The Minister said the agreement opens opportunities for farmers, fishermen, MSMEs, innovators, startups, women entrepreneurs, manufacturers and service providers on both sides, and that sensitive sectors were protected in the negotiation. He described the combined market as 2 billion people, about a quarter of global GDP, a third of world trade and roughly USD 24 trillion in size. He noted that all 27 EU member states were on board and keen to complete formalities early — unanimity he described as uncommon in the European context. India–EU trade has roughly doubled over the last decade to nearly USD 140 billion. The static spine: how a 19-year negotiation reached conclusion 2007 — Negotiations launched, then called the Broad-based Trade and Investment Agreement (BTIA). That is the name UPSC has historically used for this file. 2013 — Talks effectively froze over automobile tariffs, wines and spirits, dairy access, services mobility (Mode 4) and India’s Bilateral Investment Treaty regime. June 2022 — Negotiations relaunched, on three parallel tracks: the FTA, an Investment Protection Agreement and a standalone Geographical Indications agreement. The India–EU Trade and Technology Council (TTC), set up in 2022, ran alongside as the non-trade rail. 27 January 2026 — Negotiations concluded and announced at the India–EU Summit in New Delhi, the day after the European Council President and the European Commission President attended the Republic Day celebrations as chief guests. Now — legal scrubbing and translation into all official EU languages, then Council decision and signature, then European Parliament consent. Entry into force is widely expected around 2027.

The exam-relevant distinction: “concluded” (January 2026) is a political milestone; the treaty binds only after signature and ratification. ▤ Agreement at a Glance Parties: India and the European Union (27 member states). Original framework: Broad-based Trade and Investment Agreement (BTIA), launched 2007. Conclusion of negotiations: 27 January 2026, India–EU Summit, New Delhi. Combined market: ~2 billion people; ~25% of global GDP; ~⅓ of world trade (as stated by the Government). Current bilateral trade: nearly USD 140 billion, roughly doubled in a decade. The EU is among India’s largest goods-trade partners. Tariff coverage: the European Commission has described elimination or reduction covering roughly 96–97% of tariff lines on both sides, phased over about seven years. Indian export gains: textiles and apparel, leather and footwear, marine products, gems and jewellery, engineering goods, pharmaceuticals — sectors that faced EU duties of up to 12–26%. EU export gains: automobiles (phased duty reduction under a quota), machinery, chemicals, medical devices, wines and spirits, olive oil and processed foods. Excluded / protected on India’s side: dairy, rice, sugar, wheat; limited opening in public procurement. Excluded on the EU side: beef, poultry, rice, sugar — the sensitivities that stalled the EU–Mercosur deal. Not included: the Investment Protection Agreement and the Geographical Indications agreement are separate, still-live negotiations. The Belgium layer — why this particular bilateral dialogue Belgium is not an incidental partner in an EU trade conversation. It hosts the EU institutions, and the Port of Antwerp-Bruges is Europe’s second-largest seaport — the physical channel through which a large share of Indian cargo would enter the single market. Gems and jewellery: the Minister proposed co-creation and design including lab-grown diamonds, and mutual recognition in technology and certification, anchored on the Antwerp–Mumbai–Surat triangle. Antwerp is the historic global rough-diamond trading hub; Surat cuts and polishes the overwhelming majority of the world’s diamonds. Semiconductors: pairing Belgian micro-electronics research with Indian scale to build a design-to-fabrication ecosystem. Belgium hosts imec, one of the world’s leading nanoelectronics R&D centres. Green hydrogen: the Minister suggested the National Green Hydrogen Mission could supply Europe through Antwerp-Bruges’ bunkering and green-shipping infrastructure. Defence and advanced manufacturing: MoUs were exchanged with John Cockerill; areas named included counter-drone systems, electronic warfare, precision munitions and Western export corridors for India-designed BrahMos and Pinaka systems. Agriculture and food processing: potato processing, cold chains and sustainable agri-value chains. Diplomatic lineage: Belgium was among the first European states to establish diplomatic relations with independent India, in 1947. Claims made about India’s own capability — recorded as stated Semicon India was described as fully subscribed, with Semicon India 2.0 launched at a stated outlay of USD 14 billion, expected by the Government to catalyse around USD 70 billion of investment. The nuclear programme was described as opened to the private sector after six decades through the Shanti Act, with a stated plan of 100 GW of nuclear capacity over twenty years as baseload. The space sector, put at USD 8.5 billion today, is projected by the Government to reach USD 44 billion in eight years. A USD 12 billion research and innovation fund was cited, which the Minister argued delivers PPP-adjusted innovation output far above its nominal value. Read the economy figures with care: the Minister’s USD 4 trillion refers to India’s nominal GDP, while the “third-largest economy at USD 20 trillion” refers to the purchasing-power-parity measure. The two are different scales and should not be conflated in an answer. The critical view CBAM was not resolved. India did not secure an exemption from the EU’s Carbon Border Adjustment Mechanism, in force in its definitive phase from January 2026. For Indian steel, aluminium, cement and fertiliser exporters, the carbon charge can offset much of the tariff gain. The FTA reportedly opens only a technical dialogue, alongside EU support of about €500 million for Indian industrial decarbonisation. Non-tariff barriers now bind harder than tariffs. EU Sanitary and Phytosanitary standards, pesticide-residue limits, the Deforestation Regulation and the corporate sustainability due-diligence rules apply regardless of tariff lines, and Indian agri and MSME exporters have historically struggled with them. Data adequacy is unresolved. Despite the DPDP Act, 2023, India has not been granted GDPR adequacy status, so Indian IT and ITES firms continue to carry compliance costs on European data. Ratification is not automatic. Consent of the European Parliament is required, and agricultural and labour-standards lobbies have delayed comparable agreements. The Mercosur experience is the standing cautionary example, though the India deal excludes the farm products that made Mercosur toxic. Asymmetry within India. Gains concentrate in textiles, leather, marine products and gems — labour-intensive and welcome — but automobile, wine and spirits liberalisation exposes domestic segments, and public procurement and dairy were shielded precisely because the domestic cost would have been political. Strategic reading. The timing is inseparable from tariff turbulence in US trade policy and from both partners’ China-plus-one diversification. This is de-risking as much as it is commerce. Institutions & terms for Prelims BTIA — the 2007 name of these negotiations. India–EU TTC — Trade and Technology Council, 2022; the EU has only one other such council, with the United States. CBAM — EU carbon border levy; transitional phase from October 2023, definitive phase from January 2026. Mode 4 — movement of natural persons under GATS; the professional-mobility chapter is India’s long-standing ask. TKDL — Traditional Knowledge Digital Library, relevant to the IP and traditional-knowledge provisions. Ratification path (EU): Council decision by qualified majority + European Parliament consent. (India): approval by the Union Council of Ministers — trade treaties are not ratified by Parliament in India. ✎ Mains Practice Question “The India–EU Free Trade Agreement resolves the tariff question but leaves the regulatory question open.” Examine this statement with reference to the Carbon Border Adjustment Mechanism, sanitary and phytosanitary standards, and data adequacy. 15 marks · 250 words Environment, Energy & EcologyGeneral Studies Paper III 02 Geothermal Energy: the science, the resource base, and India’s first wells at Puga Valley GS-III · Environment & Energy — Renewable Sources, Energy SecurityGS-I · Geography — Earth’s Interior, TectonicsPrelims + MainsPIB Backgrounder · Ministry of New & Renewable Energy · Release ID 2306688 Geothermal is the one renewable that runs round the clock without storage — and after decades of assessment, India has finally drilled the wells that could turn a mapped resource into a working megawatt. ◈ Background & Context A PIB backgrounder sets out India’s geothermal position following two policy-and-project milestones: the National Policy on Geothermal Energy notified in September 2025, and the commissioning of the country’s first two geothermal wells at Puga Valley, Ladakh, in July 2026. The Ministry of New and Renewable Energy (MNRE) is the nodal ministry for the policy. The wells were drilled by the ONGC Energy Centre, the R&D arm of ONGC, in collaboration with the Ladakh Administration and the LAHDC-Leh. Unlike solar and wind, geothermal supplies baseload power — it is not weather-dependent and needs no storage to be firm. The basics: where the heat comes from Earth’s interior is layered into a solid crust, a semi-solid mantle, and a core with a dense liquid outer part and a solid inner part. Temperature rises with depth — the mantle reaches about 3,700°C at the core boundary; the core itself runs to roughly 5,000–6,000°C. Two heat sources: radioactive decay of uranium, thorium and potassium in the crust and mantle, plus residual primordial heat from planetary formation. Transport mechanism: this heat drives mantle convection currents — the same currents that drive plate tectonics, earthquakes, volcanism and mountain building. Geothermal energy and seismicity share a single cause, which is why the two maps overlap. Trapping: in tectonically active zones, faults and fractures let hot material rise near the surface. Meteoric water percolating down is superheated and held in permeable reservoir rock under an impermeable cap — surfacing as hot springs, geysers and fumaroles where the seal leaks. India’s tectonic setting: the Himalayan geothermal belt owes its heat to the Indian plate’s collision with the Eurasian plate along the Indus Suture Zone, which is precisely why Puga and Chumathang are the country’s most promising sites.

