GS Paper III 2022 · Q1

10 marks · 150 words Infrastructure

Why is Public Private Partnership (PPP) required in infrastructural projects ? Examine the role of PPP model in the redevelopment of Railway Stations in India.

Approach · directive: “why / examine”

What it asks · Explain why infrastructure needs private participation (finance, efficiency, risk sharing) and assess how the PPP model has worked in redeveloping railway stations.

The question has 2 parts — answer each

  1. Why: explain the need for Public Private Partnership in infrastructure projects — finance, efficiency, risk sharing
  2. Examine: how the PPP model has worked in redeveloping railway stations — the model, progress and problems

Open with · India's infrastructure gap is far larger than public budgets alone can fill, so PPP brings private capital, technology and management discipline into public assets.

Cover

  • Why PPP: a large financing gap, limited fiscal space, faster delivery, better lifecycle maintenance, and sharing of construction and demand risk.
  • Other gains: private technology and managerial efficiency, user-pay revenue, and public funds freed for social sectors.
  • Station model: a private developer redevelops the station and recovers cost by commercial use of surplus land and air space on long leases.
  • Progress: Rani Kamalapati (Habibganj) station, Bhopal, dedicated in November 2021, was redeveloped in PPP mode as a green building with modern amenities.
  • Challenges: thin bidder interest outside big cities, delays in land and approvals, uncertain commercial returns and slow progress against targets.
  • Safeguards: transparent concession terms, regulated user charges, passenger-facility standards, dispute resolution and independent monitoring.
  • Since then: the Amrit Bharat Station Scheme (2023) identified 1,275 stations for phased development, widening redevelopment beyond the PPP route.

Close with · PPP works when risks are shared fairly and returns are bankable; Railways must protect public-interest standards while private capital brings speed and scale.

Model answer · 246 words (UPSC limit 150) · Minimalist IAS

India's infrastructure needs run far ahead of what public budgets can fund, so Public Private Partnership (PPP) brings private capital, technology and managerial discipline into public assets while the government keeps ownership and sets the standards.

Why PPP is required

  • Fiscal space: limited budgets and competing social claims mean private finance is needed to close the infrastructure gap faster.
  • Efficiency: private operators bring technology, lifecycle maintenance and performance-linked payments that departmental execution often lacks.
  • Risk sharing: construction, cost-overrun and demand risks go to the party best able to manage them, with user charges creating a revenue stream.
  • Public funds freed for health and education, while projects move faster and at scale.

PPP in station redevelopment

  • Model: a private developer rebuilds the station and its multimodal links and recovers cost by commercial use of surplus land and air space on a long lease; Railways retains ownership.
  • Progress: Rani Kamalapati (Habibganj) station, Bhopal, dedicated in November 2021, was redeveloped in PPP mode as a green building with world-class amenities.
  • Limits: thin bidder interest outside big cities, uncertain commercial returns, delays in land and approvals and slow progress against targets (since then, the Amrit Bharat Station Scheme of 2023 has identified 1,275 stations for phased development).
  • Safeguards: transparent concession terms, regulated user charges, passenger-facility standards, dispute resolution and independent monitoring.

PPP works when risks are shared fairly and returns are bankable; Railways must keep passenger standards and affordability in its own hands while private capital brings speed and scale.

Is inclusive growth possible under market economy ? State the significance of financial inclusion in achieving economic growth in India.

Approach · directive: “is / state”

What it asks · Argue whether markets alone can deliver inclusive growth, and explain how financial inclusion supports growth in India.

The question has 2 parts — answer each

  1. Is inclusive growth possible under a market economy: take a clear position and qualify it
  2. State the significance of financial inclusion for achieving economic growth in India

Open with · Markets allocate resources efficiently, but efficiency is not equity; inclusion has to be built into the rules, institutions and public services around the market.

Cover

  • Yes, conditionally: competition, jobs and enterprise raise incomes; post-1991 growth reduced poverty, but gains were uneven across regions, sectors and classes.
  • Markets alone fail: they under-provide public goods, ignore the poor's lack of assets and skills, and can concentrate wealth and power.
  • What makes growth inclusive: public investment in health, education and skills, social protection, progressive taxation, labour-intensive growth and regulation of monopoly.
  • Financial inclusion: Jan Dhan accounts, Aadhaar and mobile (JAM), UPI, direct benefit transfer, micro-insurance and pensions bring the excluded into the formal system.
  • Link to growth: it mobilises household savings, reduces dependence on moneylenders, gives credit to MSMEs, women and farmers, and cuts leakages in subsidies.
  • Gaps: dormant accounts, thin credit to small borrowers, the digital and literacy divide and weak grievance redress; inclusion must mean usage, not only access.

Close with · The market is a good engine but not a steering wheel; a supportive State and wide financial access make growth inclusive.

Model answer · 216 words (UPSC limit 150) · Minimalist IAS

Markets allocate resources efficiently, but efficiency is not equity: who gains from growth depends on the rules, institutions and public services built around the market.

Inclusive growth under a market economy

  • Possible, but not automatic: competition, enterprise and jobs after 1991 raised incomes and cut poverty, yet the gains were uneven across regions, sectors and classes.
  • Markets alone exclude: they under-provide public goods, bypass those without assets, skills or credit, and can concentrate wealth and market power.
  • Inclusion is engineered: public investment in health, education and skills, social protection, progressive taxation, labour-intensive growth and competition regulation, as the Directive Principles (Articles 38 and 39) direct.

Significance of financial inclusion

  • Access: Jan Dhan accounts, Aadhaar and mobile (JAM) and UPI bring the excluded into the formal system at low cost.
  • Capital: household savings are mobilised for investment, and credit reaches MSMEs, women and farmers instead of moneylenders.
  • Public finance: direct benefit transfer cuts leakages, while micro-insurance and pensions cushion shocks so poor households can take productive risks.
  • Caveat: dormant accounts, thin small-borrower credit, the digital and literacy divide and weak grievance redress mean inclusion must be measured by usage, not accounts opened.

The market is a good engine but a poor steering wheel; a capable State and wide, well-used financial access are what make India's growth inclusive.

What are the major challenges of Public Distribution System (PDS) in India ? How can it be made effective and transparent ?

Approach · directive: “what / how”

What it asks · List the main problems of the PDS (targeting, leakage, storage, quality, governance) and give reforms that make it effective and transparent.

The question has 2 parts — answer each

  1. What: the major challenges of the Public Distribution System — targeting, leakage, supply chain, governance
  2. How: specific measures that make the PDS effective and transparent

Open with · Under the National Food Security Act, 2013 the PDS can reach three-quarters of rural and half of urban residents, yet leakages and exclusion errors dilute its impact.

Cover

  • Targeting: inclusion and exclusion errors, ghost or duplicate ration cards and diversion of grain to the open market.
  • Supply chain: storage and transport losses, poor-quality grain, procurement concentrated in a few States and low viability of fair price shops.
  • Governance: corruption and short-weighing at shops, weak grievance redress and low awareness of entitlements.
  • Reform through technology: end-to-end computerisation, Aadhaar-seeded cards, ePoS devices, GPS tracking of grain trucks, SMS alerts and online allocation portals.
  • Portability: One Nation One Ration Card, complete in all 36 States/UTs when Assam joined in June 2022, lets migrants draw rations anywhere.
  • Transparency: social audits and vigilance committees, public display of stocks and entitlements, helplines and NFSA grievance officers and State Food Commissions.
  • Structural reform: direct benefit transfer pilots, more millets and pulses, fair price shops as multi-service centres and modern FCI storage.

