1- Done. 2- In my city, Porto, UHI is already a phenomenon with considerable expression. In fact, that area some local researches regarding to this subject to understand the origins, patterns and consequences of the UHI. The increase of temperature in high densified areas, in comparison with more rural areas, has variations but in most of the cases it demonstrates a difference of 2 to 4/5 degrees celsius. The referred urban areas with high density have also a high percentage of impermeable areas, that absorve the heat during the day and free during the night, and consequently promotes the increase of traffic that also leads to greenhouse gases emissions leading to the UHI phenomenon. 3- In the previous answer it´s possible to conclude that all mechanisms important to the promotion of UHI are connected and integrated like a system. So, to mitigate this problem we have to think and operate with the same logic, create a network of processes that are connected and function as a whole-system. The strategies would be: decrease the percentage of impermeable areas by creating more green areas associated to public spaces or urban horticulture and mobility infrastructures; promotion of green roofs by including tax benefits; creation of sustainable infrastructures to enable soft mobility and public transportion. 4- Not at the moment.
