Current Affairs — 20 October 2026

1. India–New Zealand Free Trade Agreement Comes Into Force

Basic Concept

A Free Trade Agreement (FTA) is a treaty between two or more countries that reduces or eliminates tariffs (customs duties) and other trade barriers on goods and, often, services and investment, to encourage mutual trade. India has been negotiating or implementing several bilateral FTAs in recent years (such as the India–UAE CEPA and the India–Australia ECTA) as part of a broader strategy to diversify trade partners beyond traditional blocs, under the overall vision of Atmanirbhar Bharat combined with greater global economic integration.

Core Context

The India–New Zealand Free Trade Agreement, signed on 27 April 2026 in New Delhi, formally came into force on 20 October 2026. Commerce Minister Piyush Goyal confirmed that 100% of India's exports to New Zealand will become duty-free from day one, while New Zealand will remove tariffs of up to 10% on a wide range of Indian exports. Inputs India needs, such as wooden logs, coking coal, and metal scrap, get tariff-free access, benefiting Indian manufacturing and infrastructure sectors.

Latest Developments

• Bilateral merchandise trade between the two countries stood at about USD 1.1 billion in 2025-26, a relatively small base that both sides hope to expand sharply.

• A July 2026 India–New Zealand Strategic Partnership set an aspirational target of doubling bilateral goods and services trade to NZ$7 billion by 2030.

• New Zealand has committed to facilitate USD 20 billion of investment into India over time, spanning sectors like dairy technology, agritech, and renewable energy.

• Sensitive Indian sectors such as dairy, sugar, and edible oils have been kept out of tariff concessions, while New Zealand's sensitive exports like apples, kiwifruit, and Manuka honey get calibrated access through Tariff Rate Quotas, a Minimum Import Price mechanism, and seasonal import windows rather than full, immediate liberalisation.

UPSC Prelims Pointers

• The India–New Zealand FTA came into force on 20 October 2026; it was signed on 27 April 2026.

• The agreement is part of India's growing network of FTAs alongside the India–UAE CEPA and the India–Australia ECTA.

• 'Sensitive sectors' in a trade agreement are products shielded from immediate tariff cuts to protect domestic producers (for India: dairy, sugar, edible oils).

2. India–Canada Trade Mission: 34 Agreements Signed Ahead of the CEPA Deadline

Basic Concept

India and Canada have long discussed a Comprehensive Economic Partnership Agreement (CEPA), a wide-ranging trade pact covering goods, services, and investment, distinct from a narrower FTA. Trade talks between the two countries were paused for several years amid diplomatic strain but have gained fresh momentum recently, with both governments setting a target to conclude CEPA negotiations by the end of 2026.

Core Context

During a large Canadian trade delegation's visit to India, Indian and Canadian businesses and institutions signed 34 agreements and Memoranda of Understanding (MoUs) worth approximately CAD 300 million. The visit builds on a fifth round of CEPA negotiations and reflects a broader attempt by both governments to rebuild economic ties through business-to-business engagement even as the formal treaty is still being negotiated.

Latest Developments

• The Canadian delegation was described as one of the largest trade missions to India in over three decades, signalling the priority both sides are giving to the relationship.

• Both countries aim to conclude CEPA negotiations by December 2026, after which tariff and market-access commitments would need parliamentary/legislative ratification in each country.

• The agreements span sectors like agri-business, clean technology, education, and financial services, reflecting the diversified nature of India–Canada economic engagement beyond traditional trade in goods.

UPSC Prelims Pointers

• CEPA stands for Comprehensive Economic Partnership Agreement.

• The India–Canada trade mission resulted in 34 agreements worth about CAD 300 million.

• Both sides are targeting the conclusion of CEPA talks by the end of 2026.

3. Rubio's Mumbai Visit: The US, India, and the Push to Diversify Oil Imports

Basic Concept

India is the world's third-largest oil consumer and imports over 85% of its crude oil needs, making energy security a core element of its foreign and economic policy. India has in recent years diversified its crude import basket well beyond traditional Gulf suppliers, importing significant volumes from Russia at discounted prices following the Russia-Ukraine conflict, while the US has periodically urged India to recalibrate this basket to align with Western sanctions regimes.

