A multicriteria assessment of vulnerability to extreme rainfall events on the Pacific coast of Mexico

This research paper presents a multicriteria assessment of vulnerability to extreme rainfall events (ERE) at the municipal level in the coastal state of Sinaloa, Mexico, using socioeconomic and environmental indicators to identify the most at-risk areas.

• The study utilized a vulnerability model based on two main categories: response capacity (comprising Economic conditions, Social development, and Living standards) and severity (comprising Geographic exposure and Risk intensifiers). Using an analytical hierarchical process (AHP), Geographic exposure (0.43) and Economic conditions (0.34) were identified as the primary determinants of vulnerability.
• Based on standardized values and the integral vulnerability index (IVI), the municipalities of Guasave in the north and Escuinapa in the south were identified as the most vulnerable, with standardized scores exceeding 9.0 and IVI scores of 3.73 and 3.15 respectively. Conversely, the central municipalities of Culiacán and San Ignacio were the least vulnerable, with standardized scores below 5.5.
• While the coastal population was the primary determinant of vulnerability with a median of 0.57, the increase in IVI scores was also driven by other indicators related to response capacity and severity.
