  • What is Aphelion?

    Why in the News?

    Early on July 5, the Earth reached aphelion, its farthest distance from the sun in our year-long journey around our nearest star.

    What is Aphelion? 

    • Aphelion is a term used in astronomy to denote the point in the orbit of a planet or celestial body where it is farthest from the Sun. 
    • The Earth’s orbit around the Sun is not a perfect circle but rather an ellipse, with the Sun situated at one of the two foci of the ellipse. 
    • Aphelion marks the moment when Earth is at its maximum distance from the Sun along this elliptical path.
    • The concept of aphelion was crucial in Johannes Kepler‘s formulation of his laws of planetary motion during the 17th century.

    How far is the Earth from the Sun at aphelion? 

    • At aphelion, which occurs around July 4th– 5th each year, the Earth is approximately 152.1 million kilometers (about 94.5 million miles) away from the Sun. 
    • This distance is about 3.3% greater than its average distance from the Sun, known as its semi-major axis, which is about 147.1 million kilometers.

    Does aphelion affect temperatures on Earth? 

    • Aphelion has a slight effect on temperatures on Earth, but its impact is minimal compared to other factors such as axial tilt and atmospheric circulation patterns. 
    • Despite being farther from the Sun during aphelion, the Earth’s tilt towards the Sun during the northern hemisphere’s summer results in warmer temperatures for that region. 
    • This phenomenon is primarily responsible for the seasons on Earth.

    What would happen if there were no aphelion? 

    • If Earth’s orbit were perfectly circular, without aphelion or perihelion (the closest point to the Sun), the distance between Earth and the Sun would remain constant throughout the year. 
    • This scenario would result in less variation in seasonal temperatures between the northern and southern hemispheres. 
    • The distinct seasons that we experience today, which are essential for ecological diversity and agricultural cycles, would be significantly altered.

    PYQ:

    [2013] Variations in the length of daytime and night time from season to season are due to-

    (a) The earth’s rotation on its axis

    (b) The earth’s revolution round the sun in an elliptical manner

    (c) Latitudinal position of the place

    (d) Revolution of the earth on a tilted axis

  • Factory accidents, a pointer to rusty inspection reform  

    Why in the news?

    In May 2024, an explosion at a reactor in a chemical factory within the Dombivli Maharashtra Industrial Development Corporation (MIDC) area caused fatalities and injuries among workers and local residents.

    Present Scenario in India       

    • India continues to witness frequent fatal industrial accidents, often due to non-compliance with safety regulations, inadequate inspections, and compromised safety practices.
    • Recent incidents, such as the Dombivli MIDC chemical factory explosion, highlight the recurring nature of these accidents and their devastating impact on lives and infrastructure.
    • There is a significant disparity between the number of registered factories and the inspection rates across states like Maharashtra, Gujarat, and Tamil Nadu.

    Causes of fatal industrial accidents   

    • Non-compliance with Safety Regulations: Many industrial accidents occur due to the failure of companies to adhere to mandated safety regulations and standards. Examples include improper maintenance of machinery, lack of safety equipment, and inadequate training of personnel in handling hazardous materials.
    • Inadequate Maintenance and Inspection Practices: Poor maintenance of industrial equipment and facilities can lead to malfunctions and accidents. Insufficient or irregular inspection practices contribute to undetected hazards and safety violations that increase the risk of accidents.
    • Human Error and Unsafe Practices: Accidents often result from human errors such as negligence, fatigue, or lack of training. Unsafe work practices, including shortcuts taken to save time or reduce costs, can compromise safety standards and escalate the likelihood of accidents.

    Need for the right reforms 

    • Strengthening Regulatory Framework: Reforms should focus on updating and strengthening safety regulations to align with international standards and best practices. There is a need to close loopholes and ambiguities in existing laws to enhance clarity and enforceability.
    • Improving Inspection and Enforcement: Enhancing the capacity and effectiveness of regulatory bodies responsible for inspecting industrial facilities. Increasing the number of qualified inspectors, improving their training, and implementing advanced inspection techniques like digital monitoring and real-time compliance checks.
    • Promoting Transparency and Accountability: Establishing transparent mechanisms for reporting and investigating industrial accidents to identify root causes and prevent recurrence.

