The Impact of Arborization as an Urban Heat Island Mitigation Strategy in the Colombian Caribbean
Keywords:
Climate change, Heat Island effect, urban tree planting, microclimate, operative temperatureAbstract
The Urban Heat Island (UHI), caused by the increase in impermeable surfaces, high urban density, and lack of shade, is a common phenomenon that could end intensified by climate changes, especially in warm-humid climates. This research evaluated the use of urban arborization as a mitigation strategy for the heat island effect in the public spaces of Barranquilla, Colombia. The "Carrera 44" avenue was selected as the study area due to its high solar radiation exposure. Computational simulations were performed to assess the operative temperature with different options for tree shadow in 2020 and 2050. The results display the percentage of UHI mitigation for each proposed situation. It is estimated that the findings from this study can serve as guidelines for designing public spaces in the Colombian Caribbean region.
