Objective: To map and classify the socio-environmental vulnerability of regions in the municipality of Blumenau (SC) to socio-environmental disasters (floods and landslides) through the construction of a socio-environmental vulnerability index (SEVI) for the period 2000-2020. Method: The SEVI map was developed from a multicriteria analysis with the aid of a geographic information system (GIS). For the SEVI to operate, it was necessary to prepare the indices of environmental susceptibility (ES) and social vulnerability (SV), which were then cross-referenced in an impact matrix. Relevance: To develop a methodology for assessing the socio-environmental vulnerability to disasters, which considers issues related both to the local natural environment and to the ability of social groups to resist/respond to disasters. Results: The results have indicated an increase in informal settlements in permanent preservation areas, environmental degradation, social inequality and consequently a population exposed to risk. In short, Blumenau presents a pattern of high susceptibility and an exacerbated increase in social vulnerability, which thereby configures a highly vulnerable scenario for socio-environmental disasters. Contributions: Advances made in evaluation research and in formulating integrated management proposals for risk and resilience in the municipalities of Vale do Itajaí/SC/Brazil. In this context, it is essential to understand the scenarios with the greatest impact of socio-environmental disasters, as a tool for urban planning and disaster risk management in the municipality of Blumenau (SC).
