMC’s Digital Universe report shows that in between 2010 and 2012 more information was recorded than in all of previous human history. They predict that the quantity of information recorded will double every 2 years, meaning that at any point in the next two decades it will be true to make the same assertion that “more information was recorded in the last two years than in all of previous history”. In 2011 McKinsey described the “information economy” that has emerged to exploit this information as a fundamental shift in the basis of the economy as a whole.

Not only that, but information has literally been turned into money. The virtual currency Bitcoin is based not on the value of a raw material such as gold whose availability is physically limited; but on the outcomes of extremely complex cryptographic calculations whose performance is limited by the speed at which computers can process information. The value of Bitcoins is currently rising incredibly quickly – from $20 to $1000 since January; although it is also subject to significant fluctuations. 

Ultimately, Bitcoin itself may succeed or fail – and it is certainly used in some unethical and dangerous transactions as well as by ordinary people and businesses. But its model has demonstrated in principle that a decentralised, non-national, information-based currency can operate successfully, as my colleague Richard Brown recently explained.

Digital information is the most valuable man-made resource ever invented; it began a period of exponential growth just three years ago and has literally been turned into money. We have passed a tipping point; the world has changed.

Tipping point 5: the disappearing boundary between humans, information and the physical world

In the 1990s the internet began to change the world despite the fact that it could only be accessed by using an expensive, heavy personal computer; a slow and inconvenient telephone modem; and the QWERTY keyboard that was designed in the 19th Century to prevent typists from typing faster than the levers in mechanical typewriters could move.

Three years ago, my then 2-year-old son taught himself how to use a touchscreen tablet to watch cartoons from around the world before he could read or write. Two years ago, Scientists at the University of California at Berkeley used a Magnetic Resonance Imaging facility to capture images from the thoughts of a person watching a film. A less sensitive mind-reading technology is already available as a headset from Emotiv, which my colleagues in IBM’s Emerging Technologies team have used to help a paralysed person communicate by thinking directional instructions to a computer.

Earlier this year, a paralysed woman controlled a robotic arm by thought; and prosthetic limbs, a working gun and living biological structures such as muscle fibre and skin are just some of the things that can be 3D printed on demand from raw materials and digital designs.

Our thoughts can control information in computer systems; and information in those systems can quite literally shape the world around us. The boundaries between our minds, information and the physical world are disappearing. We have passed a tipping point; the world has changed.

Tipping point 6: the miniaturisation of industry

The emergence of the internet as a platform for enabling sales, marketing and logistics over the last decade has enabled small and micro-businesses to reach markets across the world that were previously accessible only to much larger organisations with international sales and distribution networks.

More recently, the emergence and maturation of technologies such as 3D printingopen-source manufacturing and small-scale energy generation are enabling small businesses and community initiatives to succeed in new sectors by reducing the scale at which it is economically viable to carry out what were previously industrial activities – a trend recently labelled by the Economist magazine as the “Third Industrial Revolution“. The continuing development of social media and pervasive technology enable them to rapidly form and adapt supply and exchange networks with other small-scale producers and consumers.

Estimates of the size of the resulting “sharing economy“, defined by Wikipedia as “economic and social systems that enable shared access to goods, services, data and talent“, vary widely, but are certainly significant. The UK Economist magazine reports one estimate that it is a $26 billion economy already, whilst 2 Degrees Network report that just one aspect of it – small-scale energy generation – could save UK businesses £33 billion annually by 2030Air B’n’B – a peer-to-peer accommodation service – reported recently that they had contributed $632 million in value to New York’s economy in 2012 by enabling nearly 5,000 residents to earn an average of $7,500 by renting their spare rooms to travellers; and as a consequence of those travellers additionally spending an average of $880 in the city during their stay. Overall, there has been a significant rise in self-employment and “micro-entrepreneurial” enterprises over the last few years, which now account for 14% of the US economy.

Organisations participating in the sharing economy exhibit a range of motivations and ethics – some are aggressively commercial, whilst others are “social enterprises” with a commitment to reinvest profits in social growth. The social enterprise sector, comprised of mutuals, co-operatives, employee-owned businesses and enterprises who submit to “triple bottom line” accounting of financial, social and environmental capital, is about 15% of the value of most economies, and has been growing and creating jobs faster than traditional business since the 2008 crash.

