    _

    Let’s learn!

    Why in the News?

    India is now the world’s fourth-largest economy, moving ahead of Japan, with its GDP reaching $4.3 trillion in 2025. This major success happened because of important changes in the economy and energy sector.

    What are the key components of India’s energy strategy?

    • Four-pronged approach: a) Diversification of energy sources and suppliers, b) Expansion of domestic production, c) Transition to renewables, d) Ensuring affordability for citizens
    • Structural transformation: Significant reforms in both upstream and downstream sectors, including new revenue-sharing models, pricing reforms, and logistics integration.
    • Digital mapping & infrastructure: PM Gati Shakti digitally mapped over 1 lakh energy assets, integrated with the National Master Plan for real-time visibility and route optimization.

    Why is energy security considered equivalent to development security for India?

    • Rapidly Growing Energy Demand: With India projected to account for 25% of global energy demand growth by 2047, uninterrupted energy supply is essential to fuel economic growth, industrial output, and urban development. Eg: India’s rise to the 4th-largest oil consumer shows its energy needs are deeply tied to its global economic standing.
    • Foundation for Self-Reliance and Sovereignty: Ensuring access to affordable and sustainable energy strengthens national resilience and reduces geopolitical vulnerabilities. Eg: Ethanol blending (19.7% in 2025) and expanding biofuels have saved ₹1.26 lakh crore in foreign exchange, enhancing energy independence.
    • Social Stability and Equitable Access: Affordable and stable energy supply supports welfare schemes and shields vulnerable populations from price shocks. Eg: Under PM Ujjwala Yojana, LPG cylinder prices for beneficiaries remain at ₹553 despite a global 58% rise, ensuring energy access for the poor.

    How has India expanded its domestic oil and gas exploration acreage from 2021 to 2025?

    • Doubling Exploration Acreage: India increased its exploration area from 8% in 2021 to 16% in 2025, aiming to cover 1 million sq km by 2030 to unlock vast hydrocarbon resources. Eg: This expansion includes frontier basins like the Andamans and the Mahanadi.
    • Landmark Policy Reforms: Reforms such as reducing ‘No-Go’ zones by 99% and streamlining licensing through the Open Acreage Licensing Policy (OALP) rounds have facilitated easier access for exploration. Eg: The OALP rounds attract new investors by offering simplified licensing.
    • Attractive Pricing and Revenue Sharing: New pricing mechanisms link gas prices to 10% of the Indian crude basket with a 20% premium for new wells, and revenue-sharing contracts allow shared infrastructure, boosting investment incentives. Eg: These incentives encourage development of new gas wells and city gas networks.

    Which renewable energy initiatives have contributed significantly to India’s green energy transition?

    • Ethanol Blending in Petrol: Ethanol blending increased from 1.5% in 2013 to 19.7% in 2025, expanding the ethanol supply from 38 crore litres to 484 crore litres, reducing emissions and saving foreign exchange. Eg: This has saved ₹1.26 lakh crore in foreign exchange and reduced 643 lakh MT of emissions.
    • Compressed Biogas (CBG) through SATAT Initiative: The SATAT program has commissioned over 100 CBG plants and targets a 5% CBG blending mandate by 2028, promoting circular and affordable bioenergy. Eg: Central support for biomass procurement and CBG pipeline connectivity accelerates adoption.
    • Green Hydrogen Production: India has produced 8.62 lakh tonnes of green hydrogen and awarded 3,000 MW electrolyser tenders, with public sector units leading large-scale hydrogen projects. Eg: Indian Oil Corporation’s 10 KTPA green hydrogen tender for the Panipat refinery.

    What are the challenges? 

