    India Among Four Nations Driving Global Pesticide Toxicity

    Why in the News

    A new study published in Science finds that India is among four countries contributing nearly 70 percent of the world’s Total Applied Toxicity (TAT) from agricultural pesticides. Experts have also raised concerns that the proposed Pesticides Management Bill 2025 may weaken safeguards compared to the older law.

    What is Total Applied Toxicity (TAT)?

    • TAT measures not just the quantity of pesticides used, but their toxicity and lethality to non target species.
    • Researchers analysed over 600 pesticides across 65 countries from 2013 to 2019.
    • Global TAT has increased, especially for around 20 commonly used agricultural pesticides.

    Countries Driving Global TAT

    • Four major contributors: China, Brazil, United States, and India
    • Together, they account for nearly 70 percent of global pesticide toxicity.
    • Only Chile is currently on track to meet the UN target of reducing pesticide risk by 50 percent by 2030.

    Impact on Biodiversity

    Species most affected:

    1. Terrestrial arthropods
    2. Soil organisms
    3. Fish
    4. Pollinators
    5. Aquatic plants
    6. Terrestrial vertebrates

    Regions with high increases include sub Saharan Africa and parts of the Indian subcontinent.

    Link to Global Commitments

    • At the 2022 United Nations Biodiversity Conference, countries committed to reducing pesticide risk by 50 percent by 2030. The findings indicate that global progress is not on track.

    Indian Legal Framework

    1. Insecticides Act 1968

    • Focused mainly on agricultural use
    • Limited regulation of domestic and non agricultural applications
    • Considered outdated
    • India reportedly uses several pesticides that are banned in parts of Europe, such as paraquat.

    2. Pesticides Management Bill 2025

    • Proposed to replace the 1968 Act
    • Aims to reduce risk to people and environment
    • Encourages biological and traditional knowledge based alternatives
    • Experts warn that without stronger liability and monitoring provisions, it may not significantly improve regulation
    [2019] In India, the use of carbofuran, methyl parathion, phorate and triazophos is viewed with apprehension. These chemicals are used as: 

    (a) pesticides in agriculture 

    (b) preservatives in processed foods 

    (c) fruit-ripening agents 

    (d) moisturising agents in cosmetics

    [23rd February 2026] The Hindu OpED: Parliament’s historic law; an extended wait for women

    PYQ Relevance

    [UPSC 2019] The reservation of seats for women in the institutions of local self-government has had a limited impact on the patriarchal character of the Indian Political Process.” Comment.Linkage: It provides an analytical foundation to evaluate whether the Constitution (106th Amendment) Act, 2023 for Parliamentary reservation will ensure substantive gender justice or replicate proxy representation seen in Panchayati Raj institutions.

    Mentor’s Comment

    The Nari Shakti Vandan Adhiniyam (Women’s Reservation Act, 2023) was projected as a landmark reform in India’s constitutional history. However, its implementation has been tied to the post-Census delimitation process, effectively postponing operationalisation until at least 2034. The debate raises critical questions of constitutional design, political incentives, federal balance, and institutional accountability. This issue is central to GS Paper II (Polity & Governance) and also intersects with representation, federalism, and social justice.

    Why in the News?

    Parliament passed the Constitution (106th Amendment) Act, 2023 in September 2023, guaranteeing 33% reservation for women in the Lok Sabha and State Assemblies for the first time in independent India’s constitutional history. The earlier Women’s Reservation Bills (1996 onwards) repeatedly lapsed despite Rajya Sabha passage in 2010. The 2023 Act was hailed as a historic correction to India’s low female representation (about 15% in Lok Sabha). However, the Act mandates implementation only after the first Census conducted post-2026 and subsequent delimitation. Given that delimitation may conclude around 2032-33, reservation may operate only from the 2034 general election. The reform therefore represents a constitutional milestone accompanied by an operational deferment.

    What are the key provisions of the Constitution (106th Amendment) Act, 2023?

