How to manage urban expansion in mega-metropolitan areas?

Philip E. Karp's picture

As the world becomes increasingly urbanized, the number of megacities is growing rapidly.

Today there are 37 cities worldwide with populations of greater than 10 million, and 84 with populations greater than five million. More than three quarters of these cities are in developing countries. Together with their surrounding metropolitan areas, these cities produce a sizable portion of the world’s wealth and attract a large share of global talent.

These megacities face a series of common challenges associated with managing urban expansion, density, and livability—in a manner that takes advantage of the benefits of productive agglomerations, while mitigating the disadvantages of such high degrees of congestion and urban density.

Moreover, like other metropolitan areas, megacities face challenges of effectively coordinated planning, infrastructure development, and service delivery across multiple jurisdictions. Indeed, the New Urban Agenda issued at the Habitat III conference in 2016 identified metropolitan planning and management as one of the most critical needs to ensure sustainable urbanization.

How to effectively manage metropolitan areas?

​Today, a quarter of the world’s population lives in urban “agglomerations”—supersized metropolitan areas that cut across jurisdictional boundaries and bring together one or more cities along with their surrounding areas.

These metropolitan areas face a common challenge: effectively coordinating planning, infrastructure development, and service delivery across multiple jurisdictions. This is particularly difficult in developing countries, which often lack the necessary legal, institutional, and governance apparatus to undertake such coordination. The New Urban Agenda issued by the Habitat III conference in 2016 identified metropolitan planning and management as one of the most critical needs to ensure sustainable urbanization.

Fortunately, there is growing evidence and good practice from various countries on how to effectively manage and govern metropolitan areas. To help spread existing good practice and co-create new solutions, the World Bank has been supporting a community of practice (CoP) on metropolitan governance, or MetroLab, which brings together officials from metropolitan areas in both developing and developed countries for peer-peer knowledge and experience sharing.  Since its launch in 2013, MetroLab has held eight meetings in various cities, including Bangkok, Mumbai, New York, Paris, Rio de Janeiro, and Seoul.

​The most recent meeting took place in Tokyo from January 30 through February 2. Organized by the World Bank’s Tokyo Development Learning Center, the Tokyo MetroLab brought together mayors, city planners, and finance officials from nine developing cities. They were joined by experts from the World Bank, New York’s Regional Plan Association, the Seoul Metropolitan Government, and Advancity—Paris’ Smart Metropolis Hub.

In this video, Lydia Sackey-Addy, one of the participating officials from Accra, Ghana, as well as the World Bank’s Senior Director Ede Ijjasz-Vasquez (@Ede_WBG) and Lead Urban Economist Maria Angelica Sotomayor (@masotomayor) tell us how they are working together to make the Accra metropolitan area more resilient and sustainable for its residents.


 

Washington’s Cherry Blossoms: The Gift that Keeps Giving

Dan Hoornweg's picture

Cherry Trees, Washington, DCOne of the best things about living in Washington DC is riding your bike to work, early in the morning, past the blossoming cherry trees along the tidal basin. Sometimes you have to actually stop for a moment, the trees are so beautiful. Thank you, Governor (Mayor) Ozaki Yukio: He gave the trees to the up and coming Washington DC in 1912.

This year is the 100th anniversary of the City of Tokyo’s original gift of 3020 cherry trees. You would be hard pressed to find a more perfect gift, or a more perfect example of how the cities we live in, and the globally-minded ones overseas, improve our day-to-day quality of life.
