GK One-Liners

What: The National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI) released India’s first-ever monthly bulletin under the Periodic Labour Force Survey (PLFS) for April 2025. Key metrics under the Current Weekly Status (CWS) methodology: Unemployment Rate (UR) — 5.1%; Labour Force Participation Rate (LFPR) — 55.6%; Worker Population Ratio (WPR) — 52.8%. This marks a significant shift from the earlier annual and quarterly PLFS reporting cadence, with monthly reporting effective from January 2025.

How: The PLFS, launched in 2017, is the primary instrument for measuring employment and unemployment in India. The CWS methodology classifies a person’s activity status based on their participation in the labour market during any day in the reference week — making it more sensitive to short-term labour market fluctuations than the Usual Principal Status (UPS) measure used in annual reports. Monthly data allows near-real-time tracking of employment trends, useful for policy calibration and economic monitoring.

Why: PLFS, LFPR, WPR, and unemployment data are high-frequency topics in UPSC Prelims (GS-III — Economy) and Banking Awareness. Key facts: PLFS launched — 2017; nodal body — NSO/MoSPI; April 2025 UR — 5.1%; LFPR — 55.6%; WPR — 52.8%; CWS methodology; monthly reporting from January 2025. The distinction between CWS and UPS methodologies is a nuanced Mains GS-III anchor. This shift to monthly reporting is a policy milestone worth noting for current affairs questions.

What: Bharat Electronics Limited (BEL) signed a contract with the Indian Army for the manufacture of IDDIS — the Integrated Drone Detection and Interdiction System — co-developed with the Defence Research and Development Organisation (DRDO). The system is designed to detect drones at a range of 5–8 kilometres and neutralise them using laser-based and jamming technologies. The contract also resulted in BEL securing ₹572 crore in additional orders. IDDIS is designed to complement the Akashteer system, India’s automated air defence control and reporting framework.

How: IDDIS functions as a counter-Unmanned Aerial Vehicle (counter-UAV or C-UAV) system. Detection is achieved through radar, Radio Frequency (RF) sensors, and electro-optical cameras, while interdiction is carried out via directed-energy laser weapons and RF jamming to disable or destroy hostile drones. Its integration with Akashteer — which provides automated, networked situational awareness for low-level airspace — creates a layered, automated anti-drone defence architecture for the Indian Army.

Why: Anti-drone technologies and India’s indigenisation push are recurring themes in UPSC Prelims (Defence, Science & Technology) and CDS exams. Key anchors: IDDIS co-developed by BEL + DRDO; detection range 5–8 km; methods — laser and jamming; complements Akashteer; BEL order value — ₹572 crore. The broader context of drone warfare (as seen in Ukraine, West Asia) making C-UAV systems strategically critical is a strong Mains GS-III and GS-II essay thread.

What: Union Minister Ashwini Vaishnaw inaugurated Renesas Electronics India’s 3-nanometre (3nm) chip design centres in Noida (Uttar Pradesh) and Bengaluru (Karnataka) — making India’s first-ever chip design facilities operating at the 3nm process node. Previously, India’s semiconductor design ecosystem worked at the 7nm and 5nm nodes. Renesas Electronics is a Japanese semiconductor company. The centres are backed by the Chips to Startup (C2S) and Design Linked Incentive (DLI) schemes under the India Semiconductor Mission (ISM) 2.0.

How: A chip’s process node (measured in nanometres) indicates transistor density — smaller nodes mean more transistors per chip, yielding higher performance and energy efficiency. Moving from 5nm to 3nm represents a significant leap, enabling design of more powerful processors, AI accelerators, and communication chips. The C2S scheme supports academic and startup-level chip design talent, while the DLI scheme provides financial incentives to domestic chip designers — together forming the demand-side ecosystem for India’s semiconductor ambitions.

Why: India’s semiconductor ecosystem — design, fabrication, and packaging — is a top UPSC GS-III (Science & Technology, Economy) topic. Key facts: first 3nm chip design in India; company — Renesas Electronics (Japan); locations — Noida and Bengaluru; schemes — C2S (Chips to Startup) and DLI (Design Linked Incentive) under ISM 2.0; ministry — MeitY. The progression from 7nm → 5nm → 3nm is a useful timeline for answering questions on India’s semiconductor capability advancement.

What: President Droupadi Murmu presented the 58th Jnanpith Award on May 16, 2025 at Vigyan Bhawan, New Delhi, to Jagadguru Ramabhadracharya for his contributions to Sanskrit literature and to Gulzar (born Sampooran Singh Kalra) for his contributions to Urdu literature. The Jnanpith Award is India’s highest literary honour, instituted in 1965 by the Bharatiya Jnanpith organisation. It carries a cash prize of ₹11 lakh and a Vagdevi (Saraswati) statue. Gulzar is also a celebrated Hindi film lyricist, screenwriter, and director.

