Terrorism and Challenges Related To It

International Convention for the Suppression of the Financing of Terrorism (CFT)

Why in the News?

Iran has officially ratified the UN International Convention for the Suppression of the Financing of Terrorism (CFT), signalling a major policy shift toward international financial reintegration.

Why such move by Iran?

  • Economic Isolation: Iran’s blacklisting by FATF in 2020 and U.S.-led sanctions have severely restricted its banking access, trade, and foreign investment.
  • Reformist Agenda: President Pezeshkian’s government seeks economic stabilization through engagement, not confrontation, with Western institutions.
  • Trade Barriers: Even traditional allies like Russia and China face difficulty trading with Iran due to its non-compliance with FATF norms.
  • Diplomatic Leverage: CFT accession signals willingness to reform and could help Tehran negotiate sanction relief or trade facilitation.
  • Political Balance: The government faces domestic opposition from hardliners who fear the law will expose Iran’s support for groups like Hezbollah and Hamas, but reformists view it as essential for economic recovery.

About the International Convention for the Suppression of the Financing of Terrorism (CFT):

  • Adopted: 1999 by the UN General Assembly; entered into force in 2002.
  • Parties: Ratified by 188 countries including India, making it one of the most widely accepted anti-terror treaties.
  • Objective: To criminalize, prevent, and punish the financing of terrorism and enhance international cooperation against terror-linked financial networks.
  • Definition: Financing terrorism includes collecting or providing funds—directly or indirectly—with intent or knowledge that they will be used for terrorist acts causing death or injury to civilians or non-combatants.
  • Key Provisions:
    • States must criminalize terror financing in domestic law.
    • Freeze, seize, and confiscate assets linked to terrorism.
    • Ban misuse of banking secrecy to block investigations.
    • Facilitate extradition, legal cooperation, and mutual assistance.
    • Ensure political or ideological motives cannot justify terrorist financing.
  • Legal Mechanism: Creates obligations for states to report suspicious transactions and cooperate across jurisdictions for enforcement.

FATF and CFT: Complementary Global Frameworks

  • CFT (1999): Provides the legal foundation, obligating states to define and criminalize terror financing under international law.
  • FATF (1989): Provides the operational and policy framework, setting 40 detailed recommendations for implementation, monitoring, and compliance.
  • Interaction:
    • FATF requires its members to implement CFT obligations in national systems.
    • CFT establishes criminalization and cooperation, while FATF ensures compliance, enforcement, and evaluation.
  • Iran’s Case:
    • FATF blacklisted Iran for failure to adopt CFT and AML standards.
    • Ratification of CFT is Iran’s first step toward FATF re-evaluation and possible removal from the blacklist.
    • Compliance would enable Iranian banks to restore correspondent relations and resume limited international transactions.

Air Pollution

[22nd October 2025 ] The Hindu Op-ed: Unreliable air and noise data, real-time deception

PYQ Relevance

[UPSC 2023] Describe the key points of the revised Global Air Quality Guidelines (AQGs) recently released by the WHO. How are these different from its last update in 2005? What changes in India’s National Clean Air Programme are required to achieve these revised standards?

Linkage: This PYQ directly links to the article’s focus on unreliable air quality data and weak monitoring under NCAP. Since pollution is a recurring UPSC theme, it highlights how aligning India’s policies with updated WHO standards demands scientific integrity and credible data.

Mentor’s Comment

When truth itself is blurred by flawed data, governance becomes an illusion. India’s air and noise monitoring systems, meant to be the foundation of environmental policy, are now under scrutiny for misleading the nation with inaccurate data. This is not just a story about malfunctioning sensors but about the collapse of scientific integrity, accountability, and public trust. The issue is no longer technical; it is constitutional, affecting citizens’ Right to Health and Life.

Why in the News

Two major failures in India’s environmental monitoring systems, Delhi’s Real-Time Air Pollution Network and Lucknow’s National Ambient Noise Monitoring Network, have exposed disturbing lapses in data integrity and governance. For the first time, even raw government data is being accused of misleading the public by understating pollution levels. Sensors placed in less polluted areas, faulty installations under tree cover, and outdated noise regulations have collectively raised alarm. This is significant because policy credibility, public health, and India’s global environmental reputation now stand compromised.

Introduction

Environmental governance in India has entered a critical phase. Despite massive investments and advanced technology, monitoring systems for air and noise pollution have failed to inspire confidence. When environmental data is unreliable, policies derived from it lose direction. As Delhi continues to suffocate under toxic smog and Lucknow’s soundscape exceeds permissible decibel levels, the larger question emerges — can real-time governance be meaningful when real-time data is deceptive?

Policy Built on Sand: When Data Loses Credibility

  1. Flawed Sensors: Multiple audits, including the Comptroller and Auditor General (CAG) report, reveal that several air-quality sensors in Delhi are placed behind walls or under tree cover, leading to inaccurate readings.
  2. Misleading Reports: Delhi’s official Air Quality Index (AQI) often shows “moderate” levels even as citizens gasp through toxic smog, undermining public trust.
  3. Governance Crisis: When data itself is unreliable, policy decisions on stubble burning, vehicular restrictions, and industrial emissions lose legitimacy.
  4. International Impact: Weak monitoring erodes India’s credibility under the Paris Agreement and WHO Air Quality Standards.

Sound of Silence: Noise Monitoring Failure in Lucknow

  1. Defective Network: Lucknow’s National Ambient Noise Monitoring Network fails to record accurate decibel levels; sensors are either malfunctioning or poorly calibrated.
  2. Outdated Regulation: India continues to rely on the Noise Pollution (Regulation and Control) Rules, 2000, which are inadequate and below WHO standards.
  3. Weak Enforcement: Penalties are minor, compliance is poor, and urban noise remains unregulated, especially around airports and religious places.
  4. Constitutional Concern: The Supreme Court recently transferred pleas on noise around Delhi Airport to the NGT, acknowledging that noise is a public health and fundamental rights issue under Articles 19 and 21.

Science or Spectacle: Technology Without Transparency

  1. Spectacle over Substance: Governments deploy shiny monitoring hardware but ignore scientific calibration and audits.
  2. Opacity in Data: Citizens are misled when real-time pollution data is selectively downplayed to show moderate levels.
  3. Public Deception: Misleading indices delay judicial intervention and suppress citizen voices demanding clean air.
  4. Democratic Erosion: Governance becomes a contest between citizens and industries, with flawed numbers protecting inaction.

The Human Cost: Health and Life Expectancy

  1. Health Impact: Exposure to NO₂ and PM2.5 not only weakens lungs but also accelerates myopia and aggravates asthma in children.
  2. Data from Reports: The Air Quality Life Index (Energy Policy Institute) shows that if Delhi met WHO air standards, life expectancy would rise by 8.2 years.
  3. National Toll: Across India, air pollution cuts life expectancy by nearly 5 years, making this a silent epidemic.
  4. Flawed Data = Lost Lives: When monitoring fails, policies fail, and citizens continue to breathe poison unknowingly.

