  • [13th February 2025] The Hindu Op-ed: Nuclear energy — dangerous concessions on liability

    PYQ Relevance:

    Q) Give an account of the growth and development of nuclear science and technology in India. What is the advantage of a fast breeder reactor programme in India? (UPSC CSE 2017)

     

    Mentor’s Comment: UPSC mains have always focused on nuclear science and technology (2017), and atomic energy (2013).

    In the Union Budget speech on February 1, Finance Minister Nirmala Sitharaman announced plans to amend the Atomic Energy Act and the Civil Liability for Nuclear Damage (CLND) Act. This move is likely to be welcomed by the U.S., where past governments have opposed India’s law because it holds nuclear manufacturers partly responsible for accidents. However, in India, removing supplier liability could be a major concern, as it might weaken nuclear safety measures.

     

    Today’s editorial talks about the Atomic Energy Act and the Civil Liability for Nuclear Damage (CLND) Act. This content will help in GS papers 2 and 3 in mains answer writing.

    _

    Let’s learn!

    Why in the News?

    The mention of plans to amend the Civil Liability for Nuclear Damage Act in the Union Budget is a serious issue that needs attention.

    What is the Atomic Energy Act?

    • The Atomic Energy Act, 1962 is an Indian law that regulates the development, production, and use of nuclear energy for peaceful purposes while ensuring national security. It gives the government exclusive control over nuclear materials, plants, and research and allows the establishment of nuclear power projects. The Act also covers radiation safety, uranium mining, reactor operations, and waste disposal to prevent misuse and ensure public safety.

    What is the Civil Liability for Nuclear Damage Act? 

    • The Civil Liability for Nuclear Damage (CLND) Act, 2010 is an Indian law that defines liability in case of a nuclear accident. It ensures compensation for victims while holding nuclear plant operators accountable.

    Key Features:

    • Operator Liability: The primary financial responsibility for any nuclear accident rests with the plant operator (NPCIL in India), not the supplier.
    • Right of Recourse: Unlike many other countries, India allows operators to seek compensation from suppliers if defective equipment or services cause an accident (Section 17).
    • Liability Cap: Operator liability is capped at ₹1,500 crore (~$180 million), with the government covering additional costs if needed.
    • Exclusion from Global Regimes: India has not joined international nuclear liability agreements like the Convention on Supplementary Compensation (CSC), meaning financial responsibility remains domestic.

    What are the safety and liability concerns related to nuclear energy?

    • Risk of Catastrophic Accidents: Nuclear plant failures can lead to massive radiation leaks, environmental destruction, and long-term health impacts.Example: The Fukushima Daiichi disaster (2011, Japan) resulted from a tsunami, causing multiple reactor meltdowns and widespread radioactive contamination.
    • Design Flaws and Negligence: Suppliers may overlook or downplay safety risks in reactor designs, leading to vulnerabilities. Example: The Three Mile Island accident (1979, USA) occurred due to a known reactor design flaw that the supplier failed to address.
    • Limited Liability for Suppliers: In many countries, nuclear suppliers are indemnified, placing financial liability entirely on plant operators and governments.Example: General Electric (GE), which designed the Fukushima reactors, faced no financial consequences due to Japan’s liability laws.
    • Insufficient Compensation for Victims: Liability caps limit compensation for victims, despite the high costs of nuclear disasters. Example: India’s Civil Liability for Nuclear Damage (CLND) Act caps liability at ₹1,500 crore, whereas Fukushima’s cleanup costs are estimated at ₹20-46 lakh crore.
    • Radioactive Waste and Long-Term Risks: Safe disposal of nuclear waste remains a major challenge, with risks of leaks and contamination lasting thousands of years.Example: The Chernobyl disaster (1986, USSR) left a radioactive exclusion zone that remains uninhabitable nearly 40 years later.

    How does India’s approach to nuclear liability differ from global standards?

