GS Paper III 2025 · Q1

10 marks · 150 words Inclusive growth X-Ray · Core #4

Distinguish between the Human Development Index (HDI) and the Inequality-adjusted Human Development Index (IHDI) with special reference to India. Why is the IHDI considered a better indicator of inclusive growth?

Approach · directive: “distinguish / why”

What it asks · Set the HDI against the IHDI in concept and measurement, read India’s numbers through both, and argue why the IHDI better shows whether growth is shared.

It asks 2 things — answer each

  1. Distinguish between the HDI and the IHDI in concept and measurement, with special reference to India's numbers
  2. Explain why the IHDI is considered a better indicator of inclusive growth

Open with · India's HDI is 0.685 (2023, rank 130 of 193), yet inequality cuts it by 30.7% (HDR 2025); that gap is the case for the IHDI.

Cover

  • HDI: geometric mean of life expectancy, schooling (mean and expected years) and GNI per capita — an average that is blind to distribution.
  • IHDI: each dimension is discounted for inequality; it equals the HDI only under perfect equality — the percentage gap is the inequality loss.
  • India (HDR 2025): HDI 0.685, rank 130 of 193; inequality lowers the value by about 30.7%, among the higher losses in the region.
  • Sources of India’s loss: income and wealth concentration, gender gaps (low female labour-force participation), unequal learning outcomes, regional gaps in health.
  • Why IHDI suits inclusive growth: it shows who shares the gains — a rising HDI with a widening loss signals growth that leaves many behind.
  • Policy use: points to targeting — school quality, primary health, jobs for women, lagging States and districts (Aspirational Districts approach).
  • Limits: it does not capture group inequality (caste, gender) directly, depends on survey data, and ignores freedoms; read it with the MPI, GDI and GII.

Close with · Tracking the inequality loss beside the headline HDI is how India measures progress on SDG 10, 'reduce inequality within and among countries', and makes growth shared, not merely averaged.

Model answer· 215words · Minimalist IAS

India's HDI is 0.685 (2023, rank 130 of 193), yet inequality cuts it by 30.7% (HDR 2025, per a Deccan Herald report). That gap is the whole case for the IHDI.

How the HDI and the IHDI differ

  • HDI: a geometric mean of life expectancy, schooling and GNI per capita, blind to distribution.
  • IHDI: each dimension is discounted by its Atkinson inequality measure; it equals the HDI only under perfect equality.
  • Loss: the percentage gap between them is the 'loss due to inequality'.

GS Paper III 2025 · Q2

10 marks · 150 words Economy: planning, growth & employment

What are the challenges before the Indian economy when the world is moving away from free trade and multilateralism to protectionism and bilateralism? How can these challenges be met?

Approach · directive: “what / how”

What it asks · Identify how tariff wars, weakened WTO rules and power-based bilateral bargaining hurt India’s exports, investment and policy space — then give a practical response.

It asks 2 things — answer each

  1. Identify the challenges to the Indian economy as the world shifts from free trade and multilateralism to protectionism and bilateralism
  2. Explain how these challenges can be met — abroad and at home

Open with · India's exports hit a record USD 824.9 billion in 2024-25 (RBI), yet with the WTO Appellate Body defunct since December 2019 and tariffs rising, trade now runs on bargaining power, not common rules.

Cover

  • Export shocks: tariffs on labour-intensive goods (textiles, gems, leather, shrimp) hurt MSMEs and jobs; steep US tariffs in 2025 showed the exposure.
  • Weaker rules: without effective WTO dispute settlement, developing economies negotiate one-on-one with larger powers, reducing India’s leverage.
  • Value-chain shifts: reshoring, ‘friend-shoring’, green subsidies and carbon border taxes (EU CBAM on steel, aluminium) can bypass or penalise Indian producers.
  • Bilateral pressure: demands on agriculture, dairy, data flows, IPR and government procurement touch farmers’ livelihoods and policy space.
  • Macro risks: slower global demand, volatile capital flows and rupee pressure; curbs on services trade and mobility of professionals.
  • Response abroad: well-negotiated deals on India’s terms (UAE CEPA, Australia ECTA, EFTA TEPA, UK CETA), market diversification, a WTO-reform coalition with the Global South.
  • Response at home: logistics (PM Gati Shakti), PLI and lower input tariffs, ease of doing business, export credit for MSMEs, and stronger domestic demand.

