What stands out

What we found in Cortegana

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

1

Where there are fewer trees, 5,6 °C hotter

5,6 °C

Around homes with less than 2 % tree cover, the surface in summer is 4,9 °C above the median for Cortegana; with more than 40 % tree cover, 0,7 °C below. 69 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.

1.233 homes at very high wildfire risk

1.599 buildings

These are 1.599 buildings right next to vegetation that can burn. Of these, 3 are blocks of flats with 69 homes, where evacuation is harder.

  • Calle Matrona María Tamarit: 27
  • Calle Castaño: 22
  • Calle María Zambrano: 20

Proximity to woodland and to burnt areas (ESA WorldCover, EFFIS). It does not measure the state of the vegetation or any firebreaks.

From 2 to 15 tropical nights a year

2→15 nights

In a typical building in Cortegana, nights when the temperature stays at or above 20 °C would rise from 2 a year (1991-2020) to about 15 by 2050. For this reason, 0 % of homes would be at a high or very high level.

3 schools in heat islands

3 of 3

Schools whose surroundings are at least 1 °C hotter than the municipal median in summer. They are the first candidates for shade and tree-lined playgrounds.

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 3 schools with the hottest surroundings.
  • 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

  • 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.
