  • [13th May 2025] The Hindu Op-ed: How is shipping industry tackling emissions?

    PYQ Relevance:

     [UPSC 2022] Discuss global warming and mention its effects on the global climate. Explain the control measures to bring down the level of greenhouse gases which cause global warming, in the light of the Kyoto Protocol, 1997.

    Linkage: The shipping industry’s contribution to GHG emissions (approximately 1 billion metric tonnes annually, about 2.8% of total global emissions) and the IMO’s efforts to reduce these emissions to align with goals like the Paris Agreement. The question’s focus on international climate agreements (Kyoto Protocol) is relevant to the IMO’s regulatory efforts.

     

    Mentor’s Comment: The adoption of the Net Zero Framework, which is based on Market-Based Measure (MBM) by the International Maritime Organization (IMO) to regulate and reduce greenhouse gas (GHG) emissions from international shipping, marking a historic shift in global climate governance. It highlights the geopolitical negotiations, competing national interests, and the struggle to balance environmental effectiveness with economic fairness in formulating a global carbon levy on shipping emissions.

    Today’s editorial talks about regulation of greenhouse gas (GHG) emissions from international shipping.  This topic is useful for GS Paper II (International Relations and Policy Making) and GS Paper III (Environment).

    _

    Let’s learn!

    Why in the News?

    At the Marine Environment Protection Committee (MEPC-83) session of the IMO, a major step was taken by approving a new system to cut shipping emissions.

    What is the International Maritime Organisation (IMO)? 

    The International Maritime Organization (IMO) is a United Nations specialized agency responsible for regulating international shipping, promoting maritime safety, environmental protection, legal matters, and technical cooperation among member states.

    Why is it a landmark step? 

    • First Legally Binding Global Emission Levy: Shipping is the first industry with a mandatory, global emissions levy under the MARPOL treaty—unlike aviation (ICAO) or manufacturing, which follow voluntary or regional norms.
    • Equity Through CBDR-RC: The mechanism incorporates equity—ZNZ fuel users are rewarded, while underperformers bear the financial burden, aligning with developing countries’ interests.
    • Clear, Time-Bound Targets: IMO sets concrete milestones: 40% cut in carbon intensity by 2030, 70% by 2040, and net-zero by 2050—unlike ICAO’s vague goals.

    What were the challenges while taking this step?

    • Resisted by the Oil-Exporting Nations: Countries like Saudi Arabia, which depend heavily on fossil fuel exports, opposed stringent carbon levies, fearing these would harm their economies. They resisted the transition to green fuels, advocating for minimal changes.
    • Developed vs. Developing Countries: Developed nations like the EU supported aggressive emission reductions, while developing countries like China pushed for a market-driven approach to preserve competitiveness and avoid excessive financial burdens.

    How is the shipping industry tackling emissions as per the IMO?

    • Reduction of GHG emissions: The International Maritime Organization (IMO) has implemented measures like the Energy Efficiency Design Index and the Ship Energy Efficiency Management Plan to reduce carbon emissions from ships.
    • Targets for carbon intensity: The IMO has set a goal to reduce carbon intensity by at least 40% by 2030 (compared to 2008 levels) and 70% by 2040, with the ultimate aim of achieving net-zero emissions by 2050.
    • Green technologies and fuel alternatives: The IMO is pushing for cleaner fuels and innovative technologies for emissions reduction, including efforts in alternative fuels such as green hydrogen.

    What is the Net Zero Framework adopted by the IMO?

    The Net Zero Framework is a Market-Based Measure (MBM) to reduce emissions in the shipping industry. It aims to implement a mandatory emissions levy on global shipping to ensure that the sector meets net-zero targets by 2050.

    How would it work? 

    • Emission-Based Levy with Incentives: Ships emitting high greenhouse gases must pay a carbon levy, while those using Zero or Near-Zero (ZNZ) fuels receive financial rewards or credits. Eg: A ship using green hydrogen below the IMO’s emission threshold earns surplus credits, reducing its future levy.
    • Tiered Compliance via GHG Fuel Standard (GFS): Ships are classified based on fuel efficiency and emission levels. Underperformers must purchase remedial units, while high performers gain tradable surplus units. Eg: A vessel exceeding emission targets must buy units from a cleaner ship, creating a carbon market within global shipping.

