GS III Q1Economy

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?

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Examine Probe the issue in depth: Causes, evidence and consequences.
  • To what extent Answer with a measured extent, backed by evidence on both sides.

For Economy: Use current data and scheme names; a simple flowchart of cause and effect works well.

For this question: Describe the trend, then judge inclusiveness with gains and gaps; the FY22 to FY26 growth anchors it.

What the question asks

Examine the pattern and trend of public spending on social services since the 1991 reforms, and judge how far it has served the aim of inclusive growth.

A strong opening

Social services cover education, health, family welfare, water supply and sanitation, housing, urban development, the welfare of SCs, STs and OBCs, labour welfare, social security, nutrition and disaster relief. Most of this spending is done by the States.

Points to cover

Pattern and trend

  • In the early 1990s fiscal correction squeezed social spending; from the mid-2000s rights-based programmes (education, rural employment, food security, health missions) raised it.
  • Recent years: The general government's social services expenditure has risen since FY22, growing at a compound annual rate of 12 per cent from FY22 to FY26 (BE); education grew at 11 per cent and health at 8 per cent a year.
  • Its share of total government expenditure fell to 23.3 per cent in FY21 and rose to 26.6 per cent in FY26 (BE).
  • A shift in form: More direct benefit transfers, insurance-based health care and centrally sponsored schemes.

How far it has served inclusive growth

  • Gains: Near-universal school enrolment, falling multidimensional poverty, and the Household Consumption Expenditure Survey 2023-24 showing the fastest growth in spending among the bottom 5 to 10 per cent.
  • Gaps: Spending on health and education remains low by international standards, learning outcomes are weak, regional inequality is wide, and much spending goes to subsidies rather than human capital.

Way forward

  • Raise health and education spending, untie funds for States, focus on outcomes (learning, nutrition) and strengthen local delivery.
A balanced conclusion

Social spending has grown and broadened since the reforms, and poverty has fallen. Growth becomes truly inclusive only when that spending buys better schools, health and skills.

GS III Q2Economy

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.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Comment Give your opinion on the statement, backed by reasons and evidence.

For Economy: Use current data and scheme names; a simple flowchart of cause and effect works well.

For this question: Separate supply-side causes from what monetary policy can do; conclude that it contains, not cures.

What the question asks

Identify why food inflation in India stays high, and comment on how effective RBI's monetary policy is against this kind of inflation.

A strong opening

Food has a large weight in India's Consumer Price Index, so food prices drive headline inflation. Most food price spikes come from the supply side, while monetary policy works mainly on demand.

Points to cover

Causes of persistent food inflation

  • Supply shocks: Drought, erratic or failed monsoons, heatwaves and floods damage crops, especially vegetables and pulses.
  • Structural: Low productivity, small holdings, weak storage and cold chains, and many intermediaries between farm and market.
  • Rising costs: Higher agricultural wages, fuel and fertiliser prices, and international food prices.
  • Demand: Rising incomes shift diets towards protein, milk, fruit and vegetables, whose supply grows more slowly.
  • Policy: Rising minimum support prices and occasional trade restrictions.

RBI's monetary policy

  • The Monetary Policy Committee (six members, three from RBI and three nominated by the government) sets the policy rate to hold inflation at 4 per cent within a band of 2 to 6 per cent; the target was renewed on 25 March 2026 for five more years, to March 2031.
  • Higher interest rates cool demand and anchor inflation expectations, which stops food price rises from spreading to wages and other prices.

How effective it is

  • Limited against the first-round effect: Interest rates cannot make it rain or reduce onion prices.
  • Useful against second-round effects: Keeping expectations anchored prevents a supply shock from becoming general inflation.
  • Over-tightening to fight a food shock can hurt growth; so supply-side measures (storage, trade policy, buffer stocks, crop diversification) are the main tools.
A balanced conclusion

Food inflation is mainly a supply problem, which monetary policy cannot cure but can contain. Lasting control needs farm productivity, storage and better markets alongside an anchored inflation target.

GS III Q3Agriculture

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

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Elaborate Develop each point in detail, with an example for each.

For Agriculture: Name missions and schemes, give one figure, and link to farmer income and food security.

For this question: Name the factors, then show them at work in Operation Barga with its figure of bargadars recorded.

What the question asks

Explain the factors that made land reforms succeed in some parts of India, with examples.

A strong opening

Land reforms after Independence aimed to abolish intermediaries, protect tenants, fix ceilings on holdings and redistribute surplus land. Zamindari abolition succeeded broadly, but tenancy and ceiling reforms succeeded only in a few States, notably West Bengal and Kerala.

Points to cover

Factors behind success

  • Political will: Governments with a strong rural poor base pushed the reforms (the Left Front in West Bengal, successive governments in Kerala).
  • Mobilisation and organisation: Peasant unions and panchayats helped identify tenants and resist evictions.
  • Recording rights: Accurate land records gave tenants legal proof of their claims.
  • Administrative drive: Camps in villages, officials going to the field, and quick settlement of disputes.
  • Legal backing: Laws that protected tenants from eviction and fixed their share of the produce.

