There are living organisms all around us and we must make a conscious effort to preserve as well as conserve this biodiversity in our environment.

Simply put, Biosphere Reserves can be defined as widespread areas of bio-diversity wherein fauna and flora are protected.

‘Biosphere’ refers to water, land, and atmosphere that supply life on our planet. The word ‘reserve’ symbolizes that it is a special area designated for creating a balance between conservation and sustainable use.

You must not misinterpret the word ‘reserve’ to be a place that is set aside from human use and development. A biosphere reserve program also aims at studying human interaction with a particular area.

Biosphere reserves are a great example of community-based initiatives aimed towards the protection of our natural environment while also ensuring consistent healthy growth of the local economy.

It can include one or more National Parks or sanctuaries. Protection is granted to all the living organisms flourishing inside the boundaries of the reserve, including flora, fauna as well as the human communities who inhabit those regions.

Biosphere Reserves

The biosphere reserve network was launched in 1971 by UNESCO, two years after the initiation of MAB- Man and the biosphere program.

As per the law, these regions of environmental protection related to the International Union for Conservation of Nature (IUCN) Category V Protected areas.

  • Biosphere Reserve (BR) is an international designation by the United Nations Educational, Scientific and Cultural Organization (UNESCO) for representative parts of natural and cultural landscapes extending over large areas of terrestrial or coastal/marine ecosystems or a combination of both.
  • Biosphere Reserves tries to balance economic and social development and maintenance of associated cultural values along with the preservation of nature.
  • Biosphere Reserves are thus special environments for both people and nature and are living examples of how human beings and nature can co-exist while respecting each others’ needs.
  • Biosphere Reserve (BR) is not covered under any law.

The first biosphere reserve of the world was established in 1979. There are 701 Biosphere reserves across 124 countries in the world which also include 21 transboundary sites.

Criteria for Designation of Biosphere Reserve

  • A site must contain a protected and minimally disturbed core area of value of nature conservation.
  • Core area must be a bio-geographical unit and should be large enough to sustain a viable populations representing all trophic levels.
  • The involvement of local communities and use of their knowledge in biodiversity preservation.
  • Areas potential for preservation of traditional tribal or rural modes of living for harmonious use of the environment.

Structure of Biosphere Reserve

  • Core Areas:
    • It is the most protected area of a biosphere reserve. It may contain endemic plants and animals.
    • They conserve the wild relatives of economic species and also represent important genetic reservoirs having exceptional scientific interest.
    • A core zone is a protected region, like a National Park or Sanctuary/protected/regulated mostly under the Wildlife (Protection) Act, 1972. It is kept free from human interference.
  • Buffer Zone:
    • The buffer zone surrounds the core zone and its activities are managed in this area in the ways that help in the protection of the core zone in its natural condition.
    • It includes restoration, limited tourism, fishing, grazing, etc; which are permitted to reduce its effect on the core zone.
    • Research and educational activities are to be encouraged.
  • Transition Zone:
    • It is the outermost part of the biosphere reserve. It is the zone of cooperation where human ventures and conservation are done in harmony.
    • It includes settlements, croplands, managed forests, and areas for intensive recreation and other economic uses characteristics of the region.

Functions of Biosphere Reserve

  • Conservation:
    • Managing Biosphere Reserve’s genetic resources, endemic species, ecosystems, and landscapes.
    • It may prevent man-animal conflict eg. death of tiger Avni who was shot dead when she turned man-eater
    • Along with the wildlife, culture and customs of tribals are also protected
  • Development:
    • Promoting economic and human growth that is sustainable on a sociocultural and ecological level. It seeks to strengthen the three pillars of sustainable development: social, economic, and protection of the environment.
  • Logistic support:
    • Promoting research activities, environmental education, training, and monitoring in the context of local, national, and international conservation and sustainable development.

UNESCO Protected Biosphere Reserves

The World Network of Biosphere Reserves (WNBR) covers globally chosen protected areas. It consists of a vibrant and interactive network of sites of distinction.

It promotes the harmonious assimilation of people and nature for sustainable development in different ways. If one country declares one area as a biosphere reserve, it can nominate the same under the UNESCO’s Man and Biosphere (MAB) Programme. If UNESCO accepts the proposal of the government, the biosphere reserve will enter into the World Network of Biosphere Reserves (WNBR).

The UNESCO has introduced the designation ‘Biosphere Reserve’ for natural areas to minimize conflict between development and conservation. Biosphere Reserves are nominated by the national government which meets a minimal set of criteria under the Man and Biosphere Reserve Program of UNESCO.

Man and Biosphere Programme

  • Launched in 1971, UNESCO’s Man and the Biosphere Programme (MAB) is an intergovernmental scientific program that aims to establish a scientific basis for the improvement of relationships between people and their environments.
  • MAB combines natural and social sciences, economics, and education to improve human livelihoods and the equitable sharing of benefits, and to safeguard natural and managed ecosystems, thus promoting innovative approaches to economic development that are socially and culturally appropriate, and environmentally sustainable.

    Features of Biosphere Reserve
    • These are marked areas covering a larger area of land which includes multiple National Parks, Sanctuaries, and reserves as well
    • These places are meant for the conservation of biodiversity of a specific area
    • The 3 areas include Core, Buffer & Marginal. There’s no outside Species allowed.
    • It is used for Conservation & research purpose.
    • It is internationally recognized within the framework of UNESCO’s Man and Biosphere (MAB) program and nominated by national governments.
  2. Wildlife Sanctuary

    It is a declared area place where endangered species are kept. It restricts any activity that would put the protected animals in any state of undue stress or harm.

    Features of Wildlife Sanctuary
    • It is a natural area declared/protected by a governmental or private agency for the conservation of particular species.
    • It is strictly designated for the protection of wild fauna.
    • Only fauna is conserved. No outside activities are allowed
    • It comes under the category called “Protected Areas”. The Protected Areas are declared under Wildlife (Protection) Act, 1972.
    • The International Union for Conservation of Nature (IUCN) has defined  its Category IV type of protected areas
  3. National Park

    National parks are home to multiple species of birds and animals which is marked by Central And State Government for the purpose of conservation.

    Features of National Park
    • It is reserved land owned by the government.

    • Cutting, Grazing, and Outside Species Is not Allowed
    • It comes under the category called “Protected Areas”. The Protected Areas are declared under Wildlife (Protection) Act, 1972.
