A food demand system is proposed, based on demand for energy, variety, and tastes of foods. By specifying utility as an explicit function of these characteristics, the entire matrix of demand elasticities can be derived for n foods and one nonfood from prior specification of just four elasticities, while avoiding any assumption of separability between foods. This framework can explain why poorest groups often are most price-responsive, but also can account for highest price-responsiveness by middle income groups.

The author argues that African rural areas behave differently from rural areas in fully commercialized market economies. In commercialized economies, price signals quickly induce factor flows, including items such as investment and technological change. A need for more food is quickly translated into production of either more food or more non-food items to finance food imports. If agricultural potential exists in such countries, market incentives will encourage both appropriate output mixes and investment inflows; growth will then occur.

Estern Colombia, the Llanos, is constituted of broad grass formations. These big expanses of savannahs present a huge potential for extensive bovine breeding. Unfortunately, these natural pastures have a low productivity and a feeble quality, due to low fertility soils with a deficiency in phosphorus and a hgih acidity. In regard to the importance of the breeding for the region, it`s essential to know the savannahs `characteristics in order to ameliorate the exploitation which is done of them.

Reports on completed and planned research to examine farmers' perceptions of different breeds, the discretion they exercise over breed composition, and the impacts of breed perceptions on breeding practices. ILCA has recently undertaken three household surveys that shed light on farmers' breed preferences and breeding practices. The survey results indicate that farmers' breed prortfolios are the outcome of dynamic processes that vary across farmers and environmental conditions.
