Why in the News?

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel Devoret, and John Martinis for their discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.

nobel

Discovery of Macroscopic Quantum Effects:

  • Essence of the Discovery: John Clarke, Michel Devoret, and John Martinis proved that quantum effects—tunnelling and energy quantisation—can occur in macroscopic electrical circuits, not just in atoms or particles.
  • Experiments (UC Berkeley, 1984–85): Demonstrated that superconducting circuits, visible to the naked eye, act as quantum systems when isolated from external disturbances.
  • Observed Phenomena:
    • Macroscopic Quantum Tunnelling: Electric current “jumps” through an insulating barrier even when classical physics predicts no flow.
    • Energy Quantisation: The circuit holds only discrete energy levels, behaving like an artificial atom that exchanges energy in fixed quanta.
  • Scientific Breakthrough: First experimental proof that quantum mechanics governs engineered large-scale systems, forming the foundation of quantum computing.

The Josephson Junction:

  • Structure: Two superconductors separated by a thin insulating layer, allowing the passage of Cooper pairs paired electrons that move as a single quantum entity.
  • Mechanism: Though insulators block current in classical systems, Cooper pairs tunnel through the barrier, producing a supercurrent without resistance.
  • Key Berkeley Findings:
    • The phase difference across the junction behaved as a quantum variable, showing discrete energy states.
    • Spontaneous tunnelling of current produced measurable voltage, confirming macroscopic quantum tunnelling.
  • Outcome: The Josephson junction became the first laboratory model of macroscopic quantum behaviour and the prototype for superconducting qubits used in today’s quantum computers.

Significance:

  • Redefined Quantum Boundaries: Established that quantum laws are universal, applying from electrons to circuits of billions of atoms when quantum coherence is preserved.
  • Foundation for Quantum Computing: Provided the conceptual basis for superconducting qubits, now central to Google, IBM, and TIFR quantum processors.
  • Technological Impact: Enabled innovations in quantum sensors, precision metrology, and quantum communication through microwave-to-optical conversion.
  • Philosophical Insight: Resolved the scale question of how large a system can remain quantum,  proving that superconducting isolation preserves coherence even at macroscopic levels.
  • Legacy: Bridged the quantum–classical divide, converting a theoretical boundary into experimentally verified reality, launching the modern quantum technology era.
[UPSC 2022] Which one of the following is the context in which the term “qubit” is mentioned?

Judicial Reforms

[7th October 2025 ] The Hindu Op-ed: Calling out the criticism of the Indian Judiciary

PYQ Relevance

[UPSC 2023] Constitutionally guaranteed judicial independence is a prerequisite of democracy”. Comment.

Linkage: The article defends judicial independence as the backbone of India’s democracy, arguing that blaming courts for developmental delays undermines their constitutional role as checks on executive excesses. It reinforces that true democracy thrives only when judicial autonomy remains uncompromised.

Mentor’s Comment

In an era where the pursuit of Viksit Bharat (Developed India) dominates public discourse, the judiciary is increasingly being portrayed as a bottleneck in India’s development journey. However, this narrative is not only simplistic but dangerous. This article delves deep into the recent criticism of India’s judiciary, particularly remarks made by Sanjeev Sanyal, and explores whether such allegations hold ground. It highlights how governance failures, legislative vagueness, and unchecked executive litigation are often the real culprits behind systemic inefficiencies. The aim is to help aspirants understand the complex interlinkages between judiciary, governance, and development, a recurring UPSC theme.

Introduction

The judiciary has long been one of the cornerstones of India’s democracy. Yet, it often finds itself under scrutiny for delays, pendency, and procedural rigidities. The recent remarks by Sanjeev Sanyal, member of the Prime Minister’s Economic Advisory Council, blaming the judiciary as the “single biggest hurdle” in India’s development, reignited a larger debate: Is the judiciary obstructing growth, or is it merely reflecting systemic governance failures? This question is crucial for UPSC aspirants because it encapsulates multiple administrative, ethical, and policy dimensions, from judicial accountability to executive responsibility and the balance of powers enshrined in the Constitution.

Why in the News?

At the Nyaya Nirman Conference, Sanjeev Sanyal claimed that India’s judiciary is the “single biggest hurdle” to achieving Viksit Bharat within 20–25 years. His comments triggered debate as it was not the first time that the judiciary was blamed for impeding development. What makes it significant is the reduction of a constitutional pillar into a scapegoat — reflecting a wider trend of executive deflection from governance failures. The issue is striking because judicial delays, though real, are often symptoms of legislative imprecision, government over-litigation, and vacant judicial posts, not merely judicial inefficiency.

Is the Judiciary the “Single Biggest Hurdle” to Development?

  1. Oversimplified blame – The criticism ignores that the judiciary merely enforces laws framed by Parliament. For instance, Section 12A of the Commercial Courts Act, 2015 mandates pre-suit mediation — a legislative choice, not a judicial one.
  2. Structural imbalance – Judicial delays stem from vacancies (over 30%), poor digital infrastructure, and overburdened lower courts rather than deliberate obstructionism.
  3. Reality check – India’s judiciary handles one of the world’s heaviest caseloads, with judges hearing 50–100 cases per day, highlighting efficiency within constraints.

What Lies Behind Judicial Delays?

  1. Government as the biggest litigant – The Union and State governments account for nearly 50% of all cases. Tax authorities, ministries, and PSUs appeal even routine orders, consuming judicial time and resources.
  2. Arbitrary tendering & contractual behaviour – Governments frequently breach contracts or impose unreasonable conditions, compelling contractors and citizens to litigate for basic rights.
  3. Vague and outdated laws – Laws are often drafted imprecisely, leading to interpretational disputes. The new criminal laws and upcoming Income-Tax Act recycle old frameworks with cosmetic changes.

Are Courts Overworked or Underworked?

  1. Myth of short working hours – Court sittings (10:30 AM–4 PM) mask the hours of preparatory and post-hearing work, including judgment writing and research.
  2. Vacations misunderstood – Vacations are largely used to complete reserved judgments, not for leisure. Vacation benches continue urgent hearings.
  3. Caseload pressure – District courts bear the brunt, where justice delivery meets the common citizen. High pendency here directly affects the perception of delay.

How Does Poor Law-Making Add to Judicial Burden?

