Chaired by the Union Labour Minister, the Board will recommend, monitor and review welfare schemes for workers who fall outside traditional employer–employee relationships. ◈ Key Terms Explained — From Basics Social security: protection against life risks — old age, sickness, disability, maternity, unemployment, death — through pensions, insurance and benefits. Unorganised worker: a home-based, self-employed or wage worker in the unorganised sector, or a worker not covered by the main formal-sector social security laws. Gig worker: a person who performs work or participates in a work arrangement and earns outside a traditional employer–employee relationship — e.g. freelance or task-based work. Platform worker: a gig worker who uses an online platform to access customers or organisations and get paid — e.g. food delivery, ride-hailing, home services. All platform workers are gig workers, but not vice versa. Aggregator: a digital intermediary or marketplace that connects buyers or users of a service with providers — the platform company. Why the gap: India’s social security laws were built around a clear employer who pays contributions (as in EPF and ESI). Gig and platform work has no such employer, so these workers fell outside the net. ◈ Static Background — Constitution and Law DPSPs: Article 38 (social order and welfare), 39(e) (health of workers), 41 (public assistance in unemployment, old age, sickness), 42 (just and humane conditions of work, maternity relief), 43 (living wage). Seventh Schedule: “social security and social insurance” — Entry 23, and “welfare of labour” — Entry 24, both in the Concurrent List; hence both Centre and States legislate. Lineage: the Unorganised Workers’ Social Security Act, 2008 created a National Social Security Board for unorganised workers; it was subsumed by the Code on Social Security, 2020, which for the first time defined gig and platform workers in law. The four Labour Codes: the Code on Wages (2019), Industrial Relations Code (2020), Code on Social Security (2020) and Occupational Safety, Health and Working Conditions Code (2020) consolidated 29 central labour laws; they were brought into force in November 2025.

Chair: Union Minister for Labour & Employment. Members: Central and State Government representatives, aggregator companies, employers, civil society, workers’ unions and gig & platform associations. Meetings: at least three times a year. Functions: recommend schemes for different categories of workers; advise the Centre; monitor central welfare schemes; review State-level record keeping; review expenditure from the fund; other assigned tasks. Figure 2 — India’s gig workforce (lakh workers) 2020–21772029–30 (projected)235About a three-fold rise in a decadeProjected at about 6.7% of the non-farm workforce by 2029–30 Bars drawn to scale. Chart recreated by Legacy IAS from NITI Aayog, “India’s Booming Gig and Platform Economy” (2022). Related Initiatives e-Shram portal (2021): national database of unorganised workers, with over 30 crore registrations; gig and platform workers are being registered and issued ID cards. Health cover: the Union Budget 2025–26 announced Ayushman Bharat PM-JAY coverage for registered gig and platform workers. Pensions: PM Shram Yogi Maan-dhan (2019), a contributory pension scheme for unorganised workers. State laws: Rajasthan (2023) passed India’s first law on platform-based gig workers; Karnataka (2025) and others have followed with welfare boards and cesses on aggregators. Why It Matters Scale: about 90% of India’s workforce is informal; the gig economy is one of its fastest-growing segments, especially among urban youth. Formal voice: including aggregators, unions and gig associations on one Board creates a tripartite forum for a sector without collective bargaining. Fiscal model: aggregator contributions create a dedicated source of funding rather than relying only on the budget. The Critical View Advisory, not executive: the Board recommends and monitors; outcomes depend on schemes actually notified and funded. Employment status unresolved: gig workers are not treated as employees, so protections tied to employment (minimum wages, working hours, dismissal rules) may not apply. Abroad, the UK Supreme Court (Uber v Aslam, 2021) classed drivers as “workers”, and the EU Platform Work Directive (2024) introduced a presumption of employment. Algorithmic management: account “deactivation”, opaque pay algorithms and safety are concerns not addressed by social security alone. Federal overlap: parallel State laws and central schemes need coordination on registration, contributions and portability as workers move across States and platforms. Balanced view: India is among the first countries to legislate social security specifically for platform workers; the Board’s notification moves the framework from paper towards practice. ✎ Mains Practice Question The gig and platform economy creates jobs but challenges the traditional employer-based model of social security. Examine how the Code on Social Security, 2020 and the newly constituted National Social Security Board address this challenge, and what gaps remain. