Voter ID as the Basis for Welfare Delivery: Identity, Entitlement and the Risk of Double Exclusion

Core TopicGS-II · Governance — Welfare Schemes, Mechanisms for Protection of Vulnerable SectionsPrelims + MainsThe Hindu

On 3 November 2026, the Union Minister for Panchayati Raj announced that voter ID cards (EPIC), combined with biometric authentication, would replace Aadhaar for identifying beneficiaries and processing welfare payments. The stated reason was that Aadhaar is prone to fraudulent enrolment. After pushback, he clarified on 6 November that EPIC would be used alongside Aadhaar and that no rightful beneficiary would be excluded.

◈ From the Basics — Identity Documents vs Entitlement Documents

Welfare delivery involves three steps: identifying who a person is, verifying that they are eligible, and paying them. An identity document (such as Aadhaar or EPIC) proves who you are. An entitlement document (such as a ration card or job card) proves what you are owed.

• EPIC (Electors Photo Identity Card): issued by the Election Commission of India (ECI) since 1993 to persons on the electoral roll. Eligibility requires Indian citizenship and an age of 18+ (Article 326; Representation of the People Act, 1950). EPIC carries no biometric data.
• Aadhaar: a 12-digit number issued by UIDAI under the Aadhaar Act, 2016 to residents (citizenship is not required) and linked to biometrics. Section 7 allows it to be required for subsidies and benefits paid from the Consolidated Fund of India.
• Puttaswamy (Aadhaar) judgment, 2018: a five-judge Bench upheld Section 7, holding that welfare delivery is a legitimate State aim. It struck down private-sector use of Aadhaar (Section 57).
• EPIC–Aadhaar linkage: the Election Laws (Amendment) Act, 2021 permitted voluntary linking of the two.

Have Voter IDs Been Used for Welfare Before?

• As an entry document: commonly called pehchaan patra, EPIC has long been one of the accepted documents for obtaining other entitlements, such as the MGNREGA job card.
• State-level use: some States, such as Delhi, require EPIC for certain pension schemes, and enrolment needs endorsement by the local councillor or legislator.
• Never the sole basis nationally: EPIC has not so far been the exclusive identifier for welfare delivery anywhere in India.
• Family cards: starting with Madhya Pradesh and Rajasthan, 10 States have introduced family cards. These recognise that many schemes target households, not individuals.
• West Bengal: on 4 June 2026, the State’s Food and Supplies Department issued an order linking State-run welfare schemes, including PDS ration cards, to the electoral rolls.

The two documents were built for different purposes. Using a franchise document as a welfare key ties entitlement to electoral-roll status.

The Concerns

• Link with the SIR: Opposition parties connect the proposal to the Special Intensive Revision (SIR) of electoral rolls, during which more than 13 crore electors have reportedly been removed. Their concern is that disenfranchisement could be followed by exclusion from welfare.
• Pending appeals: civil society group Mazdoor Kisan Shakti Sangathan (MKSS) points out that in West Bengal, 22 lakh people appealed against deletion from the rolls and about 21 lakh still await tribunal decisions.
• “Two-level exclusion”: first from the vote, then from benefits. Voting is a political right, while food, pension and work entitlements flow from socio-economic rights (Article 21, read with DPSPs, Articles 39, 41 and 47).
• Purpose mismatch: Aadhaar works as a “financial address” because it is linked to bank accounts through DBT. EPIC adds no payment function.
• Groups who may lack a valid EPIC: those under 18 (relevant for child-focused schemes), internal migrants registered elsewhere, and people whose names were wrongly deleted.
• Portability: schemes such as One Nation One Ration Card rely on Aadhaar-based portability. A roll-based key, tied to a constituency, may undermine this.

▤ The Ministry’s Role & Key Numbers

• The Ministry of Panchayati Raj does not run individual-beneficiary schemes. It works through gram sabhas, and so indirectly shapes rural welfare delivery.
• Sixteenth Finance Commission (award period 2026–31): grants of ₹4,35,236 crore recommended for 2.55 lakh panchayats and traditional local bodies. Their distribution lies within the Ministry’s domain.
• The Government has not yet clarified whether the proposed identification formula will extend to all welfare schemes.

