  • Rare Proton Emission in Astatine Isotope

    Why in the News?

    In a groundbreaking discovery, an international team of nuclear physicists from Finland has measured the proton emission and half-life of 188Astatine (188At)—the heaviest proton-emitting isotope ever observed.

    What is Proton Emission?  

    • Atomic Structure: Atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons.
    • Radioactive Decay: When atoms are unstable, they become stable by emitting particles through a process called radioactive decay.
    • Common Emissions: Most atoms emit alpha particles, beta particles, or gamma rays during decay.
    • Rare Emission: In very rare cases, an atom can emit a proton, a process known as proton emission.
    • Conditions for Emission: Proton emission occurs only in proton-rich nuclei that lie on the extreme edge of nuclear stability.
    • Detection Difficulty: These atoms are extremely hard to create in laboratories and usually exist for less than a second, making them hard to study.

    Discovery of Proton Emission in 188-Astatine:

    • What is Astatine: Astatine (At) is a radioactive, halogenous element with atomic number 85, belonging to the halogen family (Group 17) on the periodic table. It’s a rarest natural element on Earth, not naturally occurring in significant quantities due to its short half-life.
    • Research Breakthrough: Scientists from Finland, India, and Portugal jointly studied a rare isotope called 188-Astatine.
    • Method: The atom was made by bombarding a silver target with strontium ions in a high-powered accelerator.
    • Observed Event: After its formation, 188-Astatine emitted a proton and transformed into polonium within 190 microseconds.
    • Role of Indian Scientists: Experts from IIT Roorkee used computer simulations to confirm the event and revealed that the atom’s shape resembled a watermelon, elongated and stretched.

    Significance of the Discovery:

    • Scientific First: This was the first recorded instance of proton emission from astatine, a rare and heavy element.
    • Understanding Atomic Limits: The discovery helps scientists learn how unstable atoms behave and where the proton-holding limits of atomic nuclei lie.
    • Contribution to Nuclear Science: It enhances our understanding of element formation in extreme environments like stars and nuclear reactors.

  • [7th June 2025] The Hindu Op-ed: Water management in India needs a new course

    PYQ Relevance:

    [UPSC 2013] Constitutional mechanisms to resolve the inter-state water disputes have failed to address and solve the problems. Is the failure due to structural or process inadequacy or both? Discuss.

    Linkage: India’s water management problems are explicitly stated to be a result of a “fragmented and sectoral approach”. This contrasts sharply with the need for a holistic “new course.” The existing situation is problematic because “rivers and other waterbodies are often interstate and multiple political jurisdictions are involved in administering the same waterbody”.

     

    Mentor’s Comment:  In 2025, global water governance takes a historic turn as the United Nations declares it the International Year of Glaciers’ Preservation and launches the Decade of Action on Cryospheric Science (2025–2034). These initiatives, aligned with World Water Day 2025 and World Day for Glaciers (March 21), focus directly on the vital connections between mountain glaciers, freshwater, and ocean ecosystems. They promote the “Source-to-Sea (S2S)” approach, which integrates water governance from glacial sources all the way to ocean outlets, acknowledging their ecological and hydrological continuity.

    Today’s editorial will talk about water governance in India and the world. It will help with GS Paper I (Geography), GS Paper II (Policy Making) and GS Paper III (Environment).

    _

    Let’s learn!

    Why in the News?

    Scientists and decision-makers need to pay attention to the Source to Sea (S2S) approach.

    What is the theme of World Water Day 2025?

    • Theme: Glacier Preservation
    • 2025 is also declared the International Year of Glaciers Preservation by the United Nations.
    • Marks the start of a Decade of Action on Cryospheric Science (2025-2034).

    Why is it significant?

