    Unique Dolphin-Fisher in Ashtamudi Lake:

    • Cooperative Hunting: Dolphins herd fish towards artisanal fishers standing in shallow water.
    • Signals: Dolphins give tail-slaps or rolls to signal fishers to cast nets.
    • Mutual Benefit: Fishers get high catches; dolphins feed on escaping fish, forming a rare human–wildlife cooperation system.
    • Documentation: First studied by University of Kerala researchers; Similar systems studied in Brazil and Myanmar.
    • Expected Outcomes: Insights into animal culture, evolution of cooperation, and improved sustainable fishing practices.

    About Indo-Pacific Humpback Dolphins (Sousa plumbea):

    • Distribution: Found from East Africa to India, the Middle East and western Indochina, with major populations along India’s west coast.
    • Appearance: Identified by a large hump under the dorsal fin, dark grey plumbeous body, white mottling, and occasional pink shading; adults grow up to 2.8 m, newborns 97–108 cm.
    • Identification Traits: Long slender beak, dorsal fin perched on a mid-back hump, adults darken with age and often show shark-related scars.
    • Habitat: Prefer shallow waters (<20 m) within 1.5 km of shore; commonly near estuaries, river mouths, bays and nearshore fish concentrations.
    • Group Behaviour: Groups of 50–100 reported in India; shy but often seen during dolphin-watching trips.
    • Diet: Feed mainly on mullet, mackerel, sardines, pomfret and other schooling fish; sometimes exploit fishing nets, increasing entanglement risk.
    • Conservation Status: Vulnerable (IUCN), Appendix I (CITES), NOT LISTED under India’s Wildlife Protection Act (only Ganges and Snubfin dolphins are listed).
    • Colour Variation: Pinkish tint comes from superficial blood vessels used for thermoregulation; calves are dark grey.

  • Army sets up three new garrisons near the Siliguri Corridor

    Why in the News?

    India has set up three new Army garrisons at Dhubri, Kishanganj, and Chopra to secure the vulnerable eastern frontier and protect the Siliguri Corridor amid instability in Bangladesh and rising Chinese activity.

    Army sets up three new garrisons near the Siliguri Corridor

    About Siliguri Corridor:

    • Overview: A narrow land strip connecting mainland India to the Northeast, popularly called the Chicken Neck due to its thin, vulnerable shape.
    • Dimensions: Roughly 60 km long and 17–22 km wide, making it one of India’s most strategically sensitive corridors.
    • Location: Lies in northern West Bengal, bordered by Nepal (west), Bangladesh (south), Bhutan (north), with China’s Chumbi Valley close to the tri-junction.
    • Link to Northeast: The only land route for supplying all eight northeastern states, carrying road, rail, fuel, food and military logistics (except limited Bangladesh transit routes).
    • Strategic Sensitivity: Its narrowness and proximity to the India–China–Bhutan tri-junction make it a potential chokepoint in conflict scenarios.
    • Military Importance: Acts as the primary logistical artery for moving Indian Army troops and equipment toward Sikkim and Arunachal Pradesh, especially during LAC tensions.
    • Security Challenges: Surrounded by multiple international borders, making it prone to illegal immigration, smuggling, cross-border crime, and potential external military pressure.
    • Economic Significance: Key route for trade with Nepal and Bhutan, and supports tourism to Darjeeling, Sikkim and Bhutan.

    About the New Eastern Garrison Deployments:

    • Purpose: Developed to address rising security risks due to political changes in Bangladesh, demographic pressures along the border, and China’s increasing activity near the tri-junction.
    • Locations:
      1. Lachit Borphukan Military Station, Dhubri (Assam)
      2. Forward base, Kishanganj (Bihar)
      3. Forward base, Chopra (West Bengal)
    • Operational Role: Enables continuous surveillance, rapid troop movement, and strengthens defence preparedness across the India–Bangladesh frontier.
    • Local Support: Assam facilitated quick setup of the Dhubri station, named after Ahom general Lachit Borphukan, symbolising regional identity and military determination.

