The Status of Implementation Research in Exit and Post-Exit Human Trafficking Interventions in Sub-Saharan Africa

Conservative estimates place the number of individuals affected by human trafficking in the sub-Saharan African region at close to nine million. While there has been growing attention paid to innovative prevalence estimation approaches, and development of evidence-based interventions in the region, literature examining how these interventions are adapted, implemented, and delivered across multiple sectors, populations, and geo-political settings remains nascent at best. This critical gap in implementation research stymies the scale-up of effective anti-trafficking approaches. The central aim of this scoping review is to contribute to the anti-trafficking knowledge base by describing the current state of implementation research in this region based on 12 identified peer-reviewed human trafficking studies in sub-Saharan Africa. While none of the retrieved studies focuses solely on the implementation of a human trafficking intervention, the studies identified and discussed the acceptability and cost impacts of their implementation efforts. We conclude that advancing trafficking knowledge and praxis would require the synergistic and concurrent pursuit of both implementation and intervention strategies.
