Across the world, a large part of slope instability phenomena of different type (e.g. landslides, rockfalls, debris flows) is recognized to be regulated by weather patterns largely differing in terms of variables (precipitation, temperature, snow melting) and significant time span (from a few minutes up to several months). On the other hand, local modifications induced by human intervention: e.g. socio-economic induced land use/cover changes, reduced soil management due to land abandonment or implementation and maintenance of Nature Based Solutions are recognized playing a key role in slope instability risk. In turn, such local human-induced factors can be strongly influenced by weather dynamics: e.g. hydrological and thermal regime regulate vegetation suitability, then land cover and, in turn, landslide risk.
A clear and robust evaluation about how ongoing and expected global warming and resulting climate change can affect such factors and, therefore, landslide risk represents a clear need for practitioners, communities, and decision-makers.
The Session aims at presenting studies concerning the analysis of the role of climate-related variables and slope-atmosphere interaction on landslide/rockfall triggering/activity and/or effectiveness of protection measures, across different geographical contexts and scales. Test cases and investigations (by exploiting monitoring and modelling) carried out in different geographical contexts in evaluation of ongoing and future landslide activity are welcome. Furthermore, are greatly welcome investigations focused on data-driven approaches (e.g. Machine Learning, AI) through which the variations induced by climate and environmental changes on triggering, dynamics, and hazard are analysed.
