Election Commission splits the SIR declaration from Form 6
Must knowGS-2
The Election Commission has taken the Special Intensive Revision declaration out of the online version of Form 6 on its ECINet portal in the states where the revision is still under way. The declaration, which was inserted between Sections J and K of the online enrolment application, asked applicants to state whether their own name, or that of a parent or grandparent, appeared in the electoral roll during the last intensive revision in the early 2000s, or whether none of them did. It will now be available as a separate form.
The move follows a decision of the Commission's Electoral Roll Division dated October 21, disclosed in a counter-affidavit filed before the Supreme Court on October 26. The affidavit said the declaration had been placed inside Form 6 so that an applicant would generate a single one-time password and a single electronic signature instead of two, and that this objective became a subject of deliberation. It is the third position the Commission has taken on Form 6 in six weeks, and it reverses an arrangement that two Election Commissioners had objected to in internal notes, one of them calling it unauthorised.
Separately, the Commission clarified on November 3 that voters whose names appeared in earlier rolls but are missing from draft rolls published during the revision can apply afresh through Form 6. It said such an application is not by itself a false declaration merely because the voter was previously enrolled, and directed electoral registration officers not to start proceedings under Section 31 of the Representation of the People Act, 1950, solely for filing the form, provided the applicant is not enrolled in another constituency and the declaration otherwise follows the law.
For Prelims, remember the basics: Form 6 is the application for inclusion of a name in the electoral roll, a Special Intensive Revision is a house-to-house re-verification of the rolls, and Section 31 of the 1950 Act penalises false declarations in connection with electoral roll entries. The clarification follows a Delhi High Court order of October 14 in the Nilotpal Datta case.
For Mains, this episode is about institutional credibility as much as procedure. Repeated reversals on the same form, coming after recorded internal dissent, test public trust in a process whose legitimacy depends on being seen as rule-bound. At the same time, the clarification protects the core democratic interest at stake: no eligible voter should be kept off the roll by fear of prosecution for re-applying after a revision dropped their name.

QS Asia 2027: India's top universities slip even as its footprint grows
Must knowGS-2
India has 325 universities in the QS World University Rankings: Asia 2027, up from 294 last year, making it the second-most represented higher education system in the region after mainland China. But the headline growth masks a slide at the top: nearly 71 per cent of Indian institutions ranked last year fell this time, and no Indian institution made the top 50 for the second year in a row.
The country's highest-ranked institution, IIT Delhi, fell seven places to 66th from 59th. The Indian Institute of Science, Bengaluru, dropped 15 places to 79th from 64th, IIT Bombay slipped to 83rd from 71st, IIT Madras to 85th from 70th, IIT Kharagpur to 90th and IIT Kanpur to 97th. The University of Delhi fell out of the top 100, moving to 106th from 95th. The edition covers 1,722 universities across 26 higher education systems.
The picture is not uniformly bleak. India leads Asia on research output per faculty member: IISc Bengaluru ranks first in the region on the papers-per-faculty indicator, and five Indian institutions feature in the regional top 10 on that measure. Rankings are relative, so an institution can fall even when its own score improves, if its peers improve faster.
For Prelims, note that QS stands for Quacquarelli Symonds, a London-based higher education analyst, and that its Asia rankings weigh academic reputation, employer reputation, research impact and internationalisation, among other indicators.
For Mains, the contrast is the point. India produces research volume at scale but loses ground on reputation and internationalisation, the two indicators that most reflect how the world's academics and employers perceive its universities. Closing that gap is the real test of the National Education Policy's internationalisation agenda, and it cannot be met by adding ranked institutions alone.
US strikes Iranian targets in the Strait of Hormuz as talks stay alive
Must knowGS-2
The United States has conducted defensive strikes on some Iranian targets in the Strait of Hormuz, according to a US official, in the latest flare-up around the narrow waterway that links the Persian Gulf to the Gulf of Oman. The strikes were reported as Americans voted in midterm elections.
Even as the strikes were disclosed, the diplomatic track was kept visibly open. Vice-President J. D. Vance told reporters he had just spoken to President Donald Trump about talks with Iran, and said both felt reasonably good about the prospects of reaching a negotiated settlement.