    • Crucial Source of Freshwater: Glaciers act as natural water reservoirs, supplying freshwater to millions downstream. Their preservation ensures sustained water availability for drinking, agriculture, and ecosystems. Eg: The Himalayan glaciers feed rivers like the Ganga and Brahmaputra, supporting millions of people in India.
    • Indicator of Climate Change: Glaciers are sensitive to global warming; their rapid melting signals climate change impacts. Protecting them helps monitor and mitigate broader environmental risks. Eg: Melting Himalayan glaciers contribute to changing river flows, affecting flood and drought patterns in South Asia.
    • Supports Sustainable Development: Preserving glaciers helps maintain mountain ecosystems and supports downstream communities dependent on glacier-fed waters for their livelihoods and economic activities. Eg: Alpine glaciers support mountain agriculture and tourism, critical to local economies in regions like Uttarakhand and Himachal Pradesh.

    Why is the Source-to-Sea (S2S) approach important for global water governance?

    • Integrated Management of Water Systems: S2S treats freshwater and marine systems as a connected continuum, ensuring that actions upstream (rivers, lakes) consider their impact downstream (coastal and marine environments). Eg: Pollution control in river basins like the Ganges directly affects the health of the Bay of Bengal ecosystem.
    • Improves Coordination Across Jurisdictions: S2S promotes cooperation among multiple stakeholders and political jurisdictions, bridging fragmented governance to manage shared water resources effectively. Eg: The Manila Declaration encourages countries to work together on ridge-to-reef management to protect water quality from land to ocean.
    • Facilitates Sustainable Solutions for Water and Marine Challenges: By addressing the entire water cycle, S2S enables holistic strategies that tackle issues like pollution, water diversion, and habitat loss, benefiting both terrestrial and marine biodiversity. Eg: Initiatives under the SIWI Action Platform connect freshwater and marine experts to develop better water management practices globally.

    What is the cryosphere? 

    The cryosphere includes all frozen water parts of Earth, such as glaciers, snow, sea ice, and permafrost. It helps regulate the climate, reflects sunlight, and stores Earth’s freshwater.

    How does the changing mountain cryosphere impact downstream water resources?

    • Altered Water Flow Patterns: Melting glaciers and shrinking snowpacks change the timing and volume of water flow downstream, leading to seasonal water shortages or floods. Eg: Reduced glacial melt in the Himalayas affects the flow of rivers like the Ganges, impacting water availability for millions.
    • Reduced Water Storage Capacity: Glaciers act as natural reservoirs, storing water during cold months and releasing it slowly. Their retreat means less buffering capacity during dry periods, causing water stress downstream. Eg: Declining glacier size in the Alps affects water supplies for European river basins in summer.
    • Increased Risk of Natural Hazards: Glacier melt can lead to the formation and sudden breach of glacial lakes, causing flash floods and damaging downstream ecosystems and communities. Eg: Glacial Lake Outburst Floods (GLOFs) in the Himalayas pose risks to villages and infrastructure along rivers like the Indus.

    What are the key challenges India faces in managing its water resources? 

    • Groundwater Depletion: Over-extraction of groundwater for irrigation, industrial use, and domestic consumption has led to alarming depletion rates of aquifers. This poses a significant threat to long-term water availability and agricultural productivity. Eg, states like Punjab, Haryana, and Rajasthan report over 100% utilization of groundwater resources, leading to critical water scarcity.
    • Water Pollution: Water pollution from industrial effluents, untreated sewage, and agricultural runoff has made large quantities of freshwater unusable. According to the Central Pollution Control Board, more than 70% of India’s surface water is polluted, with rivers like the Ganga and Yamuna being majorly affected.
    • Climate Change and Erratic Weather Patterns: Changing rainfall patterns, prolonged droughts, and frequent floods induced by climate change are altering water availability. The Indian Meteorological Department has noted a decline in monsoon rainfall, which is critical for replenishing rivers, lakes, and groundwater reserves.

    What are the steps taken by the Indian Government?

    • Formulation and Revision of National Water Policies: The government introduced the first National Water Policy in 1987, and since then, it has been periodically updated to address emerging challenges. The latest draft policies emphasize integrated water resource management and sustainability. Eg, the 2019 draft National Water Policy focuses on water conservation, efficient use, and equitable distribution.
    • Institutional Reforms and Coordination Bodies: Committees have been set up to improve water governance by restructuring key institutions. Eg, in 2015, a committee was formed to merge the Central Water Commission and Central Ground Water Board into a unified National Water Commission to foster better coordination and planning.
    • Promotion of Sustainable and Integrated Approaches: The government supports approaches like Source-to-Sea (S2S) management, which integrates land, freshwater, coastal, and marine resource management. Eg, pilot projects in the Indo-Gangetic basin and Delhi waterbodies are being explored under the S2S framework to address pollution and water quality comprehensively.