Core Context

US Secretary of State Marco Rubio, during a trilateral meeting involving India and the UAE in Mumbai, pitched Indian purchases of oil from the United States and from Venezuela, including potential supply for Reliance's Jamnagar refinery. The outreach comes amid energy-market disruption linked to the US-Iran standoff and heightened risk in the Strait of Hormuz, a chokepoint through which a large share of the world's oil trade passes.

Latest Developments

• The trilateral format (India–US–UAE) reflects the UAE's growing role as an energy and logistics hub bridging Gulf supply with Indian demand.

• India's crude import basket has recently seen record combined shares from Russia, the UAE, and the US, reflecting active diversification rather than dependence on any single supplier.

• Venezuela, holder of the world's largest proven crude oil reserves, has seen renewed US engagement on energy exports despite years of sanctions.

UPSC Prelims Pointers

• Reliance's Jamnagar refinery, mentioned in this context, is the world's largest single-location oil refining complex.

• India imports more than 85% of its crude oil requirement.

• The Strait of Hormuz is a critical global oil-transit chokepoint between Iran and the Arabian Peninsula.

4. India's Currency Swap Rollover to the Maldives

Basic Concept

A currency swap arrangement allows one country's central bank to exchange its currency for another's, giving the recipient country short-term access to foreign exchange (usually US dollars or another hard currency) to manage balance-of-payments or liquidity pressures without depleting its own reserves. India extends such swap lines to South Asian neighbours partly under the SAARC Currency Swap Framework, coordinated by the Reserve Bank of India, as a tool of regional financial stability and 'Neighbourhood First' diplomacy.

Core Context

India approved the rollover of a ₹3,000 crore currency swap facility for the Maldives, enabling the island nation to continue drawing on the facility to meet short-term liquidity needs. The arrangement, extended on concessional terms, comes as the Maldives continues to manage external debt and foreign exchange reserve pressures.

Latest Developments

• The facility operates under the SAARC Currency Swap Framework, through which India supports regional neighbours facing short-term forex stress.

• India has periodically supported Maldivian financial stability in recent years even as the bilateral relationship has seen political ups and downs, underscoring the 'Neighbourhood First' approach's continuity across diplomatic cycles.

• Currency swaps differ from loans or grants in that they are typically for a fixed term and are meant to be rolled over or repaid rather than being a one-way transfer.

UPSC Prelims Pointers

• India's currency swap rollover to the Maldives is worth ₹3,000 crore.

• The facility operates under the SAARC Currency Swap Framework.

• A currency swap gives a country temporary access to foreign exchange without depleting its own reserves.

5. Ladakh's Draft Governance Plan: Lieutenant Governor to Get Final Legislative Authority

Basic Concept

Ladakh became a Union Territory without a legislature in August 2019, after the reorganisation of the erstwhile state of Jammu and Kashmir. A UT without a legislature, like Ladakh, Chandigarh, or the Andaman & Nicobar Islands, is governed directly by the Union Government through an Administrator (here, the Lieutenant Governor), unlike UTs with a legislature such as Delhi or Puducherry, which have elected assemblies with defined (though limited) law-making powers under Article 239AA (for Delhi) or similar provisions. Since 2019, Ladakhi groups (notably the Leh Apex Body and the Kargil Democratic Alliance) have demanded greater autonomy, citing concerns over land, jobs, and cultural identity, with demands ranging from Sixth Schedule status (special tribal-area protections, as in parts of the North-East) to full statehood.

Core Context

A new draft governance proposal for Ladakh, reportedly under discussion with the Union Government, would give the Lieutenant Governor final authority over laws for the Union Territory. Critics argue this concentrates power in an appointed official rather than elected representatives, weakening local democratic input, even as the Centre has in parallel proposed a special Article 371-type framework and discussed a Hill Council structure for Ladakh.

Latest Developments

• Ladakhi civil society groups have sought Sixth Schedule protection, statehood, and a full legislature as alternatives to the current Administrator-led model.

• The Centre has at various points floated a special Article 371-K type framework (drawing on provisions that give special status to certain states/regions) as a middle path between the status quo and full statehood.

• The debate echoes broader constitutional questions about UT governance seen in Delhi's tussle between the Lieutenant Governor and the elected government, though Ladakh's situation differs since it has no legislature at all.

UPSC Prelims Pointers

• Ladakh became a Union Territory without a legislature in August 2019.

• The Sixth Schedule of the Constitution provides for the administration of certain tribal areas, mainly in the North-East.