For Prelims, fix the geography: the Strait of Hormuz separates Iran from Oman and the United Arab Emirates, and it is one of the world's most important oil chokepoints, carrying a large share of seaborne petroleum shipments. Any disruption there feeds directly into global crude prices.
For Mains, read the two signals together. Strikes and settlement talk are not contradictory here; they are parallel instruments, with force used to shape the terms of negotiation. For India, which imports most of its crude, the stakes are energy security and shipping costs, and the episode underlines why diversification of supply and strategic reserves remain live policy concerns rather than settled ones.

World court to rule on November 19 in the Rohingya genocide case
Must knowGS-2
The International Court of Justice will rule on November 19 on the case brought by The Gambia against Myanmar over its treatment of the Rohingya. Judges at the court in The Hague have spent seven years weighing accusations that Myanmar's repression of the Rohingya breached the 1948 United Nations Convention on the Prevention and Punishment of the Crime of Genocide.
The Gambia filed the case in 2019, arguing that Myanmar's campaign against the Rohingya minority, which drove hundreds of thousands of people into Bangladesh, violated its obligations under the Genocide Convention. The court's ruling will address whether Myanmar breached the convention, after it had already ordered provisional measures in 2020 directing Myanmar to prevent genocidal acts.
For Prelims, remember the institutional facts: the International Court of Justice is the principal judicial organ of the United Nations, seated at The Hague, with 15 judges. The Genocide Convention of 1948 allows a state party to bring another state party before the court for alleged breaches, even without being directly injured.
For Mains, the case tests both the reach and the limits of international law. A ruling against Myanmar would be a landmark on state responsibility for atrocities, but the court has no enforcement arm of its own, so compliance would depend on political pressure through the Security Council and member states. For India, the case sits alongside the continuing refugee burden on Bangladesh and the wider question of stability in its eastern neighbourhood.
Ganga treaty clock runs down with no renewal yet
Must knowGS-2
With weeks to go before the Ganga Water Treaty expires, the Ministry of External Affairs has said a structured mechanism remains in place for the pact, while confirming there is no update yet on its renewal or on dates for a visit by the Bangladesh Prime Minister, whom India has invited to New Delhi. The 1996 treaty, signed for 30 years, lapses on December 12, 2026.
The treaty governs sharing of the Ganga's waters at the Farakka Barrage during the dry season, from January 1 to May 31, using a formula based on ten-day cycles. It has no automatic renewal clause, so without a fresh agreement or an extension, the agreed allocation framework falls away. Bangladesh has pressed for a new or revised treaty with an explicit guarantee of its share, similar to the 1977 arrangement, while voices in Bihar have urged the Centre not to renew the treaty in its current form.
For Prelims, note the essentials: the treaty was signed on December 12, 1996, it covers sharing at Farakka, and India and Bangladesh share 54 transboundary rivers, of which the Ganga is the only one covered by a 30-year water-sharing treaty. The Joint Rivers Commission is the bilateral body for river cooperation between the two countries.
For Mains, this is hydro-diplomacy under pressure. Falling dry-season flows, climate stress and changed politics on both banks make a simple rollover harder than it was in 1996, yet failure to reach a new arrangement before expiry risks eroding mutual confidence and complicating the wider bilateral relationship. A revised treaty that pairs allocation with ecological flows, data sharing and flood management would be worth more than a bare extension.
Supreme Court to test facial recognition on protesters
Must knowGS-2
The Supreme Court is set to examine whether police can use facial recognition technology on protesters, taking up a question that sits at the intersection of public order policing and the fundamental right to privacy. The issue arises from the use of cameras and matching software to identify people at protest sites.
The case will test how far the state may go in identifying participants in a demonstration. Supporters of the practice argue it helps maintain order and identify lawbreakers, while critics say the knowledge that one's face is being scanned and stored chills participation in lawful protest itself.
For Prelims, the anchor is the Puttaswamy judgment of 2017, in which a nine-judge bench recognised privacy as a fundamental right under Article 21, and laid down that any intrusion must satisfy legality, legitimate aim and proportionality. Article 19 protects the freedom to assemble peaceably and without arms.
