It reverses a six-year policy of zero MDR on UPI. ◈ Static Background — From the Basics A payment system is the set of rules, institutions and technology that moves money from a payer to a payee. In India, every such system needs authorisation from the Reserve Bank of India (RBI) under the Payment and Settlement Systems (PSS) Act, 2007. PSS Act, 2007 — makes RBI the designated authority for payment systems; oversight is exercised through the Board for Regulation and Supervision of Payment and Settlement Systems (BPSS), a committee of the RBI Central Board. NPCI (National Payments Corporation of India) — set up in 2008 as an umbrella retail-payments organisation promoted by RBI and the Indian Banks’ Association; a not-for-profit (Section 8) company. It runs UPI, IMPS, RuPay, NACH, AePS and FASTag (NETC). UPI (Unified Payments Interface) — launched by NPCI in April 2016, built on the IMPS rails. It links multiple bank accounts to one app through a Virtual Payment Address (VPA) and settles 24×7 in real time. P2P vs P2M — Person-to-Person transfers move money between individuals; Person-to-Merchant payments are made to a business. P2PM is NPCI’s category for small merchants (such as street vendors) who accept payments on a personal-style QR. What is MDR? The Merchant Discount Rate is the fee a merchant (not the customer) pays on each digital payment it receives. It is shared among the acquiring bank, the issuing bank, the payment app / PSP and the network. Card MDRs have long existed; UPI’s MDR was set to zero. Lineage — How UPI Became Free, and Why That Is Now Changing Union Budget, July 2019 — announced that businesses with turnover above ₹50 crore must offer low-cost digital modes with no MDR on either customer or merchant. 1 January 2020 — zero MDR took effect for UPI and RuPay debit cards, given legal force through Section 10A of the PSS Act (inserted by the Finance (No. 2) Act, 2019) read with the income-tax provision on prescribed electronic modes. August 2022 — RBI released a Discussion Paper on Charges in Payment Systems, asking whether UPI should carry a tiered charge. The Government then said it was not considering any charge on UPI. April 2023 — NPCI allowed an interchange of up to 1.1% on merchant payments above ₹2,000 made from prepaid wallets (PPIs) over UPI. Bank-account-to-merchant UPI remained free. Incentive schemes — to compensate banks for zero MDR, the Union Cabinet approved budgetary incentives for RuPay debit and low-value BHIM-UPI P2M payments, including ₹2,600 crore for 2022-23 and ₹1,500 crore for 2024-25 (the latter for payments up to ₹2,000 to small merchants). September 2026 — the new framework, notified under the PSS Act, 2007 after deliberations of the UPI Steering Committee, introduces a limited MDR on higher-value merchant payments. ▤ Framework at a Glance Statutory basis: Payment and Settlement Systems Act, 2007; rates settled by the UPI Steering Committee. Nodal Ministry: Ministry of Finance (Department of Financial Services); operator — NPCI; regulator — RBI. Always free: all P2P transfers of any amount — no transaction fee, platform fee or other charge on individuals. No MDR: P2M payments up to ₹2,000; and all receipts of small merchants under P2PM receiving up to ₹1 lakh per month via UPI QR. General MDR: 0.4% on P2M payments above ₹2,000, capped at ₹300 per transaction (the cap binds from ₹75,000). Essential & thin-margin sectors: flat ₹5 per transaction above ₹2,000 — railways, telecom, insurance, fuel, agricultural inputs. Capital markets: 0.02%, capped at ₹300 — mutual funds, securities, stockbrokers and dealers. Customer protection: banks advised to stop merchants passing MDR to customers; UPI apps prohibited from platform fees or hidden charges; no monthly quotas on free use. Small-merchant fund: 5% of total MDR collections to a dedicated fund for UPI adoption among small merchants. Coverage estimate: about 96% of P2M transactions unaffected; P2P accounts for about 70% of UPI value (Government estimates). Figure 1 — Who Pays What: The New UPI Charging Tree UPI TransactionPerson-to-PersonPerson-to-MerchantFREE — any amountno fee on individualsUp to ₹2,000No MDRSmall merchant (P2PM)≤ ₹1 lakh/month: zeroAbove ₹2,000MDR appliesGeneral merchants0.4%cap ₹300 (≥ ₹75,000)Essential sectorsflat ₹5 / txnrail, telecom, fuel…Capital markets0.02%cap ₹300Green = free · Gold = MDR borne by merchant, not by customer The charge sits only on the right-most branch — higher-value payments to merchants that are not small P2PM vendors. Working the Numbers — What a Merchant Actually Pays Because the 0.4% rate is capped at ₹300, the effective rate falls for very large tickets. A ₹2,00,000 payment attracts ₹300, not ₹800 — an effective rate of 0.15%. The figures below are computed directly from the notified rates.

Why It Matters Viability of Digital Public Infrastructure (DPI): zero MDR left banks and apps with no direct revenue from UPI, making ecosystem costs — fraud control, uptime, rural acceptance — dependent on budgetary incentives. Fiscal angle: a merchant-side fee on larger payments shifts part of the cost from the Union Budget to the users best able to bear it. Inclusion protected by design: the free tiers cover individuals, micro-enterprises and street vendors — the groups whose adoption drove UPI’s growth. Sectoral calibration: a flat ₹5 for thin-margin sectors and 0.02% for capital markets show an attempt to avoid distorting essential services and retail investment. Parliamentary input: the Government states the framework is consistent with the Standing Committee on Finance’s 32nd Report, which stressed a viable revenue model. The Critical View Count vs value: 4% of P2M transactions by number may be a much larger share by value, because only high-ticket payments are charged. The revenue base is concentrated in fewer, bigger merchants. Pass-through risk: banks are only “advised” to stop merchants surcharging customers. Enforcement against hidden price loading will be difficult to monitor across millions of outlets. Transaction-splitting and category gaming: a ₹2,000 threshold invites splitting of bills, and the zero-MDR P2PM category may be used by merchants who are not genuinely small. Legal consistency: the zero-MDR mandate rests on Section 10A of the PSS Act; the instrument reconciling the new charge with that mandate needs clear public notification. Market concentration: MDR revenue shared with apps may reward the largest third-party apps. NPCI’s proposed 30% volume cap per app, first announced in November 2020, has seen its compliance deadline extended repeatedly. Behavioural shift: some high-value merchants may nudge buyers back to cash or to other instruments, working against the less-cash objective. ◈ Institutions & Terms — Prelims Hooks Interchange fee — the part of a payment fee paid by the acquiring bank to the issuing bank; MDR is the broader fee paid by the merchant. PSP (Payment Service Provider) bank — a bank that connects a Third-Party App Provider (TPAP) to UPI; apps cannot connect to NPCI directly. UPI Lite (2022) — on-device wallet for small-value payments without a bank-server call; UPI123Pay (2022) — UPI for feature phones. RuPay credit cards on UPI — permitted from 2022; credit lines on UPI followed in 2023. Payments Infrastructure Development Fund (PIDF) — RBI’s fund (from 2021) to deploy acceptance infrastructure in Tier-3 to Tier-6 centres; a useful comparison for the new 5% small-merchant fund. ✎ Mains Practice Question “Zero MDR helped UPI achieve mass adoption but left its operators without a sustainable revenue model.” Critically examine whether a calibrated merchant discount rate can balance the sustainability of digital public infrastructure with the goal of financial inclusion. 15 marks · 250 words 02 Varuna Elevated Corridor — An Elevated Highway Along a River in One of India’s Oldest Living Cities GS-III · Infrastructure — Roads, Urban Mobility, LogisticsGS-I · Urbanisation & HeritagePrelims + MainsPIB · Ministry of Road Transport & Highways · 15 Sep 2026 A 43.218-km, ₹10,998-crore elevated highway will run along the Varuna river to link NH-31 with the Varanasi Ring Road — testing how India adds road capacity to a dense heritage city without widening its historic lanes. ◈ Static Background — From the Basics The city’s name: Varanasi is traditionally derived from two tributaries of the Ganga — the Varuna on its northern side and the Assi on its southern side. It is also known as Kashi and Banaras. Setting: the city lies on the western (left) bank of the Ganga, where the river flows northward (Uttaravahini) — one reason for its ghats-facing-east orientation and religious significance. Constitutional basis of highways: highways declared by Parliament to be national highways are in Entry 23, Union List (Seventh Schedule); they are declared under the National Highways Act, 1956. NHAI: constituted under the National Highways Authority of India Act, 1988, operational from 1995; it is the implementing agency under MoRTH. PM Gati Shakti National Master Plan — launched in October 2021, a GIS-based platform integrating infrastructure planning across ministries; complemented by the National Logistics Policy (September 2022). Heritage law: the Ancient Monuments and Archaeological Sites and Remains (AMASR) Act, 1958, as amended in 2010, bars new construction within a 100-m prohibited area and regulates it within a further 200-m regulated area around centrally protected monuments. ▤ Project at a Glance Total cost: ₹10,998 crore; the release itemises ₹4,565.33 crore for civil construction and ₹934.91 crore for land acquisition — together ₹5,500.24 crore; the balance is not broken down. Length & design: 43.218 km, predominantly elevated 6/4-lane, with