Agricultural water saving 10% urban water scarcity will be greatly alleviated
Qiu Baoxing, chairman of the China Urban Science Research Association, said on the 16th that my country's agricultural water consumption accounts for 61% of the country's total water resource utilization, while the effective utilization coefficient is only 0.51, which is 0.7 to 0.8 in developed countries. If my country's agriculture saves 10% of water, the shortage of urban water resources can be greatly alleviated.
Qiu Baoxing said: "Through urban water conservation, increasing the reuse rate of industrial water, and reducing the leakage of water supply pipe networks, the efficiency of urban water conservation can be increased by at least 15 percentage points; through urban sewage treatment, on-site reuse, rainwater collection, seawater desalination, etc. Measures can increase urban water supply by at least 15 percent.”
Fang Jin, deputy secretary-general of the China Development Research Foundation, said that my country's per capita freshwater resources are only a quarter of the world's average level, and it is a water-short country. Water environmental pollution, water supply performance, and low water efficiency have exacerbated the shortage. Experts believe that the advancement of my country's new urbanization is facing a severe water bottleneck.
Fang Jin believes that the process of urbanization in my country is unstoppable, and the key to breaking through the water bottleneck lies in system reform. To change the current highly fragmented situation of water resource management, learn from the successful experience of energy efficiency policy implementation, take comprehensive water efficiency as the policy starting point, establish a policy system based on water efficiency, coordinate water supply and water use, and coordinate the allocation of urban and rural water resources .
