  • Why key to coconut cultivation today is sustainability, not productivity

    Why in the News?

    The Union Budget 2026-27 announced a Coconut Promotion Scheme focused on raising productivity through high-yielding varieties. This comes despite projections of a 1.6-2.1°C temperature rise by 2050 (up to 3.2°C by 2070), which may render large parts of peninsular India less suitable for coconut cultivation. The issue signals a shift from yield expansion to climate-resilient sustainability in plantation policy.

    What is the Status of Coconut Cultivation in India?

    1. Global Position: India is the world’s largest producer and consumer of coconuts.
    2. Productivity Levels: Per-palm productivity in India exceeds that of Sri Lanka, the Philippines, and Indonesia.
    3. Geographical Spread: Major cultivation concentrated in Kerala, coastal Karnataka, and Tamil Nadu, with expansion into Gujarat, Assam, and other non-traditional regions.
    4. Western Coast Belt: Kerala, coastal Karnataka, and western Tamil Nadu remain core high-temperature resilience zones.
    5. Emerging Vulnerabilities: Interior Karnataka, Andhra Pradesh, Tamil Nadu, and parts of the east coast face projected climatic unsuitability.
    6. Price Trend: Domestic coconut prices have remained higher than international prices since 2024, affecting competitiveness.

    What Are the Major Coconut Policies and Schemes in India?

    1. Coconut Development Board (CDB) Schemes
      1. Replanting and Rejuvenation: Replaces senile and diseased palms.
      2. Area Expansion: Promotes cultivation in non-traditional states.
      3. Productivity Support: Distributes improved and hybrid seedlings.
      4. Market Linkages: Facilitates branding and export promotion.
    2. Coconut Promotion Scheme (2026-27)
      1. Garden Revitalisation: Targets old and unproductive plantations.
      2. High-Yield Varieties: Enhances productivity through improved planting material.
      3. Coastal Expansion: Supports new plantations in coastal regions.
    3. Technology Mission on Coconut
      1. Integrated Approach: Covers production, processing, and marketing.
      2. Value Addition: Supports coconut oil, desiccated coconut, and coir units.
    4. Cluster Development Programme (NHB)
      1. Cluster-Based Development: Strengthens aggregation, processing, and market access.
    5. Support under National Missions
      1. MIDH/NMSA Linkages: Provides irrigation, sustainability, and infrastructure support.

    Why is Productivity-Centric Policy Inadequate for Coconut Cultivation?

    1. Yield Plateau: India already records higher per-palm productivity than Sri Lanka, the Philippines, and Indonesia. Further yield push offers limited marginal gains.
    2. Price Distortion: Domestic coconut prices remain above international prices since 2024, limiting export competitiveness.
    3. Climate Risk Escalation: Temperature rise of 1.6-2.1°C by 2050 and up to 3.2°C by 2070 increases vapour pressure deficit and drought stress.
    4. Disease Vulnerability: Root wilt disease has devastated districts like Alappuzha and Pollachi.
    5. Regional Unsuitability: Interior peninsular regions may become climatically unsuitable in coming decades.

    How Does Climate Change Threaten Coconut Geography in India?

    1. Temperature Sensitivity: Coconut is sensitive to heat stress during flowering and nut development stages.
    2. Western Ghats Buffer: Current cultivation belt in Kerala, coastal Karnataka, and western Tamil Nadu benefits from moderated temperatures.
    3. Interior Risk Zones: Karnataka, Andhra Pradesh, and parts of Tamil Nadu show vulnerability under climate projections.
    4. East Coast Stress: Cyclones and salinity intrusion increase risk in eastern coastal regions.
    5. Vapour Pressure Deficit Rise: Intensifies moisture stress even when rainfall levels appear stable.

    Why Must the Scheme Prioritise Climate-Resilient Varieties?

    1. Heat-Tolerant Genotypes: Ensures long-term viability under rising temperature regimes.
    2. Drought-Resistant Varieties: Supports survival under irregular rainfall and groundwater depletion
    3. Disease-Resistant Strains: Reduces root wilt and pathogen vulnerability.
    4. Regional Customisation: East coast requires climate-resilient varieties; west coast requires wilt-tolerant strains.
    5. Research Integration: State universities and ICAR institutions possess breeding capacity for resilient genotypes.

