GS Paper III 2017

Potential growth is the pace an economy can sustain without overheating; it rises with the capital, labour and productivity a country can bring together.

Case for the savings rate

• Growth models such as Harrod-Domar tie growth to the savings rate divided by the capital-output ratio; high domestic savings finance investment without heavy foreign borrowing.

Why savings alone are not enough

• Savings lift growth only when turned into productive investment; funds parked in gold and property, or a high incremental capital-output ratio, blunt the effect.
• Physical capital runs into diminishing returns; without productivity gains, more of the same investment yields less growth.

Other factors for growth potential

• Human capital: a young workforce raises potential only with health, education and skills; the demographic dividend is an opportunity, not a guarantee.
• Productivity and technology: total factor productivity, innovation and the shift of workers from farms to organised-sector jobs explain much of East Asia's sustained growth.
• Infrastructure: power, roads, ports and credit lower costs and raise the return on every rupee invested.
• Institutions and policy: contract enforcement, stable macroeconomic policy and a deeper financial sector reduce risk.
• Openness and reform: trade, FDI and product and labour market reform move resources to their best uses.

Savings are necessary but not sufficient: they supply the fuel, while skills, technology, infrastructure and institutions decide how far the vehicle travels.

India exports mostly capital- and skill-intensive goods, while apparel, footwear, leather and toys, which could employ millions, have lost ground to Bangladesh, Vietnam and China.

Why labour-intensive exports failed

• Labour rules: Chapter V-B of the Industrial Disputes Act, 1947 needs government permission for retrenchment and closure in units of 100 or more workers, so firms stay small or mechanise.
• Scale: fragmented, sub-scale units cannot fill large orders, adopt modern technology or absorb compliance costs.
• Logistics: unreliable power, congested ports and high transaction costs make delivery slower and dearer than in competitor countries.
• Skills and credit: low skills and costly finance cap quality and productivity.
• Trade terms: fewer trade agreements than rivals, inverted duties and a strong rupee erode price competitiveness; Bangladesh, a least developed country, enjoys duty-free access to the EU.

Measures for labour-intensive exports

• Labour flexibility: the June 2016 apparel package brought fixed-term employment, higher overtime caps and government payment of the employer's EPF share for new low-wage workers; extend it to leather, footwear and toys.
• Scale: plug-and-play parks and common facilities for apparel and leather clusters, plus cheaper credit for small units.
• Trade: FTAs with major markets, timely refund of state levies, corrected inverted duties and faster customs.
• Skills and women: sector training, plus hostels and transport for women, who form the bulk of garment workers.

Labour-intensive exports need flexible labour rules, world-class logistics and a skilled workforce, so that jobs and exports grow together.

Since the mid-2000s the Government has developed large airports through joint-venture companies: a private developer holds the majority, with the Airports Authority of India (AAI) and State governments as minority partners.

Development through joint ventures

• Brownfield: Delhi (DIAL) and Mumbai (MIAL) went to private-led joint ventures in 2006, with AAI as a minority partner earning a share of gross revenue.
• Greenfield: Bengaluru (BIAL) and Hyderabad (GHIAL) opened in 2008 as joint ventures of private developers with AAI and the State governments.
• Other model: Kochi (CIAL, 1999), a State-promoted public company funded by non-resident and institutional investors, showed an airport can be built without Union funds.
• Gains: modern terminals, rapid traffic growth, better service, non-aeronautical revenue and less strain on the public purse.

Challenges for the authorities

• Tariffs: disputes over user development fees and aeronautical charges exposed the need for an independent regulator, leading to the Airports Economic Regulatory Authority (AERA) in 2009.
• Land and audit: commercial use of airport land, revenue-share and concession-term disputes, and audit concerns over the value of concessions.
• Finance: project delays, cost overruns and highly indebted developers make fair bidding and close monitoring essential.
• Cross-subsidy: AAI relies on a few profitable airports to support loss-making regional ones, so losing its best airports strains regional connectivity.

PPP joint ventures modernised India's big airports; the next step is transparent bidding, credible tariff regulation and a viable model for regional airports.

After independence India moved from ship-to-mouth imports under PL-480 to self-sufficiency in foodgrains, and then diversified into milk, fish, oilseeds and horticulture through campaign-style 'revolutions'.

