**3. Conclusions**

Landslides are global geomorphological phenomena that occur in all geographic regions in response to many predisposing and triggering factors. Directly and indirectly, they impact territories, causing fatalities and huge socioeconomic losses due to environmental degradation and rapid population growth. Consequently, to support sustainable territorial plannings and operative activities, there is a clear need for valid land-use policies, and best long-term risk mitigation and reduction practices. The contributions to this Special Issue represent valuable scientific advances in geomorphological field activities, satellite remote sensing, landslide susceptibility mapping, and numerical modelling, offering practical support for mapping and monitoring of landslide dynamics at both the local and regional scales. All landslide types have been considered, from DGSDs to complex and historical landslides, from rockfalls to debris flows, and from slow-moving slides to shallow landslides. The results described in each article allow for the definition of mitigation activities needed to manage permanent settlements, recreation infrastructures, buildings, and ski facilities. Each paper provides a scientific and methodological basis used to support the idea that landslide hazard assessments must be accurately defined to help local administrations, decision-makers, and interested stakeholders in land planning, emergency planning, and protecting the environment and human life.
