Facing the shortage of water resources, water saving is the priority

Release date: November 5, 2019 14:45:42

As we all know, China's total water resources are relatively rich, but due to the large population, the per capita water resources amount is only 28% of the world's per capita. With China's economic and social development and population growth, the contradiction between supply and demand of water resources has become increasingly prominent, especially the widespread water pollution, which aggravates the contradiction of water shortage.
Industry insiders believe that in theory, external and internal measures can be taken to solve the problem of regional water shortage.
External measures, in short, are to input water from external space, that is, to increase precipitation, but with little possibility, it is necessary to change the atmospheric circulation in a large scale or to make the climate change among regions; the other is to transfer water from engineering projects or input water through product crops. Project water transfer is currently more external measures, and it is also the most easily thought of measures, but it must not affect the change of water ecological environment in the water source area. The input of crops or industrial products can be equivalent to the input of some water (i.e. virtual water). However, due to the exchange between regions, the input and output are almost equal, and the water volume is relatively small, which can be ignored.
Internal measures, that is, to improve the water use efficiency within the regional scope, to achieve efficient utilization of water circulation, and further tap the water potential, the best way and method is to save water.
Water saving measures to correct the waste of water in society. "Water, inexhaustible, inexhaustible", affected by this, people lack the understanding of cherishing water and ignore the precious value of water, resulting in many bad behaviors of wasting water: long-term running water in life, high consumption and pollution of water in production, running, emitting, dripping, leaking and wasting water in pipelines for a long time. The implementation of water-saving measures can correct people's behavior of wasting water, so that people can cherish and cherish water, and let the limited water resources play an infinite value of production, life and ecology.
Water is not inexhaustible. We should cherish every drop of water. Saving water and conserving water resources requires public participation and everyone starts to save every drop of water. Water saving priority is the only way to ensure water security and a key choice for sustainable development of the Chinese nation.