The revolutions

• Green Revolution (mid-1960s): high-yielding wheat and rice, fertilisers, irrigation and assured procurement prices, mainly in Punjab, Haryana and western Uttar Pradesh; foodgrain output reached a record 275.68 million tonnes in 2016-17.
• White Revolution (Operation Flood, 1970): cooperative dairying under the NDDB, led by Verghese Kurien, made India one of the largest milk producers.
• Blue (fisheries), Yellow (oilseeds), Golden (horticulture), Pink (meat and prawns) and Silver (eggs and poultry) revolutions widened the food basket.

Food security

• Surplus grain built buffer stocks and fed the public distribution system; famine deaths and import dependence ended, and the National Food Security Act, 2013 could promise subsidised grain to two-thirds of the population.
• Cheaper milk, eggs, fish and vegetables improved nutrition beyond calories.

Poverty alleviation

• Higher yields raised farm incomes and rural wages; dairy gave small and landless households, especially women, a steady daily cash income.
• Lower food prices raised the real incomes of the poor, while agro-processing and input industries created non-farm jobs.
• Limits: gains were regional and crop-specific; groundwater depletion, soil fatigue and neglect of pulses and rain-fed areas call for M.S. Swaminathan's 'evergreen revolution'.

These revolutions gave India food security and raised rural incomes; the next phase must be sustainable, regionally balanced and built around small farmers.

ICAR-CIPHET (2015) estimated harvest and post-harvest losses at about Rs 92,651 crore a year; small processing units near the farm could turn that loss into income, yet few get set up.

Reasons for poor acceptance

• Awareness and skills: farmers rarely know the technology, and trained operators, extension workers and repair services are scarce.
• Finance: banks treat small units as risky, collateral is scarce and interest is high.
• Infrastructure: unreliable power, poor roads and no cold chain; seasonal, scattered raw material keeps units below capacity.
• Markets and compliance: weak market linkage and branding, competition from large firms, and costly licensing and food-safety compliance.
• Technology: machinery is designed for large plants, with little suited to village-scale units.

How processing uplifts poor farmers

• Value addition and less waste raise the price farmers receive and spread income across seasons instead of one distress sale.
• Local jobs for women and landless families, and a market close to the farm, shift households from farm to non-farm income.
• Ownership through farmer producer organisations and cooperatives keeps processing margins in the village; Amul shows the model at scale.
• Steadier incomes improve nutrition, schooling and bargaining power, and reduce distress migration.

Way forward

• Cluster-based units, cheap credit, common facilities and market tie-ups under the Kisan SAMPADA scheme (2017).

Small, farmer-owned processing units linked to markets, credit and common facilities can turn produce into income and lift rural households.

Stem cells are unspecialised cells that renew themselves and can develop into specialised cells such as blood, skin or corneal cells, which makes them the body's repair kit.

What stem cell therapy is

• Stem cells taken from bone marrow, umbilical cord blood or tissue, or made by reprogramming adult cells into induced pluripotent stem cells (Shinya Yamanaka, Nobel Prize 2012), are given to replace or repair damaged cells and tissues.
• Established uses: blood stem cell transplant for leukaemia and thalassaemia; limbal stem cells to rebuild a damaged cornea; cultured skin cells for severe burns.

Advantages over other treatments

• Cure, not control: it replaces defective or lost tissue, so it can cure conditions that drugs and transfusions only manage.
• Lower rejection: the patient's own cells avoid immune rejection and lifelong immunosuppressants.
• Less dependence on scarce donor organs and on repeated transfusions, which carry infection and iron-overload risks.
• New options for diseases with few treatments, such as some blood, eye and spinal disorders, with fewer long-term side effects than drugs.

Cautions

• Beyond blood stem cell transplants and a few proven uses, most therapies remain experimental; unproven clinics, high cost and tumour risk need regulation, so the ICMR-DBT National Guidelines for Stem Cell Research (2013, revised 2017) allow clinical use only within approved trials.

Stem cell therapy promises repair rather than symptom control, but it should reach patients through proven, regulated trials rather than commercial shortcuts.

A crewed flight is a different order of challenge from a probe: the payload must survive, and so must the crew.

Technological obstacles

• Human-rated launcher: a rocket certified for near-zero failure tolerance; GSLV Mk III, whose first developmental flight was in June 2017, must prove itself over repeated launches.
• Crew module and return: heat shield, controlled re-entry, parachute deceleration and sea recovery; ISRO tested these with SRE-1 (2007) and the CARE capsule (2014).
• Life support: air, water, temperature and radiation control in a sealed cabin, and a crew escape system for launch aborts, neither flight-tested by 2017.

