Globalisation, modernisation and communication technology have resulted into a homogenised global culture. The socio-cultural and economic practises of the Tripuris or Kokborok speaking communities in Tripura, India, have also undergone transformation over time. To examine the extent of these changes, this paper identifies the livelihood-based economic activities still practised by the Tripuri communities. It further investigates the spatial variation in use of material culture related to economic activities, socio-cultural practises among the Tripuris. Quantitative data were collected using a structured schedule through field survey across two blocks, Bokafa and Karbuk, covering eight Kokborok-speaking communities in the month of March 2025. Based on the data, descriptive and comparative analyses were made. The research focuses on major livelihood activities prevalent among the Tripuris: agriculture, hunting, livestock rearing, fishing, brewing, weaving, handcrafting, and rubber plantation. The findings of the study reveal that the Tripuris continue to engage in agriculture, primarily lowland paddy cultivation, with significant changes in tools and materials used. Traditional practises such as brewing, weaving, and livestock rearing persist as key livelihood activities, but the materials associated with them have evolved, with spatial variation across communities. In contrast, hunting and handcrafting have largely declined, excepting few households. Rubber plantation have emerged as a dominant economic activity, promoted by the government to encourage settled agriculture and biodiversity management. This shift have contributed to the decline of many traditional practises with only a small fraction continuing traditional ways of life and subsequently brought substantial changes ultimately affecting the material culture.
