How globalization has led to the reduction of employment in the formal sector of the Indian economy? Is increased informalization detrimental to the development of the country?

Approach · directive: “how / is … detrimental”

What it asks · Explain the channels through which opening to global competition held back formal-sector jobs, then take a reasoned position on whether the rise of informal work harms development.

The question has 2 parts — answer each

  1. Explain how globalisation has reduced employment in the formal sector of the Indian economy
  2. Is increased informalisation detrimental to development: take a reasoned position with both sides

Open with · Since 1991 output has grown faster than secure, contract-based jobs, and most Indian workers now work without written contracts or social security.

Cover

  • Capital-intensive growth: import competition and new technology let organised firms raise output with fewer workers, so growth outran formal job creation.
  • Contractualisation: to match global prices, firms hire contract and casual labour through contractors, so informal workers now sit inside organised units too.
  • Restructuring: weak units closed or shrank under import competition, public sector jobs were pruned, and services growth favoured skilled work in IT and finance.
  • Value chains and outsourcing: production is pushed down to small units, home-based and piece-rate workers, with lower wages and little protection.
  • Detrimental: low productivity and wages, no social security, a narrow tax base, weak skill formation, little bargaining power and heavy exposure to shocks.
  • Counterview: informal work absorbs surplus labour and supports livelihoods; the problem is low productivity and lack of protection, not informality as such.
  • Way forward: labour-intensive manufacturing, formalising MSMEs, skilling, portable social security for all workers, and reform of rigid labour rules with safeguards.

Close with · The aim should be more formal jobs together with decent, protected informal work, so that workers gain from globalisation instead of only bearing its costs.

Model answer · 267 words (UPSC limit 200) · Minimalist IAS

Since the 1991 reforms output has grown far faster than secure, contract-based jobs. The National Commission for Enterprises in the Unorganised Sector (2007) found that informal workers made up 92 per cent of India's workforce, and a growing number of them work inside organised firms.

How globalisation cut formal jobs

  • Capital-intensive growth: import competition and easy access to imported machinery let organised firms raise output with fewer workers, so growth outran formal job creation.
  • Contractualisation: to match global prices while avoiding the retrenchment rules of the Industrial Disputes Act, 1947, firms hire casual and contract labour through contractors; informal workers now sit inside organised units.
  • Restructuring: weaker units closed or shrank under import competition, public sector employment was pruned, and services growth favoured skilled work in IT and finance rather than mass employment.
  • Global value chains: production is pushed down to small units, home-based and piece-rate workers, with lower wages and little protection.

Is informalisation detrimental?

Largely, yes.

  • Low productivity and wages, no social security, little bargaining power and heavy exposure to shocks keep workers poor even when the economy grows.
  • A narrow tax base, weak skill formation and thin domestic demand slow the shift to higher-value activity.
  • Counterview: informal work absorbs surplus labour and sustains livelihoods; the real problem is low productivity and lack of protection, not informality as such.

Way forward

  • Labour-intensive manufacturing and exports, formalising MSMEs, skilling, portable social security for all workers, and labour law reform with safeguards.

Globalisation can raise incomes only if its gains reach workers: more formal jobs, and decent, protected work for those who remain informal, must go together.

Women empowerment in India needs gender budgeting. What are the requirements and status of gender budgeting in the Indian context?

Approach · directive: “what”

What it asks · Explain why empowering women needs gender-responsive budgets, list what is required to make gender budgeting work, and describe where India stands.

The question has 3 parts — answer each

  1. Explain why women's empowerment in India needs gender budgeting
  2. State the requirements for gender budgeting to work in the Indian context
  3. Describe the status of gender budgeting in India

Open with · Gender budgeting is not a separate budget for women but a way of checking whether public spending reaches women as fairly as men.

Cover

  • Need: women's needs in health, education, work and safety are shaped by unpaid care, lower incomes and unequal access to public services.
  • Requirements: sex-disaggregated data, gender-sensitive analysis of schemes, clear allocations, outcome indicators, gender audits and trained officials.
  • Requirements: participation of women in planning, especially through panchayats, and a gender lens on revenue and taxation as well as spending.
  • Status, Union: a Gender Budget Statement has accompanied the Union Budget since 2005-06: Part A for schemes with 100% provision for women, Part B for schemes where women get at least 30% of the provision.
  • Status, coverage: it has widened to 49 ministries and departments in 2025-26 (38 in 2024-25), ministries have gender budgeting cells, and many States publish their own statements.
  • Gaps: the statement is a small share of total expenditure, shows allocations rather than outcomes, and many departments treat it as a formality.
  • Way forward: link the statement to outcomes and audits, extend it to all ministries and to local bodies, and publish sex-disaggregated data.

Close with · Gender budgeting turns commitments to women into measurable spending; its value lies in outcomes for women, not in the size of the statement.

Model answer · 291 words (UPSC limit 200) · Minimalist IAS

Gender budgeting is not a separate budget for women; it applies a gender lens to the whole budget to check whether public spending reaches women as fairly as men.

Why empowerment needs it

  • Women carry unpaid care work, earn less and use public services less, so gender-neutral spending often serves men more; deliberate allocations in health, education, safety and livelihoods correct this.
  • It turns the constitutional promise of equality and special provision for women (Articles 14 and 15(3)) into measurable spending and outcomes.

Requirements

  • Sex-disaggregated data and gender analysis of every scheme before money is allocated.
  • Clear allocations tied to outcome indicators, gender audits and evaluation after spending.
  • Trained officials and working gender budgeting cells in ministries and States.
  • Women's participation in planning, especially through panchayats and gram sabhas.
  • A gender lens on revenue too: taxes, user charges and subsidies affect women differently.

Status in India

  • A Gender Budget Statement has accompanied the Union Budget since 2005-06: Part A lists schemes with 100 per cent provision for women, Part B those where women receive at least 30 per cent.
  • The Ministry of Women and Child Development coordinates it; ministries have gender budgeting cells and several States publish their own statements (since then, coverage has widened to 49 ministries and departments in 2025-26).
  • Gaps: the statement is a small share of total expenditure, reports allocations rather than outcomes, and many departments treat it as a formality; local bodies remain largely outside it.

Way forward

  • Link the statement to outcomes and audits, extend it to all ministries and local bodies, and publish sex-disaggregated data.

Gender budgeting matters for what it changes in women's lives, not for the size of the statement; outcome tracking and audits will make it a real instrument of empowerment.

GS Paper III 2016 · Q3

12½ marks · 200 words Inclusive growth

Pradhan Mantri Jan-Dhan Yojana (PMJDY) is necessary for bringing unbanked to the institutional finance fold. Do you agree with this for financial inclusion of the poorer section of the Indian society? Give arguments to justify your opinion.

Approach · directive: “do you agree / give arguments”

What it asks · Take a position on whether PMJDY is necessary for including the poor in formal finance, backed by arguments for and against its effectiveness.

The question has 2 parts — answer each

  1. Take a clear position: is PMJDY necessary for bringing the unbanked poor into institutional finance
  2. Give arguments to justify the opinion, weighing PMJDY's strengths against its limits

Open with · Financial inclusion means timely, affordable access to basic financial services; PMJDY, launched in August 2014, aimed at a bank account for every unbanked household.

Cover

  • Agree, access: zero-balance accounts, a RuPay debit card with accident cover and later an overdraft facility brought hundreds of millions of poor people into banking.
  • Agree, delivery: with Aadhaar and mobile numbers (the JAM trinity), accounts carry direct benefit transfers of subsidies and wages and cut leakages and middlemen.
  • Agree, security: savings, remittances and linked insurance and pension products reduce dependence on moneylenders and give protection against shocks.
  • Limits: many accounts are dormant, zero-balance or duplicate, and account ownership has not always meant active use of credit, insurance or pensions.
  • Limits: poor connectivity, few business correspondents in remote areas, low financial and digital literacy, and small overdraft uptake weaken last-mile impact.
  • Alternatives: the poor also need credit and insurance; microfinance, self-help groups and small-loan schemes are complements, not substitutes, for basic accounts.
  • Way forward: link accounts to credit and insurance, expand banking outlets and digital payments, run financial literacy drives, and track active use, not only openings.