  1. Ambiguity in drafting – The 99-to-1 problem, as noted by Sanyal himself, arises due to poorly framed laws meant to control the 1% of abusers, complicating life for the 99%.
  2. Linguistic confusion – Replacement of terms like “notwithstanding” with “irrespective” in new laws reflects shallow reform, creating fresh waves of litigation rather than clarity.
  3. Superficial reform – Cosmetic renaming (Codes → Sanhitas) in criminal law reform fails to address colonial legacies or procedural inefficiencies.

What is the Broader Message for Governance and Democracy?

  1. Deflecting accountability – Calling courts the bottleneck diverts attention from executive and legislative lapses.
  2. Constitutional balance – Judiciary serves as a check on arbitrary power, ensuring that speed does not override justice.
  3. True development – A “Viksit Bharat” cannot emerge by weakening judicial independence but by strengthening institutional capacity across all pillars of democracy.

Conclusion

Blaming the judiciary for India’s developmental delays is a misdiagnosis of a systemic illness. The judiciary, though imperfect, mirrors the inefficiencies entrenched in India’s governance — from poor drafting and over-litigation to resource neglect. The real challenge lies not in reducing judicial authority but in reforming governance practices, streamlining litigation, and investing in judicial infrastructure. A strong, independent judiciary is not an obstacle but the guarantor of sustainable development and rule of law.

The Crisis In The Middle East

Why Trump’s proposed stabilization force in Gaza will not find things easy

Introduction

With the Gaza conflict entering its third year, US President Donald Trump’s “Comprehensive Plan to End the Gaza Conflict” , a 20-point roadmap, has reignited global discussion on Palestine’s future. While both Israel and Hamas have agreed to an immediate ceasefire and prisoner exchange, the second, more ambitious part, a long-term peace framework and deployment of an International Stabilisation Force (ISF), faces deep geopolitical and operational challenges. The ISF, envisioned as a temporary yet long-term internal security mechanism under a “Board of Peace” chaired by Trump, is supposed to oversee “terror-free areas” handed over from Israel’s Defence Forces (IDF). But historical evidence from Afghanistan, Lebanon, and Iraq shows why such an effort may fail before it even begins.

What is the International Stabilisation Force (ISF)?

  1. Temporary but long-term mechanism: The ISF is designed to act as a “temporary” yet enduring internal security arrangement, forming part of a larger apolitical Palestinian committee.
  2. Trump’s oversight: It would be supervised by a “Board of Peace” chaired by Trump, tasked with ensuring security transition in Gaza.
  3. Mandate confusion: The ISF’s deployment is proposed “immediately” after Israeli Defence Forces withdraw from designated “terror-free zones.”
  4. Not UN-mandated: Unlike traditional UN peacekeeping forces, the ISF would lack international legitimacy and neutrality, as it is not under the UN Security Council’s (UNSC) authorisation.

Why is the ISF Not Comparable to UN Peacekeeping?

  1. Absence of neutrality: International peacekeeping has always required UN-mandated neutrality; the ISF, dominated by US and allied interests, lacks this legitimacy.
  2. Hostility in the region: Due to Arab hostility towards the US and Israel’s disregard for UN mandates, any non-UN force would face rejection from regional actors.
  3. UN precedent: Since 2004, UNSC resolutions have repeatedly called for peacekeeping only under UN authority, especially within occupied Palestinian territories until a two-state solution is achieved.
  4. Contradiction with global norms: Past experiences, from NATO’s ISAF in Afghanistan to multinational forces in Lebanon, show that non-UN interventions invite political opposition and legitimacy crises.

Why is Implementation Difficult in Palestine?

  1. Israel’s selective compliance: Israel has historically undermined UN peacekeeping mandates (e.g., UNIFIL in Lebanon) and is unlikely to cooperate fully with an externally led force.
  2. Hamas’ rejection of disarmament: Hamas has refused to disarm without Israel’s full withdrawal, a non-negotiable precondition.
  3. Political vacuum: There are no strong Palestinian institutions capable of ensuring political control and governance in post-conflict Gaza.
  4. UNSC resolutions ignored: While resolutions call for a two-state solution and prohibit occupation, Israel’s actions, including settlements and security zones, contravene these commitments.
  5. Lack of Arab consensus: Arab states remain divided on participation in any force seen as legitimising Israeli occupation.

What Lessons Do Historical Precedents Offer?

  1. Afghanistan (2001–2021): The NATO-led ISAF mission initially succeeded in stabilising Kabul but failed to create self-sustaining security institutions; the Taliban returned to power in 2021.
  2. Lebanon (1982–2000): The Multinational Force (MNF), dominated by the US and UK, withdrew amid heavy local opposition and attacks, transferring responsibility to the UN’s UNIFIL.
  3. Iraq (post-2003): The absence of a UN framework led to severe legitimacy deficits, insurgency, and long-term instability.
  4. These precedents underscore that external interventions without inclusive local ownership often end in strategic failure.

What Are the Broader Challenges in Trump’s Plan?

  1. Contradictory goals: Trump’s plan envisions Israel’s partial withdrawal but simultaneously retains security control, an inherent contradiction.
  2. Palestinian exclusion: The proposal does not recognise any Palestinian political institutions or grant them meaningful authority.
  3. Legal limitations: Without UNSC authorisation, the ISF would lack the legal basis to operate or enforce peace.
  4. Regional optics: Arab and Islamic states would perceive this as another Western attempt to militarise peace under the guise of “stabilisation.”

Conclusion

Trump’s proposed International Stabilisation Force may appear bold on paper, but it suffers from a crisis of legitimacy, political trust, and historical amnesia. Without a UN mandate, regional consensus, or Palestinian participation, the plan risks deepening divisions rather than healing them. As history shows, no external force can impose peace where sovereignty and justice remain unresolved.

[UPSC 2024] ‘Terrorism has become a significant threat to global peace and security.’ Evaluate the effectiveness of the United Nations Security Council’s Counter Terrorism Committee (CTC) and its associated bodies in addressing and mitigating this threat at the international level.

Linkage: Trump’s proposed International Stabilisation Force (ISF), lacking a UN mandate, underscores the limits of ad-hoc coalitions in tackling terrorism, contrasting with the UNSC-CTC’s institutional approach to coordinated, legitimate counter-terrorism efforts. It highlights the need for UN-backed, multilateral mechanisms over unilateral interventions for sustainable global peace.

