  • 39 Naga ancestral remains return home from Oxford

    39 Naga ancestral remains return home from Oxford

    Why in the News

    Naga ancestral remains kept in England for more than a century have passed from the custody of the University of Oxford to bodies of the Naga community itself. The university has transferred the custodianship of 39 Naga artefacts, including human remains, to a team from the Forum for Naga Reconciliation (FNR) and the Naga Tribe Hoho (NTH).

    What are the Naga ancestral remains, and how did they reach Oxford?

    1. What they are: The items are Naga artefacts that include human remains of Naga ancestors. Their return is like a family getting back an ancestor’s remains that an outside institution kept for generations.
    2. Where they were held: The University of Oxford’s Pitt Rivers Museum held them. The museum was established in 1884.
    3. How they got there: The museum received the artefacts from various collectors.
    4. The takeaway: Items catalogued as museum artefacts are ancestors to the community they came from, which is why the return matters beyond the count of objects.

    What has Oxford handed over, and to whom?

    1. What was transferred: The university handed over custodianship of the artefacts, meaning the responsibility for keeping and caring for them.
    2. Receiving team: Members of the FNR and the NTH formed the team that received them. The NTH is the apex body of all Naga communities.
    3. Handover ceremony: The two bodies stated that the Pitt Rivers Museum hosted the handover ceremony.
    4. Journey home: The remains are now returning to India. No date for their arrival has been stated.

    Why does the return matter?

    1. Milestone for the community: The handover is a milestone in the Naga community’s efforts to reclaim ancestral remains held in museums abroad.
    2. Community as custodian: The remains went to Naga community bodies. This recognises the community’s own claim over its ancestors.
    3. Colonial era collections: European museums built many such collections during colonial rule through collectors and administrators. Returns of this kind test how those museums deal with that past.

    Challenges

    1. No treaty cover for old collections: The 1970 United Nations Educational, Scientific and Cultural Organization (UNESCO) convention on illicit trade in cultural property does not reach objects removed before it took effect.
    2. Voluntary returns: Each museum decides for itself, so the pace of return varies from one institution to another.
    3. Thin records: Remains collected long ago often carry few details, which makes it hard to trace the village or clan they belong to.
    4. Wide agreement needed: Many Naga tribes are involved, so decisions on a final resting place need broad consent.

    Way Forward

    1. Community led decisions: The FNR and the NTH should settle the final resting place and rites in consultation with the tribes and villages concerned.
    2. Government facilitation: The Ministry of Culture and the Ministry of External Affairs should help with transport, clearances and documentation.
    3. Inventory of remains abroad: The Ministry of Culture should list Indian ancestral remains and sacred objects held in foreign museums.
    4. Record of the process: Document this handover so other communities and museums can follow the same route.

    Conclusion

    Care of the remains has passed to Naga bodies, and their journey to India is the next step. The date of arrival and the community’s decision on a final resting place are the things to watch.

    Back2Basics: Pitt Rivers Museum

    1. What it is: It is the University of Oxford’s museum of anthropology and world archaeology.
    2. Origin: It began with the collection that Augustus Pitt Rivers, a British army officer and archaeologist, gave to the university.
    3. Display method: It is known for arranging objects by type and use, not by region or period.

  • Strategic autonomy must guide India’s Starlink policy

    Strategic autonomy must guide India’s Starlink policy

    Why in the News

    The debate over Starlink’s entry into India has centred on Elon Musk’s charge that Indian “oligarchs” are impeding it. The government replied that all satellite operators follow the same regulatory process. The larger question is how much control India will have over Starlink, a matter of national security and strategic autonomy, the freedom to act without depending on another power.

    What is Starlink, and where does it fit in India’s networks?

    1. What it is: Starlink is the satellite internet service of SpaceX. It sends internet from satellites straight to a user’s terminal, like a mobile tower placed in the sky.
    2. Density versus reach: Fibre and mobile networks serve many people in one area. Starlink reaches remote places without towers or cables but serves few users per region, so it will not replace them.
    3. Best uses: Starlink suits isolated settlements, border regions, ships and disaster areas, and can connect soldiers, drones, sensors and command centres.
    4. The takeaway: Governments and the military need connectivity in exactly these places, so Starlink’s entry is a national security question.

    What control does India have over Starlink, and where does it fall short?

    1. Limited control: India can license and penalise Starlink, but SpaceX controls the satellites, software and terminal access. The network could stay on where India orders it off, or go off when most needed.
    2. Routing condition: Operators must route Indian user traffic through ground stations in India, called gateways. Links between satellites cannot be used to bypass them or to send Indian traffic through stations abroad.
    3. Monitoring and shutdown: Operators must give security agencies monitoring facilities and restrict connectivity on security related orders. Starlink has indicated willingness to comply and announced ground station sites in India.
    4. Enforcement gap: Authorities can inspect ground stations in India. Checking if traffic was routed or copied abroad depends partly on SpaceX’s own information.

    What do Iran and Ukraine show about controlling Starlink?

