The Transnational Organized Crime Threat Assessment – Sahel (TOCTA Sahel) consists of a series of research reports that provide in-depth analysis of the main criminal markets in the Sahel, including trafficking in medical products, fuel trafficking, firearms trafficking and the smuggling of migrants. The reports paint a comprehensive picture of the enablers of organized crime and its impact on the region. They do this by highlighting the diversity and multiplicity of criminal flows and actors in the region and by emphasizing the role of corruption in the legal supply chain as a catalyst and/or facilitator of trafficking. They revisit certain assertions, most notably on the nexus between terrorism and organized crime and the type of actors involved in the exploitation and abuse of migrants in transit in the Sahel, and assess how organized crime undermines stability in the region.