    • Operator Liability with Limited Supplier Responsibility: India’s Civil Liability for Nuclear Damage (CLND) Act, 2010, places primary liability on the operator (NPCIL), but allows it to seek compensation from suppliers in case of defective equipment or services (Right of Recourse, Section 17).
      • Global Standard: Most countries fully indemnify suppliers, meaning they bear no financial responsibility after supplying reactors.
      • Example: In Japan, General Electric (GE) faced no liability for the Fukushima disaster (2011), while in India, foreign suppliers fear financial risks if an accident occurs.
    • Liability Cap vs. Unlimited Liability in Some Countries: India caps operator liability at ₹1,500 crore (~$180 million), with additional compensation coming from the government if needed.
      • Global Standard: Some countries, like Germany, impose unlimited liability on operators to ensure full compensation. The U.S. Price-Anderson Act establishes a large industry-backed fund for damages beyond a certain limit.
      • Example: After the Chernobyl disaster (1986, USSR), the Soviet government bore the entire cost (~$235 billion), whereas an Indian accident beyond ₹1,500 crore would shift the financial burden to taxpayers.
    • India is Not Part of Global Nuclear Liability Regimes: India has not signed the Convention on Supplementary Compensation for Nuclear Damage (CSC), which standardizes liability norms and creates an international compensation pool.
      • Global Standard: Most nuclear-powered nations, including the U.S. and Japan, are CSC members, ensuring global financial support for nuclear accidents.
      • Example: If a nuclear accident occurs in France, CSC members contribute to compensation, but in India, all financial burdens remain domestic.

    What are the reasons behind the government’s plan to amend the Atomic Energy Act and the Civil Liability for Nuclear Damage (CLND) Act?

    • Attracting Foreign Investment and Suppliers – The existing CLND Act allows India’s nuclear operator (NPCIL) to seek compensation from foreign suppliers in case of faulty equipment, discouraging companies from supplying reactors. Amendments could limit supplier liability, making India a more attractive market for nuclear investments from countries like the U.S., France, and Russia.
    • Expanding Nuclear Energy Capacity – India aims to increase its nuclear power generation to meet rising energy demands and climate goals. Simplifying liability laws could accelerate agreements with international partners and facilitate the construction of new nuclear plants under deals such as the India-U.S. Civil Nuclear Agreement.

    What are the other implications of increasing nuclear energy reliance?

    • High Economic Costs and Project Delays: Nuclear power plants require massive upfront investments, long construction periods, and frequent cost overruns.
      • Example: The AP1000 reactors in Georgia, USA, were initially estimated at $14 billion but were completed at $36.8 billion—a 250% cost overrun. Similarly, India’s Kudankulam Nuclear Power Plant faced significant delays and cost escalations.
    • Nuclear Waste Management and Environmental Risks: Nuclear energy produces radioactive waste that remains hazardous for thousands of years, requiring secure disposal and long-term monitoring.
      • Example: The Fukushima disaster (2011) led to the release of radioactive material, contaminating land and water, with cleanup costs estimated between ¥35-80 trillion (~₹20-46 lakh crore). India lacks permanent storage facilities for high-level nuclear waste.
    • Geopolitical and Security Concerns: Expanding nuclear energy means higher dependence on foreign suppliers, leading to strategic vulnerabilities and potential external influence.
      • Example: India’s civil nuclear deal with the U.S. (2008) opened doors for technology transfer, but suppliers now demand liability protection before delivering reactors, creating diplomatic pressure.

    Way forward:

    • Strengthen Liability and Safety Frameworks: The government should Amend the Civil Liability for Nuclear Damage (CLND) Act to ensure fair risk-sharing between operators and suppliers.
      • Need to invest in advanced reactor safety technologies (e.g., Small Modular Reactors – SMRs) and strengthen independent regulatory oversight.
    • Develop Robust Waste Management and Indigenous Capabilities: The government should establish permanent disposal sites for high-level nuclear waste with stringent monitoring.
      • Need to enhance domestic nuclear technology (e.g., Thorium-based reactors) to reduce reliance on foreign suppliers and improve energy security.

  • Asteroid 2024 YR4

    Why in the News?

    NASA has identified a newly discovered near-Earth asteroid, 2024 YR4, which has a slightly more than 1% chance of impacting Earth in 2032.

