Tax is collected at each stage, but each business deducts the tax already paid on its purchases — the input tax credit (ITC) — so that only the value added is taxed and cascading (tax on tax) is avoided. Dual structure — on an intra-State supply, the Centre levies CGST and the State levies SGST/UTGST; on an inter-State supply, the Centre levies IGST, later apportioned. Inverted duty structure (IDS) — when inputs are taxed at a higher rate than the output, unused ITC piles up; the law allows a refund of it. Zero-rated supplies — exports and supplies to SEZs (Section 16, IGST Act) bear no GST; the supplier can claim refund of ITC or of IGST paid. Reverse charge mechanism (RCM) — the recipient, not the supplier, pays the tax on notified supplies. ◈ Static Background — The Constitutional Architecture 101st Constitutional Amendment Act, 2016 — inserted Article 246A (concurrent power of Parliament and State legislatures to levy GST; inter-State supplies exclusively with Parliament), Article 269A (IGST and its apportionment) and Article 279A (GST Council). GST Council (Article 279A) — chaired by the Union Finance Minister, with the Union MoS (Revenue/Finance) and the Finance Ministers of all States and UTs with legislatures. Voting — decisions need a three-fourths majority of weighted votes of members present and voting; the Centre’s vote carries one-third weight and the States together two-thirds. Neither side can carry a decision alone. Nature of recommendations — in Union of India v. Mohit Minerals (2022), the Supreme Court held that Council recommendations have persuasive value and are not binding; Parliament and the States legislate independently. Laws — CGST Act, IGST Act, UTGST Act, the SGST Acts of each State and the GST (Compensation to States) Act — all of 2017. ▤ Decision at a Glance Body: GST Council, 57th meeting, New Delhi, 8 October 2026; chaired by the Union Finance Minister. Focus: process reforms — registration, returns, refunds, adjudication — plus rate clarifications and trade facilitation. Legal route: recommendations take effect only through amendments to the CGST/IGST Acts, rules, notifications and circulars. Key dates: refund of ITC on input services (IDS) for ITC availed from 1 November 2026; refund of ITC on capital goods spread over 60 months, for ITC availed from 1 April 2027; new return-amendment mechanism from the April 2027 return. Small taxpayers: in-principle nod to an optional Annual Return Quarterly Payment (ARQP) scheme for B2C businesses with turnover up to ₹5 crore; late-fee waiver for the same turnover band if the return is filed within the due month. A. Registration and Returns Registration — a comprehensive circular and drop-down lists in FORM GST REG-01; automatic acceptance of amendments to registration particulars (except the Principal Place of Business, for regular registrants). Cancellation — automatic acceptance of a taxpayer’s cancellation request once returns are filed and dues paid; system-based suo motu cancellation and revocation for non-filing. E-commerce sellers — new rule 14B: small sellers can register in another State by declaring the e-commerce operator’s warehouse as their place of business, without a physical presence there. Returns — new electronic statements for reverse-charge ITC and credit reversal/reclaim; a mechanism to align GSTR-3B with GSTR-1 and GSTR-2B, and a defined window for keeping credit notes pending on the Invoice Management System (IMS). A public consultation precedes roll-out. B. Refunds and the Flow of Credit Automatic refunds — full refund of excess electronic cash ledger balance without officer intervention; 90% of claims for exports and IDS sanctioned provisionally by the system on a risk basis (Phase 1); full automated sanction for zero-rated claims (Phase 2). Timelines — acknowledgement within 10 days (from 15), with deemed acknowledgement if the officer does not act. IDS refund widened — ITC on input services and capital goods becomes refundable. Earlier, rule 89(5) confined IDS refunds to inputs (goods) — a restriction upheld by the Supreme Court in VKC Footsteps (2021). Blocked credits eased (Section 17(5)) — ITC now allowed on items such as outdoor catering, health and life insurance, telecom towers, pipelines outside factory premises and free samples, reducing cascading. Export of services — supplies to a company’s own foreign branch can now qualify as exports; delivery to an overseas buyer inside an SEZ/FTWZ treated as a zero-rated supply to an SEZ. C. Disputes, Penalties and Enforcement Arrest powers withdrawn — omission of Section 69 of the CGST Act. (The Supreme Court had upheld these powers in Radhika Agarwal v. Union of India, 2025, while laying down safeguards.) Prosecution (Section 132) — threshold raised from ₹1 crore to ₹5 crore; offences narrowed to the core of fraudulent ITC (credit without goods, services or invoice). Notices and penalties — no show-cause notice below ₹10,000 of tax (applied to pending cases too); maximum general penalty (Section 125) cut from ₹25,000 to ₹10,000; 5% penalty in non-fraud cases if dues are paid within 30/60 days of the order. Appeals — pre-deposit in penalty-only cases capped at ₹40 crore (₹20 crore CGST + ₹20 crore SGST); GSTAT provisions aligned with the new tribunal-reform legislation. E-way bills — vehicles intercepted only on specific intelligence with authorisation of an officer not below Joint Commissioner; no interception in transit States; confiscation not applicable to goods in transit (except where no e-way bill or documents exist). Figure 1 — The Compliance and Enforcement Shift: Before and After the 57th Meeting ProvisionBeforeAfter (recommended)Arrest powers (s. 69)Prosecution threshold (s. 132)Maximum general penalty (s. 125)Minimum tax for a show-cause noticeRefund acknowledgementProvisional refund (exports, IDS)ITC on input services in IDS refundE-way bill interceptionAvailable to officers₹1 crore₹25,000No statutory floor15 daysOfficer-processedExcluded (rule 89(5))Any State, incl. transitOmitted₹5 crore₹10,000₹10,000 (pending cases too)10 days; deemed if not issued90% auto-sanctioned, risk-basedRefundable (ITC from 1 Nov 2026)Only on intelligence; not in transitRecommendations take effect only after amendment of the CGST/IGST Acts, rules and notifications The common thread is less officer discretion and more system-based processing — while keeping prosecution for fake-invoice ITC fraud. D. Rate Clarifications Worth Noting Circular economy — plastic waste, e-waste, waste tyres and used cooking oil supplied by unregistered persons brought under RCM; 2% TDS on B2B supplies of such scrap — to formalise a largely informal trade. Electric mobility — optional 5% GST (with restricted ITC) on passenger transport and vehicle rental using EVs where charging cost is included. Platform economy — delivery services through e-commerce operators by unregistered persons brought under Section 9(5) at 5% without ITC. Exemptions — shared-seat helicopter travel to/from the North-East, Sikkim and Bagdogra; storage of seeds for sowing; curing of coffee; NIL rate on psyllium (isabgol) seeds; upfront payments to NHAI under the Toll-Operate-Transfer (TOT) model. Lineage — How GST Has Evolved 2017 — launch with multiple slabs (0, 5, 12, 18, 28% plus compensation cess). 