This paper examines the links between jihadi organizations and illegal criminal activities in the Sahel region. Based on extensive interviews conducted in the region, the paper argues that, while radical organizations are linked with activities such as human trafficking and drug trafficking, this is not their main sources of revenue, which in fact generally comes from kidnapping. Furthermore, the paper shows that those groups have developed links with illegal networks that deal in the basic goods the organizations need, such as gas, weapons and food. While jihadi groups do maintain relations with various illegal economic sectors in the Sahel, those relations are not as strong as many have argued.
