“Without cities we would all be poor.”

- Jane Jacobs, The Economy of Cities

If Jacobs was right, and there’s good reason to believe that she was, the world in 2030 stands to be a much better place. According to UN estimates, the urban share of the world’s population will grow from just over 50 percent in 2010 to 60 percent in 2030. The vast majority of this urbanization will occur in the developing world, where urban areas are expected to add another 1.3 billion people by 2030.

There are two ways to accommodate this influx of urban residents: expand existing cities or build new ones. In both cases, weak and ineffective governance poses a significant challenge to successful urbanization. The graph below shows the negative relationship between a country’s score on the Rule of Law Index and its expected average annual rate of urban growth over the next four decades.

At the NYU Stern Urbanization Project (UP), we’re focused on urban growth strategies that account for the conditions of governance in the developing world. One initiative, led by Paul Romer, focuses on new cities — particularly the potential for new cities to advance reform and improve choices for urban migrants. Another initiative, led by Solly Angel, focuses on urban expansion.

Urban Expansion

With growing numbers of urban migrants, the physical expansion of developing world cities is inevitable. If incomes continue to rise relative to transport costs, the trend toward expansion will be even stronger. Such expansion needn’t be unsustainable. Because urban densities in the developing world are more than double those of Europe and Japan, they can decline considerably without inducing the sorts of suburban sprawl associated with land-rich developed countries like the United States.

Cities in developing countries should come to terms with urban expansion. Ignoring it won’t stop it. People will continue to arrive in an uncoordinated fashion, excluded from the formal sector and consigned to congested slums. Some planning will be necessary. But given the massive scale of urbanization and the governance constraints that characterize much of the developing world, overly intricate planning efforts may be just as likely to fail as no plan at all.

UP advocates for a lighter touch approach, one in which governments consolidate land for public space and arterial roads based on realistic forecasts of urban expansion. This approach ensures corridors for public service provision and effectively coordinates the private decisions that comprise the majority of urban development. By spacing arterial roads 1 kilometer apart the city can make public transport accessible to everyone; by making room for expansion the city can ensure that the supply of housing remains ample and affordable.

New Cities

Political risk in the developing world remains a key bottleneck to what would otherwise be relatively high-return investments in urban infrastructure. Policy innovations that mitigate political risk can channel enormous amounts of foreign investment into rapidly growing cities; investments that would in turn offer billions of people opportunities to work their way out of poverty. UP believes that charter cities—new cities built in special reform zones—offer a promising way to mitigate political risk and drive reform in the developing world.

The first country to adapt the charter cities concept to its development strategy was Honduras, a country whose urban population is expected to more than double in the next few decades. Seeing this urbanization as an opportunity for reform, the Honduran government established a new legal entity known locally as la Región Especial de Desarrollo (RED).   

Though part of sovereign Honduran territory, the RED will be largely autonomous. Critically, the RED will also have the power to partner with credible foreign allies, such as Canada and Mauritius, on core government functions including policing, jurisprudence, and a range of public service provision. Such partnerships can strengthen the rule of law in the RED, attracting investors, generating jobs, and providing safe new options for the millions of people in the region who currently lack them. The Honduran government believes that reform in the RED can complement the process of reform and reconciliation elsewhere in the country.

Enhancing Global Stability and Growth

Looking forward to 2030, UP is optimistic about the prospects for urbanization to enhance global stability and buoy trade and investment flows. We believe that inclusive urban planning strategies, grounded in the understanding that urban expansion is inevitable, are more likely to result in cities that are accessible, affordable, and peaceful. We also believe that new cities, based on innovative models of international cooperation, have an important role to play in driving reform, unlocking high-return investment opportunities, and improving the choices of urban migrants.
