Determinants of Soil Loss Tolerance

The world population is expected to increase from approximately 4.5 billion in 1980 to 6.3 billion in the year 2000 if the present rate of population growth does not change. The world's food production must increase at the rate of 2% per year to maintain the same food supply/population ratio we have today, but even more would be needed to improve diets in developing countries. At the same time that increased food production is needed, millions of acres of land are being subjected to major soil erosion losses. This combination of events has led many to conclude that losses in soil productivity due to erosion are such that we will not be able to maintain current levels of agricultural production, much less meet the growing needs of the future.