• Article 239AA deals with the special provisions for the National Capital Territory of Delhi.

6. Special Intensive Revision of Electoral Rolls: Delhi's Form 6 Backlog Raises Concerns

Basic Concept

The Election Commission of India (ECI) is conducting a Special Intensive Revision (SIR) of electoral rolls in several states and Union Territories, a more thorough, door-to-door verification exercise than the routine annual revision, aimed at removing ineligible entries (such as duplicates or deceased voters) and ensuring accurate enrolment, including of new and left-out eligible voters. Form 6 is the prescribed form under the Registration of Electors Rules, 1960, used by a citizen to apply for first-time enrolment or inclusion in the electoral roll at a new address.

Core Context

Data reviewed during Delhi's SIR shows that only 1,238 of the roughly 4.5 lakh Form 6 applications filed had been processed in the first 42 days of the exercise, raising concerns about whether the stipulated deadline of 30 November 2026 for completing the revision can realistically be met. This builds on an existing debate (flagged in recent days) around the ECI's move toward machine-readable electoral rolls and the broader transparency and audit demands around the SIR process nationally.

Latest Developments

• The slow pace of Form 6 disposal in Delhi has triggered concern that genuinely eligible voters, especially the young and recently relocated, could be left off the rolls if processing isn't accelerated before the deadline.

• SIR exercises have previously drawn political controversy in other states over concerns of arbitrary exclusion, making transparent, time-bound processing a key accountability issue.

• The ECI's parallel move toward machine-readable electoral rolls aims to improve the auditability and portability of voter data, a demand that has grown alongside concerns over the SIR's pace and transparency.

UPSC Prelims Pointers

• Form 6 (under the Registration of Electors Rules, 1960) is used for new voter enrolment or a change of address.

• Delhi's SIR deadline for completion is 30 November 2026.

• The Special Intensive Revision (SIR) is a more rigorous exercise than the routine annual revision of electoral rolls.

7. Religious Conversion and Reservation: Supreme Court Upholds Madras High Court Ruling on Tamil Nadu's Backward Class Order

Basic Concept

Reservation for Socially and Educationally Backward Classes (SEBCs) in India is meant to address historical social disadvantage, not religious identity per se. A long-standing legal question is whether a person who converts from a Scheduled Caste or a backward Hindu community to another religion (commonly Christianity or Islam) can retain caste-based reservation benefits, since Scheduled Caste status under the Constitution (Scheduled Castes) Order, 1950 is generally limited to Hindus, Sikhs, and Buddhists, while backward-class (OBC) status is assessed independently of religion based on social and educational backwardness.

Core Context

The Supreme Court upheld a Madras High Court ruling that Tamil Nadu's 2024 government order, which sought to automatically grant converts to Islam the state's Backward Class Muslim reservation status, could not operate automatically. The Court held that such classification requires objective evidence of continuing social and educational disadvantage after conversion, and it suggested the state undertake an empirical study rather than rely on a blanket administrative order.

Latest Developments

• The ruling reinforces the principle that backward-class status must be based on demonstrated social and educational indicators, not religious identity or community label alone.

• It is distinct from the separate (and more frequently discussed) debate over Scheduled Caste status for Dalit converts to Christianity or Islam, which remains governed by the Constitution (Scheduled Castes) Order, 1950.

• The judgment may prompt Tamil Nadu and other states to commission empirical backwardness studies before issuing similar classification orders in the future.

UPSC Prelims Pointers

• The Constitution (Scheduled Castes) Order, 1950 currently limits SC status to Hindus, Sikhs, and Buddhists.

• OBC/Backward Class status, unlike SC status, is determined by social and educational backwardness rather than a religion-linked list.

• The case involved a 2024 Tamil Nadu government order on Backward Class Muslim status.

8. China's New Export Curbs on Tunnel-Boring and High-Altitude Machinery

Basic Concept

Export controls are restrictions a country places on the sale of certain goods or technologies abroad, often citing national security, and have increasingly become a tool of geo-economic leverage, as seen earlier with China's curbs on rare-earth elements and gallium/germanium exports. Tunnel-boring machines (TBMs) are large, specialised machines used to dig tunnels for metro rail systems, road and rail tunnels, and strategic border infrastructure, a sector where China is a dominant global manufacturer.

