Objetivo de estudio: Desde el comienzo de este siglo, el municipio de Brusque ha registrado un aumento significativo en las ocurrencias de movimientos de masa, que han causado graves daños a la infraestructura de la ciudad y han provocado muertes. El artículo tiene como objetivo clasificar la vulnerabilidad socioambiental (SAV) de los sectores censales de la ciudad de Brusque (SC) a los desastres socioambientales (movimientos en masa).
Metodología: El mapa VSA se desarrolló a partir de un análisis multicriterio con la ayuda del Sistema de Información Geográfica (SIG). Para el funcionamiento de la clasificación VSA, fue necesario realizar cálculos para la constitución de los índices de propensión (Ivs) y exposición (Iva). Los índices fueron cruzados en una Matriz de Vulnerabilidad Socioambiental y aplicados al mapa de sectores censales en el municipio de Brusque.
Originalidad/Relevancia: La relevancia del trabajo de estudio se justifica por el desarrollo de una configuración en el uso de nuevas metodologías para la evaluación de la vulnerabilidad socioambiental a los desastres, que consideran no solo las cuestiones del entorno natural local, s lugares, pero también la capacidad de ciertos grupos para prevenir, absorber, resistir/responder y adaptarse a los desastres socioambientales.
Principales Resultados: Los resultados clasifican al municipio de Brusque como de alta vulnerabilidad socioambiental a los movimientos masivos. Clasificación Los resultados apuntan a un patrón de alta susceptibilidad ambiental y un aumento progresivo de la población en vulnerabilidad social, ubicada en áreas de riesgo. Estos resultados configuran al municipio como altamente vulnerable a los movimientos masivos.
Contribuciones: este artículo tiene como objetivo contribuir a través de avances en la investigación de evaluación y formulación de propuestas de gestión integrada de riesgos y resiliencia en los municipios de Vale do Itajaí/SC/Brasil. En este contexto, es importante comprender los escenarios y áreas con mayor impacto de desastres socioambientales, para su mapeo como herramienta para la planificación urbana y la gestión del riesgo de desastres en la ciudad de Brusque/SC.
Palabras clave: movimientos de masas; vulnerabilidad socioambiental; desastres socioambientales; impacto; brusco.