Nobel and other Prizes

The Nobel laurates’ work has redefined the immune system itself

Introduction

For decades, the immune system was viewed as a binary apparatus either attacking foreign invaders or remaining silent toward the body’s own cells. This year’s Nobel laureates, Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi, dismantled that simplistic view by uncovering the critical role of regulatory T-cells (Tregs) and the FOXP3 gene in maintaining self-tolerance. Their findings fundamentally redefined how scientists perceive immune regulation and opened the path for precision immunotherapy — one of modern medicine’s most promising frontiers.

The Science of Self-Tolerance: Why It’s in the News

The Nobel Committee’s recognition of research on regulatory T-cells (Tregs) and FOXP3 marks a watershed moment in immunology. For the first time, the prize acknowledges discoveries that explain how the immune system prevents itself from attacking the body. The work explains why autoimmune disorders like Type 1 diabetes, rheumatoid arthritis, and lupus occur when this “self-check” mechanism fails. It also connects molecular immunology to emerging therapies for cancer and transplantation. This is a landmark shift from viewing immunity as mere “defence” to seeing it as a balance of activation and restraint, a concept that has redefined global biomedical research.

nobel

How the Nobel-winning Discovery Unfolded

  1. Early Understanding: In the 1990s, immunologists believed that self-reactive T-cells were deleted during their maturation. However, this could not explain why some autoreactive T-cells still existed in healthy people.
  2. Sakaguchi’s Breakthrough (1995): Identified a subset of CD4⁺ T-cells whose removal in mice led to multiple autoimmune disorders. Restoring them prevented disease — proving they act as regulators of immune overreaction.
  3. Discovery of FOXP3 Gene: Brunkow and Ramsdell, working in an industry lab (Celltech Chiroscience), traced severe autoimmune disease in male “scurfy” mice to a gene mutation on the X chromosome. They named it FOXP3.
  4. Human Correlation: Soon, mutations in FOXP3 were linked to lethal autoimmune syndromes in boys, confirming its pivotal role in human immune regulation.

How These Discoveries Transformed Immunology

  • Redefining the Immune System: The immune system is now seen not as an on/off mechanism but as a dynamic ecosystem that balances activation (attack) with restraint (tolerance).
  • New Therapeutic Frontiers:
    1. Autoimmune Diseases: Efforts are underway to expand or stabilise Tregs to curb harmful immune activation without broad immunosuppression.
    2. Transplant Medicine: Infusion of engineered Tregs improves graft acceptance and reduces rejection rates.
    3. Cancer Research: Selective depletion or reprogramming of tumour-associated Tregs enhances anti-tumour immunity without triggering autoimmunity.

From Lab to Life: The Translational Challenge

  1. Incremental Progress: Immunologists warn against overestimating breakthroughs. The immune system has multiple overlapping control layers, making clinical translation slow.
  2. High Cost Barrier: Cell-based therapies remain expensive, leading to inequitable access between high- and low-income populations.
  3. Ethical and Policy Dilemmas: Who gets access first? How do we regulate genetic manipulation or Treg engineering? These questions highlight the intersection of science, ethics, and public policy.

Private Sector and Scientific Innovation

  1. Industrial Discovery: The fact that Brunkow and Ramsdell made their discoveries in an industry setting (Celltech Chiroscience) underscores the potential of private-sector-led innovation in fundamental science.
  2. Public–Private Synergy: It reinforces how collaborations between academic research and biotech industry can accelerate discovery and application, a model India can emulate in its biotechnology policy framework.

Broader Implications for India and Global Health

  1. Indian Relevance: India’s growing burden of autoimmune diseases (such as lupus, celiac, and thyroiditis) highlights the need for indigenous immunogenetic research.
  2. Policy Perspective: Translating such research into affordable therapies aligns with National Biotechnology Development Strategy and Ayushman Bharat’s preventive healthcare goals.
  3. Global Impact: These discoveries open a new era of personalised immunotherapy, integrating molecular biology, bioethics, and equitable access.

Conclusion

The 2025 Nobel Prize reminds the world that progress in science often lies not in creating new weapons against disease but in understanding balance, the balance within nature and within ourselves. The discovery of Tregs and FOXP3 has rewritten textbooks, inspired therapies, and expanded our conception of what “self” and “immunity” truly mean. For policymakers and scientists alike, it represents the future, a fusion of molecular precision, ethical responsibility, and social justice.

[UPSC 2021] The Nobel Prize in Physics of 2014 was jointly awarded to Akasaki, Amano and Nakamura for the invention of Blue LEDs in the 1990s. How has this invention impacted the everyday life of human beings?

Linkage: Both the 2014 Nobel for Blue LEDs and the 2025 Nobel for Treg–FOXP3 discovery represent paradigm shifts where scientific breakthroughs moved from lab theory to real-world transformation — the former revolutionised energy efficiency, while the latter is redefining human health and immune regulation.

Tax Reforms

SC to examine Constitutional Validity of Securities Transaction Tax (STT)

Why in the News?

The Supreme Court of India has agreed to examine a petition challenging the constitutional validity of the Securities Transaction Tax (STT) imposed under the Finance Act, 2004.

Legal Context of this Case:

Petitioner: Aseem Juneja – contends that STT violates fundamental and economic rights.

Bench: Headed by Justice J.B. Pardiwala; formal notice issued to Union Ministry of Finance.

  • The plea invokes Article 265“No tax shall be levied or collected except by authority of law.”
  • The Court will assess reasonableness, equity, and proportionality in transaction-based taxation.
  • A ruling against STT may impact ₹30,000-crore annual revenue and require redesign of securities taxation.

SC to examine Constitutional Validity of Securities Transaction Tax (STT)

What is the Securities Transaction Tax (STT)?

