The risk of erosion and soil loss on geomorphological landscape units volcanic origin in the Mololoa river basin, Mexico, is evaluated, applying universal equation loss, with support geographic information systems. natural resources this part Nayarit territory have favored economic development establishment state capital; However, relationship, lacking a planning that incorporates environmental criteria, has had an accelerated deterioration them, above all soils, which time can translate into low levels well-being for users territory. results show 57.6% landscapes study area present very high erosion, corresponding to Sierras de San Juan Volcan, mountain slopes, associated volcano Sanganguey slopes Tepeltitic volcano. On other hand, 66% under some level affectation due water erosion; 13.7% surface basin presents significant problems (very high); 16.6% presented moderate 35.7% losses less than 10 t per year.
