    Prelims level: EnviStats India 2024 Report and its highlights

    Why in the News?

    • The Ministry of Statistics and Programme Implementation (MoSPI) has released the “EnviStats India 2024: Environment Accounts” Report.

    What is the EnviStats India 2024 Report?

    • The EnviStats India 2024 Report, released by the MoSPI, is the 7th consecutive publication.
    • It compiles environmental-economic accounts based on the System of Environmental-Economic Accounting (SEEA) Framework.
    • This framework provides a global standard for integrating environmental data with economic statistics, offering insights into the country’s natural resources, ecosystems, and environmental sustainability efforts.

    Key Highlights:

    Details
    Protected Areas (SDG 13 & SDG 15) – 72% increase in the number of Protected Areas (2000-2023)
    – 16% increase in the area of Protected Areas, reflecting biodiversity conservation efforts.
    Mangrove Cover (SDG 13 & SDG 15) – 8% increase in mangrove cover (2013-2021), highlighting positive growth in coastal ecosystem protection.
    Ocean Accounts (SDG 14: Life below Water) – Introduced for the first time, covering the extent and condition of ocean ecosystems.
    Energy Use & Physical Asset Accounts (SDG 7: Affordable and Clean Energy & SDG 13: Climate Action) – Includes Physical Asset Accounts and Physical Supply and Use Tables for Energy, aligned with SEEA-Energy Framework, and data from ministries like Coal and Petroleum.
    Soil Nutrient Index (SDG 2: Zero Hunger) – Updated data on Soil Nutrient Index based on the Soil Health Card 2023-24, reflecting soil health and agricultural sustainability.
    Biodiversity & Species Richness (SDG 15: Life on Land) – Data on faunal and floral diversity, including endangered species like Leopards and Snow leopards, connecting to biodiversity conservation.

    Policy Recommendations  

    The EnviStats India 2024 Report suggests several policy directions based on its findings:

    • Biodiversity Protection: Strengthen community-led conservation and expand protection of critical ecosystems.
    • Ocean Ecosystem Management: Use Ocean Accounts for sustainable marine resource management and pollution control.
    • Soil Health: Encourage sustainable farming practices and better soil management, leveraging Soil Health Cards for improved productivity.
    • Integrated Planning: Focus on species conservation, habitat restoration, and genetic conservation through data-driven planning.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Brain mapping of fruit flies and its applications

    Why in the News?

    Researcher have successfully mapped the entire brain of an adult fruit fly, marking the first time researchers have created such a detailed map of an adult animal’s brain.

    How Was the Fruit Fly Brain Mapped?

    • The process of mapping Fruit Flies (Drosophila melanogaster) brain began in 2013.
    • Scientists dunked the brain of an adult fruit fly in a chemical bath, hardening it into a solid block.
    • This process involved 7,050 sections of the brain and produced 21 million photos to map the entire brain.
    • The first high-resolution image of the brain was created more than a decade after the work started.

    Key findings

    • Scientists identified more than 50 million connections between 139,000 neurons (brain nerve cells).
    • They classified the cells into 8,453 distinct types, making it the largest catalogue of cell types in any brain.
    • The research gave insights into how different types of cells function and how the fruit fly’s eyes process motion and color.
    • A group of “hub neurons” was discovered, which may help speed up information flow.

    Significance of the Work

    • Although the human brain is more complex, the logic of how neurons communicate is similar between fruit flies and humans.
    • Fruit flies are a valuable model system for neuroscience. Their brains solve many of the same problems that human brains do.
    • It could help in understanding and treat mental health conditions like Parkinson’s and depression.
    • The mapping of the fruit fly’s brain raises hopes that scientists will eventually be able to map the entire human brain.

    What are Psychedelic Drugs?

    Mains Paper 3: GS3-17.Awareness in the fields of IT, Space, Computers, Robotics, Nano-technology, Bio-technology and issues relating to Intellectual Property Rights.

    From UPSC perspective, the following things are important:

    Prelims level: Psychedelic Drugs

    Why in the News?

    Researchers from the Tata Institute of Fundamental Research (TIFR) in collaboration with researchers from Cornell, Yale, and Columbia has uncovered how a psychedelic drug interacts with the brain to alleviate anxiety.

    About Psychedelic Drugs

    • Psychedelic drugs are a class of psychoactive substances that alter perception, mood, and cognitive processes. 
    • These drugs often induce hallucinations, altered states of consciousness, and enhanced sensory experiences.
    • They are typically associated with spiritual experiences and have historically been linked with counterculture movements, but they are now being studied for their potential in medical therapies.
    • Examples of Psychedelic Drugs:
      • LSD (Lysergic acid diethylamide): Known for causing intense visual hallucinations and altering thoughts, it is one of the most potent psychedelics.
      • Psilocybin: The active compound found in magic mushrooms, known for creating visual and auditory hallucinations, as well as a deep sense of connection to the environment.
      • MDMA (3,4-methylenedioxymethamphetamine): Often associated with recreational use, but is also being researched for its therapeutic potential, especially in treating PTSD.
      • DMT (Dimethyltryptamine): Produces powerful, short-lived hallucinatory experiences, sometimes referred to as the “spirit molecule.”
      • Mescaline: Found in the peyote cactus, mescaline induces hallucinations and altered states of reality.

    How do they work?

    Psychedelics primarily affect the brain by interacting with the serotonin system, a network of neurotransmitters involved in regulating mood, perception, and cognition.

    • Serotonin Receptors: Psychedelics like LSD and psilocybin bind to 5-HT2A receptors, a type of serotonin receptor. This interaction leads to altered perception, enhanced mood, and hallucinations.
    • Brain Connectivity: They increase communication between different regions of the brain, breaking down normal patterns of activity. This leads to heightened creativity, altered sensory experiences, and a sense of connectedness.

    How Psychedelics hold promise for treating Anxiety and Depression?

    • Resetting Neural Circuits: Psychedelics may “reset” dysfunctional brain circuits, helping treat mood disorders.
    • Reduced Anxiety: They reduce overthinking by dampening activity in the brain’s default mode network.
    • Emotional Release: Patients experience emotional breakthroughs during psychedelic therapy sessions.
    • Neuroplasticity: Psychedelics may promote adaptive brain connections, aiding in recovery from chronic stress and depression.