    What is the limit on carbon emissions?

    • As per IMO reward thresholds:
      • Until 2034: The carbon limit is 19.0 g CO₂e/MJ
      • From 2035 onwards: It tightens to 14.0 g CO₂e/MJ

    How will the Market-Based Measure (MBM) framework impact India’s maritime sector and trade costs by 2030 and 2050?

    • Trade Costs: The MBM framework is likely to increase shipping costs due to carbon pricing and fuel surcharges, making Indian exports less competitive. Eg: Textile and agricultural exports from India to Europe may become costlier by 2030 due to EU’s Emission Trading System (ETS) expansion to maritime transport.
    • Equity Concerns: Uniform carbon levies do not consider developmental disparities, placing a higher burden on countries like India with limited historical emissions. Eg: India has argued at the IMO that MBMs should reflect Common But Differentiated Responsibilities (CBDR), as it is still building infrastructure and trade capacity.
    • Green Shipping Transition: To comply with decarbonization norms by 2050, India must shift to alternative fuels (e.g., green hydrogen, ammonia) and upgrade port infrastructure, requiring massive investments. Eg: Jawaharlal Nehru Port Trust may need to install green bunkering facilities and electrified cargo handling systems.
    • Technological and Financial Gaps: Lack of access to clean technology and climate finance may hinder India’s ability to transition smoothly, increasing dependence on foreign solutions. Eg: Advanced nations may dominate green shipbuilding, while Indian shipyards lag due to lack of R&D support and capital.
    • Opportunity for Green Growth: If supported with international finance and technology transfer, MBMs can stimulate domestic innovation and green job creation in maritime sectors. Eg: India’s “Green Ports” initiative could align with MBM goals and boost employment in clean energy, retrofitting, and logistics.

    Way forward: 

    • Differentiated Levy Design: IMO should adopt a flexible carbon pricing model that reflects Common But Differentiated Responsibilities (CBDR), allowing developing countries like India room to grow while contributing to climate goals. Eg: Tiered levy based on national capacities and emission intensity.
    • Technology Transfer & Climate Finance: Establish dedicated funding mechanisms for green shipping innovation, infrastructure upgrades, and capacity building in developing nations. Eg: An IMO-led global Green Maritime Fund supported by developed countries.

  • India’s rising e-waste, the need to recast its management

    Why in the News?

    India has overhauled its e-waste governance through the E-Waste (Management) Rules, 2022, which came into force on April 1, 2023, replacing the 2016 version. These rules mark a major policy shift to tackle India’s rapidly growing e-waste crisis.

    How Does the New EPR Framework Work?

    • Mandatory Registration: All manufacturers, producers, refurbishers, and recyclers must register with the Central Pollution Control Board (CPCB) through an online portal.
    • EPR Targets: These entities must meet specific collection and recycling targets, as set by the CPCB.
    • Liability for Non-compliance: Failure to meet targets invokes environmental compensation and penalties.

    What is the role of EPR floor pricing in e-waste management?

    • Ensures Fair Returns to Formal Recyclers: EPR floor pricing guarantees minimum compensation for authorized recyclers, making formal recycling economically viable and discouraging unsafe informal practices. Eg: A certified recycler adopting advanced e-waste extraction technologies is assured stable earnings, promoting compliance and expansion.
    • Reduces Informal Sector Dominance: By offsetting the cost advantage of informal recyclers, floor pricing shifts e-waste processing to the formal sector, where health and environmental standards are enforced. Eg: In India, 95% of e-waste is handled informally; floor pricing helps shift this to regulated channels.
    • Boosts Circular Economy and Material Recovery: Stable pricing encourages recyclers to focus on resource recovery—such as copper, gold, and rare metals—rather than mere disposal. Eg: Proper recycling of circuit boards in formal facilities helps recover precious metals worth crores, reducing raw material imports.