    • Infrastructure and Technology Gaps: Limited infrastructure for large-scale production, storage, and distribution of renewables like green hydrogen and biofuels slows down adoption. Eg: Need for expanded electrolyser manufacturing capacity to meet tender targets.
    • Feedstock Availability and Supply Chain Issues: Securing consistent and diversified feedstock for biofuels like ethanol and CBG is challenging due to agricultural dependencies and regional disparities. Eg: Ensuring steady supply of molasses, maize, and biomass for ethanol and CBG production.
    • High Initial Costs and Financing Constraints: Capital-intensive nature of renewable projects and lack of affordable financing options can hinder MSMEs and smaller players from scaling up. Eg: Limited access to credit for startups working on cutting-edge green hydrogen technologies.

    Way forward: 

    • Boost Infrastructure and Technology: Invest in large-scale renewable production, storage, and distribution facilities—especially for green hydrogen and biofuels—and expand domestic manufacturing of key technologies like electrolysers.
    • Enhance Feedstock Supply and Financing: Develop diversified, reliable feedstock supply chains for biofuels, and create affordable financing schemes to support MSMEs and startups in scaling clean energy innovations.

  • Building-Integrated Photovoltaics: converting buildings into solar assets 

    Why in the News?

    India’s rooftop solar (RTS) capacity has gone beyond 17 GW, showing good progress in using clean energy in cities. But in crowded urban areas, there isn’t enough space for more rooftop solar panels.

    What is Building-Integrated Photovoltaics (BIPV)?

    BIPV refers to the integration of photovoltaic materials directly into the building envelope (e.g., façades, roofs, windows). It serves both as a building material and a solar power generator. Eg: Façades, curtain walls, glass windows, skylights, tiles, railings, balconies, canopies, atriums, and shading devices.

    How does it differ from traditional rooftop solar systems?

    Traditional Rooftop Solar (RTS) Building-Integrated Photovoltaics (BIPV)
    Installation Added onto rooftops Embedded into building structure
    Space Use Limited to rooftop area Uses entire building envelope (walls, windows etc.)
    Aesthetic Usually visible, can affect aesthetics Customisable, aesthetically integrated
    Function Only generates electricity Generates electricity + serves as a building material
    Retrofitting Often retrofitted Typically integrated during design/build phase

    Why is BIPV particularly important for densely populated urban areas in India?

    • Limited Rooftop Space in High-Rises: In densely populated cities, tall buildings with small rooftops cannot accommodate large rooftop solar (RTS) systems. Eg: A 16-storey building with a 4,000 sq. ft rooftop can install only a 40 kWp RTS system, but its south-facing façade can support 150 kWp BIPV panels.
    • Efficient Use of Building Surfaces: BIPV allows power generation from vertical and horizontal surfaces like façades, windows, and balconies, thus using more surface area. Eg: Façade areas of buildings are often 3–4 times larger than rooftop areas, offering greater solar potential.
    • Supports Sustainable Urban Growth: With India’s urban population projected to reach 850 million by 2051, BIPV enables renewable energy adoption in future infrastructure. Eg: Integration of BIPV in new public infrastructure (e.g., metro stations, airports) can reduce carbon footprint.
    • Energy Access for Non-Rooftop Households: Residents in multi-storey apartments without rooftop access can still benefit from solar energy via BIPV on balconies, railings, or windows. Eg: In Germany, 15 lakh households use balcony solar panels, reducing electricity bills by up to 30%.
    • Aesthetic and Space-Neutral Design: BIPVs blend into building designs without occupying extra space or affecting aesthetics, which is ideal for space-constrained urban settings. Eg: The Renewable Energy Museum in Kolkata has a solar-powered dome with over 2,000 integrated panels, combining function with form.

    What challenges are limiting the adoption of BIPVs in India?