    Asteroid 2024 YR4

    Asteroid 2024 YR4 and its Geographical Features:

    • The asteroid was discovered in December 2024 by an observatory in Chile.
    • It measures between 40 to 100 meters across, making it roughly the size of a football field.
      • The exact size is uncertain because astronomers estimate an asteroid’s size based on its brightness.
    • On December 25, 2024, the asteroid passed within 800,000 kilometers of Earth, which is approximately twice the distance of the Moon.
    • It will fade from sight in April 2025 and will not be visible again until 2028, when it approaches Earth once more.
    • The asteroid is currently rated 3 on the Torino Scale, which measures the risk of impact on a scale from 0 to 10.

    Potential Destruction from 2024 YR4 Impact:

    • If 2024 YR4 collides with Earth, it is expected to release between 8 to 10 megatons of energy, equivalent to multiple nuclear explosions.
    • It injured 1,500 people and damaged thousands of buildings across several cities.
    • In comparison, the Apophis asteroid, discovered in 2004, was initially rated 4 but was later downgraded after further observations ruled out an impact threat.

    How often do Asteroids crash Into Earth?

    • Thousands of small asteroids burn up in Earth’s atmosphere daily due to friction.
    • The Chelyabinsk meteor (2013) exploded over Russia with 30 times the power of the Hiroshima bomb.
    • Asteroids around 40 meters can cause regional destruction if they hit Earth.
    • Large asteroids (1 km+ in size) can trigger global disasters, occurring about once every 260 million years.
    • The Chicxulub asteroid (66 million years ago) led to the extinction of dinosaurs.

    How Space Agencies prevent Asteroid Collisions?

    • NASA and global space agencies work on planetary defense to prevent impacts.
    • In 2022, NASA’s DART mission successfully changed asteroid Dimorphos’s trajectory using kinetic impact.
    • Scientists explore 3 key methods for asteroid deflection:
      • Kinetic Impact:  Using spacecraft to hit an asteroid and alter its path.
      • Gravity Tractors:  Using a spacecraft’s gravity to pull an asteroid off course.
      • Nuclear Explosions: As a last resort, detonating a nuclear device near an asteroid to deflect or destroy it.

  • The science is clear, crowd disasters are preventable

    Why in the News?

    This week in India, a tragic crowd crush at the Maha Kumbh claimed the lives of 30 people.

    What scientific evidence supports the prevention of crowd disasters?

    • Crowd Density Studies: Research indicates that crowd crushes become dangerous at densities of five persons per square meter, with serious risks emerging at seven persons per square meter or more. This evidence underscores the need for effective crowd management to prevent dangerous overcrowding.
    • Predictability of Crowd Behavior: Scientific studies have shown that crowd dynamics can be predicted and managed. By understanding how crowds behave in different environments, planners can implement strategies to avoid conditions that lead to crushes.
    • Historical Data on Past Incidents: Analysis of previous crowd disasters reveals common factors leading to fatalities, such as inadequate space and poor crowd control measures. Lessons learned from these incidents can inform better practices for future events.

    How can effective crowd management practices be implemented at large events?

    • Strategic Planning: Event organizers should create a comprehensive plan that includes crowd flow evaluation, risk assessment, and clearly marked exits and entrances. This planning should involve local officials to ensure safety measures are adequate.
    • Staggered Entry and Exit Times: To reduce peak crowd density, organizers can stagger arrival and departure times for attendees, allowing for a more manageable flow of people into and out of the venue.
    • Use of Barriers: Implementing physical barriers can help segment crowds into smaller groups, reducing the likelihood of dangerous surges. Barriers should be designed to allow for emergency exits if needed.
    • Crowd Monitoring Systems: Utilizing technology for real-time monitoring of crowd density and behaviour can help event staff respond quickly to potential dangers. Mass notification systems can alert staff about growing concerns, enabling timely interventions.
    • Staff Training and Communication: Ensuring that all staff and security personnel are trained in crowd management techniques is essential. Clear communication protocols should be established to relay information quickly during an event.

    What role do policies and regulations play in enhancing crowd safety?

