How different are Supercomputers to normal computers?

Why in the News?

This newscard is an excerpt from the original article published in The Hindu.

What is a Supercomputer?

  • Overview: A high-performance computing system capable of trillions to quintillions of calculations per second.
  • Parallel Computing: Uses thousands of processors working together instead of relying on a single fast processor.
  • Applications: Climate modelling, nuclear simulations, black hole research, drug discovery, and artificial intelligence training.
  • Performance Measure: FLOPs (floating-point operations per second); advanced machines now achieve exaflop levels (10¹⁸ calculations/sec).

How Supercomputers Differ from Normal Computers

  • Speed: Laptops perform billions of FLOPs; supercomputers perform quintillions.
  • Parallelism: PCs use one or few processors; supercomputers employ thousands to millions of cores.
  • Structure: Built of interconnected nodes (processor + memory bundles) linked by ultra-fast networks.
  • Storage: Manage petabytes of data, unlike gigabytes/terabytes in personal devices.
  • Cooling & Power: Need specialised cooling (water/immersion) and consume electricity equal to a small town.
  • Usage: PCs run interactive apps; supercomputers run scheduled jobs remotely for scientists and researchers.

India’s journey in Supercomputing:

  • Early Efforts: Began with C-DAC’s PARAM 8000 (1991) after Western import restrictions.
  • National Supercomputing Mission (2015): Jointly by DST & Ministry of Electronics and IT; implemented by C-DAC and IISc to build 70+ systems.
  • Major Systems (2025):
    • AIRAWAT-PSAI (C-DAC, Pune) – fastest in India (8.5 PF, global rank 136).
    • PARAM Siddhi-AI – global AI leader.
    • Pratyush (IITM, Pune) – weather & climate (3.76 PF).
    • Mihir (NCMRWF, Noida) – medium-range weather (2.57 PF).
    • PARAM Pravega (IISc, Bengaluru) – academic use (>3.3 PF).
  • Indigenous Push: PARAM Rudra (2024) with Indian servers and software stack.
  • Applications: Monsoon forecasting, Himalayan research, defence simulations, AI, drug design, materials science.
  • Current Capacity: 34+ supercomputers with ~35 petaflops; plans for exascale systems underway.
[UPSC 2014] Param Padma, which was in the news recently, is:

(a) a new Civilian Award instituted by the Government of India

(b) the name of a supercomputer developed by India *

(c) the name given to a proposed network of canals linking northern and southern rivers of India

(d) a software programme to facilitate e-governance in Madhya Pradesh

Biofuel Policy

Is it feasible to blend Isobutanol and Diesel?Ā 

Why in the News?

The Union Transport Minister has announced that the Automotive Research Association of India (ARAI) is studying the feasibility of blending Isobutanol with Diesel after ethanol–diesel blending attempts failed.

About Isobutanol:

  • What is it: A four-carbon alcohol (Cā‚„H₁₀O), clear, flammable, and traditionally used as a solvent in paints, coatings, and chemical industries.
  • Production: Derived either from petrochemical processes or by fermenting sugarcane, molasses, and grains with engineered microbes.
  • Fuel Properties:
    • Higher energy density than ethanol, closer to diesel.
    • Lower hygroscopicity (absorbs less water), reducing rust and corrosion in engines and pipelines.
    • Higher flash point than ethanol, making it safer for storage and transport.

Isobutanol–Diesel Blending and Benefits:

  • Compatibility: Unlike ethanol, isobutanol blends well with diesel without extra chemicals.
  • Economic Feasibility: Can be produced in existing ethanol plants with minor changes.
  • Agricultural Support: Creates demand for sugarcane by-products, helping farmers and managing sugar surplus.
  • Energy Security: Reduces reliance on imported fossil fuels and saves foreign exchange.
  • Global First: Pilot studies may make India the first country to use isobutanol–diesel blends.

Challenges and Risks:

  • Combustion Issues: Has a lower cetane number than diesel, causing poor combustion quality.
  • Engine Risks: Can trigger diesel knock (uneven burning, power loss, engine damage).
  • Mixing Limitations: Blending challenges exist but can be partly solved with biodiesel addition.
  • Cost Factor: Requires additives to restore cetane number, increasing costs.
  • Blending Limit: Experts suggest ≤10% blending to avoid harm.
  • Pilot Phase: Testing will take ~18 months before possible large-scale adoption.
[UPSC 2020] With reference to green hydrogen, consider the following statements:

1. It can be used directly as a fuel for internal combustion.

2. It can be blended with natural gas and used as fuel for heat or power generation.

3. It can be used in the hydrogen fuel cell to run vehicles.

How many of the above statements are correct?

Options: (a) Only one (b) Only two (c) All three* (d) None

Air Pollution

ā€˜Smog-eating’ photocatalytic coatings on roads to curb pollution

Why in the News?

Delhi government has announced a feasibility study to test photocatalytic coatings on roads, pavements, and public spaces to bring visible improvements in air quality.

About Smog:

  • Overview: Combination of smoke and fog, forming smoky fog with soot, gases, and moisture.
  • Components: Includes soot particulates, sulphur dioxide (SOā‚‚), nitrogen dioxide (NOā‚‚), hydrocarbons, carbon monoxide (CO), and ozone (Oā‚ƒ).
  • Types:

    1. Sulfurous Smog (London Smog) – Caused by burning coal and sulphur-bearing fuels; worsened by dampness and particulates.
    2. Photochemical Smog (Los Angeles Smog) – Produced when NOā‚“ and hydrocarbons react under sunlight, forming ozone; appears as a brownish haze with respiratory effects.
  • Pollutants:

    1. Primary pollutants: Directly emitted (NOā‚‚, SOā‚‚, hydrocarbons).
    2. Secondary pollutants:Ā  Formed via reactions (ozone, acid rain).
  • Haze vs. Smog: Haze = dry particles reducing visibility; Smog = pollutants with condensation.
  • Effects: Respiratory distress, eye irritation, plant damage, reduced visibility, carcinogenic risk, worsened by inversion layers and low rainfall.

What are ā€œSmog-Eatingā€ Coatings?

