Análise espacial do descarte irregular de resíduos sólidos urbanos nos bairros Aeroporto I e II em Corrente – Piaui

Abstract

This study analyzes the occurrence of irregular disposal of urban solid waste (RSU) in the neighborhoods of Aeroporto I and II, located in the municipality of Corrente, Piauí, Brazil. The objective was to understand the spatial distribution of disposal sites, characterize the types of waste identified, and investigate the factors associated with this socio-environmental issue. The research is descriptive and exploratory, adopting a qualitative and quantitative approach, developed through field visits, georeferenced photographic records, and the production of thematic maps using geographic information systems. A total of fifty-nine irregular disposal points were identified, with greater concentration in the Aeroporto II neighborhood. Spatial analysis revealed a correlation between disposal sites and areas characterized by vacant lots, unpaved streets, and segments adjacent to the state highway. Regarding waste characterization, there was a predominance of non-hazardous waste originating from household, commercial, pruning, and construction activities, as well as the punctual presence of hazardous waste and frequent open burning practices. The findings indicate that addressing this issue requires integrated planning, institutional strengthening, continuous environmental education, and the implementation of municipal waste management instruments to improve environmental quality and local living conditions.
