 What Is Extreme Poverty?

  • Defined by the World Bank as living on less than $2.15/day (2017 PPP).
  • Core indicators: lack of food security, no access to sanitation, healthcare, electricity, education.
  • Used globally to measure SDG-1 implementation.

Relevance

GS 1 – Society

  • Global poverty trends, demographic transitions.
  • Regional disparities (Asia vs Africa).
  • Social indicators: education, health, inequality.

GS 2 – International Relations / Social Justice

  • SDG-1, SDG-10 performance.
  • Role of institutions (World Bank, IMF, UN).
  • Governance gaps in fragile states.

GS 3 – Economy

  • Growth–poverty elasticity.
  • Structural transformation, employment, productivity.
  • Climate vulnerability and conflict economics.
  • Global poverty projections and economic stagnation in Africa.

What Has Happened Since 1990? (Global Background)

  • 1990: 2.3 billion people in extreme poverty.
  • 2024: Decline by 1.5 billion, one of the largest improvements in human history.
  • Drivers:
    • Rapid Asian growth (China, Indonesia, India, Bangladesh).
    • Structural transformation (manufacturing, urbanisation).
    • Trade integration.

Why Rapid Decline Is Slowing Now

  • In the 1990s, most poor people lived in fast-growing Asian economies.
  • Today, most extremely poor live in stagnating African economies (Madagascar, DR Congo, Malawi, Mozambique, Burundi, CAR).
  • GDP per capita in these countries has not grown for decades.

Projections (World Bank + IMF)

A. Up to 2030

  • Extreme poor decline from 831 million (2025) to 793 million (2030).
  • Decline modest; nowhere close to earlier pace.

B. After 2030

  • Reversal begins: number starts rising due to:
    • Stagnant African economies
    • High fertility
    • Climate vulnerability
    • Weak state capacity

C. Geographic shift

  • 1990: Most poor in Asia.
  • 2024–2040: Majority in Sub-Saharan Africa.

Why Progress Is Stalling ?

  • Economic stagnation in core African states (per capita income same as 1950 in Madagascar).
  • Mean incomes below poverty line → redistribution alone cannot eliminate poverty.
  • Population growth outpacing economic growth.
  • Climate shocks and conflicts.
  • Weak human capital: low productivity, poor education, poor health.

How Latin American Countries Fit Into This Picture (Panama, Bolivia, Mexico, Brazil)

A. Mexico

  • Middle-income country with moderate poverty reduction.
  • Extreme poverty dropped significantly 1990–2015; stagnated thereafter.
  • Drivers:
    • Manufacturing-based growth (NAFTA)
    • Social transfer programmes (Oportunidades)
  • Challenges:
    • Regional disparity (South vs North)
    • Crime, informality
    • Slow post-2015 GDP growth

B. Brazil

  • Major decline in extreme poverty 2003–2014 (Bolsa Família, commodity boom).
  • Recent stagnation due to:
    • Political instability
    • Low productivity
    • Commodity cycle downturn
  • Still far ahead of Africa; baseline poverty much lower.

C. Panama

  • One of Latin America’s fastest-growing economies; extreme poverty declined sharply (Canal services, logistics).
  • Challenges:
    • High inequality
    • Indigenous-region poverty pockets remain.

D. Bolivia

  • Poverty reduction since 2005 due to:
    • Hydrocarbon boom
    • Cash transfer schemes
  • But growth slowdown post-2014 → stagnation.
  • Still better trajectory than African stagnators but not Asian-style high growth.

Overall Latin America Trend

  • No stagnation as deep as Africa, but insufficient growth to replicate Asian-style poverty elimination.
  • Inequality a persistent drag across region.

Chart Logic Explained (Charts 1A–1D & Chart 2)

Charts 1A & 1B (High-growth Asian countries)

  • China, Indonesia, India, Bangladesh → large initial poverty shares (>60%)
  • Rapid GDP/capita rise → large decline (<10%).