    What Structural and Institutional Failures Limit Current Schemes?

    1. Input Subsidy Bias: Focus remains on free biological inputs rather than structural farm transformation.
    2. Low-Quality Inputs: Distribution-based schemes often reduce soil microbial viability.
    3. Farmer Producer Organisation (FPO) Exclusion: High compliance norms prevent meaningful farmer producer organisation participation.
    4. Capital Subsidy Fragmentation: Coconut Development Board (CDB) offers 25% capital subsidy for value addition, but variation across schemes causes confusion.
    5. Implementation Gaps: Cluster Development Programme of NHB remains under-implemented due to investment barriers.

    Why Are Cooperative and Cluster Models Critical?

    Cooperative and Cluster Models are institutional mechanisms that aggregate farmers geographically or organisationally to enable collective production, processing, value addition, and marketing, thereby ensuring scale efficiency, bargaining power, and income stability.

    1. Vertical Integration: Links production, value addition, and marketing.
    2. Cooperative Precedent: Models like AMUL demonstrate scale-based efficiency and farmer ownership.
    3. Processing Stability: Encourages long-duration procurement and price stabilisation.
    4. Market Diversification: Expands into coconut oil, tender coconut, desiccated coconut, coir products.
    5. Risk Sharing Mechanism: Reduces individual farmer exposure to climate and price shocks.

    How Should Policy Shift from Expansion to Sustainability?

    1. Direct Benefit Transfers: Empowers farmer-led decision-making on irrigation, soil amendments, labour.
    2. Small Pilot Projects: Generates ground-level feedback before scaling.
    3. Climate Mapping: Aligns plantation zones with projected climate suitability.
    4. Integrated Funding: Aligns Coconut Promotion Scheme with Cluster Development Programme.
    5. Institutional Voice Inclusion: Incorporates farmer consultation to reflect ground realities.

    Conclusion

    Productivity enhancement alone cannot secure the future of coconut cultivation under rising climate stress. Policy design must shift from input subsidies and area expansion to climate-resilient varieties, water-use efficiency, institutional integration, and cooperative value-chain development. A sustainability-centred framework is essential to ensure long-term farmer income stability and agro-ecological viability.

  • [13th February 2026] The Hindu OpED: Farmers’ pulse: On India and its demand for pulses

    PYQ Relevance

    [UPSC 2017] Mention the advantages of the cultivation of pulses because of which the year 2016 was declared as the International year of Pulses by the United Nations.

    Linkage: It links to the pulses debate as it highlights their nutritional, ecological, and income-support role, strengthening arguments for procurement reform and crop diversification.

    Mentor’s Comment

    Pulses policy reflects a structural tension between consumer price stabilization and farmer income security. Weak procurement architecture, import dependence, and trade commitments intersect with federal politics and food security imperatives.

    Why in the News?

    India’s pulses policy is back in focus after reports of possible import commitments under a trade deal with the United States. This appears to clash with the government’s Mission for Aatmanirbharta in Pulses, raising fresh concerns among farmers about the gap between self-reliance goals and trade decisions.

    Why Are Pulses Crucial to India’s Food and Farm Economy?

    1. Protein Dependence: Pulses supply nearly 25% of non-cereal protein intake.
    2. Livelihood Base: Around five crore farmers depend on pulse cultivation.
    3. Persistent Demand Gap: Production ~2.5 crore tonnes; demand ~3 crore tonnes; imports fill deficit.
    4. Food Security Linkage: Dependence on imports exposes vulnerability to global price fluctuations.

    How Do Imports Create Immediate Market Distortions?

    1. Centralized Decision Impact: A single central decision to import can immediately lower domestic prices.
    2. Household Spending Relief: Imports reduce consumer expenditure when supply is tight.
    3. Farmer Income Shock: Price depression directly hurts domestic producers.
    4. Market Absorption Constraint: Domestic markets cannot always absorb “extra” supply, worsening price collapse.
    5. Political Sensitivity: Trade commitments perceived as favouring foreign producers revive post-2020 protest anxieties.