The Other Side of the Debate

• Leakage is real: fake and duplicate beneficiaries drain public money. Verifying identity through more than one source can improve targeting.
• Aadhaar’s own limits: Aadhaar does not establish citizenship, and enrolment-integrity issues have been reported. This is the stated rationale for an additional check.
• The revised position (EPIC together with Aadhaar) is a narrower measure than outright replacement.

Way Forward

• Follow the Puttaswamy standard: any new identity requirement should pass the tests of legality, legitimate aim, proportionality and procedural safeguards.
• Do not deny benefits to people whose roll deletion is under appeal, and keep alternative documents as fall-backs, as the NFSA and MGNREGA frameworks already permit.
• Use social audits and gram sabha verification for targeting, rather than a single-document gate.
• Wider adoption of family cards could reflect household-based entitlements more accurately.

Punjab Reopens Ravi–Beas and Yamuna Water Disputes: Five Assembly Resolutions and Their Legal Limits

Core TopicGS-II · Federalism — Inter-State Relations, Water DisputesGS-I · Geography — River SystemsPrelims + MainsThe Indian Express

As Punjab marks 60 years since its reorganisation (1 November 1966), its Assembly passed five resolutions on 27 October 2026 to reopen water-sharing arrangements. The resolutions followed a 7 September assurance by the State government to protesting farmers.

◈ From the Basics — How the Constitution Handles River Waters

• Entry 17, State List: water (supply, irrigation, canals, drainage, storage) is a State subject. It is subject to Entry 56, Union List, which covers the regulation and development of inter-State rivers where Parliament declares it to be in the public interest.
• Article 262: Parliament may provide for adjudication of inter-State water disputes and may bar the jurisdiction of the Supreme Court and other courts over them.
• Inter-State River Water Disputes Act, 1956: provides for tribunals whose awards have the force of a Supreme Court decree. Under Section 7, a State cannot levy a seigniorage, fee or rate on another State merely because river works lie in its territory.
• Riparian principle vs equitable apportionment: Punjab argues that, as the riparian State (the one the rivers flow through), it should control the waters. Indian adjudication generally follows equitable apportionment, which weighs need, basin area, past use and alternative sources.
• Indus Waters Treaty (1960): gave India the eastern rivers (Sutlej, Beas, Ravi) and Pakistan the western rivers (Indus, Jhelum, Chenab). India placed the Treaty in abeyance in April 2025.

▤ The Five Resolutions (27 October 2026)

• An equitable share in Yamuna waters.
• ₹1.44 lakh crore in royalty from Rajasthan for use of Sutlej, Ravi and Beas waters.
• Control over key headworks.
• Repeal of the Dam Safety Act, 2021.
• Projects to use Ravi waters currently flowing to Pakistan.
• Separately, the State has sought review or repeal of Sections 78, 79 and 80 of the Punjab Reorganisation Act, 1966.

Timeline — How the Dispute Unfolded

• January 1955: 15.85 MAF of surplus Ravi–Beas water was allocated: Rajasthan 8, undivided Punjab (including PEPSU) 7.2, and J&K 0.65. According to the experts cited, Rajasthan’s large share was meant to demonstrate India’s use of the eastern rivers ahead of the Indus Waters Treaty talks.
• 1966: Haryana was created. Section 78 gave the States two years to agree on sharing, failing which the Centre would decide. Sections 79–80 dealt with the Bhakra Management Board (now the Bhakra Beas Management Board) and the Beas Project.
• 1976 Central order: 3.5 MAF each to Punjab and Haryana, and 0.08 MAF to Delhi.
• 1981 Tripartite Agreement (Punjab, Haryana, Rajasthan): 17.17 MAF was re-divided, and the Sutlej–Yamuna Link (SYL) canal was to carry Haryana’s share. The agreement was opposed by the Nehar Roko Morcha at Kapuri (1982), which later became part of the Dharam Yudh Morcha.
• Punjab Accord (1985) → Eradi Tribunal (April 1986), headed by former Supreme Court judge V. Balakrishna Eradi. Its January 1987 report raised Punjab’s share to 5 MAF and Haryana’s to 3.83 MAF. The SYL canal remains unfinished.
• 2004: Punjab enacted the Punjab Termination of Agreements Act. In its Presidential Reference opinion (10 November 2016) under Article 143, the Supreme Court held the Act unconstitutional: a State cannot unilaterally end an inter-State agreement or nullify the Court’s SYL decree.

