  • Bird islands

    Why in the News

    Two male Great Indian Bustards have been released into the wild at the Desert National Park in Jaisalmer, under a conservation plan that now holds 97 birds. It is a rare gain for a species of about 120, but India still protects single species in enclosed pockets rather than whole landscapes.

    What is the Great Indian Bustard programme, and why was it needed?

    1. What the programme does: The Great Indian Bustard (‘Godawan’) is a heavy Rajasthan grassland bird. The plan breeds it in captivity for release, like a nursery raising saplings.
    2. National bird debate: Salim Ali wanted it named the national bird so that protection would follow. The Indian Board for Wildlife chose the peacock.
    3. Why it was needed: The bird numbered about 1,260 in 1969 and has been close to extinction for nearly half a century, pushed down by:
      • hunting, royal hunts included, into the late 1970s;
      • irrigation, turning grasslands once dismissed as ‘wastelands’ into pesticide-soaked fields and roads;
      • power lines, the most recent threat.
    4. The takeaway: Captive breeding can lift numbers, but it does not undo the habitat loss that caused the decline.

    What has the breeding plan achieved?

    1. Captive-bred stock: 57 birds in the plan are captive-bred, and nine more await release.
    2. Breeding output: The captive-bred birds produced 29 chicks this year, up from 24 last year.
    3. Ceremony: The Union and Rajasthan Environment Ministers attended a release marked by “considerable bureaucratic pomp”.

    Why were power-line protections narrowed?

    1. Collision risk: The heavy, poor-sighted bustard flies at the height of high-tension lines, so wires in its path endanger it.
    2. Supreme Court order, 2021: The Supreme Court ordered that low-voltage lines in the bird’s priority habitats be laid underground.
    3. Modified order: Renewable energy companies objected that undergrounding raised the cost of solar power. The Court then limited the order to lines in the bird’s narrower ‘critical’ habitat.

    Why is species-by-species conservation falling short?

    1. Neglected birds: The Godawan now features in government and private marketing, but most get no such attention. Nearly 1,256 bird species, about 11.5% of the world’s total, are threatened.
    2. Common birds in decline: Skylark numbers have fallen nearly 80% in 12 years.
    3. ‘Captive to symbolism’: India’s policy favours showcase moves over habitats:
      • a tigress from Valmiki flown to Buxa;
      • African cheetahs kept in enclosures;
      • Gir’s lions confined to Saurashtra and straying into villages;
      • the Delhi Ridge planted with peepal and banyan unsuited to its dry ecology.
    4. Islands of protection: Policy praises coexistence of people and wildlife on paper. In practice it builds isolated, walled African-style reserves that keep animals apart from people.
    5. Overflow into farms: Animals thriving inside walls spill into villages and fields, as elephants show. So landscapes, not species, should be the unit of conservation.

    Challenges

    1. Partial line protection: Undergrounding only in critical habitat leaves birds exposed wherever they fly beyond it.
    2. Grasslands undervalued: Open grasslands are treated as unproductive land, so they are easily diverted to farms and solar parks.
    3. Small founder pool: A flock bred from few birds risks low genetic diversity and poor survival after release.
    4. Flagship bias: Declines in common birds draw little policy attention compared with flagship species.

    Way Forward

    1. Bird diverters: Power utilities should fit bird diverters (reflective markers that make wires visible) across the bustard’s wider range.
    2. Grassland reserves: Rajasthan should notify key grasslands as conservation reserves under the Wildlife (Protection) Act, 1972.
    3. Landscape plans: The Union Environment Ministry should plan conservation across protected areas, farmland and corridors, with village participation.
    4. Bird monitoring: Fund regular national surveys of common birds so declines are caught early.

    Conclusion

    India can now breed a near-extinct bird in captivity but has not secured the open landscapes it needs. Whether the bustard’s wider range is shielded from power lines and land conversion will show if conservation moves beyond showcase releases.

    Key numbers

    1. Bustard decline: 600 birds by 2000.
    2. Rajasthan count: 140 to 175 birds by the 2010s.
    3. Indian roller decline: about 30% in 12 years.

