Resumen
Descripción
More than 90 percent of the population
in the Sahel lives on agriculture. The fact that crop
production has not kept up with population growth during the
last two decades is attributed to land degradation and
productivity decline resulting in increased levels of rural
poverty, food shortages and chronic food insecurity. In
response, since the 1980s, Sahelian farmers have
experimented with various soil and water conservation
techniques to restore, maintain or improve soil fertility.
