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.
Book Synopsis Fragmentation of Natural Resources Management by : Lindah Mhlanga
Download or read book Fragmentation of Natural Resources Management written by Lindah Mhlanga and published by LIT Verlag Münster. This book was released on 2014 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a result of the Defragmenting African Resources Management (DARMA) Project. Lake Kariba - located along the border between Zambia and Zimbabwe - and its environs are a complex transboundary ecosystem with multiple, competing, and often contested resource uses. The book describes the current sectoral approach to natural resource management, the interconnections, and the need to adopt an ecosystem approach. It will be essential reading for students, researchers, academics, and managers in the environmental and natural resources sectors interested in advancing the ecosystems approach to the management of commons in general, and Southern Africa in particular.

Book Synopsis Inland Waters of Southern Africa: An Ecological Perspective by : B.R. Allanson
Download or read book Inland Waters of Southern Africa: An Ecological Perspective written by B.R. Allanson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: Limnology - the study of inland waters - had its genesis in Europe about the turn of the century. The studies of Fore1 on Lake Geneva were of seminal value at this time. It prospered under the early guidance of Thienemann, Naumann and Wesenberg-Lund in Europe and, soon transplanted, of Birge and Juday in North America (to name just a few early spirits). Now, liminology is a respectable scientific discipline taught at many universities, and limnologists are recognized as important contributors to our understanding of how this fragile spaceship functions. All this acknowledged, it must also be acknowledged that limnology is not yet a globally comprehensive science. To be sure, much is known about globally applicable processes, and the structural elements of aquatic ecosystems worldwide, but limnological emphases, interests and concerns remain essentially European and North American in balance. Much is known about lakes and rivers in less than one fifth of the world's land area (northern temperature regions); rather little is known about inland waters elsewhere.

Book Synopsis African fly-fishing handbook by : Bill Hansford-Steele
Download or read book African fly-fishing handbook written by Bill Hansford-Steele and published by Penguin Random House South Africa. This book was released on 2013-03-27 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fly-fishing in all its forms is the fastes-growing participatory field sport in the world. Whether you’re hoping to catch trout, tigerfish, yellowfish or queenfish, there is little to match the sheer joy of fishing with a fly rod. Whether you’re standing waist-deep in a raging river estuary fishing the saltwater, or wading slowly into the calm waters of an inland lake, the thrill of casting a perfect line is unmatched. Africa is one of the world’s most exciting fly-fishing destinations. Dedicated fly-fishers can be found casting their lines all over the continent – in steaming tropical rivers, in the vast lakes of the Great Rift Valley, in mountain streams, on golden beaches and in turbulent estuaries. Africa offers everything from well-fished and managed rivers and dams of South Africa and Kenya, to relatively unexposed and unknown destinations like the Bale Mountains in Ethiopia and the coastline of Madagascar. This completely revised, updated and full-colour edition of the African Fly-Fishing Handbook covers all aspects of fly-fishing on the African continent, and includes chapters on when and where to fly-fish in Africa, how to get started and what equipment to buy, casting and retrieving techniques, tactics and strategies, fresh- and saltwater fish, yellowfish, fish food forms and winning fly patterns. The most comprehensive book of its kind, it will be indispensable to both seasoned fly-fishers and those just starting out.
Book Synopsis Freshwater Fisheries Ecology by : John F. Craig
Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

This book was released on 2023-04-17 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book highlights the potential and actual contributions of the sustainable management and utilization of indigenous biological resources and environment for the development of Africa. The book centers on documenting current trends and issues in the field of resource use and conservation with the view of emphasizing their benefits to the pursuit of development within the region. By documenting the array of natural resources and environment in Africa, this book addresses the topical knowledge and understanding gaps that characterize conservation (rationale for sustainable resource exploration), utilization patterns, and conservation challenges including policy status, environmental threats, impacts of tourism, reduction in food resources, etc., and their effects on the sustainable development of Africa. Through an integrated approach, the book focuses on below and above-ground biological resources and the diverse scales of environment that characterize Africa. This collection of works is very helpful for natural and social scientists, policymakers, strategists, researchers, government and non-government organizations, biodiversity and environmental managers, climate change scientists, practitioners, activists, conservationists, academics, ecologists, undergraduate and postgraduate students, and others who want to learn about and understand the best way to use and protect Africa's resources and heritage sustainably.

Book Synopsis Biogeography and Ecology of Southern Africa by : Marinus J.A. Werger
Download or read book Biogeography and Ecology of Southern Africa written by Marinus J.A. Werger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Africa is certainly not a naturally bounded area so that there are several possibilities for delineating it and concepts about its extent. Wellington* discussed the various possibilities for delineation and suggested that one line stands out more clearly and definitely as a physical boundary than any other, namely the South Equatorial Divide, the watershed between the ZaIre, Cuanza and Rufiji Rivers on the one hand and the Z ambezi, Cunene and Rovuma Rivers on the other. This South Equatorial Divide is indeed a major line of separation for some organisms and is also applicable in a certain geographical sense, though it does not possess the slightest significance for many other groups of organisms, ecosystems or geographical and physical features of Africa. The placing of the northern boundary of southern Africa differs in fact strongly per scientific dis cipline and is also influenced by practical considerations regarding the possibilities of scientific work as subordinate to certain political realities and historically grown traditions. This is illustrated, for example, in such works as the Flora of Southern Africa, where the northern boundary of the area is conceived as the northern and eastern political boundaries of South West Africa, South Africa and Swaziland. Botswana, traditionally included in the area covered by the Flora Zambesiaca, thus forms a large wedge in 'Southern Africa'.

Book Synopsis Cyprinid Fishes by : Ian J. Winfield
Download or read book Cyprinid Fishes written by Ian J. Winfield and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range ofbiological adaptations to diverse habitats has evolved. As weIl as living in the conventional habitats of lakes. ponds. rivers. rock pools and the open sea. fish have solved the problems of life in deserts. in the deep sea. in the cold Antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations. we find the most impressive specializations of morphology. physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas. air breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover. fish are of considerable importance of the survival of the human species in the form ofnutritious and delicious food ofnumerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology. but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.
