  • How land pooling solves acquisition woes

    Why in the News?

    Rajasthan has announced its first-ever land pooling scheme, signalling a major shift in the way urban land is assembled for infrastructure and development projects.

    What is land pooling?

    Land pooling is a land acquisition strategy where landowners voluntarily hand over their land parcels to a government agency or development authority. The authority consolidates (pools) the land, builds modern infrastructure and then returns a smaller but highly developed portion of the land back to the original owners.

    How does land pooling work?

    1. Pooling: Landowners voluntarily transfer their fragmented, irregular plots to a central authority to create one continuous tract.
    2. Infrastructure Development: The authority reserves a percentage of the total land to build roads, utilities, parks, and public services.
    3. Reconstitution: The authority reorganises the remaining land into a planned layout of commercial, residential, and industrial plots.
    4. Return: Each landowner receives back a physically smaller but highly developed plot equipped with modern amenities and significantly higher market value.

    Example

    Gujarat Town Planning (TP) Model

    1. Land Contribution: Landowners typically contribute about 25-40% of their land.
    2. Land Return: Approximately 60-75% of land is returned as serviced plots.
    3. Integrated Development: Combines land assembly, infrastructure provision, cost recovery, and urban planning within a single framework.

    How is land pooling governed in India?

    Land pooling in India is governed through a decentralized framework managed primarily by individual state governments, rather than a single central federal law. The structural and legal governance framework breaks down into four primary tiers:

    1. Constitutional Authority: Under the Constitution of India, Land and Colonisation fall explicitly under the State List (List II, Seventh Schedule).
    2. State-Specific Legislative Acts
      1. The Mechanism: States enact standalone Town Planning Acts or Urban Development Acts that provide the legal backbone for land pooling.
      2. Examples: Notable examples include the Gujarat Town Planning and Urban Development Act, 1976, and the Andhra Pradesh Capital Region Development Authority Act, 2014, which laid out the legal rules for building the city of Amaravati.
    3. Execution by Development Authorities
      1. The Mechanism: State governments delegate the actual implementation and policing of land pooling schemes to specialized Urban Development Authorities.
      2. The Power: Entities like the Delhi Development Authority (DDA) or the Mumbai Metropolitan Region Development Authority (MMRDA) are legally authorized to notify zones for pooling, verify land titles, collect landowner consensus, and re-allot reconstituted plots.
    4. Judicial Oversight and Grievance Redressal
      1. The Mechanism: State pooling policies mandatorily incorporate dedicated dispute resolution tribunals, appellate authorities, or arbitrators.

    How Has Traditional Land Acquisition Become a Constraint to Urban Infrastructure Development?

    1. Procedural Complexity: Land acquisition has historically been lengthy, litigation-prone, and administratively challenging.
    2. Post-2013 Cost Escalation: The Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013 increased compensation, rehabilitation, and resettlement obligations.
    3. Financial Burden: Higher compensation requirements have significantly increased project costs.
    4. Implementation Gap: Planned infrastructure often remains under-executed due to inability to mobilise land.
    5. Urbanisation Pressure: Expanding cities require large-scale land assembly for roads, public facilities, housing, and economic infrastructure.

    Why Is Land Pooling Considered More Equitable Than Compulsory Acquisition?

    1. Participatory Planning: Landowners remain stakeholders rather than losing ownership entirely.
    2. Reduced Displacement: Limits physical displacement compared to conventional acquisition.
    3. Value Capture: Landowners benefit from appreciation in land value after infrastructure development.
    4. Financial Sustainability: Infrastructure costs are recovered through incremental development charges rather than large upfront expenditure.
    5. Social Acceptance: Voluntary participation reduces resistance and legal disputes.
    6. Environmental Protection: Facilitates planned development while preserving environmentally sensitive areas.

    Why Is Gujarat Considered India’s Most Successful Land Pooling Model?