Core Context

China announced that, from 18 November 2026, exporters will need licences or registration to export tunnel-boring machines and high-altitude heavy machinery, citing national security considerations. Since India relies substantially on Chinese-made TBMs and heavy equipment for metro projects and for infrastructure in high-altitude border areas (such as Ladakh and Arunachal Pradesh), the move could affect project timelines, especially given pre-existing customs clearance delays for Chinese equipment and components.

Latest Developments

• The curb follows a broader pattern of China using targeted export controls (rare earths, gallium, germanium, and now specialised machinery) as leverage in trade and strategic disputes.

• India's urban metro expansion programmes and Border Roads Organisation projects in high-altitude terrain are among the sectors most exposed to potential delays.

• The move may accelerate Indian efforts to develop domestic or alternative-source capacity for tunnel-boring and high-altitude construction machinery.

UPSC Prelims Pointers

• China's new licensing requirement for TBM and high-altitude machinery exports takes effect from 18 November 2026.

• A Tunnel-Boring Machine (TBM) is used for excavating tunnels for metro, rail, and road projects.

• China has previously used export controls on rare earths and gallium/germanium as strategic leverage.

9. China Exits Sri Lanka's Colombo Port Logistics Venture

Basic Concept

Sri Lanka occupies a strategically important position along major Indian Ocean shipping lanes, making its ports a focus of competing infrastructure interests from India, China, and other powers. China has historically invested heavily in Sri Lankan port infrastructure (most notably Hambantota Port, taken on a 99-year lease after Sri Lanka could not service Chinese loans), while India and other partners have sought a greater role in projects like the Colombo Port's Western/East Container Terminal amid concerns over debt-trap dynamics and strategic access.

Core Context

China Merchants Port Holdings withdrew from a USD 392 million logistics hub joint venture at Colombo Port. This is the second major Chinese exit from a Sri Lankan port-related project in recent years, after Adani Green Energy's 2025 withdrawal from a separate Sri Lankan renewable energy venture. Sri Lanka has indicated it will now pursue the logistics hub through a competitive Public-Private Partnership (PPP) bidding process instead.

Latest Developments

• The exit reflects shifting risk calculations around large Chinese infrastructure investments in Sri Lanka amid the country's ongoing debt restructuring following its 2022 economic crisis.

• A competitive PPP bidding process could open space for Indian, Japanese, or other investors to participate in Colombo's port logistics expansion.

• Port and connectivity infrastructure in Sri Lanka remains strategically significant for India given its proximity and the broader India-China competition for influence in the Indian Ocean Region.

UPSC Prelims Pointers

• China Merchants Port Holdings withdrew from a USD 392 million Colombo Port logistics venture.

• Hambantota Port was leased to China for 99 years after Sri Lanka defaulted on related loans.

• A Public-Private Partnership (PPP) involves collaboration between government and private entities to develop and finance infrastructure.

10. West Asia on Edge: Houthi Attack in Yemen and Mined Tankers in the Strait of Hormuz

Basic Concept

Yemen has been embroiled in a prolonged civil conflict since 2014-15, with the Iran-aligned Houthi movement controlling large parts of the country's north and west against the internationally recognised government. Separately, the Strait of Hormuz, lying between Iran and the Arabian Peninsula, is one of the world's most important oil chokepoints, through which roughly a fifth of global oil consumption passes; it has repeatedly been a flashpoint during periods of tension between Iran and Western powers.

Core Context

A Houthi missile strike on a government military training camp in southern Yemen has seen its reported death toll rise to 73 fighters, among the deadliest single attacks in the conflict in recent months. Separately, Iran's Revolutionary Guards said mines struck and halted three oil tankers in the Strait of Hormuz, an incident consistent with heightened regional tension linked to the broader US-Iran standoff.

Latest Developments

• The rising Houthi attack toll underscores the fragility of ceasefire and de-escalation efforts in Yemen's long-running civil war.

• Mine incidents in the Strait of Hormuz raise global energy security concerns, since any disruption to this chokepoint has outsized effects on oil prices and supply chains, including for India, a major oil importer.

• Both events are unfolding against the backdrop of wider West Asian instability, directly shaping discussions (such as Rubio's Mumbai visit, covered separately) around diversifying India's energy sources.

