“…The USDA [60] reports that 60% of water-eroded soil ends up in streams. In China, approximately 1-2 billion tons/year of soil was transported down the Yellow River into the Yellow Sea from 1950-1970 but since the late 1980s the sediment load has decreased due to better soil conservation practices on the Loess Plateau, and the greater use of Yellow River water for irrigation, human consumption and industrial uses [113][114][115]. The most costly off-site damages occur when soil particles enter lake or river systems [116,117].…”

Since humans worldwide obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and aquatic ecosystems, preserving cropland and maintaining soil fertility should be of the highest importance to human welfare. Soil erosion is one of the most serious threats facing world food production. Each year about 10 million ha of cropland are lost due to soil erosion, thus reducing the cropland available for world food production. The loss of cropland is a serious problem because the World Health Organization and the Food and Agricultural Organization report that two-thirds of the world population is malnourished. Overall, soil is being lost from agricultural areas 10 to 40 times faster than the rate of soil formation imperiling humanity's food security.

“…The USDA (1989) reports that 60% of the water-eroded soil ends up in US streams. Similarly in China, approximately 2 billion tons/year of soil are transported down the Yellow River in China into the Yellow Sea (Lal and Stewart, 1990;McLaughlin, 1993;Zhang et al, 1997). The most costly off-site damages occur when soil particles enter lake and river systems (Lal and Stewart, 1990;Martin, 1997;Watershed, 2002).…”

Soil erosion is one of the most serious environmental and public health problems facing human society. Humans obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and other aquatic ecosystems. Each year about 10 million ha of cropland are lost due to soil erosion, thus reducing the cropland available for food production. The loss of cropland is a serious problem because the World Health Organization reports that more than 3.7 billion people are malnourished in the world. Overall soil is being lost from land areas 10 to 40 times faster than the rate of soil renewal imperiling future human food security and environmental quality.
