• Aviation tragedy: an Air India Boeing 787-8 crashed near Ahmedabad killing 242 people. AAIB leads the investigation under the Chicago Convention framework.
• Law: an ANI versus YouTuber case turned on Section 52(1) of the Copyright Act 1957. Fair dealing and trademark disparagement are both in play.
• Global data: 35.5 per cent of marine fish stocks are overfished (FAO). Carbon pricing covers 28 per cent of global emissions. India is 131st on the WEF Gender Gap Index, slipping two places.
• Geography: Lake Natron in Tanzania is the only regular breeding site for African lesser flamingos. Karnataka and Andhra Pradesh are in a trade dispute over Totapuri mangoes under Articles 301 and 304.

An Air India Boeing 787-8 Dreamliner crashed near Ahmedabad killing all 242 people on board. The Aircraft Accident Investigation Bureau (AAIB) began the investigation immediately.

• AAIB: establishment: the Aircraft Accident Investigation Bureau was set up on 30 July 2012. It operates under the Aircraft (Investigation of Accidents and Incidents) Rules 2017.
• Legal anchor: the Rules are framed under the Aircraft Act 1934. AAIB's methodology follows Annex 13 to the Chicago Convention on International Civil Aviation (1944). Annex 13 sets the global standard for accident investigation.
• Scope: AAIB investigates accidents and serious incidents involving aircraft weighing more than 2,250 kg. Its sole objective is improving safety, not assigning blame or liability.
• Chicago Convention (1944): created ICAO (International Civil Aviation Organization) and established the foundational framework for civil aviation safety standards worldwide.
• India's aviation scale: India is the third-largest domestic aviation market in the world. It handled 37.6 crore passengers in FY24. The number of airports grew from 74 in 2014 to 157 in 2024.
• UDAN Scheme: the regional connectivity scheme that added routes to smaller cities. It covers 583 routes across 86 airports. It is an MoCA (Ministry of Civil Aviation) scheme.
• ICAO safety ranking: India improved from 102nd (2018) to 48th (2022) in ICAO's Universal Safety Oversight Audit Programme ranking. This context matters: the ranking measures systemic safety readiness, not specific accident rates.

A crash of this scale will trigger calls to revisit AAIB independence. The body's investigative mandate is deliberately separate from the DGCA's regulatory mandate. The two must not be conflated in answers.

A case between the news agency ANI and a YouTuber sharpened the contours of fair dealing under Indian copyright law.

• Section 52(1) of the Copyright Act 1957: defines acts that do not constitute copyright infringement. Fair dealing for the purpose of reporting current events, criticism or review is among those acts.
• Four factors courts examine: the purpose and character of the use (is it transformative?), the nature of the copyrighted work, the amount and substantiality of the portion used, and the effect of the use on the potential market for the original work. These four factors are drawn from comparative jurisprudence and applied by Indian courts.
• TV Today vs NewsLaundry: an earlier case that established the precedent for applying fair dealing in a media criticism context. A news channel sought to restrain a commentary channel from using its broadcast clips.
• Trademark disparagement: a separate cause of action. It arises when a person's commercial speech injures the reputation of another's trademark. The ANI case raised this alongside copyright claims.
• De minimis doctrine: the legal principle that the law does not concern itself with trivial matters. A YouTuber using a brief clip may invoke this doctrine when the amount used is minimal relative to the whole work.

The distinction between fair dealing (copyright) and freedom of speech (Article 19(1)(a)) is important for mains. Fair dealing is a statutory defence under an Act; Article 19(1)(a) is a fundamental right. Both may be argued in the same case but they operate on different legal planes.

The Food and Agriculture Organization released the State of World Marine Fishery Resources 2025 at the third UN Ocean Conference (UNOC3) in Nice, France.

• Overall stock health: 64.5 per cent of marine fish stocks are within biologically sustainable levels. That leaves 35.5 per cent overfished. The overfished share has grown steadily from 10 per cent in 1974.
• Deep-sea species: only 29 per cent of deep-sea stocks are sustainably exploited. Deep-sea fisheries are the most vulnerable because species there grow slowly and reproduce late.
• Sharks: 43.5 per cent of shark species assessed are unsustainably fished. Shark finning and bycatch drive this.
• Tuna: 87 per cent of tuna stocks are within sustainable levels. Tuna is among the better-managed groups because of the Regional Fisheries Management Organizations (RFMOs) that govern them.
• UNOC3: the third United Nations Ocean Conference held in Nice, France. It is the main intergovernmental forum for implementing Sustainable Development Goal 14 (Life Below Water).
• India's fisheries rank: India is the third-largest fish-producing country in the world. Marine fisheries contribute significantly to livelihoods in coastal states.

The World Bank's State and Trends of Carbon Pricing 2025 report mapped every operating carbon pricing instrument globally.

• Total instruments: 80 carbon pricing instruments are in operation: 43 carbon taxes and 37 Emissions Trading Systems (ETSs).
• Coverage: these instruments collectively cover 28 per cent of global greenhouse gas emissions. The target needed to keep warming to 1.5 degrees Celsius requires covering far more, faster.
• Revenue: the instruments generate over 100 billion US dollars annually. This revenue funds climate investments, fiscal consolidation or household rebates depending on the country.
• Carbon tax vs ETS: a carbon tax sets a price per tonne of CO2 and lets the market determine the quantity of emissions. An ETS sets a cap on total emissions and lets the market determine the price (via tradeable permits). The EU ETS is the largest by value; British Columbia's carbon tax is often cited as the most studied carbon tax.
• India's approach: India is developing a benchmark-based intensity ETS. Intensity targets reduce emissions per unit of output rather than absolute emissions. This suits an economy where total output is still growing.

