    What are ‘Planetary Boundaries’?

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

    Why in the News?

    The Planetary Health Check (PHC) 2025 has warned that 7 of 9 planetary boundaries have now been breached.

    About Planetary Health Check (PHC):

    • The PHC is a global scientific assessment of Earth system health, tracking ecological thresholds that keep the planet habitable.
    • The 2025 report warns that 7 of 9 planetary boundaries have now been breached, with ocean acidification crossing the safe zone for the first time.
    • It highlights how human activities — fossil fuel combustion, deforestation, unsustainable agriculture, and industrial waste — are driving Earth beyond its safe operating space for the first time in 11,000 years.

    What are ‘Planetary Boundaries’?

    What are Planetary Boundaries?

    • Proposition: Coined in 2009 by scientists led by Johan Rockstrom.
    • What are they: Defines safe operating space for humanity by setting ecological thresholds that regulate Earth system stability and resilience.
    • Basis: Based on Holocene conditions (last ~11,000 years) that enabled human civilisation to thrive.
    • Significance: Crossing boundaries risks irreversible environmental collapse.

    • Nine Planetary Boundaries (PBs):

      1. Climate Change (CO₂ Concentration & Radiative Forcing): Safe atmospheric Carbon Dioxide (CO₂) level: 350 parts per million (ppm). Current: 423 ppm (2025); radiative forcing at +2.97 Watts per square meter (W/m²) (safe: +1.5 W/m²).
      2. Biosphere Integrity (Biodiversity Loss / Extinction Rate): Extinction rate at 100 extinctions per million species years (E/MSY) vs safe 10 E/MSY; severe biodiversity decline continues.
      3. Land System Change (Deforestation / Ecosystem Conversion): Global forest cover reduced to 59% (safe: 75%). All major terrestrial biomes breached.
      4. Freshwater Change (Streamflow & Soil Moisture Deviations): Over 20% of global land shows significant streamflow (22.6%) and soil moisture (22%) deviations beyond thresholds. Indo-Gangetic Plain & North China basins most at risk.
      5. Biogeochemical Flows (Nitrogen & Phosphorus Cycles): Excessive use of Nitrogen (N) and Phosphorus (P) in agriculture, worsening dead zones and eutrophication in water bodies.
      6. Novel Entities (Synthetic Pollutants & Plastics): Release of plastics, synthetic chemicals, and untested compounds exceeds the safe zero-threshold for environmental introduction.
      7. Ocean Acidification (Aragonite Saturation State): Surface ocean acidity has increased by 30–40% since the industrial era. Aragonite saturation state (Aragonite) at 2.84 (safe: 2.86). Threatens corals, molluscs, and plankton.
      8. Atmospheric Aerosol Loading (Aerosol Optical Depth – AOD) [Currently Safe]: Interhemispheric Aerosol Optical Depth (AOD) difference: 0.063, below safe threshold 0.10. Still harmful for health despite planetary stability.
      9. Stratospheric Ozone Depletion (Ozone Concentration in Dobson Units – DU) [Currently Safe]: Global ozone concentration stable at 285–286 Dobson Units (DU) (safe: 277 DU). Ozone hole recovery continues, though new threats flagged from rocket launches and satellite debris.
    [UPSC 2018] The term “sixth mass extinction/sixth extinction” is often mentioned in the news in the context of the discussion of:

    (a) Widespread monoculture practices in agriculture and large-scale commercial farming with indiscriminate use of chemicals.

    (b) Fears of a possible collision of a meteorite with the Earth.

    (c) Large scale cultivation of genetically modified crops.

    (d) Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change.

    Desert Soilification Technology

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

    Why in the News?

    For the first time, researchers at the Central University of Rajasthan (CUoR) have successfully grown wheat in arid land of western Rajasthan using desert soilification technology.

    What is Desert Soilification Technology?