    1. Historical Evolution: Land pooling was introduced nearly 100 years ago.
    2. Legal Foundation: Formalised under the Gujarat Town Planning and Urban Development Act, 1976.
    3. Large-Scale Implementation: More than 1,000 sq. km. has been planned through TP schemes.
    4. Geographical Coverage: Implemented across Ahmedabad, Surat, Rajkot, Vadodara, and Gandhinagar.
    5. Institutional Continuity: Strong legal backing and administrative experience enabled long-term success.
    6. Urban Expansion: Facilitated orderly peripheral growth and infrastructure provision.

    Why Has Maharashtra Recently Revived Interest in Land Pooling?

    1. Statutory Limitations: Existing legal provisions were not adequately updated for TP schemes.
    2. Recent Adoption: The model has gained momentum in Pune and the Mumbai Metropolitan Region Development Authority (MMRDA).
    3. Peripheral Development: Supports infrastructure creation and serviced land development in expanding urban regions.
    4. Growth Management: Provides an alternative to fragmented urban expansion.

    Why Land Pooling Initiatives like Guwahati Face Difficulties?

    1. Institutional Challenges
      1. Legal Gaps: The Guwahati Metropolitan Development Authority Act, 1985 lacked clarity on land appropriation percentages and institutional responsibilities.
      2. Implementation Ambiguity: Development scheme preparation procedures remained inadequately specified.
    2. Land Records Challenges
      1. Manual Records: Land records were not digitised.
      2. Record Mismatch: Discrepancies existed between revenue records and actual ground conditions.
    3. Administrative Solutions
      1. Existing Map Utilisation: Authorities retained existing maps instead of conducting extensive joint surveys.
      2. Revenue-Based Allocation: Final plot allocation was based on land area recorded in revenue documents.
      3. Time Efficiency: Reduced scheme preparation time.
    4. Contribution Adjustment
      1. Reduced Contribution: Private landowners contributed only 12-15% of land.
      2. Comparison: Conventional schemes generally require 35–45% land contribution.
      3. Infrastructure Focus: Contributed land was primarily used for road development.

    How Is Rajasthan Attempting to Make Land Pooling More Viable?

    1. Statutory Recognition: Land pooling provisions already existed since 2016.
    2. Implementation Push: Rajasthan is now operationalising the framework.
    3. Land Value Reforms: Modifications are being made to land-value calculations.
    4. Cost Sharing: Government has absorbed part of the development cost.
    5. Financial Equity: Reduces burden on participating landowners.
    6. Stakeholder Acceptance: Makes participation more attractive.

    What Factors Will Determine the Success of Future Land Pooling Schemes?

    1. Stakeholder Trust: Requires convincing landowners of long-term benefits.
    2. Legislative Clarity: Ensures certainty regarding rights, obligations, and compensation.
    3. Digital Land Records: Improves transparency and reduces disputes.
    4. Flexible Contribution Models: Allows adaptation to local realities.
    5. Institutional Capacity: Strengthens planning authorities and implementation agencies.
    6. Equitable Financial Models: Distributes costs and benefits fairly.
    7. Context-Specific Design: Avoids one-size-fits-all approaches.

    Conclusion

    Land pooling represents a shift from a compensation-centric model of land acquisition to a partnership-based model of urban development. The experiences of Gujarat, Maharashtra, Guwahati, and Rajasthan demonstrate that success depends less on the concept itself and more on institutional capacity, legal clarity, digitised land records, and equitable benefit-sharing. As India’s urbanisation accelerates, land pooling can become a critical instrument for balancing infrastructure needs with property rights and inclusive development.

  • Why do cities get polluted in summer

    Why in the News?

    Summer air pollution has emerged as a major concern after the Commission for Air Quality Management (CAQM) revoked all restrictions under the Graded Response Action Plan (GRAP) in March 2026. This marked the end of the winter pollution season in Delhi-NCR. However, persistent pollution episodes during April-May, including 54 days of PM10 exceedances in Delhi, forced authorities to reimpose GRAP Stage-I measures. This highlights that air pollution is no longer a winter-only problem and requires year-round management.

    How does summer air pollution differ from winter pollution?

