Missionaries using secret audio devices to evangelise Brazil’s isolated peoples

Exclusive: Solar-powered units reciting biblical passages have appeared in the Javari valley, despite strict laws protecting Indigenous groups

Missionary groups are using audio devices in protected territories of the rainforest to attract and evangelise isolated or recently contacted Indigenous people in the Amazon. A joint investigation by the Guardian and Brazilian newspaper O Globo reveals that solar-powered devices reciting biblical messages in Portuguese and Spanish have appeared among members of the Korubo people in the Javari valley, near the Brazil-Peru border.

Drones have also been spotted by Brazilian state agents in charge of protecting the areas. The gadgets have raised concerns about illegal missionary activities, despite strict government measures designed to safeguard isolated Indigenous groups.
