Potential for Agroforestry Adoption in Southern Africa: A comparative study of improved fallow and green manure adoption in Malawi, Zambia and Zimbabwe

Abstract

This paper summarizes the findings of three ex-ante studies, from Malawi, Zimbabwe and Zambia, that examined the potential for adoption of agroforestry technologies should they be extended to farmers. Ethnographic linear programme modelling of households in all three locations shows that the potential adoption of these technologies depends on household composition, farm size, and availability of draft power. Results show that both male and female headed households can adopt the technology. A seed selling incentive enhanced adoption through augmenting household income and benefited farmers by increasing funds available for discretionary use. In Zimbabwe there was a greater increase in discretionary cash for draft animal owners than non-owners. It is concluded that in Southern Africa, improved fallows are a viable alternative to chemical fertilizer use for small farmers.
