GS III Q1Economy

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?

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

  • Distinguish Set out the differences point by point, ideally in a table.

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

For this question: Quote the 2025 report figures: HDI 0.685, IHDI 0.475, a 30.7 per cent loss; the gap is the answer.

What the question asks

Distinguish the Human Development Index (HDI) from the Inequality-adjusted HDI (IHDI), using India's figures, and explain why the IHDI is a better measure of inclusive growth.

A strong opening

UNDP's Human Development Index combines life expectancy, education (mean and expected years of schooling) and income per head into one number, the geometric mean of the three. The Inequality-adjusted HDI, introduced in the 2010 Human Development Report, discounts each dimension for how unequally it is shared.

Points to cover

How they differ

  • HDI measures average achievement; the IHDI reduces it by the inequality within each dimension (using the Atkinson measure), so it shows the level of human development the typical person actually enjoys.
  • If everyone were equal the two would match; the gap between them is the loss due to inequality.

India's figures (Human Development Report 2025, data for 2023)

  • India ranks 130 of 193 countries with an HDI of 0.685, in the medium human development group.
  • Its IHDI is 0.475: Inequality reduces India's HDI by 30.7 per cent, one of the largest losses in the region, driven by gaps in income, education and health.

Why the IHDI is the better measure of inclusive growth

  • Inclusive growth means gains shared across groups; the HDI can rise while the poor fall behind, but the IHDI falls when gaps widen.
  • It shows which dimension holds a country back, guiding policy on schooling quality, health access or income support.
  • Limits: It does not capture gaps between social groups (caste, gender, region) directly; the Gender Development Index and the Multidimensional Poverty Index complement it.
A balanced conclusion

India's rising HDI shows progress; its IHDI shows how unevenly that progress is shared. Narrowing the 30.7 per cent loss is the real test of inclusive growth.

GS III Q2Economy

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?

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

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

For this question: Two clear parts: Challenges, then responses; name the EFTA, UK and EU agreements with their dates.

What the question asks

Identify the challenges the Indian economy faces as the world turns from free trade and multilateralism to protectionism and bilateral deals, and suggest how India can meet them.

A strong opening

The rules-based trading order built around the WTO has weakened: Its Appellate Body cannot rule, large economies raise tariffs, and trade is increasingly governed by bilateral and regional agreements.

Points to cover

Challenges for India

  • Market access: Higher tariffs in major markets hurt labour-intensive exports like textiles, gems and leather; in August 2025 the United States added a 25 per cent tariff on Indian goods over India's purchases of Russian oil.
  • Outside regional blocs: India stayed out of RCEP, the large Asian trade agreement signed in November 2020, which can divert trade to member countries.
  • Non-tariff barriers: Carbon border taxes and stricter standards in rich markets.
  • Weaker dispute settlement leaves India with less protection against unilateral measures.
  • Supply-chain shifts and pressure on the rupee and current account.

How India is responding

  • Bilateral and plurilateral deals: The India-EFTA agreement entered into force on 1 October 2025 with a pledge of 100 billion dollars of investment over 15 years; the India-UK agreement came into effect on 15 July 2026; an India-EU agreement was concluded on 27 January 2026.
  • Domestic competitiveness: Production Linked Incentive schemes, logistics reform under PM Gati Shakti and easier compliance.

What more is needed

  • Diversify markets and products, raise standards and quality, protect sensitive farm and dairy sectors in deals, and keep pressing for WTO reform with like-minded countries.
A balanced conclusion

Protectionism raises the cost of trade but also rewards countries that are competitive and well connected. India can turn the shift to its advantage with good deals abroad and reform at home.

GS III Q3Agriculture

Explain the factors influencing the decision of the farmers on the selection of high value crops 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: Group the factors as economic, physical, market and institutional, with one Indian example each.

What the question asks

Explain the factors that decide whether Indian farmers choose high-value crops (fruits, vegetables, flowers, spices and other commercial crops) over staple grains.

A strong opening

High-value crops earn more per hectare than cereals, and India's horticulture output (369.1 million tonnes in 2024-25) now exceeds its foodgrain output (357.7 million tonnes). Yet many farmers still grow grains, because the choice depends on more than price.

Points to cover

Economic factors

  • Expected price and demand: Urban incomes and exports raise demand for fruit, vegetables and dairy-linked fodder.
  • Price risk: Perishable crops have volatile prices and, unlike wheat and rice, little assured procurement at the Minimum Support Price.
  • Higher costs of seed, labour, inputs and investment (orchards take years to bear fruit), so credit access matters.

