Abstract
This study analyzed the sensitivity to desertification in the province of El Oro from 1990 to 2020, focusing on the region's productivity and economic resources. The main objective was to conduct a multi-temporal assessment of this phenomenon. To this end, Landsat 7 and 8 satellite imagery was used, along with software such as ENVI and ArcMap 10.8 to classify land use. Climate data from the National Institute of Meteorology and Hydrology (INAHMI) were collected, analyzing temperature, precipitation, and evaporation. The study was validated using a confusion matrix, achieving 93% reliability in 2020. During the study period, a 32.13% change in land use was recorded, compared to 67.86% that remained unchanged. In conclusion, the analysis identified areas with high susceptibility to desertification in the cantons of Machala, Chilla, Balsas, Pasaje, and El Guabo, covering 277,383.25 hectares. Areas with low susceptibility were found in Arenillas, Las Lajas, Marcabelí, and Portovelo, with 130,458.37 hectares, while medium susceptibility corresponded to Atahualpa, Piñas, Zaruma, and Huaquillas, with 166,445.78 hectares.
