CG HC upholds cancellation of Forest Rights of Villagers

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

Why in the News?

The Chhattisgarh High Court has dismissed a petition challenging the cancellation of Community Forest Rights (CFRs) granted to villagers of Ghatbarra in the Hasdeo Arand forest, an area where Adani Enterprises–linked coal mines operate.

Background of the Case:

  • Dispute Origin: The District-Level Committee (DLC) revoked CFR titles in 2016, citing that the area had already been diverted for mining in 2012 with MoEF clearance.
  • Petitioners’ Claim: The Hasdeo Arand Bachao Sangharsh Samiti argued that the Forest Rights Act (FRA), 2006 provides no revocation clause and that villagers were not given a fair hearing before cancellation.
  • Court’s View: The High Court upheld the State’s decision, calling the 2013 CFR grant a “mistake” void ab initio, and legally cancellable.

Key Judicial Findings:

  • Legality of Revocation: FRA lacks explicit revocation provision, but erroneous grants may be rectified; hence cancellation was valid.
  • Prior Approvals Prevail: 2012 MoEFCC mining clearance overrode subsequent CFR grants.
  • State Mineral Ownership: FRA does not affect the State’s control over minerals beneath forest land.
  • Locus Standi: Petitioners lacked standing after the Forest Rights Committee withdrew; no authorised village representation remained.
  • Suppression of Facts: Petitioners had earlier challenged land acquisition (case dismissed in 2022) but failed to disclose it.

Significance:

This ruling marks the first judicial interpretation of whether forest rights granted under the Forest Rights Act, 2006 (FRA) can be revoked or cancelled, despite the Act containing no explicit provision for cancellation.

About the Forest Rights Act (FRA), 2006:

  • Overview: The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, commonly called the Forest Rights Act (FRA).
  • Purpose: Enacted to correct historical injustices faced by forest-dwelling communities deprived of traditional land and resource rights during colonial rule.
  • Core Objective: Ensures tenurial security, livelihood protection, and ecological stewardship of forest-dependent populations.
  • Beneficiaries: Covers Scheduled Tribes (STs) and Other Traditional Forest Dwellers (OTFDs) who have lived in and depended on forests for generations.
  • Scope: Recognises both individual and collective rights over forest land and produce, extending to cultivation, habitation, and minor forest produce use.
  • Governance Principle: Empowers Gram Sabhas as the central authority for recognising and managing forest rights, reinforcing local autonomy.
  • Integration Goal: Aligns forest governance with tribal self-rule, complementing the Panchayats (Extension to Scheduled Areas) Act, 1996 (PESA).

Key Features of the FRA:

  • Individual & Community Rights: Legal recognition for occupation, cultivation, residence, and use/sale of minor forest produce.
  • Community Forest Resource (CFR) Rights: Grants Gram Sabhas control to protect, regenerate, and manage community forests.
  • Habitat Rights: Protects Particularly Vulnerable Tribal Groups (PVTGs) and pre-agricultural forest communities.
  • Governance Structure: Multi-level verification, Gram Sabha → Sub-Divisional Committee → District-Level Committee, for rights adjudication.
  • Development Provisions: Allows limited diversion of forest land for public utilities with Gram Sabha consent.
  • Eviction Safeguard: No eviction until claims are fully processed and rights recognised.
  • Decentralised Oversight: Empowers Gram Sabha as the final decision-making authority on forest rights and management.
  • Legal Integration: Reinforces PESA’s participatory governance and community-led conservation in Scheduled Areas.

Economic Indicators and Various Reports On It- GDP, FD, EODB, WIR etc

[16th October 2025 ] The Hindu Op-ed: Navigating the global economic transformation

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

PYQ Relevance

[UPSC 2019] The long-sustained image of India as a leader of the oppressed and marginalised nations has disappeared on account of its new found role in the emerging global order.

Linkage: The question reflects India’s shift from moral leadership to strategic pragmatism in global affairs. The article builds on this, urging India to reclaim that leadership by shaping a fair, inclusive global economic order for the Global South.

Mentor’s Comment

The tectonic shifts in the world economy today echo the reshaping of global power equations. Salman Khurshid’s article presents a comprehensive analysis of how populist politics, state capitalism, and digital colonialism are reshaping the global economic order. This piece unpacks those arguments and situates them in a UPSC-relevant analytical frame, connecting them to India’s strategic choices and the future of the Global South.

Introduction: Why in the News

The world economy is undergoing a seismic transformation, marked by the U.S.–China great-power rivalry, reshaped trade flows, and the rise of state-driven capitalism. This shift is more than cyclical; it is structural, redefining the principles of globalisation itself. For the first time in decades, both economic and political systems are converging towards protectionism and state control, breaking away from the neoliberal consensus that defined the post–Cold War era. The article underscores how these disruptions open a rare opportunity for India and the Global South to shape a fairer and more inclusive global economic order.

Understanding the New Economic Paradigms

How are populist autocrats reshaping capitalism?

  1. State–capital fusion: Populist autocrats have created a “state-capital Gordian knot”, replacing laissez-faire capitalism with systems that serve oligopolies in exchange for political loyalty.
  2. Corporate dominance: Crony-capitalists now influence state policies, prioritising corporate gains over citizen welfare — mortgaging public assets and weakening the social contract.
  3. Socio-political consequences: This model centralises power, marginalises public accountability, and distorts market competitiveness — leading to plutocracies, not democracies.

Why are traditional power politics resurfacing in the economic sphere?

  1. Resurgent statecraft: America’s recalibration to “Make America Great Again” marks a return of economic nationalism.
  2. Strategic control: U.S. actions — shifting Taiwan’s chip manufacturing, securing Panama routes, weaponising rare earths, and asserting dominance in the Arctic — reflect geo-economic containment of China.
  3. Ecological imperialism: By controlling supply chains and energy corridors, global powers are expanding influence under the guise of “strategic autonomy.”
  4. Global instability: These assertive spheres of influence have led to conflicts and genocides, reigniting the dangers of zero-sum geopolitics.