UPSC Prelims Pointers

• The Strait of Hormuz lies between Iran and the Arabian Peninsula and is a critical global oil-transit chokepoint.

• Houthi forces are an Iran-aligned group controlling significant parts of northern and western Yemen.

• Roughly a fifth of global oil consumption is estimated to transit through the Strait of Hormuz.

11. Global Hunger Index 2026: India Still in the 'Serious' Hunger Category

Basic Concept

The Global Hunger Index (GHI) is an annual report, jointly published by Concern Worldwide and Welthungerhilfe, that ranks countries on hunger and undernutrition using four indicators: undernourishment (insufficient caloric intake), child stunting (low height-for-age, reflecting chronic undernutrition), child wasting (low weight-for-height, reflecting acute undernutrition), and child mortality (deaths of children under five). Countries are classified into categories from 'low' to 'extremely alarming' based on their composite score.

Core Context

In the GHI 2026, released around World Food Day, India ranked 100th among 122 countries with a score of 24.1, placing it in the 'serious' hunger category. While India's child stunting (29.3%) and under-five mortality figures have improved markedly since 2000, child wasting, at 19% in 2026, remains high and has shown little durable improvement over the past two decades, and is flagged by the report as among the worst in South Asia.

Latest Developments

• India's undernourishment rate has fallen from 18.4% in 2000 to 9.8% in 2026, reflecting gains in food availability and welfare schemes.

• Child stunting fell from about 50% in 2000 to 29.3% in 2026, a significant long-term improvement.

• Child wasting, however, stood at 19% in 2026, higher than the 15% recorded in 2012, indicating that acute undernutrition (often linked to immediate food/health shocks) remains a persistent challenge distinct from chronic stunting.

• The government has previously contested GHI methodology, particularly its reliance on a general undernourishment estimate derived from a limited opinion-based survey rather than direct anthropometric measurement for that indicator.

UPSC Prelims Pointers

• The GHI uses four indicators: undernourishment, child stunting, child wasting, and child mortality.

• India's GHI 2026 rank is 100 out of 122 countries, with a score of 24.1 ('serious' category).

• Child wasting reflects acute undernutrition (low weight-for-height); stunting reflects chronic undernutrition (low height-for-age).

12. PLFS September 2026: India's Jobs Data Shows a Largely Stagnant Labour Market

Basic Concept

The Periodic Labour Force Survey (PLFS), conducted by the National Statistical Office (NSO) under the Ministry of Statistics and Programme Implementation (MoSPI), is India's principal source of monthly and annual employment-unemployment data. Key indicators include the Unemployment Rate (UR, share of the labour force without work), the Labour Force Participation Rate (LFPR, share of the working-age population in the labour force, whether employed or seeking work), and the Worker Population Ratio (WPR, share of the population actually employed).

Core Context

The NSO's PLFS bulletin for September 2026 showed the Unemployment Rate holding steady at 5.0%, unchanged from August 2026, while the Labour Force Participation Rate eased marginally to 55.5% from 55.6%. On a year-on-year basis, however, the LFPR was up by about 0.2 percentage points and the UR down by about 0.2 percentage points compared to September 2025, suggesting gradual improvement over a longer horizon even as month-to-month movement stayed flat.

Latest Developments

• Urban women's unemployment rose to 9.2% in September 2026 from 8.9% in August, a trend worth watching given persistently low female workforce participation in urban India.

• Rural men's unemployment also edged up slightly, while urban men's unemployment eased marginally to 6.0% from 6.1%.

• The overall Worker Population Ratio (WPR) was 52.7%, with a notable gap between male WPR (73.6%) and female WPR (32.8%), underlining the continuing gender gap in workforce participation.

UPSC Prelims Pointers

• PLFS is conducted by the National Statistical Office (NSO) under MoSPI.

• India's Unemployment Rate for September 2026 was 5.0%, unchanged month-on-month.

• LFPR = Labour Force Participation Rate; WPR = Worker Population Ratio; UR = Unemployment Rate.

13. Kerala's Vanishing Paddy Fields and a Weakening Conservation Law

Basic Concept

The Kerala Conservation of Paddy Land and Wetland Act, 2008 was enacted to protect the state's shrinking wetlands and paddy fields, which are vital for flood regulation, groundwater recharge, local food security, and biodiversity, by restricting their conversion to non-agricultural use except under tightly defined conditions and government approval. Wetlands and paddy fields also form important carbon sinks and support traditional livelihoods, making their loss both an environmental and a food-security concern.

