Migrations and nutritional status in the sahel.

In the Sahel, migration is of considerable importance. It permits the peasants to adjust to variable food conditions. In areas affected by food shortages, cluster sample studies of villages showed that, as the number of recently abandoned houses in a cluster increased, the prevalence of malnutrition decreased, and this linear trend was significant (p < 0.05). This phenomenon tends to reduce the prevalence of malnutrition in these areas, and it emphasizes the fact that the malnutrition rate is a late indicator when used for nutritional surveillance. The article provides also a brief description of the current migration patterns in the Sahel and underlines the effects droughts have had on them.