Close with · PMJDY is necessary as the base of inclusion, but it becomes sufficient only when accounts are used for savings, credit and protection.

Model answer · 277 words (UPSC limit 200) · Minimalist IAS

Financial inclusion means timely, affordable access to basic financial services. PMJDY, launched in August 2014, aimed at a bank account for every unbanked household, and it is necessary, though not sufficient, for bringing the poor into institutional finance.

Why PMJDY is necessary

  • Access: zero-balance accounts, a RuPay debit card with accident cover of Rs 1 lakh and an overdraft facility after satisfactory operation brought hundreds of millions of poor people into banking for the first time (since then, the cover is Rs 2 lakh for accounts opened after August 2018 and the overdraft limit is Rs 10,000).
  • Delivery: with Aadhaar and mobile numbers, the JAM trinity, accounts carry direct benefit transfers of subsidies, pensions and MGNREGA wages, cutting leakages and middlemen.
  • Security: savings, remittances and linked micro-insurance and pension products (PMJJBY, PMSBY, Atal Pension Yojana) reduce dependence on moneylenders and protect against shocks.
  • Entry point: an account is the first step to a credit history, digital payments and formal saving.

Limits: necessary, not sufficient

  • Many accounts are dormant, zero-balance or duplicate; ownership has not always meant active use of credit, insurance or pensions.
  • Poor connectivity, thin business-correspondent networks in remote areas, low financial and digital literacy and small overdraft uptake weaken last-mile impact.
  • The poor also need affordable credit and insurance; self-help groups, microfinance and MUDRA loans complement basic accounts rather than replace them.

Making it work

  • Link accounts to credit and insurance, expand banking outlets and digital payments, run financial literacy drives, and track active use rather than the number of openings.

PMJDY is the necessary base of financial inclusion for the poor; it becomes sufficient only when accounts are used for saving, credit and protection.

What are ‘Smart Cities’? Examine their relevance for urban development in India. Will it increase rural-urban differences? Give arguments for ‘Smart Villages’ in the light of PURA and RURBAN Mission.

Approach · directive: “what / examine / give arguments”

What it asks · Define a smart city, assess its relevance for India's urban growth, judge whether it widens the rural-urban gap, and argue for smart villages using PURA and the RURBAN Mission.

The question has 4 parts — answer each

  1. What are Smart Cities: define the concept
  2. Examine their relevance for urban development in India
  3. Will they increase rural-urban differences: give a judgement
  4. Give arguments for Smart Villages in the light of PURA and the RURBAN Mission

Open with · A smart city uses technology, data and better planning to deliver core services efficiently; India launched the Smart Cities Mission in 2015 for 100 cities (its period was later extended to March 2025).

Cover

  • Meaning: a city with adequate water, power, mobility, housing, sanitation and e-governance, run through data and citizen participation, and sustainable in its use of resources.
  • Relevance: cities generate most of the economic output and are absorbing rural migrants, so better planning and services and cleaner, compact growth are urgent.
  • Relevance: area-based projects and pan-city solutions can act as models, pull in private and municipal finance and strengthen weak urban local bodies.
  • Risk of widening gaps: investments concentrate in a few enclaves and cities, may raise land costs and displace the poor, and can pull more people from villages.
  • Smart villages: about two-thirds of Indians (68.8 per cent at the 2011 Census) lived in rural areas, and farm incomes, health, schooling and connectivity there decide whether growth is inclusive.
  • PURA and RURBAN: PURA proposed urban amenities and livelihood links in rural clusters; the Shyama Prasad Mukherji Rurban Mission (launched 2016) develops 300 growth clusters with economic activity, skills and basic services.
  • Way forward: link smart cities to their hinterlands, keep both missions fund-backed and locally led, and treat cities and villages as one economy.

Close with · Smart cities matter for India's urban future, but smart villages and rural growth clusters must be pursued alongside, so that development narrows rather than widens the gap.

Question: UPSC's CS (Main) 2016, GS Paper III — paper ↗. Approach: Minimalist IAS, checked 30 Sept 2026 (how we verify) — UPSC publishes no model answers. ·

Model answer · 298 words (UPSC limit 200) · Minimalist IAS

A smart city uses technology, data and better planning to deliver core services efficiently and sustainably. India's Smart Cities Mission, launched in 2015, selected 100 cities for area-based development and pan-city solutions (since then, the Mission period was extended to March 2025).

What smart cities are

  • Assured water, power, mobility, affordable housing, sanitation and e-governance, run through data and citizen participation, with compact, resource-efficient growth.

Relevance for urban India

  • Cities generate most economic output and absorb rural migrants, so better planning and services are urgent.
  • Retrofitting, redevelopment and greenfield projects act as models, and special purpose vehicles pull in private and municipal finance while strengthening weak urban local bodies.
  • Pan-city solutions such as intelligent transport and e-governance improve daily life at scale.

Rural-urban gap

  • Risk: investment concentrates in a few enclaves within 100 cities, may raise land prices and displace the poor, and can pull more people out of villages.
  • Balance: cities linked to their hinterland through markets and jobs can narrow the gap; the outcome depends on matching rural investment.

The case for smart villages

  • About 68.8 per cent of Indians lived in rural areas at the 2011 Census; farm incomes, health, schooling and connectivity there decide whether growth is inclusive.
  • PURA (Providing Urban Amenities in Rural Areas), proposed by Dr A.P.J. Abdul Kalam, sought physical, electronic and knowledge connectivity in rural clusters to create local livelihoods.
  • The Shyama Prasad Mukherji Rurban Mission (2016) develops 300 growth clusters with economic activity, skills and basic services, so villages gain urban amenities without losing rural character.
  • Smart villages reduce distress migration, relieve pressure on cities and widen the domestic market.

Smart cities are essential to India's urban future, but only when pursued together with smart villages and rural growth clusters will development narrow the divide rather than widen it.

What it asks · Justify why India needs foreign direct investment, explain why announced commitments in MoUs convert only partly into actual inflows, and propose steps to raise real inflows.

The question has 3 parts — answer each

  1. Justify the need for FDI for the development of the Indian economy
  2. Explain why there is a gap between MoUs signed and actual FDI
  3. Suggest remedial steps to increase actual FDI in India

Open with · FDI brings capital, technology and management along with market access; yet the announcements at investor summits are often far larger than inflows that reach the ground.

Cover

  • Need: it bridges the gap between domestic savings and investment needs and finances the current account without adding to debt.
  • Need: it brings technology, management practice, exports and jobs, deepens competition, and helps India join global value chains, especially in manufacturing and infrastructure.
  • Gap: MoUs are statements of intent, not binding contracts, and are sometimes announced for publicity or as broad, non-committal figures at investor summits.
  • Gap: delays in land acquisition, clearances and power and logistics, plus contract enforcement and tax uncertainty and disputes, make investors hold back or scale down.
  • Gap: differences between Centre and States, sectoral caps and approvals, and global conditions and financing costs also postpone projects after signing.
  • Remedies: single-window and time-bound clearances, ready land banks, stable and predictable tax rules, faster commercial dispute resolution and better contract enforcement.

Model answer · 252 words (UPSC limit 200) · Minimalist IAS

FDI brings long-term capital along with technology, management and market access. India received its highest-ever inflow of US$ 55.46 billion in 2015-16, yet the commitments announced at investor summits remain far larger than what reaches the ground.

Why India needs FDI

  • It bridges the gap between domestic savings and investment needs and finances the current account deficit without adding to external debt; it is steadier than portfolio flows.
  • It brings technology, management practice, exports and jobs, deepens competition and helps India join global value chains, especially in manufacturing (Make in India) and infrastructure.

Why MoUs do not become FDI

  • MoUs are statements of intent, not binding contracts; many are announced for publicity or as broad, non-committal figures at State investor summits.
  • Land acquisition, environmental and other clearances, power and logistics delays, tax uncertainty and slow contract enforcement make investors hold back or scale down.
  • Centre-State differences, sectoral caps and approval routes, and changes in global conditions and financing costs postpone projects after signing.