West Bengal: Operation Barga

  • Launched in 1978 and given legal backing in 1979 and 1980, it recorded sharecroppers (bargadars), protecting them against eviction by landlords (jotedars) and entitling them to a due share of the produce.
  • About 1.5 million bargadars were recorded.

Where reforms failed

  • Benami and fictitious transfers, oral tenancies, weak records, landlord influence in politics and courts, and lack of will.
A balanced conclusion

Land reforms succeeded where political will met organised beneficiaries and good land records. The lesson for today is that records and mobilisation matter as much as laws.

GS III Q4Agriculture

Explain the role of millets for ensuring health and nutritional security in India.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Explain Say what it is and why or how it happens, step by step.

For Agriculture: Name missions and schemes, give one figure, and link to farmer income and food security.

For this question: Give nutrition, then resilience, with the finger millet calcium figure as the striking fact.

What the question asks

Explain how millets can help ensure health and nutritional security in India.

A strong opening

Millets are small-grained cereals such as sorghum (jowar), pearl millet (bajra), finger millet (ragi), foxtail, kodo, little and barnyard millets. India proposed, and the UN declared, 2023 as the International Year of Millets.

Points to cover

Nutritional value

  • Millets are high in protein, fibre, calcium, iron and zinc; finger millet contains about 344 mg of calcium per 100 g, far more than other grains.
  • They are gluten-free, so they suit people with coeliac disease or gluten sensitivity.
  • Their fibre and slower digestion help in managing diabetes and lifestyle diseases.

Role in nutritional security

  • Can address hidden hunger (micronutrient deficiency) and anaemia among women and children.
  • Inclusion in the public distribution system, school meals and anganwadi nutrition widens access.

Role in food security and resilience

  • Highly tolerant of drought and extreme weather, they grow in rainfed and poor soils with little water and fertiliser.
  • India produces about 20 per cent of the world's millets and 80 per cent of Asia's.

Challenges

  • Low demand and taste preferences, weak processing and shelf life, lower procurement and MSP support than rice and wheat.
A balanced conclusion

Millets combine nutrition with climate resilience. Bringing them back into everyday diets needs procurement, processing and public awareness together.

GS III Q5Science and Technology

What is the present world scenario of intellectual property rights with respect to life materials? Although, India is second in the world to file patents, still only a few have been commercialized. Explain the reasons behind this less commercialization.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Explain Say what it is and why or how it happens, step by step.

For Science and Technology: Explain how it works (a small diagram), then applications for India and concerns.

For this question: Explain TRIPS Article 27.3(b) first, then India's position, then the commercialisation gap.

What the question asks

Describe the present world scenario of intellectual property rights over life forms, then explain why few of India's patents are commercialised.

A strong opening

Patents on living material (genes, micro-organisms, plant varieties, biotechnological processes) are governed internationally by the WTO's TRIPS Agreement and the Convention on Biological Diversity, and nationally by each country's law.

Points to cover

The world scenario

  • TRIPS requires patents in all fields of technology for at least 20 years, but Article 27.3(b) lets members exclude plants and animals, while requiring protection for micro-organisms and microbiological processes and protection of plant varieties by patents or an effective sui generis system.
  • The US and some others allow patents on genetically modified organisms and isolated genetic material; many developing countries resist, citing biopiracy and access to medicines.
  • The Convention on Biological Diversity and the Nagoya Protocol require prior informed consent and benefit-sharing for genetic resources and traditional knowledge.

India's position

  • The Patents Act excludes plants and animals and essentially biological processes; plant varieties are protected under the Protection of Plant Varieties and Farmers' Rights Act, 2001.
  • Section 3(d) bars patents on new forms of known substances unless they differ significantly in efficacy; the Supreme Court upheld it in Novartis v. Union of India (2013), refusing a patent for Glivec.

Why few patents are commercialised

  • Weak links between universities, laboratories and industry; few technology transfer offices.
  • Low private research spending and limited venture capital for long, risky development.
  • Many patents are filed for academic credit, not for market use; poor market assessment.
  • Long patent examination and litigation, and small firms' lack of capacity to license or scale up.
A balanced conclusion

Global IPR on life forms balances innovation against access and biodiversity rights, and India has chosen a careful middle path. Turning patents into products needs stronger industry-academia links and risk capital.

GS III Q6Science and Technology

What is the technology being employed for electronic toll collection on highways? What are its advantages and limitations? What are the proposed changes that will make this process seamless? Would this transition carry any potential hazards?

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Explain Say what it is and why or how it happens, step by step.

For Science and Technology: Explain how it works (a small diagram), then applications for India and concerns.

For this question: Answer all four parts in order: Technology, pros and cons, GNSS change, and its hazards.