Logistical obstacles

• Astronaut selection and training, space medicine, crewed mission control, a global tracking network and recovery ships.
• Cost: a decade-long budget commitment competes with development needs, and one failure costs lives and prestige.

Critical examination

• The barrier is certification, reliability and funding, not raw capability: ISRO has a heavy launcher, re-entry experience and deep-space navigation from Chandrayaan-1 and the Mars Orbiter Mission.
• The case for going ahead: spin-offs in materials, medicine and electronics, prestige, inspiration for youth and space diplomacy; partnerships can fill gaps in training and life support.

The obstacles are demanding but manageable; a phased, safety-first programme with partnerships can take India from robotic to human spaceflight (since then, ISRO's Gaganyaan programme envisages a three-member crew in a 400 km orbit for three days, returning to Indian waters).

India's rain is concentrated in a few monsoon months and uneven across basins, so some regions flood while others face drought; the National Perspective Plan (1980) proposed 30 links, the Supreme Court in 2012 directed time-bound implementation, and Ken-Betwa became the first link taken up.

Advantages

• Irrigation and drought relief: water from surplus basins reaches dry regions, expanding irrigated area and stabilising farm output.
• Flood moderation: storages and diversions on the Ganga-Brahmaputra system can reduce floods in Bihar, Assam and eastern Uttar Pradesh.
• Other gains: drinking water, hydropower, inland navigation, groundwater recharge and industrial supply.

Environmental impact

• Submergence and displacement: dams and canals drown forests and villages; the Ken-Betwa link would submerge part of the Panna tiger landscape.
• River health: altered flows, less silt and freshwater reaching deltas and estuaries, salinity ingress, and damage to fish migration and wetlands.
• Uncertain science: the idea of a permanently 'surplus' basin is contested, and climate change is altering rainfall and glacier-fed flows.
• Other concerns: huge cost and long gestation, inter-State water disputes, and effects on neighbours such as Bangladesh and Nepal.

Way forward

• Take up each link only after independent environmental and social assessment, once cheaper alternatives such as watershed development, rainwater harvesting, drip irrigation and demand management have been tried.

River linking can ease scarcity and floods, but only with scientific study of each link, environmental and social safeguards and consensus among States.

As banking, power, transport and government services move online under Digital India, cyber attacks can steal data, freeze services and even damage critical infrastructure.

Potential threats

• Malware and ransomware: WannaCry (2017) locked systems worldwide; phishing, denial-of-service attacks and financial fraud target banks and citizens.
• Critical infrastructure: attacks on power grids, telecom, banking and transport can paralyse the economy; state-sponsored espionage and cyber terrorism threaten national security.
• Data theft: the 2016 debit card breach forced Indian banks to block and reissue cards on a large scale.
• Vulnerabilities: imported hardware and software, weak passwords, low awareness, shortage of skilled staff and poor incident reporting.

Security framework

• Law: the Information Technology Act, 2000 (amended 2008) penalises hacking (Section 66) and cyber terrorism (Section 66F), shields designated 'protected systems' (Section 70) and makes firms liable for lax data security (Section 43A).
• Institutions: CERT-In for incident response, NCIIPC for critical information infrastructure, a National Cyber Security Coordinator, and the National Cyber Security Policy, 2013.
• Practice: RBI's cyber security framework for banks (2016), sectoral audits, police cyber-crime cells and the Cyber Swachhta Kendra (2017) for cleaning infected devices.
• Gaps: no data protection law in 2017 (the Justice B.N. Srikrishna committee was set up that year), few trained officials, and India outside the Budapest Convention on cybercrime.

Strong law, alert institutions, skilled people and aware citizens must work together, because the weakest link decides the strength of the chain.

Insurgency in the North-East began with the Naga movement in the 1950s and survives because political, ethnic, economic and geographic factors keep feeding it.

Identity and politics

• Fear of losing land, culture and political voice drives demands for autonomy or separate homelands; even after Statehood, the Sixth Schedule and autonomous councils, new groups keep emerging.
• Migration and land: influx from Bangladesh and pressure on tribal land fed the Assam agitation and the Assam Accord (1985), and ULFA (1979) drew on the same anxiety.

