Book Limnology  Climatology and Paleoclimatology of the East African Lakes

Download or read book Limnology Climatology and Paleoclimatology of the East African Lakes written by A.Ivan Johnson and published by Routledge. This book was released on 2019-08-13 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Book East African Ecosystems and Their Conservation

Download or read book East African Ecosystems and Their Conservation written by T. R. McClanahan and published by Oxford University Press, USA. This book was released on 1996 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: East Africa is one of the most diverse and interesting tropical area on the planet. It is home not only to the last great megafaunal assemblage, but also to human populations with the highest growth rates. This book draws on the expertise of leading ecologists, each intimately familiar with a particular set of East African ecosystems, to provide the first in-depth and integrated account of the ecology, management, threats, and conservation of these diverse ecosystems. Summarizing the tremendous wealth of scientific research that has come out of East Africa in the last few decades, each chapter analyzes a given ecosystem type, taking the reader through the basics of its ecology, its historical use (and misuse) by humans, and its prospects for conservation. Throughout the book, linkages and similarities among ecosystems are emphasized, the historical and contemporary role of humans in shaping these ecosystems is considered, fundamental principles of ecology are considered, and interesting case studies are highlighted. Students and researchers in ecology, conservation biology, and environmental sciences will find this book useful in their work.

Book Operational and Environmental Consequences of Large Industrial Cooling Water Systems

Download or read book Operational and Environmental Consequences of Large Industrial Cooling Water Systems written by Sanjeevi Rajagopal and published by Springer Science & Business Media. This book was released on 2012-01-07 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of water for industrial purposes is of foremost importance. It is used as a coolant and industrial activities dealing with power generation, steel and iron, paper and pulp and oil require very large amounts of water. The industry, therefore, resorts to large scale abstraction of water from natural water bodies. This water is often treated with chemicals to combat operational problems like biofouling and corrosion. Such withdrawal and subsequent discharge of large amounts of water have the potential to impart significant impact on the recipient water body. The organisms drawn along with the cooling water, as well as those residing at the discharge zone, are subjected to a combination of mechanical, thermal and chemical stress on a continuous basis.

Download or read book The Niger River Basin written by Inger Andersen and published by World Bank Publications. This book was released on 2005-01-01 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Niger River Basin, home to 100 million people, is a vital yet complex asset for West and Central Africa. It is the continent's third largest river basin, traversing nine countries -Benin, Burkina Faso, Cameroon, Chad, C©þte d'Ivoire, Guinea, Mali, Niger, and Nigeria. The River embodies both these nations' livelihoods and their geopolitics. It is not simply water but rather an origin of identity, a route for migration and commerce, a source of conflict, and a catalyst for cooperation. Cooperation among decision-makers and users is crucial to address the threats to water resources. The Niger.

Book Health impacts of small reservoirs in Burkina Faso

Download or read book Health impacts of small reservoirs in Burkina Faso written by Eline Boelee and published by IWMI. This book was released on 2010-02-02 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Burkina Faso, at least 1,700 small reservoirs have been constructed, most of them during the last 30 years. Numerous and scattered, these beneficial multipurpose systems combine productive with domestic water uses. However, their environmental and health impacts remain insufficiently documented. This report combines data from different sources into syntheses and national maps, with a focus on water-related diseases. The mitigation of negative impacts requires an integrated approach to specifically identify the enhancing and limiting factors that influence environmental impacts and the transmission of diseases around reservoirs. Public awareness campaigns need to accompany the promotion of preventive and curative measures and the development of alternative water sources for domestic supply.

Book Eutrophication of Freshwaters

Download or read book Eutrophication of Freshwaters written by David Harper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication is a problem which became widely recognised by the scientific community in the 1940s and 1950s. It raised public concern, resulting in increased research effort and expenditure on management techniques through the 1960s and 1970s, recognised as a distinct problem of water pollution, though linked with the more gross effects of organic pollution. In the 1980s it became less fashionable - replaced in the public's eye and the politician's purse by newer problems such as acid rain. It remains however, one of the biggest and most widespread problems of fresh waters, particularly of lakes and an increasing problem for estuaries and coastal waters. It is one with which almost all water scientists and engineers in urbanised areas of the world have to cope. Technical methods for the reversal of eutrophication, such as nutrient removal, have been developed and applied successfully in some instances. They are not widespread however, and where they are feasible, they are often expensive and may be politically difficult to implement. In the last decade, attention has focussed upon less expensive lake manipula tion techniques, such as destratification and biomanipulation, which aim to minimise rather than elimininate the detrimental effects of eutrophication. These are becoming more widely applied. Prediction of the potential problems in lakes and catchments which have not yet suffered the full effects of eutrophication is now accurate enough to be of direct benefit to river basin management.