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III 02 Geospatial Capabilities as an Engine of Growth: Survey of India, the 2022 Policy and the Push for Industry Partnership Core TopicGS-III · S&T — IT, Space Applications; Economy — Infrastructure, StartupsGS-I · Geography — MappingPrelims + MainsPIB · Ministry of Science & Technology · 30 Oct 2026 At a Survey of India workshop on government–industry synergy, the Union Minister for Science & Technology described geospatial capability as a key determinant of India’s growth, calling for an approach of “enable, invest and adopt” and wider use of geospatial AI under the National Geospatial Policy, 2022. ◈ Key Terms Explained — From Basics Geospatial data: information tied to a location on Earth — coordinates, boundaries, elevation, roads, land use — collected by satellites, aircraft, drones and ground surveys. GIS (Geographic Information System): software that stores, layers and analyses location data on maps. GNSS and CORS: satellite navigation systems (GPS, NavIC) give positions; a network of Continuously Operating Reference Stations on the ground corrects them to centimetre-level accuracy. LiDAR: laser-based scanning that builds precise 3-D models of terrain and structures. DEM (Digital Elevation Model): a 3-D representation of the Earth’s surface, used in flood modelling, roads and irrigation design. Digital twin: a live virtual replica of a city or asset built from geospatial data. Geospatial AI: machine learning applied to imagery and maps — e.g. automatically detecting buildings, crops or encroachments. ◈ Static Background — Survey of India Founded 1767 — among the oldest scientific departments in the world; headquartered in Dehradun; functions under the Department of Science & Technology. Its head is the Surveyor General of India. Great Trigonometrical Survey (from 1802): began under William Lambton to measure the subcontinent precisely; Radhanath Sikdar computed the height of Peak XV (1852), later named after Surveyor General George Everest. Today: moving from labour-intensive ground surveys to satellite, drone and computer-based mapping, and building national positioning infrastructure (CORS). Figure 3 — Lineage of India’s mapping and geospatial policy 1767Survey of Indiafounded1802Great TrigonometricalSurvey begins2005National Map Policyrestrictive regime2021Guidelines liberalisedno prior approvals2022National GeospatialPolicy; GDPDCShift: from controlled, government-only maps to open data, privateparticipation and a negative list of sensitive attributes Diagram drawn by Legacy IAS from Department of Science & Technology information. ▤ The Policy Framework 2021 Guidelines: removed prior approval requirements for acquiring and producing geospatial data and maps; Indian entities can collect and use data freely except for a negative list of sensitive attributes; the most accurate data are reserved for Indian entities. National Geospatial Policy, 2022: aims to make India a world leader in the geospatial sector by 2035; DST is the nodal department; an apex Geospatial Data Promotion and Development Committee (GDPDC) guides implementation; envisages national frameworks for high-resolution maps, elevation data and an integrated data infrastructure. Related policies: Drone Rules, 2021; Indian Space Policy, 2023. Flagship users: SVAMITVA (2020) — drone mapping of rural inhabited areas for property cards; PM GatiShakti National Master Plan (2021) — multi-layer GIS platform for infrastructure planning; urban land-record mapping; disaster management. Why It Matters Governance: accurate maps underpin land records, taxation, infrastructure planning, disaster response and welfare targeting. Economy: geospatial services feed agriculture (crop insurance assessment), logistics, telecom, real estate, insurance and urban planning; startups and MSMEs can build on open data. Energy transition and climate: siting renewable plants, mapping resources and modelling floods and heat depend on geospatial data. Strategic autonomy: indigenous high-accuracy positioning (CORS, NavIC) reduces dependence on foreign systems. The Critical View Openness vs security: liberalisation must be balanced with protection of sensitive locations; the negative-list approach needs clear, regularly updated rules. Privacy: high-resolution imagery and location data can reveal personal information; alignment with the DPDP Act is needed. Capacity and standards: many departments lack GIS skills; data from different agencies often use incompatible formats and scales. Market maturity: demand from government still dominates; building commercial markets requires procurement reform and data-sharing norms. ✎ Mains Practice Question India has moved from a restrictive mapping regime to an open geospatial policy. Discuss the significance of geospatial technologies for governance and economic growth, and the challenges of balancing openness with security and privacy. 15 marks · 250 words

