What stands out

What we found in Ojén

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

1

2.081 homes at very high wildfire risk

1.054 buildings

These are 1.054 buildings right next to vegetation that can burn. Of these, 29 are blocks of flats with 1.508 homes, where evacuation is harder.

  • Calle Miguel de Cervantes: 374
  • Calle Velázquez: 160
  • Calle Victoria Kent: 158

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

2

From 39 to 74 tropical nights a year

39→74 nights

In a typical building in Ojén, nights when the temperature stays at or above 20 °C would rise from 39 a year (1991-2020) to about 74 by 2050. For this reason, 100 % of homes would be at a high or very high level.

Where there are fewer trees, 2,8 °C hotter

2,8 °C

Around homes with between 2 and 5 % tree cover, the surface in summer is 1,3 °C above the median for Ojén; with more than 40 % tree cover, 1,5 °C below. 3 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 schools in heat islands

2 of 2

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 2 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

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