A team of international scientists, including CABI’s Dr Urs Schaffner, have recommended ways to manage the devastating spread of the woody weed Prosopis juliflora, where in Baringo County, Kenya, its coverage rapidly increased by 2,031 percent in just 28 years.

PhD student Purity Rima Mbaabu, affiliated to the University of Nairobi and co-supervised by Simon Choge, Kenya Forestry Research Institute, Dr Sandra Eckert, Centre for Development and Environment, University of Bern, Switzerland, Profs. Maina Gichaba and Prof. Daniel Olago, University of Nairobi, and Dr Schaffner, is lead author of new research which states that the rates of Prosopis invasion in Kenya are a ‘major threat to the environment and rural people’s livelihoods.’

The study calls for the ‘urgent implementation of coordinated and sustainable Prosopis management in Baringo County and other invaded areas in East Africa’.

Invasive alien species should not be used in restoring degraded landscapes as their costs outweigh their benefits, experts say.
