This is a study of farm dynamics in eight African countries, drawing on a sample of more than 3000 farm households. It deals mainly with food crops and in detail with maize and makes a longitudinal analysis by systematically comparing current conditions with those obtaining when the farm was set up under its present management. From the study emerges an overall picture of inadequately exploited production potentials where farmers’ commercial energies are driven towards other food crops than grains, especially vegetables for urban markets. Commercial incentives in food grain production favour small groups of well-placed and usually male farmers, while, the lack of seed-fertiliser technology and commercial incentives means that smallholders devote their energies to other crops or to non-farm sources of income
