Land use in China
China has four times the population of the U.S., within roughly the same area. With 1.3 billion inhabitants, 20% of the world’s population lives in China. While the rate of population growth has been declining for decades, the total number of inhabitants has been growing and is expected to do so through 2030. China’s urban population is growing rapidly; between 1950 and 2009, the percentage of the population living in urban areas quadrupled from 14% to 48%. Meanwhile, the rural population is declining, opening the landscape in areas that are not urbanized. The forests and farming land of eastern China support far more people and major cities than do the grasslands, deserts, and high mountain regions of the west.
China
In recent decades, China has suffered from severe environmental deterioration and pollution. While regulations such as the 1979 Environmental Protection Law are fairly stringent, they are poorly enforced, as they are frequently disregarded by local communities and government officials in favor of rapid economic development. Urban air pollution is a severe health issue in the country; the World Bank estimated in 2013 that 16 of the world's 20 most-polluted cities are located in China. And China is the country with the highest death toll because of air pollution. There are 1.14 million deaths caused by exposure to ambient air pollution. China is the world's largest carbon dioxide emitter. The country also has significant water pollution problems: 40% of China's rivers had been polluted by industrial and agricultural waste by late 2011. In 2014, the internal freshwater resources per capita of China reduced to 2,062m, and it was below 500m in the North China Plain, while 5,920m in the world.