Geography and external links

• The narrow Siliguri corridor is the only land link to the rest of India, while porous borders with Myanmar, Bangladesh and Bhutan offer camps, arms routes and sanctuary; NSCN-K left its ceasefire in 2015 and operates from Myanmar.
• Links with the arms and drug networks of the Golden Triangle help groups regroup and fund themselves.

Economy and governance

• Poor connectivity, few jobs and weak services leave youth open to recruitment; extortion and parallel 'taxation' turn insurgency into a livelihood.
• Corruption, slow implementation of accords, weak justice and alleged excesses under AFSPA (1958) create resentment that groups exploit.

Fragmentation

• Peace deals with one faction, such as the 1997 NSCN-IM ceasefire or the 2003 Bodo Accord, leave rivals outside, and turf wars among groups keep violence alive.

Lasting peace needs political settlements honoured in full, as the Mizo Accord (1986) showed, together with border management, faster development and clean local governance.

The Union Budget 2017-18, presented on 1 February with the Railway Budget merged into it, grouped its proposals under a ten-theme agenda summed up as 'Transform, Energise and Clean India' (TEC India).

Transform: farmers, villages, the poor

• Agricultural credit target raised to a record Rs 10 lakh crore, with special effort for under-served eastern States; a dedicated micro-irrigation fund with NABARD.
• MGNREGA allocation raised to Rs 48,000 crore, its highest ever, alongside larger outlays for rural roads and housing.
• Mission Antyodaya to bring one crore households out of poverty and make 50,000 gram panchayats poverty-free by 2019.
• Youth and the poor: new skill centres, education reform and higher outlays on health and sanitation.

Energise: infrastructure and enterprise

• Record capital outlay for roads, ports and railways; a Rashtriya Rail Sanraksha Kosh of Rs 1 lakh crore over five years for passenger safety.
• Affordable housing given infrastructure status, opening cheaper long-term finance for low-cost homes.
• Foreign Investment Promotion Board abolished, since over 90 per cent of FDI already came through the automatic route; incentives for BHIM-based digital payments.

Clean: black money and political funding

• No cash transaction above Rs 3 lakh, as the Special Investigation Team on black money advised; cash donations to charitable trusts capped at Rs 2,000.
• Cash donations to political parties limited to Rs 2,000 per donor, donations by cheque or digital mode, and electoral bonds announced.

Prudent finance and assessment

• Fiscal deficit pegged at 3.2 per cent of GDP for 2017-18 with 3 per cent promised for the next year; the advanced Budget date lets spending start on 1 April.
• The measures aim squarely at rural demand, jobs and transparency, but outcomes hinge on the quality of MGNREGA assets, States' capacity to spend, credit reaching small rather than large farmers, and revenue buoyancy in the year GST was rolled out.
• Electoral bonds curb cash but keep donors anonymous, so the claim to 'clean' politics depends on how the scheme is designed.

The Budget married welfare, infrastructure and clean-economy measures within a credible fiscal frame; whether it transformed, energised and cleaned India rests on delivery, not on allocations.

After 1991 services became the engine of India's growth, while industry, and manufacturing in particular, kept roughly the same share of GDP, unlike the manufacturing-led take-off of East Asia.

Why industry lagged

• Infrastructure deficit: unreliable power, congested ports and costly logistics raised costs and delayed projects, a burden that software and finance could sidestep.
• Factor markets: rigid labour laws pushed firms to stay small or capital-intensive; land acquisition was slow and contested; multiple clearances stretched gestation periods.
• Competition and finance: tariff cuts exposed firms to imports before they reached scale; weak R&D kept technology borrowed; high real interest rates and, after 2011, stressed bank and corporate balance sheets choked credit.
• Structure: a fragmented, informal small-scale sector could not scale up, while services grew on skilled labour and needed far less physical capital.
• Demand shocks: the global slowdown after 2008 hit exports, and private investment stayed weak thereafter.

Recent policy changes

• Make in India (2014): FDI opened in defence, railways and insurance; ease-of-doing-business reforms, online clearances and self-certification; Start-up India and Skill India.
• National Manufacturing Policy (2011): a target of a 25 per cent manufacturing share of GDP by 2022 through National Investment and Manufacturing Zones and corridors such as Delhi-Mumbai.
• GST (July 2017) created one national market and removed cascading taxes; the Insolvency and Bankruptcy Code (2016) allows quick exit and resolution of stressed assets; Sagarmala targets logistics costs.