    Back2Basics: Great Indian Bustard

    1. Threat status: Listed as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.
    2. Legal cover: Protected under Schedule I of the Wildlife (Protection) Act, 1972 and listed in Appendix I of the Convention on International Trade in Endangered Species (CITES).
    3. State bird: It is the State bird of Rajasthan.
    4. Range: Most survivors live in Rajasthan’s Thar Desert, with a few in Gujarat, Maharashtra, Karnataka and Andhra Pradesh.

  • 2 captive-bred Great Indian Bustards released in national park

    Why in the News

    For the first time, Great Indian Bustards (GIBs) bred in captivity have been returned to the wild, as conservation moves from raising birds in enclosures to rewilding them. The Union Environment Minister and Wildlife Institute of India (WII) scientists released two males into Desert National Park, Jaisalmer, Rajasthan, under Project GIB. Only about 150 GIBs are left in the wild.

    What is Project GIB, and why breed the bird in captivity?

    1. What it is: Project GIB is a long-term recovery programme for the critically endangered GIB. It runs two conservation breeding centres in Jaisalmer, at Ramdevra and Sam.
    2. Why it began: The wild population kept falling, so the centres raise a founder population, a starter stock for rewilding. It works like a seed bank kept for replanting a forest.
    3. How breeding works: From 2019, eggs collected from the wild were incubated artificially and the chicks hand-reared. These hand-reared birds later mated in captivity.
    4. Habitat restoration: The Rajasthan forest department has fenced about 200 sq km of grassland enclosures inside the park. WII has tracked tagged birds remotely for years (telemetry), and this data identifies the enclosures as prime breeding habitat.
    5. The takeaway: Captive breeding matters only if the birds survive in the wild, which this first release begins to test.

    What has the release achieved?

    1. First rewilding: Two male birds were released at Sam, the first of 11 birds earmarked for release.
    2. Captive stock: The centres hold 98 captive-bred birds, about 86 of them kept for captive reproduction.
    3. Breeding output: Captive reproduction yields more live chicks each year, with 29 born in 2026 against 24 in 2025.
    4. Reintroduction protocols: The Ministry of Environment, Forest and Climate Change says the release will help develop and refine protocols for returning captive-bred birds to natural habitat.

    Why does the GIB matter beyond the species?

    1. Grassland conservation: The GIB depends on open grassland, so protecting it protects an ecosystem often treated as wasteland. The Minister also linked it to land degradation neutrality, a goal where restored land offsets newly degraded land.
    2. Migratory stopover: GIB habitat is a resting stop for birds on the Central Asian Flyway. This migratory corridor crosses 30 countries from North to South Asia, linking the Arctic and Indian Oceans.

    Challenges

    1. Power line collisions: GIBs have poor frontal vision and fly into overhead transmission lines. Eg. The Supreme Court has heard cases on undergrounding lines in GIB habitat since 2021.
    2. Untested survival: Hand-reared birds have not learned predator avoidance or foraging from wild parents, so post-release survival is unknown.
    3. Narrow genetic base: A tiny wild population limits the genetic diversity of the founder stock.
    4. Grassland diversion: Open grasslands are converted to farming and renewable energy parks. Eg. Solar and wind projects in the Thar.

    Way Forward

    1. Post-release tracking: WII should tag every released bird and publish survival data before scaling up releases.
    2. Line mitigation: Power utilities should underground lines or fit bird diverters in priority GIB habitat.
    3. Grassland recognition: Rajasthan should record grasslands as ecosystems, not wasteland, in land records.
    4. Phased releases: Release the remaining earmarked birds in stages, adjusting protocols after each cohort.

    Conclusion

    Project GIB has moved from breeding numbers to the harder test of survival in the wild. Whether the released males survive, settle in the fenced enclosures and pair with wild birds is the metric to watch.

    Back2Basics: Great Indian Bustard

    1. Protection status: Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List and listed in Schedule I of the Wild Life (Protection) Act, 1972.
    2. Identity: One of the heaviest flying birds, known locally as Godawan, and the State bird of Rajasthan.
    3. Habitat: Dry grasslands and scrub, with the largest population in Rajasthan, mainly in Desert National Park.
    4. Threats: Overhead power lines, windmills, noise and changes in landscape and cultivation.

