Future Outlook

The trajectory of drought risk on the North China Plain will depend on the interaction of multiple factors: the pace of climate change, the effectiveness of water management policies, the rate of technological adoption, and the path of urban and economic development. Under a business-as-usual scenario, water scarcity is likely to worsen, with increasingly severe consequences for agriculture, food security, and economic stability. The depletion of groundwater reserves would continue,Leading to highier pumping costs, declining water quality, and irreversible damage to aquifer storage capacity.
