One of the most controversial issues of the water sector in recent years has been the impacts of large dams. Proponents have claimed that such structures are essential to meet the increasing water demands of the world and that their overall societal benefits far outweight the costs. In contrast, the opponents claim that social and environmental costs of large dams far exceed their benefits, and that the era of construction of large dams is over. A major reason as to why there is no consensus on the overall benefits of large dams is because objective, authoritative and comprehensive evaluations of their impacts, especially ten or more years after their construction, are conspicuous by their absence. This book debates impartially, comprehensively and objectively, the positive and negative impacts of large dams based on facts, figures and authoritative analyses. These in-depth case studies are expected to promote a healthy and balanced debate on the needs, impacts and relevance of large dams, with case studies from Africa, Asia, Australia, Europe and Latin America.

This book explores the issue of development-induced resettlement, with a particular emphasis on the humanitarian, legal, and social aspects of this problem. Today, so-called 'development-induced displacement and resettlement' (DIDR) is one of the dominant causes of internal spatial mobility worldwide. Each year over 15 million people are forced to abandon their homes to make space for economic development infrastructure. The construction of dams and irrigation projects, the expansion of communication networks, urbanization and re-urbanization, the extraction and transportation of mineral resources, forced evictions in urban areas, and population redistribution schemes count among the many possible causes.Terminski aims to present the issue of development-caused displacement as a highly diverse, global social problem occurring in all regions of the world. As a human rights issue it poses a challenge to public international law and to institutions providing humanitarian assistance. A significant part of this book is devoted to the current dynamics of development-caused resettlement in Europe, which has been neglected in the academic literature so far.

This book targets the issue of water scarcity in Egypt as a typical example of the world water crisis. Today, the available water resource is facing its limit because of rapid increase in water demand as a result of population growth and changes in peoples’ life-style. The basic idea to solve the problem of water scarcity is that the irrigation sector, the biggest user of water, should increase water use efficiency. However, the real problem is how this can be achieved in view of the crucial need for water in this sector. This book addresses this challenge through case studies from the Nile delta in Egypt. The water problem in the Nile delta, the major source for water in Egypt, is discussed in this book from all its various aspects. This book covers the situation before and after the advent of the Aswan High Dam, so that the reader understands the entire development. Another special feature are the extensive and scientific descriptions of contemporary topics in water and agriculture, especially from the viewpoint of water saving and sustainability. These descriptions are based on field experiments and surveys in a six-year international research project. Topics of this book are local, but their implications are global.

By the year 2000, the world had built more than 45,000 large dams to irrigate crops, generate power, control floods in wet times and store water in dry times. Yet, in the last century, large dams also disrupted the ecology of half the world's rivers, displaced tens of millions of people from their homes and left nations burdened with debt. Their impacts have inevitably generated growing controversy and conflicts. Resolving their role in meeting water and energy needs is vital for the future and illustrates the complex development challenges that face our societies. The Report of the World Commission on Dams: - is the product of an unprecedented global public policy effort to bring governments, the private sector and civil society together in one process - provides the first comprehensive global and independent review of the performance and impacts of dams - presents a new framework for water and energy resources development - develops an agenda of seven strategic priorities with corresponding criteria and guidelines for future decision-making. Challenging our assumptions, the Commission sets before us the hard, rigorous and clear-eyed evidence of exactly why nations decide to build dams and how dams can affect human, plant and animal life, for better or for worse. Dams and Development: A New Framework for Decision-Making is vital reading on the future of dams as well as the changing development context where new voices, choices and options leave little room for a business-as-usual scenario.

A guide to help planners and engineers to the improvment of future water projects. The past century of global experience on water projects is presented as the basis for creating new approaches. First-hand analyses, including 35 case studies from 25 countries, portray the influence of politicians, biologists, engineers, computer models and physicians on the spectacular successes and failures of the builders of canals and dams. By drawing on this experience, the author outlines methods for assessing, predicting and preventing major water-associated diseases around large dams, canals and irrigation systems.

Asia's 48 countries have an estimated 1.757 billion urban population and 2.4 billion people in rural areas (or approximately 60 per cent of the global population). Divided into central, eastern, southern, south-eastern and western regions, the continent is also extremely heterogeneous in terms of water quality conditions. The policies and management practices vary significantly from one country to another, and even within one country, depending on specific economic, political, social, environmental, legal and institutional factors. In order to appreciate the complexities associated with water quality policy and management, it is important to acknowledge the multiplicity of interrelated and often conflicting events, issues, actors and interests, both within and outside the water sector that impact them. This complexity, alongside institutional inability for systematic and coordinated collaboration, are potent reasons as to why, in the second decade of the 21st century, formulation and implementation of efficient water quality management policies benefitting humankind and the environment have still not been achieved. The book was originally published as a special issue of the International Journal of Water Resources Development.