  • About: A direct tax levied on purchase and sale of securities through recognised stock exchanges.
  • Introduction: Under the Finance Act, 2004, to ensure transparency and curb tax evasion in capital markets.
  • Objective: Replace complex capital-gains tracking with a small, upfront levy to counter under-reporting and increase tax buoyancy.
  • Administered by: Central Board of Direct Taxes (CBDT), Ministry of Finance.
  • Scope: Applies to-
    1. Equity shares of listed companies
    2. Derivatives (futures & options)
    3. Equity-oriented mutual funds and ETFs.
  • Purpose:
    • Simplify tax collection from capital market participants.
    • Create a traceable, automated tax mechanism.
    • Generate steady revenue while discouraging speculative trading.
  • Nature: A transaction-based tax (TBT) collected automatically at the time of trade, irrespective of overall profit or loss.
  • Distinctive features:
      • Applies even on loss-making trades payable merely for conducting a transaction.
      • Non-refundable and non-adjustable, unlike TDS.
      • Raises transaction costs for high-frequency traders.
  • Imposition of STT:
    • Mode of collection: Automatically deducted by stock exchanges on every taxable trade and deposited into the government account; Ensures near-universal compliance and minimal evasion.
    • Rate & coverage: Varies across instruments and between buy/sell transactions; Periodically revised through Union Budgets.

Key Grounds of Challenge:

  • Violation of Fundamental Rights:
    1. Article 14 (Equality): Unequal treatment; tax imposed irrespective of gain or loss.
    2. Article 19(1)(g) (Right to Trade): Penalises the act of trading itself.
    3. Article 21 (Livelihood & Dignity): Non-refundable levy burdens small traders.
  • Double Taxation: Traders already pay Capital Gains Tax on profits; STT adds a second layer on the same transaction.
  • Arbitrariness / Lack of Proportionality: Taxing even unprofitable transactions violates the principle of reasonable classification and fiscal fairness.
  • No Refund or Adjustment Mechanism: Absence of provision similar to TDS refunds; creates permanent loss even when income is negative.
  • Changed Circumstances: With digital audit trails, PAN-linked demat accounts, and near-complete transparency, the original rationale (to curb evasion) may no longer hold.

Labour, Jobs and Employment – Harmonization of labour laws, gender gap, unemployment, etc.

[6th October 2025] The Hindu Op-ed: Treating employment as a national priority

PYQ Relevance

[UPSC 2022] Economic growth in the recent past has been led by increase in labour productivity. Explain this statement. Suggest the growth pattern that will lead to creation of more jobs without compromising labour productivity

Linkage: The article highlights that India needs consistent, job-oriented growth policies focusing on labour-intensive sectors like textiles, tourism, and MSMEs to ensure “growth with jobs” rather than jobless productivity gains — directly aligning with the UPSC 2022 question’s call for a balanced growth pattern.

Mentor’s Comment

Employment generation is not just an economic issue, it is the moral and strategic foundation of India’s long-term growth story. As India moves toward Viksit Bharat 2047, it must transform its demographic dividend into productive employment. This article explores why employment must be treated as a national mission, the urgent need for an integrated framework, and how inclusive job creation can become the cornerstone of equitable and resilient growth.

Why in the News?

India is standing at a historic demographic crossroads, poised to add 133 million people to its working-age population in the next 25 years, accounting for 18% of the global workforce addition. However, this window is closing fast, with the working population expected to peak by 2043. Despite multiple government schemes, India still lacks a unified national framework for employment and livelihoods. Sanjiv Bajaj, Past President of CII, argues for treating employment as a national priority through a coherent, multi-level policy that integrates growth, skilling, social protection, and mobility. This issue is not merely about job numbers; it’s about ensuring equity, inclusion, and sustainable economic resilience. In a consumption-driven economy like India, employment is both the driver and the outcome of growth.

India’s Employment Challenge: The Demographic Window is Closing

  1. Demographic Dividend – India will add 133 million working-age individuals by 2047, nearly 18% of global addition, creating a unique window for productivity gains.
  2. Limited Timeframe – Worker population expected to peak by 2043, after which the demographic advantage will fade.
  3. Risk of Wasted Potential – Without large-scale, quality employment, India risks a demographic disaster rather than a dividend.
  4. Consumption Linkage – Quality jobs at scale broaden consumption, ensuring equitable and stable growth.

Why a Unified Employment Policy is the Need of the Hour?

  1. Fragmented Efforts – Despite initiatives like Skill India, PMEGP, and social security schemes, India lacks an Integrated National Employment Policy (INEP).
  2. Need for Coordination – Employment generation spans multiple ministries — Labour, Skill Development, Industry, and Education — requiring unified planning and execution.
  3. Institutional Mechanism – Bajaj recommends an Empowered Group of Secretaries for oversight and District Planning Committees for implementation.
  4. Policy Alignment – Trade, industrial, education, and labour policies must be synchronised to ensure job-oriented growth.

Bridging the Demand–Supply Divide in Labour Markets

  1. Demand-Side Drivers – Growth in high-employment-potential sectors like textiles, tourism, healthcare, agro-processing, real estate, and MSMEs.
  2. Supply-Side Gaps – Low employability of graduates, outdated curricula, and poor skilling alignment with emerging technologies (AI, robotics, green tech).
  3. Policy Reform – Curricula revamp, vocational training integration, and targeted skilling to meet industry needs.
  4. Mobility Barriers – Need for Centre–State cooperation on migration policies and worker support systems to promote “One India for Employment”.

Labour Codes, Urban Employment, and MSME Empowerment

  1. Labour Code Implementation – Timely execution of the four Labour Codes is critical, with clear transition and business support guidelines.
  2. MSMEs as Job Engines – Employing over 25 crore people, MSMEs need enhanced access to finance, markets, and technology to drive “growth with jobs.”
  3. Urban Employment Guarantee – Piloting schemes in selected cities can address urban job distress, akin to MGNREGA for urban India.
  4. Regional Focus – Targeted interventions in 100 underdeveloped districts and rural internships for graduates can promote balanced employment.

The Gig Economy Revolution

  1. Current Size – The gig economy currently employs 80 lakh–1.8 crore workers, expected to rise to 9 crore by 2030.
  2. Opportunity for Formalisation – With Tier-2 and Tier-3 cities participating, gig platforms can transform informal work into semi-formal, tech-enabled livelihoods.
  3. National Gig Policy – Should ensure worker protection, financial inclusion, and social security, supported by a centralised worker registry.
  4. Workplace Dignity – Ensure fair contracts, safety standards, and grievance redressal mechanisms.

