Download or read book The East African Great Lakes Limnology Palaeolimnology and Biodiversity written by Eric O. Odada and published by Springer Science & Business Media. This book was released on 2006-03-09 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Second International Symposium on the East African Lakes was held from 10-15 January 2000 at Club Makokola on the southern shore of Lake Malawi. The symposium was organized by the International Decade for the East African Lakes (IDEAL), a research consortium of African, European and North American scientists interested in promoting the investigations of African Great Lakes as archives of environmental and climatic dynamics. Over one hundred African, European and North American scientists with special expertise in the tropical lakes participated in the symposium which featured compelling presentations on the limnology, climatology, palaeoclimatology and biodiversity of the East African Lakes. It is their papers that comprise this book. The large lakes of East Africa are important natural resources that are heavily utilized by their bordering countries for transportation, water supply, fisheries, waste disposal, recreation and tourism. The lakes are unique in many ways: they are sensitive to climatic change and their circulation dynamics, water-column chemistry and biological complexity differ significantly from large lakes at higher latitudes; they have long, continuous, high resolution records of past climatic change; and they have rich and diverse populations of endemic organisms. These unique properties and the significance of the palaeolimnological records demand and attract research interest from around the world.

This book was released on 2019-08-13 with total page 679 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.

Download or read book Aquatic Biodiversity II written by H. Segers and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.
Download or read book Environmental Change and Response in East African Lakes written by J.T. Lehman and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book was born at the June 1996 meeting of the IDEAL Steering Committee in Milwaukee, Wisconsin. We had just completed a successful and stimulating special symposium during the annual meeting of the American Society for Limnology and Oceanography, and enthusiasm was running high for the production of a volume that could assemble in one place the scientific findings that were starting to emerge from East Africa. IDEAL, an International Decade for the East African Lakes, had ended one round of field investigations, many of which had been centered on Lake Victoria. As the climatologists, geologists, paleolimnologists, and biologists displayed their results and debated interpretations, it appeared that some paradigms were shifting, and that new explanations of climate history and modem processes were taking shape. The Steering Committee endorsed the production of a volume that would draw together the different research results that were emerging and which would be representative of the scope of science issues that exist within IDEAL. This book follows in the spirit of The Limnology, Climatology, and Paleoclimatology of the East African Lakes, published in 1996, but has a somewhat different purpose. The previous publication also included original science results, but it was conceived to review the state of knowledge, identify critical problems, and point to new paths of inquiry. It accompanied the development of our first Science and Implementation Plan for the East African Lakes.

Download or read book Soda Lakes of East Africa written by Michael Schagerl and published by Springer. This book was released on 2016-08-16 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the alkaline-saline lakes of East Africa, which include the world-famous “flamingo lakes”. It covers the full range of issues, from the lakes’ origin and history, life in and around these unique water bodies, to utilization, threats and management considerations. The authors, all of whom are leading international experts, summarize research done so far, highlight new and important findings, and provide future outlooks. The book is divided into three main sections: “Genesis, physics and chemistry” tackles lake development and the astounding physico-chemistry of the lakes. “Organisms and ecology” presents information about the many lake inhabitants, their interactions and adaptations to the extreme living conditions. “Utilization, management and perspectives” addresses threats such as lake exploitation and pollution, but also considers potential uses. This book will be particularly relevant to researchers and lecturers in the field of limnology and aquatic ecology, but is also designed to attract all those interested in nature and life on our planet.
Download or read book The Nile written by Henri J. Dumont and published by Springer Science & Business Media. This book was released on 2009-05-06 with total page 819 pages. Available in PDF, EPUB and Kindle. Book excerpt: What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.

This book was released on 2004-12-03 with total page 653 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on two complementary time-scales, the Holocene (approximately the last 11,500 years) and the last glacial-interglacial cycle (approximately the last 130,000 years) to synthesize evidence of climate variability at the regional and continental scale across Europe and Africa. This is the first examination of historical climate variations at such a scale, and thus sets a benchmark for future research.

Download or read book A History of the Water Hyacinth in Africa written by Jeremiah Mutio Kitunda and published by Lexington Books. This book was released on 2017-11-17 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans and animals are not the only creatures that migrate. Plants also do. This book is a comprehensive and analytical account of the migration of an Old World plant, water hyacinth (also known to botanists as Eichhornia Crassipes) from the Amazon Basin and surrounding areas to Africa through human agency from about 1800 to the present. As an integrative work, which benefits from methodologies and conceptual approaches drawn from limnology, botany, biology, geography, history, ecology and other social sciences and humanities, the book further explores the political, economic, and ecological consequences of the spread of water hyacinth from its native habitat through European botanical gardens to Africa rivers, lakes, dams, and wetlands. In part, as a narrative of Western tinkering with African ecologies gone awry, the study has strong lessons for environmental historians, and social scientists as well as contemporary foundations, aid workers, development experts and African governments. Although it may appear to be a micro-history of a single plant, water hyacinth, it illuminates broader issues in the history of the modern environment in Africa and similar studies worldwide. This study is primarily rooted on the histories of colonialism, bioinvasion, environmental realities and experiences in Africa. The highly visible pathways of hyacinth’s spread across international frontiers along watercourses and communication networks means that not only is this a trans-boundary environmental affair, but one which directly involves bilateral relations between African states.

Download or read book Climate Change and Water Resources in Africa written by Salif Diop and published by Springer Nature. This book was released on 2021-02-15 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this book is on the key water-related vulnerabilities to climate change in Africa, particularly in its most vulnerable areas, exploring potential management responses to such vulnerabilities. The African countries are particularly exposed and vulnerable to the negative impacts of climate change, with important impacts on water resources and hydrological systems, water availability, water resource management and sea level variations. Already, under various anthropogenic pressures, the status of water resources in Africa has been changing over the past decades, with decreasing water quality, falling groundwater levels, and variability in rainfall, both in terms of timing and intensity. Climate change will further accelerate the rate of change, affecting the ability of people and societies to respond in a timely manner. It is clear that there is no quick fix to the pressures imposed on water resources by climate change. Increasing the resilience of ecosystems and communities to extreme events such as flooding and drought, and integrating climate change risks and opportunities into development decision-making is indeed a key challenge, as much a technical climate-change one, as a political and developmental challenge. The book, in this regard, intends to contribute to the debate around climate change in relation to water resources management in Africa, and in particular inform policy decisions and actions that will improve governments’ and communities’ ability to manage the challenges of climate change and variability in relation to the aquatic ecosystems that they depend on. The knowledge collected in this book will benefit policy makers, researchers, as well as other stakeholders.

Download or read book Lake Kivu written by Jean-Pierre Descy and published by Springer Science & Business Media. This book was released on 2012-05-25 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the heart of Africa, a unique lake attracts the attention of scientists since the beginning of the 20th century. At the foot of the Virunga volcano chain, Lake Kivu harbors a vast amount of dissolved carbon dioxide and methane, making this lake the most dangerous lake on Earth. But the lake furnishes also many goods and services for surrounding populations and may soon become the most important energy supplier in the area. At the beginning of gas exploitation, the time has come for gathering the large amount of scientific information acquired during past and present research on Lake Kivu. The eleven chapters cover many aspects of the physics, geochemistry and biology of the lake, with a particular focus on the unique physical and geochemical features of the water column and on the ecological functioning of the surface waters. The impacts of the introduced fish species and the potential impacts of methane exploitation are also summarized. This multi-disciplinary book may also be used as an introduction to the limnology and biogeochemistry of large tropical lakes, as it covers various aspects of the physics, geochemistry, biology and ecology of the African Great Rift lakes.
