Abstract: Irrigation is seen as an appropriate adaptation measure to the effects of climate change. However, the costs of irrigation are not always covered by the additional revenue. Based on simulated yields using the crop growth model HERMES for different climate scenarios we estimate the profitability for three typical agricultural crops for different soil quality levels in the federal state of Brandenburg. The results show that not in all cases irrigation can be profitably applied. Medium quality soils are in general the sites that turn irrigation into a profitable revenue. Future crop price increases could turn irrigation more profitable, but the increasing irrigation water demands need to be met by water availability which is already a concern in some regions of Germany.