In the first decade of the 21st Century, mobile and internet technologies caused a convergence between the technology, communications and media sectors of the economy. In this decade, we will see far more widespread disruptions and convergences in the technology, manufacturing, creative arts, healthcare and utilities industries; and enormous growth in the number of small and social enterprises creating innovative business models that cut across them. We have passed a tipping point; the world has changed.

Rebalancing the world

Tipping point 7: how we respond to climate change and resource constraints

There is now agreement amongst scientists, expressed most conclusively by the United Nations International Panel on Climate Change this year, that the world is undergoing a period of overall warming resulting from the impact of human activity. But there is not yet a consensus on how we should respond.

Views vary from taking immediate, sweeping measures to drastically cut carbon and greenhouse gas emissions,  to the belief that we should accept climate change as inevitable and focus investment instead on adapting to it, as suggested by the “Skeptical Environmentalist” Bjørn Lomborg and the conservative think-tank the American Enterprise Institute. As a result of this divergence of opinion, and of the challenge of negotiating between the interests of countries, communities and businesses across the world, the agreement reached by last year’s climate change negotiations in Doha was generally regarded as relatively weak.

Professor Chris Rogers of the University of Birmingham and his colleagues in the Urban Futures initiative have assessed over 450 proposed future scenarios and identified four archetypes (described in his presentation to Base Cities Birmingham) against which they assess the cost and effectiveness of environmental and climate interventions. The “Fortress World” scenario is divided between an authoritarian elite who control the world’s resources from their protected enclaves and a wider population living in poverty. In “Market Forces”, free markets encourage materialist consumerism to wholly override social and environmental values; whilst in “Policy Reform” a combination of legislation and citizen behaviour change achieve a balanced outcome. And in the “New Sustainability Paradigm” the pursuit of wealth gives way to a widespread aspiration to achieve social equality and environmental sustainability. (Chris is optimistic enough that his team dismissed another scenario, “Breakdown”, as unrealistic).

Decisions that are taken today affect the degree to which our world will evolve to resemble those scenarios. As the impact of weather and competition for resources affect the stability of supply of energy and foodmany cities are responding to the relative lack of national and international action by taking steps themselves. Some businesses are also building strategies for long-term success and profit growth  around sustainability; in part because investing in a resilient world is a good basis for a resilient business, and in part because they believe that a genuine commitment to sustainability will appeal to consumers. Unilever demonstrated that they are following this strategy recently by committing to buy all of their palm oil – of which they consume one third of the world’s supply – from traceable sources by the end of 2014.

At some point, we will all – individuals, businesses, communities, governments – be forced to change our behaviour to account for climate change and the limits of resource availability: as the prices of raw materials, food and energy rise; and as we are more and more directly affected by the consequences of a changing environment.

The questions are: to what extent have these challenges become urgent to us already; and how and when will we respond?

(“Makers” at the Old Print Works in Balsall Heath, Birmingham, sharing the tools, skills and ideas that create successful small businesses)

Tipping point 8: the end of the average career

In “The End of Average“, the economist Tyler Cowen observed that about 60% of the jobs lost during the 2008 recession were in mid-wage occupations; and the UK Economist magazine reported that many jobs lost from professional industries had been replaced in artisan trades and small-scale industry such as food, furniture and design.

Echoing Jeremy Grantham, Cowen further observes that these changes take place within a much longer term 28% decline in middle-income wages in the US between 1969 and 2009 which has no identifiable single cause. Cowen worries that this is a sign that the economy is beginning to diverge into the authoritarian elite and the impoverished masses of Chris Rogers’ “Fortress World” scenario.

Other evidence points to a more complex picture. Jake Dunagan, Research Director of the Institute for the Future, believes that the widespread availability of digital technology and information is extending democracy and empowerment – just as the printing press and education did in the last millennium as they dramatically increased the extent to which people were informed and able to make themselves heard. Dunagan notes that through our reliance on technology and social media to find and share information, our thoughts and beliefs are already formed by, and having an effect on, society in a way that is fundamentally new.

The miniaturisation of industry (tipping point 6 above) and the disappearance of the boundary between our minds and bodies, information and the physical world (tipping point 5 above) are changing the ways in which resources and value are exchanged and processed out of all recognition. Just imagine how different the world would be if a 3D-printing service such as Shapeways transformed the manufacturing industry as dramatically as iTunes transformed the music industry 10 years ago. Google’s futurologist Thomas Frey recently described 55 “jobs of the future” that he thought might appear as a result.

