Of the world's large lakes, 50% have lost water since the early 1990s, according to the report. A quarter of humanity directly depends on those lakes, the researchers said.

In addition, 50% of global domestic water is now derived from groundwater, and 40% of irrigation water is drawn from aquifers being steadily drained. Of the world's major aquifers, 70% are showing long-term decline.
