Résumé

The H2020 PHUSICOS project aims at providing new insights into the effectiveness of Nature-based solutions (NBSs) against natural hazards in the context of climate change. One of the demonstration sites is the mountain region of Pyrenees located in the municipality of Laruns (French). The site consists of a very steep slope prone to rockfalls (on average higher than 40°), which overlooks the D934 road that gives access to the Portalet pass in Spain. The average daily traffic ranges between 1500 ‐ 2500 vehicles/day to more than 3000 vehicles/day during summer and winter weekends. The road is highly exposed to rockfall that has caused a fatality and large damages over the last years. Here, we aimed to quantify the benefits of NBSs (forest & protection systems) on the mitigation of rockfall hazard at road level.