    Why Is the Procurement Regime Considered Structurally Weak?

    1. Limited Coverage: Procurement under the Price Support Scheme ranged between 2.9%-12.4% (2019-24).
    2. MSP Without Guarantee: Absence of reliable procurement undermines MSP credibility compared to rice and wheat.
    3. Organised Neglect: Weak procurement mechanisms, cereal bias, and institutional design collectively marginalize pulses.
    4. Distress Sales: Inadequate procurement centres force farmers to sell below MSP to private traders.
    5. Investment Disincentive: Uncertain returns discourage productivity-enhancing investments.

    What Structural Constraints Affect Pulse Cultivation?

    1. Rain-fed Cultivation: Pulses largely grown in rain-fed regions, increasing climate risk.
    2. Lower Yields: Productivity remains below international competitors.
    3. Underinvestment Cycle: Weak price assurance leads to low investment, perpetuating low yields.

    What Does the Mission for Aatmanirbharta in Pulses Seek to Achieve?

    1. Financial Allocation: â‚č11,440 crore outlay.
    2. Area Expansion: Target of 310 lakh hectares.
    3. Production Goal: 350 lakh tonnes by 2030-31.
    4. Strategic Objective: Reduce import dependence and achieve self-sufficiency.
    5. Credibility Challenge: Past unfulfilled promises create farmer scepticism.
    6. Policy Contradiction Risk: Import commitments contradict mission objectives.

    Why Does This Issue Trigger Political Sensitivity?

    1. Farm Protest Context: Post 2020-21 protests, trade and agri-reform decisions face scrutiny.
    2. Federal Dimension: Central trade decisions affect state-level agriculture.
    3. Trust Deficit: Perception of favouring foreign producers undermines domestic policy legitimacy.
    4. Food Security Vulnerability: Continued import dependence sustains long-term strategic risk.

    Way Forward

    1. Stronger Procurement: Expand procurement centres in pulse-growing areas to ensure MSP reaches farmers and reduce distress sales.
    2. MSP Credibility: Ensure timely and predictable procurement to build farmer confidence and encourage investment.
    3. Stable Import Policy: Align imports with domestic production cycles to prevent sudden price crashes.
    4. Higher Productivity: Promote improved seeds, irrigation support, and climate-resilient varieties to raise yields.
    5. Crop Diversification: Reduce policy bias toward rice and wheat and incentivise pulses through procurement and subsidies.

    Conclusion

    Pulses policy reflects the tension between consumer price stability and farmer income security. Import dependence without strong procurement weakens domestic incentives and deepens vulnerability. Long-term food security requires credible MSP implementation, higher productivity, and a trade policy aligned with self-reliance goals.

  • India’s record rice output comes with challenges

    Why in the News?

    India’s rice production has reached its highest-ever level, accompanied by excess central stocks far beyond food security requirements. Rice stocks crossed 63.06 million tonnes in January 2026, nearly three times the buffer norm, signalling structural imbalance rather than temporary surplus. This marks a sharp contrast from earlier decades when production increases were aimed at eliminating shortages and stabilising prices.

    How Has Rice Production Expanded Over Time?

    1. Production Growth: Increased from 40 million tonnes in 1969-70 to 150 million tonnes in 2024-25, reflecting sustained expansion rather than episodic growth.
    2. Area Expansion: Acreage rose from 37.67 million hectares to 51.42 million hectares, indicating reliance on area expansion in addition to yield gains.
    3. Yield Improvement: Productivity reached 3.28 tonnes per hectare, though with wide inter-state variation.
    4. Regional Concentration: Punjab, Haryana, Andhra Pradesh, Telangana, Uttar Pradesh, Chhattisgarh, Odisha, and West Bengal dominate output.

    Why Are Central Rice Stocks Excessive?

    1. Procurement Dominance: Nearly 56.1% of total rice procurement originates from Punjab, Haryana, Odisha, and Chhattisgarh.
    2. MSP Incentives: Assured MSP procurement has encouraged continuous paddy cultivation irrespective of demand.
    3. Food Corporation of India Storage: Rice stocks stood at 63.06 million tonnes, exceeding buffer and strategic reserve norms.
    4. Fiscal Burden: FCI storage costs exceed â‚č3 per kg per year, excluding power, fertiliser, and irrigation subsidies.