How is digital colonialism reshaping global economies?

  1. Big Tech dominance: Cloud capitalists have captured value chains and data flows, influencing politics and governance.
  2. Digital imperialism: Initiatives like the AI Action Plan, Cloud Act, and SWIFT weaponisation allow powerful states to dominate financial and cyber infrastructure.
  3. Erosion of sovereignty: Over 100 central banks are piloting state-backed digital currencies, which could ease transactions but risk undermining national autonomy.
  4. Political risks: Digital finance systems complicate political funding, giving populist regimes more tools for manipulation.

How have aid withdrawals widened global inequalities?

  1. Funding collapse: G-7 nations’ $44 billion cuts in developmental aid could push 5.7 million Africans into poverty by 2026.
  2. Ripple effects: In Nepal, reduced grants for small enterprises led to eight lakh migrations, intensifying domestic dissatisfaction.
  3. Humanitarian fallout: 16.7 million people lost access to the World Food Programme in 2023, sparking recruitment into militias across the Sahel region.
  4. Moral crisis: Retrenchment of aid reflects a shift from shared prosperity to self-preservation, amplifying instability in the Global South.

What challenges and opportunities emerge for India and the Global South?

  1. Debt and inequality: Neoliberal globalisation fostered sovereign debt traps and extreme wealth concentration in the Global North.
  2. Poverty crisis: The World Bank’s 2022 Poverty and Shared Prosperity Report notes 47% of humanity lives below the $6.85 poverty line, while 735 million suffer hunger.
  3. Collaborative alternatives: India and the Global South can construct a New Economic Deal through debt-relief frameworks, institutional reforms, and South–South cooperation.
  4. Strategic vision: Building bipartisan international ties and fair trade alliances through BRICS and regional groupings will ensure resilience against Western hegemony.

How must India recalibrate its domestic policies to lead globally?

  1. State leadership: The government must play a commanding role in strategic sectors — energy, data, infrastructure, healthcare, and agriculture — as done by East Asian economies.
  2. Anti-monopoly mechanisms: Creating sovereign wealth funds (like Norway) and enforcing anti-trust norms can prevent oligarchic dominance.
  3. Reimagining PSUs: Instead of privatisation, redeploying PSUs like China’s state-owned enterprises can serve national and geopolitical goals.
  4. Knowledge economy: Heavy investment in research, education, and innovation will secure India’s place as a globally competitive power.
  5. True non-alignment: India’s foreign policy must remain substantive, not performative — driven by consensus and independence rather than partisan interests.

Conclusion

The global economic transformation is not merely about trade or finance; it is about who controls the architecture of global interdependence. As old hierarchies fracture and new alignments emerge, India stands at a crossroads, between aligning with entrenched powers or leading a new era of equitable globalization. The coming decade will test whether the Global South can collectively author a future defined by justice, sustainability, and shared prosperity. The moment is precarious, but also profoundly promising.

The Crisis In The Middle East

The future of the IMEC

Explained | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

Introduction

In an era where connectivity defines power, the India–Middle East–Europe Economic Corridor (IMEC) emerged as a visionary project connecting India’s western ports with Europe via the Arabian Peninsula. Envisaged as a multi-modal corridor encompassing maritime, rail, energy, and digital infrastructure, IMEC sought to integrate economies across continents while promoting peace and prosperity in a historically volatile region.

However, the optimism that surrounded IMEC’s launch quickly met the harsh reality of geopolitics. The October 7 Hamas attacks and subsequent Israel–Gaza war exposed the fragility of West Asian stability, placing IMEC’s implementation in question. Yet, beyond the uncertainty lies an opportunity for India to reshape its connectivity vision, adapting routes and partnerships to new global dynamics.

Why in the News

The IMEC has resurfaced in policy discussions as its viability faces uncertainty amid the deteriorating West Asian security environment. The October 7 Hamas–Israel conflict disrupted regional optimism nurtured by the Abraham Accords and slowed progress on IMEC’s proposed transnational links. At the same time, climate-driven Arctic trade routes and Red Sea disruptions by the Houthis are redrawing global shipping patterns, forcing India and its partners to reconsider IMEC’s configuration. The issue is critical as the corridor represents both an economic and strategic counterweight to China’s Belt and Road Initiative (BRI).

The Strategic Vision Behind IMEC:

  1. Comprehensive Connectivity: IMEC aims to upgrade maritime routes between India and the Arabian Peninsula and establish high-speed rail links from UAE ports to Haifa, Israel, via Saudi Arabia and Jordan.
  2. Integration with Europe: From Haifa, goods would be shipped to Europe’s Mediterranean ports, ensuring faster, secure, and sustainable trade connectivity.
  3. Beyond Transport: The corridor also includes plans for a clean hydrogen pipeline, electricity cable, and high-speed undersea digital cable, linking energy and digital ecosystems across three continents.
  4. Strategic Objective: IMEC provides a non-Chinese, rules-based alternative to the Belt and Road Initiative (BRI), enhancing India’s strategic outreach and economic influence.

The Geopolitical Context of 2023:

  1. Favourable Climate: The Abraham Accords (2020) created optimism for regional peace, bringing Israel and several Arab states closer. This atmosphere facilitated multilateral cooperation frameworks such as I2U2 (India, Israel, UAE, U.S.), paving the way for IMEC.
  2. India’s Upward Trajectory: India’s improving ties with Saudi Arabia and the UAE, coupled with strong U.S. relations, allowed it to play a central role in IMEC’s conception.
  3. Global Endorsement: The corridor was launched at the G-20 Summit in Delhi, with support from the EU, France, Germany, Italy, and Saudi Arabia, underscoring India’s emergence as a trusted global partner.

