    Study Notes

    • Biodiversity is the variety of life on Earth.
    • It is the product of 4 billion years of evolution.
    • Biodiversity is measured by species diversity, genetic diversity, and variety of ecosystems.
    • Species diversity includes a wide range of organisms, such as various animals like tigers, elephants, and birds and diverse plants.
    • Genetic diversity refers to the genetic variations within species, such as the differences in human populations.
    • Ecosystem diversity refers to the different types of ecosystems, such as terrestrial and aquatic. Specific examples of terrestrial ecosystems are evergreen forests, grasslands, deciduous forests, and alpine forests. Examples of aquatic ecosystems include rivers, lakes, and ponds and marine/coastal ecosystems like mangroves and coral reefs.
    • India has a vast amount of domesticated biodiversity, with 50,000 varieties of rice and eight breeds of buffaloes.
    • India is among the 17 mega-diversity countries globally.
    • 8% of the world's biodiversity is found in just 2% of the Earth's surface in India.
    • India has 16 major forest types, covering 21% of the country.
    • India has 30,000 cultivated plants.
    • India has 11,058 endemic plant species and high endemicity for various groups such as amphibians (61% of species), reptiles (47%), and a range of fish.
    • India has 45,500 plant species (including 17,527 flowering plants), 91,200 animal species (with 57,000 insects being the highest), 4,000 molluscs, 2,546 fish, 460 reptiles, 248 amphibians, 1,232 birds, 397 mammals, and 20,000 invertebrates.
    • India has 8,000 medicinal plants used in 50,000 herbal formulations.
    • India has two major biodiversity hotspots: Western Ghats and North East India.
    • Criteria for biodiversity hotspots include supporting over 1,500 endemic species, having lost over 70% of original habitats, and with high numbers of vertebrates and flowering plants in a small percentage of the land area.
    • There is a loss of biodiversity in India and globally.
    • The natural rate of extinction of species is one species per year, however the current rate of extinction is 1 species per hour which is 10,000 times higher than the natural rate.
    • The main threats to biodiversity include habitat loss, over-exploitation of species, pollution, and invasive species. Loss of wildlife corridors are also detrimental to biodiversity.
    • Human-wildlife conflicts and trade in wildlife species, such as elephants and tigers, also pose serious threats.
    • There are 102 national parks, 515 wildlife sanctuaries, 4 conservation reserves, 47 community reserves, 41 tiger reserves, 25 elephant reserves, 25 Ramsar sites, 465 important bird areas, and 5 UNESCO heritage sites within protected areas.
    • Conservation efforts include the Chipko movement, silent valley saving efforts, and the project elephant conservation initiatives while recognizing that conservation needs to be sustainable to sustain human and wildlife habitats.
    • International conventions support biodiversity conservation through the Biodiversity Convention, the Ramsar Convention, the World Heritage Convention, and the Convention on International Trade in Endangered Species of Wild Flora and Fauna.
    • National conservation strategies include the Indian Forest Act, Environmental Protection Act, Forest Conservation Act, Fisheries Act, Wildlife Protection Act, Biodiversity Act, and Maritime Zones Act.
    • Solutions for conserving biodiversity involve preserving natural capital, producing better with environmentally sustainable practices, and consuming more wisely. Equitable resource governance is also key.