(Activities comprising the “Informal Economy” and their linkages to the mainstream economy, by Claro Partners)

In both developed and emerging countries, informal, social and micro-businesses are significant elements of the economy, and are growing more quickly than traditional sectorsClaro partners estimate that the informal economy (in which they include alternative currencies, peer-to-peer businesses, temporary exchange networks and micro-businesses – see diagram, right) is worth $10 trillion worldwide, and that it employs up to 80% of the workforce in emerging markets. 

In developed countries, the Industrial Revolution drove a transformation of such activity into a more formal economy – a transformation which may now be in part reversing. In developing nations today, digital technology may make part of that transformation unnecessary. 

To be successful in this changing economy, we will need to change the way we learn, and the way we teach our children. Cowen wrote that “We will move from a society based on the pretense that everyone is given an okay standard of living to a society in which people are expected to fend for themselves much more than they do now”; and expressed a hope that online education offers the potential for cheaper and more widespread access to new skills to enable people to do so. This thinking echoes a finding of the Centre for Cities report “Cities Outlook 1901” that the major factor driving the relative success or failure of UK cities throughout the 20th Century was their ability to provide their populations with the right skills at the right time as technology and industry developed.

The marketeer and former Yahoo Executive Seth Godin’s polemic “Stop Stealing Dreams” attacked the education system for continuing to prepare learners for stable, traditional careers rather than the collaborative entrepreneurialism that he and other futurists expect to be required. Many educators would assert that their industry is already adapting and will continue to do so – great change is certainly expected as the ability to share information online disrupts an industry that developed historically to share it in classrooms and through books.

Many of the businesses, jobs and careers of 2020, 2050 and 2100 will be unrecognisable or even unimaginable to us today; as are the skills that will be needed to be successful in them. Conversely, many post-industrial cities today are still grappling with challenges created by the loss of jobs in manufacturing, coalmining and shipbuilding industries in the last century.

The question for our future is: will we adapt more comfortably to the sweeping changes that will surely come to the industries that employ us today?

Tipping point 9: inequality

The benefits of living in cities are distributed extremely unevenly.

The difference in life expectancy of children born into the poorest and wealthiest areas of UK cities today is often as much as 20 years – for boys in Glasgow the difference is 28 years. That’s a deep inequality in the opportunity to live.

There are many causes of that inequality, of course: health, diet, wealth, environmental quality, peace and public safety, for example. All of them are complex, and the issues that arise from them to create inequality – social deprivation and immobility, economic disengagement, social isolation, crime and lawlessness – are notoriously difficult to address.

But a fundamental element of addressing them is choosing to try to do so. That’s a trite observation, but it is nonetheless the case that in many of our activities we do not make that choice – or, more accurately, as individuals, communities and businesses we take choices primarily in our own interests rather than based on their wider impact.

Writing about cities in the 1960s, the urbanist Jane Jacobs observed that:

“Private investment shapes cities, but social ideas (and laws) shape private investment. First comes the image of what we want, then the machinery is adapted to turn out that image. The financial machinery has been adjusted to create anti-city images because, and only because, we as a society thought this would be good for us. If and when we think that lively, diversified city, capable of continual, close- grained improvement and change, is desirable, then we will adjust the financial machinery to get that.”

In many respects, we have not shaped the financial machinery of the world to achieve equality. Nobel Laureate Joseph Stiglitz wrote recently that in fact the financial machinery of the United States and the UK in particular create considerable inequality in those countries; and the Economist magazine reminds us of the enormous investments made into public institutions in the past in order to distribute the benefits of the Industrial Revolution to society at large rather than concentrate them on behalf of business owners and the professional classes – with only partial success.

New legislation in banking has been widely debated and enacted since the 2008 financial crisis – enforcing the separation of commercial and investment banking, for example. But addressing inequality is a much broader challenge than the regulation of banking, and will not only be addressed by legislation. Business models such as social enterprise, cross-city collaborations and the sharing economy are emerging to develop sustainable businesses in industries such as food, energy, transportation and finance, in addition to the contribution made by traditional businesses building sustainability into their strategies.

Whenever we vote, buy something or make a choice in business, we contribute to our overall choice to develop a fairer, more sustainable world in which everyone has a chance to participate. The question is not just whether we will take those choices; but the degree to which their impact on the wider world will be apparent to us so that we can do so in an informed way.