  • Rescue act

    Why in the News

    Tiger conservation in West Bengal has shifted from protecting a resident population to rebuilding one from nothing, as a royal Bengal tigress caught in Bihar becomes the first tiger reintroduced in the State, in Buxa Tiger Reserve. The step has been called “a triumph of bureaucracy, not ecology”, because the State acted only after its tigers had vanished.

    What is the Buxa reintroduction programme?

    1. What it is: Reintroduction means moving animals from a healthy population into a habitat that has lost them, much like restocking an empty shelf.
    2. Why it began: The National Tiger Conservation Authority (NTCA) found no tigers in the Buxa, Dampa and Palamau reserves by 2018. It proposed a programme with the Bengal Forest Department and the Wildlife Institute of India.
    3. Scale of the plan: The tigress is the first of seven tigers to be relocated to Buxa over two years.
    4. Habitat preparation: Since 2018 the partners have reintroduced chital (spotted deer), opened some forest canopy to revive grasslands, and moved villagers out of the reserve’s core to cut human wildlife conflict.
    5. The takeaway: Bringing tigers back is technically possible, but it does not by itself remove the pressures that emptied the reserve.

    Why did Buxa lose its tigers?

    1. Human settlement: Buxa is dotted with settlements and ringed by revenue villages and tea estates, which fragment the landscape, including migration corridors, the routes animals use to move between forests.
    2. Railway line: A railway line already threatens the region’s elephants, and the railways plan to restore a route to Jainti.
    3. Road traffic: Commercial traffic on the Bhutan to West Bengal road through Buxa disturbs the reserve.
    4. Closed canopy: Forests have grown into dense woodland with a closed canopy, which stifles grasses, so herbivore numbers dwindle.
    5. Prey collapse: Chital density is dismal, so goats, macaques and cattle now replace tigers’ preferred ungulates (hoofed prey).

    Is reintroduction conservation or rescue?

    1. Preventive model: From 1973 India followed preventive conservation, protecting source populations, the healthy groups that breed and supply tigers, with their habitats, prey and corridors.
    2. Reactive tradition: Buxa belongs to a newer, reactive tradition, alongside Sariska and Panna, where authorities intervened only after tiger populations crashed.
    3. Cost of rescue: Reintroduction showcases technical capability but is more expensive and more heavy handed than prevention.
    4. Inviolate core belief: Reintroduction follows Project Tiger’s belief that core habitat must be inviolate, meaning free of people. The state has used this to override the rights of Adivasis and forest dwellers and disrupt ecotourism incomes.

    What would success at Buxa look like?

    1. Transboundary corridor: Buxa is part of an international wildlife corridor contiguous with Phibsoo in Bhutan to the north and Manas in Assam to the east.
    2. Dispersal risk: If those forests offer more prey or less disturbance, released tigers may leave Buxa.
    3. Breeding test: Success means tigers establish territories and produce cubs that survive and breed, with natural immigration, tigers arriving on their own from nearby forests, keeping genetic diversity.
    4. Advance, not rescue: Success also means monitoring ecological deterioration so the state acts before tigers vanish, and involving local communities in decisions on conflict and livelihoods.

    Challenges

    1. Conflict after release: Tigers straying into tea estates and villages can turn local opinion against the programme. Eg. Tigress Avni was shot in Maharashtra in 2018.
    2. Poaching pressure: A small founder group can be wiped out quickly. Eg. Panna lost all its tigers by 2009.
    3. Rights conflicts: Relocation must be voluntary under the Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, so coercion invites legal challenge.

    Way Forward

    1. Prey before predators: The State Forest Department should raise chital density through grassland management before further releases.
    2. Rail mitigation: The railways should fix speed limits and build animal underpasses on forest stretches.
    3. Community dividend: Route ecotourism revenue to fringe villages through eco development committees.

    Conclusion

    Buxa’s first tigress restores a species but not yet the conditions that lost it. Whether tiger conservation moves from rescuing reserves after collapse to watching for decline early, with forest communities as partners, remains unresolved.

    Back2Basics: National Tiger Conservation Authority

    1. About: A statutory body under the Wild Life (Protection) Act, 1972, created through a 2006 amendment, under the Ministry of Environment, Forest and Climate Change.
    2. Chair and role: Chaired by the Union Environment Minister, it approves State tiger conservation plans and sets norms for tiger reserves.
    3. Project Tiger: It runs Project Tiger, which manages reserves through a core and buffer design.
    4. Tiger census: It conducts the All India Tiger Estimation every four years.

