Developing countries have very diverse food consumption patterns and agricultural production systems. The proportion of meat in national diets varies from negligible in some countries in central Africa to 30-40% in some countries in Latin America and Mongolia. However, the demand for meat in developing countries is increasing rapidly (53%/year from 1982 to 1993), as the result of population growth and the trend for people to move to the cities. Growth rates in consumption are greatest in Asia, with China dominating the statistics, in view of the size of its population. Theoretically, livestock production can be increased to meet this demand, but the multiple roles of livestock in developing countries must be recognized if this is to be achieved in a sustainable manner. Resource-poor farmers who keep livestock may value more highly their contribution to livelihoods and to crop production, through provision of draught power and improvements in soil fertility through the recycling of manure, than the production of more meat. Recognition of the goals of the farmer and the wishes of the consumer regarding meat quality need to be reflected in the way in which opportunities for increasing meat production are identified and communicated to farmers. The impact of the global economy on cereal prices, for example, will also influence which interventions will be economically viable. Interpretation of information in an integral manner, using geographical information systems, mathematical models and/or simple spreadsheet models will be an important ingredient in turning scientific knowledge into increased meat production in developing countries.
