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.

It asks 2 things — answer each

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

Open with · Public Private Partnership (PPP) is a long-term contract in which a private partner finances, builds and operates a public asset while the government keeps ownership and sets service standards; India's infrastructure needs run far ahead of its budgets.

Cover

Why PPP: limited fiscal space, private technology and lifecycle maintenance, and risk sharing; the Kelkar Committee (2015) called optimal risk allocation its dominant concern.
Bankable revenue: user charges and commercial rights; Kelkar also urged independent regulators with a unified mandate and quick dispute resolution.
Station model: a developer rebuilds the station and recovers cost by commercial use of surplus land and air space on a long lease; Railways keeps ownership.
Progress: Rani Kamalapati (Habibganj) station, Bhopal, dedicated in November 2021, was redeveloped in PPP mode as a green building with modern amenities.
Limits: thin bidder interest outside big cities, uncertain commercial returns, delays in land and approvals; safeguards: transparent concessions, regulated charges, 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 · With the Amrit Bharat Station Scheme (2023) covering 1,275 stations, PPP will scale only if risks are shared fairly and disputes settled quickly, as the Kelkar Committee urged, with fares and passenger standards kept in public hands.

Kelkar Committee (2015) on revisiting and revitalising the PPP model: optimal allocation of risk across stakeholders was its dominant concern, and poor risk allocation a major cause of PPP failures.PIB (28 December 2015): Report of the Committee on Revisiting and Revitalising the PPP Model of Infrastructure Development, chaired by Dr V. Kelkar, released ↗“The dominant, primary concern of the Committee was the optimal allocation of risks across PPP stakeholders. Inefficient and inequitable allocation of risk in PPPs can be a major factor in PPP failures, ultimately hurting the citizens of India.”
Kelkar Committee (2015): independent regulators with a unified mandate across infrastructure sub-sectors are critical for sectors going in for PPPs.PIB (28 December 2015): Kelkar Committee report on the PPP model released ↗“The Committee cannot overstate the criticality of setting up of independent regulators in sectors that are going in for PPPs.

Model answer· 220words · Minimalist IAS

Public Private Partnership (PPP) is a long-term contract in which a private partner finances, builds and operates a public asset while the government keeps ownership and service standards. India's infrastructure needs run far ahead of its budgets, which is why PPP matters even for railway stations.

Why PPP is required in infrastructure projects

Fiscal space: budgets compete with health and education, so private finance closes the infrastructure gap faster.
Efficiency: private technology, lifecycle maintenance and performance-linked payments that departmental execution often lacks.
Risk sharing: the Kelkar Committee (2015) called optimal allocation of risk its dominant concern, since unfair risk-sharing causes PPP failures; it also urged independent regulators.

GS Paper III 2022 · Q2

10 marks · 150 words Inclusive growth X-Ray · Core #4

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.

It asks 2 things — answer each

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

Open with · Three decades of market-led growth since 1991 cut poverty, yet the gains were uneven across regions, sectors and classes; whether a market economy can grow inclusively depends on the rules and public services built around it.

Cover

Possible, not automatic: competition, enterprise and jobs after 1991 raised incomes and cut poverty, but unevenly across regions, sectors and classes.
Market failures: markets under-provide public goods, bypass those without assets, skills or credit, and concentrate wealth and market power.
Inclusion is engineered: public investment in health, education and skills, social protection and progressive taxation, as the Directive Principles (Articles 38 and 39) direct.
Access at scale: PMJDY had banked 46.25 crore people by August 2022 with Rs 1,73,954 crore in deposits; RBI's FI-Index rose to 56.4 in March 2022 from 53.9.
Growth link: savings enter the formal system, credit reaches MSMEs, women and farmers, and JAM plus UPI make leak-proof DBT, micro-insurance and pensions possible.
Caveat: dormant accounts, thin small-borrower credit and the digital divide mean inclusion must be measured by usage, not accounts opened.

Close with · The market is a good engine but a poor steering wheel; financial inclusion, which the Finance Minister in 2022 called a major step towards inclusive growth, must now turn 46 crore accounts into credit, insurance and enterprise.

GS Paper III 2022 · Q3

10 marks · 150 words Farm subsidies, MSP, PDS & food security

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.

It asks 2 things — answer each

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

Open with · The National Food Security Act, 2013 entitles three-fourths of rural and half of urban Indians to subsidised grain, yet the Shanta Kumar Committee (2015) found PDS leakages of 40 to 50%, and 60 to 70% in some States.