2018–2024 — e-way bill system, QRMP scheme for small taxpayers (2021), e-invoicing phased down to ₹5 crore turnover, IMS for invoice matching. 56th meeting (2025) — “next-generation” rate rationalisation, moving most goods to two main slabs. 57th meeting (2026) — process simplification, decriminalisation and automation; continues the logic of the Jan Vishwas (Amendment of Provisions) Act, 2023, which decriminalised minor offences across central laws. The Critical View Deterrence vs trust — fake-invoice ITC fraud remains GST’s biggest leakage; removing arrest powers and lifting the prosecution threshold must be matched by strong data analytics and recovery tools. Automation risk — system-sanctioned refunds speed up cash flow but can be gamed; outcomes depend on the quality of risk-scoring and GSTN data. Federal angle — barring interception in transit States limits State enforcement reach; implementation requires Parliament and every State legislature to amend their GST laws. Revenue cost — wider ITC and refunds lower effective collections in the short run, though they reduce cascading and improve export competitiveness. Implementation gap — several measures depend on future circulars, portal changes and time-bound consultation; dates stretch to 2027. ✎ Mains Practice Question “The second phase of GST reform is about process, not rates.” Discuss with reference to the recent recommendations of the GST Council, and examine how a trust-based compliance regime can be balanced against the need to deter tax evasion. 15 marks · 250 words Social Justice & Inclusive GrowthGeneral Studies Papers II & III 02 National SC-ST Hub Completes a Decade: Linking SC/ST Entrepreneurs to Credit, Skills and Government Markets ImportantGS-II · Social Justice — Welfare Schemes for Vulnerable Sections · GS-III Inclusive Growth, MSMEsPrelims + MainsPIB Backgrounder · Ministry of MSME · 8 October 2026 Launched on 18 October 2016 and implemented by the National Small Industries Corporation (NSIC), the National SC-ST Hub (NSSH) turns ten this month. Its core idea is to use public procurement as a market for SC/ST-owned micro and small enterprises, backed by skills, credit-linked subsidy and marketing support. ◈ Basics First — Why Enterprise Ownership Matters Inclusion through wage employment and reservation in jobs leaves untouched the deeper gap in ownership of capital and enterprises. SC/ST entrepreneurs have historically faced thin collateral, weak business networks, limited access to formal credit and to buyers. A guaranteed share of government purchases can give such firms their first stable market. Constitutional basis — Article 46 (DPSP): the State shall promote the educational and economic interests of SCs, STs and weaker sections; SCs and STs are notified under Articles 341 and 342. MSME definition (revised with effect from April 2025) — micro: investment up to ₹2.5 crore, turnover up to ₹10 crore; small: up to ₹25 crore / ₹100 crore; medium: up to ₹125 crore / ₹500 crore. Registration is on the Udyam portal. NSIC — a Central PSU under the Ministry of MSME, set up in 1955. ▤ Scheme at a Glance Launched: 18 October 2016. Nodal Ministry: Ministry of Micro, Small and Medium Enterprises; implementing agency: NSIC. Policy anchor: Public Procurement Policy for MSEs Order, 2012 (under the MSMED Act, 2006) — Central Ministries, Departments and CPSEs must procure 25% of annual purchases from MSEs, with 4% earmarked for SC/ST-owned MSEs (and 3% for women-owned MSEs). Coverage (to 31 July 2026): 1,90,414 beneficiaries assisted; 54,499 candidates trained. Procurement from SC/ST MSEs: ₹99.37 crore (2015-16) → ₹4,013.42 crore (2025-26) from 12,524 MSEs — about 40 times the 2015-16 level. Leading States: Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Assam. Figure 2 — NSSH: Key Impact Numbers Procurement data are the scheme’s headline outcome; they measure market access, not firm survival or profitability. Image courtesy PIB / Ministry of MSME; reproduced with credit for educational use. The Toolkit — Support Across the Enterprise Life Cycle Special Credit Linked Capital Subsidy Scheme (SCLCSS) — 25% capital subsidy (capped at ₹25 lakh) on plant and machinery bought with institutional credit; 3,160 MSEs supported (₹356.10 crore) across 233 districts up to March 2026. Single Point Registration Scheme (SPRS) — NSIC registration gives free tender sets and exemption from Earnest Money Deposit. Special Marketing Assistance Scheme (SMAS) — trade fairs, vendor development programmes with CPSEs, e-tendering workshops; support for up to four domestic and two international events a year. Reimbursements — 80% (up to ₹1 lakh) of loan processing fees, bank guarantee charges and BIS testing fees; Export Promotion Council membership; 90% of fees for short courses at top-50 NIRF management institutes; membership of GeM, e-Khadi, TRIFED/Tribes India and MSME Mart. Business Accelerator Programme — mentoring on strategy, pricing and operations. Figure 3 — NSSH Capacity-Building Pillars In 2025-26, 10,717 candidates were trained through 47 institutions in 27 States, including 24 Aspirational Districts; 55% were women. Image courtesy PIB / Ministry of MSME; reproduced with credit for educational use. Lineage — Related Measures for SC/ST Enterprise Public Procurement Policy for MSEs (2012) — the overall MSE target was raised from 20% to 25% in 2018; the 4% SC/ST sub-target has applied throughout. Stand-Up India (2016) — bank loans of ₹10 