Building the BRICs: How can developing countries plan the cities of the future?

The UN estimates that more than 6bn people will live in cities by the year 2045 – compared with fewer than 4bn today. But these huge numbers hide subtle complexities. Every city is growing at a different rate, in its own distinctive direction – each one is an open, complex system, which generates cultural, economic and technological innovation by combining new materials with unique histories.

Clearly, there’s no single road map for the future which all cities can follow. But if urban areas are to grow sustainably, as well as coping with scarce resources, global warming, inequality, epidemics and natural disasters, then a global strategy is in order. To this end, in October, scholars, politicians, business people and community representatives gathered for the UN’s Habitat III conference in Quito, Ecuador, to agree on the “New Urban Agenda”.

Where to begin?

For those attending Habitat III, Brazil, India, China, and South Africa provide some of the best case studies of extreme division and extraordinary innovation in cities. Despite having very different histories, cities in these countries share several features, which make them useful when we want to compare how similar urban processes are playing out around the world.

Brazil urbanised much earlier than most of Asia and Africa, absorbing more than 80m people into its cities between 1970 and 2000. China has recently caught up; as of 2015, 56 per cent of its population was living in urban areas. India and South Africa are soon to follow: according to UN data from 2014, almost 40 per cent of India’s population, and 71 per cent of South Africa’s, will reside in urban areas by 2030.

Cities in these countries are experiencing a period of great change. Part of this is political: South Africa held municipal elections in August this year, followed by Brazil in October, while in India – which is on a five-year municipal election cycle – elections are often held when politically convenient. In each case, different political promises can invoke a wide range of possible urban futures.

The global shift of mega-events to BRICS (Brazil, Russia, India, South Africa) countries over the past decade has also caused an enormous upheaval in host cities. Examples include the 2008 Beijing Olympics, the 2010 South Africa World Cup, the 2010 Commonwealth Games in Delhi, the Sochi (Russia) Winter Olympics of 2014 and, of course, the 2014 World Cup and 2016 Olympic Games in Brazil.

These events have been catalysts for all kinds of harm and glory. While cases of Zika virus alarmed residents and visitors in one part of Rio, the new Bus Rapid Transport system improved transport links for the growing population in another.

Such contrasts are common in these countries. From slum evictions in South Africa, to modernist master-planning in Brazil; from experiments in participatory budgeting in more than 100 Brazilian cities to “nail houses” resisting mass development in China – these countries’ cities are often labelled both “problem case studies” and “great urban innovators”.

Taking the lead

Yet while these nations’ cities are attracting fresh attention, this hasn’t necessarily given urban leaders and citizens more power to predict, understand or determine their future. In particular, municipalities continue to rely heavily on national resources to cover local expenses, while mayors are bound to follow elaborate national regulations.

As cities grow, there’s pressure for city leaders to involve local communities in decisions. While this is ideal in theory, it can be unpredictable in practice. Local discussions can easily become a stage for the strongest voices or would-be politicians, or residents can retreat from such meetings entirely, to avoid confronting local economic and political powers, especially if residents live in informal houses or have irregular jobs.

From Bangalore to Cape Town, Shanghai to Sao Paulo, it is not uncommon for residents to start such meetings by stating their inability to participate. Many consultations take place during working hours, far removed from the site of interest. Some are presented in technical terms, formally offering a channel for participation but actually encouraging silence or absence from some members, while over-empowering others.

For example, a meeting in a city hall or public building to discuss an informal settlement can discourage participants from attending if they feel they do not possess the right clothes. From stigmatisation to transportation, problems with participatory practices run deep; it takes a lot more than simply offering people a channel to voice their concerns.

Locked in?

To really understand how a city will develop, it’s crucial to understand its “lock-ins” and “path dependencies”. Lock-ins are features of the built environment, which limit the potential of a city. For example, in Mumbai, regulations to facilitate the development of luxury condos in much of the city centre has generated infrastructure such as roads and car parks which work well for car drivers, but block possibilities for imagining public and green transport systems from the ground up.

Similarly, “path dependencies” occur where the history of the urban form inhibits some kinds of change and promotes others. For instance, in Rio, the long-established divisions between the city’s formal and informal settlements limit, but also shape, any future changes to the city.

Scientific research offers the opportunity to bring a greater understanding to the constantly shifting urban form. To that end, the UK’s Economic and Social Research Council has created a series of collaborative research projects, in partnership with China, Brazil and South Africa. Such research can reveal the metabolism of the city, mapping and measuring the lock-ins and path dependencies which structure the interdependent web of water, food and energy systems.