    What are the economic and social consequences of poor e-waste management?

    • Economic loss from pollution: Over $10 billion lost annually due to pollution from toxic e-waste processing.
    • Social cost: Informal processing results in $20 billion in social loss, affecting women and children, whose average lifespan is under 27 years.
    • Lost revenue and metals: India forfeits ₹80,000 crore annually in metal value and $20 billion in tax revenue due to untracked, cash-based operations.
    • Health impacts: Open incineration and use of cyanide and sulphuric acid cause air, water, and soil pollution, compounding public health crises.

    How does stable pricing support formal recycling?

    • Ensures Financial Viability for Formal Recyclers: A minimum (floor) price for EPR certificates guarantees fair compensation, encouraging recyclers to invest in safe, modern technologies. Eg: Certified recyclers can recover precious metals like gold and copper efficiently with advanced equipment, making operations economically viable.
    • Discourages Hazardous Informal Practices: Stable pricing removes the informal sector’s cost advantage, shifting recycling away from unsafe, illegal methods. Eg: With assured returns, recyclers prefer compliance over risky open burning and acid-leaching methods that dominate 95% of the sector.
    • Drives Compliance and Investment: Predictable prices create trust in the system, helping producers meet EPR obligations and promoting infrastructure development.

    What are the challenges? 

    • Dominance of the Informal Sector: A large share of e-waste in India is processed by the informal sector using hazardous and unsafe methods like acid baths and open burning. Eg: In Seelampur (Delhi), a major informal e-waste hub, workers dismantle electronics without protection, exposing themselves to toxic substances like lead and mercury.
    • Low Consumer Awareness and Participation: Many consumers are unaware of proper e-waste disposal methods, leading to hoarding, landfilling, or selling to unregulated recyclers. Eg: In cities like Bengaluru and Mumbai, residents often discard electronics with household waste or sell them to local kabadiwalas despite having formal collection centers.

    Way forward: 

    • Strengthen Awareness and Consumer Participation: Promote widespread consumer education on e-waste disposal through campaigns and incentives for responsible recycling, ensuring more e-waste is directed to formal, safe channels.
    • Enhance Infrastructure and Enforcement of EPR: Develop advanced e-waste recycling infrastructure and strictly enforce EPR compliance to ensure producers meet recycling targets and transition e-waste processing to the formal sector.

    Mains PYQ:

    [UPSC 2023] What is the status of digitalization in the Indian economy? Examine the problems faced in this regard and suggest improvements.

    Linkage: India’s growing e-waste problem is linked to its fast digital growth and greater use of electronic gadgets. This issue mainly relates to the economy but also highlights how digitalisation is a key reason behind the rise in e-waste.

  • Explained: Why farmers prefer growing rice and wheat

    Why in the News?

    The combination of assured government support and scientific advancements in breeding technologies has made rice and wheat the most preferred crops among Indian farmers, while other crops lag due to lack of similar incentives and innovations.

    Why do farmers prefer rice and wheat?

    • Assured Procurement at MSP: The government provides near-guaranteed purchases of rice and wheat at Minimum Support Prices (MSP), reducing market risk. Eg: In Punjab, rice area increased from 29.8 lakh hectares in 2015-16 to 32.4 lakh hectares in 2024-25 due to consistent MSP support.
    • Lower Yield Risk Due to Irrigation and Research Support: Rice and wheat are mostly grown under irrigated conditions and benefit from superior public research, leading to more stable yields. Eg: Wheat variety HD-3385, released in 2023, offers 6 tonnes/hectare yield with resistance to rust diseases and adaptability to different sowing times.
    • Continuous Breeding Innovations and Higher Returns: These crops have seen regular improvements through breeding, enhancing productivity, stress tolerance, and input efficiency. Eg: Genetically-edited rice variety Kamala yields up to 9 tonnes/hectare and matures faster, saving water and fertilizer costs.