How far they can help

• Strengths: lower transaction costs, better allocation of capital, foreign technology, scale economies from a common market and formalisation of supply chains.
• Limits: land, labour and power reforms lie largely with the States; bank credit to industry stayed sluggish; skill gaps persist; exports need trade access and a competitive exchange rate; the GST transition and demonetisation disrupted output in the short run.
• Verdict: the changes remove real constraints but are necessary rather than sufficient, and their effect will show only over several years.

Industrial policy now points the right way; a stable tax and regulatory regime, factor-market reform and a credit revival must follow if industry is to lead growth rather than trail it.

Inclusive growth is growth whose benefits reach every section and region through opportunity, not transfers alone; the Eleventh Five Year Plan made 'faster and more inclusive growth' its stated goal.

Salient features

• Broad-based across sectors and regions, raising the incomes of the poor faster than the average.
• Productive employment, not output alone, so that growth absorbs labour.
• Equal access to health, education, finance and infrastructure: equality of opportunity.
• Falling poverty and inequality, with participation of women, Scheduled Castes and Tribes, minorities and backward regions, and social protection for the vulnerable.
• Environmentally sustainable, so that today's gains are not borrowed from the next generation.

Has India experienced it

• Gains: the poverty ratio fell from 37.2 per cent in 2004-05 to 21.9 per cent in 2011-12 (Planning Commission, Tendulkar line); MGNREGA (2005), the National Food Security Act (2013) and Jan Dhan (2014) widened entitlements and financial access.
• Jobs: growth came from capital- and skill-intensive sectors, so employment grew slowly and most workers stayed informal without social security.
• Agriculture: employs nearly half the workforce for a shrinking share of output, with recurrent distress.
• Inequality: wealth concentration rose; the gap between the eastern and central States and the south and west persists; female labour-force participation is low and falling.
• Services: poor learning outcomes and public health, and unequal access to credit and land.
• Verdict: growth reduced poverty but was not inclusive in jobs, quality of services or distribution.

Measures

• Raise farm incomes through irrigation, diversification, market reform and farmer producer organisations.
• Promote labour-intensive manufacturing (textiles, footwear, food processing) with MSME credit and simpler labour rules.
• Build human capital: learning outcomes, primary health care and skilling tied to jobs.
• Fix delivery: direct benefit transfers through Jan Dhan-Aadhaar-mobile to cut leakage, and social security for informal workers.
• Target equity: childcare and safe transport for women, education and credit for SCs, STs and minorities, larger transfers and empowered panchayats for backward districts.

India has grown fast but unevenly; jobs, human capital and leak-proof delivery are the routes to growth that carries everyone along.

The rice-wheat system of the Indo-Gangetic plains delivered the Green Revolution, but four decades of the same two cereals on the same fields have brought yield stagnation and rising input costs, most sharply in Punjab and Haryana.

Why yields are declining

• Soil fatigue: continuous cereal cropping mines nutrients; organic carbon and micronutrients such as zinc fall, and nitrogen used far out of proportion to phosphorus and potash lowers the response to fertiliser.
• Water: flooded paddy draws heavily on groundwater and free power encourages over-pumping, so water tables fall while canal tracts suffer waterlogging and salinity.
• Biotic stress: monoculture builds up pests and diseases and has produced herbicide-resistant Phalaris minor in wheat; stubble burning destroys soil life and fouls the air.
• Climate: terminal heat during grain filling cuts wheat yields, and an erratic monsoon delays paddy transplanting, which squeezes the wheat sowing window.
• Technology plateau: the yield potential of Green Revolution varieties is largely exhausted and new varieties reach farmers slowly.
• Policy lock-in: assured procurement at minimum support prices for rice and wheat makes every other crop the riskier choice.

How diversification stabilises yields

• Soil renewal: pulses in rotation fix nitrogen and add organic matter; deep-rooted crops improve soil structure, so cereal yields recover in the following season.
• Breaking cycles: a change of crop interrupts pest, disease and weed cycles and reduces pesticide use.
• Water balance: maize, pulses and oilseeds need far less water than paddy, easing groundwater decline and keeping the system viable.
• Risk spreading: a mix of crops and horticulture spreads weather and price risk and adds income, so one failed crop no longer sinks the farm.
• Policy support: the Crop Diversification Programme, run under RKVY since 2013-14 in Punjab, Haryana and western Uttar Pradesh, helps shift paddy area to maize, pulses, oilseeds and agroforestry; it works only where procurement and markets exist for these crops.