    • Mandatory Safety Regulations: Governments should introduce regulations requiring event organizers to adhere to safety standards that limit crowd density and ensure adequate emergency planning. Such policies can hold organizers accountable for crowd safety.
    • Economic Incentives for Compliance: While event organizers often prioritize profit over safety, regulations can create incentives for them to implement safer practices, such as limiting ticket sales based on venue capacity.
    • Post-Incident Reviews and Accountability: Establishing a framework for reviewing crowd disasters can lead to improved regulations and practices in the future. Accountability measures can encourage compliance with safety standards among event planners and local authorities.
    • Public Awareness Campaigns: Governments can promote awareness about crowd safety among the public, educating attendees on how to behave in crowded situations and the importance of following safety protocols during events.

    What are the steps taken by the government?

    • National Disaster Management Authority (NDMA) Guidelines: The NDMA has formulated guidelines to ensure safe crowd management during mass gatherings. These guidelines include regulating traffic, using barricades, and ensuring adequate police presence to manage crowds effectively.
    • Capacity Evaluation: Before hosting large events, there is a requirement for proper evaluation of the venue’s capacity. This ensures that the infrastructure can handle the expected crowd size without leading to dangerous overcrowding.
    • Use of Technology: The government encourages the deployment of advanced technologies such as CCTV surveillance, drones for aerial monitoring, and public address systems to enhance crowd management and safety.
    • Traffic Management: Effective traffic management strategies are implemented, including displaying route maps, managing unauthorized parking, and controlling pedestrian flow around event venues to prevent bottlenecks.

    Way forward: 

    • Strengthen Regulatory Framework – Governments should enforce stricter crowd safety regulations, mandating capacity limits, emergency preparedness, and real-time crowd monitoring for all large events.
    • Enhance Technological Integration – Deploy AI-based crowd analytics, drone surveillance, and real-time alert systems to monitor crowd density and movement. Training event staff in using these technologies will improve response times and prevent disasters.

  • Why meteorologists are comparing Storm Eowyn to a bomb?

    Why in the News?

    Storm Éowyn has hit the British Isles with very strong winds, especially in Ireland and Scotland.

    What are the meteorological characteristics of Storm Eowyn?

    • Explosive Cyclogenesis: Storm Éowyn qualifies as a “bomb cyclone,” with air pressure at its center dropping 50 millibars within 24 hours, significantly exceeding the 24-millibar threshold for explosive cyclogenesis. This rapid deepening is a hallmark of severe winter storms in the region.
    • Wind Speeds: The storm produced wind gusts exceeding 100 mph, with a record gust of 114 mph reported at Mace Head on Ireland’s west coast. The Met Office issued red warnings for widespread gusts of 80-90 mph, particularly affecting Northern Ireland and central and southern Scotland.
    • Jet Stream Influence: A strong jet stream, with winds exceeding 200 mph, played a crucial role in the storm’s development. The temperature contrast between cold air from the eastern US and warmer air over the North Atlantic contributed to this intensity.

    What impacts it had on affected regions and what are the expected consequences?

    • Power Outages and Damage: Nearly one million properties across the British Isles experienced power outages due to downed trees and damaged infrastructure. Restoration efforts are expected to take several days, with some areas potentially facing up to ten days without power.
    • Transport Disruptions: The storm caused significant disruptions to road and rail services, with many routes blocked or cancelled due to hazardous conditions. Emergency services have been deployed to manage the aftermath.
    • Casualties: Tragically, at least one fatality was reported in Ireland when a tree fell on a vehicle due to the high winds. The overall impact of the storm has raised concerns about safety and emergency preparedness in affected regions.

    How does Storm Eowyn fit into broader climate change trends and patterns of extreme weather events?

