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.
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.
Download or read book Environmental Flow Assessment written by John G. Williams and published by John Wiley & Sons. This book was released on 2019-06-10 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment. Describes historical and recent trends in environmental flow assessment Directly addresses practical difficulties with applying a scientifically informed approach in contentious circumstances Serves as an effective introduction to the relevant literature, with many references to articles in related scientific fields Pays close attention to statistical issues such as sampling, estimation of statistical uncertainty, and model selection Includes recommendations for methods and approaches Examines how methods have been tested in the past and shows how they should be tested today and in the future Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.

Download or read book The Large Dam Dilemma written by Pu Wang and published by Springer Science & Business Media. This book was released on 2013-10-18 with total page 112 pages. 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.

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.