Remedial steps

  • Single-window, time-bound clearances and ready land banks with clear titles.
  • Stable, predictable tax rules with no retrospective taxation, and faster commercial dispute resolution and contract enforcement.
  • Keep liberalising: the June 2016 reforms opened defence, civil aviation, pharmaceuticals and food retail further and put most sectors on the automatic route.
  • Build infrastructure, involve States through ease-of-doing-business rankings, and track every MoU through a facilitation cell from signing to commissioning.

Credible policy, speedy clearances and reliable contract enforcement will convert MoUs into investments faster than any number of summits.

What it asks · Comment on how a workforce that is indifferent to quality and a large body of unemployed or unemployable people hold back inclusive growth, and suggest measures.

The question has 2 parts — answer each

  1. Comment on the challenges to inclusive growth, including a careless (indifferent) and useless (unemployed or unemployable) workforce
  2. Suggest measures to face these challenges

Open with · Inclusive growth needs a workforce that is skilled, healthy and engaged; without it, the demographic dividend risks turning into a burden.

Cover

  • Careless manpower: indifference and absenteeism, poor work culture and weak accountability in services lower quality and productivity and erode public trust.

Model answer · 267 words (UPSC limit 200) · Minimalist IAS

Inclusive growth is growth whose gains reach every section, chiefly through productive employment. It needs a workforce that is skilled, healthy and engaged; without one, the demographic dividend risks turning into a burden.

The manpower challenge

  • Careless manpower: indifference, absenteeism, poor work culture and weak accountability in public services and firms lower quality and productivity; absent teachers and health workers hurt the poor most.
  • Useless (unemployable) manpower: many graduates lack the skills industry needs, so open unemployment and underemployment coexist with vacancies in skilled trades, and few workers have formal vocational training.
  • Structural gaps: most workers remain in low-productivity farm and informal work, women's work participation is low, and regional and social gaps persist.
  • Root causes: weak schooling and learning outcomes, poor health and nutrition, few vocational pathways and slow growth of labour-intensive manufacturing.

Other challenges

  • Growth that creates few jobs, regional imbalance, and weak access to credit, markets and infrastructure for the poor.

Measures

  • Education and skills: raise learning outcomes, link schooling to skills, and scale Skill India, PMKVY and apprenticeships (Apprentices Act amended in 2014) with industry involvement and placement tracking.
  • Jobs: labour-intensive manufacturing and MSMEs, rural non-farm work, MGNREGA as a safety net, and more women in work through safety, transport and childcare.
  • Health and nutrition: strengthen primary care and child nutrition so that workers are fit to learn and work.
  • Accountability: citizen's charters, biometric attendance, performance-linked incentives and transparent monitoring, so that engaged workers are rewarded and carelessness is not.

Investing in health, education and skills, while rewarding effort and accountability, turns manpower from a constraint into the main engine of inclusive growth.

What is water-use efficiency? Describe the role of micro-irrigation in increasing the water-use efficiency.

Approach · directive: “what / describe”

What it asks · Define water-use efficiency and explain how drip and sprinkler systems raise it.

The question has 2 parts — answer each

  1. What is water-use efficiency: define it
  2. Describe the role of micro-irrigation (drip and sprinkler) in increasing water-use efficiency

Open with · India uses most of its freshwater for irrigation, yet gets less crop from each unit of water than many other countries; efficiency is the answer to a shrinking water budget.

Cover

  • Meaning: water-use efficiency is crop yield per unit of water used, often called more crop per drop, and judged at field, farm or project level.
  • Where it is lost: in canals and channels through seepage and evaporation, and in the field through runoff, deep percolation and excess flooding in traditional surface irrigation.
  • Drip: delivers water drop by drop to the root zone, cutting evaporation, runoff and weed growth and letting fertiliser be applied with water (fertigation).
  • Sprinklers and micro-sprinklers: spread water like rain with controlled amounts, suitable for uneven land, light soils and many field and orchard crops.
  • Gains: substantial water and energy savings, higher yield and quality, more area under irrigation from the same source, and less waterlogging and salinity.
  • Constraints: high upfront cost for small farmers, clogging, maintenance and power needs, delays in subsidy; cereals such as paddy are hard to cover.
  • Support: the Per Drop More Crop component of PMKSY (from 2015-16) provides subsidy, and NABARD's Micro Irrigation Fund (Rs 5,000 crore, created in 2018-19) helps States top up incentives for coverage.

Close with · Water-use efficiency must rise with micro-irrigation, better canal management, crop choice matched to water availability and efficient pricing of water and power.

Question: UPSC's CS (Main) 2016, GS Paper III — paper ↗. Approach: Minimalist IAS, checked 30 Sept 2026 (how we verify) — UPSC publishes no model answers. ·

Model answer · 256 words (UPSC limit 200) · Minimalist IAS

Irrigation takes most of India's freshwater, yet each unit of water yields less crop than in many countries. Water-use efficiency is the ratio of crop output to the water actually used, popularly 'more crop per drop', measured at field, farm or project level.

Where water is lost

  • Conveyance losses: seepage and evaporation from canals and field channels.
  • Application losses: runoff, deep percolation and excess flooding in traditional surface irrigation, so only part of the water reaches the root zone.
  • Efficiency rises when these losses fall and when each unit of water produces more yield.

Role of micro-irrigation

  • Drip: delivers water slowly to the root zone through emitters, cutting evaporation, runoff and deep percolation, suppressing weeds, and allowing fertigation, so nutrient use improves too.
  • Sprinklers and micro-sprinklers: spread controlled amounts of water like rain, suited to uneven land, light soils and many field, vegetable and orchard crops.
  • Gains: substantial water and energy savings, higher yield and quality, more area irrigated from the same source, and less waterlogging and salinity.
  • Support: the Per Drop More Crop component of PMKSY (2015-16) subsidises systems, with improving on-farm water-use efficiency a stated objective (since then, a Rs 5,000 crore Micro Irrigation Fund was created with NABARD in 2018-19).
  • Constraints: high upfront cost for small farmers, clogging and maintenance, power needs and delayed subsidies; cereals such as paddy are hard to cover.

Micro-irrigation is the quickest route to higher water-use efficiency, but it must go with better canal management, crop choice matched to water availability, and rational pricing of water and power.

What is allelopathy? Discuss its role in major cropping systems of irrigated agriculture.

Approach · directive: “what / discuss”

What it asks · Define allelopathy and explain its positive and negative effects on crops in irrigated cropping systems such as rice-wheat and sugarcane-based systems.

The question has 2 parts — answer each

  1. What is allelopathy: define it
  2. Discuss its role, beneficial and harmful, in major cropping systems of irrigated agriculture

Open with · Allelopathy is the effect, harmful or beneficial, of one plant on another through chemicals it releases into the environment.

Cover

  • Meaning: plants release allelochemicals through roots, leaves, residues or leachates; the term was coined by Hans Molisch in 1937; it includes effects on microbes and soil processes.
  • Weed suppression: residues and mulches of crops such as sorghum, sunflower and rye, and allelopathic rice and wheat varieties, can reduce weed growth and herbicide use.
  • Crop rotation and sequence: the effect of one crop's residue on the next explains why some rotations do well and others give lower yields.
  • Negative effects: weeds such as Parthenium and Cyperus release chemicals that reduce crop germination and growth, and tree species in agroforestry may harm associated crops.
  • Autotoxicity: repeated planting of the same crop, for example sugarcane ratoons or continuous paddy, can build up self-inhibiting chemicals and cause yield decline.

Model answer · 240 words (UPSC limit 200) · Minimalist IAS

Allelopathy is the effect, harmful or beneficial, that one plant has on another through chemicals it releases into the environment. The term was coined by Hans Molisch in 1937.

What it involves

  • Allelochemicals leave plants through root exudates, leaf leachates, volatiles and decaying residues; they affect germination, growth, soil microbes and nutrient cycling.