    • High Initial Costs: BIPV systems are more expensive than traditional rooftop solar due to integration with building materials and use of advanced technology.
    • Policy and Regulatory Gaps: Lack of clear policies, mandates, and incentives specific to BIPV hinders its integration into mainstream construction practices. Eg: Unlike Europe’s Energy Performance of Buildings Directive, India’s National Building Code does not yet mandate or promote BIPV use.
    • Low Awareness and Technical Capacity: Architects, builders, and homeowners are often unaware of BIPV’s benefits or how to incorporate it effectively in design.
    • Dependence on Imports and Limited Domestic Manufacturing: India relies heavily on imported BIPV components, increasing costs and reducing supply reliability. Eg: Specialised BIPV glass panels or semi-transparent modules are often imported from China or Europe due to lack of local alternatives.
    • Absence of Standardisation and Performance Guidelines: There are no clear standards, benchmarks, or guidelines for BIPV performance, quality, and installation, causing hesitation among developers. Eg: Without defined safety and efficiency norms, urban local bodies may delay approvals or avoid BIPV in building plans.

    What measures can India take to scale up the uptake of BIPVs effectively? (Way forward)

    • Introduce Targeted Policy Incentives and Subsidies: India should extend solar subsidy schemes to specifically support BIPV adoption, especially in space-constrained urban areas. Eg: Under the PM Surya Ghar Muft Bijli Yojana (2024), BIPV was included with subsidies up to ₹78,000 for a 3-kW residential system. Similar support is needed for commercial and industrial sectors.
    • Embed BIPV in Building and Energy Codes: Integrating BIPV requirements into the National Building Code, Energy Conservation Building Code, and Eco Niwas Samhita can make its use more widespread and standardized. Eg: Europe’s Energy Performance of Buildings Directive mandates solar use in new constructions and promotes BIPV with clear regulations—India can adopt a similar model.
    • Promote Domestic Manufacturing and Demonstration Projects: Boosting indigenous production through PLI schemes, along with pilot projects in public infrastructure (e.g., schools, airports), can improve visibility and reduce costs. Eg: The CtrlS Datacenters in Navi Mumbai and Kolkata’s Renewable Energy Museum show how BIPV can be scaled in real-world infrastructure.

    Mains PYQ:

    [UPSC 2020] India has immense potential of solar energy though there are regional variations in its development. Elaborate.

    Linkage: Building-Integrated Photovoltaics (BIPV) is a key solution for boosting solar adoption, especially in densely populated urban areas where traditional rooftop solar (RTS) is constrained by limited shadow-free space. BIPV transforms entire buildings into power generators by integrating solar elements directly into architectural elements, using available surfaces more efficiently and contributing significantly to India’s solar capacity goals.

  • IISc develops Nanozyme to prevent Abnormal Blood Clotting

    Why in the News?

    Researchers at the Indian Institute of Science (IISc) have created an artificial metal-based nanozyme that can help prevent dangerous blood clotting, especially in conditions like pulmonary thromboembolism (PTE) and COVID-19.

    What is Blood Clotting?

    • About: When we get a cut or injury, our body quickly stops the bleeding by forming a blood clot. This is done by special blood cells called platelets that stick together and seal the wound.
    • Control mechanism: This natural process is called blood clotting or haemostasis and is controlled by certain chemicals in our body like collagen and thrombin.
    • Post covid issues: But in some illnesses like pulmonary thromboembolism (PTE) or COVID-19, the body sends too many signals to make clots, even when there is no injury.
    • Oxidative Stress: This creates a problem called oxidative stress, where harmful molecules called Reactive Oxygen Species (ROS) build up in the blood. These ROS molecules over-activate the platelets, causing them to make too many clots inside blood vessels.
    • Hazards: This can block blood flow, leading to serious health issues like heart attacks, strokes, or lung problems. This condition is called thrombosis, and it can be life-threatening.

