      1.1. Controls on Erosion Rates Of the variables that control erosion rates (e.g., topography, vegetation, substrate erodibility, and climate/rainfall erosivity) vegetation cover is the one most susceptible to influence by humans (Owens and Slymaker, 2004; Restrepo, 2003, Thornes, 1994; Vis, 1991).

      overgrazing and use of marginal lands intensify erosion, and the intensification of the agriculture production also results in high erosion rates (Cerdà et al., 2009). The prediction of erosion and/or degradation typically involves the use of empirical models (Leh et al., 2013). The Revised Universal Soil Loss Equation (RUSLE) is 3513

      Erosion evidences are visible in a large part of the study area, particularly where the vegetation cover is not complete. A large part of the area, mainly the southwest and southeast facing slopes, is interested by sheet erosion.