Two ways to use the heat Power generation: deep wells bring hot water and steam to the surface; steam drives a turbine coupled to a generator; the spent fluid is condensed and reinjected into the reservoir. The cycle mirrors a thermal power plant, with underground heat substituting for fuel combustion. Direct-use applications: district heating, agriculture and greenhouse heating, aquaculture, and space heating and cooling — often the more economical route at moderate temperatures. Ground Source Heat Pumps (GSHPs) exploit near-surface stable temperatures for building heating and cooling. Frontier technologies: Enhanced Geothermal Systems (EGS) engineer permeability into hot dry rock by fracturing, and Advanced Geothermal Systems (AGS) use closed-loop circulation. Both decouple geothermal from naturally permeable reservoirs, widening the geography of what is exploitable. ▤ India’s Geothermal Resource Base — the numbers to remember Hot springs mapped by the Geological Survey of India: 381. Geothermal provinces identified: 10. Theoretical potential: about 10.6 GW (≈10,600 MW). Sites assessed as promising for power generation and direct use: 42. Installed commercial geothermal capacity in India: effectively nil — no commercial-scale plant yet operates. The 10 provinces: Himalayan; Naga-Lushai; Andaman & Nicobar Islands; Son-Narmada-Tapi (SONATA); West Coast; Cambay Graben; Aravalli; Mahanadi; Godavari; South Indian Cratonic. Global installed capacity (end-2025): 15.67 GW. Indonesia, the United States, the Philippines, Türkiye and New Zealand together hold roughly 67%. Figure 4 — GSI-identified geothermal sites across India Note the clustering along the Himalayan arc and the west-coast and SONATA rift belts — geology, not administrative geography, decides the map. Image courtesy Press Information Bureau / MNRE, 4 September 2026; reproduced with credit for educational use. Named sites worth memorising Ladakh: Puga, Chumathang, Gaik, Demchok, Nubra, Panamik. Himachal Pradesh: Manikaran, Kasol, Tattapani, Tapri. Uttarakhand: Tapoban, Joshimath, Gaurikund-area springs, Yamunotri. Chhattisgarh: Tattapani (Balrampur) — long studied as a candidate for an early demonstration plant. Note the name clash with Tattapani in Himachal; UPSC has used exactly this kind of duplication before. Jharkhand: Surajkund, Tantloi. West Bengal: Bakreshwar. Bihar: Bhimband (Munger). Odisha: Athmallik (Deulajhari), Attri. Maharashtra: Unhavare (Khed), Sativali, Tural. Gujarat: Tulsishyam, Dholera, Tuwa. Telangana: Manuguru. Madhya Pradesh: Anhoni. Haryana: Sohna. North-East: Tsachu (Tawang) and Takshing in Arunachal Pradesh; Polok and Yumthang-area springs in Sikkim. The Puga milestone — what was actually achieved Two wells, each 1,000 metres deep, drilled at over 14,000 feet altitude in Puga Valley, in Ladakh’s south-eastern Changthang region — among the highest-altitude geothermal drilling campaigns anywhere. Temperature recorded: up to 135°C at 400 metres, with deeper testing under way to establish commercial viability. Purpose: reservoir evaluation, and the technical basis for India’s first 1 MW demonstration geothermal power project. Institutional frame: a tripartite MoU of February 2021 between the Ladakh Administration, LAHDC-Leh and the ONGC Energy Centre, extended for five years in 2026. Phase II envisages surveys at Chumathang and a DPR for commercial-scale development. Why Ladakh: the UT’s carbon-neutrality goal, extreme winter heating demand, weak grid connectivity and the seasonal collapse of solar output make firm local baseload unusually valuable there. ▤ National Policy on Geothermal Energy, 2025 — at a glance Notified: September 2025. Nodal ministry: MNRE. Objective: establish geothermal as a mainstream renewable pillar through systematic exploration and deployment. Priorities: research, drilling, reservoir management and direct-use applications, including Ground Source Heat Pumps. Regulatory design: a clear framework to draw in both public and private participation. Distinctive provision: repurposing abandoned oil and gas wells for geothermal use — an asset-reuse route that lowers the sector’s biggest cost, drilling. Institutional build-out: a national geothermal data repository, pilot projects and Centres of Excellence. Stated applications: power, heating and cooling, agriculture and desalination; technology focus on geo-solar hybrids, EGS and AGS (government statement of intent). Related programme: the Renewable Energy Research and Technology Development (RE-RTD) scheme; MNRE sanctioned five geothermal R&D projects between July and August 2025. International cooperation: geothermal identified as a focus area with Australia, Iceland and the Kingdom of Saudi Arabia. Icelandic expertise (ÍSOR) has advised on the Puga drilling. Global context for comparison The world’s first geothermal electricity was generated at Larderello, Italy, in 1904 — the technology is over a century old, which is why it is described as proven rather than emerging. Iceland draws a large share of its primary energy and almost all of its space heating from geothermal; Kenya, through the Olkaria fields in the Rift Valley, gets a substantial share of its electricity from it. Both are rift or plate-boundary settings. Geothermal’s capacity utilisation factor typically exceeds 70–90%, against roughly 20% for solar PV and 25–30% for wind in India — the single strongest argument for it in a grid that is accumulating variable renewables. The critical view Potential is theoretical, not proven. The 10.6 GW figure is a resource estimate, not a bankable reserve. Most Indian springs are low-to-medium enthalpy — suited to binary-cycle or direct-use applications rather than conventional flash-steam power. The history is one of delay. Sites such as Tattapani and Puga have been under study since the 1970s; announcements have repeatedly outrun drilling. Even the current Puga MoU needed a five-year extension. Judge the sector by wells drilled, not policies notified. Cost structure is front-loaded and risky. Exploration drilling is expensive and can come up dry; without risk-mitigation instruments or a viability gap facility, private capital will not enter ahead of proven reservoirs. Environmental and social costs are real. Land use in fragile high-altitude ecology, induced seismicity associated with EGS fracturing, hydrogen sulphide and dissolved-solids emissions, and effects on hot springs that carry religious and tourism value — Manikaran and Puga are both culturally significant sites. Scale is the honest caveat. Against India’s renewable capacity in the hundreds of gigawatts, a 1 MW pilot is a technology demonstration. Its value is in de-risking, generating field data and building drilling capability — not in near-term generation. The strongest near-term case may not be electricity at all. Direct heat and GSHP applications in cold high-altitude regions and in industrial process heat could deliver more energy displacement per rupee than power generation. ✎ Mains Practice Question Geothermal energy offers round-the-clock renewable power, yet India’s installed geothermal capacity remains negligible despite a mapped potential of over 10,000 MW. Analyse the geological, technological and economic reasons for this gap, and assess whether the National Policy on Geothermal Energy, 2025 adequately addresses them. 15 marks · 250 words

