UPSC CSE Why

1) GPS Jamming & Spoofing Incidents Rising in Aviation What Happened * Global aviation is reporting a sharp rise in GPS/GNSS interference—especially around conflict zones (Middle East, Eastern Mediterranean, Arctic) and recently near major Indian airports including Delhi. * These disruptions affect aircraft navigation, timing and routing. Issue Raised * Jamming: Overpowering a GNSS receiver with strong radio interference, making navigation temporarily unusable. * Spoofing: Deliberately sending counterfeit GNSS signals to mislead the aircraft about position/time. Current Context * MoCA informed Parliament of repeated interference cases around the Delhi airport. * Airlines worldwide reported a 200% rise in GPS signal-loss events (2021–24). * Spoofing is becoming a major safety risk, capable of causing navigational confusion in cockpit systems. Why it Matters for India / UPSC * Safety concerns for civil aviation. * Need for redundancy systems & protected navigation infrastructure. * GNSS vulnerabilities impact national security and aviation reliability. 2) How Mangroves’ Cells Help Plants Survive Saltwater What Happened * New study (Current Biology) reveals specific cell-level traits that allow mangroves to tolerate high salinity. Issue Raised * Saltwater kills most terrestrial plants, but mangroves survive due to specialised cellular adaptations. Current Context * Scientists analysed 34 mangrove species across 17 plant families: * Smaller & more compact cells * Thicker cell walls for mechanical strength * Specialised epidermal cells for salt expulsion * Waxier roots in some species to exclude salt * Mangroves also excrete salt through leaf glands. Why it Matters for India / UPSC * Helps develop salt-tolerant crops (critical under climate change & sea-level rise). * Mangrove ecosystems protect coasts, support biodiversity, and prevent erosion. 3) Sacred Claims: The Preah Vihear Temple Dispute (Thailand–Cambodia) What Happened * Ongoing border tensions over the Preah Vihear temple, a UNESCO World Heritage site, revived by recent political statements. Issue Raised * Dispute centres on ownership of the plateau surrounding the temple, though ICJ had already ruled. Current Context * Temple built by Khmer kings (9th–12th century), dedicated to Shiva. * ICJ rulings: * 1962: Temple belongs to Cambodia. * 2013: Cambodia also owns the entire promontory; Thailand must withdraw security forces. * Border clashes have occurred intermittently, sometimes killing dozens and displacing thousands. Why it Matters for India / UPSC * Example of international boundary disputes + role of ICJ in conflict resolution. * Illustrates how colonial-era cartography fuels modern tensions. * Important for GS-1 (World Heritage), GS-2 (IR), and Essay.

1) Diwali inscribed on UNESCO Intangible Cultural Heritage List What happened UNESCO has added Diwali (Deepavali) to its *Representative List of Intangible Cultural Heritage of Humanity* in 2025. India presented the nomination during a key UN meeting in New Delhi. Issue raised The need to globally recognise India’s living cultural traditions, beyond monuments, and preserve intangible heritage such as rituals, festivals, crafts, and oral traditions. Current context * Diwali becomes India’s 16th element on the list. * Other listed traditions include Garba (Gujarat) and Durga Puja (West Bengal). * UNESCO’s ICH list strengthens cultural diversity and human creativity. * India plans additional nominations, including Bihar’s Chhath Puja. Why it matters * Boosts tourism & soft power. * Helps access UNESCO’s safeguarding funds. * Supports artisan livelihoods and encourages inter-cultural dialogue. 2) Debate on immunity for CEC & Election Commissioners What happened Rahul Gandhi accused the Election Commission of “colluding with the government” and criticised the retrospective legal immunity granted to the CEC and ECs under the *CEC Appointment Act, 2023*. Issue raised Clause 16 grants complete protection from civil/criminal proceedings for actions done while serving as CEC/EC — raising questions of accountability. Current context * Rahul Gandhi claims the law could shield ECs from scrutiny. * Opposition demands amendments and potential *retroactive action* against previous ECs. * Government says immunity is necessary to ensure independence and fearless decision-making. Why it matters This debate centres on institutional autonomy, checks & balances, and public trust in elections. 3) Space spectrum war: New global competition for satellite frequencies What happened Countries, companies, and global agencies are competing for limited satellite spectrum and orbital slots as megaconstellations (Starlink, OneWeb, Kuiper) expand rapidly. Issue raised Unregulated expansion could cause * orbital congestion * radio interference * debris multiplication * inequality in access to satellite internet. Current context * ITU allocates global satellite spectrum and orbital positions. * India seeks a larger share due to rising satellite broadband demand. * Starlink alone used 5,000+ satellites and reached 630,000 terminals globally. * Industry experts warn of “digital colonialism” if spectrum is captured by few players. Why it matters Spectrum allocation affects: * national security * digital sovereignty * telecom infrastructure * future global internet governance. 4) Govt clarifies: Marine Protected Areas not part of offshore mining blocks What happened The Centre said no Marine Protected Areas (MPAs) are included in the 30 offshore blocks proposed for private mining. Issue raised Widespread protests in Kerala & coastal regions argue that seabed mining would destroy marine ecosystems and harm fisher livelihoods. Current context * India has notified 130 MPAs. * 23 offshore blocks proposed — including sand, lime mud, polymetallic nodules. * Offshore Areas Mineral Trust formed with coastal States on its governing body. * Govt says environmental impact assessments + mitigation will be mandatory. Why it matters This debate links: * blue economy policies * biodiversity protection * coastal community rights * sustainable mineral extraction.

