In the Sahel, sandy soils are widespread and support not only most of pearl millet production, the major staple crop in the region, but also forage production for livestock. Parent sediments of these soils have an aeolian origin and hence are prone to wind erosion. However, the clay content, albe...

Increasing frequency of drought events coupled uncertainty imparted by climate change pose grave threat to agriculture and thereby overall food security. This is especially true in South Asian region where world’s largest concentration of people depends on agriculture for their livelihood. Indic...

The pastoral areas of Ethiopia are one of the most drought-vulnerable with chronic food deficiencies between 1980-1 and 1999-2000 these areas suffered 3 major droughts. In all droughts the Borana pastoralists lost 35-67 percent of their livestock. The position of the southern Ethiopian rangelands...

In studies of 25 rangeland sites selected along the S.-N. bioclimatic gradient and on the main soil types in the Gourma (Sahel, Mali), herbage cover, standing mass and botanical composition were measured in relation to seasonality of grazing and grazing intensity. When different sites were compar...
