The global conversation about urban sustainability focuses primarily on the big picture: how to reduce the carbon footprint and energy consumption of cities? How can we provide the infrastructure and services necessary to meet the needs of a soaring urban population? How can cities create enough jobs for everyone?
These issues are critically important, no doubt. But what about the city itself as a physical space? What should a sustainable city "look like"? Are there any big design principles that all successful urban planners should follow?
Because urbanization is often a chaotic process, many countries feel like they don't have the time or resources to address those questions. Yet evidence has shown that considerations about urban form and design are anything but cosmetic: creating vibrant public spaces within a city, for instance, can boost competitiveness, improve health outcomes, and strengthen social cohesion.
In this video, Ede Ijjasz-Vasquez and Jon Kher Kaw delve deeper into the linkages between urban spaces and sustainability, and describe the many benefits that come with a well-designed city.

A paper, called Growing Cities Sustainably, was recently published in the Journal of the American Planning Association, which generated much debate on the benefits and disadvantages of the “compact” city model. The paper argues that for three studied regions in Britain, the current policy trend of promoting compact cities is actually economically and environmentally unsustainable. Britain has been very successful in implementing anti-sprawl policies, starting with the 1947 Town and Country Planning Act. The new paper compares the compaction model with planned expansion models in three urban regions and concludes “Smart growth principles should not unquestioningly promote increasing levels of compaction. In many cases, the potential socioeconomic consequences of less housing choice, crowding, and congestion may outweigh its very modest CO2 reduction benefits.”
