What stands out

What we found in Olivella

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

1

From 15 to 63 tropical nights a year

15→63 nights

In a typical building in Olivella, nights when the temperature stays at or above 20 °C would rise from 15 a year (1991-2020) to about 63 by 2050. For this reason, 100 % of homes would be at a high or very high level.

1.878 homes at very high wildfire risk

1.842 buildings

These are 1.842 buildings right next to vegetation that can burn. Of these, 2 are blocks of flats with 69 homes, where evacuation is harder.

  • Carrer de la Garona: 41
  • Avinguda del Mas Mestre: 28

Where there are fewer trees, 2,5 °C hotter

2,5 °C

Around homes with between 10 and 20 % tree cover, the surface in summer is 2,0 °C above the median for Olivella; with more than 40 % tree cover, 0,5 °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.

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 1 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.
