“…For example, for the rst two decades of the 21st century, in high-income countries in Europe and North America, an increase in urban and peri-urban vegetation is reported, while vegetation cover trends in urban and peri-urban areas are negative in cities in Africa, South America, and Asia [76]. Several local studies also con rm this trend [30], [94]; for example, in 289 cities in China, positive relationships between GDP per capita and urban green areas are reported, these relationships are targeted according to the economic development of each sub-region [30].…”

“…However, the search for new indicators that overcome the GDP's limitations with respect to the relevance of social capital and sustainability of cities remains a challenge in the eld of urban planning in the 21st century [78], [79]. In this sense, eco-systemic services, their classi cation, valuation, and variations due to land-use transitions could be the keys to generating economic indicators closer to sustainability challenges [94], [95].…”

“…These events suggest that urban growth will continue to be more expansive than compact in the next decade [23]. At the turn of the 21st century global urban land expansion rates were shown to be higher than or equal to urban population growth rates [25]. Furthermore, demographics, economics [23], topography [12], land use [5], [26], [27], and other factors, such as politics and the informal economy, were expected to be drivers of city expansion [23].…”

Urban expansion and contemporary climate variations are caused by different proximate and underlying multidimensional factors. A spatiotemporal analysis of the urban socio-ecosystem generates key information for planning a sustainable urban model. We analyzed the spatiotemporal pattern of urban expansion and maximum temperature variations in a hierarchy of four categories of cities in the South American tropics in a sequence of seven-time intervals between 1985 and 2018. We defined the boundaries of 31 cities using spatiotemporal information on climatic, topographic, forest, demographic, and economic dimensions. This information was used to run several linear and nonlinear models that would explain the pattern of urban expansion and maximum temperature variations. We found that the historical pattern of expansion varied over time by city category; however, by the end of the first two decades of the 21st century, expansion was significantly higher for all categories. All dimensions contributed to explaining the expansion. An increasing altitude, the steepness of the slope, and a lower roughness index were the proximate causes of increasing the probability of city expansion; on the contrary, vegetation cover had the least importance, suggesting degradation of peripheral ecosystems. Underlying causes, an increase in the gross domestic product (GDP), and demographic variations were of high importance in explaining the probability of expansion in the region. We suggest that the systematic transition from peri-urban soil to impervious cover in the South American tropics is key to both local and global land surface energy balance.

“…The relationship between the presence and quantity of green areas and air quality improvement was established previously, even for tropical areas (ARROYAVE-MAYA et al, 2019;BONILLA-BEDOYA et al, 2021;JIM;CHEN, 2008;REYNOLDS et al, 2017;RIBEIRO et al, 2021;VAILSHERY;JAGANMOHAN;NAGENDRA, 2013).…”

“…Lastly, the slightly higher effect of supply for CO during periods of more demand, could be due to its low deposition rate (0.002 m s -1 ), which probably increased a little when there were more concentrations of the pollutant in the air. Other modelling studies also found relationships between the decline of PM, CO, NO2 and the increase of greenspaces (BONILLA-BEDOYA et al, 2021;PUGH et al, 2012;ZOU et al, 2016).…”

Epígrafe"A natureza introduziu grande variedade na paisagem, mas o homem demonstrou paixão por simplificá-la. Assim, ele desfaz os freios e contrapesos embutidos pelos quais a natureza mantém as espécies dentro de limites ." Rachel Carson " O medo é uma resposta de sobrevivência. O medo nos faz correr, nos faz pular, pode nos fazer agir sobrehumanos. Mas precisamos de um lugar para onde correr. Sem isso, o medo é apenas paralisante. Então, o verdadeiro truque, a única esperança, realmente, é permitir que o terror de um futuro inviável seja equilibrado e apaziguado pela perspectiva de construir algo muito melhor do que muitos de nós ousamos esperar."
