Comparative output of calories starchy food crops in sub-Saharan Africa

The literature is replete with yield data, food consumption tables, and production data from various sources. These were used to derive the overall energy accruing from the production of the various starchy food crops in the African continent. In this study, the changes over time in the contribution of the principal starchy staples to food energy output in Africa were determined and their potential future roles are discussed. Country specific information was then considered for more specific action plans for the use of scarce research resources for the implementation of the themes identified by the researchers.
