Abstract: Erosion mapping is essential for the knowledge of the distribution and geography of erosive processes as well as for its quantitative characterization. The methodology used in this paper is a basis for identifying areas with high erosion risk. It also makes possible to study the impact of future changes in environmental conditions.In this paper, the general qualitative scheme proposed by PAP/RAC (1997) is applied, modified by adding the evaluation of rainfall erosivity. Possible future changes in land cover have been considered, analysing three different situations. The results show that a great part of the studied area presents a high erosion risk due to the relief. However, the protection by vegetation is high enough to protect soil from rainfall erosion. Wrong decisions in forest management might lead to increasing potential erosion problems in the area. El estudio del riesgo de la erosión es esencial para el conocimiento de la distribución geográfica de los fenómenos erosivos y para su caracterización cuantitativa. La metodología usada constituye una base para identificar las áreas en riesgo de e...
