  • 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.

  • Delhi announces vehicle curbs, construction bans, 50% WFH to tackle winter pollution

    Why in the News

    Delhi’s winter pollution response has moved from curbs imposed after the air turns severe to a permanent, pre-announced action plan for the whole season. A meeting chaired by the Union Environment Minister with the Delhi Chief Minister and the Commission for Air Quality Management (CAQM) fixed curbs on vehicles, offices, construction and industry in advance of the annual winter spike.

    What is the winter action plan?

    1. What it is: A fixed, season-long set of pollution curbs announced before winter, like a timetable rather than an alarm sounded only after the air turns toxic.
    2. Why it is needed: As the southwest monsoon withdraws, cooler and stiller air traps dust and exhaust near the ground, so the National Capital Region (NCR) sees a sharp rise in pollution.
    3. Implementing bodies: The Union Environment Ministry, the Delhi Government and CAQM, the NCR’s statutory air quality body, run the plan together.
    4. Airshed approach: Delhi will coordinate action with NCR cities as one airshed, meaning the shared body of air a region breathes, because pollution crosses city limits.
    5. The takeaway: Pollution control becomes a standing seasonal routine, not a scramble after air quality turns severe.

    How will vehicles be curbed?

    1. Entry restriction: From 1 November to 31 January, vehicles registered outside Delhi that do not meet BS-VI (Bharat Stage VI, the strictest national emission standard) will be kept out.
    2. No PUCC, No Fuel: Vehicles without a valid Pollution Under Control Certificate (PUCC) will be denied fuel at all 500 fuel stations. Automatic Number Plate Recognition cameras will check each vehicle.
    3. End-of-life vehicles: Petrol vehicles older than 15 years and diesel vehicles older than 10 years will not be given fuel.
    4. Early campaign: A special awareness and enforcement drive at petrol pumps begins on 1 October.
    5. Parking charges: Charges at authorised parking sites will double, except at facilities of the Delhi Metro Rail Corporation.

    What changes for offices and construction?

    1. Work from home: Government and private offices must keep 50% of their staff working from home during the season.
    2. Staggered timings: Municipal Corporation of Delhi and Delhi Government offices will keep different hours, spreading rush hour traffic.
    3. Full construction ban: All construction and demolition stops from 10 December to 20 January, the peak smog window.
    4. Season-long dust curbs: Dust-generating demolition and outdoor civil construction are prohibited for the whole restriction period.
    5. Deadlines for works: Cement-concrete works are to finish by 31 October and bitumen (road tarring) works by 15 November.

    How will enforcement and monitoring work?

    1. Industrial crackdown: An artificial intelligence (AI) enabled command-and-control centre will drive enforcement against polluting industries. Of 11,271 units surveyed, 2,283 have already been closed or sealed.
    2. Monitoring network: Continuous air quality monitoring stations will rise from 47 to 60, mapping pollution sources more finely.
    3. Field enforcement: 334 enforcement teams will act on local sources, backed by weekly inspections of pollution hotspots.
    4. Citizen participation: Residents can report pollution and use a new citizen suggestions portal. Daily evening Air Quality Index (AQI) bulletins will inform the public.

    Challenges

    1. Pollution from outside: Delhi’s rules cannot reach farm fires and industry in neighbouring States. Eg. Stubble burning in Punjab and Haryana.
    2. Fuel-ban leakage: Vehicles refused fuel in Delhi can refill at pumps in NCR towns just across the border.
    3. Workers’ livelihoods: A six-week halt on building work cuts off daily wages for construction labourers.

    Way Forward

    1. Airshed-wide rules: CAQM should extend the same vehicle and fuel rules to NCR towns in Haryana, Uttar Pradesh and Rajasthan.
    2. Wage support: The Delhi Government should pay registered construction workers during the ban from the construction workers’ welfare cess fund, a levy collected on building work for workers’ welfare.
    3. Shared plate data: Link number plate recognition data across NCR fuel stations, so a refused vehicle cannot refuel next door.

