According to the characteristics of water cycle, what measures should be taken to improve the arid climate in a place?

Water cycle refers to the continuous movement of natural water in hydrosphere, atmosphere, lithosphere and biosphere through evaporation, plant transpiration, water vapor transport, precipitation, surface runoff, infiltration and underground runoff.

The role of green plants in forests and grasslands participates in the water cycle in the biosphere, such as increasing atmospheric temperature and precipitation through transpiration. The stems and leaves of plants can buffer the erosion of rain on the ground, and the litter can absorb a lot of rain and replenish groundwater.

Measures to improve the arid climate:

Improve irrigation facilities and use irrigation machinery. Most areas in southern China are rich in water resources, and drought is an engineering water shortage, not a resource water shortage. The construction of water conservancy irrigation facilities is very helpful to solve the rice drought, and it is also helpful to adopt new varieties with high yield and high quality in the local area.

Digging at the lowest point of the dry river bed and the lowest point of the sand dunes may find groundwater. Fresh water can be obtained by condensation.

Irrigation according to the water demand law of rice can greatly improve the utilization efficiency of irrigation water and reduce the waste of water.