    Vanadium-Based Nanozyme and Its Features:

    • Purpose and Design: Scientists at IISc developed vanadium-based nanozymes to mimic natural antioxidant enzymes that reduce ROS levels.
    • How they work: The nanozymes control oxidative stress by copying glutathione peroxidase, an enzyme that removes ROS and protects platelets.
    • Optimal Structure: Spherical-shaped vanadium pentoxide (V₂O₅) nanozymes were found to be the most effective.
    • Test Results in Mice: These nanozymes reduced blood clots and improved survival in PTE-affected mice with no toxicity signs over five days.
    • Next Steps: Scientists plan to test the nanozyme in ischemic stroke and are optimistic about human clinical trials after promising lab results with human platelets.
    [UPSC 2015] With reference to the use of nano-technology in health sector, consider the following statements:

    1. Targeted drug delivery is made possible by nanotechnology.

    2. Nanotechnology can largely contribute to gene therapy.

    Which of the statements given above is/are correct?

    Options: (a) 1 only  (b) 2 only (c) Both 1 and 2* (d) Neither 1 nor 2

     

  • Thermophilic Bacteria in Rajgir Hot Spring could help fight Deadly Infections

    Why in the News?

    Researchers from the Vellore Institute of Technology (VIT) have discovered antibiotic-producing bacteria in the Rajgir hot spring in Nalanda, Bihar.

    What are Thermophilic Bacteria?

    • About: Thermophilic bacteria, or thermophiles (meaning “heat lovers”), are microorganisms that thrive in high-temperature environments ranging from 45°C to 70°C.
    • Adaptation: These temperatures can cause third-degree burns in humans, but thermophiles are biologically adapted to survive and grow in such conditions.
    • Habitats: They are commonly found in hot springs, deep-sea hydrothermal vents, and compost piles, which are mineral-rich and have low microbial competition.
    • Advantages: Some thermophiles produce potent antibiotics to outcompete other microbes and dominate their niche.
    • Global Example: Thermophiles from hot springs in Saudi Arabia have shown antibacterial activity against gram-positive pathogens.

    Key Findings from India:

    • Sampling Challenge: Samples were collected from water and soil at 43°C–45°C, making fieldwork difficult.
    • Microbial Analysis: In the sample, Actinobacteria made up 40–43% of the microbial population, double the typical amount in hot springs.
    • Significance: Actinobacteria are well known for producing key antibiotics like streptomycin and tetracycline.
    • AMR Context: The findings are crucial in the fight against antimicrobial resistance (AMR), which could cost $1 trillion globally by 2050, according to the WHO.
    • Antibiotic Potential:
      • Lab Testing: Seven Actinobacteria strains were found to inhibit pathogens such as E. coli, Salmonella, Klebsiella, Pseudomonas, and Staphylococcus aureus.
      • Compound Discovery: Scientists identified diethyl phthalate using GC-MS, which showed effectiveness against Listeria monocytogenes, a deadly foodborne pathogen.
      • Future Scope: The compound has potential for antibiotic development, but not all thermophiles produce antibiotics, so screening is essential.
    • Uses:
      • Industrial Use: The enzyme Taq polymerase, used in PCR tests (including during COVID-19), is derived from a thermophile called Thermus aquaticus.
      • Agricultural Use: A 2018 BHU study showed thermophiles from Chumathang hot springs (Leh) promote plant growth, revealing wider industrial and ecological value.
    [UPSC 2023] Consider the following statements:

    1. Some microorganisms can grow in environments with temperature above the boiling point of water.

    2. Some microorganisms can grow in environments with temperature below the freezing point of water.

    3. Some microorganisms can grow in highly acidic environment with a pH below 3. How many of the above statements are correct?

    Options: (a) Only one (b) Only two (c) Only three* (d) All four

     

  • Expert Committee recommends ending mandatory Flue Gas Desulphurisation (FGD) 

    Why in the News?

    A high-powered committee chaired by Principal Scientific Advisor (PSA) Ajay Sood has proposed that India should discontinue the mandatory use of Flue Gas Desulphurisation (FGD) units in most coal-fired Thermal Power Plants (TPPs).

    Why mandatory FGDs are opposed?