    What can be the solution? (Way forward)

    • Enhanced Regulatory Oversight: Strengthening and strictly enforcing safety regulations and standards across all industries. Regular updates to ensure regulations are comprehensive, up-to-date with technological advancements, and aligned with international best practices.
    • Improving Inspection and Compliance: Increasing the number of qualified inspectors and improving their training and capabilities.Implementing regular and surprise inspections using modern technologies such as digital monitoring and remote sensing to ensure compliance with safety standards.
    • Promoting Safety Culture: Encouraging a proactive safety culture within industries through training, awareness programs, and incentives for compliance.

  • How urban expansion makes Delhi susceptible to flooding? 

    Why in the news?

    Heavy rain brought Delhi and NCR to a standstill, causing severe water-logging, traffic snarls, power cuts, property damage, and 11 deaths from structural collapses and electrocution.

    • Climate change and rising temperatures have intensified the overflow of rivers and lakes, snowmelt, storm surges (such as hurricanes and cyclones), and abnormally heavy rains. This, coupled with locational vulnerabilities, has resulted in increased instances of urban flooding.

    Principal Reasons Behind Chronic Urban Flooding in Delhi

    • Unchecked Urban Expansion: Rapid, ill-planned urban growth without considering natural topography and drainage patterns.
    • Inadequate Drainage Systems: Existing drainage systems are unable to handle high-intensity rainfall, leading to significant runoff.
    • Concrete Overdevelopment: Excessive construction on low-lying areas and flood plains, leaving little room for water absorption.
    • Destruction of Water Bodies: Reduction of water bodies that could manage floodwaters, with many converted into real estate.
    • Neglect of Water in Urban Planning: Lack of a comprehensive water masterplan that integrates water management into urban development.

    Present Scenario of Rapid Urbanization in Delhi NCR

    • Fastest Urban Expansion: Delhi is one of the fastest-growing cities globally, with its geographic size almost doubling between 1991 and 2011.
    • Population Growth: Predicted to overtake Tokyo as the world’s most populous city by 2030, with an estimated population of 39 million.
    • Urban Sprawl: Expansion primarily on the peripheries, converting rural areas into urban zones, and rapid urbanization in NCR cities like Ghaziabad, Faridabad, Noida, and Gurugram.

    Challenges and Limitations

    • Topographical Neglect: Building in low-lying areas and on flood plains, disrupting natural drainage and increasing flood risks.
    • Inadequate Infrastructure: Insufficient desilting of drains, inadequate stormwater management systems, and improper solid waste management.
    • Lack of a Water Masterplan: Absence of comprehensive planning for clean and wastewater flows, leading to issues like the flooding of new infrastructures like the Pragati Maidan Tunnel.
    • Reduction of green space and water bodies: Conversion of green spaces and water bodies into concrete developments, further aggravating flood situations.
    • Inconsistent Urban Planning: No systematic approach to integrating natural water flows and gradients into urban development plans.

    Recommendations (Way Forward)

    • Integrated Urban Planning: Develop a water masterplan that prioritizes water management in urban development.
    • Protection of Water Bodies: Preserve and restore existing water bodies to manage floodwaters effectively.
    • Sustainable Development: Implement policies to prevent construction in low-lying and flood-prone areas.
    • Infrastructure Improvement: Enhance drainage systems, desilting processes, and solid waste management to reduce water logging.
    • Public Awareness: Increase awareness about the importance of sustainable urban planning and the risks of unchecked urbanization.
    Case study: Copenhagen, Denmark has an excellent “Five Finger Plan” that integrates urban infrastructure, transport, and green spaces. The city emphasizes sustainability, public life, and sensitive development. Indian Government can consider this plane.

  • What are hurricanes, their types?    

    Why in the news?

    Due to Hurricane Beryl sweeping through the Windward Islands, the Indian Men’s cricket team, victorious in the T20 World Cup, finds itself stranded in Barbados.

    What do we know about Hurricane Beryl?

    • Early Category 4 Storm: Hurricane Beryl is the earliest category 4 storm of the Atlantic hurricane season, sustaining winds of at least 130 miles per hour (209 kilometres per hour).
    • Location and Impact: It is currently affecting the Windward Islands in the southern part of the Lesser Antilles, including Barbados, Grenada, and Trinidad and Tobago.
    • Forecast: The National Hurricane Centre has issued warnings for life-threatening winds and storm surges in the affected islands, with the potential for violent winds and flash flooding.
    • Preparations: Local authorities in Barbados have suspended school classes and taken other precautions, such as shutting down the water supply, in anticipation of the hurricane’s impact.
    • Historical Context: Hurricane Beryl is noted as the strongest storm to impact the Windward Islands since Hurricane Ivan in September 2004.

    What are hurricanes and how do they form?