  • Technology: Photocatalytic coatings using titanium dioxide (TiOā‚‚) on roads, pavements, and public surfaces.
  • Function: Under sunlight, TiOā‚‚ breaks down pollutants like NOā‚‚ and hydrocarbons into less harmful compounds.
  • Advantages: Low-cost, stable, compatible with traditional materials, effective in depollution and creating self-cleaning surfaces.

Delhi Government Plan

  • Plan: If viable, Cabinet proposal for citywide rollout at busy corridors, markets, and public spaces.
  • Evaluation: Study to assess cost-effectiveness, safety, and sustainability while shortlisting suppliers.
  • Strategic Context: Part of a 24Ɨ7, year-round environmental action plan using technology-driven interventions.
[UPSC 2013] Photochemical smog is a resultant of the reaction among-

(a) NOā‚‚, Oā‚ƒ and peroxyacetyl nitrate in the prescence of sunlight *

(b) COā‚‚, Oā‚‚, and peroxyacetyl nitrate in the presence of sunlight

(c) CO, COā‚‚, and NOā‚‚ at low temperature

(d) high concentration of NOā‚‚, Oā‚ƒ and CO in the evening

Terrorism and Challenges Related To It

[20th September 2025] The Hindu Op-ed: The Saudi-Pakistan pact is a dodgy insurance policy

PYQ Relevance:

[UPSC 2018] In what ways would the ongoing US–Iran Nuclear Pact controversy affect the national interest of India? How should India respond to this situation?

Linkage: The Saudi–Pakistan SMDA, like the earlier US–Iran Nuclear Pact controversy, reshapes West Asian alignments and directly impacts India’s energy security, diaspora safety, and regional stability. Just as India had to balance between Iran, the U.S., and Gulf partners in 2018, it must now carefully hedge between Riyadh and Islamabad while safeguarding its own strategic interests.

Mentor’s Comment

The Strategic Mutual Defence Agreement (SMDA) signed between Saudi Arabia and Pakistan in September 2025 has been described as a pact of optics rather than substance. Its timing, context, and asymmetrical calculations raise questions on whether it strengthens West Asian security or merely signals short-term adjustments. For UPSC aspirants, this episode provides insights into the shifting geopolitics of South West Asia, Pakistan’s strategic opportunism, Saudi Arabia’s security dilemmas, and India’s balancing role.

Introduction

On 17 September 2025, Saudi Crown Prince Mohammed bin Salman and Pakistani Premier Shahbaz Sharif signed the Strategic Mutual Defence Agreement (SMDA) in Riyadh, with Field Marshal Asim Munir in attendance. While presented as a landmark pact, its real significance lies in the optics of security reassurance amid the shifting sands of Middle Eastern politics. Both nations have a chequered past of military cooperation, rooted in shared faith but divided by divergent threat perceptions. The agreement’s asymmetrical benefits, U.S. undertones, and implications for India make it geopolitically consequential.

Why is the SMDA in the news and why is it significant?

  1. First major pact in decades: The last high-point of Saudi–Pakistan defence ties was in the 1979–89 period, when 20,000 Pakistani troops protected Saudi Arabia and the Holy Harams.
  2. Optical reassurance: The SMDA is viewed more as a symbolic gesture than a substantive alliance, designed to show unity amidst rising threats from Iran, Yemen, and Israel.
  3. Geopolitical urgency: Triggered by the September 9 Israeli air strike in Doha (Qatar), the pact signals waning U.S. credibility as a security guarantor for the Gulf.
  4. Big deal: Pakistan is now a declared nuclear state, raising speculation of nuclear cooperation with Riyadh, though practical transfer remains improbable.

What has been the history of Saudi-Pakistan defence cooperation?

  1. Golden phase (1979–89): 20,000 Pakistani soldiers stationed in Saudi Arabia to protect the monarchy and act against Iran and Yemen.
  2. Saudi view: Treated Pakistani forces as paid Praetorian Guards, limiting their autonomy.
  3. Pakistani view: Resented lack of command; exclusion of Shia troops created tensions.
  4. 1990 onwards: Pakistan refused Saudi requests during major crises (Iraq’s Kuwait invasion, Yemeni war), limiting its role to protecting the Holy Harams.

How has the United States influenced the SMDA?

  1. Pentagon as the guarantor: U.S. historically underpinned Saudi–Pak defence ties ā€œover-the-horizon.ā€
  2. Trump’s role: In June 2025, Field Marshal Munir’s ā€œprivate lunchā€ with Trump in Washington signalled Washington’s blessing.
  3. Israeli factor: Saudi Arabia wanted a U.S. defence pact and nuclear technology in exchange for recognising Israel. The Hamas attack on Israel in Oct 2023 derailed the plan, leaving the SMDA as a consolation prize.
  4. Credibility gap: The U.S. failure to defend Qatar against Israeli strikes exposed fragility in Gulf security guarantees.

What are Riyadh’s calculations from the SMDA?

  1. Avoid Arab troops: Past experience with Arab/Turkish troops created risks of ā€œpolitical pollination.
  2. Massive arms imports: Saudi Arabia has ordered $100 billion worth of U.S. weapons in 2025.
  3. Nuclear hedge: Pakistan’s nuclear capability could deter Iran if it goes nuclear.
  4. Chinese factor: Pakistan’s ties with China may complicate Riyadh’s trust.
  5. Realistic expectation: Riyadh foresees smaller Pakistani footprints than before, given past frictions.

What are Islamabad’s calculations from the SMDA?

  1. Asymmetrical gains: No intention to fight Saudi wars against Iran, Yemen, or Israel.
  2. Strategic opportunism: Exploit Saudi insecurity to gain funds, oil, defence hardware, and training.
  3. Personal aggrandisement:Pakistan’s military elite aim to monetise ā€œIOUsā€ from Riyadh and Washington.
  4. Regional calculus: Hopes trilateral axis will offset its strategic disadvantage against India.

What does the SMDA mean for India?

