The United Nations Educational, Scientific and Cultural Organization (UNESCO) launched the Man and the Biosphere (MAB) Programme in 1970. UNESCO’s MAB Strategy 2015-2025 ensures that all 686 biosphere reserves within the world network are working collectively on four common strategic objectives:
Conserve biodiversity, restore and enhance ecosystem services and foster sustainable use of natural resources;
Contribute to building sustainable, healthy, and equitable societies, economies, and thriving human settlements;
Facilitate sustainability science and education for sustainable development, and;
Support mitigation and adaptation to climate change and other aspects of global environmental change.
