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’.

Riverbank invasion of Prosopsis

CABI scientists have helped map the ferocious speed and probable cause of a devastating spread of the invasive alien tree Prosopis juliflora (Swartz DC) across an area equivalent to half of neighbouring Djibouti in the Afar Region of north eastern Ethiopia.

Dr Urs Schaffner, who is supervising lead author Hailu Shiferaw for his PhD studies, contributed to the Scientific Reports published paper ‘Modelling the current fractional cover of an invasive alien plant and drivers of its invasion in a dryland ecosystem’, which shows that the Prosopis invaded 1.2 million ha of grassland/shrubland in just 35 years.
