GS Paper III 2024 · Q1

10 marks · 150 words Inclusive growth X-Ray · Core #51

Examine the pattern and trend of public expenditure on social services in the post-reforms period in India. To what extent this has been in consonance with achieving the objective of inclusive growth?

Approach · directive: “examine / to what extent”

What it asks · Trace how social-services spending moved after 1991 (level, composition, Centre–State share) and judge whether it has matched the goal of inclusive growth.

It asks 2 things — answer each

  1. Examine the pattern and trend of public expenditure on social services after the 1991 reforms: level, composition and Centre–State shares
  2. To what extent has this been in consonance with inclusive growth: a clear position, qualified by gains and gaps, with a way forward

Open with · Data: social-services spending rose from 6.7% of GDP in 2017-18 to 7.8% in 2023-24 (Economic Survey 2023-24); whether this post-1991 path served inclusive growth is the test.

Cover

  • 1990s: fiscal correction squeezed social budgets; States, which fund most schooling and health, carried the burden.
  • 2000s rights-based turn — SSA, NRHM, MGNREGA (2005), RTE (2009), NFSA (2013) — lifted outlays and widened coverage.
  • Post-2014: JAM and DBT re-targeting, with housing, toilets, piped water and PM-JAY insurance.
  • Level and composition (Economic Survey 2023-24): social services 6.7% of GDP (2017-18) to 7.8% (2023-24); education 2.7%, health 1.9%, below the NHP 2017 goal of 2.5%.
  • Inclusive gains: multidimensional poverty 29.17% (2013-14) to 11.28% (2022-23), about 24.82 crore people (NITI Aayog); near-universal enrolment, sanitation, bank access.
  • Gaps: learning outcomes, out-of-pocket health costs, informal workers' social security and inter-State disparity.
  • Way forward: health spending to the NHP 2017 benchmark, outcome-linked transfers, State delivery capacity.

Close with · Social spending that reaches the bottom quintile in quality, not just coverage, turns growth into the inclusion that Viksit Bharat @2047 presumes.

Model answer· 221words · Minimalist IAS

Public spending on social services rose from 6.7% of GDP in 2017-18 to 7.8% in 2023-24 (Economic Survey 2023-24). Whether the post-1991 path of this spending has served inclusive growth is the test.

Pattern and trend after the reforms

  • 1990s squeeze: fiscal correction after 1991 held social outlays low; States, which fund most schooling and health, carried the burden.
  • Rights-based expansion: SSA, NRHM, MGNREGA (2005), RTE (2009) and NFSA (2013) lifted outlays and widened coverage.
  • Re-targeting since 2014: JAM and direct benefit transfers, with housing, toilets, piped water and PM-JAY hospital insurance.
  • Composition: education 2.7% and health 1.9% of GDP in 2023-24, health still below the National Health Policy 2017 goal of 2.5%.

GS Paper III 2024 · Q2

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

What are the causes of persistent high food inflation in India? Comment on the effectiveness of the monetary policy of the RBI to control this type of inflation.

Approach · directive: “what / comment”

What it asks · List the supply- and demand-side drivers of sticky food prices, then assess how far interest-rate policy can tame inflation that is largely supply-driven.

It asks 2 things — answer each

  1. What: the causes of persistent high food inflation in India — weather, structural, demand and policy drivers
  2. Comment on the effectiveness of RBI's monetary policy against food inflation: limits, value, the current debate and a verdict

Open with · Data: food and beverages carry 45.86% of the CPI basket and food inflation was 7.5% in FY24 (Economic Survey 2023-24), so headline inflation stays sticky even as core eases.

Cover

  • Weather shocks: excessive heat and uneven rainfall hit perishables and pulses (Economic Survey 2023-24); CFPI inflation 7.5% in FY24.
  • Structural: low productivity, fragmented holdings, weak cold chains, post-harvest losses keep supply inelastic.
  • Demand shift: rising incomes move diets towards protein, fruit and vegetables faster than supply adjusts.
  • Policy and global: MSP hikes, import dependence (edible oils, pulses), global prices, abrupt trade curbs.
  • Monetary policy is a demand-side tool: it cannot grow onions; tightening against supply shocks costs growth.
  • Yet it matters: the RBI raised the repo rate 250 bps in 2022-23 to anchor expectations and contain second-round effects; the 4% target with a 2–6% band anchors expectations.
  • Debate: the Economic Survey 2023-24 floated targeting inflation excluding food, with DBT for the poor; the counter-view is that households feel food prices most.
  • Verdict: necessary to contain spillovers, insufficient to tame food prices; supply-side action — stock management, open market operations, trade measures, cold chains, diversification.