    • Low SO₂ Levels: India’s SO₂ levels (10–20 µg/m³) are already below the permissible limit of 80 µg/m³.
    • Low Sulphur Coal: Indian coal naturally has low sulphur content.
    • Minimal Impact: Studies show no major air quality difference between plants with and without FGDs.
    • Limited PM Reduction: FGDs have minimal effect on particulate matter levels.
    • Environmental Trade-Offs:
      • CO₂ Increase: Installing FGDs would add 69 million tonnes of CO₂ emissions (2025–2030).
      • SO₂ Reduction: Emissions would fall by 17 million tonnes, but the climate cost outweighs the benefit.

    About Flue Gas Desulphurisation (FGD):

    • Purpose: FGD is a technology used to remove sulphur dioxide (SO₂) from flue gases produced by burning coal and oil, especially in thermal power plants.
    • Environmental Benefit: It helps prevent acid rain, which harms crops, buildings, soils, and aquatic ecosystems.
    • Chemicals Used: Common absorbents include limestone (CaCO₃), lime (CaO), and ammonia (NH₃).
    • Types of Systems:
      1. Dry Sorbent Injection: Cost-effective, but less efficient.
      2. Wet Limestone-Based: Effective and used in large plants, produces gypsum.
      3. Seawater-Based: Uses alkaline seawater, ideal for coastal areas.

    FGD Mandate in India:

    • Current Status: FGD units are being installed in 537 coal-based thermal power units, but 92% of India’s 600 plants still lack them.
    • Committee Recommendation: An expert panel advised exempting 80% of plants from FGD requirements due to feasibility issues.
    • Implementation Barriers: Limited vendors available; High costs and risk of increased electricity tariffs.
    [UPSC 2023] Consider the following:

    1. Carbon monoxide 2. Nitrogen oxide 3. Ozone 4. Sulphur dioxide Excess of which of the above in the environment is/are cause(s) of acid rain?

    Options: (a) 1, 2 and 3 (b) 2 and 4 only* (c) 4 only (d) 1, 3 and 4

     

  • PM to launch Aravalli Green Wall Project

    Why in the News?

    On June 5, World Environment Day, Prime Minister Narendra Modi is expected to launch the Aravalli Green Wall Project.

  • ​Monsoon woes: On the southwest monsoon and the northeast

    Why in the News?

    In 2025, the Southwest Monsoon, which plays a vital role in India’s farming economy, brought heavy and destructive rains. Instead of simply starting the farming season, it has caused widespread damage across the northeastern states.

    Why is the northeastern region particularly vulnerable to monsoon-related disasters?

    • Geographical Terrain and River Systems: The Northeast has a complex topography of steep hills and fast-flowing rivers like the Brahmaputra and Barak. These rivers often overflow during monsoon, causing floods and erosion. Eg: In Assam, over 10 major rivers flowed above danger level in June 2025, affecting over 3 lakh people across 19 districts.
    • High and Prolonged Rainfall: The region receives one of the highest average monsoon rainfalls in India, making even a “below normal” monsoondestructive. Eg: Despite IMD predicting lower-than-normal rainfall, Assam, Tripura, and Sikkim faced flash floods and landslidesin May–June 2025.
    • Dual Monsoon Exposure and Fragile Ecology: The region experiences both the southwest monsoon (June–September) and a retreating monsoon (October–December), increasing disaster exposure. The fragile ecology, including deforestation and slope instability, worsens risks. Eg: In North Sikkim, landslides in early June 2025 marooned 1,500 tourists and blocked arterial roads due to incessant rain.

    What is the Dual Monsoon Pattern? 

    Dual Monsoon Pattern refers to the occurrence of two distinct monsoon phases in a year that affect a region, particularly the Northeastern States of India. These are:

    • Southwest Monsoon (June to September):
      This is the primary monsoon season for most of India. The Bay of Bengal branch of the southwest monsoon brings heavy rainfall to the Northeastern States like Assam, Meghalaya, and Arunachal Pradesh.
    • Retreating/Post-Monsoon (October to December):
      This secondary phase brings additional rainfall, especially to Nagaland, Manipur, Mizoram, and Tripura (NMMT region). This is often accompanied by cyclonic storms originating from the Bay of Bengal.

