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.

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.

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.

This new eighth edition of Bradt's Malawi remains the only standalone practical guidebook to this magical East African destination, long known as the 'warm heart of Africa' (and the first country outside Denmark to have a Carlsberg brewery). Malawi is a small country with a big lake - accounting for around a third of its territory - and a big welcome. Written by Philip Briggs, arguably the world's most experienced guidebook author, this new edition benefits from a thorough country-wide update of all the practical information, with the addition of significant new game park accommodation. Dedicated chapters on background information, health and flora and fauna are complemented by a 19-chapter breakdown of the country and 37 maps, making this an ideal companion for backpackers, over-landers, wildlife spotters, birdwatchers and other outdoor enthusiasts. Included in the guide are the many outstanding adventure opportunities: kayaking on the vast lake amongst dug-out canoes; hikes from tea estates up to the heights Mount Mulanje; and watching the 'big five' animals in wonderful natural surroundings. There's also a resurgent music scene, intriguing monuments built by former colonisers and compelling village culture to discover. With the reintroduction of species including lions - and the recent translocation of large numbers of elephants to Nkhotakota Wildlife Reserve - Malawi is a wildlife destination to savour. From luxury camps to local guesthouses, from rhino trekking to cycle tours and from crafts to cultural tourism, Bradt's Malawi covers every aspect of your trip.
