[1st September 2025] The Hindu Op-ed: India’s economic churn, the nectar of growth

op-ed snap | Economics | Mains Paper 3: Indian Economy

PYQ Relevance

[UPSC 2019] Do you agree with the view that steady GDP growth and low inflation have left the Indian economy in good shape? Give reasons in support of your arguments.

Linkage: India’s steady GDP growth of 7.8%, coupled with broad-based sectoral performance, reflects macroeconomic stability, while effective fiscal and monetary discipline underpins low inflation. The sovereign rating upgrade after 18 years validates external confidence in India’s fundamentals. These trends, along with inclusive poverty reduction, highlight that the economy is indeed in good shape.

Mentor’s Comment

India’s economy is once again at the centre of global attention. From being dismissed as a “dead economy” by sceptics, the latest economic data, sovereign rating upgrade, and energy security achievements have painted a powerful picture of resilience and renewal. This article unpacks the recent developments in India’s economic and energy story, their significance, and what they mean for aspirants of Viksit Bharat.

Why is this issue in the news?

India’s Q1 FY 2025-26 GDP figures revealed 7.8% real growth, the fastest among major economies, coupled with a historic sovereign rating upgrade by S&P Global after 18 years. Simultaneously, India has consolidated its position as the world’s third-largest energy consumer and is spearheading a green transition. These milestones are striking because they overturn the “dead economy” narrative, highlight India’s growing share in global growth, and showcase a balance between growth, reform, and welfare, all while maintaining democratic values in contrast to authoritarian models of fast-paced growth.

Introduction

Indian civilisation has always embraced the philosophy that turbulence precedes triumph, like the Samudra Manthan, where chaos yielded nectar. Similarly, India’s economic journey has turned crises into opportunities, from the liberalisation of 1991 to the digital surge during COVID-19. Today, India stands at another inflection point. Despite global headwinds and doubts, the country is demonstrating robust growth, deepening reforms, and a secure energy base, shaping the narrative of resilience and inclusive progress.

Broad-based economic growth

  1. GDP expansion: Real GDP grew 7.8% in Q1 FY 2025-26, while GVA rose 7.6%, supported by manufacturing (7.7%), construction (7.6%), and services (9.3%).
  2. Global standing: India is the world’s fourth-largest economy and the fastest-growing major one, projected to overtake Germany by decade’s end.
  3. Global contribution: Independent estimates suggest India contributes 15% of incremental world growth, with ambitions to raise it to 20%.

Why the sovereign rating upgrade matters

  1. S&P recognition: First upgrade in 18 years, citing robust growth, fiscal consolidation, and monetary credibility.
  2. Lower borrowing costs: Improves India’s access to cheaper capital and widens the investor base.
  3. Narrative shift: Counters the label of a “dead economy,” giving credibility to India’s reforms.

Growth with inclusion

  1. Poverty reduction: 24.82 crore Indians moved out of multidimensional poverty between 2013-14 and 2022-23.
  2. Last-mile delivery: Success through bank accounts, clean cooking fuel, health cover, tap water, and direct benefit transfers (DBT).
  3. Democratic model: Built on consensus, competitive federalism, and digital rails, contrasting authoritarian growth models.

Energy security as a growth driver

  1. Global role: India is the third-largest energy consumer, fourth-largest refiner, and fourth-largest LNG importer.
  2. Capacity expansion: Refining capacity of 5.2 mb/d with plans to cross 400 MTPA by 2030.
  3. Exploration reforms: Sedimentary basin coverage expanded to 16% in 2025 (from 8% in 2021), with 1 million sq km target by 2030.
  4. Gas reforms: New pricing linked to Indian crude basket; 20% premium for deepwater wells boosting investment.

India’s energy transition

  1. Ethanol blending: Surged from 1.5% (2014) to 20% today, saving ₹1.25 lakh crore forex and paying ₹1 lakh crore to farmers.
  2. Green fuels: 300 compressed biogas plants under SATAT, targeting 5% blending by 2028.
  3. Hydrogen push: Oil PSUs driving the green hydrogen mission.

Responding to global criticism on Russian oil

  1. Compliance: India operates fully within G-7/EU price cap systems; every transaction uses legal, audited channels.
  2. Global stabiliser: Purchases prevented oil shocks and stabilised prices, aligning with Vasudhaiva Kutumbakam.
  3. Export reality: India has been a top petroleum exporter for decades, not a “laundromat” for Russia.

India’s digital-industrial revolution

  1. Semiconductors: Four new projects cleared under the India Semiconductor Mission; strengthened by Japan collaborations.
  2. Digital economy: India leads in real-time payments; UPI enhances small-business productivity and exports of solutions.
  3. Synergy: Gati Shakti logistics & digital rails reduce costs, formalise the economy, and spur consumption.

