Resilience to disasters in coastal cities: a study of socio-environmental vulnerability in Itajaí
Abstract
The municipality of Itajaí, located on the northern coast of Santa Catarina, has an extensive history of disasters, particularly due to the frequent flooding that affects the region. This reality is exacerbated by climate change, which intensifies rainfall patterns and poses the threat of rising sea levels. In this context, the general objective of the article is to classify socio-environmental vulnerability to floods and mass movements in the municipality of Itajaí (SC), aiming to develop disaster resilience strategies. The methodology employed is a case study, utilizing a quantitative, descriptive, and evaluative approach that explores aspects of vulnerability through the application of a bivariate classification model resulting from the construction of indices. The results reveal that approximately 48,000 inhabitants in Itajaí live in areas of high and/or very high socio-environmental vulnerability. There is also significant socio-spatial segregation, with low-income populations concentrated in small areas at high risk of disasters. In contrast, high-income populations reside in verticalized areas characterized by concentrated investments in risk mitigation. In summary, Itajaí faces a critical increase in vulnerability to disasters, being exposed to the adverse effects of climate change. Given this scenario, it is urgent to consider interventions in the Disaster Risk Management model to strengthen resilience and promote climate adaptation.
