Rising population in Africa has resulted in a growing demand for consumer goods and basic necessities (food, shelter, clothing, and energy), causing a dramatic decline in the environment. Documented through case studies and photographs are five basic ecological issues facing Africa: the destruction of wildlife; the decline of natural habitats; pollution; land degradation; and human shelter. International agencies' roles in reversing the negative trends are examined.

East Africa is one of the most diverse and interesting tropical area on the planet. It is home not only to the last great megafaunal assemblage, but also to human populations with the highest growth rates. This book draws on the expertise of leading ecologists, each intimately familiar with a particular set of East African ecosystems, to provide the first in-depth and integrated account of the ecology, management, threats, and conservation of these diverse ecosystems. Summarizing the tremendous wealth of scientific research that has come out of East Africa in the last few decades, each chapter analyzes a given ecosystem type, taking the reader through the basics of its ecology, its historical use (and misuse) by humans, and its prospects for conservation. Throughout the book, linkages and similarities among ecosystems are emphasized, the historical and contemporary role of humans in shaping these ecosystems is considered, fundamental principles of ecology are considered, and interesting case studies are highlighted. Students and researchers in ecology, conservation biology, and environmental sciences will find this book useful in their work.

Driven by exponential population growth and the effects of globalization, haphazard development across Africa threatens the continent's natural resources, as housing and infrastructure encroach on ecological systems. In its updated second edition, this book documents through case studies the destruction of natural habitats and wildlife and presents collaborative approaches to sustainable, self-sufficient community development. The author describes in detail the conservation of ecological systems, especially in the context of land use and poaching, and highlights the important roles played by women and indigenous people.

Africa is not known as one of the more densely populated continents. Yet, the damaging marks of man's activities may be seen there dramatically. Many of Africa's ecological zones are fragile. Large scale soil erosion, resul tant cycles of drought and flash floods, downgrading of fauna and flora are well-known to many in general ways, as well as from detailed examination of a few areas. But large parts of Africa remain inaccessible. Very few students of Africa have the opportunity - or the tenacity - to travel over these vast areas or into the hidden corners that lie beyond the well-known routes of Africa. As FAO's Regional Wildlife and National Parks Officer for Africa, ANTooN DE Vos had the opportunity of travelling widely and studying and reporting on the acceleration of man-made changes in much of the continent. As an experienced practitioner of an important and difficult science, ecology, he has made a significant professional contribution with this book. It is our hope that those who read it will be encouraged to carryon the important work and the concern with this subject to which Dr. DE Vos has devoted so much of his knowledge, energy and personal commitments.

In view of the rapidly changing ecology of Africa ,this work provides benchmarks for some of the major, and more neglected, aspects, with an accent on historical data to enable habitats to be seen in relation to their previous state, forming a background reference work to understanding how the ecology of Africa has been shaped by its past. Reviewing historical data wherever possible it adopts an holistic view treating man as well as animals, with accent on diseases both human and animal which have been a potent force in shaping Africa’s ecology, a role neglected in ecological studies.

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'.