Enhancing Female Labour Force Participation

  1. Current Gaps – India’s female labour force participation (FLFP) remains among the lowest globally.
  2. Policy Incentives – Employment-Linked Incentive (ELI) schemes, childcare and eldercare infrastructure, and formalising Anganwadi and ASHA roles can improve participation.
  3. Societal Barriers – Campaigns must challenge gender norms restricting women’s economic mobility.
  4. Economic Multiplier – A 10% rise in FLFP could add up to $700 billion to India’s GDP by 2025 (McKinsey estimate).
  5. The Missing Link: Reliable Employment Data
    • Data Gaps – Existing surveys understate informal and rural employment realities.
    • Need for Real-Time Data – A dedicated task force must improve methodologies and reduce data publication lag.
  6. Policy Relevance – High-frequency data can guide interventions in dynamic sectors like gig work and MSMEs.

Conclusion

India’s demographic dividend offers a fleeting window to achieve inclusive and sustainable growth. Treating employment as a national priority through an integrated policy, labour reforms, skill alignment, and gender inclusion is essential. Generating growth with jobs will ensure equitable prosperity and long-term resilience. Employment, therefore, is not just an economic goal, it is the foundation of nation-building and social justice.

Disasters and Disaster Management – Sendai Framework, Floods, Cyclones, etc.

India’s direction for disaster resilience

Introduction

India’s approach to disaster management has entered a new phase, one that focuses not only on response and recovery but equally on risk reduction, preparedness, and resilience. With climate change intensifying heat waves, floods, and landslides, the country’s policy architecture, led by the Ministry of Home Affairs (MHA) and the National Disaster Management Authority (NDMA), has embraced a multi-hazard, multi-stakeholder, and science-backed model. The guiding compass remains the Prime Minister’s Ten-Point Agenda on Disaster Risk Reduction (2016), now reinforced by major financial and institutional reforms.

Why in the News

For the first time, India’s disaster management strategy has been fully integrated into public finance planning, through the 15th Finance Commission’s ₹2.28 lakh crore allocation for disaster risk reduction over five years. This is a paradigm shift: from ad hoc post-disaster relief to structured, science-driven, and nature-based risk mitigation. With new funding for fire safety, glacial risk monitoring, and bioengineering-led landslide prevention, the government’s efforts represent a bold move towards building a climate-resilient India. The initiative is also significant because it establishes clear budget-to-project chains, accountability mechanisms, and cross-institutional linkages, something missing in previous regimes.

India’s Evolving Disaster Management Framework

  1. Multi-hazard nation: India faces diverse risks, floods, droughts, landslides, heat waves, cyclones, necessitating a multi-faceted approach.
  2. Shift in focus: Earlier systems were relief-centric; now, they integrate prevention, mitigation, capacity building, and sustainable reconstruction.
  3. Institutional leadership: The MHA and NDMA lead both pre- and post-disaster phases, ensuring coordination across States and institutions.
  4. Guiding vision: The Prime Minister’s Ten-Point Agenda (2016) promotes risk-informed investments, community participation, and technology integration.

How the 15th Finance Commission Redefined Disaster Financing

  • Historic allocation: ₹2.28 lakh crore ($30 billion) allocated over five years, a landmark in linking public finance with disaster resilience.
  • Segmented approach:
    • Preparedness and Capacity Building – 10%
    • Mitigation – 20%
    • Response – 40%
    • Reconstruction – 30%
  • End of debt dependency: Earlier, post-disaster reconstruction relied on multilateral loans; now, domestic fiscal mechanisms fill that gap.
  • Five priority reforms:
    1. Evaluate multi-hazard risks and prioritize them.
    2. Integrate scientific mitigation models into fiscal systems.
    3. Avoid duplication with other schemes.
    4. Enhance Centre-State and institutional synergy.
    5. Ensure light-touch regulation for flexibility and speed.

Investing in Pre-Disaster Preparedness and Capacity Building

  1. Fire safety modernization: ₹5,000 crore earmarked for upgrading urban and rural fire infrastructure.
  2. Community-based volunteers: Apda Mitra and Yuva Apda Mitra programs train 2.5 lakh volunteers to act as first responders.
  3. Strengthening institutions:
    1. National Institute of Disaster Management (NIDM) given a central role with geo-spatial training labs and action-based research.
    2. 36 streams of disaster management courses were introduced to mainstream DRR down to the panchayat level.
  4. Outcome: Shift from theoretical to practical, localised risk management.

Nature-Based Solutions and Climate Adaptation

  1. ₹10,000 crore mitigation projects across States emphasize nature-based, long-term solutions.
  2. Bioengineering for landslides: Stabilizing slopes in Himalayan regions using vegetation and soil binding.
  3. Urban flood control: Revitalizing water bodies and green spaces to restore natural drainage.
  4. Glacial lake monitoring: Remote sensing and automated stations for real-time surveillance.
  5. Forest fire prevention: Creating break lines, rejuvenating water bodies, and fuel evacuation corridors.
  6. Brahmaputra beels rejuvenation: Ecological restoration to mitigate monsoon flooding.
  7. Precursor success: National Cyclone Mitigation Programme (2011–22): ₹5,000 crore initiative, drastically reduced coastal vulnerability through shelters, embankments, and early warnings.

Building Technological and Institutional Resilience

  1. Advanced early warning systems: Multi-hazard platforms with seven-day lead time for cyclones.
  2. Common Alerting Protocol: Delivers region-specific alerts in local languages via multi-media.
  3. Human resource development:
    • Training at NIDM, NDRF Academy, and National Fire Service College for hundreds of officers annually.
    • Mock drills, school safety programmes, and local awareness drives improve community response.
    • Network of 327 universities: Build research and innovation pipelines for disaster science and policy.

India’s Global Leadership in Disaster Resilience

  1. Coalition for Disaster Resilient Infrastructure (CDRI): India-led global initiative for climate-resilient infrastructure systems.
  2. Active participation: G-20, SCO, BIMSTEC, and IORA platforms for sharing best practices.
  3. Knowledge exchange: India’s experience in nature-based DRR and community-driven risk management now shaping global policy dialogues.