  1. Energy linkages: India is the third-largest oil importer and among Saudi’s top trade partners.
  2. Diaspora factor: Largest expatriate community in Saudi Arabia, valued for skills and neutrality.
  3. Diplomatic capital: Post-2014 outreach has created defence and intelligence-sharing frameworks.
  4. Saudi balancing act: Riyadh assured Reuters that ties with India remain ā€œrobust,ā€ acknowledging India’s nuclear status and geoeconomic heft.
  5. Implication: India must remain vigilant, building greater Arabian Sea synergies to counterbalance tactical moves by Pakistan.

Conclusion

The Saudi–Pakistan pact is less a robust security alliance and more a political insurance policy, crafted in haste amid shifting regional dynamics. While it temporarily reassures Riyadh and monetarily benefits Islamabad, its sustainability remains doubtful due to divergent threat perceptions, nuclear sensitivities, and overlapping U.S.–China rivalries. For India, the SMDA underscores the need to strengthen its energy diplomacy, diaspora leverage, and strategic partnerships with Riyadh, while maintaining watchfulness over Pakistan’s manoeuvres.

A climate-health vision with lessons from India

Introduction

At the Global Conference on Climate and Health (July 2025, Brazil), 90 countries shaped the BelƩm Health Action Plan, which will guide the climate-health agenda at COP30 (Nov 2025). Ironically, India, despite having some of the most instructive welfare experiences linking climate and health, was not officially represented, a missed opportunity to emerge as a global exemplar.

India’s non-health interventions like the Pradhan Mantri Poshan Shakti Nirman (PM POSHAN), Swachh Bharat Abhiyan, Mahatma Gandhi National Rural Employment Guarantee Act (MNREGA), and Pradhan Mantri Ujjwala Yojana (PMUY) offer rich lessons for operationalising an integrated climate-health framework. They reveal that intentional, intersectoral action can yield multiple dividends: improved nutrition, reduced pollution, restored ecosystems, and healthier communities.

Why is this news significant?

India’s absence at BelĆ©m stands out because for the first time a global platform is drafting a climate-health action plan. While India has often been viewed through the prism of its energy transition challenges, this moment presented a chance to highlight its homegrown welfare successes with global resonance. The paradox is striking: even without designing policies as ā€œclimate policies,ā€ India has reaped climate-health co-benefits, unlike many countries still struggling to integrate the two. Yet, persistent failures like high LPG refill costs in PMUY and siloed governance highlight the scale of unfinished work.

What is the BelƩm Health Action Plan (BHAP)?

  • The BHAP is a strategic framework being finalized ahead of COP30 (Nov 2025, BelĆ©m, Brazil) intended to integrate health into climate change adaptation.
  • It emphasizes health equity, climate justice, and social participation alongside strengthening health systems to be resilient in face of climate change.

Key Features / Action Lines

Some of its priority action lines include:

  • Surveillance & Monitoring:
    • Linking climate/environmental data with health surveillance, early warning systems (for heatwaves, epidemics, etc.).
    • Real-time data, local / community-level monitoring.
  • Evidence-Based Policy Strategy & Capacity Building:
    • Training health workforce, integrating mental health & psychosocial support measures.
    • Gender-responsive, inclusive policies, recognizing most vulnerable groups (women, Indigenous people, persons with disabilities).
  • Innovation & Production:
    • Resilient infrastructure and services (e.g. climate-adapted health facilities), sustainable supply chains.
    • Focus on blended financing and mobilizing investments to make health systems adaptive and equitable.
  • Cross-cutting priorities:
    • Health equity & climate justice: ensuring that adaptation efforts do not further marginalize vulnerable groups.
    • Leadership & governance: accountability, social participation from civil society, clear institutional roles.

What lessons do India’s welfare programmes offer for climate-health synergy?

  1. PM POSHAN: Covers 11 crore children in 11 lakh schools, linking nutrition, agriculture, and education. Promotion of millets strengthens climate-resilient food systems.
  2. Swachh Bharat Abhiyan: Improved sanitation, public health, and environmental sustainability, while embedding dignity and cultural symbolism via Gandhi’s vision.
  3. MNREGA: Enhanced livelihood security while simultaneously restoring degraded ecosystems through water conservation and afforestation.
  4. PM Ujjwala Yojana (PMUY): Transition to clean cooking fuel cut household air pollution — a leading cause of respiratory illness — while reducing carbon emissions.

How has leadership and community engagement shaped outcomes?

  1. Political leadership: Direct involvement of the Prime Minister gave Swachh Bharat and PMUY inter-ministerial traction and public legitimacy.
  2. Community engagement: PM POSHAN leveraged parent-teacher committees, Swachh Bharat invoked cultural pride in cleanliness, ensuring local ownership.
  3. Cultural anchoring: Climate action framed as health protection resonates more deeply than carbon metrics.

What structural challenges persist in implementation?

  1. Administrative silos: Divergent sectoral mandates limit integrated outcomes.
  2. High refill costs in PMUY: Oil marketing interests often outweigh beneficiary affordability.
  3. Social barriers: Gender norms and cultural practices limit uptake of clean fuel and sanitation.
  4. Output vs. outcome gap: Programmes measure immediate coverage but not long-term health-climate impact.

What framework does India’s experience suggest for climate-health governance?

  1. Strategic prioritisation: Frame climate action as immediate health security, not distant environmental risk.
  2. Procedural integration: Embed health impact assessments into energy, transport, and urban policies.
  3. Participatory implementation: Leverage ASHA workers, SHGs, Panchayats as health-climate advocates.

Why is this vision critical for the future?

  1. High stakes: Delinking climate and health crises leads to fragmented solutions with escalating costs.
  2. Transformative potential: An intersectoral, whole-of-society approach could position India as a global leader in climate-health governance.
  3. Clear choice: Continue piecemeal efforts or pioneer a bold model aligning welfare with planetary health.

Conclusion

India’s welfare architecture has shown that policies designed for social welfare can unintentionally become climate-health interventions. The challenge now is to make this synergy intentional and institutionalised, with robust political framing, procedural integration, and community mobilisation. At a time when the world is drafting a global climate-health action plan, India’s absence from the table is a wake-up call: to convert scattered lessons into a coherent model of governance that others can emulate.