    Drivers Behind the Reinforcement:

    • Regime Change in Bangladesh: Expected shifts in border behaviour, cross-border movement, and potential security spillovers.
    • Illegal Immigration Concerns: Union Home Ministry has flagged demographic changes in border districts linked to cross-border inflow.
    • China’s Expanding Influence:
      • Accelerated LAC military build-up in Arunachal Pradesh.
      • Growing ties with Pakistan and Bangladesh, including a trilateral meet in Kunming, raising regional security concerns.
    • Regional Military Activity: India has conducted major exercises like Poorvi Prachand Prahar and IAF flying displays in Assam to signal operational readiness.
    • Pakistan–Bangladesh Engagements: Recent visit of a Pakistan Navy ship to Chattogram (first since 1971) has added a fresh strategic dimension to India’s eastern security planning.

  • Quantum Clocks and the Cost of Timekeeping

    Why in the News?

    A new study in Physical Review Letters finds that in quantum clocks the main cost of timekeeping comes from measurement rather than the clockwork itself, reshaping ideas in quantum metrology.

    What are Quantum Clocks?

    • Concept: Quantum clocks are timekeeping devices based on microscopic quantum systems whose transitions – atomic jumps, tunnelling events, or energy-level shifts – act as clock ticks.
    • Quantum Nature: Unlike classical clocks, their evolution is probabilistic, allowing temporary backward ticks due to quantum fluctuations while still needing a mechanism to mark irreversible flow of time.
    • Irreversibility Requirement: A functional clock must create a permanent record distinguishing past from future, despite underlying reversible quantum dynamics.
    • Role of Measurement: Their precision depends on both internal quantum transitions and the classical measurement system used to read them, since measurement converts quantum events into usable time signals.
    • Double Quantum Dot Model: In setups using double quantum dots (DQDs), a single electron tunnels between two nanoscale sites; each tunnelling event forms a discrete tick.
    • Quantum Dot Basis: Quantum dots – recognised by the 2023 Nobel Prize in Chemistry – can confine single electrons precisely, enabling well-resolved quantum transitions.
    • Entropy and Precision: The clock’s internal entropy rises with precision; at equilibrium (equal forward and backward ticks), entropy is zero and the system loses its ability to mark time.

    Recent Findings and Implications:

    • New Demonstration (2025): A Physical Review Letters study built a working quantum clock using a double quantum dot and separately measured entropy from the clockwork and from the measurement process.
    • Key Result: The entropy generated by measurement (via DC sensing and RF reflectometry) was nine orders of magnitude higher than the entropy needed for the electron-tunnelling clock itself.
    • Zero-Entropy Clockwork Still Works: Even when the quantum system produced no entropy, continuous measurement still created an irreversible classical record, allowing timekeeping.
    • Core Insight: The arrow of time in quantum clocks arises mainly from the classical measurement interface, not from the quantum dynamics.
    • 2023 Theoretical Link: Supports earlier findings that quantum measurement is inherently invasive and energy-costly, and that increasing measurement frequency does not always improve accuracy.

    Implications:

    • Thermodynamic Cost: Extracting information from any quantum system has an energy and entropy cost, affecting quantum sensing, quantum metrology, and clock design.
    • Application Outlook: Ultra-precise atomic clocks may be improved by lower-entropy measurement systems, leading to more efficient next-generation timekeeping.
    • Quantum Technologies: Insights are crucial for scalable quantum computers, where reading qubits must be precise yet thermodynamically minimal.
    • Conceptual Implication: Suggests that the microscopic arrow of time emerges from creating readable, irreversible records, rather than solely from quantum evolution itself.
    [UPSC 2022] Which one of the following is the context in which the term “qubit” is mentioned?

    Options: (a) Cloud Services (b) Quantum Computing* (c) Visible Light Communication Technologies (d) Wireless Communication Technologies

     

  • [15th November 2025] The Hindu Op-ED: Flexible inflation targeting, a good balance

    Mentor’s Comment

    The debate on India’s Flexible Inflation Targeting (FIT) framework is central to macroeconomic stability, especially as the Reserve Bank of India (RBI) undertakes the second quinquennial review after adopting FIT in 2016. This article decodes the logic, data trends, inflation-growth dynamics, concerns over inflation bands, and the evolving economic context, translated into UPSC-ready analysis with conceptual clarity.

