Climate change and human activity are placing serious pressure on coastal and underwater heritage. UNESCO says preparation for managing these pressures remains limited. Rising seas, extreme weather and environmental change can threaten heritage sites. Inventories, documentation and maps help professionals record sites affected by climate change. This evidence can support decisions about safeguarding and adaptation.
In June 2025, UNESCO organized an international conference in Paris with the French partner Drassm. About twenty experts joined four sessions on threats, records, adaptation and emergency response. The event invited officials, researchers, heritage professionals, archaeologists, NGOs and the public. Its goal was to raise awareness and share useful practices and innovative protection strategies. UNESCO also encouraged dialogue between experts and decision-makers. Cooperation across sectors and countries can strengthen protection when climate risks cross professional and national boundaries.