    1. Reservation Mechanism: One-third (33%) of seats are reserved for women in the Lok Sabha, State Assemblies, and the Legislative Assembly of the National Capital Territory of Delhi.
    2. SC/ST Inclusion: The reservation includes a sub-quota for women from Scheduled Castes (SCs) and Scheduled Tribes (STs) within their respective reserved seat categories.
    3. Effective Date: The quota will take effect after the first census conducted following the Act’s commencement is published and the subsequent delimitation exercise is completed.
    4. Rotation of Seats: Seats reserved for women will be rotated after each delimitation exercise.
    5. Duration: The provision is valid for 15 years from its implementation, with potential for extension by Parliament.

    Constitutional Articles:

    1. Article 330A: Adds reservation for women in the Lok Sabha.
    2. Article 332A: Adds reservation for women in State Assemblies.
    3. Article 334A: Sets the timeline for commencement and expiry (sunset clause). It provides that reservation shall come into effect after delimitation and remain for 15 years (subject to extension).

    Why Has Implementation Been Linked to Census and Delimitation?

    1. Article 82 Requirement: Mandates delimitation after each Census.
    2. Sequential Process: Census to Publication to Delimitation Commission to Redrawing constituencies.
    3. Census Schedule: Next Census to be conducted after 2026 (likely 2027).
    4. Time Lag: Data verification and delimitation historically take 4-6 years.
    5. Outcome: Reservation operational only after delimitation, possibly 2034.

    Does the Delimitation Linkage Reflect Political Incentive Structuring?

    1. Seat Conversion Impact: One-third of 543 Lok Sabha seats (~181 seats) would become women-only if implemented immediately.
    2. Incumbent Displacement: Large-scale replacement of sitting male legislators.
    3. Expansion Strategy: Delimitation may increase total seats to around 800-888, absorbing reservation without eliminating incumbents.
    4. Political Risk Mitigation: Expansion diffuses electoral shock.

    How Does Delimitation Intersect with Federal Balance and Population Politics?

    1. 1976 Freeze: Seat redistribution frozen to protect States that controlled population growth.
    2. Post-2026 Redistribution: High-growth States gain proportional representation.
    3. North-South Tension: Southern States risk relative seat reduction.
    4. Gender Justice Entanglement: Women’s representation linked to unresolved inter-state distribution debate.

    What Design and Implementation Gaps Persist in the Amendment?

    1. Absence of OBC Sub-Quota: No reservation for OBC women despite OBC women forming significant demographic share.
    2. Rotation Mechanism Ambiguity: No clarity on frequency or methodology of constituency rotation.
    3. Upper House Exclusion: No application to Rajya Sabha or Legislative Councils.
    4. Operational Rules Pending: Absence of procedural clarity increases scope for litigation and administrative uncertainty.

    What Are the Governance and Institutional Implications?

    1. Delayed Representation: Constitutional right deferred.
    2. Symbolic vs Substantive Reform: Law passed without immediate enforceability.
    3. Institutional Accountability: Parliament controls amendment pathway for decoupling reservation from delimitation.
    4. Democratic Legitimacy: Extended delay risks weakening reform credibility.

    Conclusion

    The Constitution (106th Amendment) Act, 2023 institutionalises gender parity within legislative representation. However, by linking implementation to future delimitation, it defers substantive equality. Timely operationalisation is essential to align constitutional promise with democratic practice.

  • Freedom of Speech – Defamation, Sedition, etc.

    Protecting the Freedom of speech of MPs

    Why in the News?

    Recent parliamentary sessions witnessed large-scale expunction of remarks made by Opposition leaders, raising concerns over misuse of procedural rules. The issue centres on whether the Speaker (Lok Sabha)/Chairman’s (Rajya Sabha) powers are being used to regulate decorum or to restrict the constitutional freedom of speech of Menmbers of Parliament (MPs) under Article 105.

    Which Parliamentary Privileges Specifically Protect Freedom of Speech of MPs?

    Article 105 of the Constitution guarantees freedom of speech to Members of Parliament (MPs) within the Houses. This privilege enables fearless debate, executive accountability, and institutional balance. 

