- Biosphere reserves are ‘learning places for sustainable development’.
- They are sites for testing interdisciplinary approaches to understanding and managing changes and interactions between social and ecological systems, including conflict prevention and management of biodiversity.
- They are places that provide local solutions to global challenges. Biosphere reserves include terrestrial, marine and coastal ecosystems.
- Each site promotes solutions reconciling the conservation of biodiversity with its sustainable use.
Biosphere Reserves involve local communities and all interested stakeholders in planning and management. They integrate three main “functions”:
- Conservation of biodiversity and cultural diversity
- Economic development that is socio-culturally and environmentally sustainable
- Logistic support, underpinning development through research, monitoring, education and training
These three functions are pursued through the Biosphere Reserves’ three main zones

Core Areas
It comprises a strictly protected zone that contributes to the conservation of landscapes, ecosystems, species and genetic variation
Buffer Zones
It surrounds or adjoins the core area(s), and is used for activities compatible with sound ecological practices that can reinforce scientific research, monitoring, training and education.
Transition Area
The transition area is where communities foster socio-culturally and ecologically sustainable economic and human activities.
Man and the Biosphere (MAB) Programme (UNESCO)
- The MAB Programme is an intergovernmental scientific programme that aims to establish a scientific basis for enhancing the relationship between people and their environments. It combines the natural and social sciences with a view to improving human livelihoods and safeguarding natural and managed ecosystems, thus promoting innovative approaches to economic development that are socially and culturally appropriate and environmentally sustainable.
- The World Network of Biosphere Reserves currently counts 738 sites in 134 countries all over the world, including 22 transboundary sites.

- Biosphere reserves are nominated by national governments and remain under the sovereign jurisdiction of the states where they are located. Biosphere Reserves are designated under the intergovernmental MAB Programme by the Director-General of UNESCO following the decisions of the MAB International Coordinating Council (MAB ICC). Their status is internationally recognized.
