GS Paper 2: Polity, Governance, Social Justice & IR

UPSC's GS Paper 2 questions since 2016 → GS Paper 2 syllabus →

Cauvery Allocation: Karnataka Invokes 'Changed Circumstances'

Why in news: Replying to Tamil Nadu in the SC, Karnataka said it may seek to reopen the Cauvery allocation on grounds of 'inequitable allocation' and 'changed circumstances', citing India's stand on the Indus Waters Treaty.

For Mains: Use in GS2 (federalism, inter-State relations) to show why tribunal awards rarely end disputes — rainfall variability and growing demand keep reopening 'final' allocations; argue for distress-sharing formulas and basin-level bodies.

India's Stakes in the WHO Pandemic Agreement

Why in news: At the UN High-Level Meeting on pandemic preparedness (September 2026), India backed the WHO Pandemic Agreement while stressing national sovereignty and equitable access to vaccines and drugs.

For Mains: Use in GS2 (international institutions, health) to discuss global health equity, vaccine nationalism during COVID-19 and India's role as a voice of the Global South.

FCRA Registration and Religious Conversion: Madras HC Ruling

Why in news: The Madras HC (Madurai Bench) held that organisations engaged in religious conversion can be denied FCRA registration, upholding the rejection of a Kodaikanal trust's application.

For Mains: Use in GS2 (role of NGOs, Article 25) to weigh the freedom to propagate religion against the State's power to regulate foreign funding for security and social harmony.

Mercy Petitions and Delay: The Rajoana Case

Why in news: The Centre opposed death-row convict Balwant Singh Rajoana's plea to commute his sentence over the delay in deciding his mercy petition, pending with the President since 2012; the SC will hear it on merits on October 28.

For Mains: Use in GS2 (executive powers, Article 21) to discuss how executive delay converts a legal sentence into prolonged mental torture, and why time-bound disposal of mercy petitions is needed.

NCSC Pushes Banks to Report the SC Share in Schemes

Why in news: On the NCSC's prompting, the Finance Ministry directed State- and UT-level bankers' committees to report the share of SC beneficiaries in flagship schemes, scheme-wise and bank-wise, by October 9.

For Mains: Use in GS2 (welfare of vulnerable sections, financial inclusion) to argue that inclusion in credit must be measured, not assumed — disaggregated, published data is the first step to accountability.

GS Paper 3: Economy, Environment, S&T & Energy

UPSC's GS Paper 3 questions since 2016 → GS Paper 3 syllabus →

RBI Raises the Repo Rate to 5.5%, Shifts to 'Calibrated Tightening'

Why in news: The MPC raised the repo rate by 25 basis points to 5.5% and changed its stance from neutral to calibrated tightening, signalling that rate cuts are off the table.

For Mains: Use in GS3 (monetary policy, inflation) to explain the limits of rate hikes against supply shocks — fuel and food prices need fiscal and supply-side action alongside RBI's move.

Cement: The Hard-to-Abate Sector and Net Zero

Why in news: Cement accounts for 7–11% of global emissions, and India's rising construction demand makes the sector central to its 2070 net-zero goal.

For Mains: Use in GS3 (climate change, industry) to explain 'hard-to-abate' sectors and why net zero needs material efficiency and CCUS, not just renewable power.

From the Brink to a Comeback: Species Recovery in India

Why in news: During Wildlife Week (October 2–8), new data show recoveries in lions, vultures, tahr and dugongs, as India prepares a National Red List of its species.

For Mains: Use in GS3 (conservation) to show that species recovery is possible but slow — it needs science, communities and multi-year funding, not one-off projects.

Chemistry Nobel 2026: Mirror-Image Molecules

Why in news: French chemist Henri Kagan and Japanese chemist Kenso Soai won the 2026 Nobel Prize in Chemistry for showing how small imbalances in chiral molecules can be amplified in chemical reactions.

For Mains: Use in GS3 (S&T, pharmaceuticals) to show how basic chemistry shapes drug safety and cost — and why India's pharma industry needs strong research in asymmetric synthesis.

UCIL Plans to Double Uranium Output

Why in news: Uranium Corporation of India Ltd. plans to double domestic uranium output by 2036 through four greenfield projects and by recovering uranium from copper-mine residue.

For Mains: Use in GS3 (energy security) to show how domestic fuel supply, circular-economy mining and private participation fit into India's nuclear expansion.

GS Paper 4: Ethics

UPSC's GS Paper 4 questions since 2016 → GS Paper 4 syllabus →

'Students, Not Antisocial Elements': Restoring Trust in Recruitment

Why in news: The Bombay HC said students protesting alleged malpractices in MPSC recruitment are not antisocial elements and asked the Maharashtra government to restore their trust.

For Mains: Use in GS4 (probity, trust in institutions, empathy) and GS2 (constitutional bodies) to show that transparent, time-bound recruitment is itself a public service.
