Physical targets were long the headline measure; the backgrounder instead compiles before-and-after journey times stated by the Government for selected bridges, tunnels, expressways and trains. Bharatmala Pariyojana (2017) — umbrella programme for economic corridors, inter-corridors and border/coastal roads; successor to the National Highways Development Project (1998). PM Gati Shakti National Master Plan (October 2021) — GIS-based integrated planning across seven engines: roads, railways, airports, ports, mass transport, waterways and logistics infrastructure. National Logistics Policy (September 2022) — aims to bring logistics cost to global benchmarks; an NCAER (2023) estimate placed India’s logistics cost at 7.8–8.9% of GDP (2021-22), well below the oft-quoted 13–14%. India ranked 38th of 139 in the World Bank’s Logistics Performance Index 2023. ▤ The Numbers at a Glance Railway timetable 2026: 549 trains speeded up — 20 by 60 min or more, 48 by 31–59 min, 105 by 16–30 min, 376 by 5–15 min. Mumbai–Ahmedabad High-Speed Rail: 508 km, 12 stations, operational speed 320 kmph, journey of about 1 h 58 min; first service targeted for August 2027 (government target). Seven new HSR corridors announced in the Union Budget 2026-27: nearly 4,000 km, estimated investment ₹16 lakh crore (announced, not yet built). Delhi–Mumbai Expressway: projected cut from about 33 h to ~12 h (under development; government projection).

Values are the Government’s stated estimates. Bridges — removing river and sea barriers Bhupen Hazarika (Dhola–Sadiya) Setu (2017) — about 9.15 km over the Lohit; Rupai (Assam) to Meka/Roing (Arunachal Pradesh) cut from 6 h to 1 h. Bogibeel Bridge (2018) — India’s longest rail-cum-road bridge (about 4.94 km) over the Brahmaputra, linking Dhemaji and Dibrugarh; a day-long trip now takes 1–2 h. Kosi Rail Mahasetu (2020) — restored the Nirmali–Saraigarh link severed after the 1934 Bihar–Nepal earthquake; distance cut from about 300 km to 22 km, time from 8 h to 30 min. Atal Setu / Mumbai Trans Harbour Link (2024) — India’s longest sea bridge (about 21.8 km); Mumbai–Navi Mumbai in about 20 min. Sisseri River Bridge (2019) — 200 m link between Dibang Valley and Siang; Pasighat–Roing shortened by about 5 h. Tunnels — all-weather access in difficult terrain Atal Tunnel (2020) — 9.02 km under the Pir Panjal, bypassing Rohtang Pass; Manali–Sarchu shorter by 46 km, giving all-weather access to Lahaul-Spiti. Built by the Border Roads Organisation. Dr. Syama Prasad Mookerjee (Chenani–Nashri) Tunnel (2017) — about 9 km on NH-44; Jammu–Srinagar distance cut by about 30 km. Banihal–Qazigund Tunnel (2022) — 8.45 km twin-tube, replacing reliance on the older Jawahar Tunnel (1956); road distance cut by 16 km. Sela Tunnel (2024) — at about 13,000 ft on the strategic Tezpur–Tawang axis; matters for both civilian access and defence logistics along the LAC. Expressways and rail Access-controlled expressways — Delhi–Meerut (82 km), Bengaluru–Mysuru (118 km), Delhi–Dehradun (213 km, 2026), Mumbai–Nagpur Samruddhi Mahamarg (701 km), Ahmedabad–Dholera (109 km, 2026) and Delhi–Amritsar–Katra (Phase-I, 2026). Vande Bharat — first service on 15 February 2019 (New Delhi–Varanasi); the Katra–Srinagar service (2025) runs on the USBRL line, which includes the Chenab Bridge, the world’s highest railway arch bridge. Vande Bharat Sleeper (2026) — first on Howrah–Guwahati; about 3 h faster than the Saraighat Express, 16 AC coaches, ~823 passengers. MAHSR — based on Japan’s Shinkansen technology with JICA soft-loan financing; includes India’s first undersea rail tunnel, about 7 km beneath Thane Creek. Why it matters Time is an economic input — shorter, more predictable journeys lower inventory and freight costs and widen labour markets around cities. Regional integration — the North-East and Himalayan projects shift remote districts from seasonal or ferry-dependent access to all-weather connectivity. Strategic depth — tunnels and bridges near the borders (Sela, Atal, Bogibeel) double as defence infrastructure. The critical view Partial metric — hours saved say nothing about tolls, financing costs, induced traffic or who actually benefits; independent ex-post evaluations of such claims are scarce. Road safety — faster roads have not lowered fatalities in step; India recorded over 1.7 lakh road deaths in 2023 (MoRTH), and high-speed corridors have drawn scrutiny over crash rates. Himalayan fragility — the Silkyara tunnel collapse (November 2023), which trapped 41 workers for 17 days, highlighted geological and slope-stability risks of rapid construction in young mountains. Timelines — several flagship projects, including MAHSR (originally aimed at the early 2020s), have slipped due to land acquisition and clearances. Spatial equity — capital-heavy corridors can concentrate gains; rural and last-mile roads (PMGSY, 2000) and urban public transport remain decisive for most travellers. ✎ Mains Practice Question “Travel time saved” is increasingly used as the headline measure of infrastructure performance in India. Critically examine the adequacy of this metric in capturing the economic, social and ecological outcomes of transport infrastructure. 15 marks · 250 words 02 India Chem 2026: Positioning Chemicals and Petrochemicals as a Growth Engine GS-III · Economy — Industrial Policy, Manufacturing, R&DPrelims + MainsPIB · Ministry of Chemicals & Fertilizers (Dept. of Chemicals & Petrochemicals) The launch of the 14th India Chem was used to set out the Centre’s ambition of a USD 1 trillion chemicals industry by 2040, built on dedicated chemical parks, higher R&D and alignment with mineral, semiconductor and manufacturing missions. ▤ Event & Policy at a Glance Event: India Chem 2026, the biennial flagship event of the sector — 14th edition, Mumbai, 22–24 October 2026. Organisers: Department of Chemicals and Petrochemicals (DCPC), Ministry of Chemicals & Fertilizers, with FICCI. Theme: “Advantage Bharat: An Emerging Global Hub”. Format: international exhibition and conference; conclaves on agrochemicals, petrochemicals, speciality chemicals, infrastructure, environment and process plant & machinery; country forums with the US, EU, Russia and Japan. Key scheme: BHAVYA Rasayan — dedicated chemical parks with plug-and-play infrastructure; guidelines released, State Governments to submit proposals. Stated targets: USD 1 trillion industry and a global hub for battery, speciality and semiconductor chemicals by 2040 (government vision). ◈ Background & Context Chemicals feed nearly every manufacturing chain — fertilisers, pharmaceuticals, textiles, plastics and electronics. A NITI Aayog report (2025) placed India as the world’s sixth-largest chemicals producer but with only about 3.5% of global chemical value chains and a chemicals trade deficit of about USD 31 billion (2023). FDI: up to 100% under the automatic route is permitted in most chemicals, except certain hazardous ones. Regulatory anchor: the Bhopal gas tragedy (1984) led to the Environment (Protection) Act, 1986, the Hazardous Chemical Rules, 1989 and the Public Liability Insurance Act, 1991. Lineage — from PCPIRs to plug-and-play parks PCPIR Policy (2007) — Petroleum, Chemicals and Petrochemicals Investment Regions at Dahej (Gujarat), Paradip (Odisha) and Visakhapatnam–Kakinada (Andhra Pradesh); a proposed Cuddalore–Nagapattinam region did not proceed. Progress was uneven and slower than planned. Plastic Parks scheme (DCPC) — an earlier cluster model for downstream plastics processing. BHAVYA Rasayan — continues the cluster logic but emphasises ready common infrastructure to cut production costs; implementation runs through State proposals. Figure 2 — How the Government proposes to align missions with the chemicals sector National Critical Mineral MissionRare Earth CorridorIndia Semiconductor Mission 2.0National Manufacturing MissionFDI reformsChemicals & Petrochemicals+ BHAVYA Rasayan parks+ RDI Scheme (priority status sought)+ DPIIT import substitutionGlobal hub by 2040 for:Battery chemicalsSpeciality chemicalsSemiconductor chemicalsUSD 1 trillion industryby 2040 (government vision) The approach links input security (critical minerals, rare earths) and demand (semiconductors, manufacturing) to high-value chemical segments. Why it matters Import dependence — reliance on imported intermediates and key starting materials exposes pharmaceuticals and agrochemicals to supply shocks. Energy transition — battery chemicals (electrolytes, cathode