The Security Setback and Regional Volatility

  1. Conflict Shock: Within weeks of IMEC’s announcement, the Hamas–Israel conflict erupted, reversing the post-Abraham optimism.
  2. Regional Fallout: Israel’s military operations strained ties with Arab countries, undermining cross-border infrastructure cooperation.
  3. Red Sea Disruptions: The Houthi attacks on cargo ships forced rerouting via the Cape of Good Hope, increasing transit time and cost.
  4. Lesson: The events underscore that geopolitical stability remains the cornerstone of connectivity, and corridors like IMEC must remain adaptable to shifting realities.

Europe’s Changing Maritime Interests

  1. Arctic Openings: Climate change has opened new northern sea routes, shortening Asia–Europe shipping times. Beneficiaries include Russia, the U.S., China, and northern European nations.
  2. Mediterranean Anxiety: Countries like Italy, dependent solely on the Mediterranean, fear economic marginalisation if Arctic routes dominate trade.
  3. Strategic Importance of IMEC: Hence, Mediterranean states see IMEC as a means to sustain their maritime relevance and diversify trade partnerships.
  4. India’s Role: For India, the Mediterranean remains vital, as Arctic routes offer no immediate logistical advantage.

Why IMEC Still Matters for India

  1. Economic Scale: With $136 billion in annual trade, the EU remains India’s largest trading partner, highlighting the need for resilient connectivity.
  2. Supply Chain Resilience: IMEC offers a secure, shorter route connecting India to Europe while reducing dependence on the Red Sea–Suez chokepoint.
  3. Strategic Leverage: Enhanced engagement with Arab economies can dilute Pakistan’s influence and integrate India deeper into West Asia’s economic architecture.
  4. Innovation Space: As a multi-member initiative, IMEC allows India to propose new routes via Saudi Arabia and Egypt, adapting to political flux.

Challenges and the Way Forward

  1. Security Dependencies: Ongoing instability in Gaza and Israel poses a persistent threat.
  2. Financial and Political Coordination: Multi-country infrastructure projects face coordination delays, regulatory inconsistencies, and funding constraints.
  3. Need for Parallel Efforts: India must also upgrade domestic ports and logistics infrastructure, including Sagarmala and Dedicated Freight Corridors, to complement IMEC.
  4. Diplomatic Continuity: Sustaining dialogue through I2U2 and G-20 cooperation can help preserve IMEC’s spirit even if its routes evolve.

Conclusion

The IMEC’s future will depend not merely on the pacification of West Asia but on the political agility and diplomatic imagination of its members. While the corridor’s physical routes may shift, its strategic essence remains intact, to build resilient, diversified, and sustainable connectivity between India and Europe. For India, IMEC is more than an infrastructure project; it is a statement of intent, to be at the centre of global supply chains and a stabilising power in a fractured world.

PYQ Relevance

[UPSC 2018] The China-Pakistan Economic Corridor (CPEC) is viewed as a cardinal subset of China’s larger ‘One Belt One Road’ initiative. Give a brief description of CPEC and enumerate the reasons why India has distanced itself from the same.

Linkage: While China’s CPEC runs through disputed territory, making India wary, the IMEC shows how India is building its own clean, safe, and cooperative route to connect with Europe. It’s India’s way of staying in the global connectivity game—on its own terms.

Renewable Energy – Wind, Tidal, Geothermal, etc.

The critical factor in India’s clean energy ambition

Explained | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.

Introduction

India’s ambition to achieve 500 GW of renewable energy by 2030 and net zero emissions by 2070 depends not just on sunlight and wind but on minerals buried beneath the earth’s surface. Lithium, cobalt, and REEs form the backbone of technologies driving the clean energy revolution. However, India imports almost all of these minerals, exposing its renewable future to external shocks. The article explores how India is gearing up to build a resilient supply chain, promote domestic mining, and move toward a circular economy, turning its green dreams into a self-reliant reality.

India’s Clean Energy Journey and the Mineral Imperative

  1. Critical minerals as enablers: They power EV batteries, solar panels, and wind turbines, the pillars of the green transition.
  2. Explosive market growth: India’s EV market is projected to grow at a 49% CAGR from 2023 to 2030, driven by the Electric Mobility Promotion Scheme (EMPS) 2024.
  3. Battery boom: The battery storage market, valued at $2.8 billion in 2023, is set to surge with renewable energy integration.
  4. Import dependency: India currently imports nearly 100% of lithium, cobalt, and nickel, and over 90% of REEs, creating severe strategic vulnerabilities.

Why Dependence is Dangerous: Global Supply Chain Vulnerabilities

  1. China’s dominance: Controls 60% of global REE production and 85% of processing capacity, giving it massive leverage.
  2. Geopolitical risks: Trade restrictions, conflicts, and supply disruptions can derail India’s energy transition plans.
  3. National security angle: Critical minerals are not just about clean energy,  they are strategic assets influencing defence, technology, and economic sovereignty.

India’s Domestic Potential: A Hidden Treasure Beneath the Soil

  1. New discoveries: The Geological Survey of India (GSI) identified 5.9 million tonnes of inferred lithium in Jammu & Kashmir in 2023, a major breakthrough.
  2. Policy push: The National Mineral Exploration Policy (NMEP), 2016, and amendments to the Mines and Minerals (Development and Regulation) Act, 2021, opened up exploration to private players.
  3. Auctions driving interest: In 2023 alone, 20 critical mineral blocks (lithium, graphite, REEs) were auctioned, attracting domestic and multinational bidders.
  4. Potential-rich states: Jammu & Kashmir, Rajasthan (lithium), Odisha, and Andhra Pradesh (REEs) have emerged as mineral hotspots.

From Discovery to Refinement: The Missing Link

  1. Production bottleneck: India contributes less than 1% of global REE production due to weak refining and processing infrastructure.
  2. Need for partnerships: Public-private collaborations can bring in advanced processing technologies and recycling systems.
  3. Government incentives: Subsidies, tax breaks, and R&D grants are critical to scale domestic lithium and cobalt pilot projects.