Beneficial role in irrigated systems

  • Weed suppression: residues and mulches of sorghum, sunflower and rye, and allelopathic rice and wheat varieties, reduce weed growth and herbicide use in rice-wheat and other intensive systems.
  • Rotation and intercropping: chemicals left by one crop shape the next, so a well-chosen sequence improves yields and pest control, and allelopathic cover crops keep weeds down in sugarcane-based systems.
  • Bio-herbicides: natural allelochemicals can replace part of the synthetic herbicides on which irrigated farming depends.

Harmful role

  • Weeds such as Parthenium and Cyperus release chemicals that reduce crop germination and vigour, and agroforestry trees can suppress crops planted beneath them.
  • Autotoxicity: continuous paddy and repeated sugarcane ratoons build up self-inhibiting compounds and cause yield decline.
  • Residues: incorporating fresh straw of some crops before it decomposes inhibits the following crop, so the timing of residue management matters.

Way forward

  • Breed allelopathic cultivars, plan rotations and intercrops, manage residues by mulching or timed incorporation rather than burning, and test effects before promotion.

Used with care, allelopathy can cut chemical use and support sustainable irrigated farming; its harmful side must be managed through rotation and residue handling.

12½ marks · 200 words Land reforms

Discuss the role of land reforms in agricultural development. Identify the factors that were responsible for the success of land reforms in India.

Approach · directive: “discuss / identify”

What it asks · Discuss how land reforms affect farm productivity and equity, and identify the conditions under which India's land reforms succeeded where they did.

The question has 2 parts — answer each

  1. Discuss the role of land reforms in agricultural development
  2. Identify the factors responsible for the success of land reforms in India

Open with · Land reform changes who owns and controls land, and so who has the incentive and security to invest in it.

Cover

  • Role: security of tenure and ownership encourage tenants to invest in irrigation, seeds and inputs, and raise productivity.
  • Role: abolition of intermediaries brought the tiller closer to the State and ended exploitation and rent-seeking by absentee landlords.
  • Role: ceilings and redistribution reduce inequality, and smaller owner-operated holdings are often more productive per hectare; consolidation and land records cut costs and disputes.
  • Success factors: abolition of intermediaries worked widely with strong political will, State backing and shelter from court challenge under Articles 31A, 31B and the Ninth Schedule.
  • Success factors: in West Bengal, Operation Barga (from 1978) recorded sharecroppers and secured them against eviction; in Kerala and West Bengal, committed governments, organised peasants and local administration made tenancy reform work.
  • Limits: tenancy reform and ceilings were diluted by loopholes, concealed tenancy, poor land records and the influence of large landowners, so much land remained concentrated.
  • Way forward: digitised land records, legal recognition of tenancy, women's land titles and land pooling or leasing for small farmers.

Close with · Where reforms had political will, legal protection and administrative machinery they raised both equity and productivity; elsewhere the unfinished agenda remains.

Model answer · 255 words (UPSC limit 200) · Minimalist IAS

Land reform changes who owns and controls land, and therefore who has the security and incentive to invest in it. After Independence India pursued abolition of intermediaries, tenancy reform, ceilings on holdings and consolidation.

Role in agricultural development

  • Security and incentive: ownership or secure tenancy encourages investment in irrigation, seeds and inputs, raising productivity.
  • Ending intermediaries: abolition of zamindari brought the tiller into direct relation with the State and ended rent-seeking by absentee landlords.
  • Equity and productivity: ceilings and redistribution reduce inequality, and owner-operated small holdings are often more productive per hectare.
  • Consolidation and records: fewer fragments and clear titles cut costs and disputes and make credit accessible.

Factors behind success

  • Political will with legal protection: the First Amendment (1951) added Articles 31A and 31B and the Ninth Schedule, shielding land reform laws from fundamental-rights challenge, so abolition of intermediaries succeeded nationwide.
  • Committed governments and organised peasants: in West Bengal, Operation Barga (from 1978) recorded sharecroppers and secured them against eviction; in Kerala, mobilised tenants and a determined government made tenancy reform effective.
  • Administrative machinery: updated land records, village-level officials and panchayat involvement in identifying tenants and surplus land.
  • Where these were absent, loopholes, concealed tenancy, benami transfers and landlord influence diluted ceilings and tenancy laws, and land stayed concentrated.

Unfinished agenda

  • Digitised land records, legal recognition of tenancy, women's land titles and land pooling or leasing for small farmers.

Land reform raised both equity and productivity wherever political will, constitutional protection and administrative capacity came together; completing that agenda remains part of agricultural development.

Given the vulnerability of Indian agriculture to vagaries of nature, discuss the need for crop insurance and bring out the salient features of the Pradhan Mantri Fasal Bima Yojana (PMFBY).

Approach · directive: “discuss / bring out”

What it asks · Explain why Indian farmers need insurance against crop loss, and list the main features of PMFBY that address the weaknesses of older schemes.

The question has 2 parts — answer each

  1. Discuss the need for crop insurance, given the vulnerability of Indian agriculture to the vagaries of nature
  2. Bring out the salient features of PMFBY

Open with · With much of the net sown area rainfed and farm incomes tied to the monsoon, one drought, flood or hailstorm can push a farming family into debt.

Cover

  • Need: weather shocks, pests and disease cause sudden income loss, small farmers lack savings, and loss often leads to debt and distress.
  • Need: insurance stabilises incomes, supports credit flow to farmers, and encourages adoption of new inputs and crops.
  • Older schemes: earlier schemes had high premiums, low coverage, capped sums insured and delayed claims; PMFBY replaced them from kharif 2016.
  • Premium: farmers pay at most 2% (kharif food and oilseeds), 1.5% (rabi) and 5% (commercial and horticultural crops); the Centre and States share the rest.
  • Coverage: prevented sowing, standing crop loss from natural risks, post-harvest losses and localised calamities such as hailstorm, landslide and inundation.
  • Technology: crop-cutting data through smartphones, remote sensing and drones to speed up assessment and claim settlement; compensation is meant to reach farmers' accounts directly.
  • Issues: delayed claims, low awareness, poor yield data and insurers' losses in bad years; the scheme is voluntary for all farmers since 2020, so participation depends on trust.

Close with · Timely and accurate yield assessment, quick claim payment and farmer awareness will decide whether PMFBY becomes a dependable shield against nature.

Model answer · 277 words (UPSC limit 200) · Minimalist IAS

Much of India's farming depends on the monsoon, and a single drought, flood or hailstorm can wipe out a season's income and push a family into debt. Crop insurance spreads that risk across farmers, insurers and the State.

Need for crop insurance

  • Weather shocks, pests and disease cause sudden income loss; small farmers have thin savings, so loss turns into debt and distress.
  • Insurance stabilises incomes, keeps credit flowing because banks lend more readily to insured farmers, and encourages adoption of new inputs and crops.
  • It is more predictable and less distorting than ad hoc relief and loan waivers.
  • Earlier schemes, NAIS and MNAIS, had high premiums, capped sums insured, low coverage and delayed claims.

Salient features of PMFBY

  • Approved in 2016 and implemented from kharif 2016, replacing NAIS and MNAIS.
  • Low, uniform premium: farmers pay at most 2 per cent for kharif food and oilseed crops, 1.5 per cent for rabi crops and 5 per cent for commercial and horticultural crops; the Centre and States share the rest without a cap, so the full sum insured is covered.
  • Comprehensive cover: prevented sowing, standing crop loss from natural risks, post-harvest losses and localised calamities such as hailstorm, landslide and inundation, the last assessed at the individual farm.
  • Technology: smartphones for crop-cutting experiments, remote sensing and drones to speed assessment, with claims paid directly into bank accounts.
  • Compulsory for loanee farmers and voluntary for others (since then, voluntary for all farmers from 2020).
  • Issues: delayed claims, low awareness, poor yield data and insurers' losses in bad years.

Timely and accurate yield assessment, quick claim payment and farmer awareness will decide whether PMFBY becomes a dependable shield against nature.

  1. Give an account: the current status of renewable energy sources in India
  2. Give an account: the targets set for renewable energy
  3. Discuss in brief: the importance of the National Programme on LEDs

Open with · India relies heavily on coal, but renewable sources and efficiency together are meant to meet rising demand while cutting emissions.

