Abstract：Water constitutes the central element within the Water-Energy-Food(WEF)Nexus.To safeguard national food and energy security,it is essential to strengthen water resource management and ensure the coordinated safety development of water,energy,and food.Based on a comprehensive review of research progress on the WEF Nexus both domestically and internationally,as well as a scientific understanding of the fundamental principles of the WEF Nexus,this paper analyzes the prevailing issues in the development and utilization of water resources,energy,and food in various provinces of China.It reveals four major challenges facing the current development of the WEF Nexus:the growing energy demand intensifies the structural contradictions in energy security,increasing instability exacerbates food security risks,resource mismatches tighten water resource constraints,and high-quality development imposes higher requirements on water-energy-food-ecology systems.Targeted regional sustainable development models and strategies are proposed,tailored to regional characteristics and high-quality development goals.Research indicates that in resource-rich Northwest China,water scarcity can be alleviated through the"Four Waters and Four Determinations"policy,water rights trading,and water transfer projects.In the groundwater overexploitation areas of the Jing-Jin-Ji region,it is necessary to optimize the food security layout and strengthen the coordinated regulation of water and energy.In Northeast China's grain production areas,food production space should be expanded while ensuring the rational development and utilization of water resources.In southern regions abundant in water resources,deepening agricultural supply-side structural reform and promoting integrated development of"Water-Wind-Solar-Storage"is essential.This research aims to provide scientific support and decision-making references for navigating towards a green,low-carbon,and sustainable development path.
