The nations of Subsaharan Africa experienced declining levels of food production per capita throughout the 1970s and early 1980s, particularly in the area of livestock production. Addressing that problem, the authors of this book assess in a systems context the environmental, biological, and social constraints on future African livestock development and consider prospects for improving productivity, They focus especially on changes needed in production and marketing systems, pointing to important policy considerations . The book is divided into four parts containing twenty-one chapters, each authored by one or more respective authorities in his or her field. Each section in its own way addresses the entire set of questions; topics include aspects of animal breeding and nutrition, anthropology, economics, ecology, farming systems, governmental policy, land tenure, marketing, modelling, and veterinary medicine.

Many policy makers in East Africa have preconceptions about the value of pastoralism as a land-use system believing it to be economically inefficient and environmentally destructive. Yet, this is not evidence-based. Not only is there no consensus on what is a dynamic economic model of pastoralism, no mechanisms exist to inform government decision-making of its comparative advantages over alternative land uses. This paper argues that pastoralism does make a significant contribution to society and that, with better understanding, planning and data collection, its value can be demonstrated. The paper presents a preliminary framework for assessing the benefits of pastoralism that goes beyond conventional criteria relating to livestock and their by-products. While the paper focuses on East Africa, much of the analysis is applicable to pastoral systems in other regions of Africa.