    What drives yield growth in these crops?

    • Genetic Improvements and Breeding Innovations: Continuous breeding has led to development of high-yielding, stress-resistant varieties. Eg: Wheat variety HD-3385, released in 2023 by ICAR, yields an average of 6 tonnes/hectare with a potential of 7.3 tonnes, and is resistant to all three major rusts (yellow, brown, and black).
    • Improved Agronomic Practices and Technology Adoption: Advanced farming practices like early sowing, use of fertiliser-responsive varieties, and direct seeding have boosted productivity. Eg: Direct-Seeded Rice (DSR) technology eliminates the need for nursery and transplanting, saving water and labour, and supporting yield levels up to 10 tonnes/hectare in some hybrid varieties.
    • Public Research and Extension Support: Rice and wheat receive consistent support from government research institutions, unlike many other crops. Eg: The CRISPR-Cas edited rice variety Kamala, developed by ICAR in 2024, produces 450-500 grains per panicle (vs. 200-250 in parent variety), yields up to 9 tonnes/hectare, matures 15-20 days earlier, and requires less fertiliser and water.

    How has government policy influenced the cropping patterns in states?

    • Minimum Support Price (MSP) and Procurement Assurances: Farmers prefer crops with assured government procurement at MSP, reducing market risk. Eg: In Punjab, rice area increased from 29.8 lakh hectares in 2015-16 to 32.4 lh in 2024-25 due to near-guaranteed MSP procurement, while cotton area declined from 3.4 lh to 1 lh.
    • Skewed Research and Input Support: Rice and wheat have received consistent research and extension support, unlike pulses or oilseeds. Eg: ICAR has developed multiple improved wheat and rice varieties (e.g., HD-3385, Kamala), while no major breakthrough has happened in cotton since Bt cotton (2002-06).
    • Irrigation Infrastructure Bias: Government investment in irrigation has favoured crops like rice and wheat, making them less yield-risk prone. Eg: In Madhya Pradesh, wheat area rose from 59.1 lh to 78.1 lh and rice from 20.2 lh to 38.7 lh, as irrigation expansion supported these water-reliant crops.

    Which innovations improved rice varieties?

    • Semi-Dwarf and High-Yielding Varieties: Introduction of semi-dwarf varieties reduced lodging and increased fertiliser response and yields. Eg: IR-8, released in 1966, was the first semi-dwarf rice variety, yielding 4.5–5 tonnes/hectare in just 130 days, compared to 1–3 tonnes in traditional varieties over 160–180 days.
    • Gene Editing using CRISPR-Cas Technology: Advanced gene-editing allows precision improvements in yield and stress tolerance. Eg: Kamala, a GE mutant of Samba Mahsuri developed by ICAR in 2024, yields up to 9 tonnes/hectare, matures earlier, and has 450–500 grains per panicle (vs. 200–250 in the original).
    • Abiotic Stress Tolerance Breeding: Development of varieties tolerant to drought, salinity, and heat stress for resilience in changing climates. Eg: Pusa DST Rice 1, a GE version of Cottondora Sannalu, with edited DST gene, shows improved tolerance to drought and salt stress, enabling cultivation in marginal soils.

    Way forward: 

    • Diversify MSP and R&D Focus: Extend assured procurement and research support to pulses, oilseeds, and millets to reduce over-reliance on rice and wheat.
    • Promote Sustainable Practices: Encourage water-saving technologies like direct-seeded rice, crop rotation, and climate-resilient varieties to ensure long-term agricultural sustainability.

    Mains PYQ:

    [UPSC 2024] What are the major challenges faced by Indian irrigation system in recent times? State the measures taken by the government for efficient irrigation management.

    Linkage: Farmers prefer rice and wheat partly because of access to irrigation which reduces yield risk. Challenges and management of irrigation systems directly impact this aspect of their decision-making.