precursors) and semiconductor-grade gases and solvents are inputs for EVs and chip fabs. R&D push — DCPC is seeking priority-sector status under the Research Development and Innovation (RDI) Scheme (outlay about ₹1 lakh crore) and is working with DPIIT on import substitution. The critical view Ambition vs. base — the 2040 figure is a projection; it implies a several-fold expansion from the current base and depends on sustained private capex. Low R&D intensity — Indian firms spend far less on R&D than global peers; speciality and semiconductor chemicals need deep process know-how that parks alone cannot supply. Cluster pollution — chemical hubs such as Vapi and Ankleshwar have figured among critically polluted areas on CPCB’s CEPI; the LG Polymers styrene leak (Visakhapatnam, 2020) showed persistent process-safety gaps. Feedstock and federal execution — petrochemicals depend on imported crude and naphtha, and park delivery depends on State land and clearances. ✎ Mains Practice Question India aspires to build a USD 1 trillion chemicals industry by 2040. Examine the structural constraints facing the sector and assess whether cluster-based approaches such as dedicated chemical parks can address them. 15 marks · 250 words Environment & EcologyGeneral Studies Paper III 03 India–Japan Joint Crediting Mechanism Moves to Implementation with Operational Manual GS-III · Environment — Climate Change, Carbon MarketsGS-II · IR — India–JapanPrelims + MainsPIB · Ministry of Environment, Forest and Climate Change The Operational Manual launched on 30 September 2026 completes the rule-making for India’s bilateral carbon-crediting arrangement with Japan under Article 6.2 of the Paris Agreement, opening it to actual project submissions. ◈ Background & Context International carbon crediting began under the Kyoto Protocol (1997; in force 2005), whose Clean Development Mechanism (CDM) let developed countries earn credits from projects in developing ones. India was among the largest CDM host countries. Paris Agreement, Article 6 — 6.2: bilateral “cooperative approaches” trading ITMOs; 6.4: a UN-supervised mechanism (the Paris Agreement Crediting Mechanism, CDM’s successor); 6.8: non-market approaches. Article 6 rules were adopted at COP26 (Glasgow, 2021), with remaining operational details settled at COP29 (Baku, 2024). Japan launched the JCM in 2013 (first partner: Mongolia) and has since signed it with around 30 countries. ▤ Mechanism at a Glance Legal basis: Article 6.2, Paris Agreement — bilateral cooperative approach. Parties: Government of India and Government of Japan. Nodal Ministry (India): MoEFCC; India’s Article 6 authority is the National Designated Authority for the Implementation of the Paris Agreement (NDAIAPA), constituted in 2022. Instruments: Memorandum of Cooperation (7 August 2025) → Rules of Implementation (8 June 2026) → Operational Manual (30 September 2026). Scope of the Manual: the full project cycle, from a Project Idea Note to the issuance and authorization of JCM credits. Stated objectives: deploy advanced low-carbon technologies, mobilise climate finance, enable technology cooperation and support high-integrity reductions and removals (as stated by the Government). Figure 3 — From agreement to credits: the India–Japan JCM A. Institutional sequence7 Aug 2025Memorandum of Cooperation8 Jun 2026Rules of Implementation30 Sep 2026Operational Manual launchedB. Project cycle (end points per the Manual; middle stages indicative of JCM practice)Project IdeaNote (PIN)Project DesignDocumentValidation bythird partyRegistration(Joint Cttee)Monitoringof reductionsVerificationby third partyIssuance &AuthorizationAuthorized credits transferred abroad = ITMOs under Article 6.2 → India applies a correspondingadjustment, so the same tonne is not counted towards both countries’ NDCs The Manual marks the shift from institutional preparation to implementation; credits authorized for transfer require a corresponding adjustment in India’s emissions accounting. How the mechanism works Japanese technology and finance are deployed in Indian projects; emission reductions are monitored, verified and issued as credits under rules agreed by both sides. Credits authorized for transfer become ITMOs that Japan can count towards its NDC — currently a 46% cut by FY2030 and 60% by FY2035, against FY2013 levels. India then makes a corresponding adjustment — adding the transferred tonnes back to its own ledger — to prevent double counting. Lineage — India’s carbon-market architecture CDM (Kyoto era) → Article 6 mechanisms (Paris era), with stricter accounting through corresponding adjustments. Perform, Achieve and Trade (PAT, 2012) under the National Mission for Enhanced Energy Efficiency → Energy Conservation (Amendment) Act, 2022 → Carbon Credit Trading Scheme (CCTS), 2023 for the domestic market. In 2023, India notified a list of activities eligible for Article 6.2 trading, focused on advanced technologies such as green hydrogen, offshore wind, storage-backed renewables and CCUS. Why it matters Finance and technology — channels capital towards technologies that are not yet commercially viable in India, supporting the updated NDC (2022): 45% cut in emissions intensity of GDP by 2030 over 2005 and net zero by 2070. Strategic partnership — adds a climate pillar to the Special Strategic and Global Partnership with Japan, alongside MAHSR and other JICA-funded projects. Market credibility — a codified project cycle signals to investors that Indian credits will meet Article 6 integrity standards. The critical view Mitigation space — every tonne transferred cannot count towards India’s own NDC; selling cheap abatement early could leave costlier cuts for later. India’s restricted activity list partly addresses this. Integrity lessons from CDM — over-crediting and weak additionality tests undermined CDM credibility; robust baselines and MRV are essential. Tied technology — the JCM has been criticised in other partner countries for favouring Japanese equipment suppliers, raising questions about genuine technology transfer. Interface with CCTS — clear rules are needed so the same reduction is not claimed in the domestic and international markets. ◈ Institutions & Terms to Know ITMO — Internationally Transferred Mitigation Outcome, the unit traded under Article 6.2. Corresponding adjustment — accounting entry by the host country to avoid double counting. NDAIAPA — India’s inter-ministerial authority for Article 6, chaired by the Secretary, MoEFCC. Project Idea Note (PIN) — the first submission in the JCM project cycle. ✎ Mains Practice Question Bilateral carbon-crediting arrangements under Article 6.2 of the Paris Agreement promise climate finance but raise concerns about environmental integrity and national mitigation space. Discuss with reference to the India–Japan Joint Crediting Mechanism. 15 marks · 250 words

Editorials, Opinions & Explained3 Items Core TopicImportantConcise EditorialsThe paper’s own view 01Great Indian Bustard & ‘Island’ Conservation OpinionsSigned op-eds 02Youth Bulge & the Global Jobs Crisis03Disability, Accessibility & AI EditorialsThe newspaper’s own arguments 01 Bird Islands: Why India’s Conservation Must Move from Species to Landscapes Core TopicEditorialGS-III · Environment — Biodiversity Conservation, Endangered SpeciesPrelims + MainsThe Hindu · Editorial The release of two captive-bred Great Indian Bustards in Desert National Park, Jaisalmer, is a real success — but the editorial argues that India’s wider conservation policy relies too much on flagship species and protected “islands”, and too little on the landscapes in which wildlife and people actually live. ◈ Basics First Species approach — conservation focused on saving one animal (a tiger, a cheetah, a bustard), usually through protected areas, captive breeding or relocation. Landscape approach — conservation that protects the whole ecosystem, including corridors, farmland, grasslands and villages, so that animals can move and survive outside fenced areas. Conservation breeding — raising a threatened species in captivity and then releasing it into the wild to rebuild numbers. It is an ex-situ method (outside the natural habitat); protecting habitat is in-situ. ▤ Great Indian Bustard (Godawan) — Species Profile Scientific name: Ardeotis nigriceps; one of the heaviest flying birds in the world; State bird of Rajasthan. Status: Critically Endangered (IUCN Red List); Schedule I, Wildlife (Protection) Act, 1972; Appendix I of both CITES and CMS (listed at CMS COP-13, Gandhinagar, 2020). Habitat: dry, open grasslands and semi-arid scrub; the main population is in Jaisalmer–Barmer (Rajasthan), with small numbers in Gujarat (Kutch), Maharashtra, Karnataka and Andhra Pradesh. Slow breeder: usually lays a single egg per breeding attempt, so populations recover very slowly. India’s four bustards: Great Indian Bustard, Lesser Florican, Bengal Florican and the migratory MacQueen’s (Houbara) Bustard. Figure 1 — Great Indian Bustard numbers: a half-century decline ~1,2601969~6002000140–1752010s (Rajasthan)~120Present (as cited)Approximate estimates; survey coverage differs across years Figures as cited in the editorial. The species lost roughly nine-tenths of its numbers in about five decades. The conservation breeding programme — where it stands The breeding effort is run jointly by the MoEFCC, the Rajasthan Forest Department and the Wildlife Institute of India (WII), with breeding centres at Sam and Ramdevra in Jaisalmer. Eggs collected from the wild were used to build a founder flock. 