Conclusion

India’s recent performance is more than statistics, it is the reaffirmation of resilience, reform, and inclusion. The world’s doubters labelled it a “dead economy,” yet growth, energy security, digital leadership, and poverty reduction tell a different story. As reforms deepen, India is on track not just to become the world’s third-largest economy soon but also to build a model of democratic, inclusive, and sustainable growth. For India, Viksit Bharat is not aspiration, it is delivery in motion.

J&K – The issues around the state

The importance of India’s federal design

Explained | Polity | Mains Paper 2: Federalism

Introduction

India’s federal design is unique, balancing a strong Union with an inclusive representation of States. The abrogation of Article 370 and the downgrading of Jammu and Kashmir into a Union Territory in 2019 raised critical constitutional and political debates. The Supreme Court’s December 2023 ruling upheld the abrogation but directed restoration of statehood. While elections were held in October 2024, the absence of progress on restoring statehood highlights a sharp tension between constitutional intent and political practice. The issue has become a litmus test of Indian federalism, bringing into focus the balance between unity, diversity, and democratic representation.

The Demand for Restoration of Statehood to Jammu and Kashmir

  1. Supreme Court Intervention: Recently, the Court sought a detailed response from the Centre on the timeline for restoring statehood to J&K.
  2. Sharp Contrast: While elections were held in 2024, statehood has not been restored, despite the Court’s explicit direction.
  3. Federal Implications: Critics argue that prolonged delay undermines federalism, part of the Constitution’s basic structure, and weakens democratic rights of J&K’s citizens.
  4. Striking Point: For the first time, a full-fledged State was downgraded into a Union Territory, setting a precedent that challenges constitutional norms.

Constitutional Processes for the Creation of States

  1. Admission: Admission of new States requires an organised political unit; e.g., J&K’s Instrument of Accession (1947).
  2. Establishment: Territory can be acquired under international law, as in the case of Goa and Sikkim.
  3. Formation: Article 3 empowers Parliament to reorganise existing States by altering boundaries, names, or creating new ones.

India’s Federal Design and Its Unique Character

  1. Union of States: Article 1 describes India as a Union of States, signifying indivisibility while denying the right of secession.
  2. Composite Culture: The dual identity of India and Bharat reflects political unity and cultural plurality.
  3. Unitary Tilt: The word Union ensures a strong Centre, but representation of States through the Rajya Sabha balances federalism.
  4. Basic Structure Doctrine: Federalism is recognised as part of the Basic Structure, making it inviolable.

Constitutional Imperatives for Restoring Statehood

  1. Violation of Federal Features: The Union can reorganise States but cannot permanently strip a State into a Union Territory.
  2. Supreme Court’s Directive: In December 2023, the Court mandated restoration of statehood along with Assembly elections.
  3. Representation at the Centre: Permanent representation of States in the Rajya Sabha is essential to sustain India’s federalism.
  4. Erosion of Trust: Prolonged delay risks alienating citizens and eroding India’s image as a welfare-oriented union.

The Road Ahead for Jammu and Kashmir

  1. Elections Held: A 90-member Assembly election was conducted in October 2024.
  2. Centre’s Silence: No concrete roadmap has been shared for restoring statehood, despite judicial directions.
  3. Critics’ Argument: Restoring statehood would empower the elected government, reducing the powers of the Lieutenant Governor, which the Union may be reluctant to cede.
  4. Constitutional Morality: Failure to restore statehood risks weakening the principle of cooperative federalism.

Conclusion

The demand for restoration of J&K’s statehood is not a mere political debate but a constitutional necessity. India’s federal design hinges upon the delicate balance between a strong Union and empowered States. If the Union delays restoration indefinitely, it risks setting a precedent that erodes the sanctity of federalism and weakens democratic representation. Upholding statehood is thus not only about J&K but about preserving the essence of India’s constitutional federation.

PYQ Relevance

[UPSC 2014] Though the federal principle is dominant in our Constitution and that principle is one of its basic features, but it is equally true that federalism under the Indian Constitution leans in favour of a strong Centre, a feature that militates against the concept of strong federalism. Discuss.

Linkage: The recent controversy over the restoration of statehood to Jammu & Kashmir directly exemplifies the asymmetry in India’s federal design. While federalism is a part of the Basic Structure, the downgrading of a full-fledged State into a Union Territory shows the unitary tilt of the Constitution. The Supreme Court’s directive to restore statehood reflects the tension between a strong Centre ensuring unity and the need to preserve the spirit of cooperative federalism, echoing the very debate raised in the 2014 question.

Climate Change Impact on India and World – International Reports, Key Observations, etc.

