  • Can AI claim copyright for original work? A question of authorship

    Can AI claim copyright for original work? A question of authorship

    Why in the News

    India’s Copyright Office has rejected an application seeking copyright registration for an artwork generated by an artificial intelligence (AI) system. The application was filed by American computer scientist Stephen Thaler for a work titled ‘A Recent Entrance to Paradise’, which he said had been generated autonomously by his AI system DABUS. The application named DABUS as the author and Thaler as the owner of the copyright. The order is among the first Indian decisions to address who, if anyone, is the author when an AI system generates a work. The tension it exposes is that the Office found the image original enough to qualify for protection while holding that the entity that produced it cannot be an author.

    What is DABUS?

    1. The system: DABUS stands for Device for the Autonomous Bootstrapping of Unified Sentience, an AI system developed by Thaler.
    2. The claim made for it: The application asserted that DABUS had generated the artwork autonomously, rather than as an output directed by a human operator.

    What did the application claim and what did the Office ask?

    1. The filing: Thaler applied in 2022 to register copyright in the artwork.
    2. The first question put to him: The Copyright Office asked whether an AI system could legally be recognised as an author under the Copyright Act, 1957.
    3. The second question: It also asked who should be treated as the author if the work was indeed generated using AI.
    4. The offer he refused: During the proceedings the Office allowed Thaler to amend the application and identify himself as the author. He declined, and continued to insist that DABUS be recognised instead.

    How does the Copyright Act, 1957 treat originality?

    1. The three separate questions: The Act answers whether a work is original, who its author is, and who owns the copyright, and these are distinct questions rather than one.
    2. The protection provision: Section 13 protects original literary, dramatic, musical and artistic works.
    3. The Act does not define originality: The Copyright Office therefore interprets it from Eastern Book Company v. D.B. Modak.
    4. The judicial test: The Supreme Court in that case held that a work need not be novel or groundbreaking to receive copyright protection. It must show at least a minimum degree of creativity, and it cannot be merely copied or mechanically reproduced.

    How does the Act treat authorship and ownership?

    1. The authorship provision: Section 2(d)(vi) identifies the author of a computer generated work as “the person who causes the work to be created”.
    2. The disputed phrase: The dispute was over whether that phrase refers to the machine producing the output or to the person creating and operating the system.
    3. First ownership: Section 17 states that the author is generally the first owner of the copyright.
    4. Transfer: Sections 18 and 19 allow copyright to be assigned or transferred through legally recognised agreements.
    5. What the structure assumes: The Office noted that these provisions are built around legal persons who can hold rights, transfer them and enforce them.

    What did the Copyright Office decide?

    1. Originality was satisfied: The Office found that the image generated by the AI was original enough to qualify for copyright protection.
    2. Authorship is a legal status: The Act treats authorship as a legal status carrying rights and responsibilities, and an AI system, however sophisticated, does not presently possess such recognition under Indian law.
    3. The tool test: To interpret who “causes” a computer generated work to be created, the Office looked to American copyright cases distinguishing between a tool and the person handling it.
    4. DABUS as the tool: Although DABUS generated the final image, it did so within a system designed and set in motion by Thaler, so DABUS was treated as the tool and Thaler as the person who legally caused the work to be created.
    5. Person means natural or juristic: Where an Act refers to a “person” it usually means a natural person or a juristic person such as a company, an entity capable of owning property and entering contracts. DABUS is not a recognised juristic person.
    6. The outcome: Thaler was held to be the person capable of being identified as the statutory author, so the application as filed did not meet the criteria under the Act.

    Why was the fallback request also rejected?

    1. What was sought: Thaler asked in the alternative that DABUS be recorded as the technological generator of the work.
    2. The register cannot confer status: The Office held that the register could not be used to indirectly confer legal status on an AI system.
    3. A procedural ground as well: No proper application seeking such an entry had been made.

    What has the order left open?

    1. A future application can succeed: The order leaves open the possibility of a fresh application that identifies the author in the manner the Copyright Act, 1957 requires.
    2. The change of law is reserved: Any broader change in the law would have to come from Parliament.
    3. The stated limit on administrative power: The order records that whether legal personhood or authorship should ever be extended to autonomous artificial intelligence “remains a policy decision strictly reserved for Parliament, and cannot be introduced via administrative reinterpretation”.

