UPSC Current Affairs 02 June 2026

• Signed on December 18, 2025, in Muscat, the trade pact went live after both countries successfully wrapped up their domestic ratification and internal processes.
• This agreement is a monumental breakthrough as it represents Oman's first bilateral free trade pact since 2006 (when it signed one with the US), and India's second major CEPA in the Gulf region after its landmark 2022 deal with the UAE.

• Trade Baseline: Bilateral trade between the nations surged to USD 11.18 billion in FY 2025–26, showing clear momentum from USD 10.61 billion in the prior fiscal year.
• Duty-Free Access for India: Oman is providing 100% duty-free market access on 98.08% of its tariff lines. This covers a staggering 99.38% of Indian exports by value.
• Immediate Benefits: Unlike older trade pacts that phased out tariffs slowly, 97.96% of these zero-duty concessions went live on Day One (June 1, 2026).
• India's Reciprocal Concessions: In return, India will lower or eliminate customs tariffs on 77.79% of its tariff lines, making up roughly 94.81% of its imports from Oman by value.
• Exclusion List: India has carefully maintained strict "red lines" to shield domestic industries. Gold, silver, and dairy products are completely excluded from tariff cuts.

• Indian Merchandise: Major boosts are expected for labour-intensive and high-volume sectors like textiles, engineering goods, pharmaceuticals, automobiles, plastics, gems and jewellery, and agricultural products.
• Marine Sector: Indian seafood (like shrimp and fish) previously faced import duties up to 5%. They now enjoy instant zero-duty access, heavily benefiting coastal processing jobs.
• Pharma Fast-Tracking: Medical products already cleared by major regulatory bodies (like the USFDA or UK MHRA) will receive expedited 90-day marketing approvals in Oman.
• Traditional Medicine: In a historical first for an Indian trade deal, provisions for AYUSH (traditional medicine) and organic certifications have been incorporated into the core trade framework.

• Massive Services Push: Oman has opened deep market access across 127 services sub-sectors, spanning IT, healthcare, education, R&D, and engineering.
• 100% FDI: Indian firms are permitted 100% Foreign Direct Investment (FDI) to establish operations in key Omani service hubs.
• Longer Stays for Professionals: Contractual service providers and Indian professionals can now secure longer work visas, with stays extendable up to 4 years.

• Gateway to the West: Oman's geographical position near the Strait of Hormuz transforms its ports into a strategic regional hub. This gives Indian goods easier transit into the wider Gulf Cooperation Council (GCC), East African, and European markets.
• Energy Security: The trade pact builds a deeper economic corridor that secures critical oil, gas, and petrochemical supply chains. It also aligns with major planned trans-regional projects like the Middle East–India Deepwater Pipeline.
• Diaspora Connection: The deal directly cushions the economic interests of over 6 to 7 lakh Indian nationals residing in Oman, who generate roughly USD 2 billion in annual remittances back home.

• Commencement of Nominations: June 1, 2026, starting at 11:00 AM.

• Bihar Legislative Council: Features 9 biennial election seats alongside 1 separate bye-election seat.
• Karnataka Legislative Council: Features 7 biennial election seats up for grab.

• Indirect Election System: Neither of these elections involves direct public voting. Representatives to the Council of States and State Legislative Councils are chosen indirectly by already elected MLAs via a system of proportional representation using a single transferable vote.
• Significance for Coalitions: These specific June cycles are mathematically vital for major political alliances (like the NDA and INDIA blocs) to adjust or defend their seat balances within the Upper House of Parliament.

• The Core Agency: It is a specialized, crucial regional deployment of the Border Roads Organisation (BRO) operating under the Ministry of Defence, Government of India.
• Historical Background: Established on June 1, 1990, Project UDAYAK was formed by carving out and restructuring task forces (48 Border Roads Task Force and 752 Border Roads Task Force) from the older Project Vartak and Project Sewak.
• Meaning of the Name: It was aptly named "Udayak," meaning "The Rising Sun," because the very first rays of sunlight hitting India fall directly across its operational area.
• Area of Responsibility (AOR): The project manages a massive network of over 1,457 kilometers of roads. Its geographical jurisdiction covers critical, far-flung eastern districts including Anjaw, Lohit, Dibang Valley, Longding, Tirap, and Changlang in Arunachal Pradesh, alongside parts of Upper Assam.