For Mains, the absence of a dedicated law governing facial recognition is the gap to examine. Unlike a targeted investigation, scanning a crowd treats every participant as a suspect by default, and errors in matching carry real consequences for individuals. The court's answer will shape whether India regulates this technology by statute, with safeguards and oversight, or leaves it to executive discretion.
India hosts the first BIMSTEC maritime security exercise at Sri Vijaya Puram
Must knowGS-2
India is hosting the first BIMSTEC Maritime Security Exercise at Sri Vijaya Puram in the Andaman and Nicobar Islands, with all seven members of the grouping taking part. The theme is "Shared Seas, Shared Security and Shared Prosperity", and the exercise was announced by the Prime Minister at the 6th BIMSTEC Summit in Thailand in 2025.
The participants are Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka and Thailand, so the exercise includes two landlocked states with no navies, which underlines that BIMSTEC is a whole-region platform rather than a naval club alone. The Andamans sit astride the approaches to the Malacca Strait, and the Andaman and Nicobar Command, India's only tri-service command, is the natural host. BIMSTEC's secretariat is in Dhaka, and the grouping links five South Asian and two Southeast Asian states around the Bay of Bengal.
For Prelims, anchor the firsts and the place: the first BIMSTEC Maritime Security Exercise, Sri Vijaya Puram, seven participants, the theme Shared Seas, Shared Security and Shared Prosperity, the announcement at the 6th BIMSTEC Summit, and the secretariat in Dhaka.
For Mains, the exercise matters for neighbourhood policy and maritime domain awareness in the Bay of Bengal, where piracy, trafficking and grey-zone activity make cooperative surveillance a shared interest. The constraint is BIMSTEC's uneven capacity: political breadth is easier than joint operations, and the grouping still has to prove it can turn a first exercise into a standing security habit.

FRRO network reaches 20, with every State capital covered by 2027
Must knowGS-2
The Home Ministry has expanded the Foreigners Regional Registration Offices network to 20 FRROs and directed that every State capital should have one by 2027. The announcement came on 2 November, and it is the first structural widening of the registration grid in years.
Five offices have been added since 2025: Jaipur, Chandigarh and Guwahati in 2025, and Aizawl and Amravati this year, while Kohima, Agartala and Bhubaneswar have been notified. Nine states still have no office, among them Bihar, Goa, Himachal Pradesh, Jharkhand, Madhya Pradesh, Uttarakhand, Arunachal Pradesh, Manipur and Meghalaya. Until recently several capitals were served from other states, with Jaipur served from Delhi and Guwahati from Kolkata, and four of the eight new or notified offices are in the Northeast. The legal frame is the Immigration and Foreigners Act, 2025, which consolidated four earlier laws on the entry, stay, movement and exit of foreigners into one statute. The Bureau of Immigration performs immigration functions under the Home Ministry, assisted by FRROs authorised by the Centre, and much of the work now moves through the e-FRRO digital portal for visa extensions, registration certificates and exit permits.
For Prelims, remember the numbers and the law: 20 FRROs, all State capitals by 2027, the Immigration and Foreigners Act, 2025 consolidating four laws, the Bureau of Immigration under the Home Ministry, and e-FRRO as the online layer behind the physical offices.
For Mains, the point is last-mile presence for immigration administration: a digital regime still needs a local office where a foreigner can be registered, verified and helped, especially in the Northeast where separate permits are common. The administrative challenge will be staffing, training and data-sharing across the new offices, so that expansion does not become a set of signboards without a common digital regime behind them.
Poland's constitutional tribunal fight becomes a full-blown crisis
GS-2
Poland has plunged into a constitutional crisis over control of its constitutional tribunal, with the ruling bloc led by Prime Minister Donald Tusk and the opposition-backed President Karol Nawrocki at loggerheads over appointments made to the tribunal by each side. Judges to the tribunal are appointed by the lower house of parliament, and the competing appointments have left the institution's authority contested.
The standoff has gone beyond a personnel dispute. Voices across the political spectrum, including in the ruling camp, are calling for a constitutional reset to resolve which appointments are valid and on what terms the tribunal can function.
