Water, Climate and World Heritage: Navigating Threat and Opportunity

The frequency and intensity of weather extremes are rising globally due to anthropogenic climate change, the degradation of ecosystems' integrity, and the breach of six out of nine planetary boundaries over the last decades (Richardson et al. 2023). Water is central to understanding these changes and a critical focus for adaptation. According to the World Meteorological Organization (2021; cited in UNESCO 2025a), water-related hazards such as droughts, storms and floods have caused over 90 per cent of the world's major disasters since 1970, and have led to more than 2 million deaths and economic losses exceeding USD 3.6 trillion.