Close with · Fragmentation is also an opening: selective deals, competitiveness at home and steady advocacy of a rules-based system can carry India to the Foreign Trade Policy 2023 goal of USD 2 trillion exports by 2030.

India's exports hit a record USD 824.9 billion in 2024-25 (RBI), yet with the WTO Appellate Body defunct since December 2019 and tariffs rising, trade now runs on bargaining power, not common rules.

Challenges before the Indian economy

  • Export shocks: tariffs on labour-intensive exports (textiles, gems, leather, shrimp) hit MSMEs and jobs, as the steep US tariffs of 2025 showed.
  • Weaker rules: without dispute settlement, India bargains one-to-one with larger economies and loses the leverage rules gave smaller players.
  • Value-chain shifts: reshoring, 'friend-shoring', green subsidies and the EU's CBAM on steel and aluminium penalise Indian producers.
  • Bilateral pressure: demands on agriculture, dairy, data flows, IPR and procurement squeeze farmers and policy space.

GS Paper III 2025 · Q3

10 marks · 150 words Crops, irrigation & farm marketing X-Ray · Core #8

Explain the factors influencing the decision of the farmers on the selection of high value crops in India.

Approach · directive: “explain”

What it asks · Explain the market, resource, risk and institutional factors that decide whether Indian farmers move from staples to fruits, vegetables, spices, flowers and similar crops.

Open with · Horticulture output reached 3707.38 lakh tonnes from 301.36 lakh hectares in 2024-25: farmers do move to high-value crops when conditions allow, but the choice turns on far more than price.

Cover

  • Market pull: rising incomes, urbanisation and diet diversification; nearness to cities, highways and export channels (Nashik grapes, Jalgaon bananas) favours adoption.
  • Price signals: assured MSP and procurement for wheat and paddy keep farmers in staples; most high-value crops have no price floor.
  • Risk and perishability: price crashes (onion, tomato), pests and weather; weak cold chains and thin insurance deter small farmers.
  • Resources: assured irrigation and micro-irrigation, soil and agro-climate (apples in hills, spices in the Western Ghats), availability of labour.
  • Capital and knowledge: higher input costs and working capital, access to credit, quality planting material and extension advice.
  • Institutions: FPOs, contract farming, e-NAM, processing units and export clusters lower transaction costs; MIDH supports area expansion.
  • Farm size and tenure: marginal farmers with household food-security concerns prefer staples; tenants avoid long-gestation orchards.

Close with · Already the world's second-largest producer of fruits and vegetables (NCERT, 2020), India turns volume into farm income only when diversification is de-risked through cold chains, FPO aggregation, price stabilisation and insurance.

GS Paper III 2025 · Q4

10 marks · 150 words Food processing X-Ray · Core #35

Elaborate the scope and significance of supply chain management of agricultural commodities in India.

Approach · directive: “elaborate”

What it asks · Set out what agricultural supply-chain management covers from farm gate to consumer, and why it matters for farmers, consumers, food security and exports.

It asks 2 things — answer each

  1. Elaborate the scope of supply chain management of agricultural commodities — every link from farm gate to consumer
  2. Elaborate its significance for farmers, consumers, food security and exports

Open with · Agricultural supply chain management links production, aggregation, storage, processing, transport and retail so produce reaches consumers with the least loss and the most value for farmers; India loses 6.02–15.05% of fruits and 4.87–11.61% of vegetables after harvest, mainly in handling, storage and transport (NABCONS, 2020–22).

Cover

  • Scope before harvest: input supply, crop planning linked to demand, contract farming, aggregation through FPOs.
  • Scope after harvest: grading, packaging, warehousing, cold chains, reefer transport, processing, e-NAM trading, retail and export logistics.
  • Farmers: better price realisation and a larger share of the consumer rupee as intermediary layers shrink.
  • Loss reduction: the NABCONS study (reference years 2020–22) estimated losses of 6.02–15.05% for fruits and 4.87–11.61% for vegetables.
  • Food security and prices: buffer-stock and PDS logistics; smoothing tomato–onion–potato price spikes (Operation Greens).
  • Value addition and exports: traceability, quality standards and processing linkages create rural jobs and export earnings.
  • Gaps: fragmented holdings, cold storage concentrated in few States, APMC distortions. Fixes: PM Kisan SAMPADA, Agriculture Infrastructure Fund, warehouse receipts, digital agri-stack.

