Abstract: Water shortage under climate change in the Haihe River basin and the effectiveness of adaptation measures were simulated and analyzed using China's Water Simulation Model. It shows that, with socio-economic development, water shortage in the Haihe River basin will increase by 25% in 2030, and climate change will further increase the shortage in water resources by 2%-4%. Both supply management measures and demand management measures can play important roles in mitigating water shortage. However, based on the multi-criteria assessment results, it is more feasible to implement demand management measures than supply management measures. For demand managements, the best policy is the mix water price policy through increasing both irrigation and industry water prices, and the next is adopting agricultural water-saving technology.

Key words: climate change, water shortage, adaptation measures, Haihe River basin
