Agricultural, GIS and Remote Sensed data are integrated into an econometric model estimating Ethiopian wheat yields. The model explains 39% of total variation in wheat yield per hectare. Woredas produce between 9.8 and 86.5% of their locally attainable wheat yields. Four major regions produce between 48 and 61% of their estimated yield potential.