  • Species in news: Indian Grey Wolf

  • [12th May 2025] The Hindu Op-ed: A fundamental reset to drive manufacturing growth

    PYQ Relevance:

     [UPSC 2023] Faster economic growth requires increased share of the manufacturing sector in GDP, particularly of MSMEs. Comment on the present policies of the Government in this regard.

    Linkage: The importance of the manufacturing sector for economic growth and asks about government policies concerning it, including MSMEs. This aligns perfectly with the theme of driving manufacturing growth as discussed in the article.

     

    Mentor’s Comment:  Global manufacturing and trade are quickly changing, focusing more on products that use advanced technology and innovation. This shift is being powered by strong research and development (R&D), modern technology, skilled workers, and complex supply chains. Also, the high tariffs recently introduced by the United States are expected to further change how the manufacturing industry works.

    Today’s editorial talks about how global manufacturing and trade are changing because of the use of advanced technology and innovation. This topic is useful for GS Paper II (International Relations and Policy Making) and GS Paper III (Manufacturing Sector).

    _

    Let’s learn!

    Why in the News?

    As global changes are set to reshape the manufacturing industry, it is important to focus on technical education, core engineering skills, and new ideas (innovation).

    What challenges hinder India’s efforts to match global manufacturing standards?

    • Low Manufacturing Productivity: India’s manufacturing sector is far less efficient compared to global benchmarks. Eg: In 2023, India’s productivity stood at $8.9K, while the global average was $32K, and the U.S. reached $159K.
    • Limited R&D Investment: Innovation-driven manufacturing requires substantial R&D support, which remains inadequate in India. Eg: India spends just 0.65% of its GDP on R&D, while China spends 2.4% and South Korea 4.5%.
    • Skills Mismatch and Weak Technical Education: The gap between academic training and industrial skill requirements slows the shift to high-tech manufacturing. Eg: Most engineering institutions focus on theory, grading, and rote learning, with less than 50% emphasis on practical training.
    • Underdeveloped Industrial Infrastructure: India lacks world-class manufacturing ecosystems with integrated supply chains and R&D support. Eg: Unlike China’s fully equipped industrial parks, many Indian parks lack plug-and-play facilities, design labs, and testing centers.
    • Low Per Capita Manufacturing Output: India’s contribution to manufacturing per individual is among the lowest in major economies. Eg: In 2023, India’s per capita value added was $0.32K, while the global average was $2K.

    Why must India reform technical education for innovation-led manufacturing?

    • Lack of Practical Skill Development: Engineering education in India emphasizes theoretical knowledge over hands-on experience. Eg: Less than 50% of curriculum time is dedicated to lab work or industry projects, reducing readiness for real-world manufacturing tasks.
    • Weak Focus on Creativity and Problem-Solving: Entrance exams and academic culture focus on rote learning rather than fostering innovation. Eg: Students are trained to solve predefined problems, but lack the ability to tackle open-ended, real-world challenges in engineering and design.
    • Outdated Laboratory and Workshop Infrastructure: Many technical institutions lack modern facilities to train students in advanced manufacturing techniques. Eg: Few colleges have tool rooms, CNC machines, or 3D printing labs, which are standard in global manufacturing training programs.
    • Disconnect Between Industry Needs and Curriculum: The current syllabus often fails to align with rapidly evolving industrial technologies and skills. Eg: Courses in AI integration, robotics, and IoT in manufacturing are still missing or underdeveloped in most core engineering streams.
    • Limited Industry-Academia Collaboration: Technical education lacks structured partnerships with manufacturing companies for internships, research, and product development. Eg: Unlike Germany’s dual education model, Indian students rarely work on live industry problems during their course of study.

    How do state-specific manufacturing parks boost industrial ecosystems?

