Uttarakhand, often referred to as the "Land of the Gods," is not only known for its spiritual heritage but also its rich ecological diversity. This Himalayan state harbors a significant number of biosphere reserves that are part of Indias network aimed at conserving biodiversity while fostering sustainable development.
Introduction to Biosphere Reserves
Biosphere reserves are designated areas comprising terrestrial, marine, and coastal ecosystems that promote biodiversity conservation and sustainable utilization of natural resources. These reserves are recognized under UNESCO's Man and the Biosphere (MAB) Programme. Uttarakhand, with its diverse climatic zones and topographical variations, is home to two globally recognized biosphere reserves: Nanda Devi Biosphere Reserve and the Valley of Flowers Biosphere Reserve.
1. Nanda Devi Biosphere Reserve