    Challenges to fitting AI generated works into copyright law

    1. Human contribution is not measurable at the point of registration: A registrar cannot tell from the output whether a prompt involved creative choice or a single instruction. Eg. The United States Copyright Office refused registration for the AI generated images in the comic ‘Zarya of the Dawn’ while protecting the human written text and arrangement.
      The Fix: Require a disclosure of AI involvement and of the specific human contribution as a mandatory field in the registration application.
    2. Training data use is unresolved: Models are trained on protected works without licence, so the lawfulness of the input sits behind every question about the output. Eg. Indian news publishers and a music industry body have sought to intervene in the Delhi High Court proceedings against OpenAI on this ground.
      The Fix: Legislate a statutory text and data mining exception with a transparency obligation on training corpora, so the boundary is set rather than litigated case by case.
    3. Ownership defaults to the operator rather than the investor: Treating the person who causes creation as the author leaves the platform, the model developer and the user with competing claims over the same output. Eg. Generative service terms typically assign output rights to the user by contract, which no statute confirms.
      The Fix: Make the allocation of rights in computer generated output a default statutory rule that contracts may vary, rather than leaving it to terms of service alone.
    4. Term of protection has no anchor without a human author: Copyright duration runs from the author’s lifetime, which cannot be computed where the generating entity does not die. Eg. The United Kingdom sets a fixed 50 year term for computer generated works precisely to avoid this problem.
      The Fix: Provide a fixed term measured from the date of creation for works with no identifiable human author.
    5. Enforcement needs an accountable person: Liability for infringing output, and standing to sue over it, both require someone the law can reach. Eg. An autonomously generated image that reproduces a protected character leaves no party with a stated duty under the current provision.
      The Fix: Attach statutory responsibility for infringing output to the person who deployed the system, mirroring the authorship rule the Office has applied.

    Conclusion

    The order settles who the author is and leaves untouched what the author did. A work the law accepts as original was produced by a process its named author did not perform, and the statute has no category for that gap. Parliament is the only body that can create one. The point to watch is whether computer generated works are taken up as a legislative question, or whether the issue keeps returning through individual registration applications and appeals against their refusal.

    Back2Basics

    1. Enactment: The Copyright Act, 1957 came into force in January 1958 and is India’s governing copyright statute.
    2. Administration: It is administered through the Copyright Office, which functions under the Department for Promotion of Industry and Internal Trade.
    3. Coverage: It protects literary, dramatic, musical and artistic works, along with cinematograph films and sound recordings.
    4. Registration is optional: Copyright arises on creation of the work, and registration serves as evidence rather than as the source of the right.

    [2014, GS3, 12 marks] In a globalised world, intellectual property rights assume significance and are a source of litigation. Broadly distinguish between the terms – copyrights, patents and trade secrets.”

  • River-linking is not the solution

    River-linking is not the solution

    Why in the News

    The Union Home Minister used the Southern Zonal Council meeting at Mamallapuram to press for early resolution of water sharing disputes in the southern region, and to propose linking major rivers from the Brahmaputra to the Godavari and the Cauvery.

    Why does the Pennaiyar case undercut the promise of early resolution?

    1. The grievance: Tamil Nadu is aggrieved over what it terms a violation of the 1892 inter State agreement by Karnataka.
    2. The request and the parallel litigation: Tamil Nadu asked the Centre in November 2019 to establish a tribunal. It also moved the Supreme Court with the same demand.
    3. Negotiation without settlement: Two negotiation committees have been formed since then and 11 meetings have been held.
    4. A court direction, then an extension: The Supreme Court in February directed the Centre to form the tribunal within a month, and later extended the deadline by six months. The adjudicatory body is still not in place.
    5. The referral suggestion: The Centre asked the court whether the Pennaiyar dispute could be referred to the Mahadayi Water Disputes Tribunal instead of constituting a new one, although there is nothing in common between the two disputes.
    6. The statute does not allow it: The Interstate River Water Disputes Act, 1956 does not permit such a referral.
    7. A second unanswered demand: The Central government has not replied to Tamil Nadu’s demand, made in March this year, for a tribunal on the Mekedatu dam project proposed by Karnataka.

