Indicadores da qualidade ambiental urbana no bairro Vale Quem Tem, em Teresina, Piauí

Abstract

Cities constantly change land use to meet the needs of their inhabitants, such as housing, education, sanitation, leisure, etc. This waterproofs the soil, expands the built areas, and reduces vegetation. This situation affects the landscape, urban dynamics, and the environment, reducing the urban environmental quality (QAU), which needs to be evaluated. This study aimed to diagnose the QAU of the Vale Quem Tem neighborhood in Teresina-Piauí, Brazil. For this, concepts related to the theme were discussed, identified, and mapped environmental indicators in the neighborhood. The methodology of Nucci (2008) was adapted, using primary data, field research by direct and indirect observation, secondary data, bibliographic research, legislation, and census sources. Indicators such as land use, pollution, risk points, demographic density, verticality, free spaces, and vegetation were used. The data were represented in the Quantum Gis software. The results showed that Geovane Prado and Taquari have QAU ranging from high to very high, while Planalto Uruguay and Mão Santa Park (PMS) vary from high to medium quality. It was observed that the PMS lacks green areas and vegetation in public leisure spaces and presented in two dense nuclei with a very low QAU. The central area of the neighborhood has quality ranging from medium to high. The diagnosis reveals that the neighborhood’s IAQ is compromised by its varied uses of soil. This study can contribute to the public power to promote effective interventions in land use and the improvement of the natural environment. Keywords: Urban Planning; Development; Sustainability.