Cover

  • Status: solar and wind lead capacity additions, with solar parks and rooftop schemes; hydro is large, biomass and small hydro are smaller, and solar costs have fallen sharply.
  • Targets: in 2015 India set 175 GW of renewable capacity by 2022, of which 100 GW solar, 60 GW wind, 10 GW biomass and 5 GW small hydro.
  • Climate targets: 40% non-fossil power capacity by 2030 (2015 pledge); at Glasgow in 2021, 500 GW non-fossil capacity by 2030 and net zero by 2070.
  • Enablers and gaps: the International Solar Alliance, green energy corridors and storage; challenges are land, grid integration, finance, DISCOM health and intermittency.
  • LED programme: launched in January 2015 to replace inefficient bulbs, with a target of about 77 crore incandescent lamps, later run as UJALA through EESL.
  • Importance: an LED uses far less power than an incandescent bulb, cutting peak demand, household bills and emissions, and lasts much longer.
  • Method: bulk purchase and pay-as-you-save lowered LED prices sharply, so an efficiency programme paid for itself without heavy subsidy; a street-lighting programme followed.

Close with · Energy efficiency through LEDs and clean supply through renewables together lower emissions and cost, and both are needed for energy security.

Model answer · 299 words (UPSC limit 200) · Minimalist IAS

India still generates most of its electricity from coal, but renewables and efficiency are now planned together to meet rising demand at lower emissions. By October 2016 the MNRE reported 46.33 GW of grid-connected renewable capacity, about 15% of the country's 307 GW total.

Current status

  • Wind holds the largest share of renewable capacity, and India stands fourth in the world in installed wind power (2016).
  • Solar is the fastest-growing segment as tariffs fall: solar parks, canal-top plants, rooftop systems and solar pumps; small hydro exceeds 4.3 GW, while biomass and waste-to-energy remain small.
  • Enablers: the International Solar Alliance launched in 2015, green energy corridors for evacuating power, and renewable purchase obligations on DISCOMs.
  • Gaps: land, grid integration and storage for intermittent power, finance, and weak DISCOMs that must buy the power.

Targets

  • 175 GW of renewable capacity by 2022, set in 2015: 100 GW solar, 60 GW wind, 10 GW biomass and 5 GW small hydro.
  • Climate pledge (INDC, 2015): 40% of installed power capacity from non-fossil sources by 2030 (since then, raised at Glasgow in 2021 to 500 GW of non-fossil capacity by 2030, with net zero by 2070).

Importance of the National LED Programme

  • Launched on 5 January 2015, later branded UJALA and run by EESL, it aims to replace about 77 crore incandescent bulbs.
  • A 7 W LED gives the light of a 60 W incandescent bulb, saving nearly 90% of the energy; it lasts far longer and cuts household bills, peak demand and emissions.
  • Bulk procurement cut LED prices steeply, and pay-as-you-save instalments through electricity bills meant no heavy subsidy; a street-lighting programme followed on the same model.

Cleaner supply through renewables and lower demand through LEDs are two halves of one strategy; together they cut cost and emissions and strengthen India's energy security.

From the first satellite Aryabhata to the Mars Orbiter Mission, ISRO has built a self-reliant, low-cost space programme whose declared purpose has always been national development rather than prestige alone.

Achievements in space science and technology

  • Launch vehicles: from SLV-3 to the PSLV workhorse and the GSLV; the indigenous cryogenic upper stage flew successfully on GSLV-D5 in January 2014, and the heavier GSLV Mk III is under development.
  • Satellites: the INSAT/GSAT communication series, the IRS remote-sensing fleet, the seven-satellite IRNSS (NavIC) regional navigation system completed in 2016, and Astrosat (2015), India's first multi-wavelength observatory.
  • Science missions: Chandrayaan-1 (2008) found evidence of water on the Moon; the Mars Orbiter Mission entered Mars orbit in September 2014 on India's first attempt and at a modest budget.
  • Technology and commerce: the reusable launch vehicle demonstrator flew in May 2016, and PSLV launches foreign satellites through Antrix (since then, 104 satellites in one launch in February 2017 and the Chandrayaan-3 landing near the lunar south pole in 2023).

Applications in socio-economic development

  • Communication: INSAT/GSAT transponders carry telephony, television and DTH to remote areas; tele-education links classrooms to expert teachers and telemedicine links district hospitals to specialists.
  • Agriculture and resources: crop-area and yield forecasting, groundwater prospect maps, watershed and land-use planning, and potential fishing zone advisories that raise catch and save fuel.
  • Disaster management: INSAT weather data and cyclone tracking enabled mass evacuation before cyclone Phailin in 2013; satellites map floods, droughts and forest fires for relief.
  • Navigation and transport: NavIC for vehicle tracking, fishing and defence, and GAGAN for safer civil aviation.
  • Governance: imagery for land records, urban planning and geo-tagging of MGNREGA assets, shared through the Bhuvan geoportal.

India's space programme pairs frontier science with everyday services in classrooms, farms and cyclone shelters: space as an instrument of development, not only of pride.

Nanotechnology engineers matter at 1 to 100 nanometres, where materials acquire new strength, conductivity, reactivity and optical behaviour that bulk matter does not show.

Why a key technology

  • Scale changes properties: carbon nanotubes are stronger than steel yet light, silver nanoparticles kill microbes, nano-catalysts react faster; materials can be designed atom by atom.
  • General-purpose reach: targeted drugs and sensitive diagnostics, better solar cells and batteries, smaller and faster chips, membranes for water, and inputs for agriculture.
  • Convergence: it fuses with biotechnology, information technology and materials science; the countries that lead it gain in manufacturing, health and defence.

Nano Mission: salient features

  • Launched by the Department of Science and Technology in May 2007 with Rs 1,000 crore for five years, as an umbrella programme for capacity building in nanoscience and nanotechnology.
  • Basic research: grants to individual scientists and research units in nanoscience.
  • Infrastructure: centres of excellence and shared facilities for synthesis, characterisation and fabrication, open to institutions nationwide.
  • Applications and technology development through joint institution-industry projects, with promotion of public-private partnership.
  • Human resource development through postgraduate programmes, fellowships and training, plus international collaboration and public awareness of nanoscience.

Scope in India's development

  • Water: nano-membranes and nanoparticle filters to remove arsenic, fluoride and pathogens from rural drinking water cheaply.
  • Health: cheap point-of-care diagnostic kits and targeted delivery of drugs for tuberculosis and cancer, cutting dose and side effects.
  • Agriculture: nano-fertilisers and pesticides that cut input use, and smart packaging that reduces post-harvest loss.
  • Energy, environment and industry: efficient solar cells, LEDs and catalysts, pollution sensors, and lighter, stronger composites, coatings, textiles and cement.
  • Caution: nanoparticles can be toxic to people and ecosystems, and standards lag; safety research and regulation must grow with applications.

Nanotechnology can serve India's goals in water, health and energy if the Nano Mission's research is carried into safe, affordable products, with regulation keeping pace.

What it asks · Discuss the measures that reduce the harm of displacing people for big dams, mines and industries, covering planning, compensation, resettlement and monitoring.

The question has 2 parts — answer each

  1. Establish: why rehabilitation of displaced settlements attracts controversy in major projects
  2. Discuss: the measures suggested to mitigate this impact while proposing major developmental projects

Open with · Large projects can displace communities and destroy livelihoods; the environment includes people, so resettlement is part of impact assessment.

Cover

  • Avoid and minimise: consider alternative sites and designs, keep the footprint small, and prefer options that displace fewer people, especially avoiding Scheduled Areas.
  • Assess early: environmental and social impact assessment with public hearings and consultation with gram sabhas and affected families before clearance.
  • Legal framework: the 2013 land acquisition, rehabilitation and resettlement law (RFCTLARR Act) requires a social impact assessment and prescribes prior consent for private and PPP projects.
  • Rehabilitation package: land for land or livelihood support, houses with civic amenities, skills and jobs, subsistence allowance and protection of community property, sacred sites and culture.
  • Fair process: timely compensation, special care for tribal and vulnerable groups, women's names on titles, and a grievance and monitoring mechanism, including independent audit.
  • Benefit sharing: give affected families a share in project benefits, such as employment, royalty or equity, and complete resettlement before submergence or eviction.
  • Past lessons: delayed resettlement, unpaid compensation and neglect of host communities at dam and mining sites explain the controversy.

