    deccan

    Central Idea

    • A team of scientists from IIT Kharagpur has discovered evidence of exceptionally high annual rainfall during the volcanic activity that formed the Deccan Traps in India around 66 million years ago.
    • Using a new technique called Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS), the researchers analyzed the isotopic composition of fossil trees from the Cretaceous period.
    • They determined the isotopic composition of the rainfall-derived lake water.

    Nanoscale Secondary Ion Mass Spectrometry (NanoSIMS)

    • NanoSIMS is an advanced analytical technique to determine the composition and distribution of elements and isotopes at a microscopic scale.
    • It allows for high-resolution imaging and quantitative analysis of samples.
    • The technique involves bombarding the sample surface with a focused beam of primary ions.
    • This causes the ejection of secondary ions from the sample surface.
    • The secondary ions are collected and analyzed using a mass spectrometer.
    • The mass spectrometer separates the ions based on their mass-to-charge ratio and measures their abundance.

    Analysis and Findings

    • New Technique: The team used Nanoscale Secondary Ion Mass Spectrometry to analyze oxygen isotopes in fossil trees and measure the isotopic composition of the lake water derived from rainfall.
    • Depleted Oxygen Isotopes: The analysis revealed depleted oxygen isotope values, indicating higher tropical rainfall in India during the terminal Cretaceous period.
    • Link to Paleoclimatic Changes: The increase in rainfall closely corresponded to changes in paleo-atmospheric carbon dioxide levels, suggesting a potential underlying link between the two.

    Implications and Comparison

    • Atmospheric Carbon Dioxide Concentration: The eruption of Deccan Trap lavas released a significant amount of carbon dioxide, raising atmospheric levels to as high as 1,000 ppm.
    • Comparison to Modern Rainfall: The data from fossil trees indicated an annual rainfall of 1,800-1,900 mm, exceeding the average modern rainfall of 1,000-1,200 mm in most parts of peninsular India.
    • Climate Change Predictions: The findings align with predictions made by the Intergovernmental Panel on Climate Change (IPCC) for extreme warming scenarios, suggesting a correlation between high carbon dioxide levels and increased rainfall.

    Climate Models and Future Projections

    • Rising Carbon Dioxide Levels: Fossil fuel emissions have raised carbon dioxide levels from 280 ppm to about 420 ppm in 2023.
    • Impact on Rainfall: Climate models indicate that doubling carbon dioxide levels will intensify atmospheric circulation and subsequently increase rainfall.
    • IPCC AR6 Report: The report warns of a significant increase in the wettest day precipitation and tropical cyclone-associated rainfall if carbon dioxide emissions continue to rise unabated.

    Conclusion

    • The study provides evidence of high rainfall during the volcanic activity that formed the Deccan Traps in India millions of years ago.
    • The findings suggest a correlation between elevated carbon dioxide levels and increased rainfall, supporting predictions made by climate models for future climate change scenarios.

    • The proposed amendments have attracted objections and controversies, raising concerns about dilution of forest protection and potential impacts on biodiversity, forest rights, and national security.

    Forest (Conservation) Amendment Bill, 2023: An overview

    • The Forest (Conservation) Act, 1980, safeguards India’s forest land from unauthorized non-forestry use and allows for compensation in case of diversion.
    • Previous amendments aimed to expand protection, but the current amendments focus on removing ambiguities and clarifying the Act’s applicability on various types of land.
    • The amendments emphasize promoting tree cover, carbon sinks, national security infrastructure, and livelihood opportunities for forest-dwelling communities.

     

    Forest (Conservation) Act, 1980

    • It is the principal legislation that regulates deforestation in the country.
    • It prohibits the felling of forests for any “non-forestry” use without prior clearance by the central government.
    • The clearance process includes seeking consent from local forest rights holders and from wildlife authorities.
    • The Centre is empowered to reject such requests or allow them with legally binding conditions.
    • Process of approval for the diversion of forest land culminates after issuance of final diversion order by the State Government or UT concerned which authorises use of forest land for intended purpose and hands over the land to the user agency.

