Abstract
The use of mixed systems for agricultural and forestry production have been practiced for centuries. In the tropics a simple system where the use of agricultural crops in assisting the establishment of forest plantations (taungya) is wide spreadandin Africa and elsewhere shifting agriculture in the past provided a sustainable land use system which is only breaking down under the pressure of increasing population. In general this paper considers all multiple cropping systems, including agroforestry, agrisilviculture and taungya (use of agricultural crops for assisting in the establishment of forest plantations) as mixed systems. Definitions of these systems are followed by discussions of background to multiple cropping, traditional African mixed cropping systems, and analysis of multiple cropping systems in Africa. It is indicated that there is no doubt that mixed cropping systems will continue in Africa, and that the complex and expensive external inputs needed to change traditional farming systems will only be available to the few