    What Role Does Government Policy Play in Paddy Dominance?

    1. Minimum Support Price: MSP for common paddy pegged at â‚č2,300 per quintal, ensuring price certainty.
    2. Procurement Bias: Rice enjoys stronger procurement assurance than most alternative crops.
    3. Power Subsidies: Free or subsidised electricity lowers irrigation costs, reinforcing paddy cultivation.
    4. Risk Aversion: Farmers prefer paddy due to assured returns over diversified crops with uncertain markets.

    Why Is Paddy Cultivation Environmentally Unsustainable?

    1. Water Intensity: Paddy requires 3,000-5,000 litres of water per kg, stressing water resources.
    2. Groundwater Depletion: Excessive withdrawal in Punjab has led to severe groundwater decline.
    3. Regional Unsuitability: Paddy expansion in water-stressed states contradicts agro-climatic suitability.
    4. Environmental Stress: Continuous monocropping degrades soil health and water tables.

    Why Has Crop Diversification Not Taken Off?

    1. Economic Risk: Alternative crops offer lower or uncertain returns compared to paddy.
    2. Market Absence: Limited procurement and price support for pulses, oilseeds, and millets.
    3. Institutional Inertia: Existing procurement and subsidy architecture remains rice-centric.
    4. Behavioural Lock-in: Decades of MSP-driven cultivation patterns discourage experimentation.

    What Measures Are Being Considered for Diversification?

    1. Direct Incentives: Proposal to compensate farmers who shift away from paddy.
    2. Income Replacement: Incentive amounts aimed at bridging the income gap from paddy cultivation.
    3. Target Regions: Focus on states with declining groundwater and paddy over-concentration.
    4. Strategic Shift: Emphasis on conserving water alongside nutritional security.

    Conclusion

    India’s rice production milestone underscores the success of assured procurement and productivity gains. However, excess stocks, rising fiscal costs, and groundwater depletion reveal structural imbalances. Sustaining food security now requires recalibrating incentives, correcting procurement bias, and aligning cropping patterns with ecological realities rather than expanding output indefinitely.

    PYQ Relevance

    [UPSC 2020] What are the major factors responsible for making rice-wheat system a success? In spite of this success how has this system become bane in India?

    Linkage: The rice-wheat system succeeded due to assured MSP procurement, irrigation expansion, and Green Revolution technologies, ensuring food security. However, it has become a bane due to groundwater depletion, soil stress, fiscal burden, and poor crop diversification, making it a core GS-III sustainability issue.

  • The weed threat to mustard, and need for new solutions

    Introduction

    Mustard is India’s largest indigenous edible oil source, cultivated across nearly nine million hectares, primarily in Rajasthan, Uttar Pradesh, Madhya Pradesh, Haryana, and West Bengal. The crop is increasingly threatened by Orobanche aegyptiaca, a root-parasitic weed that attaches to mustard roots and extracts nutrients, water, and carbon. The infestation has led to severe yield losses, stagnation in productivity, and renewed dependence on edible oil imports despite policy emphasis on self-reliance.

    Why in the News

    Orobanche has emerged as the number one “hidden threat” to mustard in major producing states, particularly Haryana and Rajasthan. The infestation has intensified uniformly across fields, even where no visible weed shoots appear initially. Yield losses have become severe, with farmers reporting declines from 9 quintals per acre to 6 quintals, despite normal weather and irrigation. This represents a sharp contrast to earlier years when mustard yields remained stable under similar conditions. The problem directly affects India’s strategy to curb edible oil imports, which stood at $15.9 billion in 2023-24 and $18.3 billion in 2024-25, making the issue macro-economically significant.

    Why is mustard critical to India’s edible oil economy?

    1. Dominant Indigenous Crop: Accounts for over 40 million tonnes of indigenous edible oil output in 2023-24 and 2024-25, the highest among domestic oilseeds.
    2. Import Substitution Role: Identified as the primary crop for yield improvement to reduce 16 million tonnes of annual edible oil imports.
    3. Farmer Dependence: Traditionally grown on three-fourths of irrigated land in parts of Haryana due to low input requirements.