Charts 1C (Latin America e.g., Mexico, Brazil, Bolivia, Panama)

  • Lower initial extreme poverty.
  • Reduction is slower because:
    • Growth moderate, not explosive.
    • Inequality high.
    • Poverty is more structural, less mass-extreme.

Charts 1D (African stagnators)

  • DR Congo, Malawi, Burundi, CAR, Mozambique
  • GDP/capita stagnant for decades.
  • Extreme poverty remains >50%.

Chart 2 (Projections to 2040)

  • Shows a break from past trend:
    • Decline until 2030
    • Rise afterward
  • Latin America stays low-extreme-poverty but not driving global reduction.
  • Asia essentially exits extreme poverty.
  • Africa drives global numbers upward.

Key Insight: Redistribution vs Growth

  • Countries like Madagascar, DR Congo:
    • Mean income < poverty line
    • Even perfect redistribution keeps everyone poor
  • Only sustained GDP growth can eliminate extreme poverty.

Why Future Looks Different From Past

  • Earlier gains came from countries that were poor but grew rapidly.
  • Now most extremely poor live in countries with:
    • Very low state capacity
    • Fragile institutions
    • Climate vulnerability
    • Conflict
    • Weak human capital
  • Without structural transformation, the poverty trap deepens.

Implications for SDGs

  • SDG-1 (End Poverty by 2030) will not be met.
  • SDG-10 (Inequality) becoming more central.
  • Africa becomes global development priority.

Policy Lessons

  • Growth-first strategy essential in low-income countries.
  • Need strong investment in:
    • Education
    • Health
    • Agricultural productivity
    • Climate resilience
    • Governance reforms
  • Redistribution works only after basic growth begins.


Why Is This in News?

  • The Union Government introduced two new Bills in Parliament:
    • Health Security Cess Bill, 2025
    • Central Excise (Amendment) Bill, 2025
  • Objective: Replace the soon-ending GST Compensation Cess on tobacco with new revenue streams and bring pan masala manufacture under tighter fiscal regulation.
  • Context: GST compensation cess on tobacco to discontinue after repayment of COVID-era borrowings.

Relevance

GS 2 – Governance / Polity

  • Fiscal federalism: CentreState financial relations.
  • Legislative process (Bills introduced in Parliament).
  • Public health as a State subject; non-shareable cess debate.

GS 3 – Economy / Public Health

  • Pigouvian taxes.
  • Sin goods taxation and behavioural economics.
  • Revenue mobilisation post-GST cess sunset.
  • Illicit trade, compliance, machine-based excise monitoring.

Basics

  • GST Compensation Cess (2017present)
    • Levied on sin goods: tobacco, aerated drinks, coal, pan masala, etc.
    • Purpose: Compensate States for revenue loss due to GST rollout.
  • Compensation tenure: 5 years (2017–2022), extended to repay loans taken during COVID years due to shortfall.
  • Tobacco & pan masala: High-elasticity sin goods used for revenue + public health control.

Key Features of the New Bills

A. Health Security Cess Bill, 2025

  • Introduces a new cess on tobacco products.
  • Purpose:
    • Replace GST compensation cess as it sunsets.
    • Generate earmarked funds for health and national security.
  • Target of levy:
    • Machines installed or processes undertaken in pan masala and similar harmful product manufacturing.

B. Central Excise (Amendment) Bill, 2025

  • Enhances excise duty on tobacco products.
  • Reconfigures the tax framework to ensure:
    • Continuous revenue after GST compensation cess ends.
    • Stabilisation of the tax base for sin goods.

Rationale Behind the Move

Fiscal Rationale

  • GST compensation cess on tobacco is ending, but:
    • COVID-era borrowings still being repaid.
  • Tobacco is a high-yield, low-compliance-elasticity sector:
    • Ensures steady revenue.
  • Pan masala sector has high evasion risk:
    • Machine-based cess improves traceability and compliance.

Public Health Rationale

  • Tobacco-related deaths in India: ~1.3 million annually.
  • Pan masala very high in carcinogens (areca nut).
  • Higher taxes = reduced affordability, especially among youth.

