In 1980s, desertification area is 560km2 and sandstorms occurred 8 times. But in1990s, the area shoot up to 810km2, sandstorms came 12 times. After ten years, desertification area increased to 980km2, equivalent to a China. The situation is critical.
So what cause this problem? One side, the change of climate can lead to desertification. But desertification may mostly create by human.

Secondly, carry out land intensive operation, no excessive grazing, advocate rotation tillage, fallow, maintain soil fertility. In addition, land degradation, desertification region, people should change consciousness, to alleviate the situation of living off the land; the area also should adjust industrial structure, develop agriculture energetically than some high economic value added of industry, save the precious water resources, to better manage the desertification.