    Way forward: 

    • Adopt Source-to-Sea (S2S) Approach Nationwide: Implement integrated water governance that connects glacial sources to coastal ecosystems, ensuring coordinated action across sectors and regions.
    • Strengthen Climate-Resilient Water Infrastructure: Invest in glacier monitoring, early warning systems, and sustainable groundwater management to adapt to climate-induced water variability and safeguard water security.

  • [6th June 2025] The Hindu Op-ed: Is IBC an effective resolution tool? | Explained

    PYQ Relevance:

    [UPSC 2018] How far do you agree with the view that tribunals curtail the jurisdiction of ordinary courts? In view of the above, discuss the constitutional validity and competency of the tribunals in India.

    Linkage: The Insolvency and Bankruptcy Code (IBC), India’s first comprehensive bankruptcy law enacted in 2016, fundamentally relies on a specialized tribunal system for its implementation. This system includes the National Company Law Tribunal (NCLT) and the National Company Law Appellate Tribunal (NCLAT). The effectiveness of the IBC as a resolution tool is intrinsically linked to the efficiency, competency, and operational challenges faced by these tribunals.

     

    Mentor’s Comment:  India’s Insolvency and Bankruptcy Code (IBC), started in 2016, has been running for over eight years now. It has helped recover ₹3.89 lakh crore with a recovery rate of 32.8%, changing how companies deal with unpaid debts. But delays in courts, problems after settlements, and a recent Supreme Court decision on Bhushan Steel have created new worries.

    Today’s editorial will talk about the effectiveness of the Insolvency and Bankruptcy Code (IBC) in India. It will help with GS Paper II (Policy Making) and GS Paper III (Banking).

    _

    Let’s learn!

    Why in the News?

    As India works towards becoming a $5 trillion economy, there is growing discussion about whether the IBC is ready for the future, whether its decisions are respected, and how efficient the courts are in handling cases.

    Why was the Insolvency and Bankruptcy Code (IBC) enacted in India in 2016?

    • To Establish a Time-bound Resolution Mechanism: The IBC aimed to replace India’s slow and fragmented insolvency system with a fast-track process for resolving distressed assets within a maximum of 330 days. Eg: Earlier, recovery through legal channels often took years; under IBC, cases like Essar Steel were resolved with clear timelines.
    • To Shift Control from Debtors to Creditors: It empowered creditors by giving them control over the insolvency process and discouraging willful default. Eg: In the case of Bhushan Steel, creditors approved Tata Steel’s resolution plan, overriding promoter control.
    • To Improve Recovery Rates and Credit Culture: IBC sought to improve debt recovery rates and create a culture of responsible borrowing and repayment. Eg: As per IBBI data, creditors have recovered over ₹3.89 lakh crore with an average recovery rate of 32.8%, much higher than earlier systems.

    What makes IBC the preferred route for debt recovery according to the RBI and IBBI data?

    • Highest Share in Total Recoveries: According to the RBI’s 2024 report, the IBC accounted for 48% of all recoveries made by banks in FY 2023-24, making it the dominant recovery mechanism. Eg: Compared to other channels like DRTs and SARFAESI, IBC recovered nearly half of total dues in just one financial year.
    • Better Realisation Than Liquidation: As per IBBI, resolution plans under IBC are yielding 93.41% of the fair value and 170.1% of liquidation value, showing greater efficiency. Eg: In the case of Electrosteel Steels, creditors recovered more than they would have in a liquidation scenario.
    • Timely Resolution and Settlement: The IBC’s time-bound process has led to early settlements, with 30,310 cases settled before admission, involving defaults worth ₹13.78 lakh crore. Eg: Companies facing insolvency threats often clear dues or settle quickly, improving the overall credit discipline.

    How has the IBC impacted the credit culture and corporate governance in India?