  • Centre to resume appraising post facto green clearance cases after top court ruling

    Why in the News

    Post facto environmental clearance proposals that were stalled, rejected, returned or de-listed because of the Supreme Court’s interim orders will now be processed again to a logical conclusion. The Ministry of Environment, Forest and Climate Change (MoEFCC) issued the direction to implement the Supreme Court’s judgment in Vanashakti v. Union of India (2026).

    What is post facto clearance, and why was it introduced?

    1. What it is: A post facto environmental clearance (EC) is approval given after a project began work, expanded or modernised without the legally required prior clearance, like a building permit sought after the house is built.
    2. The 2017 amnesty: The Centre first offered it in 2017 as an amnesty, a one time six month window for “violations” cases, projects that had started without clearance under the Environment Impact Assessment (EIA) Notification, 2006.
    3. Stated purpose: The aim was to limit damage from such projects by bringing them under environmental impact scrutiny.
    4. The 2021 Office Memorandum: In 2021 the Ministry issued an Office Memorandum (OM), an executive instruction, laying down a standard operating procedure for violations cases, so the one time window became a continuing route.
    5. The takeaway: A route meant to close past violations became a standing way to regularise them, which is why it reached the Supreme Court.

    How did the legal challenge unfold?

    1. Petitions against the regime: Petitions, including one by the Mumbai based non profit Vanashakti, challenged this after the fact clearance route. Several developers had already benefited, but many proposals stayed stuck.
    2. Stay in 2021: The Supreme Court stayed, meaning paused, the 2021 OM in the same year it was issued.
    3. Quashed in May 2025: The Court then struck down the entire mechanism, calling it illegal.
    4. Review and recall: On a review petition by the Confederation of Real Estate Developers’ Associations of India (CREDAI), the Court recalled, meaning withdrew, its May 2025 order and heard the matter afresh.

    What did the Vanashakti judgment hold?

    1. The Bench: Chief Justice of India Surya Kant and Justices Joymala Bagchi and Vipul M Pancholi ruled on July 29, 2026.
    2. 2021 OM quashed: The Court struck down the 2021 OM that had made violations cases a routine procedure.
    3. Past approvals protected: Post facto approvals already granted remain valid. Applications pending under the mechanism must be taken to their logical conclusion in accordance with law.
    4. Prior clearance mandatory: The prior clearance regime under the 2006 Notification is mandatory unless amended.
    5. 2017 window upheld: The Court upheld the 2017 notification because it was narrowly tailored and time bound.

    What has the Ministry now ordered?

    1. Bodies directed: On September 30, two months after the ruling, the Ministry told the project appraisal bodies to resume processing: Expert Appraisal Committees (EACs) at the Centre, State Environment Impact Assessment Authorities (SEIAAs) and pollution control boards.
    2. No fresh proposals: The direction carries a caveat that no fresh proposal will be accepted, so the route is closed to new violators.

    Challenges

    1. Rewarding violation: Clearing projects after construction weakens the incentive to seek approval first. Eg. Alembic Pharmaceuticals v. Rohit Prajapati (2020) rejected ex post facto clearance.
    2. No baseline left: Appraisal needs a site’s original condition, which construction has already erased.
    3. Thin appraisal capacity: Lapsed or non functional SEIAAs already stall routine clearances, and the revived backlog adds load.

    Way Forward

    1. Damage recovery first: Appraisal bodies should levy the cost of environmental damage under the polluter pays principle before granting any clearance.
    2. Change only by amendment: Any standing violations route should come only through an amended EIA Notification after public consultation.
    3. Deadline for the backlog: MoEFCC should fix a date by which every pending case is decided.

    Conclusion

    The Ministry has reopened only the pipeline of pending violation cases. No date is set for disposing of these cases, and whether the Centre amends the Notification to create a permanent violations route is the next thing to watch.

