    • About Biosphere Reserves:
      • Biosphere reserves are areas of terrestrial and coastal/ marine ecosystems. They are multipurpose protected areas where both flora and fauna are protected.
      • They are ‘Science for Sustainability support sites.’ – promoting research in ecological conservation and environmental preservation.
      • The concept of Biosphere Reserves was launched in 1971 as a, part of the United Nations Educational, Scientific and Cultural Organization (UNESCO)’s ‘Man and Biosphere Programme’.
      • Man and Biosphere (MAB) Programme

      • There are 701 biosphere reserves in 124 countries
      • Aim of Biosphere Reserves:
        • conservation of genetic resources, species, and ecosystems;
        • scientific research and monitoring; and
        • Promoting sustainable development in communities of the surrounding region.
      • Zonation of Biosphere Reserves:
        • Divided into 3 zones:
          • Core Areas:
            • Includes protected areas-these act as reference points on the natural state of the ecosystems represented by the biosphere reserves
            • non-destructive research and other low-impact activities(such as ecotourism) are generally undertaken
          • Buffer Zone:
            • Surrounds or is contiguous to the core area.
            • Activities are organized, so they do not hinder the conservation objectives of the core area, but rather help to protect it.
            • It is used for cooperative activities compatible with sound ecological practices
            • Human activities are less intensive than that in the transition zone
          • Transition Zone or Area of Cooperation:
            • May contain a variety of agricultural activities, settlements, and other uses and in which local communities, management agencies, scientists, NGOs, and other stakeholders work together to manage and sustainably develop the area’s resources.
            • The term ‘area of cooperation’ underscores the role of cooperation as the main tool to achieve the objectives of the biosphere reserve.
          • About Biosphere Reserves in India:
            • There are 18 Biosphere Reserves in India. Of these, 11 are part of the World Network of Biosphere Reserves.
            • First Biosphere Reserve:Nilgiri Biosphere Reserve (Est. 1986)
            • Largest Biosphere Reserve:Gulf of Mannar
