Peer-to-peer learning can be very effective in sharing knowledge and experience, and encouraging the adoption of new practices and technologies among farmers including youth. FAO training approaches, like the Junior Farmer Field and Life Schools (JFFLS), encourage youth facilitators to share their knowledge in the respective communities, mobilizing and sensitizing their peers regarding agriculture and agripreneurship. On average, it has been estimated that each JFFLS graduate has re-trained 20 other rural youth in his/her district, with a significant spillover effect (FAO, IFAD and WFP, 2015). This brief presents the youth-to-youth mentorship experience promoted by the Youth Inspiring Youth in Agriculture (YIYA) Initiative in Uganda in 2017. Based on actual mentorship experiences, it proposes eight youth-to-youth mentorship models, and provides recommendations on how to harness the full potential of youth-to-youth mentorship in youth agripreneurship development initiatives.
