UN Headquarters, New York (20 January 2026)– Amid chronic groundwater depletion, water overallocation, land and soil degradation, deforestation, and pollution, all compounded by global heating, a UN report today declared the dawn of an era of global water bankruptcy, inviting world leaders to facilitate “honest, science-based adaptation to a new reality.”

“Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post-Crisis Era,” argues that the familiar terms “water stressed” and “water crisis” fail to reflect today’s reality in many places: a post-crisis condition marked by irreversible losses of natural water capital and an inability to bounce back to historic baselines.

“This report tells an uncomfortable truth: many regions are living beyond their hydrological means, and many critical water systems are already bankrupt,” says lead author Kaveh Madani, Director of the UN University’s Institute for Water, Environment and Health (UNU-INWEH), known as ‘The UN’s Think Tank on Water.’

 

Summary

 

Agricultural heartlands are running down their water capital. Roughly
70% of global freshwater withdrawals are used for agriculture. Around 3
billion people and more than half of the world’s food production are located
in areas where total water storage—including surface water, soil moisture,
snow, ice, and groundwater—is already declining or unstable.

More than 170
million hectares of irrigated cropland—roughly the combined land area of
France, Spain, Germany and Italy—are under high or very high water stress.
Land and soil degradation are amplifying water-related risks. More
than half of global agricultural land is now moderately or severely
degraded, reducing soil moisture retention and pushing drylands toward
desertification.

Salinization alone has degraded roughly 82 million hectares
of rainfed cropland and 24 million hectares of irrigated cropland—together
more than 100 million hectares of cropland—eroding yields in some of the
world’s key breadbaskets.

Drought is increasingly anthropogenic and extremely costly. Over 1.8
billion people were living under drought conditions in 2022–2023.

Drought-related damages, intensified by land degradation, groundwater depletion
and climate change rather than rainfall deficits alone, already amount to
about US$307 billion per year worldwide—larger than the annual GDP of
almost three-quarters of UN Member States.

Water quality degradation is shrinking the truly usable resource base. In
many basins, pollution from untreated or inadequately treated wastewater,
agricultural runoff, industrial and mining effluents, and salinization means
that a growing share of water is no longer safe or economically viable for
drinking, food production or ecosystems—even where nominal volumes
have not yet declined dramatically.

The planetary freshwater boundary has been transgressed. Global
evidence shows that two important elements of the freshwater cycle—“blue
water” (surface and groundwater) and “green water” (soil moisture)—
have been pushed beyond a safe operating space, alongside planetary
boundaries for climate, biosphere integrity, and land systems

Existing governance and agendas are no longer fit for purpose. In
many basins, the sum of legal water rights, informal expectations and
development promises far exceeds degraded hydrological carrying capacity
in the absence of effective governance institutions to address water
bankruptcy.

The current global agenda focused primarily on WASH (Water,
Sanitation, and Hygiene), incremental efficiency gains and generic IWRM
(Integrated Water Resources Management) prescriptions is insufficient to
address structural overshoot, irreversibility and the rising risks of social
instability and conflict associated with water bankruptcy.
