(b) Biosphere reserves are sites estabilished by countries and recognized under UNESCO’s Man and the Biosphere (MAB) Programme to promote sustainable development based on local community efforts and sound science. The programme of Biosphere Reserve was initiated by UNESCO in 1971. The purpose of the formation of the biosphere reserve is to conserve in situ all forms of life, along with its support system, in its totality, so that it could serve as a referral system for monitoring and evaluating changes in natural ecosystems. The first biosphere reserve of the world was established in 1979. There are 18 Biosphere Reserves in India established by the government that protect large areas of natural habitats. These areas are provided with the buffer zones that are open for some economic uses.