Core Context

Data shows Kerala's paddy area has fallen by about 80% between 1974-75 and 2024-25. A review highlights that successive amendments and administrative circulars have progressively diluted the 2008 Act's original conservation intent, even without a formal legislative repeal, while the Revenue Department (which also collects regularisation fees for converted land) faces an inherent conflict of interest in enforcing the law it is meant to uphold.

Latest Developments

• Nearly a decade after the Comptroller and Auditor General (CAG) first flagged illegal land conversion and poor restoration enforcement, the underlying problems persist.

• Experts recommend building a comprehensive wetland databank, shifting monitoring away from the Revenue Department to an agency without a financial stake in conversions, restoring the law's original stringent conditions, and ensuring real penalties for violations.

• The case illustrates a broader governance pattern where protective legislation can be effectively weakened through subordinate rule-making and circulars without ever being formally repealed by the legislature.

UPSC Prelims Pointers

• The Kerala Conservation of Paddy Land and Wetland Act was enacted in 2008.

• Kerala's paddy cultivation area has shrunk by roughly 80% since 1974-75.

• The Comptroller and Auditor General (CAG) is India's supreme audit institution, mandated under Article 148 of the Constitution.

14. Boosting Deep-Tech: Government Funds ideaForge's YETI Drone and QNu Labs' Quantum Network

Basic Concept

The Research, Development and Innovation (RDI) Scheme is a Government of India initiative with an outlay of about ₹1 lakh crore, designed to catalyse private-sector investment in deep-tech and strategic sunrise sectors such as artificial intelligence, robotics, space, semiconductors, and advanced manufacturing, areas where private capital alone has historically been reluctant to fund long-gestation, high-risk research. The Technology Development Board (TDB), functioning under the Department of Science and Technology, supports the commercialisation of indigenous technology through financial assistance to industry.

Core Context

The Technology Development Board approved financial assistance of about ₹151 crore in long-term, concessional debt to ideaForge Technology to develop YETI, a heavy-lift autonomous drone platform, marking the first disbursement under the RDI Scheme. Separately, TDB and the Department of Science and Technology signed a ₹150 crore agreement with QNu Labs to advance quantum-secure networking technology, an area critical for safeguarding future communications against the threat quantum computers pose to today's encryption methods.

Latest Developments

• ideaForge's YETI platform aims to significantly expand the payload and range capabilities available to Indian drone users, relevant for both civilian logistics and defence applications.

• QNu Labs' quantum-secure networking work includes Quantum Key Distribution (QKD), a method of securely sharing encryption keys using the principles of quantum mechanics so that any interception attempt is detectable.

• Both disbursements reflect the government's push to reduce reliance on imported critical and dual-use technologies, aligned with Atmanirbhar Bharat in the defence and deep-tech space.

UPSC Prelims Pointers

• The RDI Scheme has a total outlay of about ₹1 lakh crore.

• ideaForge received about ₹151 crore in TDB funding for its YETI heavy-lift drone, the scheme's first disbursement.

• Quantum Key Distribution (QKD) uses quantum mechanics principles to detect interception attempts on encrypted communication.

15. Skyroot–Reflect Orbital Deal: Can Mirror Satellites Bring 'Sunlight at Night'?

Basic Concept

Skyroot Aerospace is a private Indian space-launch company and one of the prominent players in India's growing commercial space sector following the opening up of the space domain to private enterprise under the Indian Space Policy, 2023. Its Vikram series of small launch vehicles is designed to carry small satellites to low Earth orbit (LEO) at competitive cost, positioning India as a hub for affordable commercial launches.

Core Context

Reflect Orbital, a US startup developing satellites fitted with large mirrors to reflect sunlight onto specific spots on Earth after dark, has contracted Skyroot Aerospace for two satellite launches, one on the debuted Vikram-1 (capacity of about 350 kg to LEO) and one on the upgraded Vikram-1U (capacity of about 550 kg to LEO), expected to fly in early 2027. Reflect Orbital already holds US regulatory (FCC) approval for its first mirror satellite and envisions an eventual constellation of tens of thousands of such mirrors.

Latest Developments

• Proposed uses of on-demand nighttime sunlight include extending solar-panel power generation after sunset, aiding search-and-rescue operations, and lighting large outdoor events.