    What is Orobanche aegyptiaca and why is it dangerous?

    1. Parasitic Nature: Attaches underground to mustard roots, extracting nutrients and water, causing wilting and stunted growth.
    2. Hidden Infestation: Damage occurs before shoots appear above ground, delaying farmer response.
    3. Seed Proliferation: A single plant produces 40-45 flowers, each bearing 4,000-5,000 seeds, viable for up to 20 years in soil.
    4. Rapid Spread: Disperses through wind, water, and irrigation channels, creating dense seed banks.

    Why has the infestation intensified in recent years?

    1. Cropping Pattern Rigidity: Repeated cultivation of mustard on the same land enhances parasite density.
    2. Irrigation Practices: First irrigation at 25-30 days after sowing creates ideal soil moisture for Orobanche germination.
    3. Climate Suitability: Moist soils followed by underground establishment accelerate attachment to roots.
    4. Delayed Visibility: By the time shoots emerge, yield damage is irreversible.

    Why are existing herbicide options ineffective?

    1. Non-Selective Action: Glyphosate inhibits EPSPS enzyme in both crops and weeds, preventing selective control.
    2. Dosage Constraints: Recommended spray levels are too low for absorption by Orobanche.
    3. Crop Damage Risk: Stronger herbicides like glufosinate, paraquat, imazapyr cannot be used on normal mustard.
    4. Control Failure: Current chemical strategies fail to distinguish between host and parasite.

    How can herbicide-resistant mustard hybrids change outcomes?

    1. Technological Breakthrough: Introduction of imidazolinone-resistant mustard hybrid ‘Pioneer 45S42CL’.
    2. Selective Weed Control: Enables use of imazapyr and imazapic to kill Orobanche without harming mustard.
    3. Field Evidence: Two sprays covering two acres cost â‚č3,150, significantly lower than yield losses.
    4. Farmer Adoption: Hybrid sold in 700-gram packs with bundled herbicide, showing positive early results.

    What are the long-term scientific and policy responses underway

    1. Genetic Solutions: Development of GM mustard lines containing ‘cp4 epsps’ and double-mutant ‘als’ genes.
    2. Resistance Spectrum: Enables tolerance to glyphosate, imidazolinones, and sulfonylureas.
    3. Seed Bank Management: Emphasis on preventing early emergence to reduce soil seed viability.
    4. Institutional Research: Ongoing work at the Centre for Genetic Manipulation of Crop Plants, Delhi University.

    Conclusion

    The Orobanche infestation has transformed mustard cultivation from a low-risk crop into a high-uncertainty enterprise. Addressing this challenge is essential not only for farmer incomes but also for India’s edible oil security strategy. Herbicide-resistant hybrids and genetic interventions represent critical pathways to restoring productivity and reducing import dependence.

    PYQ Relevance

    [UPSC 2017] What are the major reasons for declining rice and wheat yield in the cropping system? How crop diversification is helpful to stabilise the yield of the crops in the system?

    Linkage: The rice-wheat system question reflects UPSC’s focus on yield stagnation due to monocropping and biological stress. This pattern is equally visible in mustard through Orobanche infestation. Mustard, like rice-wheat, shows that repeated cropping without diversification increases pest and weed pressure, making crop diversification critical.

  • How rice farmers can cut methane and make money off it

    Introduction

    Rice cultivation traditionally relies on continuous flooding, creating anaerobic soil conditions conducive to methane-producing bacteria. Given that over 86% of Indian farmers are small and marginal, scalable, low-cost mitigation practices are essential. Alternate Wetting and Drying (AWD) comes across as a practical solution that reduces emissions without yield loss, supported by empirical data from Telangana, Andhra Pradesh, Odisha, and Tamil Nadu.

    Why in the News?

    Paddy cultivation contributes 28% of global methane emissions, with methane having 28 times the global warming potential of CO₂ over 100 years. The article highlights a first-of-its-kind, farmer-level implementation in India where Alternate Wetting and Drying (AWD) reduced methane emissions while enabling farmers to earn carbon credits. Unlike earlier mitigation efforts focused only on productivity, this approach integrates climate finance, water conservation, and income generation, marking a structural shift in rice farming practices.