Investment and Policy Momentum: Building the Foundation

  1. Regulatory reforms: The Mines and Minerals (Amendment) Act, 2023 allows private exploration but the sector faces high costs and environmental concerns.
  2. Economic potential: Mining contributes only 2.5% to India’s GDP, compared to 13.6% in Australia — signalling untapped opportunity.
  3. National Critical Mineral Mission (NCMM): With an outlay of ₹34,300 crore, it aims to strengthen the value chain — from exploration to recycling.

Institutional efforts:

  1. NMDC diversifying through its Australian arm.
  2. IREL (India) Ltd. extracting REEs like neodymium, praseodymium, and dysprosium.
  3. KABIL (Khanij Bidesh India Ltd.), formed in 2019, tasked with overseas acquisitions of mineral assets.

Moving Towards a Circular Economy

  1. E-waste as opportunity: India produces 4 million metric tonnes of e-waste annually, yet only 10% is formally recycled.
  2. Recycling policies: The Battery Waste Management Rules (2022) and E-Waste Management Rules (2022) aim to improve recovery of critical minerals.
  3. Challenges: Weak enforcement, poor infrastructure, and lack of awareness hinder progress.
  4. Way forward: Public-private recycling hubs can boost technology access, cut costs, and reduce environmental footprint, paving the way for a circular economy.

Conclusion

Critical minerals are the backbone of India’s clean energy transformation. Securing them is not just about green growth, but about economic independence and strategic security. India’s policy thrust through the National Critical Mineral Mission, domestic auctions, and recycling reforms signal intent, but execution remains key. A coherent strategy involving private investment, state backing, and global partnerships can ensure India does not just consume green technology, it creates it. The success of this mission will determine whether India emerges as a leader in the global clean energy race or remains dependent on others for its green dreams.

PYQ Relevance

[UPSC 2022] Do you think India will meet 50 percent of its energy needs from renewable energy by 2030? Justify your answer. How will the shift of subsidies from fossil fuels to renewables help achieve the above objective?

Linkage: India’s ability to meet 50% of its energy needs from renewables by 2030 hinges on securing critical minerals like lithium and REEs that power solar, wind, and EV technologies. A shift of subsidies from fossil fuels to renewables will accelerate domestic mining, recycling, and innovation—building the self-reliant green infrastructure essential for achieving this target.

Foreign Policy Watch: India-Australia

[15th October 2025 ] The Hindu Op-ed: Powering up the Australia-India clean energy partnership

op-ed snap | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

PYQ Relevance

[UPSC 2022] Clean energy is the order of the day. Describe briefly India’s changing policy towards climate change in various international fora in the context of geopolitics.

Linkage: The India–Australia Renewable Energy Partnership (REP) exemplifies India’s evolving climate diplomacy — shifting from being a climate “follower” to a global clean energy collaborator. It reflects how India aligns geopolitical strategy with green transition, using partnerships like REP to ensure both sustainability and supply chain autonomy.

Mentor’s Comment

At a time when the world is rethinking its clean energy priorities amidst climate vulnerabilities and geopolitical flux, the Australia–India Renewable Energy Partnership (REP) emerges as a beacon of cooperative strength. This article examines how two Indo-Pacific democracies can forge a resilient, balanced, and future-ready clean energy ecosystem — turning climate ambition into implementable strategy.

Introduction

In a decade defined by climate urgency and energy transition, India and Australia are deepening collaboration in renewable energy to reduce carbon footprints and diversify critical supply chains. With Australia’s Climate Change and Energy Minister Chris Bowen visiting New Delhi, both nations are poised to convert their shared climate vision into tangible outcomes under the India–Australia Renewable Energy Partnership (REP). The partnership arrives at a pivotal moment when the Indo-Pacific region is reeling under frequent climate disasters and when overdependence on China for clean energy inputs threatens energy security.

Why This Is Big News

The India–Australia clean energy partnership represents a strategic shift from bilateral intent to operational collaboration. It marks the first large-scale joint response by the two democracies to build resilient, China-independent supply chains for renewable technologies.

This is significant because the Indo-Pacific averages nearly 10 climate disasters per month, and projections show up to 89 million climate refugees by 2050. Both countries now aim not merely for targets but for structural autonomy in critical minerals, hydrogen, and solar ecosystems — signalling a new phase of climate diplomacy.

A Climate-Vulnerable Region

  1. Harshest impacts: The Indo-Pacific region witnesses some of the world’s most severe climate consequences, with recurring floods, cyclones, and droughts.
  2. Alarming projections: Between 1970–2022, it averaged 10 climate-related disasters monthly; by 2050, 89 million people may be displaced.
  3. India’s leadership: India targets 500 GW of non-fossil electricity by 2030 (with 280 GW solar) and has achieved 50% non-fossil capacity already — five years ahead of schedule.
  4. Australia’s climate push: It has raised its emission-reduction ambition to 62–70% below 2005 levels by 2035, aligning with its net-zero goal.

The Supply Chain Challenge

  1. Dependence on China: China refines 90% of rare earth elements and manufactures 80% of global solar modules, giving it near-monopoly power.
  2. India’s dilemma: Faces import dependence for rare earth magnets and battery materials, affecting EV and wind sectors.
  3. Australia’s gap: Despite being rich in lithium, cobalt, and rare earths, it lacks refining and downstream industries.
  4. Pandemic exposure: The COVID-19 crisis exposed global supply fragility; China’s export restrictions further underlined the danger of single-country dependence.
  5. Industry impact: Example, an Indian EV manufacturer’s production halved in July due to component shortages.

What the Renewable Energy Partnership (REP) Offers

  1. Comprehensive framework: REP spans eight key areas, solar PV, green hydrogen, energy storage, circular economy, solar supply chains, two-way investments, and capacity building.
  2. Collaborative platforms: Introduces a Track 1.5 Dialogue, connecting policy, industry, and academia to translate ideas into pilot projects.
  3. Focus areas: Promotes joint R&D, investment in refining, hydrogen economy, and cross-training of skilled personnel.
  4. Strategic significance: Seeks to create an Indo-Pacific clean energy hub resilient to geopolitical shocks.

