Fortaleciendo el uso de los instrumentos de planificación urbana, para la gestión de riesgos. Ciudad de Coronel, Región del Biobío

Abstract

In developing countries, the migration to unplanned urban settlements located in areas exposed to natural hazards has increased the vulnerability of the population to socionatural disasters. In Chile, the variable of risk has been included in territorial planning instruments through studies on land use zoning. In order to promote the use of the information generated by risk management initiatives, the authorities of Coronel identified risk areas through spatial analysis intended to determine the distribution and exposure of local dwellers. The results show that 67.2 percent of urban land is prone to socionatural disasters, which may affect 18.4 percent of the local population.
