China conducted a large-scale soil quality sampling analysis nationwide from 2005 to 2013, [83] and according to the National Soil Pollution Survey Bulletin promulgated by the Ministry of Environmental Protection of China in 2014, the total national soil exceedance rate (the percentage that exceeds the upper limit value) was 16.1%, of which ...
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.
As stated by Shixiong Cao of China’s Agricultural University, “Planting trees in arid and semiarid regions of China has led to increased environmental degradation and impacts on soil moisture, hydrology, and vegetation coverage.” [10] The large production of monocultural forests have led to the rapid desertification of areas that have ...
The vast majority of China's cultivated land lies in eastern China.Nearly all of the arable land, totaling 122 million hectares or 13% of the country, is cultivated. [5] To ensure adequate food production, the government has identified a minimum threshold or “redline” of 120 million hectares of cultivated land. [6]
Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
China's soybean yields at 1.99 tons per hectare lag the 3.38 and 3.4 ton-yields in Brazil and the U.S., which have embraced genetically modified soybeans. But analysts say the government's target ...
The immense population growth in the People's Republic of China since the 1980s has resulted in increased soil pollution. [citation needed] The State Environmental Protection Administration believes it to be a threat to the environment, food safety and sustainable agriculture. 38,610 square miles (100,000 km 2) of China's cultivated land have been polluted, with contaminated water being used ...
These storms have serious agricultural impacts on other nearby countries, including Japan, North Korea, and South Korea. [8] The Green Wall project was begun in 1978, with the proposed result of raising northern China's forest cover from 5 to 15 percent, [9] thereby reducing desertification.
