  • Pichavaram mangroves valued at ₹2,485 crore: study

    Pichavaram mangroves valued at ₹2,485 crore: study

    Why in the News

    A study of the Pichavaram mangrove ecosystem in Tamil Nadu has put its total economic value (TEV) at ₹2,485.38 crore, with a per hectare value of ₹1.83 crore. The valuation covers ecological, economic and social benefits together, and includes a separate blue carbon assessment of what the forest stores. The study was carried out at the Centre for Ecological Economics and Natural Resources, Institute for Social and Economic Change, Bengaluru, and was funded by the Forest Genetics Division, Coimbatore. The tension it identifies is that most of what a mangrove supplies is non market in nature, so it never enters the accounts that development planning actually uses.

    What is ecosystem service valuation?

    1. About: Ecosystem service valuation attaches a monetary figure to the benefits a natural system supplies, so that those benefits can be compared against the returns from converting the same land to another use.
    2. The four service categories: Mangrove systems supply provisioning, regulating, supporting and cultural ecosystem services. Provisioning covers physical output such as fish, regulating covers functions such as storm buffering and climate regulation, supporting covers processes such as nutrient cycling, and cultural covers non material benefits.
    3. Total economic value: TEV is the aggregate of all these service flows expressed in one figure, rather than only the marketed output the system yields.

    What did the valuation measure?

    1. The headline value: The total economic value of the Pichavaram mangrove ecosystem stands at ₹2,485.38 crore, and the per hectare value at ₹1.83 crore.
    2. Sediment holds more carbon than the trees: The analysis found that mangrove sediments constitute a more substantial carbon reservoir than the vegetation.
    3. Soil carbon density: Average soil organic carbon stock was estimated at 251.14 tonnes of carbon per hectare, generating an economic value of ₹90.24 lakh per hectare.
    4. Combined blue carbon asset: With vegetation and soil carbon pools taken together, the total blue carbon asset value of the ecosystem is ₹1,612.40 crore. Blue carbon is the carbon captured and stored by coastal and marine vegetation and the sediment beneath it.

    Why do these benefits stay out of development planning?

    1. The services are non market: Several ecological benefits are non market in nature and are not reflected in market transactions, so they generate no price a planner can read.
    2. Undervaluation is the consequence: Many ecosystem services remain undervalued in conventional development planning even where their contribution to ecological sustainability and human well being is established.
    3. Valuation is the bridge: A single expressed figure allows a non market service to be set against a marketed alternative use of the same coastal land.

    What makes Pichavaram ecologically significant?

    1. Status: It is deemed one of the most ecologically significant coastal wetland ecosystems in India.
    2. Biodiversity and fisheries: It supports biodiversity conservation and fisheries productivity.
    3. Coastal protection and climate regulation: It provides coastal protection, climate regulation and blue carbon sequestration.
    4. Livelihood security: It underpins livelihood security for the coastal communities that depend on it.

    How was the study built?

    1. Primary and secondary data: The assessment combined primary field data with secondary sources rather than relying on modelled estimates alone.
    2. Household survey base: Primary information was collected from 302 households across five mangrove dependent villages.
    3. The villages covered: The five are MGR Thittu, Kalaignar Nagar, Chinnavaikal, Patriadi and Mudasalodai.

    What does the study recommend?

    1. Valuation inside planning: Ecosystem service valuation should be integrated into coastal development planning and environmental decision making.
    2. Mangroves as nature based solutions: Mangroves should be recognised as key nature based solutions for climate adaptation and disaster risk reduction.
    3. Finance instruments: Blue carbon financing mechanisms, carbon credit programmes and Payment for Ecosystem Services schemes should be developed for these systems.

    Challenges to using ecosystem service valuation in coastal planning

    1. A non market service produces no cash flow: A protective service is realised only when the hazard it guards against actually occurs, so it never appears in a project’s financial statement. Eg. Mangrove storm buffering shows up as damage avoided during a cyclone landfall, which no project account records.
      The Fix: Require the ecosystem service value of the land to be entered as a stated line item in the cost benefit statement of every coastal infrastructure clearance.
    2. Valuation methods are contested: Survey based techniques such as willingness to pay measure what nearby residents can afford rather than what the service is worth to the wider economy. Eg. Household surveys in poor mangrove dependent villages return low willingness to pay figures for the same service that protects a city downstream.
      The Fix: Publish the method, the sample and the confidence range alongside every headline valuation figure so the number can be contested on its assumptions.
    3. Aquaculture and land conversion drive mangrove loss: The land use that competes with mangrove is profitable, immediate and privately captured, while the service lost is diffuse and public. Eg. Shrimp pond expansion along the Tamil Nadu and Andhra Pradesh coast has cleared mangrove and adjoining back swamp.
      The Fix: Tie Coastal Regulation Zone enforcement to satellite based mangrove cover monitoring with annual public reporting at the district level.
    4. Blue carbon credits lack a settled soil accounting standard: Sediment carbon is the largest pool and the least standardised, so the same forest yields different credit volumes under different protocols. Eg. Soil carbon is measured to one metre depth in some protocols and deeper in others.
      The Fix: Adopt a single national measurement protocol for mangrove soil organic carbon before any credit is issued against Indian mangrove land.
    5. Restoration often replaces hydrology with planting: Plantation drives on sites that were never mangrove habitat produce low survival and no service recovery. Eg. Monoculture planting on open mudflats has repeatedly failed where tidal flushing was never restored.
      The Fix: Restore tidal connectivity and creek hydrology first, and allow natural regeneration to determine species composition.

    Conclusion

    A valuation changes nothing by itself. It changes outcomes only when the figure enters the document that decides land use, and coastal zone plans in India are still written without one. Tamil Nadu’s coastal clearances are the place this will show. The marker to watch is whether an approval order for coastal land begins citing a per hectare service value against the project it is approving.

    Back2Basics

    1. Location: The Pichavaram mangrove forest lies in Cuddalore district on the Tamil Nadu coast.
    2. Setting: It sits in the estuarine complex formed between the Vellar and Coleroon rivers, adjoining the Killai backwater.
    3. Scale: It is among the largest mangrove forests in India and is made up of a network of islets separated by tidal creeks.
    4. Composition: Avicennia and Rhizophora are the dominant mangrove genera across the forest.

  • UN sets pathway to tackle ‘inevitable breach’ of the 1.5°C global warming limit

    UN sets pathway to tackle ‘inevitable breach’ of the 1.5°C global warming limit

    Why in the News

    The United Nations Environment Programme (UNEP) has for the first time set out a detailed “overshoot, peak, and decline” pathway for global warming. Its report, Limiting Overshoot, states that a breach of the 1.5 degrees Celsius limit is now unavoidable and will bring irreversible ecological losses that no adaptation initiative can undo. That limit is the central goal of the Paris Agreement, 2015, which committed parties to holding the rise in average global temperatures well below 2 degrees Celsius and to pursuing efforts to limit it to 1.5 degrees Celsius above pre industrial levels. The shift is in the framing rather than in the science: the objective being planned for is no longer the prevention of a breach but the management of one, described in the report itself as by no means an acceptable or preferred pathway and simply the best remaining option.

    What is the “overshoot, peak, and decline” pathway?

    1. The sequence it describes: Average global temperature crosses the 1.5 degrees Celsius limit, rises to a peak, and is then brought back down below the limit by 2100.
    2. What it tries to control: With the crossing treated as fixed, the two variables left are the height of the peak and the length of time spent above the limit, and the pathway seeks to hold both as low as possible.
    3. What it requires that mitigation alone does not: Returning below the limit after a peak requires removing carbon dioxide already in the atmosphere, not only stopping additional emissions.

    What do the warming projections show?

    1. The breach is imminent: Global warming will cross 1.5 degrees Celsius in the next few years.
    2. Full delivery of every pledge still overshoots: A scenario in which every country delivers on its national climate plan and its net zero target puts peak warming at 1.8 degrees Celsius.
    3. Current policies point far higher: They point to a rise of about 2.6 degrees Celsius by 2100, within a range of 1.9 to 3.6 degrees Celsius.