Model answer · 304 words (UPSC limit 200) · Minimalist IAS

Large dams, mines and industrial projects displace whole settlements, and the environment they alter includes people and livelihoods; the Sardar Sarovar project shows how unresolved rehabilitation keeps a project in dispute for decades.

Why rehabilitation is controversial

  • Displaced families lose land, common property and cultural ties, and rehabilitation has often lagged years behind submergence or eviction.
  • Cash compensation to landowners leaves out the landless, tenants, artisans and forest dwellers; tribal communities in Scheduled Areas bear a disproportionate share of displacement.
  • Host communities and lost social networks are ignored, breeding distrust and litigation.

Measures suggested for mitigation

  • Avoid and minimise: examine alternative sites, designs and dam heights to shrink the footprint, and steer clear of Scheduled Areas and densely settled land where possible.
  • Assess early and openly: a Social Impact Assessment alongside the environmental impact assessment, with public hearings and consultation of gram sabhas, mandatory under PESA before acquisition in Scheduled Areas.
  • Consent and entitlements: the RFCTLARR Act, 2013 requires the prior consent of affected families for private and PPP projects and extends rehabilitation to those who lose livelihoods, not only land.
  • Resettlement as a package: land for land where feasible, houses with roads, water, schools and health centres, skills and jobs, subsistence allowance, and protection of community assets and sacred sites.
  • Fair process: compensation and resettlement completed before eviction or submergence, titles in the names of both spouses, and special care for Scheduled Tribes and vulnerable groups.
  • Benefit sharing: employment, annuity or a stake in the project for affected families, so they gain from development rather than pay for it.
  • Institutions: a rehabilitation authority, grievance redressal, independent monitoring and social audit, with attention to host communities.

Displacement cannot always be avoided, but projects that avoid it where possible, involve affected people in decisions and restore livelihoods before construction make development fairer and less contested.

What it asks · Explain why cities are flooding more often after intense rain, then set out the preparedness measures that reduce loss of life and property.

The question has 2 parts — answer each

  1. Discuss: the reasons for the increasing frequency of urban floods
  2. Highlight: the preparedness mechanisms to reduce risk during such events

Open with · Cities such as Mumbai in 2005 and Chennai in 2015 showed that heavy rain turns into a disaster when drains, lakes and floodplains are lost to construction.

Cover

  • Natural causes: more intense short-duration rain linked to climate change, the urban heat island effect, cyclones and storm surge in coastal cities, and high tides blocking outfalls.
  • Land use: encroachment on lakes, wetlands, floodplains and drains, and paved surfaces that cut infiltration and speed up run-off.
  • Infrastructure: drains designed for low rainfall, silted, clogged with waste or missing, weak maintenance, and sudden dam or reservoir releases upstream.
  • Governance: multiple agencies working separately, weak enforcement of building norms and master plans, and no local flood-risk mapping.
  • Preparedness, forecasting: flood-risk mapping and zoning, Doppler radar and rain-gauge networks, IMD nowcasts and warnings, and a coordination protocol with dam operators.
  • Preparedness, systems: drainage master plans, drain desilting before monsoon, restoration of lakes and wetlands, and green measures such as rain gardens, permeable pavements and harvesting.
  • Preparedness, response: early warning to citizens, control rooms, SOPs with trained response forces, shelters, evacuation routes, insurance and public education, as NDMA's 2010 urban flooding guidelines urge.

Close with · Making room for water through restored wetlands, better drains and land-use control, backed by early warning, is the surest way to cut urban flood risk.

Model answer · 303 words (UPSC limit 200) · Minimalist IAS

Mumbai in 2005 and Chennai in 2015 showed that heavy rain becomes a disaster when a city builds over its drains, lakes and floodplains; NDMA's 2010 guidelines treat urban flooding as a distinct hazard.

Reasons for urban floods

  • Climate: more intense short-duration rainfall, convective downpours over the urban heat island, and in coastal cities storm surge and high tides that block outfalls.
  • Land use: encroachment on lakes, wetlands, floodplains and natural drains, and paved surfaces that stop infiltration and speed run-off.
  • Drainage: storm drains built for low rainfall, silted, clogged with waste, mixed with sewage and rarely maintained.
  • Upstream releases: sudden discharge from reservoirs without warning downstream, as in Chennai in 2015.
  • Governance: many agencies with no single flood authority, weak enforcement of master plans and building norms, and no local flood-risk maps.

Preparedness mechanisms

  • Know the risk: ward-level flood hazard mapping and zoning, Doppler weather radars and dense automatic rain gauges, and IMD nowcasts turned into city-specific warnings.
  • Protocols: reservoir operation rules with advance warning before releases, a single nodal authority for urban floods, and an incident response system fixing who does what.
  • Drains and water bodies: drainage master plans using updated rainfall data, pre-monsoon desilting, separation of sewage from storm water, and restoration of lakes and wetlands.
  • Sponge measures: rain gardens, permeable pavements, rainwater harvesting and protected green spaces that make room for water.
  • Response readiness: early warning by SMS and media, control rooms, standard operating procedures, trained municipal and SDRF/NDRF teams, pumps, identified shelters and evacuation routes, and protection of hospitals and power supply.
  • Community and finance: ward volunteers, mock drills, public education and flood insurance, with enforcement action after every event.

Making room for water through restored wetlands, better drains and land-use control, backed by early warning and trained responders, is the surest way to cut urban flood risk.

With reference to National Disaster Management Authority (NDMA) guidelines, discuss the measures to be adopted to mitigate the impact of the recent incidents of cloudbursts in many places of Uttarakhand.

Approach · directive: “discuss”

What it asks · Discuss measures for reducing loss from cloudbursts in the fragile Uttarakhand Himalaya, in line with NDMA's guidelines on floods and landslides.

The question has 2 parts — answer each

  1. Explain: cloudbursts and why they cause such damage in Uttarakhand
  2. Discuss, with reference to NDMA guidelines: the measures to mitigate the impact of cloudbursts

Open with · A cloudburst is a sudden, very heavy fall of rain over a small area, and in steep hills it triggers flash floods and landslides, as at Kedarnath in 2013.

Cover

  • Hazard: IMD describes a cloudburst as rainfall of about 10 cm (100 mm) or more in an hour over roughly 20-30 sq km; steep slopes and loose debris magnify its effect.
  • Hazard mapping: landslide and flash-flood zonation at village scale, mapping of streams, and marking of unsafe sites, with maps used in planning and permissions.
  • Regulation: no building in river beds, flood plains and steep unstable slopes; hill-specific building codes; controlled road, hydropower and tourism projects and safe disposal of muck.
  • Early warning: more automatic weather stations and radar, rainfall thresholds and timely alerts to villagers and pilgrims through local channels and mobile alerts.
  • Structural and eco measures: slope stabilisation with bio-engineering, retaining walls, drainage and check dams, and afforestation with native species on catchments.
  • Preparedness and response: community-based disaster plans and volunteers, mock drills, trained SDRF and NDRF units, safe shelters, communication links and stock of relief.
  • Recovery: rebuild safer, relocate vulnerable settlements, offer insurance and livelihood support, and monitor implementation of recommendations after each disaster.

Close with · In the Himalaya safety depends on where and how we build; hazard maps, regulation, warning and trained communities together reduce the damage from cloudbursts.

Model answer · 301 words (UPSC limit 200) · Minimalist IAS

A cloudburst is a sudden fall of very heavy rain, about 100 mm or more within an hour over a small area of 20-30 sq km, which in Uttarakhand's steep, debris-laden valleys turns into flash floods and landslides, as at Kedarnath in June 2013 and in Pithoragarh and Chamoli in July 2016.

Why the damage is so high

  • Cloudbursts cannot yet be forecast precisely, so losses depend on where and how people build: on river terraces and unstable slopes, along pilgrim routes, with road cutting and hydropower muck adding loose debris to swollen streams.