    Conclusion

    Delhi has turned its winter response into a pre-announced, season-long regime rather than a reaction to smog. Its real test is whether NCR neighbours adopt matching rules, since the airshed does not stop at Delhi’s border.

    Back2Basics: Commission for Air Quality Management (CAQM)

    1. Legal basis: A statutory body under the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021, first set up by ordinance in 2020.
    2. Replaced EPCA: It replaced the Supreme Court-mandated Environment Pollution (Prevention and Control) Authority (EPCA), set up in 1998.
    3. Jurisdiction: The NCR and adjoining areas of Punjab, Haryana, Rajasthan and Uttar Pradesh.
    4. Powers: It issues binding directions on air pollution and enforces the Graded Response Action Plan (GRAP), the stage-wise curbs tied to AQI levels.

  • UN Sea Level Declaration

    Why in the News

    A country’s legal existence no longer depends on its coastline: under the Declaration on Sea Level Rise, low lying states threatened by rising seas keep their statehood and maritime zones even if their coasts retreat inland. The United Nations General Assembly (UNGA) adopted the Declaration by consensus.

    What does the Declaration protect?

    1. What it is: The Declaration is a political statement by all UN members on responding to rising seas, like a guarantee that a country’s legal existence outlasts its shoreline.
    2. Statehood preserved: Low lying countries such as Fiji, Tuvalu and Vanuatu keep their statehood, sovereign rights and UN membership.
    3. Maritime zones fixed: Sea zones under the UN Convention on the Law of the Sea (UNCLOS) are measured from the coast. The Declaration keeps them defined even as coasts retreat, so a shrinking shoreline does not shrink a country’s sea.
    4. Citizens’ rights: If the sea swallows a country’s territory, its citizens still keep their nationality and economic rights.
    5. The takeaway: A state can now lose its land without losing its legal existence, its seas or its people’s citizenship.

    How does the Declaration organise action?

    1. Origin: A 2024 high-level meeting gave members a mandate to negotiate an action oriented agreement. This Declaration is the result.
    2. Four areas of action: The four page text groups action under four heads:
      • science and data;
      • adaptation and financing;
      • livelihoods, socio-economic development, data sharing and early warnings;
      • the legal consequences of sea-level rise.
    3. People centred response: It asks countries to respond in ways that protect livelihoods and cultural heritage, involving affected communities.
    4. Continued engagement: Members commit to keep engaging on the issue, including a high-level meeting before the 84th session of the General Assembly ends.

    Why do island states need these assurances?

    1. Existential threat: Rising seas threaten to swallow most or all of the habitable territory of low lying island states in the coming decades.
    2. Collective voice: These states negotiate together as the Alliance of Small Island States (AOSIS) in forums including the Conference of the Parties (COP), the annual UN climate summit.
    3. Pace of rise: Global mean sea level is currently rising by about 4 to 5 mm a year.

    Challenges

    1. Not binding: A General Assembly declaration is a political commitment, not a treaty, so it creates no enforceable obligation.
    2. Legal survival is not physical survival: Retained statehood does not stop the flooding and salt intrusion that make atolls uninhabitable.
    3. Adaptation finance gap: Small islands cannot fund sea walls, raised land or relocation from their own budgets.
    4. Narrow migration routes: Pathways for displaced islanders remain small and bilateral. Eg. The Australia-Tuvalu Falepili Union treaty (2023).

    Way Forward

    1. Codify in law: The International Law Commission should carry its work on sea-level rise into a binding instrument on statehood and maritime zones.
    2. Deposit baselines now: Island states should deposit their baseline coordinates with the UN Secretary-General, so their zones stay fixed as coasts move.
    3. Grant based adaptation finance: Channel grants to small island states through the Fund for Responding to Loss and Damage.
    4. Early warning coverage: Extend the UN Early Warnings for All initiative to every low lying coast.
    5. India’s island partnerships: India should use the Infrastructure for Resilient Island States initiative to back these measures.

    Conclusion

    The Declaration settles what happens in law to a drowning state, but leaves the physical and financial question unanswered. The next test is whether the follow up meeting converts political assurance into binding law and money for adaptation.