    What are the compounding costs of time spent above 1.5 degrees Celsius?

    1. Sea level and ocean systems: Sea level rise accelerates, and coral reefs collapse.
    2. Cryosphere: Glacier loss exceeds a quarter of global glacier mass by 2100.
    3. Food systems: Global food production declines by up to 14% by 2050 without effective adaptation.
    4. Tipping points: The odds rise of irreversible transitions in the West Antarctic and Greenland ice sheets, the Atlantic Meridional Overturning Circulation, the ocean current system that redistributes heat across the Atlantic, and the Amazon.

    Why is reversing an overshoot harder than avoiding it?

    1. Delay adds warming at a fixed rate: Every five years of continued high emissions adds roughly 0.1 degrees Celsius to peak warming.
    2. Removing the same warming costs far more than adding it: Reversing that 0.1 degrees Celsius afterwards means pulling about 220 billion tonnes of carbon dioxide out of the atmosphere, over and above whatever is still being emitted.
    3. Emission cuts alone no longer close the gap: A steep scaling up of nature based removals, such as large reforestation programmes, is required alongside them.

    Why does the report single out methane?

    1. A first for the United Nations: This is the first time a report of this kind has placed significant stress on methane rather than treating carbon dioxide as the only lever.
    2. Its share of the problem is large: Methane contributes about 0.5 degrees Celsius of current warming.
    3. It is the fastest acting lever available: Cutting methane is described as the most effective way to slow warming in the near term, which is precisely what holding down the peak requires.

    How was the diplomatic ground for conceding an overshoot laid?

    1. The concession was made first at a climate conference, not in a science report: The 30th UN Climate Change Conference (COP30), held in 2025 at Belém in Brazil, produced the consensus “Global Mutirão” decision, mutirão being a Portuguese term for collective effort.
    2. What made it significant: It was the first COP text to concede that a temporary overshoot of the 1.5 degrees Celsius limit was likely, given how fast the remaining carbon budget was being spent.
    3. The political framing accompanying the report: This summer’s heat, wildfires and floods have been described as a warning of what lies ahead, with the stated objective now to make the overshoot as small and as short as possible.

    Challenges to an overshoot, peak and decline pathway

    1. Carbon removal at the required scale does not exist: The pathway assumes gigatonne scale removal that current technology and land availability cannot deliver. Eg. Operating direct air capture plants worldwide remove a volume measured in thousands of tonnes a year against a requirement measured in billions.
      The Fix: Separate emission reduction and removal targets in every nationally determined contribution, so removal cannot be used to discount a country’s reduction obligation.
    2. Overshoot creates a moral hazard in near term policy: Once a temporary breach is accepted as planned for, the incentive to cut now weakens, because the shortfall is deferred to a future removal obligation. Eg. Net zero pledges dated to mid century already rely on unspecified future removals to close the residual gap.
      The Fix: Fix binding five year interim carbon budgets, so a country’s compliance is assessed against cumulative emissions rather than against a distant target year.
    3. Tipping points are not reversible when the temperature comes back down: Bringing temperature below the limit later does not restore a system that has already crossed its threshold. Eg. An ice sheet that has begun irreversible retreat continues losing mass even after warming stabilises.
      The Fix: Set the peak temperature, rather than the end of century value, as the headline metric against which climate policy is assessed.
    4. Nature based removal competes with food and land rights: Large reforestation programmes need land that is already used for cultivation, grazing or forest dwelling communities. Eg. Plantation drives on land recorded as degraded have displaced pastoral and forest dependent use in several countries.
      The Fix: Require free, prior and informed consent and a land tenure audit before any removal project is counted towards a national target.
    5. The cost falls on countries that did not cause the overshoot: Adaptation finance to survive the period above the limit is needed by economies with the least capacity to raise it. Eg. Small island developing states face permanent territorial loss from sea level rise they contributed almost nothing to.
      The Fix: Tie disbursement from the loss and damage fund to a published overshoot period schedule, so the finance arrives during the years the harm is being incurred.

    Conclusion

    The value of this pathway is that it makes the cost of delay arithmetic rather than rhetorical. Warming added by continuing to emit is cheap and automatic; warming removed afterwards is expensive, slow and dependent on technology that has not been built at scale. That asymmetry is what converts a distant target year into an immediate operational question about the next few years of emissions. The reform that follows is to shift the metric climate policy is judged on, from a date by which a country claims to reach balance to the height of the peak its emissions in this decade produce.

  • SC seeks govt. explanation on IPS deputation in CAPFs

    SC seeks govt. explanation on IPS deputation in CAPFs

    Why in the News

    The Supreme Court has sought an explanation from the Union Home Secretary on the implementation of its judgment of 23 May 2025, which directed the Centre to progressively reduce the deputation of Indian Police Service (IPS) officers to senior posts in the Central Armed Police Forces (CAPFs).

    What did the 2025 judgment direct?

    1. The direction: Deputation posts held by IPS officers in the Senior Administrative Grade (SAG), the level up to the rank of Inspector General, in the CAPFs were to be progressively reduced over a period of time, within an outer limit of two years.
    2. The Bench: The ruling was delivered by a two judge Bench, one of whose members has since retired.
    3. The direction has been tested once already: The Union Home Ministry’s review petition against the judgment was dismissed on 28 October 2025.

    What has the Centre reported as compliance?

    1. A cadre review across every force: Following the dismissal of the review petition, all CAPFs were directed to submit detailed cadre review proposals, which the Ministry examined and forwarded to the Department of Personnel and Training (DoPT) with the Home Minister’s approval.
    2. The proposals are in the pipeline, dated: Cadre review proposals for the CRPF, BSF, CISF, ITBP and SSB were sent between 27 July and 3 August 2026, and were forwarded to the Department of Expenditure with the DoPT’s observations and recommendations on 17 August.
    3. The remaining steps have not been taken: After the Department of Expenditure comments, the proposals go to the Cadre Review Committee headed by the Cabinet Secretary, whose recommendations are then to be considered for approval by the competent authority.
    4. Other measures claimed: The Ministry stated that it had also examined the issue of IPS deputation and undertaken statutory changes.

    Why does the Court read the compliance record differently?

    1. Deputations continued after the judgment: An affidavit informed the Court that 46 IPS officers have been brought on deputation to the CAPFs up to the SAG level since the 2025 ruling.
    2. The Bench questioned the premise of the practice: It asked whether there are no competent officers within the CAPFs to hold responsible positions, and described the position as totally wrong.
    3. The service record cited against the practice: Officers with over 25 years of service defend the borders and have made supreme sacrifices, and the Bench held that a strong lobby leaves those cadre officers completely stifled.

    How does the CAPFs (General Administration) Act, 2026 change the dispute?

    1. A statute now occupies the ground the judgment covered: The Central Armed Police Forces (General Administration) Act, 2026 was published in the Gazette on 9 April, and the stated effect is to circumvent the 2025 judgment.
    2. The Act is itself under challenge: Five writ petitions challenging the legislation have been filed and are listed for hearing on 18 November.
    3. The affected constituency is organised: Members of the All Ex-Paramilitary Forces Welfare Association staged protests against the Bill before its enactment.
    4. The next date on the compliance track: The contempt matter is listed for hearing on 22 September.