Value Addition

Key Concepts

  1. Climate-Health Nexus: Environmental policies often have unintended health impacts; health policies also influence climate outcomes.
  2. Co-Benefits Approach: One intervention (e.g., PMUY for clean cooking fuel) yields multiple dividends (better health, women’s empowerment, reduced emissions).
  3. Whole-of-Society Approach: Intersectoral coordination between ministries, communities, and local bodies ensures impact.
  4. Output vs Outcome Gap: Many Indian schemes achieve outputs (LPG connections, toilets built) but outcomes (sustained use, cleaner air, health equity) remain weak.

Important Data / Reports

  1. WHO Report (2021): Air pollution causes 7 million premature deaths annually worldwide.
  2. Lancet Countdown on Health and Climate Change (2022): South Asia faces one of the highest global burdens of climate-related health risks.
  3. India’s National Family Health Survey (NFHS-5, 2021): Despite welfare schemes, 35.5% of children under 5 are stunted and 32.1% are underweight, showing links between nutrition, climate resilience, and health.
  4. UNDP (2023): Every $1 invested in resilience and adaptation yields $4 in avoided losses.
  5. Global Conference on Climate & Health (BelƩm Plan, 2025): First global blueprint on climate-health integration.

PYQ Linkage:

[UPSC 2017] ā€˜Climate Change’ is a global problem. How India will be affected by climate change? How Himalayan and coastal states of India will be affected by climate change?

Linkage: India’s welfare schemes like PM POSHAN, PMUY, Swachh Bharat and MNREGA demonstrate that non-health interventions can mitigate climate impacts while improving public health. The Himalayan and coastal states, most vulnerable to warming, floods, and sea-level rise, can benefit from such intersectoral, resilience-building models. Thus, India’s climate-health vision provides practical pathways to address both regional vulnerabilities and national climate commitments.

Foreign Policy Watch: India-Nepal

Turmoil, tragedy, and tenacity in Nepal

Introduction

In early September 2025, Nepal was rocked by its most intense youth uprising since the end of monarchy in 2008. Peaceful demonstrations against corruption and inequality, largely organised online, escalated into violent clashes, leaving 73 dead and vital government institutions in flames. The resignation of Oli and the appointment of Sushila Karki as interim Prime Minister has opened a critical transition. The protests underscore the growing role of Gen Z digital activism in reshaping political landscapes.

Timeline of the protests

  1. 4 Sept 2025: Government orders registration/ban of 26 social media platforms (trigger).
  2. Early Sept (pre-8): Weeks of online organising; #NepoBabies and related trends circulate.
  3. 8 Sept 2025 (Day 1): Large peaceful gatherings at Maitighar Mandala; clashes erupt; official reports of first deaths (ā‰ˆ19 reported that night).
  4. 9 Sept 2025 (Day 2): Violence spreads; Parliament, Supreme Court, Singha Durbar attacked and some set on fire; casualty and injury figures climb.
  5. 10–12 Sept 2025: Army deployed to secure cities; Home Minister and Oli resign; negotiations with youth representatives begin.
  6. 12–14 Sept 2025: Sushila Karki sworn in as interim prime minister; Parliament dissolved; elections scheduled for March (caretaker mandate announced).

How did legal restraints on digital space ignite a national revolt?

  1. Trigger — Social Media Ban: On 4 September 2025, the government ordered the blocking/registration of 26 social media platforms, including X, Facebook, and Instagram.
  2. Impact: This cut off Gen-Z’s primary space for organisation, expression, and economic activity, seen as a direct assault on civic freedom.
  3. Outcome: Scattered anger was transformed into coordinated protests.
  4. Example: Youth groups used Discord and TikTok to plan assemblies at Maitighar Mandala and coordinate marches towards Parliament.

What were the structural grievances behind the uprising?

  1. Corruption & Elitism: Perceptions of elite capture, misuse of resources, and impunity fuelled resentment.
  2. Symbol of Rage: The #NepoKids / #NepoBabies campaign exposed politicians’ children flaunting luxury while ordinary youth faced precarity.
  3. Example: Viral clips contrasting lavish lifestyles with student unemployment intensified outrage.
  4. Data: Transparency International (2025): Nepal ranked 107/180 on the Corruption Perceptions Index (CPI score: 34).

Why did peaceful protests become deadly and destructive?

  1. Escalation: Initially peaceful gatherings on 8 September were dispersed using tear gas and reportedly live ammunition.
  2. Violence: Retaliatory riots followed; demonstrators targeted symbols of state power.
  3. Example: On 9 September, Parliament, Supreme Court, and Singha Durbar were set ablaze; crucial judicial records were damaged.
  4. Data: 72–73 deaths reported, with hundreds injured, mostly between ages 19–24.

What immediate political fallout followed the unrest?

  1. Leadership Change: Home Minister resigned on 8 Sept; PM K.P. Sharma Oli stepped down on 9 Sept.
  2. Caretaker Transition: The Army mediated negotiations; Parliament was dissolved.
  3. Interim PM: Sushila Karki, former Chief Justice, sworn in on 12 Sept 2025, mandated to hold elections within six months.
    • Karki visited hospitals, assured investigations, and pledged accountability and timely polls.

How did digital tools shape both mobilisation and misinformation?

  1. Mobilisation: Platforms like Discord, TikTok, and hashtags enabled rapid outreach, meme-culture, and youth identity in protests.
  2. Creativity: Anime/manga flags and viral videos energised Gen-Z demonstrations.
  3. Misinformation: False reports and AI-generated images (e.g., Pashupati Temple ā€œburningā€) created panic and confusion.
  4. Example: Fake claims about a senior politician’s family being killed circulated widely before being disproved.

What are the main challenges facing Nepal’s interim rulers?

  1. Legitimacy Concerns: Traditional political parties, deposed MPs, and royalist factions question the constitutional mandate of the interim set-up.
  2. Balancing Act: The government must address youth expectations of anti-corruption and inclusivity while ensuring political buy-in from entrenched elites.
  3. Stability: Conducting free and fair elections by March 2026 without undermining the democratic spirit of Gen-Z protests remains the foremost task.
  4. Example: Political parties and royalists have already raised doubts over Karki’s legitimacy despite broad youth support.