    Why Does Traditional Paddy Cultivation Produce High Methane Emissions?

    1. Continuous Flooding: Maintains 4-5 cm water depth for the first 65 days of the crop cycle.
    2. Anaerobic Conditions: Support methanogenic microbes that decompose organic matter.
    3. Emission Intensity: Methane is 28 times more potent than CO₂ in warming potential.
    4. Global Impact: Paddy cultivation accounts for 28% of global methane emissions.

    What Is Alternate Wetting and Drying (AWD)?

    1. Irrigation Technique: Periodic drying of fields instead of continuous flooding.
    2. Operational Threshold: Irrigation resumes when water level falls to 15 cm below soil surface.
    3. Adoption Window: Implemented after first 20 days of transplantation.
    4. Institutional Support: Promoted by International Rice Research Institute (IRRI).

    How Does AWD Reduce Methane Emissions Without Yield Loss?

    1. Aeration of Soil: Disrupts methane-producing microbial activity.
    2. Water Savings: Reduces irrigation requirement significantly.
    3. Yield Stability: No statistically significant reduction in grain output.
    4. Ancillary Benefits: Lower weed pressure and improved nutrient efficiency.

    What Evidence Supports the Effectiveness of AWD in India?

    1. Field Study: Conducted across 30 sites in Telangana and Andhra Pradesh.
    2. Emission Reduction: Methane emissions reduced by 20-40%.
    3. Water Use: Comparable decline in irrigation water requirement.
    4. Scalability: Validated across varied agro-climatic conditions.

    How Are Farmers Monetising Methane Reduction?

    1. Measurement: Acrylic chambers used to quantify methane emissions.
    2. Verification: Samples analysed in accredited laboratories.
    3. Carbon Credits: 1 carbon credit = 1 tonne CO₂ equivalent.
    4. Earnings: â‚č1,300-â‚č7,000 per farmer per season depending on region.
    5. Aggregation Model: Credits pooled and sold to international buyers.

    What Institutional Models Are Enabling This Transition?

    1. Climate Tech Intermediaries: Facilitate monitoring, reporting, and verification (MRV).
    2. Carbon Markets: Buyers include energy-intensive global corporations.
    3. Corporate Partnerships: Shell Energy India supported AWD adoption.
    4. Scale: Over 12,000 farmers across 13 states integrated.

    Conclusion

    The article demonstrates that methane mitigation in rice farming is technically feasible, economically viable, and scalable. By linking irrigation practices with carbon markets, AWD represents a paradigm shift where climate action strengthens farm incomes rather than constraining them.

  • India’s status as world’s rice leader augurs a water crisis

    Introduction

    Rice production has expanded sharply due to assured procurement, rising subsidies, and export demand. However, groundwater-dependent irrigation has become the dominant mode in northern India. Despite strong monsoons in recent years, extraction rates exceed natural recharge. Government classification of aquifers as “over-exploited” or “critical” signals a structural imbalance between agricultural policy and water resource sustainability.

    Why in the News

    India overtook China to become the world’s largest rice producer in 2023, exporting nearly double the quantity compared to the past decade and producing over 140 million tonnes of rice. While this achievement was politically and economically celebrated, it has intensified groundwater extraction in Punjab and Haryana. Borewell depths have increased from 30-40 feet to 80-200 feet, indicating rapid aquifer depletion. Rice cultivation in India consumes 3,000-4,000 litres of water per kg, 20-60% higher than the global average, turning agricultural success into a water sustainability concern of national scale.

    How did India become the world’s largest rice producer?

    1. Production Expansion: Annual rice output exceeded 140 million tonnes, surpassing China in 2023.
    2. Export Growth: Rice exports nearly doubled in the past decade due to global demand and domestic surplus.
    3. Policy Support: Minimum Support Price (MSP) assurance ensured farmer preference for rice cultivation.

    Why is rice cultivation intensifying groundwater stress?