Close with · A farm-to-fork chain of FPOs, cold chains and digital markets raises farm incomes while cutting waste and food inflation, serving SDG 2: end hunger and promote sustainable agriculture.

10 marks · 150 words Indian achievements in S&T X-Ray · Core #14

The fusion energy programme in India has steadily evolved over the past few decades. Mention India’s contributions to the international fusion energy project – International Thermonuclear Experimental Reactor (ITER). What will be the implications of the success of this project for the future of global energy?

Approach · directive: “mention / what”

What it asks · Trace India’s fusion research, list what India contributes to ITER, and assess what ITER’s success would mean for global energy.

It asks 2 things — answer each

  1. Mention India's contributions to ITER, with the evolution of India's own fusion programme as context
  2. Explain the implications of ITER's success for the future of global energy

Open with · India's fusion programme has grown from the ADITYA tokamak (1989) at the Institute for Plasma Research, Gandhinagar, to the superconducting SST-1 and full ITER membership since 2005.

Cover

  • Evolution: ADITYA tokamak (1989) and its upgrade; SST-1, a steady-state superconducting tokamak; a roadmap towards an indigenous fusion reactor.
  • Membership: one of seven ITER members (EU, China, India, Japan, Korea, Russia, USA); India bears about 9% of construction cost, mostly as hardware.
  • In-kind hardware: the cryostat, in-wall shield blocks, cooling-water system, cryolines and cryo-distribution, RF heating sources, power supplies, diagnostics.
  • Spin-offs: Indian industry, including many MSMEs, gains skills in precision fabrication, cryogenics, superconducting magnets and high-power electronics.
  • Global energy: near-limitless fuel (deuterium from seawater, tritium bred from lithium), no CO2, no long-lived high-level waste, no runaway chain reaction.
  • Geopolitics: less fossil-fuel dependence and import vulnerability; shared intellectual property gives members like India access to the technology.
  • Caveats: repeated delays and cost overruns, tritium supply, materials under neutron load; commercial fusion power is likely decades away.

Close with · ITER's success would turn fusion from physics experiment into an engineering route to clean baseload power; India, co-builder of its cryostat, could add it to the Nuclear Energy Mission for Viksit Bharat target of 100 GW by 2047.

What is Carbon Capture, Utilization and Storage (CCUS)? What is the potential role of CCUS in tackling climate change?

Approach · directive: “what”

What it asks · Define CCUS and its three links, then weigh its potential and limits in climate mitigation, especially for India’s hard-to-abate industries.

It asks 2 things — answer each

  1. Define CCUS — its capture, utilisation and storage links
  2. Explain the potential role of CCUS in tackling climate change, with its limits

Open with · CCUS captures CO2 from power, steel and cement plants, then uses it in products or stores it underground; for an economy pledged to net zero by 2070 with a 45% cut in emissions intensity by 2030 (updated NDC, 2022), it bridges emissions renewables cannot reach.

Cover

  • Capture: pre-combustion, post-combustion (solvents), oxy-fuel; direct air capture and bioenergy with CCS can even give net-negative emissions.
  • Utilisation: urea, methanol, synthetic fuels, polymers, building materials, enhanced oil recovery. Storage: saline aquifers, depleted oil and gas fields, basalt.
  • Climate role: cuts emissions in hard-to-abate sectors — cement process emissions, steel, fertilisers, refineries — where renewables alone cannot.
  • For India: coal will stay in the energy mix for decades; CCUS lets India use it while moving towards net zero by 2070.
  • Co-benefits: a circular carbon economy, new industries and jobs, and lower import bills when CO2 becomes feedstock.
  • Limits: high cost and energy penalty, leakage risk and monitoring, no CO2 pipelines, low carbon price; risk of prolonging fossil lock-in.
  • Enablers: carbon credit trading scheme, hub-and-cluster model in industrial belts, mapping of storage sites, public funding for early projects.

