This paper reports on soil organic matter losses by erosion and leaching, and on organic matter management in five African countries. The effects of biomass management and tillage on runoff, erosion and restoration of soil productivity were studied in sets of runoff plots. In relation to increasing population, we also questioned whether it was possible to reach sufficient yields with biomass only, or whether additional mineral fertilisers were necessary.