Physical factors

  • Assured irrigation, suitable soil and climate (apples in the hills, grapes and pomegranates in Maharashtra).
  • Small and fragmented holdings: About 86 per cent of holdings are small or marginal, which limits risk-taking.

Market and infrastructure

  • Nearness to markets and roads, cold storage and processing; online trading through e-NAM and Farmer Producer Organisations widen access.

Institutional and social factors

  • Knowledge and extension support, crop insurance, contract farming, government missions such as the Mission for Integrated Development of Horticulture, and peer examples in the village.
A balanced conclusion

Farmers shift to high-value crops when markets, water and risk cover are in place. Building those, not just advising diversification, is what changes cropping patterns.

GS III Q4Agriculture

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

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

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

For this question: Draw the chain as a simple flowchart from farm gate to consumer, then give its significance.

What the question asks

Elaborate the scope (the stages and players) of supply chain management for farm commodities in India and its significance for farmers, consumers and the economy.

A strong opening

Supply chain management covers everything from the farm gate to the consumer: Aggregation, grading, storage, transport, processing, wholesale and retail. In farming, where produce is perishable and farms are small, how the chain works decides both farmer income and consumer prices.

Points to cover

Scope

  • Pre-harvest: Inputs, credit and crop planning to match market demand.
  • Post-harvest: Aggregation through Farmer Producer Organisations, grading, packaging, warehousing and cold chains.
  • Marketing: Mandis under State APMC laws, the online e-NAM platform launched on 14 April 2016, and direct sales to processors and retailers.
  • Processing and exports, with traceability and quality standards.

Significance

  • Farmers: Fewer intermediaries and lower losses raise the share of the consumer's price that reaches the grower.
  • Consumers: Steadier supply and prices, as Operation Greens aims for tomato, onion and potato.
  • Economy: Less waste, more food processing jobs, exports and food security.

Gaps to close

  • Shortage of cold storage near farms, fragmented mandis, poor rural roads and weak price information.
  • Steps: Infrastructure funds for storage and processing, digital platforms, FPO aggregation and warehouse-based credit.
A balanced conclusion

An efficient farm supply chain links small farmers to large markets. Investing in it raises farm incomes and holds down food prices at the same time.

GS III Q5Science and Technology

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?

10 marks150 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: Three parts as asked: India's programme, India's ITER deliverables, and implications for global energy.

What the question asks

Trace how India's fusion energy programme developed, state India's contributions to ITER, and explain what ITER's success would mean for the world's future energy.

A strong opening

Nuclear fusion joins light nuclei (isotopes of hydrogen) to release energy, the process that powers the Sun. ITER, being built near Cadarache in southern France by seven partners, aims to show that fusion can work at power-plant scale.

Points to cover

India's fusion programme

  • The Institute for Plasma Research, Gandhinagar, began tokamak experiments with ADITYA in 1989.
  • A decision of 1995 led to SST-1, a superconducting steady-state tokamak, and the institute came under the Department of Atomic Energy.

India and ITER

  • India is one of seven ITER members (with China, the European Union, Japan, Russia, South Korea and the United States); the partners formally agreed to fund the project on 21 November 2006.
  • India's share is about 10 per cent, delivered mostly 'in kind' as components built by Indian industry.
  • Larsen & Toubro built and installed the cryostat, the huge vacuum vessel that encloses the reactor, completed on 9 June 2020; India's other deliverables include cryolines, in-vessel shielding and the cooling water systems.

Implications of success

  • Almost limitless fuel: Deuterium from sea water and tritium bred from lithium.
  • No carbon emissions while running and far less long-lived radioactive waste than fission; no chain reaction that can run away.
  • Energy security for importers like India and a route to deep decarbonisation, though power plants would come only after ITER's research phase from about 2034.
A balanced conclusion

India is a full technical partner in the world's largest fusion experiment. If ITER succeeds, fusion could become a clean, secure source of power in the second half of the century.

GS III Q6Science and Technology

How can India achieve energy independence through clean technology by 2047? How can biotechnology can play a crucial role in this endeavour?

10 marks150 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: Pair each clean technology with a target, then give biotechnology its own block (biofuels, biogas, BioE3).