Restoring Credibility: Science as the Foundation

  1. Independent Oversight: India lacks an independent audit panel for environmental monitoring, unlike global norms.
  2. Enforcement Gaps: Though CPCB has clear guidelines on sensor location and calibration, implementation remains lax.
  3. Need for Citizen Oversight: Making raw data publicly accessible and encouraging third-party audits will restore trust.
  4. Beyond Bureaucracy: Environmental monitoring should be treated not as a formality, but as a scientific and ethical duty.

Conclusion

India’s real-time air and noise monitoring crisis is a wake-up call. The credibility of environmental governance rests not on political optics but on scientific truth. Without transparent data and independent audits, policies lose legitimacy and citizens lose trust. The real cost is borne not in GDP but in children’s lungs and sleepless nights. Science, integrity, and public accountability must anchor India’s environmental data revolution, else we risk turning real-time monitoring into real-time deception.

Rural Distress, Farmer Suicides, Drought Measures

Can rural education stop youth migration?

Why in the News

India stands at a demographic crossroads. According to the Periodic Labour Force Survey (PLFS) 2020–21, nearly 29% of India’s population are migrants, with 89% hailing from rural areas. Over half of these migrants are aged 15–25, indicating that the nation’s most productive youth are leaving villages in search of livelihood. This is a turning point in India’s development trajectory, education, once seen as a ladder out of poverty, has lost its power to insulate youth from migration pressures. The mismatch between education and employment, coupled with the pandemic-driven reverse migration, has sparked urgent questions: Can India reimagine rural education and economies to retain its young talent?

Introduction

Migration has long shaped India’s economic and social fabric. But what was once seen as a path to progress is now exposing deep cracks in India’s development model. The migration of rural youth to urban centres reflects unmet aspirations, inadequate rural opportunities, and disillusionment with the promise of education.

The Covid-19 pandemic acted as a brutal reminder, as nearly 40 million workers were forced to return home during the first lockdown. It exposed the vulnerability of India’s informal urban workforce and, simultaneously, revealed the untapped potential of rural revitalization.

Rethinking the Roots of Migration

  1. Structural Imbalance: Migration is not purely about aspiration; it arises from rural distress and uneven regional development.
  2. Labour Force Data: PLFS data shows rural India continues to be the main supplier of labour, not a site of dignified livelihood.
  3. Educational Mismatch: Graduates are increasingly unemployed, revealing a disconnect between degrees and employable skills.

Why is Education Failing to Prevent Migration?

  1. Broken Linkage: Education no longer guarantees employment. Youth with degrees often find no dignified jobs in their hometowns.
  2. Graduate Unemployment: India’s expansion of higher education hasn’t translated into job creation, instead, it has produced educated unemployment.
  3. Informal Urban Absorption: About 49% of youth migrants work as daily wage labourers and 39% as industrial workers, mostly on temporary contracts.
  4. Gender Disparity: While 86.8% of women migrate for marriage, most men migrate for work, reflecting limited female labour participation despite mobility.

Pandemic: A Mirror to Rural Vulnerabilities

  1. Mass Exodus: Nearly 40 million workers returned home in 2020 (RBI, 2020), exposing the fragility of India’s urban informal economy.
  2. Urban Fragility: Cities like Delhi, Mumbai, and Bengaluru struggle with slums, pollution, waste, and overcrowding.
  3. Gendered Impact: Young women were more likely to lose jobs and slower to regain them (ILO, 2021), deepening gender inequality.

Reverse Migration: Stories of Hope and Resilience

  1. Agricultural Revival: Agriculture showed unexpected resilience, with a 39% increase in sown area in 2020 as returning workers revived farmlands.
  2. Success Stories:
    • Balaram Mahadev Bandagale (Raigad, Maharashtra) diversified into mango orchards using irrigation schemes, now earning higher income.
    • Chandrakant Pawar, once a migrant worker, returned to dairy farming and became Sarpanch, a symbol of empowered reverse migration.
  3. These examples highlight the potential of self-reliant rural ecosystems driven by local enterprise and education.

How Can Rural India Retain Its Youth?

  1. Diversified Rural Employment: Beyond agriculture, India needs to expand into dairy, poultry, food processing, handicrafts, rural logistics, renewable energy, and tourism.
  2. Rural Entrepreneurship: Government schemes like Pradhan Mantri Mudra Yojana, Start-Up India, and FPO expansion can empower youth — but need integration and youth-focused redesign.
  3. Digital & Renewable Energy Jobs:
    • Solar panel maintenance, microgrid operations, and biofuel units can create decentralized jobs.
    • Digital infrastructure is essential to bridge divides and enable e-commerce, telemedicine, and remote work.
  4. Agri & Eco-Tourism: Leveraging local ecology and culture can create sustainable livelihoods rooted in community pride.

Changing the Narrative: Migration as a Choice, Not Compulsion

  1. Breaking Stigma: Returning to villages must not be equated with failure. Reverse migrants should be portrayed as innovators, not dropouts.
  2. Portable Social Protection: Schemes for health, education, and pensions should be location-independent, following the worker wherever they go.
  3. Balanced Urban–Rural Growth: Development must prioritize equitable access to education, digital infrastructure, and markets in rural India.

Conclusion

India’s youth migration crisis is not merely about movement, it’s about meaning. It questions what development truly offers and whether education still promises empowerment. The path forward lies in integrating rural education with employable skills, expanding decentralized job ecosystems, and redefining success beyond cities. If India invests in its rural potential, migration will no longer be a story of escape, it will become a story of choice, dignity, and empowerment.

PYQ Relevance

[UPSC 2024] Why do large cities tend to attract more migrants than smaller towns? Discuss in the light of conditions in developing countries.

Linkage: This PYQ directly links with the article’s theme by highlighting how rural distress, weak educational–employment linkages, and uneven regional development push youth towards cities. It reflects the same structural imbalance where urban centres appear as opportunity hubs while villages remain economically stagnant.

Foreign Policy Watch: India-Afghanistan

Turning Tides: Pakistan-Afghanistan Tensions

Introduction

When the Taliban recaptured Kabul in August 2021, Pakistan perceived it as a strategic victory after two decades of covert support to the insurgents. However, the celebration was short-lived. Four years later, Pakistan faces an unprecedented internal security crisis, with over 2,400 people killed in militancy-related violence in 2025 alone. The rise of the Tehrik-e-Taliban Pakistan (TTP) and recent Pakistani airstrikes on Kabul (October 2025) signal a dangerous escalation — and a stark reversal of the country’s long-standing policy of using non-state actors as strategic assets.

Why in the News?