Governance Rationale

  • Machine-based cess on pan masala aligns with:
    • FMCG excise surveillance model (packaging line tracking).
    • Anti-evasion efforts used earlier (pre-GST) under the Pan Masala Packing Machines Rules.

Economic & Policy Implications

For Centre–State Fiscal Dynamics

  • Signals the final drawdown of GST compensation.
  • States lose a predictable revenue stream; Centre creates a new central cess (non-shareable with States).

For Industry

  • Higher duties raise production costs for:
    • Cigarettes
    • Chewing tobacco
    • Pan masala
  • Likely impacts:
    • Increased MRP
    • Reduced consumption
    • Pushback from industry lobbies

For Public Health

  • WHO recommends a minimum 75% tax share in retail price of tobacco.
  • India’s effective burden still < 60% for many tobacco forms.
  • New cess + increased excise brings India closer to global health norms.

For GST Architecture

  • Marks a shift from compensation cess to purpose-specific cesses.
  • Raises debate on:
    • Fragmenting GST into multiple cesses.
    • Compliance burden on industries.
    • Fiscal federalism concerns.

 Political & Parliamentary Context

  • Bills introduced amid Opposition sloganeering on unrelated political issues.
  • Winter Session traditionally used for major tax reforms.
  • Lok Sabha simultaneously passed the Manipur GST Amendment Bill, reflecting a focussed GST reform push.

Challenges & Criticisms

  • States may resent loss of compensation-related certainty.
  • Health cess not shared with States despite health being a State subject.
  • Risk of increasing illegal/unregulated tobacco trade.
  • Pan masala manufacturers may shift to unregistered, small units to evade machine-based cess.

Value Addition (Data + Concepts)

  • India is second-largest tobacco consumer globally.
  • Economic cost of tobacco use: 1% of GDP (ICMR estimate).
  • Sin taxes follow Pigouvian taxation principles.


Why Is It in News?

  • Rising concern over pollution load from human waste, untreated sewage, industrial effluents, oil spills, and heavy metals.
  • Rivers such as Ganga and Yamuna continue to receive untreated discharges despite improvements.
  • Government and scientific bodies pushing bioremediation as a scalable, low-cost, sustainable alternative to traditional clean-up technologies.
  • India evaluating national standards, biosafety norms, and GM microbe regulation to support bioremediation expansion.
  • Growing interest as part of Swachh Bharat, Namami Gange, Clean Technology Programme, and global green technology trends.

GS 2 – Governance

  • Regulatory gaps: biosafety norms, GM microbe rules.
  • CentreState urban waste management responsibilities.

What Is Bioremediation?

  • Use of microorganisms (bacteria, fungi, algae), plants, or microbial enzymes to degrade, detoxify, or immobilise pollutants.
  • Converts toxic substances (oil, pesticides, plastics, heavy metals) into harmless by-products like CO₂, water, organic acids.
  • Works through microbial metabolism where pollutants become energy or nutrient sources.

Types of Bioremediation

  • In situ: Treatment at the contaminated site
    • Oil-eating bacteria sprayed on ocean spills
    • Bioventing, biosparging for soil
  • Ex situ: Contaminated material removed and treated elsewhere
    • Bioreactors, biopiles, land farming
  • Modern versions:
    • GM microbes designed to tackle plastics, hydrocarbons, persistent organic pollutants
    • Nanobioremediation combining nanomaterials with microbes

Why Does India Need Bioremediation?

  • Severe pollution burden
    • Ganga and Yamuna receive large volumes of untreated sewage
    • Industrial hotspots contaminated with heavy metals, hydrocarbons, solvents
  • Traditional methods costly
    • Physico-chemical methods generate secondary waste, require high energy
  • Bioremediation advantages
    • Cheaper, scalable, energy-efficient

 Why is it in News?

  • Union Cabinet approved a ₹7,280-crore scheme to establish integrated REPM manufacturing facilities in India.
  • Aim: Convert rare earth oxides metals alloys permanent magnets, reducing import dependence.
  • Announcement comes as China tightens export controls on rare earth elements (REEs) and magnets, disrupting global supply chains.