Measures in line with NDMA guidelines

  • Hazard zonation: village-scale landslide and flash-flood zonation, mapping of streams, glacial lakes and unstable slopes, with the maps binding on land-use plans and building permissions.
  • Regulation: no construction in river beds, floodplains and on unstable slopes; hill-specific building codes; controlled road, hydropower and tourism projects with safe muck disposal; carrying-capacity limits on pilgrim traffic.
  • Early warning: dense automatic weather stations and Doppler radars, rainfall thresholds that trigger alerts, and last-mile dissemination to villages and pilgrims through sirens, mobile alerts and local channels.
  • Structural and ecological: slope stabilisation, retaining walls, drainage and check dams, bio-engineering and afforestation with native species on catchments, and natural stream channels kept clear.
  • Preparedness and response: community-based disaster plans and trained village volunteers, mock drills, SDRF and NDRF units pre-positioned during the monsoon, safe shelters, satellite phones and helipads for evacuation, and stocked relief.
  • Recovery: build back safer, relocate settlements from high-risk sites, insurance and livelihood support, and follow-up on the recommendations of every post-disaster review, which NDMA's guidelines on floods and on landslides both stress.

In the Himalaya safety lies in where and how we build; hazard maps, enforced regulation, timely warning and trained communities together turn a cloudburst from a catastrophe into a manageable event.

The terms Hot Pursuit and ‘Surgical Strikes’ are often used in connection with armed action against terrorist attacks. Discuss the strategic impact of such actions.

Approach · directive: “discuss”

What it asks · Explain the two terms and discuss what cross-border counter-terror actions achieve strategically and what risks and limits they carry.

The question has 2 parts — answer each

  1. Explain: the terms hot pursuit and surgical strikes
  2. Discuss: the strategic impact of such actions, with their gains, risks and limits

Open with · Hot pursuit means following attackers across a border immediately after an attack; a surgical strike is a limited, precise operation against a known target, such as the LoC action of September 2016.

Cover

  • Meaning: hot pursuit is chasing attackers across a border straight after an attack; a surgical strike is a planned, targeted action with limited scope and low collateral damage.
  • Strategic gains: they impose costs on terror groups and their sponsors, signal resolve, restore public confidence and raise the morale of security forces.
  • Doctrinal shift: they show willingness to act beyond strategic restraint, and they may deter by raising the risk of retaliation for future attacks.
  • Risks: escalation between nuclear-armed neighbours, denial and retaliation by the other State, and reputational costs if facts are contested.
  • Law: hot pursuit is recognised at sea (UNCLOS Article 111), not on land; some States argue that self-defence allows action where the other State is unable or unwilling to act, a contested view.
  • Limits: such actions damage launch pads and camps but do not end sponsorship; terror groups regroup, so they are a supplement to defence, intelligence and diplomacy.
  • Way forward: pair calibrated force with better intelligence, border defence, financial pressure through global forums and diplomacy that isolates sponsors.

Close with · Cross-border strikes can raise the cost of terrorism for its sponsors, but lasting security needs a mix of force, defence, intelligence and diplomacy.

  • The UN Charter recognises a State's inherent right of self-defence against an armed attack, the legal basis on which cross-border counter-terror action is usually justified. Charter of the United Nations, Article 51 — United Nations ↗“Nothing in the present Charter shall impair the inherent right of individual or collective self-defence if an armed attack occurs against a Member of the United Nations, until the Security Council has taken measures necessary to maintain international peace and security.”

Model answer · 286 words (UPSC limit 200) · Minimalist IAS

Hot pursuit is the immediate chase of attackers across a border, as in the June 2015 operation against insurgent camps along the Myanmar border; a surgical strike is a planned, precise action against a specific target with limited scope and collateral damage, as in the strikes across the Line of Control in September 2016 after the Uri attack.

Strategic gains

  • Imposing cost: the burden of an attack shifts back to the perpetrators and their sponsors, ending the assumption that India will always show restraint.
  • Signalling: political will and military capability are demonstrated, raising the morale of forces and public confidence; a calibrated, publicly announced action also signals its limits.
  • Space below the nuclear threshold: punitive action without full-scale war shows that nuclear blackmail cannot shield cross-border terrorism.
  • Diplomacy: framing the action as self-defence, the inherent right under Article 51 of the UN Charter, and briefing foreign envoys helps isolate the sponsor.

Risks and limits

  • Escalation: retaliation, artillery duels and heavier infiltration between nuclear-armed neighbours; misperception can spiral.
  • Law: hot pursuit is recognised at sea under UNCLOS Article 111, not on land, and the 'unable or unwilling' view of self-defence is contested, so each action needs tight justification.
  • Denial: the target State denies the action, which blunts the message and invites propaganda when facts are contested.
  • Limited effect: strikes destroy launch pads, not the infrastructure of sponsorship; groups regroup, so such actions supplement border defence, intelligence and diplomacy rather than replace them.
  • Politicisation: using operations for domestic politics can erode the credibility of the security establishment.

Cross-border strikes raise the cost of terrorism and restore deterrence, but their effect lasts only when backed by strong border defence, intelligence, financial pressure on sponsors and diplomacy that isolates them.

“Terrorism is emerging as a competitive industry over the last few decades.” Analyze the above statement.

Approach · directive: “analyze”

What it asks · Analyse how terror groups increasingly behave like competing organisations, with funding, recruitment, branding and rivalry, and what follows for counter-terrorism.

The question has 2 parts — answer each

  1. Analyse: how terrorism has come to behave like a competitive industry, in funding, supply, recruitment, branding and rivalry
  2. Analyse: what follows for counter-terrorism, and the limits of the industry analogy

Open with · Terrorism has grown from small groups with a cause into networks with budgets, supply chains and competition for recruits, funds and attention.

Cover

  • Funding: terror groups raise money through extortion, kidnapping, smuggling, narcotics, illegal mining or oil, donations and criminal enterprises, and move it by hawala and crypto assets.
  • Organised crime nexus: arms, fake currency, drug and human trafficking networks supply and finance terror, which blurs the line between crime and ideology.
  • Competition: groups outbid each other with bigger, more visible attacks to win recruits, funds and sponsors; al-Qaeda and ISIS rivalry is an example.
  • Branding and franchising: affiliates use a common name and message, and social media is used for marketing, propaganda and recruitment, including of lone actors.
  • State sponsorship and professional support: use of terror as a low-cost proxy, provision of training, safe havens and weapons, and paid or skilled operatives.
  • Response: cut finances through financial intelligence and international norms, tighten borders, prosecute crime networks, counter online radicalisation and isolate sponsors.
  • Limits of the analogy: ideology, grievance and identity still drive many groups, so counter-radicalisation and development remain necessary.

Close with · If terror behaves like an industry, the counter must target its funds, supply lines and recruitment, and also the ideas that give it demand.

Model answer · 303 words (UPSC limit 200) · Minimalist IAS

Terror groups today run budgets, supply chains, brands and recruitment drives, competing with one another for money, members and media attention much as firms compete for markets.

Terrorism as a competitive industry

  • Revenue streams: extortion, kidnapping for ransom, narcotics, smuggling, illegal mining and oil sales, as by ISIS in Syria and Iraq, and charity and diaspora donations moved through hawala, shell companies and virtual currencies.
  • Supply chain: arms, explosives, fake currency, forged documents and safe houses sourced from organised crime; the 1993 Mumbai blasts, run through smuggling networks, are India's own example of the crime-terror nexus.
  • Competition: groups outbid one another in spectacle to attract recruits and sponsors; the rivalry between al-Qaeda and ISIS after 2014 saw affiliates switch to the stronger brand.
  • Branding and franchising: a global name, a media wing, online magazines and social media market the cause to lone actors, while local groups adopt the franchise for legitimacy.
  • Labour and capital: paid trainers, bomb-makers and hackers, foreign fighters drawn by salaries and status, and State sponsors who invest in proxies as a low-cost instrument of policy.

