Urban growth and heat islands: A case study in micro-territories for urban sustainability

Rapid urbanization contributes to the development of phenomena such as climate variability, especially in tropical countries, which negatively impact ecosystems and humans, factors that influence urban sustainability. Additionally, increase building construction prevents flow wind streams contributing retention pollutants hot air masses, causing events heat islands (UHI). This study aimed analyze from micro-territorial level, growth on UHI phenomenon over last two decades (2000–2020) locality Kennedy, Bogotá, Colombia. For this purpose, environmental socio-economic were evaluated. former, Landsat satellite images spectral indices used evaluate spatial–temporal variation quantity quality vegetation, bodies water, urbanized areas, impervious surfaces, well calculate land surface temperature its distribution area. With regard factors, variables considered for analysis population density energy consumption. Lastly, a principal component was carried out identify possible associations between contribution each micro-territory The spatio-temporal variations reveal growing trend time, impermeable areas where several economic activities, vehicular traffic, converge, require certain actions be prioritized territorial planning addition public green spaces zones.