    Back2Basics: UN Convention on the Law of the Sea (UNCLOS)

    1. What it is: The treaty adopted in 1982, in force since 1994, that sets the rules for using the world’s oceans and their resources.
    2. Maritime zones: A coastal state’s territorial sea runs up to 12 nautical miles and its Exclusive Economic Zone (EEZ) up to 200 nautical miles.
    3. Institutions: It created the International Tribunal for the Law of the Sea and the International Seabed Authority.
    4. India: India ratified UNCLOS in 1995.

  • Zones of worry

    Why in the News

    The seventh draft notification for an Ecologically Sensitive Area (ESA) in the Kerala stretch of the Western Ghats proposes to bring 9,993.7 sq km across 131 villages under the regime. The Kerala government will reiterate a counter position confining the area to 8,590.69 sq km across 98 villages, excluding human habitations and agricultural land. The first draft, based on the report of the High Level Working Group, covered 123 revenue villages and was never finalised, and six further drafts have followed without settling the dispute. The window for filing objections to the seventh draft closed on 25 September. The disagreement is no longer about whether the Ghats need protection. It is about whether an ecologically sensitive line is drawn around ecology or around land use.

    What does the Ecologically Sensitive Area regime restrict?

    1. Purpose of the designation: Those framing the proposals state that the notification is intended to regulate activities that can damage fragile ecosystems, rather than to remove human presence from the landscape.
    2. What the draft prohibits: Mining, quarrying and sand mining are barred in the notified areas.
    3. What the draft leaves untouched: There are no restrictions on the repair, extension or renovation of existing residential houses, or on changes in ownership of land.
    4. The basis of the classification: The zonation rests on ecological sensitivity, the approach proposed by the Western Ghats Ecology Expert Panel.

    How far apart are the Centre’s draft and Kerala’s counter position?

    1. The area proposed: The seventh draft, issued on 27 July, covers 9,993.7 sq km across 131 villages in Kerala.
    2. The forest and non forest split: Of that area, 9,107 sq km is forest and 886.7 sq km is non forest.
    3. The State’s figure: Kerala will press for 8,590.69 sq km across 98 villages, with the ecologically sensitive areas confined to forests and leased forest plantations.
    4. The principle behind the State’s figure: Kerala argues that inhabited and cultivated landscapes should not be treated in the same manner as forests and other ecologically fragile areas. The demand reflects a position held by successive State governments across the political divide.

    Why do high range residents read the notification as a threat to their land?

    1. Origin of the settlements: The Grow More Food campaign of the erstwhile Travancore administration in the early 1940s encouraged migration into the high ranges. Families moved in to farm, and habitations turned large stretches of the mountains into agricultural landscapes.
    2. Damage done by uncertainty rather than by rules: After 2013 people began cutting down trees for fear they would not be able to use their land later. Farmlands were abandoned and land prices fell.
    3. Effects already visible: The Melukavu panchayat president in Kottayam says the issue has affected access to loans and land transactions, and has told on the marriage prospects of young people in the region.
    4. The ecological rationale questioned: The president of the Rubber Producers’ Society at Edamaruku in Kottayam points out that the nearest forests lie about 30 km to the north and about 50 km to the south of the village proposed for inclusion.
    5. The jurisdictional fear: The chairperson of the Kerala Independent Farmers Association argues that inclusion takes a holding out of the jurisdiction of the State Revenue department and places it with the Central regime, so residents would have to seek Central clearance for almost every activity. The proposal in that reading creates two categories of residents, those inside the ESAs and those outside.

    How did the Gadgil report and the Kasturirangan review set the terms of the dispute?

