Explanations:A biosphere reserve is a protected area designated by UNESCO under the Man and the Biosphere (MAB) program. These reserves are established to promote sustainable development and the conservation of biodiversity. They serve as model regions for sustainable development and are often used for research, education, and training.
In the context of Uttarakhand, the Nanda Devi Biosphere Reserve is a significant example of such a protected area. It was established in 1988 and covers an area of approximately 5,860.63 square kilometers. The reserve includes the Nanda Devi National Park and the Valley of Flowers National Park, both of which are UNESCO World Heritage Sites. The Nanda Devi Biosphere Reserve is known for its unique alpine and sub-alpine ecosystems, which support a wide range of flora and fauna, including several endangered species.
The Nanda Devi Biosphere Reserve is divided into three zones: the core zone, the buffer zone, and the transition zone. The core zone is strictly protected and is primarily used for research and monitoring. The buffer zone surrounds the core zone and allows for limited human activities, while the transition zone is the outermost area where sustainable development practices are encouraged.
Understanding the concept of biosphere reserves is crucial for students preparing for competitive examinations, as it involves knowledge of conservation efforts, biodiversity, and sustainable development practices. It is important to distinguish between different types of protected areas, such as national parks, wildlife sanctuaries, and biosphere reserves, as each has a specific purpose and management approach.
In Uttarakhand, while there are several national parks and wildlife sanctuaries, the Nanda Devi Biosphere Reserve is the only area designated as a biosphere reserve. This makes it a unique and important site for conservation and research, and it is a key area to remember when studying the geography and environmental conservation efforts of Uttarakhand.