    1. Iran’s complaint: Iran has complained since 2023 to the International Telecommunication Union (ITU), the United Nations agency that coordinates radio frequencies, about unauthorised Starlink terminals on its soil.
    2. Limits of the regulator: In October 2026 the agency’s Radio Regulations Board again called for the transmissions to stop. It said it lacked authority to suspend the satellites’ assigned radio frequencies.
    3. Cooperation in Ukraine: In February, Ukrainian authorities and SpaceX identified authorised terminals and blocked those used by Russian forces. SpaceX acted on Ukraine’s requests, unlike in Iran.
    4. Disruption in Ukraine: On October 14, Ukrainian officials reported that Starshield, the military service built on Starlink technology, lost connectivity on terminals moving faster than about 160 km/h. This disrupted drone missions and frontline logistics.
    5. Contested cause: Ukraine’s President said the restrictions applied in Ukraine but not in European Union countries. Service returned on October 24, and the reason and responsibility remain contested.

    Why can India neither shut Starlink out nor depend on it?

    1. Cost of exclusion: Keeping Starlink out would cost remote regions valuable connectivity.
    2. American leverage: SpaceX depends on American regulatory approvals and government contracts, which gives Washington leverage over it. Eg. The Ukraine disruption coincided with Washington’s pressure on Ukraine to stop striking Russian oil refineries.
    3. Disputed order: One report traced the Ukraine restriction to the White House. The US President denied personally issuing it.
    4. Divergent interests: If American and Indian interests diverge in a crisis, this dependence becomes a strategic vulnerability for armed forces, emergency responders and essential services.

    Challenges

    1. Lost backup route: If Indian ground stations fail, the routing condition stops Starlink from rerouting traffic abroad, removing one backup.
    2. Limits of ground networks: Fibre and mobile towers cannot cover every ocean, mountain region or remote frontier.
    3. Weak rural broadband: Only 30% of gram panchayats had a functional connection under BharatNet, the rural broadband project, as of February 2026.

    Way Forward

    1. Strict licensing with better checks: India should retain strict licensing conditions and improve compliance checks as Starlink evolves.
    2. Tested backups: Military and essential users should keep backup connections and tested switching procedures.
    3. Multiple providers: Use several satellite internet providers from different jurisdictions.
    4. Wider ground coverage: Expand ground networks so fewer communities depend on Starlink alone.
    5. Domestic constellations: Encourage Indian satellite constellations (networks of many satellites), whose demand for satellites and rockets builds Indian industry.

    Conclusion

    A licence gives India legal authority over a foreign satellite network but not operational control of it. India needs enough alternatives, on the ground and in orbit, to keep essential communications working when one provider will not or cannot serve.

  • More women work but in informal and less secure jobs

    More women work but in informal and less secure jobs

    Why in the News

    The number of working women in India nearly doubled between 2017-18 and 2025, from 104 million to 201 million. The report ‘The Participation Paradox’ by the Indian Council for Research on International Economic Relations (ICRIER) finds most of the new work in farming, self employment and unpaid family labour, with shorter hours and lower relative pay.

    What is the ‘participation paradox’?

    1. What it is: Far more women are counted as working, but most new work is informal, low paid and insecure. It is like a school that doubles enrolment without adding classrooms.
    2. Data behind the report: The report uses the Periodic Labour Force Survey (PLFS), the government’s employment survey, and the Time Use Survey of how people spend their day.
    3. Gain from better counting: Women’s labour in fields and cattle sheds went mostly unrecorded for decades and is now counted.
    4. The takeaway: Counting shows how many women work, but the quality of the work decides whether their lives improve.

    Where has the new work for women come from?

    1. Female worker population ratio: The share of women who are working rose from 22% to 38%, mostly in rural India.
    2. Agriculture absorbs the surge: Rural women in crop and animal production rose from 54 million to over 100 million. Rural men left farming, the usual shift as an economy grows, called structural transformation.
    3. Informal work outside farms: Women’s other job gains were in garments, retail and construction, where work is largely informal and done in micro and own account enterprises (one person, no hired workers).
    4. Shift to self employment: Rural women in own account work quadrupled, and their share in regular salaried jobs slipped from 10.5% to 9.3%.

    What do hours and earnings show about the quality of this work?

    1. Falling hours: Weekly working hours fell for every group, most for rural women, by a little over six hours. Much new work is therefore marginal, filling only part of the week.
    2. Hours gap in textiles: In rural textiles, men’s lead in weekly hours widened from 11 to 21 hours. Many women there remain in home based or piece rate work, paid per item made.
    3. Widening wage gap: Women’s earnings rose but men’s rose faster. A rural woman now earns roughly 45% of what a rural man earns, down from 53%.
    4. Widest gaps where women work most: Per hour, men earn 2.1 times what women do in rural tobacco manufacturing. Women earn on par in about 20 urban sectors, which employ few women.

    Why does unpaid care work hold women back?

    1. Reason for staying out: 60% of women outside the labour force cite childcare and household commitments, against fewer than 1% of men. This has barely changed since 2021-22.
    2. Daily time gap: Women spent 3.7 hours a day more than men on domestic work in 2024, and nearly an hour more on care.
    3. Paid work adds to the load: Working women still spend around four hours a day on domestic work and nearly two on care. Working men spend under three hours on the two together.
    4. Limit of skilling: Skilling and job creation help only if women have time for them. Unpaid work at home absorbs that time and is not counted in national income.

