This situation is expected to worsen under most future climate projections, which might increase the risks linked to food security and economies which depend on it. Providing insights about the potential responses of rainfed crops to climate change will helps on designing future adaptation strategies. In this study, large amount of data and the agro-hydrological model SWAT have been used to investigate future climate change impacts on rainfed wheat and sunflower crops in a semiarid watershed in Morocco (R'dom watershed). Downscaled CORDEX climate projections were used in generating future plants growth simulation for R'dom watershed in the 2031 to 2050 horizon under two Representative Concentration Pathways (RCPs): 4.5 and 8.5. The main results of climate change scenarios highlighted that R'dom watershed will undergo significant decrease in water resources availability with more impact under the scenario RCP 8.5. Water productivities of both studied crops could be lower by up to -21% in comparison with baseline situation. Different sustainable management strategies have been simulated using SWAT model under climate change context. The adopted approach succeeded in building up sustainable management strategies toward secured food security in the future. specialized MAROC ZONE ARIDE ZONE SEMIARIDE 072 126 098 183 03002 [8 ] 2020 2267-1242 I2CNP.International Conference on Climate Nexus Perspectives : Water, Food and Biodiversity, Khenifra (MAR), 2020/06/04 https://www.documentation.ird.fr/hor/fdi:010084436 10.1051/e3sconf/202018303002 2267-1242 [F B010084436] https://www.documentation.ird.fr/hor/fdi:010084436 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2022-12/010084436.pdf IRD - Base Horizon / Pleins textes 2022-02-21 2025-02-24 fdi:010084436 fre
