How does desertification affect the environment?
Desertification makes natural disasters worse because it reduces natural resilience of ecosystems. Desertification also increases vulnerability of whole regions to the unpredictable effects of climate change. Events such as flash floods, landslides and dust storms, become stronger in areas with heavily degraded soils.
What has caused desertification in China?
Desertification in China is caused largely by overgrazing. Huge flocks of sheep and goats strip the land of vegetation. In Xillinggol Prefecture in Inner Mongolia , for example, the livestock population increased from 2 million in 1977 to 18 million in 2000, turning one third of the grassland area to desert.
What is China doing to prevent the desertification of its land?
China is taking some steps to address desertification with crop cover and with plans to plant trees along the border of the Gobi Desert to help decrease dust storms and desertification. China and Africa face some of the most severe challenges. Controlled grazing can also help.
What is the reason for desertification in China?
In general, the results of systematic monitoring, and analyses of the causes of desertification and the contemporaneous human impacts, suggest that desertification in China has been primarily caused by climate change , and particularly by strong wind regimes (with high sand transport potential) accompanied by decreased spring precipitation.