    • Improved Credit Discipline: The IBC has fostered a repayment-oriented credit culture by creating a credible threat of insolvency, discouraging willful defaults. Eg: The Supreme Court observed that “the defaulter’s paradise is lost,” reflecting a clear shift in borrower behavior post-IBC.
    • Reduction in NPAs: The IBC has contributed to a sharp fall in Gross Non-Performing Assets (NPAs), which declined from 11.2% in 2018 to 2.8% in 2024 for scheduled commercial banks. Eg: Many firms have restructured or repaid loans early to avoid IBC proceedings, improving asset quality in the banking sector.
    • Boosted Corporate Governance Standards: Firms resolved under IBC show better board practices, including a rise in the number of independent directors, enhancing transparency and accountability. Eg: A study by IIM Bangalore showed firms post-resolution had more professionalised management and stronger compliance norms.

    What are the key challenges currently affecting the effectiveness of the IBC framework?

    • Judicial Delays and Backlogs: Delays in approvals by the National Company Law Tribunal (NCLT) and prolonged litigation undermine the IBC’s goal of time-bound resolution. Eg: Even after creditor approval, resolution plans like that of Jaypee Infratech have been stuck for years due to legal battles, leading to erosion in asset value.
    • Post-resolution Uncertainty: Lack of legal finality and frequent challenges after plan approval create investor hesitation and risk derailment of settled cases. Eg: In the Bhushan Power and Steel case, a previously approved resolution plan was reopened, shaking confidence in the system.
    • Inadequate Framework for Emerging Assets: The IBC lacks clear mechanisms to deal with issues like intellectual property valuation, employee dues, and tech continuity, making it unfit for resolving non-traditional businesses. Eg: Tech start-ups and IP-heavy firms may not be efficiently resolved under current provisions, leading to value destruction.

    Why is the Bhushan verdict seen as a setback?

    • Erodes Commercial Certainty: The verdict questioned a resolution plan that had already been approved and operational for years, undermining the finality of the IBC process. Eg: The reopening of the Bhushan Power and Steel Ltd. case raised fears that even completed transactions are not immune from future legal scrutiny.
    • Deters Investor Confidence: If resolution applicants fear judicial reversal after making large investments, they may hesitate to participate, weakening the IBC’s appeal. Eg: A successful bidder may now think twice before committing to a resolution plan if legal sanctity isn’t guaranteed.
    • Delays in Execution and Recovery: Continuous litigation post-approval increases the risk of liquidation for otherwise viable firms due to delayed implementation. Eg: In the Bhushan case, years of uncertainty stalled asset utilisation, resulting in a loss of economic value.

    Way forward: 

    • Strengthen Tribunal Infrastructure and Capacity: Expand the capacity of NCLT and NCLAT by appointing more judges, improving case management systems, and digitising proceedings to reduce delays and ensure time-bound resolutions.
    • Ensure Legal Finality and Commercial Certainty: Introduce clear jurisprudential safeguards to prevent post-resolution litigations and uphold the sanctity of approved resolution plans, thereby boosting investor confidence and preserving the IBC’s credibility

  • Should India amend its nuclear energy laws?

    Why in the News?

    India is thinking about changing the Civil Liability for Nuclear Damages Act, 2010, and the Atomic Energy Act, 1962. These changes would let private companies build and run nuclear power plants.

    Why is there a proposal to amend India’s nuclear energy laws?

    • To Attract Private and Foreign Participation: Current laws like the Civil Liability for Nuclear Damage Act (CLNDA), 2010, deter foreign companies due to strict liability provisions. Amending them would enable global firms like Westinghouse (U.S.) and Électricité de France (EDF) to invest and supply nuclear technology.
    • To Meet India’s Clean Energy Targets: India aims to scale up nuclear capacity from 8 GW to 100 GW by 2047 as part of its low-carbon energy transition. Legal reforms are essential to unlock the necessary investments and partnerships to achieve this scale.

    What are the concerns about foreign investment and liability?