    Back2Basics: EIA Notification, 2006

    1. About: EIA predicts and seeks to mitigate a project’s environmental effects before approval. It became statutory under the Environment (Protection) Act, 1986, and was consolidated in 2006.
    2. Category A projects: These are appraised centrally by the MoEFCC through an EAC.
    3. Category B projects: These are appraised by the SEIAA with a State Expert Appraisal Committee (SEAC). Category B1 needs a full EIA study and public hearing; B2 is exempt from both.

  • Rising sea level threat to India’s eroding coastline

    Why in the News

    India’s coastal no-build strip is still measured from today’s high-tide line, even as the shoreline retreats and the sea rises faster. The UN General Assembly (UNGA) has adopted its first ever declaration on rising sea levels, asking nations to build sea-level rise projections into coastal infrastructure planning.

    What does the UN declaration settle about statehood?

    1. Montevideo test: The 1933 Montevideo Convention defines a State by a permanent population, defined territory, government and capacity to enter into relations with other states. A sinking country risks failing the territory test.
    2. Continued statehood: The declaration’s “presumption in favour of continued statehood” lets a sinking country keep its sovereignty, UN seat and nautical boundaries. It works like a title deed that survives the flood.
    3. Displaced people: Countries must protect the human rights of those who lose homes. Eg. Over a third of Tuvalu‘s 11,000 people have sought Australian climate visas.
    4. The takeaway: Sinking island nations such as Tuvalu, Kiribati and the Maldives keep their legal existence.

    What does India gain from a pledge meant for small islands?

    1. India’s stand: India backed stable maritime zones and reaffirmed “common but differentiated responsibilities and respective capabilities”: those who caused more warming and can pay more should do more.
    2. Island count: A 2023-24 remeasurement counts 1,298 offshore islands and islets.
    3. Island boundaries: Lakshadweep and the Andaman and Nicobar Islands push India’s sea boundaries into the Arabian Sea and Bay of Bengal, so fixed boundaries protect India too.

    Is India’s coastal law ready for a retreating shore?

    1. Eroding shoreline: The National Centre for Coastal Research (NCCR) found about a third of the mainland shoreline eroding.
    2. CRZ no-build strip: The Coastal Regulation Zone (CRZ) Notification, 2019 bars new building within 50 metres of the high-tide line in dense rural areas and 200 metres elsewhere.
    3. Moving baseline: The high-tide line marks today’s highest spring tide, so on the fastest-eroding stretches a house at the 50-metre edge reaches the water in about ten years.
    4. Unused hazard line: The Survey of India‘s hazard line factors in sea level rise, but the 2019 rules use it only for disaster management and land-use planning.

    Where does India fall short on people already displaced?

    1. Vanishing islands: In the Sundarbans, Ghoramara island has lost about half its area in five decades.
    2. Repeat displacement: Families who moved to Ghoramara from the vanished Lohachara island were displaced again within a decade, without secure tenure or livelihoods.
    3. No legal category: Indian law does not recognise people who lose land gradually to erosion, so each relocation is decided case by case.
    4. People at risk: A Frontiers in Marine Science review puts 45 million Indians at risk by 2050.
    5. Fiji’s model: Fiji wrote relocation into its Climate Change Act in 2021, backed by a trust fund.

    Challenges

    1. Locked-in rise: A UN brief finds seas will keep rising for centuries to millennia even at net zero.
    2. Adaptation finance gap: Developing countries’ adaptation needs far exceed the international public finance available.
    3. Distant finance goal: At the Baku summit, India called the new goal of $300 billion a year by 2035 “too little and too distant”.

    Way Forward

    1. Hazard-line baseline: Measure the no-build strip from the hazard line, or widen it by local erosion rates before the UN review due by September 2030.
    2. Erosion displacement law: Give families displaced by erosion land title and livelihood support by law.
    3. Finance diplomacy: Press for “timely and predictable disbursement” of adaptation finance at COP31 in Antalya in November.

    Conclusion

    The UN has secured sinking States’ legal future, but India’s coastal rules still plan against a shoreline moving inland. Whether the no-build strip moves to the hazard line before the next UN review will test India’s readiness.

