Technology Options for Sustainable Agriculture in Sub-Saharan Africa Scientific papers presented at the OAU/STRC - SAFGRAD Regional Workshop on Technology Options and Transfer Systems for Sustainable Agricultural Production in Sub-Saharan Africa, Abidjan, Cote d'Ivoire, 26-29 April 1995

The paper proposes a theory of technology development for semi-arid regions. It then evaluates the theory by reviewing the characteristics of technologies successfully introduced into the regions. Modeling is then used to identify some constraints to further technology introduction of the type proposed. Some specific policy recommendations to accelerate technology introduction are made.
