Planning in Cities is an innovative collection which bridges theory and practice to explore the conflicting challenges of the increasingly rapid scale and speed of city growth with providing effective urban planning policies and management strategies. Part One explores the changing paradigms of development and environmentalism and how these have impacted on the process of urbanization and the emerging debates on the sustainability of cities. These chapters review and elaborate the discourse on sustainability, setting it firmly within the context of urbanization and development. The increasing disjuncture between these concepts and the challenge this presents to the planning of cities in the developing world is highlighted. Part Two shifts from discourse to practice. Case studies drawn from different countries and different urban policy sectors investigate the design and implementation of planning policies and ways of improving urban governance to support sustainable urban growth. They assess the challenges and limitations to capacity-building in the urban sector. Lessons learned from different practical approaches are demonstrated and critiqued.
