Trends in water availability for African maize, 1979-2010

We recently published a paper in Environmental Research Letters that examines changes in the water available for growing maize in sub-Saharan Africa between 1979 and 2010. We identified trends in rainfall, potential evapotranspiration (PET, which is the atmospheric demand for water), and the ratio of the two (also known as the aridity index), and also quantified the factors responsible for changing PET.