What the question asks

Explain how India can become energy independent by 2047 through clean technologies, and show the specific role biotechnology can play.

A strong opening

Energy independence means meeting India's energy needs mainly from domestic, clean sources rather than imported oil, gas and coal. India has already reached 50 per cent of its installed electricity capacity from non-fossil sources, five years ahead of its 2030 target under the Paris Agreement.

Points to cover

Clean-technology pathway

  • Electricity: Solar, wind, hydro and nuclear power with grid storage (batteries, pumped hydro) to replace coal.
  • Transport: Electric vehicles, flex-fuel vehicles and green hydrogen for heavy transport.
  • Industry: Green hydrogen for steel, fertiliser and refining; energy efficiency across sectors.
  • Domestic manufacturing of solar modules, batteries and electrolysers, and secure supplies of critical minerals.

Role of biotechnology

  • Biofuels: The 20 per cent ethanol blending target (E20), first set for 2030, was advanced to 2025 and achieved; second-generation ethanol from crop residue avoids using food crops.
  • Compressed biogas from agricultural, dairy and municipal waste can replace imported gas in transport and cooking.
  • Engineered microbes and enzymes for cheaper biomass conversion, algal fuels and biological routes to hydrogen.
  • The BioE3 policy, approved by the Cabinet in August 2024, supports biomanufacturing hubs and biofoundries across six thematic sectors.

Conditions for success

  • Storage and grid investment, stable policy, finance, skills and care for food security and land use.
A balanced conclusion

Clean power, electric mobility and green hydrogen can cut imports, while biotechnology turns India's farm and urban waste into fuel. Together they can make energy independence by 2047 realistic.

GS III Q7Environment

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

10 marks150 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.

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

For this question: A small capture, use, store diagram plus one real project (Sleipner) makes the definition concrete.

What the question asks

Define Carbon Capture, Utilisation and Storage (CCUS) and assess its potential role in tackling climate change, with examples and limits.

A strong opening

CCUS captures carbon dioxide from large point sources, such as power plants, cement works or gas processing, and either uses it in products or stores it permanently, usually deep underground. It addresses emissions that are hard to remove by switching fuels alone.

Points to cover

How it works

  • Capture: CO2 is separated from flue gases or industrial processes.
  • Utilisation: Captured CO2 can be turned into methanol, urea, polymers and building materials.
  • Storage: CO2 is injected into deep geological formations such as depleted oil and gas fields or saline aquifers; the first large dedicated project began at the Sleipner gas field in Norway in 1996.

Potential role

  • Cutting emissions from cement, steel, chemicals and fertiliser, where process emissions remain even with clean electricity.
  • Enabling low-carbon hydrogen from gas or coal, and negative emissions when combined with bioenergy.
  • For India, coal will remain part of the energy mix for years, so CCUS can support the net-zero goal for 2070.

Limits

  • High cost and energy penalty; most captured CO2 today is used for enhanced oil recovery, which yields more oil; storage needs monitoring for leaks; it can delay the shift away from fossil fuels if used as an excuse.
A balanced conclusion

CCUS is not a substitute for renewable energy, but a tool for the hardest emissions. With falling costs and clear policy, it can be an important part of India's path to net zero.

GS III Q8Environment

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?

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

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

For this question: Sketch the freshwater lens over seawater and show the wedge moving inland as pumping rises.

What the question asks

Explain why seawater is entering the coastal aquifers of India, and set out the measures that can control this hazard, with Indian examples.

A strong opening

In coastal aquifers, fresh groundwater normally floats on and holds back denser seawater. When fresh water is pumped out faster than it is replaced, or sea level rises, the saltwater wedge moves inland and wells turn salty, a process known as seawater (or saltwater) intrusion.

Points to cover

Causes

  • Over-extraction of groundwater for farms, industries and cities lowers the water table, letting seawater flow in, as in coastal Gujarat (Saurashtra and Kutch) and around Chennai.
  • Sea level rise caused by climate change pushes the boundary landward.
  • Less recharge because of paved surfaces, deforestation and failed monsoons.
  • Canals, navigation channels and sand mining in rivers let tides carry salt further inland.

Consequences

  • Salty drinking water, loss of farmland, damage to crops and industries, and costly treatment.

