Climate scenarios indicate increased and more intensive volumes of precipitation, which is probably contributing to an increased propensity for landslides in large parts of the country.

Increased precipitation has a detrimental impact on soil stability and increases the risk of landslides. This is because an increased water pressure in the soil's pores reduces its strength. Increased precipitation may also lead to increased runoff and erosion that affects the stability of slopes. Intense rainfall and saturated soil layers also increase the likelihood of landslides in moraines and mudslides.

Sensitive landslide areas

It is mainly in the country's western and southern parts, as well as areas along the east coast, where the risk of landslides increases in the event of climate change. The risk of ravines developing might increase in parts of Svealand, western Götaland and parts of central and northern Norrland. It is also expected that there will be an increased risk of moraine landslides and mudslides in southern Norrland and northern Svealand.

In order to reduce vulnerability, the physical planning and design of infrastructure and buildings should be take into account the increased risk of landslides.
