Causes and Countermeasures of Desertification in Central Asia

The causes and measures of desertification in Central Asia are as follows:

Land desertification is a phenomenon caused by drought and lack of rain, vegetation destruction, overgrazing, wind erosion, running water erosion, soil salinization and other factors.

Countermeasures and measures for desertification control;

1. To prevent and control desertification, it is necessary to protect existing vegetation and strengthen forest and grass construction. At the same time, it is necessary to solve the problems of population, livestock and stoves, protect forest and grass vegetation in sandy areas, rationally allocate trees, shrubs and grass through afforestation, expand the proportion of forest and grass, and establish a multi-forest, multi-tree and multi-level three-dimensional protection system.

2. While artificially controlling desertification, we should give full play to the self-repair function of the ecosystem, increase the intensity of closure and protection, and enhance the ability of ecological natural restoration. Because aerial seeding has the characteristics of high speed, less labor, low cost and good effect, it can help to restore vegetation in remote deserts and barren hills with vast land and sparse population and inconvenient transportation, and vegetation can be planted by aerial seeding.

3. Desertification areas can carry out a lasting ecological revolution and accelerate the reversal of desertification process. The key is to rationally allocate water resources and ensure ecological water use. Usually, the unreasonable allocation of water resources is the direct cause of shortening rivers, shrinking lakes or even drying up, lowering groundwater level and land desertification in northwest China.

4. Strictly implement the family planning policy, control the population growth rate, prevent the population from growing too fast, continuously improve the quality of the population, carry out environmental awareness publicity and education lectures, and improve people's ideological level. Care for the environment at ordinary times, consciously participate in the transformation and construction of the environment, and form a good social atmosphere.

5. The state needs to implement the ecological migration policy in areas where desertification is very serious, grasslands and cultivated land are almost completely abandoned, and the harsh natural environment is no longer suitable for human survival.
