This document introduces OER Africa and AgShare, an initiative that promotes open educational resources (OER) in Africa. It discusses that OER has the potential to increase access to high-quality materials, reduce costs, and facilitate collaboration. AgShare specifically focuses on agricultural resources and uses a participatory action research approach involving students and stakeholders to co-create OER. Resources are hosted on the OER Africa website and focus on key agricultural institutions and value chains in several African countries. The next phase will strengthen critical value chains and involve dissemination of the AgShare methodology.
