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
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.
Gravity Hole in the Indian Ocean
The presence of a substantial “gravity hole” in the Indian Ocean, where the gravitational pull is noticeably reduced, is one remarkable phenomenon that was recently observed.
Recent studies have thrown insight on the potential reasons for this oddity.
A gravity hole is what?
A location of Earth is referred to as a “gravity hole” if its gravitational attraction is noticeably lower than that of its surroundings or the global average.
It is distinguished by a dip or anomalous low gravity.
Due to the lesser gravitational pull on the water in these places, the sea level may be lower than usual.
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 AndriesVeningMeinesz 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.
Solar Shooting Stars: Discovering Fiery Rain on the Sun
The Sun’s surface has streaks that resemble meteors, which distinguishes them from shooting stars seen on Earth, according to a stunning discovery revealed by astronomers.
These solar shooting stars, which were seen during the coronal rain phenomena, provide important new information on the intricate dynamics of the Sun.
Observing Solar Shooting Stars and Coronal Rain
Shooting stars on Earth are made up of space rocks or dust particles that burn up in our atmosphere, but solar shooting stars are made up of coronal rain occurrences.
Coronal Rain: The condensation of extremely hot particles from the solar corona causes coronal rain. Plasma condenses into thick clumps that, as a result of the Sun’s powerful gravity, fall back to the surface.
European Space Agency’s Solar Orbiter (SolO): The SolO spacecraft provided valuable observations of solar shooting stars, capturing high-resolution images and monitoring the heating and compression of gas beneath them.
Characteristics of such Stars
Findings: The Solar Orbiter observed the impacts of solar shooting stars for the first time, revealing intense bursts of brightness, upward movement of stellar material, and shock waves that heat up the Sun’s corona.
Unique Features: Unlike Earthly shooting stars, solar shooting stars lack bright tails due to powerful magnetic fields in the Sun’s corona stripping gas from the falling clumps.
Challenging Observations: The magnetic fields’ influence makes the observation of solar meteors challenging, and their true nature remained unknown until these recent observations.
Insights and Implications
Solving the Corona Mystery: Scientists believe that the discovery of solar shooting stars could help explain why the corona, the Sun’s outermost atmosphere, is hotter than the layers beneath it. This puzzles astronomers, as conventional solar models predict increasing temperatures closer to the Sun’s core.
Coronal Rain Formation: Coronal rains are formed by localized temperature drops, causing solar plasma to condense into dense lumps that fall to the Sun’s cooler surface, known as the photosphere, at speeds up to 220,000 miles per hour.
Proximity of Observation: The Solar Orbiter’s close distance of 30 million miles from the Sun allowed for detailed observations of these phenomena, closer than the orbit of Mercury.