    1. Freedom of Speech in the House (Article 105(1)): Ensures members speak without fear while Parliament is in session and business is being transacted. This freedom is essential for effective discharge of legislative duties and is distinct from Article 19(1)(a).
    2. Immunity from Court Proceedings (Article 105(2)): Grants complete protection from civil or criminal liability for anything said or any vote given in Parliament or its committees. The term “anything” carries the widest amplitude and covers every statement made during parliamentary business.
    3. Absolute Judicial Non-Interference: Courts lack jurisdiction to question speech made inside the House, even if statements are malicious, false, or amount to contempt of court. Once speech is made during parliamentary proceedings, it is immune from judicial scrutiny.
    4. Protection Against External Investigation: Any investigation outside Parliament into a member’s speech or vote amounts to serious interference with parliamentary privilege. Threatening legal action for statements made in the House constitutes breach of privilege.
    5. Distinct from Article 19(2) Restrictions: Reasonable restrictions applicable to citizens under Article 19(2) do not circumscribe speech inside Parliament. Parliamentary speech enjoys higher constitutional insulation.
    6. Comprehensive Constitutional Code: Clauses (1) and (2) of Article 105 form a complete code regarding speech and immunity. Matters outside this scope, such as defamatory publication of expunged questions, remain subject to ordinary law.
    7. Extension to Non-Members with Speaking Rights: Immunity under Article 105(2) applies to persons constitutionally entitled to speak in Parliament (e.g., Attorney General), ensuring functional continuity of debate.
    8. Internal Regulation by Rules of Procedure: While constitutionally protected, speech remains subject to House rules and presiding officer’s authority. The Chair may act against defamatory, incriminatory, or indecorous statements.
    9. Committee of Privileges Oversight: Emphasises that privilege is not an unrestricted licence. Misuse may cause disproportionate harm, particularly as individuals defamed in Parliament have no right of reply or judicial remedy.
    10. Moral Obligation of Restraint: Members, as public representatives, bear heightened responsibility. Abuse of immunity can undermine citizens’ rights who otherwise rely on courts for protection.

    What Is the Constitutional Philosophy Behind Freedom of Speech in Parliament?

    1. Parliamentary Privilege: Recognised as essential for smooth functioning of Legislature.
    2. Erskine May Doctrine: Identifies freedom of speech as the principal privilege of Parliament.
    3. Functional Necessity: Enables free, frank, and fearless debate.
    4. Executive Accountability: Question Hour and debates ensure government transparency.
    5. Democratic Legitimacy: Parliamentary criticism strengthens governance rather than weakens it.

    Does Expunction of Parliamentary Speeches Undermine Article 105?

    1. Article 105 Protection: Guarantees freedom of speech in Parliament subject only to constitutional limitations, not arbitrary procedural curtailment.
    2. Expunction Power: Rules permit presiding officers to remove unparliamentary, defamatory, indecent, or undignified words, not entire arguments.
    3. Constitutional Supremacy: Rules of procedure cannot override constitutional rights.
    4. Risk of Mindless Application: Excessive deletions may distort legislative record and infringe MPs’ privileges.
    5. Institutional Record: Parliamentary debates are preserved for posterity; arbitrary removal affects historical and legal accountability.

    How Do Parliamentary Rules Balance Decorum and Democratic Debate?

    1. Procedural Regulation: Rules regulate sub judice matters, personal allegations, and defamatory statements.
    2. Legislative Dignity: Ensures debate does not degrade into personal attacks.
    3. Proportionality Principle: Regulation must target specific offensive words, not suppress substantive criticism.
    4. Presiding Officer’s Duty: Ensures decorum while safeguarding members’ constitutional privilege.

    Can Procedural Rules Be Weaponised Against the Opposition?

    1. Political Neutrality Requirement: Presiding officers must function impartially to maintain institutional credibility.
    2. Selective Enforcement Risk: Unequal application of expunction powers erodes trust.
    3. Opposition’s Constitutional Role: Essential for scrutiny of executive actions.
    4. Attempted Disqualification: Parliament lacks power to disqualify members outside the constitutional framework (Articles 102 and 103).
    5. Democratic Breakdown Indicator: Curtailing opposition speech signals weakening of deliberative culture.

    How Does the Government-Opposition Relationship Shape Democratic Stability?

    1. Constructive Opposition: Criticism provides corrective feedback.
    2. Institutional Forbearance: Democratic survival depends on mutual restraint.
    3. Majority-Minority Balance: Majority governs; minority critiques.
    4. Historical Practice: Prime Minister Nehru regularly attended Question Hour and listened to opposition speeches, reinforcing institutional respect.
    5. Erosion Risk: Breakdown of dialogue weakens parliamentary culture.

