In the southern Colombian department of Putumayo, coca cultivation remains one of the few economic options for rural families in this neglected border region. This project follows farmers and families whose livelihoods depend on an illicit economy shaped by poverty, weak state presence, and armed control, as well as members of Comandos de la Frontera, the armed group that controls the territory and the cocaine trade. While some families try legal alternatives, coca often provides the only stable income. Under the Shadow of Coca shows that many of the local producers are not traffickers, but campesinos (farmers), and that it is usually armed groups who profit from the trade of coca.