Close with · A dependable PDS needs clean beneficiary lists, technology-based tracking and citizen oversight, protecting food security at lower leakage and fiscal cost.

Model answer · 213 words (UPSC limit 150) · Minimalist IAS

Under the National Food Security Act, 2013 the PDS can reach three-quarters of rural and half of urban residents, which makes its leakages and exclusion errors a national concern.

Major challenges

  • Targeting: inclusion and exclusion errors, ghost and duplicate ration cards, and stale lists that leave out migrants and the newly poor.
  • Leakage: diversion of grain to the open market, short-weighing and corruption at fair price shops.
  • Supply chain: storage and transport losses, poor-quality grain, procurement concentrated in a few States and unviable shop margins.
  • Governance: weak grievance redress and low awareness of entitlements, while a cereal-heavy basket does little for nutrition.

Making it effective and transparent

  • Technology: end-to-end computerisation, Aadhaar-seeded cards, ePoS devices at shops, GPS tracking of grain trucks, SMS alerts and online allocation portals.
  • Portability: One Nation One Ration Card, complete across all 36 States/UTs when Assam joined in June 2022, lets migrants draw rations anywhere.
  • Accountability: social audits, vigilance committees, public display of stocks and entitlements, helplines, and the NFSA's grievance officers and State Food Commissions.
  • Structure: direct benefit transfer where markets work, millets and pulses in the basket, fair price shops as multi-service centres and modern FCI storage.

Clean beneficiary lists, tracked grain and citizen oversight together can deliver food security at lower leakage and lower fiscal cost.

Food processing links the farm to the fork and is the most direct route to value addition in agriculture: its gross value added rose to Rs 2.37 lakh crore in 2020-21, and it provides 12.2% of employment in registered manufacturing.

Scope

  • Levels: primary processing (cleaning, grading, milling), secondary (dairy products, canning, bakery, beverages) and tertiary (ready-to-eat, packaged and fortified foods).
  • Segments and linkages: dairy, fruits and vegetables, grains, meat, poultry and fisheries, with backward links to farms and forward links to packaging, logistics, cold chains and retail.
  • Market: a large farm base, rising incomes, urbanisation, changing diets and e-commerce widen demand at home, with room for exports; 100% FDI is allowed under the automatic route.

Significance

  • Farmers: lower post-harvest losses, steadier prices and remunerative markets through value addition and contract farming.
  • Jobs: labour-intensive and located near farms, suited to MSMEs, women and rural non-farm employment.
  • Nutrition and safety: fortification, longer shelf life and packaged food under FSSAI standards.
  • Trade: export earnings and import substitution in processed foods.
  • Constraints: weak cold chains, fragmented supply and low processing levels; PM Kisan SAMPADA, PMFME, the PLI scheme and mega food parks address them.

Stronger cold chains, farm-processor linkages and clear quality norms can turn farm surpluses into higher incomes, jobs and exports.

The increase in life expectancy in the country has led to newer health challenges in the community. What are those challenges and what steps need to be taken to meet them ?

Approach · directive: “what / what steps”

What it asks · Identify the health problems that come with longer lives (chronic disease, dementia, disability, mental health, costs) and the steps the State and society must take.

The question has 2 parts — answer each

  1. What: the newer health challenges that follow rising life expectancy — disease, disability, mental and social, system gaps
  2. What steps: specific measures to meet these challenges

Open with · Longer life is a success, but the added years bring more chronic illness, dependency and care needs unless health systems adapt.

Cover

  • Ageing: the share of people aged 60 and above rose to 10.1% in 2021 and is projected at 13.1% by 2031 (MoSPI, Elderly in India 2021).
  • Disease burden: rising non-communicable diseases such as diabetes, hypertension, heart disease and cancers, plus dementia, arthritis, vision and hearing loss and multiple illnesses together.
  • Mind and society: depression, loneliness, neglect and abuse of the elderly, and thinning of joint-family support.
  • System gaps: few geriatric specialists and services, high out-of-pocket costs, medicine overuse, weak long-term and palliative care, and inadequate pensions.
  • Health steps: primary care and screening at Health and Wellness Centres, the National Programme for Health Care of the Elderly, geriatric wards and home-based care.
  • Financing steps: wider health insurance such as Ayushman Bharat PM-JAY, broader pensions and incentives for savings for elder care.
  • Social steps: lifestyle prevention and vaccination, community day-care, age-friendly public spaces and enforcement of the Maintenance and Welfare of Parents and Senior Citizens Act, 2007.

Model answer · 230 words (UPSC limit 150) · Minimalist IAS

Longer life is a public-health success, but it changes the disease profile: the share of people aged 60 and above reached 10.1% in 2021 and is projected at 13.1% by 2031, and the added years bring more chronic illness and care needs.

Newer health challenges

  • Chronic disease: diabetes, hypertension, heart disease and cancers, often several together, replace infections as the main burden.
  • Degenerative conditions: dementia, arthritis, vision and hearing loss, falls and disability that need long-term care rather than cure.
  • Mind and society: depression, loneliness, neglect and abuse as joint families thin; older women, who live longer, are more often widowed and dependent.
  • System gaps: few geriatric specialists, high out-of-pocket costs, medicine overuse, weak palliative care and thin pensions.

Steps needed

  • Primary care: screening for chronic disease at Health and Wellness Centres, expansion of the National Programme for Health Care of the Elderly, geriatric wards, and home-based and palliative care.
  • Financing: hospital cover under Ayushman Bharat PM-JAY, wider pensions and incentives to save for old-age care.
  • Prevention: healthy lifestyles, adult vaccination and early screening to compress the years spent in illness.
  • Social support: community day-care, age-friendly public spaces, trained caregivers and enforcement of the Maintenance and Welfare of Parents and Senior Citizens Act, 2007.

The aim is to add life to years and not only years to life, through prevention, affordable elder care and communities that keep the old included.

Each year a large amount of plant material, cellulose, is deposited on the surface of Planet Earth. What are the natural processes this cellulose undergoes before yielding carbon dioxide, water and other end products ?

Approach · directive: “what”

What it asks · Trace how plant cellulose breaks down in nature (fragmentation, microbial enzymes, aerobic and anaerobic decay, humus formation) to give carbon dioxide, water and other products.

The question has 2 parts — answer each

  1. What: the natural processes that break cellulose down — fragmentation, microbial enzymatic hydrolysis and aerobic respiration — before it yields carbon dioxide and water
  2. What: the other pathways and end products — anaerobic decay, herbivore digestion, humus, fire and fossil carbon

Open with · Cellulose, the most abundant plant polymer, returns to the atmosphere through the carbon cycle, driven mostly by microbes.

Cover

  • Fragmentation: earthworms, termites and other detritivores shred litter, exposing more surface to microbes.
  • Enzymatic hydrolysis: fungi and bacteria secrete cellulase enzymes that split cellulose chains into cellobiose and then glucose.
  • Aerobic decomposition: microbes respire the glucose, releasing carbon dioxide, water and energy.
  • Anaerobic decay in waterlogged soils, paddy fields, wetlands and animal guts: fermentation and methanogenesis give organic acids, methane and carbon dioxide.
  • Herbivores: ruminants and termites depend on gut microbes to digest cellulose, returning carbon as carbon dioxide and methane.
  • Other end products: lignin-rich residues form humus, fire rapidly oxidises litter to carbon dioxide and water, and buried plant matter can turn into peat and coal over time.