    • Overview: It is an innovative biotechnological method that transforms barren desert sand into soil-like material capable of supporting agriculture.
    • Technology: It uses bioformulations and polymers to bind loose sand particles, improve soil texture, and enable water retention.
    • Utility: It is designed to combat desertification, enhance agricultural productivity in arid zones, and ensure sustainable land use.
    • How does it work?
      • Polymer-based Bioformulation: Natural polymers and microbial formulations are applied to desert sand.
      • Cross-Linking of Sand Particles: Bio-polymers create a structural network, binding sand grains together into a soil-like matrix.
      • Water Retention: The cross-linked structure traps water, drastically reducing irrigation needs and preventing rapid percolation of water through sandy soil.
      • Microbial Boost: Introduced beneficial microbes stimulate plant growth, improve soil fertility, and enhance stress resistance of crops.
      • Soil-like Properties: The modified sand mimics fertile soil — enabling nutrient retention, microbial colonization, and sustainable cropping.

    Key Features:

    • Sand-to-Soil Conversion: Cross-links sand particles into a soil-like structure, creating porosity and root-holding capacity.
    • Water Retention Efficiency: Increases moisture-holding ability of sand, thereby reducing irrigation requirements by 30–40%.
    • Microbial Boost: Bioformulation stimulates beneficial soil microbes, enhancing nutrient cycling and crop stress resistance.
    • Crop Versatility: Tested successfully with wheat, bajra, guar gum, chickpea, and is now being expanded to millets and green gram.
    • Low Input Agriculture: Reduces number of irrigation cycles (3–4 vs 5–6 in normal wheat farming).
    • Climate Resilience: Provides a sustainable model for food production in water-stressed and desertified regions.
    • Scalability: Can be replicated in other arid ecosystems beyond Rajasthan (potential use in Middle East, Africa).
    [UPSC 2023] Which one of the following best describes the concept of ‘Small Farmer Large Field’?

    (a) Resettling war-displaced people on shared cultivable land

    (b) Marginal farmers group to coordinate farm operations *

    Why in the News?

    The Bureau of Energy Efficiency (BEE) under the Ministry of Power has issued draft CAFE-3 and CAFE-4 norms, applicable from April 2027 to March 2037.

    About Corporate Average Fuel Efficiency (CAFE) Norms:

    • What is it: Standards that mandate automakers to maintain a sales-weighted fleet average of fuel efficiency and CO₂ emissions across all passenger vehicles.
    • Origin:
      • First introduced in the United States in 1975 after the Arab Oil Embargo, aimed at lowering oil dependency.
      • In India, first notified in 2017 under the Energy Conservation Act, 2001, framed by the Bureau of Energy Efficiency (BEE), Ministry of Power.
    • Objective:
      • Reduce CO₂ emissions and oil imports, improve energy security.
      • Push adoption of EVs, hybrids, flex-fuels, and fuel-efficient technologies.
    • Applicability: Passenger vehicles (< 3,500 kg gross vehicle weight) across petrol, diesel, LPG, CNG, hybrid, and electric categories.
    • Phased Implementation in India:
      • CAFE I (2017–2022) → CO₂ emission limit of 130 g/km.
      • CAFE II (2022–2027) → stricter limit of 113 g/km.
      • CAFE III (Draft, 2027–2032) → 91.7 g/km CO₂ limit, aligned with WLTP (World Harmonised Light Vehicle Test Procedure).
      • CAFE IV (Draft, 2032–2037) → 70 g/km CO₂ limit (most stringent stage yet).
    • Recent Updates (Draft CAFE-3 & CAFE-4, Sept 2025):
      • Automakers allowed to form pools of up to 3 manufacturers.
      • Pooling treated as one fleet for compliance; pool manager bears penalty if limits breached.
      • A manufacturer can join only one pool per year but can switch in later years.
      • Special relief for small cars (under 4m, <909 kg, <1200 cc): eligible for up to 9 g/km CO₂ relief.
      • Incentives for flex-fuel vehicles (ethanol-petrol blends) and strong hybrids alongside EVs.
      • Aim: Balance decarbonisation with consumer affordability and revive the small car segment (which saw 71% sales decline in 6 years).
    • Compliance & Penalties:
      • Exceeding CO₂ limits: Regulatory fines under the Energy Conservation Act, 2001.
      • CAFE credits may be earned, traded, or carried forward to offset temporary lapses.
    • Green Impact:
      • Complements India’s Net Zero 2070 goals.
      • Encourages fuel-efficient models, biofuels, and EV adoption.

    How are CAFE Norms different from Bharat Stage (BS) Norms?
