New research by Amazon Underworld indicates that at least 67% of a total of 987 Amazon municipalities in six main countries (Bolivia, Brazil, Colombia, Ecuador, Peru and Venezuela) face the presence of criminal networks and armed groups. No presence or information was found in the remainder.

Of these, 32% faced more than one group in their territories, and seven criminal or armed groups operate between two and four different countries covered in this study.

In this document, we present an overview of organized crime and armed groups operating throughout the Amazon Basin, analyzed by local administrative divisions (municipalities, districts, cantons, etc.). The research was conducted in 2025 and the data for the cartography was collected via interviews with primary sources in the territory, researched documents from state agencies and filed petitions for information