    Introduction

    India adopted the Flexible Inflation Targeting (FIT) framework in 2016, giving statutory autonomy to the RBI for price stability. With the current inflation band of 4% ± 2% up for review in March 2026, economic debate has intensified on whether this band remains appropriate amid structural shifts, supply-side shocks, and the inflation-growth trade-off. The article evaluates India’s experience with FIT, evidence from inflation-growth relationships, and the question of acceptable inflation levels for sustained macroeconomic stability.

    Why in the News?

    The FIT framework is undergoing its second major review since its inception in 2016, making it a crucial moment for India’s monetary policy architecture. RBI has released a research discussion paper, its most comprehensive assessment yet, presenting long-term inflation-growth data, the first such empirical mapping since 1991. The debate is significant because India’s inflation has remained near the upper tolerance band, raising questions about whether 4% is still an appropriate central target or whether persistent supply shocks require rethinking the framework. The outcome of this review will shape India’s monetary autonomy, fiscal-monetary coordination, and growth stability over the coming decade.

    What makes inflation control central to monetary policy?

    1. Inflation as a regressive tax: Disproportionately burdens poorer households whose incomes are not hedged; erodes purchasing power.
    2. High inflation leading to misallocation of resources: Leads to volatile investments and misdirected economic decisions.
    3. Acceptable inflation evolves with context: The Chakravarty Committee (1985) recommended 5% as acceptable, but economic conditions have since changed.
    4. Institutional strengthening since 1994: Post-automatic monetisation era gave RBI functional autonomy; FIT (2016) gave statutory backing for price stability.

    How does India’s current FIT framework work?

    1. Inflation band of 4% ± 2%: Offers flexibility while anchoring expectations.
    2. Headline inflation as target: Encourages investment protection from supply shocks; aligns with international norms.
    3. Range-bound inflation despite shocks: India has broadly maintained inflation within the band, reflecting maturing policy credibility.
    4. Mechanism evolves with economic complexity: Framework still young, but institutional autonomy makes it robust.

    What should India target-headline inflation or core inflation?

    1. Headline inflation captures supply shocks: Essential in an economy where food inflation significantly affects households.
    2. Misconception on price behaviour: General price level (inflation) differs from relative price changes (e.g., wages, food).
    3. Milton Friedman example: Excess money supply raises general prices; changing relative prices without liquidity expansion cannot cause inflation.
    4. No liquidity expansion leading to no general inflation: Relative price movement alone insufficient to generate sustained inflation.

    What does long-term data reveal about inflation and growth?

    1. Quadratic inflation-growth curve (1991-2023): Presented in the article; first time excluding COVID years.
    2. Point of inflection = 3.98%: Growth rises with inflation to ~4%, then declines beyond it.
      1. Implication: India’s acceptable inflation level is just around 4%.
    3. Higher inflation hurts growth: Especially when supply constraints, fiscal stress, and external pressures coincide.

    How flexible should the inflation band be

    1. FIT performance so far: Delivered flexibility; monetary authorities operate near upper limit due to shocks.
    2. Risk of staying at the upper band: May undermine framework credibility.
    3. Policy navigation matters: India earlier faced high inflation in the 1970s-80s; monetisation of the deficit made it worse.
    4. Present framework avoids past mistakes: Moves away from fiscal dominance; prevents automatic deficit monetisation.

    What determines an acceptable level of inflation?

    1. Phillips Curve insights: Countries with higher income also see higher acceptable inflation levels.
    2. Empirical threshold near 4%: RBI paper’s curve suggests growth maximisation at around 4%.
    3. India-specific vulnerabilities: Supply shocks (food, fuel), climate variability, imported inflation, fiscal constraints.
    4. Need for robust expectations anchoring: Prevents wage-price spiral and demand misalignment.

    Conclusion

    India’s Flexible Inflation Targeting has broadly succeeded in stabilising inflation expectations while preserving monetary autonomy. Evidence from long-term inflation-growth dynamics reinforces that 4% remains an optimal central target, though India must build greater resilience to supply shocks and strengthen fiscal-monetary coordination. A credible, flexible, and data-driven FIT framework remains essential for India’s growth trajectory over the next decade.