Editorials, Opinions & Explained2 Items Core TopicImportantConcise Opinions & IdeasGS Paper II & III 01India & West Asia — from multi-alignment to hard-power02India's Model BIT Revision & Democratic Deficit Opinions & IdeasGeneral Studies Paper II & III 01 "The Gulf is calling and New Delhi must listen" — India's West Asia doctrine under pressure Core TopicOpinionGS-II · IR — India's Neighbourhood, West Asia, Indian Diaspora, Maritime SecurityGS-III · Internal Security — Maritime Threats, Energy SecurityPrelims + MainsThe Hindu / Indian Express · Shashi Tharoor · Op-Ed, 5 September 2026 A four-term MP and former UN Under-Secretary-General argues that India's decades-old posture of deliberate ambiguity in West Asia — treating the region as an economic hinterland rather than a strategic theatre — is reaching the end of its useful life. ◈ Background & Context India's West Asia policy has historically rested on a doctrine the author calls "deliberate ambiguity": cultivating economic ties with all major Gulf capitals — Riyadh, Tehran, Abu Dhabi, Tel Aviv — without tying itself to the security obligations of any. This "multi-alignment" served India when the United States functioned as the undisputed guarantor of regional stability and kept sea lanes open. India's three primary interests in the region have been: crude oil imports (roughly 60% of India's oil comes from the Gulf and West Asia), the Indian diaspora (approximately 9 million nationals in Gulf countries, among the largest concentrations of Indians abroad), and remittances (the Gulf is the largest single source of India's remittance inflows, which regularly exceed USD 100 billion annually across all countries). The region is also critical for the India–Middle East–Europe Economic Corridor (IMEC), announced at the 2023 G20 New Delhi Summit, which runs through Saudi Arabia, the UAE and Israel to European ports. The structural shift the author identifies The author's central argument is that the geopolitical conditions that made India's transactional posture workable have changed on two axes: American retrenchment and the emergence of new regional security architectures that exclude India. US "selective engagement": the argument that Washington's withdrawal from a guarantor role has created a "security vacuum" is contested but analytically significant. The collapse of the US-led regional security architecture after the 2003 Iraq War, the JCPOA withdrawal, and the uneven responses to Houthi attacks on Red Sea shipping have all contributed to this perception. The Mecca Joint Defence Agreement — the specific trigger for this piece — is described as bringing together Saudi Arabia, Türkiye and Pakistan into a collective defence arrangement. The author presents this as a hard-power realignment that India should read as a structural signal, not an isolated event. The pact links Gulf capital, Turkish naval and defence-technology capabilities, and Pakistani military manpower. India's absence: West Asian capitals, the author argues, no longer treat non-alignment or multi-alignment as a virtue. They seek security partners with credible hard-power commitments — and if India does not offer them, others will fill that role. Figure 1 — The Gulf region: key states, chokepoints and India's stakes The six GCC states plus Iraq form the core of India's West Asian engagement — oil supplier, remittance source, diaspora home and the land corridor for IMEC. The Strait of Hormuz (right edge) carries roughly 20% of global oil trade. What the author proposes — the "hard-power" doctrine shift Active maritime security partnerships at the Strait of Hormuz, Gulf of Oman, Gulf of Aden, Bab-el-Mandeb and the waters off the Somali coast — through joint patrols, permanent logistics-access arrangements and interoperable surveillance networks. Defence manufacturing and technology as leverage: offering Gulf states Indian platforms (BrahMos, Pinaka are named) and embedding bilateral and "minilateral" security frameworks with the UAE, Israel and Saudi Arabia. Strategic deterrence without Cold War-style entanglement — the stated aim is a "deterrence web" that safeguards Indian interests and reassures partners without locking India into the obligations of a formal alliance. Workforce and diaspora diplomacy as a supporting frame: mutual recognition of qualifications, joint skills programmes. The chokepoints at stake — for Prelims and Mains Figure 2 — India's maritime exposure: three chokepoints, one corridor Strait of HormuzBetween Iran & Oman~20% global oil trade~⅓ of LNG tradeIndia's primary oil routeBab-el-MandebBetween Djibouti & YemenGateway to Red Sea /Suez Canal corridorHouthi disruptions activeStrait of MalaccaBetween Malaysia & Indonesia~40% global tradeby volumeIndia's eastward trade routeIndia–Middle East–Europe Economic Corridor (IMEC) — announced G20 New Delhi 2023India → UAE → Saudi Arabia → Jordan / Israel → Greece → EuropeRail, sea and data cable corridor; competes with China's BRI as an alternate connectivity routeSecurity of Gulf partners is a prerequisite for IMEC viability — the strategic link the article makes IMEC makes the Gulf's security directly relevant to India's connectivity ambitions — instability at any node in the land or sea segment compromises the corridor. Why this matters — the vulnerabilities the author maps Energy fragility: drone strikes on Gulf oil infrastructure (Abqaiq 2019 is the reference case; Houthi strikes have added to this record) demonstrate that even the most capital-intensive facilities remain vulnerable to low-cost asymmetric attacks. India currently imports roughly 85% of its crude; the Gulf accounts for a disproportionate share. Diaspora exposure: approximately 9 million Indians live and work in Gulf countries. Regional instability — as experienced during the Kuwait evacuation in 1990 (Operation Pawan in Kuwait / Operation Safed Sagar) — can trigger rapid, costly evacuation requirements. India has successfully evacuated nationals from Yemen (Operation Raahat, 2015) and Lebanon — the operational capability exists, but it is reactive rather than deterrent. The IMEC dimension: the piece implicitly frames IMEC security as contingent on Gulf stability. The corridor runs through Saudi Arabia and the UAE, whose security posture the Mecca Agreement is now partly reshaping. Supply-chain contagion: the Red Sea disruptions triggered by Houthi operations in 2024–25 added roughly 10–14 days to Asia–Europe shipping via the Cape of Good Hope reroute, sharply raising freight costs and demonstrating exactly the fragility the author describes. The critical view — what the argument oversimplifies Multi-alignment is not the same as passivity. India's Operation Raahat (Yemen), its counter-piracy deployments in the Gulf of Aden under the Combined Maritime Forces, and the India–UAE CEPA (2022) and the India–Saudi Arabia Strategic Partnership Council (2019) are evidence of active, if quiet, engagement. The argument conflates diplomatic restraint with strategic absence. The "Mecca Agreement" is contested. The pact's precise scope, binding commitments and operational content are not yet clear in open sources. Treating it as a fully formed counter-architecture risks overstating its cohesion — Saudi–Pakistani relations have historically been transactional rather than deeply strategic, and Saudi–Turkish interests diverge on several regional files (Muslim Brotherhood, Libya, Qatar blockade legacy). Hard-power projection carries real costs. India's naval capacity, while growing, is already stretched across the Indian Ocean, the South China Sea and its own waters. Permanent logistics access in the Gulf would require basing agreements that could complicate India's other relationships, particularly with Iran (Chabahar dependency) and with states that view external military presence with suspicion. The Iran factor. Any India–Gulf security architecture that excludes or alienates Iran complicates the Chabahar port project, cuts across India's Eurasian connectivity ambitions via the International North–South Transport Corridor (INSTC), and risks losing the leverage India has historically derived from its neutrality on the Sunni–Shia axis. Partisan authorship: Tharoor writes as an Opposition MP and former UN official; his policy preferences should be read alongside the present government's stated approach, which has been to deepen bilateral ties through economic and defence mechanisms rather than formal security architecture. Concepts and acronyms for Prelims GCC — Gulf Cooperation Council: Saudi Arabia, UAE, Kuwait, Qatar, Bahrain, Oman. Bab-el-Mandeb — strait between Yemen (Djibouti coast) and the Horn of Africa; entry to the Red Sea and Suez route; Houthi operations since October 2023 have effectively disrupted the lane for many carriers. Strait of Hormuz — between Iran and Oman; roughly 20% of global oil and about one-third of global LNG pass through it; Iran has threatened closure multiple times. IMEC — India–Middle East–Europe Economic Corridor; announced September 2023 at G20 New Delhi; a railway and sea-lane corridor through UAE, Saudi Arabia, Jordan/Israel and Greece, intended partly as a BRI alternative. Operation Raahat (2015) — India's evacuation of approximately 4,741 Indian nationals and 960 foreign nationals from conflict-affected Yemen, across 26 flights and 7 naval voyages; the largest Indian civilian evacuation since the Gulf War airlift. INSTC — International North–South Transport Corridor: India–Iran–Russia–Central Asia rail and road corridor; India's stake in this route constrains how far it can oppose Iranian interests. Minilateral — a small, issue-specific coalition of like-minded states, distinct from a treaty alliance; the Quad is the most prominent contemporary example. ✎ Mains Practice Question "India's traditional 'multi-alignment' in West Asia served it well when the United States was the regional security guarantor, but the structural shifts now underway demand a more assertive posture." Critically examine this argument with reference to India's energy security, diaspora interests, the IMEC corridor, and the constraints imposed by the Iran relationship and India's naval capacity. 