    Challenges to reducing IPS deputation in the CAPFs

    1. The forces were designed around an officer shortfall they never closed: Direct entry recruitment into CAPF cadres has not kept pace with sanctioned strength at senior levels, which is the stated justification for deputation in the first place. Eg. Vacancies across CAPF officer ranks have been reported repeatedly to Parliament by the Ministry of Home Affairs.
      The Fix: Fix a dated recruitment and promotion calendar in each cadre review, so the shortfall that justifies deputation is closed rather than carried forward.
    2. Cadre review is an executive process with no judicial deadline attached: Every stage between a force’s proposal and the competent authority’s approval is discretionary in timing. Eg. The proposals here moved between three departments over several months without reaching the Cadre Review Committee.
      The Fix: Attach an outer time limit to each stage of the cadre review chain, reported to the Court as a compliance schedule rather than as a status update.
    3. Command experience is concentrated where promotion is blocked: Officers who spend a full career in one force acquire the operational knowledge that senior posts need, and are then passed over at exactly that level. Eg. Border guarding, counter insurgency and industrial security each demand force specific expertise that a short deputation tenure cannot build.
      The Fix: Reserve a fixed proportion of Inspector General level posts in each force for cadre officers, notified in the recruitment rules rather than settled case by case.
    4. A statute can displace a judicial direction unless the underlying defect is cured: New legislation on the same subject shifts the dispute from contempt to constitutional validity and restarts the litigation clock. Eg. The five writ petitions against the 2026 Act put the question back at the beginning after a judgment and a dismissed review.
      The Fix: Amend the recruitment rules of each force to give effect to the direction, so compliance rests on subordinate legislation the Court has already read rather than on a fresh statute.
    5. Organisational identity is unresolved in law: The forces are described as paramilitary in public and as police organisations in service rules, and the ambiguity drives the parity claims on pay, pension and command. Eg. The demand for organised group A service status for CAPF cadres was itself settled only through litigation.
      The Fix: Settle the service classification of each force explicitly in the rules framed under the governing statute, so command structure follows from a stated status.

    Conclusion

    The question before the Court has changed shape since it was first answered. It began as a service dispute about who commands a force, moved to whether a direction on that dispute was being implemented, and now turns on whether a statute passed after the judgment can occupy the same ground. That last question is the one that decides the other two, and it is the pending challenge to the new Act, not the contempt proceeding, that will settle it. What to watch is whether the recruitment rules of the individual forces are amended at all, because a direction that never reaches the rules governing promotion has not been implemented whatever the affidavits record.

    Back2Basics: Central Armed Police Forces

    1. What they are: Seven armed forces of the Union under the Ministry of Home Affairs, distinct from the armed forces under the Ministry of Defence and from the State police, raised for internal security and border guarding duties.
    2. The seven forces: Assam Rifles, Border Security Force, Central Industrial Security Force, Central Reserve Police Force, Indo-Tibetan Border Police, National Security Guard and Sashastra Seema Bal.
    3. Command structure: Each force has its own directly recruited cadre, and senior posts are filled by a combination of that cadre and IPS officers on deputation from State cadres.
    4. Constitutional basis: They are raised under Entry 2A of the Union List, which covers deployment of any armed force of the Union in a State in aid of the civil power.

  • Private players seek ‘green energy’ status for N-power to raise funds

    Private players seek ‘green energy’ status for N-power to raise funds

    Why in the News

    Private players have sought green energy status for nuclear power so that nuclear projects can access green bonds, green loans and blended financing. The demand was made at a stakeholder consultation held by NITI Aayog, attended by around 150 participants from 60 organisations. India opened its tightly regulated civil nuclear sector to private participation last year and targets 100 gigawatt electric (GWe) of nuclear capacity by 2047, a target that needs at least $228 billion of investment. The instruments that supply the cheapest climate capital are closed to the technology, because the Ministry of Finance’s Sovereign Green Bond Framework does not include nuclear energy.

    What are India’s green finance frameworks?

    1. Sovereign Green Bond Framework: Maintained by the Ministry of Finance, it defines which project categories the proceeds of a sovereign green bond may be applied to, and nuclear energy is not among them.
    2. RBI framework for green deposits: It sets the conditions under which a bank or deposit taking institution may raise and deploy deposits labelled green.
    3. SEBI framework for green debt securities: It governs disclosure and use of proceeds for green bonds issued in the Indian securities market.

    Why do private players want nuclear classified as green energy?

    1. Access to a cheaper pool of capital: Green status would open green bonds, green loans and blended financing schemes to nuclear projects, which is the specific relief sought.
    2. The three frameworks are the gatekeepers: Industry participants asked for a review of all three, because exclusion from any one of them closes a distinct funding channel.
    3. The multilateral position is already moving: The World Bank and the Asian Development Bank are reviewing their own restrictions on nuclear investments, which is the precedent cited for a domestic review.

    What is the infrastructure status demand, and where does it stand?

    1. The demand: Private players separately suggested that nuclear power projects be accorded infrastructure status.
    2. The official reading: In NITI Aayog’s view nuclear power is already covered under the infrastructure framework, because the Harmonised Master List of Infrastructure Sub-sectors maintained by the Department of Economic Affairs includes electricity generation.
    3. What is actually being asked for: The gap is one of certainty rather than of category, and a clarification in this regard may be needed.

    What else must fall into place for the 100 GWe target?

    1. The rules are not final: The final rules under the SHANTI Act, the statute governing the opening of the sector, are likely to be ready in the next two to three months, with stakeholder consultations on the draft rules currently underway.
    2. Project timelines: The gestation period of nuclear power projects in India needs to be reduced if capacity is to be added at the pace the target implies.
    3. Site selection is a binding constraint: Identifying sites will be a major challenge as capacity scales, and site selection committees are working with the States.
    4. Fuel security beyond uranium: Thorium based technologies need to be developed to strengthen India’s long term energy security.

    Challenges to green energy status for nuclear power

    1. Taxonomies elsewhere have attached conditions rather than granting blanket inclusion: Where nuclear has been admitted to a green classification, it has come with waste and safety conditions that projects must meet continuously. Eg. The European Union’s taxonomy admitted nuclear only as a transitional activity with disposal facility and accident tolerant fuel conditions.
      The Fix: Draft any Indian inclusion as a conditional category tied to disclosed waste management and decommissioning provisioning, so the label survives investor scrutiny.
    2. Green bond investors price on verifiability, not on carbon content alone: A large share of green mandates screen out nuclear by policy, so a taxonomy change does not by itself create demand. Eg. Several sovereign and pension fund mandates exclude nuclear on exclusion lists set independently of national taxonomies.
      The Fix: Pair inclusion with a certified external review of use of proceeds, so a nuclear tranche can be assessed on the same evidence as a renewable one.
    3. Liability exposure sits ahead of the financing question: Supplier liability under India’s civil nuclear liability law has deterred private and foreign participation for over a decade. Eg. The Civil Liability for Nuclear Damage Act, 2010 gives the operator a right of recourse against the supplier, which foreign vendors have cited as a barrier.
      The Fix: Settle the recourse position by statute or by a capped insurance pool before private capital is asked to price a project.
    4. Long gestation makes debt tenors mismatch: Nuclear construction periods run well beyond the tenor of most Indian debt instruments, so refinancing risk sits with the developer. Eg. Domestic bank lending to power projects is typically structured over tenors far shorter than a nuclear build cycle.
      The Fix: Create a dedicated long tenor refinancing window for nuclear projects, on the model used for other long gestation infrastructure.
    5. Public acceptance decides sites, not policy: Land acquisition and local consent have delayed nuclear sites regardless of the financing available. Eg. Protests at Kudankulam in Tamil Nadu delayed commissioning of the plant by years.
      The Fix: Build a statutory local benefit sharing entitlement into site notification, so host districts hold a stake before construction begins.

    Conclusion

    The nuclear expansion has moved past the question of whether private capital is allowed in and reached the question of what that capital will cost. A taxonomy is the cheapest lever the government holds, because reclassification requires no new outlay and changes the interest rate on every subsequent rupee borrowed. Two decision points are dated and worth watching: the final rules under the SHANTI Act in the next two to three months, and whether the Ministry of Finance, the RBI and SEBI open their frameworks for review together or separately.

    Back2Basics: Harmonised Master List of Infrastructure Sub-sectors

    1. What it is: A list maintained by the Department of Economic Affairs in the Ministry of Finance that defines which activities count as infrastructure for policy purposes.
    2. Why the label matters: Inclusion gives a project access to infrastructure lending norms, longer tenor bank finance and easier external commercial borrowing.
    3. How it is organised: Activities are grouped under broad categories such as transport, energy, water and sanitation, communication and social and commercial infrastructure.
    4. How it changes: An institutional mechanism under the Department of Economic Affairs reviews and updates the list, with electricity generation already among the listed sub sectors.

