UNESCO defines a Biosphere Reserve (BR) as a natural landscape that covers a large area of terrestrial, coastal, marine or a combination of these ecosystems. The purpose of creating biosphere reserves is to conserve biodiversity, protect the culture and tradition, and also maintain the economic development of the area. The establishment of biosphere reserves is guided by the Man and Biosphere (MAB) program of UNESCO. India has 18 Biosphere Reserves, which we will learn more in detail in this blog.
The core zone must include an appropriate environment for various plants and animals, including predators and endemism.
This zone often preserves economic species and also represents relevant genetic reservoirs wit exceptional scientific interest.
While realizing that perturbation is a key ingredient of the ecosystem, this area is to be protected from human innovation and pressures external to the system.
The buffer zone surrounds the core zone. The activities of this area are managed in a way to help the core zone to remain in its natural condition.
The activities include restoration, fishing, demonstration sites, tourism, grazing, recreation, etc which are permitted to decrease its impact on the core zone.
Educational activities and researches are to be carried out effectively. Human activities are likely to continue if it does not unfavorably influence biological diversity.
The transition zone is the outermost portion of the biosphere reserve. It is a zone of cooperation where management and conservation skills are used and managed with concern to the biosphere reserve.
This includes croplands, recreation areas, settlements, managed forests and other economic uses specialized in this region.
