Informed livestock sector policy development and priority setting is heavily dependent on a good understanding of livestock production systems. In a collaborative effort between the Food and Agriculture Organization and the International Livestock Research Institute, stock has been taken of where we have come from in agricultural systems classification and mapping; the current state of the art; and the directions in which research and data collection efforts need to take in the future. The book also addresses issues relating to the intensity and scale of production, moving from what is done to how it is done. The intensification of production is an area of particular importance, for it is in the intensive systems that changes are occurring most rapidly and where most information is needed on the implications that intensification of production may have for livelihoods, poverty alleviation, animal diseases, public health and environmental outcomes. A series of case studies is provided, linking livestock production systems to rural livelihoods and poverty and examples of the application of livestock production system maps are drawn from livestock production, now and in the future; livestock's impact on the global environment; animal and public health; and livestock and livelihoods. This book provides a formal reference to Version 5 of the global livestock production systems map, and to revised estimates of the numbers of rural poor livestock keepers, by country and livestock production system.

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.
