    CEC Recommends Restoring Original ESZ Around Bannerghatta National Park

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Why in the News?

    In January 2026, the Central Empowered Committee (CEC) recommended restoring the original 2016 Ecologically Sensitive Zone (ESZ) around Bannerghatta National Park, reversing the reduced ESZ notified in 2020.

    About Bannerghatta National Park (BNP)

    • A protected wildlife reserve and biodiversity hotspot
    • Acts as the southern green lung of Bengaluru
    • Crucial for conserving forests, elephants, and wildlife corridors
    • Located in the Anekal hill range, Karnataka

    Geological and Physical Features

    • Granite hill ranges: Ancient granite formations of the Anekal Hills
    • Moist deciduous valleys: Support elephants, deer and predators
    • Dry scrub uplands: Important grazing habitats
    • Wildlife corridors: Links BR Hills and Sathyamangalam forests, forming a key elephant corridor
    • Water system: Suvarnamukhi stream flows through the park, sustaining wildlife

    What is the ESZ Issue

    • 2016 draft ESZ: 268.9 sq km
    • 2020 notification: Reduced to 168.64 sq km
    • Reduction excluded:
      • Key elephant corridors
      • Critical forest buffer zones
    • Resulted in increased pressure from:

  • Nuclear Energy

    Greenwald Limit in Fusion Research

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Why in the News?

    China’s Experimental Advanced Superconducting Tokamak (EAST) fusion reactor has achieved stable plasma densities 30 to 65 percent higher than the Greenwald limit, overcoming a decades old constraint in nuclear fusion research.

    About Greenwald Limit

    • The Greenwald limit is a theoretical upper limit on plasma density in a tokamak fusion reactor.
    • It links the maximum stable plasma density to:
      • Plasma current
      • Size of the tokamak
    • Crossing this limit usually causes plasma instability and sudden collapse.

    Why the Greenwald Limit Matters?

    • Nuclear fusion requires:
      • Very high temperature
      • High plasma density
      • Sufficient confinement time
    • The Greenwald limit restricted how much fuel plasma could be packed into a tokamak.
    • It has been a major bottleneck to achieving self sustaining fusion or ignition.

    Prelims Pointers

    • Greenwald limit applies to tokamak fusion reactors
    • Exceeding it traditionally causes plasma instability
    • EAST achieved stable plasma beyond this limit
    • Breakthrough achieved by plasma wall interaction control
    • Important for progress towards fusion ignition and clean energy
    [2016] India is an important member of the ‘International Thermonuclear Experimental Reactor’. If this experiment succeeds, what is the immediate advantage for India? 

    (a) It can use thorium in place of uranium for power generation

    (b) It attains a global role in satellite-navigation

    (c) It can drastically improve the efficiency of its fission reactors in power generation

    (d) It can build fusion reactors for power generation

  • Air Pollution

    Air Pollution Aerosols Intensify and Prolong Winter Fog Over North India: IIT Madras Study

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    Why in the News

    A Indian Institute of Technology Madras led study published in Science Advances shows that air pollution aerosols are making winter fog over north India denser and longer lasting, worsening visibility and health impacts.

    About Aerosols

    • Aerosols are tiny solid or liquid particles suspended in the atmosphere.
    • They strongly influence air quality, weather and climate.
    • Natural sources: desert dust, sea spray, volcanic ash, forest fires
    • Human sources: vehicle emissions, industrial pollution, biomass burning, coal and diesel use
    • Primary aerosols are emitted directly.
    • Secondary aerosols form in the air from gases like sulphur dioxide and nitrogen oxides.