lakh to ₹1 crore for greenfield enterprises, to at least one SC/ST and one woman borrower per bank branch. Venture Capital Fund for SCs (2014-15) and the Credit Enhancement Guarantee Scheme for SCs, under the Ministry of Social Justice. Union Budget 2025-26 — announced term loans up to ₹2 crore for 5 lakh first-time women, SC and ST entrepreneurs. The Critical View Target vs achievement — the 4% sub-target has historically been met by relatively few Ministries and CPSEs; absolute growth in procurement does not by itself show the share achieved. Proxy ownership — the risk of enterprises being nominally SC/ST-owned to capture procurement benefits calls for verification. Regional concentration — benefits cluster in industrialised States; reach in tribal and remote districts remains thin. Delayed payments — MSE working capital suffers when buyers pay late, despite the 45-day payment norm under the MSMED Act and MSME Samadhaan. Outcome data — beneficiary and training counts measure outputs; firm survival, growth and job creation need independent evaluation. ✎ Mains Practice Question Public procurement can be a powerful lever for inclusive entrepreneurship. Evaluate the performance of the National SC-ST Hub in its first decade and suggest measures to deepen the participation of SC/ST entrepreneurs in the MSME ecosystem. 15 marks · 250 words

01 An Adequate Response? The RBI’s Rate Hike, Supply-Side Inflation and the Government’s Share of the Burden Core TopicEditorialGS-III · Economy — Monetary Policy, Inflation, Food ManagementPrelims + MainsThe Hindu · Editorial The editorial accepts the MPC’s 25-bps hike and shift to “calibrated tightening” as a sound move, but argues that when inflation is driven by oil prices and a deficient monsoon, interest rates can only work at the margin — chiefly by anchoring expectations. The main work, it contends, now lies with the Government’s supply-side tools. ◈ Basics First — Not All Inflation Is Alike Inflation is a sustained rise in the general price level. Its source determines which policy tool works. Monetary policy acts mainly on aggregate demand; it cannot produce more oil or vegetables. Demand-pull inflation — too much spending chasing limited output; interest-rate hikes are effective because they cool credit-financed demand. Cost-push (supply-side) inflation — rising input costs or supply shocks (crude oil, crop failure); rate hikes reduce output further without fixing supply. Imported inflation — higher world prices or a weaker rupee raise the cost of imports such as crude oil and edible oils. Headline vs core — headline CPI includes volatile food and fuel; core inflation excludes them and signals underlying demand pressure. Inflation expectations — if households and firms expect higher prices, they demand higher wages and set higher prices, making inflation self-fulfilling. The RBI tracks them through its Inflation Expectations Survey of Households. Static Background — The Framework in Brief Flexible Inflation Targeting (FIT) — statutory since the RBI Act amendment of 2016; target 4% CPI with a tolerance band of 2–6%. Missing the band for three consecutive quarters counts as a failure, and the RBI must report reasons and remedies to the Centre. “Flexible” means the MPC must also keep growth in view — the classic growth–inflation trade-off. Fuel pricing — petrol prices were deregulated in 2010 and diesel in 2014; in practice, oil marketing companies (OMCs) often hold retail prices steady during spikes, absorbing losses that eventually burden public finances. Figure 1 — RBI’s CPI Inflation Projections for 2026-27 against the Target Band 6% upper4% target2% lower0%4.9%6.0%5.7%Q2 (Jul–Sep)Q3 (Oct–Dec)Q4 (Jan–Mar)Aug proj. 4.7%Shaded: 2–6% tolerance band · projections as cited in the editorial Projected inflation climbs to the upper edge of the band in Q3 — the context for a pre-emptive hike aimed at expectations rather than at the oil and food shocks themselves. The Editorial’s Argument The drivers are on the supply side — crude has crossed $100 a barrel again, and a deficient monsoon is pushing up food prices; OMCs have so far held back most of the fuel-price increase. A rate hike works at the margin — against supply shocks it has only second-order effects; it is “a careful nudge rather than an ineffectual bludgeon”. The signal matters most — the stance change to calibrated tightening tells markets that the question is no longer whether rates rise in December but by how much. Growth confidence — the RBI raised its 2026-27 GDP forecast to 7.1% (from 6.7%), though most agencies foresee a second-half slowdown. External side — higher rates may slow the exit of Foreign Portfolio Investors, giving the rupee some relief. The onus shifts to the Government — to use its food-management and supply tools more effectively. ◈ The Government’s Supply-Side Toolkit Buffer stocks — FCI stocks of wheat and rice; the Price Stabilisation Fund (2014-15) for pulses and onions. Open Market Sale Scheme (OMSS) — the FCI sells grain from central stocks in the open market to cool prices (distinct from the RBI’s open market operations in bonds). Trade measures — cutting import duties (e.g. on edible oils) and restricting exports. Anti-hoarding — stock limits on traders under the Essential Commodities Act, 1955. Fiscal levers — adjusting excise duty on petrol and diesel to cushion retail prices. Critical Assessment Strength — the editorial rightly identifies expectations management as the real channel of monetary policy during supply shocks; un-anchored expectations can turn a temporary shock into persistent inflation. Lag effect — monetary policy acts with a lag of several quarters; by the time it bites, the oil or food shock may have reversed, needlessly slowing growth. Trade-offs in supply tools — export bans and stock limits hurt farm incomes and India’s reputation as a reliable exporter; duty cuts cost revenue. Fiscal–monetary coordination — suppressed fuel prices delay inflation but transfer the cost to OMC balance sheets and the fiscal deficit; transparency about who bears the shock is needed. ✎ Mains Practice Question “When inflation is driven by supply shocks, monetary tightening is a necessary signal but an insufficient remedy.” Discuss with reference to the recent policy action of the RBI, and suggest the fiscal and administrative measures that should complement it. 