Entirely updated in light of the recent World Commission on Dams Report, and responding to it, this new edition of Patrick McCully's now classic study shows why large dams have become such a controversial technology in both industrialized and developing countries. He explores the wide-ranging ecological impacts of large dams, the human consequences, the organization of the dam-building industry, and the role played by international banks and aid agencies in promoting it. He also looks as the extensive technical, safety, and economic problems associated with large dams. New in this edition, the author tells the story of the rapid growth of the international anti-dam movement, and suggests alternative methods of supplying the services supposedly provided by large dams.

Patrick McCully is Campaigns Director of the California-based International Rivers Network. He is also an Associate Editor of The Ecologist and a contributing writer for Multinational Monitor.
