Climate change is a global reality, leading to consequences for both the natural and urban environment. These changes and their implications can be perceived in features such as ecological cycles, in the economic status of a country, or on the well-being and physical integrity of a population. Hence, this study aimed to analyse the effects of climate change on urban thermal comfort and the physiological limits of a population in a tropical city, applying the Physiological Equivalent Temperature (PET) index and correlating it to the local wet-bulb temperature. The method adopted consists of four stages: (1) assembling weather files for future scenarios; (2) setting up scenarios for computational simulations; (3) choosing the most adequate urban thermal comfort index; and (4) selecting a risk parameter to evaluate human health risk. The results show that the presumed urban temperatures, considering 2050 and 2080 scenarios as parameters, can cause serious damage to inhabitants’ health, given the frequency of high temperatures recorded in some months of the year. Accordingly, it is clear that there is a need for balance between the temperature variables and relative air humidity is required, striving for better comfort conditions, as well as improving users' permanence in external environments.
American countries is characterized by its social and economic fragility. It is impossible to ignore the difficult situation of these cities in the assessment of sustainability. Part of a master's study, this article aimed to suitability analyze of the urban sustainability indicators of the Emerging and Sustainable Cities Initiative of the Inter-American Development Bank to evaluate green and recreational areas, in the face of socioeconomic diversity and intra-urban socio-spatial imbalances, through a comparative study of two regions in Vitória, Brazil. Therefore, it was suggested that regions lacking green areas and recreation coincide with low socioeconomic levels. Here, it is concluded that the heterogeneity of the region should be considered in the analysis of sustainability, reinforcing the complementation by opinion research with the residents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