What the question asks

Explain the technology used for electronic toll collection on India's highways, its advantages and limitations, the proposed changes for seamless tolling, and the risks of that transition.

A strong opening

India collects highway tolls electronically through FASTag, which uses Radio Frequency Identification (RFID): A tag on the windscreen is read at the toll plaza and the toll is deducted from the linked account.

Points to cover

FASTag: How it developed

  • Rolled out on national highways from 2016, made mandatory on new vehicles from December 2017, and mandatory on all national highways from 15 December 2019 (fully from 15 February 2021), with double toll for vehicles without it.
  • An annual pass option allows a fixed fee for a set number of toll crossings.

Advantages and limitations

  • Advantages: Shorter waiting time, less fuel wasted, digital records, less cash handling and leakage.
  • Limitations: Tag reading failures, low balance and blacklisting, tag misuse, and the toll plaza itself as a bottleneck; payment is per plaza, not per kilometre travelled.

Proposed changes: GNSS-based tolling

  • Global Navigation Satellite System (GNSS) tolling is a barrier-free method in which road users are charged for the distance they travel on the tolled highway.
  • An On-Board Unit in the vehicle sends location and time pings to a central toll charger, which calculates the distance and the fee; existing plazas get dedicated GNSS lanes with barriers open by default.
  • Automatic number plate recognition (ANPR) cameras support enforcement in a multi-lane free-flow system.

Potential hazards

  • Privacy: Continuous location tracking of vehicles; data security and misuse.
  • Technical: Signal loss in tunnels, hills and cities; errors on parallel service roads and flyovers.
  • Enforcement and equity: Evasion, wrong penalties, and the cost of devices for small operators.
A balanced conclusion

Moving from plaza-based FASTag to distance-based GNSS tolling can make travel seamless and fairer. It must come with strong data protection and reliable enforcement.

GS III Q7Environment

Industrial pollution of river water is a significant environmental issue in India. Discuss the various mitigation measures to deal with this problem and also the government’s initiatives in this regard.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Discuss Cover the main aspects, with arguments on more than one side.

For Environment: Name the convention or law and its targets, with an Indian example.

For this question: Keep two blocks, mitigation measures and government initiatives, with Namami Gange in the second.

What the question asks

Discuss measures to reduce industrial pollution of river water in India and the government's initiatives against it.

A strong opening

Industries such as tanneries, distilleries, sugar mills, pulp and paper, chemicals and textiles discharge effluents with heavy metals, organic waste and toxic chemicals into rivers, alongside untreated city sewage.

Points to cover

Mitigation measures

  • Treatment at source: Effluent treatment plants in each unit, and Common Effluent Treatment Plants for clusters of small industries.
  • Zero liquid discharge for highly polluting industries, recycling treated water.
  • Cleaner production: Less water-intensive and less toxic processes; recovery of chromium, fibre and other materials.
  • Real-time online effluent monitoring, with data shared with pollution control boards.
  • The polluter pays principle: Penalties and closure of units that violate standards.

Government initiatives

  • The Water (Prevention and Control of Pollution) Act, 1974 set up the Central and State Pollution Control Boards; the Environment (Protection) Act, 1986 sets discharge standards.
  • Namami Gange, announced in 2014 with an initial budget of Rs 20,000 crore, covers sewage treatment, riverfront development, river surface cleaning, biodiversity and industrial monitoring; it is run by the National Mission for Clean Ganga under the National Ganga Council chaired by the Prime Minister.
  • The National River Conservation Plan for other rivers, and directions of the National Green Tribunal.

Gaps

  • Weak enforcement and understaffed boards, small units unable to afford treatment, and slow completion of treatment projects.
A balanced conclusion

Industrial river pollution can be controlled with treatment at source, strict monitoring and cleaner technology. Enforcement, more than new law, is the missing piece.

GS III Q8Environment

What role do environmental NGOs and activists play in influencing Environmental Impact Assessment (EIA) outcomes for major projects in India? Cite four examples with all important details.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Cite Give specific, named examples with their key details.

For Environment: Name the convention or law and its targets, with an Indian example.

For this question: Give four examples with place, project, actors and outcome, as the question demands details.

What the question asks

Explain how environmental NGOs and activists influence the outcomes of Environmental Impact Assessment (EIA) for major projects in India, and give four detailed examples.

A strong opening

EIA studies a project's likely effects on the environment and people before it is approved. Under the EIA Notification, 2006 under the Environment (Protection) Act, 1986, most large projects need prior environmental clearance, including a public hearing for affected people.

Points to cover

How NGOs and activists influence EIA

  • Public hearings: They help affected people raise objections, often in local languages.
  • Independent studies: They expose gaps or errors in the project's EIA report.
  • Litigation: Petitions before the National Green Tribunal, High Courts and the Supreme Court.
  • Campaigns and media: Building public opinion and drawing in scientists and policymakers.

