This book analyses comprehensively the experiences from different parts of the world on how specific water development projects have influenced regional development so that positive and negative lessons can be learnt and processes can be improved. By synthesizing these experiences and learning from these findings, it should be possible to plan, design, implement, and operate future water projects better, so that they can contribute more to regional income distribution, poverty alleviation and environmental protection, than what have been witnessed in the past. It is also hoped that the facts, figures and analyses contained in the case studies of this book will encourage all parties to discuss objectively and constructively how best water development projects can be used in developing countries to accelerate regional development, contribute directly poverty alleviation and improve the quality of life of people in the regions concerned. Case studies are analyzed on water resources development in cities, countries and river basins in several parts of the world.