    What are the objections to inter-linking?

    1. The proponents’ claim: Supporters of river linking, Tamil Nadu among them, hold that the intent is not to disturb the natural flow of any river but to divert a portion of surplus water.
    2. The claim on surplus is disputed: Many experts are not convinced, and expect that once linking is allowed, benefiting regions will demand water even in times of distress.
    3. The original beneficiary loses: That escalation would eventually deprive the original beneficiaries of their quota, which converts a transfer of surplus into a redistribution of entitlement.
    4. The ecological objection: Kerala has stoutly opposed the Pamba-Achankovil-Vaippar link proposal, on the ground that it will affect the Vembanad wetland system, into which the Pamba and Achankovil rivers drain.
    5. The agency’s answer: The National Water Development Agency, the central body that prepares feasibility studies for inter-basin transfer links, says it has accounted for improving the flow of rivers in lean periods.

    What is the record of inter-basin transfer in India?

    1. A thin record over 130 years: In the last 130 odd years the country has seen only a handful of inter-basin transfer projects, most of them in south India.
    2. The projects treated as successes: The Mullaperiyar dam, the Parambikulam-Aliyar project, the Krishna Water Supply Project and the Indira Gandhi Canal Project are regarded as successful examples of inter-basin transfer.
    3. An institution without output: A Special Committee for Interlinking of Rivers was formed after 2014 and has held over two dozen meetings, without much headway.
    4. The one project that moved: The foundation stone for the ₹44,000 crore Ken-Betwa Link Project was laid in 2024.
    5. Its social cost surfaced immediately: That project has led to agitations by tribal populations in Chhatarpur.

    Why is supply side expansion reaching its limit?

    1. Land is the binding constraint: Land is becoming scarcely available for projects of this size.
    2. Acquisition faces organised resistance: Resistance among people is growing when it comes to land acquisition.
    3. The consequence for project design: The days of implementing mega irrigation projects are almost over, which removes the delivery route the linking proposal depends on.

    What does demand side management require?

    1. A shift in the object of policy: Governments at the Centre and in the States, and civil society, need to focus on demand side management instead of perpetually seeking supply side interventions.
    2. Conservation as the priority: The priority has to be conserving what is available and using it judiciously.
    3. A programme aimed at the farmer: A massive programme of sensitising and incentivising farmers on the optimal use of water has to be launched.
    4. The subsidy that drives extraction: Indiscriminate extraction of groundwater, facilitated by free electricity for agriculture in many States, is paving the way for ecological disaster and has to be curbed immediately.

    Challenges to inter-basin water transfer proposals

    1. Surplus is asserted rather than measured: A basin is declared surplus on hydrological series that predate current withdrawal and cropping intensity, so the transferable volume is an estimate that has never been revalidated. Eg. Peninsular link proposals rest on assessments framed decades before present groundwater draft in the same basins.
      The Fix: Publish a revalidated basin water budget, with the assessment year stated, before any link component is taken up for investment approval.
    2. Himalayan links depend on flows that originate outside India: A transfer scheme drawing on the Brahmaputra is exposed to upstream storage decisions India has no treaty right to see. Eg. The Brahmaputra enters India as the Yarlung Tsangpo after a long course through Tibet.
      The Fix: Make a binding upstream flow data arrangement a stated precondition before any Himalayan component of a national grid is sanctioned.
    3. Transferred water carries a permanent energy bill: Peninsular links must lift water across watersheds, so the delivered cost includes pumping power for the life of the project. Eg. Moving water across the Eastern Ghats requires sustained lift rather than gravity flow.
      The Fix: Price transferred water at its delivered cost including pumping energy, so the recipient command area faces the real cost of the supply.
    4. Alignments run through forest and protected areas: Canal alignment and submergence take the least contested land, which in practice is forest and reserve land rather than settled farmland. Eg. The Ken-Betwa link submerges part of the Panna Tiger Reserve.
      The Fix: Require a no alternative alignment finding, tested against a published route comparison, before submergence inside a protected area is cleared.
    5. New supply changes cropping and returns the shortage: A command area that receives assured water shifts to water intensive crops, so demand rises to meet the new supply within a decade. Eg. Long canal commands in western India moved to paddy and sugarcane and developed waterlogging and salinity.
      The Fix: Tie the release of transferred water to a notified crop plan and volumetric delivery through water user associations rather than to area based supply.