Conclusion

India’s journey from disaster relief to disaster resilience marks a tectonic policy evolution. With fiscal integration, scientific innovation, and community participation, the nation is shifting from reactive recovery to proactive risk management. The emerging focus on nature-based, sustainable, and locally-driven mitigation reflects India’s understanding that resilience is not built after a disaster, it is cultivated every day, across every sector.

Alternative Dispute Resolution Mechanism – NCA, Lok Adalats, etc.

Why is ADR crucial for India’s courts?

Introduction

India’s courts are gasping under the weight of delays. According to the National Judicial Data Grid (NJDG), there are 4.57 crore pending cases, with nearly 63 lakh in High Courts and over 80,000 in the Supreme Court. For many citizens, justice delayed has become justice denied. Against this backdrop, the government’s renewed commitment to strengthen Alternative Dispute Resolution (ADR) marks an important turning point. ADR, rooted in India’s traditional dispute resolution practices, represents not just a procedural alternative, but a philosophical one. It shifts justice from confrontation to consensus, from hierarchy to harmony.

Why is ADR in the News?

The Minister of Law and Justice, Arjun Ram Meghwal, recently emphasized that India’s legal reforms must draw from its civilisational roots, particularly the doctrine of Panch Parmeshwar, the age-old village system of resolving disputes through collective wisdom. This announcement is significant for three reasons:

  1. Civilisational continuity: For the first time in recent years, legal reform is being explicitly linked to indigenous justice philosophy.
  2. Crisis in pendency: With cases exceeding 4.5 crore and vacancy rates of 33% in High Courts and 21% in district courts, India’s formal judicial system is overburdened beyond capacity.
  3. Demand for inclusion: ADR offers an alternative that is faster, cheaper, and socially inclusive, especially for marginalised groups who find formal litigation intimidating.

In essence, ADR is not just reform, it is rescue.

What is Alternative Dispute Resolution (ADR) and How Does It Work?

  1. Definition: ADR refers to mechanisms outside formal courts that help parties resolve disputes through mutual understanding, mediation, arbitration, conciliation, or Lok Adalats.
  2. Objective: To provide speedy, affordable, and amicable resolution while reducing judicial burden.
  3. Legal Framework:
    1. Article 39A of the Constitution mandates equal justice and free legal aid.
    2. Section 89 of the Code of Civil Procedure (CPC), 1908 formally recognizes ADR processes.
    3. Arbitration and Conciliation Act, 1996 (amended in 2021) gives statutory backing to arbitration agreements and conciliation processes.
  4. Time-bound resolution: The Arbitration Act, 2021 fixes a maximum 180-day period for dispute resolution — a stark contrast to the years spent in litigation.
    1. Exit Clause: If a party is dissatisfied, they can opt out after two sessions of mediation.
  5. Pre-litigation mediation: Encouraged for civil and commercial disputes, helping prevent new cases from entering the judicial pipeline.
  6. Example: Many commercial entities now resolve contractual disputes through institutional arbitration centres such as the Delhi International Arbitration Centre (DIAC), saving both time and cost.

How Do Lok Adalats Strengthen Access to Justice?

  1. Legal Basis: Lok Adalats are governed by the Legal Services Authorities Act, 1987, deriving strength from Article 39A.
  2. Types of Lok Adalats:
    • Permanent Lok Adalats (Section 22-B)
    • National Lok Adalats (held periodically)
    • E-Lok Adalats (virtual platforms launched post-COVID-19).
    • First Lok Adalat: Held in Gujarat in 1999 — symbolizing people’s justice at minimal cost.
  3. Finality of Decisions: Awards are final and binding, with no provision for appeal, ensuring swift closure.
  4. Safeguards: If dissatisfied, parties can still approach formal courts, preserving fairness.
  5. Impact: Lok Adalats have successfully resolved lakhs of cases annually, especially in motor accident and bank recovery disputes.

Why is Strengthening ADR a Necessity, Not a Choice?

  1. Judicial Overload: Judges in Uttar Pradesh, Himachal Pradesh, and Kerala handle over 4,000 cases each, severely limiting judicial attention.
  2. Delay and Disillusionment: A large portion of cases have been pending for over 10 years, eroding public faith in formal justice.
  3. Vacancies and Infrastructure Gaps: With 33% High Court and 21% district court vacancies, the backlog is worsening.
  4. Societal Benefits: As former CJI D.Y. Chandrachud noted, mediation is a tool for social change, aligning community norms with constitutional values through open dialogue.
  5. Cultural Relevance: ADR resonates with India’s traditional ethos, the village panchayat system was historically based on consensus, not contest.
  6. ADR thus not only decongests courts but humanises justice, making it conversational rather than confrontational.

Which States Have the Highest Backlog and Why It Matters

  1. Data from the India Justice Report 2025:
    • Andhra Pradesh, Uttar Pradesh, and Bihar have the highest backlog.
    • High Court pendency: Nearly 63 lakh cases.
    • District courts: The majority of the 4.57 crore pending cases.
  2. Vacancy crisis: Shortage of judges and staff deepens the delays.
  3. State ranking mechanism: The India Justice Report evaluates states on justice delivery, infrastructure, and human resources, revealing wide inter-State disparities.
  4. Call for reform: Strengthening ADR is crucial to ensure per capita justice delivery, especially in states lagging behind in judicial capacity.

Conclusion

ADR is not merely an alternative, it is an evolution of justice delivery in India. Rooted in India’s cultural traditions yet aligned with global best practices, ADR offers a pragmatic pathway to tackle pendency and ensure timely justice. Strengthening awareness, institutional capacity, and legal infrastructure around ADR will be key to transforming India from a litigating society into a resolving society — where justice is swift, simple, and shared.

Global Geological And Climatic Events

Cyclone Shakhti forms over Arabian Sea

Why in the News?

The India Meteorological Department (IMD) confirmed the formation of Cyclone Shakthi (named by Sri Lanka) over the northeast Arabian Sea.