Example 1: Silent Valley (Kerala)

  • A campaign started by the Kerala Sasthra Sahithya Parishad opposed a hydroelectric project that would flood the valley; scientists such as Salim Ali appealed against it.
  • The project was dropped and the valley was declared Silent Valley National Park in 1985.

Example 2: Narmada Bachao Andolan

  • Founded by Medha Patkar in 1985, it organised adivasis, farmers and environmentalists against large dams on the Narmada, especially the Sardar Sarovar Dam in Gujarat.
  • It forced attention to resettlement and rehabilitation of displaced people; the movement received the Right Livelihood Award in 1991.

Example 3: Niyamgiri (Odisha)

  • Activists and the Dongria Kondh tribe opposed bauxite mining for Vedanta's refinery in the Niyamgiri hills.
  • The Ministry of Environment and Forests scrapped the forest clearance; in Orissa Mining Corporation v. Ministry of Environment and Forest (18 April 2013) the Supreme Court gave gram sabhas a role in safeguarding tribal rights under the Forest Rights Act, and every village council then rejected the project.

Example 4: Sterlite copper smelter (Thoothukudi)

  • Local residents and activists campaigned for years against pollution by the smelter; NEERI and the Tamil Nadu Pollution Control Board found contamination of groundwater, air and soil.
  • In 2013 the Supreme Court fined Sterlite Rs 100 crore; after protests the Tamil Nadu government shut the plant on 28 May 2018.
A balanced conclusion

NGOs and activists make EIA a real public process rather than a formality. Their role is most constructive when backed by evidence and the voices of affected communities.

GS III Q9Internal Security

Explain how narco-terrorism has emerged as a serious threat across the country. Suggest suitable measures to counter narco-terrorism.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Explain Say what it is and why or how it happens, step by step.
  • Suggest End with practical, specific measures, not general wishes.

For Internal Security: Name laws, agencies and a recent case; balance security with rights.

For this question: A sketch map of the Golden Crescent and Golden Triangle around India shows the threat at once.

What the question asks

Explain how narco-terrorism has become a serious threat across India, and suggest measures to counter it.

A strong opening

Narco-terrorism is the use of drug trafficking to fund, support or carry out terrorism. India lies between two of the world's main opium-producing regions: The Golden Crescent (Afghanistan, Pakistan, Iran) to the west and the Golden Triangle (Myanmar, Laos, Thailand) to the east.

Points to cover

How it has emerged as a threat

  • Funding: Drug money finances terrorist and insurgent groups in Jammu and Kashmir, Punjab and the North-East.
  • Cross-border routes: Drugs and weapons come across the Pakistan border (including by drones) and through porous borders with Myanmar; sea routes bring large consignments to western ports.
  • Social damage: Addiction among youth, especially in Punjab, weakens communities and creates recruits for crime.
  • Nexus: Smugglers, gangsters, hawala operators and terror groups work together; synthetic drugs and the dark web make detection harder.

Legal and institutional framework

  • The Narcotic Drugs and Psychotropic Substances Act, 1985 provides stringent penalties and forfeiture of drug-trafficking property.
  • The Narcotics Control Bureau, set up in March 1986, is the apex agency for coordinating drug law enforcement.

Measures to counter it

  • Border security: Anti-drone systems, fencing, technology and coordination along the western and eastern borders.
  • Financial intelligence: Tracking hawala and drug money; seizing assets.
  • Coordination among the NCB, NIA, State police and coastal agencies; shared databases.
  • Demand reduction: De-addiction centres, awareness campaigns and rehabilitation.
  • International cooperation with neighbours and the UN Office on Drugs and Crime.
A balanced conclusion

Narco-terrorism links drugs, crime and terror, so it must be fought on the border, in finance and in society together. Cutting demand at home is as important as stopping supply.

GS III Q10Science and Technology

Describe the context and salient features of the Digital Personal Data Protection Act, 2023.

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Describe Give the main features in an orderly account.

For Science and Technology: Explain how it works (a small diagram), then applications for India and concerns.

For this question: Give context in two lines, then list features: Fiduciaries, consent, children, Board, penalties.

What the question asks

Describe the context and salient features of the Digital Personal Data Protection Act, 2023.

A strong opening

India's digital economy and public digital platforms collect vast amounts of personal data. After the Supreme Court held privacy to be a fundamental right in Puttaswamy (2017), and a committee chaired by Justice B. N. Srikrishna drafted a data protection bill, Parliament passed the Digital Personal Data Protection Act; it received assent on 11 August 2023.

Points to cover

Context

  • No dedicated data protection law existed; data breaches and misuse of personal data were growing concerns.
  • Earlier bills (2018, 2019, 2022) were withdrawn or revised after debate.