    How does the dual monsoon pattern affect the disaster preparedness of northeastern States?

    • Extended Vulnerability Period: The presence of both the southwest monsoon (June–September) and the retreating/post-monsoon (October–December) leads to a prolonged rainy season, increasing the duration for which states must stay alert and prepared. Eg: In 2023, flash floods affected parts of Meghalaya in both July and November, stretching disaster response capacities.
    • Recurring Strain on Resources: The back-to-back monsoon cycles put continuous pressure on relief infrastructure, emergency services, and budgetary resources, often without adequate recovery time between events. Eg: In Assam, flood shelters and boats used during June floods had to be reactivated again during October rains, delaying repairs and replenishment.
    • Challenges in Long-term Planning: The dual monsoon system makes it harder to plan and execute infrastructure repair, agricultural recovery, and resettlement efforts, as damage may recur within months. Eg: In Arunachal Pradesh, roads repaired after July landslides were again washed away during October rains in 2022, disrupting connectivity repeatedly.

    Why has infrastructure development lagged in the northeastern States compared to the rest of India?

    • Challenging Geographical Terrain: The region is dominated by mountainous landscapes, dense forests, and seismic zones, which make construction of roads, bridges, and railways technically difficult and cost-intensive. Eg: In Sikkim, frequent landslides and narrow mountain roads delay road-widening and highway projects.
    • Security and Strategic Concerns: The presence of international borders with countries like China, Myanmar, and Bangladesh and historical instances of insurgency have led to delays in project execution due to security concerns and administrative restrictions. Eg: The construction of the India-Myanmar-Thailand Trilateral Highway through Manipur has faced repeated delays due to local unrest and law-and-order issues.
    • Low Political and Economic Prioritisation: Compared to other regions, the Northeast has received less investment in infrastructure due to lower population density, limited industrial base, and less political influence at the national level. Eg: States like Nagaland and Mizoram have limited railway connectivity even today, unlike the rapid expansion seen in western and southern India.

    What are the steps taken by the Indian government? 

    • Strengthened Disaster Response and Early Warnings: The government has deployed NDRF units across the Northeast and enhanced IMD’s region-specific alerts for floods and landslides in states like Assam, Sikkim, and Arunachal Pradesh.
    • Infrastructure Development in Vulnerable Areas: Schemes like NESIDS support critical infrastructure such as flood protection embankments and all-weather roads in remote regions of Manipur and Mizoram.
    • Integration into National Disaster Management Frameworks: NDMA conducts capacity building, mock drills, and implements region-specific guidelines for urban flooding and landslide risk in cities like Gangtok and Guwahati.

    What long-term measures are needed to ensure sustainable disaster management in the Northeast? (Way forward)

    • Region-Specific Infrastructure Planning and Investment: Develop climate-resilient infrastructure suited to the region’s fragile ecology, such as landslide-resistant roads, flood-resistant housing, and robust early warning systems. Eg: The installation of a real-time flood monitoring system in the Brahmaputra basin has improved early evacuation in parts of Assam.
    • Integrated Inter-State and Central Coordination Mechanism: Establish a permanent regional disaster coordination body with participation from all Northeast states and the Centre to plan, share resources, and respond collectively to disasters. Eg: A joint task force involving Assam, Arunachal Pradesh, and Meghalaya could improve flood response across shared river systems like the Barak and Brahmaputra.

    Mains PYQ:

    [UPSC 2024] Flooding in urban areas is an emerging climate-induced disaster. Discuss the causes of this disaster. Mention the features of two such major floods in the last two decades in India. Describe the policies and frameworks in India that aim at tackling such floods.