About Cyclogenesis in the Arabian Sea:

  • Overview: Cyclogenesis is the formation and intensification of tropical cyclones under favourable oceanic and atmospheric conditions.
  • Seasonality: Most active during pre-monsoon (Apr–Jun) and post-monsoon (Oct–Dec) periods, when sea surface temperatures (SSTs) exceed 27 °C, moist convection intensifies, and the Coriolis effect induces rotation.
  • Formation Process: Warm moist air rises forming low pressure; latent heat of condensation deepens the system; upper-level outflow and low vertical wind shear sustain vertical growth, producing a warm eye with spiral rainbands.
  • Historical Pattern: The Arabian Sea was once less cyclone-prone than the Bay of Bengal due to cooler waters, dry winds, and high wind shear. Limited basin size and monsoon winds restricted cyclone growth.
  • Recent Change: Ocean warming and climate change have sharply increased cyclonic activity, making the region far more active in the last decade.
  • Rapid Intensification Trend: Short-term surges in wind speed (< 24 hrs) are now common, linked to warmer SSTs, Indian Ocean Dipole (IOD) shifts, and monsoon wind variability.
  • Oceanic–Climatic Drivers:
    • Indonesian Throughflow imports warm Pacific waters, raising SSTs.
    • Southern Ocean inflow brings cooler deep water, stabilising lower layers.
    • Dual cyclone seasons arise from monsoon wind reversal unique to the region.
  • Climate Change Impact:
    • IMD data show a 52 % rise in Arabian Sea cyclones in two decades, while Bay of Bengal activity slightly declined.
    • The Indian Ocean is among the fastest-warming oceans, increasing heat-moisture availability, altering global weather, and heightening coastal risks to life and infrastructure.

Recent Examples:

  • Tauktae (2021) – winds > 185 km/h, heavy damage along Gujarat–Konkan.
  • Biparjoy (2023) – lasted 13 days, fed by SSTs ~31 °C.
  • Tej (2023) – hit Oman & Yemen, showing cross-basin movement.
  • Shakthi (2025) – latest late-season, fast-intensifying cyclone.

Back2Basics: Tropical Cyclones

  • What is it: Large low-pressure systems over warm oceans, marked by rotating winds, heavy rain, and storm surges.
  • Conditions: Form when ocean temps >27°C, with moist rising air releasing latent heat to fuel convection.
  • Rotation: Driven by the Coriolis force – anticlockwise in Northern Hemisphere, clockwise in Southern.
  • Structure: Eye (calm), Eyewall (violent winds/rains), Rainbands (widespread showers).
  • Regional Names: Typhoons (Pacific), Hurricanes (Atlantic/Caribbean), Cyclones (Indian Ocean).
  • Drivers & Frequency: Common in Southeast Asia due to warm Pacific waters, El Niño/La Niña cycles, and climate change.
  • Impacts: Loss of life, property damage, flooding, soil salinisation, displacement, and disease outbreaks.
  • Climate Change Link: Global warming is making tropical cyclones stronger, less predictable, and more frequent, raising risks for coastal populations.

 

[UPSC 2020] Consider the following statements:

1. Jet streams occur in the Northern Hemisphere only.

2. Only some cyclones develop an eye.

3. The temperature inside the eye of a cyclone is nearly 10°C lesser than that of the surroundings.

India’s only Mud Volcano erupts after 20-years in Andamans

Why in the News?

India’s only mud volcano at Baratang Island in the Andaman and Nicobar Islands erupted after remaining dormant for over two decades.

India's only Mud Volcano erupts after 20-years in Andamans

Note: The Barren Island has erupted recently.

  • India’s only active lava volcano, located about 140 km from Port Blair.
  • Lies at the junction of the Indian and Burmese tectonic plates.
  • Eruption history: 1787 (first recorded), followed by episodes in 1991, 2005, 2017, November 2022, and September 2025.

About the Baratang Mud Volcano:

  • Location: Baratang Island, around 100–150 km north of Port Blair, situated in the North and Middle Andaman district.
  • Uniqueness: It is India’s only collection of mud volcanoes — 11 in total across the archipelago, 8 of which are on Baratang and Middle Andaman.
  • Eruptions: Significant eruptions were last reported in 2005; the 2025 eruption marks the first major event in 20 years.
  • Composition & Nature:
    • Emits cool mud, water, and gases (methane, hydrogen sulfide) rather than lava or fire.
    • Creates mud cones, bubbling pools, or dried crater-like formations.
    • Eruptions are low in intensity, involving slow oozing and gas bubbling rather than violent explosions.
  • Accessibility: A short 160-metre walk from the nearest road; the site lies near the Jarawa Tribal Reserve, where photography is prohibited for ethical and legal reasons.

Geological Formation and Features:

  • Tectonic Setting: Formed due to subduction of the Indian Plate beneath the Burmese Plate, leading to gas and fluid release from deep layers.
  • Mechanism:
    • Decomposition of organic matter underground produces gas pressure that pushes mud upwards.
    • These gases, along with water and sediments, escape to the surface, creating muddy eruptions and bubbling vents.
  • Temperature & Composition:
    • The expelled material is cool, unlike magmatic volcanoes.
    • Contains saline water, organic sediments, and gases, giving it a distinctive odour and appearance.
  • Earth Processes: The phenomenon helps scientists study fluid migration, methane emissions, and crustal deformation in active subduction zones.
[UPSC 2018] Consider the following statements:

1.The Barren Island volcano is an active volcano located in the Indian territory.

2.Barren Island lies about 140 km east of Great Nicobar.

3.The last time the Barren Island volcano erupted was in 1991 and it has remained inactive since then.

What are Small Modular Reactors (SMRs)?

Why in the News?

Major Indian private sector corporations expressed formal interest in setting up Small Modular Reactor (SMR)-based nuclear projects as part of the ‘Bharat Small Modular Reactors (BSMR)’ programme.

What is the Bharat Small Modular Reactors (BSMR) Programme?

  • Overview: India’s flagship nuclear programme, led by the Bhabha Atomic Research Centre (BARC) and the Nuclear Power Corporation of India Limited (NPCIL) under the Department of Atomic Energy (DAE).
  • Reactor Models:
    • BSMR-200 – 200 MWe Pressurized Water Reactor with passive safety.
    • BSR-220 – PHWR-based small reactor.
    • SMR-55 – 55 MWe PWR for captive or remote use.
  • Implementation: NPCIL retains ownership and operational control, while private companies fund and use generated power for captive needs. About 16 potential sites identified across Gujarat, Madhya Pradesh, Odisha, Andhra Pradesh, Jharkhand, and Chhattisgarh.
  • Policy & Financing: ₹20,000 crore allocated under the Nuclear Energy Mission for Viksit Bharat (2025-26) to operationalise five SMRs by 2033.