• The deal is commercially significant for India's space sector, showcasing Indian private launch capability being chosen by a foreign space startup rather than only serving domestic or government payloads.

• Large mirror-satellite constellations also raise debated concerns among astronomers about increased night-sky brightness interfering with ground-based astronomical observation.

UPSC Prelims Pointers

• Skyroot Aerospace's Vikram-1 can carry about 350 kg to low Earth orbit (LEO).

• Reflect Orbital's technology aims to beam reflected sunlight to specific locations on Earth after dark using orbital mirrors.

• The Indian Space Policy, 2023 opened up greater private-sector participation in India's space sector.

16. A Fourth Naturally-Occurring Contagious Cancer Discovered — This Time in Catfish

Basic Concept

Most cancers are not infectious; they arise from mutations within an individual's own cells and cannot spread to another individual. However, science has documented a handful of rare exceptions, known as transmissible or contagious cancers, where cancer cells themselves act as an infectious agent that physically passes from one organism to another (examples include the Tasmanian devil facial tumour disease and certain cancers in shellfish such as clams and mussels).

Core Context

Researchers in Vermont, USA identified a transmissible melanoma (a type of skin cancer) in brown bullhead catfish in Lake Memphremagog, marking the fourth documented naturally occurring contagious cancer among animal species. Genetic evidence indicates the cancer cells themselves are the infectious agent, spreading between fish during spawning, when the animals are in close physical contact.

Latest Developments

• A striking feature of this case is that the catfish's immune systems do not reject the foreign cancer cells, a phenomenon scientists hope to study further to understand mechanisms relevant to preventing organ-transplant rejection in humans.

• The three previously known naturally occurring contagious cancers were the Tasmanian devil facial tumour disease and two distinct contagious cancers found among shellfish populations.

• Such discoveries broaden scientific understanding of cancer biology and immune evasion, with potential long-term relevance for oncology and transplant medicine.

UPSC Prelims Pointers

• This is the fourth documented naturally occurring contagious cancer in animals, found in brown bullhead catfish.

• The Tasmanian devil facial tumour disease is a well-known example of a naturally occurring contagious cancer.

• In contagious cancers, the cancer cells themselves (not a virus) act as the infectious agent.

17. Lithium from Seawater: A New Extraction Method by Indian Scientists

Basic Concept

Lithium is a critical mineral central to the clean-energy transition, being a key component of the lithium-ion batteries used in electric vehicles, mobile devices, and grid storage. India currently imports almost all of its lithium requirement, as large, easily mineable domestic lithium reserves (such as those explored in Jammu & Kashmir's Reasi district) are still being assessed, making alternative extraction methods, including from seawater, of strategic interest for reducing import dependence.

Core Context

Indian scientists have developed a new method to extract lithium from seawater, where the metal is present in vast but highly dilute quantities, making conventional extraction economically challenging. While details of the exact technique were not fully specified in initial reports, such innovations typically rely on selective membranes, adsorbent materials, or electrochemical processes designed to selectively capture lithium ions from the complex mixture of salts present in seawater.

Latest Developments

• Seawater is estimated to hold vastly larger total lithium reserves than all known land-based deposits combined, though at concentrations low enough that extraction has traditionally been cost-prohibitive at scale.

• A viable, cost-effective seawater lithium extraction method could meaningfully reduce India's import dependence on countries like Australia, Chile, and China for this critical mineral.

• The development aligns with India's National Critical Mineral Mission, which aims to secure supply chains for minerals essential to clean energy and advanced manufacturing.

UPSC Prelims Pointers

• Lithium is classified as a critical mineral essential for lithium-ion batteries used in EVs and energy storage.

• India currently depends heavily on imports to meet its lithium requirements.

• Seawater holds far larger total lithium reserves than land-based deposits, though at very low (dilute) concentrations.

18. Practice MCQs

Practice MCQs

Q1. Consider the following statements regarding the India–New Zealand Free Trade Agreement, which came into force on 20 October 2026:
1. It was signed in April 2026.
2. Dairy, sugar, and edible oils have been fully opened up to New Zealand imports under the agreement.
3. New Zealand's exports of apples and kiwifruit to India get calibrated (not full immediate) access through Tariff Rate Quotas.
Which of the statements given above is/are correct?
