Biosphere Reserves in India
What is a Biosphere Reserve?
A biosphere reserve refers to protected terrestrial or coastal ecosystems or a combination of both, which is intended to restore and conserve the biodiversity and its sustainable use. It aims to preserve the genetic diversity of the protected area by protecting the native flora and fauna and maintaining the traditional life style of inhabitants and promoting alternate livelihood for them.
The term biosphere reserve is an international designation offered by UNESCO to natural landscapes spreading over large terrestrial or coastal areas or a combination of both. Although a biosphere is a protected area, it is intended to fulfil three basic functions, which are as follows:
Besides this, a biosphere can be divided into three zones or we can say that a biosphere consists of three zones:
i) Core Zone: It is a legally protected undisturbed ecosystem in which human activities are strictly prohibited or not allowed. This zone may contain wild relatives of economic species and genetic reservoirs.
ii) Buffer Zone: It is the area that surrounds the core zone without any gap. In this area, limited human activities like research, education, study, etc., are allowed without affecting the core zone.
iii) Manipulation Zone: It is the outermost part of the biosphere reserve. A wide range of human activities are allowed at this zone without disturbing the ecosystem and with the permission and cooperation of biosphere reserve management and local residents. For example, cropping, recreation, human settlements, forestry, and resource gathering, etc. are allowed.