97 birds in the programme 57 captive-bred 29 chicks this year (24 last year) 9 more awaiting release Why the bird declined — the main threats Hunting — including by royalty; shooting reportedly continued into the late 1970s. Loss of grasslands — official land classifications long treated grasslands as “wastelands”; the spread of irrigation (notably after the Indira Gandhi Canal) converted them into farms using pesticides. Power lines — the bird is heavy, has poor frontal vision and flies at the height of overhead transmission lines, so collisions became the leading cause of death in its last stronghold. ◈ Static Anchor — History & the Supreme Court National bird debate: ornithologist Salim Ali proposed the bustard as national bird to secure its protection; the Indian Board for Wildlife chose the peacock, declared national bird in 1963. M.K. Ranjitsinh v. Union of India: in April 2021, the Supreme Court ordered overhead lines in the bird’s priority habitat to be laid underground where feasible, and bird diverters elsewhere. After renewable-energy developers argued this would raise costs, the Court revisited the order in March 2024, set up an expert committee, and recognised a right against the adverse effects of climate change under Articles 14 and 21. Undergrounding now applies only to the bird’s critical habitat. The editorial’s central argument — “conservation islands” The editorial says India tends to save a few celebrated species inside walled or fenced reserves, while thousands of less famous species decline unnoticed. It gives the following examples: Translocations — a tigress moved from Valmiki (Bihar) to Buxa (West Bengal); African cheetahs kept in enclosures at Kuno. Asiatic lions — confined to the Saurashtra region of Gujarat and now spilling into villages, causing human–wildlife conflict. Delhi Ridge — planted with peepal and banyan, trees that ecologists say do not belong to this dry, Aravalli-type ecology. Wider bird decline — the editorial cites about 1,256 bird species (≈11.5% of the world’s total) as threatened, and steep falls in skylarks (~80%) and Indian rollers (~30%) over 12 years. Analysis — the other side Flagships are not useless. Protecting a charismatic species can also protect its habitat (the umbrella-species effect), and public attention brings funding. Captive breeding buys time. For a bird with ~120 individuals, waiting for landscape-level change could mean extinction first. The real test is whether released birds survive outside enclosures — which depends on the same power lines and grasslands the editorial highlights. Way forward — landscapes as the unit of conservation Recognise grasslands as ecosystems, not “wasteland”, in land records and renewable-energy siting policy. Build on community traditions such as orans (sacred groves of Rajasthan) and on Community and Conservation Reserves under the 1972 Act. Use OECMs (Other Effective area-based Conservation Measures), which count conservation outside formal reserves towards the “30 by 30” target of the Kunming–Montreal Global Biodiversity Framework (2022). Plan wildlife corridors and conflict mitigation together, as India’s experience with elephants shows is necessary. ✎ Mains Practice Question India’s wildlife conservation is often criticised for favouring flagship species and enclosed reserves over landscapes. Critically examine this view with reference to the Great Indian Bustard, and suggest how a landscape approach could be adopted. 15 marks · 250 words OpinionsSigned op-ed articles 02 The Looming Crisis of World Unemployment: When the Demographic Dividend Turns into a Burden Core TopicOpinionGS-III · Economy — Employment, Growth & DevelopmentGS-I · Population & Associated IssuesPrelims + MainsThe Hindu · Opinion A recent World Bank warning — that 1.2 billion young people in the Global South will reach working age over the next decade, against only about 400 million projected jobs — is the starting point for an argument that the classic route from a young population to prosperity is breaking down. ◈ Basics First Demographic dividend — the growth opportunity that arises when the share of the working-age population (15–64) rises relative to dependants (children and the elderly). It usually follows a fall in fertility. Why it helps — more earners and fewer dependants mean higher savings, more investment and faster growth. This powered the “East Asian Miracle” (a 1993 World Bank study of high-growth East Asian economies). Youth bulge — an unusually large share of young people in a population. The catch — the dividend is only an opportunity. It pays off only if young people find productive jobs; otherwise it becomes a demographic burden. Figure 2 — The size of the gap, and India’s structural problem A. Global South, next decade (World Bank warning)Youth reaching working age1.2 billionJobs projected~400 millionShortfall~800 millionB. India — agriculture’s shareShare of workforce~46%Share of GDP (FY24)~16% Panel A: figures as cited in the article. Panel B: workforce share from PLFS 2023-24; GDP share as cited in the article. The article’s argument in brief The global economy faces a shortfall of about 800 million jobs in the coming decade. The traditional ladder — agriculture → light manufacturing → services — is weakening because automation and robotics make factories need fewer workers. Developing countries are therefore seeing premature deindustrialisation: manufacturing jobs shrink before the country becomes rich. Unemployed youth can fuel social unrest, polarisation, extremism and forced migration towards the Global North. Figure 3 — Why the old development ladder no longer works as well Classic path (East Asia, late 20th century)Agriculturelow productivityLight manufacturingabsorbs semi-skilled labourServices & high incomeskills, savings, capitalToday’s path for many developing economiesAgriculturesurplus labour staysManufacturing rungweakened by automationInformal servicesunder-/unemploymentWorkers skip industry and move straight into low-productivity services — “premature deindustrialisation” The term “premature deindustrialisation” is associated with economist Dani Rodrik (2015). ◈ Static Anchor — Concepts to Know Lewis Dual-Sector Model (1954) — growth happens as surplus labour moves from low-productivity agriculture to higher-productivity industry. Premature deindustrialisation breaks this transfer. Structural transformation — the shift of output and workers from agriculture to industry and services. Jobless growth — GDP rises but employment does not rise proportionately. Disguised unemployment — more people working on a farm than needed; removing some would not reduce output. India’s position World’s most populous country since 2023 (UN estimates), with a median age below 30. Fertility has fallen below replacement — TFR 2.0 (NFHS-5, 2019–21) against the replacement level of 2.1 — so the demographic window will not stay open indefinitely. Agriculture still employs about 46% of workers (PLFS 2023-24) while producing roughly 16% of GDP — a sign of low productivity and disguised unemployment. Female Labour Force Participation has risen to about 41.7% (PLFS 2023-24), but much of the increase is in self-employment and unpaid family work. The ILO–IHD India Employment Report 2024 found that youth make up about 83% of India’s unemployed. Solutions suggested — sector by sector Enabling reforms — lower the