Mitigating Drought Impacts in Drylands : Quantifying the Potential for Strengthening Crop- and Livestock-Based Livelihoods

Drylands account for three-quarters of Sub-Saharan Africa's cropland, two-thirds of cereal production, and four-fifths of livestock holdings. Today frequent and severe shocks, especially droughts, limit the livelihood opportunities available to millions of households and undermine efforts to er...
