Williams, Timothy O.Taal, B.M.Villholth, Karen G.Johnston, Robyn M.Giordano, Meredith A.[Accessing and putting water to productive use in Sub-Saharan Africa]Accessing and putting water to productive use in Sub-Saharan Africa

Land degradation is a major challenge limiting crop production in Ethiopia. Integrated soil and water conservation is widely applied as a means to reverse the trend and increase productivity. This study investigated the effects of such integrated approaches at two sites, Jeldu and Diga, in Wester...
