    2. Giant World of Fungi Beneath Our Feet

      Why in News?

      A study published in the journal Science produced the first global map of arbuscular mycorrhizal (AM) fungi, revealing the enormous extent of underground fungal networks and their importance for climate regulation.

      Key Findings

      • Topsoils worldwide contain about 110 quadrillion km of fungal hyphae.
      • This distance is equivalent to nearly one billion trips between the Earth and the Sun.
      • AM fungal networks store around 300 million tonnes of carbon.
      • This is 4 to 6 times the weight of the entire human population.
      • The study analysed data from more than 16,000 soil cores using machine-learning techniques.

      Role in Climate Regulation

      • AM fungi form symbiotic associations with nearly 70% of all plant species.
      • They exchange Nutrients and water with plants, in return for carbon compounds produced through photosynthesis.
      • These networks sequester approximately 4 billion tonnes of CO₂-equivalent annually.
      • This equals roughly 11% of global human-related carbon emissions.

      Arbuscular Mycorrhizal (AM) Fungi

      • A group of fungi belonging to the phylum Glomeromycota.
      • They colonise plant roots and form mycorrhizae (fungus-root associations).
      • The fungal filaments, called hyphae, extend into the soil and improve nutrient uptake.

      Benefits

      • Enhance absorption of: Phosphorus, Nitrogen, Micronutrients, and Water.
      • Improve plant growth and drought tolerance.
      • Increase soil aggregation and fertility.
      • Contribute to long-term carbon storage.

      Biodiversity Hotspots Identified

      The study found that around 40% of global AM fungal networks occur in grassland ecosystems, including South Sudan, The Tibetan Plateau, and Banni Grasslands.

      Major Threats

      • Croplands contain about 50% lower fungal density compared to natural ecosystems.
      • Grasslands are being converted into agricultural land four times faster than forests.
      • This threatens underground fungal biodiversity and its ecosystem services.

      Why is the Study Important?

      • Highlights fungi as a form of “living infrastructure” supporting ecosystems.
      • Emphasises the need to include soil biodiversity and fungi in climate policy.
      • Strengthens the case for grassland conservation alongside forest protection.

    6. Long overdue: On coal exchanges 

      Why in the News?

      India has unveiled the Coal Exchange Rules, 2026, marking a major structural reform in the coal sector. For the first time, coal will be traded through regulated exchange platforms similar to power exchanges

      What are the Coal Exchange Rules, 2026?

      The Coal Exchange Rules, 2026, notified by the Ministry of Coal, establish a legally binding framework for transparent, electronic “many-to-many” spot mineral trading. Regulated by the Coal Controller Organisation, the rules aim to improve price discovery and market access for consumers.

      Key Features of the Rules

      1. Electronic Trading: The system transitions coal marketing from the traditional “one-to-many” bilateral model to an efficient, competitive digital trading platform where multiple buyers and sellers can transact.
      2. Mandatory Physical Delivery: All transactions must culminate in physical delivery of the coal. These are supported by independent quality verification to ensure contractual compliance.
      3. Regulatory Oversight: The Coal Controller Organisation acts as the central market regulator, handling the registration, supervision, and auditing of exchanges, as well as enforcing safeguards against market manipulation.
      4. Registration Validity: Eligible entities (incorporated as companies under the Companies Act, 2013) are granted authorizations to establish and operate exchanges for 25 years.
      5. Financial Obligations: Operators pay a ₹50 Lakh one-time registration fee, a ₹3 Lakh application fee, and an annual fee calculated as either ₹30 Lakh or 0.02% of the total trading volume, capped at ₹5 Crore.

      How can coal exchanges transform India’s coal market structure?

      1. Market-Based Trading: Establishes regulated platforms for buying and selling coal through transparent mechanisms.
      2. Price Discovery: Creates market-driven price signals instead of relying primarily on bilateral negotiations.
      3. Transparency: Reduces opacity associated with traditional contractual arrangements.
      4. Competition: Enables broader participation by producers and consumers.
      5. Secondary Markets: Facilitates development of coal trading beyond primary allocation channels.

