Abstract. With climate change, the increasingly limited availability of irrigation water resources poses a major threat to agricultural production systems worldwide. This study explores adaptation options in soil and crop management reduce yield losses due scarcity restrictions during 2022 summer drought. The focus is on potato Broye catchment Switzerland, which representative many mid-sized lowland catchments central Europe facing reduced availability. We employed field-scale agro-hydrological Soil–Water–Atmosphere–Plant (SWAP) model distributed manner simulate regional demand, yields, deficits under drought stress. results suggest that bans led 16.4 % reduction 59 deficit water. Our findings adding 1 organic carbon (SOC) down depth 60 cm could have loss only 7 %. Planting earlier-maturing varieties less favorable pedoclimatic conditions further improves productivity (IWP) reduces demand by 26 In this case, however, there tradeoff yield, can be −14.8 Overall, our highlight great value for preventing droughts using example recently experienced year. Furthermore, we show use efficiency optimized location-specific combinations choices. face future exacerbated measures studied here represent valuable mitigate dependence irrigation.
