Agriculture, forestry and animal husbandry vigorously promote sprinkler irrigation and drip irrigation. Is this a way to save water?

Compared with traditional irrigation, sprinkler irrigation and drip irrigation reduce the evaporation and leakage of water in the channel because of 1; 2. Uniform irrigation reduces irrigation quota. So it saves water.

But this is a water-saving irrigation technology. If these technologies are used well, they can save water, but how can they save water if users keep the water pump on?

Therefore, if we only promote the equipment without the corresponding supporting irrigation system, the effect of water saving will be greatly reduced. While we are promoting drip irrigation and sprinkler irrigation, it is more important to promote a reasonable irrigation system.