• Double-Border Monitoring: Project UDAYAK is strategically vital for national security as it enhances connectivity and builds infrastructure concurrently along both the Line of Actual Control (LAC) with China and the international Indo-Myanmar Border.
• Last-Mile Delivery: Having completed baseline inter-valley connectivity, the project has transitioned to constructing forward-most roads to provide uninterrupted tactical access right up to the LAC.
• Border Fencing Operations: Beyond roads, the project is actively executing critical border fencing infrastructure along the Myanmar border to mitigate illegal crossings and secure the regional perimeter.
• Flagship Alignment: It serves as a primary executive arm for the Arunachal Pradesh package under the Strategic Arunachal Region Development Programme (SARDP-NE) and the nationwide Bharatmala Project.

• Major River Crossings: The project has constructed massive, complex bridges over turbulent rivers to slash civilian and troop transit times. Key examples include:
  • The 763.50-meter Pasighat Bridge over the Siang River.
  • The 410-meter Brahmakund Bridge over the Lohit River.
  • The 637.60-meter Noadhing Bridge and the 426.60-meter Diffo Bridge.
• Recent Deliveries: In recent infrastructure boosts, a collective cache of assets built by UDAYAK—comprising 12 bridges, one major road, and a tactical helipad—was formally dedicated to the nation by Defence Minister Rajnath Singh.
• Defence & Aerospace Support: The project successfully executed the complex structural resurfacing of the Dibrugarh Airfield and constructed essential logistical bases for the Assam Rifles and the Special Bureau (SB).

• Green Road Technology: Underlining sustainability, the project pioneered "green asset creation" by resurfacing a 1-kilometer stretch of the Roing-Koronu-Paya road using shredded plastic mixed into the asphalt concrete.
• Social Welfare: The project actively impacts local tribal communities by setting up infrastructure like an 80-bedded hospital at Pullong, organizing regular health outposts, and connecting previously isolated enclaves to main economic markets.

• Hosted virtually by India's Department of Animal Husbandry & Dairying (DAHD) from Krishi Bhawan, New Delhi, the dialogue united policymakers, researchers, and global experts across BRICS nations to establish an integrated framework for future-ready, resilient food systems.

• Fostering BRICS Cooperation: The platform acts as a critical mechanism for international collaboration among BRICS member states (including Brazil, Russia, India, China, South Africa, Iran, Egypt, Ethiopia, and the UAE).
• Tackling Global Challenges: It explicitly targets urgent bottlenecks in global farming, such as low livestock productivity, acute feed shortages, emerging transboundary animal diseases, and severe climate change impacts.
• Knowledge and Best Practice Exchange: Countries shared successful case studies on animal nutrition, sustainable feed formulation, and advanced genetic or digital applications to empower smallholder farmers globally.

• Precision Livestock Farming (PLF): Utilizing on-animal wearables, IoT sensors, thermal imaging, and acoustic monitoring to dynamically track animal health parameters.
• AI-Driven Management: Deploying Artificial Intelligence to run micro-planning frameworks, optimizing green fodder-to-dry feed ratios based on individual animal profiles.
• Early Disease Detection: Implementing automated tech like rumen biosensors to continuously track ruminal pH and temperature, helping detect conditions like mastitis or metabolic issues early.
• Robotics and Automation: Deploying autonomous milking robots and automated feeding machines to cut down intensive manual labour while optimizing operational accuracy.

• Nutritional Value Upgrades: Utilizing specialized biochemical feed technology to safely treat and convert low-grade raw materials or agricultural by-products into high-value animal diets.
• Climate-Smart Feed Solutions: Promoting institutional research on drought-resilient fodder options and sustainable feed formulations that systematically lower methane and greenhouse gas emissions from cattle.

