The United Nations University Institute for Water, Environment and Health (UNU-INWEH) says the world has entered a Global Water Bankruptcy era.
Water Bankruptcy means humans are using more water than can be safely replenished, causing long-term damage to rivers, lakes, aquifers, wetlands, soils, and glaciers.
This is different from water stress (high demand, mostly reversible) and water crisis (temporary shock, fixable with emergency measures).
Causes include slow depletion of water, infrastructure-driven overshoot like big dams, ecological liquidation of wetlands and forests, and climate-amplified overshoot.
The report warns that many water systems may be irreversibly damaged, affecting ecosystems, food security, and livelihoods.
