In the United States, the annual cost of soil erosion for both on-site and off-site effects has been estimated at 44 billion dollars a year (Pimentel et al., 1995). In the European Union, the figure is 38 billion Euros a year (Montanarella, 2007).
Data from the 2003 Annual NRI, the most up-to-date NRI information available, indicate that average soil erosion rates on all cropland and CRP land have decreased more than 38 percent since 1982. In 2003, the soil erosion rate was estimated at 4.5 tons per acre per year, compared to 7.3 tons per acre per year in 1982.ata from the 2003 Annual NRI, the most up-to-date NRI information available, indicate that average soil erosion rates on all cropland and CRP land have decreased more than 38 percent since 1982.
