 Growing Water Risks Threaten World’s Most Cherished Heritage Sites
By Samantha Kuzma, World Resources Institute
LONDON, 09 Sept. - (ANA) - Many UNESCO World Heritage Sites are facing severe water risks, threatening ecosystems, livelihoods and the cultural traditions tied to these iconic places.
Water is impacting some of the Earth’s most cherished places: The Taj Mahal, for example, faces water scarcity that is increasing pollution and depleting groundwater, both of which are damaging the mausoleum. In 2022, a massive flood closed down all of Yellowstone National Park and cost over $20 million in infrastructure repairs to reopen.
Water issues — whether it’s drought, scarcity, pollution or flooding — have become a threat to many of the more than 1,200 UNESCO World Heritage Sites. These natural landscapes and cultural landmarks around the globe, including the Taj Mahal and Yellowstone National Park, are recognized for their “outstanding universal value” to people and the planet.
Places ranging from the biodiversity-rich Serengeti National Park in Tanzania, to cultural treasures like the sacred city of Chichén Itzá in Mexico, to bustling urban centers like Morocco’s Medina of Fez are facing growing water risks that are not just endangering the sites, but the millions of people who depend on them for food, livelihoods, a connection to their culture, or who just enjoy traveling to these destinations.
An analysis using WRI’s Aqueduct data shows 73% of all non-marine UNESCO World Heritage Sites are exposed to at least one severe water risk (water stress, drought, river flooding or coastal flooding), with 21% of sites facing dual problems of too much and too little water.
While the global share of World Heritage Sites exposed to high-to-extremely high levels of water stress is projected to rise from 40% to 44% by 2050, impacts will be far more severe in regions like the Middle East and North Africa, parts of South Asia, and northern China — areas where existing water stress is exacerbated by extensive river regulation, damming and upstream water withdrawals. In these regions, the combined pressures of infrastructure development and climate change pose a significant threat to both natural ecosystems and the cultural heritage they sustain. - (ANA) -