flyovers, loops, ramps and service roads; design speed 80–100 km/h. Approving authority: Union Cabinet, July 2026. Implementing agency: NHAI under the Ministry of Road Transport & Highways. Alignment: along the Varuna river, linking NH-31 with the Varanasi Ring Road; part of the Varanasi Decongestion Plan. Signature structures: an iconic cable-stayed bridge and an extradosed foot-over-bridge-cum-major bridge. Connectivity nodes: Lal Bahadur Shastri International Airport, Varanasi Cantonment, Varanasi City and Kashi stations, Deen Dayal Upadhyaya Junction, Ramnagar port, the Chandauli Socio-Economic Zone and six logistics nodes. Stated outcomes: NH-31 to Kashi station cut from about 40 to 20 minutes; Varanasi Junction to the airport from nearly an hour to about 20 minutes (government projections). ₹10,998 cr Sanctioned cost 43.218 km Corridor length 80–100 Design speed (km/h) 6/4-lane Mostly elevated Figure 3 — Projected Travel Time (minutes) NH-31 → KashiRailway Station~40 min~20 minVaranasi Junction →LBS Int’l Airport~60 min~20 minCurrent (approx.)Projected by the Government Both routes are projected to fall to about 20 minutes — outcomes to be tested once the corridor opens. From the Basics — Three Ways to Build a Bridge The corridor combines two bridge forms. A cable-stayed bridge hangs its deck directly from tall pylons through straight cables. An extradosed bridge is a hybrid: short pylons carry cables at a shallow angle that act like external prestressing for a stiff girder deck. Figure 4 — Girder vs Extradosed vs Cable-Stayed (schematic) Girder bridgeDeep beams carry the load;spans are relatively shortExtradosed bridgeShort pylons, shallow cablesstiffen a girder deckCable-stayed bridgeTall pylons, cables hold thedeck directly — longest spans Extradosed designs sit between girder and cable-stayed bridges — useful where pylon height must be kept low, such as near heritage skylines or flight paths. Lineage & Linkages Bharatmala Pariyojana (Phase-I, approved October 2017) — the umbrella highway programme under which many ring roads, bypasses and economic corridors were planned. Varanasi Ring Road — built to divert through traffic around the city; the corridor now links it with NH-31 through the city along the Varuna. Ramnagar multimodal terminal on National Waterway-1 (Ganga) — inaugurated in November 2018 under the World Bank-assisted Jal Marg Vikas Project; road access decides whether such river terminals attract cargo. Deen Dayal Upadhyaya Junction (formerly Mughalsarai, renamed 2018) in Chandauli — a major rail hub on the Eastern Dedicated Freight Corridor alignment. Kashi Vishwanath Corridor (inaugurated December 2021) — has raised pilgrim footfall, sharpening the city’s peak-season congestion. The Critical View River and floodplain: piers in or beside the Varuna channel can affect flood flow and sediment. Floodplain regulation under the River Ganga (Rejuvenation, Protection and Management) Authorities Order, 2016 and environmental scrutiny will matter, as the Varuna is already a polluted tributary. Induced demand: transport research repeatedly finds that new urban road capacity attracts more traffic; without public transport and parking policy, time savings can erode. Heritage skyline: elevated structures near ghats or protected sites need AMASR Act clearances and heritage impact assessment, and change the visual character of a historic city. Cost transparency: only about half of the ₹10,998-crore cost is itemised in the release; the implementation mode (EPC, HAM or BOT) is also not stated. Rehabilitation: land acquisition along a dense river corridor must follow the RFCTLARR Act, 2013, including Social Impact Assessment for affected residents and informal settlements. ✎ Mains Practice Question Infrastructure in India’s historic cities must reconcile mobility, heritage conservation and river ecology. Discuss the challenges involved, with reference to elevated road corridors in heritage cities, and suggest safeguards. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III 03 SEMICON India 2026 and the Semiconductor Mission — How a Chip Works, and Where India Stands in the Value Chain GS-III · S&T — Electronics, Indigenisation; Economy — Industrial PolicyGS-II · IR — Supply-Chain AlliancesPrelims + MainsPIB Backgrounder · Ministry of Electronics & IT · 15 Sep 2026 SEMICON India 2026 opens at Yashobhoomi, Dwarka (New Delhi) on 17 September under the theme “Silicon to Systems: Building the Ecosystem” — two months after the Cabinet approved Semicon 2.0 with a ₹1,27,500-crore outlay. ◈ Static Background — Part A: What Is a Semiconductor? Materials are classed by how easily electrons move through them. Conductors (copper, aluminium) carry current freely; insulators (glass, silicon dioxide) almost block it. Semiconductors — chiefly silicon (Si) — lie in between, and their conductivity can be precisely controlled. Band theory: electrons in a solid occupy energy ranges called bands. The filled valence band and the higher conduction band are separated by a band gap (Eg). An electron must gain at least Eg of energy to conduct. Typical band gaps: germanium ≈ 0.66 eV, silicon ≈ 1.12 eV, gallium arsenide ≈ 1.42 eV, silicon carbide ≈ 3.2 eV, gallium nitride ≈ 3.4 eV; insulators such as SiO2 ≈ 9 eV. Temperature behaviour: a semiconductor’s resistance falls as temperature rises (more electrons cross the gap) — the reverse of metals, whose resistance rises with heat. Wide-bandgap (compound) semiconductors like SiC and GaN tolerate high voltage, heat and frequency — used in EV power electronics, fast chargers, 5G and radar. Figure 5 — Conductor, Semiconductor and Insulator: The Band-Gap Picture EnergyConductor (metal)Conduction bandValence bandBands overlap: no gapSemiconductor (Si)Conduction bandValence bandEg ≈ 1.1 eVSmall gap: controllableInsulator (SiO₂)Conduction bandValence bandEg ≈ 9 eVLarge gap: blocks current The size of the band gap decides whether a material conducts, blocks, or — like silicon — can be switched between the two. ◈ Static Background — Part B: Doping, Junctions and the Transistor Intrinsic vs extrinsic: pure silicon is intrinsic and conducts poorly. Adding tiny, controlled impurities — doping — makes it extrinsic. n-type: doped with pentavalent atoms (phosphorus, arsenic, antimony) — extra electrons are the majority carriers; the dopants are called donors. p-type: doped with trivalent atoms (boron, aluminium, gallium, indium) — holes (missing electrons) are the majority carriers; the dopants are acceptors. p–n junction: joining p- and n-regions creates a depletion region that lets current flow easily in one direction only — the basis of the diode, LED and solar cell. Transistor: a switch or amplifier with no moving parts — invented at Bell Labs in 1947 (Bardeen, Brattain, Shockley; Nobel Prize 1956). The integrated circuit followed in 1958–59 (Jack Kilby, Robert Noyce). MOSFET (Metal–Oxide–Semiconductor Field-Effect Transistor) — demonstrated at Bell Labs in 1959 (Mohamed Atalla, Dawon Kahng); today the most manufactured device in history and the building block of every digital chip. How a MOSFET Switches — Reading the Band Diagram At the heart of a MOSFET is a MOS capacitor: a metal gate, a thin insulator (oxide), and a doped silicon body. Applying a gate voltage (V) does not push current through the insulator — it bends the energy bands in the silicon beneath it. Figure 6 — MOS Capacitor: Depletion (top) and Inversion (bottom) Left: conduction (green) and valence (red) edges bend near the insulator as gate voltage V rises. Right: charge on each side of the insulator. Image supplied for this analysis — a standard MOS-capacitor band diagram; reproduced for educational use. Top panel — depletion: a modest positive gate voltage on a p-type body repels mobile holes from the surface. What remains is a layer of fixed, negatively charged acceptor ions (−QA), balanced by charge Q = QA on the gate. The bands bend only slightly. Bottom panel — inversion: at a higher voltage the bands bend so far that the conduction-band edge approaches the electron energy level at the surface. A thin sheet of mobile electrons (Qn) forms right at the interface; the gate charge becomes Q = Qn + QA. Why this matters: that electron sheet is the inversion layer — a conducting channel. Add n+ source and drain regions on either side and the MOS capacitor becomes a MOSFET. The switch: below the threshold voltage (VT) there is no channel — OFF (0); above VT the channel conducts — ON (1). Billions of such switches make up a processor. Why the oxide must be thin: a thinner insulator gives the gate stronger control, but too thin lets electrons tunnel through. Industry therefore moved from SiO2 to high-k dielectrics (hafnium-based) from the 45-nm era onward. ◈ Static Background — Part C: Nodes, Moore’s Law and Lithography Moore’s Law (1965) — Gordon Moore’s observation that transistor counts on a chip double roughly every two years (revised in 1975); it is an industry trend, not a physical law. Process “node” (e.g. 28 nm, 3 nm): once the physical gate length; today largely a generation label. Smaller nodes pack more transistors, use less power and cost far more to build. Transistor architecture: planar → FinFET (mass production from 22 nm, 2011) → Gate-All-Around (GAA) at 3 nm and 2 nm, where the gate wraps the channel on all sides. Photolithography prints circuit patterns with light. Advanced nodes need Extreme Ultraviolet (EUV) light at 13.5 nm; mature nodes use Deep UV (193 nm). The Netherlands’ ASML is the sole supplier of EUV scanners. Mature vs leading-edge: 28 nm and above (mature nodes) still serve automobiles, power management, defence and IoT — the segment most of India’s first projects target.