    Key features

    • Inclusion and Exclusion of Land: The Bill amends the Forest (Conservation) Act, 1980 to make it applicable to land notified as a forest under the Indian Forest Act, 1927 or in government records after the 1980 Act came into effect. Land converted to non-forest use before December 12, 1996, will not fall under the Act’s purview.
    • Exemptions: Certain types of land are exempted from the Act, including land within 100 km of India’s border required for national security projects, small roadside amenities, and public roads leading to habitation.
    • Assignment of Forest Land: The state government requires prior approval from the central government to assign forest land to any private or government entity. The Bill extends this requirement to all entities and allows assignment on terms and conditions specified by the central government.
    • Permitted Activities: The Bill expands the list of permitted activities in forests, including establishing check posts, fencing, bridges, running zoos, safaris, and eco-tourism facilities.

    Controversial parts of the Amendment

    • Dilution Concerns: Some critics argue that the amendments dilute the Supreme Court’s 1996 Godavarman case judgment, which extended protection to forests not officially classified as such.
    • Geographically Sensitive Areas: Projects within 100 km of international borders or the Line of Control would no longer require forest clearance, which raises concerns about the environment and security.
    • Deemed Forests and Tourism: Central protection for deemed forests and restrictions on activities like tourism could be compromised, affecting biodiversity conservation and forest integrity.
    • Impact on Forest Cover: Exempting land near border areas for national security projects may adversely affect forest cover and wildlife in northeastern states, which have high forest cover and are biodiversity hotspots.
    • Potential Adverse Effects: Blanket exemptions for projects like zoos, eco-tourism facilities, and reconnaissance surveys may have negative consequences for forest land and wildlife.

    Opposition and Criticism

    • Northeast States’ Opposition: Some northeastern states objected to forest land being used for defense purposes without their consent.
    • Environmental Groups’ Concerns: Environmental organizations criticized the removal of Central protection for deemed forests and allowing tourism in these areas, risking biodiversity and forest conservation.
    • Name Change Controversy: The proposal to change the name of the Act to Van (Sanrakshan Evam Samvardhan) Adhiniyam faced objections for being non-inclusive and excluding certain regions’ populations.

    Conclusion

    • The Forest (Conservation) Amendment Bill, despite attracting objections and controversies, has received the endorsement of the parliamentary committee.
    • The proposed amendments aim to bring clarity to the Act’s applicability and promote tree cover, national security infrastructure, and livelihood opportunities.

  • The abolition of cantonments: What does it entail for urban local bodies?

    Central Idea

    • Recently, the Ministry of Defence took a significant step towards disbanding cantonments in India with the notification for the abolition of Yol Cantonment in Himachal Pradesh. This move is part of a larger plan to convert military areas into exclusive military stations, while merging civilian areas with neighboring urban local bodies (ULBs).

    Historical Context

    • The 62 cantonments spread unevenly across the country are considered archaic colonial legacies that originated after the East India Company’s victory in the battle of Plassey.
    • These cantonments were primarily established for quartering troops, but over time, civilian populations settled within their jurisdictions to provide support services.
    • The current administration of cantonments is under cantonment boards, which function as deemed municipalities and perform civic duties similar to ULBs

    Their features

    • Cantonment Boards are democratic bodies comprising elected and nominated members.
    • In terms of Entry 3 of the Union List (Schedule VII) of the Constitution of India, Urban Self Governance of the Cantonments and the Housing Accommodation therein is the subject matter of the Union.
    • The Station Commander of the Cantonment is the ex-officio President of the Board, and an officer of the IDES or Defence Estates Organisation is the Chief Executive Officer who is also the Member-Secretary of the Board.
    • They have equal representation of elected and nominated/ex-officio members to balance official representation with democratic composition.
    • They maintain ecological balance while providing better civic facilities to the residents.