For the first time, Pakistan bombed Kabul, directly targeting militants across the Afghan border. This marks a major policy shift, as Islamabad traditionally treated the Taliban as an ally and buffer against India. The strikes came while Afghan Foreign Minister Amir Khan Muttaqi was visiting India, adding a symbolic twist to regional alignments. The scale of violence, with over 2,414 deaths this year, underscores the depth of Pakistan’s internal crisis and its failure to control militancy in Khyber Pakhtunkhwa. This development has drawn comparisons to India’s own doctrine of cross-border strikes, raising questions about whether Pakistan is now borrowing from a playbook it once condemned.

The Illusion of Strategic Depth

  1. Taliban Patronage: Pakistan’s military establishment nurtured the Afghan Taliban for decades, offering refuge and logistical support during their insurgency against the U.S.-backed Afghan government.
  2. Strategic Depth Doctrine: Islamabad’s rationale was to create a friendly regime in Kabul that could serve as a buffer against India and offer “strategic depth” in case of war.
  3. Backfiring Reality: Instead, the Taliban’s rise empowered the TTP, an ideologically aligned but operationally separate entity, turning Pakistan’s proxy into its nemesis.

How the Taliban’s Return Changed the Equation

  1. End of Patron-Client Relationship: Once in power, the Taliban sought state-to-state relations, not subservience to Pakistan’s military agenda.
  2. Durand Line Dispute: Kabul never recognized the Durand Line, reigniting border tensions that colonial history had left unresolved.
  3. TTP Empowerment: Inspired by the Afghan Taliban’s triumph, the TTP now demands enforcement of strict Islamic law and reversal of the merger of tribal areas with Khyber Pakhtunkhwa.
  4. Refugee Crisis: Pakistan’s decision to deport thousands of Afghan refugees further worsened ties, adding a humanitarian dimension to political hostility.

Pakistan’s New Doctrine: Borrowing from India?

  1. Airstrikes as Deterrence: By bombing Kabul, Pakistan appears to be testing a new counter-terrorism strategy, directly holding Afghanistan responsible for cross-border militant attacks.
  2. India Parallel: The move is reminiscent of India’s 2016 and 2019 strikes on Pakistani territory after terror attacks in Uri and Pulwama.
  3. Diplomatic Irony: The timing, coinciding with the Afghan FM’s India visit, highlights shifting regional equations where India engages diplomatically, and Pakistan responds militarily.

The Security Crisis within Pakistan

  1. Rising Violence: The Khyber Pakhtunkhwa province has become the epicenter of TTP-led insurgency.
  2. Contradictory Policy: Pakistan’s dual policy of fighting terrorism while nurturing militants targeting its neighbors has eroded domestic stability.
  3. Blowback Effect: Militancy now threatens Pakistan’s political order, economic recovery, and regional credibility.
  4. Qatar-Brokered Ceasefire: A fragile truce mediated by Qatar hints at the international community’s anxiety over a new South Asian flashpoint.

Why Pakistan’s Strategy is Self-Defeating

  1. Cycle of Violence: Airstrikes may offer short-term political gains but deepen long-term instability.
  2. Internal vs External Conflict: Pakistan’s greatest threat now emanates from within its borders, not across them.
  3. Loss of Moral Credibility: Its past of backing non-state actors undercuts its legitimacy when accusing others of the same.
  4. Strategic Isolation: Continued conflict risks alienating even traditional allies like China and Gulf states, who seek regional stability.

Conclusion

Pakistan’s experiment with militant patronage has collapsed under its own contradictions. The strategic depth doctrine that once defined its Afghan policy has morphed into a strategic liability. Peace in Pakistan cannot be achieved through bombs over Kabul, but through a coherent internal reform of its security, political, and ideological ecosystem. As the editorial aptly concludes, “Pakistan cannot ensure internal security by bombing Afghanistan.”

PYQ Relevance

[UPSC 2013] The proposed withdrawal of the International Security Assistance Force (ISAF) from Afghanistan in 2014 is fraught with major security implications for the countries of the region. Examine in light of the fact that India is faced with a plethora of challenges and needs to safeguard its own strategic interests.

Linkage: The 2013 PYQ and this 2025 editorial both explore the Afghan theatre as a pivot of regional security, then, in anticipation of instability; now, in its full manifestation. Both are invaluable for analysing India’s neighbourhood policy, counter-terror strategy, and regional diplomacy in the post-US Afghanistan order.

Poverty Eradication – Definition, Debates, etc.

What is Rangarajan Poverty Line?

Why in the News?

After the C. Rangarajan Committee (2014) set India’s last official poverty line, economists from the Reserve Bank of India (RBI) have now revisited and updated the estimates using new household consumption data from Household Consumption Expenditure Survey (HCES) 2022–23.

Evolution of Poverty Measurement in India:

  1. Planning Commission (1962): ₹20 (rural) and ₹25 (urban) per month; excluded health and education.
  2. Dandekar & Rath Committee (1971): Calorie-based standard (2250 kcal/day).
  3. Y. K. Alagh Committee (1979): Calorie-linked poverty line (2400 kcal rural; 2100 kcal urban).
  4. Lakdawala Committee (1993): Introduced state-specific and composite consumption baskets.
  5. Tendulkar Committee (2009): Uniform basket for rural/urban; ₹816 rural and ₹1000 urban (2011–12); shifted from calorie to expenditure-based poverty.

About C. Rangarajan Committee on Poverty Estimation:

  • Objective: To evolve a broader and realistic poverty metric incorporating food, health, education, clothing, and shelter costs, beyond calorie-based norms.
  • Overview: Formed by the Planning Commission in 2012, chaired by Dr. C. Rangarajan, former RBI Governor, to review India’s poverty measurement methodology.
  • Report Submission: Submitted in June 2014; became a major benchmark in the debate on India’s official poverty line and methodological framework.
  • Definition of Poverty: Based on Monthly Per Capita Expenditure (MPCE) ₹972 (rural) and ₹1,407 (urban) at 2011–12 prices, equating to ₹32/day (rural) and ₹47/day (urban).
  • Data & Methodology: Used Modified Mixed Reference Period (MMRP) consumption data with separate rural–urban baskets, adjusting for state-wise price differentials.
  • Poverty Estimate (2011–12): Found 29.5% of India’s population below the poverty line.
  • Key Revision over Tendulkar: Expanded consumption basket to include education, healthcare, rent, transport, and other essentials; replaced calorie-based with expenditure-based cost-of-living approach.