Lineage — India’s Long Road to a Fab Semi-Conductor Complex Ltd (SCL), Mohali — a public-sector fab incorporated in 1976, producing from 1984; a fire in 1989 set back India’s early lead. It survives as a mature-node facility used for strategic and academic chips. Special Incentive Package Scheme (SIPS), 2007 — offered capital subsidies for fabs; attracted proposals but no fab was built. 2013–14 — two fab consortia received in-principle approval (Jaiprakash Associates–IBM–TowerJazz and HSMC–STMicroelectronics–Silterra); both lapsed for want of finance and demand certainty. National Policy on Electronics: 2012 → 2019 — NPE 2019 set a target of US$400 billion of electronics manufacturing by 2025. 2020 — PLI Scheme for Large-Scale Electronics Manufacturing, SPECS and EMC 2.0 — pulled global mobile assembly into India. December 2021 — Semicon India Programme (₹76,000 crore) and the India Semiconductor Mission (ISM), an independent business division within Digital India Corporation under MeitY. July 2026 — Semicon 2.0 (₹1,27,500 crore) approved, built on six pillars. ▤ Mission at a Glance Semicon 1.0 outlay: ₹76,000 crore (approved 2021) — fabs, display fabs, compound semiconductors, ATMP/OSAT, and the Design Linked Incentive (DLI) scheme. Support model (1.0): fiscal support of up to 50% of project cost on a pari-passu basis for fabs and packaging units, often topped up by State incentives. Semicon 2.0 outlay: ₹1,27,500 crore, approved by the Union Cabinet in July 2026. Six pillars of 2.0: chip design, equipment & materials, fabrication, advanced packaging, R&D, talent. Nodal body: India Semiconductor Mission, Ministry of Electronics & IT. Projects: 12 approved across six States, investment commitments above ₹1.64 lakh crore; spanning silicon and compound fabs, display fabrication and advanced packaging. Status: three facilities in commercial production (as stated by the Government). Talent target: 85,000 skilled semiconductor engineers within the decade (government target). The Electronics Base — Assembly as the Proof of Concept The Government presents the growth of electronics and mobile manufacturing since 2014-15 as the foundation for chipmaking. The figures below are as stated in the backgrounder; they measure gross output, not domestic value addition. Figure 8 — Electronics Output and Exports (₹ lakh crore), 2014-15 vs 2025-26 2014-152025-26Electronicsproduction1.913.11 (≈7×)Electronicsexports0.384.24 (≈11×)Mobile phoneproduction0.186.27 (≈33×)Mobile phoneexports0.0152.59 (≈165×)Values as stated in the PIB backgrounder · gross output, not value added The steepest multiples are in mobile exports, which started from a near-zero base — a reminder to read growth multiples against base values. Smartphones were, per the Government, India’s largest single exported commodity in FY 2025-26, ahead of petroleum products and gems & jewellery. India is the second-largest mobile phone manufacturer by volume; the Government states that 99.2% of phones used in India are made domestically and that the sector supports about 2.5 million jobs. Building the Talent Pipeline Chips to Startup (C2S) Programme — EDA tools deployed in 320 academic institutions; over 68,000 students trained. Design Linked Incentive (DLI) Scheme — 24 chip-design projects approved for support; 105 start-ups and MSMEs given EDA tool access. Tape-outs: by April 2026, 211 chips taped out by 75 institutions; seven fabricated, at nodes down to 12 nm. A tape-out is the final design sent for fabrication. ChipIN Centre at C-DAC — a centralised national facility for design tools, fabrication access and training; used by over 1 lakh engineers from 500+ organisations, with 300+ designs sent for fabrication at SCL Mohali and foreign foundries. The Geopolitics of Chips — Pax Silica and the Global Subsidy Race The COVID-19 chip shortage idled car plants worldwide and exposed how concentrated production is. Taiwan’s TSMC earns roughly two-thirds of global foundry revenue, and ASML alone makes EUV scanners. Governments responded with industrial policy on a scale not seen in decades. Pax Silica — a US-led supply-chain coalition launched in December 2025 to secure the full “silicon stack”, from critical minerals and fabrication to AI systems. India joined during the India AI Impact Summit, February 2026. United States: CHIPS and Science Act, 2022 — about US$52.7 billion for domestic chip manufacturing, research and workforce. European Union: European Chips Act, 2023 — aims to double the EU’s global production share to 20% by 2030. Japan: subsidies for TSMC’s Kumamoto fab and the Rapidus 2-nm project in Hokkaido. India–US track: the iCET (2022–23), relaunched as TRUST in 2025, covers semiconductors and critical minerals; India is also a member of the Wassenaar Arrangement (since 2017), relevant to dual-use technology controls. ▤ SEMICON India — Event Facts Organisers: SEMI (global industry association for the electronics supply chain) with the India Semiconductor Mission. Past editions: 2022 Bengaluru, 2023 Gandhinagar, 2024 Greater Noida, 2025 New Delhi. 2026 edition: Yashobhoomi (IICC), Dwarka; three days from 17 September; theme “Silicon to Systems: Building the Ecosystem”. Scale: 600+ exhibitors, 300 international companies, 15,000 sq m, 150+ speakers, six country and 12 State pavilions, a start-up showcase, student hackathon, workforce pavilion and women’s forum. The Critical View Fab economics: fabs are among the most capital-intensive plants in industry and become outdated quickly. With up to half the cost met by the Centre and more by States, the subsidy per job is very high and returns depend on sustained utilisation. Mature-node focus: India’s first fabs target 28 nm and above — strategically useful, but a crowded market where China is rapidly adding capacity, raising price-competition risks. Import dependence persists: equipment, speciality gases, chemicals and wafers are largely imported; the equipment & materials pillar of Semicon 2.0 addresses the gap that earlier schemes left. Resource intensity: fabs need uninterrupted power and large volumes of ultra-pure water — a concern in water-stressed States such as Gujarat, where several units are located. Assembly ≠ value addition: the electronics boom rests largely on final assembly of imported components; the NPE 2019 target of US$400 billion by 2025 was not met. Talent quality: training counts show reach, but fab-floor process engineers and equipment technicians — skills built only through years of production — remain scarce. Alignment risk: membership of US-led coalitions can bring technology access but also export-control obligations that may constrain trade choices; India’s traditional strategic autonomy must be balanced. ◈ Terms to Know — Prelims Hooks Fabless — designs chips without owning a fab; Foundry — manufactures chips designed by others; IDM (Integrated Device Manufacturer) — does both. OSAT — Outsourced Semiconductor Assembly and Test; ATMP — Assembly, Testing, Marking and Packaging. EDA — Electronic Design Automation software used to design and verify chips. Wafer — thin disc of ultra-pure silicon (today up to 300 mm) on which chips are made; die — one chip cut from it. Advanced packaging — stacking or tightly linking multiple dies (chiplets, 2.5D/3D) to raise performance without shrinking the node. SoC — System-on-Chip, integrating processor, memory controllers and other functions on one die. ✎ Mains Practice Question India has moved from electronics assembly towards semiconductor manufacturing, yet a self-reliant chip ecosystem requires far more than fabrication plants.

Core TopicEditorialGS-II · IR — Groupings (BRICS), Global GovernanceGS-III · S&T — AI, Cyber SecurityPrelims + MainsThe Hindu · Editorial After the 18th BRICS Summit in New Delhi, the editorial argues that open-source and collaborative AI among middle powers can shield the Global South from a technology race framed as U.S.–China rivalry. ◈ Static Background — From the Basics BRICS origins: the acronym “BRIC” was coined by a Goldman Sachs economist in 2001; foreign ministers first met in 2006, the first leaders’ summit was held at Yekaterinburg (Russia) in 2009, and South Africa joined in 2010. Expansion: Egypt, Ethiopia, Iran and the UAE joined from January 2024, and Indonesia in January 2025; a separate partner-country category was created at the Kazan Summit (2024). Institutions: the New Development Bank (NDB), agreed at Fortaleza (2014) and headquartered in Shanghai, and the Contingent Reserve Arrangement (CRA) of US$100 billion. BRICS has no charter or secretariat; it works by consensus. What is AI “alignment”? Ensuring an AI system pursues the goals its designers intend. Misalignment is when a system reaches a goal through unintended or harmful means. Open-source vs proprietary AI: proprietary (closed) models are accessed only through a company’s service; open-weight models release trained parameters for anyone to run and adapt. Fully open-source AI also releases code and, ideally, training data. Frontier AI: the most capable general-purpose models at any time — those most likely to create both large benefits and novel risks such as advanced cyber-offence. Issue in Brief — What the Editorial Argues A crossroads: the editorial contends that the U.S. government has disregarded frontier developers’ calls for a global slowdown over hacking and misalignment risks, while treating data-centre investment as key to competing with China. Contrasting summit positions: India’s Prime Minister warned against the “weaponisation” of technology and minerals, while China’s President promoted a “BRICS AI open source community” to counter any one country’s dominance. India’s middle path: India joined no protest against U.S.