Moving part of the rice-wheat area to pulses, oilseeds and horticulture, backed by prices and markets, can restore soil and water health and steady yields across the whole system.

Subsidies on fertiliser, power, water and credit lower farmers' costs, but they also signal what to grow and how much input to use, and so shape cropping decisions across the country.

Effect of subsidies

• Cropping pattern: cheap urea, free or flat-rate power, subsidised canal water and assured procurement pull farmers towards rice, wheat and sugarcane even where water is scarce, as with paddy in Punjab and sugarcane in Maharashtra.
• Crop diversity: pulses, oilseeds and millets lose area to cereals; monocropping narrows the crop base; the urea bias distorts the nitrogen-phosphorus-potash balance and degrades soil.
• Farm economy: subsidies cut costs and steady incomes, but larger irrigated farms capture most of the benefit; overuse raises costs later through deeper pumping and poorer soils; the fiscal burden crowds out public investment in irrigation, research and markets.

Significance for small and marginal farmers

• Crop insurance: the Pradhan Mantri Fasal Bima Yojana (2016) fixes the farmer's premium at 2 per cent for kharif, 1.5 per cent for rabi and 5 per cent for annual commercial and horticultural crops, with the balance paid by government; it reduces distress borrowing after weather shocks and lets small farmers try higher-value crops, though delayed claims and low awareness limit its reach.
• Minimum support price: a floor that guards against a post-harvest price crash and, where procurement exists, gives income certainty; yet small farmers with little marketable surplus and distant mandis often sell to traders below MSP, and procurement is concentrated in a few States and crops.
• Food processing: cuts post-harvest losses, adds value and provides assured buyers through contract farming and producer organisations; it raises the farmer's share of the consumer price and creates non-farm jobs near villages, which matters where holdings are too small to live on.

Reform direction

• Move to direct income support, bring urea under nutrient-based pricing, extend procurement to pulses and oilseeds, and organise small holders into farmer producer organisations linked to processors.

Support should protect the small farmer without dictating the crop; insurance, wider price support and processing can do that better than open-ended input subsidies.

India's nuclear programme, shaped by Homi Bhabha, was planned around scarce uranium and abundant thorium, which produced a three-stage strategy and a lasting emphasis on self-reliance.

Growth of nuclear science and technology

• Foundations: Tata Institute of Fundamental Research (1945), Atomic Energy Commission (1948) and Department of Atomic Energy (1954); Apsara at Trombay (1956) was Asia's first research reactor, followed by CIRUS (1960).
• Power generation: Tarapur (1969) with imported boiling water reactors, then an indigenous line of pressurised heavy water reactors run by NPCIL, scaled from 220 MWe to 540 MWe and 700 MWe designs.
• Full fuel cycle: uranium mining at Jaduguda, heavy water plants, fuel fabrication and reprocessing gave India command of the closed cycle.
• Strategic capability: the 1974 and 1998 tests; the sanctions that followed deepened indigenisation.
• Applications: radioisotopes for cancer therapy and diagnostics, radiation processing of food, mutation-bred crop varieties, desalination and industrial radiography.
• Opening up: the 2008 civil nuclear agreement with the United States, IAEA safeguards and the Nuclear Suppliers Group waiver allowed uranium and reactor imports; Kudankulam was built with Russia.
• Fast reactors: the Fast Breeder Test Reactor at Kalpakkam (1985) built experience for the 500 MWe Prototype Fast Breeder Reactor of BHAVINI (since then, the PFBR attained first criticality on 6 April 2026).

Advantage of the fast breeder programme

• More fuel out than in: the uranium-238 blanket converts into plutonium-239, so the reactor breeds more fissile material than it consumes.
• Multiplies uranium: it draws far more energy from the same natural uranium, stretching limited domestic reserves and cutting import dependence.
• Gateway to thorium: a thorium blanket breeds uranium-233, the fuel of the third stage, unlocking India's very large thorium reserves for long-term energy security.
• Closed cycle: reprocessing and recycling reduce long-lived waste, and the technology is largely indigenous.
• Caveats: sodium coolant demands rigorous safety, costs are high and the prototype took long to commission.

