Book excerpt: The conventional approach to river protection has focused on water quality and maintaining some "minimum" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance. Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

Download or read book Environmental Flows written by Angela Arthington and published by Univ of California Press. This book was released on 2012-10-15 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental Flows describes the timing, quality, and quantity of water flows required to sustain freshwater and estuarine ecosystems and the human well-being and livelihoods that depend upon them. It answers crucial questions about the flow of water within and between different kinds of ecosystems. What happens when the flow or the availability of water is curtailed or diverted, either naturally or by human activity? How will climate change alter the availability of water and impact aquatic ecosystems? Methodological developments from the simplest hydrological formulas to large-scale frameworks that inform water management make this book a must-read for water managers and freshwater and estuarine ecologists contending with ever-changing conditions influencing the flow of water.
Download or read book Inland Waters of Southern Africa An Ecological Perspective written by B.R. Allanson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Limnology - the study of inland waters - had its genesis in Europe about the turn of the century. The studies of Fore1 on Lake Geneva were of seminal value at this time. It prospered under the early guidance of Thienemann, Naumann and Wesenberg-Lund in Europe and, soon transplanted, of Birge and Juday in North America (to name just a few early spirits). Now, liminology is a respectable scientific discipline taught at many universities, and limnologists are recognized as important contributors to our understanding of how this fragile spaceship functions. All this acknowledged, it must also be acknowledged that limnology is not yet a globally comprehensive science. To be sure, much is known about globally applicable processes, and the structural elements of aquatic ecosystems worldwide, but limnological emphases, interests and concerns remain essentially European and North American in balance. Much is known about lakes and rivers in less than one fifth of the world's land area (northern temperature regions); rather little is known about inland waters elsewhere.

Download or read book Management and Ecology of Freshwater Plants written by Joseph Caffrey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate management of aquatic plants in rivers and canals, lakes and reservoirs, and drainage channels and urban waterways. This management must be based on a sound knowledge of the ecology of freshwater plants, their distribution and the different forms of control available including chemical, physical, biological and biomanipulation. This series of papers from over 20 different countries was generated from the highly successful European Weed Research Society symposia on aquatic plant management, this being the ninth. The contributions provide a valuable insight into the complexities involved in managing aquatic systems, discuss state-of-the-art control techniques such as biomanipulation using fish and waterfowl and the use of straw, and deal with patterns of regrowth and recovery post-management. Careful consideration is given to the use of chemicals, a practice which has come under scrutiny in recent years. Underpinning the development of such control techniques is a growing body of knowledge relating to the biology and ecology of water plants, including growth responses under different trophic conditions, the impact of pollution, and aspects of photosynthesis. The authorship of the papers represents the collective wisdom of leading scientists and experts from fisheries agencies, river authorities, nature conservation agencies, the agrochemical industry and both governmental and non-governmental organisations.
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 Use of a hydrological model for environmental management of the Usangu Wetlands Tanzania written by Kashaigili, J. J., McCartney, Matthew, Mahoo, H. F., Lankford, B. A., Mbilinyi, B. P., Yawson, D. K., Tumbo, S. D. and published by IWMI. This book was released on 2006 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the findings of a study to assess changes to flows into, and downstream of, the Usangu Wetlands, located in the headwaters of the Great Ruaha River, Tanzania. Hydrological data, in conjunction with remote sensing techniques, were used to provide insights into changes that have occurred to the Eastern Wetland. Results indicate that, between 1958 and 2004, inflows to the wetland declined by about 70 percent in the dry season months (July to November) as a consequence of increased human withdrawals, primarily for irrigation.
Download or read book Transboundary Water Management written by Anton Earle and published by Routledge. This book was released on 2013-10-18 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The management of water resources across boundaries, whether sub-national or international, is one of the most difficult challenges facing water managers today. The upstream exploitation or diversion of groundwater or rivers can have devastating consequences for those living downstream, and transboundary rivers can provide a source of conflict between nations or states, particularly where water resources are scarce. Similarly, water based-pollution can spread across borders and create disputes and a need for sound governance. This book is the first to bring together in a concise and accessible way all of the main topics to be considered when managing transboundary waters. It will raise the awareness of practitioners of the various issues needed to be taken into account when making water management decisions and provide a practically-based overview for advanced students. The authors show clearly how vital it is to cooperate effectively over the management of shared waters to unlock their contribution to regional sustainable development. The book is largely based on a long-running and tested international training programme, run by the Stockholm International Water Institute and Ramboll Natura, and supported by the Swedish International Development Co-operation Agency (Sida), where the respective authors have presented modules on the programmes. It addresses issues not only of conflict, but also of managing power asymmetries, benefit-sharing, stakeholder participation, international water law, environmental water requirements and regional development. It will be particularly useful for those with a background in hydrology or engineering who wish to broaden their management skills.

Download or read book Ecological Changes in the Zambezi River Basin written by Mzime Ndebele-Murisa and published by African Books Collective. This book was released on 2021-01-11 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an analysis of the ecological conditions and ecosystem goods and services of the Zambezi River Basin (ZRB), the fourth largest river in Africa. Various environmental and anthropogenic factors; inclusive of climate, environmental flows, hydrology, morphology, pollution and land use changes among others and their interactions are considered as drivers of the river ecosystems. The impacts of these drivers on aquatic biota, river ecological integrity, and the livelihoods of surrounding communities are analysed within the socio-economic-policy context. The book goes beyond the usual inventories and basic research by using the comparative research method (CRM) in a trans-disciplinary manner. This CRM analytical approach in this book seeks to interrogate the differences or similarities in socio-economic systems, livelihoods, ecological systems, ecosystem goods and services, their usage and management under the seemingly different cultural, socio-economic conditions expected across boarders that are within the ZRB. The multidisciplinary approach also connects the typical ecological research with social dimensions in a holistic manner. The book therefore, provides empirical and research based evidence to support strategic planning and policy development in the wake of ecological changes that nations and indeed regions such as the ZRB are grappling with while seeking to sustainably manage precious river systems.