-led models but called for insulating AI from national rivalries — reflecting, the editorial says, both a young domestic AI ecosystem and the value of participating in deployment. Access as security: the editorial holds that timely and comprehensive access to AI is central to national security, and that trade disputes should not choke its spread. The prescription: BRICS should become a forum for making defensive AI capabilities broadly and cheaply available, since AI’s risks should not follow a “haves and have-nots” hierarchy. ▤ Data & Key Facts 18th BRICS Summit, chaired by India; the 140-paragraph New Delhi Declaration was adopted on 12 September 2026. China takes the chair for 2027. AI in the Declaration: members committed to implement the BRICS Leaders’ Statement on Global Governance of AI (adopted at the Rio de Janeiro Summit, 2025) and called for wider access to AI resources. Other tech initiatives: a proposed BRICS Startup Innovation Fund and a Risk Lab proposed for GIFT City; cooperation on DPI, cyber security, submarine cables and quantum. India AI Impact Summit (Bharat Mandapam, February 2026) — its New Delhi Declaration on AI Impact was endorsed by 88 countries and international organisations, around three “Sutras”: People, Planet, Progress. IndiaAI Mission — approved in March 2024 with an outlay of about ₹10,372 crore, covering subsidised GPU compute, foundation models, datasets (AIKosh) and skilling. Summit lineage: Bletchley Park (UK, 2023) → Seoul (2024) → Paris AI Action Summit (February 2025, co-chaired by India) → New Delhi (2026). Context the Editorial Refers To — The Fable and Mythos Suspension The editorial cites a “global pull out” of Anthropic’s Fable and Mythos models. On record, Anthropic suspended access on 12 June 2026 to comply with U.S. Department of Commerce export controls. The controls were lifted on 30 June, and access was restored on 1 July 2026. Why it matters for the argument: the episode showed how national export-control decisions can interrupt access to AI services for users in other countries, even briefly. Earlier precedent: the U.S. AI Diffusion Rule (January 2025) had placed India in a middle “Tier 2” for advanced AI-chip exports; it was rescinded in May 2025. Figure 1 — Three Approaches to AI in a Contested World (as framed in the editorial) Frontier-race approachOpen-source bloc approachIndia’s middle path• Capital-heavy data centres• Proprietary frontier models• Framed as U.S.–China race• Export controls as a toolRisk: access for othersdepends on one capital• Shared, open models• Pooled compute and data• Counter single-country lead• Collective cyber defenceRisk: capability lag, anda new dominant patron• No protest against U.S. models• Warns against weaponisingtechnology and minerals• Deployment-led gains• Plurilateral partnershipsRisk: squeezed betweenrival blocs India’s strategy aims to keep access to both proprietary and open ecosystems, avoiding exclusive dependence on either. Key Dimensions Strategic autonomy: India engages in U.S.-led technology partnerships (such as TRUST and Pax Silica) while co-authoring BRICS AI commitments — a form of multi-alignment applied to technology. Security: AI can automate the discovery of software vulnerabilities; states with weak cyber defences face the greatest exposure, making defensive AI a public good. Economic: for deployment-heavy economies, the gains come less from building frontier models than from applying AI to agriculture, health, language and public services. Governance: BRICS is not the only forum — the UN’s Independent International Scientific Panel on AI and Global Dialogue on AI Governance (created by the UN General Assembly, 2025) and GPAI offer overlapping tracks. Resources: the “weaponisation of minerals” reference links AI to the supply of critical minerals — gallium, germanium and rare earths — used in chips and hardware. Critical Analysis In favour of the editorial’s case: Open models reduce dependence: locally hosted open-weight models let countries keep sensitive data at home and avoid sudden loss of service. Collective bargaining: BRICS members together represent nearly half the world’s population, giving weight in setting norms on access and pricing. Shared defence is cheaper: pooling threat intelligence and defensive tools spreads costs that smaller states cannot bear alone. Against, or requiring caution: Intra-BRICS asymmetry: China’s AI capacity far exceeds other members’; an “open-source community” could deepen reliance on Chinese models and standards, a concern given India–China strategic differences. Openness cuts both ways: freely available powerful models can also spread offensive cyber capabilities to non-state actors — the very risk the editorial highlights. Consensus limits: BRICS lacks a secretariat, and its May 2026 foreign ministers’ meeting ended without a joint statement; converting declarations into programmes has been slow. Capability gap: the editorial itself concedes open models trail frontier systems; relying on them alone may leave critical defensive needs unmet. Way Forward Dual-track access: maintain partnerships with frontier providers while building sovereign compute and domestic open models under the IndiaAI Mission. Issue-based BRICS cooperation: focus on concrete, low-controversy areas — AI for cyber defence, multilingual datasets, shared evaluation and safety testing. Institutional depth: link BRICS AI work to NDB financing for compute and to DPI-style open standards that India has promoted. Safety institutions: strengthen India’s AI Safety Institute and CERT-In capacity so that access decisions rest on domestic risk assessment. ◈ Prelims Pointers BRICS chair rotation follows the order of the acronym — B-R-I-C-S; India chaired in 2012, 2016, 2021 and 2026. New Development Bank — first President was India’s K.V. Kamath; HQ Shanghai; regional centre in GIFT City, Gujarat. GPAI (Global Partnership on AI) — launched 2020; India is a founding member. Wassenaar Arrangement — multilateral export-control regime for dual-use goods; India joined in December 2017. “Sarvajan Hitaya, Sarvajan Sukhaya” — guiding principle of the India AI Impact Summit 2026. ✎ Mains Practice Question “Access to artificial intelligence is becoming a question of national security for developing countries.” In this context, examine whether groupings such as BRICS can provide a credible alternative to a geopolitically driven model of AI development, and discuss India’s strategic choices. 15 marks · 250 words Introduction: AI as dual-use technology; the 2026 BRICS Declaration and the export-control-driven access disruptions of 2025–26. Body: case for collaborative/open AI; limits — intra-BRICS asymmetry, consensus deficits, capability gap; India’s multi-alignment. Conclusion: dual-track access plus sovereign capacity and issue-based plurilateral cooperation. OpinionsSigned op-ed analysis 02 Youth Discontent and the Changing Face of Protest — Reading the Warning Signs Before Anger Coalesces Core TopicOpinionGS-II · Polity — Right to Protest, Accountability of InstitutionsGS-III · Internal Security — Role of Social Media, LWEGS-I · Society — YouthPrelims + MainsThe Hindu · Opinion Drawing on recruitment and entrance-exam protests across India in 2026, the author — a former security official — argues that unaddressed youth anger, handled with force rather than understanding, risks turning scattered agitations into a broader movement against authority. ◈ Static Background — From the Basics Right to protest: not named as such in the Constitution, but drawn from Article 19(1)(a) (speech and expression) and Article 19(1)(b) (to assemble peaceably and without arms). Limits: under Article 19(3), the State may impose reasonable restrictions in the interests of the sovereignty and integrity of India and public order. Key judgments: Ramlila Maidan Incident (2012) — use of force on sleeping protesters held excessive; Mazdoor Kisan Shakti Sangathan v. Union of India (2018) — no blanket ban on protests at Jantar Mantar; Amit Sahni (2020) — public spaces cannot be occupied indefinitely. Policing law: prohibitory orders now issue under Section 163 of the Bharatiya Nagarik Suraksha Sanhita (BNSS), 2023, replacing Section 144 CrPC. The UN Basic Principles on the Use of Force and Firearms (1990) require necessity and proportionality. Democratic peace theory: associated with Immanuel Kant’s “Perpetual Peace” (1795) — the idea that democracies rarely go to war with one another. Naxalism: began with the 1967 Naxalbari uprising in north Bengal; China’s official press hailed it as “Spring Thunder over India”. “A single spark can start a prairie fire” is Mao Zedong’s phrase (1930). Birsa Munda led the Ulgulan (“great tumult”) of 1899–1900 in the Chotanagpur region; his birth anniversary, 15 November, is observed as Janjatiya Gaurav Divas. Issue in Brief — What the Author Argues New forms of revolt: the author observes that Gen Z worldwide is turning to disruptive protest, driven chiefly by anger at an order seen as unequal to new problems. Neighbourhood lessons: youth-led upheavals in Bangladesh (2024) and Nepal (2025) ended long-established governments; in both, the author notes, protesters were first branded “foreign agents” or “anti-national”. Indian signals: a spontaneous, satire-driven youth movement’s Jantar Mantar sit-in over entrance-exam leaks, and student protests in Jharkhand, Chhattisgarh and Bihar, are presented as early warnings. Force is self-defeating: the author criticises the use against students of force meant for violent mobs, warning of a backlash against all authority. Misreading the anger: in Jharkhand, the author says, scrapping the examinations addressed the symptom but not the grievance, and comparisons with Birsa Munda’s uprising could inflame matters. Institutional trust: the author argues the youth perceive institutional safeguards weakening and power centralising, and urges all political actors to restore faith in the system. ▤ Data & Key Facts Jantar Mantar protests: held between 6 June and 25 July 2026, over alleged failures in national examinations, joined by several student organisations. Jharkhand: in August 2026, after a 16-day hunger strike by student leaders, the State Government cancelled the JSSC-CGL exam and all tests run by an outsourced agency since 2014; a section of protesters continued demanding a CBI probe. Public Examinations (Prevention of Unfair Means) Act, 2024 — penalises paper leaks with imprisonment of 3–5 years, rising to 5–10 years and a fine of at least ₹1 crore for organised crime. NTA reform: a high-level expert committee chaired by former ISRO chief K. Radhakrishnan recommended reforms to the National Testing Agency in 2024. Demography: youth aged 15–29 formed roughly 27% of India’s population (MoSPI, Youth in India 2022); the PLFS 2023-24 put youth unemployment at about 10%, well above the overall rate. Neighbourhood: Bangladesh — quota-reform protests ended the government in August 2024; Nepal — Gen Z protests, sparked by a social-media ban, led to the Prime Minister’s resignation in September 2025.