Figure 1 — Ravi–Beas Allocations Over Time (MAF)

PunjabHaryanaRajasthan024687.2*8.019553.53.51976 order4.223.58.61981 accord5.03.838.6Eradi 1987* Undivided Punjab incl. PEPSU, before Haryana’s creation. J&K (0.65) and Delhi allocations not shown.

Rajasthan’s allocation has remained the largest throughout. Punjab’s share rose only under the Eradi Tribunal, whose report has not been implemented in full.

How Far Can Punjab’s Claims Go?

• Repealing Sections 78–80: the Punjab Reorganisation Act is a Central law. Punjab can only ask Parliament to amend it, or challenge it in court on constitutional grounds. An Assembly resolution has no binding force. Experts note that even the 2004 law was struck down.
• Royalty from Rajasthan: the claim rests on a 1920 arrangement under which the princely state of Bikaner paid for Sutlej water carried by the Gang (Bikaner) Canal from the Ferozepur headworks. However, Section 7 of the 1956 Act bars such levies, and no constitutional provision allows inter-State royalty. The claim is therefore legally weak.
• Yamuna share: Punjab argues that the Yamuna flowed through undivided Punjab, citing a 12 March 1954 agreement with Uttar Pradesh and the 1972 Irrigation Commission. It was not a signatory to the 12 May 1994 Yamuna MoU among the basin States. Haryana now draws nearly 6 MAF of Yamuna water. In April 2025, Punjab asked the Jal Shakti Ministry for a tribunal. Experts quoted consider this claim the more tenable one.
• Basin-share argument: Punjab holds 16% of India’s Indus drainage area, against 3% for Haryana and 5% for Rajasthan, but its allocation does not reflect this.
• Ravi flows to Pakistan: the Shahpur Kandi dam (completed 2024) and the planned Ujh project aim to retain eastern-river water within India.

The Federal Dimension

• Dam Safety Act, 2021: enacted under Entry 56, the Act creates national and State dam-safety authorities. Punjab views it as Central intrusion into a State subject.
• Water and identity: river water has been tied to agrarian distress and regional identity in Punjab since the 1980s. Groundwater depletion (most of Punjab’s blocks are over-exploited) raises the stakes further.
• Structural weaknesses: tribunal delays, non-implementation of awards, and the lack of a permanent dispute-resolution mechanism. The Inter-State River Water Disputes (Amendment) Bill, 2019, which proposed a single permanent tribunal, has not been enacted.

Way Forward

• Seek a fresh assessment of water availability: flows have changed since the 1950s estimates.
• Pursue negotiated settlement through the Centre and Zonal Councils, alongside time-bound tribunal adjudication.
• Pair any reallocation with demand-side reform: crop diversification away from paddy, and micro-irrigation.

Ten Years After Demonetisation: Digital Payments Have Boomed, but Cash Has Returned to Pre-2016 Levels

Core TopicGS-III · Economy — Money & Banking, Monetary Policy, FormalisationPrelims + MainsThe Indian Express

A decade after the 8 November 2016 withdrawal of ₹500 and ₹1,000 notes, currency with the public stands at ₹42.55 lakh crore (15 October 2026). This is about 137% above its pre-demonetisation level, and the currency-to-GDP ratio is back near where it was in 2016.