  • Govt rejects GDP criticism, expects ‘informed debate’ once methods understood

    Govt rejects GDP criticism, expects ‘informed debate’ once methods understood

    Why in the News

    The Ministry of Statistics and Programme Implementation (MoSPI) has issued a six point rebuttal asserting that its methods and its recently released quarterly numbers are correct. Data showed India’s Gross Domestic Product (GDP) grew 7.8 per cent in April to June, significantly higher than the Reserve Bank of India’s forecast of 7 per cent. Economists, former bureaucrats and politicians then questioned the figure, one claim putting nominal growth at 2.6 per cent and real growth “close to 0”. The dispute turns on a single technical point. A number from the old 2011-12 base series and a number from the new 2022-23 base series are being compared with each other, and the ministry’s position is that they cannot be.

    What is double deflation?

    1. Gross Value Added, first: To find the value added by a sector, the value of the inputs it uses is subtracted from the value of the output it produces. This gives Gross Value Added (GVA) in current prices, or nominal terms.
    2. Deflating twice: To reach real GVA, the output value and the input value are each adjusted by their own inflation rate rather than by a single common rate.
    3. Why a single rate distorts: Deflating inputs and outputs by the same number is problematic when input and output prices change at different rates, which is exactly when a sector’s real growth is hardest to read.

    What did the criticism of the quarterly numbers claim?

    1. The deflator objection: Some economists were unconvinced by the figure used to deflate the manufacturing sector’s GVA in current prices to arrive at the inflation adjusted estimate.
    2. The growth rate claim: A former Finance Secretary argued that nominal GDP growth for April to June should be 2.6 per cent, and in real terms close to zero.
    3. The allegation of manipulation: The same critic claimed that April to June 2025 nominal GDP was revised down from Rs 86 lakh crore to Rs 80 lakh crore in order to make growth in April to June 2026 look better.

    How did the statistics ministry answer the comparison?

    1. The two figures sit in different series: The ministry pointed out that the Rs 86.05 lakh crore figure belongs to the old GDP series, which had 2011-12 as its base year.
    2. The revision has a stated cause: The move to Rs 80.00 lakh crore in the new series arose from successive revisions to the GDP series following the change in base year, the incorporation of improved data sources and methodologies, and the updation of available indicators.
    3. The inference is rejected: The ministry held that it is “incorrect to interpret the difference as a deliberate downward revision of last year’s GDP to mechanically increase the current year’s growth rate”.
    4. The method objection: One cannot compare GDP numbers drawn from different series to arrive at a growth rate, which is what the critic had done.

    What changed in the new GDP series?

    1. A new base year: The series with 2022-23 as its base was released in February this year, bringing in new sources of data and several methodological changes in the calculation of GDP.
    2. Long sought changes: Those changes include ones that economists and international agencies such as the International Monetary Fund (IMF) had been calling for over several years.
    3. Double deflation extended to all sectors: Before the new series, MoSPI applied double deflation only to agriculture and to mining and quarrying, deflating every other sector’s inputs and outputs by the same number using the Wholesale Price Index and the Consumer Price Index.
    4. A finer deflator set: The Producer Price Index now supplies more than 300 deflators for different parts of GDP, up from around 180 under the old series, which makes the new estimates more accurate.
    5. Other inputs behind the revisions: The updated Index of Industrial Production series and the Banking Services Price Index released earlier this year also fed the revisions, including the January to March growth rate being raised from 7.8 per cent to 8.6 per cent.

    Conclusion

    The disagreement is not about whether the economy grew. It is about whether a statistical office is entitled to change its base year, its data sources and its deflation method at the same time, and then publish a growth rate against a back series it has itself rebuilt. The ministry’s answer is that comparability lives within a series and not across two of them. The test of that answer is transparency, and what to watch is whether the full back series on the new base is published in a form that lets an outside statistician reproduce the quarterly numbers independently.

    Back2Basics: Producer Price Index

    1. What it measures: A Producer Price Index tracks the average change over time in prices received by domestic producers for their output, measured at the factory gate.
    2. How it differs from the Wholesale Price Index: It excludes trade margins, transport costs and indirect taxes, so it reflects the producer’s own realisation rather than the price at which a good changes hands in wholesale markets.
    3. Why it suits deflation: It covers services as well as goods, which a wholesale price measure does not, so it can deflate sectors a goods only index cannot reach.
    4. Status in India: India has worked towards a PPI on the recommendation of an official working group, with the wholesale index historically serving as the main producer side price measure.

  • Forex swap rakes in over $136 bn

    Forex swap rakes in over $136 bn

    Why in the News

    Foreign exchange inflows under the Reserve Bank of India’s (RBI) special swap facility have crossed $136 billion, surpassing all projections. The facility was introduced on 8 June this year to deal with forex outflows caused by high oil prices and by the exit of Foreign Portfolio Investors from the stock market. The task has now shifted from raising dollars to managing what they release. Every dollar brought in creates rupee liquidity in the banking system, and the RBI has already begun absorbing it to stop call rates falling below the policy rate.

    What is the RBI’s special USD-INR swap facility?

    1. What it does: The facility lets a bank exchange dollars raised abroad for rupees with the RBI at a concessional rate, with a commitment to reverse the exchange at a future date.
    2. What it covers: It applies to three instruments, Foreign Currency Non-Resident (Bank) or FCNR(B) deposits, Overseas Foreign Currency Borrowings (OFCBs), and External Commercial Borrowings (ECBs).
    3. Why it was opened: It was designed to attract fresh foreign currency at a time when the rupee and India’s reserves were under pressure from oil prices and portfolio outflows.

    Where did the $136 billion come from?

    1. The total mobilised: A total of $1,36,377 million has been mobilised, according to data released by the RBI.
    2. FCNR(B) deposits dominate: Deposits by overseas Indians accounted for $1,27,226 million, the overwhelming share of the mobilisation.
    3. Corporate borrowing contributed little: OFCBs brought in $5,260 million and ECBs a further $3,891 million.

    Why does the RBI’s short forward dollar position matter now?

    1. What a short forward position is: Short forward dollars are currency derivative contracts in which the RBI commits to sell dollars at a future date at a predetermined rate.
    2. Why the RBI built one: The instrument defends the rupee without drawing down spot reserves immediately, so the headline reserve figure holds while the commitment sits in the forward book.
    3. The size of the book: The RBI carries an outstanding short forward position of $137 billion, close to the entire mobilisation under the swap facility.
    4. How the two connect: If the RBI decides not to roll over those positions, it may use the excess reserves generated from the FCNR(B) scheme to deliver the dollars it has contracted to sell.

    What does the inflow do to domestic liquidity?

    1. Rupees enter as dollars arrive: Delivering on the forward book absorbs rupee liquidity from the banking system, which is why the RBI has begun draining it before call rates slip under the policy rate.
    2. The surplus is large: Banking system liquidity stood at Rs 6.5 lakh crore, and the RBI may absorb part of it so short term money supply does not feed into inflation and borrowing costs stay aligned with the policy rate.
    3. Banks gain a cheap funding base: In the immediate term banks are inclined to use the inflow to strengthen their asset side books and cut their dependence on wholesale deposits.
    4. The longer use is credit: Over a longer horizon the same liquidity can be deployed to fund credit growth.

    Conclusion

    The facility has done more than it was designed to do, and the constraint has moved from the external account to the domestic money market. The decision that now matters is whether the central bank rolls its forward commitments over or lets them run off against the deposits it has raised. Rolling over keeps the liquidity in the system; delivering drains it. That choice, and the pace at which it is made, is what will determine short term rates over the coming quarter.