• Digital Transformation: India showcased its flagship National Digital Livestock Mission (NDLM) via the Bharat Pashudhan platform, demonstrating how data-driven architectures can successfully catalogue millions of animals.
• Blockchain and Farmer Apps: The country highlighted its digital ecosystem comprising open-source Enterprise Resource Planning (ERP) systems for milk unions, blockchain-based traceability, and direct-to-farmer apps.
• Sustainable Green Energy: The National Dairy Development Board (NDDB) presented its efforts in scaling up biogas generation, organic manure adoption, and clean energy logistics to optimize smallholder dairy value chains.

• Jointly introduced with the Ministry of Jal Shakti during the National Workshop on R&D in Water in New Delhi, this mission-mode initiative provides substantial funding (up to ₹20 crore per selected multidisciplinary consortium) to support startups, MSMEs, and smaller universities developing high-impact tech solutions for water security.
• Furthermore, ANRF is actively rolling out a series of nationwide reforms, including the Advanced Research Grant (ARG) 2026 and the Catalytic Partnership Program, aimed at democratising research funding away from elite labs to local colleges and private enterprises.

• Statutory Body: ANRF is India's apex statutory organization established under the Anusandhan National Research Foundation Act, 2023. It formally replaced and dissolved the older Science and Engineering Research Board (SERB).
• Leadership: The foundation is uniquely presided over by the Prime Minister of India, who acts as the President of the Governing Board, alongside the Union Ministers of Science & Technology and Education.
• Policy Mandate: Formulated as a pillar recommendation of the National Education Policy (NEP) 2020 (Chapter 17), ANRF aims to drive India's advancement into a global Research, Development, and Innovation (RDI) powerhouse aligned with Viksit Bharat 2047.

• Democratising Funding: A central pillar of ANRF is changing the historical norm where research funds primarily flowed to a few premier institutes (like IITs or IISc). It intentionally funnels resources into state universities, tier-2/tier-3 colleges, and nascent startups.
• Bridging Academia and Industry: The apex framework acts as an active liaison, forging direct public-private partnerships (PPPs) between academic researchers, government labs, philanthropic capital, and corporate industries.
• Diverse Disciplines: Beyond natural, mathematical, and engineering sciences, ANRF is legislated to fund interdisciplinary research, humanities, social sciences, and agricultural development.

• MAHA Water Mission (New June 2026): A ₹200-crore funding drive supporting Technology Readiness Level (TRL-2 to TRL-6) pathways across 5 key water areas: resource management, drinking water, water quality, circular economy, and climate adaptation.
• MAHA Framework: The Mission for Advancement in High-impact Areas (MAHA) drives problem-solving research in high-priority technological sectors including Drones, Electric Vehicles (EVs), MedTech, and 6G infrastructure.
• Advanced Research Grant (ARG) 2026: A newly launched, simplified grant system that abolishes the rigid 50% mandatory cost-sharing requirement for National Labs, drastically cutting red tape for applicants.
• Leapfrog Demonstrators: Active funding calls designed to scale up translational, ready-to-deploy prototypes out of institutional incubation cells.
• Catalytic Partnership Program: A dedicated funding route focused on building institutional-level ecosystems through private capital match-funding.

• Whole-of-Government Approach: Breaking down vertical silos, ANRF pools financial resources from multiple separate central ministries to avoid overlapping efforts and build consolidated national programs.
• Low-Interest Financing: Through its RDI scheme, it intends to offer long-term financial assistance at low interest rates to spark high-volume commercial R&D spending within India's private sector.

• Alternative Identity: The watercourse is widely known as the Kura River in Turkish and Azerbaijani nomenclature.
• Longest Regional River: It holds the distinction of being the longest river in the South Caucasus mountain region.
• Total Length: The river spans a total length of 1,515 kilometers across three countries:
  • Azerbaijan: 906 kilometers (the longest stretch)
  • Georgia: 270 kilometers
  • Turkey: 174 kilometers
• Course and Flow: It is an east-flowing river that originates in the volcanic highlands near Kars in northeast Turkey. It cuts through Georgia in a sweeping arc, progresses between the Greater and Lesser Caucasus mountains, and moves through Azerbaijan before finally emptying into the Caspian Sea.
• Principal Cities: Tbilisi, the capital city of Georgia, stands as the largest and most populous urban hub situated directly along its banks.
• Primary Tributary: The Araxes (Aras) River serves as the largest and most critical tributary feeding into the Mtkvari.