Remedial measures

  • Regulating groundwater use and drilling in notified coastal zones.
  • Artificial recharge: Check dams, recharge wells and ponds, and tidal regulators that hold fresh water in estuaries, used along Gujarat's coast.
  • Managed aquifer recharge with treated wastewater and rainwater harvesting.
  • Protecting mangroves and coastal wetlands, and monitoring salinity with observation wells.
A balanced conclusion

Seawater intrusion is mostly a groundwater management problem made worse by rising seas. Recharge and regulation together can hold the line and protect coastal water supplies.

GS III Q9Internal Security

Terrorism is a global scourge. How has it manifested in India? Elaborate with contemporary examples. What are the counter measures adopted by the State? Explain.

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

For this question: Give dated examples (Pahalgam 2025, Mumbai 2008) and match each with a counter-measure.

What the question asks

Describe how terrorism has shown itself in India, with recent examples, and explain the counter-measures the State has adopted.

A strong opening

Terrorism is the use of violence against civilians to spread fear for political ends. India has faced it in several forms for decades, much of it supported from across the border.

Points to cover

Manifestations in India

  • Cross-border terrorism in Jammu and Kashmir: On 22 April 2025, militants killed 26 civilians, most of them tourists, near Pahalgam.
  • Attacks on cities: The Mumbai attacks of November 2008 showed sea-borne infiltration and urban siege tactics.
  • Insurgency and extremism: Left Wing Extremism in central India and armed groups in parts of the North-East, though both have declined sharply.
  • New forms: Online radicalisation, terror funding through crypto and hawala, and drones dropping weapons across the border.

Counter-measures

  • Laws: The Unlawful Activities (Prevention) Act, amended in 2019 to let the Union designate individuals as terrorists.
  • Institutions: The National Investigation Agency, set up under the NIA Act, 2008 after the Mumbai attacks, with nationwide jurisdiction; intelligence sharing through the Multi Agency Centre.
  • Military response: Operation Sindoor, begun on 7 May 2025, struck terrorist infrastructure across the border after Pahalgam.
  • Diplomacy: Pressing for FATF action against terror financing and for a UN Comprehensive Convention on International Terrorism.
  • Coastal security, border fencing and technology, and de-radicalisation and development in affected areas.
A balanced conclusion

India's response has shifted from defence to deterrence, backed by stronger laws and agencies. Lasting success needs equal attention to intelligence, rights-respecting policing and international cooperation.

GS III Q10Internal Security

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?

10 marks150 words8 min 45 s

See the answer frameworkWhat to write, point by point

How to write this answer

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

For this question: Define LWE, show its human cost, then strategy and the official 2026 outcome, attributed to the government.

What the question asks

Explain what Left Wing Extremism (LWE) is, how it affects people, and what the government has done to end it, given the stated aim of eliminating it by 2026.

A strong opening

Left Wing Extremism, or Naxalism, is an armed movement inspired by Maoist ideology that seeks to overthrow the State through violence. It took root in the forested tribal belt of central and eastern India, the so-called Red Corridor.

Points to cover

How people are affected

  • Violence: Killings of civilians and security personnel, extortion and destruction of roads, schools and mobile towers.
  • Development stalls: Schools, health centres, roads and banking cannot reach affected villages, deepening tribal poverty.
  • Tribal communities are caught between the insurgents and security operations, and suffer displacement and loss of livelihoods.

Government strategy

  • On 24 August 2024 the Union set a target of making the country free of Naxalism by 31 March 2026.
  • Security: More camps in core areas, coordinated operations by central and State forces and choking of funds and arms.
  • Development: Roads, mobile towers, banks, schools and welfare schemes pushed into affected districts.
  • Surrender and rehabilitation policies, and rights such as those under the Forest Rights Act to address grievances.

Outcome so far

  • The government states that LWE-affected districts fell from 126 in 2014 to zero by March-April 2026, and that India became effectively free from Naxalism on 31 March 2026.
  • Sustaining peace now depends on development, good governance and trust in the formerly affected areas.
A balanced conclusion

Combined security and development pressure has broken the LWE movement. The lasting test is whether governance and opportunity fill the space it leaves.

GS III Q11Economy

Explain how the Fiscal Health Index (FHI) can be used as a tool for assessing the fiscal performance of states in India. In what way would it encourage the states to adopt prudent and sustainable fiscal policies?

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.

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

For this question: Name the five sub-indices; they are the heart of how the FHI works as a tool.