RBI 2025 Update (DEPR Study):

  • Source & Method: Conducted by RBI’s Department of Economic & Policy Research (DEPR) using HCES 2022–23 data for 20 states; retained Rangarajan framework.
  • New Price Index: Created a Poverty Line Basket (PLB) index instead of CPI reflecting actual consumption inflation more accurately.
  • PLB Composition: Rural PLB had 57% food share (vs 54% in CPI); Urban PLB had 47% (vs 36% in CPI).
  • Key Findings:
    • Rural Odisha poverty fell from 47.8% → 8.6%; Urban Bihar from 50.8% → 9.1%.
    • Lowest Poverty: Himachal Pradesh (0.4% rural), Tamil Nadu (1.9% urban).
    • Highest Poverty: Chhattisgarh (25.1% rural; 13.3% urban).
  • Significance: Confirms broad-based poverty decline yet highlights regional disparities; renews calls for a new official poverty line reflecting modern consumption trends.
[UPSC 2019] In a given year in India, official poverty lines are higher in some States than in others because
Options: (a) poverty rates vary from State to State
(b) price levels vary from State to State *
(c) Gross State Product varies from State to State
(d) quality of public distribution varies from State to State

Global Geological And Climatic Events

What are Transient Lunar Phenomena (TLP)?

Why in the News?

For centuries, astronomers and observers have recorded strange, short-lived visual events on the Moon’s surface, known as Transient Lunar Phenomena (TLPs).

Transient Lunar Phenomena (TLPs)

About Transient Lunar Phenomena (TLPs):

  • What is it: Short-lived flashes, glows, or hazy patches observed on the Moon’s surface, lasting seconds to several hours before fading.
  • Observation History: Reported for over a thousand years, including Apollo 11 astronauts (1969) who noted a luminous lunar glow.
  • Appearance Types: Include reddish glows, star-like flashes, and mist-like obscurations.
  • Active Regions: Concentrated around Aristarchus and Plato craters, considered the most dynamic lunar zones.
  • Scientific Implication: Suggests that the Moon remains geologically active, contradicting earlier assumptions of total dormancy.
  • Theories on Origin: Scientists propose several explanations for TLPs:
    1. Lunar Outgassing: Trapped gases such as radon or argon may escape through fissures, triggered by gravitational stresses or surface heating, causing dust or gas to glow or reflect sunlight.
    2. Meteoroid Impacts: Frequent meteoroid collisions on the Moon’s airless surface produce brief, intense flashes, accounting for many observed TLPs.
    3. Electrostatic Dust Levitation: Charged lunar dust particles, activated by solar radiation, may levitate and scatter light, producing transient luminous effects.
    4. Atmospheric Distortion on Earth: Some TLPs may be optical artifacts, caused by turbulence or refraction in Earth’s atmosphere altering the Moon’s apparent brightness or colour.

Recent Research and Monitoring:

  • Observation Technology: Use of automated telescopes and CCD (charge-coupled device) imaging systems for real-time detection.
  • Space Missions: NASA’s Lunar Reconnaissance Orbiter (LRO) and ISRO’s Chandrayaan series monitor gas release and new impact craters.
  • Spectroscopic Evidence: Studies of Aristarchus Plateau show episodic radon emissions, supporting the outgassing theory.
  • Integrated Monitoring: Global programs combine optical, seismic, and spectrometric data to validate events.
  • Scientific Aim: To understand lunar surface dynamics, internal processes, and signs of ongoing geological activity.

Wildlife Conservation Efforts

Indian wolf (Canis lupus pallipes) to be classified as new species by IUCN

Why in the News?

The IUCN has separately evaluated the Indian wolf (Canis lupus pallipes) from the gray wolf, suggesting it may be recognised as a distinct Canis species.

Indian wolf (Canis lupus pallipes) to be classified as new species by IUCN

About Indian Wolf (Canis lupus pallipes):

  • Overview: Also called the Peninsular Wolf or Indian Grey Wolf; proposed as Canis indica owing to genetic divergence 110,000–200,000 years ago.
  • Distinct Lineage: Genomic studies identify it as the oldest surviving wolf lineage, basal to all other Canis lupus subspecies.
  • Distribution: Found across Deccan Plateau, Gujarat, Rajasthan, Madhya Pradesh, Maharashtra, Karnataka, and Andhra Pradesh, extending into Pakistan and Iran; only 12.4 % of its range lies inside protected areas.
  • Population Status (2025): Estimated 2,877–3,310 individuals (IUCN Red List 2025) — classified as Vulnerable.
  • Legal Protection: Listed in *Schedule I of the Wildlife (Protection) Act, 1972, prohibiting hunting, trapping, or killing <citation needed>.
  • Habitat: Prefers scrublands, dry grasslands, and thorn forests, increasingly threatened by agriculture, solar projects, and highways.
  • Ecological Role: Functions as a top predator regulating prey such as blackbuck, chinkara, hares, and rodents in India’s open ecosystems.
  • Social Behaviour: Lives in packs of 6-8 members, exhibiting cooperative hunting and silent coordination strategies.

Evolutionary and Taxonomic Significance:

  • Early Divergence: Fossil and genetic data show divergence from Eurasian and Himalayan wolves well before the last Ice Age, evolving within India’s semi-arid zones.
  • Evolutionary Importance: Serves as a key model for studying wolf evolution, adaptation, and behaviour in tropical and dry environments.
  • Taxonomic Debate: Researchers propose recognition as a distinct species (Canis indica) based on unique genetic, ecological, and behavioural traits.
[UPSC 2024] Question: Consider the following statements:

Statement-I: The Indian Flying Fox is placed under the “vermin” category in the Wild Life (Protection) Act, 1972.

IMO’s 2023 Greenhouse Gas (GHG) Strategy

Why in the News?

The International Maritime Organisation (IMO) delayed a vote on its 2027 carbon pricing plan under the 2023 Greenhouse Gas (GHG) Strategy after U.S. pressure, stalling efforts for net-zero shipping by 2050.

What the IMO is trying to achieve?

  • Decarbonisation Goal: Targets net-zero emissions in global shipping by 2050, aligning with the Paris Agreement’s 1.5 °C limit; shipping contributes 2–3 % of global CO.
  • Carbon Intensity Reduction: Implements fuel-efficiency standards and CIIs to cut CO per tonne-mile of cargo transported.
  • Fuel Transition: Promotes shift from heavy fuel oil to green ammonia, methanol, hydrogen, and biofuels, supported by a global carbon pricing framework.
  • Equitable Transition: Upholds common but differentiated responsibilities, offering financial and technological aid to developing and island nations.
  • Market-Based Mechanisms: Developing carbon-pricing and fuel-levy systems to internalise environmental costs and fund innovation.
  • Regulatory Uniformity: Seeks to avoid fragmented regional rules (e.g., EU ETS) by maintaining global maritime emission standards.

