Hazards of desertification

The hazards of desertification are: the productive potential of land is declining, and the biological productive potential of land is gradually attenuated and disappeared by land desertification; Land productivity declines; Grassland quality is declining. Due to the harm of land desertification, the development of animal husbandry has been hindered for a long time, and many areas have a downward trend.

Desertification is a natural (unnatural) phenomenon in which the productivity of large areas of soil is reduced or lost due to drought, lack of rain, vegetation destruction, overgrazing, wind erosion, running water erosion, soil salinization and other factors. The word "desertification" began to spread. The final result of desertification is mostly desertification. Desertification control needs extensive international cooperation and the participation of all countries in the world.

Desertification and poverty aggravate each other and form a vicious circle. In the short term, poverty will lead to more unreasonable use and development of land and natural resources. At the same time, desertification threatens food production, affects biodiversity, affects political stability, leads to migration, and causes and aggravates poverty.
