International Day for Biosphere Reserve is celebrated on November 3 each year to raise awareness of the importance of biosphere reserves and to promote their conservation and sustainable use. 
• On the second anniversary, it is important to reflect on the progress made in conserving and sustainably using these vital ecosystems.

How many biosphere reserves are there in the world?

• According to UNESCO, there are currently 748 biosphere reserves across 134 countries, including 22 transboundary sites.

What are the three levels of biosphere reserves?

• Core Zone: Strictly protected zone, providing habitat for flora and fauna, and protecting water, soil, air, and biota as a whole ecosystem. 
• Buffer Zone: Surrounding the core zone, where people live and work in harmony with nature and functions as a laboratory for scientists to study nature, and for training and education. 
• Transition Zone: The outermost zone, the place where communities practice socio-culturally and ecologically sustainable human activities.

Significance of Biosphere Reserves 

• UNESCO: United Nations Educational, Scientific and Cultural Organisation (UNESCO) biosphere reserves are living jewels of land, coastal and marine ecosystems, scattered across the globe, where nature and humans come together creating a symphony of life.
• UN: These are also supported by other United Nations (UN) agencies, like the United Nations Development Programme, the United Nations Environment Programme, as well as the International Union for Conservation of Nature. 
• Vital Reserves: Biosphere Reserves are important in preserving ecosystems, fighting against climate change (world’s carbon sinks helping to absorb carbon dioxide from the atmosphere) , protection of biodiversity, ensuring the sustainable use of natural resources, and providing opportunities for sustainable economic development. 

Conservation Efforts at Local Level

• Sundarban Biosphere Reserve: Here local communities are working together to manage mangrove forests and protect the biodiversity of the region.
• Gulf of Mannar Biosphere Reserve: Here local communities, including women, are contributing towards conservation efforts by forming self-help groups, while the youth are getting engaged in eco-tourism.The Gulf of Mannar Biosphere Reserve Trust employs ‘plastic checkpoints’ to collect and recycle waste for road construction.

What are the challenges faced by Biosphere Reserves?
