A well-trained and actively involved Community of Practice (CoP) is key to successfully implementing a participatory Research project. Because of this, the UNESCO Chair on Community Radio for Agricultural Education, in partnership with the Office of Research, Extension, and Linkages, rolled out a capacity-building workshop on 6th September 2021. The training targets the CoP for a “Voicing Change: Co-Creating Knowledge and Capacity for Sustainable Food Systems” project. “Voicing Change” received a grant from the Social Sciences and Humanities Research Council of Canada. The project aims to promote more sustainable food systems in Migori (Kenya), North West Territories (Canada), and Southern Brazil. The implementing partners are the UNESCO Chair (Rongo University), the Laurier Centre for Sustainable Food Systems (Canada), and Embrappa Floresta (Brazil). The training focused on the use of Participatory Action Research methodology in studies about sustainable food systems. Policymakers, extension officers, agricultural researchers, food systems experts, and community radio content developers are taking part in the inaugural training, which ends on Wednesday, 8th September 2021.
