Structure of Biosphere Reserves 

UNESCO Biosphere Reserve in India has three zones: core area, buffer zone, and transition area. Check the details of the structure of biosphere reserves and their major elements.

Core Areas

The Core Area is the safest area of a Biosphere Reserve and may include endemic animals and plants. It is the most suitable area for numerous animal species and plants and may include centers of endemism. Core areas of a Biosphere Reserve often conserve the wild relatives of the economic species. A core area is a sanctuary or national park regulated/protected under the Wildlife Act 1972.

Buffer Zone

To simply put, the buffer zone surrounds or adjoins the core zone. Here the activities and uses are managed in such a way that helps protect the natural condition of the core zones. Here the activities and uses include demonstration, restoration sites to increase the value of the resources, tourism, limited recreation, grazing, fishing, etc., which are permitted to reduce their impact on the core zone.

Transition Zone

This area is the outermost part of the Biosphere Reserve. In this zone greatest activity is permitted to increase human and economic development that is sustainable. This includes croplands, settlements, and managed forests for economic uses.

The government nominates Biosphere Reserves that meet the minimal criteria and conditions for inclusion in the world network of Biosphere Reserves under UNESCO’s Man and Biosphere Reserve. According to UNESCO, as of July 2021, there are 714 Biosphere Reserves across 129 countries in the world.

Man and Biosphere Programme- It was launched in 1971.

MAB combines economics, social sciences, and education to better human livelihoods and protect natural and managed ecosystems. The national government nominates Biosphere Reserves for inclusion in the world network of biospheres. Then the committee of the MAB program recognizes the Biosphere Reserve after fulfilling the criteria.