Salient features

  • Covers digital personal data processed in India, and processing outside India for offering goods or services to people in India.
  • Data Fiduciaries (those who decide how data is processed) must process data for a lawful purpose with the consent of the Data Principal (the person), or for certain legitimate uses such as employment, legal obligations and emergencies.
  • Rights of Data Principals: Access to information, correction and erasure, grievance redress and nominating another person.
  • Children: Verifiable consent of the parent is needed before processing a child's data.
  • Significant Data Fiduciaries, notified by the government, have extra duties such as a data protection officer and audits.
  • The Data Protection Board of India adjudicates breaches; penalties may extend to Rs 250 crore.

Implementation

  • The Rules were notified on 13 November 2025, with provisions coming into force in phases; the Board's provisions began at once.

Concerns

  • Wide exemptions for government agencies, the government's control over the Board, and amendments to the Right to Information Act regarding personal information.
A balanced conclusion

The Act gives India its first comprehensive data protection law built on consent and accountability. Its credibility will rest on an independent Board and narrow State exemptions.

GS III Q11Economy

Discuss the merits and demerits of the four ‘Labour Codes’ in the context of labour market reforms in India. What has been the progress so far in this regard?

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Discuss Cover the main aspects, with arguments on more than one side.

For Economy: Use current data and scheme names; a simple flowchart of cause and effect works well.

For this question: Name all four codes, weigh merits and demerits, then state the progress: In force from 21 November 2025.

What the question asks

Discuss the merits and demerits of the four Labour Codes as labour market reforms, and the progress made in implementing them.

A strong opening

Parliament passed four labour codes in 2019 and 2020, subsuming 29 central labour laws: The Code on Wages, 2019, the Industrial Relations Code, 2020, the Code on Social Security, 2020 and the Occupational Safety, Health and Working Conditions Code, 2020.

Points to cover

Merits

  • Simplification: Fewer laws, common definitions, single registration and returns, easier compliance.
  • Wider coverage: A statutory minimum wage for all workers, and social security extended to gig and platform workers and inter-state migrants.
  • Flexibility for employers: A higher threshold for prior government permission for lay-offs and closures, and fixed-term employment.
  • Women: Permission to work night shifts with safeguards.

Demerits

  • Unions argue the codes weaken job security and make strikes harder (longer notice periods).
  • Many small establishments fall outside thresholds; informal workers may still be left out in practice.
  • Much depends on rules framed by States, which may differ widely.

Progress

  • The codes came into force on 21 November 2025; the existing laws' relevant provisions continue during the transition while central and State rules are notified.
A balanced conclusion

The Labour Codes simplify an old and fragmented system and widen social security. Their success depends on fair rules, effective enforcement and trust between workers and employers.

GS III Q12Economy

What is the need for expanding the regional air connectivity in India? In this context, discuss the government’s UDAN Scheme and its achievements.

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Explain Say what it is and why or how it happens, step by step.
  • Discuss Cover the main aspects, with arguments on more than one side.

For Economy: Use current data and scheme names; a simple flowchart of cause and effect works well.

For this question: Explain the need, the scheme design, and then the achievements with the route and airport figures.

What the question asks

Explain why regional air connectivity needs to expand in India, and discuss the UDAN scheme and what it has achieved.

A strong opening

Much of India's air traffic is concentrated in a few metros, while many smaller towns had airports or airstrips with no regular flights. When the scheme began, 406 of 486 airports were under-served and only 27 were well served.

Points to cover

Need for regional connectivity

  • Links remote, hilly, North-Eastern and island regions where surface travel is slow.
  • Boosts tourism, trade, health access and investment in smaller cities; supports balanced regional development.
  • Reduces pressure on metro airports and builds a feeder network.

The UDAN scheme

  • Ude Desh ka Aam Naagrik (UDAN), the Regional Connectivity Scheme launched on 21 October 2016 under the National Civil Aviation Policy, 2016.
  • Airlines bid for routes; selected routes get Viability Gap Funding and concessions so that fares for a share of seats are capped.
  • Airport operators waive landing and parking charges; the Centre and States reduce fuel taxes.

Achievements

  • By October 2025, 649 routes had been operationalised, connecting 93 unserved and under-served airports including 15 heliports and 2 water aerodromes.
  • New airports in the North-East (Pasighat, Ziro, Hollongi, Tezu) and others such as Darbhanga have grown into busy airports.

Challenges

  • Many routes closed when the subsidy period ended; airline finances, aircraft availability and poor airport infrastructure limit sustainability.
A balanced conclusion

UDAN has made flying possible for many smaller towns. Its lasting success depends on routes that become viable without permanent subsidy.

GS III Q13Agriculture

What are the major challenges faced by Indian irrigation system in recent times? State the measures taken by the government for efficient irrigation management.

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • State Set out the points plainly and briefly.

For Agriculture: Name missions and schemes, give one figure, and link to farmer income and food security.

For this question: List the challenges, then the PMKSY components, ending with the micro-irrigation figure.

What the question asks

Identify the major challenges facing India's irrigation system today, and state the government's measures for efficient irrigation management.

A strong opening

About half of India's cropped area is still rainfed, and agriculture uses most of the country's fresh water, largely through flood irrigation of rice, wheat and sugarcane.

