Paper: GS-II (Indian Polity, Parliament and State Legislatures, Elections)
UPSC Relevance: ★★★★★ (Very High)
Why in News?
On September 25, 2026, the Union Cabinet formally approved the phase-wise implementation roadmap for the ‘One Nation, One Election’ (ONOE) framework. Based on the final recommendations of the High-Level Committee, the government aims to synchronize the Lok Sabha and State Assembly elections by the 2029 electoral cycle.
Understanding the Electoral Transition
Historically, simultaneous elections were the norm in India until 1967, after which premature dissolutions of State Assemblies disrupting the cycle. The ONOE framework seeks to amend the Constitution to synchronize the terms of the State Assemblies with the Lok Sabha. If a State Assembly is dissolved prematurely, the new assembly will only serve the “remainder of the term” rather than a full five-year term, ensuring the simultaneous cycle remains unbroken.
Key Pillars of the Implementation Framework
| Thematic Pillar | Key Initiatives & Focus Areas |
| Constitutional Amendments | Introduction of Article 324A for unified electoral rolls and amending Article 83 (Duration of Houses of Parliament) and Article 172 (State Legislatures). |
| The Transition Phase | A one-time curtailment or extension of current State Assembly tenures to align them with the 2029 Lok Sabha elections. |
| Logistics and EVMs | Authorization of ₹15,000 crore to the Election Commission of India (ECI) for the procurement of additional EVMs and VVPATs required for simultaneous voting. |
| Local Body Synchronization | A proposed Phase-II where Panchayat and Municipal elections will be held within 100 days of the national and state elections. |
Strategic Significance
- Massive Cost Reduction: Frequent elections drain the exchequer. ONOE will drastically consolidate the staggering logistics, security deployment, and administrative costs.
- Policy Continuity: Prevents the frequent imposition of the Model Code of Conduct (MCC), which routinely stalls developmental projects and welfare schemes.
- Focus on Governance: Relieves the political executive from being in a “perpetual campaign mode,” allowing for long-term policymaking.
Key Challenges in Implementation
- Federalism Concerns: Several regional parties argue that national issues will overshadow local state-level issues, putting regional parties at an electoral disadvantage.
- Requirement of Ratification: The amendments require passage by a two-thirds majority in Parliament and ratification by at least half of the State Legislatures, posing a massive political hurdle.
- No-Confidence Motions: If a government falls mid-term, conducting fresh elections only for the “remainder of the term” might lead to voter fatigue and unstable coalition dynamics.
Way Forward
- Building Consensus: The Union Government must constitute an Inter-State Council task force to address the apprehensions of regional parties.
- Strengthening the Anti-Defection Law: To prevent mid-term collapses that trigger by-elections, the Tenth Schedule must be made more stringent.
Prelims Value Addition
- Constitutional Articles: Article 83 (Lok Sabha tenure), Article 85 (Dissolution of Lok Sabha), Article 172 (State Assembly tenure).
- Law Commission Report: The 279th Law Commission Report heavily advocated for simultaneous elections.
Mains Value Addition
- Key Quote: “Elections should be a festival of democracy, not a perpetual administrative burden that paralyzes the engine of governance.”

Paper: GS-III (Infrastructure, Energy Security) & GS-II (Tamil Nadu State Policies)
UPSC Relevance: ★★★★★ (Very High)
Why in News?
On September 26, 2026, the Tamil Nadu State Government signed definitive Memorandums of Understanding (MoUs) worth ₹45,000 crore with global energy conglomerates to operationalize Asia’s largest Green Hydrogen and Green Ammonia hub in Thoothukudi.
Understanding Tamil Nadu’s Green Energy Pivot
Tamil Nadu currently leads India in renewable energy installed capacity, heavily relying on wind and solar. However, to decarbonize heavy industries (like cement, steel, and maritime transport), the state is pivoting to Green Hydrogen—produced by splitting water using renewable electricity via electrolysis. Thoothukudi, with its major seaport (V.O. Chidambaranar Port) and vast coastal wind-solar potential, is uniquely positioned to become an export terminal for Green Ammonia to European and East Asian markets.
Key Pillars of the Thoothukudi Hub
| Sector | Key Initiatives & Agreements |
| Desalination Infrastructure | Setting up a 150 MLD (Million Litres Per Day) dedicated desalination plant, ensuring zero extraction from local groundwater sources for electrolysis. |
| Renewable Energy Banking | Tamil Nadu Generation and Distribution Corporation (TANGEDCO) offering flexible “green energy banking” to continuous-process hydrogen plants. |
| Export Logistics | VOC Port upgrading its liquid bulk terminals and cryogenic storage facilities to handle zero-carbon ammonia exports. |
| Manufacturing Ecosystem | Establishing an ancillary SEZ for manufacturing electrolyzers, fuel cells, and specialized storage tanks. |
Strategic Significance
- Decarbonizing State Economy: Aligns with Tamil Nadu’s vision to achieve Net Zero ahead of the national 2070 target, cleaning up the highly industrialized Chennai-Coimbatore-Thoothukudi belt.