    • Climate Change Considerations: While Storm Éowyn’s intensity raises questions about climate change’s role in extreme weather events, current research has not conclusively linked specific storm intensities or frequencies to climate change.
      • The Intergovernmental Panel on Climate Change (IPCC) reports low confidence in observed trends related to extratropical storms over the last century.
    • Future Storm Patterns: There are indications that future winter storms may become more frequent and clustered, leading to increased overall impacts. Additionally, as global temperatures rise, storms may exhibit more extreme wind speeds and rainfall due to a warmer atmosphere’s capacity to hold more moisture.
    • Potential for Sting Jets: There is speculation that Storm Éowyn may have developed “sting jets,” which can produce localized but extremely destructive winds. While their occurrence is difficult to predict, studies suggest that such phenomena may increase with future cyclones as atmospheric conditions evolve.

    Way forward: 

    • Strengthening Infrastructure & Emergency Preparedness – Governments should invest in resilient power grids, reinforced transportation networks, and improved early warning systems to mitigate the impact of extreme storms.
    • Climate Adaptation & Policy Measures – Policymakers should integrate climate resilience into urban planning, enforce stricter building codes, and invest in sustainable land management to reduce vulnerabilities.

  • Can Bhopal waste be safely disposed of?

    Why in the News?

    The Madhya Pradesh High Court gave authorities four weeks to dispose of the waste, nearly 40 years after the gas disaster that killed over 4,000 people and left thousands more injured or disabled.

    What are the plans for the hazardous gas leak waste? 

    • Waste Transportation: The Madhya Pradesh government has successfully transported 358 tonnes of hazardous waste from the Union Carbide facility in Bhopal to the Treatment, Storage, and Disposal Facility (TSDF) in Pithampur, Dhar district, following a court order.
    • Incineration Process: The waste will be incinerated at the Pithampur facility, with an initial timeline of three to nine months for complete disposal, depending on emissions and safety assessments during the process.
    • Emission Controls: To mitigate air pollution, the incinerator will utilize four-layer special filters to ensure that the smoke emitted does not contaminate the surrounding environment.
    • Post-Incineration Measures: After incineration, the resulting ash will be covered with a two-layer membrane and buried in a landfill to prevent any contact with soil and water sources.
    • Expert Supervision: The entire disposal process will be overseen by officials from the Central Pollution Control Board and State Pollution Control Board, ensuring compliance with safety regulations and environmental standards.

    How much has been allocated to incinerate the waste and deposit the residue at a landfill in Pithampur?

    • The Central government has allocated ₹126 crore (approximately $15 million) to facilitate the incineration of this waste and ensure that any resulting residue is safely deposited in a landfill at the Pithampur facility.

    Why have there been protests?

    • Health and Environmental Fears: Residents are worried that the incineration of toxic waste will pose significant health risks and environmental hazards to the local population and surrounding areas, with claims that it could lead to harmful emissions affecting air quality.
    • Historical Context: The protests are fueled by the legacy of the 1984 Bhopal gas tragedy, which resulted in thousands of deaths and long-term health issues. This history has heightened sensitivity to any activities involving hazardous materials in the region.
    • Community Mobilization: Local organizations, such as the ‘Pithampur Bachao Samiti’, have organized bandhs (shutdowns) and demonstrations, leading to widespread participation from residents who are calling for the waste to be returned to Bhopal instead of being incinerated locally.

    What is the 1984 Bhopal gas tragedy?

    The Bhopal gas tragedy, also known as the Bhopal disaster, occurred on the night of December 2-3, 1984, at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh, India.  

    • Chemical Leak: The disaster was triggered by a leak of approximately 40 tons of methyl isocyanate (MIC), a highly toxic gas used in pesticide production. This gas escaped from a storage tank due to a combination of operational failures and safety deficiencies at the plant.
    • Immediate Impact: The gas cloud spread over densely populated areas surrounding the plant, leading to immediate chaos and panic. Official estimates indicate that around 3,787 people died as a direct result of the gas exposure, while other estimates suggest that the death toll could be as high as 15,000 to 20,000 over subsequent years due to related health complications.
    • Injuries and Long-term Effects: Over 558,000 individuals suffered injuries ranging from respiratory problems to permanent disabilities. Many survivors continue to experience health issues related to their exposure to the toxic gas.