    • Accelerate Industrial Setup with Plug-and-Play Infrastructure: Ready-to-use facilities reduce time and cost for new manufacturing units. Eg: Tamil Nadu’s SIPCOT parks offer land, power, and water connections upfront, attracting auto and electronics manufacturers quickly.
    • Encourage Localized Skill Development and Employment: Parks drive local job creation and training programs aligned with industry needs. Eg: Gujarat’s Dholera SIR includes skill centers to train youth for electronics, EV, and robotics industries.
    • Foster Innovation and Prototype Development: Dedicated facilities help companies develop, test, and refine products. Eg: Karnataka’s Aerospace SEZ near Bengaluru hosts R&D labs, testing units, and design centers supporting aerospace startups.
    • Build Industry Clusters and Supply Chains: Concentration of allied industries creates efficient ecosystems with shared logistics and services. Eg: Andhra Pradesh’s Sri City SEZ houses over 180 companies across sectors like consumer goods and automotive, fostering collaboration.
    • Attract Investment Through Tailored State Policies: State-specific incentives aligned with local strengths draw both domestic and foreign investors. Eg: Maharashtra’s Aurangabad Industrial City (AURIC) offers tax benefits and sector-specific infrastructure to attract high-tech industries.

    Way forward: 

    • Revamp Technical Education and Skilling: Align curricula with industry 4.0 needs, strengthen practical training, and build strong industry-academia partnerships to boost innovation-led manufacturing.
    • Strengthen Industrial Ecosystems: Expand world-class infrastructure, ensure faster regulatory clearances, and scale up R&D investment to create globally competitive manufacturing hubs.

  • FTA with UK: How a stitch in time can boost India’s textile sector

    Why in the News?

    On May 6, India and the UK signed an important Free Trade Agreement (FTA), which was called a historic achievement by Prime Minister Narendra Modi. The FTA creates new opportunities for the textile sector, which now needs to match global styles and standards

    What are the key benefits of the India-UK Free Trade Agreement (FTA)?

    Benefit Description Eg
    1. Enhanced Market Access India gains zero-duty access to UK markets for industrial and agricultural goods; UK exporters get reduced tariffs in India. Indian processed foods earlier faced 10–12% tariffs — now duty-free in the UK. Tariffs on British whiskey reduced from 150% to 40% over 10 years.
    2. Boost to Key Domestic Sectors Labour-intensive Indian sectors like textiles, apparel, toys, and footwear benefit; UK gains in automobiles and spirits. Indian apparel now gets zero-tariff access to UK.

    Tariffs on British cars slashed from 100% to 10%.
    3. Job Creation & Economic Growth Trade expansion leads to employment generation and investment in both countries. India’s textile sector, employing 45+ million people, can boost jobs through increased exports.
    4. Diversification of Trade Partners India reduces dependency on US/EU; UK diversifies beyond EU post-Brexit. India currently holds just 1.8% share in UK imports — FTA targets major increase.
    5. Foundation for Future FTAs Sets a model for India’s trade negotiations with other major economies like the EU and US. Learnings from tariff cuts and ESG compliance can aid future deals with EU/US.

    How can India improve its Textiles and Apparel sector to capitalize on the FTA with the UK?

    • Strengthen the Value Chain and Infrastructure: India must address its fragmented and geographically dispersed T&A value chain. Fast-tracking the operationalization of PM MITRA parks can create integrated textile hubs, reduce logistics costs, and improve delivery timelines. Eg: Bangladesh delivers apparel orders in 50 days compared to India’s 63 days — a more integrated value chain can help India match or exceed this efficiency.
    • Promote Manmade Fibre (MMF) Production: India needs to resolve the inverted GST structure and ease quality norms to boost MMF-based products, which dominate global demand for technical textiles, athleisure, and activewear. Eg: MMF garments are taxed higher at the input stage than at the finished product level, making Indian exports less competitive globally.
    • Focus on Compliance, Design, and Market Relevance: Indian exporters must align with global fashion trends and strengthen ESG (Environmental, Social, Governance) compliance, especially in anticipation of EU and UK sustainability regulations. Eg: The EU’s Corporate Sustainability Due Diligence Directive (CSDDD) will require traceable, ethical supply chains by 2029 — Indian exporters must prepare accordingly.

    Why is the operationalisation of PM MITRA parks important for India’s textile industry?