That is a challenge that technology can help with.

(A smartphone alert sent to a commuter in a San Francisco pilot project by IBM Research and Caltrans that provides personalised daily predictions of commuting journey times. The predictions gave commuters the opportunity to take a better-informed choice about their travel to work.)

Data and Choice

Like the printing press, the vote and education, access to data allows us to make more of a difference than we were able to without it.

Niall Firth’s November editorial for the New Scientist magazine describes how citizens of developing nations are using open data to hold their governments to account, from basic information about election candidates to the monitoring of government spending. In the UK, a crowd-sourced analysis of politicians’ expenses claims that had been leaked to the press resulted in resignations, the repayment of improperly claimed expenses, and in the most severe cases, imprisonment.

Unilever are committing to making their supply chain for palm oil traceable precisely because that data is what will enable them to next improve its sustainability; and in Almere, city data and analytics are being used to plan future development of the city in a way that doesn’t cause harmful impacts to existing citizens and residents. Neither initiative would have been possible or affordable without recent improvements in technology.

Data and technology, appropriately applied, give us an unprecedented ability to achieve our long-term objectives by taking better-informed, more forward-looking decisions every day, in the course of our normal work and lives. They tell us more than we could ever previously have known about the impact of those decisions.

That’s why the tipping points I’ve described in this article matter to me. They translate my general awareness that I should “do the right thing” into a specific knowledge that at this point in time, my choices in many aspects of daily work and life contribute to powerful forces that will shape the next century that we share on this planet; and that they could help to tip the balance in all of our favour.

The sharing economy and the future of movement in smart, human-scale cities

("Visionary City" by William Robinson Leigh)

(William Robinson Leigh’s 1908 painting “Visionary City” envisaged future cities constructed from mile-long buildings of hundreds of stories connected by gas-lit skyways for trams, pedestrians and horse-drawn carriages. A century later we’re starting to realise not only that developments in transport and power technology have eclipsed Leigh’s vision, but that we don’t want to live in cities constructed from buildings on this scale.)

One of the defining tensions throughout the development of cities has been between our desire for quality of life and our need to move ourselves and the things we depend on around.

The former requires space, peace, and safety in which to work, exercise, relax and socialise; the latter requires transport systems which, since the use of horsedrawn transport in medieval cities, have taken up space, created noise and pollution – and are often dangerous. Enrique Penalosa, whose mayorship of Bogota was defined by restricting the use of car transport, often refers to the tens of thousands of children killed by cars on the world’s roads every year and his astonishment that we accept this as the cost of convenient transport.

This tension will intensify rapidly in coming years. Not only are our cities growing larger and denser, but according to the analysis of city systems by Professors Geoffrey West and Louis Bettencourt of the Los Alamos National Laboratory and Professor Ian Robertson’s study of human behaviour, our interactions within them are speeding up and intensifying.

Arguably, over the last 50 years we have designed cities around large-scale buildings and transport structures that have supported – and encouraged – growth in transport and the size of urban economies and populations at the expense of some aspects of quality of life.

Whilst standards of living across the world have improved dramatically in recent decades, inequality has increased to an even greater extent; and many urbanists would agree that the character of some urban environments contributes significantly to that inequality. In response, the recent work of architects such as Jan Gehl and Kelvin Campbell, building on ideas first described by Jane Jacobs in the 1960s, has led to the development of the “human scale cities” movement with the mantra “first life, then space, then buildings”.

The challenge at the heart of this debate, though, is that the more successful we are in enabling human-scale value creation; the more demand we create for transport and movement. And unless we dramatically improve the impact of the systems that support that demand, the cities of the future could be worse, not better, places for us to live and work in.

Human scale technology creates complexity in transport

As digital technology pervades every aspect of our lives, whether in large-scale infrastructures such as road-use charging systems or through the widespread adoption of small-scale consumer technology such as smartphones and social media, we cannot afford to carry out the design of future cities without considering it; nor can we risk deploying it without concern for its affect on the quality of urban life.

Digital technologies do not just make it easier for us to communicate and share information wherever we are: those interactions create new opportunities to meet in person and to exchange goods and services; and so they create new requirements for transport. And as technologies such as 3D printing, open-source manufacturing and small-scale energy generation make it possible to carry out traditionally industrial activities at much smaller scales, some existing bulk movement patterns will be replaced by thousands of smaller, peer-to-peer interactions created by transactions in online marketplaces. We can already see the effects of this trend in the vast growth of traffic delivering goods that are purchased or exchanged online.

