El TanqueClimate risk in its neighbourhoods, streets and rivers, today and in 2050

We have scored the climate risk of the 1.416 buildings in El Tanque using Cadastre data, satellite imagery and climate projections, and added it up by area, street and watercourse. The clearest change comes at night: from 31 to 57 tropical nights a year by 2050.

What stands out

What we found in El Tanque

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

1

Where there are fewer trees, 5,0 °C hotter

5,0 °C

Around homes with between 5 and 10 % tree cover, the surface in summer is 3,9 °C above the median for El Tanque; with more than 40 % tree cover, 1,1 °C below. 0 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

1.027 homes at very high wildfire risk

1.062 buildings

These are 1.062 buildings right next to vegetation that can burn. Of these, one is a block of flats with 80 homes, where evacuation is harder.

  • Calle Granero: 80

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

3

From 31 to 57 tropical nights a year

31→57 nights

In a typical building in El Tanque, nights when the temperature stays at or above 20 °C would rise from 31 a year (1991-2020) to about 57 by 2050. For this reason, 62 % of homes would be at a high or very high level.

53 in every 100 buildings were built before 1980

53 %

They were built before the first thermal insulation standard (1979). With 57 tropical nights a year by 2050, they will hold the most heat at night and have the most to gain from a retrofit.

3 schools in heat islands

3 of 4

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

  • Climate shelters, and late-afternoon and evening opening hours at libraries and community centres in the areas with the most tropical nights.
  • 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

  • Air your home in the early hours, shade west-facing walls from the sun and ask about grants to insulate the roof.
  • 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.