Fast breeders link today's heavy water fleet to a thorium future; if safety and cost are mastered, they give India an energy base largely free of imported fuel.

A monsoon-dependent economy, a coastline of about 7,500 km and a glaciated Himalaya make India one of the countries most exposed to a warming climate.

Impact on India as a whole

• Monsoon and farming: more variable rain, fewer rainy days with heavier bursts, floods and droughts in the same year; heat during grain filling hurts wheat and rain-fed kharif crops suffer, threatening food security and farm incomes.
• Water: stress on rivers and groundwater sharpens inter-State and rural-urban conflict.
• Health: more intense heat waves, malaria and dengue spreading to new areas, and lost productivity for outdoor workers.
• Economy and ecology: damage to roads, power and cities from extreme events, higher cooling demand, forced migration; coral bleaching, shifting forest types and species loss; a large poor and farm-dependent population has little capacity to adapt.

Himalayan states

• Glaciers and rivers: retreat first swells and then reduces the flows of the Indus, Ganga and Brahmaputra, disturbing irrigation and hydropower downstream.
• Hazards: glacial lake outburst floods, cloudbursts and landslides, as in the Kedarnath disaster of 2013; longer dry spells raise forest-fire risk, as in Uttarakhand in 2016.
• Livelihoods: apple belts in Himachal Pradesh shift uphill, snow-dependent tourism turns uncertain, and fragile roads are repeatedly cut.

Coastal states

• Sea-level rise: erosion, submergence of low islands in the Sundarbans and Lakshadweep, and saline intrusion into the Ganga, Mahanadi, Krishna-Godavari and Cauvery deltas, ruining farmland and drinking water.
• Cyclones and surges: stronger storms, as with Phailin (2013) and Hudhud (2014), threaten Odisha, Andhra Pradesh, Tamil Nadu and Gujarat; urban floods as in Chennai (2015) grow costlier.
• Fisheries and mangroves: warming shifts fish stocks and bleaches corals, hitting fishing communities.

• The National Action Plan on Climate Change (2008) with its mission on the Himalayan ecosystem, State action plans, cyclone early warning, climate-resilient crops, and India's 2015 pledge to cut the emissions intensity of GDP by 33 to 35 per cent by 2030 from 2005 levels and reach about 40 per cent non-fossil power capacity.

India must mitigate through clean energy and adapt through resilient farming, disaster preparedness and protection of the Himalaya and the coast, where the damage arrives first.

On 26 December 2004 a great earthquake off Sumatra sent a tsunami across the Indian Ocean; India, with no warning system, lost more than ten thousand lives on its eastern coast and islands.

Why tsunamis occur

• Subduction earthquakes: most tsunamis follow shallow, high-magnitude quakes where one plate is thrust under another and the seabed is suddenly lifted, displacing the whole water column; the 2004 event occurred at the boundary of the Indian and Burma plates.
• Other triggers: submarine landslides, volcanic collapse (Krakatoa, 1883) and, rarely, meteorite impact.
• Amplification on arrival: waves slow and rise in shallow water; funnel-shaped bays, flat low coasts and the loss of mangroves and dunes let them run far inland.
• India's exposure: the Andaman-Sumatra arc in the east and the Makran zone in the Arabian Sea.

Effects on life and economy

• Life: deaths concentrated in Tamil Nadu, with Nagapattinam worst hit, the Andaman and Nicobar Islands, Andhra Pradesh, Kerala and Puducherry; fishing villages wiped out, families displaced for years, and women and children disproportionately among the dead.
• Economy: boats, nets and harbours destroyed, ending fishing incomes overnight; ports, roads, power lines and the Car Nicobar air base damaged; farmland and wells salinised; tourism collapsed and rebuilding absorbed public funds for years.

Preparedness under NDMA guidelines (2010)

• Early warning: the Indian Tsunami Early Warning Centre at INCOIS, Hyderabad, links seismic stations, bottom-pressure recorders and tide gauges to issue alerts within minutes; last-mile dissemination by siren, radio, SMS and local officials.
• Risk assessment and land use: inundation and vulnerability maps for every coastal district; coastal zoning, setback lines and tsunami-resistant building codes; elevated shelters and vertical evacuation in dense areas.
• Bio-shields: mangroves, casuarina belts and dune restoration along exposed coasts.
• Community readiness: awareness campaigns, school curricula, mock drills, marked evacuation routes and trained village response teams.
• Institutions: clear roles for NDMA, State and district authorities under the Disaster Management Act 2005, NDRF battalions on the coast, hospital preparedness and periodic review of plans.