Close with · These processes recycle carbon and nutrients and sustain soil fertility, though methane release links them to climate change.

Model answer · 222 words (UPSC limit 150) · Minimalist IAS

Cellulose, a long chain of glucose units and the most abundant plant polymer, returns to the atmosphere through the carbon cycle, and microbes do most of the work.

Breaking down the polymer

  • Fragmentation: earthworms, termites and other detritivores shred fallen leaves and wood; the smaller pieces expose far more surface to microbial attack.
  • Enzymatic hydrolysis: fungi and bacteria secrete cellulase enzymes that cut the cellulose chains into cellobiose and then into glucose.

From glucose to carbon dioxide and water

  • Aerobic respiration: in well-aerated soil and litter, microbes oxidise the glucose, releasing carbon dioxide, water and energy; this is the main route by which plant carbon returns to the air.

Other pathways and end products

  • Anaerobic decay: in waterlogged soils, wetlands, paddy fields and animal guts, fermentation and methanogenesis yield organic acids, methane and carbon dioxide.
  • Herbivores: ruminants and termites cannot digest cellulose themselves; gut microbes ferment it and the carbon leaves as carbon dioxide and methane.
  • Humus: lignin-rich residues resist decay and form dark humus that holds water and nutrients in the soil.
  • Fire and burial: fire oxidises litter rapidly to carbon dioxide and water, while plant matter buried away from oxygen can become peat and, over geological time, coal.

These processes close the carbon cycle and sustain soil fertility, though the methane released in wet conditions ties decomposition to climate change.

Discuss in detail the photochemical smog emphasizing its formation, effects and mitigation. Explain the 1999 Gothenburg Protocol.

Approach · directive: “discuss / explain”

What it asks · Explain how photochemical smog forms, what harm it causes and how to curb it, and state what the 1999 Gothenburg Protocol requires.

The question has 2 parts — answer each

  1. Discuss photochemical smog in detail: its formation, its effects and its mitigation
  2. Explain the 1999 Gothenburg Protocol: what it is and what it requires

Open with · Photochemical smog is a brown haze of ground-level ozone and other oxidants formed when sunlight acts on vehicle and industrial emissions.

Cover

  • Formation: nitrogen oxides and volatile organic compounds react in strong sunlight to make ozone, peroxyacetyl nitrate (PAN) and aldehydes; stagnant air and temperature inversion trap the haze.
  • Health effects: eye irritation, cough, asthma and lung damage, worst for children and the elderly.
  • Other effects: damage to crops and forests, cracked rubber and faded materials, poor visibility, and ozone adds to warming as a greenhouse gas.
  • Mitigation: cleaner fuels and tighter vehicle norms, catalytic converters, public transport and electric vehicles, controls on solvents and petrol vapour, and smog alerts.
  • Gothenburg Protocol, 1999: a UNECE protocol under the Convention on Long-range Transboundary Air Pollution that sets national emission ceilings for sulphur dioxide, nitrogen oxides, VOCs and ammonia to cut acidification, eutrophication and ground-level ozone.
  • It was the first multi-pollutant, multi-effect protocol; the amended version, in force since 2019, adds 2020 targets and fine particles (PM2.5).

Model answer · 223 words (UPSC limit 150) · Minimalist IAS

Photochemical smog is the brown haze of ground-level ozone and other oxidants that forms when strong sunlight acts on vehicle and industrial exhaust.

Formation

  • Precursors: nitrogen oxides and volatile organic compounds (VOCs) from vehicle exhaust, refineries, solvents and petrol vapour.
  • Reaction: in strong sunlight they react to form ozone, peroxyacetyl nitrate (PAN) and aldehydes; stagnant air and temperature inversion trap the haze over the city.

Effects

  • Health: eye irritation, cough, asthma and lung damage, worst for children and the elderly.
  • Environment and economy: damaged crops and forests, cracked rubber and faded materials, poor visibility, and ozone adds to warming as a greenhouse gas.

Mitigation

  • Cut precursors: cleaner fuels and tighter vehicle norms, catalytic converters, controls on industrial solvents and petrol vapour recovery.
  • Shift mobility: public transport and electric vehicles, with smog alerts to curb traffic on bad days.

Gothenburg Protocol, 1999

  • Adopted under the UNECE Convention on Long-range Transboundary Air Pollution, it sets national emission ceilings for sulphur dioxide, nitrogen oxides, VOCs and ammonia to cut acidification, eutrophication and ground-level ozone together.
  • It was the first multi-pollutant, multi-effect protocol; the amended version, in force since 2019, adds 2020 targets and fine particles (PM2.5).

Smog is made in the air from precursors, so coordinated control of nitrogen oxides and VOCs through clean transport and industry norms, the logic of Gothenburg, is the surest cure.

Explain the mechanism and occurrence of cloudburst in the context of the Indian subcontinent. Discuss two recent examples.

Approach · directive: “explain / discuss”

What it asks · Explain how cloudbursts occur (moist air, orographic lifting, convection), where in the subcontinent they occur, and give two recent examples with impacts.

The question has 3 parts — answer each

  1. Explain the mechanism of a cloudburst
  2. Explain its occurrence in the Indian subcontinent: where and when
  3. Discuss two recent examples and their impact

Open with · A cloudburst is a sudden, very intense and localised downpour, usually taken as more than 10 cm of rain in an hour over a small area of about 20 to 30 sq km.

Cover

  • Mechanism: warm, moist monsoon air is forced up steep slopes (orographic lift) and cools; towering cumulonimbus clouds form, with strong updrafts holding large water droplets aloft.
  • When the updraft weakens, or clouds are trapped in narrow valleys, the water falls all at once; interaction with westerly disturbances can intensify it.
  • Occurrence: mostly in the monsoon, in the Himalayan belt (Uttarakhand, Himachal Pradesh, Jammu and Kashmir, Ladakh) and at times the Western Ghats, on mid-elevation slopes.
  • Effects: flash floods, landslides and debris flows that damage roads, bridges and homes, worsened by deforestation, road-cutting and unplanned construction on fragile slopes.
  • Examples: the Amarnath cave area, Jammu and Kashmir, in July 2022, which swept away camps of pilgrims; and Kishtwar, Jammu and Kashmir, in July 2021, which caused deaths and destroyed houses.
  • Response: exact forecasting is not yet possible, so dense Doppler radar and automatic weather stations, nowcasting, hazard zoning, early warning and regulated construction are needed.

Close with · Cloudbursts cannot be prevented; resilience lies in better nowcasting, disciplined land use in the hills and community preparedness.

Model answer · 229 words (UPSC limit 150) · Minimalist IAS

A cloudburst is a sudden, very intense and localised downpour, taken by IMD as more than 10 cm of rain in an hour over roughly 20 to 30 sq km.

Mechanism

  • Warm, moist monsoon air is forced up steep slopes (orographic lift) and cools, building towering cumulonimbus clouds whose strong updrafts hold large water droplets aloft.
  • When the updraft weakens, or clouds are hemmed in by narrow valleys, the stored water falls all at once; interaction with a western disturbance can intensify the event.

