2.the city I live has a high medium temperature, with strong solar radiation levels, that contributes to increase UHI effects. According to studies developed by the Federal University of Piauí, the core avenue in the central district presents temperature around 4.2ºC above those measured in greener places in the fringes of the urban area. The temperature measured at Frei Serafim Avenue was 42,2ºC, while in the local hinterland at the same time was registered 36,2ºC. The picture submitted provides a view of the urban area from the hinterland perspective. 3. Improve urban vegetation is fundamental to create a more livable space in a tropical city. Artificial shelters in specific cases are also interesting solutions to provide more shadow and minimise the effects of radiation. As a growing city, it is also important to discuss guidelines for new urbanisation, considering also wind and solar radiation. Create better public spaces, improve public transportation and sustainable mobility reduce the need for private vehicles, and can have a positive impact on reducing greenhouse gas emissions. 4. Recently, with temperatures increasing highly above the human comfort thermal zone, the municipality is elaborating its urban vegetation masterplan. The main objectives is improve the quality of public spaces and minimise the effects of urban heat islands.