Cover

Targeting: inclusion and exclusion errors, ghost and duplicate ration cards, and stale lists that miss migrants and the newly poor.
Leakage: diversion to the open market, short-weighing and corruption at fair price shops; the Shanta Kumar Committee called TPDS leakages unacceptably high.
Supply chain and nutrition: storage and transport losses, poor-quality grain, procurement concentrated in a few States, unviable shop margins and a cereal-heavy basket.
Technology: end-to-end computerisation; 99.8% of 5.34 lakh fair price shops run on ePoS devices and 19.5 crore ration cards are digitised on transparency portals (2022).
Portability: One Nation One Ration Card, complete across all 36 States/UTs when Assam joined in June 2022, lets migrants draw rations anywhere.
Accountability and structure: social audits, vigilance committees, State Food Commissions and grievance officers; the Committee's option of cash transfers in large cities; millets and pulses; modern FCI storage.

Close with · Clean lists, tracked grain and citizen oversight can cut leakage and fiscal cost together, making the PDS the delivery arm of SDG 2: end hunger and achieve food security.

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.

It asks 2 things — answer each

What: the natural processes that break cellulose down: fragmentation, leaching, catabolism by microbial enzymes and aerobic respiration, before it yields carbon dioxide and water
What: the other pathways and end products: anaerobic decay by methanogens, humification and mineralisation, fire and fossil carbon

Open with · Cellulose, a long chain of glucose units and the most abundant plant polymer, forms most of the detritus on soil; NCERT names the steps returning it to the air as fragmentation, leaching, catabolism, humification and mineralisation, acting together.

Cover

Fragmentation: detritivores such as earthworms and termites shred leaves and wood into smaller particles, exposing more surface to microbes.
Leaching: water-soluble inorganic nutrients move down the soil horizon and precipitate as unavailable salts.
Catabolism: bacterial and fungal cellulase enzymes split cellulose into cellobiose and glucose and then into simpler inorganic substances.
Aerobic respiration: in aerated soil microbes oxidise the glucose to carbon dioxide, water and energy, the main route by which plant carbon returns to the air.
Anaerobic decay: in wetlands, paddy fields, sewage sludge and the rumen, methanogens such as Methanobacterium grow on cellulosic material and release methane with carbon dioxide and hydrogen.
Humification and mineralisation: lignin-rich residues form dark, decay-resistant humus that holds nutrients and is slowly mineralised; fire oxidises litter fast and buried matter becomes peat and coal.

Close with · These processes close the carbon cycle and sustain soil fertility, though methane from wet decay ties it to climate change; the same methanogens, in biogas plants, turn plant waste into rural energy.

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.

It asks 2 things — answer each

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

Open with · Unlike classical smog of smoke and fog, photochemical smog is a brown, oxidising haze of ground-level ozone formed when sunlight acts on exhaust; its control and the Gothenburg Protocol both target precursors.

Cover

Formation: nitrogen oxides and volatile organic compounds react in strong sunlight to form ozone, peroxyacetyl nitrate (PAN) and aldehydes; stagnant air and temperature inversion trap the haze.
Effects: eye irritation, cough, asthma and lung damage, worst for children and the elderly; damaged crops and forests, cracked rubber, poor visibility, and ozone as a greenhouse gas.
Mitigation: cleaner fuels and tighter vehicle norms, catalytic converters, solvent and petrol-vapour controls, public transport and electric vehicles, smog alerts; the National Clean Air Programme (2019) targets up to 40% lower PM10 in 131 cities by 2025-26.
Gothenburg Protocol, 1999: under the 1979 UNECE Convention on Long-range Transboundary Air Pollution, the Protocol to Abate Acidification, Eutrophication and Ground-level Ozone set national emission ceilings for sulphur dioxide, nitrogen oxides, ammonia and VOCs from 2010.
First multi-pollutant, multi-effect protocol; the 2012 amendment, in force since 2019, added emission-reduction commitments for 2020 and beyond and brought in fine particulate matter (PM2.5).

Close with · Smog forms in the air from precursors; coordinated control of nitrogen oxides and VOCs, Gothenburg's multi-pollutant logic that NCAP applies to 131 cities, is the surest cure.

It asks 3 things — answer each

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

Open with · IMD terms a rain event a cloudburst when a station receives 10 cm of rain in one hour; over a few tens of square kilometres it turns, within minutes, into flash floods and debris flows.

Cover

Mechanism: warm, moist monsoon air forced up steep slopes (orographic lift) builds towering cumulonimbus clouds whose strong updrafts hold large droplets aloft.
Release: when the updraft collapses, or clouds are hemmed in by narrow valleys, the stored water falls at once; a western disturbance meeting the monsoon can intensify it.
Occurrence: mostly in the monsoon on mid-elevation slopes of the Himalayan belt (Uttarakhand, Himachal Pradesh, Jammu and Kashmir, Ladakh) and at times the Western Ghats; mountains are more prone because of orography.
Examples: Amarnath cave area, Jammu and Kashmir, 8 July 2022, flash floods through pilgrims' camps; Kishtwar, Jammu and Kashmir, 28 July 2021, deaths and destroyed houses.
Impact multipliers: deforestation, road-cutting and construction on fragile slopes and riverbeds turn heavy rain into flash floods, landslides and debris flows.
Response: IMD says cloudbursts are very hard to predict and need a dense radar network; six Doppler radars were added in 2022, including Surkanda Devi (Uttarakhand) and Banihal Top (J&K), taking the total to 35; nowcasting, hazard zoning and regulated construction.

