The United Nations University released a report on 20 January, based on a peer‑reviewed paper from its Institute for Water, Environment and Health (INWEH). The report defines "water bankruptcy" as persistent over‑withdrawal of surface and groundwater beyond renewable inflows and safe limits, and warns many systems can no longer recover to their historical levels.
It gives several figures: billions lack safe drinking water and nearly half the global population faces severe water scarcity for at least part of the year. Since the early 1990s, water levels have fallen in more than half of the world’s large lakes. Around half of domestic water and over forty per cent of irrigation now come from groundwater, while many major aquifers show long‑term decline.
The report names causes such as long‑term groundwater depletion, land subsidence, loss of storage, weak governance, pollution and rising demand from agriculture and fast‑growing cities. It warns of less reliable water, higher costs, hunger, forced migration and social tension. Recommendations include improving water efficiency, modernising irrigation, drought planning, using treated wastewater and fair finance for affected communities.

Iran faces a severe water shortage made worse by unauthorized groundwater drilling by military-linked actors. Official silence has allowed aquifers to fall, forcing village abandonment and producing wider ecological and social damage.