About IMO’s 2023 Greenhouse Gas (GHG) Strategy:

  • Adoption: Finalised in July 2023 at Marine Environment Protection Committee (MEPC-80) (London) under the MARPOL Annex VI framework.
  • Carbon Intensity Targets: Cut 40 % by 2030 (vs 2008) and strive for 70 % by 2040.
  • Net-Zero Timeline: Achieve full sectoral decarbonisation by 2050.
  • Zero/Low-Emission Fuels: Ensure 5 % (aspire 10 %) of shipping energy from near-zero-GHG fuels by 2030; expand hydrogen and electrified propulsion.
  • Fuel & Emission Standards: Introduce Global Fuel Standard (GFS) and Global Pricing Mechanism (GPM) by 2027, covering ships above 5,000 GT (~85 % of emissions).
  • MRV Framework: Strengthen monitoring, reporting, and verification with emission databases and compliance audits.
  • Support Mechanisms: Establish GHG Fund to assist developing states in retrofits, technology adoption, and port upgrades.

Significance: 

  • Global Climate Milestone: First binding, worldwide roadmap for a high-emission transport sector outside aviation.
  • Regulatory Shift: Moves from voluntary action to enforceable standards in maritime law.
  • Strategic Impact: Positions the IMO as a key climate-governance body, linking trade regulation and environmental responsibility.

Arsenic Toxicity in Rice Cultivation

Why in the News?

A recent study has revealed that the composition of microbial communities in rice paddies critically determines the buildup of arsenic compounds in rice grains.

Arsenic Toxicity in Agriculture:

  • Overview: Arsenic (As) is a potent carcinogen and phytotoxin, bioaccumulating in rice and posing severe health and agronomic risks in Asian paddies.
  • Mechanism in Flooded Fields: Under anaerobic conditions, microbes convert arsenic into soluble, bioavailable forms that rice roots readily absorb.
  • Toxic Compounds: Organic forms like dimethylarsinic acid (DMA) and dimethylated monothioarsenate (DMMTA) cause straighthead disease, producing sterile, erect panicles and yield losses up to 70 %.
  • Speciation vs. Concentration: Toxicity depends on arsenic speciation, not total soil As levels, even low-As soils may cause poisoning.
  • Geographic Hotspots: Severe in West Bengal, Bihar, and Bangladesh, where arsenic-laden groundwater is used for irrigation.

About Soil Age and Microbial Composition:

  • Research Insight: Study by Peng Wang (Nanjing Agricultural University) shows soil age dictates microbial dominance and arsenic behaviour.
  • Young Soils (< 700 yrs): Dominated by arsenic-methylating bacteria that convert inorganic As into toxic organic forms (DMA, DMMTA).
  • Old Soils (> 700 yrs): Rich in demethylating archaea that detoxify As by breaking down methylated compounds.
  • Global Microbiome Survey: Across 801 paddy soils, identified 11 methylators and 6 demethylators as key toxicity predictors.
  • Risk Threshold: When methylator: demethylator ratio > 1.5, probability of straighthead disease rises sharply.

How does Microbial balance govern Arsenic toxicity?

  • Biological Equilibrium: Arsenic toxicity depends on balance between methylating bacteria (risk) and demethylating archaea (detoxification).
  • Environmental Triggers: Flood duration, oxygen, temperature, and hydrological shifts can tilt this balance toward higher toxicity.
  • Mitigation Measures: Mid-season drainage, silicon fertilisation, and microbial community management restore redox balance and reduce As uptake.

Air Pollution

What are Green Crackers?

Why in the News?

The Supreme Court of India has temporarily permitted the sale and bursting of green crackers in the Delhi–NCR region from October 18 to 21 for Diwali celebrations.

Background and Judicial Origin:

  • Trigger: Severe air pollution episodes during Diwali (2016–2017) pushed Delhi’s Air Quality Index (AQI) beyond 500, creating a public-health emergency.
  • Supreme Court Intervention (2018):
    • Affirmed that cultural freedom cannot override the Fundamental Right to Life (Article 21).
    • Banned conventional firecrackers containing heavy metals such as barium, lead, and mercury.
    • Directed CSIR to develop less-polluting alternatives, with PESO (Petroleum and Explosives Safety Organisation) tasked to test and certify them.
  • Outcome: Introduction of green crackers as a compromise solution balancing festive traditions with public-health protection.
  • Legal Oversight: The Supreme Court continues to monitor compliance, permitting use only within fixed time windows and under strict emission-control standards.

About Green Crackers:

  • Overview: Green crackers are eco-friendly fireworks developed by the Council of Scientific and Industrial Research – National Environmental Engineering Research Institute (CSIR-NEERI) to curb air pollution during festive celebrations.
  • Chemical Composition: Manufactured using modified formulations that exclude barium nitrate and significantly reduce sulphur and aluminium content, thereby cutting toxic emissions.
  • Emission Reduction: These crackers emit about 30 % less particulate matter (PM. and PM₁₀) and 10 % less sulphur dioxide (SO) and nitrogen oxides (NO) than conventional firecrackers.
  • Identification & Legality: Each authorised packet carries the Green Fireworks logo and a QR code verifiable through the CSIR-NEERI Green QR Code App; crackers without codes are illegal.
  • Purpose: Designed to retain the cultural and festive appeal of fireworks while mitigating health and environmental impacts in pollution-prone regions such as Delhi-NCR.

Types of Green Crackers:

  1. SWAS (Safe Water Releasable): Releases water vapour during combustion to reduce dust and temperature, lowering particulate emissions.
  2. STAR (Safe Thermite Cracker): Uses thermite-based reactions instead of conventional oxidisers, producing bright light and sound with reduced toxic output.
  3. SAFAL (Safe Minimal Aluminium): Limits metallic fuel content, maintaining luminosity and sound intensity while reducing aluminium and sulphur emissions.

All three maintain sound levels around 100–120 dB, comparable to traditional fireworks but with a cleaner emission profile and shorter atmospheric residence time.

Foreign Policy Watch: India-China

[18th October 2025] The Hindu Op-ed: Better global governance led by China and India

PYQ Relevance

[UPSC 2023] Virus of Conflict is affecting the functioning of the SCO.” In the light of the above statement, point out the role of India in mitigating problems.

Linkage: This PYQ is important as it tests India’s diplomatic balance within the SCO, amid regional rivalries. The article connects by showing how the Xi–Modi meeting and Global Governance Initiative reflect India’s role in restoring trust and strengthening multilateralism within the SCO framework.

Mentor’s Comment

As the world enters a phase of geopolitical churn and institutional fatigue, the call for a reformed, people-centric global governance system grows louder. The 75th anniversary of India-China diplomatic ties and the 80th year of the UN offer a historical moment: two Asian giants, once colonised, now rising powers, can redefine global order. For UPSC aspirants, this theme bridges multilateral diplomacy, global reforms, and India’s evolving foreign policy—key areas across GS Paper 2 and IR essays.

