What are the disadvantages of wasting water resources?

1. If you don't drink water, you will die of thirst. 2. China is a country short of water resources. According to statistics, China's per capita water resources is only equivalent to 1/4 of the world's per capita water resources; Among the more than 6 cities in China, more than 4 cities have water shortage problems, including 11 cities with serious water shortage, and the annual total water shortage in cities nationwide reaches 6 billion cubic meters. Experts predict that the population of China will reach the peak of 1.6 billion in 23, when the per capita water resources will be only 1,75 cubic meters, and China will become a country with serious water shortage.

Wu Jisong, executive deputy director of the National Water Conservation Office and director of the Water Resources Department of the Ministry of Water Resources, believes that the current situation of water resources in China is a "moderate shortage", which is mainly caused by management problems and lack of comprehensive water conservation management. The core of sustainable utilization of water resources is to improve water use efficiency. The Water Law puts water conservation in a prominent position and determines the overall goal of establishing a "water-saving society". Therefore, the key to achieve the balance between supply and demand of water resources is to build a water-saving society-rationally develop and utilize water resources, and vigorously improve the utilization rate of water in all aspects of industrial and agricultural water use and urban domestic water use, so that the awareness of "water crisis" is deeply rooted in people's hearts, forming a situation in which everyone loves water and saves water all the time. The goal of water resources management in China is to achieve the balance between supply and demand of water resources through the construction of a water-saving society, or to achieve "no shortage of water" in the sense of supply and demand balance. It is imperative to build a water-saving society. Because of its great significance, some experts even call it a "social revolution" related to the harmonious coexistence between man and nature.

In September this year, Wu Jisong specially visited South Africa and Iran, which are similar to China in terms of water resources and economic development. Both countries have basically achieved a balance between supply and demand of water resources through effective management and water conservation. He stressed that for a region, from the minimum standard of maintaining sustainable development-3 cubic meters of water per capita to the abundant water standard of 3 cubic meters, it can be regarded as a "water shortage" situation. International experience shows that as long as there is a correct concept of water use, a scientific water use system and a reasonable water use method, the balance between supply and demand can be achieved under the condition of "water shortage". On the contrary, even if the per capita water resources exceed 3, cubic meters, if it is wasted in large quantities and pollution is not effectively controlled, the balance between supply and demand of water resources may still not be achieved.

system engineering in the ascendant

"The construction of water-saving society is a social revolution and a complex system engineering. It is necessary to innovate and build water-saving system, water-saving economy, water-saving science and technology and water-saving culture." In order to steadily promote the construction of a water-saving society, the Ministry of Water Resources has selected three different types of areas for pilot projects: Zhangye City, Gansu Province, which is dry and rainy in the west, Mianyang City, Sichuan Province, which is relatively rich in water resources, and Dalian City, Liaoning Province, which is seriously short of water.

Zhangye city, which carried out pilot work in advance, has achieved initial results. The successful water diversion of Heihe River is one of the landmark achievements in the construction of water-saving society in Zhangye. Heihe River is the second largest inland river in China, and Zhangye lives in it. The ecological environment of Ejina Oasis in Inner Mongolia in the lower reaches of Heihe River is seriously deteriorated due to the drastic reduction of upstream water inflow. According to the emergency plan of Heihe River regulation initiated by the state, Zhangye will reduce the water diversion of Heihe River by 58 million cubic meters, which is a great challenge for Zhangye, who is "oasis with water and desert without water". However, in the construction of water-saving society in Zhangye, people's awareness of water-saving has generally improved, and by adjusting industrial structure and planting structure, water-saving transformation and water use system reform in irrigation areas have been carried out.

establishing water-saving system is the focus of water-saving management. According to reports, the Ministry of Water Resources is actively organizing the revision and drafting of water resources management regulations. The Measures for the Administration of Water Supply Price of Water Conservancy Projects have been promulgated, and the Measures for the Implementation of Water Permit System have been submitted to the State Council for review. The drafting of the Regulations on the Management of Water Conservation has been completed, and the Measures for the Administration of Water Resource Fee Collection is under preliminary investigation.

at the same time, local water resources legislation is also in full swing. Guangdong and Jiangsu have issued water resources management regulations, and Tianjin and Shandong have issued water conservation management measures; Dalian, Hohhot, Changchun, Qingdao, Harbin, Nanjing, Zhengzhou, Ningbo and other cities have also introduced local laws and regulations on water conservation and water resources management. These laws and regulations have laid a legal foundation for building a water-saving society.

"People's War" with a long way to go

Through efforts in recent years, China's water-saving cause has made great progress, but compared with some developed countries, we still have a long way to go-

Agriculture is a big user of water resources and a big waste of water resources. In our country, "soil canal water delivery, flood irrigation"