Key Dimensions Governance: repeated paper leaks and delayed recruitment damage the credibility of examination bodies, which for many young people are the main route to social mobility. Economic: high educated-youth unemployment concentrates aspirations on a limited number of government jobs, so each exam failure affects lakhs of candidates. Technological: social media lowers the cost of mobilisation; satire and memes give movements reach without formal organisation or leadership. Security: the author links unaddressed grievance to the historical growth of Left-Wing Extremism, which once drew in students and intellectuals, not only tribal and rural communities. Federal: recruitment bodies such as State Public Service and Staff Selection Commissions fall under State control, so responses vary widely across States. Ethical: labelling dissenters as “anti-national” or extremist can undermine democratic legitimacy and discourage peaceful expression. Critical Analysis In favour of the author’s concerns: Evidence of recurrence: examination controversies have recurred across national and State bodies, suggesting a systemic rather than isolated problem. Regional precedent: the pace at which youth protests in Bangladesh and Nepal escalated shows how quickly grievances can become regime-level crises. Legal backing: the Supreme Court has repeatedly held that peaceful protest is a constitutionally protected right, and that police force must be proportionate. Against, or requiring caution: Contextual differences: India’s federal structure, regular elections and independent courts provide outlets that were weaker in some neighbouring cases — the author himself notes the middle ground of Indian politics remains intact. Analogy risk: comparing exam protests with the Naxalite movement may overstate the threat and could itself be used to justify securitised responses. Scrapping exams: cancelling a compromised test can be a legitimate step to restore integrity, even if it imposes costs on honest candidates. Public order duties: authorities must also protect non-participants’ rights and prevent protests from turning violent; the balance is case-specific. Way Forward Exam integrity: implement the Public Examinations Act, 2024 and the NTA reform recommendations — secure digital question-paper delivery, vetted test centres, and fewer outsourced intermediaries. Predictable recruitment: publish and adhere to annual recruitment calendars, with time-bound results and grievance redress. Policing standards: train police in crowd management that distinguishes peaceful students from violent groups; ensure accountability for excessive force. Structured dialogue: create youth consultation forums within ministries and State commissions so grievances are heard before they reach the street. Employment: widen opportunities beyond government jobs through skilling, apprenticeships and private-sector job creation to ease pressure on a few exams. ◈ Prelims Pointers Article 19(1)(b) — right to assemble peaceably and without arms; restrictions under Article 19(3). Section 163, BNSS 2023 — power to issue orders in urgent cases of nuisance or apprehended danger (formerly Section 144 CrPC). National Testing Agency — set up in 2017 as a society under the Societies Registration Act, 1860; conducts NEET-UG, JEE Main, CUET and UGC-NET. Naxalbari — in Darjeeling district, West Bengal; uprising began in 1967. Ulgulan — Birsa Munda’s movement (1899–1900); the Chotanagpur Tenancy Act, 1908 followed partly in response. ✎ Mains Practice Question Youth-led protests driven by digital mobilisation are challenging conventional approaches to public order. Discuss the causes of rising youth discontent in India and suggest how the State can balance the right to protest with the maintenance of public order. 15 marks · 250 words Introduction: recent exam-related youth protests in India and youth-led upheavals in the neighbourhood. Body: causes — exam integrity, unemployment, trust deficit, digital mobilisation; constitutional framework (Art. 19, key judgments); risks of force and stigmatising labels. Conclusion: institutional reform, proportionate policing and structured dialogue as the path to legitimacy.

Together they form the “triple burden”. NFHS-5 (2019–21): among children under five, 35.5% stunted, 19.3% wasted, 32.1% underweight; 67.1% of children aged 6–59 months and 57% of women aged 15–49 were anaemic. ICDS — launched on 2 October 1975; its Anganwadi Centres deliver six services: supplementary nutrition, pre-school education, immunisation, health check-ups, referral services and nutrition–health education. POSHAN Abhiyaan — launched on 8 March 2018 at Jhunjhunu, Rajasthan, as a convergence mission; Poshan Maah (September) and Poshan Pakhwada (March–April) are its annual Jan Andolan campaigns. Mission Saksham Anganwadi & Poshan 2.0 — announced in Union Budget 2021-22; merges POSHAN Abhiyaan, Anganwadi Services (SNP) and the Scheme for Adolescent Girls. Legal anchor: the National Food Security Act, 2013 entitles pregnant and lactating women and children to meals through Anganwadis (Sections 4–5) and a maternity benefit of at least ₹6,000 (Section 4). PMMVY — the Pradhan Mantri Matru Vandana Yojana, a DBT maternity benefit of ₹5,000 for the first child; under Mission Shakti it also gives ₹6,000 for a second child if a girl. ▤ Poshan Maah 2026 at a Glance Theme: “Hamari Anganwadi, Hamari Jimmedari”; launch venue — Rudraksh International Cooperation and Convention Centre, Varanasi. Five priorities: dietary diversity & protein; fresh Hot Cooked Meals with weekly menu rotation and FSSAI quality testing; community ownership through Anganwadi Management Committees (AMCs) and SNP Menu Boards; nutrition + early stimulation for ECCE; and PMMVY’s 10 years. AMCs: guidelines issued on 23 June 2026; chaired by the Anganwadi Supervisor, for participatory oversight and social audit of meals. Early childhood: a revised Home Visit Scheduler with 34 developmental milestones for children aged 0–3; Navchetna (0–3) and Aadharshila (3–6) curricula; referral of developmental delays to RBSK teams. Network (31 July 2026): about 13.99 lakh Anganwadi Centres, 13.30 lakh Anganwadi workers, 8.94 crore beneficiaries. Previous edition: the 8th Poshan Maah (2025) recorded 14.33 crore activities in convergence with 20+ Ministries; the 8th Poshan Pakhwada (9–23 April 2026) focused on brain development in the first six years. Poshan Tracker — launched 1 March 2021 for near real-time monitoring of attendance, growth and service delivery. Figure 1 — Who Anganwadi Services Reach: 8.94 Crore Eligible Beneficiaries 8.94crore40.9% Children, 6 months–3 years40.0% Children, 3–6 years7.2% Pregnant women5.1% Children, 0–6 months5.1% Lactating mothers1.8% Adolescent girlsRecreated from Ministry of Women & Child Development data (PIB) Children aged 6 months to 6 years make up about 81% of beneficiaries; pregnant and lactating women together about 12%. Why It Matters The first 1,000 days — from conception to age two — shape lifelong cognitive and physical development; undernutrition in this window is largely irreversible. Protein gap: Indian diets are cereal-heavy; emphasising pulses, eggs, milk, nuts and millets targets poor dietary diversity, a key driver of stunting. From delivery to accountability: AMCs and public menu boards shift monitoring from top-down dashboards to community oversight — an application of social audit. Nutrition–learning link: tying meals to ECCE aligns the scheme with NEP 2020, which treats early childhood as the foundation of learning. The Critical View Outcomes lag outputs: campaign metrics (crores of activities) do not by themselves show falls in stunting and anaemia, which remain high. Overburdened frontline: Anganwadi workers are paid honoraria, not wages, yet handle nutrition, ECCE, surveys and digital entries — a long-standing demand for regularisation and better pay. Digital exclusion risks: mandatory app-based and biometric authentication for take-home rations can exclude beneficiaries with poor connectivity or mismatched records. Quality of food: take-home ration quality, supply chains and cost norms vary widely across States; testing drives need follow-up enforcement. PMMVY coverage: the benefit covers limited births and requires documentation, leaving informal-sector women and later births under-served. ✎ Mains Practice Question Despite an extensive Anganwadi network, malnutrition among children and women in India remains persistently high. Examine the role of community participation and early childhood care in improving nutrition outcomes under Mission Poshan 2.0. 15 marks · 250 words International Relations & Global CommonsGeneral Studies Paper II 02 U.S. Publicly Acknowledges On-Orbit “Space Control Weapons” — Exposing the Gaps in the Law Governing Space Militarisation GS-II · IR — International Treaties, Global CommonsGS-III · S&T — Space; Security — Emerging ThreatsPrelims + MainsThe Indian Express The United States has become the first country to publicly state that it has active weapons deployed in space, drawing objections from China and Russia and reopening the question of whether existing law can restrain an arms race in outer space. ◈ Static Background — From the Basics Militarisation vs weaponisation: militarisation is military use of space (reconnaissance, navigation, communication satellites) — long routine. Weaponisation is placing or using weapons that attack objects in, from or through space. Types of counter-space capability: Direct-ascent ASAT (missile from Earth); co-orbital (a satellite that manoeuvres to attack another); space-to-Earth strike; and non-kinetic means — jamming, spoofing, lasers, cyber attacks. ASAT tests: U.S. (1985; 2008 intercept), China (2007, Fengyun-1C), India (Mission Shakti, 27 March 2019, a satellite in low-Earth orbit at about 300 km), Russia (November 2021). All targeted their own satellites. Outer Space Treaty (OST), 1967 — the “Magna Carta” of space law. Article II bars national appropriation; Article IV bans placing nuclear weapons or other WMD in orbit and military bases on celestial bodies. India ratified it in 1982. Other UN treaties: Rescue Agreement (1968), Liability Convention (1972), Registration Convention (1975), Moon Agreement (1979) — the last not ratified by the major space powers. Institutions: UNOOSA (Vienna) and COPUOS for peaceful uses; the Conference on Disarmament (Geneva) for arms control, where PAROS (Prevention of an Arms Race in Outer Space) has been on the agenda for decades. What Happened The U.S. Air Force Secretary said the country now has “on-orbit space control weapons” to defend its forces against hostile action; their nature and deployment date were not disclosed. China’s foreign ministry urged the U.S. to stop “preparing for war in outer space”; the Kremlin called for the complete demilitarisation of space. The U.S. Space Force (created December 2019) accuses China and Russia of fielding counter-space capabilities aimed at U.S. space systems. Non-kinetic precedent: hackers disrupted ground systems of the Viasat satellite network just as the Russia–Ukraine war began in February 2022; GPS jamming has also been reported.