    Conclusion

    India is being offered more supply while the reason for the shortage stays untouched. A grid that moves water between basins does not change how the water is used once it arrives. The immediate decision point is the Pennaiyar tribunal, still unconstituted after a court set deadline and an extension of it. Free farm power, and the groundwater extraction it underwrites, is the variable that will decide whether any new transfer capacity is absorbed or simply exhausted.

    Water Resources Management in India

    1. About: Water resources management covers the planning, development and management of water quantity and quality across every use, along with the institutions, infrastructure, incentives and information systems that guide it.
    2. The hydrological imbalance: India has an effective rainfall period of 28 to 29 days in a year, so most annual flow arrives in a short window and has to be stored or lost.
    3. Agriculture dominates demand: Agriculture accounts for around 89 per cent of groundwater extraction.
    4. The institutional home: The Ministry of Jal Shakti was formed in 2019 by integrating two earlier water related ministries.

    Constitutional Framework Governing Water Resources Management

    1. Entry 17, State List: Places water supply, irrigation, canals, drainage, embankments and storage with the States, subject to Entry 56.
    2. Entry 56, Union List: Allows Parliament to regulate inter State rivers and river valleys where it declares such regulation to be in the public interest.
    3. Article 262: Empowers Parliament to provide for adjudication of inter State river water disputes, and to bar the jurisdiction of the courts including the Supreme Court over them.

    Laws and Rules Governing Water Resources Management

    1. Interstate River Water Disputes Act, 1956: Provides for the constitution of a tribunal when a State’s request for adjudication cannot be settled by negotiation.
    2. The 2002 amendment: Fixed a one year limit for constituting a tribunal and a three year limit for the award.
    3. River Boards Act, 1956: Enables the Centre to set up river boards to advise on the regulation and development of an inter State river. No board has been constituted under it.
    4. Dam Safety Act, 2021: Establishes national and State level authorities for the surveillance, inspection and maintenance of specified dams.

    Government Initiatives for Water Resources Management

    1. Atal Bhujal Yojana: Launched in 2019 to improve groundwater management in selected States through community participation.
    2. Pradhan Mantri Krishi Sinchayee Yojana: Expands assured irrigation coverage and promotes micro irrigation under the Per Drop More Crop component.
    3. National Water Mission: Targets integrated water resource management and a 20 per cent improvement in water use efficiency, with the Bureau of Water Use Efficiency set up under it in 2022.

    Challenges in Water Resources Management

    1. Groundwater is extracted faster than it recharges: Assessment blocks in the north west and the south are classified as over exploited, which means annual draft exceeds annual recharge. Eg. Central Ground Water Board assessments place large parts of Punjab, Haryana and Rajasthan in that category.
      The Fix: Extend community level water budgeting with metered abstraction, so a village sees its own draft against its own recharge each season.
    2. Cropping patterns ignore local water availability: Crop choice follows assured procurement and price, not the water the region actually has. Eg. Sugarcane in Marathwada consumes a disproportionate share of a chronically drought affected region’s irrigation water.
      The Fix: Link procurement or price support for water intensive crops to verified micro irrigation adoption on the same holding.
    3. Irrigation charges recover a fraction of the cost: Water charged below the cost of delivering it removes any incentive to use less of it. Eg. Canal water rates in most States do not cover the operation and maintenance cost of the system supplying it.
      The Fix: Move to volumetric supply at the outlet, billed through water user associations rather than assessed on irrigated area.
    4. Basin data is incomplete and not shared: Allocation disputes are argued over rival estimates because no agreed real time record of flows exists. Eg. Rival State claims in southern river disputes rest on differing assessments of the same basin’s yield.
      The Fix: Make real time gauge and groundwater data on one national platform the sole admissible basis for allocation claims.

  • Fragile ecology, competing interests: The red flags in building Himalayan dams

    Fragile ecology, competing interests: The red flags in building Himalayan dams

    Why in the News

    A glacier collapse near the China Tibet border has triggered floods in Nepal that have killed over 1,100 people, with thousands still missing. The event has renewed expert concern about recent human made changes in a mountain system whose climatic conditions are shifting quickly. 13 hydropower plants, including several under construction projects, were affected.

