Biosphere Reserve (BR) is a United Nations Educational, Scientific, and Cultural Organization’s (UNESCO) international designation for representative parts of natural and cultural landscapes spanning large areas of terrestrial or coastal/marine ecosystems, or a combination of both. Countries establish biosphere reserves, which are recognized by UNESCO's Man and the Biosphere (MAB) Programme, to promote sustainable development based on local community efforts and sound science. UNESCO launched the Biosphere Reserve programme in 1971. In this article, we will discuss Biosphere Reserves which will be helpful for UPSC exam preparation.

What are Biosphere Reserves?

• Biosphere Reserves are large areas of bio-diversity where fauna and flora are protected.
• Biosphere reserves serve as "learning environments for sustainable development."
• They serve as test beds for interdisciplinary approaches to understanding and managing changes and interactions between social and ecological systems, such as conflict resolution and biodiversity management.
• They are locations that provide local solutions to global problems. Terrestrial, marine, and coastal ecosystems are all included in biosphere reserves.
• Each site promotes solutions that balance biodiversity conservation with sustainable use.
• National governments nominate biosphere reserves, which remain under the sovereign jurisdiction of the states in which they are located.
• There is no law that governs the Biosphere Reserves (BR).
• The world's first biosphere reserve was established in 1979; since then, the network of biosphere reserves has grown to 738 in 134 countries worldwide.
• India currently has 18 notified biosphere reserves.

Characteristics of Biosphere Reserves

• Biosphere Reserves are large areas of bio-diversity where fauna and flora are protected.
• The term "biosphere" refers to the water, land, and atmosphere that sustain life on our planet.
• The term "reserve" denotes a special area designated for achieving a balance between conservation and sustainable use.
• A biosphere reserve programme will also study human interaction with a specific area.
• Biosphere reserves are an excellent example of community-based initiatives aimed at protecting our natural environment while also ensuring consistent, healthy economic growth in the local area.
• It may include one or more national parks or wildlife refuges.
• All living organisms flourishing within the reserve's boundaries, including flora and fauna, as well as human communities, are protected.
• Each Biosphere Reserve is a protected area of land and/or coastal environments in which people play an important role.
• They form a global network linked by international understanding for the exchange of scientific information.
• The BR network includes significant examples of biomes from around the world.
• BRs are typical examples of natural biomes.
• BRs protect unique biodiversity communities or areas with unusual natural features of exceptional interest.
• Traditional land-use patterns have resulted in harmonious landscapes in BRs.
• There are examples of modified or degraded ecosystems that can be restored to more natural conditions in BRs.
• BRs typically have a non-manipulative core area, as well as areas for baseline measurements, experimental and manipulative research, education, and training. Where these areas are not contiguous, they can be grouped together to form a cluster.

Functions of Biosphere Reserve

• Local communities and all interested stakeholders are involved in the planning and management of Biosphere Reserves. They combine three major "functions":
  • Biodiversity and cultural diversity conservation.
  • Sustainable socio-cultural and environmental economic development.
  • Support for logistics and development through research, monitoring, education, and training.
• These three functions are carried out through the three main zones of the Biosphere Reserves.

Conservation

• Managing the genetic resources, endemic species, ecosystems, and landscapes of the Biosphere Reserve.
• It may prevent man-animal conflict, such as the death of tiger Avni, who was shot dead after turning man-eater.
• Tribal culture and customs are also protected, in addition to wildlife.

Development

• Promoting sociocultural and ecologically sustainable economic and human growth.
• It aims to strengthen the three pillars of sustainable development: social, economic, and environmental protection.

Logistics Support

• Promoting conservation and sustainable development through research, environmental education, training, and monitoring on a local, national, and international scale.
• Sharing of research-generated knowledge through site-specific training and education.
• Development of community spirit in natural resource management.

Beneficiaries

• Local people and the ecological resources of the Biosphere Reserves are direct beneficiaries.
• The world community is an indirect beneficiary.

Indian Approach

• This ecological diversity is what distinguishes India as one of the world's mega-diversity regions.
• At least one Biosphere Reserve is being designated in each of the Biogeographic Provinces.

