Out of the total land area in Africa, only a fraction is used for arable land. Using soil, land cover and climatic characteristics a FAO study has estimated the potential land area for rainfed crops, excluding built up areas and forests – neither of which would be available for agriculture. According to the study, the potential – if realised – would mean an increase ranging from 150 – 700% percent per region, with a total potential for the whole of Africa in 300 million hectares. Note that the actual arable land in 2003 is higher than the potential in a few countries, like Egypt, due to irrigation.