Data shows seas rising faster around Maldives, Lakshadweep than believed

Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Introduction

Sea-level rise is one of the most significant consequences of global warming, threatening ecosystems, economies, and human settlements. In the Indian Ocean, recent findings based on coral microatolls suggest that sea levels began rising rapidly as early as the 1950s, decades before satellite and tide-gauge data had indicated. This challenges existing assumptions in climate change studies and raises critical questions about preparedness for vulnerable island states like Maldives, Lakshadweep, and the Chagos archipelago.

Coral Microatolls as Natural Recorders of Sea-Level History

  • Unique natural recorders: Coral microatolls are disk-shaped colonies that stop growing upwards once constrained by the lowest tide, making their surface a natural reflection of long-term sea-level change.
  • Longevity and accuracy: They can survive for decades or centuries, providing high-resolution, continuous data.
  • Study site: Research conducted on Mahutigalaa reef, Huvadhoo Atoll (Maldives), measured a Porites microatoll covering 1930–2019.

Acceleration and Scale of Sea-Level Rise in the Indian Ocean

  • Accelerated rise: Data showed a 0.3 metre increase over 90 years.
  • Rates of rise:
    • 1930–1959: 1–1.84 mm/year
    • 1960–1992: 2.76–4.12 mm/year
    • 1990–2019: 3.91–4.87 mm/year
  • Striking revelation: Sea-level rise began in the late 1950s, not around 1990 as earlier assumed.
  • Cumulative impact: Maldives, Lakshadweep, and Chagos have witnessed 30–40 cm rise in half a century, worsening flooding and erosion risks.

Climate Variability and Environmental Signals Captured in Corals

  • Climate variability: Slow or interrupted coral growth coincided with El Niño and negative Indian Ocean Dipole (IOD) events.
  • Astronomical influence: The 18.6-year lunar nodal cycle was reflected in the growth bands, showing tidal and sea-level oscillations.
  • Tectonic stability: Critical factor ensuring that coral growth data reflects sea-level change rather than land movement.

Regional Significance of Findings for the Indian Ocean Basin

  • Above-average warming: The Indian Ocean is heating faster than the global average, amplifying sea-level fluctuations.
  • Strategic gaps: Despite its ecological and geopolitical importance, the central Indian Ocean is one of the least-monitored basins.
  • Regional variations: Coastal areas saw recent acceleration, but the central basin experienced earlier, stronger rise, influenced by shifts in Southern Hemisphere westerlies, ocean heat uptake, and the Intertropical Convergence Zone.

Vulnerabilities and Adaptation Imperatives for Island Nations

  • Existential threat: Infrastructure and communities are concentrated just above sea level in Maldives and Lakshadweep.
  • Adaptation strategies: Understanding historic timing and magnitude of sea-level rise is vital for coastal planning, disaster preparedness, and climate resilience.
  • Scientific value: Microatolls cannot replace tide gauges or satellites but offer a vital complementary tool to refine projections in data-sparse regions.

Conclusion

The discovery that sea-level rise in the Maldives and Lakshadweep began decades earlier than thought is a wake-up call for policymakers and communities. Coral microatolls, silent sentinels of the ocean, have revealed the urgency of accelerating adaptation and resilience measures. As the Indian Ocean warms faster than global averages, the survival of low-lying nations will depend on proactive international cooperation and evidence-based planning.

 

Value Addition

Global Reports and Scientific Frameworks

  • IPCC AR6 (2021–22): Predicts global mean sea level rise of 0.28–1.01 m by 2100, depending on emission scenarios.
  • World Meteorological Organization (WMO): State of the Global Climate 2023: Confirms Indian Ocean warming faster than the global average, intensifying regional sea-level anomalies.
  • UNFCCC & Paris Agreement: Commitments to limit warming below 2°C directly shape adaptation strategies for vulnerable island nations.

Case Studies for Enrichment

  • Maldives: Declared intent to become a carbon-neutral nation by 2030; adaptation measures include artificial islands and elevated infrastructure.
  • Kiribati (Pacific Island): Purchased land in Fiji to relocate populations – showcases climate migration.
  • Lakshadweep Islands: Reports of shoreline erosion, freshwater lens salinity, and threat to tourism livelihoods.

Scientific Concepts for Enrichment

  • Thermal Expansion: Ocean water expands as it warms, contributing ~50% to global sea-level rise.
  • Cryosphere–Ocean Linkages: Melting of Greenland & Antarctic ice sheets accelerates rise beyond thermal expansion.
  • Lunar Nodal Cycle (18.6 years): Natural oscillation in tides influencing local sea-level variability, as confirmed in microatoll data.

PYQ Relevance

[UPSC 2023] The Intergovernmental Panel on Climate Change (IPCC) has predicted a global sea level rise of about one metre by AD 2100. What would be its impact in India and the other countries in the Indian Ocean region?