    1. The original proposal: The Western Ghats Ecology Expert Panel, chaired by Madhav Gadgil, proposed a comprehensive zonation of the Ghats based on ecological sensitivity.
    2. How it was received in the high ranges: The report generated fears that agriculture and development would be restricted, and that existing settlements could eventually face displacement.
    3. The review that followed: The Centre appointed a High Level Working Group chaired by K. Kasturirangan to review the Gadgil recommendations. Environmentalists hold that the group watered down the restrictions.
    4. The first draft and the stalemate after it: The first draft notification, based on the High Level Working Group report, proposed 123 revenue villages in Kerala, mainly in Idukki and Wayanad. Protests prevented a final notification and six more drafts followed.
    5. The State’s own committee: A committee appointed by the State government under Oommen V. Oommen recommended excluding inhabited areas, plantations and agricultural lands through physical verification and field surveys. It also proposed re fixing the ecologically sensitive areas using cadastral maps, which are plot level land records, approved by the Kerala State Biodiversity Board.

    What have conservationists and the panel’s own members said in reply?

    1. The fears called propaganda: The president of the Wayanad Prakruthi Samrakshana Samiti says apprehensions of restrictions on building houses and digging wells are baseless political propaganda pushed by vested interest groups.
    2. Existing law already protects forests: The same view holds that a host of laws, including the Forest Act and the Wild Life (Protection) Act, 1972, already protect forests, so classifying forest areas as ESAs adds nothing.
    3. What the Gadgil report asked for: A member of the panel states that the report recommended a shift to organic farming and never opposed farming. It opposed the pollution of water resources through chemical pesticides, called for non polluting industries, and placed no restrictions on local infrastructure development.
    4. Who was to decide: The panel’s approach was to give local communities a decisive role in determining how development should proceed in ecologically sensitive landscapes, in place of a blanket ban on local activity.
    5. The latest draft already concedes ground: The chairman of the State appointed committee notes that the current draft has excluded farmlands and plantations from the ESAs, which leaves the objection directed at fragile rocky land the high range communities do not own.

    How has the dispute reshaped mobilisation and politics in the high ranges?

    1. Idukki as the epicentre: Fifty one villages in Idukki figure in the latest draft, and all the grama sabhas there have passed resolutions urging the Union and State governments to exclude their villages from the regime.
    2. An organised church led agitation: The Idukki Diocese of the Syro Malabar Church has been at the forefront of the anti ESA agitation since 2013, and the High Range Samrakshana Samiti under its patronage has organised protests across the high ranges. The Church’s position is that human habitations and farmlands must be fully excluded.
    3. The electoral consequence: In the 2014 Lok Sabha election the Samiti’s legal adviser, standing as an Independent backed by the Left Democratic Front (LDF), won the Idukki seat, long considered a Congress citadel.
    4. The heritage listing drawn in: The State vice president of the All India Kisan Sabha, the farmers’ wing of the Communist Party of India, has demanded that the Western Ghats be removed from UNESCO World Heritage Site status, which requires more stringent conservation. The counter cited is that UNESCO guidelines themselves require exclusion of an area where a project disrupts the livelihood or daily life of the local population.

    Can protection and settlement be mapped on the same hills?

    1. The question conservationists are asking: For conservationists the central issue is whether human activity in the Western Ghats can continue without weakening ecological safeguards.
    2. The question residents are asking: For residents the distinction between forest and settlement is critical, because their houses, farms and livelihoods are embedded in the same landscape that conservation policy seeks to protect.
    3. The same hills read two ways: The same slopes are treated as a fragile ecological system requiring protection and as a lived landscape of farms, homes and communities built over generations. The disagreement has simmered through more than a decade of committees, consultations and draft notifications.

    Conclusion

    Seven drafts have narrowed the area and settled nothing. The Centre and the State are not arguing about protection; they are arguing about the unit the line is drawn on, and each successive draft has restated that disagreement rather than resolved it. With the objection window now shut, the decision point is whether the Centre finalises the notification on its own mapping or reopens the plot level verification the State’s committee asked for.

  • New cat in habitat, and some glimmer of hope

    Why in the News

    A new species of wild cat, Leopardus tilcayo, has been described in Bolivia, the first feline species identified in a hundred years. A new penguin species, also the first in a century, has been described on a group of subantarctic islands, and a new snake species has been described in New Guinea. A 2025 University of Arizona study records that 15 per cent of all known species were described in the last 20 years. The tension the item raises is that species are being found faster than ever at the same moment that loss of species dominates public attention, and that most of these discoveries reach no audience beyond the scientific and conservation communities.

