 Migrants as messengers is a unique peer-to-peer communications campaign that uses a participatory design approach to inform migrants about the risks of irregular migration. The campaign's innovative approach put the power of a mobile film studio in the hands of returnees who were trained to interview their peers about their experiences as irregular migrants. The results were a catalog of over 5,000 powerful and highly personal stories from trusted voices that were shared widely across social media, radio, and at dozens of community events in Senegal, Nigeria, and Guinea. The scientific evaluation of the campaign in Senegal found the approach made a significant impact on public attitudes and perceptions about irregular migration among young people.