Implications for Nepal (domestic)

  • Political Legitimacy and Party Renewal
    • The protests revealed a deep erosion of trust in established parties.
    • Unless political parties reform and integrate youth aspirations into institutional politics, cycles of protest could continue.
    • Revamping youth wings and embracing inclusivity may be crucial for long-term stability.
    • (Echoes analysts’ calls for parties to redefine themselves in light of 1990 and 2006 lessons.)
  • Rule of Law and Accountability
    • Strong demands exist for independent investigations into the use of excessive force and arson during protests.
    • The credibility of Nepal’s democracy depends on whether security forces and political elites are held accountable.
    • Sushila Karki’s pledge to investigate abuses and compensate victims sets both a legal and moral benchmark.
  • Economic and Social Policy Pressure
    • With youth unemployment at 20%, migration pressures, and widening inequality, socio-economic grievances remain central.
    • The interim government faces urgent pressure to deliver short-term relief (jobs, anti-corruption crackdowns) while laying the groundwork for structural reforms in education, employment, and inclusivity.
    • Failure to deliver may reignite unrest and deepen distrust in democratic institutions.

Implications for South Asia (regional)

  • Contagion Risk and Inspiration:
    • The Nepali uprising reflects a wider Gen-Z dissent pattern in Asia.
    • Similar youth-led movements in Sri Lanka (2022), Bangladesh, Indonesia, Philippines have challenged entrenched elites.
    • Nepal’s protests may inspire emulation across borders, intensifying regional instability.
  • Cross-Border Diplomacy & Stability:
    • Political turbulence in Kathmandu could strain bilateral relations with neighbours.
    • Instability may disrupt migration flows, remittances, and border trade.
    • Governments in South Asia may reassess youth policy, unemployment measures, and digital freedoms to preempt unrest.
  • Policy Lessons on Digital Platforms:
    • Nepal’s ban highlights the risks of hard regulation of social media.
    • Neighbouring states will closely observe whether bans quell dissent or provoke backlash.
    • The episode may shape future regional digital governance frameworks balancing free expression with misinformation control.

Conclusion

Nepal’s Gen Z uprising is both tragic and transformative. It highlights the power of digital natives to hold governments accountable, but also the dangers of violence and misinformation. The coming months will test whether Nepal can channel this energy into transparent, inclusive governance or relapse into instability.

PYQ Linkage:

[UPSC 2012] Discuss the contentious issues that have caused the prolonged

constitutional logjam in Nepal.

Linkage: The 2025 Gen Z protests in Nepal show that unresolved constitutional questions of inclusiveness, accountability, and representation remain central even after the 2015 Constitution. The uprising exposed youth anger at elite capture and exclusion of caste, ethnic, and gender groups — echoing the very fault lines that prolonged Nepal’s constitutional logjam post-2008 monarchy abolition. Thus, the recent turmoil is a continuation of the older struggle for a truly inclusive and accountable Nepali state.

Supreme Court cites Preamble to reject a plea

Why in the News?

The Supreme Court rejected a plea against a religious leader inaugurating Mysuru Dasara, reminding that the Preamble upholds secularism, liberty, equality, and fraternity as core ideals of unity.

Backgrounder:

  • The Karnataka government invited Banu Mushtaq, 2025 International Booker Prize winner, to inaugurate Mysuru Dasara Festival and perform the pooja.
  • A 2023 video resurfaced where she questioned the worship of Goddess Bhuvaneshwari, sparking controversy.
  • BJP and others opposed the invite, for her selective criticism of Hindu rituals and demanded withdrawal of the invite sent to her.

Supreme Court’s Observations:

  • Secular Character: The Court reminded that the Preamble enshrines secularism, liberty, equality, and fraternity as unifying ideals.
  • State’s Neutrality: Dasara inauguration was a State event, not a private ritual. The State ā€œmaintains no religion of its ownā€ (echoing M. Ismail Faruqui, 1994).
  • Key Precedents Recalled:
    • Kesavananda Bharati (1973) & S.R. Bommai (1994): Secularism = basic feature of the Constitution.
    • R.C. Poudyal (1994): Even before ā€œsecularā€ was inserted (42nd Amendment, 1976), the Constitution upheld equal treatment of all faiths.
    • Dr. Balram Singh v. UOI (2024): State can intervene to curb religious practices impeding equality & development.

Preamble

About the Preamble:

  • Nature: Introductory statement; reflects philosophy, vision, and objectives.
  • Origin: Based on Objectives Resolution (Nehru, 1946); adopted 1947.
  • Declarations: India as Sovereign, Socialist, Secular, Democratic, Republic ensuring Justice, Liberty, Equality, Fraternity.
  • Symbolism:

    1. Source of Authority: ā€œWe, the People of India.ā€
    2. Nature of State: Sovereign, Socialist, Secular, Democratic, Republic.

  • Only Amendment: 42nd Constitutional Amendment Act, 1976 (during Emergency).
    • Added ā€œSocialistā€ and ā€œSecularā€ between Sovereign and Democratic.
    • Added ā€œIntegrityā€ to Unity of the Nation.

Key Judicial Pronouncements:

  • Berubari Union Case (1960): Preamble not a part of the Constitution; only a tool for interpretation.
  • Kesavananda Bharati Case (1973): Overruled Berubari; Preamble is part of the Constitution, embodies basic structure but cannot override provisions.
  • S.R. Bommai Case (1994): Secularism upheld as basic feature of the Constitution.
  • LIC of India Case (1995): Reaffirmed Preamble as integral, but non-justiciable (not enforceable in court).
[UPSC 2020] The Preamble to the Constitution of India is:

Options: (a) a part of the Constitution but has no legal effect

The Election Commission de-listed 474 Registered Unrecognised Political Parties (RUPP) for not contesting polls in six years, as part of its electoral clean-up drive.

Delisting of Political Parties:

  • ECI’s Powers: Governed by Section 29A, RP Act, 1951.
    • No explicit power with ECI to de-register a party once registered, except for fraud or anti-Constitutional allegiance.
  • Judicial Interpretation:
    • INC vs Institute of Social Welfare (2002): SC ruled that ECI cannot de-register parties, only delist or declare inactive, which removes privileges but NOT their legal entity.

