The Chapra and Kandozi communities number about 3,255 people, living in the Western Amazon Basin in Loreto, Peru. The communities are under threat from epidemic diseases and pollution from oil extraction activities. The two groups speak mutually intelligible varieties of a single language, which is not known to be related to any other linguistic group. This project aims to complement ongoing work on the description of the Kandozi variety, by visiting Chapra communities and collecting linguistic data. In addition to the academic benefits, we hope to help the community document traditional knowledge that is under threat from a changing lifestyle. Primary investigator: Simon Overall
