Perspectives in Soil Erosion in Africa: Whose problem?
There is considerable disagreement in the scientific community due to lack of quantitative data regarding both the extent and rate of soil erosion. There are also no formal models which can use what little quantitative data does exist to establish a relationship between erosion and productivity decline. Africa is beset by a variety of problems in addition to soil erosion, and they are more or less serious depending on the perspectives and values of the observer. It is the aim of this paper to examine soil erosion as it fits into the problem hierarchy of the farmer, the government and the donor and to try to understand why these different actors place different priorities on land husbandry activities, including sustainable agriculture programmes.