Foreign Policy Watch: India-Pakistan

[4th October 2025] The Hindu Op-ed: The maritime signalling after Operation Sindoor

PYQ Relevance

[UPSC 2022] What are the maritime security challenges in India? Discuss the organizational, technical and procedural initiatives taken to improve the maritime security.

Linkage: The post-Operation Sindoor naval manoeuvres highlight India’s evolving response to maritime security challenges, reflecting the same organizational, technical, and procedural upgradation, from indigenous fleet expansion (INS Nistar) to enhanced Indo-Pacific coordination, envisaged in this PYQ.

Mentor’s Comment

Operation Sindoor may have concluded in the skies, but its echoes now reverberate across the sea. With both India and Pakistan recalibrating their naval postures, the maritime domain has emerged as the new theatre of strategic competition. This article explores how post-Sindoor developments from naval manoeuvres to capability upgrades are reshaping deterrence dynamics, inviting questions about escalation control, external involvement, and evolving doctrines in the Indian Ocean.

Introduction

While the standoff with Pakistan in May 2025 ended in the air domain, subsequent developments reveal a strategic shift to the maritime theatre. Both nations are now engaged in assertive naval signalling, deploying assets, testing missiles, and broadcasting intent. India’s Operation Sindoor, initially a demonstration of naval deterrence, has transitioned into a long-term posture recalibration with new vessels, strategic patrols, and sharper rhetoric. Defence Minister Rajnath Singh’s warning on October 2 about a “resounding response” to any Pakistani misadventure in the Sir Creek region, coupled with Pakistan’s launch of the Hangor-class submarine PNS Mangro and missile tests, underline a renewed contest at sea. This is significant — because for decades, the India-Pakistan rivalry was air and land-focused, not maritime. The sea, it seems, is now the new frontier of strategic signalling.

Why in the News

The post-Operation Sindoor phase marks the first time in decades that India and Pakistan are simultaneously signalling deterrence through sustained maritime manoeuvres, overlapping missile tests, and forward deployments. India has conducted its first joint patrols with the Philippines in the South China Sea and commissioned the indigenously designed INS Nistar. Pakistan, meanwhile, has expanded naval activity from Karachi to Gwadar, launched new submarines and ballistic missiles, and tested the P282 ship-launched missile. This pattern is unprecedented not just in intensity but in its potential to redefine deterrence stability and crisis escalation in the Indian Ocean.

Why is the Maritime Theatre Gaining Strategic Centrality?

  1. Shift from air to sea: After Operation Sindoor’s air engagement, both sides are redirecting deterrence signalling to the Arabian Sea, with forward deployments and missile tests.
  2. Recalibration of naval posture: India’s Operation Sindoor emphasised a forward deterrent posture, a readiness to act first if provoked.
  3. Symbolic rhetoric: Defence Minister Rajnath Singh’s statement evoking the 1965 war reinforced the seriousness of India’s deterrent message.

What Signals Are India and Pakistan Sending at Sea?

  1. India’s assertive posture: Through INS Nistar, stealth frigates, and joint patrols, India projects both self-reliance and Indo-Pacific alignment.
  2. Pakistan’s parallel moves: Launch of PNS Mangro, expansion of infrastructure in Sir Creek, and P282 missile tests signify deterrence-by-denial.
  3. Operational friction: Overlapping NOTAMs and live-fire drills, sometimes just 60 nautical miles apart, indicate heightened tension and risk of miscalculation.

How Does the Naval Balance of Power Look Now?

  1. India’s advantage but narrowing: Despite a numerical and geographical edge, India’s fleet faces ageing issues, raising modernization concerns.
  2. Pakistan’s modernization: With Chinese-designed submarines and Babur-class corvettes from Türkiye, Pakistan’s Navy now wields improved radar, EW, and anti-surface weaponry.
  3. Emerging parity: The Navy Chief’s acknowledgment of Pakistan’s “surprising growth” underscores a reality where India’s maritime superiority is no longer absolute.

What Makes Maritime Escalation More Risky?

  1. Harder escalation control: Unlike air skirmishes, naval engagements are slow, continuous, and harder to de-escalate.
  2. Psychological vulnerability: Memories of 1971 naval strikes amplify Pakistan’s sensitivity; even limited Indian action could trigger disproportionate reaction.
  3. Anti-Access/Area Denial (A2/AD): Pakistan’s Gwadar and Karachi hubs serve both operational and psychological roles in denying India unchallenged dominance.
  4. Chinese factor: The PLAN’s presence at Gwadar increases risk of external entanglement in future crises.

Is There an External and Doctrinal Dimension?

  1. China’s role: Chinese involvement in Gwadar and Karachi raises fears of dual-use support during crises.
  2. Türkiye’s growing linkages: Supply and training cooperation with Pakistan diversify its defence dependencies, complicating India’s strategic calculations.
  3. India’s Indo-Pacific strategy: Joint patrols and multilateral engagement hint at a twofold Indian approach, deterrence towards Pakistan and cooperation across the Indo-Pacific.
  4. Doctrinal drift: Both nations risk anchoring strategy in outdated crisis models, despite new technologies like drones and hypersonic missiles changing escalation ladders.

Does the Emerging Maritime Pattern Help or Hurt Stability?

  1. Persistent signalling: Continuous naval presence, unlike air sorties, lingers — shaping adversarial perception and intent.
  2. Learning by observation: Regular drills, while risky, can create mutual operational awareness that paradoxically reduces fog of war.
  3. Dual outcome: The same actions that raise tensions might also stabilize future crises through transparency of capability and doctrine.

Conclusion

Operation Sindoor may have ended, but its maritime aftermath is redrawing South Asia’s deterrence geography. The Arabian Sea has emerged as a stage for calibrated signalling, doctrinal experimentation, and external power play. India faces a dual challenge to assert deterrence without escalation and prepare for future crises where the sea, not the sky, sets the tone. The Indian Navy’s modernization drive, from indigenously designed vessels to Indo-Pacific collaborations, suggests a conscious shift one that seeks to combine strategic restraint with decisive readiness. The sea, long a silent frontier, is now a theatre of both opportunity and peril.
