According to this Spanish language article, 8 of the 22 protected areas in Bolivia have been penetrated by drug trafficking. “Clandestine landing strips, mega-laboratories for the production of cocaine, illegal coca leaf plantations and plane overflights are proof that mafias operate in these areas. The Government announced that the goal is to eradicate 9,000 hectares of coca crops in these reserves and for that purpose operations and intelligence work will be carried out.” Illegal coca leaf plantations are also on the rise. “The most worrying cases are Madidi, in the north of La Paz, and the Isiboro Sécure National Park Indigenous Territory (Tipnis), which is located in Cochabamba and Beni."
In addition, “the United Nations Office on Drugs and Crime (Unodc) counted six protected areas with illegal coca plantations in the past administration . The Madidi case was the most worrying: there was a 171% increase in illegal plantations in this reserve compared to 2018.”
