Observed annually on November 3, the International Day for Biosphere Reserves was established by UNESCO in 2021 to highlight the vital role these areas play in balancing biodiversity conservation with sustainable human development. Unlike strict national parks, biosphere reserves function as living laboratories divided into core, buffer, and transition zones where local communities, scientists, and industries collaborate on sustainable resource management, ecotourism, and climate resilience. The day underscores the importance of protecting fragile ecosystems while supporting local livelihoods, drawing global attention to ecological preservation networks like India’s diverse biosphere reserves ranging from the Western Ghats to the Himalayas.
