Urban occupation and socio-environmental vulnerability in the Itacorubi Riversub-basin, Florianópolis, Brazil

Brazilian cities face significant challenges related to geo-hydrological hazards, which, due to socio--spatial inequality, affect social strata in different ways. Based on this observation, the objective of this study is to examine the relationship between mass movement and flood hazards, urban transformations, and the spatial distribution of social strata in the Itacorubi River sub-basin in Florianópolis, Brazil. Confirming the initial hypothesis, less privileged groups and the middle class are susceptible to geo-hydrological hazards present in the sub-basin. These findings confirm the differentiated nature of these hazards and the importance of conducting local studies at the watershed level to identify environmental vulnerabilities and support a planning process that takes socio-environmental interaction into account, promoting more sustainable land use.
