    Within the world's livestock sector, broad production systems are defined and delineated. The criteria for the classification of world's livestock production systems are limited to integration with crops, relation to land and agro-ecological zones. A quantitative and qualitative description is given for each identified livestock production system in terms of feed and livestock resources, livestock commodities produced, production technology, product use and livestock functions, area covered, ge ographic locations, and human populations supported. Future trends and salient development issues are outlined for the systems and for the sector as a whole. The study also aims at providing insights into the importance of livestock systems across world regions and agro-ecological zones and related trends in order to provide orientation to decision-makers involved in livestock and agricultural development.

    One of the great challenges facing the world over the next decades is to preserve its natural resources while at the same time producing sufficient food to satisfy the demands of a growing human population. World population is expected to grow from 5.5 billion now to about 8 billion in the year 2020. Incomes also continue to grow, especially in the developing world and future projections estimate an annual per capita income growth ranging from about 3 percent in sub-Saharan Africa and Latin Amer ica to about 6 percent in Asia. Furthermore, there is a strong population move from the rural to the urban areas, again primarily in the developing world. By the year 2000, approximately 44 percent of the world's population is expected to reside in urban areas, up from 30 percent in 1980 (IFPRI, 1995). These trends will have immense consequences on the volume and composition of global food demand, especially in the developing world. Specialists of the International Food Policy Research Institute (IFPRI) estimate that the current demand of 1.7 billion tons of cereals and 206 million tons of meat, may rise by the year 2020 to 2.5 to 2.8 billion tons of cereals and at least 275 to 310 million tons of meat.
