Water supply 'bankruptcy' puts billions at risk, UN report warns
The world is facing an unprecedented water crisis, with billions of people struggling to cope with the consequences of decades of overuse and shrinking water supplies. According to a recent report by the United Nations University Institute for Water, Environment and Health, nearly three-quarters of the global population lives in countries classified as "water insecure" or "critically water insecure."
The report highlights the dire situation, stating that 4 billion people face severe water scarcity for at least one month each year. Kaveh Madani, lead author and director of the institute, emphasizes the critical nature of the issue, saying, "Many regions are living beyond their hydrological means, and many critical water systems are already bankrupt."
The problem is exacerbated by decades of unsustainable extraction rates, which have depleted water "savings" in aquifers, glaciers, soils, wetlands, and river ecosystems. Pollution further degrades water supplies, making the situation even more dire. The report estimates that over 170 million hectares of irrigated cropland are under "high" or "very high" water stress, resulting in economic damages exceeding $300 billion annually worldwide.
The impact is particularly severe in areas with declining water storage levels, where three billion people and over half of global food production are concentrated. Salinization has also degraded more than 100 million hectares of cropland. The researchers argue that the current approach to solving water problems is inadequate, and a new global water agenda is needed to minimize damage.
However, Jonathan Paul, a geoscience professor at Royal Holloway, University of London, points out a critical factor often overlooked. He states, "The elephant in the room, which is mentioned explicitly only once, is the role of massive and uneven population growth in driving so many of the manifestations of water bankruptcy."
This report serves as a stark reminder of the urgent need for action to address the global water crisis and protect the billions of people at risk.