  • Study on Lithium-Rich Red Giant Stars and Helium Abundance

    Why in the News?

    A recent study conducted by Indian Institute of Astrophysics (IIA) has discovered a link between Lithium-rich red giant stars and their enhanced helium abundance.

    What are Red Giant Stars?

    • Overview: Evolved stars that have exhausted core hydrogen, causing the core to contract and the outer layers to expand into a large, cool, reddish envelope.
    • Formation Process: Core contraction increases temperature while the outer shell expands and cools, triggering hydrogen shell burning.
    • Temperature and Luminosity: Surface temperature drops to 2,000–5,000 K, but luminosity rises sharply due to vastly increased radius.
    • Internal Fusion: Helium fusion begins in the core, producing heavier elements like carbon and oxygen.
    • Evolutionary Stage: Represents the late life cycle of medium-mass stars; the Sun will enter this phase in about 5 billion years.
    • End Stage: Outer layers are shed into a planetary nebula, leaving a white dwarf remnant that cools over time.

    Key Findings of the Study:

    • New Discovery: IIA established the first spectroscopic link between helium enhancement and lithium enrichment in red giant stars.
    • Data Source: Based on Himalayan Chandra Telescope observations and archival global spectroscopic datasets.
    • Sample Profile: 20 cool giants studied- 18 red giants and 2 supergiants.
    • Helium-Enriched Stars: Six stars showed high helium-to-hydrogen ratios (He/H > 0.1).
    • Distribution: Five were red giants and one a supergiant, showing a trend toward helium enhancement in lithium-rich giants.
    • Scientific Insight: Offers direct evidence of deep internal mixing and nucleosynthesis shaping surface chemical composition.

    What is the correlation between Lithium and Helium?

    • Coupled Enrichment: All helium-enhanced giants were lithium-rich, suggesting a shared internal mixing mechanism.
    • Asymmetry: Not all lithium-rich giants showed helium enhancement, implying lithium can rise without parallel helium increase.
    • Internal Mixing Role: Deep convection likely dredges up newly formed helium and lithium from the interior to the photosphere.
    • Photospheric Evidence: Confirms mixing-driven changes detectable on the stellar surface during the red giant stage.

    Significance of the Findings:

    • First Measurement: Provides the first direct spectroscopic photospheric helium estimates for normal and lithium-rich red giants.
    • Astrophysical Value: Refines understanding of mixing, nucleosynthesis, and energy transport inside red giant branch (RGB) stars.
    • Galactic Evolution: Improves models of how stars contribute heavier elements to the interstellar medium.
    • Methodological Advance: Strengthens indirect helium-measurement techniques for cool stars where helium lines are not visible.
    • Evolutionary Insight: Shows helium enrichment is integral to changes in luminosity, temperature evolution, and mass-loss pathways.

  • Holding up GLASS to India: securing stewardship to tackle AMR

    INTRODUCTION

    AMR in India is now labelled a “serious and escalating threat”, with the latest WHO GLASS report (2025) confirming extraordinarily high resistance levels across commonly used antibiotics. Nearly one in five severe infections in India mirrored or exceeded South and East Asian trends, and one in six confirmed infections was resistant. India’s high infectious disease burden, misuse of antibiotics, weak surveillance, and gaps in healthcare infrastructure continue to aggravate the problem. The article highlights incomplete data, insufficient funding, fragmented stewardship, and the urgent need for rational antibiotic use, surveillance strengthening, and affordable new-generation antibiotics.

    WHY IN THE NEWS? 

    India features prominently in the WHO’s October 2025 GLASS report, which confirms that the country now records some of the highest antibiotic resistance rates globally, particularly for gram-negative pathogens. For the first time, GLASS shows significant data gaps, reflected in India uploading surveillance results from only tertiary hospitals, leaving rural and peripheral areas undocumented. The report highlights a sharp contrast with global progress, exposing India’s limited surveillance expansion, weak stewardship, and slow adoption of newer effective antibiotics, despite AMR being among the country’s gravest public-health threats.

