Vulnerabilidade socioambiental em áreas de risco para enchentes: estudo de caso da rua Cedro no bairro Poti Velho

Abstract

This paper considers the socio-environmental effects of flooding in the Poti Velho neighborhood, in the city of Teresina-PI. With the advent of urbanization and urban growth, these are accompanied by socio-environmental problems due to the lack of planning of land use and occupation, with occupation in areas considered to be at risk of flooding by the population in a situation of socio-environmental vulnerability, being directly impacted with human and material losses, among others. The general objective of this study is to analyze the phenomenon of flooding on Cedro Street caused by the Poti and Parnaíba rivers, in the Poti Velho neighborhood, in the northern region of Teresina, in 2022. The specific objective is to learn about and identify the socio-environmental impacts resulting from these floods, suggesting educational environmental measures to minimize the negative impacts involving the area under study, as well as addressing the concepts and consequences of socio-environmental effects. A qualitative/quantitative methodology was used, with the following methodological procedures: bibliographical research in theses, articles, dissertations and books and documentary research with the analysis of documents from public bodies, a field study with interviews with managers of municipal departments and the application of questionnaires to residents of the area under study. It was concluded that the areas most susceptible to events are located along Boa Esperança Avenue and Cedro Street, which is a confluence point between the Parnaíba River and the Poti River. According to the sectorization, the area is classified as being at very high risk, and several socio-environmental impacts were identified, such as loss of housing, materials, work, proliferation of diseases, as well as contamination of the river through effluents and solid waste.