Linkage: The article’s findings on coral microatolls show that sea-level rise in the Maldives, Lakshadweep, and Chagos began as early as the 1950s, much earlier than assumed. This reinforces IPCC projections of accelerated rise, highlighting existential risks for low-lying islands. For India and the wider Indian Ocean region, the impacts include intensified coastal erosion, loss of habitats, and the need for urgent adaptation strategies.

Climate Change Impact on India and World – International Reports, Key Observations, etc.

Collapse of Atlantic Meridional Overturning Circulation (AMOC)

Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

A new study warned that the collapse of the Atlantic Meridional Overturning Circulation (AMOC) is no longer a low-likelihood scenario.

What is AMOC?

  • Overview: It is a large system of ocean currents, part of the thermohaline circulation (THC) or global ocean conveyor belt.
  • Function: Moves warm tropical surface waters northward.
  • Deep Currents: In the North Atlantic, cooled water sinks and flows back south as deep currents.
  • Global Link: Connected to the Antarctic Circumpolar Current, making it part of a worldwide circulation system.
  • Key Role: Distributes heat and nutrients across the world’s oceans.

Collapse of Atlantic Meridional Overturning Circulation (AMOC)

Why is AMOC slowing down?

  • Melting Ice Sheets: Greenland and Arctic ice melt releases freshwater, lowering seawater density, preventing sinking, and weakening circulation.
  • Indian Ocean Warming (2019 Study): Extra rainfall in the Indian Ocean reduces rainfall in the Atlantic.
  • Temporary Boost: Atlantic water becomes saltier, sinks faster, giving AMOC short-term strengthening.
  • Future Outlook: Effect fades once Pacific and other oceans catch up in warming.
  • Climate Models: Predict a 34–45% weakening of AMOC by 2100 under continued global warming.

What happens if AMOC collapses?

  • Severe Cooling: Europe and the North Atlantic would face strong cooling.
  • Rainfall Reduction: Decline in rainfall over Europe.
  • ENSO Impact: Altered El Niño–Southern Oscillation patterns.
  • Sea Ice Expansion: Increase in Greenland–Iceland–Norwegian seas.
  • Rain-belt Shift: Southward movement over the tropical Atlantic.
  • Long-term Impact: Global climate instability with regional extremes.

Why are Killer Whales offering fresh prey to humans?

Prelims OnlySpecies | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the News?

A new study in the Journal of Comparative Psychology documents rare instances of Killer Whales (Orcinus orca) sharing freshly killed prey with humans.

Why are Killer Whales offering fresh prey to humans?

About Killer Whales (Orcinus orca):

  • Overview: Largest member of the dolphin family (Delphinidae), often called “wolves of the sea”.
  • Apex predators: At the top of the marine food chain.
  • Physical traits:
    • Black dorsal side, white underside, distinctive eye patch, saddle patch behind dorsal fin.
    • Can grow up to 9 m, weigh over 5,000 kg, and swim up to 54 km/hr.
  • Social structure: Live in pods led by a matriarch; highly coordinated hunters using complex tactics.
  • Distribution: Found in all oceans worldwide, from polar to tropical seas, in both open and coastal waters.
  • IUCN – Data Deficient: But many regional populations face threats from climate change, prey decline, and pollution.

Why do they offer their fresh prey to humans?

  • Study Findings (2004–2024):
    • Killer whales were observed offering whole prey to humans (fish, birds, mammals, etc.) in multiple oceans.
    • In most cases, they waited for a human response before reclaiming or abandoning prey.
  • Possible Reasons:
    • Exploration/Curiosity: Reflects their advanced cognition and social curiosity; a way to learn about humans.
    • Prosocial Behaviour: They are among the few species that share food within and outside their groups.
    • Play Theory Rejected: Behaviour not limited to juveniles; adults also involved, often with whole prey.
    • Scientific Thinking Analogy: Behaviour resembles “asking questions” and testing human reactions — a form of exploratory intelligence.
    • Machiavellian Behaviour: Could sometimes be manipulative, as killer whales are known to steal fish and disrupt vessels.

  • Courtship Function: Flashing used as mating signal; males emit species-specific codes, females respond if correct.

Ecological Role and Conservation Significance:

  • Sensitivity: Strongly affected by pesticides, habitat loss, artificial lights, and polluted water.
  • Habitat Health Indicator: Large synchronised gatherings reflect intact ecosystems; sparse numbers signal disturbance.
  • Light Pollution Impact: Artificial lighting disrupts flashing, forcing males to waste energy and reducing mating success.
  • Local Evidences: Communities like the Malasar and Irula report declines linked to pesticides and polluted streams.
  • Indicator Role: Act as proxy species for nocturnal biodiversity, signalling risks to moths, bats, and amphibians.