15 marks · 250 words 02 Revising India's Model BIT: the case for a consultative process and democratic accountability ImportantOpinionGS-II · Polity & Governance — Treaty-Making, Parliamentary Oversight, International AgreementsGS-III · Economy — Foreign Investment, Trade Policy, Dispute ResolutionPrelims + MainsThe Hindu / Indian Express · Prabhash Ranjan, Jindal Global Law School · Op-Ed, 5 September 2026 A professor who was part of the Law Commission's BIT expert team argues that India is about to revise its 2015 Model BIT without the consultative process that would give the outcome legitimacy — and that this "democratic deficit" is the more serious problem, not just the legal text. ◈ Background & Context A Bilateral Investment Treaty (BIT) is an agreement between two states that sets the terms under which each country's investors can operate in the other's territory, including protections against expropriation, guarantees of fair treatment, and access to international arbitration in disputes with the host government. India signed around 80 BITs through the 1990s and 2000s, mostly based on a standard UNCTAD template that gave broad rights to foreign investors. Between 2011 and 2016, India faced a string of international arbitration claims — notably from Vodafone, Cairn Energy and White Industries — running to billions of dollars, arising from domestic regulatory and tax actions. In response, India unilaterally terminated most of its BITs between 2016 and 2018, serving notice on over 50 treaties. It also adopted a new Model BIT in December 2015, after a public consultation and Law Commission review, as the basis for future negotiations. The 2015 model was explicitly designed to swing the balance toward the state's right to regulate — narrowing investor protections relative to international norms, restricting the scope of investment covered, requiring domestic exhaustion before international arbitration, and limiting fair-and-equitable-treatment clauses. India has since concluded very few BITs based on the 2015 model; the Finance Minister in the Union Budget 2025 signalled that the model would be revamped, and a revised draft is reportedly near cabinet approval. The core legal argument: what needs to change in the substance The 2015 model tilts too far toward the state. The author and others have argued that the model excludes pre-establishment rights (the right to enter and invest, not just protections after investment), imposes a mandatory domestic litigation filter before international arbitration, and so narrows the definition of "investment" that many modern investments — including contractual and intellectual-property claims — may fall outside it. What the revised model is expected to address (reported, not confirmed): easier access to international arbitration, stronger and more predictable fair-and-equitable treatment, and investment-facilitation measures that make India a more legible destination for foreign capital. The balancing act: pulling the pendulum back toward investor protection without creating the liability exposure India faced under the old treaties — particularly around tax policy, where the retrospective-taxation episode was the proximate cause of several arbitration claims. Figure 3 — The BIT spectrum: investor protection vs. state's right to regulate ← Investor-protection poleState's right to regulate pole →Pre-2015India BITs(UNCTAD model)Revised Model BIT(expected — pulling back to centre)2015 Model BIT(state-tilted;few takers)Global norm (UK, EU, Canada): investor protections balanced with public-policy carve-outs. The revision is intended to move the pendulum back toward the centre without re-creating the unlimited liability exposure of the pre-2015 generation. The procedural argument: democratic deficit — the article's main contribution The author's more original point is not about what the treaty should say, but about how the revision process should work. He introduces the concept of "democratic deficit" into the BIT debate. "Democratic deficit" refers — originating in European debates about EU institutions — to the gap between decisions taken by technocrats or executives and the oversight of elected legislatures or affected citizens. In the treaty context: international economic agreements with binding domestic consequences are negotiated behind closed doors by officials, with limited parliamentary visibility. India's constitutional position on treaties: unlike legislation, treaties in India are concluded by the executive under the prerogative power of the Union. Parliament does not ratify trade or investment treaties; it does not vote on them. This places India close to the Westminster tradition but distant from the US system (Senate ratification) or the EU system (European Parliament consent for trade agreements). What other countries do: The UK and Australia place negotiated treaty texts before Parliament before ratification, under a "constitutional convention" or statutory requirement (the UK has the Constitutional Reform and Governance Act 2010). Norway held two rounds of public consultation — 2008 and 2015 — on its model BIT. Colombia released its model for public comment. India itself, in March 2015, circulated its draft model BIT for public comment and engaged the Law Commission of India (LCI), which produced its 260th Report with expert recommendations — though not all were incorporated in the final text. The four-step process the author recommends: Form an external expert core team — international lawyers, economists, academics — as a sounding board. Invite industry bodies, arbitrators, law firms and civil-society organisations to submit views. Release the draft in the public domain for open comment. Place the draft on the floor of Parliament and engage relevant parliamentary standing committees — the author chairs the Standing Committee on External Affairs. The key qualifier: the process must not be a box-ticking exercise. The author explicitly calls for engagement with dissenting views — an acknowledgment that consultation can be formal without being substantive. Why this matters — the policy stakes Foreign investment flows: India attracted USD 70+ billion in FDI in 2023–24. A credible investment protection framework reduces the "regulatory risk premium" that foreign investors build into their cost of capital in India. The EU–India FTA (concluded January 2026) has a separate Investment Protection Agreement still under negotiation — the model BIT revision will shape that negotiation directly. Arbitration pipeline: India faces ongoing investment arbitration claims running to several billion dollars. Revising the model prospectively is neutral on existing claims, but a stronger treaty signals India's willingness to be held to higher standards going forward. Parliamentary oversight as a constitutional question: the broader issue — whether Parliament should have any role in treaty-making — is an unresolved one in Indian constitutional law. No statute requires parliamentary ratification of trade or investment treaties. This is the "democratic deficit" in the Indian institutional context, distinct from the procedural point about public consultation. Terms for