Resumen: This study examined the effects of land use change on the potential of soil loss in the upper-middle basin of the Mira River in Andean Ecuador in the years 1995 and 2017 and by the future year 2030. The study is based on modeling soil erosion and LULC change by applying GIS and remote sensing. RUSLE equation was used to quantify soil erosion rates, and CA-Markov chain analysis was implemented to forecast the LULC change for the 2030 year. The results showed that the annual average soil erosion passed from 14.72 t/ha/year to 32.78 t/ha/year and will probably achieve 41.01 t/ha/year by 2030. Between 1996-2018 and 2018-2030, the conversion and probable conversion towards bare soils and crops led to soil loss and unsustainable production rates by far greater than >10 t/ha/year. Some recommended measures to prevent soil erosion include restoring areas with scarce vegetation cover and integrating soil conservation measures with tillage practices and grazing activities. Practices such as strip cropping, contour cropping, building terraces on sloping areas, grazing regulation, or implying deep tillage and soil amendments are recommended
