GS Paper 1: Indian Geography & Climatology

UPSC's GS Paper 1 questions since 2016 →

A Tale of Two Monsoons: Maharashtra Declares Drought in 265 Taluks as U.P. Battles Record Floods

Why in news: Maharashtra declared drought in 265 of its 358 taluks after a prolonged rainfall deficit, even as a depression over north- east Madhya Pradesh dumped record rain on Uttar Pradesh, killing six and flooding 63 districts.

For Mains: Use this as a live GS1 example of how a single monsoon trough/depression can simultaneously produce drought in one region and flooding in another, and link it to GS3 disaster-management frameworks (State Disaster Response Fund triggers, drought manuals).

GS Paper 2: Polity, Governance & Social Justice

UPSC's GS Paper 2 questions since 2016 →

EC Goes Into Damage-Control Mode: Special Enrolment Drive, Extended Deadlines Amid SIR Row

Why in news: Facing sustained criticism over the Special Intensive Revision (SIR) and reports of internal dissent, the Election Commission announced a special enrolment drive and extended claims-and-objections deadlines, while a fresh explainer clarified exactly how a Chief Election Commissioner can be removed.

For Mains: A ready-made answer for GS2 questions on the independence and collegial functioning of constitutional bodies, using the Anoop Baranwal and T.N. Seshan judgments to discuss checks on unilateral authority.

Delhi HC: A Muslim Personal-Law Marriage Cannot Shield an Accused From the POCSO Act

Why in news: The Delhi High Court held that a marriage recognised under Muslim personal law cannot confer immunity from prosecution under the POCSO Act when the wife was below 18 at the time of sexual intercourse, dismissing a plea to quash an FIR.

For Mains: Use this to discuss the relationship between personal laws and secular criminal law, the constitutional basis for a uniform age of consent, and the child-protection rationale behind POCSO overriding customary/religious marriage practices.

Andhra Pradesh Refuses to Defend Centre's Transgender Rights Law Amendments in Supreme Court

Why in news: The NDA-ruled Andhra Pradesh government told the Supreme Court it has no role in defending the Centre's 2026 amendments to the Transgender Persons (Protection of Rights) Act, even as Uttarakhand separately defended the changes.

For Mains: Frame this around federalism in rights-implementation (a State declining to defend a central law it administers), and the tension between self-determination and physiological-criteria approaches to gender-identity law.

At Least 27 UPSC CSE Prelims Questions Challenged as 'Ambiguous' Before the Central Administrative Tribunal

Why in news: Civil Services Examination aspirants have challenged at least 27 questions across General Studies and CSAT papers in this year's Prelims, arguing the provisional answer key contains incorrect, unsupported, or multiple-correct-answer options.

For Mains: Relevant for GS2 answers on transparency and accountability in public examination bodies, and the administrative-law principle that a statutory examining body's discretion is still subject to judicial review for patent error.

GS Paper 3: Environment, Infrastructure & Disaster Management

UPSC's GS Paper 3 questions since 2016 →

Karnataka Legislature Unanimously Rejects Kasturirangan-Based Western Ghats ESA Draft, Seeks a Year for Physical Survey

Why in news: Both Houses of the Karnataka Legislature unanimously rejected the seventh draft notification declaring parts of the Western Ghats an Ecologically Sensitive Area, demanding a year to conduct a physical, village-by-village survey before any area is finalised.

For Mains: Contrast the precautionary, biodiversity-first Gadgil approach with Kasturirangan's development- accommodating compromise, and discuss cooperative federalism when a shared ecological unit spans States with divergent stances.

Vedanta Seeks to Reopen Niyamgiri Bauxite Mine, 13 Years After Gram Sabhas Rejected It

Why in news: Vedanta Group chairman Anil Agarwal asked Odisha to reopen the Niyamgiri bauxite reserves for mining, nearly 13 years after Gram Sabhas of the Dongria Kondh – a Particularly Vulnerable Tribal Group – rejected the project in India's first environmental referendum.

For Mains: Use this to weigh mineral resource development and Atmanirbhar Bharat goals in aluminium/critical minerals against Gram Sabha consent rights under the Forest Rights Act and PESA, 1996 – a recurring GS2/GS3 tribal-rights theme.

Centre Notifies Kandla, JNPA, Mundra and Paradip as India's First 'Mega Ports'

Why in news: The Union government notified Deendayal (Kandla), Jawaharlal Nehru, Mundra and Paradip as 'mega ports' under the new Indian Ports Act, 2025, a fresh classification meant to channel priority infrastructure investment to India's highest-throughput gateways.

For Mains: Link this to India's Sagarmala programme, port-led development strategy, and the shift from a Centre- State 'major/minor port' binary to a throughput-based mega-port classification under the new 2025 Act.

IIT-Madras Tool Flags That Standard Seismic Maps Misjudge Risk for Himalayan 'Megadams'

Why in news: An IIT-Madras team evaluated 6,545 dams under India's National Dam Safety Authority and found that standard seismic zone maps both under- and over-estimate earthquake risk for large Himalayan dams like Tehri and Bhakra, once site-specific modelling is applied.

For Mains: Use this for a GS3 disaster-management/S&T answer on strengthening critical infrastructure resilience, contrasting broad seismic zonation with site-specific probabilistic hazard modelling for large dams.

GS Paper 4: Ethics, Integrity & Aptitude

UPSC's GS Paper 4 questions since 2016 →

Haryana's Tele-ECG Push: An ASHA Worker and a Rural Doctor's Three-Minute Diagnosis That Saved a Life

Why in news: A Haryana government-Sunfox Technologies tele-ECG partnership let a rural medical officer diagnose ASHA worker Raj Rani's blocked coronary artery in under three minutes at a Community Health Centre, stabilising her before a life-saving angioplasty – a model of proactive public service in a State with rural India's biggest cardiac-care gap.

For Mains: Use this as a positive exemplar of empathy and dedication to public service in last-mile healthcare delivery – a GS4 answer can cite it alongside a GS2 point on strengthening India's primary healthcare infrastructure.