Relevance

GS 1 – Geography

  • Mineral distribution in India (monazite sands: TN, Kerala, Odisha).
  • Resource geography and strategic minerals.

GS 2 – International Relations

  • Strategic minerals in geopolitics (US–China tech war).
  • Global supply chain dependencies.
  • Critical minerals alliances with Japan, US, EU.

GS 3 – Science & Tech

  • Metallurgy, magnet technology, refining and separation tech.
  • REPM (NdFeB) magnet ecosystem.

What are Rare Earth Elements (REEs)?

  • Group of 17 elements: 15 lanthanides + Scandium + Yttrium.
  • Properties: High magnetic strength, heat resistance, conductivity.
  • Applications:
    • EV motors
    • Wind turbine generators
    • Electronics and semiconductors
    • Defence systems (missiles, radars, avionics)
    • Smartphones, hard drives
  • REEs are relatively abundant, but extraction is costly, energy-intensive, and polluting.

China’s Dominance: Extent and Strategy

  • 70% of global production, 90% of global processing, but only 30% of known reserves.
  • Controls entire value chain: mining processing magnet manufacturing.
  • Tools of dominance:
    • 2009: Export quotas → struck down by WTO in 2015.
    • 2020: Restricted graphite exports.
    • 2021: Export licensing to control downstream industries.
    • 2024-25: Export restrictions on 7 rare earths and finished magnets.
  • Impact on industries:
    • EV makers worst affected, followed by electronics & defence.
    • Part of broader US–China trade and tech war.

Why India is Prioritising REEs?

  • REEs are critical for:
    • Electric mobility (EV motors = NdFeB magnets)
    • Renewables (wind turbines)
    • Electronics manufacturing
    • Defence and space systems
  • India’s situation:
    • Imports 53,000+ MT of REE magnets (FY 2024-25).
    • Holds ~8% of global REE reserves, mainly monazite sands (TN, Kerala, Odisha, Andhra).
    • Produces less than 1% of global REEs.

Government Moves Toward Self-Reliance

New ₹7,280-crore REPM scheme

  • Supports end-to-end magnet manufacturing.
  • Aim: Create India’s first complete rare-earth magnet supply chain.

National Critical Mineral Mission (2024–2031)

  • Total outlay: 34,300 crore (₹16,300 crore approved Jan 2024).
  • Focus areas:
    • Exploration
    • Processing
    • Refining
    • Recycling (end-of-life electronics)

Mining reforms

  • Private sector allowed entry since August 2023.
  • Auctions of REE-rich blocks in progress.

Structural Challenges for India

  • Refining and separation infrastructure absent (core of China’s strength).
  • Skill gaps in metallurgy, material sciences, precision magnet making.
  • Regulatory hurdles: environmental approvals, slow exploration licensing.
  • Long gestation period: 5–8 years for full supply chain maturation.

Opportunities India Can Leverage

  • Large monazite deposits rich in Neodymium (Nd) → essential for permanent magnets.
  • Growing ecosystem of magnet recycling from e-waste.
  • Global diversification push away from China → aligns with India’s manufacturing ambitions.
  • Strategic potential:
    • Reduce dependence in EVs, defence, electronics.
    • Build partnerships with Japan, US, EU (who are all seeking non-China REE suppliers).

Strategic Significance

  • Economic dimension
    • Reduces import bill for magnets & REEs.
    • Boosts Make in India for EVs, electronics, renewables.
    • High-value segment: REPMs (NdFeB magnets) are 10x more valuable than raw REE oxides.
  • Geopolitical dimension
    • Counters China’s resource weaponisation tactics.
    • Strengthens India’s role in global critical minerals alliances (Indo-Pacific partnerships).
  • Security dimension
    • Defence systems—from missile guidance to electronic warfare—depend on REPMs.
    • Reducing vulnerability enhances strategic autonomy.
  • Environmental dimension
    • Domestic production necessitates safe mining + environmentally sound refining.
    • Recycling can reduce pollution and import dependence simultaneously.