    Way forward: 

    • Strengthen Public Engagement and Transparency: Conduct comprehensive awareness campaigns involving scientific experts to address community concerns, ensuring transparent communication about safety measures, emission controls, and environmental safeguards during the incineration process.
    • Enhance Monitoring and Compliance: Implement stringent real-time monitoring of emissions and groundwater quality during and after waste disposal, supervised by independent experts and regulatory bodies, to uphold environmental and public health standards.

  • Need quake warning systems: PM; working to better accuracy by 10-15%, says IMD DG

    Why in the News?

    Recently, PM released the IMD’s Vision Document 2047, outlining a plan to achieve nearly perfect weather forecasts for up to three days and 90% accuracy for forecasts made five days ahead by 2047.

    What is IMD’s Vision Document 2047? 

    • The Vision Document aims for zero-error forecast accuracy for up to three days lead time and 90% accuracy for forecasts issued five days in advance by 2047. This ambitious target reflects India’s commitment to improving weather forecasting capabilities significantly.
    • Focus Areas: The document emphasises enhancing weather surveillance technologies, improving atmospheric observations, and leveraging high-performance computing systems.
      • It also highlights the importance of developing advanced earth system models and data-driven methods, including the use of AI and machine learning.

    Why does India need an Earth warning system? 

    • High Seismic Vulnerability: India lies in a seismically active zone, with regions like Himachal Pradesh, Uttarakhand, and the Northeast being particularly earthquake-prone. Early warning systems can help reduce damage and save lives in these areas. Example: The 2001 Gujarat earthquake caused widespread devastation.
    • Risk to Dense Urban Areas: Major cities like Delhi, Mumbai, and Kolkata are vulnerable to earthquakes. Early warnings can help evacuate people, protect infrastructure, and minimize casualties. Example: A strong earthquake in Delhi could severely impact millions.
    • Limited Preparedness and Response Time: Earthquakes give little to no time for people to react. A warning system could provide crucial seconds or minutes to activate emergency protocols, limiting loss of life and property. Example: The 2015 Nepal earthquake caused devastation in northern India.

    How can India achieve zero-error accuracy in forecasting disasters?

    • Technological Advancements: The implementation of Mission Mausam involves deploying next-generation radars, satellites with advanced instruments, and high-performance computing systems. These tools are crucial for improving the precision of weather predictions.
    • Data Assimilation and Modeling: Enhancing data assimilation processes and developing improved earth system models will contribute to better forecasting accuracy. The integration of AI/ML tools is expected to refine weather predictions further.
    • Capacity Building: The initiative will also focus on building capacity within meteorological services to ensure that no severe weather events go undetected. This includes training personnel and enhancing operational frameworks for the timely dissemination of forecasts.

    What are the steps taken by the Indian Government in the past year?

    • Amendment of the Disaster Management Act: In August 2024, the government introduced the Disaster Management (Amendment) Bill, 2024, in the Lok Sabha.
      • This bill proposes the establishment of Urban Disaster Management Authorities for state capitals and large cities, the creation of disaster databases at national and state levels, and the formation of State Disaster Response Forces to strengthen disaster response capabilities.
    • Investment in Urban Flood Mitigation: In August 2024, India announced plans to invest nearly $300 million over two years to mitigate urban flooding and conserve water in major cities, including Mumbai, Chennai, and Bengaluru.
      • The initiative focuses on expanding water bodies like lakes and constructing drainage systems to manage excessive rainfall during monsoon seasons.
    • Addressing Urban Heat Islands: In June 2024, government officials acknowledged that rapid urbanization has turned cities into “heat traps,” exacerbating the effects of heatwaves.
      • Efforts are underway to implement heat action plans, which include provisioning drinking water, improving medical facilities, rescheduling outdoor work, and increasing green spaces to mitigate urban heat.
    • Enhancement of Early Warning Systems: The government has been working to improve early warning systems for various natural disasters, including floods and heatwaves, to provide timely alerts and reduce the impact on vulnerable populations.
    • Capacity Building and Training: There has been a focus on training and capacity building for disaster response teams at both national and state levels. For instance, In 2024, the NDRF organised a multi-agency mock drill in Assam to simulate a response to a major flood disaster.

    What are the challenges in forecasting a disaster?