Occurrence

  • Mostly during the monsoon on mid-elevation slopes of the Himalayan belt (Uttarakhand, Himachal Pradesh, Jammu and Kashmir, Ladakh) and at times in the Western Ghats.
  • Damage is magnified by deforestation, road-cutting and unplanned construction on fragile slopes and riverbeds, turning heavy rain into flash floods, landslides and debris flows.

Two recent examples

  • Amarnath, Jammu and Kashmir, 8 July 2022: a cloudburst near the holy cave sent flash floods through the pilgrims' camps, sweeping away tents and taking lives.
  • Kishtwar, Jammu and Kashmir, 28 July 2021: a cloudburst in a remote village caused deaths and destroyed houses.

Response

  • Exact forecasting is not yet possible, so dense Doppler radar and automatic weather stations, nowcasting, hazard zoning, early warning and regulated construction are the tools.

Cloudbursts cannot be prevented; resilience lies in better nowcasting, disciplined land use in the hills and communities that know when to move.

Discuss the types of organised crimes. Describe the linkages between terrorists and organised crime that exist at the national and transnational levels.

Approach · directive: “discuss / describe”

What it asks · List the main types of organised crime, then describe how terrorists link with crime groups within India and across borders.

The question has 3 parts — answer each

  1. Discuss the types of organised crime
  2. Describe the linkages between terrorists and organised crime at the national level
  3. Describe the linkages at the transnational level

Open with · Organised crime is a continuing criminal enterprise for profit, backed by violence and corruption; when it meets terrorism, each strengthens the other.

Cover

  • Types: drug and arms trafficking, human trafficking, extortion and protection rackets, smuggling of gold and wildlife, fake currency, illegal mining, cybercrime, contract killing and money laundering.

Model answer · 221 words (UPSC limit 150) · Minimalist IAS

Organised crime is a continuing criminal enterprise run for profit and sustained by violence and corruption; terrorism pursues political ends, but the two increasingly share money, routes and manpower.

Types of organised crime

  • Trafficking: drugs, arms, humans and wildlife, and smuggling of gold and other contraband.
  • Predatory: extortion and protection rackets, contract killing and illegal mining.
  • Financial and cyber: fake currency, hawala and money laundering, and cybercrime.

National linkages

  • Funding: extortion and levies on contractors and traders finance insurgent and extremist groups.
  • Logistics: narcotics and arms smuggling in Punjab and Jammu and Kashmir, fake currency and hawala channels that move terror money, and local gangs that supply shelter, weapons and couriers.
  • Nexus: the Vohra Committee (1993) pointed to ties among crime syndicates, politicians and officials that shelter both crime and terror.

Transnational linkages

  • Narco-terror: drug routes from the Golden Crescent and Golden Triangle finance terror groups and carry arms and explosives across borders.
  • Syndicates: crime networks with terror links, as in the 1993 Mumbai blasts, where a smuggling network landed the explosives.
  • Enablers: porous borders, the dark web and cryptocurrency, hawala and shell companies, corrupt enforcement and safe havens abroad.

Cutting the money, the arms routes and the protection networks, through NIA and UAPA, financial intelligence (FIU-IND, FATF standards) and cooperation under UN conventions, is central to breaking the crime-terror nexus.

What are the maritime security challenges in India ? Discuss the organisational, technical and procedural initiatives taken to improve the maritime security.

Approach · directive: “what / discuss”

What it asks · Set out India's maritime security challenges and discuss the organisational, technical and procedural steps taken to improve coastal and maritime security.

The question has 4 parts — answer each

  1. What: the maritime security challenges India faces
  2. Discuss the organisational initiatives taken to improve maritime security
  3. Discuss the technical initiatives
  4. Discuss the procedural initiatives

Open with · With a long coastline, island territories and busy sea lanes, India faces threats from the sea that range from terrorism to piracy and illegal fishing.

Cover

  • Challenges: sea-borne terrorism as in 26/11, piracy, smuggling of arms, drugs and people, illegal fishing and migration, maritime boundary disputes and a growing extra-regional naval presence.
  • Other risks: vulnerable ports and offshore assets, cyber attacks on port systems, oil spills and marine disasters.
  • Organisational: the Navy leads overall maritime security, the Coast Guard the coastal waters and Marine Police the shallows, coordinated by the National Committee for Strengthening Maritime and Coastal Security and joint operations centres.
  • Technical: coastal radar chain, AIS transponders and vessel tracking, the National Command Control Communication and Intelligence network, and the Information Fusion Centre for the Indian Ocean Region.
  • Procedural: registration and identity cards for fishermen and boats, coastal exercises such as Sea Vigil and Sagar Kavach, ISPS Code port security, and information-sharing protocols among agencies.

With a long coastline, island territories and busy sea lanes, India faces threats from the sea that range from terrorism to piracy and illegal fishing; the 26/11 attack exposed how thin coastal security was.

Maritime security challenges

  • Threats: sea-borne terrorism as on 26/11, piracy, smuggling of arms, drugs and people, and illegal fishing and migration.
  • Strategic: maritime boundary disputes and a growing extra-regional naval presence in the Indian Ocean.
  • Vulnerabilities: ports and offshore assets, cyber attacks on port systems, oil spills and marine disasters.

Organisational initiatives

  • A three-tier structure: the Navy leads overall maritime security, the Coast Guard covers coastal waters and Marine Police the shallows, coordinated by the National Committee for Strengthening Maritime and Coastal Security and joint operations centres.

Technical initiatives

  • A coastal radar chain, AIS transponders and vessel tracking, the National Command Control Communication and Intelligence network, and the Information Fusion Centre for the Indian Ocean Region.

Procedural initiatives

  • Identity cards for fishermen and registration of boats, coastal security exercises such as Sea Vigil and Sagar Kavach, ISPS Code security at ports and information-sharing protocols among agencies.
  • Regional: the SAGAR vision, joint patrols and anti-piracy cooperation with Indian Ocean partners.

Gaps remain in manpower, coordination among many agencies and asset maintenance; seamless intelligence sharing, well-equipped State marine police and fishing communities as the eyes of the coast are the weakest links to fix.

“Economic growth in the recent past has been led by increase in labour productivity.” Explain this statement. Suggest the growth pattern that will lead to creation of more jobs without compromising labour productivity.

Approach · directive: “explain / suggest”

What it asks · Explain how recent growth came from higher output per worker (capital deepening, technology, services) and not from more jobs, and suggest a growth pattern that adds jobs without lowering productivity.

The question has 2 parts — answer each

  1. Explain the statement: how recent growth has come from rising labour productivity rather than from more jobs
  2. Suggest a growth pattern that creates more jobs without compromising labour productivity

Open with · When output rises faster than employment, growth is productivity-led: good for incomes, weak for jobs.

Cover

  • Meaning: rising output per worker through mechanisation, automation, IT and capital-intensive industry lets GDP grow with slow job growth, so the employment elasticity of growth stays low.
  • Drivers: movement of workers out of agriculture, growth of high-productivity services and finance, formal-sector capital deepening and technology adoption.
  • Result: low-employment growth, a large low-productivity informal sector and disguised unemployment on farms.
  • Manufacturing for jobs: promote labour-intensive, export-oriented sectors such as textiles, apparel, leather, footwear, toys and food processing, with incentives linked to jobs and productivity.
  • MSMEs and services: raise MSME productivity through credit, technology and formalisation, and grow tourism, construction, healthcare, care services and digital services.
  • Enablers: skills and apprenticeships, infrastructure and logistics, simpler labour compliance with social security, more women in the workforce and rural non-farm jobs.

