On November 11-13, 2019 Sara Pacchiarotti participated in the interdisciplinary conference “More than just words: A celebration of southern African languages on the occasion of the UNESCO Year of the Indigenous Languages” organized by Dr. Anne-Maria Fehn in close collaborations with African partners (San Research Center at the University of Botswana) and hosted at the CIBIO-InBIO lab in Vairão (Portugal). The conference brought together people from linguistics, cultural anthropology and the biological sciences, including speakers of Khoisan languages and Bantu languages from Botswana, Namibia and Angola, in order to highlight the importance of indigenous languages and indigenous knowledge in research and biodiversity conservation. Sara Pacchiarotti presented a talk in co-authorship with Koen Bostoen titled “Contact between non-Bantu speaking autochthonous hunter-gatherers and Bantu speakers in Central Africa: New linguistic insights from the BantuFirst Project”.