    Key numbers

    1. Sea-level rise rate (World Meteorological Organization): 2.1 mm a year in 1993-2002, 4.7 mm in 2015-2024; a record 6 mm in 2024 alone.
    2. Rise by 2100 (‘Surging Seas in a Warming World’, 2024): about 38 cm at lowest emissions, about 77 cm if emissions keep climbing.
    3. Erosion (NCCR, 1990-2016): 234 sq km lost, 231 sq km gained; nearly 400 km retreating over 5 metres a year and 225 km by 3 to 5 metres; over 170 km of West Bengal in the fastest category.
    4. Adaptation finance (UN Environment Programme): needs over $310 billion a year by 2035; $26 billion of international public finance in 2023.
    5. India’s coastline (2023-24 remeasurement): 11,098 km.
    6. Ghoramara island area (Sundarbans): about 7.2 sq km shrinking to 3.6 sq km.

  • New efficiency norms: What will change for OEMs, small cars & SUVs

    Why in the News

    India’s car efficiency rules have moved from a proposed extra 3 g/km allowance for petrol cars weighing up to 909 kg to a single fleet-wide formula in which vehicle weight sets every carmaker’s target. The final Corporate Average Fuel Economy (CAFE)-III framework, notified on 29 September, also gives electric vehicles the biggest compliance benefit.

    What are the CAFE-III norms?

    1. What they are: CAFE norms cap the average fuel consumption across all cars a company sells, not each model, like a class average rather than each student’s score.
    2. Coverage: They apply to M1 category passenger vehicles, cars seating up to eight passengers besides the driver, manufactured or imported for sale in India.
    3. Period: The norms run for five financial years, from April 2027 to March 2032.
    4. Weight-based target: A maker’s permitted fuel consumption depends on the weighted average unladen weight (sales-weighted empty weight) of its vehicles. A heavier, SUV-led fleet gets a higher limit than a small-car fleet.
    5. The takeaway: Carmakers must now manage the efficiency of their entire portfolio rather than individual models.

    Why did the small-car concession go?

    1. Contested carve-out: Small cars became one of the most contentious points in drafting, since India’s market depends on compact, light petrol cars. A September 2025 draft proposed the extra allowance.
    2. Market concentration: Maruti Suzuki has an outsized presence in small cars. Rival carmakers argued the carve-out would disproportionately benefit a segment dominated by the largest carmaker.
    3. Changed weight formula: The reference weight, the baseline from which each fleet’s target is adjusted, rose from 1,170 kg in earlier versions to 1,229 kg. The weight adjustment is also flatter.
    4. No separate category: The final framework creates no separate category for the lightest cars. Their weight advantage is built into the broader fleet formula instead.

    What routes to compliance do carmakers get, and how has industry responded?

    1. Electric vehicle credit: Battery-electric and range-extended electric vehicles get a volume derogation factor of 3, so each counts as three vehicles when fleet performance is calculated.
    2. Carbon Neutrality Factor: This credit rewards makers for ethanol-blended petrol, biofuels and compressed biogas (CBG). It gives a route to compliance beyond efficiency gains and electrification.
    3. Industry welcome: Maruti Suzuki called it a comprehensive regulation built on scientific data and inter-ministerial consultation, recognising multiple powertrains and fuels.
    4. Predictable roadmap: Hyundai Motor India said the 3+2 year compliance block structure allows long-term product and technology planning.

    Challenges

    1. Diluted real gains: Counting each electric vehicle three times lets a maker sell more fuel-hungry cars and still meet its average.
    2. Fuel credit verification: Credits for ethanol and CBG assume cleaner fuel is actually used, which carmakers do not control.
    3. Lab versus road gap: Fuel consumption is certified on test cycles, which often understate real-world use.
    4. Softer SUV targets: A weight-based formula gives heavier fleets a higher allowance, so a shift to SUVs eases the target.

    Way Forward

    1. Taper the multiplier: The Ministry of Power should lower the derogation factor as electric vehicle sales rise.
    2. On-road checks: Testing agencies should add real-world fuel checks to certification.
    3. Public compliance data: The Ministry of Power should publish each carmaker’s fleet performance every year.
    4. Audited fuel credits: Carbon Neutrality Factor credits should be tied to verified fuel supply data from oil marketing companies.

    Conclusion

    CAFE-III ties every carmaker’s target to the weight of what it sells, which removed the case for a separate small-car carve-out. The first compliance block will show whether electric vehicle and clean fuel credits cut real fuel use or only soften the average.

