The forcibly displaced, chronically marginalised, and geographically dispersed Chagos Islanders from the Chagos Archipelago in the Indian Ocean have faced multiple challenges in practicing and transmitting their cultural heritage. Funded by AHRC, the CHAGOS: Cultural Heritage Across Generations project supported Chagossians to share and preserve their cultural heritage. During workshops in Mauritius and the UK in 2017, Chagossian elders shared with the younger generations their knowledge of coconut handicrafts, medicinal plants, cuisine, musical instruments and song and dance. Photographs, instructive films, and artefacts generated at these intergenerational heritage transmission workshops were displayed in exhibitions installed six times in Mauritius, La Réunion, and the UK. The CHAGOS project website displays photographs, instructive films, downloadable recipes, and the Chagos Tambour Group album which was produced by the CHAGOS project in 2018. The CHAGOS team contributed to the Mauritian government’s nomination file for the successful inscription of Chagossian tambour music on the UNESCO List of Intangible Cultural Heritage in Need of Urgent Safeguarding in 2019.