India now has the warning system it lacked in 2004; what remains is to make coastal communities, buildings and land use as ready as the sensors.

Mob violence is the unlawful use of force by a crowd against a person or group, usually on rumour or suspicion, which substitutes the crowd's verdict for the courts and the police.

Causes

• Rumour on social media: WhatsApp messages about child-lifters led to several people being beaten to death in Jharkhand in May 2017; forwarding outruns any police response.
• Identity-based vigilantism: self-styled cow protectors killed Mohammad Akhlaq in Dadri (2015) and Pehlu Khan in Alwar (2017) and flogged Dalits in Una (2016); Junaid Khan was killed on a train near Ballabhgarh in June 2017.
• Impunity: slow trials, low conviction, police delay or complicity and political patronage teach crowds that violence carries no cost.
• Distrust of justice: crowds seek 'instant justice' against suspected thieves, rapists and witches, as when a rape accused was dragged from jail and lynched in Dimapur (2015).
• Crowd psychology: anonymity dissolves individual guilt, while prejudice, unemployment and frustration among young men supply the tinder.

Consequences

• Life and liberty: killings and injuries, fear among minorities and Dalits, families uprooted; Article 21 rendered hollow for the victims.
• Rule of law: the State's monopoly over force erodes, the police lose credibility, and each unpunished case invites the next.
• Social fabric: communal polarisation, cycles of retaliation and distrust between communities.
• Economy: cattle trade, dairy, leather and transport disrupted; investors and tourists read lynchings as State failure.
• Politics and image: governance discredited at home and India's human-rights record questioned abroad.

Way forward

• Prompt FIRs and fast-track trials, personal accountability of station officers and district magistrates, rumour-busting with platforms and local media, community policing and victim compensation (since then, the Supreme Court in Tehseen Poonawalla (2018) laid down preventive, remedial and punitive measures and urged Parliament to consider a special law).

Mob violence recedes only when policing is swift and impartial, officials answer for inaction, and rumour and hatred are countered before they turn into crowds.

Terrorism strikes at the State's first duty, the safety of its citizens, and it lives on money, arms, ideology and safe havens; curbing it means cutting each of these lifelines.

Solutions

• Intelligence: strengthen the Multi-Agency Centre and NATGRID, integrate State intelligence, invest in human sources and technical surveillance, and share actionable inputs in real time.
• Policing and borders: modernise State police as first responders, fence and electronically watch borders, complete coastal security with marine police and the Coast Guard, and keep NSG hubs ready for rapid response.
• Law and courts: use the Unlawful Activities (Prevention) Act, fast-track terror trials, protect witnesses, and give the National Investigation Agency the reach to pursue cross-State cases.
• Financial choke: the Prevention of Money Laundering Act, the Financial Intelligence Unit and FATF standards to trace and freeze funds.
• Countering radicalisation: monitor online recruitment, engage community and religious leaders, run deradicalisation and rehabilitation programmes, and expand education and jobs in Jammu and Kashmir, the Northeast and left-wing extremism districts.
• Diplomacy: press for the Comprehensive Convention on International Terrorism at the UN, use FATF and UN sanctions listings against sponsors, and deepen intelligence pacts with partners.
• Rights and trust: due process, no collective punishment and accountable security forces, so that counter-terrorism does not create the next recruit.

Major sources of terrorist funding

• Hawala and other informal transfers that leave no banking trail.
• Fake Indian currency notes pushed in through neighbouring countries.
• Narcotics from the Golden Crescent and Golden Triangle, and smuggling of gold and arms.
• Extortion, ransom and 'levies' on contractors, mining and transport, especially by left-wing extremists in central India.
• State sponsorship by hostile agencies.
• Charities, NGOs and diaspora donations diverted from their stated purpose.
• Cyber fraud, front companies and, increasingly, virtual currencies.
• India's counters: the Terror Funding and Fake Currency cell of the NIA, FCRA scrutiny of foreign funding, demonetisation (2016) aimed partly at counterfeit notes, and the UAPA offence of raising funds for terrorism.

Terrorism yields to a combined response: sharp intelligence, dried-up finance, fair and fast justice and communities that trust the State, backed by cooperation across borders.
