Biosphere Reserves in India 2026: List of 18 & 13 UNESCO Sites

Biosphere Reserves are an important topic in Indian Geography, Environment and General Knowledge. Questions about their names, locations, establishment years and UNESCO recognition are useful for competitive examinations, including JKSSB, JKPSC, SSC, Railway and other government recruitment exams.

For JKSSB aspirants, simply memorising the names is not enough. Questions can also test which reserve was established first, which is the latest UNESCO addition, which reserves extend across multiple states, and how Biosphere Reserves differ from National Parks and Wildlife Sanctuaries.

As of October 2026, India has 18 nationally designated Biosphere Reserves, of which 13 are included in UNESCO’s World Network of Biosphere Reserves (WNBR). The latest addition to UNESCO’s network from India is the Cold Desert Biosphere Reserve of Himachal Pradesh, recognised in September 2025.

What Is a Biosphere Reserve?

A Biosphere Reserve is a designated area that aims to conserve biodiversity while supporting sustainable development and the well-being of local communities. These areas may include forests, mountains, deserts, wetlands, coastal ecosystems and islands.

The main idea is to protect nature without ignoring the needs of people who depend on it. Scientific research, environmental education, traditional knowledge and sustainable livelihoods are therefore important parts of Biosphere Reserve management.

UNESCO promotes Biosphere Reserves through its Man and the Biosphere (MAB) Programme. However, a crucial exam point is that national designation and UNESCO recognition are different things. An Indian Biosphere Reserve does not automatically become part of UNESCO’s World Network.

Three Zones of a Biosphere Reserve

Biosphere Reserves generally have three interconnected zones.

1. Core Zone: This is the most strictly protected area. Its primary purpose is to conserve ecosystems, habitats and biodiversity. Human activities are highly restricted and are permitted only where consistent with applicable protection rules.

2. Buffer Zone: This surrounds or adjoins the core zone. Activities such as scientific research, environmental education, monitoring and compatible sustainable resource use may be allowed.

3. Transition Zone: This is generally the outermost area, where communities live and work. Sustainable agriculture, responsible tourism, traditional livelihoods and other environmentally compatible economic activities are encouraged.

JKSSB Tip: Remember the order from the most protected area outward: Core → Buffer → Transition.

Complete List of 18 Biosphere Reserves in India

The following table presents the nationally designated reserves, their locations and establishment years.

Important: The establishment year refers to national designation, not the year of inclusion in UNESCO’s World Network. This distinction is particularly important for the Cold Desert Biosphere Reserve.

The 13 UNESCO Biosphere Reserves in India

UNESCO recognition provides international recognition to sites that demonstrate the objectives of biodiversity conservation, sustainable development and research.

India’s 13 UNESCO-recognised Biosphere Reserves are listed below in chronological order of their inclusion in the World Network.

The five nationally designated reserves not currently listed in UNESCO’s World Network are Manas, Dibru-Saikhowa, Dehang-Dibang, Great Rann of Kutch and Seshachalam.

Do not confuse UNESCO Biosphere Reserve recognition with UNESCO World Heritage Site status. The designations have different purposes and criteria.

Its landscape includes high-altitude deserts, rugged mountains, glacial valleys and alpine lakes. The region has a cold, dry climate that supports specialised plants and animals adapted to extreme conditions.

The reserve includes areas associated with Pin Valley National Park and wildlife sanctuaries such as Kibber and Chandratal.

Latest update for October 2026: Cold Desert is India’s 13th UNESCO-recognised Biosphere Reserve. It is not India’s newest nationally designated reserve.

State-Wise Revision for JKSSB

State-based questions are common in competitive examinations. Revise the following associations carefully:

• Madhya Pradesh: Pachmarhi, Achanakmar-Amarkantak (shared with Chhattisgarh) and Panna.

• Tamil Nadu: Nilgiri (shared), Gulf of Mannar and Agasthyamalai (shared with Kerala).

• Assam: Manas and Dibru-Saikhowa.

• Uttarakhand: Nanda Devi.

• Meghalaya: Nokrek.

• West Bengal: Sundarbans.

• Odisha: Similipal.

• Arunachal Pradesh: Dehang-Dibang.

• Sikkim: Khangchendzonga.

• Gujarat: Great Rann of Kutch.

• Himachal Pradesh: Cold Desert.

• Andhra Pradesh: Seshachalam.

• Andaman and Nicobar Islands: Great Nicobar.

• Kerala: Agasthyamalai and Nilgiri (both shared with other states).

For Jammu and Kashmir exam preparation, also revise Himalayan ecology, national parks, wetlands, wildlife sanctuaries and environmental conservation in the Union Territory. These are related but separate General Knowledge topics.

Biosphere Reserve vs National Park vs Wildlife Sanctuary

These terms are often mixed up in multiple-choice questions.

A Biosphere Reserve is a broader conservation and sustainable-development landscape that may include protected areas and human settlements in different zones.

A National Park is a legally protected area established primarily for wildlife and ecosystem conservation, with activities regulated under applicable wildlife protection law.

A Wildlife Sanctuary is another legally protected category for wildlife conservation, with restrictions and permitted activities governed by law.

Remember that a Biosphere Reserve may contain a National Park or Wildlife Sanctuary. However, the three designations are not interchangeable, and UNESCO recognition is not automatically conferred on every protected area.

Latest Updates on Biosphere Reserves: October 2026

The key update for examination candidates is the inclusion of Cold Desert in UNESCO’s World Network in September 2025. It raised the number of UNESCO-recognised Indian Biosphere Reserves to 13.

India’s national list remains at 18 in the official information checked for this article. Panna remains the newest national designation, established in 2011.

UNESCO’s Man and the Biosphere Programme also continues to emphasise conservation, sustainable livelihoods, scientific research and community participation. Its Hangzhou Strategic Action Plan for 2026–2035 sets out priorities for the programme and its global network.

Exam caution: Do not write that India has 13 Biosphere Reserves in total. The correct distinction is 18 nationally designated reserves and 13 UNESCO-recognised sites.

Conclusion

Biosphere Reserves are an important part of environmental conservation and sustainable development in India. For JKSSB aspirants, the best approach is to prepare the complete list of 18 reserves, memorise their states and establishment years, and separately learn the 13 UNESCO-recognised sites.

Give extra attention to Nilgiri, Sundarbans, Gulf of Mannar, Great Nicobar, Panna and Cold Desert. These names help connect geographical locations with distinctive ecosystems and important dates.

Keep revising the facts alongside other environmental topics such as National Parks, Wildlife Sanctuaries, Ramsar Sites and biodiversity hotspots. A clear understanding of the differences between these categories will help you handle both direct factual questions and tricky statement-based MCQs in competitive examinations.