    Winter pollution is dominated by PM2.5 accumulation

    1. Temperature Inversion: Traps pollutants near the surface.
    2. Low Wind Speeds: Restrict pollutant dispersion.
    3. Basin-like Topography: Especially in Delhi and the Indo-Gangetic Plain, facilitates pollutant accumulation.
    4. Biomass Burning: Adds substantial PM2.5 load during winter months.

    Summer pollution is dominated by PM10 and ozone

    1. Coarse Particulate Matter (PM10): Generated from dust storms, road dust, construction activity, and resuspended dust.
    2. Ground-Level Ozone: Formed through photochemical reactions under strong sunlight and high temperatures.
    3. Stronger Winds: Enhance pollutant dispersion but simultaneously transport dust across regions.
    4. Thunderstorms: Can temporarily improve air quality through atmospheric cleansing.

    Why are Indian cities witnessing pollution episodes during summer

    Meteorological conditions differ from winter but remain conducive to pollution

    1. Higher Temperatures: Accelerate atmospheric chemical reactions.
    2. Intense Solar Radiation: Enhances ozone formation.
    3. Dust Transport: Winds carry dust over long distances.
    4. Regional Variability: Different cities experience different dominant pollutants.

    Evidence from major cities

    1. Delhi: Recorded 54 days exceeding PM10 standards during April–May 2026.
    2. Mumbai: Experienced elevated PM10 and ozone levels due to construction activity, dust, and traffic.
    3. Hyderabad: Reported pollution spikes despite relatively better ventilation conditions.
    4. Kolkata and Chennai: Recorded ozone and PM10 exceedances on multiple days.
    5. Bengaluru: Witnessed increasing summer ozone episodes.

    What causes PM10 spikes during summer months?

    Dust storms emerge as the primary driver

    1. West Asian Dust Transport: Dust originating from subcontinent-adjacent arid regions interacts with local weather systems.
    2. Dust Intrusion: Dust can travel from arid landscapes toward northern India during strong wind events.
    3. Atmospheric Instability: Supports long-range transport of coarse particles.

    Local dust generation worsens pollution

    1. Construction Activities: Release large quantities of coarse dust particles.
    2. Demolition Work: Contributes significantly to suspended particulate matter.
    3. Road Dust Resuspension: Moving vehicles continuously lift deposited dust.
    4. Urban Expansion: Increases exposed surfaces vulnerable to wind erosion.

    Data from Delhi

    1. PM10 Exceedance Days (April-May 2026): 54 days exceeded 24-hour NAAQS limits.
    2. Hourly Exceedances: At least one CAAQMS crossed 180 μg/m³ on 40 days.

    Why does ozone pollution increase during hot weather?

    1. Ozone is a secondary pollutant
      1. No Direct Emission: Ground-level ozone is not emitted directly.
      2. Photochemical Formation: Forms through reactions involving precursor pollutants. Major precursors
        1. Nitrogen Oxides (NOx): Emitted from vehicles and industries.
        2. Volatile Organic Compounds (VOCs): Released from fuels, solvents, paints, industrial processes, and vehicle exhaust.
    2. Meteorological triggers
      1. High Temperature: Accelerates reaction rates.
      2. Strong Sunlight: Provides energy required for ozone formation.
      3. Heatwaves: Create highly favorable conditions for ozone accumulation.
    3. Public health implications
      1. Respiratory Disorders: Causes breathing difficulties.
      2. Lung Irritation: Damages respiratory tissues.
      3. Public Health Risk: Particularly affects children, elderly persons, and individuals with pre-existing respiratory illnesses.

    How do dust storms affect air quality in India?

    Dust storms have regional impacts

    1. PM10 Surges: Produce sudden spikes in particulate pollution.
    2. Cross-Border Influence: Dust can travel across large geographical areas.
    3. Reduced Visibility: Impairs transportation and public safety.

    Indian context

    1. Northern India: Frequently affected due to proximity to desert regions.
    2. Thunderstorm-Associated Dust Events: Strong downdrafts lift and transport loose soil particles.
    3. Pre-Monsoon Season: Experiences maximum dust storm frequency.

