What stands out

What we found in Tortellà

It comes from matching each building with its neighbourhood, its street, the nearest watercourse and its surroundings.

1

Where there are fewer trees, 4,6 °C hotter

4,6 °C

Around homes with between 2 and 5 % tree cover, the surface in summer is 1,2 °C above the median for Tortellà; with more than 40 % tree cover, 3,4 °C below. 2 homes are in surroundings with almost no trees.

Ground surface temperature (Landsat), not air temperature. More trees usually go with less asphalt and lower density: this is a correlation, not a measure of the effect of planting trees.

2

From 1 to 24 tropical nights a year

1→24 nights

In a typical building in Tortellà, nights when the temperature stays at or above 20 °C would rise from 1 a year (1991-2020) to about 24 by 2050. For this reason, 0 % of homes would be at a high or very high level.

What can be done

For the town council and for residents

For the town council and its technical staff

  • Shade and trees in the playgrounds of the 1 schools with the hottest surroundings.
  • Review with the river basin authority the watercourses with no official mapping that run next to homes, and keep them clear.
  • Firebreaks and evacuation routes in the streets that border woodland.
  • Download the tables by area, neighbourhood, street and watercourse (Data tab) to cross-check them with urban planning.

For residents

  • If you live on a ground floor or have a garage next to a watercourse, have a plan: where to go upstairs, what to switch off and how to hear about warnings.
  • Keep the strip around your house clear of dry vegetation and know both ways out of your street.
  • Look up your building: the free report gives its level for each hazard, and the Climate Note gives the full detail.