    • Data Gaps and Limited Technology: Forecasting requires high-quality, real-time data from advanced technologies like satellite imagery, weather radars, and seismic sensors. However, data scarcity in remote areas or regions with underdeveloped infrastructure hampers accurate predictions.
      • Example: The 2013 Kedarnath floods in India resulted from a cloudburst that was not forecasted in time due to a lack of localized meteorological data and advanced radar systems.
    • Unpredictability of Natural Phenomena: Some disasters, such as earthquakes and tsunamis, are inherently unpredictable because they result from sudden geological shifts.
      • Example: The 2004 Indian Ocean tsunami followed a massive earthquake, but the lack of a regional tsunami warning system in the Indian Ocean made it impossible to alert affected countries in time.
    • Challenges in Communication and Dissemination: Even when forecasts are accurate, ineffective communication of warnings to vulnerable populations due to language barriers, poor outreach, or lack of awareness can render forecasts ineffective.
      • Example: During Cyclone Tauktae (2021) in India, while the forecast was accurate, several fishermen ignored warnings to evacuate, leading to fatalities despite advanced cyclone prediction systems.

    Way forward: 

    • Strengthen Technological and Data Capabilities: Invest in localized weather stations, advanced radar systems, and seismic sensors in remote areas, while leveraging AI and machine learning for precise forecasting and real-time data integration.
    • Enhance Community Awareness and Communication: Develop multilingual, accessible early warning systems and conduct regular public awareness campaigns to ensure timely dissemination and community readiness during disasters.

  • What is Pink Fire Retardant?

    What is Pink Fire Retardant?

    Why in the News?

    Air tankers have dropped thousands of litres of pink fire retardant (PFR) to slow the spread of wildfires in Los Angeles.

    Pink Fire Retardant (PFR) and its properties

    • The PFR is a chemical mixture designed to slow or suppress wildfires by reducing the flammability of vegetation and other materials.
    • The most recognized brand of PFR is Phos-Chek, manufactured by Perimeter Solutions.
    • It is primarily made of ammonium phosphate-based slurry, including:
      • Monoammonium phosphate (80%-90%).
      • Diammonium phosphate.
      • Performance additives for enhanced effectiveness.
      • Pink dye for visibility.
    • It is sprayed as a foam or slurry to coat vegetation ahead of wildfires.
    • It slows combustion by:
      • Depleting oxygen needed for flames.
      • Altering how cellulose (plant material) decomposes, creating non-flammable carbon.
    • Unlike water, which evaporates quickly, PFR’s chemical components remain effective for days or weeks, providing long-term protection.

    Significance of PFR

  • Tirupati stampede: Why stampedes take place, how to mitigate risks

    Why in the News?

    Recently six people lost their lives in a stampede in Tirupati while waiting to collect tokens for Lord Venkateswara’s darshan.

    Why do stampedes take place?

    Stampedes are chaotic and uncontrolled movements of large crowds, often triggered by panic or an urgent rush to move in a confined or crowded space.

    • Venues that exceed their safe capacity can lead to dangerously crowded conditions. When too many people gather in a confined space, the risk of a stampede increases significantly.
    • Inadequate planning and lack of effective crowd control measures, such as clear exits and designated waiting areas, can exacerbate the situation. Poor organisation often leads to confusion and panic among attendees.
    • Narrow pathways, obstacles, and poorly designed event spaces can create bottlenecks during emergencies. These barriers make it difficult for people to move freely and can trap crowds, increasing the risk of crush injuries.

    How does human psychology lead to stampedes?

    • Panic Response: Panic can spread rapidly through crowds, causing individuals to act irrationally. When one person begins to push forward out of fear or urgency, it creates a domino effect where others follow without understanding the situation.
    • External Triggers: Events such as loud noises, sudden movements, or perceived threats (like a fire or an emergency) can trigger panic responses in crowds, leading to stampedes.
    • Psychological Factors: Theories of collective behaviour suggest that in large groups, individuals may act against their own interests when panic sets in.
      • For instance, the desire to escape a perceived danger can override cooperative behaviour, leading to chaotic pushing and shoving.

