MonzónClimate risk in its neighbourhoods, streets and rivers, today and in 2050

We have scored the climate risk of the 4.688 buildings in Monzón using Cadastre data, satellite imagery and climate projections, and added it up by area, street and watercourse. The clearest change comes at night: from 5 to 35 tropical nights a year by 2050.

What stands out

What we found in Monzón

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

1.608 homes in a flood zone

1.608 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 787 of them are in the 100-year area. Next to Río Sosa, 1.135 homes are inside the flood zone, less than 100 m from the watercourse.

According to the Ministry’s studies, this is an annual probability of 0,2 % (500 years) or 1 % (100 years), not “once every 500 years”: it can happen two years in a row. Small gullies are not always mapped.

From 5 to 35 tropical nights a year

5→35 nights

In a typical building in Monzón, nights when the temperature stays at or above 20 °C would rise from 5 a year (1991-2020) to about 35 by 2050. For this reason, 0 % of homes would be at a high or very high level.

550 homes at very high wildfire risk

1.012 buildings

These are 1.012 buildings right next to vegetation that can burn. Of these, 2 are blocks of flats with 61 homes, where evacuation is harder.

  • Pantano de el Grado: 40
  • Calle Del Molino: 21

Where there are fewer trees, 2,9 °C hotter

2,9 °C

Around homes with less than 2 % tree cover, the surface in summer is 1,4 °C above the median for Monzón; with more than 40 % tree cover, 1,5 °C below. 168 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.

3 schools, care homes or health centres in a flood zone

3 facilities

They are in the official 500-year flood zone or in a preferential flow zone. They are the first to review in an emergency plan: who is inside, how to get out and whether they use the ground floor.

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.
  • 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.
  • Emergency self-protection plans in the schools, care homes and health centres that are in a flood zone.

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.
