Duma (also known as Aduma, Adouma, Badouma, or Liduma, ISO 639-3: dma) is a Bantu language spoken by approximately 24,000 people in Gabon, primarily along the Ogooué River and its tributaries in the interior of the country. The Duma are a river-faring people, historically known as skilled traders and navigators on the Ogooué. The Coordination Inter-Eglises pour la Traduction et l'Alphabétisation en Langue Gabonaise (CIEATLG) — a church-based organization coordinating Bible translation and literacy across Gabonese languages — produced audio Scripture portions in Duma covering the Gospel of Luke, Acts, Philemon, and Jude. These four New Testament books represent the primary Scripture resource currently available for the Duma community. Gabon has a diverse linguistic landscape with many Bantu languages spoken by relatively small populations, and CIEATLG works to ensure the churches of Gabon have access to God's Word in the vernacular. The Global Recordings Network also provides audio evangelism materials in Duma. The Duma people are superficially reached with Christianity, with many identifying as Christians but in need of deeper engagement with biblical teaching in their mother tongue.