Close with · Durable relief lies in supply-side action — stock management, open market operations, trade measures, cold chains and crop diversification — while the RBI guards expectations rather than fighting the weather.

GS Paper III 2024 · Q3

10 marks · 150 words Land reforms

What were the factors responsible for the successful implementation of land reforms in some parts of the country? Elaborate.

Approach · directive: “what / elaborate”

What it asks · Explain why land reforms worked in a few regions (West Bengal, Kerala, Jammu and Kashmir) while they stalled elsewhere.

It asks 2 things — answer each

  1. What: the factors behind successful land reform in some regions (West Bengal, Kerala, Jammu and Kashmir)
  2. Elaborate: explain each factor through the region's experience, contrasting States where reform stalled

Open with · NCERT: land reforms succeeded in Kerala and West Bengal because their governments were committed to land to the tiller; Jammu and Kashmir completes the trio, while elsewhere law passed but land did not change hands.

Cover

  • Political will: Left Front governments in Kerala and West Bengal, the post-1947 regime in J&K (Big Landed Estates Abolition Act 1950, ceiling 22.75 acres).
  • Record of rights: Operation Barga (1978) recorded bargadars in West Bengal, giving security of tenure and a share of produce; 42% of India's beneficiaries.
  • Legal design: Kerala's amended law abolished tenancy and vested ownership in tenants; J&K transferred land to tillers without compensation.
  • Peasant mobilisation: organised tenants and labourers pressed from below and resisted eviction.
  • Administrative drive: settlement camps, panchayat participation and field verification cut manipulation of records.
  • Contrast (NCERT): benami transfers, poor records, 'personal cultivation' loopholes and landlord dominance blunted reform elsewhere.

Close with · The template — commitment, organised beneficiaries and a clean record of rights — can be carried by digitised land records and modern tenancy law to States where inequality in landholding, as NCERT notes, continues to this day.

  1. What: the present world scenario of IPR over life materials — patentability, TRIPS flexibilities, access and benefit-sharing
  2. Explain why India's patents are rarely commercialised despite rising filings

Open with · History: since Diamond v. Chakrabarty (1980) allowed a US patent on a modified bacterium, patents on genes, micro-organisms and plant varieties have spread worldwide and been contested.

Cover

  • TRIPS Article 27.3(b): members may exclude plants and animals other than micro-organisms, but must protect plant varieties by patents or a sui generis system.
  • India: Patents Act Section 3(j) excludes plants, animals and seeds; PPV&FR Act 2001; Biological Diversity Act 2002.
  • Access and benefit-sharing: CBD, Nagoya Protocol; the 2024 WIPO treaty makes disclosure of origin of genetic resources and traditional knowledge mandatory.
  • Filing without a market: 1,03,057 patents granted in 2023-24 (PIB); many academic filings for rankings; WIPO 2024 ranks India sixth in filings, fastest-growing.
  • Weak lab-to-market bridge: few technology-transfer offices, little proof-of-concept or venture funding, thin industry links.

Model answer· 363words · Minimalist IAS

India's labour law grew piecemeal into 29 central statutes, many of colonial vintage. The Second National Commission on Labour (2002) proposed replacing them with a few subject-wise laws; the four Codes of 2019–20 (Wages; Industrial Relations; Social Security; Occupational Safety, Health and Working Conditions) finally did so.

Merits of the four Labour Codes

  • Simplification: one registration, licence and return replace 29 laws, cutting compliance cost and 'inspector raj'.
  • Wage floor for all: a national floor wage below which no worker may be paid extends protection beyond scheduled employments to the unorganised.
  • Gig workers recognised: first statutory social security cover for gig and platform workers, with wider ESIC and EPF reach.
  • Formalisation: appointment letters become mandatory for every worker; fixed-term employees get the same benefits as permanent staff.
  • Flexibility to grow: prior permission for lay-off, retrenchment and closure applies only at 300 or more workers, so firms need not stay small to dodge the law.

