A new study by GIWS alum Magali Nehemy shows that in the dry season, Amazon trees recycle recent rainfall from shallow soils by rapidly transpiring it back into the atmosphere. This sustains the forest and contributes to “flying rivers” that help maintain rainfall across South America.

Researchers explain how trees in the rainforest efficiently recycle water through rain to keep themselves hydrated in the dry season.

Low water years like this are a reminder of how closely our communities are tied to the ebbs and flows of the river.

Global Institute for Water Security @water.usask.ca · May 13

The good news is that there is enough water in the South Saskatchewan River to support food production and supply safe drinking water. But there isn’t enough flow to shift the buildup of sediment that’s making parts of the river harder to navigate.
