I checked like half of the cities. I tried to be as random as posible, from east to west, north of south, cities with coast, mountains, significant rivers or lakes.. The results were quite variable, each city is obviously a unique climate and the UHI effects are very different from each other, a really interesting exercise. **2- Which are the main UHI effects that you can identify in your area?** My city, **Morelia**, in Mexico, have many rural areas in the outskirts, for this example I used **Jesus del Monte**, which is a small town that is getting absorbed by the city, but is still a rural area, with small houses and a lot of wild vegetation. I named them 01 (Morelia) and 02 (Jesus del Monte) for the images. ![Satellite image showing Morelia's urban area and Jesus del Monte in the outskirts][1] ![Panoramic views of Morelia (left) and Jesus del Monte (right)][2] In both the satellite image and the panoramic views, is quite easy to realize how the UHI effect is an issue, in Morelia (01) we can observe a dense area, with around 90% of the area occupied by buildings and only 10% by green spaces. On the other hand we have Jesus del Monte (2) where it can be seen as a mirrored image of Morelia, with around 10% of buildings and 90% vegetation. ![Climate of Morelia][3] ![Climate of Jesus del Monte][4] The table 01 show the historic climate of Morelia, where we can see an annual average max. of 26.9°C, an annual average of 18.7°C and an annual average min. of 10.5°C. The table 02 show the historic climate of Jesus del Monte, where we can see an annual average max. of 24.5°C, an annual average of 17.0°C and an annual average min. of 9.5°C. In conclusion, the urban area is 1.7°C hotter than the rural area, with the annual averages. **3- Which are the measures you would propose?** I think that the easiest and more realistic way to reduce the UHI effect, would be the creation of green areas, spaces that may help the heat breathe and flow. I think other issue that helps the UHI effect are the streets and parking lots, big slabs of concrete and asphalt that are impermeable and don't let the rain water pass through and recharge the aquifers, so a solution like permeable concrete streets and parking lots, with green areas wouldn't be too imposible to accomplish. **4- Is UHI effect concerning policy making in your area?** I've never heard anything regarding the UHI effect in my area, much less a policy or plan to reduce it.
