In the present modern era, the technology is moving forward at a greater pace. As an aftermath of that the local indigenous knowledge are dwindling down and slowly getting extinct. Therefore there is an urgent need for protection and integration of the indigenous knowledge for the sustainable development of the local people and local ecological resource management. Keeping this in mind the present study was conducted in order to explore the indigenous knowledge utilization index along with the socio-economic, socio-personal and psychological attributes of the knowledge users and their relationship with each other. The present study was conducted in the village of Aloobari Jungle Busty, and Aloobari Rai Gaon, under the block Jorebunglow-Sukhiapokhari of Darjeeling district in West Bengal due to the dominance of aborigines and their ample utilization of indigenous knowledge base in this area. Purposive as well as multi-stage random sampling procedure was followed in the present study. The Indigenous knowledge utilization index and the socio-personal, socio-economic and socio-psychological attributes of the indigenous technological knowledge users were systematically operationalised and measured with the help of the slightly modified pre-constructed measurement scales.
