The indicator provides information about the landslide number and distribution in Italy. The recorded landslides exceed 635,000 (reference period 1116-2024) and affect an area of 25,004 km², accounting for 8.3% of the national territory.

The indicator provides information about the major landslide events caused fatalities, injuries, evacuations, damage to buildings, cultural heritage, and primary linear communication infrastructure or service networks in the national territory in the past year. The major landslide events occurred in 2023 were 192, with 11 deaths, 24 injuries, and damage mainly to the road network and buildings.

The monitoring of hydrogeological risk mitigation projects funded from 1999 to December 31, 2023, by various administrations across the national territory is carried out by ISPRA through the ReNDiS platform (the Italian Repository of Hydogeological Mitigation measures). A total of 25,539 projects are recorded in ReNDiS, with a total funding amount of €19,207 million. Of these, the projects under the jurisdiction of the Ministry of the Environment and Energy Security (MASE) account for just over 26% (6,750) of the total, corresponding to approximately 41% (€7,819 million) of the total resources allocated by the other public funding administrations listed in ReNDiS. These include the Ministry of the Interior, the Civil Protection Department, the Casa Italia Department of the Presidency of the Council of Ministers, the Ministry of Agriculture, Food Sovereignty and Forests (MASAF) and the Calabria Region.

Specifically, projects under the jurisdiction of the Ministry of the Interior, the Civil Protection Department, the Casa Italia Department, MASAF and the Calabria Region represent over 73.5% (18,789) of the total number of projects, with funding exceeding 59% (€19,207 million).

Regarding the implementation status of all funded projects, 8,813 (approximately 34%) have been completed, 12% (2,951 projects) are under execution, 19% (4,836 projects) are in the design phase, while nearly 34% (8,703 projects) have yet to be started or have no reported data. The indicator also provides data on the regional distribution of projects and their classification based on the type of hydrogeological failure. Additionally, it presents data on funding requests submitted by Regions/Autonomous Provinces to MASE and the Casa Italia Department for the implementation of new hydrogeological risk mitigation projects, totaling 1,542 requests for a total project funding amount of approximately €4,440 million.