    Challenges

    1. Uneven gains from growth: The gains from India’s structural transformation have gone largely to men.
    2. Maternity benefit gap: The Maternity Benefit Act, 1961 covers establishments with ten or more employees, which leaves out most self employed women.
    3. No paternity leave law: No central law gives private sector fathers paid paternity leave.

    Way Forward

    1. Lower care burden: Provide affordable, good quality childcare, and finance paid paternity and shared parental leave partly through social insurance (pooled contributions).
    2. Industrial policy that works for women: Support for Micro, Small and Medium Enterprises (MSMEs) should reward hiring women, with hostels and transport in textile parks.
    3. Paid work close to home: Create such work for rural women through local enterprise clusters, livelihood missions and women led producer organisations.

    Conclusion

    India now counts women’s work, but most of it remains informal, low paid and insecure. The next test is whether childcare, parental leave and enterprise support move women into better paid and more secure jobs.

    Key numbers

    1. Agriculture’s share in rural employment, 2017-18 to 2025: men 54.1% to 47.2%, women 70.7% to 73.3%.
    2. Urban women in agriculture: 2.6 million to 6.3 million, their largest employer.
    3. Men’s hourly earnings relative to women’s: 2 times in education, 1.8 in textiles, 1.7 in crop production.

  • World Bank’s poverty estimate does not pass the thali test

    World Bank’s poverty estimate does not pass the thali test

    Why in the News

    The World Bank has recently estimated “extreme poverty” in India at 2.6% of the population. A “thali index” built on the same survey data finds that roughly 30% of Indians cannot afford two meals a day, which puts the Bank’s poverty line for India in question.

    What is the World Bank’s poverty estimate, and how is it calculated?

    1. What it is: The estimate is a headcount ratio, the share of the population that is poor. It is like counting how many students in a class score below the pass mark.
    2. Poverty line: The pass mark is the poverty line, the minimum acceptable level of consumption. Anyone below it counts as poor.
    3. Survey data and goods basket: The Bank applies its line to the Household Consumption Expenditure Survey (HCES) 2023-24, which records household spending. Its report does not mention the goods and prices behind its India line.
    4. The takeaway: A poverty count is only as reliable as its line, so a line set too low hides real deprivation.

    What is the thali index, and what does it show?

    1. Thali index: The index counts how many thalis a person can buy with the monthly per capita food expenditure the survey records. Economists Pulapre Balakrishnan and Aman Raj proposed it in 2025.
    2. Why a thali: A thali is a complete meal of protein, carbohydrates and minerals that Indians relate to culturally.
    3. Price used: The index prices a thali at Rs 30. Rating agency CRISIL estimated this as the 2023-24 cost of a home cooked vegetarian thali, the cheapest kind.
    4. Finding: Up to 50% of rural Indians and 20% of urban Indians cannot afford two thalis a day.
    5. Effect of subsidised food: Adding the value of subsidised food lowers these shares to 40% and 10%, which gives the national figure of roughly three in ten.

    Why do the two measures differ when the data is the same?

    1. Different yardsticks: The Bank measures income poverty, which asks whether a person’s money reaches the poverty line. The thali index reads food consumption directly from the same survey.
    2. Food as a residual: Households pay rent, medicines and school fees first. Food gets what is left, so income above the line does not guarantee two meals.
    3. Implication for the line: If minimum food consumption decides who is not poor, the poverty line must be high enough to secure it. The index’s authors want the Bank to rethink its India line.
    4. Reach of the critique: The authors extend the objection to the Multidimensional Poverty Index (MPI) of the United Nations Development Programme (UNDP), to the extent it relies on the Bank’s line.

    Why does the estimate matter for policy?

    1. Complacency risk: A very low estimate tells policymakers that no action is needed. Low food consumption shows that action is urgent.
    2. Accelerating food inflation: Food prices decide how much people eat. Food price inflation rose every month from January to September and trebled over the period.
    3. More food at a steady price: Food inflation can be controlled only by producing more food at a steady price, which needs higher agricultural productivity.

    Challenges

    1. No current official line: India has not updated an official poverty line since 2011-12, so the Bank’s estimate has no domestic benchmark.
    2. One national thali price: A single thali price ignores price differences across States, villages and cities.
    3. Spending is not nutrition: A count of affordable thalis does not show what people actually eat.

    Way Forward

    1. Disclosure of the basket: The World Bank should publish the goods and prices behind its poverty line for India.
    2. Food anchored poverty line: The Union government should set an official line that secures minimum food intake after other essential costs.
    3. Food price policy review: The government should urgently review its food inflation policies and raise farm productivity.

    Conclusion

    India’s poverty count depends on where the line is drawn, and a line that ignores what households can actually spend on food understates deprivation. The line needs an anchor in food intake, and food prices need to be steadier.

    Poverty Estimation in India

    1. Monetary poverty lines: India’s consumption based lines came from the Lakdawala, Tendulkar and Rangarajan expert groups. The Rangarajan line was never adopted.
    2. International dollar line: The World Bank’s extreme poverty line is $3.00 a day at 2021 purchasing power parity, which adjusts for local prices.
    3. Multidimensional measures: NITI Aayog’s national index uses 12 indicators of health, education and living standards. The UNDP’s global index uses 10.

