Tripura, a northeastern Indian state rich in cultural and ecological diversity, is home to 19 tribal communities whose lives are deeply intertwined with the natural environment. These communities have cultivated Traditional Ecological Knowledge (TEK) over generations, fostering sustainable living practices. However, modernization and socio-economic pressures have threatened both their cultural heritage and ecological balance. This paper explores how the integration of TEK into formal education can promote sustainable development in Tripura. By examining traditional practices such as jhum cultivation, biodiversity conservation, and medicinal plant use, the paper highlights the potential of TEK-based education to empower communities, preserve indigenous knowledge, and foster ecological resilience.