Introduction

The year 2025 marks a milestone in both bilateral and global history. India and China, home to over 2.8 billion people, commemorate 75 years of diplomatic relations, even as the United Nations celebrates its 80th anniversary. Against the backdrop of unilateralism and weakening multilateralism, the Global Governance Initiative (GGI) proposed by China, with India’s cooperation, offers a blueprint for a more equitable international order. As Asia’s two leading powers move from rivalry to partnership, their convergence could transform the world’s governance architecture, symbolising a decisive shift toward multipolarity and shared prosperity.

Why is the India-China cooperation in 2025 a landmark moment?

  1. Historical Context: The two leaders, Xi Jinping and Narendra Modi, have met 18 times since 2014, an unprecedented frequency symbolising sustained engagement despite border tensions.
  2. Symbolic Restoration: The bilateral meeting at the 16th BRICS Summit in Kazan (2024) and now at the 25th SCO Summit in Tianjin (2025) reflects a conscious reset in relations.
  3. Global Expectation: Their 19th meeting during the Tianjin Summit is being seen globally as a moment to restore balance to multilateral decision-making, especially amid Western dominance fatigue.
  4. Public Diplomacy: Both sides emphasise “partners, not rivals,” signaling a shift from competition to cooperation.

What is changing in the global governance discourse?

  1. Erosion of Trust: The early 21st century witnessed rising unilateralism, protectionism, and hegemonism, eroding faith in international institutions.
  2. UN at 80: The UN system, though foundational, now faces criticism for its limited representation of developing nations and sluggish response to global crises.
  3. Reform Imperative: The question before humanity is not just “who governs” but “how governance is shared.” The article highlights the need for reform without rupture, evolving existing systems rather than replacing them.
  4. Asia’s Moment: The decline of Western dominance and the rise of Asia and Eurasia are redefining the rules of the game, with India and China at the center.

What is the Global Governance Initiative (GGI)?

  1. New Vision: The GGI, announced by President Xi at the Tianjin SCO Summit, aims to correct the deficit in global governance by promoting a fair, inclusive order.
  • Five Core Principles:
    1. Sovereign Equality: Respect for all nations’ independence and dignity; greater democracy in international relations.
    2. Rule of Law: Equal application of international law and rejection of double standards.
    3. Multilateralism: Strengthening the UN as the core platform for global decision-making.
    4. People-Centric Approach: Governance should prioritise well-being, safety, and fulfillment of citizens globally.
    5. Real Results Orientation: Developed nations must shoulder more responsibility, while developing nations must cooperate for shared solutions.
    6. Essence: The GGI is not about creating parallel institutions but reforming and improving existing ones to respond effectively to modern challenges.

How can India-China cooperation strengthen multilateralism?

  1. Shared Responsibilities: Both countries, as major developing economies and SCO/BRICS members, bear the responsibility to defend international fairness and justice.
  2. Strategic Coordination: The leaders’ dialogue stresses communication on major international and regional issues to bridge divides in the Global South.

Complementary Visions:

  1. China’s “community of shared future for mankind
  2. India’s “Vasudhaiva Kutumbakam” (One Earth, One Family, One Future)
  3. Together, they embody the moral and developmental leadership needed for a post-Western global order.
  4. Practical Gains: Resumption of direct flights, maintenance of border stability, and enhanced trade cooperation show concrete steps toward normalisation.

What challenges lie ahead for India-China collaboration?

  1. Trust Deficit: Lingering border disputes and differing political models may slow strategic trust-building.
  2. Competing Ambitions: While both aspire to leadership in the Global South, perception management and narrative balance will be crucial.
  3. Western Reaction: The West may perceive India-China cooperation as a counterweight to transatlantic power, potentially complicating India’s strategic autonomy.
  4. Need for Institutionalisation: Long-term progress demands institutional mechanisms, track-II dialogues, multilateral coordination cells, and joint UN reform working groups.

Conclusion

The India-China partnership in 2025 signals more than a diplomatic milestone, it represents a potential rebalancing of world order. As the UN turns 80, the call for shared leadership between emerging powers grows urgent. If pursued with mutual trust and strategic maturity, the GGI-led collaboration can make the 21st century truly an Asian century rooted in equity, inclusivity, and sustainability. In a fractured world, cooperation, not competition, may be the only path to survival and progress.

Internal Security Architecture Shortcomings – Key Forces, NIA, IB, CCTNS, etc.

Gorkhaland statehood, Government names ex-DY NSA as interlocutor

Introduction

India’s federal architecture is unique: it allows the creation of new states to accommodate cultural, linguistic, administrative, or developmental aspirations under Article 3 of the Constitution. Yet, every statehood movement also reflects deeper struggles over identity, representation, and development.

The Gorkhaland issue, revived by the Centre’s recent move to appoint an interlocutor, is one of the oldest and most persistent among these. While it directly concerns the Darjeeling hills and adjoining areas of West Bengal, it mirrors similar aspirations voiced across India, from Vidarbha to Bodoland, Harit Pradesh, and Kukiland.

The Gorkhaland Appointment: Why is this news significant?

The Centre’s decision to name ex-Dy NSA Pankaj Kumar Singh as interlocutor for Gorkha talks is a politically charged step:

  1. First formal engagement in years: It revives official talks after a long hiatus, moving beyond ad hoc arrangements like the Gorkhaland Territorial Administration (GTA).
  2. High-level signalling: The appointment of a senior security expert signals that the government sees the issue as sensitive, with implications for internal security and electoral politics.
  3. Identity at stake: It concerns recognition of the Gorkha community’s distinct identity, and a permanent political solution to decades of protests and autonomy struggles.
  4. Pre-election dimension: With West Bengal Assembly elections approaching, the move is seen as an attempt to politically engage the hill electorate, which has historically swung between national and regional parties.
  5. Potential precedent: Success in structured dialogue may offer a model for addressing other regional aspirations through negotiation instead of agitation.

Understanding the Gorkhaland Issue

Historical Context

  1. Origins: The demand for Gorkhaland dates back to 1907, when the Hillmen’s Association first sought a separate administrative unit for the Nepali-speaking people of Darjeeling under British rule.
  2. Post-Independence Phase: With linguistic reorganisation (1950s), Nepali-speaking Gorkhas felt their identity was inadequately represented in Bengali-dominated West Bengal.
  3. 1980s Uprising: The movement, led by Subhash Ghising’s Gorkha National Liberation Front (GNLF), turned violent; it led to the creation of the Darjeeling Gorkha Hill Council (DGHC) in 1988 as a compromise.
  4. Second Wave: In 2007, Bimal Gurung formed the Gorkha Janmukti Morcha (GJM), renewing the demand; this led to the Gorkhaland Territorial Administration (GTA) in 2011, but unrest persisted.
  5. Present Phase: The latest talks under an interlocutor aim to find a “permanent political solution” and recognition of 11 sub-tribes as Scheduled Tribes.