    What is the plan?

    • The plan is to carve out the military areas in all cantonments and convert them into “exclusive military stations” with the Army exercising “absolute control” over them.
    • The civilian areas, in turn, will be merged with the local municipalities, which will be responsible for their maintenance among other things.

    Advantages for the Military

    • Focus on Core Responsibilities: By separating civilian areas from military stations, the military commanders would be relieved of non-military responsibilities. This would allow them to concentrate more on their core duties, such as training troops and maintaining war preparedness.
    • Elimination of Political Involvement: In some instances, army officers have found themselves getting involved in local politics within cantonments, despite lacking background and training in this area. The merger of civilian areas into ULBs would reduce the army’s involvement in local political matters.
    • Homogeneous Management: The merger would enable uniform and homogeneous management of military stations strictly under the control of the army. This would facilitate streamlined decision-making processes and enhance operational efficiency within military establishments.
    • Enhanced Security: With civilian areas separated from military stations, there is a potential improvement in security arrangements. Military installations can implement stricter security measures without concerns about civilian populations living in close proximity.
    • Increased Flexibility: Without the burden of managing civilian functions, the military can respond more flexibly to changing security needs and allocate resources more effectively. This flexibility can enhance the overall operational capabilities and readiness of the armed forces.

    Benefits for Civilian Residents

    • Property Regulations: Relief from restrictive property regulations, making it easier for residents to transfer, mutate, and develop properties without excessive limitations.
    • Reduced Inconvenience: Mitigation of road closures within cantonments, resulting in less inconvenience for civilian residents in terms of movement and transportation.
    • Access to Welfare Schemes: Integration with ULBs grants civilians access to social welfare schemes provided by the government, which were previously unavailable due to the cantonment’s non-plan sector status.
    • Economic Opportunities: Removal of stifling restrictions on construction and economic activities encourages growth and urbanization in merged areas, potentially boosting employment and economic opportunities for residents.
    • Municipal Laws: Residents come under the jurisdiction of ULBs, ensuring that municipal laws and services are applicable to them, leading to better governance and provision of essential services such as water supply, sanitation, education, and street lighting.

    Potential Concerns

    • Uncontrolled Construction: There is a possibility that the merger of cantonment areas into ULBs may lead to uncontrolled construction and commercialization, particularly in hill station cantonments. This could result in the loss of the charm and environmental integrity of these areas.
    • Insufficient Services: ULBs may struggle to provide quality services and governance to the merged areas. Existing cities already face challenges in delivering services, and the addition of new areas with limited revenue may further strain the capacity of ULBs, potentially resulting in inadequate infrastructure, healthcare, and other essential services.
    • Environmental Impact: The removal of restrictions on construction and economic activities may have negative environmental consequences, such as increased pollution, strain on natural resources, and encroachment on ecologically sensitive areas. Proper environmental safeguards should be in place to mitigate these potential impacts.
    • Resistance to Resource Allocation: Existing councillors and political constituencies may resist diverting funds from their own areas to support the merged areas. This resistance could impede the equitable distribution of resources and hinder the development and provision of essential services in the merged areas.
    • Capacity Constraints: ULBs may struggle with limited manpower, technical expertise, and administrative capacities to effectively govern and manage the merged areas. The sudden addition of new areas may overwhelm the existing administrative setup, hindering their ability to provide efficient and responsive governance.
    • Revenue Generation: Merged cantonment areas may have limited revenue-generating potential, which can pose challenges for ULBs in generating sufficient funds to sustain and improve services. The existing revenue streams of ULBs may need to be re-evaluated, and new strategies for revenue generation may need to be implemented to support the merged areas.