  • As demand overtakes supply, a big fat problem

    Why in the News

    India now faces a shortage of milk fat, not of milk. Demand for genuine ghee, khoya and paneer has risen, but milk increasingly comes from cows, whose milk carries less fat than buffalo milk. Butter prices at the dairy rose over 54% in three years, against 18% for skimmed milk powder (SMP).

    What is the milk fat problem?

    1. What it is: Milk is water plus two kinds of solids: fat, which makes ghee and butter, and solids not fat (SNF), the proteins, milk sugar and minerals left after the fat is removed.
    2. Joint products: Fat and SNF come together in every litre, like oil and oilcake from an oilseed. Producing more of one always brings more of the other.
    3. Milk supply is adequate: Total milk production has grown about 3% a year over the past decade. The shortage is in fat alone.
    4. Production success and fat gap: Policymakers made India the world’s top milk producer, but output of fat has not kept up with what consumers now want.
    5. The takeaway: A country can produce enough milk and still run short of fat if the mix of animals shifts.

    Why has demand for milk fat risen?

    1. Adulterated ghee: Some suppliers laced desi ghee with palm and other vegetable oils, or with animal fats such as tallow and lard.
    2. Regulatory crackdown: Crackdowns by the Food Safety and Standards Authority of India (FSSAI) and other regulators weakened these suppliers. Enforcement tightened most after the Tirupati laddu scandal of September 2024.
    3. Shift to genuine products: The crackdown raised demand for genuine ghee, khoya, paneer and other high fat dairy ingredients.
    4. GST cut: The Goods and Services Tax (GST) on ghee, butter and cheese has been cut from 12% to 5%.
    5. Incomes and awareness: Rising incomes and awareness of “real” milk fat have moved consumers away from frozen desserts made with vegetable oil and from analogue paneer (a paneer lookalike made with vegetable fat).

    Why is the supply of fat not keeping pace?

    1. Shift from buffaloes to cows: Growth in milk output is coming increasingly from cows. Buffaloes now contribute hardly 45% of national milk output, against 60% three decades ago.
    2. Lower fat in cow milk: Standard cow milk has 3.5% fat and buffalo milk 6.5%, so the same volume of milk now yields less fat.
    3. SMP surplus: Meeting fat demand through cow milk also produces more SNF, which is dried into SMP. The domestic SMP market is not expanding at the same rate.
    4. Resulting imbalance: India can end up with surplus SMP and a deficit in fat at the same time, which the gap between butter and SMP prices already shows.

    Challenges

    1. Farmer preference for cows: Crossbred cows give more litres per day than buffaloes, so farmers paid on volume choose them.
    2. Slow herd change: Buffaloes mature later and calve less often, so their numbers cannot be raised quickly.
    3. Unsold SMP stocks: Dairies holding surplus powder depend on volatile export prices to clear it.
    4. Stronger incentive to adulterate: Costlier fat raises the profit from mixing cheap vegetable oil into ghee.

    Way Forward

    1. Payment for fat: Dairies should pay farmers on fat and SNF content, not on volume, to reward milk richer in fat.
    2. Buffalo breeding: The Department of Animal Husbandry and Dairying should expand artificial insemination and breed improvement for high yielding buffaloes.
    3. Outlets for SMP: Dairies and the government should develop export and domestic uses for surplus powder.
    4. Sustained testing: FSSAI and State food regulators should keep up surveillance of ghee, khoya and paneer.

    Conclusion

    India’s dairy success was built on producing more milk, and its next test is producing the right mix of milk solids. Whether breeding and milk pricing begin to reward fat is the change to watch.

    Key numbers

    1. SNF content: 8.5% in standard cow milk and 9% in buffalo milk.
    2. Month of the GST cuts on dairy: September 2025, for ghee, butter, cheese, ice cream and paneer.
    3. GST on ice cream: Cut from 18% to 5%.
    4. GST on paneer: Cut from 5% to zero.
    5. Period of the price rise: October 2023 to October 2026, for both butter and SMP.

  • SC panel: Phase out ‘unsustainable’ river sand mining in 3 yrs, desilt dams

    SC panel: Phase out ‘unsustainable’ river sand mining in 3 yrs, desilt dams

    Why in the News

    The proposed answer to illegal river sand mining has moved from bans in specified areas to a three year phase out of “unsustainable” extraction from rivers, with sand dug from dam reservoirs meeting construction demand. The Supreme Court’s Central Empowered Committee (CEC), its expert panel on environment matters, recommended this in Report No. 36 of 2026, filed in the National Chambal Sanctuary sand mining case. The CEC admits it does not know how much usable sand dams hold.

    Why is river sand mining a problem, and what is the CEC’s answer?

