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.

Climex/Dymex Pest/Disease Modeling (HarvestChoice Modifications)

Tool Type: Model
Publication Date: January, 2010

CLIMEX is a software program (written in DYMEX) that estimates the potential geographical distribution and seasonal abundance of a plant pest/disease in relation to climate. HarvestChoice has invested in the extension of the CLIMEX package to deal with climate time series rather than average climate conditions.
