The concrete meaning of four waters and four determinations

The specific meanings of four waters and four determinations are as follows:

1. Develop by water: determine the scale and speed of economic and social development according to the renewable capacity and sustainable utilization degree of water resources. Water-deficient areas should restrict or adjust the industrial structure to avoid over-exploitation of water resources.

2. Living by water: according to the supply capacity and quality of water resources, determine the standard and mode of water supply for residents. It is necessary to encourage water conservation, improve the efficiency of water resources utilization, and ensure people's basic living needs.

3. Determining agriculture by water: according to the balance between supply and demand of water resources and the irrigation demand of farmland, determine the scale and mode of agricultural production. It is necessary to popularize water-saving irrigation technology, improve the efficiency of farmland water conservancy facilities and reduce agricultural water consumption.

4. Determining ecology by water: According to the ecological environment function of water resources and the protection demand of ecosystem, determine the development and utilization mode and ecological protection measures of water areas. It is necessary to strengthen water environmental protection, restore the natural ecological functions of wetlands and rivers, and maintain biodiversity.

The role of four waters and four determinations:

1. Promote sustainable development: Water resources are the foundation for human survival and development, and also an important support for economic and social development. Based on the development of water resources, water resources can be rationally planned and utilized to avoid over-exploitation and waste and realize sustainable economic and social development.

2. Ensuring people's living needs: Water is the basic need of people's life. Living on water can ensure that people have enough drinking water and good living water conditions. At the same time, by saving water, we can improve the utilization efficiency of water resources, reduce the living cost of residents and improve the quality of life.

3. Support agricultural production: Agriculture is an important part of the national economy and a major consumer of water resources. Determining agriculture by water can reasonably arrange the scale of farmland irrigation and agricultural production, popularize water-saving irrigation technology, improve the efficiency of farmland water conservancy facilities, reduce agricultural water consumption, and ensure food security and sustainable agricultural development.

4. Protecting the ecological environment: Water resources are an important part of the ecosystem and play an important role in maintaining biodiversity and ecological balance. Using water to determine ecology can protect the ecological environment of water areas, restore the natural ecological functions of wetlands and rivers, maintain biodiversity, and prevent water pollution and ecological damage.