    • Integrated Value Chain and Reduced Costs: PM MITRA parks aim to bring together the entire textile value chain — from spinning, weaving, processing to garmenting — in one location, reducing logistics costs, delays, and inefficiencies. Eg: Currently, cotton is grown in Gujarat, yarn spun in Tamil Nadu, and garments stitched elsewhere, leading to high costs and long lead times. An integrated park would streamline this process.
    • Boost Export Competitiveness: These parks can help scale up production, attract investment, and improve quality standards for global markets like the UK, where India now enjoys zero-duty access under the FTA. Eg: By focusing PM MITRA parks in export-oriented regions like Navsari (Gujarat) and Virudhunagar (Tamil Nadu), India can cater more efficiently to UK and EU demand.

    Where does India lag behind in terms of manmade fibre (MMF) production compared to global competitors?

    • Inverted GST Duty Structure: The GST on raw materials (like MMF yarn at 12%) is higher than on finished products (5%), leading to increased production costs and reduced global competitiveness. Eg: Indian MMF garments are costlier compared to those from Vietnam or Bangladesh, where tax structures are more balanced.
    • Restrictive Quality Norms and Compliance Issues: Outdated or complex quality standards limit innovation and access to high-performance MMF products demanded in global markets. Eg: Indian firms struggle to meet the quality requirements for technical textiles used in athleisure and activewear segments.
    • Lack of Investment in High-End Functional Fabrics: India has limited capacity for producing value-added MMF fabrics such as moisture-wicking, stretchable or anti-bacterial textiles, unlike China or South Korea. Eg: While China leads in exporting performance-based textiles, India still focuses on basic polyester products.

    Way forward: 

    • Reform Tax Structure & Boost Incentives: Rationalize the GST structure to eliminate the inverted duty issue and offer production-linked incentives (PLI) for MMF textiles to enhance global competitiveness.
    • Invest in R&D and Modern Manufacturing: Encourage investment in high-performance MMF fabric production, innovation, and compliance infrastructure to meet international standards in technical textiles and sustainability.

    Mains PYQ:

    [UPSC 2017] Account for the failure of the manufacturing sector in achieving the goal of labor-intensive exports. Suggest measures for more labor-intensive rather than capital – intensive exports.

    Linkage: Textiles and Apparel (T&A) sector as a labour-intensive sector that employs over 45 million people and can benefit significantly from the FTA by gaining access to high-end markets. This question directly asks about promoting labour-intensive exports, aligning perfectly with the potential benefits highlighted for the T&A sector through the FTA.

  • Gold’s Cosmic Origins from Magnetar Flares

    Why in the News?

    A new study by Columbia University, suggests that the universe may have an alternate mechanism for producing gold — not just in neutron star collisions, as previously believed, but also in magnetar flares.

    Gold's Cosmic Origins from Magnetar Flares

    What are Magnetars?

    • Magnetars are a rare type of neutron star with immensely strong magnetic fields, among the most powerful in the universe.
    • They are formed when a massive star collapses during a supernova, leaving a highly dense stellar core.
    • Due to magnetic instability, magnetars sometimes release intense flares of X-rays and gamma rays.
    • These flares can be millions of times stronger than typical solar flares.
    • A magnetar’s magnetic field is estimated to be about a thousand times stronger than that of ordinary neutron stars.

    r-Process in a Magnetar Flare:

    • The r-process (rapid neutron-capture process) forms heavy elements like gold, platinum, and uranium by rapidly attaching neutrons to atomic nuclei.
    • It was earlier believed to occur mainly in neutron star mergers.
    • In a 2024 study, scientists analysed a 2004 magnetar flare followed by delayed gamma-ray emissions, recorded by NASA’s Compton Gamma Ray Observatory.
    • The radiation patterns matched those of radioactive decay from r-process elements, suggesting neutron-rich nuclei were produced.
    • Around 1.9 septillion kilograms of matter was ejected at near-light speeds, marking the first direct evidence of r-process nucleosynthesis in a magnetar flare.