Editorials, Opinions & Explained3 Items Core TopicImportantConcise EditorialsGS II · GS III 01Social Security Boards — Centralisation & Coverage Gaps OpinionsGS II · GS III 02India–China — Managed Coexistence03Ashoke Sen, String Theory & Basic Research EditorialsThe paper’s own arguments, analysed 01 Suboptimal Outcomes? Centralised Social Security Boards and the Unfinished Agenda for Informal Workers Core TopicEditorialGS-II · Welfare of Vulnerable Sections; Federalism; Statutory BodiesGS-III · Employment, Informal SectorPrelims + MainsThe Hindu · Editorial (“Suboptimal outcomes”) Welcoming the constitution of the National Social Security Boards one year after the Code on Social Security came into force, the editorial argues that their centralised design — chaired by the Union Labour Minister and nominated by the Centre — may limit outcomes for a workforce that is overwhelmingly informal, in a subject that falls in the Concurrent List. ◈ Static Background — Social Security Concepts ILO definition: the protection a society provides to individuals and households to ensure access to health care and income security — in old age, unemployment, sickness, invalidity, work injury, maternity or loss of a breadwinner. ILO Convention No. 102 (1952): sets minimum standards across nine branches of social security; India has not ratified it. Constitution: Article 41 (public assistance) and Article 43 (living wage) among the DPSPs; “social security and social insurance” (Entry 23) and “welfare of labour” (Entry 24) are in the Concurrent List. NCEUS (2004–09): the National Commission for Enterprises in the Unorganised Sector, chaired by Arjun Sengupta, documented the scale of informality and recommended a universal social security floor for informal workers. Today’s framework: the Code on Social Security, 2020 (in force since November 2025) defines gig and platform workers and provides for National Social Security Boards (see today’s PIB Analysis). Figure 1 — Composition of the two Boards (number of members) Unorganised workers(40 members)7726 — governments, experts, othersGig & platform workers(22 members)5512 — othersWorkers’ representativesEmployers / aggregatorsBoth Boards are chaired by the Union Labour Minister; members are nominated by the Centre Bars drawn to scale (10 units per member). Chart recreated by Legacy IAS from figures cited in the editorial. The Editorial’s Argument Centralisation: the Union Government chairs both Boards and nominates all members; the editorial argues that Central Trade Unions and State Governments are not adequately represented. Federal principle: since labour is a Concurrent subject, Centre and States must work together; a report prepared for the Kerala government (Justice V. Gopala Gowda, 2026) flagged provisions it considered anti-federal and suggested amendments. Coverage claims vs reality: the Government cites social protection coverage rising from 19% (2015) to 64.3% (2025) — about 94 crore people — but informal workers, over 90% of the workforce, largely lack comprehensive protection in the ILO sense. Unfinished agenda: many NCEUS recommendations remain unaddressed; trade unions and States should be brought on board. Analysis and Other Views Government’s perspective: a national Board ensures uniform standards, portability for migrant workers and coordination with aggregators operating across States; States can also constitute their own Boards and schemes. Measuring coverage: headline coverage figures often count anyone receiving at least one benefit (e.g. food or cash transfers), which differs from comprehensive cover against all major risks — a distinction worth noting in answers. Design questions: tripartism (government–employer–worker) is a core ILO principle; the balance of nominated vs elected or union-chosen members affects legitimacy and trust. Balanced view: the Boards are a necessary institutional step; their effectiveness will depend on funding, notified schemes and genuine consultation. ✎ Mains Practice Question Social security in India has expanded in coverage but remains thin for informal workers. Critically examine the institutional design of the National Social Security Boards under the Code on Social Security, 2020, with reference to federalism and tripartism. 15 marks · 250 words OpinionsSigned op-eds, analysed with counter-views 02 Can India and China Coexist Peacefully? A Case for Reading China Right Core TopicOpinionGS-II · IR — India and its Neighbourhood (China), Border ManagementGS-III · Security — Border AreasPrelims + MainsThe Hindu · Op-Ed (former National Security Adviser) The author describes India–China relations as “managed coexistence” and argues that peaceful coexistence is possible: conflict would set back both countries, China’s military edge is often overstated, and India should avoid treating China as an existential threat — while better understanding Chinese intentions and preventing incidents like Galwan (2020). ◈ Static Background — The Boundary Question Line of Actual Control (LAC): about 3,488 km, in three sectors — Western (Ladakh; dispute over Aksai Chin), Middle (Himachal Pradesh, Uttarakhand) and Eastern (Sikkim, Arunachal Pradesh). McMahon Line: drawn at the Simla Convention (1914) between British India and Tibet; China does not accept it and claims much of Arunachal Pradesh. Panchsheel (1954): five principles of peaceful coexistence, in the India–China agreement on trade with Tibet. 1962 war, followed by decades of a frozen boundary; the 1988 prime-ministerial visit to Beijing created a Joint Working Group and separated the boundary question from overall ties.