Close with · CCUS complements renewables and efficiency; proven safe and cheaper, it handles the residual industrial emissions on the road to 2070 and to SDG 13, urgent action to combat climate change and its impacts.

Seawater intrusion in the coastal aquifers is a major concern in India. What are the causes of seawater intrusion and the remedial measures to combat this hazard?

Approach · directive: “what”

What it asks · Explain why and how seawater moves into India’s coastal aquifers, and suggest engineering, management and regulatory remedies.

It asks 2 things — answer each

  1. Explain the causes of seawater intrusion into India's coastal aquifers
  2. Suggest remedial measures — engineering, demand management, nature-based and regulatory — to combat the hazard

Open with · Seawater intrusion is the landward movement of saline water into freshwater aquifers when groundwater's seaward flow weakens; at Minjur near Chennai, heavy pumping since the 1970s reversed the hydraulic gradient and let the sea in (CGWB).

Cover

  • Over-pumping for irrigation, industry and cities lowers the water table and reverses the hydraulic gradient (Saurashtra coast, Minjur near Chennai, Vasai–Virar).
  • Reduced recharge: paved urban surfaces, erratic monsoon, and dams that cut river flows to deltas.
  • Sea-level rise, storm surges and cyclones flood low-lying coasts; tides push saline water up creeks and estuaries.
  • Land use: aquaculture ponds, salt pans, sand mining, dredging and loss of mangroves and dunes.
  • Impacts: saline drinking water, soil salinity and falling yields, health stress and out-migration from coastal villages.
  • Engineering remedies: tidal regulators and bandharas, check dams, recharge wells, subsurface barriers, managed aquifer recharge.
  • Management: regulate extraction (CGWA), aquifer mapping, micro-irrigation, mangrove and dune restoration, a coastal monitoring-well network.

Close with · Managing coastal aquifers as a recharged commons — balancing extraction with recharge and restoring natural buffers — secures SDG 6, availability and sustainable management of water and sanitation for all.

Seawater intrusion is the landward movement of saline water into freshwater aquifers when groundwater's seaward flow weakens. At Minjur near Chennai, heavy pumping since the 1970s reversed the hydraulic gradient and let the sea in (CGWB).

Causes of seawater intrusion

  • Over-pumping: irrigation, industry and city wells lower the water table and reverse the gradient.
  • Reduced recharge: paved surfaces, erratic monsoons and dams cutting river flows to deltas.
  • Sea and tides: sea-level rise, surges and cyclones flood low coasts; tidal canals and salt pans push salt inland.
  • Land use and geology: aquaculture ponds, sand mining and lost mangroves; porous formations and coastal depressions worsen it in Saurashtra (CGWB).

The Government of India recently stated that Left Wing Extremism (LWE) will be eliminated by 2026. What do you understand by LWE and how are the people affected by it? What measures have been taken by the government to eliminate LWE?

Approach · directive: “what / how”

What it asks · Define LWE, show its human and developmental cost, and review the security-plus-development strategy the government has used to end it.

It asks 2 things — answer each

  1. Explain what LWE is and how people are affected by it
  2. Explain the measures taken by the government to eliminate LWE — security, development and rights

Open with · Left Wing Extremism is the Maoist armed movement, traced to the 1967 Naxalbari uprising, that seeks to overthrow the State by force, feeding on grievances over land, forests and exclusion.

Cover

  • Meaning: CPI (Maoist)-led insurgency concentrated in forested tribal belts of Chhattisgarh, Jharkhand, Odisha, Maharashtra and Telangana — the ‘Red Corridor’.
  • Effect on people: killings of civilians branded ‘informers’, IEDs, extortion; destruction of schools, roads and mobile towers; displacement.
  • Development deficit: welfare, health and education blocked; tribal communities caught between insurgents and security forces.
  • Security measures: National Policy and Action Plan (2015), SAMADHAN doctrine, CAPF and CoBRA deployment, DRG, fortified police stations, technology-led operations.
  • Development measures: Special Central Assistance, roads and mobile towers in affected areas, Eklavya schools, bank branches, skill centres.
  • Trust and rights: Forest Rights Act, PESA, surrender-cum-rehabilitation policies, choking of funding by investigating agencies.
  • Outcome: affected districts fell steadily, and by August 2026 the government reported no district as LWE-affected; the task now is consolidation.

