Science, 1995•science.orgSoil erosion is a major environmental threat to the sustainability and productive capacity of
agriculture. During the last 40 years, nearly one-third of the world's arable land has been lost
by erosion and continues to be lost at a rate of more than 10 million hectares per year. With
the addition of a quarter of a million people each day, the world population's food demand is
increasing at a time when per capita food productivity is beginning to decline.