    What Are the Institutional and Governance Implications?

    1. Accountability Deficit: Restricting debate reduces executive scrutiny.
    2. Transparency Impact: Incomplete records distort public understanding.
    3. Legitimacy Concerns: Perception of bias weakens institutional credibility.
    4. Democratic Norms: Healthy dissent is integral to constitutional morality.
    5. Long-Term Precedent: Expansive interpretation of expunction powers may institutionalise executive dominance.

    Conclusion

    Freedom of speech in Parliament is not merely a privilege of MPs but a safeguard for democracy. Procedural rules must regulate debate without diminishing constitutional guarantees. Sustaining institutional neutrality and respecting dissent are essential to preserving the credibility of India’s parliamentary democracy.

  • Artificial Intelligence (AI) Breakthrough

    AI and the brain: similar in scale, different in design

    Why in the News?

    GPT-4 introduced a new design that activates only selected parts of its system for specific tasks, similar to how the human brain works. At the same time, AI models are now approaching the brain in scale but consume far more energy. This contrast between similar size and very different efficiency has made the AI-brain comparison a major policy and technological issue.

    How does the scale convergence between AI models and the human brain raise governance and infrastructure challenges?

    1. Parameter Expansion: GPT-3 contains 175 billion parameters; newer models approach trillions, nearing the brain’s ~100 trillion synapses. Scale increases computational dependency and infrastructure concentration.
    2. Data Centre Energy Demand: Training and operating large AI models require megawatts of electricity. Ensures rising carbon footprint and grid stress.
    3. Hardware Dependence: AI training relies on high-performance GPUs originally developed for video gaming. Strengthens semiconductor concentration risks.
    4. Digital Infrastructure Concentration: Massive parallel computation requires clustered data centres. Facilitates market dominance by few global technology firms.
    5. Strategic Autonomy Concern: Nations lacking advanced chip fabrication capacity face technological dependence. Impacts India’s semiconductor mission and AI self-reliance goals.

    In what ways does mixture-of-experts architecture influence regulatory and accountability frameworks?

    Mixture-of-Experts (MoE) is a type of Artificial Intelligence model design where: instead of using the entire neural network for every task and the system activates only a few specialised parts (“experts”) for each input.

    1. Selective Activation: GPT-4 activates specialised network portions for specific tasks. Enhances computational efficiency but complicates traceability
    2. Modular Processing: Resembles the brain’s region-specific activation (language, vision, movement). Raises issues of explainability in AI outputs.
    3. Sparse Routing Mechanism: Routes input through selected pathways rather than full network. Challenges transparency audits.
    4. Task-Based Resource Allocation: Adjusts computational effort based on difficulty. Requires regulatory standards for algorithmic accountability.
    5. Governance Implication: Fragmented internal processing complicates liability assignment in AI-generated harms.

    Why does energy efficiency disparity between AI and the human brain matter for sustainability policy?

    1. Metabolic Efficiency: Human brain operates at ~20 watts of power. Demonstrates biological optimisation.
    2. Event-Driven Signalling: Biological neurons activate selectively and sparsely. Conserves energy.
    3. Digital Arithmetic Dependence: AI systems perform continuous high-precision computation. Increases electricity consumption.
    4. Carbon Footprint Risk: Large-scale AI training elevates emissions through energy-intensive data centres.
    5. Green AI Imperative: Necessitates energy-efficient chip design, including neuromorphic hardware and spike-like operations.

    How do differences in feedback mechanisms and learning processes impact ethical and institutional oversight?

    1. Deep Feedback Loops: Brain processes signals forward, backward, and laterally. Enables contextual interpretation.
    2. Contextual Meaning Formation: Human cognition integrates prior knowledge. Reduces rigid output behaviour.
    3. Feed-Forward Architecture: Most LLMs rely on stacked layers without true recurrence. Limits adaptive contextual reasoning.
    4. Statistical Learning Model: AI identifies probabilistic patterns from text corpora. Does not “understand” meaning intrinsically.
    5. Regulatory Concern: Absence of embodied cognition raises risks of hallucinations, misinformation, and biased outputs.

    What are the implications of AI’s divergence from biological intelligence for public policy and strategic planning?