cost of capital, simplify regulation, stabilise taxation and protect property rights so that MSMEs, the main job creators, can grow. Infrastructure — creates jobs during construction and lowers business costs afterwards; the article notes India does better here than on regulation. Agriculture — move to high-value agribusiness: cold chains, food processing and climate-resilient farming, reducing distress migration. Care economy — nurses, community health workers and elder-care staff; these are non-outsourceable jobs that especially open doors for women. Tourism and culture — labour-intensive, hard to automate and with a broad multiplier effect on transport, hospitality and crafts. Reimagined manufacturing — green manufacturing (solar components, electric two-wheelers) and decentralised production, combined with skilling. Indian policy responses (for answer-writing) Skill India Mission (2015) and PMKVY; vocational education under NEP 2020. Production Linked Incentive (PLI) schemes (2020) to expand manufacturing. Employment Linked Incentive, approved in 2025 as the Pradhan Mantri Viksit Bharat Rozgar Yojana, which rewards employers for adding formal jobs. PM Internship Scheme (2024) to give youth work experience in large companies. Analysis — a balanced view Strength: the article correctly treats jobs, not GDP alone, as the core test of development, and links employment to social stability. Limitation: global job projections are uncertain; new sectors (the gig and platform economy, digital services) may create jobs that forecasts miss — though often without social security. Quality matters as much as quantity: India’s problem is often underemployment and informality, not only open unemployment. Skills mismatch: many graduates are not job-ready, so education reform is as important as job creation. ✎ Mains Practice Question “The demographic dividend is an opportunity, not a guarantee.” Discuss the factors that threaten to turn India’s youth bulge into a demographic burden, and suggest sector-specific strategies for absorbing labour. 15 marks · 250 words 03 Disabled Citizens and the Future of AI: Building Inclusion into the System, Not After It ImportantOpinionGS-II · Social Justice — Vulnerable Sections, Persons with DisabilitiesGS-III · S&T — Artificial IntelligencePrelims + MainsThe Hindu · Opinion AI tools are giving many persons with disabilities new independence, but the article warns that India is deploying AI in public services, recruitment and healthcare without testing it for disability bias — repeating the old mistake of building systems first and adding accessibility later. ◈ Basics First Accessibility — designing buildings, websites, services and devices so that everyone, including persons with disabilities, can use them without special help. Universal design — designing for the widest range of users from the start, rather than adding fixes later. Social model of disability — disability arises mainly from barriers in society (inaccessible buildings, websites, attitudes), not only from a person’s impairment. Algorithmic bias — when an AI system gives worse or unfair results for some groups, usually because its training data under-represents them. ▤ Legal Framework at a Glance UN Convention on the Rights of Persons with Disabilities (UNCRPD), 2006 — India ratified in 2007. Rights of Persons with Disabilities (RPwD) Act, 2016 — replaced the 1995 Act; recognises 21 types of disability; Section 40 (accessibility standards) and Section 42 (access to information and communication technology). Chief Commissioner for Persons with Disabilities — statutory authority under the RPwD Act that monitors compliance; the article notes it penalised 155 establishments, including ministries, for inaccessible websites and apps. Rajive Raturi v. Union of India (November 2024) — the Supreme Court held accessibility to be part of the right to life and dignity (Article 21), found the existing rules merely advisory, and directed the Centre to frame mandatory standards within three months. Amar Jain v. Union of India (April 2025) — the Court held digital access (e.g. accessible e-KYC) to be part of Article 21. Accessible India Campaign (Sugamya Bharat Abhiyan), 2015 — national campaign for accessible buildings, transport and ICT. The problem — how AI can exclude Biased language models — in the AccessEval benchmark, 21 language models tested across nine kinds of disability made more errors, used a more negative tone and stereotyped more when disability was mentioned. Biased image models — the widely used CLIP model was 15 percentage points less accurate on photos taken by blind and low-vision users; objects like a white cane or Braille display appeared up to 17 times less often in training data. Patronising responses — chatbots often respond to a blind person’s career question with sympathy (“I’m sorry you’re blind”) instead of advice. Weak existing compliance — digital accessibility has been mandatory since 2019 under the 2016 Act, yet most services still fall short; AI is being built on this weak base. Figure 4 — AI helps, but rarely on its own Users surveyed2,462Completed a task earlier closed to them1,313…through AI alone543…needed a staff member’s help770770 = 1,313 − 543 (derived). Survey by the author’s organisation, as cited in the article. Fewer than half of the successful users managed with AI alone — showing the need for a human fallback. The infrastructure angle — data centres and the grid The Centre is seeking about $200 billion in AI investment over two years; India’s data-centre capacity is projected to more than quadruple to 6.5 GW or more by 2030 (as cited). States compete with power subsidies and duty waivers; Maharashtra relaxed the renewable-energy requirement for data centres from 100% to 51%. Extra electricity demand can strain the grid at summer peaks, and server heat can worsen urban heat. Persons dependent on powered wheelchairs or oxygen concentrators are among the first harmed by power cuts. Analysis — a balanced view AI as an enabler: screen readers, image descriptions and form-filling help are real gains; the article does not argue against AI. Inclusion by design: the principle “Nothing about us without us” — disabled persons should help shape AI from data collection to deployment. Data and consent: the Digital Personal Data Protection Act, 2023 requires verifiable consent of a lawful guardian for some persons with disabilities, so inclusive datasets must be gathered carefully and ethically. Implementation gap: courts have spoken clearly, but enforcement capacity and penalties remain weak. Way forward Mandatory bias testing for disability in every AI system the government deploys. Representative training data, collected with consent, that includes the lives and tools of disabled persons. Human-in-the-loop support so that no citizen is left stranded when AI fails. Conditions on data-centre incentives — renewable sourcing and assessment of grid and heat impact.

Parliamentary privileges are special rights and immunities enjoyed by each House, its committees and its members. They exist so that legislators can speak and act without fear or obstruction while performing their duties. Article 105 — privileges of Parliament; Article 194 — privileges of State legislatures. Clause (1) and (2) — freedom of speech in the House; no court case for anything said or any vote given there. Clause (3) — other privileges “as defined by law”; until then, those existing before the 44th Amendment (1978). Originally this clause referred to the British House of Commons. Not codified — Parliament has never passed a law defining privileges, so their scope is uncertain. Codification has been recommended by bodies such as the NCRWC (2002). Breach of privilege / contempt of the House — an act that obstructs the House or its members. The House can reprimand, admonish or even imprison the offender. How the case began In 2003, The Hindu reported heated exchanges in the Tamil Nadu Assembly. The Speaker referred the reports to the Privileges Committee, calling them untrue and a breach of privilege. The newspaper then published an editorial arguing that privilege protects the House’s functioning, not the reputation of the government. A Tamil translation by Murasoli was also referred. The Assembly held five journalists and the Murasoli editor guilty, sentencing them to 15 days’ imprisonment. The Supreme Court stayed the arrest warrants and referred the questions to a larger Bench.