    • Formation: Hurricanes form over warm ocean waters near the equator where warm, moist air rises from the ocean’s surface, creating low air pressure.
    • Fuel: They are fueled by the heat and moisture evaporating from the ocean, forming clouds and spinning due to the Earth’s rotation.
    • Eye Formation: As the storm system intensifies, an eye forms at its centre, with storms rotating counterclockwise north of the equator and clockwise south of it.
    • Impact of Warming World: Warmer sea surface temperatures due to climate change may lead to slower decay of hurricanes upon landfall, potentially increasing their severity.

    Are hurricanes becoming more severe now?

    • Research Findings: Studies suggest that warmer sea surface temperatures contribute to the slower decay of hurricanes, potentially prolonging their destructive impacts inland.
    • Record-Breaking Seasons: The 2020 Atlantic Hurricane season has seen a record number of named storms, indicating a trend towards more frequent and intense hurricane activity.

    What is the difference between a hurricane and a tropical storm?

    • No Fundamental Difference: Hurricanes, typhoons, and cyclones are all types of tropical cyclones, named differently based on their location:
    • Hurricanes: Form over the Atlantic Ocean and the eastern Pacific Ocean.
    • Typhoons: Form in the Northwest Pacific Ocean.
    • Cyclones: Form in the Bay of Bengal and the Arabian Sea.
    • Naming Conventions: The different names signify regional differences but refer to the same meteorological phenomenon of tropical cyclones.

    Way forward: 

    • Implementation of Advanced Forecasting Technologies: Invest in state-of-the-art meteorological tools and satellite technology to enhance the accuracy and lead time of hurricane forecasts.
    • Community Preparedness Programs: Establish comprehensive community outreach programs to educate residents about hurricane risks, evacuation procedures, and emergency shelter locations.

    PYQ Relevance: 

    Q Safeguarding the Indian art heritage is the need of the moment. Comment (10) (UPSC IAS/2018)

    Q Do you agree that regionalism in India appears to be a consequence of rising cultural assertiveness? Argue. (UPSC IAS/2020)

    Mentors’ comment: India, with its landscapes ranging from the world’s highest peaks to low-lying coastal plains, showcases a diverse morphology that has evolved over billions of years. Numerous locations feature a variety of rocks, minerals, and distinctive fossil assemblages. These geological features and landscapes reveal spectacular ‘origin’ stories based on scientific interpretations rather than mythology. India’s tumultuous geological past is etched in its rocks and terrains and should be regarded as part of our non-cultural heritage. The country offers many such examples. Geo-heritage sites serve as educational spaces where people can gain much-needed geological literacy, especially given India’s generally poor regard for this legacy.

    Let’s learn!

    Why in the news?

    India’s turbulent geological history is captured in its rocks and landscapes and should be regarded as part of our non-cultural heritage.

    Scant Traction in India:

    • Lack of Awareness and Importance: Despite international advancements in geological conservation, India has not prioritized geo-conservation, with many fossil-bearing sites destroyed due to development and real estate growth.
    • Destructive Activities: Stone mining activities, covering more than 10% of India’s total area, have led to significant destruction of geological sites, undermining the preservation of these natural laboratories.
    • Neglect of Geological Heritage: There is a paradox in India’s approach—seeking evidence of early life on Mars while destroying crucial geological evidence within its own territory, such as the little-known Dhala meteoritic impact crater.
    • Absence of Legislation: India lacks specific legislation or policies to protect geo-heritage, despite being a signatory to international agreements advocating geological conservation.

    Half-hearted Measures:

    • Abandoned Legislation Attempts: In 2009, a Bill to constitute a National Commission for Heritage Sites was introduced but later withdrawn, indicating a lack of commitment to geo-heritage conservation.
    • Ineffective Notification by GSI: The Geological Survey of India (GSI) has notified 34 geological monuments but lacks regulatory power to enforce preservation measures, leading to threats against these sites.
    • Draft Bill with No Progress: In 2022, the Ministry of Mines drafted a Bill for the preservation and maintenance of geo-heritage sites, but there has been no further progress, reflecting a lack of urgency and follow-through.
    • Recent Cliff Demolition Example: The demolition of part of the Varkala cliff, a designated geological heritage site, by the district administration citing landslide hazards highlights the inadequate protection and respect for such sites.

