Available in PDF, EPUB and Kindle. Book excerpt: "If the wars of the last century were fought over oil, the wars of this century will be fought over water." -Ismail Serageldin, The World Bank The giant dams of today are the modern Pyramids, colossally expensive edifices that generate monumental amounts of electricity, irrigated water, and environmental and social disaster. With Deep Water, Jacques Leslie offers a searching account of the current crisis over dams and the world's water. An emerging master of long-form reportage, Leslie makes the crisis vivid through the stories of three distinctive figures: Medha Patkar, an Indian activist who opposes a dam that will displace thousands of people in western India; Thayer Scudder, an American anthropologist who studies the effects of giant dams on the peoples of southern Africa; and Don Blackmore, an Australian water manager who struggles to reverse the effects of drought so as to allow Australia to continue its march to California-like prosperity. Taking the reader to the sites of controversial dams, Leslie shows why dams are at once the hope of developing nations and a blight on their people and landscape. Deep Water is an incisive, beautifully written, and deeply disquieting report on a conflict that threatens to divide the world in the coming years.

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.

Book excerpt: 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.

Download or read book Dam Politics written by William Robert Lowry and published by Georgetown University Press. This book was released on 2003 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: The politics of building dams and levees and other structures are just part of the policies determining how American rivers are managed or mismanaged. America's well-being depends upon the health of those rivers and important decisions go beyond just dam-building or dam removal. American rivers are suffering from poor water quality, altered flows, and diminished natural habitat. Current efforts by policymakers to change the ways American rivers are managed range from the removal of dams to the simulation of seasonal flows to the restoration of habitat, all with varying degrees of success. Efforts to restore American rivers are clearly delineated by William Lowry in Dam Politics as he looks at how public policy and rivers interact, examines the physical differences in rivers that affect policies, and analyzes the political differences among the groups that use them. He argues that we are indeed moving into an era of restoration (defined in part as removing dams but also as restoring the water quality, seasonal flows, and natural habitat that existed before structural changes to the rivers), and seeks to understand the political circumstances that affect the degree of restoration. Lowry presents case studies of eight river restoration efforts, including dam removals on the Neuse and Kennebec rivers, simulation of seasonal flows on the Colorado river, and the failed attempt to restore salmon runs on the Snake river. He develops a typology of four different kinds of possible change--dependent on the parties involved and the physical complexity of the river--and then examines the cases using natural historical material along with dozens of interviews with key policymakers. Policy approaches such as conjunctive water management, adaptive management, alternative licensing processes, and water marketing are presented as possible ways of using our rivers more wisely. Dam Politics provides a useful and systematic account of how American waterways are managed and how current policies are changing. American rivers are literally the lifeblood of our nation. Lowry has written a lively and accessible book that makes it clear as a mountain stream that it matters deeply how those rivers are managed.

This book was released on 2006-02-15 with total page 1373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources stored by dams and reservoirs play an essential role in water resource management, hydropower and flood control. Where there is an extensive network of dam infrastructures, dams have made a major contribution to economic and social development, providing considerable storage capacity per capita. However, dams and reservoirs may also have an important social and environmental impact, and should be studied within the framework of integrated water resource management and sustainable development. Dams and Reservoirs, Societies and Environment in the 21st Century presents the latest research on the role played by dams and reservoirs in 21st century societies, in developed, emergent and developing countries. It analyses the viability of dams and suggests alternative solutions from a holistic perspective, considering the technical, economic, social and environmental aspects. Other issues covered include the social acceptability of dams, public involvement and dam awareness. The book covers subjects ranging from dam engineering, through the benefits and drawbacks of dams, to their social and environmental impact, and contains numerous case studies of the constructive contributions that reservoirs have made to water development and management. The book is a valuable resource for professional and dam engineers, water managers, governmental organizations and commercial enterprises responsible for dam development and management.

Download or read book Effects of Low head Dams on Habitat Structure Carbon and Nitrogen Allocation and Microbial Activity in Urban Rivers written by Lauren E. McGee and published by . This book was released on 2008 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: My study objective was to assess how low-head dams impact urban riverine structure and function. I hypothesized that lowhead dam reservoirs would be retentive of materials. I conducted this study in five paired reservoir-reference sites in central Ohio during spring, summer, and autumn 2007. Two-factor block ANOVAs were used to assess differences between reservoir and reference reaches. Most hypotheses were confirmed. Reservoirs had slower water velocities, greater water depths, more fine-sized sediment, greater C and N in sediment, and greater rates of denitrification than reference reaches. C and N in waters, however, were similar in reservoirs and reference reaches. Although water velocities were reduced in reservoirs, water flow was not correlated with C and N in sediments. This suggests that reduced water flows in urban rivers may not be strong enough to lead to the removal of materials from water. Urbanization could play a larger role in impacting ecosystem function.

Book excerpt: Scholarly Essay from the year 2013 in the subject Environmental Sciences, grade: 10.0, Indian Institute of Technology, Delhi, language: English, abstract: According to WWF: Worldwide the total amount of water stored in dams is 3-6 times more than that contained in rivers. The wetlands area during the 20th century has decreased by over 50%. Out of the 10,000 recorded freshwater species more than 20% have either become extinct, threatened or endangered in recent times. These facts are enough to justify the tremendous impact on environment dams are having. Large scale projects like dams are often floated as important and necessary means of economic development. But this development comes at some or the other cost. Cost to the environment, development and society. So what are dams really for? Water supply for the general public for domestic uses as well as irrigation which is imperative for our agrarian Indian society. Hydroelectric power generation. India is the 7th largest producer of hydroelectric power with 114 Tetra-watt hours. It produces 3.3% of the world total. Dams impede the turbulent and sudden flow of water to prevent floods. Well that is what they are for and granted many of them achieve the above given purposes but they are subject to widespread criticism and debate. Several vehement national and international movements have brought into light the severe problems associated with them. Dams have been criticized for disturbing natural water flows, affecting deposits of nutrients as well as lifecycles of species that depend on freshwater habitat. Reductions in water quantities can increase salinity and make the water unusable for drinking and irrigation. The transport of sediments that are crucial for natural cycles is also affected. This may cause flood risks, lower groundwater tables and in turn affect entire ecosystems. With that said we must point out that dams do not always have a negative impact on habitats. E.g. once reservoirs beco

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.
