Available in PDF, EPUB and Kindle. Book excerpt: Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.

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 Wetland Management and Sustainable Livelihoods in Africa written by Adrian Wood and published by Routledge. This book was released on 2013-06-19 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors argue for a paradigm shift in the way African wetlands are considered. Current policies and wetland management are too frequently underpinned by a perspective that views agriculture simply as a threat and disregards its important contribution to livelihoods. In rural areas where people are entrenched in poverty, wetlands (in particular wetland agriculture) have a critical role to play in supporting and developing peoples' livelihoods. Furthermore, as populations rise and climate change takes grip they will be increasingly important. The authors argue that an approach to wetland management that is much more people focused is required. That is an approach that instead of being concerned primarily with environmental outcomes is centred on livelihood outcomes supported by the sustainable use of natural wetland resources. The authors stress the need for Integrated Water Resource Management and landscape approaches to ensure sustainable use of wetlands throughout a river catchment and the need for wetland management interventions to engage with a wide range of stakeholders. They also assess the feasibility of creating incentives and value in wetlands to support sustainable use. Drawing on nine empirical case studies, this book highlights the different ways in which sustainable use of wetlands has been sought, each case focusing on specific issues about wetlands, agriculture and livelihoods.

Download or read book Marketing and Consumption of Fish in Eastern and Southern Africa written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 1993 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seven country case studies of fish marketing and distribution patterns are presented in this collection. Country studies of Burundi, Lesotho, Malawi, Tanzania, Uganda, Zambia, and Zimbabwe were prepared in accordance with a recommendation of the Technical Consultation on Aquaculture and Human Nutrition (Maseru, Lesotho, 5-8 June 1989). The selected countries represent a considerable range of circumstances in terms of such dimensions as territorial extent, access to marine or freshwater resources, domestic production capcities, and traditions of fisheries and fish consumption. An introductory overview chapter provides a summary account based on the format used for each of the case presentations, and sets out general recommendations for further development action on a region-wide basis.
Download or read book Freshwater small pelagic fish and their fisheries in the major African lakes and reservoirs in relation to food security and nutrition written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2019-02-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small pelagic fish species found in lakes and introduced to reservoirs dominate by volume and contribute some of the most important inland fisheries in Africa with steadily increasing catches and additional potential. This circular reviews the status and importance of the pelagic fish and fisheries, together with small fish in general, for sustainable and healthy livelihoods in Africa. It reviews the biology and biological production of the most important pelagic species in lakes and reservoirs as well as the impacts of environmental and climatic variation on the stocks of these species. It examines and discuss the various capture techniques together with potential of improvements in the fisheries and associated processing and national and regional trade within Africa. The knowledge generated by the circular will be useful for policy makers and development practitioners to design and implement more effective policies, strategies and programs that will contribute to reducing the food insecurity and conflicts that currently affect the people in sub-Saharan Africa.

Download or read book Africa s Lakes written by and published by UNEP/Earthprint. This book was released on 2006 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prepared as part of UNEP's contribution to the 11th World Lakes Conference (held in Nairobi, Kenya in November 2005), this publication examines the environmental changes taking place to Africa's lakes by analysing ground photographs, current and historical satellite images and scientific evidence. Changes highlighted include the rapid shrinking of Lake Songor in Ghana, partly as a result of intensive salt production, and the extraordinary changes in the Zambezi river system as a result of the building of the Cabora Basa dam site. Other impacts, some natural and some human-made and which can only be truly appreciated from space, include the extensive deforestation around Lake Nakuru in Kenya, and the falling water levels of Lake Victoria which is now about a metre lower than it was in the early 1990s. The analysis recognises the importance of Africa's lakes as a source of livelihoods for many local communities, their contribution to the socio-economic development of the continent and the need for the sustainable management of these resources in order to help overcome poverty and meet internationally agreed development goals by 2015.
Download or read book Building Climate Resilience through Virtual Water and Nexus Thinking in the Southern African Development Community written by Anna Entholzner and published by Springer. This book was released on 2016-05-23 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book puts the spotlight on Southern Africa, presenting a cutting-edge concept never previously explored in the context of climate change and putting forward arguments for regional integration and cooperation. The Climate Resilient Infrastructure Development Facility (CRIDF) is the new water infrastructure program of the UK Department for International Development (DFID) for Southern Africa. The CRIDF promotes the establishment of small to medium-scale infrastructure across the Southern African Development Community (SADC) through technical assistance aimed at developing sustainable pro-poor projects, while also facilitating access to the financial resources needed to deliver said infrastructure. Further, it focuses on regional water resource management goals and basin plans, as well as on building climate resilience for the beneficiary communities. The Facility’s Virtual Water and Nexus Project works to improve regional peace dividends by translating the Nexus concept into national and regional policies; it ultimately promotes sovereign security through greater regional integration across the water, food and energy sectors, while taking into account potential benefits in connection with carbon sequestration and emission mitigation.
