摘要

The paper explores the relationship among population densities, agricultural production, land, labor, and rural incomes to expand the explanatory base of the Boserup hypothesis, which holds that with increasing population densities, a corresponding shift to greater agricultural production and more intensive use of the land takes place autonomously through the development of market forces. The movement away from traditional area-extensive farming methods is associated in the model with higher levels of technology, labor, and capital investment in land. The paper surveys existing literature and compiles data at the regional level for the six Managing Agricultural Development in Africa countries to isolate variables in the equation linking the intensity of land use, the increasing opportunity costs of idle or fallow periods, the effects of continuous cropping on the soil, and their policy implications.
