The global conversation about urban sustainability focuses primarily on "big picture" policy issues. 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.