How: The Jnanpith Award is conferred annually on an Indian citizen for outstanding contributions to Indian literature in any of the languages listed in the 8th Schedule of the Constitution of India plus English. It is selected by the Bharatiya Jnanpith Selection Board. Jagadguru Ramabhadracharya is a notable Sanskrit scholar, Vaishnava philosopher, and founder of Tulsi Peeth in Chitrakoot, Uttar Pradesh. Gulzar has previously won the Academy Award (Oscar) for the song ‘Jai Ho’ from Slumdog Millionaire and the Dadasaheb Phalke Award in 2013.

Why: The Jnanpith Award is a standard question in UPSC Prelims (GS-I — Art & Culture) and all major competitive exams. Key facts: 58th edition; Sanskrit — Jagadguru Ramabhadracharya; Urdu — Gulzar; venue — Vigyan Bhawan; prize — ₹11 lakh + Vagdevi statue; instituted — 1965. Gulzar’s prior honours (Oscar, Dadasaheb Phalke) and Ramabhadracharya’s Chitrakoot connection are likely MCQ extensions. The language–recipient pairing is the most common exam trap, so internalise it carefully.

What: The Organisation of the Petroleum Exporting Countries (OPEC) released its May 2025 Oil Market Report projecting India’s oil demand at 5.74 million barrels per day (mbpd) in 2025 — a growth of 3.39% year-on-year. By 2026, India’s demand is projected to rise further to 5.99 mbpd. India is ranked the 3rd largest oil consumer globally, behind the USA (20.5 mbpd) and China. Notably, India’s demand growth rate of 3.39% outpaces China’s growth rate of approximately 1.5%, reflecting India’s comparatively faster economic expansion and rising energy needs.

How: India’s growing oil demand is driven by rapid urbanisation, expanding vehicle ownership (particularly two-wheelers and commercial vehicles), industrial growth, and petrochemical feedstock requirements. As India is not a member of OPEC, the report reflects an external assessment of India’s energy trajectory. India imports approximately 85% of its crude oil requirements — making it highly dependent on global oil markets and price fluctuations, which is why OPEC data on India carries significant policy relevance for energy security planning.

Why: OPEC reports and India’s energy data are tested in UPSC Prelims (GS-III — Energy, Economy) and Banking Awareness. Key facts: India’s 2025 oil demand — 5.74 mbpd; 2026 projection — 5.99 mbpd; India’s rank — 3rd globally; growth rate — 3.39%; USA (1st, 20.5 mbpd); China (2nd). India’s ~85% crude import dependence and the strategic importance of energy security link this to broader Mains themes on India’s foreign policy (Gulf relations, oil diplomacy) and economic vulnerability to commodity price shocks.

What: The Geographical Indication (GI) Registry, Chennai, granted a GI tag to the Sangri bean from Rajasthan. The Sangri is a pod that grows on the Khejri tree (Prosopis cineraria) — the state tree of Rajasthan — and is the key ingredient in ‘Kher Sangri’, a traditional Rajasthani dish that is deeply embedded in the desert cuisine of the region. The GI application was filed by Swami Keshwanand Rajasthan Agricultural University (SKRAU), Bikaner in January 2025. Uttar Pradesh currently leads India’s GI product count with 77 registered products.

How: A Geographical Indication (GI) tag under the Geographical Indications of Goods (Registration and Protection) Act, 1999 certifies that a product originates from a specific geographic region and possesses qualities, reputation, or characteristics attributable to that origin. The GI Registry is administered by the Office of the Controller General of Patents, Designs and Trade Marks (CGPDTM) under the Department for Promotion of Industry and Internal Trade (DPIIT). Once tagged, only producers from the designated region can use the GI label, protecting against misuse and supporting rural livelihoods.

Why: GI tags are a recurring and growing topic in UPSC Prelims (GS-I — Art & Culture, GS-III — Economy) and State PSC exams. Key facts: Sangri bean GI tag — Rajasthan; host tree — Khejri (state tree of Rajasthan); dish — Kher Sangri; applicant — SKRAU, Bikaner; GI Registry — Chennai; UP leads with 77 GI products; governed by GI Act, 1999. The link between the Khejri tree’s cultural significance (Bishnoi community’s 1730 Khejarli massacre protecting Khejri trees) and the Sangri bean adds a rich Mains interview dimension.