    1. What it is: River sand mining is the digging of sand from riverbeds, mainly for concrete. The Supreme Court warned of its “disastrous effect” on river ecosystems.
    2. Nationwide scope: The Court took up the Chambal case on its own (suo motu). On October 6, a two judge Bench widened it to river sand mining nationwide and sought this report.
    3. Failure of bans: Rajasthan’s legal sand collection fell from about 57 million tonnes a year to 5 million after the Court restrained mining, an earlier CEC report found. This shortfall became illegal mining’s main driver.
    4. New roadmap: The CEC wants a time bound roadmap to phase out extraction from active river channels and develop alternatives, so that legitimate construction needs are still met.
    5. The takeaway: A ban without substitutes is like shutting a town’s only shop: buyers turn to the black market. The CEC seeks to replace river sand, not just stop it.

    What alternatives and monitoring does the report propose?

    1. Three alternative sources: The report names reservoir sediment, manufactured sand (M-sand) and recycled construction and demolition waste.
    2. M-sand: It is made by crushing suitable rock and can replace river sand in concrete when it meets Bureau of Indian Standards (BIS) specifications.
    3. Electronic transit permits: Anyone moving sand would need a secure electronic permit carrying a unique QR code, barcode or radio frequency identification (RFID) tag.
    4. State digital systems: State mining departments would track permissions, quantities permitted, actual extraction, transit permits and end use.

    How would dam desilting work?

    1. Dual purpose: Desilting removes sediment settled in a reservoir. It restores storage capacity and meets part of construction material demand.
    2. Storage already lost: Data placed before Parliament show 439 assessed reservoirs lost an average 19.24% of gross storage to sedimentation.
    3. Timeline: Contracts for eligible works would be awarded within three years, followed by a 10 year desilting cycle.
    4. Coverage: Storage dams over 15 years old that were never systematically desilted would be assessed. About one tenth of suitable reservoirs would be desilted each year, not every dam.
    5. Lead agency: The Ministry of Jal Shakti would lead a national framework with the Central Water Commission, the National Dam Safety Authority, the Environment Ministry and States.

    What does the CEC admit it does not know?

    1. Usable sand in dams: The potential of reservoir sediment as construction sand “has not been adequately assessed at the national level”.
    2. Sediment versus sand: Total sediment does not equal usable sand. Only some of it is technically recoverable, environmentally permissible or commercially usable.
    3. Scale of illegal mining: “No consolidated, reliable national database” records the volume or value of illegally extracted river sand.

    Challenges

    1. Distance from demand: Many reservoirs lie far from cities, so transport can make dam sand costlier than river sand.
    2. Unusable sediment: Much reservoir sediment is silt and clay unfit for concrete, and it needs safe disposal.
    3. Many authorities: Sand, a minor mineral, and water are State subjects, and mining rules, dams and enforcement sit with different State departments.

    Way Forward

    1. National sediment assessment: The Ministry of Jal Shakti should first assess how much recoverable sand each reservoir holds.
    2. Illegal mining database: The Ministry of Mines and States should build a national record of seizures and cases.
    3. Bhakra model and open sale: States can adapt the Bhakra Beas Management Board plan to excavate deposits up to two metres deep, and sell recovered sand through transparent mechanisms.

    Conclusion

    The CEC’s report is before the Supreme Court, with no date stated for a decision. Whether the Court turns the roadmap into binding directions is what to watch.

    Key numbers

    1. Reservoirs that lost over half their capacity: 23 (Ministry of Jal Shakti data, December 2025).
    2. Gobind Sagar storage: From 9,868 million cubic metres to about 7,300, a fall of 26%.
    3. Specified dams: 6,628 in the 2025 national register.
    4. Year of the earlier CEC report on Rajasthan: 2020.

  • Study: CO2 emissions from fossil fuels to decline this year

    Why in the News

    Carbon dioxide (CO2) emissions from burning fossil fuels are projected to move from 38.4 billion tonnes in 2025 to 38.2 billion tonnes in 2026, the first annual decline since 2020. The Global Carbon Budget study, released at the COP31 climate meeting in Antalya, Türkiye, links the dip partly to supply shocks from the conflict between the United States and Iran. India is the only major emitter whose emissions are expected to grow.

    What is the Global Carbon Budget, and what does it measure?

    1. What it is: The Global Carbon Budget is a yearly scientific count of the CO2 the world releases. It works like an annual account statement for the planet’s carbon emissions.
    2. Lead body and scope: The Global Carbon Budget Office at the University of Exeter leads the study. The headline number counts CO2 from burning fossil fuels (coal, oil and gas) only.
    3. One part of a larger basket: Fossil fuel CO2 is the dominant part, but only one part, of the greenhouse gases that cause global warming.
    4. The takeaway: A fall in fossil fuel CO2 does not by itself mean that the gases warming the planet are falling.

    What does the 2026 projection show?

    1. Global dip and its causes: Emissions are expected to be 0.4% lower than last year. The study credits disruptions to fuel supply caused by the conflict and the growing use of renewable energy.
    2. India’s rise: India’s fossil fuel emissions are likely to be 4.4% higher than last year. This is above the 3.5% average annual growth it registered over the last decade.
    3. Other major emitters: China, the United States, the European Union and Japan are expected to see declines.
    4. Earlier record: The last decline came in 2020 during the Covid pandemic, the biggest fall from one year to the next measured so far.

    Why is this decline not a climate solution?