- Forex Earnings & FDI: Positions the state as a premier exporter of green molecules, tapping into the European Union’s Carbon Border Adjustment Mechanism (CBAM) compliant markets.
- Employment Generation: The localized manufacturing of electrolyzers is projected to create over 25,000 highly skilled engineering and operational jobs in the southern districts.
Key Challenges in the Sector
- High Levelized Cost: The cost of Green Hydrogen remains around $3.5 to $4 per kg, struggling to compete with grey hydrogen (produced from natural gas) which costs under $1.5 per kg.
- Freshwater Scarcity: Electrolysis is highly water-intensive. Relying on desalination increases the base cost of production and poses marine ecological challenges due to brine discharge.
- Transport and Storage: Liquid hydrogen requires cryogenic cooling at -253°C, making logistics technologically complex and highly explosive.
Way Forward
- Viability Gap Funding (VGF): The State must augment the Central government’s SIGHT (Strategic Interventions for Green Hydrogen Transition) program with localized power-tariff subsidies.
- Mandatory Purchase Obligations: Introduce progressive mandates for state-owned transport corporations and fertilizer plants to procure a minimum percentage of green hydrogen.
Prelims Value Addition
- Green Hydrogen: Produced using renewable energy. (Blue = natural gas + carbon capture; Grey = natural gas without capture).
- VOC Port: One of the 13 major ports in India, located in the Gulf of Mannar.
Mains Value Addition
- Key Quote: “Thoothukudi is no longer just the Pearl City of India; it is rapidly transforming into the Green Energy Capital of the Indo-Pacific.”
Topic 3: India Champions the ‘Global South Debt Relief Pact’ at the 81st UNGA
Paper: GS-II (International Relations, Global Groupings)
UPSC Relevance: ★★★★☆ (High)
Why in News?
On September 25, 2026, India’s External Affairs Minister addressed the 81st session of the United Nations General Assembly (UNGA) in New York. India formally proposed the “Global South Debt Relief and Development Pact,” urging multilateral institutions to restructure sovereign debts crippling African and South Asian nations.
Understanding the Global South Debt Crisis
Post-pandemic economic scarring, combined with aggressive interest rate hikes by the US Federal Reserve and predatory infrastructure lending (often attributed to China’s Belt and Road Initiative), has pushed nearly 40 developing nations into severe debt distress. India is leveraging its geopolitical weight to position itself as the chief negotiator for the Global South, bridging the gap between developing nations and the G7/Bretton Woods institutions.
Key Pillars of India’s UNGA Proposal
| Dimension | Specific Policy Advocacy |
| Debt Restructuring | Demanding the IMF and World Bank expedite the “Common Framework for Debt Treatments” to provide immediate liquidity to defaulting nations. |
| Digital Public Infrastructure (DPI) | Offering India’s open-source DPI suite (identity, payment systems, health registries) completely free of IP costs to developing nations. |
| Climate Finance | Holding developed nations accountable to their unmet $100 billion annual climate finance pledges under the UNFCCC. |
| UNSC Democratization | Pushing for text-based negotiations for expanding the UN Security Council, emphasizing permanent representation for India, Africa, and Latin America. |
Strategic Significance
- Countering Chinese Influence: By advocating for transparent, sustainable financing, India provides an ideological and diplomatic counterweight to Beijing’s opaque bilateral lending practices.
- Diplomatic Capital: Cementing its leadership of the Global South enhances India’s bargaining power with the West on issues like technology transfer and trade tariffs.
Key Challenges
- Institutional Inertia: The US and European nations remain reluctant to dilute their voting shares in the IMF and World Bank.
- Chinese Resistance: China, the world’s largest bilateral creditor, refuses to take “haircuts” (reductions) on its loans, stalling holistic restructuring efforts.
Way Forward
- Minilateral Pressure: India must use forums like the G20, BRICS, and Quad to build overlapping consensus on debt relief.
- South-South Trade: Foster trade settlements in local currencies (like the Rupee-Dirham mechanism) to bypass Dollar dependency.
Prelims Value Addition
- UNGA: The main deliberative, policymaking, and representative organ of the UN.