UDAN (Ude Desh ka Aam Nagrik), launched in 2016 under the National Civil Aviation Policy, had operated more than 3.44 lakh flights carrying over 163 lakh passengers by March 2026. The demand exists; the case for taking air links deeper rests on geography, economics and security.

Why regional air connectivity needs expanding

  • Geography: hills, the North-East, islands and deserts make surface travel slow; air links tie remote regions to the national economy.
  • Economy: tourism, trade, investment and jobs spread to tier-2 and tier-3 towns, while metro airports decongest as traffic disperses.

Open with · Agriculture uses more than 80% of India's water, yet only about half the net sown area is irrigated (PIB, 2026): a system stretched at the source and wasteful in the field.

Cover

  • Groundwater over-extraction: tubewells dominate; free or cheap power drives falling water tables and salinity in the north-west.
  • Low efficiency: flood irrigation, canal seepage and a gap between irrigation potential created and utilised.

Model answer· 346words · Minimalist IAS

Agriculture uses more than 80% of India's water, yet only about half the net sown area is irrigated (PIB, 2026). The system is stretched at the source and wasteful in the field, and the challenges follow from that paradox.

Major challenges faced by the irrigation system

  • Groundwater over-extraction: tubewells dominate; free or cheap power drives water tables down in Punjab, Haryana and western Uttar Pradesh, and salinity spreads in over-drawn aquifers.
  • Low efficiency: flood irrigation and unlined canals lose much of the water, and a persistent gap separates irrigation potential created from potential utilised.
  • Neglected assets: incomplete projects, silted reservoirs and canals, poor maintenance and water charges too low to fund repair.
  • Crop–water mismatch: paddy and sugarcane in water-scarce regions, encouraged by assured procurement and power subsidies.
  • Climate stress: erratic monsoons, heatwaves and glacial change make rain-fed and canal supply less predictable; inter-State river disputes add uncertainty.
  • Weak governance: fragmented departments, little farmer participation and poor data on actual water use.

Approach · directive: “elucidate / discuss”

What it asks · Explain how buffer stocks steady farm and consumer prices, then discuss storage-related problems.

It asks 2 things — answer each

  1. Elucidate the importance of buffer stocks for stabilising agricultural prices: floor for farmers, ceiling for consumers, food security
  2. Discuss the challenges associated with storing buffer stocks: capacity, losses, cost and institutions

Open with · Buffer stocks are foodgrains held in the central pool beyond immediate needs; on 1 July 2025 stocks stood at 736.61 lakh tonnes against a norm of 411.20 lakh tonnes.

Cover

  • Price floor for farmers: MSP procurement into the central pool prevents distress sales in glut years.
  • Price ceiling for consumers: OMSS(D) sales of surplus wheat and rice, PDS releases, and Bharat Atta and Bharat Rice at subsidised rates.
  • Food security: NFSA and welfare schemes, emergencies and strategic reserves; Price Stabilisation Fund buffers for pulses and onion.
  • Storage challenges: capacity shortfall and reliance on open cover-and-plinth storage; regional mismatch between procurement and consumption.
  • Losses and quality: pests, moisture and ageing grain; perishables like onion need specialised storage.
  • Cost and excess: stocks far above norms lock up capital and inflate FCI's carrying cost; the Shanta Kumar Committee (2015) urged leaner stocks.
  • Way forward: silos, the 700 lakh tonne cooperative grain storage plan, decentralised procurement and warehouse-receipt finance.

Close with · A buffer sized to its norms, stored in silos and PACS godowns and released early through OMSS turns a costly stockpile into a true price stabiliser, the leaner FCI that Shanta Kumar envisaged.

Model answer· 368words · Minimalist IAS

Buffer stocks are foodgrains held in the central pool beyond immediate needs, to meet shortfalls and cool prices. On 1 July 2025 the pool held 736.61 lakh tonnes of rice and wheat against a norm of 411.20 lakh tonnes: proof of both their power and their cost.