    Why is the Himalayan system already fragile?

    1. A naturally unstable mountain system: The Himalayas are prone to earthquakes, landslides, avalanches and flash floods before any human intervention is added.
    2. The topography concentrates risk: The region carries lakes formed by melting glaciers, fast flowing rivers and steep slopes, in a zone highly vulnerable to strong earthquakes.
    3. Climate change acts on the pace of natural processes: Temperature change affects the pace and frequency of snow melting and thawing, and of glacial lake outburst floods (GLOFs), which occur when water collected from melting glaciers overflows its containing barrier.
    4. Attribution and risk are separate questions: Linking any single disaster directly to climate change still requires more scientific assessment, and the overall level of risk appears to be increasing.

    How does infrastructure build up compound the toll?

    1. Dams carry a genuine benefit: Dams and reservoirs regulate the flow of water and extend access to services for people living in remote regions.
    2. Construction alters the geology: Building a dam disturbs the geology of the area and makes it more prone to earthquakes, and the drilling and tunnelling required for further projects extends that effect.
    3. Damage runs through the assets themselves: The loss of hydropower plants in this flood dented both generation capacity and access to power.
    4. Exposure has risen with use: Infrastructure build up and high tourist footfall together compounded the disaster’s toll.

    How extensive is Himalayan hydropower now?

    1. Across the Tibetan region: One recent study identified at least 193 dams built or planned across the wider Tibetan region since 2000.
    2. In Nepal: A Nepal hydropower database lists more than 570 projects at different stages.
    3. The largest single project: China is building a massive dam on the Yarlung Tsangpo, the upper course of the Brahmaputra, near Arunachal Pradesh.
    4. A fault beneath it: In July, Chinese researchers flagged an active fault line, a fracture between two blocks of rock, directly beneath the Yarlung Tsangpo mega dam.

    Why is Himalayan dam building also a geopolitical contest?

    1. Infrastructure as a sovereignty marker: Chinese infrastructure building in Tibet is treated by China as a marker of sovereignty over Tibet, not only as an energy programme.
    2. The response is more dams: India, Nepal and Bhutan have responded with their own set of dams, and India is helping Bhutan build a series of hydropower projects.
    3. Signalling and counter signalling: The result is a pattern of signalling and counter signalling in which project decisions answer each other rather than answering the basin’s hydrology.

    What is missing in transboundary cooperation?

    1. No substantial ecosystem cooperation: There has been no substantial cooperation between China and Nepal, or between China and India, on managing the shared ecosystem.
    2. The existing mechanism is narrow: Disasters in the 2000s prompted a memorandum of understanding between India and China in 2002, with an expert level mechanism on transboundary rivers created in 2005. That mechanism has to be expanded to cover other aspects such as GLOFs.
    3. Transparency differs across the border: Nepal officially publishes fairly detailed project and licensing information. Chinese project level information exists but stays scattered across separate official documents and announcements rather than in a comparable consolidated public database.
    4. No real time upstream data: There is no clearly established public system between China and Nepal for continuous, real time sharing of upstream river flow, reservoir operations or glacial lake conditions from Tibet.
    5. Early warning fails at the border: Gaps in information and data sharing between countries complicate early warning for hazards that originate across a boundary.
    6. No arbitration route: Downstream countries lack the consensus to build alliances that can deal with China, and there is no scope for international arbitration. Even a signed agreement would face a state that does not follow such international norms, as the South China Sea dispute shows.

    What would stronger cooperation require?

    1. Continuous data sharing: Cooperation would necessarily include continuous sharing of hydrological, weather and climate data across the boundary.
    2. Paying for upstream observation: Where sustained monitoring carries a cost, downstream countries could co invest in upstream observation systems or pay for specialised datasets, creating a model that benefits both sides.
    3. Standing operational machinery: Automated public warning systems, joint scientific studies and regular emergency exercises would complement the data arrangements.
    4. A landscape rather than a national frame: A nation state centric, container approach does not fit the Himalayas, since these disasters do not confine themselves within national boundaries and their ramifications run across the landscape.