Complementary Strengths: Why Collaboration Works

Australia’s edge:

  1. Critical mineral base — rich in lithium, rare earths.
  2. Stable regulations and a focus on green jobs under its Net Zero Jobs Plan.

India’s advantage:

  1. Demographic dividend — 65% population below 35 years.
  2. PLI schemes and Skill India fostering clean-tech manufacturing.
  3. Expanding domestic demand for solar, hydrogen, and battery systems.

Synergistic model: Together, they can integrate Australia’s minerals with India’s manufacturing and labour pool, creating a regional clean energy ecosystem that is both inclusive and secure.

Why This Partnership Matters for the Indo-Pacific

  1. Climate resilience: Joint efforts show that democracies can lead energy transitions without autocratic dependencies.
  2. Geopolitical signalling: It strengthens Quad cooperation (India–Australia–Japan–US) by aligning clean energy goals.
  3. Economic dividends: Builds green value chains that can generate jobs and diversify trade beyond fossil fuels.

Conclusion

The Australia–India Renewable Energy Partnership is more than a bilateral initiative, it is a climate-security compact for the Indo-Pacific. By combining Australia’s resource advantage with India’s innovation and manpower, both nations can anchor a sustainable energy future independent of geopolitical coercion. In doing so, they not only contribute to global net-zero targets but also demonstrate how democratic collaboration can address shared vulnerabilities with foresight and resilience.

Nobel and other Prizes

How innovation drives economic growth

Explained | Economics | Mains Paper 3: Issues relating growth and development, employment

Introduction

The 2025 Sveriges Riksbank Prize in Economic Sciences was awarded to Joel Mokyr, Philippe Aghion, and Peter Howitt for “explaining innovation-driven economic growth.” Their research collectively answers one of the most fundamental economic puzzles — how nations sustain growth over centuries, not decades.

Why in the News

The Nobel Committee’s decision is significant because it celebrates innovation as the engine of sustained prosperity at a time when economies face stagnation despite technological abundance. It also marks a historical synthesis, combining Mokyr’s economic history with Aghion and Howitt’s modern growth models, to offer a unified vision of why the last two centuries broke free from millennia of stagnation. This award underscores that knowledge creation and openness to change are as critical to a nation’s future as natural resources or fiscal policy.

Understanding the Foundations of Innovation-Driven Growth

What did Joel Mokyr’s research reveal about sustained growth?

  1. Useful Knowledge: Mokyr argued that long-term growth depends on a constant flow of useful knowledge, divided into propositional (theoretical understanding) and prescriptive (practical implementation) forms.
  2. Before Industrial Revolution: Innovators understood why things worked (propositional) but lacked the technical ability to make them work (prescriptive).
  3. Scientific Revolution Impact: The 16th–17th centuries brought controlled experiments and reproducibility — transforming knowledge from abstract to applicable.
  4. Policy Implication: Nations must ensure technical education and skill development, as ideas alone cannot yield growth without implementation.

How did Mokyr link innovation to social openness?

  1. Openness to Change: Innovation often disrupts existing systems and creates losers; societies resistant to change stifle progress.
  2. Historical Example: Britain’s sustained growth stemmed from skilled artisans and engineers who translated scientific ideas into industrial applications.
  3. Policy Lesson: Governments must create inclusive ecosystems that accept change, retrain workers, and redistribute gains from innovation.

What is the Theory of Creative Destruction?

  1. Conceptual Core: Originally introduced by Schumpeter, “creative destruction” describes how innovation replaces older technologies and firms, creating both winners and losers.
  2. Aghion & Howitt’s Contribution: They formalized this process mathematically, showing how technological progress leads to sustained long-term growth.
  3. Dynamic Equilibrium: Innovation raises productivity but simultaneously displaces outdated industries — a perpetual cycle that fuels development.

How much should a country invest in Research and Development (R&D)?

  1. Balancing Act: Aghion and Howitt’s model shows two opposing trends:
    1. Trend 1 — Underinvestment: Since society benefits from outdated technologies even after firms lose profits, R&D should be subsidized to ensure social spillovers.
    2. Trend 2 — Overinvestment: When incremental innovations capture disproportionate profits, R&D may be excessive and distort competition.
  2. Optimal Level: There is no universal ideal investment, but the model provides tools to identify an economy-specific optimum that maximizes welfare without creating monopolistic inefficiencies.

Why does this Nobel matter for developing economies like India?

  1. Knowledge Ecosystem: The laureates’ findings emphasise that growth requires not just innovation, but translation — turning ideas into scalable realities through skills, entrepreneurship, and openness.
  2. India’s Imperative: Investments in R&D (currently ~0.7% of GDP), vocational skilling, and ease of doing business are crucial to realize the demographic dividend.
  3. Policy Relevance: The Economic Survey and NITI Aayog’s “Innovation Index” already underline similar principles — this Nobel reinforces India’s need to build a “knowledge economy.”

Conclusion

The 2025 Nobel Prize in Economic Sciences reaffirms that innovation, knowledge, and societal openness are the real engines of prosperity. Economic success is no longer a product of mere capital or labor, but of the synergy between imagination and execution. For India and other developing nations, the message is clear: sustained growth depends on nurturing human capital, research ecosystems, and tolerance for disruption. As Mokyr’s and Aghion–Howitt’s work shows, societies that embrace change, skill their people, and invest in ideas will lead the next chapter of human progress.

Foreign Policy Watch: India-Afghanistan

Complacity not diplomacy-India’s engagement with Taliban

Explained | International Relations | Mains Paper 2: India & Its Neighborhood - Relations

Introduction

The exclusion of women journalists from Taliban press conferences in New Delhi was not an accident, it was symbolic of a deeper issue: legitimizing a regime whose ideology is built on the deliberate erasure of women’s existence. As Afghan women face persecution, violence, and disappearance from every public sphere, the silence of democratic nations like India risks validating gender apartheid.