    Way forward

    • Comprehensive Planning: The government should undertake comprehensive urban planning exercises to ensure orderly and sustainable development in the merged areas.
    • Strengthening ULBs: To address the challenges faced by ULBs, the government should provide adequate financial resources, technical support, and capacity-building programs.
    • Public Participation: Engaging the public and stakeholders in the planning and decision-making processes is crucial. This can be achieved through consultations, public hearings, and feedback mechanisms.
    • Monitoring and Evaluation: Regular monitoring and evaluation mechanisms should be established to assess the progress and impact of the merger. This would help identify any shortcomings or challenges and enable timely corrective measures to be implemented.
    • Collaborative Approach: Collaboration between the central and state governments, ULBs, and other relevant stakeholders is essential. A coordinated approach will facilitate effective decision-making, resource allocation, and the implementation of policies and programs.
    • Long-term Perspective: The merger should be viewed from a long-term perspective, considering the social, economic, and environmental implications. It is important to strike a balance between development aspirations and the preservation of the cultural and environmental heritage of the merged areas

    Conclusion

    • The decision to merge civilian areas of cantonments with ULBs carries both advantages and challenges. While the military stands to benefit from the separation, civilians can expect relief from restrictive regulations and improved access to welfare schemes. However, concerns about uncontrolled development and the ability of ULBs to deliver quality services warrant attention. Future mergers emphasize the need for government intervention to adequately fund cities and support their expanding responsibilities.

  • Gravity Hole in the Indian Ocean

    gravity hole
    The true shape of our Earth

    Central Idea

    • One intriguing phenomenon recently discovered is the presence of a significant “gravity hole” in the Indian Ocean, where the gravitational pull is notably weaker.
    • Recent research sheds light on the possible causes behind this anomaly.

    What is a Gravity Hole?

    • A “gravity hole” refers to a region on Earth where the gravitational pull is significantly weaker compared to the surrounding areas or the global average.
    • It is characterized by a dip or low gravity anomaly.
    • In such areas, the sea level may be lower than average due to the weaker gravitational force acting upon the water.
    • This term is often used to describe specific locations, such as the Indian Ocean geoid low (IOGL), where the gravitational pull is notably diminished compared to nearby regions.
    • The exact causes of gravity holes can vary and may involve factors such as variations in the Earth’s mass distribution or underlying geological features.

    What is Indian Ocean Geoid Low (IOGL)?

    • It is located approximately 1,200 kilometers southwest of the southernmost tip of India.
    • IOGL is an area in the Indian Ocean where the sea level is about 106 meters below the global average.

    Unraveling the Causes of IOGL

    • Discovering the Anomaly: Geophysicist Felix Andries Vening Meinesz first identified the IOGL during a survey in 1948. Since then, it has been confirmed by subsequent ship-based experiments and satellite measurements.
    • Ancient Ocean Hypothesis: Researchers from the Indian Institute of Science conducted computer-simulated models spanning 140 million years. They discovered remnants of an ancient ocean, located approximately 965 kilometers below the Earth’s crust, just beneath Africa.
    • Molten Rock Plumes: The simulations revealed molten rock plumes below Africa, potentially caused by tectonic plates subducting into the mantle. These plumes are believed to be a contributing factor to the IOGL.
    • Possible origination: Researchers said that the IOGL comprises slabs from the Tethys Sea, a long-lost sea that plunged into the depths of the planet millions of years ago. Tethys Sea, which once separated the supercontinents of Gondwana and Laurasia is believed to have perturbed the African Large Low Shear Velocity province.

    Future Perspectives

    • Lack of Seismic Evidence: While the simulated models suggest the presence of molten rock plumes beneath the Indian Ocean, seismographic evidence has yet to confirm their actual existence.
    • Additional Factors at Play: The researchers emphasize that other factors contributing to the gravitational anomaly in the Indian Ocean need to be further explored before reaching a definitive conclusion.
    • Further Research: Continuation of studies, including seismic surveys and detailed modelling, is necessary to gain a comprehensive understanding of the IOGL and its causes.