Estimates of the size of this “sharing economy“, defined by Wikipedia as “economic and social systems that enable shared access to goods, services, data and talent“, vary widely, but are certainly significant. The UK Economist magazine reports one estimate that it is a $26 billion economy already, whilst 2 Degrees Network report that just one aspect of it – small-scale energy generation – could save UK businesses £33 billion annually by 2030Air B’n’B – a peer-to-peer accommodation service – reported recently that they had contributed $632 million in value to New York’s economy in 2012 by enabling nearly 5,000 residents to earn an average of $7,500 by renting their spare rooms to travellers; and as a consequence of those travellers additionally spending an average of $880 in the city during their stay. The emergence in general of the internet as a platform for enabling sales, marketing and logistics for small and micro-businesses is partly responsible for a significant rise in self-employment and “micro-entrepreneurial” enterprises over the last few years, which now account for 14% of the US economy.

Digital technology will create not just great growth in our desire to travel and move things, but great complexity in the way we will do so. Today’s transport technologies are not only too inefficient to scale to our future needs; they’re not sophisticated and flexible enough to cope with the complexity and variety of demand.

Many of the future components of transport systems have already been envisaged, and deployed in early schemes: elevated cycleways; conveyor belts for freight; self-driving vehicles and convoys; and underground pneumatic networks for recycling. And to some extent, we have visualised the cities that they will create: Professor Miles Tight, for example, has considered the future living scenarios that might emerge from various evolutions of transport policy and human behavioural choices in the Visions 2030 project.

The task for the Smarter Cities movement should be to extend this thinking to envision the future of cities that are also shaped by emerging trends in digital technology and their effect on the wider economy and social systems. We won’t do that successfully by considering these subjects separately or in the abstract; we need to envision how they will collectively enable us to live and work from the smallest domestic scale to the largest city system.

What we’ll do in the home of the future

Rather than purchasing and owning goods such as kitchen utensils, hobby and craft items, toys and simple house and garden equipment, we will create them on-demand using small-scale and open-source manufacturing technology and smart-materials. It will even be possible – though not all of us will choose to do so – to manufacture some food in this way.

Conversely, there will still be demand for handmade artisan products including clothing, gifts, jewellery, home decorations, furniture, and food. Many of us will earn a living producing these goods in the home while selling and marketing them locally or through online channels.

So we will leave our home of the future less often to visit shops; but will need not just better transport services to deliver the goods we purchase online to our doorsteps, but also a new utility to deliver the raw materials from which we will manufacture them ourselves; and new transport services to collect the products of our home industries and to deliver supplies to them.

We will produce an increasing amount of energy at home; whether from existing technologies such as solar panels or combined heat and power (CHP) systems; or through new techniques such as bio-energy. The relationships between households, businesses, utilities and transportation will change as we become producers of energy and consumers of waste material.

And whilst remote working means we will continue to be less likely to travel to and from the same office each day, the increasing pace of economic activity means that we will be more likely to need to travel to many new destinations as it becomes necessary to meet face to face with the great variety of customers, suppliers, co-workers and business partners with whom online technologies connect us.

What we’ll do in the neighbourhoods of the future

As we increasingly work remotely from within our homes or by travelling far away from them, less of us work in jobs and for businesses that are physically located within the communities in which we live; and some of the economic ties that have bound those communities in the past have weakened. But most of us still feel strong ties to the places we live in; whether they are historical, created by the character of our homes or their surrounding environment, or by the culture and people around us. These ties create a shared incentive to invest in our community.

Perhaps the greatest potential of social media that we’re only begin to exploit is its power to create more vibrant, sustainable and resilient local communities through the “sharing economy”.

The motivations and ethics of organisations participating in the sharing economy vary widely – some are aggressively commercial, whilst others are “social enterprises” with a commitment to reinvest profits in social growth. The social enterprise sector, comprised of mutuals, co-operatives, employee-owned businesses and enterprises who submit to “triple bottom line” accounting of financial, social and environmental capital, is about 15% of the value of most economies, and has been growing and creating jobs faster than traditional business since the 2008 crash. There is enormous potential for cities to achieve their “Smarter” objectives for sustainable, equitably distributed economic growth through contributions from social enterprises using technology to implement sharing economy business models within their region.

