Desertification is a serious global problem, already effect many people’s life. Desertification and Land degradation is a gradual process, but its hazards and disasters are lasting and far-reaching. This issue is caused by two main reasons, natural factor and human factor. The human factor is main cause.

The population growth and economic development put too much pressure on the land. Excessive reclamation, overgrazing, deforestation and unreasonable use of water resources seriously degraded the land, destroyed the forest, and gradually dried up the climate, eventually forming a desert.

Arid and semi-arid areas are already short of water and windy, now the land is ravaged, vegetation destroyed, less precipitation, more wind erosion topsoil, sand slowly dune development. This makes arable and pastoral land, into not suitable for grazing and farming desertification land.

Desertification is a sign of environmental degradation and a positive feedback process of environmental instability. If no fundamental measures are taken, the land erosion and desertification process will not automatically stop but will intensify development.
