Explanation:

Biosphere reserves are areas of terrestrial and coastal ecosystems promoting solutions to reconcile the conservation of biodiversity with its sustainable use. They are internationally recognized, nominated by national governments and remain under sovereign jurisdiction of the states where they are located.

•  Launched in 1971, UNESCO‘s Man and the Biosphere Programme (MAB) is an Intergovernmental Scientific Programme that aims to establish a scientific basis for the improvement of relationships between people and their environments.MAB combines the natural and social sciences, economics and education to improve human livelihoods and the equitable sharing of benefits, and to safeguard natural and managed ecosystems, thus promoting innovative approaches to economic development that are socially and culturally appropriate, and environmentally sustainable. Its World Network of Biosphere Reserves currently counts 701 sites in 124 countries all over the world, including 21 transboundary sites. Hence Statement 2 is not correct.
• There are 18 Biosphere Reserves in the country. Under the MAB Programme of the UNESCO, India has 11 internationally recognised biosphere reserves.