◈ From the Basics — Demonetisation and Money Measures

Demonetisation means withdrawing the legal-tender status of a currency unit. Legal tender is money that must be accepted in settlement of a debt. In 2016, this was done by a Government notification under Section 26(2) of the RBI Act, 1934, on the recommendation of the RBI’s Central Board.

• Currency in Circulation (CIC): all notes and coins issued by the RBI.
• Currency with the public: CIC minus cash held by banks. This is the measure of cash actually in people’s hands.
• CIC-to-GDP ratio: currency relative to the size of the economy. It is a better gauge of cash dependence than absolute values, which naturally rise with nominal GDP.
• Earlier demonetisations: 1946 (₹1,000 and ₹10,000 notes) and 1978 (₹1,000, ₹5,000 and ₹10,000), the latter under the High Denomination Bank Notes (Demonetisation) Act, 1978.
• Legal closure: the Specified Bank Notes (Cessation of Liabilities) Act, 2017 ended the RBI’s liability on the old notes. In Vivek Narayan Sharma v. Union of India (January 2023), the Supreme Court upheld the decision by a 4:1 majority.

What Happened in 2016

• The demonetised notes made up about 86% of the currency in circulation, which caused a severe cash crunch for households, traders and the informal sector.
• Stated objectives: curbing black money, counterfeit currency and terror financing, and later, promoting digital payments, formalisation and a less-cash economy.
• Immediate effects: currency with the public fell from ₹17.97 lakh crore (4 Nov 2016) to ₹7.8 lakh crore (January 2017). Demand slumped, and GDP growth fell by nearly 1.5 percentage points.
• Returns: the RBI later reported that about 99.3% of the demonetised value had come back to banks, which weakened the black-money rationale.
• Remonetisation: new ₹500 and ₹2,000 notes were issued. The ₹2,000 note was withdrawn from circulation in 2023.

Figure 1 — India’s Currency-in-Circulation to GDP Ratio (%)

The ratio fell sharply in 2016-17, peaked at 14.4% during the pandemic, and stood at 12.1% in FY26, almost the same as March 2016 (12.2%).

▤ The Numbers

• Currency with the public: ₹17.97 lakh crore (Nov 2016) → ₹42.55 lakh crore (Oct 2026). In calendar year 2026 (to 16 October), it rose by ₹5.26 lakh crore, or 14.1%.
• CIC/GDP: 12.2% (March 2016) → 8.7% (2016-17) → 14.4% (2020-21) → 12.1% (FY26).
• International comparison: above 16% in Japan, 10.2% in China, and 7.3% in the US, where the dollar also circulates abroad.
• GDP growth: the economy has grown at 6–7% in several years, touching 7.8% in a recent quarter.

Why Cash Persists Despite the Digital Boom

• Digital and cash are complements: UPI (launched by NPCI in 2016) now dominates payment volumes, but cash remains the main store of value for many households.
• Precautionary demand: shocks such as the COVID-19 lockdown push people to hold cash.
• Informality: a large informal sector, and rural and elderly users with limited digital access, keep cash in use.
• Low opportunity cost: in periods of lower interest rates, holding cash costs less in forgone interest.
• Trust and privacy: concerns about digital fraud and transaction traceability sustain the preference for cash.

Assessment — Gains and Costs

• Gains claimed: a sharp rise in digital payments, wider tax-base expansion, and a push to formalisation. It is debated how much of this was due to demonetisation itself, as opposed to GST (2017), JAM and smartphone diffusion.
• Costs: output and job losses in the informal sector, an MSME liquidity stress, and the expense of printing new currency.
• Black money: nearly all the money came back to banks. This suggests that illicit wealth was largely held in non-cash assets (property, gold, offshore holdings).
• Policy lesson: behavioural change in payments comes from convenience and trust rather than from shock withdrawal of cash.

