China is severely affected by desertification, with more than a quarter of its territory covered in desert. As of 2010, 57% of its territory, or 2.97 million hectares, had been affected by desertification. The encroaching deserts threaten to destroy farmland and bury villages, forcing people to abandon their homes.
What has caused desertification in China?
China’s most underdeveloped counties are located in decertified areas. 1.4 The major causes of land desertification in China are climate change and human economic activities. Soil loss due to wind erosion was ten to 15 cm, and sand loss, 20 to 150 cm for a total economic damage of 560 million RMB yuan.
What is China doing about desertification?
To control this soil erosion, various soil conservation programmes consisting of terracing, construction of check dams, and vegetation restoration, notably afforestation, have been implemented by the Chinese government since the 1950s.
Why did China cut down trees?
Water shortages. There are some pitfalls to mass tree planting. In southwestern China, researchers have found that farmers were cutting down native vegetation so they could collect money for sowing non-native plants in government programmes4. Then there are water shortages.
How does China affect climate change?
The country is the world’s largest emitter of greenhouse gases, and coal in China is a major cause of global warming. However, from 2010 to 2015 China reduced energy consumption per unit of GDP by 18%, and CO2 emissions per unit of GDP by 20%.
Where is desertification occurring today?
Africa is the simple answer to the question: where is desertification happening? More specifically, desertification plays its largest role in the grasslands of East Africa, the Kalahari Desert and the Sahara Desert. These regions span over 65 percent of the land.
What has caused desertification in China and what are the consequences?
These regions have suffered from climate change, unfavorable hydrologic conditions, changes in vegetation composition, loss of soil services and desertification; the combination of these effects has generated many adverse consequences, including sandstorms that threaten ecosystem services and human life2.
What is China doing about climate change?
China’s government is taking some measures to increase renewable energy, and other decarbonization efforts, vowing to hit peak emissions before 2030 and be carbon neutral by 2060 by adopting “more vigorous policies and measures.”
Does China have a deforestation problem?
China Deforestation Rates & Statistics | GFW. In 2010, China had 133Mha of natural forest, extending over 16% of its land area. In 2020, it lost 328kha of natural forest, equivalent to 131Mt of CO₂ of emissions.
How much of China is desert?
Mountains cover 58 percent of China. Deserts cover 28 percent. Plains and basins cover around 35 percent. Based on 2005 estimates, 14.86 percent (about 1.4 million square kilometers) of China’s land is arable.
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 the reason for desertification in China?
Causes of modern desertification in China 5.1. Variations in wind activity. Wind activity is a key factor that controls aeolian geomorphological processes, dust transportation and deposition, and desertification in arid and semiarid China. 5.2. Variations in spring precipitation. 5.3. Dune mobilization. 5.4. Human impacts on desertification.
What is desertification is caused by?
Desertification is caused by a combination of factors that change over time and vary by location. These include indirect factors such as population pressure, socioeconomic and policy factors, and international trade as well as direct factors such as land use patterns and practices and climate-related processes.