Why is this issue in the news?

The controversy erupted when India hosted two Taliban press conferences in New Delhi, where female journalists were initially excluded. The event coincided with a People’s Tribunal on the Women of Afghanistan in Madrid, where survivors testified to the Taliban’s gender-based persecution, recognized as a crime against humanity. The contrast between India’s engagement and the global condemnation of Taliban policies underscores a moral and diplomatic crisis.

How has the Taliban institutionalized the erasure of women?

  1. Systematic exclusion: Since their 2021 return, the Taliban banned women from most public-sector jobs, secondary schools, and universities.
  2. Legalized oppression: The 2024 Propagation of Virtue and Prevention of Vice Law formally declared women’s voices “forbidden” in public.
  3. Economic silencing: A 2025 Afghanistan Media Support Organisation survey found that 93% of women journalists lost their jobs, with more than 42% leaving journalism altogether.
  4. Violence and fear: Women activists are detained, beaten, and their husbands tortured, part of a deliberate campaign to erase their visibility and livelihood.

Why is India’s stance seen as complicit rather than diplomatic?

  1. Normalization of misogyny: Hosting Taliban officials while Afghan women pleaded for recognition signals tacit acceptance of their regime.
  2. Moral inconsistency: While democracies like Spain and Canada host tribunals condemning Taliban atrocities, India’s diplomatic outreach stands in stark contrast.
  3. Diplomatic short-sightedness: By engaging the Taliban without human rights conditionalities, India risks legitimizing gender apartheid as a form of governance.

What does this reveal about the global response to women’s rights?

  1. Erosion of feminist diplomacy: Nations increasingly prioritize geopolitical pragmatism over gender justice.
  2. Media complicity: Even in New Delhi, the Taliban’s media interaction mirrored their exclusionary ethos, showing that patriarchal silencing transcends borders.
  3. Selective outrage: While Western nations condemn the Taliban, many still negotiate covertly for strategic or security reasons, diluting international accountability.

What lessons does this hold for India’s foreign policy and democracy?

  1. Moral leadership deficit: India’s silence undermines its self-image as the voice of the Global South and defender of democratic rights.
  2. Gender and diplomacy linkage: True diplomacy must integrate gender-sensitive ethics, ensuring no engagement legitimizes systemic violence.
  3. Internal reflection: A democracy’s foreign policy mirrors its domestic respect for women’s agency. India’s global credibility depends on aligning words with action.

Conclusion 

India’s engagement with the Taliban marks a dangerous shift from moral diplomacy to moral compromise. As Afghan women’s rights are being erased, India’s silence echoes complicity, not neutrality. True diplomacy must speak truth to power, not share its platform. Democracies cannot afford to normalize gender apartheid; silence here is not strategy, it is surrender.

PYQ Relevance

[UPSC 2013] The proposed withdrawal of the International Security Assistance Force (ISAF) from Afghanistan in 2014 is fraught with major security implications for the countries of the region. Examine in light of the fact that India is faced with a plethora of challenges and needs to safeguard its own strategic interests.

Linkage: India’s current engagement with the Taliban reflects the security vacuum created after the ISAF withdrawal, forcing New Delhi to balance strategic interests with moral responsibility. As the article shows, this has turned India’s Afghan policy from cautious realism into a test of its ethical diplomacy and regional credibility.

Back2Basics: Gaganyaan Mission:

  • Overview: India’s first human spaceflight mission, initiated in 2007, to send 3 astronauts into Low Earth Orbit (400 km) for 3 days, followed by Arabian Sea splashdown.
  • Rocket: Human-Rated LVM3 (HLVM3), adapted from GSLV Mk3, certified in 2025 for safe human use.
  • Significance: India to become the 4th nation (after US, Russia, China) with crewed spaceflight capability.
  • Latest Timeline (as of Sept 2025):
    • Dec 2025: First uncrewed mission (G1) with humanoid Vyommitra.
    • 2026: Two more uncrewed flights for life-support, avionics, and escape tests.
    • Early 2027: First crewed mission – 3 astronauts in orbit for 3 days.
  • Progress so far:
    • 80–85% development complete: avionics, parachutes, crew safety systems validated.
    • Integrated Air Drop Test (Aug 2025): Confirmed crew module deceleration.
    • Crew Escape System: Multiple ground and flight tests successful.
    • Recovery: Indian Navy and Australian Space Agency conducting splashdown drills.
    • Four IAF test pilots shortlisted: Shubhanshu Shukla, Prasanth Balakrishnan Nair, Angad Pratap, Ajit Krishnan.
    • All trained in Russia, now in advanced Indian training. Final crew of three will be chosen for maiden flight.

What is Crew Escape System (CES)?

  • Purpose: A critical safety mechanism in ISRO’s Gaganyaan Mission, enabling astronaut rescue in case of launch vehicle failure during the atmospheric ascent phase.
  • Placement & Function: Mounted atop the Human-Rated LVM3 (HLVM3) rocket; rapidly separates the crew module and propels it to safety using high-thrust solid motors.
  • Performance: Escape motors generate acceleration up to 10 g, using high burn-rate propellants for faster thrust than the launcher. Astronauts withstand this briefly in a “child-in-cradle” posture.
  • Safety Systems: Incorporates redundant subsystems, heritage-based design, and real-time health monitoring through the Integrated Vehicle Health Management (IVHM) network for millisecond-level response.
  • Types of CES:
    1. Puller-Type: Used in Gaganyaan; solid-fuel motors pull the crew module away. Also adopted by Russia’s Soyuz, China’s Long March, and US Saturn V missions.
    2. Pusher-Type: Used in SpaceX Crew Dragon (Falcon 9); liquid-fuel thrusters push the capsule away.
  • Comparison: Puller systems suit high-thrust, short-duration extractions; pusher systems integrate better with reusable modules.