What it asks · Explain how NITI Aayog’s FHI measures State finances and how its rankings can push States towards prudent, sustainable fiscal policy.

It asks 2 things — answer each

  1. Explain how the Fiscal Health Index can be used as a tool for assessing the fiscal performance of States
  2. Explain in what way it would encourage States to adopt prudent and sustainable fiscal policies

Open with · NITI Aayog's Fiscal Health Index (January 2025) scores 18 major States on five sub-indices; Odisha topped it with 67.8, ahead of Chhattisgarh and Goa, at a time when States' outstanding liabilities (28.5% of GDP, end-March 2024) still exceed the pre-pandemic level.

Cover

  • Design: quality of expenditure, revenue mobilisation, fiscal prudence, debt index and debt sustainability — capturing both annual flows and accumulated debt.
  • Diagnosis: shows each State’s weak spot — high committed spending, low own-tax effort, rising debt — so reform can be targeted.
  • Benchmarking: the 2025 edition ranked Odisha first (67.8), followed by Chhattisgarh and Goa; a second edition followed in 2026.
  • Peer pressure: public rankings build competitive federalism and reputational incentives; lenders and rating agencies read the signal.
  • Policy leverage: can inform Finance Commission and Union decisions on performance-linked grants and extra borrowing limits tied to reforms.
  • Nudges: capital expenditure over populist transfers, better tax and non-tax collection, disclosure of off-budget borrowings and contingent liabilities.
  • Limits: data lags, uniform weights, special-category constraints and dependence on Union transfers; it must not become a tool to squeeze welfare.

Close with · Used as a mirror, the FHI can anchor the RBI's call for a transparent, time-bound glide path for debt consolidation at the tier of government that spends most of India's public money, making State fiscal prudence a shared pillar of Viksit Bharat @2047.

NITI Aayog's Fiscal Health Index (January 2025) scores 18 major States on five sub-indices; Odisha topped it with 67.8, ahead of Chhattisgarh (55.2) and Goa (53.6). It arrives when States' outstanding liabilities, 28.5% of GDP at end-March 2024, still exceed the pre-pandemic 25.3% (RBI, State Finances 2024-25).

How the FHI assesses the fiscal performance of States

  • Five sub-indices: quality of expenditure, revenue mobilisation, fiscal prudence, debt index and debt sustainability, so annual flows and the debt stock are both scored.
  • Diagnosis, not just rank: each sub-index exposes a State's weak spot: committed spending on salaries, pensions and interest, low own-tax effort, or debt rising faster than revenue.
  • Common yardstick: the Union, the Finance Commission, lenders and citizens read every State the same way; the 2026 edition ranks the North-Eastern and Himalayan States separately for fairness.
  • Trend tracking: the second edition found most major States' scores moderating in 2023-24, an early warning that a single budget would not show.

Cover

  • Rationale: scale and cost disadvantages against East Asian rivals, heavy import dependence (electronics, APIs, solar modules), need for manufacturing jobs and exports.
  • Rationale: attract global champions amid ‘China plus one’, integrate into value chains, build strategic capacity (batteries, drones, telecom).
  • Achievements: by 31 December 2025, investment above ₹2.16 lakh crore, production and sales above ₹20.41 lakh crore, and 836 approved applications.
  • Sector gains: mobile phones turned India from importer to exporter; bulk-drug capacity in pharma; Indian food brands abroad.
  • Concerns: uneven uptake (slow in textiles, specialty steel, battery cells), low domestic value addition in assembly, gains concentrated in a few large firms, disbursal delays.
  • Improvements: link incentives to value addition and local sourcing, extend to labour-intensive sectors and component makers, faster and simpler disbursal.

Production Linked Incentive schemes, rolled out from 2020 across 14 sectors from large-scale electronics to drones, pay incentives on incremental sales of goods made in India for a fixed period. By 31 December 2025 they had drawn over ₹2.16 lakh crore of investment and ₹20.41 lakh crore of production (PIB, March 2026).

Rationale of the PLI scheme

  • Scale and cost gaps: Indian manufacturing lacked scale and carried high logistics and power costs against East Asian rivals.
  • Import dependence: electronics, bulk drugs and solar modules exposed supply chains; batteries, telecom gear and drones matter for security too.
  • Timing: the post-pandemic 'China plus one' shift opened a window to attract global champions.
  • Output-linked design: paying only on realised incremental sales limits subsidy without output, unlike upfront capital subsidies.