About Registered Unrecognised Political Parties (RUPPs):

  • Constitutional Right: Right to form political associations is guaranteed under Article 19(1)(c).
  • Registration: RUPPs are political associations registered with the Election Commission of India (ECI) under Section 29A, Representation of the People Act, 1951.

Food Procurement and Distribution – PDS & NFSA, Shanta Kumar Committee, FCI restructuring, Buffer stock, etc.

[19th Septmeber 2025] The Hindu Op-ed: Equalising Primary Food Consumption in India

PYQ Relevance

[UPSC 2019] What are the reformative steps taken by the Government to make food grain distribution system more effective?

Linkage: The article’s proposal to restructure the PDS by trimming excess cereal entitlements and expanding pulse distribution directly links with UPSC 2019’s question. It highlights how reformative steps—like targeted subsidies, rationalised stocking by FCI, and focus on nutritional security beyond cereals—can make the food grain distribution system more effective. Thus, it connects poverty reduction with sustainable and equitable food security reforms.

Mentor’s Comment

The recent NSS household consumption survey, coupled with World Bank estimates, has painted a contrasting picture of India’s poverty and food deprivation. While global narratives celebrate the near-eradication of extreme poverty, ground-level consumption data tells a more sobering story, half of rural India still struggles to afford two simple thalis a day. This article unpacks the deeper meaning of food security beyond calorie intake, critiques the existing Public Distribution System (PDS), and explores how restructuring subsidies, especially towards pulses, can equalise food consumption in India. For UPSC aspirants, the debate is not only about statistics but also about welfare priorities, distributional justice, and the role of the state in ensuring dignified living standards.

Introduction

India has long battled poverty and hunger, but the release of the 2024 NSS Household Consumption Survey and the World Bank’s Poverty and Equity Brief (2025) has reshaped the debate. The World Bank report claims that extreme poverty has fallen from 16.2% in 2011-12 to just 2.3% in 2022-23, a historic achievement if true. Yet, when food consumption is measured through the ā€œthali indexā€ rather than calorie-based poverty lines, stark disparities emerge: 50% of rural India and 20% of urban India could not afford two thalis a day in 2023-24. This contradiction raises a crucial policy question—how can India ensure not just calorie intake but nutritional adequacy and equal access to primary food consumption?

The contrasting narratives of poverty in India

  1. World Bank Estimate: Extreme poverty has ā€œvirtually disappeared,ā€ with only 2.3% living below $2.15/day.
  2. Thali Index Reality: Despite rising incomes, half of rural India could not afford two balanced meals (thalis) daily in 2023-24.
  3. Deprivation Gap: The difference arises because food is residual expenditure after households spend on essentials like rent, health, and transport.

Why measure poverty through the thali meal?

  1. Beyond Calories: Traditional poverty lines only measure calorific intake, ignoring nutrition and satisfaction.
  2. Balanced Meal: A thali (rice, dal, roti, vegetables, curd, salad) represents a self-contained, nutritious unit of food consumption.
  3. Cost Factor: Crisil estimates a home-cooked thali costs ₹30. Many households fall short of affording even two thalis/day per person.

How effective is the Public Distribution System?

  1. Food Deprivation with PDS: Even after including PDS food supplies, deprivation persists—40% rural and 10% urban cannot afford two thalis daily.
  2. Subsidy Distribution: In rural India, a person in the 90–95% expenditure class receives 88% of the subsidy given to the poorest 5%, despite much higher consumption capacity.
  3. Urban Progressivity: The PDS is more progressive in urban areas, but still, 80% receive subsidised or free food, including those not in need.

Why are cereals not enough

  1. Equalised Cereal Consumption: Both the poorest and richest consume similar amounts of rice and wheat, showing PDS success but also its limits.
  2. Expenditure Share: Cereals now account for only 10% of average household expenditure, so increasing cereal subsidy has diminishing returns.
  3. Need for Protein: Pulses consumption is half in the poorest 5% compared to the richest 5%, highlighting protein inequality.

Policy path: Equalising food consumption through pulses

  1. Expand PDS Coverage: Redirect subsidies towards pulses, the main protein source for many Indians.
  2. Rationalise Cereals Subsidy: Trim excess rice/wheat entitlements, especially for better-off groups, reducing stocking costs for FCI.
  3. Compact and Targeted PDS: By focusing on pulses and eliminating subsidies beyond the ā€œtwo thali/dayā€ norm, the system becomes both cost-effective and equitable.
  4. Global Significance: Achieving equalised food consumption across social classes would be a unique welfare success story worldwide.

Conclusion

The thali index reveals a hidden crisis of food deprivation that headline poverty numbers obscure. While cereal consumption has been equalised through decades of PDS efforts, the next frontier lies in ensuring protein security via pulses distribution. Rationalising subsidies and targeting them effectively can not only optimise public spending but also equalise primary food consumption across India, a feat that would stand as a benchmark in global welfare policy.

Artificial Intelligence (AI) Breakthrough

How the DeepSeek-R1 AI model was taught to teach itself to reason

Introduction

Reasoning, the ability to reflect, verify, self-correct, and adapt, has historically been considered uniquely human. From mathematics to moral decision-making, reasoning shapes every facet of human civilisation. Large language models (LLMs) like GPT-4 have shown glimpses of reasoning, but these were achieved with human-provided examples, introducing cost, bias, and limits. In September 2024, researchers at DeepSeek unveiled their model R1, which demonstrated reasoning through reinforcement learning (trial and error with rewards), without supervised fine-tuning. This represents a paradigm shift in how machines may learn, reason, and potentially evolve intelligence.

Why is DeepSeek-R1 in the News?

For the first time, an AI model has taught itself to reason without human-crafted examples. The results were dramatic: DeepSeek-R1 improved from 15.6% to 86.7% accuracy in solving American Invitational Mathematics Examination (AIME) problems, even surpassing the average performance of top human students. It also demonstrated reflection (ā€œwait… let’s try againā€) and verification—human-like traits of reasoning. The scale and quality of progress mark this as a milestone in AI research, contrasting sharply with traditional methods that heavily relied on human-labelled data.