The Author’s Argument Beyond Galwan: the 2020 clash, in which 20 Indian soldiers died, does not by itself explain the depth of mistrust; the roots lie in 1962 and in poorly delineated boundaries. Lost momentum: the 1988 opening was a watershed whose gains were later “frittered away”; recent initiatives risk becoming a zero-sum game, with Chinese strategists reading India’s role in the Quad as part of containment. No existential threat: conflict would derail China’s long-term goals; China’s military, though advancing, is “not yet world-class”, and India is a match in the high Himalayas. Existing commitments: the 2005 Agreement on Political Parameters and Guiding Principles commits both sides to not using or threatening force and to protecting settled populations in any boundary settlement. Prescription: better understanding of China’s intentions and internal frailties; clear instructions to border forces to avoid incidents; a relationship of “strategic stability”. Counter-Views and Balance Security concerns: many analysts point to China’s rapid border infrastructure build-up, the 2020 transgressions that upset agreed norms, the China–Pakistan partnership, and upstream projects on the Yarlung Tsangpo as reasons for caution. Economic asymmetry: India runs a very large trade deficit with China and depends on Chinese inputs for electronics, pharmaceuticals (APIs) and solar equipment. Strategic choice: India’s participation in the Quad reflects multi-alignment rather than alliance; India also engages China through BRICS and the SCO. Academic frame: the author’s view leans towards liberal-institutionalist reassurance; a realist reading stresses capabilities and power balance. A balanced answer combines deterrence with dialogue. ✎ Mains Practice Question India–China relations are often described as “managed coexistence”. Examine the factors that sustain mistrust between the two countries and evaluate the mechanisms available to maintain peace along the Line of Actual Control. 15 marks · 250 words 03 Making Room for Ideas Yet to Be Tested: Ashoke Sen, String Theory and the Value of Basic Research ImportantOpinionGS-III · S&T — Achievements of Indians; Science PolicyMains-orientedThe Indian Express · Op-Ed (theoretical physicist) Marking Ashoke Sen’s receipt of the Oskar Klein Medal — the first Indian to win it — a fellow physicist argues that theories can remain untested for decades yet prove profoundly useful, and that India’s institutions must protect the freedom to pursue such ideas. ◈ Concepts to Know Klein–Gordon equation (1926): the first wave equation consistent with special relativity, describing particles with zero spin. For decades no such fundamental particle was known — until the Higgs boson (spin 0) was discovered at CERN in 2012. Kaluza–Klein theory: gravity in a hypothetical five-dimensional spacetime reduces to both gravity and electromagnetism in our four dimensions — an early attempt at unification. String theory: treats fundamental objects as tiny strings rather than points; it offers a consistent framework for quantum gravity, requires extra dimensions (10 or 11 in different formulations), but has no direct experimental confirmation yet. Electric–magnetic (S-) duality: a symmetry exchanging the roles of electricity and magnetism; Sen’s 1994 work provided strong evidence for it within string theory. Black hole entropy: Sen’s methods helped explain the microscopic origin of black-hole entropy and information puzzles. Figure 3 — Theory first, confirmation later: two examples Klein–Gordon (1926)spin-0 wave equation~86 years as a “toy model”Higgs boson (2012)spin-0 particle foundKaluza–Klein (1920s)extra dimensionString theory + dualitiesSen’s work, 1990sExperimental test?still awaited Diagram drawn by Legacy IAS from the author’s argument. The Author’s Argument Patience pays: like the Klein–Gordon equation, string theory has generated rich theoretical insight even without direct experimental confirmation. Sen’s contributions: showing that consistency of strings in curved spacetime yields Einstein’s equations with corrections; evidence for duality that unified different string theories into one web; and work on black holes; over 300 papers. Institutional ecosystem: Sen worked at TIFR, HRI and ICTS — autonomous institutes of the Department of Atomic Energy — whose founder, Homi J. Bhabha, valued freedom of inquiry. Concern: some scepticism of string theory within India’s physics community may reflect limited appreciation of how frontier science works. Counter-Views and Balance The falsifiability debate: critics argue that a theory without testable predictions risks drifting from empirical