  • Irrigation dominance: most extraction goes to farms; water-intensive paddy and sugarcane in semi-arid Punjab, Haryana and Maharashtra.
  • Perverse incentives: free or flat-rate farm power, MSP procurement tilted to paddy and wheat, cheap borewells.
  • Urban and industrial demand: paved surfaces cut recharge; unregulated extraction by cities and industries.

India is the world's largest user of groundwater. The 2025 Dynamic Ground Water Resources assessment puts the national stage of extraction at 60.63%, yet 730 of 6,762 assessment units (10.8%) are over-exploited. The average hides a crisis in the north-west and the hard-rock peninsula.

Factors responsible for depleting groundwater

  • Irrigation dominance: farms take most of the draft; in Punjab, Haryana and western Uttar Pradesh over 85% of net sown area is irrigated, mainly for wheat and rice (NCERT).
  • Perverse incentives: free or flat-rate farm power, MSP procurement tilted to paddy and wheat, and cheap borewells make over-pumping the rational private choice.
  • Urban and industrial demand: paved surfaces cut recharge while cities and industries extract with little regulation.
  • Hydrogeology and climate: the peninsula's hard-rock aquifers store little; erratic, intense rainfall recharges less.

Model answer· 373words · Minimalist IAS

Semiconductors are the base layer of the digital economy and of defence. India consumes chips at scale and is a global design hub, but fabrication and packaging at home began only with the India Semiconductor Mission (ISM), approved in December 2021 with a ₹76,000 crore incentive framework.

Challenges faced by the semiconductor industry in India

  • Capital and time: a fab costs billions of dollars, takes years and faces fast obsolescence and heavy licensing costs.
  • Ecosystem gaps: ultra-pure water, uninterrupted power, specialty gases and chemicals, and a dense supplier web that India lacks.
  • Skills and IP: strong design talent but few fab-process engineers and little home-grown process IP; talent drains to established hubs.
  • Competition and geopolitics: large subsidies in the US, EU, Japan and Taiwan; export controls on advanced tools; few equipment makers.
  • Thin domestic offtake: assured demand for India-made chips is small, so early value addition sits in packaging, not wafer fabrication.

Approach · directive: “why / explain”

What it asks · Explain the damage mining does to land, water, air, biodiversity and people, and propose remedies across the life of a mine.

It asks 2 things — answer each

  1. Explain why mining is considered an environmental hazard — land, water, air, biodiversity and people
  2. Explain the remedial measures required across the life of a mine to reduce the hazard

Open with · Minerals underpin energy, infrastructure and manufacturing, but mining strips land cover, rock and water from ecosystems and leaves a footprint that outlives the mine; managing that footprint, not avoiding mining, is the policy task.

Cover

  • Land and forests: deforestation, topsoil loss, overburden dumps, subsidence, and fragmented wildlife corridors in central India’s coal and iron-ore belts.
  • Water: acid mine drainage, heavy-metal leaching, falling water tables and silted rivers.
  • Air and health: dust and particulate pollution, underground coal fires (Jharia), silicosis and pneumoconiosis among workers.
  • Social: displacement of tribal communities and loss of forest-based livelihoods, often with poor rehabilitation.
  • Illegal and unscientific mining: riverbed sand mining; abandoned mines left unreclaimed.

Write a review on India’s climate commitments under the Paris Agreement (2015) and mention how these have been further strengthened in COP26 (2021). In this direction, how has the first Nationally Determined Contribution intended by India been updated in 2022?

Approach · directive: “write a review / mention / how”

What it asks · Review India’s Paris pledges and progress, show how COP26 raised ambition, and state exactly what the 2022 updated NDC changed.

It asks 3 things — answer each

  1. Review India's climate commitments under the Paris Agreement (2015), with their progress
  2. Mention how these commitments were strengthened at COP26 (2021)
  3. Explain how India's first NDC was updated in 2022

Open with · The Paris Agreement (2015) lets each country set its own Nationally Determined Contribution; India's first NDC balanced climate action with development and common but differentiated responsibilities, and has since been over-delivered, with emissions intensity down 36% between 2005 and 2020.