    How do human activities worsen summer air pollution?

    1. Construction Activities: Generate large quantities of coarse particulate matter (PM10) through excavation, demolition, and material handling. Construction dust remains a major contributor to urban summer pollution.
    2. Road Dust Resuspension: Heavy vehicular movement lifts deposited dust from roads, significantly increasing PM10 concentrations during dry summer conditions.
    3. Vehicular Emissions: Release particulate matter, nitrogen oxides (NOx), and volatile organic compounds (VOCs). These contribute directly to particulate pollution and indirectly to ozone formation.
    4. Industrial Emissions: Emit NOx, VOCs, and other pollutants that participate in photochemical reactions responsible for ground-level ozone formation.
    5. Poor Dust Management: Inadequate covering of construction materials, unpaved surfaces, and weak enforcement of dust-control norms aggravate particulate pollution.

    What forecasting mechanisms are available for managing summer pollution?

    1. Air Quality Early Warning System (AQEWS)
      1. Origin: Developed following severe dust storm and smog events.
      2. Coverage Expansion: Extended from Delhi to cities such as Jaipur and Mumbai.
      3. Forecast Capability: Provides multi-day pollutant forecasts.
      4. Integrated Weather Information: Supports proactive response measures.
    2. IMD Air Quality Bulletins
      1. Forecast Frequency: Released several times daily.
      2. Coverage: Delhi and approximately 140 Indian cities.
      3. Utility: Facilitates issuance of public advisories and exposure reduction measures.

    What measures can cities adopt to combat summer air pollution?

    1. Forecast-based interventions
      1. Early Warning Systems: Enable advance preparedness. Authorities can use IMD’s weather forecast bulletins to issue local alerts for dust storms, poor air quality and ozone to the citizens.
      2. Public Health Advisories: Reduce citizen exposure during high-pollution episodes.
    2. Dust management measures
      1. Construction Site Monitoring: Ensures compliance with dust-control norms.
      2. Mechanical Road Sweeping: Reduces loose particulate matter.
      3. Dust Suppression Technologies: Minimize resuspension.
      4. Study by Council on Energy, Environment and Water found that simply reducing heavy-vehicle movement at construction sites can lower local PM levels.
      5. Example: The Brihanmumbai Municipal Corporation’s Air Quality Decision Support System (AQDSS) monitors construction sites and has helped authorities take action against more than 1,000 construction sites since October 2025, demonstrating the importance of strict dust-control compliance.
    3. Vehicular emission reduction
      1. Cleaner Transport Systems: Reduce NOx emissions.
      2. Traffic Management: Limits idling emissions.
      3. Public Campaigns: Encourage behavioral change.
      4. Example: Delhi’s “Red Light On, Gaadi Off” Campaign: Encourages drivers to switch off engines at traffic signals to reduce emissions.

    Key Dust-Control Norms in India

    1. Covering of Construction Materials: Sand, soil, cement, and debris must be covered to prevent wind-blown dust.
    2. Anti-Smog Guns and Water Sprinkling: Mandatory at large construction sites to suppress airborne dust.
    3. Green Nets/Wind Barriers: Installed around sites to prevent dust dispersion into surrounding areas.
    4. Covered Transportation: Trucks carrying C&D waste or raw materials must be covered with tarpaulin sheets.
    5. Wheel-Washing Facilities: Vehicles exiting construction sites should pass through wheel-washing systems to prevent mud and dust deposition on roads.
    6. Mechanical Road Sweeping: Regular cleaning of adjoining roads to remove accumulated dust.
    7. Paved Internal Roads: Reduces dust generation from vehicle movement within sites.
    8. Proper C&D Waste Management: Segregation, storage, recycling, and scientific disposal of construction waste.

    CAQM’s Framework for Dust Mitigation in NCR

    1. Mandatory dust management plans for large projects.
    2. Real-time monitoring of construction activities.
    3. Penalties and project shutdowns for repeated violations.
    4. Use of remote sensing and inspection teams for enforcement. 