- Global South: A geopolitical term referring broadly to developing nations in Asia, Africa, and Latin America.
Mains Value Addition

Paper: GS-III (Defence, Security, Indigenization of Technology)
UPSC Relevance: ★★★★★ (Very High)
Why in News?
On September 26, 2026, the Defence Research and Development Organisation (DRDO) successfully test-fired the Long-Range Surface-to-Air Missile (LR-SAM) system under ‘Project Kusha’ off the Odisha coast. The system successfully tracked and destroyed high-speed stealth aerial targets at a range of 250 kilometers.
Understanding Project Kusha
Project Kusha is India’s most ambitious indigenous air defence endeavor, designed to match the capabilities of the Russian S-400 Triumf and the American Patriot systems. It comprises a three-tiered missile architecture capable of intercepting enemy fighter jets, stealth drones, cruise missiles, and precision-guided munitions at ranges of 150 km, 250 km, and 350 km.
Key Pillars of the Air Defence Shield
| Component | Technological Capability |
| Active Electronically Scanned Array (AESA) Radars | Indigenous deep-search radars capable of tracking low-radar-cross-section (stealth) targets from 500 km away. |
| Multi-Tier Interception | Three distinct missile variants to provide overlapping protective bubbles (endo-atmospheric interception). |
| Network Centric Operations | Seamless integration with the Indian Air Force’s IACCS (Integrated Air Command and Control System). |
Strategic Significance
- Two-Front War Preparedness: Vital for neutralizing the combined aerial threats posed by the Chinese PLAAF and the Pakistani Air Force along the LAC and LoC.
- Strategic Autonomy: Reduces India’s dangerous dependency on Russia for the S-400, especially amidst global supply chain disruptions caused by the Ukraine conflict.
- Export Potential: Makes India a premium exporter of strategic defense systems to friendly nations in Southeast Asia (like the BrahMos export to the Philippines).
Key Challenges

Topic 5: Tamil Nadu Assembly Passes Resolution Against Centralized Delimitation
Paper: GS-II (Polity, Centre-State Relations, Federalism)
UPSC Relevance: ★★★★★ (Very High)
Why in News?
On September 25, 2026, the Tamil Nadu Legislative Assembly unanimously passed a resolution urging the Union Government to decouple the upcoming 2026 Delimitation exercise from population metrics. This is in response to growing anxieties that Southern states will lose their proportional political representation in the Lok Sabha.
Understanding the Delimitation Crisis
Delimitation is the act of redrawing boundaries of Lok Sabha and State Assembly seats to represent changes in population. Under the 84th Amendment, the delimitation of constituencies was frozen until the first census post-2026. Southern states like Tamil Nadu and Kerala successfully implemented the Centre’s family planning programs, dropping their Total Fertility Rate (TFR) below replacement levels. Conversely, Northern states experienced population booms. If seats are reapportioned purely by current population, Southern states will be heavily penalized for their socio-economic success by losing seats in Parliament.
Key Pillars of the State’s Argument
| Dimension | Core Argument Raised |
| The “Penalty for Progress” | States that successfully controlled population growth and improved human development indices should not suffer political marginalization. |
| Financial Devolution | A drop in political weight directly impacts bargaining power in the Finance Commission regarding the allocation of central tax revenues. |
| Federal Balance | Purely demographic delimitation violates the quasi-federal structure by shifting absolute legislative hegemony to the Hindi heartland. |
Strategic Significance
- Protecting Cooperative Federalism: The issue cuts to the core of India’s unity. Disenfranchising the economic engine states of the South could trigger severe sub-nationalist friction.
- Redefining Representation: Prompts a national debate on whether “One Person, One Vote” must be balanced against state-level structural equality (akin to the US Senate model).
Key Challenges
- Constitutional Mandate: Article 81 currently mandates that the ratio of population to Lok Sabha seats must be broadly uniform across all states, legally complicating any deviation.
- Democratic Deficit in the North: Ignoring current population data means a single MP in Uttar Pradesh represents vastly more citizens than an MP in Tamil Nadu, creating an unequal democratic mandate.
Way Forward
- Increase Total Lok Sabha Seats: Expand the total capacity of the Lok Sabha (the new Parliament building accommodates 888 MPs) so that Northern states gain seats without Southern states losing any.
- Redefine Rajya Sabha Powers: Empower the Rajya Sabha as a true council of states with equal representation for all states regardless of population, safeguarding regional interests.
Prelims Value Addition
- Article 82: Readjustment of allocation of seats in the House of the People after each census.
- Delimitation Commission: Appointed by the President; its orders have the force of law and cannot be challenged in any court.
