In this lecture, Dr Clos discusses planned versus spontaneous urbanization, the issues this entails and three concrete principles for planning sustainable cities. Together they form a three-legged approach to sustainable urbanization.

The lecture is based on the realization that the current urban planning paradigm championed in the United States and Europe—the Containment Paradigm, also known as urban growth management, smart growth, or compact city—is inappropriate in the rapidly-urbanizing countries in Asia, Africa and Latin America. Instead, it calls for a new paradigm for coming to terms with rapid urbanization: The Making Room Paradigm.