National Biosphere Reserve Programme

• The UNESCO Man and Biosphere (MAB) programme guides the Biosphere Reserve Programme, as India is a signatory to the landscape approach supported by the MAB programme.
• The Government of India has been implementing a scheme called Biosphere Reserve since 1986, in which financial assistance is given in a 90:10 ratio to the North Eastern Region States and three Himalayan states, and in a 60:40 ratio to other states for the maintenance, improvement, and development of certain items.
• It ensures local residents' participation in effective management and to devise methods of improving local residents' livelihoods through sustainable use.
• The Management Action Plan is created by the State Government and is approved and monitored by the Central MAB Committee.
• Under UNESCO's Man and Biosphere Reserve Program, national governments nominate Biosphere Reserves that meet a minimum set of criteria.

Objectives of National Biosphere Reserve Programme

• To conserve the diversity and integrity of plants and animals within natural ecosystems;
• To safeguard genetic diversity of species on which their continued evolution depends;
• To provide areas for multi-faceted research and monitoring;
• To provide facilities for education and training; and
• To ensure sustainable use of natural resources through most appropriate technology.

Criteria for Selection of Biosphere Reserves

• The International Co-ordinating Council (ICC) of the MAB programme selects biosphere reserves for inclusion in the Network.
• States are encouraged to assess and improve the adequacy of any existing biosphere reserve, and to propose extensions as needed, to allow it to function fully within the Network.
• Biosphere reserves established prior to the adoption of the current Statutory Framework are considered to be part of the Network. As a result, the provisions of the Statutory Framework apply to them.

Primary Criteria

• A site must have a protected and minimally disturbed core area of conservation value.
• It should include more land and water suitable for research and demonstration of sustainable research and management methods
• The core area must be a bio-geographical unit large enough to support viable populations at all trophic levels.

Secondary Criteria

• Rare and endangered species habitats.
• Areas with a wide range of soil and microclimatic conditions, as well as indigenous biota.
• Participation of local communities and utilisation of their knowledge in biodiversity conservation.
• Areas with the potential to preserve traditional tribal or rural ways of life for the harmonious use of the environment.

Structure and Design of Biosphere Reserves

Biosphere reserves are traditionally organised into three interconnected zones to carry out the complementary activities of biodiversity conservation and sustainable use of natural resources, known as the core area, the buffer zone, and a transition area or 'area of cooperation.'

Core Area

• It is a strictly protected zone that helps to conserve landscapes, ecosystems, species, and genetic variation.

Buffer Zone

• It encircles or adjoins the core area(s) and is used for activities consistent with sound ecological practises, such as scientific research, monitoring, training, and education.

Transition Area

• Communities in the transition zone promote socio-culturally and ecologically sustainable economic and human activities.

Importance of Biosphere Reserves

• Biosphere reserves contribute to the region's environmental, economic, and social sustainability by encouraging the wise use of natural and human resources.
• They offer practical solutions for resolving land use conflicts and protecting biological diversity.
• Through national and international networks, a biosphere reserve area gains access to information, expertise, support, and funding.
• Biosphere reserves promote diverse local economies and the revitalization of rural areas.
• The biosphere concept can be used to guide and strengthen projects that improve people's livelihoods.
• Biosphere reserves stimulate academic and government research into local issues and problems.
• Biosphere reserves serve as research and demonstration sites for conservation and sustainable development, providing lessons that can be applied elsewhere.
• Biosphere reserves highlight the area's uniqueness and help residents and visitors develop a sense of place.
• The designation of a biosphere reserve can raise awareness of environmental and development issues among local residents, citizens, and government officials.
• A biosphere reserve serves as a focal point for stakeholder collaboration and volunteerism.

How Biosphere Reserves are Different from Protected Areas?

Biosphere Reserve is not meant to replace existing protected areas; rather, it broadens the scope of the traditional approach to protection and strengthens the Protected Area Network. However, Biosphere Reserves differ from protected areas in that they place a greater emphasis on:

• Conservation of overall biodiversity and landscape, rather than specific flagship species, to ensure that natural and evolutionary processes can continue unhindered.
• Landscapes, habitats, species, and land races are all examples of BR components.
• Developmental activities, as well as conflict resolution/mitigation between development and conservation,
• Increase in the number of stakeholders, particularly local people's participation and training, when compared to the features of the scheme on Wildlife Sanctuaries and National Parks.
• Sustainable environmental development and long-term coordination among various development organisations and agencies
• Research and monitoring to better understand the structure and operation of ecological systems, as well as their response to human intervention.

Conclusion

The goal of establishing a biosphere reserve is to preserve all forms of life in their entirety, including their support systems, in order to serve as a referral system for monitoring and evaluating changes in natural ecosystems. It should be noted that BRs are not a replacement or alternative, but rather a supplement to existing protected areas.