    Impact:

    • Loss of Scientific Knowledge: The destruction of fossil-bearing sites and other geological features due to development, real estate growth, and stone mining activities results in the permanent loss of invaluable scientific data. This hampers the understanding of India’s geological history and reduces opportunities for education and research in earth sciences.
    • Erosion of Cultural and Natural Heritage: Neglecting geological conservation undermines India’s rich natural heritage, which is integral to the country’s identity. The demolition of sites like the Varkala Cliff demonstrates a disregard for preserving unique geological formations that are part of India’s natural legacy.
    • Missed Economic Opportunities: Geo-heritage sites have the potential to attract tourism, contributing to local and national economies. The lack of legislative protection and promotion of these sites means missed opportunities for sustainable tourism development, which could generate income and create jobs while educating the public about the importance of geological conservation.

    Way forward: 

    • Legislative Framework for Geo-Conservation: Enact specific legislation to protect and conserve geo-heritage sites, similar to the Biological Diversity Act, 2002. This legislation should establish clear guidelines for the preservation, management, and sustainable use of geo-heritage sites, ensuring they are protected from destructive activities and development pressures.
    • National Geo-Conservation Authority: Establish a National Geo-Conservation Authority to oversee the identification, protection, and promotion of geo-heritage sites.  
    • Promotion of Geo-Tourism: Develop and promote geo-heritage sites as sustainable tourism destinations. This includes investing in infrastructure, providing educational resources, and marketing these sites to attract both domestic and international tourists.  

  • Why the Thar Desert on the borders of India and Pakistan is getting greener?

    Why in the news?

    Rajasthan’s barren Thar Desert may turn green, says a recent study in the journal Earth’s Future.  

    About Thar Desert

    • The Thar Desert is the 18th largest subtropical desert globally and is one of the most densely populated deserts.
    • Approximately 40% of the human population in Rajasthan resides in the Thar Desert.
    • It extends from the Sutlej River and is bounded by the Rann of Kutch, the Aravalli Mountains, and the Indus River.
    • About 85% of the Thar Desert is located in India, with the remainder in Pakistan. 
    • In India, it spans across Rajasthan, Gujarat, Haryana, and Punjab as well.
    • Civilizations are believed to have thrived in the Thar region around 50,000 years ago across the extinct Saraswati River.
    • The Desert National Park (home to the endangered Great Indian Bustard, desert fox, desert cat, blackbuck, and Indian gazelle) is situated in the Thar Desert in the northwest Indian state of Rajasthan.

    Why the thar desert getting greener?

    • Climate Change Effects:
        • Alteration of Weather Patterns: Climate change is causing shifts in rainfall distribution in the thar desert area.
        • Potential for Vegetation Growth: The increased precipitation could provide favorable conditions for vegetation growth, contributing to the greening of the desert.
    • Indian Monsoon Dynamics:
        • Westward Extension of Indian Monsoon: The Indian monsoon, known for bringing heavy rainfall to eastern India, is now extending further westward into regions like the Thar Desert.
        • Impact on Moisture and Rainfall: This change in monsoon dynamics could lead to increased moisture and rainfall in the desert region, facilitating the growth of vegetation.
    • Expansion of Indian Ocean Warm Pool (IOWP):
        • Influence on Monsoon Patterns: The Indian Ocean Warm Pool (IOWP) influences monsoon patterns and rainfall distribution over the Indian subcontinent.
        • Westward Expansion due to Climate Change: Climate change is causing the IOWP to expand westward, potentially resulting in increased rainfall over semi-arid regions like the Thar Desert and promoting greening.
    • Water Management Practices:
        • Contribution to Greening: Effective water management practices, such as rainwater harvesting and irrigation techniques like johad, kuis, and kunds, may be playing a role in the greening of the Thar Desert.
        • Utilization of Water Resources: By harnessing and efficiently utilizing available water resources, local communities and authorities can support vegetation growth and ecosystem restoration efforts in the desert.
    • Introduction of Irrigation  
      • Commercial Cropping: Irrigation was introduced during British colonial rule in the 19th and 20th centuries to convert arid and semi-arid ecosystems into cropland.
      • Restrictions on Grazing: The right to graze animals was restricted to landowners who cultivated crops, leading to the transformation of nomadic pastoralists into sedentary agropastoralists.
    Sustainability of this transformation

    • Recent greening activities, largely on arid scrub savannahs, have threatened species adapted to such climates and have been linked to locust outbreaks.
    • The Indira Gandhi Canal project in the 1980s led to extensive crop cover in the Thar Desert, resulting in areas becoming infertile due to waterlogging and salinity.
    • Planting invasive species, such as prosopis juliflora and acacia tortilis, has led to habitat degradation and biodiversity loss.

