The map shows projections of changes in the crop water deficit for grain maize in the growing season in the 2030s compared with the
reference period centred on 2000 for two different global climate models. The simulations were performed using the WOFOST model
for the RCM8.5 emissions scenario. Red indicates an increase in the crop water deficit and blue indicates a reduction of the deficit. Areas
where the seasonal crop water requirement regularly exceeds the water availability are marked by hatching.
