Objective: Since the beginning of this century, the municipality of Brusque has recorded a significant increase in landslide occurrences, which have caused both serious damage to the city's infrastructure and fatalities. This article aims to classify the socio-environmental vulnerability (SEV) of the municipality of Brusque, in the state of Santa Catarina (SC), to socio-environmental disasters (landslides).
Methodology: The SEV mapping was developed from a multi-criteria analysis with the aid of a geographic information system (GIS). In order for the SEV classification to function, it was necessary to calculate the propensity (Ivs) and exposure (VAT) indices. The indices were cross referenced in a social and environmental vulnerability matrix.
Originality/Relevance: The relevance of the study is justified by evaluating the methodology that not only considers the physical natural environment, but also the ability of the community to prevent, absorb, resist/respond and adapt to socio-environmental disasters.
Main Results: The results have classified Brusque as a municipality of high socio-environmental vulnerability to landslides. This classification indicates a pattern of high environmental susceptibility with an increased number of inhabitants living in risk areas.
Contributions: This article aims to contribute through advances in evaluation research and the formulation of integrated risk and resilience management proposals in the municipalities of Vale do Itajaí/SC/Brazil. In this context, it is important to understand scenarios with the greatest impact of socio-environmental disasters as a tool for urban planning and disaster risk management in the city of Brusque/SC
Keywords: socio-environmental disasters; environmental vulnerability; impact; mass movements; Brusque.
