During the mining process, a large area of land will be encroached upon, resulting in the loss of soil resources and destroy the crust layer. The destruction of soil caused by mining activities in arid areas is mainly reflected in four aspects: (1) The water washing measures in the gold mine area stripped and destroyed the soil and vegetation.

These climates (arid and semi arid) cover nearly 26 percent of the earth's land area of which 12 percent is under arid climates. Grass lands of semi arid climates are cultivated in a very organized manner and the resources of arid climates are also extracted vigorously. Problems of ecological imbalances are noticed in these climates.