    Understanding the Scale of AMR in India

    1. High Resistance Rates: India shows disproportionately high resistance to commonly used antibiotics, especially in infections caused by E. coli, Klebsiella pneumoniae, Staphylococcus aureus, and pathogens causing sepsis in ICUs.
    2. Escalating Threat Category: WHO labels AMR in India as a “serious and escalating threat,” placing India among the highest global burden countries.
    3. Gram-Negative Pathogens: Severe risks emanate from resistance trends in gram-negative bacteria which limit treatment options in hospitals.
    4. Community-Hospital Gap: Surveillance primarily reflects tertiary hospital data, leaving a large rural and primary-care void, producing incomplete national estimates.

    Why Current Surveillance is Insufficient

    1. Incomplete Data Representation: GLASS data reflects only a segment of India’s population; peripheral, rural, and primary-care levels remain unrepresented, leading to erroneous conclusions.
    2. Fragmented Networks: Laboratories under NCDC’s AMR and AMRRSN networks provide data, but coverage is inadequate for a country of India’s scale.
    3. Operational Challenges: Shortage of trained microbiologists, inconsistent reporting, and infrastructure deficits weaken surveillance reliability.
    4. Underestimation of Burden: Without wider surveillance, actual AMR spread across different geographies or demographic groups remains unknown.

    Kerala’s State-Led Model of AMR Management

    1. State Action Plan Success: Kerala’s progress stems from early adoption of the State Action Plan aligned with India’s National Action Plan (NAP-AMR).
    2. Whole-of-System Approach: Kerala integrates veterinary, human health, and environmental data, demonstrating One Health operationalisation.
    3. Institutional Leadership: Dedicated stewardship committees and infection-control protocols ensure sustained monitoring and policy continuity.

    Antibiotic Stewardship and Public Awareness Challenges

    1. Unregulated Antibiotic Use: Easy over-the-counter access, self-medication, and incomplete courses contribute to rising resistance.
    2. Hospital Overuse: Lack of stewardship committees and infection-control practices deepen resistance in ICUs and emergency departments.
    3. Limited Community Awareness: Behavioural change campaigns remain inadequate, leading to misconceptions about antibiotic effectiveness.
    4. Inappropriate Prescriptions: Physicians often prescribe broad-spectrum antibiotics without culture sensitivity results due to delays or lack of labs.

    Innovation, R&D Pipelines and the Crisis of New Antibiotics

    1. Weak Domestic Innovation: Only 2 of the 32 antibiotics under global development meet WHO innovation criteria.
    2. Positive Trend: India’s CDSCO approved two new antibiotic candidates recently, while six others received global approval.
    3. Global Gap: Out of 97 candidates in preclinical pipelines (2022), few target WHO’s priority pathogens.
    4. High Barriers: Costly R&D, limited incentives, and delayed regulatory approvals weaken India’s innovation environment.

    Global and National Funding Gaps

    1. Insufficient Domestic Funding: India’s AMR response suffers from limited financial allocations, affecting surveillance expansion and lab capacity building.
    2. Gaps in Multilateral Support: Despite WHO’s Global AMR Challenge, LMICs like India lack sustained funding for new antibiotics and diagnostics.
    3. Need for Collaborative Platforms: Strengthened partnerships with bodies like the AMR Industry Alliance and CARB-X can accelerate innovation pipelines.

    Why Solutions Must Prioritise Stewardship, Surveillance, and Affordability

    1. Urgency of Behaviour Change: Stewardship requires both medical and community engagement to reduce irresponsible antibiotic use.
    2. Strengthening Peripheral Health Systems: Decentralised surveillance networks are essential to capture India’s actual AMR burden.
    3. Making New Antibiotics Accessible: India must prioritise affordability and availability given rising MDR (multi-drug resistant) infections in LMICs.
    4. Integrating One Health: Coordinated animal-human-environmental monitoring is indispensable for durable AMR containment.

    CONCLUSION

    India stands at a critical juncture where AMR has outpaced existing stewardship, surveillance, and innovation capabilities. The GLASS 2025 report acts as a mirror reflecting the country’s systemic gaps, from incomplete data and misuse of antibiotics to insufficient funding and slow R&D advancement. A robust national response must integrate strong stewardship, affordable innovation, decentralised surveillance, and a One Health framework to prevent AMR from becoming an unmanageable public-health catastrophe.