‘VAJRA-SAT’: India’s First National Tabletop Exercise on Foot-and-Mouth Disease Serotype SAT-1

ImportantGS-III · Agriculture — Animal Husbandry, Livestock Economy; Disaster PreparednessPrelims + MainsPIB · Ministry of Fisheries, Animal Husbandry & Dairying

The Department of Animal Husbandry and Dairying (DAHD) and ICAR-NIVEDI, Bengaluru, held a two-day national tabletop exercise, ‘VAJRA-SAT’, on 4–5 November 2026. The exercise prepared for FMD serotype SAT-1, which has never been reported in India, but which has spread from Africa to parts of West Asia.

◈ From the Basics — Foot-and-Mouth Disease

• FMD is a highly contagious viral disease of cloven-hoofed animals (cattle, buffalo, sheep, goats, pigs). It is caused by an Aphthovirus of the family Picornaviridae.
• Symptoms: fever, and blisters in the mouth and on the feet and teats, leading to a sharp fall in milk yield and draught power. Mortality in adult animals is low, but economic losses are high. FMD is not a public-health threat to humans.
• Seven serotypes: O, A, C, Asia-1, SAT-1, SAT-2, SAT-3 (“SAT” stands for Southern African Territories). Immunity to one serotype does not protect against another, so a new serotype would need a new vaccine strain.
• In India, serotypes O, A and Asia-1 are prevalent. The vaccines under the national programme target these.
• Transboundary animal disease: FMD is listed by WOAH (World Organisation for Animal Health, formerly OIE), which grants FMD-free status to countries, zones or compartments.

▤ The Exercise at a Glance

• Theme: “Detect Early, Confirm Fast, Contain Together”.
• Participants: 83 from 25 States, 3 UTs and national institutions: State animal husbandry departments, ICAR institutes, diagnostic labs, veterinary universities, vaccine makers, and defence and border-guarding agencies. The National Security Council Secretariat was also represented.
• Simulated scenarios: early detection, laboratory confirmation, epidemiological investigation, animal movement control, emergency vaccination, and risk communication.
• Technical meeting (5 Nov): on FMD-free compartmentalisation of semen stations and semen banks, to protect elite genetics and enable safe livestock trade.
• Key institutions: ICAR-NIVEDI (Bengaluru; disease epidemiology and informatics); ICAR-NIFMD (Bhubaneswar; the national FMD reference lab); Regional Disease Diagnostic Laboratories.

Why It Matters

• Livestock economy: India is the world’s largest milk producer, and livestock supports the livelihoods of crores of small and marginal farmers. FMD is among the costliest livestock diseases.
• Trade: FMD status determines access to meat and dairy export markets. Compartmentalisation lets FMD-free units trade even when the country as a whole is not free of the disease.
• Biosecurity and borders: the involvement of the NSCS and border agencies reflects the treatment of animal disease as a national-security and One Health issue.
• Ongoing programme: the National Animal Disease Control Programme (NADCP, 2019) provides free mass vaccination against FMD and brucellosis, with the goal of controlling FMD through vaccination and eventually eradicating it. A new serotype would test this programme.

Gaps to Address

• Build SAT-1 diagnostic capacity and a vaccine bank (antigen reserve) before any incursion.
• Address weak animal movement tracking. The INAPH/Bharat Pashudhan ear-tag database can support this.
• Strengthen veterinary manpower and timely reporting at the village level.

Samudrayaan: India Targets Its First Crewed Dive to 6,000 Metres by 2028 Under the Deep Ocean Mission

ImportantGS-III · S&T — Indigenisation of Technology; Blue EconomyPrelims + MainsThe Hindu · PIB

Speaking at the Indo-Pacific Regional Dialogue (IPRD) 2026, the Union Minister of State (Independent Charge) for Science & Technology and Earth Sciences said India aims to send its first human deep-sea mission to a depth of up to 6,000 m by 2028, using the Matsya submersible.

◈ From the Basics — Why the Deep Ocean?

The deep sea (below about 1,000 m, where no sunlight reaches) holds mineral deposits, unique biodiversity and energy potential. Only a handful of countries can send humans there, because the pressure at 6,000 m is about 600 times that at the surface.