The Legal Gap OST’s narrow ban: it prohibits nuclear weapons and WMD in orbit but is silent on conventional weapons and on Earth-to-space weapons, which were not a practical prospect in the 1960s. PPWT (2008): a China–Russia draft Treaty on the Prevention of the Placement of Weapons in Outer Space would ban all weapons placed in space, but not ground-based ASATs; Western states rejected it as unverifiable. PAROS deadlock: the Conference on Disarmament works by consensus and has produced no treaty on space arms. Artemis Accords (2020) — a NASA–State Department non-binding framework for civil exploration with 70+ signatories, including India (June 2023); it requires peaceful purposes but does not bar weapons. Debris problem: kinetic ASAT tests create long-lived debris that threatens all satellites — Russia’s 2021 test, for instance, forced crew on the International Space Station to shelter. India’s Stakes Dependence on space assets: NavIC, communication, weather and earth-observation satellites underpin banking, disaster management and military command. Institutions: the Defence Space Agency and Defence Space Research Organisation (both 2019); the Indian Space Policy 2023 and IN-SPACe for private participation. Diplomatic line: India, a demonstrated ASAT power, states it opposes an arms race in space and supports PAROS, while keeping a credible deterrent. The Critical View Transparency cuts two ways: public acknowledgement may aid deterrence and signalling, but can also legitimise deployments and prompt matching moves. Verification problem: many satellites are dual-use — a servicing or debris-removal craft can also disable another satellite — making weapons hard to define or count. Norms vs treaties: with binding agreements stalled, behavioural norms (such as no destructive ASAT tests) may be more achievable than a comprehensive ban. ✎ Mains Practice Question The Outer Space Treaty, 1967 has proved inadequate to prevent the weaponisation of outer space. Critically examine the gaps in the existing legal regime and suggest how India can contribute to preventing an arms race in outer space. 15 marks · 250 words EconomyGeneral Studies Paper III 03 Merchandise Exports Jump 26% in August 2026 — Export Growth Outpaces Import Growth in Absolute Terms, Narrowing the Trade Deficit GS-III · Economy — External Sector, Balance of PaymentsPrelims + MainsThe Hindu · PIB (Ministry of Commerce & Industry) India’s merchandise exports rose 26.1% to US$43.8 billion in August 2026, while imports grew 14%. For the first time, according to the Commerce Secretary, export growth exceeded import growth even in absolute dollar terms. ◈ Static Background — From the Basics Trade balance = exports − imports. India runs a merchandise (goods) trade deficit — largely from crude oil, gold, electronics and coal — and a services trade surplus led by IT and business services. Current Account = goods trade + services trade + income + transfers (remittances). India’s large remittance inflows keep the current account deficit much smaller than the goods deficit. Exchange rate and trade: a depreciating rupee makes exports cheaper abroad and imports costlier at home. Under the Marshall–Lerner condition, depreciation improves the trade balance only if export and import demand are sufficiently price-elastic; the short-run worsening before improvement is the J-curve. Value vs volume: export value can rise because prices rise or because quantities rise; volume-led growth signals genuine gains in competitiveness. Data sources: merchandise trade data are compiled by the Directorate General of Commercial Intelligence and Statistics (DGCI&S), Kolkata; services data come from the RBI and are initially estimates. Policy frame: the Foreign Trade Policy 2023 (from 1 April 2023, no end date) targets US$2 trillion of goods and services exports by 2030. ▤ The Numbers — August 2026 Merchandise exports: $43.81 billion (Aug 2025: $34.74 bn) — up 26.1%, or $9.07 billion. Merchandise imports: $70.67 billion (Aug 2025: $61.96 bn) — up 14%, or $8.71 billion. Merchandise trade deficit: about $26.9 billion, marginally lower than about $27.2 billion a year earlier (computed from the above). Overall exports (goods + services): $82.7 billion, up 25.4%; overall imports: $92.1 billion, up 18.7%. Overall trade deficit: $9.4 billion, down from $11.6 billion in August 2025. April–August 2026-27: cumulative goods and services exports estimated at $399.27 billion, up 15.55% from $345.55 billion.

UAE: 37,359 (36,638) — +2.0%. China: 19,471 (14,252) — +36.6%. Netherlands: 17,501 (22,763) — −23.1%. Singapore: 11,864 (12,976) — −8.6%. Reading the Data Not just the rupee: the Commerce Secretary said growth was visible in both dollar and rupee terms and that export volumes rose strongly, countering the view that it was purely currency-driven. Destination shifts: the Netherlands is a major market for India’s refined petroleum, so its swings often reflect oil prices and refinery exports; the fall to the UAE contrasts with the long-term push under the India–UAE CEPA (in force May 2022). China: exports rose 52.3% in August, but India’s bilateral trade deficit with China remains the largest with any country, driven by imports of electronics, machinery and chemicals. Services cushion: implied services exports of about $39 billion against services imports of about $21 billion kept the overall deficit far below the goods deficit. The Critical View One month is not a trend: monthly trade data are volatile and affected by base effects, shipment timing and commodity prices. Depreciation’s cost: a weaker rupee raises the rupee cost of crude oil and imported inputs, feeding inflation and squeezing import-intensive exporters. Import content of exports: electronics and refined-product exports rely heavily on imported inputs, so gross export growth overstates domestic value addition. Concentration: reliance on a few markets exposes exports to tariff changes and demand shocks in those economies. ✎ Mains Practice Question A depreciating currency is often seen as a boost to exports, but its effect on the trade balance depends on the structure of trade. Examine this statement with reference to India’s recent export performance and the composition of its imports. 15 marks · 250 words 04 NPCI Introduces 0.4% Merchant Discount Rate on UPI Payments Above ₹2,000 From October 15 — Individuals and Small Vendors Exempt GS-III · Economy — Banking, Payment SystemsPrelims + MainsThe Hindu · Ministry of Finance The National Payments Corporation of India (NPCI) has introduced a Merchant Discount Rate on person-to-merchant UPI payments above ₹2,000, effective 15 October 2026 — ending the blanket zero-MDR regime that has applied to UPI since January 2020. ◈ Static Background — From the Basics MDR (Merchant Discount Rate): a fee the merchant — not the customer — pays on each digital payment it receives, shared among the acquiring bank, issuing bank, payment app and network. Zero MDR: from 1 January 2020, UPI and RuPay debit cards carried no MDR, under Section 10A of the Payment and Settlement Systems Act, 2007 (inserted in 2019). NPCI — set up in 2008 by RBI and the Indian Banks’ Association as a not-for-profit company; it launched UPI in April 2016. P2P vs P2M: person-to-person transfers between individuals versus person-to-merchant payments to businesses; P2PM is the category for small merchants using personal-style QR codes. Figure 5 — The New UPI Charges at a Glance Only mid-to-large merchants pay the 0.4% fee on payments above ₹2,000. Image courtesy The Hindu, 16 September 2026; reproduced with credit for educational use. ▤ The Framework General MDR: 0.4% on P2M payments above ₹2,000, capped at ₹300 for payments of ₹75,000 and above. Essential sectors: flat ₹5 per transaction above ₹2,000 — railways, telecom, insurance, fuel, agricultural inputs. Exempt: all P2P transfers; P2M payments up to ₹2,000 on UPI or RuPay debit cards; small merchants receiving up to ₹1 lakh a month via UPI QR under P2PM. Customer protection: banks advised to ensure merchants do not pass on the charge to customers. Share of P2P: 37% of UPI transactions by volume but 70% by value (Ministry of Finance). Effective date: 15 October 2026. Significance and Concerns Sustainability: gives banks and apps a revenue stream to fund fraud control, uptime and rural expansion, reducing reliance on budgetary incentives. Inclusion protected: exemptions shield individuals, street vendors and micro-businesses whose adoption drove UPI’s growth. Volume–value gap: since P2P is only 37% of volume, merchant payments are the majority of transactions — yet only high-ticket ones are charged, concentrating the fee on larger merchants. Enforcement: preventing hidden surcharges and bill-splitting below ₹2,000 across millions of outlets will be difficult to monitor. ✎ Mains Practice Question Discuss the rationale for introducing a merchant discount rate on high-value UPI payments. How can the design of such charges protect financial inclusion while ensuring the viability of India’s digital payments infrastructure? 10 marks · 150 words 05 NSO Releases First-Ever District-Level Estimates for the Unincorporated Non-Agricultural Sector From ASUSE 2025 GS-III · Economy — Informal Sector, Employment, Growth & DevelopmentGS-II · Governance — Evidence-Based PolicyPrelims + MainsPIB · Ministry of Statistics & Programme Implementation For the first time, the National Statistics Office has published district-level estimates from a nationwide survey — mapping establishments, workers, women’s participation and productivity of the unincorporated sector across 757 districts. ◈ Static Background — From the Basics Unincorporated enterprises are businesses not registered as companies — proprietorships, partnerships (other than LLPs), co-operatives, societies and trusts. They form the core of India’s informal economy. ASUSE (Annual Survey of Unincorporated Sector Enterprises) — covers manufacturing, trade and other services; it began in 2021-22, replacing periodic NSS rounds such as the 73rd Round (2015-16). NSO — formed in 2019 by merging the Central Statistics Office and the National Sample Survey Office under MoSPI. GVA (Gross Value Added) = value of output − value of intermediate consumption; GVA per worker is a simple measure of labour productivity. Sampling basics: a multi-stage stratified design — First Stage Units are census villages (panchayat wards in rural Kerala) and Urban Frame Survey blocks; Relative Standard Error (RSE) indicates how reliable an estimate is — higher RSE, lower reliability. Million-plus cities: 46 cities by Census 2011 population; MoSPI had earlier released a city-level profile of the sector for them. ▤ Key Findings Coverage: 757 of 770 districts in the sampling frame; Delhi excluded (all districts merged into one stratum), and Lakshadweep and Chandigarh covered by existing UT-level estimates. Concentration: the top 10 districts account for about one-tenth of establishments, workers and GVA; the top 50 for nearly one-third. Top-10 States: Gujarat, Telangana, Uttar Pradesh, West Bengal; the top 50 span 12 States. Scale: about one-third of districts have over 1 lakh establishments each; about 9% have under 10,000; only 16 districts exceed 5 lakh — eight in West Bengal. Productivity: all-India GVA per worker ₹1,56,539; 280 districts exceed it; about 331 districts lie between ₹1 lakh and ₹1.5 lakh. Women: top districts for female-led establishments are in Telangana, Manipur and Meghalaya; in every district of Mizoram, women own at least 50% of proprietary establishments. Women are one-third of the workforce in 237 districts and over half in 25. Why It Matters Granular planning: district data support targeting under the Aspirational Districts Programme (2018) and Aspirational Blocks Programme (2023), and district-level MSME cluster policies. Formalisation: registration status data help track reach of the Udyam Registration portal (2020) and the Udyam Assist Platform for informal micro enterprises. Gender policy: revealing high female entrepreneurship in the North-East and Telangana can guide credit and skilling schemes for women. Fiscal federalism: sub-State data can inform State Finance Commissions and district development plans. Caveats Sampling error: some estimates carry high RSEs; district comparisons must be read with caution. Boundary changes: the frame reflects districts at sample selection; newly created or renamed districts may not match. Productivity gap: GVA per worker of about ₹1.57 lakh a year signals low productivity typical of micro, own-account enterprises. ✎ Mains Practice Question Granular, sub-State data are essential for evidence-based policymaking. In light of the first district-level estimates of the unincorporated sector, discuss how such data can help address regional disparities and the low productivity of India’s informal enterprises. 