, 2012
by: United Nations Department of Economic and Social Affairs (UNDESA)

This study highlights some of the top challenges and priorities for the next 30-50 years in the urban sector and illustrates the increasing role of cities for achieving sustainability. The study takes stock of developments in the urban agenda since 1992 and outlines some of cities' new responsibilities linked with rapid urbanization and metropolitanization. It makes a case for integrated action to solve urban sustainability challenges, including governance and inclusion, and explores the vertical relationships between cities and higher levels of government and their implications for sustainability.
