There is an over dependence on rain fed agriculture in sub-Saharan Africa and not enough ways to deal with the effects of dry spells and droughts. As a result, grain yields are below one to n per hectare in most of the region. This has mistakenly been blamed on physical water scarcity. But it is not physical as much as it is economic. There is simply a lack of investments to both capture and boost water storage. 1 Most sub-Saharan African countries are currently using at most 5 percent of their rainwater potential. By recognizing and incorporating the green water—the water ignored in hydro logical planning—it may be possible to improve the food insecurity situation while also protecting the environment.