    How does the physical organisation of spaces contribute to stampedes?

    • Narrow Exits and Blocked Pathways: Limited exits and narrow pathways can create bottlenecks during emergencies, making it difficult for individuals to evacuate quickly.
      • When a crowd is forced to funnel through a small area which leads to panic and chaos, increasing the likelihood of a stampede as people rush to escape.
    • Poorly Designed Crowd Flow: Spaces that do not effectively manage crowd flow can exacerbate congestion.
      • Suppose different groups of people converge at the same point without clear guidance or separation that can lead to confusion and a surge of movement, triggering stampede conditions. Effective crowd management strategies are essential to ensure smooth movement.
    • Inadequate Lighting and Visibility: Insufficient lighting can disorient attendees and hinder their ability to navigate the space safely. In low-light conditions, individuals may struggle to see exits or understand the crowd dynamics, leading to increased panic and disorder during critical moments, which can precipitate a stampede.

    How to better prevent stampedes, or at least, mitigate their risks? (Way forward)

    • Effective Crowd Management: Limit crowd size through pre-registration, schedule staggered entries, and organise queues with barriers and clear signage. Use real-time monitoring tools like CCTV and AI-based systems to manage crowd density.
    • Improved Infrastructure and Emergency Readiness: Design venues with wide pathways, multiple exits, and clear evacuation routes. Provide on-site medical facilities and train staff in crowd control, first aid, and emergency response.
    • Public Awareness and Technology Use: Educate attendees on safety protocols, and use digital tools like online ticketing and mobile alerts to prevent physical queues and guide the crowd calmly during emergencies.

  • The Dam Safety Act of 2021

    Why in the News?

    The Supreme Court has criticized the Union government for its inaction in fully implementing the Dam Safety Act, 2021, nearly five years after its enactment.

    What is the Dam Safety Act of 2021?

    Details Enacted to ensure the structural and operational safety of over 5,700 large dams in India.

    Objectives (Section 3):
    • Prevent dam-related disasters by ensuring dam safety.
    • Establish institutions for monitoring, maintenance, and emergency preparedness.
    Structural Mandate
    • National Committee on Dam Safety (NCDS) (Sections 5–6): Chaired by the Chairperson of the Central Water Commission (CWC) and reconstituted every three years to develop policies, guidelines, and standards.
    • National Dam Safety Authority (NDSA) (Section 9): Implements NCDS guidelines, regulates dam safety standards, and resolves disputes between State Dam Safety Organizations (SDSOs) and dam owners.
    • State Committees on Dam Safety (SCDS) (Section 14): Provide state-level oversight.
    • State Dam Safety Organizations (SDSOs) (Section 15): Monitor and inspect dams at the state level, reporting to NDSA.
    Other Provisions:

     
    • Responsibilities of Dam Owners (Section 38):  Form Dam Safety Units, prepare and implement Emergency Action Plans (EAPs), and conduct regular Comprehensive Safety Evaluations (CSEs).
    • Emergency Preparedness (Section 39):  Mandatory EAPs for rapid response in emergencies.
    • Penalties for Non-Compliance (Section 45):  Imprisonment up to two years, fines, or both for failing to comply with Act provisions.

    Why is Dam Safety a priority concern in India?

    • Third-Highest Number of Dams Globally: India has over 4,407 large dams, following China and the USA.
    • Aging Dams: By 2025, over 1,115 dams will be more than 50 years old; By 2050, 4,250 dams will surpass 50 years of age, with 64 dams exceeding 150 years.
    • Decreasing Storage Capacity: Sedimentation reduces reservoir efficiency, affecting water availability for irrigation, drinking, and hydropower. Ex. Bhakra Dam has experienced 139.86% higher siltation rates than estimated, reducing its lifespan.
    • Structural Vulnerabilities: Poorly designed sedimentation management systems make many dams structurally weak over time. Extreme environmental events, such as floods, can exacerbate these vulnerabilities.
    • Lack of Data and Monitoring: Insufficient documentation of storage loss, sedimentation rates, and other critical metrics leads to a lack of preparedness.
