1. Check the temperature differences in US cities Undoubtedly the differences in temperature between areas with high urbanization density and rural or semi-rural areas are very evident. 2. Which are the main UHI effects that you can identify in your area? The city of Oaxaca is located to the southeast of Mexico, has a semicalido climate. The city was founded in the middle of a great valley surrounded by great mountains, but the population growth has caused that the slopes are invaded by informal houses, which has had as consequence an important effect of deforestation. Therefore, when urban growth and deforestation are added, temperatures in the city have been higher, because if the wooded area is reduced and the built-up areas are increased, an immediate increase in temperature is caused, which Is very noticeable in the city, which has grown without adequate urban planning, therefore the green areas are very few and the woodland inside the streets is very little. The temperature variation between the central area of the city and the periphery can have a difference of +/- 5 ° C or more. 3. Which are the measures you would propose? In order to have better livability conditions it is necessary to increase the green areas, improve the urban transport system to discourage the use of the vehicle, and thus reduce the emission of polluting gases, retake the bioclimatic design in order to reduce the energy demands to the interior of Constructions, as well as to use materials more friendly to the environment. The climatic comfort not only can work inside the constructions but also at the urban level, with a suitable selection of pavements, a suitable tree in combination with other elements that can make of the cities more habitable spaces. 4. Is UHI effect concerning policy making in your area? In Oaxaca, little work has been done on this, however in 2013 the Law of Climate Change of the State of Oaxaca was issued, although the actions are very few, therefore no results are yet seen. Some proposals are being made for the improvement of public transport and the use of bicycles through the construction of bicycle lanes.
