ABSTRACT
Low-resource agriculture in Sub-Saharan Africa supports a wide range of population densities. A study of Cameroon shows average rural population densities by province varying from 3.7 to 82.0 persons per square kilometer, with densities in some regions going as high as 200 per square kilometer. In seeking the relationship between population density and natural resource distribution, African crops are a misleading indicator. In the English agricultural revolution, the Norfolk system of management with its new crops of turnips and clover and its elimination of fallow represented a diversification of production, even though the main sources of farm revenue remained the same as under the old system. The desirability of diversifying outputs of lowresource agriculture in Sub-Saharan Africa has long been recognized by nutritionists, whose special knowledge makes them concerned with what products of the farm stay on the farm as well as with what products are sold in markets.
