      abstract = {Two possible adaptation options to climate change for  Sub-Saharan Africa are analyzed under the SRES B2 scenario.  The first scenario doubles irrigated areas in Sub-Saharan  Africa by 2050, compared to the baseline, but keeps total  crop area constant. The second scenario increases both  rainfed and irrigated crop yields by 25 percent for all  Sub-Saharan African countries. The two adaptation scenarios  are analyzed with IMPACT, a partial equilibrium  agricultural sector model combined with a water simulation  model, and with GTAP-W, a general equilibrium model  including water resources. The methodology combines  advantages of a partial equilibrium approach, considering  detailed wateragriculture linkages with a general  equilibrium approach, which takes into account linkages  between agriculture and non-agricultural sectors and  includes a full treatment of factor markets. The efficacy  of the two scenarios as adaptation measures to cope with  climate change is discussed. Due to the low initial  irrigated areas in the region, an increase in agricultural  productivity achieves better outcomes than an expansion of  irrigated areas. Even though Sub-Saharan Africa is not a  key contributor to global food production or irrigated food  production, both scenarios help lower world food prices,  stimulating national and international food markets.},