15 marks · 250 words ExplainedConcept Explainers · Agriculture, Energy & Trade 02 Why Edible Oils Lead Food Inflation: Biodiesel Mandates, El Niño and Black Sea Disruptions Core TopicExplainedGS-III · Economy — Agriculture, Food Security, Energy · GS-I Geography (El Niño)Prelims + MainsThe Indian Express · Explained The FAO Food Price Index averaged 136 points in September 2026, its highest since November 2022; within it, the vegetable oil index hit 198.6. The explainer traces this to three converging forces — biofuel mandates that divert oil from food to fuel, an intensifying El Niño, and the Russia–Ukraine war choking Black Sea exports. ◈ Basics First — Vegetable Oils, Biodiesel and Price Indices Major vegetable oils — palm (from the oil palm fruit), soybean, rapeseed/canola and sunflower. Indonesia and Malaysia together produce the large majority of the world’s palm oil. Biodiesel (FAME) — vegetable oils are converted into Fatty Acid Methyl Esters by transesterification: the oil’s triglycerides react with methanol in the presence of a catalyst, yielding FAME and glycerol as a by-product. FAME can be blended with petroleum diesel. Blending notation — B20 means diesel with 20% biodiesel; similarly, E20 is petrol with 20% ethanol. FAO Food Price Index — compiled by the Food and Agriculture Organization (founded 1945, HQ Rome); base 2014–16 = 100; five sub-indices: cereals, vegetable oils, dairy, meat and sugar. Figure 2 — The Vegetable Oil Price Cycle and Indonesia’s Palm Oil Balance After the post-invasion spike (251.8, March 2022) and a slump, prices have climbed again since 2024. Image courtesy The Indian Express, October 2026 (sources: FAO; GAPKI); reproduced with credit for educational use. Force 1 — Food-to-Fuel Diversion Biofuel mandates compel fuel retailers to blend a minimum share of biofuel, creating a guaranteed, price-insensitive demand for vegetable oils. Industry estimates put roughly a quarter of world soybean oil and over a quarter of palm and rapeseed oil into biodiesel. High crude prices — Brent above $100 — make diversion even more attractive. Indonesia — the world’s largest palm oil producer and the first country to mandate 50% blending (B50, July 2026). Its biodiesel use of palm oil is projected to rise from 12.7 mt (2025) to 17.4 mt (2027), while exports may fall from 32.3 mt to 26.5 mt. Malaysia — B10 nationwide since September 2019; phased roll-out of B15 from June 2026. United States — about 8.07 mt (54%) of a projected 14.94 mt soybean oil output in 2026–27 directed to biofuels. European Union — about 6.1 mt (57.2%) of 10.67 mt rapeseed oil diverted to biodiesel and bio-ATF. Figure 3 — Indonesia’s Biodiesel Blending Staircase B20B20B30B35B40B502016Sep 2018Jan 2020Aug 2023Jan 2025Jul 2026limited scalenationwideworld’s first B50Malaysia: B10 nationwide (Sep 2019) → phased B15 (from Jun 2026) Each step up the staircase absorbs more palm oil at home; B40 → B50 alone is projected to take an extra 4.7 mt off the export market. Force 2 — El Niño What it is — the warm phase of the El Niño–Southern Oscillation (ENSO): unusual warming of the central and eastern equatorial Pacific, which weakens the trade winds and shifts rainfall patterns. Typical effects — drier conditions over Indonesia, Malaysia and Australia, and a tendency towards a weaker Indian monsoon. Current episode — already “very strong”, expected to peak in October–December and persist till March–April. Lagged impact on palm — water-stressed oil palms abort female flowers and young fruit bunches, so yields fall 8–12 months later; Indonesia’s output is projected to dip from 58.5 mt (2026) to 56.6 mt (2027). Force 3 — War and Logistics Russia and Ukraine are the world’s two leading sunflower producers; their 2026–27 crops are larger (21 mt and 13 mt of seed), but exports are blocked. Navigation through the Sea of Azov (linked to the Black Sea by the Kerch Strait) has stopped since 10 July, and Black Sea port operations are suspended; alternatives via the Baltic, Caspian, Far East or rail are costly and congested. Static peg: the UN- and Türkiye-brokered Black Sea Grain Initiative (July 2022 – July 2023) had earlier kept Ukrainian exports moving. The India Angle — The World’s Largest Edible Oil Importer India depends on imports for close to two-thirds of its edible oil consumption. Domestic production is estimated to fall from 9.7 mt (2025-26) to 9.2 mt (2026-27) because of El Niño, pushing imports to a record 17.2 mt — about 8.2 mt palm, 5 mt soybean and 3.5 mt sunflower oil. Figure 4 — India’s Edible Oil Supply: Domestic Output vs Imports 2025-262026-27 (est.)Domestic 9.7 mtImports 16.8 mt (≈63%)Domestic 9.2 mtImports 17.2 mt (≈65%) — recordImport share computed from the trade estimates cited (domestic + imports = total supply) A small fall in domestic output translates into a record import bill just as landed prices of palm, soybean and sunflower oil rise. ◈ Static Background — India’s Oilseed Policy Nine annual oilseeds — groundnut, rapeseed-mustard, soybean, sunflower, sesame, safflower, niger, castor and linseed; mostly rain-fed, hence monsoon-sensitive. Yellow Revolution — the Technology Mission on Oilseeds (1986) made India nearly self-sufficient by the early 1990s, before import liberalisation reversed the trend. National Mission on Edible Oils — Oil Palm (2021) — outlay ₹11,040 crore, focus on the North-East and Andaman & Nicobar Islands. National Mission on Edible Oils — Oilseeds (2024) — outlay ₹10,103 crore for 2024-25 to 2030-31, targeting a sharp rise in primary oilseed output by 2030-31. India’s own biofuel policy — the National Policy on Biofuels (2018, amended 2022) targets 5% biodiesel blending in diesel by 2030, with feedstock drawn mainly from non-edible oils and used cooking oil. Critical Assessment Food vs fuel — producer countries pursue energy security and lower oil-import bills; importers bear higher food prices. Biofuel policy is thus also trade policy. Vulnerability of concentrated sourcing — India’s reliance on two palm suppliers and on Black Sea sunflower oil exposes household budgets to decisions and conflicts abroad. Policy dilemma at home — lowering import duties eases consumer prices but depresses prices for domestic oilseed farmers, undermining the self-reliance missions. Way forward — higher-yield oilseed varieties, assured procurement and price support, area expansion under oil palm with ecological safeguards, diversified import sources, and promoting non-food feedstocks for biodiesel. ✎ Mains Practice Question “Biofuel mandates in producer countries are turning edible oil into an energy commodity.” Examine how this, along with climatic and geopolitical factors, affects India’s food security, and suggest a strategy to reduce India’s import dependence for edible oils. 15 marks · 250 words