What the question asks

Explain how NITI Aayog's Fiscal Health Index (FHI) works as a tool to assess the fiscal performance of States, and how it can encourage them to follow prudent and sustainable fiscal policies.

A strong opening

The Fiscal Health Index, first released by NITI Aayog in January 2025, ranks 18 major States on a composite score built from five sub-indices: Quality of Expenditure, Revenue Mobilisation, Fiscal Prudence, Debt Index and Debt Sustainability. A second edition followed for 2023-24.

Points to cover

What it measures

  • Quality of Expenditure: How much spending goes to capital assets and development rather than committed items.
  • Revenue Mobilisation: The State's own tax and non-tax revenue.
  • Fiscal Prudence: Control of fiscal and revenue deficits.
  • Debt Index and Debt Sustainability: Interest burden and whether debt grows faster than the economy.

As an assessment tool

  • One composite score allows comparison across States and over time; Odisha topped the first edition with a score of 67.8.
  • Sub-index scores show where each State is weak, guiding targeted reform; the second edition ranks North-Eastern and Himalayan States separately.

How it encourages prudent policy

  • Competitive federalism: Public rankings create peer pressure and reputational incentives.
  • Signals to lenders and investors about creditworthiness.
  • A common evidence base for the Union, the Finance Commission and State legislatures.

Limits

  • Based on past data; does not capture off-budget borrowing fully; States differ in needs, so rankings must be read with context.
A balanced conclusion

The FHI turns State finances into comparable, public information. Used well, it rewards fiscal discipline without ignoring the development spending States must undertake.

GS III Q12Economy

Discuss the rationale of the Production Linked Incentive (PLI) scheme. What are its achievements? In what way can the functioning and outcomes of the scheme be improved?

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: Rationale, achievements with the March 2026 figures, then specific reforms such as value addition.

What the question asks

Discuss why the Production Linked Incentive (PLI) scheme was introduced, what it has achieved, and how its working and results can be improved.

A strong opening

PLI schemes, launched from 2020, give companies incentives linked to the increase in their domestic production and sales over a base year. They cover 14 sectors, from mobile phones and electronics to pharmaceuticals, food processing, textiles, solar modules and specialty steel.

Points to cover

Rationale

  • Make Indian manufacturing competitive and reduce dependence on imports in strategic sectors.
  • Attract global firms seeking to diversify supply chains, build scale and integrate India into global value chains.
  • Create jobs and raise exports.

Achievements

  • As on 31 March 2026, PLI schemes had led to actual investment of over ₹2.40 lakh crore and employment of over 14.15 lakh, direct and indirect, with cumulative exports above ₹15.2 lakh crore.
  • Mobile phones are the clearest success: India has become a major exporter instead of an importer.

Problems seen

  • Uneven results: Some sectors have attracted little investment and disbursement is slow.
  • Much value in electronics is still imported components with low domestic value addition.
  • Incentives favour large firms; job numbers are reported by beneficiaries.

Improvements

  • Tie incentives to domestic value addition and component ecosystems; faster, simpler disbursement; independent evaluation; support for MSMEs in the supply chain; and pairing PLI with reforms in logistics, power and skills.
A balanced conclusion

PLI has shown that targeted incentives can attract manufacturing at scale. Deepening local value addition will decide whether it builds lasting industrial capacity.

Sources: PIB: PLI schemes attract over ₹2.40 lakh crore investment, generate more than 14.15 lakh jobs (21 July 2026)

GS III Q13Environment

Examine the factors responsible for depleting groundwater in India. What are the steps taken by the government to mitigate such depletion of groundwater?

15 marks250 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.

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

For this question: Use the 2025 assessment numbers (730 of 6,762 units over-exploited) before listing causes and steps.

What the question asks

Examine why groundwater is being depleted in India and set out the steps the government has taken to slow and reverse the depletion.

A strong opening

India is the world's largest user of groundwater, which supplies most of its irrigation and drinking water. The 2025 assessment puts total annual extraction at 247.22 billion cubic metres and classifies 730 of 6,762 assessment units (10.8 per cent) as over-exploited.

Points to cover

Causes of depletion

  • Irrigation: Water-intensive crops such as paddy and sugarcane in dry regions like Punjab, Haryana and parts of Maharashtra.
  • Free or cheap electricity for farm pumps, which encourages over-pumping.
  • Rapid urbanisation and industry; paved surfaces reduce recharge.
  • Weak regulation: Landowners own the groundwater under their land, and there is little metering.
  • Climate variability and erratic monsoons.

