Plate 68 - Max-Planck Institute of Meteorology (ECHAM4 2080): Impacts of climate change on multiple cropping production potential of rain-fed cereals

> Climate change impacts by grid-cell are visualized using a normalized difference index. They are calculated by dividing the difference in cereal production capacity between future and current production potential by their sum. The index ranges from a value of -100 to + 100; the former indicates complete loss of production, the latter occurs in areas where cereal production is not possible under current climate conditions but would be feasible with climate change.