10 marks · 150 words 06 China’s Industrial Tourism Boom — Factory Tours as a Tool for Branding, STEM Careers and National Pride GS-III · Economy — Industrial Policy, TourismGS-II · IR — Developments in ChinaMains-orientedThe Hindu · World Insight Bookings for factory tours in China rose over 36% this summer, with families making 68% of bookings, as a seven-department policy of May 2026 pushes manufacturing sites as tourist destinations. ◈ Background & Key Facts Industrial tourism — visits to working factories, industrial heritage sites and industrial museums, combining education, branding and leisure. Origins: began in the 1990s with breweries, dairies and petrochemical firms; in 2004, China designated 306 sites under a national industrial and agricultural tourism category. Scale: Beijing recorded 15 million industrial tourists and 1.7 billion yuan (about $248 million) in revenue in 2024. Policy link: the 15th Five-Year Plan (2026–2030) underlines expansion of AI, robotics and semiconductor education; tours are used to present STEM as a career path. Sectors: EVs, electronics, high-speed rail, aerospace, robotics; high-demand tours, such as those at Xiaomi, are allotted by lottery. Relevance for India Author’s suggestion: the author proposes selecting industrial hubs for public tours under a “Learn in India” banner, alongside Make in India (launched September 2014). Possible circuits: manufacturing States such as Tamil Nadu, Maharashtra and Gujarat; public-sector sites like ISRO centres, shipyards and steel plants could complement Swadesh Darshan 2.0. Constraints: safety and security of operating plants, protection of trade secrets, and the costs of visitor infrastructure. ✎ Mains Practice Question Can industrial tourism help India strengthen its manufacturing ecosystem and attract youth to STEM careers? Discuss with reference to international experience. 10 marks · 150 words Science & TechnologyGeneral Studies Paper III 07 When AI Risks Outpace Safeguards — Classifiers, Dual-Use Knowledge and the Case for Controlling Access GS-III · S&T — AI, Dual-Use Technology; Security — CyberGS-II · IR — Export Control RegimesPrelims + MainsThe Hindu · Explainer A 10 September report by Anthropic described blocking users of its Claude models for potentially harmful activity in cybersecurity, surveillance and biotechnology between December 2025 and August 2026. The explainer asks what AI “safeguards” can actually guarantee. ◈ Static Background — From the Basics Dual-use technology — knowledge or items with both civilian and military/harmful applications. A control loop in code, for instance, runs air-conditioners as well as missile guidance. Input and output classifiers — separate AI filters that screen a user’s prompts and the model’s responses for harmful content, such as help with biological or chemical weapons. False positives vs false negatives: a strict filter blocks legitimate researchers; a lenient one lets misuse through. The report itself notes a classifier cannot both fully enable benefit and fully prevent harm where knowledge is dual-use. Gain-of-function research — work that enhances a pathogen’s transmissibility or virulence, usually to study risk; it is among the most tightly regulated areas of life science. Export-control regimes: CoCom (1949–1994, Cold War); today the Wassenaar Arrangement (conventional and dual-use goods), Nuclear Suppliers Group, Missile Technology Control Regime and Australia Group (chemical-biological). India’s memberships: MTCR (2016), Wassenaar Arrangement (2017), Australia Group (2018); India is not yet a member of the NSG. What the Explainer Says Candid admissions: as reported, Anthropic’s earlier models had less stringent biology safeguards because internal evaluations judged them less capable, and some filters had been inactive on about 133 million exchanges for nearly a year. Case studies: examples included a user drafting a gain-of-function grant proposal on the chikungunya virus, and developers using AI-written code in a guided rocket programme; accounts were terminated once misuse became clear. “Exfiltration before termination”: a user may already have saved outputs offline before being detected, so “safeguards” can act on harm without preventing it entirely. Pattern, not single messages: using a “rifle or wheelchair” analogy, the author explains that harmful intent often becomes visible only as a sequence of individually innocent requests accumulates. Lessons From Older Control Systems Control who, not each item: export-control regimes rarely inspect individual shipments; they rely on licences, end-user and end-use certificates and lists of barred entities. Monitor patterns: anti-money-laundering systems, controls on large ammonium nitrate purchases after the 1995 Oklahoma City bombing, and limits on pseudoephedrine sales combine access limits with tracking over time. AI parallel: “trusted access programmes” — verifying users before granting advanced capabilities — mirror this approach. The Critical View Self-regulation limits: AI firms are largely policing themselves; external audits and independent safety evaluations would make claims verifiable. Access controls have costs: verification can exclude researchers and users in developing countries and concentrate powerful tools among a few actors. Open models: access controls do not apply to openly released model weights, which can be run without any filter. India’s frame: the IndiaAI Safety Institute (announced 2025), the India AI Governance Guidelines and the Digital Personal Data Protection Act, 2023 are building blocks, but no dedicated law yet addresses dual-use AI risks. ✎ Mains Practice Question Content filters alone cannot prevent the misuse of dual-use artificial intelligence. Discuss the limitations of self-regulation by AI developers and examine whether lessons from export-control regimes can inform AI governance. 15 marks · 250 words Environment & EcologyGeneral Studies Paper III 08 India’s Path to Blue Skies — NCAP Progress, Monitoring and the Institutional Architecture Against Air Pollution GS-III · Environment — Pollution, Conservation, Environmental ImpactGS-II · Governance — Statutory BodiesPrelims + MainsPIB Backgrounder · Ministry of Environment, Forest & Climate Change Marking the International Day of Clean Air for Blue Skies (7 September), the Government reports that 108 of 130 NCAP cities recorded lower PM10 levels in 2025-26 than in 2017-18, and 14 cities now meet national standards against 6 in the base year. ◈ Static Background — Part A: The Science of Air Pollution Particulate Matter (PM): a mixture of solid and liquid particles. PM10 has a diameter of 10 micrometres or less (coarse — road dust, construction); PM2.5 is 2.5 µm or less (fine — combustion, secondary aerosols). Why size matters: PM10 lodges in the nose, throat and upper airways; PM2.5 penetrates deep into the lungs and bloodstream, linked to heart disease, stroke and lung cancer. Primary vs secondary pollutants: primary are emitted directly (soot, SO₂); secondary form in the air — ground-level ozone from NOₓ and VOCs in sunlight, and secondary PM from SO₂, NOₓ and ammonia. Winter smog in north India: temperature inversion and low wind speeds trap pollutants near the ground, while the land-locked Indo-Gangetic Plain limits dispersal. NAAQS (2009): 12 pollutants; annual limits PM10 — 60 µg/m³, PM2.5 — 40 µg/m³. The WHO Air Quality Guidelines (2021) are far stricter: annual PM2.5 — 5 µg/m³, PM10 — 15 µg/m³. Figure 6 — How Small Is Particulate Matter? A human hair is roughly 50–70 µm thick — several PM10 particles, and many more PM2.5 particles, fit across its width. Image courtesy PIB (source: Ministry of Health & Family Welfare); reproduced with credit for educational use. ◈ Static Background — Part B: Laws and Institutions Air (Prevention and Control of Pollution) Act, 1981 — enacted under Article 253 to implement decisions of the 1972 Stockholm Conference; empowers States to declare air pollution control areas. CPCB — a statutory body constituted in 1974 under the Water (Prevention and Control of Pollution) Act, 1974, with functions under the Air Act, 1981; SPCBs and Pollution Control Committees (in UTs) implement at State level. Environment (Protection) Act, 1986 — umbrella law passed after the Bhopal gas tragedy; industrial emission standards are notified under its 1986 Rules. Decriminalisation: the Jan Vishwas (Amendment of Provisions) Act, 2023 replaced imprisonment with monetary penalties for many Air Act offences; the Water (Amendment) Act, 2024 did the same for water. CAQM — the Commission for Air Quality Management in NCR and Adjoining Areas Act, 2021 created a statutory airshed body; it replaced the Environment Pollution (Prevention and Control) Authority (EPCA), set up in 1998 on the Supreme Court’s direction. Constitutional anchors: Article 21 (right to a healthy environment, as interpreted by courts), Article 48A (DPSP) and Article 51A(g) (Fundamental Duty). ▤ NCAP at a Glance Launched: January 2019 by MoEFCC, covering 130 cities — mostly non-attainment cities that failed NAAQS for five consecutive years, plus million-plus cities. Target: initially 20–30% PM10 reduction by 2024 (base 2017-18); revised to up to 40% reduction or meeting NAAQS by 2025-26. Funding: NCAP funds and XV Finance Commission air-quality grants for million-plus cities, linked to performance. Tracking: PRANA portal for physical and financial progress; Swachh Vayu Survekshan (from 2022-23) ranks cities annually. Monitoring (March 2026): 1,646 stations in 603 cities across 28 States and 7 UTs — manual and CAAQMS (Continuous Ambient Air Quality Monitoring Stations); SAMEER app gives AQI for 292+ cities. Results (2025-26 vs 2017-18): 108 cities reduced PM10; 72 by over 20%; 26 by over 40%; cities meeting NAAQS rose from 6 to 14.

