Maize Yield Gap Ratio Quadrant by Country

Maize Yield Gap Quadrant Analysis

Tool Type: Interactive data query
Publication Date: May, 2013

Tableau Viz to interactively show the data used in the "Minding the Yield Gap in Africa: A Country-Level Analysis" blog post published on May 23, 2013. In this analysis, maize actual and rainfed potential yields at the pixel level (~100 km2) were normalized across sub-Saharan Africa and aggregated by country.

Yield Target and Poverty Reduction Model for South Asia

Yield Target and Poverty Reduction Model for South Asia

Tool Type: Model
Publication Date: January, 2011

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).

Yield Target and Poverty Reduction Model for Sub-Saharan Africa

Tool Type: Model
Publication Date: January, 2011

This comparative static model estimates potential yield increases and poverty reduction effects based on user-selected yield closure gap assumptions. A poverty-productivity elasticity (extracted from the relevant literature) and crop-specific adjustments are used to link productivity gains to a lowering of poverty prevalence rates and poverty headcounts compounded over a 20 year period.