      Why is the existing coal allocation mechanism considered inadequate?

      1. Long-Term Contracts: Most coal transactions currently occur through long-duration agreements, particularly for the power sector.
      2. Auction Dependence: Significant volumes are allocated through auctions where prices may rise substantially.
      3. Coal India Dominance: Non-regulated consumers often depend on Coal India auctions.
      4. Premium Pricing: Coal is frequently sold at premiums to the highest bidder.
      5. Limited Market Signals: Existing mechanisms provide inadequate real-time information regarding shortages and surpluses.

      What lessons can be drawn from India’s power exchange experience?

      1. Market Signalling: Power exchanges evolved into indicators of scarcity and surplus conditions.
      2. Balancing Function: Initially addressed short-term shortages before becoming broader market institutions.
      3. Reference Prices: Spot prices emerged as benchmarks for the wider power market.
      4. Enhanced Efficiency: Improved resource allocation without replacing long-term Power Purchase Agreements (PPAs).
      5. System Stress Indicator: Exchange prices increasingly reflected grid conditions and demand-supply imbalances.

      Can coal exchanges help balance regional shortages and surpluses?

      1. Inventory Utilisation: Enables idle or surplus coal stocks to be traded efficiently.
      2. Regional Balancing: Allows coal-deficit regions to access supplies from surplus areas.
      3. Supply Optimization: Improves allocation without requiring additional production.
      4. Resource Efficiency: Maximizes utilization of existing inventories.
      5. Market Liquidity: Encourages continuous trading and availability.

      What challenges could limit the success of coal exchanges?

      1. Quality Variation: Coal quality differs significantly across grades and mines.
      2. Non-Fungibility: Unlike electricity, coal is not a uniform commodity.
      3. Standardisation Requirement: Requires robust quality certification mechanisms.
      4. Contract Enforcement: Strong dispute resolution and enforcement systems are necessary.
      5. Liquidity Constraints: Exchanges require adequate trading volume to remain viable.

      What logistical challenges could constrain coal exchanges?

      1. Railway Dependence: Coal transportation relies heavily on railway infrastructure.
      2. Last-Mile Connectivity: Mine-to-consumer logistics remain uneven across regions.
      3. Freight Costs: Transportation costs can significantly influence final coal prices.
      4. Delivery Delays: Physical delivery constraints may reduce exchange efficiency.
      5. Infrastructure Gaps: Inadequate evacuation infrastructure may limit market integration.

      2. Liquidity Creation: Encourages active participation by consumers.
      3. Price Benchmarking: Helps establish credible market reference prices.
      4. Supply Assurance: Supports reliability of exchange operations.
      5. Institutional Confidence: Enhances acceptance of the platform.

      Why should retail and smaller consumers be integrated into coal exchanges?

      1. Accessibility: Expands coal access beyond large industrial consumers.
      2. Competition: Reduces concentration of market power.
      3. Inclusiveness: Facilitates participation of smaller industries.
      4. Price Transparency: Provides equal access to market information.
      5. Market Expansion: Increases overall trading activity.

      What institutional safeguards are required for successful implementation?

      1. Volatility Management: Ensures protection against excessive price fluctuations.
      2. Dispute Resolution: Provides mechanisms for conflict settlement.
      3. Logistics Integration: Strengthens transportation and delivery systems.
      4. Regulatory Oversight: Ensures compliance and market integrity.
      5. Settlement Systems: Facilitates efficient trading and delivery.

      Conclusion

      The Coal Exchange Rules, 2026 represent a shift from administrative allocation towards market-based coal governance. Their success will depend on quality standardisation, liquidity creation, Coal India’s participation, efficient logistics, and strong regulatory oversight. If implemented effectively, coal exchanges can become an important mechanism for balancing regional shortages, improving transparency, and strengthening India’s energy security.