    Challenges to hydropower expansion in the Himalayas

    1. Projects sit in the highest seismic risk zones: Much of the Himalayan arc falls in seismic zones IV and V, so a design earthquake is a live engineering assumption rather than a remote one. Eg. The 2011 Sikkim earthquake damaged structures at the Teesta III project and halted work.
      The Fix: Make site specific seismic hazard assessment and independent design review a published precondition for financial closure, not a post clearance formality.
    2. Sediment load shortens the working life of a project: Himalayan rivers carry among the world’s highest silt loads, which abrades turbines and fills reservoirs faster than design assumptions allow. Eg. Run of the river plants on the Alaknanda and Bhagirathi shut down repeatedly during the monsoon for desilting.
      The Fix: Require measured basin sediment yield data in the detailed project report and size desilting capacity against it rather than against a regional average.
    3. Cascade layouts convert one failure into several: Projects built in series on the same river mean an upstream breach delivers debris and water straight into the next structure. Eg. The 2021 Chamoli flood destroyed the Rishiganga project and then struck the Tapovan Vishnugad project downstream.
      The Fix: Assess clearances at the level of the whole river cascade, so cumulative and cascading failure is evaluated once rather than project by project.
    4. Tunnelling destabilises slopes and drains aquifers: Long headrace tunnels cut through fractured rock, dewater springs and remove support from the slopes above. Eg. Land subsidence in Joshimath in 2023 followed years of tunnelling and construction in the same valley.
      The Fix: Publish pre construction and post construction spring discharge and slope movement monitoring for every tunnelled project, with construction halted on a defined trigger.
    5. Rehabilitation is settled before the risk is understood: Displaced communities are resettled onto land whose hazard exposure has not itself been mapped. Eg. Resettlement colonies for Himalayan projects have been sited on debris fans and old landslide zones.
      The Fix: Require the resettlement site to carry its own hazard clearance before the displacement award is finalised.

    Conclusion

    Himalayan risk now runs through infrastructure as much as through geology. The two positions that cannot both hold are that dams are national assets worth building at scale and that the floods which destroy them cross three borders within minutes, with no obligation on the upstream state to say what is coming. Data sharing, not engineering standards, is the binding constraint on early warning. The concrete thing to watch is whether the India China expert level mechanism is widened past monsoon river flow data to cover glacial lake and reservoir conditions.

    [3rd September 2026] The Hindu OpED: Many layers

    Question (2024, GS3): “Elucidate the importance of buffer stocks for stabilizing agricultural prices in India. What are the challenges associated with the storage of buffer stock? Discuss.
    Linkage: This question directly addresses the core policy tool used in onion management: state-led procurement and buffer stocking to counter short-term price volatility. It highlights the storage and logistical bottlenecks that lead to post-harvest collapses.

    Mentor Comment

    Onion price management has again run through a sequence of export restrictions and post collapse procurement, and neither has protected the farmer or the consumer. Since the 1960s Indian food policy has balanced affordable consumer prices against remunerative producer prices, with state intervention aimed at managing short term volatility rather than the underlying cause. Erratic weather and the absence of long term relief have made that balancing act harder to hold. The tension is that every corrective step arrives after farmers have already made production decisions and after prices have already collapsed, so the intervention reaches neither all farmers nor all grades of produce.

    What has the Centre’s onion trade policy been since 2023?

    1. The export ban: The government banned onion exports from December 2023 to May 2024.
    2. The price floor that replaced it: A minimum export price of $550 per tonne was imposed, which sets the lowest price at which a consignment may legally leave the country and works as a soft restriction on exports. A 40 per cent export duty was imposed alongside it.
    3. The rollback: The duty was reduced to 20 per cent in September 2024 and abolished in April 2025.

    Why does intervention after the event fail farmers?

    1. Policy changes after the sowing decision: The government often changes its position after farmers have made production decisions based on the price they expected.
    2. The procurement price was below cost: During the rabi harvest, onion farmers in Maharashtra, the country’s principal supplier, argued that the Centre’s procurement price of ₹12.35 per kg would not cover cultivation costs.
    3. The correction came too late for many: The Centre subsequently raised the price to up to ₹26.45 per kg. Many farmers could not capture the higher value, including some who had already sold at ₹1 per kg because of low quality and lack of storage.
    4. Coverage is partial by grade: Intervening after prices have already collapsed does not reach all farmers or all grades of produce.

