Kerala is home to a rich tapestry of Indigenous Knowledge developed by tribal communities such as the Irula, Kurichiya, Paniya, Muthuvan, and Adiya. This knowledge encompasses traditional medicine, sustainable agriculture, ecological wisdom, rituals, art forms, and oral traditions. Rapid modernization, migration, and environmental changes, however, have put this invaluable knowledge at risk of disappearing. Digital preservation offers a viable solution by documenting, storing, and providing long-term access to oral histories, folk practices, medicinal knowledge, tribal languages, and performance traditions through audio-visual recordings, digital texts, and online repositories. While digital preservation facilitates intergenerational knowledge transfer, academic research, and wider cultural awareness, it also raises challenges such as ethical concerns, ownership rights, potential cultural exploitation, and loss of contextual understanding. This paper explores the significance, methods, merits, and limitations of digitally preserving Indigenous Knowledge in Kerala and emphasizes the need for community-centered, ethical, and sustainable preservation strategies to ensure cultural continuity and empower indigenous communities.