    PYQ Relevance

    [UPSC 2014] Can overuse and free availability of antibiotics without Doctor’s prescription be contributors to the emergence of drug-resistant diseases in India? What are the available mechanisms for monitoring and control? Critically discuss the various issues involved.

    Linkage: Because AMR is a recurring public-health crisis with direct links to governance, regulation, and science-tech, making it a favourite UPSC theme. The article shows rampant antibiotic misuse and OTC access driving India’s high resistance rates. This exactly reflects the PYQ’s focus on irrational use, weak monitoring, and stewardship gaps.

  • Urgent update: India needs to revise its CPI urgently

    Introduction

    The October retail inflation data exposed severe inaccuracies in India’s Consumer Price Index (CPI). While headline inflation appeared to fall to just 0.25%, the lowest since January 2012, the decline stemmed from a statistical anomaly, not real deflation. A collapse of 3.7% in the food and beverages index, driven largely by errors in price tracking during a month of actual food inflation (9.7%), dragged the entire CPI downwards. With outdated 2012 weights, GST-era distortions, and wide gaps between measured and perceived inflation, the CPI no longer mirrors reality. The article argues for urgent revision because the index now affects interest rate decisions, welfare planning, and fiscal strategy.

    Why in the news 

    Retail inflation for October collapsed to 0.25%, a 13-year low, appearing at first as a major success. But this fall was driven not by cheaper food but by a historic 3.7% contraction in the food and beverages category, despite actual food inflation touching 9.7%, the highest of the year. This sharp disconnect, caused by outdated weights and flawed price capture, marks one of the most serious statistical discrepancies in India’s CPI since its creation. With RBI’s interest rate decisions tied to CPI, this mismatch between measured inflation and lived inflation has become a significant policy challenge.

    What triggered the inflation anomaly in October 2025?

    1. Historic contraction in food index: The food and beverages category fell 3.7%, the largest drop since the 2012 CPI basket was created.
    2. Actual food inflation 9.7%: Prices in October rose steeply, showing complete divergence between data and reality.
    3. High weightage (46%): Because food accounts for nearly half of CPI, the flawed contraction pulled the entire index downward.
    4. Vegetable prices rising: The fall did not reflect market behaviour; vegetables had been getting costlier.
    5. Statistical anomaly: Not a reflection of cheaper food but a reflection of outdated measurement methods.

    Why is India’s CPI no longer accurate or representative?

    1. Outdated base year (2012): Consumption patterns, e-commerce, GST era changes, lifestyle shifts, none are captured.
    2. Misaligned weights: Household spending patterns have transformed; food no longer holds the same share.
    3. GST impact shows inconsistently: Only clothing and footwear showed inflation lower than last year due to GST cuts, not genuine price movement.
    4. Inconsistent category behaviour: Fuel, housing, tobacco, and miscellaneous inflation was higher than last year, contradicting the headline figure.
    5. Price capture errors: Data is often collected from markets that do not reflect actual consumer behaviour.

    What is the policy significance of this mismatch between CPI and real inflation?

    1. RBI’s rate decisions distorted: RBI surveyed households and found perceived inflation at 7.4%, far above the official CPI.
    2. Risk of wrong interest-rate moves: The RBI Monetary Policy Committee (MPC) uses CPI as its benchmark; incorrect CPI can lead to wrong rate cuts/holds.
    3. Poor signalling to markets: Bond markets, banks, and investors rely on accurate inflation forecasting.
    4. Impact on welfare schemes: Index-linked subsidies, pensions, and poverty estimates become inaccurate.
    5. Misleading economic narrative: Inflation is reported as low while households experience severe price stress.

    Why is a new CPI series urgently required

    1. Mismatch with GST regime: The GST tax cuts have altered category prices but CPI weights do not capture this.
    2. Structural change in Indian consumption: Electronics, services, digital expenses, mobility, none adequately represented.
    3. Incorrect urban-rural representation: Spending patterns in rural India have changed substantially.
    4. Temporary factors skewing data: GST rate cuts temporarily depress inflation readings, masking real trends.
    5. Government acknowledgment: Ministry of Statistics has confirmed work on a new CPI series.