Close with · The aim is productive jobs: pair technology and skills with labour-intensive sectors so that productivity and employment rise together.

Model answer · 256 words (UPSC limit 250) · Minimalist IAS

Growth is productivity-led when output rises faster than employment; India's recent growth has raised output per worker far more than the number of workers, which is good for incomes but weak for jobs.

Explaining the statement

  • Meaning: labour productivity is output per worker; when GDP grows mainly because each worker produces more, the employment elasticity of growth stays low and jobs lag behind output.
  • Drivers: mechanisation, automation and IT in the formal sector, capital deepening in manufacturing, and rapid growth of high-productivity services such as finance and software.
  • Structural shift: workers leaving low-productivity agriculture raise average productivity even when few new formal jobs are created.
  • Result: low-employment growth, a large low-productivity informal sector and disguised unemployment on farms, so productivity gains stay concentrated in a small formal segment.

A growth pattern for jobs and productivity

  • Labour-intensive manufacturing: textiles, apparel, leather, footwear, toys and food processing, with incentives linked to jobs created and productivity, not to capital alone.
  • MSMEs: credit, technology, cluster infrastructure and formalisation to raise productivity where most workers actually are.
  • Services with mass jobs: tourism, construction, healthcare, care services and digital services that absorb workers at rising skill levels.
  • Skills: apprenticeships and industry-linked training so that workers move into higher-productivity work rather than being displaced by it.
  • Enablers: infrastructure and logistics, simpler labour compliance with social security, more women in the workforce and rural non-farm jobs.

The aim is productive jobs: pair technology and skills with labour-intensive sectors so that productivity and employment rise together rather than one at the expense of the other.

Do you think India will meet 50 percent of its energy needs from renewable energy by 2030 ? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective ? Explain.

Approach · directive: “do you think / justify / explain”

What it asks · Judge whether India can reach 50% of its energy from renewables by 2030, separating power capacity from total energy, and explain how shifting subsidies from fossil fuels to renewables helps.

The question has 2 parts — answer each

  1. Do you think India will meet 50% of its energy needs from renewables by 2030: take a position and justify it, separating installed power capacity from total energy
  2. Explain how shifting subsidies from fossil fuels to renewables helps achieve the objective

Open with · India's updated NDC (2022) commits to about 50% of installed electric power capacity from non-fossil sources by 2030, which is not the same as 50% of all energy used.

Cover

  • Capacity is within reach: rapid solar and wind additions, large auctions, falling tariffs and the 500 GW non-fossil capacity ambition make the power-capacity goal achievable; by 30 June 2025 non-fossil sources already made up about 50 per cent of installed capacity (242.78 GW of 484.82 GW), five years early.
  • Total energy is harder: transport, industry and cooking still run on oil, coal and gas, so renewables' share of all energy will stay far smaller than their share of installed capacity.
  • Constraints: intermittency and lack of storage, transmission and grid integration, land, weak DISCOM finances, import dependence for solar modules and coal's role in baseload.
  • Subsidy shift as a price signal: cutting fossil subsidies and backing renewables, storage and green hydrogen narrows the cost gap and steers investment.
  • Fiscal and equity gains: it frees funds for clean energy and social spending, lowers the import bill and emissions; the poor need targeted transfers and coal-region workers a just transition.
  • Way forward: storage and grid upgrades, domestic manufacturing, rooftop and decentralised solar, energy efficiency, electrified transport and carbon pricing.

Close with · India has already met the power-capacity target (mid-2025), but 50% of total energy needs by 2030 is a stretch, so storage, grids and smart subsidy reform matter most.

Question: UPSC's CS (Main) 2022, GS Paper III — paper ↗. Approach: Minimalist IAS, checked 30 Sept 2026 (how we verify) — UPSC publishes no model answers. ·

Model answer · 299 words (UPSC limit 250) · Minimalist IAS

India's updated NDC (2022) commits to about 50% of installed electric power capacity from non-fossil sources by 2030; that is a power-capacity target, not 50% of all energy consumed, and the answer differs for the two.

Position: capacity yes, total energy no

  • Capacity is within reach: rapid solar and wind additions, large auctions, falling tariffs and the 500 GW non-fossil ambition make the power-capacity goal achievable (since then, by 30 June 2025 non-fossil sources already made up about 50% of installed capacity, 242.78 GW of 484.82 GW, five years early).
  • Total energy is harder: transport, industry and cooking still run on oil, coal and gas, so renewables' share of all energy used will stay far below their share of installed capacity, and capacity overstates generation because solar and wind run for fewer hours than coal plants.
  • Constraints: intermittency and lack of storage, transmission and grid integration, land, weak DISCOM finances, import dependence for solar modules and coal's role in baseload supply.

How the subsidy shift helps

  • Price signal: cutting fossil subsidies raises the relative price of coal, oil and gas, while support for renewables, storage and green hydrogen narrows the cost gap and steers private investment.
  • Fiscal space: money freed from fossil subsidies can fund grid upgrades, storage and rooftop solar for households and small firms.
  • External and environmental gains: a lower import bill and lower emissions.
  • Equity conditions: the poor need targeted transfers and coal-region workers a just transition, or reform will stall politically.

Way forward

  • Storage and grid upgrades, domestic manufacturing, rooftop and decentralised solar, energy efficiency, electrified transport and carbon pricing.

India has met the power-capacity milestone ahead of time, but half of all energy needs from renewables by 2030 remains a stretch; storage, grids and well-designed subsidy reform will decide how far the gap closes.

What are the main bottlenecks in upstream and downstream process of marketing of agricultural products in India ?

Approach · directive: “what”

What it asks · Identify the obstacles before produce reaches the market (upstream: farm level, aggregation, mandis) and after (downstream: storage, transport, processing, retail).

The question has 2 parts — answer each

  1. What: the main bottlenecks in the upstream process — at the farm, in aggregation and in the mandi
  2. What: the main bottlenecks in the downstream process — storage, transport, processing and retail

Open with · Farmers receive only a modest share of the consumer's rupee because of weak links at every stage between farm and market.

Cover

  • Upstream: small, scattered holdings, lack of grading, standards and aggregation, limited credit, inputs and price information, and distress sales after harvest.
  • Mandi system: few regulated markets, APMC monopoly, dominance of commission agents, market fees, cartelisation and delayed payments.
  • Downstream: many intermediaries, heavy post-harvest losses, poor rural roads and cold chains, inadequate warehouses and low processing.
  • Regulation: stock limits and export curbs under the Essential Commodities Act and trade policy swings discourage private storage and investment and add price volatility.
  • Institutional gaps: thin reach of e-NAM, weak farmer producer organisations, limited warehouse-receipt finance and few safeguards in contract farming.
  • Remedies: aggregation through FPOs, APMC reform on the lines of the 2017 model law, e-NAM and direct marketing, the Agri Infrastructure Fund for storage and cold chains, and stable trade policy.

Close with · Better aggregation, storage and market access under predictable rules would shrink the farm-to-fork gap and raise farmers' share.

Model answer · 248 words (UPSC limit 250) · Minimalist IAS

Farmers get a modest share of the consumer's rupee because the chain from farm to market is weak at every link, both before produce reaches the mandi (upstream) and after it leaves (downstream).

