AN EVALUATION OF SMALLHOLDER LAND-USE FOR CASSAVA PRODUCTION IN SOUTHERN NIGERIA

Cross-sectional data from Edo and Ogun States in 1989-1990 were used to examine smallholder cassava production in two different ecological zones in southern Nigeria. Using a combination of gross margin, benefit-cost analysis, land-use intensity and plant diversity index, the economic and ecological implications of cassava production were evaluated. The results provide evidence for desirable financial returns from cassava production but at great risk to the stability of woody plants and the environment. However, data on the incidence of land tenure support the view that property rights under the traditional land-tenure system are a constraint to the farming system.