Key Demands

  1. Separate Gorkhaland State: Carved out of Darjeeling and parts of Kalimpong, to ensure administrative autonomy and cultural recognition.
  2. Scheduled Tribe Status: For 11 Gorkha sub-tribes to ensure constitutional protections and socio-economic inclusion.
  3. Constitutional Recognition: Safeguards for the political identity and rights of the Gorkha people under the Indian Constitution.

Statehood Demands in India: The Bigger Picture

India has witnessed over 30 major statehood demands since Independence. While the Constitution empowers Parliament to reorganize states under Article 3, these movements have tested the balance between administrative efficiency, cultural autonomy, and political representation.

Why Do Statehood Demands Arise?

  • Cultural & Linguistic Identity:
      1. Key reason: Desire for recognition of unique language, ethnicity, or cultural practices.
      2. Examples: Gorkhaland (Nepali-speaking identity), Bodoland (Bodo tribes), Vidarbha (Marathi dialect and identity).
  • Developmental Disparities:
      1. Economic neglect and poor resource distribution often drive demands.
      2. Example: Telangana’s movement was anchored in perceived neglect by Andhra’s political elite.
  • Administrative Efficiency:
      1. Smaller states are believed to ensure better governance and resource management.
      2. Example: Creation of Chhattisgarh and Uttarakhand in 2000.
  • Political Representation & Power-sharing:
      1. Regional elites demand greater political space or autonomy to reflect local aspirations.
  • Ethnic Security and Integration:
    1. Fear of cultural assimilation or discrimination by dominant groups drives ethnic-based mobilisation (e.g., Bodoland, Kukiland, Karbi Anglong).
Year Movement Outcome
1953 Andhra State (Potti Sriramulu movement) First linguistic state formed
1960 Maharashtra & Gujarat Bombay Reorganisation Act
1972 Meghalaya, Manipur, Tripura New northeastern states created
1987 Mizoram & Arunachal Pradesh Granted full statehood
2000 Chhattisgarh, Jharkhand, Uttarakhand Created for administrative and developmental reasons
2014 Telangana Result of sustained agitation
Ongoing Gorkhaland, Bodoland, Vidarbha, Bundelkhand Unresolved, periodic agitations

Constitutional Mechanism for Creating New States

Article 3 empowers Parliament to form new states by altering the boundaries or names of existing ones.

Procedure:

  1. Process: Bill introduced in Parliament → Referred to State Legislature for views (not consent) Passed by simple majority.
  2. Centre’s Discretion: State opinion is advisory, not binding — ensuring national flexibility but sometimes triggering discontent.
  3. Examples:
    • Telangana was created despite Andhra Pradesh’s legislature opposing it.
    • Jharkhand was carved out of Bihar through a parliamentary process.

Challenges and Implications of Statehood Movements

  1. Political Fragmentation: Multiplying small states may weaken national coherence and increase Centre-State friction.
  2. Administrative Burden: Creating new bureaucratic structures increases fiscal costs.
  3. Resource Distribution Issues: Conflicts over rivers, minerals, and forest resources (e.g., Telangana-Andhra).
  4. Ethnic Competition: One community’s recognition can fuel new demands from others.
  5. Positive Outcomes: Improved local governance, targeted development, and better representation when well-implemented (e.g., Chhattisgarh’s success in rural health and PDS).

Lessons from Gorkhaland and Other Movements

  1. Need for Institutional Dialogue: Interlocutors and commissions reduce the risk of violent agitation by creating formal channels for negotiation.
  2. Multi-stakeholder Approach: Engagement should include Centre, State, local bodies, and civil society, not just political parties.
  3. Development-Based Solutions: Autonomy and identity must align with socio-economic development for long-term peace.
  4. Model for Others: If successful, the Gorkhaland dialogue could serve as a precedent for resolving other autonomy demands peacefully.

Conclusion

The Gorkhaland issue is not merely a regional agitation; it is part of India’s broader story of balancing unity with diversity, integration with autonomy, and identity with development. The Centre’s interlocutor initiative provides a constitutional, consultative path forward, one that aligns with India’s ethos of resolving internal aspirations democratically.

As India continues to evolve, the challenge will be to ensure that new demands for statehood or autonomy are addressed through dialogue, data, and development, not through division or delay.

Air Pollution

Rising carbon dioxide levels

Introduction

The atmospheric concentration of carbon dioxide (CO₂), the most significant greenhouse gas responsible for climate change, has increased by a record amount between 2023 and 2024, according to the World Meteorological Organization (WMO). The global average CO₂ concentration reached 423.9 parts per million (ppm) in 2024, 3.5 ppm higher than in 2023, representing the steepest one-year increase since records began.

This unprecedented rise coincides with 2024 being the hottest year on record, with average global temperatures 1.55°C higher than pre-industrial levels, breaching the 1.5°C limit scientists consider critical to prevent irreversible impacts.

Why This Is a Big Deal

This spike is unprecedented in modern climate history. Never before have CO₂ levels risen so sharply in a single year. It not only breaks the trend of relative stability observed over the last decade but also exposes the collapse of the global climate response despite the Paris Agreement. The rate of increase (3.5 ppm) is more than four times the average annual increase recorded between 2011 and 2020.

What makes this even more concerning is that both human-induced emissions (from fossil fuels, deforestation, and industrial activity) and natural feedback loops (like reduced ocean absorption and forest diebacks) are now amplifying each other, creating a self-perpetuating climate crisis.

What Is Driving the Surge in CO₂ Concentrations?

  1. Record-breaking increase: Global average CO₂ near Earth’s surface reached 423.9 ppm in 2024, marking a 3.5 ppm rise, the largest annual jump ever.
  2. Failure of climate frameworks: Despite international efforts under the Paris Agreement, emissions continue to climb, reflecting inadequate implementation and weak compliance.
  3. Global warming feedback: Higher temperatures reduce oceans’ capacity to absorb CO₂ and increase droughts and wildfires, releasing more carbon into the atmosphere.
  4. Burning of fossil fuels: Continued dependence on coal, oil, and gas remains the primary driver, responsible for more than 90% of anthropogenic CO₂ emissions.

How Are Natural Sinks Losing Their Absorptive Power?

  1. Reduced ocean absorption: Warmer oceans have absorbed less CO₂ in 2024 due to decreased solubility of gases in higher temperatures.
  2. Forest fires and droughts: A spike in wildfires and prolonged dry spells reduced the CO₂-absorbing capacity of trees and grasslands.
  3. Feedback loops: The decline of natural sinks worsens CO₂ imbalance, which in turn leads to even greater heat trapping and further degradation of these ecosystems.

How Do Other Greenhouse Gases (GHGs) Compare?