Mains Value Addition
- Key Quote: “Federalism cannot survive if the states that built the nation’s human capital are structurally subordinated in the halls of Parliament.”
Topic 6: RBI Launches Offline Framework for Retail Digital Rupee (e₹-R)
Paper: GS-III (Indian Economy, Digitalization, Banking)
UPSC Relevance: ★★★★☆ (High)
Why in News?
On September 26, 2026, the Reserve Bank of India (RBI) officially launched the offline transaction framework for the Retail Central Bank Digital Currency (e₹-R). This marks the final phase of the digital rupee pilot, enabling users to transfer digital currency without internet connectivity using near-field communication (NFC) and Bluetooth.
Understanding the Offline CBDC
A major limitation of UPI (Unified Payments Interface) is its absolute reliance on telecom networks and banking servers. The offline e₹-R solves this by acting as true “digital cash.” Tokens are stored securely on the hardware wallet of a smartphone. During an offline transaction, tokens leap directly from the payer’s device to the payee’s device in real-time, functioning exactly like handing over physical banknotes in a remote village with zero network coverage.
Key Pillars of the Framework
| Feature | Functionality |
| NFC Integration | Uses proximity communication to transfer cryptographic tokens instantaneously. |
| Risk Limits | To prevent double-spending and fraud, offline transactions are capped at ₹500 per transaction, with a total wallet limit of ₹5,000 until synced online. |
| Anonymity | Small-value offline transactions leave no trail on the central ledger, mimicking the privacy of physical cash. |
| Interoperability | The e₹-R wallets are now fully interoperable with existing UPI QR codes for seamless merchant adoption. |
Strategic Significance
- Deep Financial Inclusion: Solves the connectivity hurdle in rural, hilly, and tribal regions, bringing the unbanked into the digital economy.
- Disaster Resilience: Ensures the payment system remains functional during natural disasters, floods, or internet shutdowns.
- Reducing Cash Dependency: Cuts down the massive logistical costs borne by the RBI in printing, transporting, and managing physical currency notes.
Key Challenges
- Security Vulnerabilities: Hardware wallets can be compromised if a device is stolen, and sophisticated bad actors might attempt cryptographic “double-spending” before the device syncs to the network.
- Hardware Limitations: Requires smartphones with NFC capabilities, which are less prevalent in the budget smartphone segment used by lower-income demographics.
Way Forward
- Smart Card Rollout: The RBI should introduce offline e₹ functionality in physical smart cards (like Metro cards) for users who do not own smartphones.
- Public Awareness Campaigns: Educate the masses on the difference between UPI (bank-money) and CBDC (central bank sovereign money) to drive adoption.
Prelims Value Addition
- CBDC: A legal tender issued by a central bank in digital form. It is the same as fiat currency and is exchangeable one-to-one with fiat currency.
- Double Spending: The risk that a digital currency can be spent twice.
Mains Value Addition
- Key Quote: “The offline digital rupee bridges the ultimate gap in India’s digital public infrastructure, ensuring that the last mile is never left behind due to a dropped signal.”
Topic 7: India Ratifies the Global Plastics Treaty in Nairobi
Paper: GS-III (Environment, Conservation, Pollution)
UPSC Relevance: ★★★★☆ (High)
Why in News?
On September 26, 2026, at the concluding session of the Intergovernmental Negotiating Committee (INC) in Nairobi, India officially ratified the Global Plastics Treaty, a legally binding UN instrument to end plastic pollution, particularly in the marine environment.
Understanding the Treaty
Initiated by the UN Environment Assembly (UNEA), this treaty marks the most significant environmental multilateral pact since the Paris Agreement. It covers the full lifecycle of plastics—from the extraction of fossil fuels for polymers to design, production, and end-of-life disposal. India, which generates roughly 3.5 million tonnes of plastic waste annually, played a crucial role in negotiating terms that balance environmental mandates with the economic realities of developing nations.
Key Pillars of India’s Commitments
| Policy Mandate | Actionable Framework |
| Phasing Out Primary Polymers | Gradual reduction in the production of virgin single-use plastics by 2030, capping fossil-fuel subsidies for petrochemical plants. |
| Extended Producer Responsibility (EPR) | Making FMCG brands financially and legally responsible for retrieving and recycling 100% of their plastic packaging. |
| Just Transition | Formally recognizing and integrating informal waste-pickers (Safai Sathis) into the formalized circular economy. |
| Microplastics Regulation | Phasing out intentionally added microplastics in cosmetics, textiles, and agricultural products. |
Strategic Significance
- Marine Ecosystem Restoration: India’s coastline is highly vulnerable to marine litter. The treaty forces regional cooperation to clean the Bay of Bengal and the Arabian Sea.
