In far too many countries, the urban footprint is expanding faster than population. Urban sprawl, in turn, is not only creating (traffic) congestion but also adversely affecting livability, productivity, inclusion, and sustainability.

Sumila Gulyani of the World Bank discusses some old and new options for creating neighborhoods that provide decent living conditions for both the rich and poor—and how such approaches can help us build cities that are livable, inclusive, compact and sustainable.
