Abstract text The risk to cultural and natural and heritage (CNH) as a consequence of natural hazards and impact of climate change is globally recognized. The assessment and monitoring of these effects impose new and continuously changing conservation activities and urgently needs for innovative preservation and safeguarding approach, particularly during extreme climate conditions.
The present contribution aims at illustrating the “Risk mapping tool for cultural heritage protection” specifically dedicated to the safeguarding of CNH exposed to extreme climate changes, developed within the Interreg Central Europe STRENCH (2020 - 2022), which development is strongly based on a user-driven approach and the multidisciplinary collaboration among the scientific community, public authorities and the private sector (https://www.protecht2save-wgt.eu/).
The “risk mapping tool” provides hazard maps in Europe and in the Mediterranean Basin where CNH is exposed to heavy rain, flooding and prolonged drought. Risk level is assessed by the elaboration of extreme changes of precipitation and temperature performed using climate extreme indices defined by the Expert Team on Climate Change Detection Indices (ETCCDI) and by integrating data from:
1) Copernicus C3S ERA5 Land products (~9 km resolution, from 1981 at monthly/seasonal/yearly time scale).
2) Copernicus C3S ERA5 products (~31 km – 0.25° resolution, from 1981 at seasonal time scale).
3) NASA GPM IMERG products (10 Km resolution, from 2000 at seasonal time scale).
4) Regional Climate Models from the Euro-CORDEX experiment under two different scenarios (RCP4.5 and RCP8.5) (12 Km resolution, 2021–2050 and 2071-2100).
5) State-of-the-art observational dataset E-OBS (25 Km resolution, 1951-2016).

The tool allows users to rank the vulnerability at local scale of the heritage categories under investigation taking into account 3 main requirements: susceptibility, exposure and resilience. The functionalities of the “risk mapping tool” are currently under testing at European case studies representative of cultural landscape, ruined hamlets and historic gardens and parks.
The application of Copernicus C3S, Earth Observation-based and products and their integration with climate projections from regional climate models constitutes a notable innovation that will deliver a direct impact to the management of CNH, with high potentiality to be scalable to new sectors under threat by climate change.
By the achievement of the planned objectives, STRENCH is expected to proactively target the needs and requirements of stakeholders and policymakers responsible for disaster mitigation and safeguarding of CNH assets and to foster the active involvement of citizens and local communities in the decision-making process.