- Boost to Circular Economy: Forces rapid innovation in alternative biodegradable materials (e.g., seaweed packaging, corn-starch plastics), creating a massive green-tech market.
Key Challenges
- Economic Impact on MSMEs: Thousands of MSMEs rely on manufacturing cheap single-use plastics. An abrupt ban threatens livelihoods without adequate transition financing.
- Enforcement Deficit: While India banned single-use plastics domestically in 2022, enforcement on the ground remains notoriously weak due to municipal apathy.
- Lack of Alternatives: Biodegradable alternatives currently cost 3-4 times more than conventional plastics, driving up costs for end-consumers.
Way Forward
- Global Plastics Fund: India must pressure developed nations to operationalize a dedicated fund for technology transfer regarding advanced chemical recycling.
- Empower Local Bodies: Municipal corporations must be heavily funded to set up Material Recovery Facilities (MRFs) to segregate waste at the source.
Prelims Value Addition
- UNEA: The UN Environment Assembly is the world’s highest-level decision-making body on the environment.
- EPR: A policy approach under which producers are given a significant responsibility for the treatment or disposal of post-consumer products.
Mains Value Addition
- Key Quote: “We cannot recycle our way out of the plastic crisis; we must turn off the tap at the source of production.”
Topic 8: ISRO Successfully Recovers Gaganyaan’s Final Uncrewed Module (G2)
Paper: GS-III (Science & Technology, Space Exploration)
UPSC Relevance: ★★★★★ (Very High)
Why in News?
On September 25, 2026, the Indian Space Research Organisation (ISRO) successfully completed the ‘G2’ mission—the second and final uncrewed orbital test flight of the Gaganyaan program. The Crew Module safely splashed down in the Bay of Bengal and was recovered by the Indian Navy, clearing the final hurdle for India’s historic crewed spaceflight slated for early 2027.
Understanding the G2 Mission
The G2 mission was designed to rigorously validate the human-rating of the LVM3 launch vehicle and the life-support systems of the orbital module. Unlike G1, this flight carried “Vyommitra,” ISRO’s humanoid robot, equipped with advanced telemetry sensors to simulate human physiological responses to microgravity and the intense G-forces of atmospheric re-entry.
Key Pillars of the Mission Test
| Sub-System Tested | Technological Milestone Achieved |
| Environmental Control & Life Support (ECLSS) | Maintained a flawless 1-bar atmospheric pressure, 25°C temperature, and managed carbon dioxide scrubbing for 3 days in orbit. |
| Thermal Protection System (TPS) | The heat shield successfully withstood temperatures exceeding 2000°C during the fiery re-entry phase into Earth’s atmosphere. |
| Parachute Deployment | Flawless sequential deployment of apex, drogue, and main parachutes, slowing the capsule from hypersonic speeds to a safe 8.5 m/s splashdown. |
| Naval Recovery Operations | Indian Navy’s MARCOS deployed via helicopters to secure the capsule within 30 minutes of splashdown, testing real-world rescue logistics. |
Strategic Significance
- Elite Club: Successful human spaceflight will make India only the fourth nation (after the US, Russia, and China) to independently send humans to space.
- Precursor to BASS: This tech demonstration is the foundational building block for establishing the Bharatiya Antariksha Station (Indian Space Station) by 2035.
- Deep Space Confidence: Proving crewed capabilities ensures India can participate as an equal partner in future international lunar missions (like the Artemis Accords).
Key Challenges
- Zero Margin for Error: Unlike satellite launches, human spaceflight requires a reliability rating of 99.99%. Any failure in the upcoming crewed mission would be catastrophic.
- Space Debris (Kessler Syndrome): Low Earth Orbit (LEO) is highly congested. Navigating the crew module safely through orbital debris requires highly advanced space situational awareness.
Way Forward
- Crew Training: Finalize the micro-gravity simulator training for the selected Indian Air Force test pilots (Gaganauts).
- Private Sector Scaling: ISRO must begin transferring the manufacturing of non-critical LVM3 components to private space startups (like Skyroot/Agnikul) to free up internal resources for deep-space R&D.
Prelims Value Addition
- Vyommitra: Half-humanoid robot developed by ISRO to simulate human functions in space.
- LVM3: Launch Vehicle Mark 3 (formerly GSLV Mk III), ISRO’s heaviest launch vehicle, human-rated for the Gaganyaan mission.
Mains Value Addition
- Key Quote: “The successful splashdown of G2 is not just a scientific achievement; it is the final rehearsal before Indian footprints leave the bounds of Earth on an indigenous spacecraft.”
