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.

Yield Target and Poverty Reduction Model for South Asia

Yield Target and Poverty Reduction Model for South Asia

Years Covered: 
2010 - 2030
Publisher:

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).
