India is marking the International Day for Biosphere Reserves with renewed attention on the role of protected ecological landscapes in conserving biodiversity, strengthening climate resilience and supporting communities whose livelihoods depend on natural resources.
According to a backgrounder issued by the Ministry of Environment, Forest and Climate Change on November 2, India has 18 notified Biosphere Reserves, of which 13 are included in UNESCO's World Network of Biosphere Reserves.
Editorial Insight
Key Highlights
Important points readers should notice.
Issue/Event: International Day for Biosphere Reserves highlights biodiversity conservation and sustainable development.
Location: India.
Authority/Organisation: Ministry of Environment, Forest and Climate Change and UNESCO's Man and the Biosphere Programme.
Action Taken: The Environment Ministry published an overview of India's 18 notified Biosphere Reserves and ongoing conservation initiatives.
Impact: The reserves support wildlife habitats, ecological resilience, scientific research and sustainable livelihoods for communities.
These landscapes represent a wide range of ecosystems, including tropical forests, wetlands, mangroves, marine habitats and high-altitude deserts. They provide important habitats for wildlife and plant species while supporting communities through agriculture, traditional livelihoods, sustainable resource use and other economic activities.
The International Day for Biosphere Reserves is observed annually on November 3. The day was proclaimed by UNESCO to highlight the contribution of biosphere reserves to biodiversity conservation and sustainable development.
India's network includes internationally recognised landscapes such as the Nilgiri, Nanda Devi, Gulf of Mannar, Sundarbans, Similipal, Pachmarhi, Khangchendzonga, Agasthyamalai, Achanakmar-Amarkantak, Cold Desert and Panna Biosphere Reserves.
Editorial Analysis
Why This Matters
Biosphere reserves help protect ecosystems that support wildlife, human communities and essential natural resources. Their importance goes beyond conserving individual species. Forests, wetlands, coastal ecosystems and mountain habitats contribute to water availability, climate regulation, food security and local economic activity. The integrated approach also recognises that communities living around protected landscapes need sustainable livelihood opportunities. Conservation programmes are more likely to achieve long-term results when local residents participate in planning and responsible resource management. For India, strengthening these landscapes is important because the country contains a significant share of the world's recorded biodiversity despite having a relatively small share of global land area.
The country's 18 notified reserves cover different ecological regions. Some protect mountain ecosystems and high-altitude wildlife, while others conserve coastal habitats, coral reefs, seagrass beds, mangroves and tropical forests.
The Nilgiri Biosphere Reserve, which extends across Tamil Nadu, Kerala and Karnataka, is among India's most significant biodiversity landscapes. It supports species such as the lion-tailed macaque, Nilgiri tahr, elephants and tigers, alongside a wide variety of birds, plants and other wildlife.
The Gulf of Mannar Biosphere Reserve is another important ecological area. Its marine environment includes coral reefs, seagrass beds and mangroves, which support diverse marine life and sustain coastal communities.
India's Cold Desert Biosphere Reserve in Himachal Pradesh represents a very different ecological environment. Its high-altitude landscape supports species such as the snow leopard, Himalayan ibex and blue sheep, while local communities continue traditional livelihoods in challenging climatic conditions.
Biosphere reserves are different from national parks and wildlife sanctuaries in their broader approach. While national parks and sanctuaries primarily focus on protecting wildlife and habitats, biosphere reserves also seek to balance conservation with sustainable economic activity and community participation.
The framework generally includes three interconnected zones. The core area receives the highest level of protection for biodiversity and ecological processes. The buffer zone allows activities compatible with conservation, including research, education and regulated ecotourism. The transition area accommodates settlements and sustainable livelihoods.
This model is intended to demonstrate how environmental protection and human well-being can coexist rather than treating them as competing objectives.
The Ministry's backgrounder also highlights India's Biodiversity Conservation programme, under which financial assistance is provided to states for conservation and development activities in biosphere reserves. Implementation is undertaken through state forest departments and approved management plans.
Since 2022–23, the Ministry has piloted five-year Integrated Management Plans for four reserves: Nanda Devi, Pachmarhi, Dehang-Dibang and Agasthyamalai. These plans bring reserve authorities, research institutions and local communities together, with priorities including habitat restoration, biodiversity monitoring, scientific research and sustainable livelihoods.
The importance of these landscapes extends beyond wildlife protection. Healthy forests, wetlands and coastal ecosystems contribute to water security, food systems, carbon storage and resilience against climate-related pressures.
The Ministry has noted that India accounts for approximately 7–8% of recorded species worldwide while occupying about 2.4% of the Earth's land area. This biodiversity makes the conservation of natural habitats an important part of the country's environmental priorities.
However, notification or international recognition alone does not guarantee effective conservation. Long-term results depend on habitat protection, scientific monitoring, adequate funding, coordination among authorities and meaningful participation by local communities.
The observance therefore provides an opportunity to assess not only the size of India's biosphere reserve network but also the effectiveness of conservation and sustainable development efforts taking place within these landscapes.