Points to cover

Major challenges

  • Groundwater depletion: Free or cheap power encourages over-pumping, especially in the north-west.
  • Low water-use efficiency: Flood irrigation wastes water; canals lose water through seepage and poor maintenance.
  • Gap between irrigation potential created and utilised, because of incomplete distribution networks.
  • Climate change: Erratic monsoons and heat stress; waterlogging and salinity in canal commands.
  • Inter-State water disputes and weak water-user participation.

Government measures

  • Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), launched on 1 July 2015, with components for completing major and medium projects (Accelerated Irrigation Benefit Programme), new minor irrigation sources (Har Khet Ko Pani) and watershed development.
  • Per Drop More Crop: 110.92 lakh hectares have been brought under micro-irrigation (drip and sprinkler).
  • Modernisation of Command Area Development and Water Management, approved in 2025-26, delivers water from projects through pressurised pipes.
A balanced conclusion

India's irrigation problem is less about building dams than using water well. Micro-irrigation, piped delivery and groundwater governance are the path to more crop per drop.

See the answer frameworkWhat to write, point by point

How to write this answer

  • Elucidate Explain clearly with examples, so the point becomes plain.
  • Discuss Cover the main aspects, with arguments on more than one side.

For Agriculture: Name missions and schemes, give one figure, and link to farmer income and food security.

For this question: Show how buffer stocks help both farmers and consumers before turning to storage problems.

What the question asks

Explain why buffer stocks matter for stabilising agricultural prices in India, and discuss the challenges of storing them.

A strong opening

A buffer stock is a reserve of foodgrains held by the government. The Food Corporation of India, set up on 14 January 1965 under the Food Corporations Act, 1964, procures grain at minimum support prices, stores it, and supplies the public distribution system.

Points to cover

Importance for price stability

  • Support for farmers: Procurement at MSP sets a floor price after harvest.
  • Protection for consumers: Releasing stocks through open market sales cools prices in lean seasons or after a poor monsoon.
  • Food security: Supplies the public distribution system and welfare schemes, and provides a reserve for droughts and emergencies.

Challenges in storage

  • Inadequate scientific storage: Grain held in open plinths (cover and plinth) is lost to rain, pests and rodents.
  • Excess stocks above norms lock up money and raise carrying costs.
  • Uneven storage: Capacity is concentrated in procuring States, far from consuming regions.
  • Leakages and quality deterioration, and high costs of transport and handling.

Way forward

  • Modern silos and warehouses, including through private partnerships; decentralised procurement; better stock management and digital tracking; diversifying stocks to pulses and millets.
A balanced conclusion

Buffer stocks protect both farmers and consumers from price swings. Storing them well, and holding only what is needed, is what makes the system efficient.

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Discuss Cover the main aspects, with arguments on more than one side.

For Science and Technology: Explain how it works (a small diagram), then applications for India and concerns.

For this question: Pick three technologies and give each a merit and a demerit, in a small table if time allows.

What the question asks

Discuss alternative technologies that can address the world's shortage of clean freshwater, with the merits and demerits of any three.

A strong opening

Growing demand, pollution and climate change are shrinking supplies of clean freshwater. Technology can add new sources of water or make used water fit again.

Points to cover

1. Desalination

  • Removes salt from seawater or brackish water, mostly by reverse osmosis, producing brine as a by-product; Chennai's Minjur plant, opened in July 2010, supplies the city.
  • Merits: An almost unlimited source for coastal cities, independent of rainfall.
  • Demerits: High energy use makes it costlier than surface or groundwater; brine discharge harms marine life.

2. Wastewater recycling (reclaimed water)

  • Treats sewage or industrial wastewater for reuse in industry, agriculture or even drinking (it can be treated to drinking water standards).
  • Merits: Turns a pollution problem into a resource; reliable supply near cities.
  • Demerits: Treatment cost, public reluctance to drink recycled water, and risk if treatment fails.

3. Atmospheric water generation

  • Extracts water vapour from the air by cooling it below its dew point, or using desiccants or fog collection.
  • Merits: Useful in remote and humid places without piped supply.
  • Demerits: Needs significant energy, works poorly in dry air, and gives small volumes.

Other options

  • Rainwater harvesting and managed aquifer recharge; solar stills and membrane filters for rural drinking water.
A balanced conclusion

No single technology can end water scarcity. Combining new sources with conservation and reuse offers the most sustainable path.

GS III Q16Science and Technology

What are asteroids? How real is the threat of them causing extinction of life? What strategies have been developed to prevent such a catastrophe?

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

For Science and Technology: Explain how it works (a small diagram), then applications for India and concerns.

For this question: Answer the three parts in turn, with Chicxulub for the threat and DART for the strategy.

What the question asks

Explain what asteroids are, how real the threat of an extinction-level impact is, and what strategies exist to prevent such a catastrophe.