    Linkage: The Bay of Bengal branch of the monsoon reaches the northeastern States first. These areas usually get a lot of rain during the monsoon, even in years when rainfall is lower than normal. Because of this, the region is naturally more prone to problems like flooding, which often comes with such heavy rain. 

  • Why has net FDI inflow plummeted?

    Why in the News?

    The RBI Bulletin (May 2025) reports that India received a record-breaking $81 billion in gross FDI inflows in FY 2024-25, but retained only $353 million in net FDI, revealing a dramatic divergence in the investment narrative.

    What do gross and net FDI trends indicate about India’s investment climate?

    • Gross FDI inflows are high: India received a record $81 billion in gross FDI in 2024-25, indicating strong headline interest from foreign investors. Eg: Media and government reported this as a sign of a robust investment climate.
    • Net FDI is drastically low: Net FDI dropped to only $353 million, showing that much of the incoming investment is offset by capital outflows, weakening the real impact on the economy. Eg: Rising outward FDI and disinvestment reduced net foreign capital retained in India.
    • Declining FDI-to-GDP ratio: The gross inflow-to-GDP ratio fell from 3.1% (2020-21) to 2.1% (2024-25), and net FDI-to-GDP fell from 1.6% to near zero, reflecting a slowing domestic investment environment despite high gross inflows. Eg: This signals tepid corporate investment and cautious investor sentiment in India.

    What is  Private Equity (PE) and Venture Capital (VC)?

    • Private Equity (PE) refers to investment funds that buy existing companies or large stakes in businesses, often to improve their performance and later sell them for profit. PE typically invests in more mature companies.
    • Venture Capital (VC) is a type of financing that supports early-stage startups and small businesses with high growth potential. VC investors take higher risks in exchange for potentially high returns.

    Why is the rise in Private Equity (PE)/Venture Capital (VC) driven FDI a concern for long-term investment?

    • PE/VC-driven FDI focuses on brownfield investments: These funds mainly acquire existing firms rather than creating new production capacity, limiting contributions to capital formation and technology acquisition. Eg: Investments by Blackstone in Care Hospitals and ChrysCapital in Lenskart.
    • Short investment horizon: PE/VC funds typically have a 3-5 year exit strategy, often selling holdings during stock market booms, which leads to disinvestment rather than sustained growth. Eg: The spike in disinvestment in FY25 was partly due to PE/VC funds liquidating their positions.
    • Limited impact on long-term industrial growth: Since these funds focus on services like fintech and retail rather than manufacturing or infrastructure, they contribute less to enhancing India’s productive capacity. Eg: The declining share of FDI in greenfield projects shows limited greenfield capital formation.

    How does outward FDI suggest India is used for tax arbitrage?

    • High correlation between inward and outward FDI: India shows a strong link between the money flowing in and out, suggesting that funds often enter and exit quickly rather than being invested long-term. Eg: Similar volumes of FDI both coming into and going out of India.
    • Use of tax havens as intermediaries: A significant portion of both inward and outward FDI involves countries like Singapore and Mauritius, known for tax concessions and treaty benefits. Eg: Many Indian companies route investments through these jurisdictions to reduce tax liabilities.
    • ‘Treaty shopping’ for tax benefits: Global investors move capital through India to exploit variations in tax laws, a practice called tax arbitrage, which may not contribute to domestic economic growth. Eg: Research shows India ranked 6th among emerging markets for such correlated FDI flows, indicating use as a conduit for tax optimization.

    What are the effects of declining FDI-to-GDP and GFCF ratios?

    • Reduced contribution to economic growth: Declining FDI-to-GDP and FDI-to-GFCF (Gross Fixed Capital Formation) ratios indicate that foreign investments are becoming a smaller part of India’s overall economy and capital investment, potentially slowing down industrial expansion and technology adoption. Eg: Gross FDI inflows peaked at 7.5% of GFCF in FY21 but have declined sharply since then.
    • Weakening investor confidence: The downward trend signals tepid domestic corporate investment and reduced foreign investor interest, which can affect job creation and long-term economic stability. Eg: Net FDI relative to GDP has declined from 1.6% in 2020-21 to nearly zero in 2024-25, showing declining investor enthusiasm.

