UHI Effects [Urban] - Dallas, Texas. ![Dallas, U.S.A - Downtown][1] (i) The summer heat in Dallas is 19 degrees hotter in the city than in nearby rural areas. (ii) The large concrete areas like roads, buildings and infrastructure in the urban area as shown in the figure above, make it much hotter than in rural areas. (iii) By its nature concrete, asphalt and buildings tend to absorb heat and a lack of trees as well as other plant life prevents natural cooling from occurring. UHI Effects [Rural] - Richardson, Texas. ![Richardson,TX, U.S.A][2] (i) One effective tool shown to lower urban temperatures and improve air quality is the planting of trees. Many of the tree covered neighborhoods as shown above, have one of the coolest temperatures compared to the rest of the city. (ii) Large trees can provide shade to block the sun's heat. (iii) Trees have a "moisture emitting" process, otherwise known as evapotranspiration that cools the urban air temperature by releasing moisture, hence decreasing the effect of UHI. 3. Which are the measures you would propose? The measures that I would propose is to spread awareness about planting more trees in urban areas that would lead to reduction in UHI effect. 4. Is UHI effect concerning policy making in your area? The Urban Forest Advisory Committee (UFAC) is helping to reduce the UHI effect, by encouraging various tree planting projects across Dallas – especially in the concrete laden parts of our city. The Adopt-A-Median project, increased planting in city parks and street medians, inclusive of other key tree planting projects and obtaining funding and support for such projects are some of the ways UFAC is helping to restore trees to Dallas urban areas and reducing the heat island effect.