    Why is a year-round strategy necessary?

    1. Continuous Forecasting: Enables advance warnings for dust storms, ozone episodes, and deteriorating air quality through systems such as AQEWS and IMD forecasts.
    2. Season-Specific Interventions: Requires winter measures for PM2.5 control, summer dust-management measures for PM10 reduction, and targeted NOx-VOC controls for ozone mitigation.
    3. Public Health Protection: Reduces exposure through timely advisories during heatwaves, dust storms, and ozone episodes.
    4. Institutional Preparedness: Ensures mechanisms such as GRAP, municipal action plans, and pollution monitoring systems remain operational throughout the year rather than only during winter.
    5. Integrated Urban Air Quality Governance: Combines forecasting, construction dust regulation, road dust management, cleaner transport, and industrial emission controls into a continuous management framework.

    Conclusion

    The rise of summer pollution episodes demonstrates that India’s air quality challenge extends far beyond winter smog. Dust storms, PM10 pollution, and ground-level ozone have transformed summer into a critical pollution season. Effective air quality governance now requires year-round monitoring, forecasting, dust control, emission reduction, and public health preparedness across all major urban centres.

      1. James Joyce: “To live, to err, to fall, to triumph, to recreate life out of life.”
      2. Richard Feynman: “What I cannot create, I do not understand.”
      3. J. Robert Oppenheimer: “See things not as they are, but as they might be.”
    5. Future Potential: Genome synthesis may eventually allow creation of larger synthetic genomes and engineered organisms.

    How Does Bottom-Up Synthetic Biology Attempt to Recreate the Origin of Life?

    1. Bottom-Up Synthetic Biology: Seeks to construct living systems from scratch using non-living chemical components. Instead of modifying existing organisms, it attempts to recreate the earliest stages through which life may have emerged on Earth.
    2. Scientific Objective: Examines one of biology’s fundamental questions, how non-living molecules transformed into self-replicating living systems approximately 4 billion years ago.
    3. Protocell Construction: Researchers build simplified cell-like structures called protocells, which mimic some characteristics of primitive life forms but are not fully living organisms.
    4. Jack Szostak’s Research: Developed fatty-acid membrane structures that can spontaneously assemble, encapsulate RNA molecules, grow by incorporating surrounding molecules, and divide into smaller daughter structures.
    5. Origin of Life Studies: Such experiments help scientists understand how the first biological cells may have formed before the evolution of complex organisms.
    6. Future Possibilities: Success in creating self-replicating protocells could eventually enable the development of entirely new forms of artificial life designed for specific purposes.
    7. Example: Jack Szostak’s protocell experiments demonstrated that simple fatty-acid vesicles can spontaneously form membrane-bound compartments capable of enclosing RNA and undergoing growth and division, providing a possible model for the earliest stages of life on Earth.

    Why Does Synthetic Biology Create Unique Governance Challenges?

    1. Self-Replicating Systems: Unlike machines, living organisms can reproduce and evolve.

  • Remittance anchor the rupee, India’s external balances

    Why in the News?

    The Indian rupee has lost nearly 12% of its value against the U.S. dollar since May 2025, leading to renewed concerns regarding India’s external-sector vulnerability. Many analysts have attributed this trend to weakening foreign investment inflows. But at the same time, India received $138 billion in remittances in 2024, making it the world’s largest remittance recipient by a wide margin. More significantly, remittances have, on average, financed more than the entirety of India’s trade deficit since mid-2013.

    What are Remittances?

    1. A remittance refers to the transfer of money from one party to another, most commonly signifying foreign remittance, which involves cross-border funds transferred between individuals or entities in India and abroad. 
    2. While it technically encompasses domestic wire transfers, the term is primarily used for the money sent home by Non-Resident Indians (NRIs) and migrant workers to support their families or make investments.