Cover

  • 2015 pledge (by 2030): emissions intensity of GDP down 33–35% from 2005; 40% non-fossil power capacity; 2.5–3 billion tonnes CO2e additional carbon sink.
  • Review: the non-fossil capacity and emissions-intensity goals were met well ahead of 2030; the forest-sink goal has progressed more slowly.
  • COP26 ‘Panchamrit’: 500 GW non-fossil capacity, half of energy needs from renewables, one billion tonnes less emissions, 45% intensity cut, net zero by 2070.
  • COP26 also launched LiFE (Lifestyle for Environment) and the Green Grids Initiative — One Sun One World One Grid.
  • 2022 update (by 2030): emissions intensity down 45% from 2005; about 50% of installed power capacity non-fossil; LiFE written into the NDC.
  • Follow-up: long-term low-emission development strategy (COP27), Green Hydrogen Mission, Carbon Credit Trading Scheme, ethanol blending.
  • Gaps: climate finance and technology transfer from developed countries, coal dependence, adaptation needs.

Close with · India's climate record is one of over-delivery; the 2035 NDC now ties it to Viksit Bharat @2047 and net zero by 2070, while rightly insisting that developed countries deliver finance and equity under the Paris Agreement.

  • Three quantified goals for 2030: emissions intensity of GDP down 33–35% from 2005; about 40% of installed power capacity from non-fossil sources; an additional carbon sink of 2.5–3 billion tonnes of CO2 equivalent through forest and tree cover.
  • Qualitative goals: a sustainable way of living rooted in conservation, a cleaner growth path, adaptation, and mobilising finance and technology.
  • Delivered early: the intensity and non-fossil goals were met 11 and 9 years ahead of time (PIB, 2026).
  • Slower front: the forest sink reached 2.29 billion tonnes by 2021, short of the 2.5–3 billion range.

It asks 3 things — answer each

  1. Explain why maritime security is vital to protect India's sea trade
  2. Discuss the maritime and coastal security challenges
  3. Discuss the way forward — institutions, capacity, partnerships and resilience

Open with · Nearly 95% of India's trade by volume and about 70% by value moves by sea (PIB, 2025); the sea lanes of the Indian Ocean are the arteries of the economy, so their security is a national interest, not only a naval task.

Cover

  • Why vital: oil, LNG and container trade pass chokepoints (Hormuz, Bab-el-Mandeb, Malacca); disruption raises freight and insurance costs, as in the Red Sea crisis.
  • Non-traditional threats: piracy off Somalia, attacks on merchant ships, illegal fishing, drug and arms smuggling by sea.
  • Strategic threats: growing extra-regional naval presence, dual-use ports and research vessels in the Indian Ocean, grey-zone tactics.
  • Coastal gaps: long coastline and islands; seaborne infiltration as in 26/11; tracking lakhs of small boats; coordination among Navy, Coast Guard, marine police.
  • Climate and disaster: cyclones, sea-level rise and oil spills threaten ports and coastal communities.
  • Way forward — institutions: coastal radar chain, IFC-IOR at Gurugram, transponders on fishing boats, National Maritime Security Coordinator, stronger marine police.
  • Way forward — capacity and partners: blue-water navy and shipbuilding, deep-water ports, Andaman and Nicobar Command; SAGAR/MAHASAGAR, IORA, Quad, Colombo Security Conclave.

Model answer· 363words · Minimalist IAS

Nearly 95% of India's trade by volume and about 70% by value moves by sea (PIB, 2025). The sea lanes of the Indian Ocean are the arteries of the economy, so their security is a national interest, not only a naval task.

Why maritime security is vital to protect India's sea trade

  • Energy and trade lifelines: crude, LNG and container traffic pass the chokepoints of Hormuz, Bab-el-Mandeb and Malacca; disruption raises freight and insurance costs, as the Red Sea crisis showed.
  • Ports and the blue economy: Sagarmala's 840 projects worth ₹5.8 lakh crore to 2035 and the ₹25,000 crore Maritime Development Fund all presume secure waters.
  • Strategic weight: a secure Indian Ocean underpins India's role as a net security provider and its Indo-Pacific partnerships.