    Implications for Gold Formation:

    • The study shows that magnetar flares may also produce gold and other heavy elements, not just neutron star collisions.
    • This implies such elements could have formed earlier in the universe than previously believed.
    • The findings broaden our understanding of the origins of chemical elements in space.
    • It confirms that multiple astrophysical events contribute to the formation of heavy elements.
    • It also offers a new perspective on cosmic gamma-ray bursts and ancient stellar compositions.

  • Scientists create first ‘Pangenome’ of Asian Rice

    Why in the News?

    Chinese researchers has developed a first-of-its-kind rice pangenome by integrating genetic data from 144 wild and cultivated rice varieties from Asia (similar to the Human Genome Project).

    About the Rice Pangenome:

    • A pangenome includes both the core genes shared by all members of a species and the unique genes found in specific varieties, offering a complete view of genetic diversity.
    • The rice pangenome was built using data from 144 wild and cultivated rice varieties across Asia, making it the first comprehensive genomic resource for rice.
    • Researchers led the project from the Chinese Academy of Sciences to explore rice evolution and domestication.
    • Researchers used PacBio HiFi sequencing and advanced computational tools to detect variations, uncovering 3.87 billion base pairs of genetic material previously missing from the standard rice genome.

    Key Findings:

    • The study identified 69,531 genes, including 28,907 core genes common to all varieties and 13,728 genes unique to wild rice.
    • About 20% of all genes were exclusive to wild rice, offering potential for trait improvement in cultivated varieties.
    • The study confirmed that all Asian cultivated rice (Oryza sativa L.) originated from Or-IIIa, a subgroup of Oryza rufipogon.
    • Japonica rice was first domesticated in China, while indica rice arose later via hybridization as japonica spread across Asia.
    • Wild-specific genes were linked to environmental adaptation, phenotypic flexibility, and regenerative traits, offering insights for future crop resilience.
    • Bridging the genetic gap between wild and cultivated rice could lead to climate-resilient and high-yield varieties.

    India’s Contribution:

    • Rice is India’s staple food and the main monsoon crop, grown from June to September.
    • In 2024–25, India produced a record 220 million tonnes of rice over 51,000 hectares, with an average yield of 4.2 tonnes per hectare.
    • The Indian Council of Agricultural Research (ICAR) has developed two genome-edited rice varieties — Samba Mahsuri and MTU 1010 — known for higher yields and drought resistance; these are currently under testing.
    [UPSC 2001] Assertion (A): Scientists can cut apart and paste together DNA molecules at will, regardless of the source of the molecules. Reason (R): DNA fragments can be manipulated using restriction endonucleases and DNA ligases.

    Options: (a) Both A and R are individually true and R is the correct explanation of A * (b) Both A and R are individually true but R is NOT a correct explanation of A (c) A is true but R is false (d) A is fasle but R is true

     

  • BrahMos: the ‘Fire and Forget’ Stealthy Cruise Missile

    Why in the News?

    The BrahMos supersonic cruise missile has garnered global attention as it was reportedly used for the first time in a combat scenario during Operation Sindoor.

    About the BrahMos Missile:

    • BrahMos is a supersonic cruise missile jointly developed by India and Russia through BrahMos Aerospace.
    • The name is derived from the Brahmaputra River (India) and the Moskva River (Russia).
    • It is one of the world’s fastest cruise missiles, reaching speeds up to Mach 3.
    • It was first successfully tested on June 12, 2001, from Chandipur, Odisha.
    • It is a ‘fire and forget’ missile, requiring no further guidance after launch.
    • It can be launched from land, sea, air, and submarine platforms.
    • It has been inducted into the Indian Navy (2005), Army (2007), and Air Force (2017).
    • Key Features:
      • Classified as a stand-off weapon, it can be launched from a safe distance, avoiding enemy defences.
      • The original range was 290 km, now extended to 350–400 km, with future variants targeting 800 km and hypersonic speeds (Mach 5).
      • It offers high accuracy, extended seeker range, and 9 times more kinetic energy than subsonic missiles.
