On the occasion of Heritage Days, the French newspaper Ouest-France has published the findings of a unique study conducted by the Edhec business school. The study evaluates how exposed the French UNESCO World Heritage sites are to climate-related risks. These sites, recognized for their cultural or natural significance, are now being assessed for their vulnerability to environmental changes such as rising sea levels, extreme weather events, and increased temperatures. The research highlights that several of France’s most iconic heritage sites are at risk due to climate change. For example, coastal sites like the Bay of Somme and the Île de Ré are threatened by rising sea levels and more frequent storms. In contrast, some mountainous or inland sites face risks like prolonged droughts or forest fires, which can damage historical structures and landscapes. The study also underscores the importance of preserving these sites for future generations. Many of these locations are not only of cultural significance but also attract millions of tourists annually, contributing to local economies. The findings call for increased awareness and action to implement protective measures that can safeguard these treasures against the growing impacts of climate change. Edhec’s research adds a new dimension to the conversation around heritage preservation by integrating climate science with cultural heritage management. It serves as a reminder that while these sites are celebrated for their historical and natural value, they are also increasingly vulnerable to the environmental challenges of the 21st century.
