10.1 MAGNITUDE AND ECONOMIC IMPACTS OF SOIL EROSION
Soil erosion and resulting sedimentation problems continue to be major concerns
throughout the world. Dregne (1972) evaluated the general state of soil and land
degradation worldwide in the 1970s. Much of Southwest Asia, large areas of China,
India and Southeast Asia, Northern Africa, Central America, and Mexico suffer
* Helpful review comments have been provided by OSU colleague and former Chief of Soil and Water,
Ohio DNR, David Hanselmann. This paper will appear as an invited chapter in the forthcoming book
Advances in Soil Science , with a focus on principles of sustainable soil management in agroecosystems.