For Prelims, remember what a constitutional tribunal does: it reviews whether laws and state actions conform to the constitution, making it the guardian of constitutional supremacy in systems that have one. Poland is a member of the European Union, where rule-of-law disputes between Warsaw and Brussels have run for years.
For Mains, the episode is a comparative lesson in judicial independence. When the appointment process itself becomes the prize of partisan competition, the court that is supposed to referee constitutional disputes becomes a party to them. India's own debates about judicial appointments gain perspective from watching how a politicised appointment system can paralyse the very institution meant to check power.
Monsoon Session still not prorogued after 83 days
GS-2
Eighty-three days after the Monsoon Session ended, it has still not been prorogued, the longest such gap on record. The session was adjourned sine die, but the formal act of prorogation, which terminates the session, has not followed.
The distinction matters. Adjournment sine die ends a sitting without naming a day for the next meeting, while prorogation, ordered by the President, formally closes the session. Until a session is prorogued, it technically continues, and the gap between adjournment and prorogation has now stretched beyond any previous instance.
For Prelims, anchor the provision: Article 85 empowers the President to summon each House, to prorogue the Houses, and to dissolve the Lok Sabha, and it requires that not more than six months elapse between the last sitting of one session and the first sitting of the next.
For Mains, the delay raises a question of parliamentary discipline rather than of constitutional crisis. Sessions structure the legislative calendar, the tabling of reports and the government's accountability to the House. When formal closure drifts, it blurs the boundary between sessions and weakens the rhythm through which Parliament is meant to hold the executive to account.
Punjab's Lal Lakir scheme puts property cards in villagers' hands
GS-2
Punjab's Lal Lakir scheme is now distributing property cards to village households, formalising ownership of homes built on village habitation land. Lal Lakir refers to the land within a village's red line, the area set aside for houses and household use rather than cultivation, which historically stayed outside the regular revenue record.
A property card gives the household a documented claim to its home. That matters in practical ways: it can be used to settle boundary disputes, to access bank credit against the property, and to pass the house on within the family with a clear record. The scheme runs on the same idea as the national SVAMITVA programme, which uses drone surveys to map village habitation areas and issue property cards.
For Prelims, note the terms: Lal Lakir literally means the red line drawn around village habitation land in revenue records, and SVAMITVA stands for Survey of Villages Abadi and Mapping with Improvised Technology in Village Areas, launched in 2020.
For Mains, this is land records modernisation reaching the last mile. India's land disputes clog courts and block credit, and the root cause is often not contested law but missing or ambiguous records. Formalising village homes is therefore both a governance reform and an economic one, since clear titles convert dead assets into collateral.
Ukraine and the US to talk in Abu Dhabi on November 10-11
GS-2
The Kremlin has confirmed that Ukraine and the United States will hold talks in Abu Dhabi on November 10 and 11, adding another round to the diplomacy around the war in Ukraine. The choice of venue underlines the mediating role Gulf states have played, hosting contacts between parties that rarely meet directly.
No outcome is guaranteed by the announcement of talks, and the history of the conflict counsels caution about reading a meeting as a breakthrough. But sustained contact matters in itself: it keeps channels open for prisoner exchanges, humanitarian arrangements and, eventually, a framework for ending the fighting.
For Prelims, fix the venue: Abu Dhabi is the capital of the United Arab Emirates, and the Gulf states have repeatedly positioned themselves as venues for negotiation between Russia, Ukraine and Western powers.
For Mains, India's interest in the diplomacy is indirect but real. A prolonged war keeps energy markets volatile, disrupts supply chains and complicates India's balancing act between its partners. Any credible path to de-escalation would ease those pressures, which is why New Delhi has consistently backed dialogue over continued escalation.

RBI eases FEMA reporting for individuals and small exporters
Must knowGS-3
The Reserve Bank of India has eased foreign exchange reporting requirements for service exporters and importers, notifying the changes on November 2 through the Foreign Exchange Management (Export and Import of Goods and Services) (Second Amendment) Regulations, 2026. The amendments take effect retrospectively from October 1, the date the unified FEMA trade framework came into force.