    Types of Remittances in India

    The Reserve Bank of India (RBI) and the Foreign Exchange Management Act (FEMA) classify these financial transfers into two main types: 

    1. Inward Remittance: Funds sent from a foreign country into a domestic bank account in India. An example is an NRI working in the United States sending money to their parents living in Mumbai.
    2. Outward Remittance: Funds sent from a local bank account in India to an account located abroad. An example is parents in India sending money to a child studying at a university in Singapore.

    Why Does the Conventional Explanation for Rupee Depreciation Present an Incomplete Picture?

    1. Rupee Depreciation: The rupee has depreciated by nearly 12% against the U.S. dollar since May 2025.
    2. FDI Narrative: Several analysts attribute the depreciation primarily to declining net FDI inflows.
    3. FPI Narrative: Volatile portfolio investments are also cited as a major source of pressure on the rupee.
    4. Negative Net FDI: Net FDI became negative in Q2 FY2025-26 after showing a declining trend since Q2 FY2021-22.
    5. Analytical Gap: Excessive attention to Financial Account flows understates the contribution of remittances recorded under the Current Account.

    If Net FDI Has Turned Negative, Why Has India’s External Position Not Deteriorated More Sharply?

    1. Remittance Cushion: Large remittance inflows continue to provide foreign exchange despite weakening capital flows.
    2. Scale of Inflows: India received approximately $138 billion in remittances during 2024.
    3. CAD Financing: Remittances absorb a substantial portion of the financing burden created by trade deficits.
    4. Exchange-Rate Support: Stable inflows reduce pressure on the rupee and foreign exchange reserves.
    5. External Stability: Remittances offset some of the risks arising from negative FDI and volatile FPI.

    What is the Current Account Deficit (CAD)? (Points Form)

    1. Definition: Current Account Deficit arises when a country’s payments to the rest of the world exceed its receipts through the Current Account of the Balance of Payments.
    2. Components of Current Account:
      1. Trade Balance (Exports-Imports of Goods)
      2. Net Services (IT, tourism, shipping, etc.)
      3. Net Primary Income (interest, dividends, profits)
      4. Net Secondary Income (remittances, gifts, grants)
    3. Cause: Occurs when imports and income outflows exceed exports, services earnings and transfer receipts.
    4. Significance: Indicates the extent to which a country depends on external financing.
    5. Financing Sources: FDI, FPI, external commercial borrowings and foreign exchange reserves.
    6. Impact of High CAD:
      1. Increases external vulnerability.
      2. Creates depreciation pressure on the domestic currency.
      3. Raises dependence on foreign capital inflows.
    7. India-Specific Context: Large remittance inflows generate a surplus under Net Secondary Income (NSI), which helps reduce the CAD and strengthens external-sector stability.

    How Have Remittances Financed More Than the Entire Trade Deficit Since Mid-2013?

    This is due to their immense scale, steady growth, and structural shift toward high-value transfers from advanced economies. In India’s Balance of Payments (BoP), the massive gap created by importing more goods than exporting (the merchandise trade deficit) is largely cancelled out by “invisibles,” where remittances play an anchoring role.

    1. Record Inflows: India received approximately $138 billion in remittances in 2024, making it the world’s largest remittance recipient and generating foreign exchange inflows equivalent to nearly 3% of GDP.
    2. Net Secondary Income Surplus: Remittances constitute the largest component of India’s Net Secondary Income (NSI) surplus in the Current Account.
    3. Trade Deficit Offset: The NSI surplus generated by remittances offsets a substantial portion of the merchandise trade deficit.
    4. Structural Shift in Sources: A growing share of remittances originates from high-income economies, increasing the value and stability of transfers.
    5. Sustained Foreign Exchange Buffer: Consistently positive remittance inflows have enabled them to finance more than the entirety of India’s trade deficit on average since mid-2013.

    What Has Been the Impact of Remittances on India’s External Sector?

    1. Current Account Impact: Net Secondary Income surpluses significantly reduce the Current Account Deficit.
    2. Residual CAD: Remaining deficits become substantially smaller after accounting for remittance inflows.
    3. Financing Burden: Lower CAD reduces the amount that must be financed through FDI, FPI or external borrowing.
    4. External Resilience: Remittances act as the first line of defence against external imbalances and sudden capital-flow reversals.
    5. Exchange Rate Support: Stable foreign exchange inflows reduce pressure on the rupee and forex reserves.

