UNESCO Man and the Biosphere (MAB) is an intergovernmental programme that aims to establish a scientific basis for enhancing the relationship between people and their environments. The World Network of Biosphere Reserves is an interactive network of sites of excellence that foster harmony between people and nature for sustainable development, respect for cultural values, and society’s ability to cope with change. There are 748 biosphere reserves in 134 countries, including 23 transboundary sites. Sites can be proposed by all Member States and Associate Members of UNESCO. Biosphere reserves are nominated by national governments and designated under the intergovernmental MAB Programme following the decisions of the MAB International Coordinating Council.