    Why should India reform its foreign capital regulations?

    • To curb tax arbitrage and ‘hot money’ flows: Current regulations allow large volumes of inward and outward FDIthrough tax havens, enabling tax optimization rather than genuine investment, which undermines domestic economic goals. Eg: High FDI flows involving Singapore and Mauritius reflect such practices.
    • To promote long-term, productive investments: Reform is needed to encourage FDI that contributes to capital formation, technology acquisition, and industrial growth rather than short-term PE/VC-driven disinvestment. Eg: The rising share of alternative investment funds in FDI has led to increased disinvestment, affecting sustainable growth.

    Way forward: 

    • Strengthen Regulatory Frameworks: Implement stricter rules to curb tax arbitrage and limit quick inflows and outflows via tax havens, ensuring FDI supports genuine, long-term economic growth.
    • Promote Greenfield and Productive Investments: Encourage FDI in new capacity building, manufacturing, and technology sectors over short-term PE/VC deals to boost capital formation, industrial growth, and sustainable development.

    Mains PYQ:

    [UPSC 2013] Though India allowed Foreign Direct Investment (FDI) in what is called multi-brand retail through the joint venture route in September 2012, the FDI, even after a year, has not picked up. Discuss the reasons.

    Linkage: The net FDI-to-GDP ratio has steadily fallen from 1.6% in 2020-21 to zero in 2024-25. This ongoing decline is worrying, even though policymakers continue to make optimistic claims.

  • SHUKR Gene in Flowering Plants

    Why in the News?

    Flowering plants appeared around 130 million years ago and rapidly diversified, puzzling scientists including Charles Darwin, who called it an “abominable mystery”.

    A new study by CSIR-CCMB, Hyderabad, has identified the SHUKR gene, which controls pollen development in flowering plants.

    SHUKR Gene in Flowering Plants

    About the SHUKR Gene in Flowering Plants

    • What is SHUKR? It is a newly discovered gene found in flowering plants like Arabidopsis thaliana. It plays a key role in forming pollen, which plants need to reproduce.
    • Function in the Plant Life Cycle: SHUKR is active during the sporophyte phase (the main plant body stage) and helps in producing healthy, viable pollen.
    • Effect of Gene Loss: If SHUKR is missing or not working, the plant fails to make good pollen, leading to poor or no reproduction.
    • How SHUKR Works: It controls F-box genes, which remove old proteins and replace them with new ones to help pollen grow well.
    • Adaptive Advantage: SHUKR and F-box genes evolve quickly, allowing plants to adjust to harsh conditions like heat, cold, or drought.
    • Evolutionary Origin: This gene first appeared 125 million years ago in eudicots, a plant group that now includes three-fourths of all flowering plants.
    • Why it matters: SHUKR shows that pollen-making is closely linked with the rest of the plant, challenging the earlier belief that these processes were separate.
    • Significance: Climate change causes heat-induced pollen damage in flowering plants, but genes like SHUKR could help develop climate-resilient crops.

    Back2Basics: Darwin’s “Abominable Mystery”

    • Darwin’s Confusion: Charles Darwin was puzzled by the sudden appearance and rapid spread of flowering plants about 130 million years ago — calling it an “abominable mystery”.
    • Mismatch with Evolutionary Pace: According to standard evolution theory, species change slowly over time, but flowering plants diversified very quickly, showing great variety.
    • Genetic Explanation: The SHUKR gene may solve this mystery by showing how flowering plants gained molecular tools to adapt and reproduce faster.
    • New Insight: This discovery offers a genetic explanation for the rapid rise of flowering plants and helps clarify Darwin’s long-standing puzzle.