    1. Shock driven fall: Researchers called the dip most likely a short term result of the ongoing conflict. The study’s lead said a reduction “driven partly by geopolitical shocks is not a sustainable climate solution”.
    2. Past dips reversed: Small declines in five earlier years were all tied to global disruptions that cut industrial activity and fuel use. Emissions resumed their rise after each.
    3. Clean energy as the lasting answer: Renewables and electric vehicles are increasingly offsetting growth in energy demand. Their rollout must speed up further for global emissions to peak and then keep falling.

    How far is the world from the 1.5 degree path?

    1. Paris target: The Paris Agreement aims to hold global warming within 1.5 degrees Celsius.
    2. Record greenhouse gases: The World Meteorological Organisation (WMO), the United Nations weather and climate agency, reported a new high in greenhouse gas emissions in 2025. Its State of the Climate Report points to a further rise.
    3. Cut required: Annual greenhouse gas emissions must fall by almost half from 2019 levels by 2030. Only then is there even a minimal chance of meeting the Paris target.
    4. Cut projected: Current projections show a reduction of not more than 2% by 2030, even in the best case.

    Challenges

    1. Reversal after the shock: Emissions that fell because fuel supply was disrupted can rebound once supply returns.
    2. India’s rising energy demand: India’s emissions are growing because its economy and electricity use are still expanding, with coal as the main power source.
    3. Gases beyond CO2: Methane and nitrous oxide, largely from agriculture, waste and fuel leaks, are not captured in the fossil fuel CO2 figure.

    Way Forward

    1. Faster clean energy rollout: Governments should speed up renewable capacity, storage and grids so that falling emissions do not depend on crises.
    2. Cleaner growth in India: India should meet new electricity demand mainly from solar, wind and storage to slow its emission growth.
    3. Action on methane: Countries should plug leaks from oil, gas and coal operations.

    Conclusion

    The projected dip in fossil fuel emissions reflects a disrupted fuel market more than a lasting change in how the world produces energy. Whether emissions stay down once the shock passes, and whether India’s growth in emissions slows, will show if a real peak has arrived.

    Key numbers

    1. Decline in the Covid year: 2% in 2020 (Global Carbon Budget).
    2. Earlier years of small declines: 1974, 1981, 1992, 1998 and 2009 (Global Carbon Budget).

  • Crackers account for 71% of Delhi’s PM2.5 on Diwali night: Data

    Why in the News

    For the first time, an official source apportionment estimate for Delhi’s air includes firecracker emissions, and it puts their share of PM2.5 at 71.1% in the hours after Diwali night. The assessment by the Indian Institute of Tropical Meteorology (IITM), Pune, rests on real time data. The estimate is indirect and covers only an eight hour window each day.

    What is source apportionment, and how was this estimate made?

    1. What it is: Source apportionment works out how much each source, such as vehicles, biomass burning or dust, adds to air pollution. It is like splitting a shared electricity bill appliance by appliance.
    2. Pollutant measured: The estimate covers PM2.5, fine particles of 2.5 micrometres or less that enter deep into the lungs.
    3. New laboratory: The Advanced Atmospheric Chemistry and Aerosol Toxicity Analysis Laboratory (AATAL) opened at IITM’s Delhi branch on October 24. It analyses the chemical composition of gases and aerosols (airborne particles), including PM2.5, metals and toxic elements.
    4. Integrated system: AATAL is linked to IITM’s Air Quality Warning and Integrated Decision Support System for Emissions (AIRWISE), which combines air quality forecasts, observations and source apportionment information.
    5. The takeaway: Delhi now has an official figure for a source earlier debated without measurement, which helps plan targeted interventions.

    What did the assessment find?

    1. Diwali night share: Firecrackers contributed 71.1% of Delhi’s PM2.5 in the study hours of November 9, just after the celebrations wound down.
    2. Build up before Diwali: The firecracker share in the same hours was 5.6% two days earlier and 43.4% on the night before Diwali.
    3. Regular sources displaced: Before Diwali night, secondary organic aerosols (particles formed in the air from gases) and biofuel burning led. Their shares fell sharply on Diwali night.
    4. Lingering effect: Firecrackers remained the top contributor a day later, at 29.8% in the study hours, followed by secondary organic aerosols and transport emissions. Delhi’s Air Quality Index (AQI) was 299, in the “Poor” category.
    5. Peaks at monitoring stations: PM2.5 peaked at 4,985 micrograms per cubic metre in Jahangirpuri and 2,808 in Nehru Nagar in the early hours after Diwali night.

    Why is the estimate uncertain?

    1. Indirect estimation: No real time measurement of firecracker aerosols exists, so their impact is estimated indirectly. IITM says it used the best available source profiles and established methods.
    2. Episodic source: Firecracker emissions come in bursts, unlike continuous sources such as vehicles. Their concentration shifts with the timing and intensity of bursting, wind speed and atmospheric mixing.
    3. Boundary layer height: The height of the planetary boundary layer (the lowest layer of the atmosphere) decides whether pollutants disperse or accumulate close to the ground.
    4. Tracer overlap: Potassium is the common chemical marker (tracer) for fireworks, but biomass burning, including crop residue and wood, also releases it. A study this year found the two mixing into a “complex, chemically evolved haze”.
    5. Variation across locations: A 2022 study of two Delhi sites about 15 km apart found substantial differences in fireworks related elements.