Conclusion

  • REEs are indispensable for modern technology; China dominates supply chains.
  • India has reserves but lacks extraction–processing–magnet manufacturing capacities.
  • The ₹7,280-cr scheme + National Critical Minerals Mission aim to build self-reliance.
  • Success depends on deregulation, infrastructure, skilled workforce, and global collaboration.


Why is it in News?

  • Department of Telecommunications (DoT) has ordered all smartphone manufacturers to pre-install the Sanchar Saathi app on devices sold from March 2026.
  • Manufacturers must ensure the app cannot be disabled or restricted.
  • Move follows rising concerns about IMEI tampering, SIM misuse, cross-border digital frauds, and second-hand phone black markets.

Relevance

GS 2 – Governance

  • Regulatory power of DoT.
  • Device-level regulation, digital governance.
  • Privacy vs security debate.
  • Mandatory pre-installation and consumer rights.

GS 3 – Internal Security / Cybersecurity

  • IMEI tampering, SIM fraud, digital impersonation scams.
  • CEIR integration for stolen device tracking.
  • Telecom security architecture strengthening.

What is Sanchar Saathi?

  • Launched in 2023 as a portal; later developed into a mobile app.
  • Provides services via CEIR (Central Equipment Identity Register).
  • Core functions:
    • Check mobile connections issued in your name.
    • Report scam calls, financial fraud attempts.
    • Identify and report IMEI tampering.
    • Block, track, and remotely disable stolen/lost devices.
    • Prevent re-activation of stolen phones using new SIMs.

What Has the Government Ordered Now?

  • Mandatory pre-installation of Sanchar Saathi on all phones sold after March 2026.
  • Manufacturers must ensure no disabling, no removal, and no restriction of functions.
  • Objective:
    • Verify authenticity of IMEIs.
    • Prevent second-hand market fraud, resale of stolen/blacklisted phones.
    • Curb scam calls, cross-border digital fraud operations.

Why This Mandate? Rising Telecom Security Threats

IMEI tampering

  • Single IMEI used simultaneously on multiple devices.
  • Makes legal action, tracing, and blacklisting difficult.

Cross-border digital fraud

  • Fraudsters use Indian numbers abroad even after the original SIM is removed.
  • Enables government impersonation scams, “digital arrest” frauds, UPI extortion attempts.

Second-hand smartphone black market

  • India has one of the world’s biggest used-phone markets.
  • Stolen/blacklisted phones resold → buyers unknowingly become legal abettors.

Cybercrime explosion

  • Over 2.48 lakh complaints on Sanchar Saathi.
  • Over 2.9 crore requests to check mobile connections linked to users.
  • In October alone, 50,000 lost/stolen devices recovered via the app.

Technical Layer: IMEI Authentication Push

  • Device IMEI must match the one registered on the telecom network.
  • Sanchar Saathi + CEIR enables:
    • Real-time detection of tampered/spoofed IMEI.
    • Auto-blocking of cloned devices.
    • Permanent blacklisting of stolen phones.

What About Privacy Concerns?

  • DoT claims:
    • The app collects no user data (as per Google Play declaration).
    • Only helps verify IMEI and SIM-linkage.
  • However:
    • Pre-installation without option to disable → risk of perceived surveillance.
    • Unclear whether the app will auto-access IMEI or require manual input.
    • Past concerns:
      • Apple earlier resisted mandatory pre-installed TRAI DND app due to permissions (access to SMS/call logs).

Industry Reaction & Global Context

  • Smartphone makers typically resist government-mandated apps.
  • Apple has protested similar mandates in India before.
  • Internationally, tech firms resist “bloatware” and privacy-sensitive pre-loads.
  • The 2026 mandate may cause:
    • Industrial pushback
    • Negotiations on permissions
    • Possible technical challenges for foreign OEMs

Governance & Regulatory Perspective

DoTs rationale

  • SIM-binding + IMEI-verification essential to:
    • Eliminate anonymous numbers.
    • Reduce cross-border scam ecosystems.
    • Improve national telecom security architecture.