Under the revised rules, a resident individual exporting services will be deemed to have submitted the Export Declaration Form once the required payment information has been given to the authorised dealer bank for crediting the proceeds. The same treatment applies to other exporters where the inward remittance is not more than Rs 10 lakh per bill. On the import side, banks must enter service import details in the monitoring system only for importers other than resident individuals and where the invoice or contract value exceeds Rs 10 lakh.
The central bank had already clarified in October that transactions of a personal nature fall outside the reporting framework, and that reporting on the trade monitoring portals is to be done by banks and authorised dealers, not by individual exporters and importers.
For Prelims, note the framework: the Foreign Exchange Management Act, 1999, governs external payments and trade, authorised dealer banks are the intermediaries through which foreign exchange transactions are routed, and the Rs 10 lakh threshold here applies per bill, not to annual earnings.
For Mains, this is ease of doing business applied to the gig and services economy. Freelancers, tutors, creators and small software exporters earn foreign income in small, frequent bills, and a reporting regime designed for large merchandise trade imposed disproportionate compliance costs on them. The reform keeps monitoring where the money is material, while removing the paperwork that discouraged small exporters from formal channels.
A Rs 2,800-crore critical-minerals processing push is on the agenda
Must knowGS-3
A new capital expenditure scheme of about Rs 2,800 crore for critical minerals is reported to be on the government's agenda, aimed at building domestic processing capacity rather than leaving India dependent on imported refined material. The proposal, as reported, would support processing of minerals such as lithium and nickel that feed electric vehicle batteries and clean-energy technologies.
The push sits within a larger policy stack. The National Critical Mineral Mission, approved in January 2025, carries a government outlay of Rs 16,300 crore through 2030-31, and a Rs 1,500-crore incentive scheme for recycling critical minerals from secondary sources was approved in September 2025. Earlier reports had put a lithium and nickel processing incentive at around Rs 3,000 crore, with a possible capital subsidy for eligible plants.
For Prelims, note the category: critical minerals are those essential to modern industry and vulnerable to supply disruption, and India's official list includes lithium, cobalt, nickel, rare earth elements and graphite, among others. They are inputs for batteries, electronics, defence systems and renewable energy equipment.
For Mains, the binding constraint is not what lies underground but what India can refine. Processing capacity is concentrated in a few countries, which gives suppliers pricing power and leaves buyers exposed to export controls. A capex scheme that builds refineries and processing parks at home would move India up the value chain, but its success will depend on feedstock security, power costs and environmental safeguards at the plants themselves.

Navy orders eight Next Generation Corvettes in a ₹53,866-crore deal
Must knowGS-3
The Defence Ministry signed contracts worth ₹53,866.50 crore on 2 November for eight Next Generation Corvettes for the Indian Navy, placing the order with Garden Reach Shipbuilders and Engineers (GRSE) and Goa Shipyard Limited (GSL). It is the largest recent warship order under the self-reliance push, and the ships are to be designed in-house by the Navy itself.
The work is split between the two defence public sector undertakings, with GRSE building five corvettes at Kolkata and GSL building three at Goa. The Cabinet Committee on Security cleared the projects on 29 October, and the new ships are meant to succeed the Khukri and Kora classes. They will carry advanced missile, weapon and sensor suites for anti-surface and anti-submarine warfare, coastal defence and littoral combat, and the programme is expected to generate about 72 lakh person-days of work in the shipyards and 460 lakh person-days in ancillary industries and MSMEs over ten years.
For Prelims, fix the split and the numbers: ₹53,866.50 crore for eight ships, GRSE with five and GSL with three, both defence public sector undertakings, Cabinet Committee on Security clearance on 29 October, and the Khukri and Kora classes as the predecessors being replaced.
For Mains, the design choice is the point: indigenous design kept in-house, combined with competitive selection between two public shipyards, spreads work across the defence-industrial ecosystem instead of importing a foreign design. The test will be delivery timelines, weapons integration and whether the competitive selection model can be repeated for larger warships.
