WP 2 - RISK AND VULNERABILITY ASSESSMENT BASED ON CLIMATE SCENARIOS
The developed GIS-based thematic maps provide fine-grained climate data, visualising site-specific risks within the STECCI Maze Figure 1 (Climate Stressors-Mechanisms-Hazards, Biodeterioration, Air Pollution-Impact). Key climate stressors (temperature, precipitation, solar radiation, humidity, wind) and site-specific air pollutants (COx, SOx, NOx, PMx) were identified. STECCI DRFs matrix was developed along the predicted rate of stone deterioration in µm/year for each site. The biodeterioration analysis identified 24 moss and 15 lichen species, classified by their conservation hazard and impact on limestone deterioration.
WP3 CONDITION ASSESSMENT, MONITORING AND CONSERVATION TREATMENTS ON CHOSEN STECCI
WP3 focuses on the long-term preservation of limestone cultural assets in outdoor environments, considering climate change (WP2). On-site landscaping and archaeological work at designated sites in Bosnia & Herzegovina were completed. Condition Assessments (CAs) were conducted at 12 sites in Austria, Germany, France, and Malta, as well as at eight sites in B&H and Croatia. Additional assessments in Montenegro and Serbia are planned for spring 2025. In-situ assessments were conducted using non-destructive methods - visual inspection, decay mapping, water absorption, colour/gloss measurements, ultrasonic pulse velocity, and reflectance transformation imaging. A total of 11 exposure racks were produced, with nine already installed.
WP4 DIGITISATION
Digitisation focused on large-scale digital documentation of Stećci sites using 3D scanning technologies. Aerial photogrammetry and LIDAR captured entire sites, while close-range photogrammetry documented individual stećci. Data acquisition was completed between in 2024 for Hundskirche (AT), Žugića bare (MNE), and Ravanjska Vrata, Radimlja, and Dugo Polje (B&H).
WP5 COMMUNITY-BASED IMPACT STRATEGIES FOR SUSTAINABLE STECCI ECOSYSTEM
Work Package 5 focuses on co-creating a research strategy with researchers, practitioners, and volunteers. The STECCI Social Innovation Labs (SI Labs) framework is developed, producing a comprehensive handbook and establishing labs in B&H, CRO, and MNE. Citizen science pilots were launched in DE and SRB. Co-creation methods were implemented through 17 workshops, including mapping walks.
WP6 ECONOMIC VALUES
WP6 focuses on assessing the economic impact of climate change on stećci and developing strategies for sustainable preservation and cultural tourism. Three models were developed: the Cost-Benefit Analysis (CBA) to evaluate conservation strategies, Contingent Valuation Method (CVM) to measure public willingness to pay for conservation, and the DICE Model to assess long-term economic impacts under different climate scenarios.