    1. High Water Requirement: Producing one kilogram of rice requires 3,000-4,000 litres of water, exceeding global norms by 20-60%.
    2. Groundwater Dependence: Punjab and Haryana rice farmers primarily rely on borewell irrigation.
    3. Aquifer Depletion: Groundwater levels declined from 30-40 feet to 80-200 feet, indicating unsustainable extraction.

    What role do subsidies play in water over-extraction?

    1. Electricity Subsidies: Free or low-cost power encourages excessive pumping of groundwater.
    2. Price Incentives: Rice prices increased by ~70% over the past decade, reinforcing crop preference.
    3. Input Distortion: Subsidies discourage transition to less water-intensive crops.

    Why are Punjab and Haryana particularly vulnerable?

    1. Irrigation Pattern: Dominant reliance on groundwater over surface irrigation systems.
    2. Weak Monsoon Resilience: Despite strong rainfall, extraction continues beyond recharge capacity.
    3. Critical Classification: Aquifers in both states fall under “over-exploited” or “critical” categories.

    How does groundwater stress threaten food security?

    1. Farmer Costs: Deeper borewells require higher capital and energy inputs.
    2. Production Risk: Aquifer depletion increases vulnerability to weak monsoons.
    3. Systemic Stress: India produces more rice than domestic requirements, amplifying water stress without proportional food security gains.

    What corrective signals are emerging?

    1. Crop Diversification Incentives: Haryana introduced â‚č17,500 per hectare subsidy for switching to less water-intensive crops.
    2. Policy Limitation: Incentives are seasonal and lack long-term assurance.
    3. Institutional Recognition: Government data acknowledges unsustainable groundwater extraction trends.

    Way Forward

    1. Crop Diversification
      1. Shift Incentivisation: Expands cultivation of less water-intensive crops such as pulses and oilseeds through multi-year income assurance.
      2. Procurement Reform: Aligns MSP and assured procurement with water-efficient cropping patterns.
    2. Rationalisation of Subsidies
      1. Power Pricing: Reduces indiscriminate groundwater pumping by restructuring free electricity for agriculture.
      2. Input Targeting: Replaces universal subsidies with direct income support decoupled from water use.
    3. Water-Efficient Irrigation
      1. Micro-Irrigation Expansion: Enhances adoption of drip and sprinkler systems to improve water productivity.
      2. Alternate Wetting and Drying (AWD): Reduces water use in paddy cultivation without yield loss.
    4. Groundwater Governance
      1. Aquifer Management: Strengthens block-level monitoring and annual recharge-extraction audits.
      2. Regulatory Enforcement: Restricts borewell depth expansion in over-exploited zones.
    5. Export Rationalisation
      1. Water Footprint Accounting: Integrates virtual water costs into export policy decisions.
      2. Surplus Management: Aligns export volumes with regional water availability.

    Conclusion

    India’s rise as the world’s largest rice producer reflects policy certainty, farmer responsiveness, and export competitiveness. However, the same policy framework has accelerated groundwater depletion in key agrarian states. Without reorienting incentives toward water-efficient agriculture, food security gains risk becoming ecologically unsustainable. Long-term agricultural resilience requires aligning production, procurement, and irrigation policy with groundwater realities rather than output maximisation alone.

  • Reforming the fertiliser subsidy demands political courage, offers high rewards

    Introduction

    India’s fertiliser subsidy, the second-largest subsidy after food, has expanded rapidly due to rising global energy prices, import dependence, and skewed pricing policies. In 2024-25, the subsidy is estimated to touch nearly â‚č2 lakh crore, with projections of â‚č2.5 lakh crore in FY26. The article argues not for withdrawal, but for reorientation of subsidies to correct price signals, improve nutrient balance, and enhance productivity while protecting farmers’ incomes.

    Why Fertiliser Subsidy Reform Is Back in Focus

    1. Fiscal Expansion: Fertiliser subsidy projected at ~â‚č2.5 lakh crore in FY26, compared to â‚č1.37 lakh crore allocated to agriculture and farmers’ welfare.
    2. Policy Asymmetry: Urea prices remain fixed and among the cheapest globally, while DAP and MOP prices are decontrolled.
    3. Macroeconomic Risk: Heavy import dependence, ~78% for natural gas, ~90% for phosphatic fertilisers, and near-total dependence for potash, exposes India to global commodity shocks.
    4. Structural Distortion: Price controls undercut the Nutrient-Based Subsidy (NBS) regime introduced in 2010.
    5. Reform Window: Stable growth and low inflation provide a favourable macroeconomic context for politically difficult reforms.

