Today, vegetable production is already limited by local climate and water availability. Knowledge has to be generated for crop management adapted to climate change. Evaluating potential consequences for vegetable production in a model growing region is the scope of this investigation. Simulations of climate conditions and in that respect the use of different climate models allow estimating a broad range of scenarios affecting cultivation. Analysis focuses on climatic parameters relevant for future irrigation demand. By estimating the climatic water balance (CWB), seasonal water demand and crop specific vulnerabilities to water deficit can be revealed. These objectives require knowledge of potential changes in time and duration of vegetable cultivation, gained from analysing thermal growing season (TGS).A broad range of scenarios was achieved for the German region “Hessian Reed” by applying A1B scenario and using the regional models WETTREG 2010, C-CLM and REMO, driven by the global models ECHAM5 and HadCM3, respectively. Simulations cover the period from 1971 to 2100; the validation is based on the period 1971 to 2000. For onion, crop specific CWB was calculated by employing crop coefficients of the Geisenheim Irrigation Scheduling, following FAO-56. TGS was derived from simulated onset and duration of plant growth stages based on temperature sum.Precipitation pattern vary between the models, but still follow a similar trend to higher evaporative demand. CWB decreases by 3mm/d (WETTREG) and 2mm/d (C-CLM), respectively. Maximum duration of dry periods increases from 33 to 53 d and occur more frequently from 343 to 457 times for REMO, representing maxima compared to C-CLM and WETTREG. TGS shifts from DOY 60 to 21 for sowing date, but extends from DOY 183 to 208 due to lower temperature (C-CLM). In contrast to the expected increasing irrigation demand in case of unchanged TGS, CWB becomes less negative with TGS-shift
