Sub-Saharan Africa (SSA) remains a hotspot of water and food insecurity. The absolute number of undernourished people has increased from 169 million to 239 million in SSA over the past two decades (WFP 2010). These current deficits in food supply might rapidly increase in the future in view of the projection of a doubling of Africa’s population between 2010 and 2050 (about 75% of the global population growth is projected to happen in Africa; Africa Progress Report 2012: 34). Analogously, FAO projections for SSA show a growth in total food demand by up to 221% and even higher growth in demand for resource-intensive meat products (371%) by 2050 (Bruinsma 2009). These additional demands will have to be met by an increase in the use of natural resources.
