ABSTRACT
The loss of soil from land surfaces by erosion is widespread globally and adversely affects the productivity of all natural ecosystems as well as agricultural, forest, and rangeland ecosystems (Lal and Stewart, 1990; Pimentel, 1993; Pimentel et al., 1995; Pimentel and Kounang, 1998). Concurrent with the escalating human population, soil erosion, water availability, energy, and loss of biodiversity rank as the prime environmental problems throughout the world.