  1. Methane (CH₄): Second-most potent GHG, rose by 8 parts per billion in 2024 to reach 1,924 ppb, slightly below last decade’s average but still historically high.
  2. Nitrous oxide (N₂O): Increased by 1 ppb to 338 ppb in 2024, contributing to long-term warming effects due to its 270-year lifespan.
  3. Relative potency: While CH₄ and N₂O are more heat-trapping per molecule, CO₂ dominates because of its sheer volume and persistence in the atmosphere for thousands of years.

Why Is This Rise Unprecedented?

  1. Historical contrast: From the 1960s to 2010, CO₂ levels rose by 0.8 ppm per year; between 2011–2020, it increased by 2.4 ppm annually, far below the 2023–24 jump of 3.5 ppm.
  2. Crossing planetary limits: This rise pushed Earth past the 1.5°C warming threshold, previously considered a safe boundary.
  3. Interlinked causes: WMO attributes this to a mix of human emissions and natural CO₂ variability, indicating global climate systems are destabilizing.

Challenges for Global Climate Action

  1. WMO warning: The new data underscores the difficulty in curbing GHG accumulation in the atmosphere.
  2. Failure of control mechanisms: Despite decades of negotiations, anthropogenic activities continue unchecked.
  3. Feedback intensification: Natural processes, once climate stabilizers, are now acting as amplifiers of warming.
  4. Paris Agreement setback: The emission reduction targets for 2030 are unlikely to be met, while global temperatures already breached the 1.5°C mark.

Conclusion

The record-breaking surge in CO₂ levels between 2023 and 2024 is not just a statistical anomaly, it’s a planetary red alert. The intertwining of human actions and natural feedback loops signifies that climate change has entered a runaway phase unless drastic global mitigation is undertaken. The failure to meet emission targets and the collapse of natural carbon sinks highlight that the climate crisis is no longer a distant threat, it’s a present emergency demanding immediate collective action.

PYQ Relevance

[UPSC 2022] Discuss global warming and mention its effects on the global climate. Explain the control measures to bring down the level of greenhouse gases which cause global warming, in the light of the Kyoto Protocol, 1997.

Linkage: The article is important as it highlights the sharpest-ever rise in global CO₂ levels, signalling a critical climate tipping point and the failure of existing global frameworks like the Kyoto and Paris Agreements to curb emissions. It links directly with the question by showing how unchecked greenhouse gases are intensifying global warming and threatening climate stability.

  • A gold reserve is the gold held by a country’s central bank, acting as a backup for financial promises and a store of value.
  • India, like other nations, stores some of its gold reserves in foreign vaults to spread out risk and facilitate international trading.
  • India’s Gold Reserves:
    • As of the end of March 2024, the RBI held 822.10 tonnes of gold, with 408.31 tonnes stored domestically.
    • The share of gold in the total forex of India is around 7-8% as of 2023.

Where does the RBI store its gold?

  • India’s gold reserves are primarily stored in the Bank of England, which is known for its stringent security protocols.
  • The RBI also stores a portion of its gold reserves at the:
    1. Bank for International Settlements (BIS) in Basel, Switzerland, and the
    2. Federal Reserve Bank of New York in the United States.
During India’s foreign exchange crisis in 1990-91, the country pledged some of its gold reserves to the Bank of England to secure a $405 million loan, according to reports.

Even though the loan was paid back by November 1991, India decided to keep the gold in the UK for convenience.

Why does the RBI store its gold in foreign banks?

  • Convenience: Storing gold overseas makes it easier for India to trade, engage in swaps and earn returns.
  • Averting Risks: There are risks involved, especially during times of geopolitical tensions and war.
    • The recent freezing of Russian assets by Western nations has raised worries about the safety of assets kept abroad and the RBI decision to shift a portion of the gold reserve to India could be prompted by these concerns.
  • Stable Prices: Unlike fiat currencies, which can be subject to inflation or devaluation due to various economic factors, the value of gold tends to be relatively stable over time, which makes it an attractive asset for central banks to hold as a reserve.

Benefits Offered by Gold Reserves

  • Control domestic gold prices: With its big stash of gold, the RBI can help control local gold prices by using some of it in India. Last financial year, the RBI added about 27.47 tonnes of gold to the total reserve, bringing it to 794.63 tonnes.
  • Security buffer: The increased gold reserve works as a hedge against any financial crisis and to take measures to control inflation as well as currency devaluation.
[UPSC 2015] The problem of international liquidity is related to the non-availability of:

(a) Goods and services

(b) Gold and silver

(c) Dollars and other hard currencies *

(d) Exportable surplus

Global Geological And Climatic Events

Taftan Volcano, Iran 

Why in the News?

New satellite data in Geophysical Research Letters (October 2025) shows Iran’s Taftan volcano, dormant for 710,000 years, is reactivating.

Taftan Volcano, Iran 

About Taftan Volcano:

  • Location: Situated in southeastern Iran, about 56 km from the Pakistan border, within the Makran continental volcanic arc.
  • Elevation: Rises to 3,940 metres (12,927 feet), Iran’s only active volcano in the Makran arc.
  • Tectonic Origin: Formed by subduction of the Arabian oceanic plate beneath the Eurasian continental plate.
  • Volcanic Type & Composition: A stratovolcano composed mainly of andesitic and dacitic lava, with pyroclastic flows and volcanic breccias.
  • Structure: Features two summits, Narkuh and Matherkuh, and extensive ignimbrite and lava fans stretching over 30 km.
  • Hydrothermal Activity: Hosts sulfur-emitting fumaroles, visible from up to 100 km, sustained by an active hydrothermal system.
  • Eruptive History: Major activity phases around 8 Ma, 6 Ma, and 0.7 Ma; last lava flow dated to about 6,950 years ago.
  • Recent Observations: 2023–24 satellite data detected 9 cm ground uplift, indicating subsurface pressure buildup and reclassification from extinct to dormant.

Scientific Interpretation and Outlook:

  • Magma Dynamics: Uplift linked to gas accumulation or shallow magma intrusion at 490–630 m depth, possibly fed by deeper chambers (~3.5 km).
  • Current Status: No imminent eruption expected; likely pressure release via degassing or minor eruptions.
  • Monitoring Gap: Lack of ground-based GPS or seismic sensors; reliance on satellite InSAR data for deformation tracking.
  • Scientific Recommendations: Call for establishing a volcano observatory in southeastern Iran for real-time monitoring and gas analysis.
  • Regional Significance: Highlights Makran arc tectonic activity and underscores the need for international geophysical collaboration.
  • Research Importance: Taftan’s reawakening demonstrates the role of remote sensing in detecting hidden volcanic unrest and stresses continuous monitoring to assess eruption potential and regional hazard mitigation.
[UPSC 2024] Consider the following:
1. Pyroclastic debris 2. Ash and dust 3. Nitrogen compounds 4. Sulphur compoundsHow many of the above are products of volcanic eruptions?Options: (a) Only one (b) Only two (c) Only three (d) only four*