Operational Sequence & Recovery:

  1. Automatic Activation: On anomaly detection, IVHM triggers CES instantly; escape motors fire, propelling the crew module clear of the rocket.
  2. Separation & Descent: After reaching safe distance, CES detaches and the module descends under multistage parachutes, drogue, main, and reserve, ensuring controlled speed and stability.
  3. Splashdown & Safety: The module lands in the sea, impact forces within safe physiological limits, allowing quick recovery.
  4. Significance: Serves as the core life-saving system of India’s human spaceflight programme, ensuring crew survival during catastrophic launch failures.

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

What are Climate Tipping Points?

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

Why in the News?

The Global Tipping Points Report (2025), authored by 160 scientists from 23 countries, warns that warm-water coral reefs have already crossed their thermal tipping point, triggering irreversible dieback.

About Tipping Points:

  • Overview: Tipping Points are critical thresholds in Earth’s natural and climate systems beyond which self-reinforcing and often irreversible changes occur.
  • Mechanism: Once crossed, feedback loops accelerate transformation — e.g., melting permafrost releases methane, which increases warming and causes more melting.
  • Irreversibility: Even if greenhouse gas emissions are later reduced, many systems cannot revert to their original stable state.
  • Significance: Tipping Points determine long-term planetary stability, climate predictability, and biosphere resilience.

Important Definitions:

  • Climate Tipping Point (IPCC): A critical threshold at which small changes in temperature or forcing cause a large, often irreversible shift in a climate subsystem.
  • Feedback Loop: A process where an initial change triggers further effects that amplify the original disturbance (positive feedback).
  • Hysteresis: The property of a system where reversing to its prior state requires conditions much different from those that caused the initial change.
  • Cascade Effect: A phenomenon where crossing one tipping point triggers others in connected Earth systems, leading to compounded impacts.
  • Thermal Tipping Point (for Coral Reefs): The temperature threshold (~1.2°C above pre-industrial) beyond which coral survival and recovery become impossible.

Key Global Tipping Points Identified:

  • Ice Sheets: Collapse of Greenland and West Antarctic ice sheets, committing the planet to multi-metre sea-level rise.
  • Coral Reefs: Permanent dieback of warm-water reefs due to ocean warming and acidification, destroying marine biodiversity.
  • Amazon Rainforest: Shift toward a savannah ecosystem, reducing carbon storage and regional rainfall.
  • Atlantic Meridional Overturning Circulation (AMOC): Potential shutdown below 2°C, disrupting global heat distribution and monsoon patterns.
  • Permafrost Thaw: Release of methane and CO₂, reinforcing global warming.
  • Boreal Forests & Mountain Glaciers: Increased risk of widespread dieback and loss of freshwater reserves.
  • Sub-Polar Gyre (SPG): Destabilization in North Atlantic circulation, altering marine ecosystems and heat flow.

Highlights from the Latest Reports (Global Tipping Points 2025):

  • Study Scale: Conducted by 160 scientists from 23 countries, assessing multiple Earth-system thresholds.
  • Coral Crisis: Since January 2023, 84.4% of coral reefs across 82 nations have suffered bleaching — marking the fourth global mass event, the worst on record.
  • Temperature Thresholds: Exceeding 1.5°C global warming risks triggering multiple tipping points; 1.2°C already breached for warm-water reefs.
  • AMOC Collapse Risk: Could occur below 2°C, potentially plunging northwest Europe into severe winters and disrupting global food and water systems.
  • Amazon Dieback: Widespread collapse possible below 2°C, directly affecting 100+ million people dependent on its ecosystem.
  • Interconnected Risk: Earth’s systems form a tipping network — crossing one threshold may accelerate others, creating a domino-like cascade.
  • Policy Warning: Current Paris Agreement pledges and net-zero targets are inadequate to limit warming below 2°C.
[UPSC 2024] One of the following regions has the world’s largest tropical peatland, which holds about three years’ worth of global carbon emissions from fossil fuels, and the possible destruction of which can exert a detrimental effect on the global climate.

Why in the News?

The successful trial of India’s first hydrogen-powered coach at the Integral Coach Factory (ICF), Chennai, in July 2025 marks a critical milestone in the Indian Railways’ decarbonisation strategy.

Introduction:

With a target of achieving net-zero carbon emissions by 2030, four decades ahead of India’s national goal, the Indian Railways is reshaping its energy, infrastructure, and financing architecture to become a global model for sustainable mobility.

Carrying over 24 million passengers and 3 million tonnes of freight daily, this transition directly supports India’s nationally determined contributions (NDCs) under the Paris Agreement.

India’s Energy Transition Context (2025):

  • As of June 2025, over 50% of India’s installed power capacity (476 GW total) comes from non-fossil sources, five years ahead of its 2030 Paris target.
  • Renewables: Solar (110.9 GW) and wind (51.3 GW) continue rapid expansion; nuclear capacity adds 8.8 GW.
  • Electrification: 100% village electrification achieved, with household access nearing universality.
  • Challenges:
    • Fossil fuel reliance: Coal consumption rose to 21.98 EJ in 2023, up from 6.53 EJ in 1998, with petroleum demand increasing in agriculture.
    • Energy equity gaps: Access to clean cooking fuel remains uneven; LPG adoption under PM Ujjwala Yojana suffers from affordability constraints.