Upstream bottlenecks

  • Fragmented supply: small, scattered holdings produce small lots with no grading, standards or aggregation, leaving farmers with little bargaining power.
  • Information and credit: limited price information, credit and inputs push farmers into distress sales soon after harvest, when prices are lowest.
  • Mandi system: too few regulated markets, APMC monopoly, dominance of commission agents, high market fees, cartelisation among traders and delayed payments.
  • Regulation: stock limits and export curbs under the Essential Commodities Act and sudden trade-policy swings discourage private investment and add to price volatility.

Downstream bottlenecks

  • Intermediaries: many layers between mandi and consumer, each adding margin without adding value.
  • Losses: poor rural roads, inadequate warehouses and thin cold chains cause heavy post-harvest losses, especially in fruits, vegetables and milk.
  • Processing and retail: low processing levels and weak links between farmers, processors and organised retail keep value addition low.
  • Institutions: thin reach of e-NAM, weak farmer producer organisations, limited warehouse-receipt finance and few safeguards in contract farming.

Way forward

  • Aggregation through FPOs, APMC reform on the lines of the 2017 model law, e-NAM and direct marketing, the Agriculture Infrastructure Fund for storage and cold chains, and a stable trade policy.

Better aggregation, storage and market access under predictable rules would shrink the farm-to-fork gap and raise the farmer's share of the final price.

What is Integrated Farming System ? How is it helpful to small and marginal farmers in India ?

Approach · directive: “what / how”

What it asks · Define the Integrated Farming System and show how it benefits small and marginal farmers.

The question has 2 parts — answer each

  1. What is Integrated Farming System: define it and explain how it works
  2. How it helps small and marginal farmers in India

Open with · Integrated Farming System (IFS) combines crops with livestock, fish, poultry, bees, trees and biogas on one farm so that the waste of one enterprise feeds another.

Cover

  • Concept: a whole-farm, resource-recycling approach in which crop residue becomes fodder, dung becomes manure and biogas and pond water irrigates crops.
  • Income and risk: several enterprises give earnings through the year; if a crop fails, milk, eggs, fish or vegetables cushion the loss.
  • Cost and resources: recycling cuts spending on fertiliser, feed and energy, and raises the productivity of land, water and labour on small plots.
  • Employment and nutrition: work is spread across the year and uses family labour, including women, and improves food and nutrition security.
  • Sustainability: better soil health, less chemical use and greater climate resilience; agroforestry and water harvesting can be added.
  • Constraints and support: start-up capital, skills and market links limit adoption; Krishi Vigyan Kendras, ICAR farming-system models, FPOs, livestock and fisheries schemes and MGNREGA convergence help.

Close with · For small farms, integration is a practical route to stable income, lower risk and sustainable farming.

Model answer · 252 words (UPSC limit 250) · Minimalist IAS

Integrated Farming System (IFS) combines crops with livestock, fish, poultry, bees, trees and biogas on a single farm, so that the waste or by-product of one enterprise becomes the input of another.

What IFS is

  • A whole-farm, resource-recycling approach: crop residue becomes fodder, dung becomes manure and biogas, and pond water irrigates crops.
  • It is planned around the farm's land, water, labour and market, so the mix of enterprises differs by region and farm size, and ICAR has developed location-specific farming-system models.

How it helps small and marginal farmers

  • Income through the year: milk, eggs, fish, honey and vegetables bring regular cash between crop harvests.
  • Lower risk: if a crop fails, the other enterprises cushion the loss.
  • Lower costs: recycling cuts spending on fertiliser, feed and energy, so net income on a small plot rises.
  • Higher resource productivity: more output per unit of land, water and labour, which matters most where holdings are tiny.
  • Employment and nutrition: work is spread across the year and uses family labour, including women, and the diverse produce improves household nutrition.
  • Sustainability: better soil health, less chemical use and greater climate resilience; agroforestry and water harvesting can be added.

Constraints and support

  • Start-up capital, skills and market links limit adoption; Krishi Vigyan Kendras, ICAR farming-system models, FPOs, livestock and fisheries schemes and convergence with MGNREGA for farm ponds and cattle sheds help.

For small farms, integration is a practical route to stable income, lower risk and sustainable farming, and it deserves the first claim on extension effort.

Launched on 25 December 2021, the James Webb Space Telescope (JWST), led by NASA with the European and Canadian space agencies, is the most powerful space observatory built so far, designed to see the universe in infrared.

Unique features

  • Mirror: a 6.5-metre segmented, gold-coated primary mirror of 18 hexagonal pieces, far larger than Hubble's 2.4 m, gathers much more light.
  • Infrared vision: it observes mainly near- and mid-infrared light, so it sees through dust and detects very distant, red-shifted early galaxies invisible to Hubble, which works mostly in optical and ultraviolet light.
  • Cold operation: a five-layer sunshield keeps the instruments very cold so their own heat does not swamp faint infrared signals.
  • Location: it orbits the Sun-Earth L2 point about 1.5 million km away, where cold, stable conditions allow uninterrupted observation, unlike Hubble in low Earth orbit.

Key goals

  • See the first stars and galaxies that formed after the Big Bang.
  • Study how galaxies, stars and planetary systems form and evolve.
  • Analyse exoplanet atmospheres for water and other signs of habitability.

Potential benefits

  • Knowledge: a deeper understanding of cosmic origins and of whether life exists elsewhere.
  • Technology: spin-offs in infrared detectors, precision optics and lightweight materials.
  • Cooperation and inspiration: an international scientific partnership and a spur to science education.
  • Caveat: it cannot be serviced like Hubble, and it came at high cost after long delays.

JWST extends humanity's view to the edge of the observable universe and, through its technology and inspiration, benefits science on Earth too.

What is the basic principle behind vaccine development ? How do vaccines work ? What approaches were adopted by the Indian vaccine manufacturers to produce COVID-19 vaccines ?

Approach · directive: “what / how”

What it asks · State the immunological principle behind vaccines, explain how they trigger protection, and outline the platforms Indian manufacturers used for COVID-19 vaccines.

The question has 3 parts — answer each

  1. What is the basic principle behind vaccine development
  2. How do vaccines work
  3. What approaches Indian manufacturers adopted to produce COVID-19 vaccines

Open with · A vaccine trains the immune system to recognise a pathogen without causing the disease, so the body responds faster and harder on real exposure.

Cover

  • Principle: exposure to a harmless form or part of a pathogen (the antigen) prompts adaptive immunity and leaves memory cells; widespread immunity also gives herd protection.
  • How they work: antigen-presenting cells alert helper T cells; B cells make antibodies and killer T cells destroy infected cells; memory cells persist, and boosters and adjuvants strengthen the response.
  • Platforms in general: live attenuated, inactivated, subunit or protein, toxoid, viral vector, and DNA and mRNA vaccines.
  • Covaxin (Bharat Biotech with ICMR and NIV Pune) is an indigenous inactivated whole-virion vaccine.
  • Covishield (Serum Institute of India) is the Oxford-AstraZeneca viral-vector vaccine, using a chimpanzee adenovirus, made under licence.
  • Others: ZyCoV-D (Zydus) is a DNA plasmid vaccine, Corbevax (Biological E) a recombinant protein-subunit vaccine, Sputnik V an adenovirus-vector vaccine produced by Indian partners, followed by mRNA and nasal candidates.