    Challenges

    1. Limited window: The estimate covers only 1 am to 9 am for each date, not the full day’s contribution.
    2. Chemical overlap with age: Separating firecracker particles from other smoke gets harder as pollutants age and mix in the atmosphere.
    3. Enforcement in one night: Curbs on bursting firecrackers are hard to police across an entire city within a few hours.

    Way Forward

    1. Full day estimates: IITM should extend the apportionment from the eight hour window to the full day.
    2. More measurement sites: Add chemical analysis at several locations, since firecracker impact differs across the city.
    3. Advance warnings: Delhi’s agencies should use AIRWISE forecasts to time curbs before Diwali night.

    Conclusion

    Firecrackers now have a measured place in Delhi’s official pollution accounts, with stated limits on how far the figure can be read. Whether next season’s curbs are planned on this evidence is what to watch.

    Key numbers

    1. Leading shares before Diwali night: Secondary organic aerosols 20.8%, mixed or unresolved biofuel burning 18.1%.
    2. Other shares before Diwali night: Waste burning 11.6%, secondary inorganic aerosols 10.3%, vehicles 8.8%.
    3. Shares on Diwali night: Vehicles 6.9%, secondary inorganic aerosols 5%, secondary organic aerosols 4.5%, waste burning 1.1%.
    4. Time of the PM2.5 peaks: 3 am on November 9, at both stations.

  • India’s efforts to clean its air need not slow its economic growth

    Why in the News

    India ranked 176 of 177 countries in the 2026 Environmental Performance Index (EPI), published by Yale and Columbia Universities, and performed worst on air quality. The question it raises is whether pollution can fall fast enough as the economy keeps growing. China’s record shows that pollution control need not wait until growth is complete.

    Why does cleaning the air look like a choice against growth?

    1. What the tradeoff is: The activities that pollute the air also drive development. It is like a stove that cooks the family’s meal and fills the room with smoke.
    2. Sources tied to development: Industries create jobs, power plants supply electricity, transport moves goods and agriculture supports livelihoods. Cutting their emissions costs money and needs technology that users can afford.
    3. Health burden: The State of Global Air 2025 report attributed more than 20 lakh deaths in India in a single year to air pollution.
    4. The takeaway: India’s test is whether pollution falls faster than polluting activity grows.

    What does China’s experience show?

    1. Early industrial controls: China tightened industrial emission controls during rapid economic growth. Emissions of sulphur dioxide (SO2) fell 14% in the five years to 2010.
    2. Clean air campaign: Research found that emission controls under a later, broader campaign, not weather alone, caused most of Beijing’s fall in PM2.5 (fine particles) during 2013 to 2017.
    3. Limits of the comparison: China’s institutions, economy and energy systems differ from India’s, so India cannot copy its approach.

    Why is counting clean technologies not enough to judge progress?

    1. Net effect test: India is adding renewable power, electric vehicles and cleaner cooking fuels. Progress depends on whether together they offset the growth in polluting activities.
    2. Rising electricity demand: The International Energy Agency (IEA) expects India’s electricity demand to grow 6.4% a year through 2030. Solar is expected to meet around half of it and coal about one quarter.
    3. Thermal power norms: In July 2025, the Union government revised SO2 norms for coal and lignite power plants. One category kept mandatory standards, a second gets case by case review and a third conditional exemption.
    4. Grounds cited: The government cited technical feasibility, electricity prices, water and limestone use and carbon emissions. The cost is that SO2 also forms secondary fine particles.

    What do the National Clean Air Programme results show?

    1. PM10 gains: 108 of 130 cities under the National Clean Air Programme (NCAP) recorded lower annual PM10 (coarser particles) than eight years earlier.
    2. Limits of the evidence: A PM10 fall does not show a similar PM2.5 trend. Weather and changing emission profiles also move the numbers, so policy alone cannot take the credit.
    3. Performance linked funds: NCAP cities have received Rs 16,423.55 crore tied to their performance.

    How should clean air action be judged?

    1. Allied programmes: Pradhan Mantri Ujjwala Yojana (household fuel), PM E-DRIVE (transport) and PM Surya Ghar (electricity) also cut emissions, but cleaner air is not their only objective.
    2. Shared benefits: Cleaner industrial processes improve energy efficiency, clean cooking improves health and better waste management improves urban services. Such gains should be shown explicitly.
    3. Investment and outcome: A larger budget shows more activity, not more mitigation. Each measure should be judged on the pollution it prevents, its cost and whether exposure declined.

    Challenges

    1. Visible costs, delayed benefits: Pollution control costs are immediate and concentrated, but health benefits are spread widely and emerge over time.
    2. Access without sustained use: Access to liquefied petroleum gas (LPG) does not guarantee use, because fuel prices and household income decide what families burn.
    3. Pollution across boundaries: Polluted air crosses city and State boundaries, but clean air plans are drawn city by city.

