East African Ecosystems and Their Conservation


Book Description

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.




Management of Semi-Arid Ecosystems


Book Description

Extensive regions of the world have a climate which, whilst permitting development of a continuous vegetative cover, is too dry for successful annual cropping. These are the semi-arid areas where land use is based on the natural vegetation. Easily degraded and difficult to maintain, they are under increasing pressure as expanding human populations move in and endeavour to force a living from them. As a result they contain some of the worst examples of resource degradation. This book examines the problems and opportunities involved in man's use of semi-arid areas. The authors are all actively involved in research and land management in the areas discussed. Each chapter begins with a detailed, up-to-date account of the ecology of the region (its climate, soils, vegetation, fauna and main ecological characteristics). This is followed by a history of land use, problems involved in its management, a review of current research and recommended land use practices. The common features of semi-arid ecosystems are brought together in a final section.













Fragmentation in Semi-Arid and Arid Landscapes


Book Description

With detailed data from nine sites around the world, the authors examine how the so-called ‘fragmentation’ of these fragile landscapes occurs and the consequences of this break-up for ecosystems and the people who depend on them. ‘Rangelands’ make up a quarter of the world’s landscape, and here, the case is developed that while fragmentation arises from different natural, social and economic conditions worldwide, it creates similar outcomes for human and natural systems.




Resilience and Collapse in African Savannahs


Book Description

This book assesses the causes and consequences of environmental change in East Africa, asking whether local African communities are sufficiently resilient to cope with the ecological and social challenges that confront them. It focuses on the savannahs of the Baringo-Bogoria basin, and the surrounding highlands of Kenya’s northern Rift Valley that form the social-ecological system of the specialised cattle pastoralists and niche agricultural farmers who occupy these semi-arid lands. Historical studies of resilience spanning the past two centuries are linked with analysis of current environmental challenges, and the ecological, social, economic and political responses mounted by local communities. The authors question whether the most recent challenges confronting the peoples of eastern Africa’s savannahs – intensified conflicts, mounting poverty driven by demographic pressures, and dramatic ecological changes brought by invasive species – might soon led to a collapse in essential elements of the specialised cattle pastoralism that dominates the region, requiring a re-orientation of the social-ecological system. This book was originally published as a special issue of the Journal of Eastern African Studies.
