Book excerpt: * Updated and much expanded edition of the authors' 1992 classic Environmental Problems in Third World Cities * Comprehensive account of the health- and life- threatening environmental conditions in which a growing proportion of the world's people live * Ideal as a textbook and for professionals and interested general readers * 1st edition widely adopted on urban geography, development studies, environmental courses Most of the world's urban population and most of the large and rapidly growing cities are in developing countries. Often poorly governed, their conditions produce millions of preventable deaths and extensive disease. This book describes these cities' environmental problems and how they affect health, local ecosystems and global cycles. It analyzes the causes: the failure of governments to supply clean water and implement existing measures, or land-owning structures that marginalize the poor. It also highlights the innovative ways in which problems are being tackled, showing solutions are available and the action needed by cities, local governments and community organizations.
