A policy brief about the impacts of alien tree invasion in South Africa
The project used freely available satellite imagery and machine learning to map invasive alien trees within catchments that intersect with surface water strategic water source areas (areas which cover 8% of South Africa’s surface but supply 50% of runoff). Water-related impacts were estimated using freely available remote sensing products and an ensemble evapotranspiration model, validated using 14 flux tower stations nationwide.
The development of this policy brief was funded by the Water Research Commission (WRC) of South Africa under Project C2022/2023-00901: Mapping Woody invasive Alien Plant Species.
