Cuantificación de vulnerabilidad y riesgo: las inundaciones en Motozintla de Mendoza, Chiapas, México

Abstract

The central objective of this research was to develop a methodology for the quantification of global social vulnerability. The methodology is used to determine the risk of flooding in Motozintla. However, such methodology can be replicated in others communities in Mexico.  The methodology consisted in the following steps: (a) the cartographic actualization of the urban layout of Motozintla; (b) the establishment and characterization of a minimal sample of households for this study; (c) selection of variables for the identification of different types of vulnerabilities (structural, socio-economic, organizational, and perception of risk) and global vulnerability (all variables of the analyzed vulnerabilities considering a level of weighted incidence); (d) use of the interpolation method, Inverse Distance Weighting (IDW), to identify areas and levels of vulnerability and risk; and (e) use of a Geographic Information System for cartographic representation of the results and their spatial analysis.