• Polymetallic nodules: potato-sized lumps on the abyssal seabed rich in manganese, nickel, cobalt and copper, which are critical for batteries.
• Hydrothermal (polymetallic) sulphides: deposits formed near volcanic vents on mid-ocean ridges, rich in copper, zinc, gold and silver.
• International Seabed Authority (ISA): set up under UNCLOS (1982) and headquartered in Kingston, Jamaica. It regulates mining in “the Area” (the seabed beyond national jurisdiction), which UNCLOS treats as the common heritage of mankind.
• India’s ISA contracts: India was the first country to receive Pioneer Investor status (1987), for nodules in the Central Indian Ocean Basin (CIOB). It also holds a contract for polymetallic sulphides on the Indian Ocean ridges.

▤ Mission at a Glance

• Deep Ocean Mission (DOM): approved in 2021, with nodal ministry the Ministry of Earth Sciences (MoES). It is one of the Blue Economy initiatives.
• Samudrayaan is DOM’s crewed-submersible component. Matsya carries three aquanauts to 5,000–6,000 m. It was developed by the National Institute of Ocean Technology (NIOT), Chennai, which can now run trials at these depths in the CIOB.
• Ocean Mineral Explorer: a high-resolution survey system for hydrothermal sulphides, several deposits of which have been identified.
• Other DOM strands: renewable energy from solar, offshore wind and ocean thermal gradients (OTEC); low-temperature thermal desalination (LTTD) in Lakshadweep; and BARC-supported nuclear desalination at Kalpakkam.
• Funding ecosystem: the Anusandhan National Research Foundation (ANRF) and the ₹1 lakh crore Research, Development and Innovation (RDI) Fund, which uses a 50:50 equity-based approach to draw in private capital.

Significance

• Strategic capability: crewed deep-sea dives have so far been achieved by the US, Russia, France, Japan and China. With Matsya, India would join this group. The Government presents this as a deep-sea counterpart to Gaganyaan.
• Critical minerals: secure supplies of cobalt and nickel are needed for the energy transition and electric vehicles.
• Ocean observation and climate: satellite data on ocean colour, sea-surface temperature and winds improves forecasting of cyclones and marine heatwaves for coasts and islands.
• Ocean diplomacy: India proposed joint missions, shared facilities and data-sharing under the principle “One Ocean, Shared Knowledge and Equitable Prosperity”, linked to SAGAR/MAHASAGAR and the Indo-Pacific Oceans Initiative.
• Clean maritime energy: private participation in nuclear power is now enabled under the SHANTI Act, and India targets 100 GW of nuclear capacity by 2047.

Concerns

• Ecological risk: deep-sea mining can destroy slow-recovering habitats. Many countries back a precautionary pause until the ISA Mining Code is finalised.
• Safety: crewed dives at these depths need fail-safe life-support and pressure-hull integrity, and timelines have slipped in the past.
• Commercial viability: extraction costs and metal prices remain uncertain.

Delhi’s Deepavali Night: PM2.5 Reaches 200 Times the WHO Limit as Monitoring Data Go Missing

Core TopicGS-III · Environment — Pollution, Conservation; Environmental GovernancePrelims + MainsThe Hindu

Firecrackers were burst well past the Supreme Court’s 10 p.m. deadline on 8 November, and PM2.5 at some Delhi stations rose to 150–200 times the WHO limit. At the same time, data were missing from several monitoring stations at the peak, which, experts say, makes recorded air quality look better than it was.

◈ From the Basics — Particulate Matter, Standards and the AQI

• PM2.5: particles of 2.5 micrometres or less, about 1/30th the width of a human hair. They penetrate deep into the lungs and bloodstream, causing respiratory, cardiovascular and other diseases.
• WHO Air Quality Guidelines (2021): PM2.5 of 15 µg/m³ (24-hour) and 5 µg/m³ (annual).
• India’s NAAQS (2009): PM2.5 of 60 µg/m³ (24-hour) and 40 µg/m³ (annual). These are notified by the CPCB under the Air (Prevention and Control of Pollution) Act, 1981.
• National AQI (2014): covers 8 pollutants and 6 categories, from Good (0–50) to Severe (401–500). The figure for the day is the CPCB’s 4 p.m. bulletin, a 24-hour average.
• Green crackers: developed by CSIR-NEERI, they cut emissions by about 30% using alternative chemistry and dust suppressants, but they still pollute.