science (the Popperian criterion of falsifiability); supporters reply that mathematical consistency and explanatory power are themselves scientific progress. Resource allocation: in a country with modest R&D spending (well under 1% of GDP), there is a debate on balancing curiosity-driven and mission-oriented research — the ANRF aims to fund both. Policy lesson: autonomy, long-term funding and tolerance of uncertain outcomes are common features of institutions that produce breakthrough research. ✎ Mains Practice Question “Basic research rarely yields immediate applications, yet it underpins long-term scientific capability.” Discuss with reference to India’s institutions for fundamental research and the debate over funding untested theories. 10 marks · 150 words

Unlike Assembly polls, MLC elections involve special electorates — MLAs, local-body members, graduates and teachers — and use preferential voting by ballot paper, not EVMs. ◈ Static Background — The Second Chamber in States Optional bicameralism: the Constitution mandates two Houses at the Centre but leaves the choice to States. Six States have Councils — Andhra Pradesh, Bihar, Karnataka, Maharashtra, Telangana and Uttar Pradesh. Jammu & Kashmir’s Council was abolished in 2019. Article 169 — creation or abolition: Parliament acts by ordinary law, on a resolution of the State Assembly passed by a special majority (majority of total membership and two-thirds of those present and voting). It is not treated as a constitutional amendment under Article 368. Article 171 — size: not fewer than 40 members and not more than one-third of the Assembly’s strength. Permanent House: members serve six years; one-third retire every two years. Minimum age: 30. Constituent Assembly debate: supporters saw a revising chamber representing diverse expertise; critics feared cost, delay and patronage. The compromise: optional Councils with limited powers — on money bills a Council can only delay for 14 days, and on ordinary bills it can delay but not block the Assembly. Figure 1 — Composition of a Legislative Council (Article 171) 1/3 — elected by MLAs(not from among themselves)1/3 — local bodiesmunicipalities, district boards etc.1/121/12~1/6GraduatesTeachersNominated byGovernorGraduates: resident in the constituency, graduated at least 3 years earlierTeachers: taught at least 3 of the last 6 years in an institution not below secondary schoolNominees: literature, science, art, co-operative movement, social service Bar widths drawn to proportion. Diagram drawn by Legacy IAS from Article 171 and the Representation of the People Act, 1950. How the Voting Works Single transferable vote (STV): voters rank candidates (1, 2, 3…); a candidate reaching the quota is elected, surplus votes pass to next preferences, and the lowest candidates are eliminated in turn. Quota formula: [votes ÷ (seats + 1)] + 1. Example: 200 MLAs, 4 seats → 200 ÷ 5 = 40; quota = 41. Ballot papers, not EVMs: ranking preferences requires paper ballots; the same applies to Rajya Sabha, Presidential and Vice-Presidential elections. Open vs secret ballot: in Rajya Sabha polls, MLAs must show their ballot to their party’s agent (open ballot, introduced in 2003); in MLC polls they do not. Fresh rolls: graduates’ and teachers’ electoral rolls are prepared afresh before each election, with 1 November as the qualifying date. Historical roots: functional representation traces to the Government of India Act, 1935; in the Constituent Assembly, the idea of representing the province’s “intelligentsia” led to graduate and teacher seats. ▤ Ballot Papers Elsewhere in India Local body elections are run by State Election Commissions (Articles 243K, 243ZA), which may choose EVMs or ballots; a 2023 study found most States still use ballots for gram panchayat polls. Student union elections use either method, depending on the institution. The Debate on Councils For: a revising chamber, space for expertise and functional constituencies, continuity as a permanent House. Against: limited powers, cost, potential use to accommodate those who lose direct elections; the graduates’ franchise is seen by some as elitist in a universal-suffrage democracy. Process concerns: several proposals by States to create or abolish Councils remain pending with Parliament, showing the dependence on central legislation. ✎ Mains Practice Question Discuss the rationale for Legislative Councils in Indian States and examine whether they fulfil the role envisaged for them by the Constitution’s framers. 