Next Generation Corvettes: the deal at a glance
- Contract value: ₹53,866.50 crore for eight corvettes
- GRSE share: Five corvettes, built at Kolkata
- GSL share: Three corvettes, built at Goa
- Clearance: Cabinet Committee on Security, 29 October 2026
- Employment: About 72 lakh person-days in shipyards, 460 lakh in ancillary industries and MSMEs
Homi Bhabha's birth anniversary recalls the architect of India's atomic programme
Must knowGS-3
The birth anniversary of Homi Jehangir Bhabha was observed on 30 October, recalling the physicist regarded as the father of India's nuclear programme. His work spanned cosmic rays and quantum theory, including Bhabha scattering and the Bhabha-Heitler cascade theory, and he received the Padma Bhushan in 1954.
Bhabha founded the Tata Institute of Fundamental Research in 1945 with support from the Tata Trusts, played the central role in setting up the Atomic Energy Commission in 1948 as its first chairman, and became the first Secretary of the Department of Atomic Energy in August 1954, placed under the direct charge of the Prime Minister. He led the Atomic Energy Establishment at Trombay, renamed the Bhabha Atomic Research Centre in 1967, a year after his death in the 1966 air crash on Mont Blanc.
For Prelims, keep the sequence straight: Tata Institute of Fundamental Research in 1945, Atomic Energy Commission in 1948, Department of Atomic Energy in 1954, and Bhabha Atomic Research Centre as the 1967 rename of the Trombay establishment. The Padma Bhushan came in 1954, and the department answers directly to the Prime Minister.
For Mains, Bhabha's legacy is institutional design and human capital before hardware: a research institute, a commission and a department under the Prime Minister gave the programme autonomy and continuity, and the training schools produced the cadre for Pokhran and the pressurised heavy water reactor fleet. That design also seeded the three-stage programme, which still frames India's nuclear path from natural uranium to thorium.
Homi Bhabha: the institutions, in order
- 1945: Tata Institute of Fundamental Research founded with Tata Trusts support
- 1948: Atomic Energy Commission set up, Bhabha its first chairman
- 1954: Department of Atomic Energy created, Bhabha first Secretary under the Prime Minister
- 1966: Bhabha dies in the Mont Blanc air crash
- 1967: Trombay establishment renamed Bhabha Atomic Research Centre

Tata Motors and Iveco combine into a 21-billion-euro commercial-vehicle giant
GS-3
Tata Motors and Iveco have combined their global commercial vehicle operations into a single business with revenue of about 21 billion euros, creating one of the world's larger truck and bus makers. The combination brings together an Indian manufacturer with deep emerging-market reach and an Italian commercial vehicle maker with a strong European footprint.
The logic of the deal is scale. Commercial vehicles are moving through an expensive transition to electric and cleaner drivetrains, and development costs for new platforms, batteries and software are easier to carry across a larger production base spread over more markets.
For Prelims, note the geography of the deal: Iveco is an Italian commercial vehicle manufacturer, and the combined business spans the European and Asian markets that matter most for truck demand.
For Mains, the combination is a case study in Indian manufacturing going global by acquisition rather than by export alone. It also raises the familiar questions that follow any large cross-border combination: how quickly the two product lines and supply chains can be integrated, and whether the promised scale translates into competitive pricing and technology for buyers in India.
Southern India has grown wetter over seven decades, IMD study finds
GS-3
Southern India has grown wetter over the past seven decades, according to a study by the India Meteorological Department, while north-west India has become drier and hotter. The peninsula's hot semi-arid zone has nearly halved in extent, with much of it turning into a tropical savannah climate.
The shift is a reminder that climate change does not act uniformly across a subcontinent. A region gaining rainfall faces a different set of risks, from waterlogging and crop disease to changing pest patterns, than a region losing it, where groundwater stress and heat dominate.
For Prelims, place the finding in the classification framework: the hot semi-arid and tropical savannah types come from the Koppen climate classification, which groups climates by temperature and rainfall patterns, and the IMD is the national agency for weather observation and forecasting.
For Mains, the policy implication is regional differentiation. Agricultural advice, crop insurance design, water storage and urban drainage cannot rest on a single national rainfall story when the peninsula and the north-west are moving in opposite directions. Planning that treats the monsoon as one variable will misread both regions.
