Integrated modelling of climate change impacts in the soil–plant–atmosphere system can improve agroecosystem resilience and resource use efficiency. For the research on tomato (Solanum lycopersicum L.), bell sweet peppers (Capsicum annuum L.), and winter oilseed rape (Brassica napus L.), the CSM-CROPGRO-Tomato, CSM-CROPGRO-Papper and CSM-CROPGRO-Canola models were used as an example for Central European environment, including the Czech Republic. Their outputs were validated using an extensive experimental field dataset with contrasting climates and soils. The CSM-CROPGRO-Canola model has tested the three-winter oilseed rape (WOSR) varieties from three experimental sites. To identify the most promising agronomic adaptation strategies for thermophilic vegetables (VEG) in open-field growing conditions, the ability of the CSM-CROPGRO-Tomato and CROPGRO-Papper models have been tested. To assess the risk of compound climate/weather events (CEs) for WOSR production and the most promised areas with technical ripening of fruit tomatoes and sweet peppers, the ensemble of the Regional Climate Models for 2001–2020, 2021–2040 and 2041–2060 have been used. We found that linking the CSM-CROPGRO system with an ensemble of climate models is a reliable tool for testing new varieties of WOSR and VEG and assessing their suitability for future climate change.