What is Reinforcement Learning in AI?

  1. Definition: Reinforcement learning (RL) is a trial-and-error method where a system receives rewards for correct answers and penalties for wrong ones.
  2. DeepSeek’s Application: Instead of providing reasoning steps, the model was only rewarded for correct final answers.
  3. Outcome: Over time, R1 developed reflective chains of reasoning, dynamically adjusting ā€œthinking timeā€ based on task complexity.

How Did DeepSeek-R1 Achieve Self-Reasoning?

  1. R1-Zero Phase: Started with solving maths/coding problems, producing reasoning inside <think> tags and answers in <answer> tags.
  2. Trial-and-Error Learning: Wrong reasoning paths were discouraged, correct ones reinforced.
  3. Emergence of Reflection: Model started using ā€œwaitā€ or ā€œlet’s try again,ā€ indicating self-correction.

What Were the Major Successes?

  1. Mathematical Benchmarks: R1-Zero improved from 15.6% to 77.9%, and with fine-tuning, to 86.7% on AIME.
  2. General Knowledge & Instruction Following: 25% improvement on AlpacaEval 2.0 and 17% on Arena-Hard.
  3. Efficiency: Adaptive thinking chains—shorter for easy tasks, longer for difficult ones—conserving computational resources.
  4. Alignment: Improved readability, language consistency, and safety.

What Are the Limitations and Risks

  1. High Energy Costs: Reinforcement learning is computationally expensive.
  2. Human Role Not Fully Eliminated: Open-ended tasks (e.g., writing) still require human-labelled data for reward models.
  3. Ethical Concerns: Ability to ā€œreflectā€ raises risks of generating manipulative or unsafe content.
  4. Need for Stronger Safeguards: As AI reasoning grows, so does the risk of misuse.

Why Does this Matter for the Future of AI?

  1. Reduces Dependence on Human Labour: Cuts costs and addresses exploitative conditions in data annotation.
  2. Potential for Creativity: If reasoning can emerge from incentives, could creativity and understanding follow?
  3. Shift in AI Training Paradigm: From ā€œlearning by exampleā€ to ā€œlearning by exploration.ā€
  4. Global Implications: Impacts education, coding, mathematics, governance, and ethics of AI.

Conclusion

DeepSeek-R1 marks a turning point in AI evolution. By demonstrating reasoning through reinforcement learning alone, it challenges the notion that human-labelled data is indispensable. Yet, this very capability opens new debates—about creativity, autonomy, and control. For policymakers and citizens alike, the task is to harness AI’s promise while ensuring safety, fairness, and ethical integrity.

PYQ Relevance:

[UPSC 2023] Introduce the concept of Artificial Intelligence (AI). How does Al help clinical diagnosis? Do you perceive any threat to privacy of the individual in the use of Al in healthcare?

Linkage: The breakthrough of DeepSeek-R1 shows how AI can now reason through reinforcement learning without human-labelled data, making it more efficient and adaptive. Such reasoning ability can enhance clinical diagnosis by enabling AI to self-correct and refine decision-making in complex medical cases. However, as with healthcare AI generally, the privacy threat persists if sensitive patient data is fed into models without strong safeguards.

Foreign Policy Watch: India-China

Should India overlook boundary issues while normalizing ties with China?

Introduction

The India-China relationship has historically oscillated between cautious cooperation and sharp confrontation. The latest Modi–Xi meeting on the sidelines of the SCO Summit reopened bilateral trade, air connectivity, and emphasised peace at the border. Yet, the memory of the 2020 Galwan clashes looms large. At stake is the central question: Can India afford to set aside the boundary dispute for the sake of wider cooperation, or would that compromise its strategic autonomy and long-term security?

Why is this debate in the news?

Prime Minister Narendra Modi’s China visit marks the first high-level attempt in five years to restore normalcy after Galwan. The move is significant as it reflects India’s willingness to restart engagement despite recent military tensions and China’s continued strategic partnership with Pakistan. The revival of trade and connectivity signals pragmatism, but it raises the question of whether unresolved boundary tensions can remain compartmentalised. This sharp contrast with the hostility of recent years makes the issue both urgent and unprecedented.

Can India normalise ties without resolving the boundary issue?

  1. Historical Precedent (1988, 1990s): Rajiv Gandhi’s visit to Beijing in 1988 initiated the idea of cooperation in other domains while border talks continued separately. Both sides agreed to maintain peace and tranquility along the LAC despite unresolved sovereignty disputes.
  2. Galwan Disruption (2020): The deadly clash exposed the fragility of this arrangement and highlighted China’s aggressive posture, a setback far greater than earlier skirmishes.
  3. Current Diplomatic Push: Since 2020, both countries have restored disengagement through buffer zones, with the 2024 Border Patrol Agreement marking an important breakthrough, including restoration of patrol rights in Demchok and Depsang.

What explains China’s actions and insecurities?

  1. Article 370 Effect: Chinese analysts linked Galwan to India’s constitutional move in Jammu & Kashmir, which Beijing opposed.
  2. Economic Competition: During the U.S.-China trade war, Beijing feared India aligning with Washington to grab supply-chain opportunities.
  3. India’s Growth Factor: China increasingly perceives India’s demographic dividend and economic rise as a potential threat, at a time when its own population is shrinking.
  4. Manufacturing Prowess: Despite insecurities, China’s dominance is overwhelming—accounting for 45% of global manufacturing output, highlighted by India’s Economic Survey 2024-25.

How fragile is the current normalisation?

  1. Possibility of Galwan-2: Any fresh military clash could derail progress entirely, as mistrust remains deep-rooted.
  2. Chinese Perception of India: Beijing no longer treats India as a peer but as a regional player to be managed, often subordinated to its ties with Pakistan.
  3. Infrastructure Build-up: China continues rapid military expansion on the Tibetan plateau, forcing India to invest heavily in its own LAC infrastructure.
  4. Diplomatic Asymmetry: Even as dialogue continues, China shows little real interest in a final border settlement.

Can India-China cooperation coexist with China’s South Asia strategy?

