Prelims General Studies Paper I

The Zojila Tunnel project recently achieved a major breakthrough at Minamarg in Kargil district, bringing India closer to year-round road connectivity between Jammu & Kashmir and Ladakh. The tunnel is significant for UPSC because it connects infrastructure development, Himalayan geology, disaster risk, border-road strategy, tourism, regional integration and engineering methods used in fragile mountain terrain.

The question of whether a political party can use a “cockroach” as its election symbol came into focus after reports around the Cockroach Janta Party and India’s election-symbol rules. The issue is important for UPSC because it explains the Election Commission of India’s powers, the Election Symbols Order, reserved and free symbols, registered unrecognised parties and the role of symbols in India’s electoral democracy.

Pfizer has reported mid-stage clinical-trial results for berobenatide, an investigational GLP-1 receptor agonist being studied as a possible once-monthly obesity injection. The development is important for UPSC because it connects biotechnology, chronic disease management, clinical-trial regulation, public health policy, India’s rising obesity burden and ethical questions around access to expensive weight-loss medicines.

India's two flagship decentralised solar schemes — PM Surya Ghar: Muft Bijli Yojana (rooftop solar for households) and PM-KUSUM (solar power for farmers) — are running well below their targets, a gap recently flagged by the Parliamentary Estimates Committee. A key reason is the paradox of free and subsidised power offered by several states, which removes the incentive to install rooftop solar. This article explains both schemes in detail, the latest progress figures and the sharp inter-state disparity, the power-subsidy paradox, and why decentralised solar is central to India's clean energy transition and 500 GW non-fossil target by 2030.

The Stockholm International Peace Research Institute (SIPRI) has released its Yearbook 2026, estimating that India's nuclear stockpile has grown to about 190 warheads as of January 2026 (up from 180 a year earlier), moving slightly ahead of Pakistan's estimated 170. SIPRI also assessed that India may have begun deploying a small number of warheads on a nuclear-armed submarine conducting deterrence patrols, hinting at a shift in its long-standing peacetime posture. This article explains the report's key findings, India's nuclear doctrine of credible minimum deterrence and No First Use, the structure of India's nuclear triad and second-strike capability, its command-and-control system, and India's position on global non-proliferation treaties.

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.

The Union government is preparing to reintroduce its constitutional amendment for delimitation and women's reservation, two months after the Constitution (131st Amendment) Bill, 2026 was defeated in the Lok Sabha in April for want of a two-thirds majority. The reworked plan reportedly seeks to add clarity that every state's existing seat share will be protected even as the House is expanded to around 850 seats, with allocation among states kept proportionate to the 1971 Census — a move aimed at winning over southern states and the DMK. This article explains what delimitation is, the constitutional provisions (Articles 81, 82, 170, 330, 332), the 1971 Census "freeze", the women's reservation link, the North-South federalism debate, and why a Constitution Amendment Bill can fail despite a clear majority.

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.

The first comprehensive Delhi Bird Atlas, released on 5 June 2026, ranks Delhi as the world's second-richest national capital for bird diversity after Nairobi, with 471 species on the city's bird list. Prepared by the Delhi Forest Department with Bird Count India as a citizen-science project, it maps the distribution and abundance of birds using a grid-based method and links Delhi's richness to the Aravalli Ridge, the Yamuna and Sahibi floodplains, and the Central Asian Flyway. This article explains what a bird atlas is, the Central Asian Flyway and global flyways, the species of conservation concern recorded, the citizen-science and eBird method, and India's framework for protecting migratory birds and wetlands — all mapped to the UPSC syllabus.

A wildlife trail in the Bhondsi stretch of the Aravallis near Gurugram, Haryana, has led researchers to a cluster of prehistoric petroglyphs, cupules and Stone Age tools, now being documented by the ASI and the state archaeology department. The find is in the news for showing a rare "chronological continuity" of human activity in the Aravallis and for the threat it faces from the land mafia. This article explains what petroglyphs and cupules are, the Palaeolithic-to-Mesolithic chronology, the Acheulean tool tradition, comparisons with Bhimbetka and other rock-art sites, and the legal framework for protecting India's heritage — 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.