Green Transition and Decarbonisation Efforts in Railways:

  1. Network Electrification: Over the past decade, the Indian Railways has electrified nearly 45,000 km of its broad-gauge network, bringing 98% of routes under electrification. This has drastically reduced diesel use and greenhouse gas emissions, marking a major shift toward energy efficiency.
  2. Renewable Integration: Renewable power capacity has reached 756 MW (553 MW solar, 103 MW wind, 100 MW hybrid). Over 2,000 stations and offices are now powered by solar energy, reducing grid dependence and promoting clean traction power.
  3. Net-Zero Buildings: Several railway complexes and offices have received the “Shunya” Net-Zero label from the Bureau of Energy Efficiency (BEE) for achieving energy neutrality and carbon efficiency.
  4. Hydrogen for Heritage Initiative: This flagship programme aims to deploy 35 hydrogen-powered train units, with the first prototype hydrogen coach rolled out in 2025, representing a major milestone in green rail mobility.
  5. Freight and Efficiency Gains: Dedicated Freight Corridors (DFCs) are projected to prevent 457 million tonnes of CO₂ emissions over the next 30 years. The goal is to increase the rail freight modal share from 27% to 45% by 2030, cutting road-sector emissions.
  6. Complementary Actions: Railways are also expanding biofuel blending, green building construction, and rolling stock modernisation with regenerative braking and energy-efficient locomotives.

Hydrogen Coach Technology and Innovation:

  1. Fuel-Cell Mechanism: The hydrogen coach uses fuel-cell technology to generate electricity through a chemical reaction between hydrogen and oxygen, producing only water vapour as the by-product, ensuring zero tailpipe emissions.
  2. Operational Context: Designed for non-electrified heritage routes where full electrification is uneconomical, these trains combine lightweight coach design, aerodynamic efficiency, and AI-based traction optimisation to minimise operational costs.
  3. Global Positioning: With this innovation, India joins the league of nations such as Germany and Japan that are pioneering hydrogen-based railway systems as part of a wider low-carbon transport transition.

Climate Finance and Institutional Architecture:

  1. Green Financing Framework: India has issued ₹58,000 crore worth of sovereign green bonds since FY2023, with ₹42,000 crore specifically allocated to electric locomotives, metros, and suburban rail projects.
  2. IRFC’s Role: The Indian Railway Finance Corporation (IRFC) pioneered a $500 million green bond in 2017 for refinancing electric locomotive projects, and in 2025 extended a ₹7,500 crore loan to NTPC Green Energy to support renewable generation for traction power.
  3. Multilateral Support: The World Bank’s $245 million Rail Logistics Project (2022) aims to decongest corridors and reduce transport-sector emissions through improved infrastructure efficiency.
  4. Institutional Integration: Together, these instruments embed climate goals into national capital budgeting, aligning transport infrastructure with India’s low-carbon growth pathway.

Policy and Operational Priorities:

  1. Renewable Power Procurement: Long-term contracts with solar and wind producers are critical to ensure that electrified routes are powered by green energy rather than coal-based electricity.
  2. Green Mobility Hubs: Major stations are being redesigned as multi-modal eco-hubs with integration of EV charging stations, e-buses, and bicycle-sharing systems.
  3. Freight Decarbonisation: Emphasis on electric, LNG, and hydrogen-fuelled trucks for last-mile logistics, reducing the carbon footprint beyond rail.
  4. Rolling Stock Modernisation: Accelerated adoption of lightweight aluminium coaches, regenerative braking, and energy-efficient locomotives.
  5. Behavioural Initiatives: Introduction of green certification for trains, carbon labelling of freight, and public awareness programmes to mainstream sustainability.

Projected Outcomes by 2030:

  1. Net-Zero Achievement: The Indian Railways aims to achieve net-zero carbon emissions by 2030, preventing an estimated 60 million tonnes of CO₂ annually, equivalent to removing 13 million cars from the roads.
  2. Economic Impact: Fuel cost savings from electrification and energy efficiency could exceed ₹1 lakh crore by 2030, freeing capital for further green infrastructure.
  3. Global Benchmark: The Indian Railways is positioned to become the world’s first large rail system to achieve net-zero operations, setting a global precedent for state-run low-carbon transport.

Conclusion:

  1. The hydrogen-powered coach exemplifies the synergy of technology, finance, and policy in achieving sustainable national mobility.
  2. The Railways’ green transformation is both an environmental necessity and a strategic innovation model for the developing world.
  3. Its successful execution will anchor India’s net-zero and green industrialisation vision, proving that scale and sustainability can coexist profitably.

Delhi Morphological Ridge

Prelims Only | Geography | Mains Paper 1: Geographical Features & Their Location

Why in the News?

The Delhi government has decided to declare 41 sq. km of the Southern Ridge as a reserved forest under the Indian Forest Act, 1927, following long-pending directions from the National Green Tribunal (NGT).

Delhi Morphological Ridge

About Delhi Morphological Ridge:

  • The Delhi Ridge is the northern extension of the ancient Aravalli Range, stretching approximately 35 km from Tughlaqabad to Wazirabad, along the Yamuna River.
  • It is composed mainly of quartzite rock, is over 1.5 billion years old, and significantly older than the Himalayas.
  • It functions as Delhi’s green lungs, aiding in carbon sequestration, temperature regulation, and air pollution reduction.
  • It acts as a natural barrier against desert winds from Rajasthan and supports rich biodiversity, making Delhi one of the world’s most bird-rich capitals.
  • It is divided into four zones: Northern Ridge, Central Ridge, South-Central Ridge, and Southern Ridge.
  • Key conservation areas include the Northern Ridge Biodiversity Park and the Asola Bhatti Wildlife Sanctuary.

Land Use Regulation in the Ridge:

  • Although the area shares ecological features with the Delhi Ridge, it is NOT officially notified as forest land, but it enjoys judicial protection.
  • A 1966 directive prohibits any NON-forest use or encroachment without court approval.
  • Any change in land use must be cleared by the Ridge Management Board (RMB) and the Supreme Court-appointed Central Empowered Committee (CEC).
  • The area is mapped using data from the Delhi Forest Department and the 2006 Seismic Zonation Map.
  • Formal notification as a Reserved Forest under the Indian Forest Act, 1927, is pending due to the absence of ground-truthing.
  • In revenue records, it is often marked as “gair mumkin pahad”, meaning uncultivable rocky hill.
  • The terrain is ecologically fragile, with shallow soil and rocky outcrops, making it unsuitable for construction.