From the Basics — The Air Quality Index and GRAP The National AQI (launched April 2015) converts concentrations of eight pollutants — PM10, PM2.5, NO₂, SO₂, CO, O₃, NH₃ and Pb — into one number. The worst-performing pollutant sets the overall AQI, across six categories. Figure 8 — AQI Categories and the Four Stages of GRAP (Delhi-NCR) GoodSatisfactoryModerately pollutedPoorVery poorSevere0–5051–100101–200201–300301–400401–500GRAP Stage IAQI 201–300Stage IIAQI 301–400III401–450IV> 450Stage I: dust control, ban on open burning · Stage II: curbs on diesel generators, higher parking feesStage III: construction and older-vehicle restrictions · Stage IV (Severe+): entry curbs on trucks, work-from-home advisories GRAP is triggered on actual or forecast AQI, so action can begin before air quality crosses a threshold. Figure 9 — How Air Quality Is Monitored A CAAQMS station samples air through an inlet and records meteorological data; readings feed the AQI shown on apps such as SAMEER. Image courtesy PIB Backgrounder (AI-generated illustration); reproduced with credit for educational use. Sector-Wise Measures Vehicles: BS-VI nationwide from April 2020 (leapfrogging BS-V); PM E-DRIVE and PM e-Bus Sewa; Vehicle Scrapping Policy with RVSFs and Automated Testing Stations; PARIVARTAN to replace BS-IV and older trucks and buses in NCR; only BS-VI/CNG/EV buses to enter Delhi from 1 November 2026; electric-only L5 three-wheelers in Delhi and phased NCR rollout. Industry: CPCB classifies 419 sectors — 125 Red, 137 Orange, 94 Green, 54 White, 9 Blue; OCEMS for 17 highly polluting categories; CAQM’s revised PM norm of 50 mg/Nm³ from 1 October 2026; CEPI-based Critically and Severely Polluted Areas; CPCB IV+ standards (2022) for gensets up to 800 kW. Dust: anti-smog guns at construction sites over 20,000 sq m; 70 Dust Control and Management Cells in NCR; online monitoring for sites above 500 sq m. Waste burning: waste rules (Solid Waste Rules revised 2026); EPR for plastic, e-waste, batteries, tyres and used oil; ban on 12 single-use plastic items from 1 July 2022. Crop residue: ₹4,233.84 crore (2018-19 to 2025-26); 3.53 lakh machines and 43,535 Custom Hiring Centres; 5–10% biomass co-firing in thermal plants within 300 km of Delhi; stubble-burning incidents down 93% in Punjab and 91% in Haryana in 2025 versus 2021 (Government data). Regulatory reform: uniform Consent Guidelines, 2025 under the Air and Water Acts (January 2025) and the UCAMS online consent portal. The Critical View PM10, not PM2.5: NCAP targets are set on PM10, which is dominated by dust; the more harmful PM2.5 from combustion may fall more slowly. Standards gap: even compliant cities meet NAAQS, which are many times looser than WHO 2021 guidelines. Spending mix: independent reviews have found a large share of city funds going to road-dust measures, with less on vehicular, industrial and household combustion sources. Weather and baseline effects: year-to-year changes can reflect rainfall and wind; cross-year comparisons need meteorological normalisation. Airshed problem: pollution crosses city and State lines; outside NCR, there is no CAQM-like regional body for the wider Indo-Gangetic Plain. Enforcement: SPCBs face staff shortages, and decriminalised penalties must be enforced consistently to deter violations. ✎ Mains Practice Question The National Clean Air Programme has recorded progress, yet most Indian cities continue to breach air-quality standards. Critically evaluate NCAP’s design and outcomes, and suggest how an airshed-based approach could improve air-quality governance. 15 marks · 250 words 09 Himalaya Near a Tipping Point — Accelerating Glacier Melt Pushes the Region Towards “Peak Water” by Mid-Century GS-I · Geography — Glaciers, Himalayan DrainageGS-III · Environment — Climate Change; Disaster ManagementPrelims + MainsThe Hindu · Science & Environment A new study warns that Himalayan glaciers are melting faster than a decade ago, with river flows expected to reach “peak water” by mid-century — weeks after a glacier collapse on the Nepal–Tibet border triggered deadly floods and landslides. ◈ Static Background — From the Basics Hindu Kush Himalaya (HKH): spans eight countries — Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, Pakistan. It holds the largest ice reserves outside the poles, hence the “Third Pole”, and feeds rivers such as the Indus, Ganga and Brahmaputra. Glacier mass balance = snow accumulation − melt and ice loss. A negative balance year after year means the glacier is shrinking. Peak water: as warming speeds up melting, meltwater runoff first rises. Once the glacier has shrunk enough, runoff peaks and then declines, even if warming continues. GLOF (Glacial Lake Outburst Flood): retreating glaciers leave moraine-dammed lakes held by loose rock and ice; a breach releases sudden floods. NDMA issued GLOF guidelines in 2020. Recent Indian disasters: Chamoli, Uttarakhand (February 2021) — a rock-and-ice avalanche; South Lhonak lake GLOF, Sikkim (October 2023) — destroyed the Teesta-III (Chungthang) dam. Institutions: ICIMOD (Kathmandu, 1983); G.B. Pant National Institute of Himalayan Environment (Almora, under MoEFCC); National Mission for Sustaining the Himalayan Ecosystem — one of the eight missions of the NAPCC (2008). ▤ The Study and the Numbers Authors: Systemiq with the Integrated Mountain Initiative, ICIMOD and India’s G.B. Pant National Institute of Himalayan Environment. Monitoring gap: only 21 glaciers are monitored on the ground out of an estimated 40,000 in the HKH. Economic stake: the Himalaya underpin more than 20% of India’s GDP, according to the study. Disaster share: the Himalayan region covers about 18% of India’s land but accounts for roughly 35% of its natural disasters. Recent collapse: a glacier collapse in late August along the Nepal–Tibet border caused cascading landslides and flash floods; at least 1,300 were confirmed dead and over 5,300 missing, as reported. Earlier evidence: ICIMOD’s 2023 assessment found HKH glaciers lost ice 65% faster in 2011–2020 than in the previous decade. Figure 10 — The “Peak Water” Curve (conceptual) Time → (continued warming)Glacier meltwater runoffPeak waterRising runoffDeclining flowHKH: projected around mid-centuryMeltwater runoffGlacier ice volume Rising melt first masks the problem with more water; after the peak, dry-season flows fall as ice reserves shrink. Schematic, not to scale. Why It Matters for India Water security: glacier melt sustains dry-season flows in Himalayan rivers that support irrigation, drinking water and hydropower across the Indo-Gangetic Plain. Hydropower risk: dams in high valleys face both GLOF hazards and long-term changes in flow that affect their economics. Disaster exposure: unstable glacial lakes above populated valleys raise the risk of cascading disasters — landslides, debris flows and floods. Transboundary dimension: the Brahmaputra and Sutlej originate in Tibet, and the Indus is shared with Pakistan; data sharing on glacial hazards is a diplomatic as well as scientific need. The Critical View and Way Forward Data deficit: with 21 of about 40,000 glaciers monitored on the ground, hazard mapping relies heavily on satellite estimates; ground stations and early-warning systems need rapid expansion. Development pressure: roads, tunnels and dams in fragile slopes need cumulative impact assessment and carrying-capacity studies, as courts and expert panels have repeatedly urged. Early warning: the 2023 Sikkim disaster showed how gaps in lake monitoring and warning can magnify losses downstream.

Definition: a person who uses expertise and reasoned argument to engage the public on social, political and economic questions, reaffirming values such as justice, dignity and fraternity. Antonio Gramsci distinguished “traditional” from “organic” intellectuals, who emerge from and articulate the interests of social groups; the author cites his essay “I Hate the Indifferent” (1917). Indian tradition: the author traces a line of questioning thinkers from the Buddha to B.R. Ambedkar. Constitutional value: Article 51A(h) — the duty to develop scientific temper, humanism and the spirit of inquiry and reform. The Author’s Argument Silence of experts: the author contends that many university teachers and scientists confine themselves to narrow specialisations and avoid public debate on issues affecting the marginalised. Decline of informed debate: the author says scholarly voices have largely disappeared from television debates, which now reward noise over substance. History and myth: the author urges historians to challenge the blurring of myth and history in popular circulation. Youth engagement: citing recent largely peaceful youth protests over examination lapses, the author argues young people are not depoliticised and raised a basic question of accountability. ▤ Ethics Toolkit Values: courage of conviction, intellectual honesty, objectivity, tolerance of opposing views, responsibility for the consequences of speech. Tensions: academic freedom vs institutional neutrality; advocacy vs objectivity; dissent vs public order; a civil servant’s political neutrality vs a citizen’s voice. Thinkers: Socrates (“the unexamined life is not worth living”); Gandhi’s truth-force and non-violent dissent; Ambedkar’s warning in the Constituent Assembly against the “grammar of anarchy” once constitutional methods exist. Balanced reading: constructive criticism strengthens democracy, but public intellectuals also carry a duty to be fair, evidence-based and non-partisan — criticism should target ideas and policies, not persons or communities. ✎ Mains Practice Question (Case-Based) A senior professor at a public university is asked by students to speak publicly on a controversial policy that she believes violates constitutional values. Her colleagues warn it may affect the university’s funding and her career. What ethical considerations should guide her decision?