A strong opening

Asteroids are small rocky or metallic bodies orbiting the Sun. Of the roughly one million known asteroids, most lie in the main asteroid belt between the orbits of Mars and Jupiter; near-Earth asteroids have orbits that bring them close to Earth.

Points to cover

How real the threat is

  • Past impacts: The Chicxulub crater in Mexico was formed slightly over 66 million years ago by an asteroid about ten kilometres wide, widely thought to have caused the mass extinction that ended the age of dinosaurs.
  • Large impacts are very rare, but even a body of a few hundred metres could devastate a region; smaller ones strike more often.

Strategies to prevent a catastrophe

  • Detection and tracking: Surveys with ground telescopes and space missions to find and monitor near-Earth objects.
  • Deflection by kinetic impact: NASA's Double Asteroid Redirection Test struck Dimorphos, a moonlet of the asteroid Didymos, on 26 September 2022 and shortened its orbit by 32 minutes, proving the method works.
  • Other ideas: Gravity tractors, ion beams, and nuclear explosions as a last resort.
  • Planning: International coordination for warning, evacuation and response.
A balanced conclusion

An extinction-level impact is unlikely in any human lifetime, but the stakes are too high to ignore. Early detection and tested deflection methods make it the one natural disaster humanity could prevent.

GS III Q17Disaster Management

What is disaster resilience? How is it determined? Describe various elements of a resilience framework. Also mention the global targets of Sendai Framework for Disaster Risk Reduction (2015–2030).

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Define Open with a precise definition before anything else.
  • Describe Give the main features in an orderly account.

For Disaster Management: Use the disaster cycle, a real Indian case, and the NDMA framework.

For this question: Define resilience precisely, then list the seven Sendai targets, which the question asks for by name.

What the question asks

Define disaster resilience, explain how it is determined, describe the elements of a resilience framework, and list the global targets of the Sendai Framework for Disaster Risk Reduction (2015-2030).

A strong opening

Disaster resilience is the ability of a community or system exposed to hazards to resist, absorb, adapt to and recover from their effects quickly and efficiently, while preserving its essential structures and functions.

Points to cover

How resilience is determined

  • Exposure and vulnerability of people and assets; capacity to cope (institutions, finance, skills); social factors such as poverty and health; quality of infrastructure; and speed of recovery after past disasters.

Elements of a resilience framework

  • Understanding risk: Hazard and vulnerability maps, data and early warning.
  • Governance: Laws, plans and institutions at every level (in India, the Disaster Management Act, 2005 and NDMA, SDMAs and DDMAs).
  • Investment in risk reduction: Resilient buildings and infrastructure, land-use planning, insurance.
  • Preparedness and response, and 'Build Back Better' in recovery and reconstruction.
  • Community participation and attention to the most vulnerable.

Sendai Framework: Seven global targets

  • Substantially reduce global disaster mortality and the number of people affected by 2030.
  • Reduce direct disaster economic loss in relation to global GDP, and damage to critical infrastructure and basic services, including health and educational facilities.
  • Substantially increase the number of countries with national and local disaster risk reduction strategies by 2020.
  • Enhance international cooperation to developing countries, and increase the availability of and access to multi-hazard early warning systems and risk information by 2030.
  • Its four priorities: Understanding disaster risk; strengthening disaster risk governance; investing in disaster risk reduction for resilience; and enhancing preparedness and building back better.
A balanced conclusion

Resilience shifts disaster management from relief to reducing risk before disasters strike. The Sendai targets give countries a measurable path towards that goal.

GS III Q18Disaster Management

Flooding in urban areas is an emerging climate-induced disaster. Discuss the causes of this disaster. Mention the features of two such major floods in the last two decades in India. Describe the policies and frameworks in India that aim at tackling such floods.

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Discuss Cover the main aspects, with arguments on more than one side.
  • Describe Give the main features in an orderly account.

For Disaster Management: Use the disaster cycle, a real Indian case, and the NDMA framework.

For this question: Give causes, then Mumbai 2005 and Chennai 2015 with their figures, then NDMA's 2010 guidelines.

What the question asks

Discuss the causes of urban flooding as an emerging climate-related disaster, describe two major Indian urban floods of the last two decades, and the policies and frameworks for tackling such floods.

A strong opening

Urban flooding happens when intense rain overwhelms a city's drainage. Impervious surfaces stop rain soaking into the ground, so runoff rises faster than drains can carry it.

Points to cover

Causes

  • Climate: More frequent extreme rainfall events.
  • Urbanisation: Concrete surfaces, loss of wetlands and lakes, and construction on floodplains and natural drains.
  • Drainage: Old, undersized and silted drains blocked by solid waste.
  • Coastal cities face high tides and storm surges that stop drains from emptying.

Mumbai, 26 July 2005

  • 944 mm of rain fell in 24 hours, the heaviest ever recorded in the city, and heavy rain continued for days; the city came to a standstill as the Mithi river and drains overflowed.

