Mains General Studies Paper II

The Great Nicobar Island Development Project has returned to the spotlight after government sources defended the roughly Rs 81,000-crore plan as a strategically vital national initiative, rejecting the charge that it is "one of the biggest scams" and a crime against the island's natural and tribal heritage. The sources clarified that the existing INS Baaz runway will not be extended to the planned 10,000 feet because of the ecological and tribal costs, and argued that India's wider maritime needs cannot be met by expanding defence assets alone. This article explains the project's components, the strategic geography of Great Nicobar, the logic of a transshipment port at Galathea Bay, and the environmental and tribal-rights concerns at the heart of the ecology-versus-security debate.

India is reworking the template for its Bilateral Investment Treaties (BITs) to make them more investor-friendly while protecting its sovereign policy space, after years of falling net foreign investment and costly arbitration defeats. Reports indicate the Centre is anchoring the new model on three principles: a minimum two-year window for exhausting local remedies before international arbitration, no Most-Favoured Nation (MFN) clause, and exclusion of tax matters. This article explains what BITs are, how India's treaty regime evolved from 1994 to the restrictive 2016 Model BIT, the arbitration losses (White Industries, Vodafone, Cairn, Devas) that reshaped policy, the working of Investor-State Dispute Settlement (ISDS), and what the proposed changes mean for India's FDI strategy and regulatory autonomy.

The Supreme Court, in Prajwala v. Union of India (May 2026), has framed a binding "Victim Protection Plan" for survivors of trafficking for commercial sexual exploitation (CSE), holding that they have a fundamental right to rehabilitation and must never be treated as criminals. Invoking Articles 21, 23, 32 and 142, the Court placed victims' consent and dignity at the centre and distinguished voluntary adult sex workers, for whom forcible "rescue" does not arise. The plan will operate until Parliament enacts a comprehensive anti-trafficking law. This article explains the judgment, the Prajwala case, the Immoral Traffic (Prevention) Act, and the constitutional and international framework on trafficking — mapped to the UPSC syllabus.

With the Strait of Hormuz effectively closed and contested amid the 2026 Iran war, energy tankers are increasingly "going dark" — switching off their AIS transponders to cross the chokepoint undetected. Once a tactic of the sanctioned-oil "shadow fleet", dark transits now make up the majority of crossings, raising collision and enforcement risks. This article explains the geography and importance of the Strait of Hormuz, how AIS and the dark/shadow fleet work, the conflict context, India's heavy dependence on the strait for oil, LNG and LPG, India's energy-security response, and the wider issue of maritime chokepoints — all mapped to the UPSC syllabus.

AI authorship is back in the spotlight after the 2026 Commonwealth Short Story Prize was hit by allegations that some winning entries were AI-generated, with an AI detector flagging one Caribbean-winning story as "100% AI". The episode has revived a hard question: can software reliably tell whether a text was written by a human or a machine? This article explains the machine-learning science behind such detectors, the "AI tells" they look for, why the tools are not foolproof (false positives, low-entropy text, code and short text), and what this means for education, writing and publishing — all mapped to the UPSC syllabus.

The newly released National Family Health Survey (NFHS-6), 2023-24 shows that infant and young child feeding practices in Delhi have declined sharply across almost every indicator compared with NFHS-5 (2019-21). Early initiation of breastfeeding, exclusive breastfeeding and the share of children getting an adequate diet have all fallen, and underweight has risen — even as several national child-nutrition indicators improved. This article explains what NFHS-6 is, the key breastfeeding and complementary-feeding indicators, what stunting, wasting and underweight mean, India's nutrition schemes and legal framework, and the way forward — all mapped to the UPSC Prelims and Mains syllabus.

The Reserve Bank of India's Annual Report for 2025-26 has flagged the risk of "elevated" sovereign bond yields and a possible reversal of the global monetary-easing cycle, while the Chief Economic Advisor has called the end of near-zero interest rates and quantitative easing the single most consequential shift in global capital markets. With foreign portfolio investors pulling out record sums and the India-US yield gap shrinking, this article explains government bonds, bond yields, quantitative easing, negative interest rates, push-versus-pull capital flows, and what the drying up of cheap global money means for India's markets, rupee and growth.

The Ministry of Health and Family Welfare released the National Family Health Survey-6 (NFHS-6, 2023-24) factsheets on 29 May 2026, and the number of indicators has fallen from 131 in NFHS-5 to 101 — with data on anaemia prevalence, sex ratio at birth, infant and child mortality, cancer screening, HIV awareness, clean cooking fuel and sanitation no longer reported. The government calls it "data harmonisation"; critics call it suppression. This article explains what NFHS is, why these indicators were dropped, the meaning of data harmonisation, the role of the Sample Registration System and ICMR, and the survey's key health findings on fertility, obesity and immunisation for the UPSC GS-II Governance and Health syllabus.

India and Australia held the 2nd India-Australia Defence Ministers' Dialogue in New Delhi on 1 June 2026, advancing maritime domain awareness, defence co-production and Indo-Pacific security cooperation.

UN-Habitat has released the World Cities Report 2026, "The Global Housing Crisis: Pathways to Action", at the 13th World Urban Forum (WUF13) in Baku, Azerbaijan, warning that 3.4 billion people now lack adequate housing and that financialisation is a key driver of unaffordability. This article explains the report's findings, the meaning and measurement of housing affordability, the concept of financialisation, India's specific data, the constitutional right to shelter, and schemes like PMAY.

The Central Board of Secondary Education (CBSE) is facing nationwide criticism after rolling out On-Screen Marking (OSM) — a fully digital answer-sheet evaluation system — for Class 12 board exams for the first time in 2026, amid complaints of low marks, blurred scans, and a crashing re-evaluation portal. This article explains what OSM is, how digital evaluation works, why CBSE adopted it, what went wrong in the rollout, the constitutional and governance questions it raises, and the wider e-governance lessons for India's examination system.

The Supreme Court has invoked its extraordinary powers under Article 142 to crack down on rampant illegal sand mining inside the tri-state National Chambal Gharial Sanctuary, pulling up Rajasthan, Madhya Pradesh and Uttar Pradesh for "casual and indolent" inaction after two forest guards were killed in 2026. This in-depth explainer covers the Chambal sanctuary's unique ecology, the critically endangered gharial, India's sand-mining laws (MMDR Act, Sustainable Sand Mining Guidelines), the Deepak Kumar verdict, denotification controversies, and the constitutional principles of environmental governance — everything a UPSC aspirant needs in one place. Why in News The Supreme Court of India is hearing a suo motu case on large-scale illegal sand mining inside and around the National Chambal (Gharial) Sanctuary, a riverine protected area shared by Rajasthan, Madhya Pradesh and Uttar Pradesh. In a series of strongly worded orders through April and May 2026, the Court has rebuked the three state governments for administrative apathy, linked their inaction to the killing of frontline forest staff, and invoked Article 142 of the Constitution to issue sweeping enforcement directions. The case has brought national attention to sand mining as an environmental and rule-of-law crisis, and to the survival of the critically endangered gharial, whose last major wild stronghold is the Chambal.