Prelims BIT / Bilateral Investment Treaty — a treaty between two states protecting cross-border investments; typically includes Fair and Equitable Treatment (FET), Most-Favoured-Nation (MFN) and National Treatment (NT) clauses, and investor–state dispute settlement (ISDS). ISDS — Investor–State Dispute Settlement; allows foreign investors to sue host governments in international arbitration tribunals (ICSID, UNCITRAL rules), bypassing domestic courts. Law Commission of India 260th Report — the LCI's review of the draft 2015 model BIT; a notable example of expert statutory oversight of India's treaty-drafting process. All-affected principle — in democratic theory, the idea that all those whose interests are affected by a decision should have a role in making it. The author uses it to justify external consultation on the BIT. CRAG Act 2010 (UK) — Constitutional Reform and Governance Act; places a statutory duty on the UK government to lay treaties before Parliament for 21 sitting days before ratification. UNCTAD — United Nations Conference on Trade and Development; publishes model investment treaties and tracks global BIT networks. ✎ Mains Practice Question India's treaty-making process concentrates authority in the executive, with Parliament playing no formal role in ratification. Analyse the implications of this arrangement for democratic accountability, and assess whether India should introduce a statutory framework for parliamentary oversight of international economic agreements. 10 marks · 150 words

The Supreme Court has previously advocated raising the retirement age of district judicial officers from 60 to 62 years as an interim measure while longer-term judicial infrastructure is built. A September 1 order now converts this from suggestion to direction. A three-judge bench headed by CJI Surya Kant directed seven agreeing States — Chhattisgarh, Karnataka, Madhya Pradesh, Maharashtra, Sikkim, Tamil Nadu and West Bengal — to amend service rules within two months. Enhancement is subject to a suitability assessment at age 60 — officers of proven integrity and competence continue; the rest retire on schedule. The Madras High Court model of a pre-condition assessment was specifically commended as preventing "deadwood" from benefiting. Why States are hesitant — and why the court says they are wrong Stated objection 1 — financial burden: States fear the additional cost of maximum-scale salaries and enhanced retiral benefits for two extra years. The court quoted a 1992 judicial precedent holding this burden "negligible" against the societal benefit of experienced justice administration. Stated objection 2 — parity demands: States worry that other government employees will demand equivalent extension. The court called this "entirely misconceived" — judicial officers perform a specialised constitutional function that is not analogous to general services. The court's arithmetic: retaining an officer at 60 means paying retiral dues to the superannuated officer and simultaneously the salary of a newly recruited replacement. Extending service to 62 defers those retiral dues, yielding a net saving in the short run. Recruitment failures: the court noted that "most recruitment drives have not resulted in optimum recruitment or the filling up of sanctioned cadre strength" — vacancies persist even after drives, so losing experienced officers compounds the crisis. The states that have not agreed — and the court's response States directed to decide within two weeks include: Andhra Pradesh, Arunachal Pradesh, Assam, Bihar, Goa, Gujarat, Haryana, Himachal Pradesh, Jharkhand, Keralam, Manipur, Meghalaya, Mizoram, Nagaland, Odisha, Punjab, Rajasthan, Telangana, Tripura, Uttarakhand, Uttar Pradesh, NCT of Delhi, Jammu & Kashmir and Puducherry. Their responses ranged from outright refusal to "fence-sitting" — the court recorded both. The case is listed again in October. The bigger picture — judicial vacancy and pendency data District and subordinate courts carry the bulk of India's judicial backlog — estimated at 5.18 crore pending cases as of the September order. Supreme Court: ~80,000 pending cases. High Courts: over 60 lakh. Together, the combined national figure exceeds 5 crore. The All India Judges Association case (multiple rounds since 1992) is the constitutional spine of the Supreme Court's jurisdiction over service conditions of district judges. The Law Commission of India (230th Report) and DAKSH/Vidhi reports have all flagged vacancy-to-pendency links; the court has consistently held that vacancies cause delay rather than the reverse. ✎ Mains Practice Question The Supreme Court has characterised judicial pendency as a crisis threatening access to justice as a fundamental right. Analyse the structural causes of this crisis in India's district judiciary and evaluate the measures — including raising the retirement age of judicial officers — proposed to address it. 15 marks · 250 words Economy & StatisticsGeneral Studies Paper III 02 MoSPI releases National Accounts Statistics 2026 with base year 2022-23, updating GDP with new PPI, IIP and BkSPI series GS-III · Economy — National Income, GDP Measurement, Statistical SystemsPrelims + MainsPIB · MoSPI · 31 Aug 2026 The Ministry of Statistics and Programme Implementation has released the National Accounts Statistics 2026, shifting the price-index inputs for GDP estimation from the old WPI-based series to the new PPI, IIP and BkSPI series, all with base year 2022-23 — revising GDP figures for 2022-23 through 2025-26. ◈ Background & Context National income accounting in India uses price indices to separate real growth from inflation effects. The older Wholesale Price Index (WPI) was used as a deflator in multiple sectors, but WPI measures producer prices at the first point of sale and has a basket that had become outdated. Replacing it with the Producer Price Index (PPI), which better captures price movements across the production chain, improves the accuracy of real GDP estimates. Three new indices, all base year 2022-23, released June 2026: PPI — Producer Price Index: replaces WPI in national accounts; updated commodity basket dropping obsolete items, adding emerging ones; better maps price measures to national accounts activities. IIP (Index of Industrial Production) — new base 2022-23; uses PPI instead of WPI; wider coverage of items and quotations. BkSPI (Banking Services Price Index) — measures growth in actual volume and transactional activity of banking services over time; first-of-its-kind for India's financial sector. The publication covers 60 statements including Final Estimates for 2022-23 and 2023-24, First Revised Estimates for 2024-25, and Provisional Estimates for 2025-26. Supply and Use Tables (SUTs) for 2022-23 and 2023-24 have also been updated. What changed in the GDP numbers — and why At constant prices: revisions are most visible where PPI replaces WPI — primarily manufacturing, mining & quarrying, and trade services. The new IIP (mining) changes the constant-price GVA of Mining & Quarrying. At current prices: revisions in GVA are primarily linked to General Government and Departmental Enterprises — driven by updated Net Fixed Capital Stock and Consumption of Fixed Capital (CFC) estimates using the PPI series. 