01 Mali’s Army Retakes Kidal: The Tuareg Question, Jihadist Insurgency and Russia’s Role in the Sahel ImportantGS-II · IR — Africa, Effect of Policies of Other Countries · GS-I Places in NewsPrelims + MainsNews reports (Oct 2026) Mali’s armed forces, supported by Russia’s Africa Corps, have reportedly re-entered Kidal after the Tuareg separatist Azawad Liberation Front (FLA) announced a “strategic withdrawal” following heavy air strikes. The town had fallen to separatists and the al-Qaeda-linked JNIM in April 2026. ◈ Basics First — Mali, the Sahel and the Tuareg Mali — a landlocked West African country, former French colony (independent 1960); capital Bamako; the Niger River runs through its centre. The Sahel — the semi-arid belt south of the Sahara, stretching from Senegal to Sudan; marked by drought, weak state presence and armed groups. Kidal — a desert town in the far north-east, near the Algerian border and the Adrar des Ifoghas massif; the political centre of the Tuareg demand for an independent “Azawad”. The Tuareg — a Berber-speaking, traditionally nomadic people spread across Mali, Niger, Algeria and Libya; they rebelled in 1963, 1990, 2006 and 2012. Figure 1 — Mali and the Location of Kidal Kidal lies about 1,500 km north-east of Bamako — closer to Algeria than to the capital. Base geography: Natural Earth 1:10m, public domain. Static Background — A Conflict Timeline 2012 — a Tuareg rebellion declares “Azawad” independent; jihadist groups seize the north; a military coup in Bamako. 2013 — French Operation Serval (later Barkhane, to 2022) and the UN mission MINUSMA (2013–2023) deploy. 2015 — Algiers Peace Agreement with northern armed groups; Mali’s junta terminated it in January 2024. 2020 and 2021 — two coups bring a military government; ties with France rupture and Russian Wagner forces arrive, later replaced by the state-controlled Africa Corps (2025). November 2023 — the army first retook Kidal; separatists regained it in April 2026, before its recapture now. Alliance of Sahel States (AES) — Mali, Burkina Faso and Niger (2023), which left ECOWAS in January 2025. Significance and India Angle Symbolic capital — control of Kidal is a test of the junta’s claim to territorial integrity; separatists retain mobility in the desert. Jihadist threat — JNIM (al-Qaeda) and the Islamic State Sahel Province exploit the conflict; the Sahel has become a leading region for terrorism deaths. Great-power shift — the exit of France and the UN, and the rise of Russia, reshape the region; reported civilian casualties from air strikes raise human-rights concerns. India — interests in the safety of Indian workers (three Indian nationals were kidnapped in western Mali in July 2025), counter-terrorism cooperation, development partnership through lines of credit and ITEC, and access to West African resources. ✎ Mains Practice Question The Sahel has emerged as a hub of separatism, jihadist insurgency and great-power rivalry. Examine the factors behind instability in the region, with reference to Mali, and discuss its implications for India’s Africa policy. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III 02 ARIES-Led Global Study Tracks a Decade of Flickering in OJ 287, a Rare Binary Supermassive Black Hole System ImportantGS-III · S&T — Space, Achievements of Indians in S&TPrelims + MainsPIB · Department of Science & Technology A campaign coordinated by the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital — 106 scientists from 18 countries and 48 institutions, using about two dozen telescopes — has produced the densest optical record of the blazar OJ 287 in 150 years, covering 2015–2025. ◈ Basics First — Black Holes, Quasars and Blazars Supermassive black holes (SMBHs) — of millions to billions of solar masses, sitting at the centres of most large galaxies. Active Galactic Nucleus (AGN) — a galactic centre where matter falling into the SMBH forms a hot accretion disc and can launch relativistic jets of plasma. Blazar — an AGN whose jet points almost directly at Earth; it shows strong, rapidly varying emission from radio waves to gamma rays. Binary SMBH — formed when galaxies merge; two black holes orbit each other and eventually coalesce, releasing gravitational waves. Figure 2 — The Binary Black Hole Model of OJ 287 In the established model, the smaller black hole crosses the bigger one’s accretion disc twice per 12-year orbit, producing double-peaked flares. The illustration’s 18.35-billion-solar-mass primary comes from earlier orbital modelling; the new spectral estimate (≥3.89 billion) is far lower — a live scientific debate. Image as released with the PIB note; reproduced with credit for educational use. Key Findings About OJ 287 — roughly 4 billion light years away; its 12-year double-peaked brightness cycle was identified in 1988 by Finnish astronomers using optical records going back to 1880. Data — the most extensive multiband optical time series of the object, supported by observations across the electromagnetic spectrum. Black hole mass — spectra from the Steward Observatory (USA), using the width of the [O III] emission line, put the central black hole at at least 3.89 billion solar masses. Science gained — tracking the relative positions of the two black holes, changes in brightness, spectrum and polarisation, and searching for emission from the smaller black hole. ▤ Institutions & Terms to Know ARIES, Nainital — autonomous institute of the DST; operates the 3.6-m Devasthal Optical Telescope, India’s largest optical telescope, and the International Liquid Mirror Telescope at Devasthal. Multi-messenger astronomy — studying one source through light, gravitational waves, neutrinos and cosmic rays. Gravitational waves — first directly detected by LIGO in 2015; LIGO-India (Hingoli, Maharashtra) was approved in 2023. Binary SMBHs are prime sources of the low-frequency waves sought by pulsar timing arrays, including India’s InPTA. ✎ Mains Practice Question What is multi-messenger astronomy? Explain how long-term monitoring of objects such as binary supermassive black holes can advance our understanding of the universe, highlighting India’s contribution. 