 Let me ask you a question. Would you change your decision to take a trip if a trusted friend or family member told you about dangers, abuse, exploitation you might face along the way? We know from decades of field work around the world that many migrants leave home with little or inaccurate information about the journey ahead. The consequences of that information gap are obvious and well documented. West African migrants consistently identified other migrants, particularly friends and family members, as trusted sources of information. We needed a way to harness those voices and the result is Migrants as Messengers campaign. 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 so that they can make informed decisions. 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 in a half a dozen languages and dialects 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. Our impact evaluation learned they were better informed about the risks and opportunities of migration and that one in five was less likely to expose themselves to the dangers of irregular migration. The impact evaluation proves that in the fluid context of migration this particular approach which places migrants at the core of peer-to-peer communications actually works and should be replicated in other contexts.