Importance for stabilising agricultural prices

  • Floor for farmers: MSP procurement into the central pool absorbs gluts and prevents distress sales, steadying farm incomes.
  • Ceiling for consumers: surplus wheat and rice are sold through the Open Market Sale Scheme (Domestic) to moderate prices; Bharat Atta (November 2023) and Bharat Rice (February 2024) took subsidised grain straight to retail.
  • Food security: NFSA entitlements for about two-thirds of the population, welfare schemes and emergency relief run on the buffer; a strategic reserve insures against drought and global shocks.
  • Beyond grain: the Price Stabilisation Fund holds pulses and onion for release when retail prices spike.

The world is facing an acute shortage of clean and safe freshwater. What are the alternative technologies which can solve this crisis? Briefly discuss any three such technologies citing their key merits and demerits.

Approach · directive: “what / discuss”

What it asks · Name alternative water technologies and evaluate three of them with merits and demerits.

It asks 2 things — answer each

  1. What: the alternative technologies that can address the freshwater crisis
  2. Discuss any three of them with their key merits and demerits

Open with · WHO and UNICEF (2025) report that 1 in 4 people, 2.1 billion, still lack safely managed drinking water, as pollution and climate change shrink the usable supply.

Cover

  • Options: desalination, wastewater recycling, atmospheric water generation, managed aquifer recharge, rainwater harvesting, fog harvesting, solar stills.
  • Desalination (reverse osmosis): drought-proof supply, as at Chennai's Minjur (2010) and Nemmeli (2013) plants; but energy-intensive, costly, and brine harms marine life.
  • Wastewater recycling: Singapore's NEWater turns treated used water into ultra-clean reclaimed water from four plants; needs investment and public acceptance.
  • Atmospheric water generators: draw water from humid air, useful off-grid; high energy use, low output and humidity dependence.
  • Managed aquifer recharge: cheap, stores water underground; depends on geology and clean recharge water.
  • Cross-cutting: pair technology with pricing, leak control and renewable power to keep costs and emissions down.

Close with · No single technology suffices; a portfolio built on reuse and recharge, with desalination as a coastal backstop, is the path to SDG 6.3 on recycling and 6.4 on water-use efficiency.

Disaster resilience, in UNDRR's definition, is the ability of a system, community or society exposed to hazards to 'resist, absorb, accommodate, adapt to, transform and recover' from a hazard's effects in a timely and efficient manner, keeping its essential structures and functions. Resilience is thus a property built before the hazard arrives.

How disaster resilience is determined

  • Risk factors: hazard exposure, physical and social vulnerability (poor housing, poverty, gender, disability) and coping capacity: income, infrastructure, institutions and social capital.
  • System properties: robustness, redundancy, resourcefulness and rapidity.
  • Indicators: risk, preparedness, recovery time and losses avoided, tracked against Sendai's own measures of mortality, people affected, economic loss and infrastructure damage.

  1. Discuss the causes of urban flooding: climate-induced and urban
  2. Mention the features of two major urban floods of the last two decades in India
  3. Describe the policies and frameworks in India that aim to tackle urban floods

Open with · Urban floods differ from riverine floods: intense rain on paved, encroached cities overwhelms drains within hours; after Mumbai 2005, NDMA was the first to treat urban flooding as a separate disaster.

Cover

  • Climate: more frequent extreme rainfall events and cyclonic rain; sea-level rise and tidal backflow in coastal cities.
  • Urban causes: encroached lakes and drains, impervious surfaces, drains that fail for poor maintenance, unplanned growth on floodplains (NDMA).
  • Mumbai (26 July 2005): 944 mm in 24 hours at Santa Cruz, choked Mithi river and drains, over 60% of the city inundated.

Model answer· 368words · Minimalist IAS

Urban floods differ from riverine floods: intense rain on paved, encroached cities overwhelms drains within hours. Hyderabad (2000), Mumbai (2005), Surat (2006) and Kolkata (2007) flooded within one decade, and after Mumbai the NDMA, for the first time, treated urban flooding as a separate disaster.

Causes of this climate-induced disaster

  • Climate-induced: more frequent extreme rainfall and cyclonic rain; sea-level rise and tidal backflow that block drainage in coastal cities.
  • Encroachment: lakes, wetlands and natural drains built over; NDMA calls encroachments 'a major problem in many cities and towns'.
  • Run-off and drains: impervious surfaces raise run-off while drains designed for old rainfall norms fail further for poor maintenance and solid waste choking outfalls.
  • Governance: fragmented agencies, weak zoning enforcement and poor real-time rainfall data.
