Abstract：Climate change has profoundly impacted the global water cycle and food production patterns,increasing uncertainty and challenges in water resource management and food security.This paper analyzes the effects of climate change on various elements of the water cycle,including precipitation,runoff,evapotranspiration,soil moisture,and groundwater,and assesses the potential impacts of rising temperatures,greenhouse gas emissions,and extreme weather events on crop growth,yield,and food security.In response to these challenges,several strategies are proposed:advancing the construction of the national water network,implementing agricultural water-saving measures,reducing agricultural emissions and promoting carbon sequestration,cultivating crop varieties with high resilience,and managing the water-food-energy nexus in a coordinated manner.It is also recommended to conduct differentiated research based on various climate models and water resource management conditions to formulate climate-adaptive strategies tailored to local circumstances.