2025-26 revisions are broader because they additionally incorporate benchmark updates from the prior year, compounding the effect of new indices. Key aggregates covered: GDP, National Income, Per-Capita Income, Private Final Consumption Expenditure (PFCE), Government Final Consumption Expenditure (GFCE), Savings, and Gross Capital Formation broken down by asset type and institutional sector. Figure 1 — India's GDP deflation chain: old vs. revised methodology Old Methodology (pre-2026)WPI (Base 2011-12) as deflatorIIP (Base 2011-12) — older basketNo banking volume index→ Outdated baskets, WPI not production-stage specific2026revisionRevised Methodology (NAS 2026)PPI (Base 2022-23) — updated basketIIP (Base 2022-23) — uses PPI, widerBkSPI (Base 2022-23) — banking volume→ Aligns with international standards; better sectoral mapping The shift from WPI to PPI is the central methodological change; PPI measures prices at each stage of production rather than at first-point-of-sale, giving a more accurate deflator for sectoral GVA. Key terms for Prelims GVA (Gross Value Added) = GDP at market prices − product taxes + product subsidies. GVA is the building block; GDP is derived from it. Base year revision changes the reference point for constant-price calculations; both the level and growth rate of GDP can change when the base shifts. First Revised Estimates vs. Provisional Estimates vs. Advance Estimates: the sequence is Advance (Jan/Feb of the same year) → Provisional → First Revised → Second Revised → Final. CFC (Consumption of Fixed Capital) — the wearing out of fixed assets; NNP = GNP − CFC. Accurate CFC requires up-to-date capital stock estimates. SUTs (Supply and Use Tables) — input-output tables matching total supply of goods/services to their uses; used to cross-check consistency of national accounts. MoSPI — Ministry of Statistics and Programme Implementation; the nodal ministry for national accounts, CPI, WPI/PPI and other data. ✎ Mains Practice Question What is the significance of using the Producer Price Index (PPI) instead of the Wholesale Price Index (WPI) as a deflator in India's national income accounting? Discuss the implications of the base-year revision to 2022-23 for the measurement and interpretation of India's GDP growth rates. 10 marks · 150 words Science & TechnologyGeneral Studies Paper III 03 ISRO's GSLV-F17 successfully launches EOS-05, India's first dedicated imaging satellite in geosynchronous orbit GS-III · S&T — Space Technology, ISRO Missions, Earth ObservationPrelims + MainsThe Hindu · Indian Express · 5 Sep 2026 ISRO's Geosynchronous Satellite Launch Vehicle successfully placed the 2,367-kg EOS-05 into sub-geosynchronous transfer orbit on 5 September 2026 — India's first dedicated imaging satellite designed to operate from geosynchronous orbit at ~36,000 km, ending an eight-month launch hiatus after two consecutive PSLV failures. ◈ Background & Context Geosynchronous orbit (GEO) satellites remain stationary relative to the Earth's surface, enabling continuous coverage of the same region — unlike Low Earth Orbit (LEO) satellites which pass overhead for minutes at a time. A GEO imaging satellite provides near-real-time, persistent imagery of a fixed area, which is strategically valuable for disaster response, border surveillance, crop monitoring and weather forecasting. ISRO's recent launch failures: PSLV-C61 (18 May 2025) and PSLV-C62 / EOS-N1 (12 January 2026) both failed. Seven missions were scheduled for Q1 2026 but none took place as ISRO adopted a "cautious approach" and conducted failure reviews. EOS-05 also compensates for the loss of EOS-03 (GISAT-1), which was lost in the GSLV-F10 failure in August 2021 — another GEO imaging attempt that failed at the cryogenic stage. This was the 19th GSLV mission and the 107th launch from Sriharikota (Satish Dhawan Space Centre). Figure 2 — EOS-05: mission profile and key facts EOS-05 is at sub-GTO immediately after launch; ISRO will raise the orbit in stages to place it on the geo platform. Image courtesy The Hindu, 5 September 2026; reproduced with credit for educational use. Technical details — the GSLV and its cryogenic stage Vehicle: GSLV (Geosynchronous Satellite Launch Vehicle) — a three-stage rocket. Stage 1 solid, Stage 2 liquid (Vikas engine), Stage 3 cryogenic (CE-7.5 engine using liquid hydrogen and liquid oxygen). Height: 51.7 metres. Lift-off mass: 420.5 tonnes. Payload to GTO: ~2,500 kg. EOS-05 at 2,367 kg is the heaviest satellite ever launched by GSLV — exceeding earlier payloads by progressively optimising structural mass and propulsion systems. Sub-GTO (sub-geosynchronous transfer orbit) is the initial parking orbit; ISRO will use the satellite's onboard propulsion to raise it to GEO (~35,786 km, 0° inclination). The satellite's solar panels have deployed; all valves are confirmed operating; health is described as nominal by ISRO. What EOS-05 does — and why GEO imaging matters Near real-time imaging from a fixed vantage point; unlike polar-orbit satellites that image a location every few days, GEO imaging provides continuous or near-continuous coverage of the same area. Applications: agriculture (crop health, irrigation monitoring), environment (vegetation, floods, fires), disaster management (near-real-time imagery during cyclones, floods), and strategic / "national activities" — the phrase ISRO uses for defence-related earth observation. Multi-band capability and a nine-year operational life. India's imaging satellite fleet now includes LEO satellites (Resourcesat, Cartosat series) for detailed mapping and the newly added GEO layer for continuous monitoring — complementary, not competing, capabilities. The GSLV's cryogenic history — context for Prelims India developed its own cryogenic engine (CE-7.5) after technology denial by Russia under US pressure in the 1990s — the episode directly fuelled India's indigenous cryogenic programme. GSLV's first successful cryogenic flight was GSLV-D5 (January 2014). GSLV-F10 (August 2021) was a cryogenic-stage failure. The GSLV-Mk III (LVM3) is a separate, heavier vehicle using the CE-20 cryogenic engine; it is not the same as the GSLV used for EOS-05. The distinction is frequently tested. ✎ Mains Practice Question Discuss the strategic and developmental significance of India placing an imaging satellite in geosynchronous orbit. How does EOS-05 complement India's existing earth observation capability, and what does it reveal about the role of indigenous launch vehicle development in India's space security? 15 marks · 250 words 04 Indian researchers produce first molecular profile of social spider Stegodyphus sarasinorum venom, finding anti-cancer and antimicrobial leads GS-III · S&T — Biotechnology, Drug Discovery, BiodiversityPrelims + MainsThe Hindu · 5 Sep 2026 Indian researchers from Sree Neelakanta Government Sanskrit College, Pattambi (Keralam), have published the first comprehensive molecular inventory of the venom gland of Stegodyphus sarasinorum — a permanently social colonial spider found across South Asia — identifying over 100 bioactive compounds with potential anti-cancer, antimicrobial and immune-related properties. Figure 3 — Stegodyphus sarasinorum: profile of a social spider S. sarasinorum is one of the few permanently social spider species worldwide; its colonial lifestyle makes it both an evolutionary curiosity and a rich source of bioactive venom compounds. ◈ Background & Context S. sarasinorum (family Eresidae) lives in permanent colonies in arid and semi-arid South Asia, constructs communal silk nests and hunts cooperatively — behaviours seen in fewer than 25 of the world's ~50,000 known spider species. The study was published in Scientific Reports (Springer Nature, open-access). It used three complementary analytical techniques: transcriptomics, proteomics and UHPLC-MS metabolomics — together covering proteins, their precursor transcripts and small-molecule metabolites. Key findings: 31 proteins identified by transcriptomics, 32 by proteomics, and 81 metabolites (amino acids, biogenic amines, organic acids) by UHPLC-MS. Venom gland extracts showed dose-dependent cytotoxicity against Dalton's Lymphoma Ascites (DLA) cancer cells in laboratory experiments. The researchers caution that laboratory cytotoxicity does not establish clinical efficacy; extensive validation including in-vivo studies and toxicity profiling would be required before any drug development. Why it matters for drug discovery Spider venoms are among the most complex biological mixtures known — products of millions of years of co-evolution with prey. They are an underexplored source of molecular scaffolds for drugs. India's biodiversity, including arachnid fauna, represents an underutilised resource for natural product chemistry. This study is part of a broader push to characterise Indian biodiversity at the molecular level before it is lost. ✎ Mains Practice Question India's biodiversity is often described as a strategic asset for biotechnology and drug discovery. Examine the steps needed to translate findings from biodiversity-based research — such as venom profiling of spider species — into commercially viable drugs, and the role of intellectual property and benefit-sharing frameworks in enabling this translation. 