More trees can boost groundwater recharge

In the African drylands, the predominant view used to be that more trees meant less water soaking into the ground and recharging aquifers. Tree planting was discouraged and in some areas people even uprooted trees.

New research paints a more nuanced picture. It appears that intermediate tree cover can boost groundwater recharge in arid, tropical areas.