Target outcome

  • Unified system connecting device (IMEI), SIM, user identity, and operator’s network.
  • A core element of India’s cyber-fraud prevention strategy.

Benefits Expected

  • Reduced resale of stolen phones.
  • Faster recovery of lost devices.
  • Curbing large-scale OTP, UPI, and impersonation scams.
  • Greater transparency in second-hand sales.
  • Strengthened digital public infrastructure security.

Challenges Ahead

  • Manufacturer resistance (Android & iOS).
  • Potential privacy debates.
  • Usability issues if app requires repeated verification.
  • Risk of government overreach perception.
  • Ensuring app does not become a surveillance pipeline.

Overall Significance 

  • Strengthens India’s telecom cybersecurity ecosystem.
  • Part of the trend toward device-level and SIM-level regulation.
  • Linked to larger frameworks:
    • CEIR
    • Digital India
    • National Cyber Security Strategy (pending)
  • Shows government’s increasing focus on fraud prevention and digital trust


Why is is in News?

  • Multiple instances of GPS spoofing and GNSS (Global Navigation Satellite System) interference have been reported near major Indian airports.
  • Delhi airport saw repeated spoofing incidents, with similar reports from Kolkata, Amritsar, Mumbai, Hyderabad, Bengaluru, Chennai.
  • Ministry of Civil Aviation informed Parliament that the Wireless Monitoring Organisation (WMO) has been directed to identify the source of interference/spoofing.
  • These incidents pose a serious aviation safety risk, prompting DGCA and AAI to mandate reporting of any such events.

Relevance

GS 1 – Geography

  • GNSS systems (GPS, GLONASS, Galileo, BeiDou).
  • Satellite signal vulnerabilities in dense airspace.

GS 2 – Governance / IR

  • Civil aviation regulation by DGCA, AAI.
  • Cross-border interference and geopolitical angle.

GS 3 – Internal Security / Cybersecurity

  • Electronic warfare, jamming, spoofing.
  • Aviation cyber risks and national security.
  • Protection of critical infrastructure.

What is GPS Spoofing?

  • GPS spoofing = broadcasting fake GPS signals stronger than the real satellite signals.
  • Aircraft navigation systems may lock onto counterfeit coordinates, causing incorrect:
    • Position
    • Altitude
    • Speed
    • Flight path
  • Creates dangerous navigation deviations, especially during approach and landing.

What is GNSS Interference?

  • GNSS = GPS + other satellite systems (GLONASS, Galileo, BeiDou).
  • Interference includes:
    • Jamming: blocking signal reception.
    • Spoofing: altering positional data.
  • Both severely impact aviation safety, particularly in low-visibility or conflict zones.

What’s Happening in India?

  • Delhi airport reported multiple GPS spoofing events, especially near Runway 10.
  • Fake signals appear during approach and landing, when precision is critical.
  • Other airports (Kolkata, Mumbai, Bengaluru, Hyderabad, Chennai, Amritsar) also reported similar patterns.
  • November saw unusually high number of events around IGI Airport.

Why is This Dangerous?

Direct risks

  • Incorrect aircraft position → flight deviations.
  • Confusion between runways/flight paths.
  • Possible near-miss or runway excursions.
  • Overreliance on GNSS makes aircraft vulnerable.

Indirect risks

  • Increased pilot workload.
  • Potential exploitation by cyber actors during geopolitical tensions.
  • Compromised ATC situational awareness.

Government & Regulatory Response

DGCA

  • Made reporting of spoofing mandatory since 2023.
  • Working with AAI to enhance detection networks.

AAI

  • Monitoring interference near Delhi and other airports.
  • Engaging with WMO to trace source.

DoT/WMO

  • Mobilised resources to locate approximate spoofing location.
  • Investigating signal strength, direction, timestamps.

Airlines & Pilots

  • Instructed to report incidents immediately.
  • Asked to maintain heightened situational vigilance.