    Back2Basics: External Commercial Borrowings

    1. What they are: ECBs are loans raised by eligible Indian entities from recognised non resident lenders, denominated in foreign currency or in rupees.
    2. Forms they take: They cover bank loans, buyers’ and suppliers’ credit, and instruments such as foreign currency convertible bonds.
    3. How they are regulated: The RBI governs them under the Foreign Exchange Management Act, 1999, through the automatic route up to prescribed limits and the approval route beyond them.
    4. What the framework controls: The rules set the minimum average maturity, the all in cost ceiling and the end uses for which the borrowed money may be applied.

    [2022] With reference to the Indian economy, consider the following statements :

    1. An increase in Nominal Effective Exchange Rate (NEER) indicates the appreciation of rupee.

    2. An increase in the Real Effective Exchange Rate (REER) indicates an improvement in trade competitiveness.

    3. An increasing trend in domestic inflation relative to inflation in other countries is likely to cause an increasing divergence between NEER and REER.

    Which of the above statements are correct ?

    (b) 2 and 3 only

    (c) 1 and 3 only

  • China, US are in race to connect science with industry. India must catch up [Express]

    China, US are in race to connect science with industry. India must catch up [Express]

    Mentor Comment

    Beijing’s second World Humanoid Games has showcased a Chinese project to become the world’s leading science power, rooted in the Chinese President’s call to mobilise “new quality productive forces” released by the current revolutions in science and technology. The US administration has released Science: A New Golden Age, billed as the first major reset in US science policy since World War II, aimed at reintegrating discovery with production. Both powers are building an ecosystem that connects science with industry, from opposite starting points. India has launched missions on artificial intelligence (AI), semiconductor production and quantum technologies, but its private capital has retreated from science and its state-led scientific institutions remain unreformed.

    How are China and the United States racing toward the same goal from opposite directions?

    1. China’s break with the old growth model: The Chinese President holds that the next phase of growth cannot rely on cheap labour, large-scale manufacturing, infrastructure and capital accumulation, and must come from innovation.
    2. AI diffused across the physical economy: Beijing’s objective is to diffuse AI across robotics, machine tools, automobiles, biotechnology, materials, energy, agriculture and scientific research.
      • It bets that fusing digital intelligence with the world’s largest industrial ecosystem will make China the leading technological power.
    3. From adaptation to original discovery: For decades China absorbed foreign technology, improved it through manufacturing and dominated production. It now wants to move upstream to original discovery.
    4. China’s spending signal: China spent 2.8 per cent of GDP on research and development (R&D) in 2025, and its basic-research expenditure rose by 11 per cent.
    5. China’s four-step logic: AI accelerates discovery; discovery produces technology; technology transforms industry; industrial strength generates national power and a geopolitical edge.
    6. The US reset names its own weakness: Science: A New Golden Age, released in July, recognises American strengths in universities, laboratories, technology companies and capital markets. It acknowledges the erosion of the capacity to turn discoveries into production.
    7. How globalisation split US innovation from manufacturing: Companies designed at home, produced abroad and depended on long supply chains. That model generated wealth and also the vulnerabilities exposed by the pandemic, China’s rise and geopolitical rivalry.
    8. Mirror-image fears: China begins with the largest manufacturing base and moves upstream into science. The US begins with the strongest scientific system and moves downstream into manufacturing. China fears dependence on American technology; the US fears dependence on Chinese production.

    What does “connecting science with industry” actually mean in this contest?

    1. AI as an accelerator of knowledge, not a product: Washington and Beijing see AI not merely as a general-purpose technology but as an accelerator central to the production of new knowledge that in turn transforms industry.
    2. Discovery made continuous with manufacturing: By making discovery continuous with design and manufacturing, AI-driven science transforms production itself and converts scientific speed into economic power and geopolitical capability.
    3. The ecosystem, not the model, is the prize: The contest is not about who unveils the cleverest AI model or the most sophisticated humanoid. It is about building the most effective ecosystem connecting universities, laboratories, entrepreneurs, finance, energy, factories, supply chains and markets.

    Where does India stand as the race intensifies?

    1. Missions exist on paper: Delhi recognises the trend and has launched missions on AI, semiconductor production and quantum technologies, and has a draft robotics policy.
    2. The spending gap: The Economic Survey 2025-26 puts India’s R&D expenditure at 0.64 per cent of GDP, against about 2.8 per cent for China and 3.5 per cent for the US.
    3. The absolute gap is wider: The World Intellectual Property Organisation estimates India’s total R&D spend at $75 billion in purchasing-power-adjusted dollars, against $786 billion for China and $782 billion for the United States. In nominal dollar terms India looks even smaller.

    Why does the first weakness, the retreat of private capital from science, matter most?

    1. Ambition lives in government declarations: Ambition and imagination are concentrated in government declarations at a time when the private sector contributes more than ever to producing knowledge in the US and China.
    2. Indian capital has no science project: Indian capital rarely articulates a project for mastering the new forces of production or a new project for science and basic research.
    3. It was not always so: Jamsetji Tata helped create the Indian Institute of Science in 1909. The Kirloskars and other western Indian business families sent their children to the Massachusetts Institute of Technology from the 1920s, recognising that independent India’s future lay in mastering modern science.
    4. Private philanthropy built the strategic programmes: The Sir Dorabji Tata Trust supported Homi Bhabha in establishing the Tata Institute of Fundamental Research, which formed the nucleus of India’s atomic energy and space programmes. Indian capital has retreated from that tradition.

    Why does the second weakness, unreformed scientific institutions, compound the first?

    1. No overhaul in India’s reform era: China’s reform era, launched in the late 1970s under Deng Xiaoping, put the revitalisation of science and technology at the heart of the Four Modernisations. India’s reform era, beginning in the 1990s, produced no comparable overhaul.
    2. Same American training, different follow-through: India and China both benefited from access to American universities that trained their vast talent pools. China combined that opportunity with massive domestic investment in science and higher education and incentives for researchers to return.
    3. India does not draw talent back: India’s science sector fails to attract its trained talent home, and the shortfall is severe rather than marginal.

    Can “technological sovereignty” be built without global science?

    1. Bureaucratisation, then cultural nationalism: The Congress era saw the steady bureaucratisation of Indian science, and the BJP era is adding cultural nationalism to it.
    2. Mythology is not evidence: Civilisational pride cannot make mythology a substitute for evidence, experiment and scientific temper. India’s most confident claim should be that the greatest Indian contributions lie in the future, not that all modern science was discovered in its past.
    3. The cost of talking tall, once before: Delhi’s radical posturing on technological “self-reliance” in the 1970s and 1980s isolated India from global technological advances. Today there is grandiose talk of “technological sovereignty”.
    4. Two tracks at once: India must deepen cooperation with global science, capital, technology and talent, and at the same time build domestic research, industrial and institutional capacity. Neither track substitutes for the other.

    Challenges to India’s science-industry linkage

    1. Research sits outside the universities that supply the workforce: Most public research is done in mission agencies and Council of Scientific and Industrial Research (CSIR) laboratories, so graduates and firms rarely meet discovery where it happens. Eg. The Defence Research and Development Organisation, the Indian Space Research Organisation, the Department of Atomic Energy and CSIR absorb the bulk of central research spending, and State universities receive a marginal share.
      The Fix: Route Anusandhan National Research Foundation grants preferentially to State universities with mandatory industry co-investment.
    2. Industry does not fund its own research: The private sector contributes 36 per cent of India’s gross R&D expenditure, against 77 per cent in China and 79 per cent in the US and Japan. Eg. The weighted tax deduction on in-house R&D under Section 35(2AB) of the Income Tax Act, 1961 was cut from 200 per cent to 100 per cent from 2020-21, removing the one fiscal incentive firms used.
      The Fix: Restore a weighted deduction tied to patents filed and products commercialised rather than to spending alone.
    3. Deep technology has no patient capital: Venture funds back consumer applications that return within five years, not fabs or materials that need fifteen. Eg. Micron’s assembly and test plant at Sanand, approved in 2023, needed roughly 70 per cent of its project cost as central and Gujarat subsidy before private capital moved.
      The Fix: Deploy the Research Development and Innovation scheme corpus as long tenure, low interest loans and fund-of-funds equity for private deep technology projects.
    4. Public procurement does not buy the first unit: Government buyers demand a track record, so an Indian prototype finds no first customer and licenses abroad. Eg. The United States’ Small Business Innovation Research programme reserves a fixed share of federal agency R&D budgets for small firms’ first contracts, and India has no equivalent set-aside.
      The Fix: Add a first-buyer set-aside in the General Financial Rules for Indian deep technology products validated by a designated national laboratory.