It can also analyse the way that transport systems can reproduce either segregation or integration, and how gendered divisions determine which places are safe or dangerous – and for whom. Enormous amounts of data, generated by citizens’ own behaviours, can be used to interpret the city as it evolves. Of course, all of these advancements trigger ethical questions, which demand longer reflection.


While every city’s future is unique, we can enrich our understanding with collaborations that explore the diversity of cities and draw comparisons across the world. Yet scientists face the challenging task of reconciling the long-term horizons of a city with the political motivations of urban democracy, which measure the future in electoral cycles.

Researchers have an obligation to highlight the trade offs, compromises and alternatives that ongoing elections and global UN summits might generate for each country’s unique urban future. They must bring short term and long term possibilities to the surface, and mitigate between them, if we’re ever to get a clear vision of the future of cities. The Conversation

CityMetric is now City Monitor! Come see us at our new home

City Monitor is now live in beta at citymonitor.ai.

CityMetric is now City Monitor, a name that reflects both a ramping up of our ambitions as well as our membership in a network of like-minded publications from New Statesman Media Group. Our new site is now live in beta, so please visit us there going forward. Here’s what CityMetric readers should know about this exciting transition.  

Regular CityMetric readers may have already noticed a few changes around here since the spring. CityMetric’s beloved founding editor, Jonn Elledge, has moved on to some new adventures, and a new team has formed to take the site into the future. It’s led by yours truly – I’m Sommer Mathis, the editor-in-chief of City Monitor. Hello!

My background includes having served as the founding editor of CityLab, editor-in-chief of Atlas Obscura, and editor-in-chief of DCist, a local news publication in the District of Columbia. I’ve been reporting on and writing about cities in one way or another for the past 15 years. To me, there is no more important story in the world right now than how cities are changing and adapting to an increasingly challenging global landscape. The majority of the world’s population lives in cities, and if we’re ever going to be able to tackle the most pressing issues currently facing our planet – the climate emergency, rising inequality, the Covid-19 pandemic ­­­– cities are going to have to lead the way.

That’s why City Monitor is now a global publication dedicated to the future of cities everywhere – not just in the UK (nor for that matter just in the US, where I live). Our mission is to help our readers, many of whom are in leadership positions around the globe, navigate how cities are changing and discover what’s next in the world of urban policy. We’ll do that through original reporting, expert opinion and most crucially, a data-driven approach that emphasises evidence and rigorous analysis. We want to arm local decision-makers and those they work in concert with – whether that’s elected officials, bureaucratic leaders, policy advocates, neighbourhood activists, academics and researchers, entrepreneurs, or plain-old engaged citizens – with real insights and potential answers to tough problems. Subjects we cover include transportation, infrastructure, housing, urban design, public safety, the environment, the economy, and much more.

The City Monitor team is made up of some of the most experienced urban policy journalists in the world. Our managing editor is Adam Sneed, also a CityLab alum where he served as a senior associate editor. Before that he was a technology reporter at Politico. Allison Arieff is City Monitor’s senior editor. She was previously editorial director of the urban planning and policy think tank SPUR, as well as a contributing columnist for The New York Times. Staff writer Jake Blumgart most recently covered development, housing and politics for WHYY, the local public radio station in Philadelphia. And our data reporter is Alexandra Kanik, whose previous roles include data reporting for Louisville Public Media in Kentucky and PublicSource in Pittsburgh, Pennsylvania.

Our team will continue to grow in the coming weeks, and we’ll also be collaborating closely with our editorial colleagues across New Statesman Media Group. In fact, we’re launching a whole network of new publications, covering topics such as the clean energy transition, foreign direct investment, technology, banks and more. Many of these sectors will frequently overlap with our cities coverage, and a key part of our plan is make the most of the expertise that all of these newsrooms combined will bring to bear on our journalism.

Please visit citymonitor.ai going forward, where you can also sign up for our free email newsletter.


As for CityMetric, some of its archives have already been moved over to the new website, and the rest will follow not long after. If you’re looking for a favourite piece from CityMetric’s past, for a time you’ll still be able to find it here, but before long the whole archive will move over to City Monitor.

On behalf of the City Monitor team, I’m thrilled to invite you to come along for the ride at our new digs. You can follow City Monitor on LinkedIn and on Twitter. If you’re interested in learning more about the potential for a commercial partnership with City Monitor, please get in touch with our director of partnerships, Joe Maughan.

I want to thank and congratulate Jonn Elledge on a brilliant run. Everything we do from here on out will be building on the legacy of his work, and the community that he built here at CityMetric. Cheers, Jonn!

To our readers, on behalf of the City Monitor team, thank you from all of us for being such loyal CityMetric fans. We couldn’t have done any of this without you.

Sommer Mathis is editor-in-chief of City Monitor.
