Biosphere Reserves: A Bridge Between Nature and People
UPSC IAS/BPSC | GS Paper 3 | Environment & Ecology |
Why in News?
The International Day for Biosphere Reserves is observed every year on 3 November to highlight the importance of protecting biodiversity while promoting sustainable development.
According to the Ministry of Environment, Forest and Climate Change (MoEFCC), India has 18 notified Biosphere Reserves, of which 13 are included in UNESCO’s World Network of Biosphere Reserves (WNBR). These reserves represent diverse ecosystems, ranging from tropical forests and mangroves to coral reefs and high-altitude deserts.
What Are Biosphere Reserves?
Biosphere Reserves are specially designated areas that aim to conserve biodiversity while allowing local communities to pursue sustainable livelihoods.
They protect natural ecosystems, preserve genetic resources, and promote the responsible use of biological resources. Unlike conventional protected areas, they focus on balancing environmental conservation with the social and economic needs of people.
The concept is supported by UNESCO’s Man and the Biosphere (MAB) Programme, launched in 1971. The program promotes scientific research and sustainable development by improving the relationship between people and nature.
Three Major Functions of Biosphere Reserves
Biosphere Reserves perform three interconnected functions:
- Conservation: Protect biodiversity, genetic resources, ecosystems, and landscapes, including cultural diversity.
- Sustainable Development: Promote economic activities that are environmentally responsible and respect local traditions.
- Scientific Support: Encourage research, environmental monitoring, education, training, and the exchange of knowledge.
Three Zones of a Biosphere Reserve
A Biosphere Reserve is divided into three zones to balance conservation with human activities.
| Zone | Key Features |
|---|---|
| Core Zone | Strictly protected area for conserving ecosystems, wildlife, and genetic diversity. Human activities are highly restricted. |
| Buffer Zone | Surrounds or adjoins the core area. Allows activities such as research, environmental education, and regulated ecotourism. |
| Transition Zone | Outer area where local communities live and undertake sustainable activities such as agriculture, forestry, and tourism. |
This zonation model allows nature to remain protected while communities continue to benefit from natural resources responsibly.
India's Biosphere Reserves: List of All 18 Reserves
India is one of the world's 17 mega-biodiverse countries. Despite occupying only 2.4% of the Earth's land area, it accounts for approximately 7–8% of recorded species worldwide.
To protect this rich natural heritage, India has established 18 biosphere reserves. Of these, 13 are part of UNESCO's World Network of Biosphere Reserves.
Global Network of Biosphere Reserves
UNESCO's World Network of Biosphere Reserves includes 797 Biosphere Reserves across 145 countries, according to the information provided in the PIB release.
These reserves are important not only for biodiversity conservation but also for supporting communities and strengthening resilience against climate change.
Biosphere Reserves vs National Parks and Wildlife Sanctuaries
Although all three contribute to biodiversity conservation, their approach differs.
- National Parks and Wildlife Sanctuaries: Primarily focus on protecting wildlife and their natural habitats.
- Biosphere Reserves: Follow a broader approach by combining biodiversity conservation, scientific research, and sustainable development for local communities.
Thus, biosphere reserves act as living laboratories where conservation and human well-being can progress together.
Government Initiatives for Biosphere Reserve Conservation
The Ministry of Environment, Forest and Climate Change implements the Biodiversity Conservation Scheme under the broader umbrella scheme, Conservation of Natural Resources and Ecosystems.
Key features include:
- Financial Assistance: Grants are provided to states for conservation and development activities under approved management plans.
- Cost Sharing: Funding is shared between the Centre and states in a 60:40 ratio for other states and 90:10 for Northeastern and Himalayan states.
- Integrated Management Plans: Since 2022–23, five-year plans have been piloted for Nanda Devi, Pachmarhi, Dehang-Dibang, and Agasthyamalai.
- Community Participation: These plans encourage cooperation among reserve authorities, research institutions, and local communities for habitat restoration, biodiversity monitoring, and sustainable livelihoods.
Community Participation: Turning an Invasive Plant into an Opportunity
Conservation becomes more effective when local communities become active partners rather than passive beneficiaries.
An inspiring example comes from the Nilgiri Biosphere Reserve, where Indigenous communities use uprooted Lantana vines to create elephant sculptures, furniture, and handicrafts.
This initiative serves two purposes: it creates livelihood opportunities for local artisans and helps raise awareness about invasive plant species.
In 2021, 125 life-sized elephant sculptures made from Lantana were displayed in London, bringing international attention to this creative conservation effort.
What is Lantana camara?
Lantana camara is an invasive shrub that spreads rapidly and forms dense thickets. It competes with native plants, reduces biodiversity, and can alter natural fire patterns. Its removal is difficult because it grows back quickly.
The initiative demonstrates how an environmental challenge can be turned into an opportunity for community participation and sustainable livelihoods.
Challenges in Managing Biosphere Reserves
Despite their importance, biosphere reserves face several challenges:
- Habitat Degradation: Deforestation, infrastructure development, and land-use changes threaten natural ecosystems.
- Climate Change: Rising temperatures, extreme weather events, and changing rainfall patterns affect sensitive habitats.
- Human-Wildlife Conflict: Increasing pressure on natural habitats can bring people and wildlife into conflict.
- Invasive Species: Species such as Lantana camara threaten native vegetation and ecological balance.
- Limited Community Participation: Conservation efforts may face difficulties when local communities do not receive adequate livelihood support or decision-making opportunities.
Way Forward: Making Conservation People-Centric
India's Biosphere Reserves can become stronger models of sustainable development through a combination of scientific research, community participation, and effective governance.
- Strengthen habitat restoration and biodiversity monitoring.
- Promote sustainable tourism and livelihood opportunities for local communities.
- Combine traditional ecological knowledge with modern scientific research.
- Improve coordination among government agencies, research institutions, and local stakeholders.
- Strengthen climate-resilient conservation strategies and control invasive species.
Conclusion
Biosphere Reserves demonstrate that protecting nature does not have to come at the cost of human development. They provide a model in which biodiversity conservation, scientific research, and local livelihoods support one another. India's 18 Biosphere Reserves are more than protected landscapes; they are living examples of how people and nature can thrive together.
