Climate change has become a key factor affecting global agricultural production and the sustainable utilization of water resources. This paper systematically reviews the mechanisms by which climate change influences agricultural water resources and the corresponding regulation strategies, aiming to comprehensively assess the challenges to the balance of agricultural water supply and demand and to explore effective approaches for adaptation and mitigation. First, it analyzes the impacts of rising temperatures, evolving precipitation patterns, and the increasing frequency of extreme climate events on the global water cycle. Second, it highlights the dual effects of climate change on the supply and demand of agricultural water resources, including changes in the availability of surface water and groundwater, as well as the dynamic adjustment of crop water requirements. By comparing regional case studies, the paper reveals differentiated responses in arid and semi-arid areas, temperate and tropical regions, and areas dependent on glacier and snowmelt water under climate change. Furthermore, it reviews the critical role of adaptive measures such as water-saving irrigation, the breeding of drought- and stress-resistant crops, and integrated water resources management policies in addressing climate change. Finally, it summarizes future projections of climate change impacts on agricultural water resources, identifies current research gaps, and proposes future directions in multi-source data integration, model refinement, and interdisciplinary research. This paper provides valuable scientific reference for the sustainable development of agricultural water resources.
