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.

Book excerpt: Interest in the biology of African 'wetlands' was initiated in the last century with the hypothesis that Lake Tanganyika was once part of a Jurassic sea, and was furthered by Cunnington's expedition at the beginning of this century which proved that it was not. In the late 1920's, ecological studies, encouraged by the growing importance of inland fisheries, were started hy British, French and Belgian biologists. Some twenty years later several government limnological research centres and fishery departments were established in tropical Africa, and scientific progress was accelerated. Scientific collaboration between the regions south of the Sahara was started formally in 1951 by the Scientific Council for Africa and stimulated by the International Biological Programme (1964-74) with its emphasis on biological productivity. Some of its interests were takcn on by SCOPE which recently selected continental wetlands as a Special Project; hence this book. The five authors, with-Patrick Denny as editor, have made a very valuable contribution both to science and to thc management of Africa's natural rcsourccs: thcy have filled a gap in the synthesis of knowledge about Africa's environments which is long overdue. The term 'wetland' is used today in several different contexts. For this purpose, it excludes the seas and large open inland waters. which are too deep for rooted plants, but includes the huge areas of floodplains and dambos which may change seasonally from standing water to very dry lands.

Book excerpt: The Lake Chilwa Basin Climate Change Adaptation Programme was a seven-year research and development programme in Malawi that concluded in March 2017. The programme was designed to protect the livelihoods of the population and enhance resilience of the natural resource base upon which it depends. The Lake Chilwa Basin is an important wetland ecosystem which is a designated Ramsar Site under the Ramsar Wetland Convention and a Man and Biosphere Reserve designated by UNESCO. This book provides a review of the research and programme interventions done based on the ecosystem approach (EA), a strategy for the integrated management of land, water and living resources. This is designed to promote biodiversity conservation and sustainable use in an equitable way in its implementation of mitigation and climate change adaptation interventions. It is shown how: local and district institutions were strengthened to better manage natural resources and build resilience to climate change; cross-basin and cross-sector natural resource management and planning for climate change throughout the Basin were built; household and enterprise adaptive capacity in Basin hotspots was built; and improved forest management and governance contributed in mitigating the effects of climate change. The study followed all the twelve key EA principles with involvement of all key stakeholders. It is one of the first programmes to apply EA on such a wide temporal and spatial scale and provides key lessons to be learned for the protection of other fragile ecosystems in an era of climate change.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Limnological research on saline lakes is practiced by a growing cadre of scientists active worldwide in a diversity of disciplines. Every three years since 1979, an international symposium on inland saline waters has served to strengthen and expand the scope of the studies. Promising areas for further research especially well suited to saline lakes include the comparative physiology of adaptation to osmotic stresses, the role of microbial and protozoan communities in nutrient dynamics and biotic interactions in ecosystems with few species. The Third International Symposium on Inland Saline Lakes was held at the University of Nairobi, Nairobi, Kenya, under the auspices of the Societas Internationalis Limnologiae (SIL). The symposium was sponsored by and received financial or other support from the U.S. National Science Foundation (International Program), United Nations Environment Program, University of California, Santa Barbara, and University of Nairobi. The proceedings occurred for three days (28-31 August, 1985) and were attended by 33 scientists from 14 countries (see list of Participants). On the day prior to the first formal session an afternoon trip to Lake Magadi and salt works was held. The tribulations of this excursion served to acquaint the participants with each other and with the realities of exploring the African bush. A three day post-congress expedition to the rift valley included visits to spectacular saline lakes such as Nakuru and Bogoria. Much of the meeting's and excursion's success is owed to the efforts of the local organizer, Dr. Stephen G.

Book excerpt: This publication contains reports of ten case studies of freshwater fisheries in southern Africa which were conducted in five medium-sized lakes in the Democratic Republic of the Congo, Malawi, Zambia and Zimbabwe.