    How Price Controls Have Distorted Nutrient Use

    1. Urea Price Fixation: Urea sold at a fixed price of ~â‚č242 per 45-kg bag encourages excessive nitrogen use.
    2. NBS Design Flaw: Subsidy linked to nutrient content for P and K, but not applied uniformly to urea.
    3. Skewed Consumption: Farmers over-apply nitrogen while under-applying phosphorus and potassium.
    4. N:P:K Ratio Collapse: National ratio deteriorated to ~10.9:4:1 against the recommended 4:2:1.
    5. State-Level Distortion: Punjab applies ~61% more nitrogen than recommended, underuses potassium by ~89%, and phosphorus by ~8%.

    What Data Reveal About Productivity Outcomes

    1. China Comparison:
      1. Fertiliser use: ~373 kg/ha (China) vs ~182 kg/ha (India).
      2. N:P:K ratio: ~2.6:1.1:1 (China) vs ~10.9:4:1 (India).
      3. Agri-GVA: ~$1.27 trillion (China) vs ~$0.63 trillion (India).
    2. Land Productivity Gap: China generates double India’s agri-GVA despite similar cropped area.
    3. Yield Plateauing: Excess nitrogen creates “lush green fields” but fails to increase yields or grain quality.
    4. Soil Degradation: Imbalanced nutrient use reduces soil organic carbon and long-term productivity.

    Why Nutrient Use Efficiency Remains Low

    1. Low NUE Levels: Estimated at only 35-40%, indicating large nutrient losses.
    2. Atmospheric Losses: Nitrogen escapes as nitrous oxide, a greenhouse gas ~278 times more potent than CO₂.
    3. Water Pollution: Nitrate leaching contaminates groundwater, making it non-potable.
    4. Diversion and Leakage: ~20-25% of subsidised urea diverted to non-agricultural uses or smuggled across borders.
    5. Declining Response Ratio: Fertiliser-to-grain response ratio fell from ~1:10 (1970s) to ~1:2.7 (2015).

    What Policy Design Lessons Emerge from China

    1. Per-Unit Land Subsidy: Direct input subsidy on a per-mu basis rather than product-based price control.
    2. Market-Determined Prices: Fertiliser prices allowed to reflect market conditions.
    3. Innovation Incentives: Over 60% fertiliser consumption through complex fertilisers.
    4. Integrated Nutrient Management: Policy steers farmers toward balanced nutrient application.
    5. Outcome: Higher productivity with better nutrient balance despite higher fertilizer intensity.

    What Reform Pathways Does the Article Propose

    1. Gradual Price Decontrol: Phased dismantling of urea price controls.
    2. Direct Income Support: Protects farmers through equivalent cash transfers.
    3. NBS Recalibration: Reduce nitrogen subsidy while increasing support for phosphorus and potassium.
    4. Micronutrient Promotion: Encourages customised blends and soluble fertilisers through fertigation.
    5. Data Integration: Identification of tenant farmers using PM-KISAN data, land records, satellite imagery, and fertiliser sales.

    What Are the Expected Gains from Reform

    1. Fiscal Savings: Estimated annual savings of ~â‚č40,000 crore.
    2. Resource Reallocation: Redirects funds toward agri-R&D, irrigation, and high-value agriculture.
    3. Income Enhancement: Precision farming and balanced nutrients improve yield quality and farm profitability.
    4. Environmental Protection: Reduces greenhouse emissions and groundwater contamination.
    5. Growth Multiplier: Higher rural incomes stimulate demand for manufactured goods.

    Conclusion

    Reforming the fertiliser subsidy regime is not a question of fiscal retrenchment but of policy correction. By restoring price signals, improving nutrient balance, and protecting farmers through direct support, India can convert a distortionary subsidy into a productivity-enhancing instrument. The challenge is political, but the rewards are structural and long-term.
