Analysis evolution of environmentally sensitive areas to desertification in the Puangue river basin Chile

Abstract

Desertification is a silent process that affects the mediterranean region in central Chile. This study analyzes the evolution of environmental sensitivity to desertification in the Puangue river basin in the Metropolitan Region of Santiago de Chile. The model developed by the MEDALUS project (Mediterranean Desertification and Land Use) is used in the study area. It is concluded that the sensitivity to desertification has increased in the last 30 years. The foregoing mainly due to the impact of the change of use to agriculture in the mountain sectors.