Model answer· 358words · Minimalist IAS

India's recent growth has been productivity-led: output per worker rose much faster than the number of workers. The Economic Survey 2023-24 estimates that the economy must create about 78.5 lakh non-farm jobs a year till 2030 merely to absorb its rising workforce; growth by itself has not delivered them.

Why recent growth was led by labour productivity

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.
Capital deepening: mechanisation, automation and IT in the formal sector let firms expand output with few new hires.
Services-led growth: high-productivity finance and software grew fastest, yet they employ few workers.
Structural shift: 45.8% of workers were still in agriculture in 2023 (Economic Survey 2023-24); each worker who leaves the farm lifts average productivity even when the new job is informal.
Result: a thin formal segment with rising productivity beside a large low-productivity informal sector and disguised unemployment on farms; the usual-status unemployment rate was only 3.2% in 2023-24 (PLFS) because subsistence work counts as employment.

It asks 2 things — answer each

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
Explain how shifting subsidies from fossil fuels to renewables helps achieve the objective

Open with · India's updated NDC (August 2022) commits to about 50% of installed electric power capacity from non-fossil sources by 2030, a capacity target, not half 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.

India's updated NDC (August 2022) promises 'about 50 percent cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030': a target for power capacity, not for half of all energy used, so the answer differs for the two.

Will India meet 50 percent from renewables by 2030: a two-part answer

Capacity: yes, already met. On 30 June 2025 non-fossil sources (renewables, large hydro, nuclear) stood at 242.78 GW of 484.82 GW, 50.08% of installed capacity, five years early (MNRE).
Drivers: competitive auctions and falling tariffs, with PM-KUSUM, PM Surya Ghar: Muft Bijli Yojana, solar parks and the National Wind-Solar Hybrid Policy (MNRE, 2025).
Generation lags capacity: solar and wind run for fewer hours than coal plants, so half the capacity is well under half the electricity generated.
Total energy: no. Transport, industry and cooking still run on oil, coal and gas, so renewables' share of all energy used stays far below their share of power capacity.
Constraints: intermittency without storage, transmission and grid integration, land, weak DISCOM finances, import dependence for modules and coal's baseload role.

Measure	Status	Verdict
Non-fossil installed capacity	50.08% (June 2025)	Met early

Model answer· 369words · Minimalist IAS

The NABCONS study (2022) for the Food Processing Ministry found post-harvest losses of 6-15% in fruits and 5-12% in vegetables, against under 1% in milk with its mature cold chain. These losses, and the farmer's small share of the consumer's rupee, come from weak links before produce reaches the mandi (upstream) and after it leaves (downstream).

Upstream bottlenecks: farm, aggregation and mandi

Fragmented supply: small, scattered holdings sell tiny lots with no grading, standards or aggregation, leaving farmers little bargaining power.
Information and credit: limited price information and credit 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, trader cartels and delayed payments.
Regulation: stock limits and export curbs under the Essential Commodities Act and sudden trade-policy swings deter private storage and investment and add to price volatility.

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.

It asks 2 things — answer each

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

Open with · An Integrated Farming System combines crops with livestock, fish, poultry, bees, trees and biogas so that one enterprise's waste feeds another; with holdings averaging 1.08 hectares (Agriculture Census 2015-16), it matters most for the small farmer.

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 a one-hectare farm, integration rather than intensification is the route to the stable, higher income that doubling farmers' income set out, and deserves the first claim on extension effort.

Model answer· 364words · Minimalist IAS

An Integrated Farming System (IFS) combines crops with livestock, fish, poultry, bees, trees and biogas on one farm, so that the waste of one enterprise becomes the input of another. With the average operational holding down to 1.08 hectares (Agriculture Census 2015-16), such whole-farm integration matters most for the small farmer.

What an Integrated Farming System is

Resource recycling: crop residue becomes fodder, dung becomes manure and biogas, and pond water irrigates crops, so little leaves the farm as waste.
Deliberate design: an intentional integrated system pursues several aims at once: production, profit, cost-cutting through recycling, family nutrition, sustainability, employment and equity (Agriculture Ministry, 2018).
Location-specific models: ICAR, with 25 State Agricultural Universities under its All India Coordinated Research Project, has developed 45 IFS models for 23 States and one UT, covering all 15 agro-climatic regions.

Launched on 25 December 2021, the James Webb Space Telescope (JWST) is led by NASA with significant contributions from the European and Canadian space agencies. It extends Hubble's discoveries with longer wavelength coverage and far greater sensitivity, which is what makes it superior to every space telescope before it.