Possible Sources of Spoofing (Experts’ View)

  • Rogue personal or commercial jammers.
  • Cross-border interference drift.
  • Criminal networks using spoofers for evasion.
  • Malicious cyber actors (ransomware/malware targeting aviation infrastructure).
  • Faulty or misconfigured commercial GNSS repeaters.

No official source has been identified yet.

Global Context

  • GPS spoofing has risen worldwide:
    • Middle East conflict zones
    • RussiaUkraine war
    • China and South-East Asia maritime regions
  • Civil aviation globally is increasingly vulnerable.
  • ICAO has warned of “GNSS-denied environments” becoming common in geopolitically sensitive areas.

Why India is More Vulnerable ?

  • High-density aviation routes.
  • Heavily GNSS-dependent landing procedures (RNP/GLS).
  • Growing electronic warfare capabilities in neighbourhood.
  • Widespread availability of cheap spoofers online.

Technical & Security Measures Needed

  • Deploy GNSS interference monitoring stations around airports.
  • Integrate RAIM, SBAS, and inertial navigation fallback systems.
  • Combine radar + ADS-B + multilateration for redundancy.
  • Strict DoT controls on illegal RF devices.
  • Cybersecurity upgrades across airports and ATC.


Why is it in News?

  • The Union Cabinet has approved a ₹7,280-crore scheme to promote domestic manufacturing of Rare Earth Permanent Magnets (REPMs).
  • The scheme aims to set up integrated facilities that convert rare earth oxides metals alloys finished magnets, reducing India’s overwhelming dependence on Chinese imports.
  • This comes amid Chinas continued control over global REE supply chains, periodic export restrictions, and rising global demand from EVs, wind energy, electronics, robotics, defence.

  • India imports nearly all REPMs, especially from China, despite having 8% of global REE reserves.
  • In 2024–25 India imported ~53,000 tonnes of REPMs, over 90% from China.
  • Domestic REE output is <1% of global production.

Rising Domestic Demand

  • Demand projected to rise sharply due to:
    • Renewable energy expansion
    • EV ecosystem growth
    • Defence manufacturing
    • Electronics PLI schemes
  • Expected consumption to double by 2030.

Strategic Vulnerability

  • China controls:
    • 70% of REE production
    • 90% of global processing and magnet manufacturing
  • Has repeatedly restricted exports (2009, 2020, 2023, 2024), hurting global supply chains.

What Does the New ₹7,280-crore REPM Scheme Do?

Key Features

  • Supports 6,000 MT annual REPM production capacity (MT/PA).
  • Five beneficiaries to be chosen through competitive bidding.
  • Will offer:
    • Capex support up to 6,450 crore
    • 75% subsidy for setting up integrated REPM facilities
  • Focus on integrated operations, i.e., processing from oxides → metals → alloys → magnets within India.

Outcome Sought

  • Reduce Chinese import dependence.
  • Build domestic supply chains for EVs, defence, renewable energy.
  • Upgrade India’s metallurgical and materials-science ecosystem.

India’s Current Position

Strengths

  • Strong monazite reserves (Andhra Pradesh, Odisha, Tamil Nadu, Kerala).
  • Indian Rare Earths Ltd (IREL) produces some oxides (Nd, Pr, Dy).
  • Growing private sector interest in magnet recycling.

Weaknesses

  • No large-scale REPM manufacturing capacity.
  • Refining, metallisation and alloying infrastructure is minimal.
  • High entry-barriers:
    • Cost of plant
    • Technical know-how
    • Skilled manpower
    • Tight global intellectual property ecosystem
  • China’s aggressive pricing makes competition very difficult.

The China Factor

How China Built Dominance

  • State-supported mining, refining, and manufacturing.
  • Integrated supply chains linking mining → oxides → metals → alloys → magnets.
  • Low-cost production + subsidies.
  • Heavy rare-earth technologies tightly controlled.

Chinas Leverage

  • REEs used as a geopolitical tool—export controls imposed during trade tensions with:
    • U.S.
    • Japan
    • Taiwan
    • Europe
  • Magnets are central to China’s grip on EVs, electronics, and defence manufacturing.

How India Plans to Bridge the Gap ?

