The international project team will be generating and sharing knowledge on how the invasive species establish and spread and on the effects and impacts of the invaders in the different contexts of Ethiopia, Kenya and Tanzania. They will also be developing and improving measures for controlling the species, which will be built into Sustainable Land Management strategies that will help the countries to mitigate the impacts of the species.