Two conflicting Constitution Bench views — Searchlight (1959) and Keshav Singh (1964) — are why the matter now needs a larger Bench. ◈ Static Anchor — The Two Conflicting Precedents Pandit M.S.M. Sharma v. Sri Krishna Sinha (Searchlight case, 1959, 4:1) — held that Article 194(3) includes the power to prohibit publication of House proceedings. Because Article 19(1)(a) is a general provision and Article 194(3) a special one, free speech must yield. Keshav Singh (Special Reference No. 1 of 1964, under Article 143) — the UP Assembly jailed a citizen for a pamphlet and ordered the arrest of the two High Court judges who granted him bail. The Court held that courts can examine the legality of detention ordered by a House, and that judges and lawyers cannot be punished for doing their duty. Keshav Singh also clarified that Searchlight did not create a universal rule that all Part III rights (Articles 12–35) yield to privilege. ▤ Other Cases & Provisions to Know Blitz case (1954) — editor detained on the UP Speaker’s warrant was released because he was not produced before a magistrate within 24 hours (Article 22(2)). Raja Ram Pal v. Speaker, Lok Sabha (2007) — upheld the expulsion of MPs in the cash-for-query case, but held that the exercise of privilege is subject to judicial review. Sita Soren v. Union of India (2024, seven judges) — bribery by legislators is not protected; overruled P.V. Narasimha Rao (1998). Articles 122 and 212 — courts cannot question the validity of proceedings on grounds of irregularity of procedure. Article 361A (44th Amendment) — protects publication of substantially true reports of legislative proceedings, unless made with malice. Committee of Privileges — 15 members in the Lok Sabha (nominated by the Speaker); 10 members in the Rajya Sabha (nominated by the Chairman). What the petitioners argue Free press — honest reporting is the bedrock of parliamentary democracy; journalists cannot work under fear of jail. Liberty and due process — depriving a person of liberty by a mere resolution of the House must meet the standards of Articles 14 and 21: fairness, natural justice and non-arbitrariness. Purpose of privilege — it protects the institution, not a Chief Minister, a government or the ruling party’s reputation. Analysis — the balance the Court must strike Case for privilege: legislatures need protection from obstruction and deliberate misreporting to function independently; this flows from the separation of powers. Case for limits: an uncodified power that lets a House act as accuser, judge and jailer sits uneasily with constitutional supremacy and the rule of law. Likely middle path: privileges may survive, but their use against outsiders could be held subject to Part III and judicial review — consistent with the direction of Keshav Singh, Raja Ram Pal and Sita Soren. Codification — a clear statute would reduce misuse, though legislators have long resisted it because it could make privileges justiciable. ✎ Mains Practice Question “Legislative privileges exist to protect the functioning of the House, not to shield it from scrutiny.” In the light of judicial precedents, critically examine whether privileges under Articles 105 and 194 should be subject to the fundamental rights in Part III. Should privileges be codified? 15 marks · 250 words 02 Mining Amendment Curbs State Taxing Powers: Why Mineral-Rich States Are Divided GS-II · Polity — Federalism, Centre–State Relations, Distribution of Legislative PowersGS-III · Economy — Mobilisation of ResourcesPrelims + MainsThe Hindu · Text & Context The Mines and Minerals (Development and Regulation) Amendment Act, 2026 extends the Centre’s control to mineral-bearing lands and bars States from levying fresh taxes on mineral rights, reopening a debate on the fiscal autonomy of mineral-rich States barely two years after a landmark Supreme Court ruling. ◈ Basics First Seventh Schedule — divides law-making powers into the Union List, State List and Concurrent List (Article 246). Mines are a shared subject — States regulate mining under Entry 23 (State List), but only to the extent Parliament has not taken control under Entry 54 (Union List). Royalty vs tax — royalty is the payment a mining lessee makes to the owner of the mineral for extracting it; a tax is a compulsory levy imposed by the State under its sovereign power. Fiscal federalism — how revenue-raising powers and spending duties are shared between levels of government. ▤ What the 2026 Amendment Does Wider central control — regulatory power now covers mineral-bearing lands, not only mines and mineral development. Bar on new State taxes — States cannot impose fresh taxes on mineral rights or mineral-bearing land, except under conditions set by the Union. Cancels past dues — mineral taxes levied by States but not fully collected before the Act came into force are invalidated. Centre’s rationale — multiple, uneven State levies raise the cost of domestic minerals, pushing industry towards imports. Figure 2 — The constitutional entries at the heart of the dispute Union List — Entry 54Regulation of mines & mineralsto the extent Parliament declaresState List — Entry 23Regulate mines & minerals,subject to Entry 54State List — Entry 50Tax mineral rights, subject toParliament’s limitsState List — Entry 49Tax lands & buildings(incl. mineral-bearing land)limitsmay limit2024 SC: cannot curtail2026 amendment uses the Entry 54 route to bar fresh State taxes on mineral rights and mineral-bearing land The amendment uses the Union’s regulatory entry to limit the States’ taxing entries — the point on which States are expected to go to court. ◈ Static Anchor — The 2024 Supreme Court Ruling Mineral Area Development Authority v. Steel Authority of India (July 2024) — a nine-judge Bench (8:1) held that royalty is not a tax, overruling India Cement (1989). States may tax mineral rights under Entry 50, subject to limits Parliament imposes in the public interest. Parliament cannot use Entry 54 to curtail the States’ power to tax mineral-bearing land under Entry 49. In August 2024, the Court allowed States to recover past dues from 1 April 2005, payable in instalments over 12 years from April 2026, without interest or penalty. Lineage of the law: MMDR Act, 1957 → 2015 amendment (auction regime, District Mineral Foundations, National Mineral Exploration Trust) → 2023 amendment (critical minerals, exploration licences) → 2026 amendment. The fiscal stakes — why responses differ Figure 3 — Dependence on mineral revenue, and each State’s response State challenging / objectingNo challenge so farJharkhand85%Odisha80%Karnataka48%Madhya Pradesh41%Rajasthan39%Telangana11%Chhattisgarh6%Mineral-related receipts as % of each State’s non-tax revenue (as cited) Dependence alone does not predict resistance: Odisha (80%) has not challenged the law, while Telangana (11%) intends to. Kerala and Himachal Pradesh also plan to challenge it. Challengers — Karnataka, Telangana, Himachal Pradesh and Kerala plan to move the Supreme Court. Kerala argues the definition of mineral-bearing land could extend central control over its coastal and forest areas. Jharkhand warns that losing uncollected past dues could hurt social-security schemes. No challenge — Odisha (whose government rejected demands for a special Assembly session), Madhya Pradesh, Rajasthan and Chhattisgarh. The pattern — mineral dependence determines the stake, but political alignment with the Union government appears to shape whether the stake turns into a federal dispute. Analysis — the federalism question Asymmetric fiscal federalism — the Union holds the more buoyant taxes, while States carry roughly three-fifths of general government spending; States also need central consent to borrow (Article 293). Constitutional tension — the amendment appears to contradict the 2024 ruling, especially on mineral-bearing land, and may be tested as an attempt to override a judgment without curing its basis. The Centre’s case — a single, predictable tax regime supports domestic mining, critical minerals and import substitution. Legal routes — States can sue the Union under Article 131 (original jurisdiction) or file writ petitions under Article 32. Wider pattern — similar Centre–State friction over GST compensation, Finance Commission terms of reference, NEP 2020 and All-India Services rules. Way forward Use the Inter-State Council (Article 263) or a dedicated consultative forum before changing State revenue powers. Offer compensation or revenue-sharing to highly dependent States, on the lines of the GST compensation model. Harmonise levies through agreed rate bands rather than an outright bar, balancing investor certainty with State autonomy. ✎ Mains Practice Question The MMDR (Amendment) Act, 2026 has reopened the debate on the fiscal autonomy of mineral-rich States. Examine the constitutional and fiscal issues involved, in the light of the Supreme Court’s 2024 ruling on taxation of mineral rights. 15 marks · 250 words 03 Viksit Bharat Shiksha Adhishthan Bill, 2025: One Regulator for Higher Education — Reform or Recentralisation? GS-II · Governance — Issues relating to Education, Statutory & Regulatory BodiesPrelims + MainsLok Sabha · Joint Parliamentary Committee review The VBSA Bill, 2025, now before a Joint Parliamentary Committee, proposes to replace three separate regulators with a single higher-education regulator. It has revived a long-standing debate: does Indian higher education suffer from too much regulation and too little autonomy? ◈ Basics First Higher Educational Institutions (HEIs) — universities, colleges and stand-alone institutions offering education after Class 12. Regulation — rules on who may open an institution, what it must teach and minimum standards. Accreditation — an independent check of quality. Funding — grants to institutions. Over-regulation — when compliance and paperwork crowd out teaching and research. Institutes of National Importance (INIs) — institutions such as the IITs, IIMs, AIIMS and NITs, declared by an Act of Parliament, with high autonomy. Constitutional position — education moved from the State List to the Concurrent List (Entry 25) by the 42nd Amendment (1976); Entry 66 of the Union List lets Parliament coordinate and set standards in higher education. ▤ Bill at a Glance Legislative status: introduced in the Lok Sabha on 15 December 2025; referred to a 31-member JPC. Replaces: the UGC (UGC Act, 1956), AICTE (1987) and NCTE (1993). Composition: a Chairperson and not more than 12 members. Three councils: Regulatory (entry, governance, graded autonomy), Accreditation (outcome-based, technology-driven) and Standards (learning outcomes, curricula, credit transfer). Funding separated: no grant-disbursal power; funding stays with the Ministry of Education. Excluded: medical and legal education (and architecture), which remain under their own councils. Penalties: up to ₹2 crore for fraudulent institutions and unauthorised degree-granting bodies. Other features: online, paperless approvals; graded autonomy; credits stored in a national credit bank for seven years with multiple entry and exit; six-month internships; campuses of top-500 foreign universities; and 30% of government funding linked to outcomes.

