The article delves into the intricate relationship between climate change and the preservation of cultural heritage, focusing on the archaeological site of Nora in Sardinia. The study underscores the vulnerability of Nora’s building materials to weathering processes exacerbated by climate change, such as increased greenhouse gas concentrations and rising sea levels. To better comprehend the impact of these environmental changes, accelerated decay tests are being conducted to assess the deterioration of lithoid materials at the site.
Moreover, the research sheds light on the significance of protective measures, such as nanolime and nanosilica coatings, as cost-effective solutions to counteract the decay of lime-based stones, plaster, and mortars, as well as siliceous stones. The study also highlights the potential submergence of parts of Nora due to coastal erosion resulting from rising sea levels, with projections indicating coastline shifts and submerged areas under different shared socioeconomic pathway scenarios.
By providing insights into current and projected decay patterns, the study aims to inform stakeholders and authorities about the urgent need for maintenance plans and protective interventions to safeguard Nora’s cultural heritage. Ultimately, the research underscores the importance of proactive strategies and technological advancements in mitigating the adverse effects of climate change on archaeological sites like Nora, emphasising the critical role of climate change risk assessment in preserving cultural heritage for future generations.