  • SC rules out total ban on firecrackers for Deepavali

    Why in the News

    Firecracker policy for Deepavali has moved from the prospect of a total nationwide ban to a “limited and conditional relaxation” that permits next-generation joined green crackers. A Supreme Court Bench headed by Justice M.M. Sundresh ruled out the total ban, accepting suggestions from the Council of Scientific and Industrial Research-National Environmental Engineering Research Institute (CSIR-NEERI).

    What are next-generation joined green crackers?

    1. What they are: Joined crackers are a string of crackers linked to burst one after another. Green crackers are reformulated to pollute less, like a low-emission version of a regular product.
    2. Barium-free design: The green series is made without barium, a toxic chemical used for colour. Its shell or tube size, formulation, bursting duration and frequency also differ.
    3. Lower emissions: Tests show a 30% reduction in emissions compared with conventional joined crackers, with lower noise and fewer particulate emissions, the fine dust that enters the lungs.
    4. Less waste, longer bursts: Smaller shells cut solid waste generation by 4% up to 32%. The bursting time has increased five times.
    5. The takeaway: Cleaner chemistry lets the court allow festive crackers without accepting the full pollution load of conventional ones.

    What conditions has the court accepted?

    1. Compliance first: The court backed manufacture of these crackers only in compliance with applicable noise, emission and safety requirements.
    2. Approved formulations: As the Centre proposed, the crackers must conform to formulations tested and approved by the competent authority.
    3. Licensed makers only: The crackers must be made exclusively by duly licensed manufacturers.
    4. Noise and emission limits: They must stay within permissible emission levels and a noise limit of 125 dB(AI) or 145 dB(C) peak. These are decibel measures of sudden and peak loudness.
    5. Fixed design, no banned chemicals: CSIR-NEERI has prescribed the shell size, shell number and bursting duration. The crackers must be free of banned chemical ingredients.

    How will the court balance festive sentiment and clean air?

    1. Balanced view: The court said it would take a balanced view, given fears of air pollution with the onset of winter and the festive season.
    2. No total ban: The Bench remarked orally that a total ban “will hurt certain sentiments“.
    3. No round-the-clock bursting: It will not allow 24-hour bursting anywhere, as this affects the sick, the elderly and children. It will look into directing specific time windows for bursting.
    4. Further tests: The court gave the Central Pollution Control Board (CPCB) and the Union government more time for further barium and joined cracker decibel tests.

    Challenges

    1. Fake green labels: Conventional crackers sold as green are hard to tell apart at retail, so enforcement depends on market checks.
    2. Policing time windows: Bursting hours are hard to enforce across dense neighbourhoods on a single festival night.
    3. Seasonal pollution load: Crackers add to a season when stubble burning and still winter air already trap pollutants over north India.
    4. Livelihood pressure: Cracker production clustered around Sivakasi in Tamil Nadu employs many workers, so strict curbs hit jobs.
    5. Incomplete evidence: The relaxation comes before the pending barium and decibel tests are complete.

    Way Forward

    1. Verifiable packs: Approved crackers should carry QR codes that buyers and police can check against the CSIR-NEERI list.
    2. Uniform hours: The court should fix uniform bursting hours, enforced by local police.
    3. Live monitoring: The CPCB should publish noise and air quality readings through the festival.
    4. Industry transition: States should help cracker units shift to approved formulations through training and credit.

    Conclusion

    The Supreme Court has chosen regulated celebration over prohibition, resting that choice on cleaner cracker chemistry. Watch for its directions on bursting time windows and the results of the pending tests before Deepavali.

    Back2Basics: CSIR-NEERI

    1. Parent body: A laboratory of the Council of Scientific and Industrial Research, India’s largest public research network, under the Ministry of Science and Technology.
    2. Location: Headquartered in Nagpur, Maharashtra.
    3. Mandate: Research in environmental science and engineering, including air and water pollution control.
    4. Green crackers: It developed India’s first green cracker formulations after the Supreme Court’s 2018 order allowing only less-polluting crackers.

  • To save tigers, follow crime beyond the reserve

    Why in the News

    An assessment by TRAFFIC, a global non-profit that monitors trade in wild animals and plants, documents 2,551 seizures involving at least 3,808 tigers over 25 years to June 2025. Conservation has moved from isolated reserves to connected landscapes, but wildlife crime management has not made the same transition.