15 marks · 250 words 02 The Theni Jailbreak: Overcrowding, Understaffing and the Case for Prison Reform ImportantGS-II · Governance — Criminal Justice, Prisons, Human RightsMains-orientedThe Hindu · In Focus On 26 October, 17 remand prisoners escaped from the Theni district jail in Tamil Nadu after feigning a medical emergency and overpowering a warden; all were caught within 42 hours with the help of drones. Only 6 of 33 sanctioned staff were on duty, and prisons are reported to hold 80–100% more inmates than capacity. ◈ Static Background — Prisons in India Constitution: “Prisons, reformatories, borstal institutions” are a State subject (Entry 4, State List). Law: the colonial Prisons Act, 1894 still governs many States; the Centre circulated the Model Prisons and Correctional Services Act, 2023 and the Model Prison Manual, 2016 for States to adopt. Key terms: a remand (undertrial) prisoner is held in custody by court order pending trial; a convict has been sentenced. Scale (NCRB Prison Statistics, 2022): national occupancy above 130%; about three-fourths of inmates are undertrials. Reform history: Mulla Committee (1983); Justice Krishna Iyer Committee (1987) on women prisoners; Supreme Court in Re: Inhuman Conditions in 1382 Prisons (2016) on overcrowding and reform. Undertrial relief: Section 479, BNSS allows release of undertrials who have served half (one-third for first-time offenders) of the maximum sentence. What the escape revealed: chronic staff shortages, faulty alarms and poor lighting, inmates who could not furnish bail sureties, and mixing of occasional and habitual offenders. Expert view: prisons often function as punishment centres rather than correctional institutions; psychological support and staff training are needed. Reform priorities: reduce undertrial numbers through faster trials and legal aid; fill vacancies; modernise security and surveillance; classify inmates; adopt the 2023 model law; invest in rehabilitation and mental health. ✎ Mains Practice Question Overcrowding and the high share of undertrial prisoners reflect deeper failures of the criminal justice system. Discuss, and suggest reforms to make Indian prisons correctional rather than merely custodial institutions. 15 marks · 250 words EconomyGeneral Studies Paper III 03 World Bank Finds “Remarkable Progress” in Reducing Poverty — but Flags Wage Gaps and Geographic Concentration Core TopicGS-III · Economy — Poverty, Inclusive Growth, EmploymentGS-II · Issues Relating to PovertyPrelims + MainsThe Hindu The World Bank’s Poverty and Equity Brief for India (October 2026) reports that extreme poverty fell from 27.1% to 2.6% between 2011 and 2023, and that about 496 million people moved above the lower-middle-income poverty line — among the fastest declines in the world. It also notes wide wage gaps, poverty concentrated in an eastern belt, and rising youth unemployment. ◈ Key Terms Explained — From Basics Poverty line: a minimum level of income or consumption needed for basic needs; the poverty headcount ratio is the share of people below it. Purchasing Power Parity (PPP): an exchange rate that equalises what money can buy across countries — so “$3 a day” means what $3 buys in the U.S., converted to local prices. International lines (2021 PPP): $3.00/day — extreme poverty; $4.20/day — the poverty line for lower-middle-income countries (LMICs) such as India. The World Bank updated these lines in 2025. Multidimensional Poverty Index (MPI): measures deprivation in health, education and living standards (e.g. nutrition, schooling, cooking fuel, sanitation, housing), developed by OPHI (Oxford) and UNDP; India’s NITI Aayog publishes a national MPI. Inequality measures: the Gini coefficient (0 = perfect equality, 1 = maximum inequality) and earnings ratios, such as the top-10% to bottom-10% median. Figure 2 — Share of India’s population below international poverty lines (%) 57.716.1$4.20/day (LMIC line)27.12.6$3.00/day (extreme)20112023 Bars drawn to scale. Chart recreated by Legacy IAS from the World Bank Poverty and Equity Brief as reported. ▤ Key Findings (as reported) Multidimensional poverty: fell from 53.8% (2005–06) to 16.4% (2019–21) on the OPHI measure; 15.5% in 2022–23 on the World Bank’s measure. Wage inequality: median earnings of the top 10% of workers were about 13 times those of the bottom 10% (2023). Geographic concentration: a contiguous belt from Uttar Pradesh to West Bengal holds about 57% of India’s poor. Jobs: employment rose by about 134 million between 2017 and 2023, nearly twice working-age population growth, driven largely by rural women entering paid work. Youth: youth unemployment rose from 14.6% to 15.9% between Q1 FY2026 and Q1 FY2027, especially among rural young women. Drivers cited: consumption growth, rising employment and expanded social