Sharing economy models which enable transactions between participants within a walkable or cyclable area can be a particularly efficient mechanism for collaboration, as the related transport can be carried out using human power. Joan Clos, Exective Director of UN-Habitat, has asserted that cities will only become sustainable when they are built at a sufficient population density that a majority of interactions within them can be carried out in this way (as reported informally by Tim Stonor from Dr. Clos’s remarks at the “Urban Planning for City Leaders” conference at the Crystal, London in 2012).

The Community Lovers’ Guide has published stories from across Europe of people who have collaborated to make the places that they share better, often using technology; and schemes such as Casserole Club and Land Share are linking the supply and demand of land, food, gardening and cooking skills within local communities, helping neighbours to help each other. At local, national and international levels, sharing economy ideas are creating previously unrealised social and economic value, including access to employment opportunities that replace some of those traditional professions that are shrinking as the technology used by industrial business changes.

Revenue-earning businesses are a necessary component of vibrant communities, at a local neighbourhood scale as well as city-wide. At the Academy of Urbanism Congress in Bradford this year, Michael Ward, Chair of the Centre for Local Economic Strategies, asserted that “the key task facing civic leaders in the 21st Century is this: how, in a period of profound and continuing economic changes, will our citizens earn a living and prosper?”

So whilst we work remotely from direct colleagues, we may chose to work in a collaborative workspace with near neighbours, with whom we can exchange ideas, make new contacts and start new enterprises and ventures. As the “maker” economy emerges from the development of sophisticated, small-scale manufacturing, and the resurgence in interest in artisan products, community projects such as the Old Print Works in Balsall Heath, Birmingham are emerging in low-cost ex-industrial space as people come together to share the tools and expertise required to make things and run businesses.

We will also manage and share our use of resources such as energy and water at neighbourhood scale. The scale and economics of movement of the raw materials for bio-energy generation, for example, currently dictate that neighbourhood-scale generation facilities – as opposed to city-wide, regional or domestic scale – are the most efficient. Aston University’s European Bio-Energy Research Institute is demonstrating these principles in the Aston district of Birmingham. And schemes from the sustainability pilot in Dubuque, Iowa to the Energy Sharing Co-operative in the West Midlands of the UK and the Chale community project on the Isle of Wight have shown that community-scale schemes can create shared incentives to use resources more efficiently.

One traditional centre of urban communities, the retail high street or main street, has fared badly in recent times. The shift to e-commerce, supermarkets and out-of-town shopping parks has led to many of them loosing footfall and trade, and seeing “payday lenders“, betting shops and charity shops take the place of traditional retailers.

High streets needs to be freed from the planning, policy and tax restrictions that are preventing their recovery. The retail-dominated highstreet of the 20th century emerged from a particular and temporary period in the evolution of the private car as the predominant form of transport supporting household-scale economic transactions. Developments in digital and transport technology as well as economy and society have made it non-viable in its current form; but legislation that prevents change in the use of highstreet property, and that keeps business taxes artificially high, is preventing highstreets from adapting in order to benefit from technology and the opportunities of the sharing economy.

Business Improvement Districts, already emerging in the UK and US to replace some local authority services, offer one way forward. They need to be given more freedom to allow the districts they manage to develop as best meets the economic and social needs of their area according to the future, not the past. And they need to become bolder: to invest in the same advanced technology to maximize footfall and spend from their customers as shopping malls do on behalf of their tenants, as recommended by a recent report to UK Government on the future of the high street.

The future high street will not be a street of clothes shops, bookshops and banks: some of those will still exist, but the high street will also be a place for collaborative workers; for makers; for sharing and exchanging; for local food produce and artisan goods; for socialising; and for starting new businesses. We will use social media to share our time and our resources in the sharing economy; and will meet on the high street when those transactions require the exchange of physical goods and services. We will walk and cycle to local shops and transport centres to collect and deliver packages for ourselves, or for our neighbours.

The future of work, life and transport at city-scale

Whilst there’s no universally agreed definition, an urban areas is generally agreed to be a continuously built-up area with a total population of between 2,000 and 40 million people; living at a density of around 1,000 per square kilometre; and employed primarily in non-agricultural activities (the appendices to the 2007 revision of the UN World Urbanisation Prospects summarise such criteria from around the world; 38.7 million is estimated to be the population of the world’s largest city, Tokyo, in 2025 by the UN World Urbanisation Prospects 2011).