First International Maize Conference puts the 4F crop in focus at Hyderabad
GS-3
The first International Maize Conference opened at the JD Convention Centre in Hyderabad on the theme M4FS, short for Maize Revolution for Food, Feed, Fodder, Fuel and Sustainability in the Changing World. India's maize output has climbed to about 55 million tonnes, and research and extension have delivered 329 hybrids over the last five years.
The All India Coordinated Research Project on Maize develops cultivars and production and protection technologies across 5 zones with 32 centres, from Srinagar and Kangra in the north to Hyderabad, Coimbatore, Mandya and Dharwad in the peninsular zone. Maize is a C4 grass with wide adaptability, kharif-dominant with a rising rabi share, and its growth is pulled by poultry feed, industrial starch and ethanol blending, which has reshaped its cropping economics.
For Prelims, do not swap the numbers: 5 zones and 32 centres for the coordinated project, 329 hybrids in five years, about 55 million tonnes of output, and the M4FS theme. Maize is a C4 crop grown in both kharif and rabi, not kharif alone.
For Mains, maize shows how feed demand and ethanol blending can change a crop's economics faster than food demand alone. The policy questions are crop diversification, water and input use as area expands, and whether research, extension and processing capacity grow together, so that higher output does not simply become a feed and fuel story at the expense of nutrition and soil health.

World Tsunami Awareness Day 2026: resilience starts with you
Prelims
World Tsunami Awareness Day will be observed on November 5, with the 2026 theme 'Be Tsunami Ready: Resilience Starts With You'. The campaign, led by the United Nations Office for Disaster Risk Reduction, shifts the emphasis from warning technology alone to what individuals and communities do when danger approaches: recognising natural warning signs, moving immediately to high ground or inland, knowing local evacuation routes and taking part in drills.
The day was established by the UN General Assembly in December 2015 through Resolution 70/203, and the date, November 5, honours the Japanese story of Inamura-no-hi, in which a village elder set fire to his rice sheaves in 1854 to warn his community of an approaching tsunami. The 2026 campaign aligns with the Sendai Framework for Disaster Risk Reduction, the Early Warnings for All initiative and UNESCO's Tsunami Ready programme for coastal communities.
For Prelims, note India's own system: the Indian Tsunami Early Warning Centre operates from the Indian National Centre for Ocean Information Services at Hyderabad, and India rebuilt its warning capability after the devastating Indian Ocean tsunami of December 2004.
For Mains, the theme carries a policy lesson. Early warning systems are only as good as the last mile: sirens and SMS alerts save lives only if people know the signs, trust the warning and have a practised route to safety. Community drills, evacuation signage and inclusive planning for children, older people and persons with disabilities are therefore as much a part of disaster infrastructure as sensors and satellites.

Bolivia's El Niño emergency puts Andes geography back on the prelims map
Prelims
The President of Bolivia has declared a national emergency over the effects of El Niño, putting one of South America's most geography-dense countries back in the prelims window. El Niño, the warm phase of the ENSO cycle, shifts Pacific rainfall and routinely brings drought-and-flood swings to the Andean states.
Bolivia is a landlocked state in west-central South America, bordered by Brazil, Paraguay, Argentina, Chile and Peru. Sucre is the constitutional capital and houses the Supreme Court, while La Paz is the administrative capital and hosts the executive and legislature. The Andes run through the country in the Cordillera Occidental and Cordillera Oriental, with the high Altiplano between them, and Lake Titicaca, shared with Peru, is South America's second largest lake after Lake Maracaibo. Bolivia lost its coastline to Chile in the War of the Pacific (1879-84).
For Prelims, do not reverse the capitals: Sucre is constitutional and La Paz is administrative, Lake Titicaca sits on the Peru-Bolivia border and is second after Maracaibo, and the Andes pass through Bolivia, Colombia, Ecuador and Venezuela, not Brazil or Paraguay. Bolivia and Paraguay are the two landlocked states of South America.
For Mains, the emergency is a reminder of landlocked economics and ENSO teleconnections: without a coastline, Bolivia depends on port access through Peru and Chile, and a single Pacific warming event can hit agriculture, water and transport together. Planning for such shocks needs regional data-sharing and resilient infrastructure, not just a declaration after the damage.
