The project addresses the evaluation of the economic value of ecosystem services (ES) in UNESCO-MAB sites from a regional perspective (Africa) and focuses on sites from 4 countries: Benin, Ethiopia, Tanzania, Uganda. The expected results will contribute to the transition to green economy in Africa. This project lasts 30 months (2017-2019) and is financed in the framework of a Memorandum of Understanding between Belspo (Belgian Science Policy) and UNESCO to support research activities in Biosphere Reserves (BR).