1. Govt panel recommends AI companies pay royalties to creators What happened * DPIIT-led committee released a working paper proposing mandatory royalty payments by AI companies to copyright holders. * Recommends creating a statutory licensing system with government-approved fixed rates. Issue raised * AI systems are training on copyrighted material (news, images, text) without consent or compensation. * Publishers unhappy with current voluntary licensing practices (e.g., OpenAI). * Concerns over AI-generated content competing with original creators. Current context * Paper suggests: * Statutory license for AI training. * Centralised royalty collection via copyright societies (like music industry). * Rates revised every 3 years. * Applies retrospectively unless exempt. * Indian news publishers (DNPA) support strong copyright protection. * Global debate intensifying — EU, US grappling with AI copyright. Why it matters * Big move toward regulating generative AI in India. * Balances innovation vs copyright protection. * Sets up India as the first country to propose statutory royalties for AI training. * Relevant for GS3: IP rights, tech regulation, digital economy. 2. Israel’s “Yellow Line” that may define Gaza border What happened * Israeli military chief referenced a “Yellow Line” — a forward defensive line dividing Israeli-controlled Gaza from the rest. * Could signal Israel’s intention to retain long-term control over more than half of Gaza. Issue raised * Undermines current ceasefire plan involving phased withdrawal. * Risks derailing US-backed 20-point ceasefire roadmap. Current context * Ceasefire’s first phase nearing completion; Israel expected to withdraw except from border buffer zone. * No clarity on timeline for further withdrawals. * Statements indicate Israel may not return territory as expected. Why it matters * Impacts Middle East peace prospects, humanitarian situation. * Shifts geopolitical balances: US, Arab states, Palestinian Authority involved. * Relevant for GS2: International relations, Israel-Palestine conflict. 3. Blue-Corner Notice issued against Goa club owners What happened * Interpol issues a Blue Corner Notice for Saurabh and Gaurav Luthra, owners of the club where a fire killed 25 people. * They fled India; believed to be in Thailand. Issue raised * Blue Notices help states locate, identify or obtain information about suspects. * Fire raises questions on criminal negligence, licensing, safety violations. Current context * CBI requested Interpol notice. * Blue notices often precede Red Corner Notices depending on evidence. Why it matters * Highlights India’s engagement with Interpol mechanisms. * Brings focus on urban safety norms, fire regulation failures. * Relevant for GS2: International policing cooperation; GS3: disaster management. 4. Does Google’s Quantum Echoes bring Q-day closer? What happened * Google used a 65-qubit processor ("Willow") to study “Quantum Echoes” — how quantum information refocuses after disturbances. Issue raised * Speculation whether this advances Q-day — when quantum computers can break RSA encryption. Current context * Findings improve understanding of quantum information behaviour but do NOT break encryption. * Experts estimate breaking RSA-2048 would need millions of logical qubits, decades away. * Governments shifting to post-quantum cryptography (PQC) as precaution. Why it matters * Quantum computing = major strategic tech (cybersecurity, defence, communication). * Reinforces urgency for quantum-safe encryption. * Useful for GS3: Science & Tech; cybersecurity.