    Conclusion

    The contest India has to enter is an ecosystem contest, and an ecosystem cannot be declared into existence by a mission document. Two things remain unreconciled: a state-led science system that has never been restructured, and a private sector that has stopped funding discovery. Whether Indian capital returns to the tradition that built the Indian Institute of Science and the Tata Institute of Fundamental Research is the marker to watch, and the disbursal of the new research finance corpus to private laboratories is where it will first show.

  • Why risk-monitoring in the Himalayas is like looking for ‘needles in haystacks’

    Why risk-monitoring in the Himalayas is like looking for ‘needles in haystacks’

    Why in the News

    A Senior Fellow of the Energy, Water and Sustainability Program at the Stimson Center, a US based non-profit think tank, has set out the sequence of the recent Nepal flood and the lessons it holds for hazard monitoring across the Himalayas.

    What triggered the Nepal flood, and why is the trigger still uncertain?

    1. A glacial detachment carrying bedrock: The present consensus is that the initial trigger was a glacial detachment that included bedrock on the northern slopes of Langtang Lirung, a 7,000-plus-metre peak in the Langtang range.
    2. The triggering process is not understood: The failure could be related to climate-related risks or to gradual shifts at the site itself.
    3. A slow creep, then a tipping point: Preliminary analysis indicates minor movement of the glacial mass in the weeks or months before the event, followed by a tipping point.

    How did a single glacial failure cascade more than 100 kilometres downstream?

    1. The descent: The failed mass swept down a gully toward the Lhende River, which reaches the Chinese border. The source area was around 5,200 metres, so the flow descended a couple of thousand metres.
    2. A temporary natural dam: The flow deposited a mixture of ice, rock and sediment that blocked the river.
    3. Three contested water sources: Debate continues on how much water came from the glacier itself, from melting of entrained ice, and from water that accumulated behind the landslide dam.
    4. Nine minutes to the border: The dam failed and sent a major pulse of water downstream, which reached the China border in roughly nine minutes. Footage from the Gyirong border facility shows a massive dark wave carrying a large volume of material, not just water.
    5. Back into Nepal within seconds: The border facility sat at a confluence with the Gyirong River tributary, and within seconds of hitting it the flow was already moving back into Nepal. There was no realistic opportunity to warn communities downstream, and many of those who could have generated an alert were themselves swept away.
    6. Dams, hydropower and villages: The flow destroyed dams and hydropower projects downstream, recruited additional sediment, and swept through villages along the river corridor.
    7. Beyond every mapped floodplain: The event continued into Nuwakot district and affected larger market towns in the floodplain, in areas well beyond the 100-year or 500-year floodplain (the extent a flood of that average recurrence interval is expected to reach). This was a thousand-year-plus flood event.
    8. Registered at the India-Nepal border: Significant impacts extended more than 100 kilometres downstream, and the flood pulse also registered at the India-Nepal border.

    Why are cascading hazard chains the larger Himalayan problem?

    1. A pattern across three countries: The same chain has appeared in Chamoli, in Sikkim with the South Lhonak GLOF (glacial lake outburst flood), and in Nepal with the Melamchi disaster.
    2. Climate risk as an amplifier: Climate risks are interacting with and amplifying other disaster risks, and these events are becoming more frequent and more intense.

    Why does hazard monitoring keep missing the sites that fail?

    1. Known high-risk sites exist, and this was not one: Several places around Nepal have been identified as high-risk areas for glacial detachment and surges, and glaciers immediately on the other side of Langtang Lirung are high-priority research sites. This particular location had no red flags.
    2. Hindsight still needs a target: Analysts are examining whether changes could have been detected in the days before the event, but that would still require knowing where to look.
    3. No signal to separate from noise: Monitoring every glacier and every mountainside that could collapse is not feasible without some signal that narrows the search.
    4. Satellites answer only the question they were pointed at: Remote sensing and satellite-based analysis are important, but different satellite tools answer different questions, and each needs a target. Engaging local communities is how the target is found.
    5. Almost every event came from an unknown place: Of over a dozen extreme events in the Himalayas over 10 years, almost all came from unknown places, the South Lhonak GLOF being the one known risk.
    6. No borrowed training data: Patterns are beginning to emerge, but no training dataset from the Alps or Norway can simply be transferred to the Himalayas, which have their own context and significant data scarcity and data sparsity.

    What monitoring triangle does the interview propose for India, Nepal and the Himalayas?

    1. Mapping is the baseline: The mapping exercise undertaken by India’s Home Ministry and space agencies to monitor glacial lakes and hazards is an absolute necessity. Nepal does not have the same level of resources. Some mapping has been done there, and it is not as comprehensive.
    2. Maps enable zoning; monitoring is the key: Once maps exist, hazard zoning and modelling can begin, but detection depends on continuous monitoring.
    3. Corner one, remote sensing: Remote sensing and satellite imagery form one part of the triangle.
    4. Corner two, fixed station networks: Hydromet (hydrological and meteorological) and seismic stations form the second.
    5. Corner three, localised monitoring through local government: Local governments, disaster managers and Community Disaster Management Committees can collect local data, report landslides and monitor impacts after storms.
    6. Localised monitoring through people immersed in the terrain: Yak herders and fishermen notice changes in rivers, glaciers and glacial lakes. Oral histories with elders reveal smaller avalanches, glacial-lake floods and other events that science has not recorded, helping identify potential hotspots.
    7. The combination is the detector: Combining the station network, remote sensing and localised monitoring gives a better chance of detecting changes and distinguishing the signal from the noise that tells you where to look.

    Challenges to Himalayan hazard monitoring

    1. Hydropower sited in hazard corridors without upstream sensing: Projects sit in narrow gorges below unstable ice and rock with no instrument between the source and the intake. Eg. The February 2021 Chamoli rock and ice avalanche from Ronti peak destroyed the Rishiganga and Tapovan-Vishnugad projects with no upstream warning.
      The Fix: Make a hazard chain assessment and ridge line sensors with satellite telemetry a condition of clearance for every Himalayan hydropower project.
    2. Instruments die with the event they are meant to detect: A sensor placed at the lake or in the channel is destroyed by the first surge and reports nothing. Eg. Monitoring equipment installed at South Lhonak lake in September 2023 was washed away in the October 2023 outburst that also breached the Teesta III dam at Chungthang.
      The Fix: Place redundant stations on high ground and at staggered distances downstream so at least one survives to trigger sirens.
    3. Cross-border flows carry no shared alert: The upstream country holds the first minutes of warning and no protocol obliges it to pass them on. Eg. India’s hydrological data sharing arrangement with China on the Brahmaputra lapsed in 2023.
      The Fix: Adopt a Hindu Kush Himalaya alert protocol through the International Centre for Integrated Mountain Development (ICIMOD) that pushes automatic upstream alerts to downstream disaster authorities within minutes.
    4. Warnings that never reach the last mile: A satellite detection is useless to a village asleep in a gorge with no siren and no signal. Eg. The Sikkim outburst struck after 10 pm on 3 October 2023 and reached the Teesta valley settlements in the dark.
      The Fix: Pair the National Disaster Management Authority’s Common Alerting Protocol based cell broadcast with battery-backed community sirens in every mapped downstream settlement.

    Conclusion

    India has the baseline map; Nepal has part of one. Neither has the monitoring triangle that turns a map into a warning. The unresolved gap is that detection still depends on knowing where to look, and the herders, fishermen and village committees who hold that knowledge are not yet wired into any station network. The test of the next monsoon is whether a single high mountain site with no red flag gets watched because a community reported it first.