10 marks · 150 words 03 Why Nuclear Power Is Central to the Race for Permanent Moon Bases ImportantGS-III · S&T — Space Technology · GS-II International TreatiesPrelims + MainsThe Hindu · Analysis NASA plans to install a nuclear fission reactor near the Moon’s south pole by 2030, while Russia is developing a reactor for the China-led International Lunar Research Station (ILRS). Power for a semi-permanent base has become the first test of the US–China lunar race. ◈ Basics First — Why Not Solar? Lunar night — a location on the Moon gets about 14 Earth days of darkness at a time, and temperatures plunge far below freezing. South pole — attractive because permanently shadowed craters may hold water ice, but they receive no sunlight at all. Fission reactor — splits uranium nuclei to produce steady heat and electricity regardless of sunlight; NASA tested a small prototype (KRUSTY, 2018) under its Kilopower project. RTG (Radioisotope Thermoelectric Generator) — converts heat from the natural decay of plutonium-238; reliable but produces only hundreds of watts, suited to probes and rovers rather than bases. The Legal Framework Outer Space Treaty (1967) — bans nuclear weapons in orbit and on celestial bodies and any national appropriation of the Moon, but does not prohibit nuclear power. UN Principles Relevant to the Use of Nuclear Power Sources in Outer Space (1992) — non-binding safety guidelines. Moon Agreement (1979) — declares the Moon the common heritage of mankind; few space powers have ratified it (India signed but has not ratified). Artemis Accords (2020) — US-led principles; provide for temporary “safety zones” to avoid harmful interference. India signed in June 2023. Critics fear such zones could become de facto territorial claims. Significance and the India Angle Two blocs — the Artemis programme and the ILRS (China–Russia, 2021) are competing for the same resource-rich polar region; whoever establishes power infrastructure first gains a practical edge. Safety concerns — launch accidents, radiation shielding and disposal of spent fuel need international norms. India — Chandrayaan-3 landed near the south pole (August 2023); India aims to set up the Bharatiya Antariksh Station by 2035 and land an Indian on the Moon by 2040, making long-duration power technology strategically relevant. ✎ Mains Practice Question Plans for nuclear reactors on the Moon highlight the gaps in the international legal regime governing outer space. Discuss, with reference to the Outer Space Treaty and the Artemis Accords, and suggest a position India should take. 15 marks · 250 words Environment & EcologyGeneral Studies Paper III 04 Why Stubble Fires Keep Coming Back: Water Law, Procurement Incentives and the Measurement Problem Core TopicGS-III · Environment — Pollution; Agriculture — Cropping Patterns, MSPPrelims + MainsThe Hindu · Full Context Every October–November, burning of paddy straw in Punjab and Haryana worsens air quality across North India. The analysis argues that the practice persists because of a combination of groundwater law, assured procurement, free power and a narrow window between crops — and that official claims of a sharp decline rest on flawed measurement. ◈ Basics First — What Is Stubble Burning? Stubble — the lower stalks left in the field after harvest. Combine harvesters, in use since the late 1970s, leave about a foot of stubble. Scale — Punjab and Haryana together produce around 29 million tonnes of paddy straw a year. Harm — releases PM2.5, carbon monoxide, VOCs and carcinogens that form smog; burns away soil nitrogen, sulphur, phosphorus, potash, organic matter and moisture, raising fertiliser use for the next crop. Why it peaks in winter — calm winds and temperature inversion in the Indo-Gangetic plain trap pollutants near the ground. The Root Causes Punjab Preservation of Sub-Soil Water Act, 2009 — to save groundwater, it barred paddy nursery sowing before 10 May and transplanting before 10 June. This pushed harvest to late October, leaving only a 10–15 day window before wheat sowing. The groundwater crisis — a 2009 NASA GRACE satellite study found that Punjab, Haryana and Rajasthan lost about 109 cubic km of groundwater in 2002–2008. Long-duration varieties — high-yield PUSA-44 (150–160 days) further squeezed the window. Incentive structure — assured MSP procurement and free or near-free farm power lock farmers into the water-intensive rice–wheat cycle. Figure 3 — Procurement as a Share of Production, Average 2012–2024 0%50%100%37%87%74%30%70%63%PaddyWheatIndiaPunjabHaryanaNational averages include Punjab and Haryana; excluding them, the gap would be wider Assured procurement of more than four-fifths of Punjab’s paddy makes switching to other crops economically unattractive. Data as cited in the article. Solutions and Their Limits In-situ — crop residue management (CRM) machines (Happy Seeder, Super Seeder, rotavators), short-duration varieties such as PR-126, direct seeding of rice (DSR), and IARI’s PUSA bio-decomposer. But seeders need a costly 60-HP tractor; hiring costs around ₹10,000. Ex-situ — using straw for compressed biogas, bio-ethanol, biomass power and co-firing; collection costs ₹1,500–2,500 per acre. Haryana’s incentive model — ₹1,000/acre for CRM use, ₹4,000/acre for DSR, ₹7,000/acre for crop diversification, plus panchayat incentives; Punjab has relied mainly on in-situ machinery. Enforcement — CPCB flying squads were deployed in 2025; a Parliamentary committee recommended that penalising farmers be the last resort, with a minimum price for selling straw. ▤ The Measurement Problem Official claim — Punjab and Haryana together recorded a 90% reduction in fire incidents in 2025 compared with 2022. Method — the CREAMS protocol (IARI) counts active fires from NASA’s polar-orbiting MODIS and VIIRS sensors, which pass over India only around 10:30 am–1:30 pm. Evidence of evasion — an ISRO-led study using geostationary satellites found farmers shifting burning to evening hours; a multi-satellite estimate of burnt area showed a decline of only about 30%. Implication — combine polar and geostationary data and measure burnt area, not just fire counts. ◈ Institutions & Law