In many areas of the world, environmental degradation in and around human settlements is undermining prospects for both socioeconomic justice and ecological sustainability. To explore the issues involved in this worldwide problem, Keith Pezzoli focuses on a dramatic instance of conflict that grew out of the unauthorized penetration of human settlements into the Ajusco greenbelt zone, a vital part of Mexico City's ecological reserve. The heart of the book is the story of what happened when residents of the Ajusco settlements fought relocation by proposing that the areas be transformed into productive ecology settlements. Pezzoli draws upon urban and regional planning theory and practice to examine biophysical as well as ethical and social sides of the story, and he uses the Mexican experience to identify planning strategies to link economy, ecology, and community in sustainable development. -- Publisher description.

This publication reviews recent urban planning practices and approaches, discusses constraints and conflicts therein, and identifies innovative approaches that are more responsive to current challenges of urbanization. It notes that traditional approaches to urban planning (particularly in developing countries) have largely failed to promote equitable, efficient and sustainable human settlements and to address twenty-first century challenges, including rapid urbanization, shrinking cities and aging, climate change and related disasters, urban sprawl and unplanned peri-urbanization, as well as urbanization of poverty and informality. It concludes that new approaches to planning can only be meaningful, and have a greater chance of succeeding, if they effectively address all of these challenges, are participatory and inclusive, as well as linked to contextual socio-political processes.--Publisher's description

This text addresses the difficulties of balancing the imperatives of sustainability with the pressing challenges facing some of the world's most underdeveloped areas. Various perspectives are brought to bear on issues from economics and theories of health through to the foundations of sustainability. All the key contemporary developments are dealt with; the growth in international law and agreements on controlling greenhouse gases; the effect of reforms in finance, governance and methods of appraisal on the areas of waste management; and the theoretical advances in the community development aspects of health and the neighbourhood environment guided by the experiences of the World Bank, WHO and UNEP. The text is intended as a guidebook for those responsible for re-shaping cities in the 21st century.