Steps taken

  • Atal Bhujal Yojana for community-led groundwater management in water-stressed States.
  • Jal Shakti Abhiyan, 'Catch the Rain' and Mission Amrit Sarovar for recharge structures and water bodies.
  • Since September 2025, at least 65 per cent of rural employment guarantee funds must go to water conservation works in over-exploited and critical blocks.
  • Micro-irrigation under PMKSY ('Per Drop More Crop'), and Central Ground Water Authority rules on extraction.

What more is needed

  • Crop diversification away from water-intensive crops, power and pricing reform, aquifer mapping and community monitoring.
A balanced conclusion

Groundwater is being used faster than it is replaced in many blocks. Recharge, efficient irrigation and smarter incentives must work together to restore the balance.

GS III Q14Agriculture

Examine the scope of the food processing industries in India. Elaborate the measures taken by the government in the food processing industries for generating employment opportunities.

15 marks250 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.

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

For this question: Show scope with the 12.83 per cent employment share, then the schemes that create jobs.

What the question asks

Examine the scope of food processing industries in India and describe the government's measures in this sector aimed at creating jobs.

A strong opening

Food processing turns farm, dairy, fisheries and meat produce into higher-value products. It links farmers to markets and is the largest employer in India's registered manufacturing, with 12.83 per cent of its employment.

Points to cover

Scope

  • India's large output of grains, fruit, vegetables, milk and fish, with high post-harvest losses, offers raw material and room for value addition.
  • Growing urban demand for packaged and ready-to-eat food, and export markets.
  • The sector grew by an average 6.55 per cent a year over nine years, faster than manufacturing as a whole.
  • Its rural location and small units make it labour-intensive and suited to women and self-help groups.

Government measures for employment

  • Pradhan Mantri Kisan Sampada Yojana: Mega food parks, cold chains and processing units.
  • PLI Scheme for the Food Processing Industry (PLISFPI): Incentives for scale and Indian brands abroad.
  • PM Formalisation of Micro Food Processing Enterprises (PMFME): Credit-linked subsidies and seed capital for micro units and SHG members.
  • Operation Greens for perishable crops, FDI allowed through the automatic route, and the World Food India platform.

Challenges

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: Give each application a farmer benefit, and end with the need for trials and regulation.

What the question asks

Explain how nanotechnology is advancing agriculture and how it can improve the social and economic condition of farmers, with examples and cautions.

A strong opening

Nanotechnology works with materials at the scale of billionths of a metre, where particles behave differently because of their large surface area. In farming, it allows inputs to be delivered precisely and in smaller amounts.

Points to cover

Advances in agriculture

  • Nano fertilisers: Liquid nano urea and nano DAP, sprayed on leaves, aim to cut the use of bulk granular fertiliser; the Government notified Nano DAP under the Fertilizer Control Order, 1985 on the basis of bio-efficacy and toxicology trials.
  • Nano pesticides and controlled-release formulations that reduce the quantity applied and run-off.
  • Nano sensors for soil moisture, nutrients and disease, supporting precision farming.
  • Nano-coatings and packaging that extend shelf life and cut post-harvest losses.

Socio-economic benefits for farmers

  • Lower input and transport costs (a small bottle replaces a heavy bag), and possible yield gains.
  • Less soil and water pollution, protecting long-term productivity.
  • Better prices from reduced losses and better quality produce.

Cautions

  • Field results vary and need independent, long-term trials; the effects of nanoparticles on soil life and health need study; farmers need training and affordable access.
A balanced conclusion

Nanotechnology can make Indian farming more precise, cheaper and cleaner. Its benefits will reach farmers only with rigorous testing, regulation and extension support.

GS III Q17Environment

Mineral resources are fundamental to the country's economy and these are exploited by mining. Why is mining considered an environmental hazard? Explain the remedial measures required to reduce the environmental hazard due to mining.

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.

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

For this question: Take hazards by medium (land, water, air, people), then remedies in the same order.

What the question asks

Explain why mining is an environmental hazard and set out the remedial measures that can reduce its harm.

A strong opening

Minerals such as coal, iron ore and bauxite feed India's industry and power, and most lie in the forested, tribal regions of the peninsular plateau. Extracting them, especially by open-cast mining, changes land, water and air over large areas.

