CoCE - COnservation and use of wild populations of Coffea arabica in the montane rainforests of Ethiopia


biodiversity, conservation and use, coffee, economic valuation of diversity, rainforest




The aim of the research project is to assess the diversity and the economic value of the Ethiopian coffee gene pool and to develop concepts of model character for conservation and use of the genetic resources of Coffea arabica in its center of diversity in Ethiopia. The concepts are to be based on the conservation of the montane rain forests as the natural habitat of the wild coffee populations, and the forest coffee systems as the traditional use of the wild coffee populations.


The investigation of wild coffee populations in their comprehensive biodiversity context calls for an approach that considers natural sciences, economics and social sciences as well as biological and ecosystem cause-effect chains. An interdisciplinary research approach is chosen to develop conservation and use concepts that are ecologically sustainable, economically efficient and at the same time socially acceptable.
