Problemas ambientais urbanos em São João do Piauí PI

Abstract

Environmental issues are among the most widely discussed topics today due to their significant global impacts. In recent years, rapid urban expansion has altered natural landscapes and affected environmental quality and living conditions. Within this context, solid waste management, air, water, and soil pollution, as well as inadequate sanitation, stand out as major concerns. The objective of this study was to map the areas most affected by environmental problems in the urban area of São João do Piauí and to identify environmental impacts resulting from human activities in different neighborhoods, while proposing strategies to mitigate the observed problems. This research adopted a qualitative-quantitative and descriptive approach, combining field surveys, the production of thematic maps using QGIS software (version 3.44.8), and the Check List technique (Oliveira, 2014; Costa, 2021) to assess the identified environmental impacts. The results identified nine critical locations within the urban area of São João do Piauí, characterized by serious environmental problems, including open dumping of solid waste, flooding during the rainy season, riparian vegetation degradation, untreated sewage discharge, and inadequate waste disposal practices. These impacts were classified as having high magnitude and long-term duration, highlighting the urgent need for structural interventions by public authorities