Points to cover

Why mining is hazardous

  • Land: Loss of forests and topsoil, dumps of overburden, and abandoned pits; underground mines can cause land subsidence and mine fires, as at Jharia.
  • Water: Acid mine drainage from sulphide-bearing rocks, contamination by heavy metals, silting of rivers and falling water tables.
  • Air: Dust and particulate pollution from blasting, crushing and transport, causing lung disease.
  • Biodiversity and people: Fragmentation of habitats and corridors, and displacement of tribal communities.

Remedial measures

  • Prior environmental impact assessment, forest clearance and public hearings, with compensatory afforestation.
  • Progressive mine closure and reclamation: Backfilling, topsoil replacement and replanting during operations, not after.
  • Pollution control: Dust suppression, covered transport, treatment of mine water and safe tailings dams.
  • District Mineral Foundations, funded by mining companies, to spend on the welfare and environment of affected areas.
  • Better technology: Underground and less-polluting methods, satellite and drone monitoring of mining leases.
A balanced conclusion

Mining will remain essential, but its costs fall on land, water and local communities. Enforcing reclamation and sharing benefits with affected people make it sustainable.

What the question asks

Set out the main challenges to internal security and the peace process in the North-Eastern States, and map the peace accords and agreements the government has reached in the past decade.

A strong opening

The North-East has seen insurgencies rooted in ethnic identity, land and autonomy since the 1950s. Violence has fallen sharply in the last decade through a series of agreements, but new and old challenges remain.

Points to cover

Challenges

  • Ethnic conflict: Since 3 May 2023, violence between the Meitei and Kuki-Zo communities in Manipur has killed many and displaced thousands.
  • Unresolved Naga issue: Talks under the Framework Agreement of 3 August 2015 with the NSCN(IM) remain unfinished over a separate flag and constitution.
  • Porous borders with Myanmar, Bangladesh and Bhutan; arms and drug trafficking; inter-State boundary disputes.
  • Groups outside the process and the law-and-order burden of disarmament and rehabilitation.

Peace accords and agreements of the past decade

  • NLFT(SD), Tripura (August 2019), with the surrender of 88 cadres.
  • Bru-Reang agreement (16 January 2020), settling displaced Bru families in Tripura, and the Bodo Accord, Assam (27 January 2020).
  • Karbi Anglong Agreement, Assam (September 2021).
  • UNLF (Pambei faction), Manipur, ceasefire agreement (29 November 2023), and the pro-talks ULFA, which disbanded after its peace treaty of 2023.
  • NLFT and ATTF, Tripura (4 September 2024).
  • An agreement with the Eastern Nagaland People's Organisation and the Nagaland government (February 2026).

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

For this question: Open with the 95 and 70 per cent trade figures, then challenges and a way forward.

What the question asks

Explain why maritime security is vital for India's sea trade, discuss the maritime and coastal security challenges, and suggest a way forward.

A strong opening

Nearly 95 per cent of India's trade by volume and about 70 per cent by value moves by sea. India's long coastline, island territories and position astride Indian Ocean shipping lanes make maritime security an economic as well as a strategic necessity.

Points to cover

Why it is vital

  • Energy imports and exports pass through chokepoints such as the Strait of Hormuz, Bab-el-Mandeb and Malacca.
  • Ports, offshore oil fields such as Mumbai High, undersea cables and the Exclusive Economic Zone hold economic value.

Challenges

  • Piracy and attacks on shipping, such as those in the Red Sea and Gulf of Aden; the Indian Navy has escorted and rescued ships in the region.
  • Terrorism from the sea, as in the Mumbai attacks of November 2008.
  • Smuggling of drugs and arms, illegal fishing and human trafficking.
  • Growing presence of extra-regional navies and dual-use port projects in the Indian Ocean.
  • Coastal gaps: Many agencies, small fishing boats that are hard to track, and uneven State marine police capacity.

What India is doing

  • Coastal security reorganised after 2008, with the Coast Guard, Navy and marine police working together and coastal radar chains.
  • Regional outlook: SAGAR, now widened as MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions), and an information fusion centre for shipping in the Indian Ocean.

Way forward

  • Better maritime domain awareness with satellites and drones, unified command for coastal security, a stronger navy and shipbuilding base, and partnerships with Indian Ocean states.
A balanced conclusion

Secure seas are the lifeline of India's trade and energy. Investing in awareness, capability and partnerships keeps that lifeline open.
