Trees, the best investment against heat in cities
  • On Wednesday, we discussed how the heat reaches the Iberian peninsula during the weekend and how a map application has been developed in the cities to search for the shade. Subsequently, we have found an interesting thread written in Spanish: cities, calores, urban strategies to mitigate the shade and warming; with a protagonist, the planting of trees in the cities.

Here are some images and points recorded by Ruben Carbonero, translated into Basque.

On the one hand, in a city, the most sustainable mobility is that of pedestrians. On a vertical scale we see the image clearly, the worst is the private car. Of course, to facilitate or desire pedestrian mobility, it is important that there are shadows in the city.

And to create the shade, trees give a better method on the streets than buildings do. Soil temperature could be halved on a hot, sunny day.

If the trees are evergreen, better, says Carbonero, because in winter they have an opposite effect.

In general, the presence of many trees causes a good air conditioning effect in a city, while empty asphalt and cement areas are "furnaces" to concentrate the heat. Energy saving studies have also been carried out in the streets with abundant trees in the cities, 30% in middle levels, and in some cases 42%. In addition, it also helps the well-being of people to live surrounded by trees when you are in the city.

City trees also contribute to the prevention of wells that occur when noise, pollution and rainfall occur, so they estimate that the investment in planting and conserving trees is multiplied by 1.5 to 3 times in benefits and savings. Instead of spending, it's a real investment.