The World Economic Forum published the Global Gender Gap Report 2025 covering 148 economies.

• India's rank: 131st out of 148 economies. India slipped from 129th in the previous year. Its overall parity score is 64.1 per cent.
• What the index measures: the report scores four sub-indices: Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment.
• Regional comparison: Bangladesh ranked 24th, the best in South Asia. Pakistan ranked 148th, the worst in the world.
• Time to parity: the report estimates that full gender parity across all four dimensions is 123 years away at current rates of change.
• Political representation decline: the share of Indian female Members of Parliament fell from 14.7 per cent to 13.8 per cent in the latest data. This is the sub-index that pulls India's overall score down most sharply.
• Publisher: the World Economic Forum, the same body that publishes the Global Competitiveness Report and the Global Risks Report. WEF is headquartered in Davos, Switzerland.

The Department of Posts launched the Gyan Post Service under the tagline "Har Ghar Gyan, Har Sapne Ko Udaan."

• What it does: delivers educational books, periodicals and socio-cultural literature to households at subsidised postal rates.
• Weight range: covers packets from 300 grams to 5 kilograms.
• Transport mode: surface transport only. Air and express delivery are not covered.
• Ministry: Department of Posts is under the Ministry of Communications.
• Policy rationale: affordable reading material delivery addresses the last-mile problem for students in rural and semi-urban areas who cannot easily access bookshops.

The Working Group on Avian Checklists published AviList, described as the first unified global checklist of bird species.

• What it solves: before AviList, multiple competing checklists (IOC World Bird List, Clements Checklist, HBW) gave different species counts and names. This created confusion in scientific literature and conservation policy.
• Publisher: the Working Group on Avian Checklists operates under the International Ornithologists' Union.
• Update cycle: annual revisions are planned. The checklist aims to be the single authoritative reference for taxonomy, species splits and lumps.
• Why prelims cares: any question about total bird species globally, or about Indian bird diversity, should be anchored to the most authoritative list available. AviList replaces fragmented citation.

Lake Natron in northern Tanzania surfaced in current affairs as a Ramsar-listed ecosystem under pressure.

• Location: Lake Natron sits in the Gregory Rift Valley in northern Tanzania. The Gregory Rift is the eastern branch of the East African Rift System. The lake lies close to the Kenyan border.
• Chemistry: Natron's pH fluctuates between 5 and 12 depending on season. At its most alkaline it is caustic enough to calcify animals that die in the water. The alkalinity comes from sodium carbonate (natron) and other minerals.
• Source: Ol Doinyo Lengai volcano feeds sodium carbonate-rich ash into the lake's catchment. Ol Doinyo Lengai is the world's only active carbonatite volcano. Carbonatite lava is unusually cool and rich in carbonate minerals rather than silicate.
• Colour: the lake turns deep red in the dry season from halophilic microorganisms (salt-loving bacteria and algae) that thrive in high-alkalinity conditions.
• Flamingos: Lake Natron is the only regular breeding site for African lesser flamingos. The caustic shallows deter most predators. An estimated 1 to 2 million lesser flamingos breed here.
• Ramsar status: the lake is a Ramsar site. Ramsar is the Convention on Wetlands (1971) headquartered in Gland, Switzerland.
• River: the Ewaso Ng'iro River (originating in Kenya) flows into Lake Natron from the north.

A Karnataka-Andhra Pradesh dispute over restrictions on Totapuri mango trade tested the constitutional limits on interstate commerce.

• Totapuri mango: an elongated, parrot-beak-shaped variety grown primarily in Karnataka and Andhra Pradesh. Also called Ginimoothi in Karnataka, Sandersha or Banglora in parts of Andhra Pradesh. It is the primary variety used in India's mango pulp export industry.
• Article 301: provides that trade, commerce and intercourse throughout India shall be free. This is the general right to free movement of goods across state borders.
• Article 304(b): permits a State Legislature to impose reasonable restrictions on the freedom of trade for public interest, but only with prior sanction of the President. This is the exception that Karnataka invoked to restrict Totapuri exports to Andhra Pradesh during peak season.
• The tension: Karnataka wants to ensure domestic processing units get supply. Andhra Pradesh argues this violates Article 301. The case illustrates why Article 304(b) requires Presidential sanction: it prevents states from casually blocking interstate trade under local-interest pretexts.

• UNOC3 in Nice: the third UN Ocean Conference, held in Nice, France, focused on SDG 14 (Life Below Water). India announced enhanced fisheries monitoring commitments at the conference.
• ETS terminology: under an Emissions Trading System, a permit to emit one tonne of CO2-equivalent is called a carbon credit or allowance. The cap declines over time to drive emissions down.
• AAIB independence: AAIB reports to the Ministry of Civil Aviation but is separate from DGCA. DGCA regulates; AAIB investigates. Conflating the two is a common error in exams.
