Natural Processes in the Degradation of Open-Air Rock-Art Sites: An urgency intervention scale to inform conservation: The case of the Côa Valley world heritage site, Portugal

Open-air rock-art sites, though widespread and culturally significant, face severe degradation due to natural processes. A study focusing on the UNESCO World Heritage Site of the Côa Valley in Portugal introduces an urgency intervention scale to assess and prioritize conservation efforts. By analyzing case studies from Norway, Brazil, Southern USA, and South Korea, researchers identify key factors contributing to rock-art decay and propose methods for evaluating current conditions. This approach aims to inform targeted conservation strategies, ensuring the preservation of these vulnerable heritage sites.