Radhakrishnan — recommended a central grants body, leading to the UGC. Kothari Commission (1964–66) — strongly backed university autonomy and public spending of 6% of GDP on education. National Knowledge Commission (2006–09) and Yash Pal Committee (2009) — both proposed a single overarching regulator; the NCHER Bill, 2011 lapsed. Draft HECI Bill, 2018 — proposed replacing the UGC; not enacted. NEP 2020 — proposed the Higher Education Commission of India (HECI) with four verticals: NHERC (regulation), NAC (accreditation), HEGC (funding) and GEC (standards). K. Radhakrishnan Committee (2024) on accreditation reform — recommended binary accreditation, maturity-based levels and a “One Nation One Data” platform. The over-regulation problem Compliance over pedagogy — faculty spend substantial time on documentation and evidence uploads for self-assessment reports, an “evidence blizzard”. Mechanical rules — the UGC Regulations, 2018 pair a 40-hour working week with five hours of daily presence, measuring academic work by the clock. Risk aversion — fear of penalties for technical lapses discourages experimentation; conventional practice becomes the safest choice. The autonomy evidence — IISc, IITs, IIMs, IISERs perform best partly because they operate outside the standard regulatory system. Concerns about the Bill Centralisation — one apex body may concentrate power and invite political interference without strong independence safeguards. Federalism — States fund most public universities, yet may have limited voice. The Gambhirdan Gadhvi (2022) ruling, which held UGC norms binding on State universities, and disputes over Vice-Chancellor appointments show the existing friction. Scale — one body would oversee about 1,168 universities and 45,473 colleges (AISHE 2021-22). Unclear performance criteria — graded autonomy and outcome-linked funding depend on metrics the Bill does not clearly define; institutions serving poorer or remote regions could lose out. INI autonomy — bringing IITs and IIMs under the umbrella could dilute the freedom behind their success. Digital divide — digital-only compliance may disadvantage rural and resource-poor institutions. Commercialisation — foreign campuses and relaxed faculty norms may favour revenue-driven education where public universities remain underfunded. Way forward “Light but tight” regulation, as in NEP 2020 — firm on fraud and commercialisation, hands-off on curriculum, pedagogy and recruitment. Statutory protection for INIs and for academic freedom. One Nation One Data to end duplicate inspections and repeated data demands. Outcome-based accreditation (learning, employability, research impact) instead of input metrics, aligned with frameworks such as the Washington Accord (India a full signatory since 2014). Cooperative federalism — formal State representation, an independent appellate mechanism, and clarity on State university funding. Context-sensitive funding metrics and higher public investment, since regulation alone cannot revive underfunded universities. ✎ Mains Practice Question Indian higher education is said to be “over-regulated and under-governed”. In this context, examine whether the proposed Viksit Bharat Shiksha Adhishthan can balance accountability with institutional autonomy and cooperative federalism. 15 marks · 250 words International RelationsGeneral Studies Paper II 04 India–Switzerland Ties: Mobility Pact, Defence and Nuclear Cooperation on TEPA’s First Anniversary GS-II · IR — Bilateral Relations, Agreements involving IndiaPrelims + MainsThe Hindu · PIB (MEA) During the State visit of the Swiss President, timed to the first anniversary of the India–EFTA Trade and Economic Partnership Agreement (TEPA), the two countries signed five agreements and identified new cooperation in defence production and nuclear energy. Figure 5 — Switzerland: a landlocked Alpine state at the heart of Europe Neighbours: France, Germany, Austria, Liechtenstein and Italy; capital (federal city) Bern; financial hub Zurich. Image courtesy BBC News; reproduced with credit for educational use. ◈ Basics First — Switzerland & EFTA Political system — a federal state of 26 cantons; executive power lies with a seven-member Federal Council, whose presidency rotates every year. Not in the EU, but part of the Schengen Area; known for permanent neutrality. Geneva hosts the WTO, WHO, ILO and the UN Human Rights Council. Four national languages — German, French, Italian and Romansh. EFTA (founded 1960) — Switzerland, Norway, Iceland and Liechtenstein. India–Switzerland Treaty of Friendship — signed in 1948. ▤ Outcomes of the Visit MoU on Migration and Mobility Partnership — multiple-entry visas up to 5 years (stays of up to 6 months per visit) and renewable one-year student permits, based on equal treatment; also aims to curb irregular migration and trafficking. Young Professionals Exchange — 300 persons a year each way, which “may” rise to 500. LoI between DST and the Swiss National Science Foundation on research cooperation. Cooperation in transport, mobility and infrastructure; India invited Swiss firms to invest in design, manufacturing and capacity building. New opportunities identified in military exchanges, defence production and nuclear energy. Static Anchor — TEPA Signed on 10 March 2024; in force from 1 October 2025. First Indian FTA with a binding investment commitment — EFTA aims to bring USD 100 billion of FDI over 15 years and create one million direct jobs in India. India’s first trade agreement with a group of developed European economies. Significance and unfinished business Mobility — adds Switzerland to India’s growing network of Migration and Mobility Partnership Agreements (France, UK, Germany, Italy, Austria and others), easing movement of students and skilled workers. Investment protection — Switzerland wants a new investment protection agreement. India terminated its earlier bilateral investment treaty after adopting the Model BIT (2016), which Swiss investors see as a gap. Intellectual property — Switzerland seeks stronger IP protection, especially in pharmaceuticals, a sensitive area for India’s generic drug industry. Nuclear and defence — Switzerland is a member of the Nuclear Suppliers Group, relevant to India’s membership bid; but Swiss neutrality and strict arms-export laws may limit defence cooperation. Financial transparency — automatic exchange of financial account information with India since 2018 has eased the old “Swiss bank” irritant. ✎ Mains Practice Question One year into the India–EFTA TEPA, examine how India–Switzerland relations are moving beyond trade into mobility, technology and strategic cooperation. What challenges remain? 10 marks · 150 words Science & TechnologyGeneral Studies Paper III 05 Nobel Prize in Physiology or Medicine 2026: Controlling Brain Cells with Light GS-III · S&T — Developments & Applications, Biotechnology, NeurosciencePrelims + MainsThe Hindu · The Indian Express Karl Deisseroth, Peter Hegemann and Georg Nagel have won the 2026 Nobel Prize in Physiology or Medicine “for their discoveries concerning light-gated ion channels and optogenetics” — a technique that lets scientists switch specific nerve cells on or off using light. Figure 6 — The 2026 laureates Deisseroth (Stanford University / HHMI, USA), Hegemann (Humboldt University of Berlin) and Nagel (University of Würzburg), Germany. Image courtesy The Indian Express, 6 October 2026; reproduced with credit for educational use. ◈ Basics First — How Neurons Work Neurons are nerve cells that communicate through electrical signals (action potentials) and chemical messengers (neurotransmitters). A neuron “fires” when ion channels in its membrane open and positively charged ions such as sodium rush in. The old problem — electrodes stimulate all nearby cells, so scientists could see correlations between brain activity and behaviour but could not prove which neurons cause which behaviour. Optogenetics = optics (light) + genetics: make chosen neurons light-sensitive, then control them with light at millisecond precision. The discovery — step by step The idea — Francis Crick suggested that controlling individual neurons with light would be ideal for studying the brain. Hegemann found that the green alga Chlamydomonas responds to light within about half a millisecond — about 20 times faster than the human eye (~10 ms) — suggesting a single protein both senses light and acts. Using the alga’s genome (mapped by Japanese researchers) and frog egg cells, Nagel and Hegemann identified channelrhodopsin-2 (ChR2), a light-gated ion channel, and showed it could make other cells light-sensitive. Deisseroth placed ChR2 into mammalian neurons in the mid-2000s and used light to control them — first in a dish, then in living rodents. Figure 7 — How optogenetics works 1. GeneOpsin gene (ChR2)from the alga2. DeliveryGene inserted intochosen neurons3. ExpressionNeuron makeslight-gated channels4. LightLight opens thechannel; ions flow5. EffectNeuron fires oris silencedActivate: channelrhodopsin + blue lightcation channel opens → depolarisation → firingSilence: halorhodopsin + yellow lightchloride pumped in → neuron inhibited Different light-sensitive proteins (opsins), activated by different colours of light, can switch neurons on or off. Why it matters — applications Mapping brain circuits behind pain, thirst, hunger, reward, attention, social behaviour, fear and memory; in mice, reactivating “memory” neurons triggered fear responses. Disease research — schizophrenia, depression, Alzheimer’s and Parkinson’s. Vision restoration — clinical trials in retinitis pigmentosa, a disease that destroys the retina’s rods and cones; a patient using light-emitting goggles could perceive and grasp objects. Hearing — possible light-based cochlear implants, which could be more precise than today’s electrical stimulation of the auditory nerve. Beyond the brain — e.g. pacing the heart with light to study how heart rate affects brain states. ▤ Static Anchor — The Nobel Prize Instituted by the will of Alfred Nobel (1895); first awarded in 1901. A prize can be shared by at most three laureates. The Medicine prize is decided by the Nobel Assembly at the Karolinska Institutet, Stockholm. 2025 laureates: Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi, for discoveries on peripheral immune tolerance (regulatory T cells). Indian link: Har Gobind Khorana shared the 1968 Medicine prize for interpreting the genetic code; Ronald Ross (born in Almora) won in 1902 for work on malaria transmission. Limitations and ethical questions Requires genetic modification, usually through viral vectors, and often implanted optical fibres because light penetrates tissue poorly. Use in humans is still early-stage; safety, long-term expression and consent in brain interventions need careful regulation. The ability to manipulate emotion and memory raises neuro-ethical concerns about misuse. Figure 8 — The laureates at a glance Image courtesy The Hindu, 6 October 2026; reproduced with credit for educational use. ✎ Mains Practice Question What is optogenetics? Explain how it has changed neuroscience research and discuss its potential therapeutic applications along with the ethical concerns it raises. 10 marks · 150 words 06 Bacterial Enzyme Makes DNA Without a Template: Testing the Limits of Biology’s Central Dogma GS-III · S&T — Biotechnology, Molecular BiologyPrelims + MainsThe Hindu · Science Two papers in Cell and Science report a bacterial enzyme, DRT3b, that builds a DNA strand with a defined sequence without any nucleic-acid template — the protein itself dictates the order. It pushes against, but does not overturn, the central dogma of molecular biology. ◈ Basics First — The Central Dogma DNA stores genetic information; it is copied (transcription) into messenger RNA (mRNA), which is read (translation) to make proteins. Francis Crick (1958) stated that information can pass from nucleic acid to nucleic acid, or nucleic acid to protein, but never from protein back to nucleic acid or to another protein. Why information is lost — the genetic code is degenerate: 64 codons code for 20 amino acids, so many DNA sequences give the same protein. A protein’s sequence cannot tell you its original DNA. Template — an existing strand that guides the order of nucleotides in a new strand. ▤ Static Anchor — How We Learnt DNA Is the Genetic Material Avery, MacLeod and McCarty (1944) — destroying DNA (but not protein or RNA) stopped bacterial transformation. Hershey and Chase (1952) — using phages labelled with radioactive phosphorus (DNA) and sulphur (protein), showed only DNA entered bacteria. Watson and Crick (1953) — double helix model of DNA. Temin and Baltimore (1970) — discovered reverse transcriptase in retroviruses (e.g. HIV), which copies RNA into DNA. Crick clarified that this nucleic-acid-to-nucleic-acid flow did not violate his rule. Figure 9 — Where DRT3b fits in the flow of genetic information DNARNAProteintranscriptiontranslationreverse transcription(retroviruses, 1970)replicationDRT3b: protein dictates a simple DNA sequence (CACACA…) without a nucleic-acid template— “a toe over the line”, not a reversal of protein → nucleic acid information transferCrick (1958): information can flow nucleic acid → nucleic acid → protein, but not back out of protein Reverse transcription was already allowed; DRT3b is unusual because a protein, not a template, sets the DNA sequence. What was discovered Defence-associated reverse transcriptases (DRTs) help bacteria fight bacteriophages (viruses that infect bacteria) by making unusual DNA molecules. The new family, DRT3, has two enzymes: DRT3a makes the first DNA strand using an RNA template (as usual), while DRT3b makes the second strand with no template. DRT3b produces an ordered repeat of cytosine and adenine (CACACA…) — unlike terminal deoxynucleotidyl transferase, which adds nucleotides randomly. Function — when a phage disables the cell’s “brakes”, this DNA builds up and pushes the infected cell into dormancy, stopping the phage from spreading (a form of abortive infection). Does it break the central dogma? No — the core principle is that a protein’s sequence cannot be used to reconstruct the DNA that encoded it. DRT3b does not do this; it produces only a simple, fixed pattern. But it is conceptually new — a protein specifying a defined DNA sequence without a template had not been seen before. Other known “deviations” — prions (misfolded proteins that pass their shape to other proteins), telomerase (a reverse transcriptase that extends chromosome ends) and RNA viruses that copy RNA directly. Why it matters Bacterial immunity research has already produced powerful tools such as CRISPR-Cas9 (Nobel Chemistry 2020); DRTs could yield new biotechnology tools. Better understanding of phage defence can support phage therapy against antimicrobial resistance. It shows that scientific “laws” in biology are working descriptions, open to refinement as evidence grows. ✎ Mains Practice Question Explain the central dogma of molecular biology. How have discoveries such as reverse transcriptase and template-free DNA synthesis by bacterial enzymes refined our understanding of it? 10 marks · 150 words Environment & EcologyGeneral Studies Paper III 07 National Coastal Mission 2.0: Guidelines Released for ₹767-Crore Coastal Resilience Scheme GS-III · Environment — Conservation, Disaster Management; Blue EconomyPrelims + MainsPIB · Ministry of Environment, Forest and Climate Change The MoEFCC has released implementation guidelines for National Coastal Mission 2.0, a Central Sector Scheme to strengthen the resilience and sustainability of India’s coastal regions and support the blue economy. ◈ Basics First Coastal resilience — the ability of coastal ecosystems and communities to withstand and recover from cyclones, storm surges, erosion and sea-level rise. Blue economy — economic activity based on oceans and coasts (fisheries, ports, shipping, tourism, marine energy) that keeps marine ecosystems healthy. Central Sector Scheme — fully funded by the Centre, unlike a Centrally Sponsored Scheme, where Centre and States share costs. ▤ Scheme at a Glance Outlay: ₹767 crore; Tenure: until 2030-31. Nodal Ministry: Environment, Forest and Climate Change. Coverage: nine coastal States (Gujarat, Maharashtra, Goa, Karnataka, Kerala, Tamil Nadu, Andhra Pradesh, Odisha, West Bengal) and four UTs (Dadra & Nagar Haveli and Daman & Diu, Puducherry, Lakshadweep, Andaman & Nicobar Islands). Components: vulnerability assessments, ecosystem restoration, pollution management, biodiversity conservation, sustainable tourism, coastal spatial planning, research and capacity building. Approach: convergence with existing schemes; a whole-of-government approach with clear institutional roles and monitoring. 