transfers, including food subsidies. Lineage — How India Has Measured Poverty Alagh Task Force (1979): calorie-based poverty lines. Lakdawala (1993) → Tendulkar (2009): shifted to a consumption basket including health and education; poverty at about 21.9% in 2011–12. Rangarajan (2014): higher lines (29.5% in 2011–12); not formally adopted. Since then: no official consumption-based poverty line; estimates rely on the Household Consumption Expenditure Survey (2022–23, 2023–24) and NITI Aayog’s national MPI. Critical Assessment Methodology matters: changes in survey design between rounds and the choice of poverty line affect comparisons; experts urge caution in reading exact magnitudes. Vulnerability: many people have moved just above the line and remain vulnerable to shocks such as illness, crop failure or job loss. Inequality and regions: concentration of poverty in the eastern belt calls for region-specific strategies in jobs, infrastructure and human capital. Quality of jobs: employment growth driven by self-employment and unpaid-to-paid transitions may not mean secure, well-paid work; rising youth unemployment is a warning sign. ✎ Mains Practice Question India has achieved one of the fastest reductions in extreme poverty, yet inequality and regional concentration of poverty persist. Examine the drivers of poverty decline and the challenges that remain. 15 marks · 250 words Science & TechnologyGeneral Studies Paper III 04 GSLV-F18 Places NVS-03 in Orbit, Paving the Way to Restore NavIC ImportantGS-III · S&T — Space Technology, Indigenisation; SecurityPrelims + MainsThe Hindu; The New Indian Express ISRO’s GSLV-F18 lifted off from Sriharikota late on 30 October and placed the 2,250-kg NVS-03 satellite into a geosynchronous transfer orbit. Once raised to its final slot, it will take the number of working NavIC satellites to four — the minimum needed for positioning. Figure 3 — GSLV-F18 on the second launch pad, Sriharikota The 50-metre, three-stage GSLV has a lift-off mass of about 420 tonnes; this was its 20th flight. Photo reproduced with credit for educational use. ◈ Key Terms Explained — From Basics GSLV: Geosynchronous Satellite Launch Vehicle — a three-stage rocket whose upper stage is an indigenous cryogenic stage (liquid hydrogen and liquid oxygen), used for heavier satellites. Geosynchronous Transfer Orbit (GTO): an elliptical orbit with a low perigee (closest point) and high apogee (farthest point); the satellite then fires its own engine to climb to its final orbit. NVS-03’s GTO: about 170 km × 37,000 km, inclined 20.75°. Geostationary vs geosynchronous: both take one day per orbit at about 36,000 km; a geostationary satellite sits over the equator and appears fixed, while an inclined geosynchronous one traces a figure-of-eight over a region. PNT: positioning, navigation and timing services. Atomic clock: the heart of a navigation satellite; NVS-03 carries an indigenous rubidium atomic clock along with procured clocks. ▤ NVS-03 at a Glance Mission life: 12 years; final slot at 32.5° East after orbit-raising. Signals: L1 (compatible with consumer devices) in addition to L5 and S bands. Coverage: India and about 1,500 km beyond its boundaries. Context: the last working atomic clock on IRNSS-1F stopped in March 2026; NVS-02 (January 2025) failed to reach its orbit because of a valve problem, since corrected. ISRO’s 2026 launches: PSLV-C62 (January, failed), GSLV-F17 with EOS-05 (September, successful), and now GSLV-F18 — the shortest gap yet between two GSLV launches. Significance: restores an indigenous PNT service vital for defence, maritime safety, fishermen’s alerts, railways, aviation and precise timing (“One Nation, One Time”). The test ahead: successful orbit-raising, steady clock performance and wider integration of NavIC in phones and devices will determine whether the system regains user trust. ✎ Mains Practice Question The repeated disruption of NavIC highlights the importance of reliability and indigenous components in strategic space systems. Discuss with reference to the NVS series of satellites. 