Biosphere Reserves and Significance- UPSC Exam

This topic helps you to cover:

  • Biosphere reserves (BSR) in detail.
  • Understand UPSC pattern of Questionnaire.
  • Get a mental map of bio sphere reserves linking them with physiography, climate, tribes, flora and fauna of the region.

Salient Features of Biosphere Reserves:

  • It comprises of terrestrial, marine and coastal ecosystems
  • People are integral component of the system.
  • Their status is internationally recognized and ecosystem oriented.
  • Boundaries are circumscribed by legislation. Attention is provided on gene pool conservation.
  • They are nominated by the Center and under the sovereign jurisdiction of States where they are located.

Solution (a)

Main characteristics of Biosphere Reserves (BSR)

  • Aim at achieving 3 functions: Conservation, Development and logistic support.
