Análisis de la influencia de los cambios de uso del suelo y vegetación en la ocurrencia de deslizamientos de ladera en la región Zoque, norte de Chiapas, México

Landslides are among the phenomena that have caused significant material and human losses worldwide, largely due to the reduction of vegetation andchanges in land use driven by human activities. The frequency of hurricanes in Mexico further accelerates these events by increasing precipitation accumulation. This study examines the impact of land use and vegetation changes on the susceptibility to hillside processes in the Zoque region of Chiapas, following the major landslides caused by Hurricane Eta in 2020. Changes in land use and vegetation between 1986 and 2020 were analyzed, and the region's susceptibility was subsequently modeled based on conditioning factors such as lithology, land use and vegetation, slope, and drainage density. The spatial analysis revealed that areas with the steepest slopes, where the most significant land use and vegetation changes had occurred, were the most susceptible to landslides. Deforested regions used for agriculture and livestock farming showed medium, high, and very high susceptibility, which were widespread throughout the area. This study is one of the few to identify landslide susceptibility in the region, and the results aim to support planning efforts for risk prevention and mitigation.