11,098.81 km India’s coastline (revised estimate) ~33.6% of shoreline eroding (NCCR, 1990–2018) ~4,992 sq km mangrove cover (ISFR 2023) Static Anchor — India’s coastal governance framework Coastal Regulation Zone (CRZ) Notification — first issued in 1991 under the Environment (Protection) Act, 1986; current version 2019, with zones CRZ-I to CRZ-IV. The Island Protection Zone Notification, 2019 covers Andaman & Nicobar and Lakshadweep. Integrated Coastal Zone Management (ICZM) Project (World Bank-supported, from 2010) — piloted in Gujarat, Odisha and West Bengal; created the National Centre for Sustainable Coastal Management (NCSCM), Chennai. Related initiatives: MISHTI (mangrove plantation, 2023), Blue Flag beach certification (Foundation for Environmental Education, Denmark), and the Sagarmala programme (2015). Why it matters India’s coasts face frequent cyclones (more intense in the Arabian Sea in recent years), erosion and sea-level rise. Mangroves, coral reefs and seagrasses act as natural barriers and are major blue carbon sinks. Coastal districts support fisheries, ports and tourism and a large share of India’s population. The critical view Modest outlay — ₹767 crore over about five years across 13 coastal States and UTs is limited relative to the scale of the risk. Development vs conservation — ports, tourism and infrastructure under the blue economy can conflict with ecosystem protection; CRZ relaxations have often been criticised. Fishing communities — need a real voice in planning so that conservation does not displace traditional livelihoods. Implementation — success depends on Centre–State coordination and integrating climate projections into coastal planning. ✎ Mains Practice Question India’s coastal regions face rising climate and development pressures. Discuss how National Coastal Mission 2.0 can help balance coastal resilience with the goals of the blue economy. 10 marks · 150 words History, Art & CultureGeneral Studies Paper I 08 Five New Sites and Proposals Added to India’s UNESCO Tentative List, Taking the Count to 78 GS-I · Art & Culture — Architecture, Painting, Heritage ConservationPrelims + MainsNews On AIR · 29 September 2026 Four sites — the Bagh Cave paintings, the Group of Temples of the Chambal Valley, the Gupta-era Udayagiri Caves and Ginnorgarh — and a serial transnational proposal, the Sites of Satyagraha (India–South Africa), have been added to India’s UNESCO Tentative List, which now has 78 entries. ◈ Basics First World Heritage Site — a place recognised by UNESCO as having Outstanding Universal Value (OUV) for all humanity. Tentative List — a country’s shortlist of sites it intends to nominate. A site must be on it for at least one year before a full nomination. Inclusion is not inscription. Serial nomination — several separate sites nominated together as one property because they share a common theme. Transnational nomination — a property whose components lie in more than one country, nominated jointly. Figure 10 — From Tentative List to World Heritage inscription 1.

Inscriptionon the WorldHeritage ListTest: Outstanding Universal Value — meet at least one of 10 criteria (i–vi cultural, vii–x natural),plus integrity, authenticity (for cultural sites) and an adequate protection and management system The Tentative List is only the first step; evaluation by the advisory bodies and a Committee decision follow. The new additions Bagh Caves (Dhar district, Madhya Pradesh) — a group of nine Buddhist rock-cut caves of about the 5th–6th century CE, known for murals stylistically close to Ajanta; Cave 4, the “Rang Mahal”, preserves the best-known paintings. Group of Temples of the Chambal Valley — the region is known for early medieval temple clusters such as Bateshwar (Morena), built largely under the Gurjara-Pratiharas (8th–10th century), and the circular Chausath Yogini temple at Mitaoli. Udayagiri Caves (Vidisha district, Madhya Pradesh) — about 20 rock-cut shrines of the early 5th century CE, linked by inscription to Chandragupta II; famous for the colossal Varaha (boar incarnation of Vishnu) panel, among the earliest surviving Hindu cave temples. Ginnorgarh (near Bhopal, Madhya Pradesh) — a hill fort associated with the Gond rulers, recognised for its tribal legacy; linked in local history with the Gond queen Rani Kamlapati. Sites of Satyagraha (India–South Africa) — a serial transnational proposal on the places where Gandhian non-violent resistance developed. Figure 11 — Rock-cut caves at Bagh, Madhya Pradesh The caves are cut into a sandstone hillside above the Baghani river; the pillared verandahs once carried the murals that give the site its importance. Image as supplied; reproduced with credit for educational use. ▤ Prelims Traps Two Udayagiris: the Gupta-era Udayagiri (Vidisha, Madhya Pradesh — Hindu, 5th century CE) is different from Udayagiri–Khandagiri near Bhubaneswar, Odisha (Jain caves of King Kharavela, c. 1st–2nd century BCE). Bagh vs Ajanta: both have Buddhist murals of a similar period, but Bagh is in Madhya Pradesh, Ajanta in Maharashtra (World Heritage Site since 1983). Madhya Pradesh’s existing World Heritage Sites: Khajuraho (1986), Sanchi (1989) and Bhimbetka (2003). ◈ Static Anchor — The World Heritage System World Heritage Convention — adopted by UNESCO in 1972 (Paris); India ratified it in 1977. World Heritage Committee — 21 State Parties; India hosted its 46th session in New Delhi in July 2024. Advisory bodies: ICOMOS (cultural sites), IUCN (natural sites) and ICCROM (conservation training). India’s nodal agency: the Archaeological Survey of India (ASI), under the Ministry of Culture. India’s tally: 44 World Heritage Sites after the Maratha Military Landscapes were inscribed in 2025 — 36 cultural, 7 natural and 1 mixed (Khangchendzonga National Park, 2016). The first, in 1983, were Ajanta, Ellora, Agra Fort and the Taj Mahal. Earlier transnational precedent: The Architectural Work of Le Corbusier (2016), shared by seven countries, includes Chandigarh’s Capitol Complex. Background — satyagraha’s two homes Gandhi lived in South Africa from 1893 to 1914; the 1893 eviction from a train at Pietermaritzburg is often cited as a turning point. He first used satyagraha in 1906 against the Asiatic Registration law in the Transvaal, and set up community settlements at Phoenix (1904) and Tolstoy Farm (1910). In India, it shaped Champaran (1917), Kheda and the Ahmedabad mill strike (1918), and the Salt Satyagraha / Dandi March (1930). Significance and challenges Wider representation — the list now includes Buddhist art, early Hindu cave architecture, medieval temples and tribal (Gond) heritage, beyond the well-known monuments. Cultural diplomacy — the Satyagraha proposal links shared India–South Africa history and projects India’s soft power. A long queue — with 78 entries and, under current rules, generally one nomination per country per year, most sites will wait years for evaluation. Conservation burden — fragile murals (Bagh’s paintings have suffered damage over time) and scattered temple ruins need scientific conservation, buffer zones and local community involvement. ✎ Mains Practice Question India’s UNESCO Tentative List now includes rock-cut caves, mural traditions, temple clusters, tribal heritage and a transnational proposal on satyagraha. Discuss the significance of such diversification for heritage conservation and cultural diplomacy, and the challenges in converting tentative listings into inscriptions. 10 marks · 150 words