(An analysis based on GPS data from mobile phones of end-to-end journeys undertaken by users of Abidjan’s bus services. By comparing existing bus routes to end-to-end journey requirements, the analysis identified four new bus routes and led to changes in many others. As a result, 22 routes now show increased ridership, and city-wide journey times have decreased by 10%.)

That is living at an industrial scale. The sharing economy may be a tremendously powerful force, but – at least for the foreseeable future – it will not scale to completely replace the supply chains that support the needs of such enormous and dense populations.

Take food, for example. One hectare of highly fertile, intensively farmed land can feed 10 people. Birmingham, my home city, has an area of 60,000 hectares of relatively infertile land, most of which is not available for farming at all; and a population of around 1 million. Those numbers don’t add up to food self-sufficiency; and Birmingham is a very low-density city – between one-half and one-tenth as dense as the growing megacities of Asia and South America.

Until techniques such as vertical farming and laboratory-grown food become both technically and economically viable, and culturally acceptable – if they ever do – cities will not feed themselves. And these techniques hardly represent locally-grown food exchanged between peers – they are highly technical and likely to operate initially at industrial scale. Sharing economy businesses such as Casserole Club, Kitchen Surfing, and Big Barn will change the way we distribute, process and prepare food within cities, but many of the raw materials will continue to be grown and delivered to cities through the existing industrial-scale distribution networks that import them from agricultural regions.

We are drawn to cities for the opportunities they offer: for work, for entertainment, and to socialise. As rapidly as technology has improved our ability to carry out all of those activities online, the world’s population is still increasingly moving to cities. In many ways, technology augments the way we carry out those activities in the real world and in cities, rather than replacing them with online equivalents.

Technology has already made cultural events in the real world more frequent, accessible and varied. Before digital technology, the live music industry depended on mass-marketing and mass-appeal to create huge stadium-selling tours for a relatively small number of professional musicians; and local circuits were dominated by the less successful but similar-sounding acts for which sufficiently large audiences could be reached using the media of the time. I attempted as an amateur musician in the pre-internet 1990s to find a paying audience for the niche music I enjoyed making: I was not successful. Today, social media can be used to identify and aggregate demand to make possible a variety of events and artforms that would never previously have reached an audience. Culture in the real-world is everywhere, all the time, as a result, and life is the richer for it. We discover much of it online, but often experience it in the real world.

Flashmobs” use smartphones and social media to spontaneously bring large numbers of people together in urban spaces to celebrate; socialise or protest; and while we will play and tell stories in immersive 3D worlds in the future – whether we call them movies, interactive fiction or “massive multi-player online role-playing games” – we’ll increasingly do so in the physical world too, in “mixed reality” games. Technologies such as Google Glasscognitive computing and Brain/Computer Interfaces will accelerate these trends as they remove the barrier between the physical world and information systems.

We will continue to come to city centres to experience those things that they uniquely combine: the joy and excitement of being amongst large numbers of people; the opportunity to share ideas; access to leading-edge technologies that are only economically feasible at city-scale; great architecture, culture and events; the opportunity to shop, eat, drink and be entertained with friends. All of these things are possible anywhere; but it is only in cities that they exist together, all the time.

The challenge for city-scale living will be to support the growing need to transport goods and people into, out of and around urban areas in a way that is efficient and productive, and that minimises impact on the liveability of the urban environment. In part this will involve reducing the impact of existing modes of transport by switching to electric or hydrogen power for vehicles; by predicting and optimising the behaviour of traffic systems to prevent congestion; by optimising public transport as IBM have helped AbidjanDublin, Dubuque and Istanbul to do; and by improving the spatial organisation of transport through initiatives such as Arup’s Regent Street delivery hub.

We will also need new, evolved or rejuvenated forms of transport. In his lecture for the Centenary of the International Federation for Housing and Planning, Sir Peter Hall spoke eloquently of the benefits of Bus Rapid Transit systems, urban railways and trams. All can combine the speed and efficiency of rail for bringing goods and people into cities quickly from outlying regions, with the ability to stop frequently at the many places in cities which are the starting and finishing points of end-to-end journeys.