    • Foreign Companies Fear Being Blamed After Accidents: They worry they’ll be held legally responsible if something goes wrong, which could cost them a lot of money. Eg: U.S. company Westinghouse and French company Areva stayed away from India’s nuclear sector due to strict liability laws.
    • Indian Law Puts All Blame on the Operator: India’s current law makes the plant operator fully responsible, even if the equipment from foreign suppliers fails. Eg: If a part made by a foreign company causes a problem, only NPCIL (Indian operator) is blamed and has to pay.
    • Old Accidents Still Raise Worries: Events like the Bhopal Gas Tragedy make people cautious about giving foreign companies a free pass on liability. Eg: In 2012, the NDA opposed changes in law that would reduce foreign companies’ responsibility, citing past disasters.

    How will the amendments help achieve 100 GW capacity?

    • Enabling Foreign Participation: Amendments will remove liability-related hurdles, allowing global firms to invest and supply technology. Eg: Westinghouse (U.S.) and EDF (France) may enter Indian projects if liability norms align with international standards.
    • Boosting Domestic-Private Sector Involvement: Changes in laws like the Atomic Energy Act could allow Indian private companies to build and operate reactors. Eg: Companies like L&T and BHEL may contribute to infrastructure and component manufacturing at scale.
    • Attracting Investment in Advanced Reactors (SMRs): Legal clarity could attract funds and partnerships in Small Modular Reactors, helping scale capacity rapidly. Eg: New-age firms working on SMRs may partner with India if assured of returns and limited liability.

    What are Small Modular Reactors (SMRs)? 

    • Small Modular Reactors (SMRs) are compact nuclear power plants that produce up to 300 MW of electricity and are built in factories for easy transport and quicker installation.
    • They use advanced, safer designs with features like passive cooling and are ideal for remote areas, industrial use, and integration with renewable energy sources.

    What challenges exist in small modular reactor (SMR) technology transfer?

    • Profit-Driven Technology Sharing: Private foreign firms transfer technology only if it’s commercially viable, not for strategic or public interest reasons. Eg: U.S. companies will share SMR tech only if returns outweigh security or IP risks.
    • Restrictions by National Governments: Export controls and national security concerns limit what tech can be transferred internationally. Eg: The U.S. government regulates tech transfers; past transfers to China (like AP1000) led to cloning and IP misuse.
    • Partial Transfers and Proprietary Control: Even friendly countries often retain core tech and allow only partial local production. Eg: Russia’s Rosatom allowed India to build sub-components of VVER reactors but kept control over critical hot sections.

    What is the Convention on Supplementary Compensation (CSC)? 

    • The Convention on Supplementary Compensation (CSC) is an international treaty that establishes a global fund to provide prompt compensation to victims of nuclear accidents.
    • It assigns primary liability to nuclear plant operators while limiting supplier liability, ensuring faster financial support and shared responsibility among participating countries.

    Why is the Convention on Supplementary Compensation (CSC) important for nuclear compensation?

    • Ensures Quick Compensation Without Legal Delays: CSC focuses on giving fast financial help to victims of nuclear accidents without long court cases. Eg: After a nuclear incident, funds can be released immediately to affected people, unlike long litigation seen in Bhopal.
    • Fixes Responsibility on the Operator Only: CSC channels all liability to the nuclear plant operator, protecting suppliers unless there’s proven misconduct. Eg: If NPCIL runs the plant, it bears full responsibility, not companies like Westinghouse or Rosatom.
    • Creates an International Compensation Fund: It sets up a multi-tiered fund (including global contributions) to support countries during large-scale accidents. Eg: A country can access a global pool of money through CSC if the cost of a disaster exceeds national capacity.

    Way forward: 

    • Strengthen Legal Framework to Balance Liability and Investment: Amend India’s nuclear laws to align liability rules with international standards like the CSC, ensuring fair responsibility for operators while providing enough protection to attract foreign and private investments.
    • Promote Technology Transfer and Domestic Capacity Building: Create transparent policies and incentives that encourage foreign companies to share advanced nuclear technologies such as Small Modular Reactors (SMRs) with Indian firms, while simultaneously building India’s own manufacturing and operational capabilities to achieve energy targets sustainably.

    Mains PYQ:

    [UPSC 2018] With growing energy needs should India keep on expanding its nuclear energy programme? Discuss the facts and fears associated with nuclear energy.

