Book Description
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.

Book Description
Agricultural water management is a vital practice in ensuring reduction, and environmental protection. After decades of successfully expanding irrigation and improving productivity, farmers and managers face an emerging crisis in the form of poorly performing irrigation schemes, slow modernization, declining investment, constrained water availability, and environmental degradation. More and better investments in agricultural water are needed. In response, the World Bank, in conjunction with many partner agencies, has compiled a selection of good experiences that can guide practitioners in the design of quality investments in agricultural water. The messages of 'Shaping the Future of Water for Agriculture: A Sourcebook for Investment in Agricultural Water Management' center around the key challenges to agricultural water management, specifically: - Building policies and incentives - Designing institutional reforms - Investing in irrigation systems improvement and modernization - Investing in groundwater irrigation - Investing in drainage and water quality management - Investing in water management in rainfed agriculture - Investing in agricultural water management in multipurpose operations - Coping with extreme climatic conditions - Assessing the social, economic, and environmental impacts of agricultural water investments 'Shaping the Future of Water for Agriculture' is an important resource for those interested and engaged in development with a focus on agricultural water.

Book Description
This open access book surveys the frontier of scientific river research and provides examples to guide management towards a sustainable future of riverine ecosystems. Principal structures and functions of the biogeosphere of rivers are explained; key threats are identified, and effective solutions for restoration and mitigation are provided. Rivers are among the most threatened ecosystems of the world. They increasingly suffer from pollution, water abstraction, river channelisation and damming. Fundamental knowledge of ecosystem structure and function is necessary to understand how human acitivities interfere with natural processes and which interventions are feasible to rectify this. Modern water legislation strives for sustainable water resource management and protection of important habitats and species. However, decision makers would benefit from more profound understanding of ecosystem degradation processes and of innovative methodologies and tools for efficient mitigation and restoration. The book provides best-practice examples of sustainable river management from on-site studies, European-wide analyses and case studies from other parts of the world. This book will be of interest to researchers in the field of aquatic ecology, river system functioning, conservation and restoration, to postgraduate students, to institutions involved in water management, and to water related industries.

Book Description
Dam assessment, by its very nature, is a complex undertaking. Many of the benefits and costs associated with dam development have quite different time streams. These benefits and costs are faced by different sectors and there are inter-relationships between sectors. The effects of dams are distributed across different spatial scales, from local to basin, to regional to national, and in some cases, to trans-national. To add to the complexity, while some of the impacts of the dam projects are direct , the others are indirect with the definition of what constitutes direct versus indirect impacts also varying. The aim of the present study has been to evaluate some of the above interactions, in particular the direct and indirect economic impacts of dams. The study ex-post evaluates the magnitude of multipliers, a measure of the total benefits (direct plus indirect) of the project in relation to its direct benefits, and assesses the distributional and poverty reduction impacts of dam projects. The four cases studied in the present book include three large projects Bhakra Dam System (India), Aswan High Dam (Egypt) and Sobradinho Dam (and the set of cascading reservoirs) (Brazil) and one small check dam Bunga (India). The present study should be seen as one of the numerous other steps that need to be taken to reach the goal of evaluating the full development impact of the dam projects. The aim here has been to highlight the relevance of one of the components of a full evaluation of dam projects that is often neglected, i.e., their indirect and induced economic impacts.

Book Description
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.

Book Description
This paper describes the potential impact on the economy of Pakistan of building the Diamer-Basha dam. An integrated system of economic and water simulation models is applied to Pakistan to analyze the economywide impacts of changes in water resources in the Indus river basin, focusing on agricultural and hydropower benefits provided by the Diamer-Basha dam under different climate scenarios. The model framework links separate economic and water models, drawing on the strengths of both approaches without having to compromise by specifying either a simplified treatment of water in an economic model or simplified economics in a water model. The model system is used to simulate the impact of economic growth and changes in water resources over the long run, focusing on agriculture and hydropower. The results of scenario analysis indicate that the Diamer-Basha dam would improve the resilience of Pakistan to adapt to climate shocks, providing increased hydropower capacity and enhanced ability to manage the water system to offset climate-induced variation in river flows.