    What pressures exposed the flaw this year?

    1. Rainfall at the wrong point in the cycle: Abnormal rainfall at the time of harvest hit the crop directly.
    2. A kharif shortfall in the main supplying State: Maharashtra recorded a 5 per cent to 7 per cent drop in the kharif crop.
    3. Onion resists buffering: The known difficulties of storing onion and of maintaining large buffers compound every supply shock rather than absorbing it.
    4. Manipulation is the secondary issue: The government has alluded to some price manipulation, and the dominant problem remains that policy keeps reacting rather than acting in advance.

    What proactive measures does the record point to?

    1. Storage: Improving storage options is the first named measure, since it is what allows a crop to be held past a price trough.
    2. Trade policy stability: A less erratic trade policy would let farmers price the export channel into their sowing decisions.
    3. Inter regional movement: Moving stock more efficiently between regions addresses the distribution failure rather than the production one.
    4. Price shock protection: Protecting farmers against price shocks is the fourth measure, and it operates before a collapse rather than after it.

    Does Tamil Nadu’s targeted subsidy resolve the problem or move it?

    1. The design: Tamil Nadu will buy 1,000 tonnes of onions to distribute 1 kg per ration card at ₹35.
    2. What it gets right: The design discourages hoarding while allowing private retail prices to cool down.
    3. The delivery channel is the risk: Distribution runs through a dry grain public distribution system network, which was not built for a crop that spoils quickly.
    4. The economic case has a threshold: That case could collapse if post harvest losses exceed 10 per cent to 15 per cent, and onion is more susceptible to such losses than wheat or rice.
    5. Persistence is the second risk: The case also weakens if the subsidy has to be continued rather than used once.
    6. Replication would exhaust the buffer: If other States adopt similar measures, the Central buffer could be quickly exhausted, more so given this year’s high storage losses of around 30 per cent.
    7. Pressure transfers to the Centre: The State scheme will impose pressure on the Centre to maintain a steady supply behind it.

    Challenges to stabilising onion prices

    1. Onion is bulky, perishable and stored without a cold chain: Farm level storage relies on ventilated structures whose losses rise sharply in a wet post monsoon. Eg. The traditional onion chawls of Nashik are open sided sheds with no humidity control.
      The Fix: Link the storage capital subsidy to a verified ventilation and moisture standard rather than to built area alone.
    2. Production is geographically concentrated: A weather event in one district cluster moves the national price because supply is not spread across regions. Eg. Lasalgaon in Nashik sets the reference price for the country’s onion trade.
      The Fix: Build procurement and modern storage capacity in Madhya Pradesh, Karnataka and Gujarat so the national price is not set by one belt.
    3. Sudden trade restrictions cost long term market access: Buyers who lose supply once diversify permanently, so the export channel is thinner when the surplus returns. Eg. Bangladesh and Sri Lanka shifted to Chinese, Pakistani and Egyptian onion during the Indian export restrictions.
      The Fix: Announce any trade measure with a fixed minimum notice period and a stated expiry date written into the notification.
    4. Procurement covers only a buffer, not the crop: Agency purchase is sized to stabilise consumer supply, so the price the farmer receives is still set by the open market. Eg. National Agricultural Cooperative Marketing Federation of India (NAFED) buying is confined to buffer accumulation and market release.
      The Fix: Add a deficiency price payment triggered on the mandi price falling below assessed cultivation cost, paid directly rather than through purchase.
    5. Farmers sow without a forward price signal: Acreage decisions are made months before the price is known, which is what produces the alternating glut and shortage. Eg. A remunerative rabi price pulls extra acreage into the next kharif sowing and depresses that crop’s price.
      The Fix: Publish an official pre sowing advisory each season carrying expected national acreage and an indicative price band.

    Conclusion

    Onion policy is being run as a series of corrections applied after the price has already moved. What remains unreconciled is that every correction reaches the farmer after both the sowing decision and the distress sale are complete. Storage capacity and orderly movement of stock are the only interventions that operate before a collapse rather than after it. Whether the Centre holds one trade regime steady through a full price cycle is the test of whether the approach has changed.