Chennai, November-December 2015

  • North-east monsoon rains, including 490 mm in 24 hours at Tambaram on 1 December, flooded the city; more than 500 people died and over 1.8 million were displaced.
  • Encroachment of lakes and floodplains and the release of water from reservoirs worsened the floods.

Policies and frameworks

  • NDMA's National Disaster Management Guidelines on Management of Urban Flooding (September 2010), the first such document in India; the Ministry of Urban Development is the nodal ministry.
  • They call for an expanded Doppler weather radar network covering all urban areas, early warning, storm-water drainage planning, and protecting water bodies.
  • Missions such as AMRUT and Smart Cities fund storm-water drains; cities prepare flood action plans and early warning systems.
A balanced conclusion

Urban floods are as much a planning failure as a climate event. Cities that protect wetlands, upgrade drains and warn early can turn heavy rain back into a manageable event.

How to write this answer

  • Examine Probe the issue in depth: Causes, evidence and consequences.

For Internal Security: Name laws, agencies and a recent case; balance security with rights.

For this question: Cover both borders, then BADP, the Vibrant Villages Programme and BIM in turn.

What the question asks

Examine the disputes and security challenges along India's borders with China and Pakistan, and describe the development undertaken there under the Border Area Development Programme (BADP) and the Border Infrastructure and Management (BIM) scheme.

A strong opening

India's land borders with China and Pakistan run through high mountains, deserts and plains. Both carry unresolved territorial disputes and active security threats.

Points to cover

China border: Issues and challenges

  • No agreed boundary: The Line of Actual Control is disputed in the western (Aksai Chin, Ladakh), middle and eastern (Arunachal Pradesh) sectors.
  • Face-offs and clashes, such as Galwan in 2020; China's rapid build-up of roads, airbases and 'xiaokang' border villages.

Pakistan border: Issues and challenges

  • The Line of Control in Jammu and Kashmir, Sir Creek, and the Siachen glacier.
  • Cross-border terrorism and infiltration, smuggling of drugs and weapons, and drones dropping consignments in Punjab and Jammu.

Border Area Development Programme (BADP)

  • Started in the 1980s along the western border with Pakistan; it funds roads, bridges, health facilities, schools, irrigation and sports facilities in villages within 10 km of the border, and by June 2020 covered nearly 400 blocks in 111 border districts.

Vibrant Villages Programme

  • Phase I (2022-2026) covered 662 priority villages on the China border with an outlay of Rs 4,500 crore; Phase II (2025-2029), with Rs 6,839 crore, covers 1,954 more villages along all land borders, including Pakistan and Bangladesh.

Border Infrastructure and Management (BIM)

  • A central umbrella scheme of the Ministry of Home Affairs for border fencing, floodlighting, border roads, border outposts and technological surveillance along the land borders.
A balanced conclusion

Secure borders need both strong defence and thriving border villages. Infrastructure and development make border populations the first line of national security.

GS III Q20Internal Security

Social media and encrypting messaging services pose a serious security challenge. What measures have been adopted at various levels to address the security implications of social media? Also suggest any other remedies to address the problem.

15 marks250 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Suggest End with practical, specific measures, not general wishes.

For Internal Security: Name laws, agencies and a recent case; balance security with rights.

For this question: Match each challenge with a measure (law, rules, institutions, platforms), then add remedies.

What the question asks

Explain the security challenges posed by social media and encrypted messaging, the measures adopted at various levels to address them, and further remedies.

A strong opening

Social media and end-to-end encrypted messaging connect billions of users, but the same reach and secrecy can be used to spread misinformation, incite violence, radicalise youth and plan crimes beyond the reach of law enforcement.

Points to cover

Security challenges

  • Fake news and deepfakes that trigger riots or lynchings; propaganda and radicalisation by terrorist groups.
  • Encrypted apps used for coordination by terrorists and criminals; difficulty tracing origins.
  • Cyber fraud, sextortion, and foreign influence operations; data harvesting.

Measures adopted

  • Law: The Information Technology Act, 2000 allows blocking of content (Section 69A) and interception under due process; in Shreya Singhal v. Union of India (2015) the Supreme Court struck down Section 66A for violating free speech.
  • Rules: The Information Technology Rules, 2021 set due-diligence and grievance redress duties for intermediaries, and Rule 4(2) requires significant messaging platforms to identify the first originator of information on a court or government order.
  • Institutions: CERT-In for cyber incidents, the Indian Cyber Crime Coordination Centre, and State cyber cells.
  • Platforms: Fact-checking, content moderation and limits on forwarding messages.

Further remedies

  • Digital literacy so citizens can spot fake news; quick response teams for viral misinformation.
  • Technical cooperation with platforms that respects encryption and privacy; international agreements on data access.
  • Clear, proportionate law with judicial oversight, in line with the right to privacy.
A balanced conclusion

Security on social media needs law, technology and an alert public working together. Measures must protect citizens without undermining free speech and privacy.
