What international organization released a report in January 2026 declaring the dawn of an era of global water bankruptcy?

In January 2026, the United Nations University Institute for Water, Environment and Health (UNU-INWEH) released a significant report titled "Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post (Review)-Crisis Era." This report starkly declared that the world has entered an era of "global water bankruptcy," moving beyond the long-warned "water crisis." The distinction is crucial: a crisis implies a temporary shock followed by recovery, while bankruptcy signifies a persistent and often irreversible state where water systems can no longer realistically return to their historical conditions.

The report highlights that many societies have not only overspent their annual renewable water "income" from rivers and soils but have also depleted long-term "savings" stored in vital natural capital such as aquifers, glaciers, and wetlands. This over-withdrawal and pollution have led to irreversible damage, meaning that key parts of the water-related natural environment are damaged beyond realistic prospects of full recovery. For example, more than half of the world's large lakes have lost water since the early 1990s, and approximately 35% of natural wetlands have been lost since 1970.

This dire assessment underscores that billions of people are now living with chronic water insecurity. The report emphasizes that nearly three-quarters of the global population resides in countries classified as water-insecure or critically water-insecure, with about four billion people experiencing severe water scarcity for at least one month each year. The United Nations calls for a fundamental shift from simply reacting to emergencies to implementing "bankruptcy management," which involves honest, science-based adaptation to new hydrological realities, protecting remaining water resources, and ensuring water justice for all.