Figure 1 — Peak PM2.5 on Deepavali Night vs Standards (µg/m³)

NSUT West (5 a.m.)3,008.4Patparganj (1 a.m.)2,597India NAAQS (24-hr)60WHO guideline (24-hr)15Peaks are hourly readings (DPCC); standards are 24-hour averages, shown only for scale.

The peak at NSUT West was about 200 times the WHO guideline and 50 times India’s own standard. Missing peak-hour data would understate exposure on such nights.

▤ The Numbers

• Patparganj: 2,597 µg/m³ at 1 a.m. (about 173× WHO). NSUT West Campus: 3,008.4 µg/m³ at 5 a.m. (about 200×).
• Delhi AQI: 376 on Deepavali day and 344 the next day, both “very poor”.
• Stubble fires in Punjab: 1,152 on Sunday (the season’s highest), 198 on Monday, and 4,657 for the season, the second lowest since 2020 (IARI bulletin).
• Stubble’s share of Delhi’s PM2.5 on Sunday was 5.1% (MoES data).

Why the Spike Faded Quickly

• According to SAFAR (System of Air Quality and Weather Forecasting And Research, under MoES), the wind shifted from north-westerly (carrying stubble smoke) to easterly/south-easterly on Sunday afternoon, and wind speed picked up. This dispersed pollutants by morning.
• Winter meteorology normally does the opposite. Low wind speeds, falling temperatures and a low mixing height trap pollutants over the Indo-Gangetic Plain, adding to emissions from vehicles, dust, industry and seasonal stubble burning.

Governance Issues

• Data integrity: gaps in CAAQMS (Continuous Ambient Air Quality Monitoring Stations) data at peak hours undermine public trust and GRAP decisions. Missing peaks lower the computed averages.
• Enforcement gap: the Supreme Court permitted only green crackers in fixed time windows on 7–8 November, yet traditional crackers were sold openly.
• Politicisation: political parties traded charges over the missing data and stubble burning, which diverts attention from airshed-level solutions.
• Institutions: the Commission for Air Quality Management (CAQM) (statutory under the CAQM Act, 2021) coordinates across NCR and adjoining States. The National Clean Air Programme (NCAP, 2019) funds city action plans.

Way Forward

• Mandatory public disclosure of station downtime, and independent audits of monitoring networks.
• Stricter control of cracker supply chains (manufacture, transport, sale) rather than end-use policing alone.
• Year-round action on vehicles, construction dust and industry. Episodic festival bans address only the peaks.
• Regional airshed governance across the Indo-Gangetic Plain, with stubble management through in-situ machinery, ex-situ use (biomass pellets, ethanol) and crop diversification.

Episodic pollution peaks in Delhi expose deeper weaknesses in air-quality governance, from enforcement to data integrity. Critically examine, and suggest an airshed-based approach for the Indo-Gangetic Plain. 15 marks · 250 words

How Liuyang Became the World’s Fireworks Factory, and What It Means for Sivakasi

ConciseGS-I · World History; Location of IndustriesGS-III · Industrial Safety & PollutionPrelims + MainsThe Indian Express

Most of the fireworks burst in India at Deepavali come from Sivakasi, Tamil Nadu. Globally, however, China makes about 90% of all fireworks, and one city dominates the trade: Liuyang in Hunan province.

