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 Synopsis The ecology and management of African wetland vegetation by : Patrick Denny
Download or read book The ecology and management of African wetland vegetation written by Patrick Denny and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 355 pages. Available in PDF, EPUB and Kindle. 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 Synopsis Wetland Management and Sustainable Livelihoods in Africa by : Adrian Wood
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 Saline Lakes written by John M. Melack and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 317 pages. 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 Synopsis Insects and Human Life by : Brian Morris
Download or read book Insects and Human Life written by Brian Morris and published by Routledge. This book was released on 2020-05-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This pioneering book looks at the importance of insects to culture. While in the developed West a good deal of time and money may be spent trying to exterminate insects, in other cultures human-insect relations can be far more subtle and multi-faceted. Like animals, insects may be revered or reviled - and in some tribal communities insects may be the only source of food available. How people respond to, make use of, and relate to insects speaks volumes about their culture. In an effort to get to the bottom of our vexed relationship with the insect world, Brian Morris spent years in Malawi, a country where insects proliferate and people contend. In Malawi as in many tropical regions, insects have a profound impact on agriculture, the household, disease and medicine, and hence on oral literature, music, art, folklore, recreation and religion. Much of the complexity of human-insect relations rests on paradox: insects may represent the source of contagion, but they are also integral to many folk remedies for a wide range of illnesses. They may be at the root of catastrophic crop failure, but they can also be a form of sustenance.Weaving science with personal observations, Morris demonstrates a profound and intimate knowledge of virtually every aspect of human-insect relations. Not only is this book extraordinarily useful in terms of the more practical side of entomology, it also provides a wealth of information on the role of insects in cultural production. Malawian proverbs alone provide many such delightful examples - 'Bemberezi adziwa nyumba yake' ('The carpenter bee knows his own home'). This final volume in Morris' trilogy on Malawi's animal and insect worlds is certain to become a classic study of uncharted territory - the insect world that surrounds us and how we relate to it. Praise for The Power of Animals:Although based upon examination of a single culture, Morris incorporates ecological and anthropological concepts that expand this study of
Download or read book Malawi written by Philip Briggs and published by Bradt Travel Guides. This book was released on 2019-07-05 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Cartographies of Nature by : Maano Ramutsindela
Download or read book Cartographies of Nature written by Maano Ramutsindela and published by Cambridge Scholars Publishing. This book was released on 2014-06-19 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ascendancy of border studies in the last two decades or so, and the burgeoning work on nature and society neither drew attention to ecological theories of borders nor capitalised on nature as a useful avenue through which border research could be advanced. This volume fills this void by engaging with the following key questions: What insights can be drawn from species’ borders to broaden understandings of bordering? What sorts of borders are engendered by various types of conservation areas? What border stories does each of these areas tell us? What do conservation-related borders teach us about multiple lines that divide societies? Answers to these questions help researchers understand a typology of nature-related borders. The primary objectives of this volume are twofold. The first objective is to expand and deepen the links between nature conservation and border studies by bringing species’ borders into conversation with border studies, while at the same time paying attention to diverse conservation areas and conservation practices. The second objective is to highlight forms of borders associated with various types of conservation areas and the protection of certain types of natural resources. The manner in which nature conservation produces borders, and the forms those borders take, has the potential to enrich the conceptualisation of borders. The point of departure in this volume is that conservation practices produce feedback loops on social reality. Authors in the volume variously show that concerns with environmental protection and management offer possibilities for exploring, and even disrupting, borders within society and those between society and nature. Conservation areas in particular are crucial for a meaningful analysis of natures’ borders and the discourses and narratives related to them, and how such discourses influence conservation practice. This volume is an invaluable resource for research and upper-level courses on border studies, political ecology, conservation and biodiversity management, and environmental change and social impact.