    Back2Basics

    1. What it is: A sudden release of water from a lake formed by melting glaciers, held back by a natural dam of loose moraine debris or ice rather than bedrock.
    2. How it starts: An avalanche, rockfall or ice calving into the lake sends a displacement wave over the dam, or seepage erodes the moraine from within until it collapses.
    3. Why it is deadlier than a rain flood: The surge carries rock and sediment, arrives with minutes of warning, and can breach infrastructure far below the lake.
    4. India’s framework: The National Disaster Management Authority issued dedicated guidelines on GLOF and Landslide Lake Outburst Flood management in 2020.

  • Solution for stubble burning lies close to the farm

    Solution for stubble burning lies close to the farm

    Why in the News


    Punjab’s paddy harvesting season is approaching, reviving Delhi’s air-pollution concerns. The focus is shifting from banning stubble burning to creating profitable markets for parali and increasing farmers’ income.

    What is biochar?

    1. Definition: Biochar is a carbon-rich material produced by heating biomass under limited oxygen, so the carbon is retained as char rather than burnt away.
    2. Feedstock: It can be made from crop residues such as paddy, maize, cotton and mustard stalks.
    3. Yield: Roughly 100 kg of dry parali yields around 30 kg of char.
    4. Use in soil: Applied to soil, it improves water retention and nutrient-use efficiency and locks carbon away for a century.

    Why do farmers still burn after years of measures?

    1. Unchanged economics: Residue is bulky, the window before wheat sowing is narrow, and almost every alternative to burning carries a cost.
    2. Burning is quick and cheap: Alternatives involve cost, labour and uncertainty, so burning remains the rational choice at the field.
    3. Limits of enforcement and subsidy: Enforcement and machinery subsidies help, and behaviour changes only when the residue itself becomes valuable.

    What has changed in the economics of parali?

    1. From a cost to a price: Farmers in several locations were paying to have straw removed. Today in parts of Punjab the same straw fetches around Rs 1.5 to 2 per kg.
    2. Who is buying: Demand from power plants, compressed biogas (CBG) units and pellet manufacturers is slowly creating a market for what was treated as waste.
    3. The new question: If parali now has value, the issue is where that value should be created and how much can remain with the farmer.

    Why is biochar different from burning straw for energy?

    1. Carbon fate: Burning biomass as fuel recovers energy and returns much of its carbon to the atmosphere. Biochar applied to soil retains a significant share of the carbon and serves an agronomic purpose.
    2. Punjab’s need: The rice-wheat system is under stress from declining soil quality, intensive fertiliser use and groundwater depletion, and residue generated by the same system could improve its soils.

    Where is the value created, and who captures it?

    1. The processing location problem: Parali has to be collected, baled, stored and transported within the narrow window before wheat sowing. Long-distance transport of a bulky, relatively low-value material quickly eats into its economics.
    2. Farmer as raw material supplier: The farmer supplies the raw material, and most value addition happens after the biomass leaves the village.
    3. The biochar irony: A farmer supplies the straw, sees it processed elsewhere and later buys back a product made from biomass originating on farms like his.
    4. The chakki precedent: Wheat does not travel 100 km merely because flour requires machinery. The village chakki places processing close to where the commodity is produced and consumed.

    How would a village-scale biochar system work?

    1. Build-operate-transfer: A technology provider installs and operates the unit, trains local operators and ensures quality and emission standards. Over time the asset and the capability transfer to a farmer producer organisation (FPO), a self-help group (SHG) or a cooperative.
    2. Government’s role: The government provides standards, training, concessional finance and initial support rather than running thousands of units, and panchayats help with land and coordination.
    3. Farmer’s routine: Farmers bring straw to a nearby processing point much as they bring wheat to a flour mill. Some biochar returns to their fields and the rest is sold where markets exist.
    4. What changes: Raw straw travels less, value addition happens closer to the farmer, and villages are not left with subsidised machinery nobody knows how to operate.

    Challenges to village-scale biochar processing

    1. Emissions from small kilns: A poorly run pyrolysis unit releases methane, carbon monoxide and particulate matter, and so replaces one smoke source with another. Eg. The Kon-Tiki flame curtain kiln, the low-cost design most village pilots use, has no flue gas treatment.
      The Fix: Notify emission standards for small pyrolysis units under the Central Pollution Control Board and make the build-operate-transfer operator liable for them until handover.
    2. Carbon credit verification: Biochar earns carbon removal credits only where permanence is measured, and a village unit cannot measure it alone. Eg. The Puro.earth biochar methodology requires a hydrogen to organic carbon ratio below 0.7 as the test of permanence.
      The Fix: Aggregate village units under an FPO level registry with laboratory testing so that credits are pooled and sold at scale.
    3. Paddy straw is a poor feedstock on its own: Paddy straw carries a high silica content, so its char is ash heavy and lower in fixed carbon than wood char. Eg. Rice straw ash is largely silica, and the char inherits it.
      The Fix: Blend paddy straw with maize, cotton and mustard stalks across seasons so that a unit runs year round on a better mix.
    4. Competition from existing straw buyers: A village unit competes for the same straw as large plants that already pay for it. Eg. The Verbio compressed biogas plant at Lehragaga in Sangrur, Punjab, consumes about one lakh tonnes of paddy straw a year.
      The Fix: Site biochar units in blocks beyond the collection radius of existing CBG and pellet plants, using the State’s straw balance map.
    5. Window mismatch: Straw arrives in three weeks and a unit needs feedstock for months. Eg. Punjab’s paddy harvest runs through late October and wheat sowing closes by mid-November.
      The Fix: Subsidise baling and covered storage at the processing point under the crop residue scheme so that processing continues after the window closes.

    Conclusion

    The policy question on parali has moved from stopping a practice to locating a market, and the location decides who captures the value. Village-scale processing answers that question only if quality, emissions and offtake are secured before the technology provider exits. The next window is the October to November harvest. Whether any State pairs its residue management subsidies with village-level processing points is the thing to watch.

    Stubble Burning in India

    1. What it is: Stubble burning is the practice of setting fire to the straw residue left in fields after harvest, especially paddy, to clear the land quickly for the next sowing.
    2. Where and when: It is concentrated in Punjab, Haryana, Uttar Pradesh and the National Capital Region during the post-monsoon October to November window.
    3. Why it happens: The narrow gap between paddy harvest and wheat sowing pushes farmers toward the cheapest and fastest clearing method.
    4. Scale: Punjab alone generates about 20 million tonnes of paddy straw a year.

    Challenges in Stubble Burning

    1. Episodic air pollution: Burning sharply aggravates the Air Quality Index across the Indo-Gangetic Plain within days. Eg. In December 2025 Delhi’s AQI crossed 500 and over 150 flights were delayed.
      The Fix: Front-load machine deployment in the fortnight before harvest with block-level fire targets monitored by satellite.
    2. Soil degradation: Burning destroys beneficial soil microbes, nitrogen and organic carbon. Eg. Each tonne of burnt paddy straw loses about 5.5 kg of nitrogen, 2.3 kg of phosphorus and 25 kg of potassium.
      The Fix: Pay a per-acre incentive for in-situ incorporation with Happy Seeder or Super Seeder, verified by satellite.
    3. Meteorological trap: Winter temperature inversions and calm winds prevent dispersal and compound the damage. Eg. Delhi invoked Stage IV of the Graded Response Action Plan in November 2024 when the AQI crossed 450.
      The Fix: Time enforcement and straw collection to the weeks before inversions set in rather than to the pollution peak.
    4. Paddy-centric cropping in a water-stressed region: Free farm power and assured procurement lock Punjab into paddy. Eg. About three fourths of Punjab’s groundwater assessment units are over-exploited as per the Central Ground Water Board.
      The Fix: Offer a per-hectare diversification incentive for maize and pulses with assured procurement so that the residue problem shrinks at source.
    5. Penalty without a price: Enforcement fines farmers who have no cheaper alternative. Eg. Environmental compensation for burning was doubled in November 2024 to Rs 5,000 for under two acres, Rs 10,000 for two to five acres and Rs 30,000 above five acres.
      The Fix: Pair the penalty with a guaranteed straw purchase price at the block level so that not burning is the cheaper option.

