Medium need for potential irrigation for the 30-year period 2021-2050, climate change scenario (RCP2.6)

The map shows the mean potential need for irrigation (in mm) for the 30-year period 2021-2050 under the “Climate Protection” scenario (RCP2.6). Irrigation requirement is the mean amount of irrigation within the growing season (April-September) required to maintain 40 % usable field capacity (nFK) in the effective root space (nFCs). The average amount of irrigation is calculated for an average of the fruit species winter wheat, winter barley, winter barley with intermediate fruit, summer barley, corn, sugar beet and potatoes. The climate models are driven by the “climate protection” scenario (RCP2.6). This is a scenario of the IPCC, which means significant efforts in climate protection and low emissions. The results of all climate models are equally likely. Therefore, in addition to the mean, which shows a tendency, the upper (maximum) and lower (minimum) edge of the result bandwidth can be retrieved via the maptip.