to Know Commission for Air Quality Management in NCR and Adjoining Areas Act, 2021 — created the CAQM (replacing the EPCA); farmers are kept out of its penal provisions but liable to environmental compensation for stubble burning. Graded Response Action Plan (GRAP) — staged anti-pollution measures in Delhi-NCR linked to AQI levels. Crop Residue Management scheme (2018) — central subsidy for CRM machinery in Punjab, Haryana, UP and Delhi. Judicial signals — the NGT (2018) held that farmers who burn stubble could be excluded from MSP benefits, a view the Supreme Court upheld in 2023. Way Forward Short term — affordable access to CRM machines through custom hiring centres, assured straw purchase for CBG plants, promotion of short-duration varieties. Medium to long term — diversification away from paddy through price and procurement support for pulses, maize and oilseeds, and rational power pricing. Honest measurement — penal targets can create perverse incentives for farmers and officials to show rather than achieve reductions. ✎ Mains Practice Question “Stubble burning is less a farmer’s choice than the outcome of policy incentives.” Critically examine this statement and suggest a mix of technological, economic and institutional measures to end the practice. 15 marks · 250 words 05 Living Planet Report 2026: Monitored Wildlife Populations Down 73% Since 1970, but Recovery Is Possible Core TopicGS-III · Environment — Biodiversity Conservation, Reports & IndicesPrelims + MainsWWF · The Indian Express WWF’s biennial Living Planet Report 2026 finds that the average size of monitored vertebrate populations fell by 73% between 1970 and 2022. Freshwater species fared worst, and the food system is named the single largest driver of biodiversity loss — yet about half of the tracked populations are stable or increasing. ◈ Basics First — Reading the Living Planet Index Correctly Living Planet Index (LPI) — tracks the average rate of change in the relative abundance of monitored vertebrate populations (amphibians, birds, fish, mammals, reptiles). What 73% does not mean — it is not the loss of 73% of individual animals, nor of 73% of populations or species; it is the average decline in population size. Data base (2026) — 35,803 populations of 5,790 species. History — developed by WWF in 1998; managed with the Zoological Society of London (ZSL) since 2006; used as an indicator under the CBD and the Kunming–Montreal Global Biodiversity Framework. WWF — founded in 1961; headquartered at Gland, Switzerland (also home to the IUCN). Figure 4 — Average Decline in Monitored Wildlife Populations, 1970–2022 Global average−73%BY ECOSYSTEMFreshwater−85%Terrestrial−69%Marine−59%BY REGIONLatin America & Caribbean−95%Africa−80%Asia & the Pacific−49% Freshwater ecosystems — hit by dams, pollution, over-abstraction and invasive species — show the steepest decline. Data: WWF Living Planet Report 2026. Drivers and Signs of Recovery Main drivers — habitat loss and degradation, overexploitation, climate change, invasive species, pollution and disease. Food system — the leading cause of habitat destruction and overharvesting, and a major source of greenhouse gas emissions. Recoveries — green turtles, bluefin tuna, southern African elephants and tigers: global wild tiger numbers rose from about 3,200 (2010) to around 5,700 (2025). India’s share — India holds about three-quarters of the world’s wild tigers; the 2022 estimate was 3,682, reflecting Project Tiger (1973) and the NTCA. Positive tipping points — rapid growth of solar, wind and EVs shows systems can change fast; similar shifts are needed in food and finance. ◈ Static Background — The Convention on Biological Diversity CBD — opened for signature at the Rio Earth Summit (1992), alongside the UNFCCC; in force from 1993; India became a Party in 1994. Three objectives: conservation, sustainable use, and fair and equitable sharing of benefits. Cartagena Protocol on Biosafety — adopted 2000, in force 2003; regulates transboundary movement of living modified organisms. Nagoya Protocol on Access and Benefit-Sharing — adopted 2010, in force 2014. India’s law — the Biological Diversity Act, 2002 (amended 2023) and the National Biodiversity Authority; the CBD COP meets every two years. Kunming–Montreal GBF (2022) — 23 targets for 2030, including protecting 30% of land and sea (“30×30”). ✎ Mains Practice Question The Living Planet Report identifies the global food system as the largest driver of biodiversity loss. Discuss this link and examine how India can align its agricultural practices with the goals of the Kunming–Montreal Global Biodiversity Framework. 15 marks · 250 words Internal Security & Disaster ManagementGeneral Studies Paper III 06 SAREX-2026: Coast Guard Rehearses a Mass Maritime Rescue off Paradip, with Observers from 30 Countries ImportantGS-III · Security — Maritime Security; Disaster Management · GS-II Regional GroupingsPrelims + MainsPIB · Ministry of Defence The Indian Coast Guard (ICG) conducted the 12th National Maritime Search & Rescue Exercise (SAREX-2026) off Paradip, Odisha on 7–8 October 2026, simulating a mass rescue operation, and hosted the 24th National Maritime SAR (NMSAR) Board meeting at Bhubaneswar. 32 observers from 30 countries attended. ◈ Basics First — What Is Search and Rescue (SAR)? Search and rescue — locating people in distress and delivering them to a place of safety; at sea it covers ship sinkings, fires, man-overboard cases and aircraft ditchings. Search and Rescue Region (SRR) — the ocean area for which a country accepts SAR responsibility. India’s maritime SRR covers about 4.6 million sq km of the Indian Ocean. Mass Rescue Operation (MRO) — an incident where the number of people in distress exceeds the immediately available rescue capacity, demanding coordination of many agencies. Aeronautical–maritime link — air crashes at sea are handled jointly; procedures are harmonised in the IAMSAR Manual, issued jointly by the IMO and ICAO. ▤ Exercise at a Glance Scenario: a passenger aircraft with 228 people ditching at sea and colliding with a container vessel — concurrent aeronautical and maritime distress. Assets: 15 ICG ships, two Dornier aircraft, three Advanced Light Helicopters and a Chetak, IAF C-130J and Mi-17, two Navy ships, plus civil and State assets. International: 32 observers from 30 countries. NMSAR Board agenda: SAR