To increase food production, identifying the regions with untapped production capacity is of prime importance and can be achieved by quantitative and spatially explicit estimates of Water use efficiency, thus considering the spatial variation in environment and the production system.

The unit is kilogram per millimeter (kg/mm). Water Use Efficiency (WUE)= Maize biomass (in kg)/ Cumulative precipitation during crop growth period (in millimeter) The climate data at the national scale was made available from the Terrestrial Hydrology Research Group, Princeton University (http://hydrology.princeton.edu/data.php) at a resolution of 10 km x 10 km. The dataset was constructed by combining a suite of global observation-based datasets with the NCEP/NCAR reanalysis. Soil parameter values were extracted from the soil property maps of Africa at 1 km x 1 km resolution (http://www.isric.org/data/soil-property-maps-africa-1-km).
