Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Impacts of Large Dams A Global Assessment written by Cecilia Tortajada and published by Springer Science & Business Media. This book was released on 2012-02-02 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Large dam construction has significant environmental and social impacts at different scales. As the largest developing country in the world, China has built about half of the world’s large dams, and more are expected to be built over the next two decades to meet the country’s rapidly growing demand for energy. This book summarizes and updates information about the history, distribution, functions, and impacts of large dams, both globally and at China’s national level. It then addresses the environmental and social-economic impacts of large dams in China with particular emphasis on the impacts of large dams on relocated people and associated compensation policies. Lastly, it introduces an integrated ecological and socio-economic study conducted in areas affected by dams along the Upper Mekong River, China. This book has the following three goals. The first goal is to summarize and update information on large dams globally and at China’s national level (Ch. 2). We examine large dam problems from different perspectives, ranging from their spatial and temporal distributions and their environmental and social impacts, to discussions and debates centered on them. We also incorporate the results of an empirical investigation of the environmental and socio-economic impacts of large dams on the Upper Mekong River, China, and draw conclusions out of the analysis (Chs.3 & 4). Our second goal is to provide an analysis framework to help understand the environmental and social-economic impacts of dam construction and the resulting environmental degradations and social inequities at different scales (Chs.3 & 4), as well as to offer recommendations for mitigating these impacts within China’s socio-political context (Ch. 5). The significant environmental effects resulting from dam construction include damage to ecological integrity and loss of biological diversity. The most significant social consequences brought by dam projects are their negative impacts on relocated people. Our analysis framework provides approaches to help comprehensively understand these impacts. Our third goal is to provide clues and suggestions for further studies of large dam problems both globally and in China (Ch. 5). The construction of large dams is proceeding rapidly in different parts of the world despite the heated debates on whether they should be built at all. The decision-making process related to building large dams involves considerations of economic viability, environmental sustainability, and social equity. Therefore, interdisciplinary collaborations are required in large dam research and development projects in order to reconcile the interests of different stakeholders and avoid harming ecosystems, biodiversity, and human welfare. Overall, we hope our book facilitates future examinations of large dams by providing summaries of existing data and research related to large dams, and offering a framework for better understanding and analyzing their environmental and social impacts.

Download or read book Economic Evaluation of the Diamer Basha Dam written by Robinson, Sherman and published by Intl Food Policy Res Inst. This book was released on with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Dams and Development written by World Commission on Dams and published by Routledge. This book was released on 2016-05-13 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Riverine Ecosystem Management written by Stefan Schmutz and published by Springer. This book was released on 2018-05-08 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Grand Ethiopian Renaissance Dam (GERD) will not only be Africa’s largest dam, but it is also essential for future cooperation and development in the Nile River Basin and East African region. This book, after setting out basin-level legal and policy successes and failures of managing and sharing Nile waters, articulates the opportunities and challenges surrounding the GERD through multiple disciplinary lenses. It sets out its possibilities as a basis for a new era of cooperation, its regional and global implications, the benefits of cooperation and coordination in dam filling, and the need for participatory and transparent decision making. By applying law, political science and hydrology to sharing water resources in general and to large-scale dam building, filling and operating in particular, it offers concrete qualitative and quantitative options that are essential to promote cooperation and coordination in utilising and preserving Nile waters. The book incorporates the economic dimension and draws on recent developments including: the signing of a legally binding contract by Egypt, Ethiopia and Sudan to carry out an impact assessment study; the possibility that the GERD might be partially operational very soon, the completion of transmission lines from GERD to Addis Ababa; and the announcement of Sudan to commence construction of transmission lines from GERD to its main cities. The implications of these are assessed and lessons learned for transboundary water cooperation and conflict management.
