The Long Dry - Why the world’s water supply is shrinking

Prof Ashish Sharma and UNSW Dean Engineering, Prof Mark Hoffman, summarise the research and call for an international discussion on its implications.

A global study has found a paradox: our water supplies are shrinking at the same time as climate change is generating more intense rain. The study - led by UNSW academics - finds that the culprit is the drying of soils, and points to a world where drought-like conditions will become the new normal, especially in regions that are already dry.