  1. China’s Trilateral Mechanisms: Beijing is building frameworks like Pakistan-China-Afghanistan and Pakistan-China-Bangladesh, which aim to sideline India.
  2. Strategic Rivalry: China views India as a long-term competitor; India counters with its own diplomatic cards.
  3. Interdependence Factor: Despite rivalry, both economies remain connected—India dependent on China’s manufacturing, and China wary of India’s market potential.

Conclusion

India cannot afford to overlook the boundary issue entirely, as sovereignty and security form the bedrock of foreign policy. Yet, pragmatic engagement, through trade, connectivity, and multilateral platforms, remains equally important. A calibrated approach that safeguards territorial integrity while leveraging cooperation where possible may be the most realistic path forward.

PYQ Relevance:

[UPSC 2014] With respect to the South China Sea, maritime territorial disputes and rising tension affirm the need for safeguarding maritime security to ensure freedom of navigation and ever flight throughout the region. In this context, discuss the bilateral issues between India and China.

Linkage: The South China Sea tensions highlight China’s assertive behaviour in territorial disputes, which parallels its aggressive stance on the India-China boundary issue, especially after Galwan. Just as freedom of navigation is contested in the maritime domain, peace and tranquility along the LAC is fragile despite agreements like the 2024 Border Patrol pact. Thus, bilateral issues centre on sovereignty, security dilemmas, and China’s attempts to limit India’s strategic space in both continental and regional contexts.

Governor vs. State

[18th September 2025] The Hindu Op-ed: A judicial nudge following stuck legislative business

PYQ Relevance:

UPSC 2022: Discuss the essential conditions for exercise of the legislative powers by the Governor. Discuss the legality of re-promulgation of ordinances by the Governor without placing them before the Legislature.

Linkage: The recent Supreme Court directive fixing a timeline for Governors under Article 200 directly relates to the constitutional limits on gubernatorial powers discussed in the 2022 question. Both highlight that the Governor, as a constitutional head, must act on the aid and advice of the Council of Ministers and not misuse discretion to stall legislation. Just as re-promulgation of ordinances undermines legislative supremacy, withholding assent indefinitely violates constitutional morality and federal balance.

Mentor’s Comment:

The recent Supreme Court intervention fixing a time limit for Governors and the President to act on Bills marks a constitutional milestone. This decision is not merely about timelines but about strengthening federalism, ensuring legislative efficacy, and curbing misuse of gubernatorial discretion. For UPSC aspirants, it becomes a vital case study in Centre-State relations, separation of powers, and the evolving role of the judiciary in sustaining democracy.

Introduction

The Supreme Court’s decision to prescribe a three-month time limit for Governors and the President to take a final call on Bills under Article 200/201 has reignited debates on federalism, separation of powers, and the scope of judicial activism. For decades, Governors have been accused of sitting indefinitely on Bills, creating a legislative deadlock and undermining the democratic will of elected legislatures. This judicial nudge aims to resolve what has become a serious constitutional anomaly, ensuring that governance does not remain hostage to political manoeuvring.

Why is this in the news?

The issue is significant because, for the first time, the Supreme Court has imposed a specific timeline—three months—for Governors and the President to act on Bills, despite the Constitution prescribing none. This intervention arose after repeated instances where Governors withheld assent or simply delayed action on Bills for years, undermining legislative functioning. The decision is both a remedy for constitutional paralysis and a reinforcement of federal balance, making it a landmark moment in India’s constitutional journey.

Judicial clarity on Article 200:

  1. Four options under Article 200: Assent to the Bill, withhold assent, return the Bill for reconsideration, or reserve it for the President.
  2. No discretion intended: The omission of the words ā€œin his discretionā€ (present in Government of India Act, 1935, Section 75) shows the Constituent Assembly wanted Governors to act only on aid and advice of the Council of Ministers.
  3. Judicial commissions’ stand: Both Sarkaria and Punchhi Commissions reiterated that Governors are constitutional heads, not independent power centres.

Has the Governor misused discretionary powers?

  1. Contradictory judicial stance: While Shamsher Singh (1974) acknowledged discretionary scope, later judgments including Nabam Rebia (2016) and Tamil Nadu Governor case (2025) rejected such independence.
  2. Risk of overreach: Allowing Governors unilateral discretion would convert them into ā€œsuper constitutional authorities,ā€ stalling state governance.
  3. Expert view: D.D. Basu highlighted that unlike UK sovereigns, Indian Governors have no scope for withholding assent independently.

Why did the Supreme Court fix a timeline?

  1. Legislative paralysis: Governors had sat on Bills for years without decision, blocking governance.
  2. Judicial remedy: By fixing three months, the Court ensured smooth functioning of legislatures, akin to how Article 21’s scope was expanded through judicial interpretation in Maneka Gandhi.
  3. Federal protection: Recent rulings in State of Punjab v. Governor (2023) and State of Tamil Nadu v. Governor (2025) strengthened states’ autonomy, preventing misuse of gubernatorial office.

Could the Union have intervened earlier?

  1. Role under Article 355: The Union is duty-bound to ensure constitutional governance in states. A Governor blocking Bills indefinitely amounts to violation of constitutional provisions.
  2. Non-intervention so far: Successive Union governments avoided directing Governors, leading to judicial stepping in.
  3. Judicial nudge as necessity: The Court’s ruling acts as a constitutional guardrail in absence of executive remedy.

Implications for federalism and democracy

  1. Strengthening federal balance: Prevents Governors from acting as political agents of the Centre.
  2. Judicial activism or necessity?: Critics see it as judicial overreach, but history shows courts often expand constitutional meaning to meet new realities (e.g., Article 21 due process).
  3. Legislative efficiency: Restores faith in elected assemblies’ authority, ensuring people’s mandate is not subverted.

Conclusion

The Supreme Court’s directive to Governors and the President is a pragmatic response to a constitutional vacuum. It plugs misuse, safeguards federalism, and ensures legislative efficiency. Far from amending the Constitution, it exemplifies how judicial interpretation adapts constitutional principles to emerging challenges. This marks a significant moment where judicial innovation has strengthened democracy by preventing paralysis of governance.