    1. Non-Biological Scaling: Machines are not constrained by evolutionary limits. Enables rapid parameter expansion.
    2. Super-Computational Potential: AI may surpass humans in speed and pattern recognition.
    3. Efficiency Trade-off: AI sacrifices energy efficiency for computational speed.
    4. Neuromorphic Research: Attempts to mimic spike-based operations to reduce power usage.
    5. Policy Imperative: Requires anticipatory regulation balancing innovation and risk mitigation.

    How does AI’s hardware dependency influence economic concentration and digital sovereignty?

    1. GPU Dominance: AI training dependent on limited global chip manufacturers.
    2. Capital Intensity: High infrastructure cost restricts entry to large corporations.
    3. Data Concentration: Models trained on massive datasets inaccessible to smaller players.
    4. Regulatory Challenge: Ensures competition law scrutiny in AI markets.
    5. National Security Dimension: AI capability linked to defence, cyber security, and economic competitiveness.

    Conclusion 

    AI is approaching the human brain in scale but remains fundamentally different in design and efficiency. While the brain operates with minimal energy and deep contextual feedback, AI depends on massive computation and data infrastructure.

    The key policy challenge lies in balancing innovation with sustainability, accountability, and digital sovereignty. Future AI development must focus not just on scale, but on efficiency, transparency, and alignment with human values.

  • Why Does Wildfire Smoke Swirl Only One Way?

    Why in the News

    Two recent studies published in Weather and Climate Dynamics and presented at the American Meteorological Society meeting explain why wildfire smoke in the stratosphere forms spinning bubbles that rotate in only one direction depending on the hemisphere.

    What Is Observed?

    • After intense wildfires, smoke can rise high into the stratosphere. Instead of dispersing immediately, it sometimes forms a compact spinning bubble called a smoke vortex.
      • Clockwise in the Northern Hemisphere
      • Counterclockwise in the Southern Hemisphere

    Why Does It Rotate Only One Way?

    • Smoke Heats the Surrounding Air: Smoke particles absorb sunlight. This warms the air around them. Warm air becomes buoyant and rises. This upward movement creates a vertical column of heated air.
    • Earth’s Rotation Effect: Because Earth rotates, moving air experiences a deflection known as the Coriolis effect
      • In the Northern Hemisphere, air is deflected to the right. In the Southern Hemisphere, air is deflected to the left. As the heated smoke rises, Earth’s rotation causes it to spin in a preferred direction.

    Why the Bubble Persists

    • The rotating vortex traps warm smoke near its centre. Reduces mixing with surrounding air.
    • Helps the bubble rise higher into the stratosphere. This mechanism is similar to how cyclones maintain structure, but on a smaller and smoke driven scale.
    [2024] With reference to “Coriolis force,” which of the following statements is/are correct? 1. It increases with increase in wind velocity. 

    2. It is maximum at the poles and is absent at the equator.

  • Proteins Tweaked as Quantum Sensors Inside the Body

    Why in the News

    Two recent studies published in Nature in February 2026 have demonstrated that fluorescent proteins can be genetically engineered to function as quantum sensors inside living cells, detecting magnetic fields and radio waves.

    Background

    • The discovery of Green Fluorescent Protein revolutionised biology by allowing scientists to visualise cellular processes. This breakthrough was recognised with the Nobel Prize in Chemistry in 2008.
    • Now, researchers have shown that such proteins can be modified to detect quantum level signals inside cells.

    Core Scientific Principle

    When a fluorescent protein absorbs light:

    1. An electron moves to a higher energy state.
    2. It usually returns, emitting light.
    3. In some cases, a radical pair forms with unpaired electrons.
    4. Their spin states are influenced by weak magnetic fields.
    5. Changes in spin alter fluorescence intensity.

    This is known as optically detected magnetic resonance, a quantum phenomenon.

    Key Research Findings

    1. Enhanced Yellow Fluorescent Protein

    • Exhibits a metastable triplet state
    • Spin state controlled using laser pulses and microwaves
    • Demonstrated qubit like behaviour inside cells
    • Observed in human kidney cells and in Escherichia coli at room temperature

    2. MagLOV Proteins

    • Engineered from plant light sensing proteins
    • Magneto sensitive fluorescent variants