preparedness, distress-alert management, faster mobilisation through technology integration and inter-agency coordination. Static Background — India’s Maritime SAR Architecture Indian Coast Guard — set up on an interim basis in February 1977 and given statutory form by the Coast Guard Act, 1978; an armed force of the Union under the Ministry of Defence. Coordinating authority — the ICG coordinates maritime SAR in the Indian SRR through Maritime Rescue Coordination Centres (MRCCs) at Mumbai, Chennai and Port Blair. NMSAR Board — the apex national body for maritime SAR policy, chaired by the Director General, ICG, bringing together ministries, the armed forces, ports and shipping agencies. Distress alerting — the satellite-based COSPAS-SARSAT system (India’s mission control centre is at ISTRAC, Bengaluru) and ISRO-developed distress alert transmitters for fishing boats. Legal obligations — SOLAS Convention (1974) and the International Convention on Maritime Search and Rescue (1979) under the IMO; aeronautical SAR under Annex 12 of the Chicago Convention (ICAO). Significance Preparedness — rising sea and air traffic, and the cyclone-prone east coast, make large-scale rescue capability essential. Maritime diplomacy — foreign observers support India’s role as a first responder in the Indian Ocean, in line with SAGAR (2015) and MAHASAGAR (2025). Interoperability — joint drills among the ICG, Navy, IAF, ports, airlines and State agencies test command, communication and handover procedures. Challenges — the vast SRR, safety of small fishing craft, and integration of alerts from multiple systems into a single picture. ✎ Mains Practice Question India is responsible for search and rescue across a vast area of the Indian Ocean. Discuss the institutional framework for maritime SAR in India and examine how it supports India’s aspiration to be a first responder in the region. 10 marks · 150 words Art, Culture & PersonalitiesGeneral Studies Paper I 07 Nobel Prize in Literature 2026: Canadian Poet-Classicist Anne Carson Honoured for Remaking Literary Forms ImportantGS-I · Art & Culture — Literature; Awards & Personalities in NewsPrelims + MainsThe Indian Express Anne Carson (76, Canada) — poet, classicist, essayist and translator — received the 2026 Nobel Prize in Literature “for her bold and inventive oeuvre that, in playful dialogue with the classical tradition, has created new forms for contemporary literature”. ◈ Basics First — The Nobel Prizes Origin — established by the will (1895) of Swedish chemist Alfred Nobel, inventor of dynamite; first awarded in 1901 in Physics, Chemistry, Medicine, Literature and Peace. Economics — the Sveriges Riksbank Prize in Economic Sciences, added in 1968, is not one of the original five. Awarding bodies — Literature: the Swedish Academy (est. 1786); Physics and Chemistry: Royal Swedish Academy of Sciences; Medicine: Nobel Assembly at the Karolinska Institutet; Peace: the Norwegian Nobel Committee in Oslo. Recent Literature laureates — Han Kang (South Korea, 2024) and László Krasznahorkai (Hungary, 2025). Figure 5 — The Laureate and Her Notable Works Image courtesy The Indian Express, October 2026; reproduced with credit for educational use. The Laureate and Her Work Background — born in Toronto (1950); studied Classics at the University of Toronto; her doctoral thesis (1981) was on the ancient Greek poet Sappho. Eros the Bittersweet (1986) — her first book, on desire as created by distance and longing, read through classical texts. Autobiography of Red (1998) — a novel in verse recasting the Greek myth of Geryon, the red-winged monster killed by Herakles, as a modern coming-of-age story. The Beauty of the Husband (2001) — made her the first woman to win the T.S. Eliot Prize. Nox (2010) — an accordion-fold book of grief combining photographs, letters and translation; later works include Float (2016) and Wrong Norma (2024). Translations — Sappho (If Not, Winter), Euripides and other Greek classics. Why She Stands Out Genre-blending — a poem becomes an essay, an essay a translation, a translation an autobiography; she rejects fixed literary categories. Classics as contemporary — uses ancient Greek myth and fragments to explore modern themes of desire, loss and grief. Restraint — writes about intense emotion with deliberate detachment rather than confessional warmth. ▤ India Connect — Prelims Pegs Rabindranath Tagore (1913) — the first non-European Literature laureate, for Gitanjali. Alice Munro (2013) — the previous Canadian Literature laureate. International Booker Prize 2025 — Banu Mushtaq’s Heart Lamp, translated by Deepa Bhasthi, the first Kannada work to win. ✎ Mains Practice Question Translation and re-interpretation of classical traditions can give old literatures a new life. Discuss with reference to India’s classical and regional literary heritage and its recent global recognition. 10 marks · 150 words Ethics, Integrity & AptitudeGeneral Studies Paper IV 08 Case Study: A District Collector Confronts Segregated Water Taps — Persuasion, Punishment or Both? ConciseGS-IV · Ethics — Attitude, Social Influence & Persuasion; Case StudiesMains-orientedThe Hindu · Parley As District Collector, you learn that in several villages, Dalit families are informally barred from a common water tap and their children sit separately at the anganwadi. Registering cases may provoke a backlash; ignoring it violates Article 17 and your oath. ◈ Ethics Toolkit Rule of law and constitutional morality — enforcement under the PCR Act and SC/ST (PoA) Act is a duty, not an option. Attitude change — attitudes have cognitive, affective and behavioural parts; law changes behaviour, while contact, persuasion and role models change beliefs and feelings. Persuasion tools — credible local leaders, school-level interventions, shared village functions, and public recognition of inclusive panchayats. Values — dignity, fraternity, empathy and courage; Ambedkar’s idea of constitutional morality versus social morality. Approach — immediate restoration of equal access and protection for complainants, combined with sustained community engagement. ✎ Mains Practice Question Identify the ethical issues in the above case. As the District Collector, outline your course of action, explaining how you would combine legal enforcement with persuasion to bring lasting change in social attitudes. 20 marks · 250 words