10 marks · 150 words Environment, Ecology & ClimateGeneral Studies Paper III 05 Hanging glaciers in Alaknanda basin: what the Nepal GLOF disaster tells India about its own Himalayan risk GS-III · Environment — Glaciology, Disaster Management, Climate Change ImpactsGS-I · Geography — Indian Rivers, Himalayan GeomorphologyPrelims + MainsIndian Express · Nature (Apr 2026) · 5 Sep 2026 Devastating flash floods in Nepal — triggered by a glacial collapse — have refocused attention on an April 2026 Nature study that mapped 219 hanging glaciers in the Alaknanda basin alone, with avalanche simulations projecting flows exceeding 50 metres in the Badrinath-Mana sector and a 120% increase in buildings at risk by 2030. ◈ Background & Context A "hanging glacier" is an ice mass perched on a steep slope, detached from the valley floor, typically above a cliff face. Unlike valley glaciers that flow slowly to lower altitudes, hanging glaciers can detach suddenly — releasing ice, rock and entrapped water in one catastrophic mass movement. The Nepal disaster of late August 2026 — involving a glacial collapse that triggered downstream flooding — is the immediate news peg. It resembles four major Indian incidents of the last fifteen years, most directly the Chamoli disaster of February 2021 in which a wall of ice and rock collapsed into the Rishiganga valley, destroying hydropower plants, sweeping bridges and killing over 200 people. The April 2026 study, led by Ashim Sattar (IIT Bhubaneswar) and Nandu Krishnan (IISc Bengaluru), is the first basin-scale hanging-glacier inventory for the Central Himalaya. It found 219 hanging glaciers in the Alaknanda basin, covering 71.7 ± 3.5 sq km with an estimated ice volume of 2.39 ± 0.42 km³. Nearly one-third of the unstable ice is concentrated in the Upper Alaknanda basin — the Badrinath-Mana sector. Figure 4 — Distribution of glaciers in the Alaknanda basin (Garhwal Himalaya) NH-58 (the Badrinath highway) passes through some of the highest glacier-risk zones in the basin — infrastructure lying directly in potential avalanche and GLOF pathways. Image: 'Basin-scale inventory and exposure assessment of hanging glaciers, Central Himalaya', Nature, April 2026; reproduced with credit for educational use. Figure 5 — Types of hanging glaciers identified in the Alaknanda basin Ramp-Slab and Terrace-Slab are the most numerous types; the Vishnuganga sub-basin (which includes the Badrinath-Mana sector) has the highest concentration. Image: 'Basin-scale inventory and exposure assessment of hanging glaciers, Central Himalaya', Nature, April 2026; reproduced with credit for educational use. How hanging glaciers form and why they are dangerous Formation: Climate warming causes valley glaciers to develop geometric instability — velocity can change by an order of magnitude over a short period, redistributing ice mass. Ice migrates to steep cliffs above valley floors, decoupling from the main glacier body to form hanging masses. Three types in the study: Ramp-Slab (inclined surface), Terrace-Slab (stepped terrain) and Terrace-Wedge (wedge-shaped, rarest). Ramp-Slab and Terrace-Slab are most numerous in the Alaknanda basin. Break-off mechanism: permafrost thaw beneath the glacier removes the frozen substrate that anchors ice to bedrock. When this "freeze glue" goes, the hanging mass detaches without warning. The Nepal event appears to involve exactly this mechanism — at a scale previously observed only in Greenland and Antarctica. Cascade of hazards: the initial ice avalanche entrains rock debris and water, reaching speeds that make evacuation impossible once underway. Where glacial lakes exist downstream, the impact wave can trigger a Glacial Lake Outburst Flood (GLOF), amplifying the disaster's downstream reach far beyond the immediate avalanche zone. Risk exposure in India — the numbers that matter Avalanche-related risk exposure in the Alaknanda basin is projected to increase with a 120% rise in buildings and infrastructure land at risk by 2030 compared to 2000. Population in at-risk areas is projected to grow by 17% over the same period — driven by development of pilgrimage and tourism infrastructure along NH-58 and associated valley settlements. Simulated avalanche flows in the Badrinath-Mana sector could exceed 50 metres in height — high enough to overtop most existing settlements and infrastructure. The Chamoli lesson vs. the Blatten contrast Chamoli 2021 (India): a massive ice-rock avalanche, likely from Raunthi peak, collapsed into the Rishiganga valley. Killed 200+. No prior monitoring; no early warning; no evacuation. Blatten 2025 (Switzerland): a large ice-rock avalanche buried most of the village of Blatten. One person died. Authorities and residents acted on precursory slope-instability signs months before — near-complete evacuation achieved. A March 2026 Nature study (Bhardwaj et al.) compared these two events and concluded: the difference was "not luck, but preparedness, monitoring, and rapid response." India's gaps: anticipatory monitoring systems are limited; the Himalaya's transboundary nature (India–Nepal–China) complicates joint early-warning infrastructure; attributing cascading hazards mid-event is still not standard practice in disaster response. Institutions and terms for Prelims GLOF — Glacial Lake Outburst Flood; occurs when a glacial lake (moraine-dammed or ice-dammed) catastrophically drains. NDMA has issued guidelines for GLOF risk reduction. Alaknanda River — one of the two headstreams of the Ganga (the other is Bhagirathi); joins at Devprayag. The basin covers major pilgrimage sites: Badrinath, Kedarnath, Joshimath. NH-58 — now NH-7 — the highway to Badrinath; passes through glacier-risk zones flagged in the study. ICCI — International Cryosphere Climate Initiative, Burlington, Vermont; the body that flagged the April 2026 study as a warning. Indus Suture Zone — the tectonic boundary between the Indian and Eurasian plates; the heat and deformation along this zone create both geothermal resources and cryospheric instability in Ladakh and the Garhwal-Kumaon arc. ✎ Mains Practice Question "The Himalayan cryosphere is moving from a predictable, slowly changing system to one characterised by sudden, catastrophic release events." In light of this shift, critically examine India's preparedness for glacial disasters, drawing on recent events and the gaps in monitoring, early warning and transboundary risk-management. 15 marks · 250 words 06 UN Environment Programme: 1.5°C target definitively breached, carbon removal at scale now the only remaining pathway GS-III · Environment — Climate Change, Paris Agreement, Carbon RemovalGS-II · IR — Global Environmental GovernancePrelims + MainsNew York Times · UNEP · 2–3 Sep 2026 A 141-page UNEP report formally declares that the world will breach the 1.5°C Paris target within "the next few years" and outlines a fallback pathway: limit the temperature overshoot to a peak of 1.8°C, then remove CO₂ from the atmosphere at an unprecedented scale to bring temperatures back down — a task scientists warn could take decades to achieve even a single decade of excess warming. ◈ Background & Context The Paris Agreement (2015) committed countries to limit warming to "well below 2°C" above pre-industrial levels, while "pursuing efforts to limit the temperature increase to 1.5°C". Scientists have warned for several years that 1.5°C was effectively unachievable without immediate, steep global emissions cuts that have not materialised. Current warming: global average temperature is approximately 1.4°C above pre-industrial levels. Carbon dioxide from fossil fuel combustion has been the primary driver. Current trajectory: based on existing national policies, the UNEP report projects warming of 2.6°C by end of century — far above both Paris targets. The policy-science disconnect: international climate conferences have continued to use "keeping 1.5 alive" rhetoric even as scientists privately concluded it was lost. This report — described as the "UN system catching up with reality" — formally ends that disconnect. UNEP Emissions Gap Reports have annually quantified the gap between pledged action and the action needed; this report goes further by changing the