Question

Write about the different zones of a Biosphere Reserve and their significance. Also, prepare a list of all the Biosphere Reserves in India.

Accepted Answer

A Biosphere Reserve is a large, protected area of land that aims to conserve biodiversity, promote sustainable development, and demonstrate a balanced relationship between humans and the biosphere. Biosphere is divided into three zones, i.e., core zone, buffer zone and transition zone.

Core zone: It is the innermost zone that is strongly prohibited for human activities. It acts as a safe place for rare and endangered species to live undisturbed, and it maintains the natural environment as it is, without human interference. Scientific research and monitoring activities are typically conducted in this zone to study natural processes and ecological dynamics.

Buffer zone: The buffer zone is like a middle ground between the core zone and the outermost zone in the Biosphere Reserve. Here, human activities are permitted but controlled to make sure they are sustainable. Buffer zones often include inhabited areas, agricultural lands, and community-based conservation initiatives. They serve to minimise human impacts on the core area and promote sustainable development practices.

Transition zone: This is the outermost zone of the Biosphere Reserve and includes areas where sustainable development activities are encouraged. It aims to promote economic development, cultural preservation, and sustainable land use practices. In this zone, conservation efforts are integrated with activities such as agriculture, forestry, tourism, and education to support local communities and their livelihoods.
