Global Study Finds Forest Loss Makes Watersheds ‘Leakier’ Threatening Long-Term Water Security
A sweeping international study led by researchers at the University of British Columbia suggests that deforestation does more than shrink tree cover it fundamentally alters how watersheds store and release water, potentially undermining long-term water security.
The research, published in the Proceedings of the National Academy of Sciences (PNAS), analyzed hydrological data from 657 watersheds across six continents. The findings show that forest loss along with changes in how forests are spatially arranged increases the proportion of “young water” flowing out of watersheds.
Forest Loss Speeds Up Water Movement
“Young water” refers to rain and snowmelt that moves through a watershed within roughly two to three months of falling. A higher proportion of young wate...