    What has actually been described?

    1. A new wild cat: Leopardus tilcayo has been described in Bolivia. It is the first discovery of a feline species in a hundred years, which is why it drew the loudest response of the three.
    2. A new penguin: A new penguin species has been described on a group of subantarctic islands, and it too is the first in its group in a century.
    3. A new snake: A new snake species has been described in New Guinea and named after the guitarist Slash.
    4. What a description is: A species is described when a specimen is formally published with a diagnosis separating it from every named relative and a binomial name. Recognition of the animal by local communities usually long predates the formal description.

    Why is the rate of description rising?

    1. The measured pace: The 2025 University of Arizona study finds that 15 per cent of all known species were described in the last 20 years, so the quest to identify every species has accelerated rather than exhausted itself.
    2. Genetic tools separate look alike populations: DNA sequencing distinguishes populations that field observation had grouped as one species, which converts a known animal into two or more named ones.
    3. Survey effort has widened: Camera traps, acoustic recorders and systematic surveys in regions that were never surveyed intensively produce records that no expedition method previously returned.
    4. Museum collections are being re examined: Specimens collected decades ago and shelved without close study are now being sequenced, and some are found to belong to undescribed species.

    Why do most of these discoveries go unnoticed?

    1. The preference for the photogenic: Public and media attention follows animals that are visually appealing, which is why a wild cat and a penguin were reported and the invertebrate descriptions of the same period were not.
    2. Attention decides funding: Conservation money follows public interest, so charismatic vertebrates draw project funding while the taxa that carry most of the planet’s species diversity do not.
    3. The scale of what is unrecorded: Most described species are insects and other invertebrates, and the undescribed share of global diversity sits overwhelmingly in those groups rather than among mammals and birds.

    Challenges to protecting newly described species

    1. A name confers no protection: Formal description creates a scientific record, not a legal status, and assessment and listing are separate processes that follow it. Eg. An International Union for Conservation of Nature Red List assessment and a Convention on International Trade in Endangered Species listing are each decided after a species has been named.
      The Fix: Grant an interim protected status on description, lapsing once a formal assessment is completed.
    2. Publicity raises collection pressure: A newly named species with a small known range becomes a target for private collectors and the exotic pet trade, and the published description tells them where to look. Eg. Newly described reptiles and amphibians have appeared in the international pet trade shortly after their descriptions were published.
      The Fix: Withhold precise locality coordinates from published descriptions of small range species and release them only to designated authorities.
    3. Taxonomy has too few working specialists: The number of trained taxonomists able to describe a group has fallen while the backlog of collected specimens has grown. Eg. Specimens from tropical surveys routinely wait years in museum collections before anyone describes them.
      The Fix: Fund standing taxonomy positions tied to national collections and digitise specimen records so that identification is not gated on a single expert.
    4. Splitting one species into several shrinks each unit: When genetic work divides a widespread population into separate species, each resulting species holds a smaller range and a smaller population than the original did. Eg. A taxon once assessed as secure can yield two narrowly distributed species that each qualify as threatened.
      The Fix: Require a conservation reassessment of every resulting species immediately after a taxonomic split, rather than at the next scheduled review.
    5. Habitat is lost faster than it is surveyed: Land conversion in the regions that hold the most undescribed diversity removes populations before anyone records that they existed. Eg. Andean and New Guinean forests, where two of these three species were found, are under conversion and fragmentation pressure.
      The Fix: Protect habitat at the landscape level in high endemism regions rather than species by species after each description.

    Conclusion

    The rate of description and the rate of loss are both rising, and the two are not in tension, because a species can be named and lost within the same decade. What the description of a large mammal after a hundred year gap establishes is that the inventory is far from complete, which undercuts any assumption that conservation is working on a known list. The part that remains unaddressed is the gap between naming a species and protecting it, since nothing in the act of description obliges any state to do anything. What to watch is whether these three species receive conservation assessments and any protected status, and how quickly.