Implications for counter-terrorism

  • Attack the finances: FATF standards, the Prevention of Money Laundering Act, financial intelligence units, and tracking of hawala and crypto flows.
  • Break the supply chain: dismantle crime networks through the NIA and state police, and tighten border and coastal security.
  • Counter the brand: take down propaganda, build counter-narratives, de-radicalisation and community policing.
  • Deny sponsors: UN listing of groups and individuals, sanctions and diplomatic isolation of sponsoring States.

Limits of the analogy

  • Ideology, grievance and identity, not profit, still drive many groups; a market view alone misses the political roots that justice, development and dialogue must address.

If terrorism behaves like an industry, counter-terrorism must cut off its capital, supply lines and recruitment, while also draining the grievances that create its demand.

Border management is a complex task due to difficult terrain and hostile relations with some countries. Elucidate the challenges and strategies for effective border management.

Approach · directive: “elucidate”

What it asks · Explain the terrain, political and security challenges along India's land and coastal borders and the strategies that can make border management effective.

The question has 2 parts — answer each

  1. Elucidate: the challenges of border management arising from difficult terrain and hostile relations
  2. Elucidate: the strategies for effective border management

Open with · India has over 15,000 km of land border with seven neighbours and a long coastline, and every stretch presents a different problem of terrain, politics and crime.

Cover

  • Terrain: high Himalayan heights, deserts, marshes and creeks, riverine and forested tracts make fencing, patrolling and surveillance difficult and costly.
  • Politics and disputes: unsettled boundaries such as the Line of Actual Control, hostile relations with some neighbours, and hostile actors using the border for infiltration.
  • Illegal movement: cross-border terrorism, smuggling of arms, drugs and fake currency, human trafficking, illegal migration and insurgent camps across the border, in some places an open border.
  • Institutional gaps: several forces and agencies with overlapping roles, gaps in coordination and intelligence sharing, thin infrastructure and manpower and slow work on roads and fences.
  • Strategies, physical: fencing, floodlighting, roads and border outposts, integrated check posts, and technology under an integrated border management system: sensors, radars, drones and cameras.
  • Strategies, institutional: clear force-to-border responsibility (BSF, ITBP, SSB, Assam Rifles, Coast Guard), joint intelligence, and specialised training for each terrain.
  • Strategies, people and diplomacy: development of border areas and villages to give locals a stake, dialogue and boundary settlement, such as the land boundary agreement with Bangladesh (1974 agreement, 2011 protocol, implemented in 2015).

Close with · Effective border management combines technology, infrastructure and clear command with development of border areas and steady diplomacy.

Model answer · 306 words (UPSC limit 200) · Minimalist IAS

India shares over 15,000 km of land border with seven neighbours, including 4,097 km with Bangladesh, 3,488 km with China and 3,323 km with Pakistan, plus a coastline of over 7,500 km; each stretch mixes hard terrain with hard politics.

Challenges

  • Terrain: Himalayan heights and glaciers, the Thar desert, the Rann's marshes and creeks, the riverine Sundarbans and the forested north-eastern hills make fencing, patrolling and surveillance costly and porous.
  • Hostile and unsettled borders: infiltration and ceasefire violations on the Line of Control, an undemarcated Line of Actual Control, and porous borders with Bangladesh and Myanmar; the 2008 Mumbai attack came by sea.
  • Cross-border crime: terrorism, arms, drugs from the Golden Crescent and Golden Triangle, fake currency, cattle and human trafficking, illegal migration and insurgent camps across the Myanmar border.
  • Institutional gaps: overlapping roles of several forces, weak intelligence sharing, thin roads and manpower, and slow land acquisition for fences.

Strategies

  • One border, one force: BSF on the Pakistan and Bangladesh borders, ITBP on China, SSB on Nepal and Bhutan, Assam Rifles on Myanmar, and the Coast Guard with marine police at sea, each with clear accountability.
  • Infrastructure and technology: fencing, floodlighting, outposts, roads and integrated check posts, with sensors, radars, thermal imagers and drones for riverine gaps where fencing fails.
  • Intelligence and coordination: joint intelligence through the Multi-Agency Centre, coastal radar chains and transponders on fishing boats, and terrain-specific training.
  • People: the Border Area Development Programme for roads, health and schools, so border villagers become the eyes and ears of security forces.
  • Diplomacy: settle boundaries, as the Land Boundary Agreement with Bangladesh did (1974 agreement, 2011 protocol, implemented in 2015), and institutionalise border-guard talks and coordinated patrols with China and Myanmar.

Effective border management combines clear command, technology and infrastructure with development of border areas and steady diplomacy that turns hostile borders into managed ones.

Use of Internet and social media by non-state actors for subversive activities is a major security concern. How have these been misused in the recent past? Suggest effective guidelines to curb the above threat.

Approach · directive: “how / suggest”

What it asks · Describe how terrorists, insurgents and other non-state actors have misused the internet and social media, and suggest guidelines that reduce the threat without harming freedom of speech.

The question has 2 parts — answer each

  1. How: the internet and social media have been misused by non-state actors in the recent past
  2. Suggest: effective guidelines to curb the threat without harming free speech

Open with · The internet lets small groups reach millions cheaply and anonymously, which suits propaganda, recruitment, coordination and rumour as much as it suits ordinary users.

Cover

  • Misuse, radicalisation: propaganda videos, online recruitment and grooming of young people by terror groups such as ISIS, including through encrypted messaging apps.
  • Misuse, rumours and hate: fake news and doctored videos that incite panic and communal violence, as in the 2012 exodus of northeast people from some cities.
  • Misuse, mobilisation and crime: coordination of protests and violence, funding through crowdfunding and crypto assets, arms and drug trade on the dark web, and cyber attacks and hacking.
  • Legal tools: the Information Technology Act, 2000, including blocking under section 69A with safeguards, monitoring and interception, and the Unlawful Activities (Prevention) Act.
  • Guidelines, platforms: due diligence, quick takedown and grievance redressal by intermediaries, cooperation on user information, and transparency, as in the 2021 IT Rules.
  • Guidelines, capacity: strong cyber units, CERT-In and a national cyber crime coordination centre, monitoring of extremist content and counter-narratives, and digital literacy.
  • Safeguards: any restriction must be lawful, necessary and proportionate, since free speech can be restricted only on the grounds listed in Article 19(2).

Model answer · 303 words (UPSC limit 200) · Minimalist IAS

The internet lets a handful of people reach millions cheaply and anonymously, which serves propaganda, recruitment and rumour as readily as it serves commerce and education.

Misuse in the recent past

  • Radicalisation and recruitment: ISIS used videos, online magazines and encrypted messaging apps to draw recruits, including a few Indian youth.
  • Rumour and communal violence: in 2012 doctored images and mass messages triggered the exodus of north-eastern people from Bengaluru and other cities; a fake video helped ignite the 2013 Muzaffarnagar riots.
  • Mobilisation: separatist groups use social media to organise stone-pelting and protests, as in Kashmir in 2016.
  • Crime and finance: crowdfunding and virtual currencies for terror funds, dark-web markets for arms and drugs, defacement of government websites, and honey-trapping of defence personnel for espionage.

Guidelines to curb the threat

  • Law: apply the IT Act, 2000, with blocking under section 69A and the safeguards upheld in Shreya Singhal (2015), which struck down the vague section 66A; use the UAPA against terror content.
  • Platforms: due diligence by intermediaries, time-bound takedown on lawful orders, grievance officers and cooperation on user data through mutual legal assistance (since then, the IT Rules, 2021 codified these duties).
  • Capacity: a national cyber crime coordination centre, CERT-In, cyber cells and forensic labs in every state police, and social media monitoring to detect rumours early.
  • Counter-narrative: credible official information during crises, engagement with community leaders, and de-radicalisation programmes for returnees and sympathisers.
  • Awareness and cooperation: digital literacy to verify before forwarding, and international cooperation on servers and evidence located abroad.
  • Safeguards: every restriction must fall within Article 19(2), be necessary and proportionate, and face judicial or independent oversight; blanket internet shutdowns should be the rare exception.

Security and freedom online can coexist when clear law, accountable platforms, trained agencies and an informed public work together against those who exploit the medium.
