I studied on land degradation and desertification in Mongolia this time.
< Land Degradation >
- A degradation of ecosystem in Mongolia is still being obstacle for its socio-economic development and economic stabilization.
- A total area of the damaged or depleted land is estimated to be 121.7 million hectares, of which:
- 91.7 million hectares are by the combination of wind and water;
- 21.1 million hectares by water;
- 7.9 million hectares are covered by sand
Main human causes of land degradation are:
- Mining is one of the rapidly growing and leading industry branches
in Mongolia causing substantial soil destruction. No proper
rehabilitation measures during and after mining.
- Overgrazing specially around settlement areas and water points, etc.
- Nearly half of the total farmland is out of use and abandoned.
< Desertification (Climate Change, Dust and Sand Storms) >
Mongolia is a country, which experiences serious drought and desertification.
- More than 40% of the territory is composed of arid and desert areas
- 70% degraded at certain rate
- 90 % of the total territory a subject to desertification.
Current desertification has three main directions: 1) Desertification of vegetation cover, 2) Desiccation of wetland ecosystems and 3) Increase of sand area.