Unique features that make Webb superior to its predecessors

Mirror: a 6.5 m primary mirror of 18 gold-coated hexagonal segments, about 2.75 times Hubble's diameter and roughly six times its light-collecting area (NASA).
Infrared vision: optimised for near- and mid-infrared light, it sees through dust and catches the red-shifted light of the earliest galaxies that Hubble, mostly an optical and ultraviolet telescope, cannot.
Cold operation: a five-layer sunshield the size of a tennis court, each layer cooler than the one below, keeps the telescope's own heat from swamping faint infrared signals.
Orbit: it circles the Sun-Earth L2 point about 1.5 million km away, far from Earth's heat and glare, unlike Hubble at about 600 km; the price is that it cannot be serviced.

What approaches Indian manufacturers adopted to produce COVID-19 vaccines

Open with · A vaccine trains the adaptive immune system to recognise a pathogen without causing the disease; under Mission COVID Suraksha (Rs 900 crore) India turned this principle into four indigenous vaccines in two years.

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.

Model answer· 332words · Minimalist IAS

A vaccine trains the adaptive immune system to recognise a pathogen without causing the disease, so that real exposure meets a faster and stronger response. Under Mission COVID Suraksha (Rs 900 crore, Atmanirbhar Bharat 3.0), India turned this principle into four indigenous vaccines in two years (PIB, 2023).

Basic principle behind vaccine development

Antigen without disease: a harmless form or part of the pathogen (the antigen) prompts adaptive immunity and leaves memory cells, so infection later meets a rapid secondary response.
Platform choice: live attenuated, inactivated, subunit, toxoid, viral-vector, DNA and mRNA vaccines differ only in how they present the antigen.
Population effect: when enough people are immune, transmission falls and even the unvaccinated gain herd protection.

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.

Coastal erosion is the loss of shoreline to waves, currents and storms. The National Centre for Coastal Research found about a third of India's mainland coast, 33.6% over 1990-2018, eroding to varying degrees, and it hits coastal communities, fishermen most of all (PIB, 2023).

Causes of coastal erosion in India

Natural forces: wave action, longshore currents, storms and cyclones, tides and sea-level rise.
Sediment starvation: dams and river-sand mining cut the sand that rivers once delivered to the coast.
Structures on the shore: ports, harbours and breakwaters block the natural drift of sand, and seawalls shift erosion to the next stretch.
Lost buffers: destruction of mangroves and dunes, and construction on the beach itself.

Model answer· 372words · Minimalist IAS

Cyber security protects the networks, devices and data of government, business and citizens. A national strategy binds its technical, legal and institutional elements into one plan with clear accountability; India has many of the elements, not yet the strategy.

The different elements of cyber security

Technical: securing networks, applications, endpoints and the cloud; encryption; backup and recovery.
Human: user awareness, a skilled workforce and a security culture inside organisations.
National: protection of critical information infrastructure, law and policy, institutions, research and international cooperation.

GS Paper III 2022 · Q20

15 marks · 250 words Development & extremism

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.

It asks 2 things — answer each

Discuss the emerging issues in tackling Naxalism, seen as a social, economic and developmental problem with a violent security face
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; LWE-affected districts fell from 126 to 38 by April 2024 and incidents by 77% over 2009-2021 (MHA), yet the grievance remains the disease.

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 · Security pressure, visible development, rights delivery and community trust can end the movement's appeal; the test of the March 2026 deadline is whether schools, roads and PESA gram sabhas hold the ground after it.

Model answer· 370words · Minimalist IAS

Naxalism thrives where poverty, land and forest grievances and weak governance meet. LWE-affected districts fell from 126 to 38 by April 2024 and incidents by 77% over 2009-2021 (MHA), yet violence is only the symptom; the grievance is the disease, so the response must go beyond policing.

The 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: six most-affected districts were left by April 2024, Bijapur, Kanker, Narayanpur and Sukma in Chhattisgarh, West Singhbhum in Jharkhand and Gadchiroli in Maharashtra (MHA, 2024), where a hard core still uses forest terrain and IEDs.
Finance and support: extortion from contractors and mining interests funds the movement, and urban networks supply ideology and logistics.
Rights concerns: operations that harm civilians or misuse the law deepen alienation and feed the insurgents' narrative.
The deadline test: the Government's target of ending Naxalism by 31 March 2026 raised the stakes for due process in the final phase.

✏️ Map to sketch in the exam · LWE-affected districts, April 2024

districts: Bijapur (Chhattisgarh), Kanker (Chhattisgarh), Narayanpur (Chhattisgarh), Sukma (Chhattisgarh), West Singhbhum (Jharkhand), Gadchiroli (Maharashtra) = most-affected (MHA 2024)
