New Delhi, July 3 -- A new analysis 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 - having too much water one year, and too little during another. The analysis based on World Resources Institute's Aqueduct data (also a water risk atlas) has flagged that several sites in India are among those experiencing severe risks, including the Taj Mahal, Kaziranga National Park, Western Ghats, Group of Monuments at Mahabalipuram, and the Great Living Chola Temples among others. Around 40% of the UNESCO sites are facing issues related to water stress and drought risk while 33% and 4% respectively face challenges from riverine flood risk and coastal flood risk. "Sites at risk include global icons such as the Taj Mahal, Angkor, Yellowstone National Park, Mosi-oa-Tunya / Victoria Falls, the Sagarmatha National Park (Mt Everest) and many more. With water stress projected to intensify in many regions, the implications for ecosystems, cultural heritage, and local economies are significant - but solutions are within reach," the analysis said. For example, WRI's mapping shows Sun Temple in Konark; victorian gothic and art deco ensembles in Mumbai; churches and convents of Goa; Western Ghats etc in India are at extremely high risk of riverine flooding. Drought risk is high for Qutub Minar in New Delhi; Keoladeo national park; Rani ki Vaw stepwell in Gujarat; even Chola temples in Mahabalipuram. "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," the analysis states. 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, it adds. WRI water experts have recommended that local authorities restore vital landscapes that support healthy, stable water, invest in nature-based solutions like planting trees to restore headwater forests or revitalizing wetlands to capture flood waters and recharge aquifers. Such approaches can build resilience to extreme weather and address multiple water challenges simultaneously. Nationally, countries can enact conservation policies to protect vital landscapes from unsustainable development....
