Although desertification has been curbed in some areas, it is still expanding at a rate of more than 67 km 2 every year. 90% of China's desertification occurs in the west of the country. [27] Approximately 30% of China's surface area is desert. China's rapid industrialization could cause this area to drastically increase.
A study pointed to China's deforestation and soil erosion as indirect effects of the nation's booming population. [7] High population growth in China has led to increasing demand for wood for housing and furniture as well as for firewood for cooking and heating.
South America is another area vulnerable by desertification, as 25% of the land is classified as drylands [73] and over 68% of the land area has undergone soil erosion as a result of deforestation and overgrazing. [74] 27 to 43% of the land areas in Bolivia, Chile, Ecuador and Peru are at risk due to desertification. In Argentina, Mexico and ...
[13] [4] Erosion of soil becomes a bigger problem, since no longer are there as many plants to anchor in the soil. In the northern Chinese province alone, 400 million are affected every year with an associated 54 billion yuan of annual economic loss due to grassland degradation.
In total, nearly 16.1% of China's soil was polluted. [79] These pollutions have caused a serious impact on the growth of crops and the health of the people. [ 80 ] In terms of related policies, the Chinese government decided to draw on the successful examples of other countries and integrate China's national conditions to maintain long-term ...
The Great Green Wall, officially known as the Three-North Shelter Forest Program (simplified Chinese: 三北防护林; traditional Chinese: 三北防護林; pinyin: Sānběi Fánghùlín), also known as the Three-North Shelterbelt Program, is a series of human-planted windbreaking forest strips (shelterbelts) in China, designed to hold back the expansion of the Gobi Desert, [1] and provide ...
Soil erosion is the main factor for soil degradation and is due to several mechanisms: water erosion, wind erosion, chemical degradation and physical degradation. Erosion can be influenced by human activity. For example, roads which increase impermeable surfaces lead to streaming and ground loss.
Deforestation in China's Loess Plateau many years ago has led to soil erosion; this erosion has led to valleys opening up. The increase of soil in the runoff causes the Yellow River to flood and makes it yellow-colored. [207] Greater erosion is not always a consequence of deforestation, as observed in the southwestern regions of the US.