    Linkage: The article  indicate that discussions are ongoing in India to amend its nuclear liability framework (specifically, the Civil Liability for Nuclear Damages Act (CLNDA), 2010, and the Atomic Energy Act (AEA), 1962). The primary reason for these proposed amendments is to allow private companies to build and operate nuclear energy-generation facilities and to expand India’s nuclear energy capacity from 8 GW to 100 GW by 2047, aligning with the country’s clean energy goals.

    About the Global Energy Investment Report:

    • Origin and Purpose: Officially titled World Energy Investment Report, is the IEA’s flagship annual publication.
    • Published since 2016: To assess investment flows across the global energy system.
    • Scope of Coverage: It tracks investments in fossil fuels, renewables, electricity supply, critical minerals, energy efficiency, R&D, and innovation financing.
    • Strategic Value: The report helps determine if current investments support climate goals and universal energy access.

    Global Energy Investment Report, 2025

    Key Highlights from the 2025 Report:

    • China’s Role: China will account for over 25% of global energy investment, with over $625 billion in clean energy, though it also approved 100 GW of new coal plants in 2024.
    • Global Trends: Clean energy investment will hit $2.2 trillion, over twice the amount spent on fossil fuels, yet still falls short of COP28 targets.
    • Africa’s Investment Gap: Africa’s fossil fuel investment dropped from $125 billion to $54 billion, and it still receives only 2% of global clean energy funds, mainly due to debt burdens.
    • India’s Position: India’s renewables investment rose from $13 billion (2015) to $37 billion (2025), while fossil fuel investment also increased. However, grid and storage spending declined to $25 billion.
    • Financing Barriers: India’s high cost of capital—80% above advanced economies—limits clean energy growth. The “Baku to Belem Roadmap” seeks to mobilize $1.3 trillion by 2035 for such regions.
    • Global Mismatch: While $1 trillion is spent annually on power generation, only $400 billion goes to grid infrastructure, affecting distribution capacity.

    What is a Bird Sanctuary?

    • India’s bird sanctuaries are established under the Wildlife (Protection) Act, 1972 (WLPA).
    • Section 18 of the WLPA empowers State governments to declare wildlife or bird sanctuaries based on ecological or zoological importance.
    • The law prohibits hunting of protected birds and prescribes penalties for violations, including fines and imprisonment.

    About Greater Flamingo (Phoenicopterus roseus):

    • Overview: It is the largest and most widespread flamingo species, found across Africa, southern Europe, and South and Southeast Asia, including India and Pakistan.
    • Presence in India: India hosts both Greater and Lesser Flamingos. Greater Flamingo is the state bird of Gujarat.
    • Behaviour and Diet: These birds form monogamous pairs and get their pink coloration from a diet rich in brine shrimp and algae. They are omnivores, feeding on invertebrates, small fish, algae, and decaying plant matter.
    • Habitat: They prefer saltwater lagoons, mudflats, and saline lakes, and are important indicators of wetland health.
    • Migration Pattern: Every year, 100,000–150,000 flamingos migrate from Gujarat to Mumbai, typically arriving in November and settling in the Thane Creek Flamingo Sanctuary.
    • Migration Triggers: Their movement depends on food availability, water levels, and colony crowding.
    • Conservation Status:
      • IUCN Red List: Least Concern (LC) (species is widespread and abundant)
      • Wildlife Protection Act, 1972: Schedule II (protected but with lesser penalties than Schedule I)
      • CMS (Convention on Migratory Species): Appendix II (species need international cooperation for conservation)
      • CITES (Convention on International Trade in Endangered Species): Appendix II (trade is regulated to avoid overexploitation)

    About the Flamingo Sanctuary at Dhanushkodi:

    • Location: The sanctuary lies in the Gulf of Mannar Biosphere Reserve, spanning 524.7 hectares in Rameshwaram taluk.
    • Habitat: It includes mangroves, sand dunes, mudflats, and marshes, supporting migratory birds, marine life, and sea turtles.
    • Flyway Connection: The site falls along the Central Asian Flyway, a key route for wetland migratory birds.