    What is expected from the upcoming CPI revision?

    1. Greater accuracy: The new index will reduce the gap between statistical inflation and lived inflation.
    2. Improved weightages: Food weight may be reduced; services weight may rise.
    3. Better policy coordination: More accurate inflation data for monetary and fiscal decisions.
    4. Alignment with global practices: Frequent re-basing, digital data capture, and dynamic weighting.
    5. Timeline: Expected from the next financial year, improving CPI reliability.

    Conclusion

    India’s inflation measurement system is now at a breaking point. The October anomaly exposes the urgent need to modernize the CPI to reflect contemporary consumption and inflation realities. With monetary policy, welfare spending, and economic narratives relying on CPI, statistical distortions can lead to severe policy missteps. A revised CPI, updated, accurate, and GST-aligned, is essential for credible macroeconomic governance.

    Value Addition

    Consumer Price Index (CPI)

    • Definition: The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by consumers for a representative basket of consumer goods and services. The CPI measures inflation as experienced by consumers in their day-to-day living expenses.
    • Released by: National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI).
    • Frequency of release: Monthly, usually around the 12th of every month for the previous month.
    • What is included in the CPI basket:
      • Food & Beverages, Housing, Fuel & Light, Clothing & Footwear, and Miscellaneous services (education, health, transport, communication, recreation, personal care, etc.).
    • Weightage (CPI Combined, 2012 base year):
      • Food & Beverages: ~46%
      • Housing: ~10%
      • Fuel & Light: ~7%
      • Clothing & Footwear: ~6%
      • Miscellaneous: ~31%.

  • Centre releases draft Seeds Bill, 2025

    Why in the News?

    The Ministry of Agriculture and Farmers Welfare has released the Draft Seeds Bill, 2025 for public consultation before its introduction in Parliament.

    Precursor to the Draft Seeds Bill, 2025:

    • Seeds Act, 1966: Regulated seed production, certification, sale, and import/export through central and state seed committees and certification agencies.
    • Seeds (Control) Order, 1983: Added licensing requirements for dealers and expanded oversight of notified seeds.
    • Why Reform? Old laws could not address modern hybrids, biotechnology, private R&D, global seed trade, or digital traceability – creating the need for an updated, technology-ready statute.

    About the Draft Seeds Bill, 2025:

    • Objective: Ensure farmers get affordable, high-quality seeds while improving transparency and ease of doing business in the seed value chain.
    • Purpose: Replaces the Seeds Act, 1966 and Seeds (Control) Order, 1983 to regulate seed quality, curb spurious seeds, strengthen traceability, and modernise India’s seed sector.
    • Scope: Covers seed production, registration, import, sale, quality control, penalties, farmer rights, and digital monitoring.

    Key Provisions of the Draft Bill:

    • Farmer Rights: Farmers may grow, sow, save, use, exchange, share, or sell seeds of any registered variety from their own holdings, except when sold under a brand name.
    • Mandatory Registration of Varieties: All seed varieties meant for commercial sale must be registered (export-only and farmers’ own-use varieties exempt).
    • Registration of Seed Businesses: Producers (non-farmers), processing units, dealers, distributors, and nurseries must register with the designated authority.
    • Digital Traceability: Introduces a Central Seed Traceability Portal; seed packets must carry QR codes to monitor provenance and quality.
    • Graded Penalties: Trivial-to-major offences defined. Minor offences may get warnings; moderate offences attract fines up to ₹2 lakh; major offences (spurious/unregistered seeds) attract fines up to ₹30 lakh and/or imprisonment up to 3 years.
    • Seed Testing & Enforcement: Central and state seed labs can be established/recognised. Inspectors may sample, seize, inspect premises, and verify records.
    • Import Regulation: Imported seeds must meet germination and purity standards; trial and research imports require permits.
    • Ease of Doing Business: Minor offences decriminalised; compliance simplified while retaining strict penalties for serious violations.