A vaccine trains the immune system to recognise a pathogen without causing the disease, so that on real exposure the body responds faster and harder.

Basic principle

  • Exposure to a harmless form or part of a pathogen (the antigen) prompts adaptive immunity and leaves behind memory cells, so the body mounts a rapid secondary response on infection.
  • Population effect: when enough people are immune, transmission falls and even the unvaccinated gain herd protection.

How vaccines work

  • Antigen-presenting cells process the antigen and alert helper T cells.
  • B cells make antibodies that neutralise the pathogen, while killer T cells destroy infected cells.
  • Memory B and T cells persist for years; adjuvants strengthen the response and boosters renew waning immunity.
  • Platforms: live attenuated, inactivated, subunit or protein, toxoid, viral vector, DNA and mRNA vaccines differ in how they present the antigen.

Indian approaches to COVID-19 vaccines

  • Inactivated whole virion: Covaxin, developed indigenously by Bharat Biotech with ICMR and NIV Pune.
  • Viral vector: Covishield, the Oxford-AstraZeneca chimpanzee-adenovirus vaccine, made under licence by the Serum Institute of India; Sputnik V, an adenovirus-vector vaccine, produced by Indian partners.
  • DNA plasmid: ZyCoV-D (Zydus), a plasmid DNA vaccine.
  • Protein subunit: Corbevax (Biological E), a recombinant protein-subunit vaccine.
  • Later: mRNA and intranasal candidates followed, widening the toolkit.

A mix of indigenous and licensed platforms gave India scale and choice during the pandemic and left it with stronger vaccine-making capacity for the future.

  3. Explain the control measures to bring down greenhouse gases, in the light of the Kyoto Protocol, 1997

Open with · Global warming is the rise in average surface temperature caused mainly by greenhouse gases from human activity since the Industrial Revolution.

Cover

  • Causes: burning fossil fuels, deforestation, agriculture and industry raise carbon dioxide, methane, nitrous oxide and fluorinated gases.
  • Effects on climate: higher temperatures, melting glaciers and rising seas, more intense heat waves, cyclones, floods and droughts, shifting monsoons and ocean acidification.
  • Kyoto Protocol basics: adopted in 1997 under the UNFCCC and in force from 2005, it set legally binding limits on industrialised (Annex I) countries, an average of 5% below 1990 levels over 2008-2012.
  • Principle and tools: common but differentiated responsibilities, with flexible mechanisms, namely emissions trading, Joint Implementation and the Clean Development Mechanism, from which India gained.
  • Second period: the Doha Amendment (2012) set a further commitment for 2013-2020 with fewer participants.
  • Assessment: the United States never ratified, Canada withdrew and large developing emitters had no binding limits, which led to the Paris Agreement's nationally determined contributions (2015).

Model answer · 264 words (UPSC limit 250) · Minimalist IAS

Global warming is the rise in the Earth's average surface temperature, caused mainly by greenhouse gases that human activity has added since the Industrial Revolution.

Global warming and its causes

  • Greenhouse effect: carbon dioxide, methane, nitrous oxide and fluorinated gases trap outgoing heat; more of them means a warmer surface.
  • Sources: burning fossil fuels for power, transport and industry, deforestation, agriculture and livestock, and industrial processes.

Effects on the global climate

  • Heat: higher average temperatures and more intense and frequent heat waves.
  • Water: melting glaciers and ice sheets, rising seas and more intense cyclones, floods and droughts.
  • Systems: shifting monsoon patterns, ocean warming and acidification, and stress on ecosystems, food and water supplies.

Control measures and the Kyoto Protocol

  • Kyoto basics: adopted in 1997 under the UNFCCC and in force from 2005, it set legally binding targets for industrialised (Annex I) countries, an average cut of 5% below 1990 levels over 2008-2012.
  • Principle: common but differentiated responsibilities, so developing countries, including India, had no binding limits.
  • Flexible mechanisms: emissions trading, Joint Implementation and the Clean Development Mechanism, through which Indian projects earned carbon credits.
  • Second period: the Doha Amendment (2012) set a further commitment for 2013-2020 with fewer participants.
  • Limits: the United States never ratified, Canada withdrew and large developing emitters had no binding limits, which led to the Paris Agreement's nationally determined contributions (2015).
  • Measures beyond Kyoto: renewables and energy efficiency, protecting forests and other sinks, methane control, carbon pricing and carbon capture.

Kyoto pioneered binding targets and carbon markets; the task now is universal, stronger and verifiable action under the Paris framework.

Explain the causes and effects of coastal erosion in India. What are the available coastal management techniques for combating the hazard ?

Approach · directive: “explain / what”

What it asks · Explain the natural and human causes of coastal erosion in India, its effects on people and ecosystems, and the hard, soft and policy tools available to manage it.

The question has 3 parts — answer each

  1. Explain the causes of coastal erosion in India, natural and human
  2. Explain its effects on people and ecosystems
  3. What coastal management techniques are available to combat it: hard, soft and policy tools

Open with · Coastal erosion is the loss of shoreline to waves, currents and storms; the National Centre for Coastal Research found that about a third of India's mainland coast (33.6% over 1990 to 2018) is eroding to varying degrees.

Cover

  • Natural causes: wave action, longshore currents, storms and cyclones, sea-level rise, tides and loss of sediment supply.
  • Human causes: dams and sand mining that cut river sediment, ports and harbours that block sand drift, seawalls that shift erosion elsewhere, destruction of mangroves and dunes, and coastal construction.
  • Effects on people: loss of land, homes and livelihoods, especially of fishing communities, saltwater intrusion, damage to roads, ports and tourism, and displacement.
  • Effects on ecology: loss of beaches, mangroves and wetlands, damaged turtle habitats and greater flood and storm-surge risk.
  • Hard techniques: seawalls, groynes, breakwaters, revetments and offshore reefs; effective locally but costly and may move erosion down the coast.
  • Soft and policy measures: beach nourishment, mangrove and dune restoration, shelterbelts, Coastal Regulation Zone rules, shoreline mapping, integrated coastal zone management and managed retreat.

Close with · Working with natural buffers, curbing sand mining and planning coastal settlements with shoreline data offer the most lasting protection.

Coastal erosion is the loss of shoreline to waves, currents and storms; the National Centre for Coastal Research found that about a third of India's mainland coast (33.6% over 1990 to 2018) is eroding to varying degrees.

Causes

  • Natural: wave action, longshore currents, storms and cyclones, tides, sea-level rise and loss of sediment supply.
  • Human: dams and river-sand mining that cut the sediment reaching the coast; ports, harbours and breakwaters that block the natural drift of sand; seawalls that shift erosion down-coast; destruction of mangroves and dunes; and construction on the shore itself.

Effects

  • People: loss of land, homes and livelihoods, especially of fishing communities; saltwater intrusion into wells and fields; damage to roads, ports and tourism; and displacement.
  • Ecology: loss of beaches, mangroves and wetlands, damaged turtle-nesting habitats and greater exposure to floods and storm surges.

Coastal management techniques

  • Hard engineering: seawalls, groynes, breakwaters, revetments and offshore reefs protect a stretch directly; they work locally but are costly, need maintenance and often shift erosion to the next stretch of coast.
  • Soft engineering: beach nourishment with dredged sand, restoration of mangroves and dunes, and coastal shelterbelts that absorb wave energy and rebuild themselves after storms.
  • Policy and planning: Coastal Regulation Zone rules, shoreline mapping and zoning, integrated coastal zone management, curbs on sand mining, and managed retreat where protection is not viable.

