According to a major new report from the United Nations University, global water systems are no longer in crisis, but have entered a state of chronic failure, with shortages that extend far beyond temporary shocks or short-term recovery.

Released on January 20 by the UN University’s Institute for Water, Environment and Health (UNU-INWEH), Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post-Crisis Era concludes that the planet has entered the era of global water bankruptcy. This indicates that long-term water use now exceeds renewable inflows, leaving much of Earth’s natural systems damaged beyond realistic repair. In other words, societies have already exhausted or polluted the natural buffers—rivers, aquifers, wetlands, and glaciers—that once sustained them. Droughts, shortages, and pollution events are increasingly becoming persistent features of daily life. In this post-crisis condition, the authors argue, it is best not to describe the situation as a crisis at all, but as water bankruptcy.

At the press conference set to release the report, Kaveh Madani, lead author and director of the UNU-INWEH, emphasized that this is not a semantic shift, but a clear warning that the dominant way governments, markets, and international institutions think about water is no longer fit for reality.

“For decades, scientists, the media, and policymakers have warned about a global water crisis… what we document in this report is a different reality emerging in many places: a persistent failure state in which water systems can no longer realistically return to their historical baselines,” Madani said.

Applied to water, bankruptcy management requires confronting overuse, acknowledging irreversible losses, and aligning development goals with hydrological limits.

The report does not claim that the entire planet is bankrupt. Water bankruptcy is assessed basin by basin and aquifer by aquifer. However, as regions across the globe simultaneously overdraw water and erode the natural systems that sustain it, the world faces a fundamentally altered risk landscape, with cascading threats to food security, agricultural markets, rural livelihoods, and climate feedbacks.

What distinguishes water bankruptcy from familiar narratives of scarcity is the scale of irreversibility. According to the report, societies have not only overdrawn annual renewable water flows, but have also liquidated long-term savings stored in groundwater, wetlands, glaciers, soils, and river ecosystems.

Over the past five decades, the world has lost approximately 410 million hectares of natural wetlands—almost the land area of the European Union—resulting in the disappearance of vital ecosystem services such as flood control, water purification, and habitat provision, valued at more than US$5 trillion. Groundwater depletion is even more consequential. According to the analysis, around 70% of the world’s major aquifers show long-term declining trends. Excessive pumping has already caused land subsidence across nearly 5% of the global land area, including dense urban zones that are home to close to 2 billion people. In some regions, land is sinking by up to 25 centimeters per year, permanently reducing storage capacity and increasing flood risk. These damages are not easily undone. Compacted aquifers, subsided deltas, dried-up lakes, and extinct species represent long-term, irretrievable losses.

As Kaveh Madani emphasizes, “This is not another warning about a future we might still avoid everywhere… It is a diagnosis of a world where, in many basins, the old normal is already gone.”

The current human cost and future risks of water bankruptcy are also staggering. According to the report, nearly three-quarters of the world’s population lives in countries classified as water insecure or critically water insecure. About 2.2 billion people still lack safely managed drinking water, 3.5 billion lack safely managed sanitation, and roughly 4 billion experience severe water scarcity for at least one month each year. The risks are compounded given more than half of global food output is located in regions where total water storage (including surface water, soil moisture, snow, ice, and groundwater) is already declining or unstable.

The report’s crux is that the global water agenda remains stuck in a crisis-response mindset........