◈ Static Background — Gunpowder and Fireworks

• Gunpowder (black powder) is a mixture of saltpetre (potassium nitrate, which supplies oxygen), charcoal and sulphur (the fuels). It was discovered by Chinese alchemists searching for an elixir of immortality.
• Early fireworks were powder packed into bamboo, and are linked to the Tang dynasty (618–907 CE). Gunpowder is one of China’s “Four Great Inventions”, with paper, printing and the compass.
• Cultural root: according to folklore, firecrackers were meant to scare away ‘Nian’, a mythical beast that attacked people and livestock at the turn of the year and feared loud noises. This is why they are central to the Lunar New Year.

Why Liuyang Leads

• Scale: Liuyang accounts for about 60% of China’s fireworks market and about 70% of its exports.
• From cottage industry to factories: for centuries, families mixed powder and filled shells by hand. Production revived strongly after the 1972 US presidential visit to China reopened trade and know-how.
• Factor advantages: cheap and abundant labour, lax regulation of hazardous work, low capital needs, and strong domestic demand during festivals.
• Rebranding: fireworks are now marketed as part of an “emotional economy” of year-round shows. Liuyang has hosted 142 major displays since 2023, drawing over 7 million visitors.
• Safety and pollution: a May 2026 factory explosion killed 26 people. The city has adopted AI-enabled cameras and centralised risk warnings. Bans have been imposed for air-quality reasons (e.g., Beijing, 2018) and sometimes reversed in the face of public opposition (Henan, 2017).

▤ India Parallel — Sivakasi

• Sivakasi (Virudhunagar district, Tamil Nadu) supplies the bulk of India’s fireworks. The cluster grew there because of its dry climate and low rainfall, which suit drying chemicals.
• Regulation: the Explosives Act, 1884 and Explosives Rules, 2008, administered by PESO (Petroleum and Explosives Safety Organisation, Nagpur). Fireworks imports are restricted under the foreign trade policy.
• Common challenges: recurring factory explosions, past use of child labour, the shift to green crackers, and court-imposed limits on cracker use.

India’s Century of Grandmasters: What the Numbers Say About a Chess Powerhouse

ImportantGS-I · Indian Culture (Origin of Chess); Sports & SocietyPrelims-orientedThe Hindu · Data Point

Anuj Shrivatri, 22, of Katni, Madhya Pradesh, became India’s 100th Grandmaster after winning the 7th ASEAN+ Individual Open Chess Championship in Ozamiz City, the Philippines, with 7/9 points. He is also Madhya Pradesh’s first GM.

◈ Static Background — Chess and Its Titles

• Origin in India: chess traces back to chaturanga (c. 6th century CE, Gupta era). The name refers to the four divisions of an army: infantry, cavalry, elephants and chariots. The game spread through Persia (as shatranj) to the Arab world and Europe.
• FIDE (Fédération Internationale des Échecs), the world governing body, was founded in 1924 in Paris and is now based in Lausanne. It awards titles such as Grandmaster (GM), the game’s highest lifetime title.
• GM norms: broadly, a player needs three GM norms (performance benchmarks in strong tournaments) and a rating of at least 2500. Some championships confer the title directly.
• Milestones: Viswanathan Anand became India’s first GM in 1988. India hosted the 44th Chess Olympiad (Chennai, 2022), won both Olympiad golds (Open and Women, Budapest 2024), and D. Gukesh became the youngest undisputed world champion in December 2024.

Reading the Numbers

• Geography: Tamil Nadu (38), Maharashtra (14), West Bengal (12), Delhi (8) and Andhra Pradesh (7). The concentration reflects coaching ecosystems and early role models, Chennai’s in particular.
• Growth: it took 14 years to produce the first five GMs. The count was 23 in 2010 and 67 in 2020, and 56 were added between 2016 and 2026. Annual additions vary, for example only 2 in 2020 (COVID-19) but 10 in 2026.
• Average age of new GMs was 19.9 in 2026. Because some years produce a single GM, annual averages fluctuate sharply and indicate a trend rather than a steady decline.
• Global standing: India is 4th by number of registered GMs (97), behind Russia (184), the US (115) and Germany (103). It is 2nd by the top-10 average rating (2,706), just behind the US (2,719) and ahead of China (2,663).