Working with natural buffers, curbing sand mining and planning settlements with shoreline data offer the most lasting protection.

What are the different elements of cyber security ? Keeping in view the challenges in cyber security, examine the extent to which India has successfully developed a comprehensive National Cyber Security Strategy.

Approach · directive: “what / examine the extent”

What it asks · List the elements of cyber security, then assess how far India has built a comprehensive national cyber security strategy in view of current challenges.

The question has 2 parts — answer each

  1. What: the different elements of cyber security
  2. Examine, keeping the challenges in view, the extent to which India has developed a comprehensive National Cyber Security Strategy: what exists, what is missing and a verdict

Open with · Cyber security protects networks, devices and data across government, business and citizens, and a national strategy ties the technical, legal and institutional pieces together.

Cover

  • Technical elements: network, application, endpoint and cloud security, identity and access control, data protection and encryption, incident response and recovery, and user awareness.
  • National elements: protection of critical information infrastructure, law and policy, institutions, a skilled workforce, research and international cooperation.
  • Challenges: state-linked and criminal attacks, ransomware and data breaches, dependence on foreign hardware and software, IoT and 5G expansion, skill shortages and under-reporting.
  • India's framework: IT Act, 2000 (amended 2008), CERT-In, NCIIPC for critical infrastructure, National Cyber Security Policy 2013, the Indian Cyber Crime Coordination Centre and the Defence Cyber Agency.
  • Gaps: the 2013 policy is dated and a full national strategy was still awaited at the time of the paper; agency roles overlap, and state capacity and private-sector obligations are limited.
  • Way forward: a published, funded strategy with clear roles, mandatory incident reporting, standards and audits, indigenous technology, skilling, public-private partnership and treaty cooperation.

Close with · India has built many of the pieces; what remains is a single, well-resourced strategy with clear accountability.

Add value (verified)

  • CERT-In directions of 28 April 2022 (under section 70B(6) of the IT Act, 2000): service providers, intermediaries, data centres, body corporates and government organisations must report cyber incidents to CERT-In within 6 hours of noticing them. Directions under sub-section (6) of section 70B of the Information Technology Act, 2000 — CERT-In, 28 April 2022 ↗“Any service provider, intermediary, data centre, body corporate and Government organisation shall mandatorily report cyber incidents as mentioned in Annexure I to CERT-In within 6 hours of noticing such incidents or being brought to notice about such incidents.”

Cyber security protects the networks, devices and data of government, business and citizens; a national strategy ties the technical, legal and institutional pieces into one plan with clear accountability.

Elements of cyber security

  • Technical: network, application, endpoint and cloud security; identity and access control; data protection and encryption; incident response and recovery.
  • Human: user awareness, a skilled workforce and a security culture in organisations.
  • National: protection of critical information infrastructure, law and policy, institutions, research and international cooperation.

Challenges

  • State-linked and criminal attacks, ransomware and data breaches, dependence on foreign hardware and software, the wider attack surface of IoT and 5G, skill shortages and under-reporting of incidents.

How far India has a comprehensive strategy

  • Building blocks exist: the IT Act, 2000 (amended 2008); CERT-In for incident response; NCIIPC for critical infrastructure; the National Cyber Security Policy 2013; the Indian Cyber Crime Coordination Centre; and the Defence Cyber Agency.
  • Recent tightening: CERT-In's directions of April 2022 require service providers, intermediaries, data centres, companies and government bodies to report cyber incidents within six hours.
  • Gaps: the 2013 policy is dated and a full national strategy was still awaited at the time of the paper; agency roles overlap; State police capacity is thin; private-sector obligations remain limited.
  • Verdict: India has assembled many of the pieces, but not yet a single, funded and comprehensive strategy that fixes accountability.

Way forward

  • A published, funded strategy with clear roles; mandatory incident reporting enforced through audits and standards; indigenous technology; skilling; public-private partnership; and treaty cooperation.

India has built most of the parts; a single, well-resourced strategy with clear accountability is what would make them a system.

Naxalism is a social, economic and developmental issue manifesting as a violent internal security threat. In this context, discuss the emerging issues and suggest a multilayered strategy to tackle the menace of Naxalism.

Approach · directive: “discuss / suggest”

What it asks · Discuss the new issues in tackling Left-wing extremism and propose a multilayered strategy across security, development, rights and outreach.

The question has 2 parts — answer each

  1. Discuss the emerging issues in tackling Naxalism, seen as a social, economic and developmental problem with a violent security face
  2. Suggest a multilayered strategy to tackle it: security, development, rights and governance, outreach

Open with · Naxalism thrives where poverty, land and forest grievances and weak governance meet, so the response must go beyond policing.

Cover

  • Root causes: tribal alienation, displacement for mines and dams, unimplemented forest and land rights, poor services and exploitation by contractors and officials.
  • Emerging issues: a shrinking but entrenched core in areas such as Dandakaranya and Jharkhand, use of IEDs and forest terrain, extortion funding, urban support networks and human-rights concerns in operations.
  • Security layer: intelligence-led operations with State and central forces working together, better-trained State police, fortified posts and the SAMADHAN principles, including actionable intelligence, technology and cutting access to finance.
  • Development layer: roads, mobile connectivity, schools, health and banking in affected districts, with the Aspirational Districts programme and central assistance for LWE areas.
  • Rights and governance layer: implement the Forest Rights Act and PESA, fair land acquisition and rehabilitation, accountable local administration and quick redress of tribal grievances.
  • Outreach layer: dialogue, surrender and rehabilitation policy, community policing and counter-narrative, and stopping the flow of funds and arms.

Close with · Sustained security pressure, visible development and rights delivery, and the trust of local communities together can end the movement's appeal.

Model answer · 247 words (UPSC limit 250) · Minimalist IAS

Naxalism thrives where poverty, land and forest grievances and weak governance meet; the violence is the symptom, so the response must go beyond policing.

Emerging issues

  • Root causes persist: tribal alienation, displacement for mines and dams, unimplemented forest and land rights, poor services and exploitation by contractors and officials.
  • Shrinking but entrenched: only 46 districts reported LWE violence in 2021 against 96 in 2010 (MHA), yet a hard core in areas such as Dandakaranya and Jharkhand still uses forest terrain and IEDs to inflict losses on security forces.
  • Finance and support: extortion of contractors and mining interests funds the movement, and urban support networks supply ideology and logistics.
  • Rights concerns: operations that harm civilians or misuse the law deepen alienation and feed the insurgents' narrative.

A multilayered strategy

  • Security layer: intelligence-led joint operations by State and central forces, better-trained and equipped State police, fortified posts and the SAMADHAN principles, including actionable intelligence, technology and cutting access to finance.
  • Development layer: roads, mobile connectivity, schools, health and banking in affected districts, with the Aspirational Districts programme and central assistance for LWE areas.
  • Rights and governance layer: implement the Forest Rights Act and PESA, fair land acquisition and rehabilitation, accountable local administration and quick redress of tribal grievances.
  • Outreach layer: dialogue, an attractive surrender and rehabilitation policy, community policing and counter-narrative, and choking the flow of funds and arms.

Sustained security pressure, visible development and rights delivery, and the trust of local communities together can end the movement's appeal.
