First published in 1988, this work provides a comprehensive picture of the range of physical environments in Africa, focusing upon those characteristics and issues central to the management of environmental resources. Beginning with an overview of the geographical and environmental history of Africa, the authors also provide to the evolution of the management of resources and then details a broadly defined ecosystem approach, in which major environmental resource issues are identified and addressed in the tropical rainforest, the Savannah dry-forest, the arid and semi-arid areas, the highlands, and the extra-tropical zones of Northern and Southern Africa. The book is designed to contribute to a better understanding of African environmental and resource-management problems and this reissue should be welcomed by students of Africa and of environmental resource management problems in general.

Originally published between 1986 and 1989 the 8 volumes in this set reflect the research and debate surrounding many issues for the African economy, society and culture and as such make a vital contribution to effective development, both rural and urban. They re-issue key titles from the International African Library and the International African Seminars and address themes of direct relevance to contemporary Africa on topics as diverse as medicine, migration, housing, pastorialism and marriage.

Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas.This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.

Pastoralism and Climate Change in East Africa provides systematic and robust empirical investigations on the impact of climate change on pastoral production systems, as well as participating in the ongoing debate over the efficacy of traditional pastoralism. This book is an initial product of the Project Building Knowledge to Support Climate Change Adaptation for Pastoralist Communities in East Africa implemented by the Centre for Climate Change Studies of the University of Dar es Salaam with support from the Open Society Initiative for Eastern Africa. Traditional pastoralism has proved to be a resilient and unique system of adaptations in a dynamic process of unpredictable climatic variability and continuous human interactions with the natural environment in dryland ecosystems. Pastoral adaptations and climate-induced innovative coping mechanisms have strategically been embedded in the indigenous social structures and resource management value systems. Pastoral livelihoods have, nevertheless, become increasingly vulnerable to climate change impacts as a result of prolonged marginalization and harmful external interventions. The negative effect of global climate change has been an added dimension to the already prevailing crisis in the pastoral livelihood system, which is substantially driven by non-climatic factors of internal and external pressures of change such as population growth, bad governance and shrinking rangelands lost to competing activities.

The first of three books in IFPRI's climate change in Africa series, West African Agriculture and Climate Change: A Comprehensive Analysis examines the food security threats facing 11 of the countries that make up West Africa -- Benin, Burkina Faso, Côte d'Ivoire, Ghana, Guinea, Liberia, Niger, Nigeria, Senegal, Sierra Leone, and Togo -- and explores how climate change will increase the efforts needed to achieve sustainable food security throughout the region. West Africa's population is expected to grow at least through mid-century. The region will also see income growth. Both will put increased pressure on the natural resources needed to produce food, and climate change makes the challenges greater. West Africa is already experiencing rising temperatures, shifting precipitation patterns, and increasing extreme events. Without attention to adaptation, the poor will suffer. Through the use of hundreds of scenario maps, models, figures, and detailed analysis, the editors and contributors of West African Agriculture and Climate Change present plausible future scenarios that combine economic and biophysical characteristics to explore the possible consequences for agriculture, food security, and resources management to 2050. They also offer recommendations to national governments and regional economic agencies already dealing with the vulnerabilities of climate change and deviations in environment. Decisionmakers and researchers will find West African Agriculture and Climate Change a vital tool for shaping policy and studying the various and likely consequences of climate change.

In this volume, the erosion and conservation measures discussed are, for the most part, those under unirrigated agriculture. The use of irrigation could cause significant changes in the growing seasons, and in the agricultural calendar, especially in the warmer climates where temperature is not a limiting factor. It is further noted that much of the material in this volume has been prepared with the developing countries of the so-called Third World in mind. In many of these countries there is a dearth of basic data, such as long-term hydrological records, detailed soil and topographic surveys, and experimental results for various types of erosion control measures. Some design procedures cannot be imitated or copied directly from those of the technologically more advanced countries. Consequently, emphasis will be placed, wherever possible, upon simple empirical methods of design, and approximate solutions within the limitations of the available data, technical possibilities, and financial resources of the Third World countries. Much of the numerical data and calculations will be presented in the metric system.
