Biosphere Reserves

Abstract: UNESCO Biosphere Reserves were first established under the Man and Biosphere Programme of UNESCO in the 1970s. Their mandate has expanded beyond conservation to include sustainable development and local capacity enhancement. As institutions under UNESCO, they also work on “building peace” by seeking to reconcile relations between peoples, and between people and the