• Cradle of Civilization: Human settlements along the fertile banks of the Mtkvari River basin date back directly to the Bronze Age.
• Ancient Strategic Trade Route: Historically, the river functioned as a vital transport corridor linking the remote Caucasus mountains to broader, high-traffic Eurasian trade lines.
• Classical Antiquity: In historical texts from the Greco-Roman era, the river was widely documented and recognized under the name Cyrus.

• Agricultural Lifeline: Since ancient times, the river has been deeply utilized to sustain intensive irrigation agriculture across the South Caucasus.
• Severe Sewage Pollution: The river faces profound environmental degradation primarily because municipal untreated sewage from densely populated districts discharges directly into the waters through outdated drainage channels.
• Disappearing Ecosystems: Heavy industrial runoff, coupled with unchecked agricultural waste, has drastically altered the river's water quality, leading to the total disappearance of several native fish species.
• International Cooperation: Recognizing its transboundary fragility, Georgia and Azerbaijan operate under negotiated frameworks backed by the United Nations Economic Commission for Europe (UNECE) to co-manage, monitor, and safeguard the river basin's resources.

• In the case State of Himachal Pradesh & Ors. v. M/s Kundlas Loh Udyog, a bench comprising Justice J.B. Pardiwala and Justice K.V. Viswanathan ruled that the doctrine cannot be invoked to claim fiscal incentives or concessions under a government policy that was never intended to benefit that specific category of industry.
• The ruling directly addresses a critical friction point between private industrial investments and the State's administrative flexibility to design targeted economic policies.

• Definition: Promissory estoppel is a legal principle stating that if a party makes a clear, unambiguous promise to another, and the second party reasonably relies on it and changes their position to their detriment, the promisor cannot go back on their word.
• Foundation: It is an equitable doctrine rooted in fairness, moral conscience, and justice, rather than rigid statutory contract law.
• Application Against the State: In India, the doctrine is predominantly used to hold government bodies accountable to their administrative promises, such as tax holidays or industrial incentives.
• Enforceability Without Contract: It does not require a formal, written contract to be legally binding, provided all criteria of reasonable reliance are fully satisfied.

• Intent Precedes Harm: The Court ruled that even if an industrial unit suffers financial loss or invests heavily, it cannot claim benefits if the policy’s underlying intent was never meant for its category.
• The Case Specifics: The respondent, an existing enterprise that underwent substantial expansion, tried to claim concessional electricity charges meant strictly for new industrial units. The Court rejected this claim.
• No Distortion of Policy: The doctrine cannot be stretched to force the State to grant fiscal subsidies contrary to the actual language and scope of its policy framework.
• Unconscionable Departure Required: For the doctrine to succeed, the aggrieved party must prove that the state's sudden shift from its word is highly unconscionable and unjust.

1. Clear and Unambiguous Promise: The representation made by the state must be precise and unequivocal.
2. Reasonable Reliance: The plaintiff must have actively altered their conduct or business decisions based on that exact promise.
3. Detriment or Loss: The promise must suffer an injury, financial loss, or legal disadvantage if the promise is broken.
4. Public Interest Override: The doctrine cannot be applied against legislative actions, nor can it force a government to execute something contrary to law or dominant public interest.

• Union of India v. Indo-Afghan Agencies (1968): The Supreme Court first applied the principle against erratic executive actions of governmental authorities.
• Motilal Padampat Sugar Mills v. State of Uttar Pradesh (1979): A foundational case where the UP government promised a 3-year sales tax exemption for new plants. When the state tried to retract it, the Supreme Court bound them to their initial promise, solidifying the doctrine's strength.
• Chhaganlal Keshavalal Mehta v. Patel Narandas Haribhai (1981): Established the strict multi-point structural test for courts to evaluate estoppel claims.

