- Biosphere reserves are designated under UN‐ ESCO's Man and the Biosphere (MAB) Programme to promote sustainable development by integrating conservation, research, and local community involvement. - The typical structure of a biosphere reserve consists of three main zones: 1. Core Zone A strictly protected area for conservation, representing natural ecosystems. Human activity is minimal or prohibited. 2. Buffer Zone Surrounds or adjoins the core area. Activities are managed to be compatible with conservation, such as research, environmental education, tourism, and training. 3. Transition Zone The outermost part of the reserve. It is an area of cooperation where sustainable resource management practices and human settlements are allowed, encouraging socio-economic development that is ecologically sustainable.
