Traditional Ecological Knowledge of Tribal Communities and Sustainability of Nature and Natural Resources in Pachmarhi Biosphere Reserve in India

Traditional ecological knowledge (TEK) continues to erode as a result of globalization and the homogenization of diverse cultures, yet it has helped to conserve natural resources and preserve nature for centuries. Biosphere reserves have been established in regions where both cultural and natural resource assortments are deemed rich. The present study was carried out in the Pachmarhi Biosphere Reserve (PBR) of India with the major objective of investigating the TEK of local communities with respect to the sustainability of nature and natural resources. Through both a questionnaire and interviews with tribal groups in PBR, a total of 128 plant species were documented, of which the highest number of species (52%) was used for food, followed by medicine (40%), cultural practices (13%), and construction of houses (11%). Apart from the collection of plants from the adjacent forests for their sustenance, the tribal groups engaged in various other activities including farming practices, maintenance of home gardens, soil and water conservation, and continuance of sacred groves. The nature and natural resource-based livelihood and conservation activities of tribal groups involve specific cultural practices and customary norms. This study reveals that the traditional knowledge of tribal communities offers unique ideas for developing and contributing to more effective sustainable management practices and nature conservation. It has a great potential to strengthen the agriculture and health sectors, as the tribal communities have accumulated a fair amount of knowledge in such sectors.
