Chile faces water bankruptcy as rivers run low

Chile is confronting a structural water shortage described as "water bankruptcy," where water use exceeds natural replenishment from rainfall, snow, and natural recharge. The concept, presented by the United Nations Institute for Water, Environment and Health, highlights that the country has been in a megadrought for over a decade, reducing river flows, depleting reserves, and increasing reliance on vulnerable water sources. Rural communities increasingly depend on water‑truck deliveries, and even the main basin feeding Santiago, the Maipo River, has been declared a water‑scarcity zone. Experts argue that the crisis is no longer a temporary drought but a permanent imbalance requiring diversified supplies such as safe reuse and desalination, greater efficiency, and protection of ecosystems.

The analysis stresses that the key challenge is to manage water within the limits of the territory, moving beyond waiting for rainy years to implementing lasting policies that address the over‑extraction of aquifers, glaciers, wetlands and lakes.