Domestic Initiatives

  • National Critical Mineral Mission (2024).
  • Funding for exploration and mineral mapping.
  • Mining block auctions (lithium, REEs).
  • Magnet recycling initiatives (urban mining).
  • Collaboration with Japan, Australia, U.S. on critical minerals.

Required Steps for Self-Reliance

  • Build refining and metallisation capacity.
  • Incentivise private players and joint ventures.
  • Increase IREL capacity + technology partnerships.
  • Create a full supply chain reducing foreign dependence.

 Challenges Ahead

  • High cost vs China’s subsidised pricing.
  • Environmental concerns in mining/refining.
  • Technological complexity in magnet production.
  • Long gestation periods for mines (7–10 years).
  • Need for advanced materials-science R&D and IP development.


Why is it in News?

  • A new analysis by Climate Trends (2025) covering 15 major Indian cities (2015–2025) finds:
    • No city recorded safe air quality (AQI < 50).
    • Delhi remains the most polluted city across 10 years.
    • Pollution shows a regional pattern: north India worst, south-west relatively better.
    • Persistent high PM levels in north; annual best AQI in Chennai & Mumbai.

What is AQI & Why It Matters?

  • Air Quality Index (AQI) categorises air quality from 0–500:
    • 0–50: Good
    • 51–100: Satisfactory
    • 101–200: Moderate
    • 201–300: Poor
    • 301–400: Very Poor
    • 401–500: Severe
  • The study uses annual mean AQI—a more reliable long-term pollution indicator than daily spikes.

Overall Air Quality Performance

  • Delhis annual mean AQI:
    • Highest in 2016 (over 250)
    • Slight improvement after 2019
    • Still remains in poorvery poor category
  • In 2025 (so far):
    • Delhi AQI ~180–190
    • Lucknow, Varanasi, Ahmedabad, Pune: also experienced prolonged poor AQ levels

North Indian Cities Perform the Worst

  • Six cities—Delhi, Lucknow, Varanasi, Kanpur, Noida, Ghaziabad—consistently show high PM2.5 & AQI deterioration, especially winter.
  • Annual best AQI never enters “good” or even “satisfactory” range.

South & West Indian Cities Perform Better

  • Chennai, Bengaluru, Mumbai, Visakhapatnam show:
    • Better mean AQI levels (120–140 range)
    • More stable improvement post-2019
  • But they still fall short of clean air standards.

City-Level Variations

  • Chennai & Mumbai: best annual quality among all 15 cities
  • Bengaluru: did not record safe annual AQI even once but still far cleaner than north
  • Chandigarh, Visakhapatnam, Mumbai saw AQI improvements from 800 → 140 days of good-moderate air.

Why North Is More Polluted: Geographic & Climatic Factors 

1. Indo-Gangetic Plain Topography

  • North India is landlocked, unlike coastal south/west.
  • Bordered by the Himalayas in the north, preventing dispersion of pollutants.
  • Creates a “pollution bowl” where PM2.5 gets trapped.

2. Winter Inversion + Cold, Dry Air

  • Winter causes thermal (temperature) inversion:
    • The layer of warm air sits above cold air near the surface
    • Acts as a lid, trapping pollutants
  • Result: Smog, stagnation, prolonged pollution episodes.

3. Dust Load + Biomass Burning

  • Indo-Gangetic belt has heavy soil dust, crop residue burning, brick kilns, industrial clusters.

4. Weak Wind Speeds

  • North experiences slow winds in winter; lack of sea breezes.
  • This reduces pollutant flushing.

Why South & West Perform Better ?

  • Coastal cities (Chennai, Mumbai):
    • Sea breeze circulation disperses pollutants
    • Higher humidity and cleaner marine air reduce dust
  • Less temperature inversion
  • Fewer winter smog events
  • Lesser biomass burning and lower dust aerosol load

Structural Factors Adding to North’s Problem

  • Dense urban structure → surface roughness that slows wind dispersion
  • High vehicle density
  • More industrial clusters
  • High secondary aerosol formation in winter
