Abstract: Researchers review the indigenous knowledge of communities in MLFR and how this has helped in biodiversity conservation. Indigenous and local communities live in areas where substantial biodiversity resources are found and have made remarkable contributions to its sustainable conservation. They have used the resources for thousands of years and their cultures and knowledge are deeply rooted in the environment on which they depend. The Global Environment Facility (GEF) has been working closely with local communities since its inception, recognizing that effective public involvement of local communities is critical to the success of its projects. The Convention on Biological Diversity (CBD) also emphasizes the importance of working with indigenous peoples to respect, preserve and maintain traditional knowledge relevant for the conservation and sustainable use of biodiversity. Successful implementation of conservation projects affecting local communities can be guaranteed on a long-term basis only when there is consent from and collaboration with the communities.
