Abstract
This paper examines continuity and changes in the socio-cultural significance of rivers and streams among the Adi tribe of Arunachal Pradesh, with particular attention to the impacts of modern fishing technologies and market-driven resource extraction. Drawing on qualitative ethnographic data from five villages in Siang District, the study explores Indigenous Knowledge Systems governing rivers and stream ownership, boundary demarcation, ritual significance, and community-based fishing practices. The findings reveal that while traditional practices such as Kegung, Nguok Oknam, and Sibok Pattnam continue to embody principles of ecological restraint, sustainability, and collective action, these systems are increasingly undermined by modern fishing methods, including blast fishing, electrofishing, and river-leasing arrangements. These processes have contributed to ecological degradation, declining fish stocks, and reconfigured cultural meaning attached to rivers and streams. Situating the analysis within the frameworks of Indigenous Knowledge Systems and practice theory, the paper argues that rivers and streams among the Adi are being transformed from culturally embedded commons into contested and commodified spaces, with profound implications for cultural continuity, food security, and social cohesion.