  • ‘Cold Lava’ Rivers flow in Philippines after Mount Canlaon eruption

    Why in the News?

    • After Mount Canlaon erupted in the Philippines, cold lava started flowing through streets and rivers.
      • It was followed by ashfall, and dangers like floods and mudflows downstream.

    What is Cold Lava?

    • Cold lava, also known as “lahar,” is a mixture of water and rock fragments that flows rapidly down the slopes of a volcano, often triggered by heavy rainfall or volcanic eruptions.
    • The mixture forms a concrete-like substance that destroys everything in its path.
    • This can also include smooth, glassy textures or rough and jagged textures.

    Another example of cold Lava in the world

    • Mount Merapi, Indonesia (2023): An eruption of Mount Merapi resulted in the deaths of at least 23 climbers and spewed ash up to 3,000 meters into the air, covering towns and villages

    How harmful is Cold Lava?

    • Rain can carry cold lava down the slopes of a volcano during an eruption and into the path of nearby towns or villages.
    • According to the United States Geological Survey, cold lava has the power to crush and bury things in its path.
    • It also moves quickly like wet concrete and is considered more destructive than hot lava.

    About Mount Canlaon

    • Mount Canlaon, located in the Philippines, is an active stratovolcano known for its frequent eruptions and volcanic activity.
    • It is situated on the island of Negros in the Visayas region of the Philippines.
    • It is part of the Pacific Ring of Fire, known for its high volcanic activity.
    • It poses hazards such as ash fall, lava flows, pyroclastic flows, and lahars (mudflows) that can endanger nearby communities and agriculture.

  • Why heatwaves have not been included as a notified disaster in the Disaster Management Act?

    Why in the news?

    The current period of intense heat in several regions has once more sparked debates about the potential inclusion of heatwaves as officially recognized disasters under the Disaster Management (DM) Act of 2005.

    What are Notified Disasters?

    • According to the Disaster Management (DM) Act, 2005, a disaster is defined as a “catastrophe, mishap, calamity, or grave occurrence” arising from natural or man-made causes that result in substantial loss of life, destruction of property, or environmental damage and is beyond the coping capacity of the affected community.
    • Funds: The DM Act allows states to draw money from the National Disaster Response Fund (NDRF) and the State Disaster Response Fund (SDRF) for managing these disasters.
    • Current Notified Disasters: There are currently 12 categories of notified disasters: cyclones, drought, earthquake, fire, flood, tsunamis, hailstorms, landslides, avalanches, cloudbursts, pest attacks, and frost and cold waves.

    Why Heatwaves Were Not Included as Notified Disasters?

    • Common Occurrence: Heatwaves were historically considered regular events during summer months in many parts of India. They were not seen as exceptional or unusual disasters warranting specific disaster management provisions under the DM Act, 2005.
    • Perception of Predictability: Unlike sudden-onset disasters such as earthquakes or cyclones, heatwaves were perceived as relatively predictable and part of seasonal weather patterns. This perception led to a belief that they could be managed through general public awareness and local interventions rather than formal disaster response mechanisms.
    • Not fit in definition of Disaster: When the DM Act was formulated, disasters were defined as events that caused substantial loss of life, property, or environmental damage beyond the coping capacity of the affected community. At that time, the impacts of heatwaves were typically viewed as localized health issues rather than widespread disasters.
    • Lack of Urgency: There was a lack of urgency in recognizing heatwaves as disasters requiring national-level response frameworks. The focus of disaster management efforts initially leaned towards more acute and visible calamities like cyclones, floods, and earthquakes.

    Why is the Centre Not Adding Heatwaves as a Notified Disaster Now?

    • Financial Concerns: One of the primary concerns is the potential financial burden of declaring heat waves as a notified disaster. Under the current provisions, the government is obligated to provide monetary compensation for lives lost during notified disasters, which is set at Rs 4 lakh per victim.
    • The reluctance of Finance Commissions: Despite requests from various states, the 15th Finance Commission has not recommended adding heatwaves to the list of notified disasters. They argue that the existing categories adequately cover disaster response needs, and they have provided provisions for states to utilize a portion of the State Disaster Response Fund (SDRF) for local disasters like heatwaves.

    Conclusion: Engage with the Finance Commission and other relevant bodies to reassess the inclusion of heatwaves as a notified disaster. Highlight the evolving nature of heat waves, their increasing frequency, and the need for dedicated funding and support mechanisms.
