Estudio exploratorio de la calidad ambiental en entornos urbanos, caso de estudio de la ciudad de Portoviejo

Abstract

Abstract: This project aims to assess the environmental quality of Portoviejo using the Urban Environmental Quality Index (UENQI), developed from remote sensing data. To formulate the UACI, three key indicators were analyzed: Normalized Vegetation Index (NDVI), Surface Temperature (SST), and Building Density (BD). In addition, a cluster analysis was performed based on environmental quality and census socioeconomic data to prioritize areas and propose improvement strategies. The results reveal that, in general, environmental quality in the peripheral sectors of the city is positive; however, central areas have the lowest values ​​due to high building density, higher population concentrations, and high temperatures, with limited vegetation cover. The UACI was also compared with the presence of air pollutants, identifying vehicular traffic and cultivated areas as the main sources of pollution. Although the resolution of satellite data does not capture microenvironmental changes, these findings can be used by local authorities to optimize urban planning and improve the sustainability of urban areas. the city.