• This critical amendment introduces strict modifications to registration deadlines for foreign nationals, mandates tighter reporting by medical facilities, and introduces key changes for children born to mixed-citizenship couples.
• The rules derive their power from the overarching Immigration and Foreigners Act, 2025, which came into effect on September 1, 2025, to modernise India’s national security and border monitoring framework.

• Revised Registration Deadline: Foreign nationals arriving on a visa valid for 180 days or less must now register any time before the expiry of the 180 days if they intend to extend their stay.
• Elimination of the Grace Period: This completely replaces the previous rule that gave foreigners a flexible buffer of "within 14 days after the expiry of the 180-day period".
• Emergent Clauses Only: Any late registration requested after the 180-day period has passed will now be scrutinized strictly and granted only under emergent circumstances.
• Cumulative Visa Stays: The advanced deadline also binds foreigners holding long-term visas that specify individual stays must not exceed 180 days per single visit or cumulatively within a calendar year.

• Indian Citizen Exemption: The June 2026 notification clarifies that the mandatory 30-day reporting for foreign-born children does not apply if an Indian parent intends to retain Indian citizenship for the child.
• Foreign Citizenship Caveat: If the child subsequently acquires foreign citizenship while in India, parents must report this to the Registration Officer within 30 days.

• Mandatory Reporting: Health facilities must directly report foreign patients' data to Regional Registration Officers to improve tracking.

• The Meaning: The name translates to "King of the Tylosaurs," serving as a direct nod to the land-dwelling Tyrannosaurus rex.
• The Parallel: Just as the land T. rex dominated terrestrial ecosystems as an apex carnivore, Tylosaurus rex sat at the absolute top of the marine food chain, capable of tearing apart anything it caught.
• Not Contemporaries: Despite sharing the "rex" title, the two creatures were not contemporaries. Tylosaurus rex ruled the oceans roughly 80 million years ago during the Late Cretaceous Period, pre-dating the land T. rex by millions of years.

• Immense Size: Stretching up to 43 feet (13.2 metres) long, it was the length of a modern school bus. This makes it nearly twice the size of today's largest great white sharks and slightly longer than "Sue", the largest known land T. rex fossil.
• Flesh-Slicing Teeth: Unlike most other mosasaurs, Tylosaurus rex possessed finely serrated teeth explicitly engineered to slice cleanly through thick bone and meat, rather than just gripping prey.
• Heavy Musculature: Its skull featured distinct bone adaptations that supported unusually powerful jaw and neck muscles, allowing it to crush animal skulls and subdue giant marine prey.
• Body Structure: It possessed a highly streamlined body, an elongated snout, four large paddle-like flippers, and a powerful shark-like tail fluke built for swift ambush hunting in open waters.

• The Misidentification: The fossils of Tylosaurus rex were not newly dug up; they had been hiding in plain sight within museum collections for decades. They were long mislabelled as Tylosaurus proriger (a smaller, 31-foot relative).
• The Breakthrough: Paleontologist Amelia Zietlow and her team recognized the mistake after noting stark anatomical differences in size, time periods, and locations.
• The Reassigned Specimens: Several iconic museum fossils have now been officially stripped of their old labels and crowned as Tylosaurus rex, including "Bunker" (University of Kansas), "Sophie" (Yale Peabody Museum), and "The Black Knight" (Perot Museum of Nature and Science, Dallas).

• Extreme Internal Violence: Scientists discovered widespread skeletal trauma on Tylosaurus rex fossils. For instance, "The Black Knight" specimen features a fractured lower jaw and a missing snout tip, providing concrete evidence of vicious, bloody battles against members of its own species.
• Ancient Domain: It hunted in the Western Interior Seaway, a massive prehistoric inland ocean that split the North American continent completely into two landmasses during the Cretaceous era. Most of its fossils are concentrated in North and Central Texas.
• Dietary Habit: It was an opportunistic apex predator that preyed heavily on large fish, sharks, prehistoric sea turtles, and other giant marine reptiles.
• Modern Relatives: Despite looking like an aquatic dinosaur, it was actually a giant prehistoric marine lizard. Its closest living relatives today are monitor lizards (like the Komodo dragon) and snakes.
