Corredores verdes: uma estratégia para o planejamento urbano e paisagístico de Teresina - PI como efeito mitigador de temperatura

Abstract

Vegetation plays an essential role in urban climate control, contributing to the reduction of temperature and the modification of the microclimatic conditions of cities. In this context, the Urban Green Corridors (CVUs) emerge as a sustainable solution for promoting connectivity between green spaces and urban infrastructure. Against this background, this study investigates the green corridors as an effective strategy for urban and landscape planning of Teresina-PI, considering its potential as a thermal mitigation mechanism. The research aims to analyze the impact of road arborization, through the green corridors, in promoting thermal comfort within the urban dynamics of the city. To this end, the methodology involved the investigation of the cooling effect generated by urban green areas, in wooded and unafforested places, through the collection of temperature and humidity data at eight distinct points along the road axis connecting the Green Neighborhoods Home and the Hawaiian Valley, located in the Eastern Zone of Teresina-PI. The analyses covered the months from August to November 2024, for seven consecutive days of each month, and considered the Thermal Discomfort Index (IDT) and Temperature and Humidity Index (ITU). The results indicate that Teresina has suitable areas for the implementation of urban green corridors, taking advantage of its biophysical base and the structure of the existing road system. The data collected showed significant differences in microclimatic conditions between wooded and non-wooded regions, reinforcing the relevance of vegetation in mitigating the effects of urban heat.