    Why is the tiger reserve no longer the frontline of protection?

    1. Two landscapes: A tiger’s ecological landscape runs from the protected area (PA) through buffers and corridors to human settlements. Traffickers work in an overlapping crime landscape, from poacher to collector, transit, market and consumer.
    2. Tigers on the move: Tigers cross buffers, corridors, plantations, farms, riverine strips and town edges, which leads to human-tiger conflict.
    3. Source, not boundary: The reserve remains the biological source, like a nursery. A tiger safe inside it becomes vulnerable in poorly monitored corridors.
    4. Information for criminals: Tigers moving repeatedly through poorly watched areas show poachers where to find them, so PA boundaries cannot remain the only line of protection.
    5. The takeaway: Tigers now live and die across a landscape that the reserve system was never designed to guard.

    How has tiger trafficking changed?

    1. Old geography of crime: Crime once meant poachers breaching a reserve and traders waiting outside, so protection meant patrolling, intelligence and intrusion detection. These remain indispensable.
    2. New products: Trafficking has moved from skin and bone to whole animals, dead and alive, and a wider range of derivatives.
    3. Linked networks: Tiger traffickers often share networks with the trade in leopard, bear and pangolin parts.
    4. New channels: Criminals use digital platforms, transport systems, financial channels and intermediaries far beyond traditional wildlife traders.

    What is a Tiger Crime Opportunity Surface, and who should act on it?

    1. Layered map: A “Tiger Crime Opportunity Surface” overlays young tigers’ dispersal routes, farm crossings, conflict villages, past offences and transport nodes. It shows where vulnerability and criminal opportunity meet.
    2. Act before mortality: The aim is to act before a tiger dies rather than investigate afterwards.
    3. Graded response: The same camera trap alert would trigger different action by zone: routine monitoring inside a PA, community preparedness in a conflict area, or extra patrols and intelligence gathering.
    4. Protection by zone: Inside the reserve, protection stays intensive and tiger specific. Beyond it, forest guards cannot carry the load alone.
    5. Inclusive enforcement: Protection should be intelligence-led, involving territorial forest staff, local communities, police, enforcement agencies and cyber or financial crime experts.

    Why do arrests not end tiger trafficking?

    1. Seizures without disruption: Isolated seizures and arrests rarely dismantle the systems that produce the crime.
    2. Missing kingpins: Cases usually target low and mid-level actors. Organisers and financiers are rarely booked.
    3. Follow the money: Cases must continue beyond arrest into financial investigation and network disruption.

    Challenges

    1. Thin territorial staff: Territorial forest divisions, where dispersing tigers roam, have fewer trained wildlife staff than reserves.
    2. Online trade: Wildlife products are sold through social media and messaging apps, beyond a forest guard’s reach.
    3. Weak financial probes: Wildlife cases rarely involve money-laundering investigators, so financiers escape.
    4. Community distrust: Villages losing crops and cattle to tigers may withhold information from forest staff.

    Way Forward

    1. Landscape crime maps: The National Tiger Conservation Authority (NTCA) should require every tiger landscape to build and update an opportunity surface.
    2. Joint task forces: States should form forest, police and cyber units for corridors and transport hubs.
    3. Financial tracing: The Wildlife Crime Control Bureau (WCCB) should work with financial intelligence agencies to trace traffickers’ money.
    4. Prompt compensation: States should pay quickly for tiger damage to keep communities on the side of protection.

    Conclusion

    Tiger conservation now plans for connected landscapes, but crime control is still organised around reserve boundaries and low-level arrests. The test is whether forest, police and financial agencies begin to share one intelligence system across each tiger landscape.

    Government Initiatives for Tiger Conservation

    1. Project Tiger (1973): Manages tiger reserves on a core-buffer model to reduce habitat pressure and human-tiger contact.
    2. Tigers Outside Tiger Reserves (TOTR): Uses artificial intelligence, GPS and camera surveillance to manage conflict involving about 30 per cent of tigers that live outside reserves.
    3. Wild Life (Protection) Amendment Act, 2006: Created the NTCA and the WCCB, and requires tiger conservation plans to protect corridors linking reserves.