    Key Features

    • Extremely small size: penetrate deep into lungs and remain airborne easily
    • Persistence: stay suspended for days to weeks, travel long distances
    • Condensation nuclei: provide surfaces for water vapour to condense, aiding fog and cloud formation
    • Radiative effects:
      • Scatter sunlight: reflective aerosols cool the surface
      • Absorb heat: black carbon warms the atmosphere

    How Aerosols Affect Winter Fog

    • Increase number of fog droplets, making fog thicker
    • Reduce sunlight reaching the surface, causing cooling that sustains fog
    • Slow fog dissipation, leading to prolonged low visibility episodes

    Prelims Pointers

    • Aerosols act as condensation nuclei for fog and clouds
    • Black carbon absorbs heat while sulphate aerosols reflect sunlight
    • Human sources significantly amplify winter fog over north India
    • Aerosols influence health, visibility, weather and climate simultaneously
    [2019] In the context of which of the following do some scientists suggest the use of cirrus cloud thinning technique and the injection of sulphate aerosol into stratosphere? 

    (a) Creating the artificial rains in some regions 

    (b) Reducing the frequency and intensity of tropical cyclones 

    (c) Reducing the adverse effects of solar wind on the Earth 

    (d) Reducing the global warming

  • ISRO Missions and Discoveries

    PSLV-C62 Mission Failure

    Prelims Only | Science Tech | Mains Paper 3: Achievements Of Indians In S&T

    Why in the News

    The Indian Space Research Organisation’s first launch of 2026, the PSLV-C62 mission, failed to place 16 satellites into the intended orbit on 12 January 2026. This marks the second consecutive failure of the Polar Satellite Launch Vehicle (PSLV), ISRO’s most reliable launch vehicle for over three decades.

    About PSLV-C62 Mission

    • Launch Vehicle: Polar Satellite Launch Vehicle
    • Payload: 16 satellites
      • Includes 7 foreign satellites
    • Mission outcome: Failed to reach intended orbit
    • Failure stage: Third stage (after successful completion of first two stages)

    Why the Failure Matters

    • PSLV is known as ISRO’s workhorse, with a long record of success since the 1990s.
    • This is the second straight PSLV failure, the first occurring in May 2025.
    • Consecutive failures raise concerns about reliability in the third stage, a critical phase of orbital insertion.

    Possible Cause of Failure

    • Exact cause not yet identified.
    • Based on the May 2025 failure, issues may relate to:
      • Drop in combustion chamber pressure in the third stage motor
      • Reduced thrust leads to insufficient acceleration needed to stabilise orbit
    • The Failure Analysis Committee report of the previous mission has not been made public.

    Why the Third Stage is Critical

    • The third stage provides high acceleration required to:
      • Maintain orbital velocity
      • Prevent premature orbital decay
    • Any pressure or thrust instability at this stage directly impacts mission success.

    PSLV: Four-Stage Configuration (Prelims Focus)

    1. First Stage
      • Solid propellant
      • Provides lift-off and overcomes gravity and atmospheric drag
      • Carries rocket to ~50–60 km altitude
    2. Second Stage
      • Liquid propellant
      • Improves velocity and stabilisation
    3. Third Stage
      • Solid motor
      • Provides rapid acceleration for orbital insertion
      • Most failure-prone stage in recent missions
    4. Fourth Stage
      • Liquid engines
      • Fine-tunes orbit and deploys satellites

    Prelims Pointers

    • PSLV is a four-stage launch vehicle.
    • Recent PSLV failures occurred during the third stage.
    • Combustion chamber pressure is critical for orbital velocity.
    • PSLV has been operational for over 30 years.
    • ISRO has not yet released the Failure Analysis Committee report for the 2025 failure.
    [2018] With reference to India’s satellite launch vehicles, consider the following statements: 

    1. PSLVs launch the satellites useful for Earth resources monitoring whereas GSLVs are designed mainly to launch communication satellites

    2. Satellites launched by PSLV appear to remain permanently fixed in the same position in the sky, as viewed from a particular location on Earth

    3. GSLV Mk III is a four-stage launch vehicle with the first and third stages using solid rocket motors, and the second and fourth stages using liquid rocket engines.