10 marks · 150 words Geography, Environment & HeritageGeneral Studies Papers I & III 05 Lake Sediments Reconstruct 4,600 Years of Monsoon and Farming History in the Central Ganga Plain ImportantGS-I · Geography — Monsoon, Climate History; Ancient HistoryGS-III · Climate Change, AgriculturePrelims + MainsDD India / DST Scientists at the Birbal Sahni Institute of Palaeosciences (BSIP), Lucknow used sediments from Karela Lake, an oxbow lake near the Hulas Khera archaeological site in Lucknow district, to reconstruct 4,600 years of changes in the Indian Summer Monsoon, vegetation and early agriculture. Figure 4 — Study design and key climate phases A 155-cm sediment core records ~4,600 calibrated years before present (cal yr BP). Graphical summary of the BSIP study; reproduced with credit for educational use. ◈ Key Terms Explained — From Basics Palaeoclimate proxies: natural records that preserve past climate — lake sediments, pollen, cave deposits (speleothems), tree rings, ice cores. Oxbow lake: a crescent-shaped lake formed when a meandering river cuts off a loop — common in the Ganga plain. AMS radiocarbon dating: measures carbon-14 atoms directly with an accelerator mass spectrometer, giving precise ages from tiny samples. C3 vs C4 plants: C3 plants (most trees, wheat, rice) prefer cooler, wetter conditions; C4 plants (many grasses, maize, millets) cope better with heat and dryness. Carbon isotopes in sediments reveal which dominated. Holocene: the current geological epoch, from about 11,700 years ago; its latest stage, the Meghalayan Age, begins with the 4.2 ka mega-drought, defined using a stalagmite from Mawmluh Cave, Meghalaya. ▤ The Four Phases Identified ~4,600–4,300 years ago: strong monsoon; expansion of moist deciduous forest. ~4,200 years ago: the 4.2 ka arid event — weak monsoon (also linked to the decline of the Indus Valley Civilisation). ~3,100 years ago: stronger monsoon; evidence of agriculture, including manure-based practices. Roman Warm Period (~2,800–700 years ago in the record): lake-level changes and human adaptation; later the Little Ice Age (~600 years ago onwards) brought flooding and moisture from westerlies. Why it matters: long records provide a baseline for climate models, show how societies adapted to monsoon swings, and support planning for water and food security in one of the world’s most densely populated regions. Conservation angle: small oxbow lakes are valuable natural archives — and fragile wetlands that need protection. Prelims caution: Hulas Khera (Lucknow district) is distinct from Hulas (Saharanpur district), a Late Harappan site. ✎ Mains Practice Question How do palaeoclimate records help us understand the relationship between monsoon variability and the rise and decline of human settlements in the Indian subcontinent? 10 marks · 150 words 06 Mud Volcanoes, Andaman Subduction Volcanoes and Sirpur Added to India’s UNESCO Tentative List ImportantGS-I · Art & Culture; Geography — Volcanoes, Plate TectonicsPrelims-orientedHindustan Times Three Indian sites — the Karst–Mud Volcano Complex of Baratang, the Andaman Subduction Volcanoes (Barren and Narcondam islands) and the Sirpur Cultural and Archaeological Landscape (Chhattisgarh) — have been added to UNESCO’s World Heritage Tentative List, taking India’s tentative entries to 81. ◈ Static Background — How World Heritage Status Works World Heritage Convention (1972): adopted by UNESCO; India ratified it in 1977. Sites are inscribed by the intergovernmental World Heritage Committee. Tentative List: an inventory of sites a country intends to nominate; a site must be on it (generally for at least a year) before a nomination. Inclusion is not World Heritage status. Criteria: sites must show Outstanding Universal Value under at least one of ten criteria (six cultural, four natural), plus integrity and authenticity. Advisory bodies: ICOMOS evaluates cultural sites; IUCN evaluates natural sites. India’s count: India has over 40 inscribed World Heritage Sites, the latest including the Maratha Military Landscapes (2025). The Three Sites Baratang (Middle Andaman): mud volcanoes, which emit mud, water and gases (mainly methane) rather than molten rock, alongside limestone caves formed from uplifted marine sediments. Andaman Subduction Volcanoes: Barren Island — South Asia’s only confirmed active volcano — and Narcondam, a dormant volcanic island and the only home of the Narcondam hornbill. Both lie on the volcanic arc formed as the Indian Plate subducts beneath the Burma microplate. Sirpur (Mahasamund, Chhattisgarh): on the Mahanadi; historically Shripura, capital of Dakshina Kosala under the Panduvamshi dynasty. Known for the brick Lakshmana Temple (7th century) and Buddhist viharas, reflecting coexisting Hindu, Buddhist and Jain traditions. Significance: two geo-heritage entries widen India’s natural-heritage portfolio beyond forests and wildlife; Sirpur highlights a lesser-known early-medieval urban and religious centre. Challenges: nomination dossiers need strong management plans, legal protection, and buffer-zone controls — especially on ecologically fragile islands with tourism pressure. ✎ Mains Practice Question Geological heritage is as important as cultural heritage for a nation’s identity and science.