Vehicle journeys on major roads will be undertaken in the near future by automated convoys travelling safely at a combined speed and density beyond the capability of human drivers. Eventually the majority of journeys on all roads will be carried out by such autonomous vehicles. Whilst it is important that these technologies are developed and introduced in a way that emphasises safety, the majority of us already trust our lives to automated control systems in our cars – every time we use an anti-lock braking system, for example. We will still drive cars for fun, pleasure and sport in the future – but we will probably pay dearly for the privilege; and our personal transport may more closely resemble the rapid transit pods that can already be seen at Heathrow Terminal 5.

Proposals intended to accelerate the adoption of autonomous vehicles include the “Qwik lane” elevated highway for convoy traffic; or the “bi-modal glideway” and “tracked electric vehicle” systems which could allow cars and lorries to travel at great speed safely along railway networks or dedicated “tracked” roads. Alternative possibilities which could achieve similar levels of efficiency and throughput are to extend the use of conveyor belt technology – already recognised as far more efficient than lorries for transporting resources and goods over distances of tens of miles in quarries and factories – to bring freight in and out of cities; or to use pneumatically powered underground tunnel networks, which are already being used in early schemes for transporting recyclable waste in densely populated areas. Elon Musk, the inventor of the Tesla electric supercar, has even suggested that a similar underground “vacuum loop” could be used to replace long-distance train and air travel for humans, at speeds over 1000 kilometres per hour.

The majority of these transport systems won’t offer us as individuals the same autonomy and directness in our travel as we believe the private car offers us today – even though that autonomy is often severely restricted by traffic congestion and delays. Why will we chose to relinquish that control?

Some of us will simply prefer to, finding different value in other ways to get around.

Walking and cycling are gaining in popularity over driving in many cities. I’ve personally found it a revelation in recent years to walk around cities rather than drive around them as I might previously have done. Cities are interesting and exciting places, and walking is often an enjoyable as well as efficient way of moving about them. (And for urbanists, of course, walking offers unparalleled opportunities to understand cities). Many of us are also increasingly conscious of the health benefits of walking and cycling, particularly as recent studies in the UK and US have shown that adults today will be the first generation in recorded history to die younger than their parents because of our poor diets and sedentary lifestyles.

Alternatively, we may choose to travel by public transport in the interests of productivity – reading or working while we travel, especially as network coverage for telephony and the internet improves. As the world’s population and economies grow, competition and the need to improve productivity will lead more and more of us to this take this choice.

It is increasingly easy to walk, cycle, or use public or shared transport to travel into and around cities thanks to the availability of bicycle hire schemes, car clubs and walking route information services such as walkit.com. The emergence of services that provide instant access to travel information across all forms of transport – such as the Moovel service in Germany or the Optimod service in Lyon, France – will enhance this usability, making it easier to combine different forms of transport into a single journey, and to react to delays and changes in plans whilst en route.

Legislation will also drive changes in behaviour, from national and international initiatives such as the European Union legislation limiting carbon emissions of cars to local planning and transport policies – such as Birmingham’s recent Mobility Action Plan which announced a consultation to consider closing the city’s famous system of road tunnels.

Are we ready for the triumph of the digital city?

Regardless of the amazing advances we’re making in online technology, life is physical. Across the world we are drawn to cities for opportunity; for life-support; to meet, work and live.  The ways in which we interact and transport ourselves and the goods we exchange have changed out of all recognition throughout history, and will continue to do so. The ever increasing level of urbanisation of the world’s population demonstrates that there’s no sign yet that those changes will make cities redundant: far from it, they are thriving.

It is not possible to understand the impact on our lives of new ideas in transport, technology or cities in isolation. Unless we consider them together and in the context of changing lifestyles, working patterns and economics, we won’t design and build cities of the future to be resilient, sustainable, and equitable.  The limitation of our success in doing that in the past is illustrated by the difference in life expectancy of 20 years between the richest and poorest areas of UK cities; the limitation of our success in doing so today is illustrated by the fact that a huge proportion of the world’s population does not have access to the digital technologies that are changing our world.

I recently read the masterplan for a European city district regarded as a good example of Smart City thinking. It contained many examples of the clever and careful design of physical space for living and for today’s forms of transport, but did not refer at all to the changes in patterns of work, life and movement being driven by digital technology. It was certainly a dramatic improvement over some plans of the past; but it was not everything that a plan for the future needs to be. 

Across domains such as digital technology, urban design, public policy, low carbon engineering, economic development and transport we have great ideas for addressing the challenges that urbanisation, population growth, resource constraints and climate change will bring; but a lot of work to do in bringing them together to create good designs for the liveable cities of the future.