  • All animals need equal consideration

    All animals need equal consideration

    Why in the News

    A division Bench of the Supreme Court has ordered the Keralam government to take custody of Raman, Keralam’s tallest elephant, in Jayakrishna Menon vs. Krishnankutty & Ors. The Bench observed that the court cannot remain a mute spectator in matters concerning animals and that their wellbeing is of “paramount importance”. It held that it would fail in its duty towards “voiceless animals” if it ignored the elephant’s continued use for temple activities after its own prohibition. The order stands in contrast with Re: City Hounded by Strays, Kids Pay Price (2026). There a three judge Bench adopted a much narrower interpretation of the law. That reading led to the removal of large numbers of dogs from public institutions. The divergence raises the question whether Indian animal law grades animals by their value to humans rather than by their capacity to suffer.

    What is equal consideration?

    1. The principle: Framed by moral philosopher Peter Singer, equal consideration holds that the basic principle of equality does not require equal or identical treatment; it requires that the interests of each being be weighed equally.
    2. Who qualifies: Every being that has interests, some subjective awareness, or the capacity to feel pleasure or pain.
    3. Different treatment can follow: Equal consideration for different beings can lead to different treatment and different rights, because their needs differ.

    What questions does the differential treatment of two animals raise?

    1. The court’s own premise: The elephant order implicitly acknowledges an animal’s propensity to suffer and the need to ensure its wellbeing.
    2. One elephant against lakhs of dogs: Why one elephant’s wellbeing is of paramount importance and the welfare of lakhs of street dogs is disregarded.
    3. One institution, two approaches: How the same institution adopts two contrasting, if not contradictory, approaches to issues involving similar moral considerations.
    4. Whether courts should decide at all: Whether the judiciary is the best positioned institution to decide cases that seal the fate of animals, for better or for worse.

    Do the differences between the two animals justify different consideration?

    1. The elephant’s legal standing: The Indian elephant is a charismatic animal, listed as Endangered on the International Union for Conservation of Nature (IUCN) Red List, and explicitly protected under the Wild Life (Protection) Act, 1972.
    2. The street dog’s legal standing: The street dog is legally perceived as a problem that needs to be tackled.
    3. Different relationships with humans: One is expected to live in the wild away from human habitation. The other shares public spaces, requiring humans to learn to coexist in shared spaces.
    4. The test: Whether these differences are significant enough to attract completely different moral and legal considerations.
    5. What is actually missing: In the two judgments the absence of equal consideration itself drives the differential treatment. Equal consideration would require an assessment of the needs of each animal and then the determination of a course of action.

    Why does the remedy lie with Parliament rather than the courts?

    1. Anthropocentric bias in both statutes: The Wild Life (Protection) Act, 1972 for elephants and the Prevention of Cruelty to Animals Act, 1960 for street dogs evaluate the worth of animals by their value to humans. That valuation determines the nature and level of protection each animal receives.
    2. A gap in legislative guidance: Two cases involving different animals produced contrasting approaches from the same court. That exposes the absence of a legislative standard for animal well-being across legal categories.
    3. The Swiss model, cited in passing: The Swiss Constitution ensures the well-being of animals and also protects animal dignity, granting animals an inherent worth.
    4. Parliament’s responsibility: Parliament should extend protection to every being worthy of moral consideration, through a legislative foundation that provides moral consideration to all animals and pathways for ethical coexistence.

    Challenges to an equal consideration standard in Indian animal law

    1. Fragmented statutes: The same act of harm is governed by different laws depending on the animal’s legal category, so no single test of suffering applies. Eg. Street dogs fall under the Animal Birth Control Rules, 2023 made under the cruelty law, and elephants fall under Schedule I of the wildlife law.
      The Fix: Enact a single animal welfare code with a sentience-based standard that applies across categories, with the wildlife schedules layered on top for conservation purposes.
    2. Nominal penalties: Section 11 of the Prevention of Cruelty to Animals Act, 1960 punishes a first cruelty offence with a fine of Rs 10 to Rs 50, unchanged since enactment. Eg. The draft Prevention of Cruelty to Animals (Amendment) Bill, 2022 proposed fines up to Rs 75,000 and imprisonment for gruesome cruelty and has not been introduced in Parliament.
      The Fix: Introduce the amendment Bill with graded penalties and a statutory definition of sentience.
    3. Unsettled legal status of animals: High Courts and the Supreme Court have taken different positions on whether animals are legal persons, so lower courts have no stable rule. Eg. The Uttarakhand High Court in Narayan Dutt Bhatt v. Union of India (2018) and the Punjab and Haryana High Court in Karnail Singh v. State of Haryana (2019) declared animals legal persons, a status no Supreme Court ruling has endorsed.
      The Fix: Settle the legal status of animals in statute rather than leaving it to divergent judicial declarations.
    4. No enforcement arm: The Animal Welfare Board of India is advisory, and district level societies exist on paper. Eg. The Prevention of Cruelty to Animals (Establishment and Regulation of Societies for Prevention of Cruelty to Animals) Rules, 2001 require a society in every district, and many districts have none.
      The Fix: Fund district societies from State budgets with mandated veterinary and inspector staffing and a reporting line to the State Animal Welfare Board.

    Conclusion

    The two rulings leave a tension unresolved. Indian animal law protects by category, endangered species on one side and nuisance animals on the other, and the capacity to suffer sits on neither side of that line. A court can decide the case before it; it cannot write a standard that applies to every animal. The thing to watch is whether Parliament takes up the pending amendment to the cruelty law and whether it writes sentience, rather than human utility, into the test.

    Animal Welfare Law in India

    1. What it covers: Statutory protection of animals from cruelty and of wild species from harm, spread across a cruelty statute, a wildlife statute and subordinate rules for specific uses such as transport, slaughter, performance and experiments.
    2. Two regimes: The cruelty law applies to any animal, domestic, captive or stray. The wildlife law protects species by schedule, and the Wild Life (Protection) Amendment Act, 2022 reduced the schedules from six to four.
    3. Institutions: The Animal Welfare Board of India (statutory since 1962), the Committee for Control and Supervision of Experiments on Animals for laboratory use, and the National Board for Wildlife for protected species.
    4. Scale: India holds about 60 percent of the world’s Asian elephants, with 29,964 counted in the 2017 synchronised census, and the 20th Livestock Census (2019) counted 1.53 crore stray dogs.

    Challenges in Animal Welfare

    1. Rabies from an unmanaged stray population: Sterilisation and vaccination have not reached the coverage that stops transmission. Eg. India accounts for about 36 percent of global rabies deaths as per the World Health Organization.
      The Fix: Fund local bodies to reach 70 percent vaccination coverage of the dog population in each ward, since transmission breaks at that threshold.
    2. Captive elephants at festivals: Parading in heat, crowds and noise causes injury and deaths of animals and people. Eg. The Kerala High Court’s 2024 guidelines on distance and rest norms for parading elephants were contested before the Supreme Court by festival organisers.
      The Fix: Enforce microchip registration and the 2024 transfer rules so that every captive elephant has a traceable owner accountable for its welfare.
    3. Culture against welfare: Traditional events with animals are permitted by State amendments to the cruelty law. Eg. A five judge Bench in Animal Welfare Board of India v. Union of India (2023) upheld Tamil Nadu’s Jallikattu amendment.
      The Fix: Codify measurable welfare conditions for each permitted event under the Performing Animals rules, with veterinary supervision as a licence condition.
    4. Regulation of livestock trade: Welfare rules for animal markets have collapsed under political contest. Eg. The Prevention of Cruelty to Animals (Regulation of Livestock Markets) Rules, 2017 were stayed by the Supreme Court and withdrawn in 2018.
      The Fix: Re-notify market rules confined to welfare conditions such as water, shade and transport limits, without conditions on the purpose of sale.