    Way Forward

    1. Outcome linked funding: The Environment Ministry should release NCAP funds against measured falls in PM2.5, not money spent.
    2. PM2.5 reporting: Cities should publish annual PM2.5 trends alongside PM10.
    3. Refill support: Keep LPG refills affordable for low income households.

    Conclusion

    India’s clean air effort adds programmes and funds faster than it proves their effect on the air people breathe. Whether future spending is judged by exposure reduced, not by activity launched, is what to watch.

    Key numbers

    1. EPI coverage: 47 indicators across 12 categories (2026).
    2. India’s EPI air ranks: 175 on air quality and 88 on air pollution.
    3. Industry’s share of new power demand: Roughly a third through 2030 (IEA).
    4. Air pollution deaths, year counted: 2023.
    5. NCAP periods: PM10 compared for 2025-26 against 2017-18; funds from 2019-20 to 2025-26.

  • Antalya agenda: Climate funds, energy transition

    Why in the News

    For the first time, one country hosts a United Nations climate summit and another runs its negotiations: Turkey is president and host of COP31, and Australia holds “exclusive authority” over the formal talks. COP31 has opened in Antalya as the first summit since the United States left the Paris Agreement, and developing countries including India are pressing for the finance developed countries owe.

    What is COP31, and how does it take decisions?

    1. What a COP is: The Conference of the Parties (COP) is the annual meeting of countries that signed the 1992 United Nations Framework Convention on Climate Change (UNFCCC).
    2. Three meetings in one: Alongside COP31, Antalya hosts the meetings of Parties to the Kyoto Protocol (CMP21) and to the Paris Agreement (CMA8).
    3. Paris Agreement duties: Every country submits a nationally determined contribution (NDC), its own climate plan, every five years, to hold warming well below 2°C and pursue 1.5°C.
    4. Consensus rule: Decisions need consensus, so a single country can hold up an agreement.
    5. The takeaway: COP31 will not produce a landmark treaty, so the contest is over delivering finance, measuring progress and speeding the energy shift.

    What is different about COP31?

    1. Origin of the split presidency: The “Western European and Others” group had the 2026 turn to host. Turkey and Australia both bid, and the standoff ended in a power sharing deal.
    2. Division of roles: Turkey handles the venue, logistics and the “Action Agenda” of voluntary pledges. Australia steers the formal talks, the drafting of texts and the decisions.
    3. United States exit: The largest historical emitter is absent from finance talks, so developing countries want Europe and others to fill the gap.

    What is on the table, and who leads each track?

    1. Mitigation: India and Germany chair consultations on countries whose 2035 plans fall short of 1.5°C, and on what “transitioning away from fossil fuels” requires.
    2. Finance and adaptation: France and the Philippines lead on existing finance commitments. Britain and Sierra Leone lead on tripling finance for adapting to climate impacts and readying the Global Goal on Adaptation (GGA) for COP32.
    3. Just transition and oceans: Mexico and Poland lead on the just transition mechanism (help for affected workers and communities), and Palau and Canada on oceans.
    4. Electrification pledge: Turkey wants a pledge to raise electricity’s share of global final energy use from about 23% to 35%.
    5. Article 9.1 and equity: Developing countries including India want Article 9.1 of the Paris Agreement, the finance duty of developed countries, on the agenda. They want coal pressure to respect “common but differentiated responsibilities and respective capabilities“, meaning heavier duties for richer countries.

    What did COP30 at Belém leave unfinished?

    1. Global Mutirao: COP30 in Brazil closed with the “Global Mutirao” (collective effort) package. It sought tripled adaptation finance by 2035, five years later than developing countries wanted and with no clear baseline.
    2. Finance roadmap: The Baku to Belém Roadmap aims at $1.3 trillion a year of climate finance for developing countries by 2035.
    3. COP29 goal: The roadmap builds on the goal of $300 billion a year set at COP29 in Baku.
    4. Belém initiatives: COP30 adopted “Belém indicators” to measure progress on the GGA. It also adopted a Global Implementation Accelerator and a “Belém Mission to 1.5“.
    5. Fossil fuel gap: Over 80 countries backed a roadmap away from fossil fuels, but the final text cited only the 2023 “UAE Consensus“. Colombia and the Netherlands launched the Santa Marta process in April this year.

    Challenges

    1. Finance: Tripling adaptation finance has no numbers or timeline behind it, and the roadmap has no monitoring system.
    2. Fossil fuels: The negotiated text can again omit a transition away from fossil fuels.
    3. Electrification pledge: The pledge counts only if enough countries sign on to “35% by 2035”.
    4. Split presidency: Nobody knows who decides if Turkey and Australia disagree in the closing hours.
    5. Global South bargain: Developing countries want the Article 9.1 discussion and finance reforms in return for engaging on mitigation.

    Way Forward

    1. Dated finance commitments: Developed countries should state yearly amounts and a baseline for adaptation finance.
    2. Rules for the presidency: Turkey and Australia should publish how their disagreements are settled.
    3. Mitigation linked to finance: India and Germany should pair each ask on 2035 plans with a finance commitment.

    Conclusion

    Antalya will be judged less on headline pledges than on whether earlier promises turn into finance and action. The conference runs till November 20, and the developing countries’ demand on finance obligations is the outcome to watch.
