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

We have scored the climate risk of the 3.057 buildings in Eivissa using Cadastre data, satellite imagery and climate projections, and added it up by area, neighbourhood, street and watercourse. The clearest change comes at night: from 62 to 88 tropical nights a year by 2050.

What stands out

What we found in Eivissa

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

3.300 homes in a flood zone

3.300 homes

They are in the area that can flood once every 500 years according to the official maps (SNCZI); 2.980 of them are in the 100-year area. Next to Torrent des Fornàs, 412 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.

5.611 homes less than 2 m above sea level

5.611 homes

That is 23 % of homes. The extreme sea level in a 100-year storm reaches 1,12 m today and 1,44 m by 2050.

Ground elevation at the building (IGN digital terrain model). Being low-lying does not mean it will flood: that depends on the beach, sea defences and drainage.

From 62 to 88 tropical nights a year

62→88 nights

In a typical building in Eivissa, nights when the temperature stays at or above 20 °C would rise from 62 a year (1991-2020) to about 88 by 2050. For this reason, 100 % of homes would be at a high or very high level.

12 schools in heat islands

12 of 14

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.

In Passeig Maritim, the ground is sinking 1,8 mm a year

−1,8 mm/yr

This is the median of its 59 buildings measured by satellite (Copernicus EGMS, 2020-2024); 22 are sinking 2 mm a year or more. For the municipality as a whole, the median is −1,2 mm/yr.

  • Carrer del Port d'Eivissa
  • Avinguda Santa Eulària des Riu
  • Avinguda de Sant Jordi
  • Avinguda del Vuit d'Agost
  • Carrer de s'Illa Negra

It is not dangerous in itself and we do not know the cause. It is worth keeping an eye on: cracks, and whether the sinking continues.

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 12 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.
  • Monitoring of ground movement in Passeig Maritim: cracks, water mains and buildings.

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.
