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 stover biomass (in kg)/ Cumulative precipitation during crop growth period (in millimeter) The climate data at the national scale was made available from the National Aeronautics and Space Administration (NASA), Goddard Institute of Space Studies(https://data.giss.nasa.gov/impacts/agmipcf/agmerra/), AgMERRA.The dataset is stored at 0.25°×0.25° horizontal resolution (~25km). Soil parameter values were extracted from the soil property maps of Africa at 1 km x 1 km resolution (http://http://www.isric.org/projects/soil-property-maps-africa-1-km-resolution).
