Abstract: Abstract High water withdrawals for agricultural purposes during summer months led during the last decades repeatedly to intolerable ecological conditions in surface water bodies in the Broye region located in Western Switzerland. In this study, we assess different irrigation water withdrawal policies with respect to a farmer’s income and to the optimal irrigation and nitrogen fertilization strategies in potato production under current and future expected climate conditions in the Broye region. To this end, we optimize nitrogen and irrigation management decisions in potato production by the use of a bio-economic model and genetic algorithms. Our results show that limiting the water withdrawal amount leads to a substantial decrease in irrigation use, whereas the reduction in a farmer’s income in potato production is supportable.
