HarvestChoice keeps catalogs of both raster and vector maps of sub-Saharan Africa (downloadable in either ASCII or ESRI Shapefile formats) along with their associated datasets. We also provide access to over 400 articles, survey and census reports on agriculture-related topics in support of investment targeting and prioritization decisions.

Comparative static model used to estimate long-term aggregate potential yield gains and aggregate potential poverty reduction effects from narrowing yield gaps for selected commodities in selected regions. The model allows for differentiated yield gap closure and technology adoption scenarios in focus and non-focus countries and for focus and non-focus crops. The model also accounts for varying "poverty-productivity" elasticities across commodities (a synthetic measure linking productivity gains and poverty reduction).

Here we document and discuss developments regarding aggregate input, output, and productivity developments within South Africa. To do so we draw on an entirely new set of production data stretching back to 1910/11 reported in Liebenberg 2010, as well as related evidence reported by other studies for South Africa and other countries within subSaharan Africa.