    How Do Remittances Reduce India’s Dependence on FDI and FPI?

    1. Trade Deficit Absorption: Remittance inflows offset a substantial portion of India’s merchandise trade deficit.
    2. CAD Reduction: Net Secondary Income (NSI) surpluses narrow the Current Account Deficit.
    3. Lower External Financing Needs: A smaller CAD requires less financing through FDI, FPI and external borrowing.
    4. Reduced Vulnerability: Lower dependence on volatile capital flows strengthens external-sector stability.
    5. Exchange Rate Support: Stable foreign exchange inflows help moderate pressure on the rupee.

    Are Remittances a More Reliable Source of External Financing Than FDI and FPI?

    1. Scale: Remittances amount to nearly 3% of GDP and exceed net FDI and FPI inflows.
    2. Stability: Household-driven transfers exhibit lower volatility than financial investments.
    3. Continuity: Family obligations sustain flows even during periods of uncertainty.
    4. Predictability: Migrant earnings and savings decisions generate more stable inflows.
    5. Resilience: Remittances rarely experience sudden stops comparable to capital flight.

    Why Do Remittances Strengthen India’s External Position Without Creating Future Liabilities?

    1. Transfer Nature: Remittances are transfers rather than investment claims.
    2. Liability-Free Inflows: Remittances do not require repayment.
    3. No Profit Repatriation: Unlike FDI, remittances do not generate future dividend or profit outflows.
    4. No Exit Risk: Unlike FPI, remittances cannot be withdrawn from domestic financial markets.
    5. Low Vulnerability: Remittances strengthen the external sector without creating future obligations.

    Conclusion

    India’s external resilience is increasingly anchored in remittances rather than volatile capital flows. While FDI and FPI remain important, remittances have financed a substantial share of the trade deficit, reduced the Current Account Deficit and supported the rupee without creating future liabilities. A comprehensive assessment of India’s external-sector health must therefore place remittances alongside, and in some contexts above, conventional measures of foreign capital inflows.

  • EU Carbon Border Adjustment Mechanism (CBAM)

    Why in the news?

    A recent study by the Potsdam Institute for Climate Impact Research stated that the European Union’s Carbon Border Adjustment Mechanism (CBAM) could significantly strengthen global climate action and reduce carbon leakage.

    What is CBAM?

    The Carbon Border Adjustment Mechanism (CBAM) is:

    • A carbon tariff imposed by the European Union on imports of carbon intensive products.
    • Importers must pay a carbon levy unless the exporting country already has an equivalent carbon pricing system.

    Objectives of CBAM

    • Prevent: Carbon leakage
    • Protect: EU industries from unfair competition
    • Encourage: Other countries to adopt carbon pricing policies
    • Support: Global decarbonisation efforts

    What is Carbon Leakage?

    Carbon leakage occurs when:

    • Industries shift production from countries with strict climate policies to countries with weaker environmental regulations.
    • This causes emissions reductions in one country to be offset by increased emissions elsewhere.

    Findings of the Study

    • Without CBAM, Around 40% of EU emission reductions could be offset by carbon leakage.
    • With CBAM, Carbon leakage could be reduced to 15%.
    • Global emission reductions may increase significantly if major trading partners adopt carbon pricing systems.

    What is Carbon Pricing?

    Carbon pricing means:

    • Putting a monetary cost on carbon emissions to reduce greenhouse gas emissions.
    • Major forms: Carbon tax and Emissions Trading System (ETS)

    Criticism of CBAM

    Critics argue:

    • Developing countries may face higher export costs.
    • It may act as a trade barrier.
    • EU does not provide sufficient:
      • Climate finance
      • Technology support
        for industrial decarbonisation in poorer countries.

    [2023] Consider the following statements:
    Statement-I:Carbon markets are likely to be one of the most widespread tools in the fight against climate change.