stated target itself. The new fallback framework — overshoot and removal Step 1 — limit the overshoot: keep peak warming at 1.8°C or below. The report describes even this as unlikely under current trends. Step 2 — remove carbon at scale: after peaking, draw down atmospheric CO₂ through Carbon Dioxide Removal (CDR) at a colossal rate to bring temperatures back down to 1.5°C eventually — potentially over 50 years to reverse a decade of excess warming. The UN calls this pathway "by no means an acceptable or preferred pathway. It is simply the best remaining option." Carbon removal: methods, scale and controversies Nature-based CDR: afforestation and reforestation — but at the scale required, tracts of land larger than entire US states would need to be forested. Conflicts with agriculture, reduced efficiency at higher temperatures, and wildfire risk all constrain this. Technology-based CDR: Bioenergy with Carbon Capture and Storage (BECCS) — burning biomass for energy, capturing the CO₂ emissions and storing them underground. Requires vast land for biomass and proven geological storage. Direct Air Capture (DAC) — machines that chemically extract CO₂ from ambient air. Current industrial capacity is extremely limited and cost per tonne is very high. Enhanced weathering — spreading silicate minerals on cropland to absorb CO₂ via chemical reactions. Promising but unproven at scale. The moral hazard critique: Climate Analytics and others warn the CDR pathway risks becoming a "call to apathy" — it could reduce pressure to cut emissions now. The report has also been criticised for not explicitly calling for a fossil fuel phase-out, even as countries committed to pivoting away from oil, gas and coal at COP28 in 2023. US withdrawal: the Trump administration's departure from Paris Agreement commitments removes the largest historical emitter from the global framework at the moment when the most ambitious action is needed. Impacts already locked in at current warming levels Intensifying heat waves, droughts, floods and wildfires are present at 1.4°C. At 1.5°C: coral bleaching will be near-total; extreme heat events will be significantly more frequent and intense. Irreversible changes: glacial loss, sea-level rise, and certain species extinctions are effectively locked in regardless of future mitigation. Tipping points: the report flags risks including weakening or collapse of the Atlantic Meridional Overturning Circulation (AMOC) — which carries warm tropical water northward — with potential to "reshape the world forever." Key terms for Prelims UNEP — United Nations Environment Programme, headquartered in Nairobi; publishes the annual Emissions Gap Report and the Adaptation Gap Report. Carbon overshoot — temporarily exceeding a temperature target before bringing temperatures back down through CDR. AMOC — Atlantic Meridional Overturning Circulation; a large ocean-current system that redistributes heat globally; weakening is already observed. DAC — Direct Air Capture; the technology-based CDR route currently at small scale; the US company Climeworks operates the largest plant in Iceland. COP28 (Dubai, 2023) — the climate summit at which countries agreed to "transition away" from fossil fuels; first explicit mention in a COP decision text. ✎ Mains Practice Question The UN has formally acknowledged that the 1.5°C Paris Agreement target will be breached and has proposed a framework of "overshoot and carbon removal." Critically examine the feasibility of this approach and its implications for global climate governance, with particular reference to the equity concerns of developing countries. 15 marks · 250 words Society, Heritage & ConservationGeneral Studies Paper I & III 07 Restoration at Saptakoteshwar Temple site in Goa's Divar island unearths relics spanning Kadamba and Vijayanagara periods (14th–16th century) GS-I · History & Culture — Medieval Dynasties, Goa, Temple Architecture, Colonial ImpactGS-III · Governance — Heritage Conservation, Kotiteerth CorridorPrelims + MainsIndian Express · 4–5 Sep 2026 Restoration work on Goa's Divar island at the site of the ancient Saptakoteshwar temple has yielded archaeological relics — including a Kirtimukh doorway motif, a carved pillar capital and parts of a Dev Khostam (idol platform) — confirming successive reconstructions from the Kadamba period through Vijayanagara rule before Portuguese destruction in the 16th century. Figure 6 — Artefacts from the Saptakoteshwar temple excavation, Divar, Goa The variety of stone typologies indicates reconstructions by different builders across centuries — Kadamba laterite succeeded by Vijayanagara-period stonework. Image courtesy Goa Chief Minister's Office / ANI; reproduced with credit for educational use. ◈ Background & Context Goa's pre-Portuguese history is among the most archaeologically understudied chapters of Indian heritage — partly because the Portuguese colonial administration and the Goa Inquisition systematically destroyed temples, converted sites and erased records. The discovery of multi-period relics at a single site is therefore significant for reconstructing that history. Saptakoteshwar is a major Shaiva deity; the original temple at Naroa, Divar Island, was associated with the Kadamba dynasty (10th–14th century), which ruled Goa from its capital at Chandrapur (modern Chandor). The temple was destroyed by the Bahmani Sultanate and rebuilt in 1391 by a minister in the Vijayanagara kingdom — the relics bear markers of both periods. Portuguese authorities destroyed the Vijayanagara-era temple in the 16th century during systematic temple demolitions in the "Old Conquests" (Tiswadi, Bardez, Salcete talukas). The deity's idol was secretly carried across the Mandovi River to Bicholim, where Chhatrapati Shivaji Maharaj established a new shrine in 1668 during his Surat expedition — this is the active temple today. The Goa government's Kotiteerth Corridor Development Project is developing the Divar site as a pilgrimage memorial, with a new temple proposed on 10,000 sq m. An expert committee recommends a Smarak Devalaya (temple memorial) in the erstwhile Old Conquests area. The artefacts and what they reveal Kirtimukh — a fierce, disembodied face motif traditional in Indian temple architecture; typically placed above door-frames (torana) as an apotropaic guardian. Its presence confirms this was a significant temple entrance. Carved pillar capital — the top portion of a structural column; the carving style can be dated and attributed to specific regional traditions. Dev Khostam — the platform on which a temple idol was placed; Konkani architectural term. Stone typologies: different stone types across the finds confirm successive phases of construction — Kadamba builders used local laterite; Vijayanagara patrons brought granite traditions from the Deccan. The finds were located along the old pathway between Koti Tirth (the sacred tank) and Madhavachi Talli, confirming the historical descriptions of a temple complex with a sacred corridor. Historical lineage: dynasties and their Goa connections Kadamba dynasty — the earliest historically attested Goa rulers; their inscriptions and temples date from the 10th–14th centuries; their capital Chandrapur gave Goa its oldest urban history. Bahmani Sultanate — the Deccan sultanate that controlled Goa in the 14th–15th centuries before the Portuguese arrival. Vijayanagara Empire — the South Indian empire whose patronage kept temple culture alive in Goa before Portuguese annexation; the 1391 reconstruction is a documented example. Goa Inquisition — Portuguese ecclesiastical court active in Goa from 1561 to 1812; enforced conversion, banned Hindu and Muslim practices, and oversaw systematic destruction of temples. Over 1,000 temples were destroyed in the Old Conquests according to the expert committee. ✎ Mains Practice Question Archaeological discoveries at pre-colonial temple sites reveal the layered civilisational history of India's coastal regions. Discuss the historical significance of the Saptakoteshwar temple site in Goa, tracing its trajectory from the Kadamba period through Vijayanagara patronage and Portuguese destruction, and examine the heritage challenges posed by colonial erasure of such sites. 15 marks · 250 words
