    In news: Total Solar Eclipse

    Why in the news?

    A rare Total Solar Eclipse will be visible across North America on April 8.

    What are Eclipses?

    • Eclipses are astronomical events that occur when the sun, moon, and Earth align in specific ways.
    • There are two primary types of eclipses: solar and lunar.
    1. A solar eclipse happens when the moon comes between the sun and Earth during a new moon, blocking out the sun’s light.
    2. Conversely, a lunar eclipse occurs when the Earth is positioned between the sun and the moon during a full moon, casting a shadow on the moon.

    What is a Total Solar Eclipse?

    • During a total solar eclipse, the moon passes between the sun and Earth, entirely covering the face of the sun along a small path of our planet’s surface.
    • This is called the “path of totality.”
    • The daytime sky turns dark, similar to dusk or dawn, and nocturnal animals have been known to wake up, confused into believing night has arrived.

    Stages of a Total Solar Eclipse

    A total solar eclipse unfolds in several distinct stages.

    1. It starts with a partial eclipse phase as the moon begins to pass between Earth and the sun, partially blocking it and leaving the sun looking like it has a crescent shape.
    2. In the subsequent Baily’s Beads phase, points of light from the sun shine around the moon’s edges because of the irregular lunar topography, producing small beads of light.
    3. In the diamond ring phase, a single bright spot appears along the lunar edge even as the sun’s atmosphere leaves a ring of light around the moon. This phenomenon precedes totality.
    4. After totality, the other phases repeat as the moon keeps moving along its path until the eclipse ends.

    Other types of solar eclipses:

    1. Partial Solar Eclipse
    • This happens when the sun, moon and Earth are not exactly lined up.
    • The sun appears to have a dark shadow on only a small part of its surface.
    1. Annular Solar Eclipse
    • An annular eclipse happens when the moon is farthest from Earth. Because the moon is farther away from Earth, it seems smaller. It does not block the entire view of the sun. The moon in front of the sun looks like a dark disk on top of a larger sun-coloured disk. This creates what looks like a ring around the moon.
    • During a solar eclipse, the moon casts two shadows on Earth. The first shadow is called the Umbra. This shadow gets smaller as it reaches Earth. It is the dark centre of the moon’s shadow.
    • The second shadow is called the Penumbra. The penumbra gets larger as it reaches Earth. People standing in the penumbra will see a partial eclipse. People standing in the umbra will see a total eclipse.

    Why don’t solar eclipses happen at every New Moon?

    • The reason is that the Moon’s orbit tilts 5° to Earth’s orbit around the Sun.
    • Astronomers call the two intersections of these paths nodes.
    • Eclipses only occur when the Sun lies at one node and the Moon is at its New (for solar eclipses) or Full (for lunar eclipses) phase.
    • During most (lunar) months, the Sun lies either above or below one of the nodes, and no eclipse happens.

    1. Origin and Rule
    • The Ikshvaku dynasty was a feudatory under the patronage of the Satavahanas.
    • Their capital was located at Vijayapuri, modern-day Nagarjunakonda in Andhra Pradesh.
    • They ruled over the delta of the Krishna and Godavari rivers on the east coast of the Andhra region.
    • They claimed to be descendants of the legendary king Ikshvaku, mentioned in ancient Sanskrit texts such as the Rigveda and Ramayana.
    • The dynasty’s founder was Vasishthiputra Chamtamula, who rose to power after the decline of the Satavahana dynasty.
    1. Cultural Affiliations
    • The Ikshvakus were Shaivites and performed Vedic rites, but they also patronized Buddhism, which flourished during their reign.
    • Under the reign of Vasishthi-putra Ehuvala Chamtamula, the Ikshvaku kingdom reached its zenith, marked by the construction of numerous Hindu and Buddhist shrines.
    • Their inscriptions and coins have been discovered at various archaeological sites, including Nagarjunakonda, Jaggayyapeta, Kottampalugu, Gurazala, Rentala, and Uppugunduru.
    1. Decline:
    • Successive rulers, such as Mathari-putra Vira-purusha-datta, Vasishthi-putra Ehuvala Chamtamula, and Vasishthi-putra Rudra-purusha-datta, contributed to the expansion and governance of the kingdom.
    • By the mid-4th century, the Pallavas had gained control of the former Ikshvaku territory, marking the decline of the dynasty.

    About Phanigiri

    • Phanigiri village derived its name from the shape of the hillock, which appears to be like a snake hood.
    • The word Phani in Sanskrit means snake and Giri means hillock.
    • Studies suggest that the village had a vibrant life from 1000 BC to 18th century AD.
    • Phanigiri is believed to be one of the important Buddhist monasteries strategically located on the hilltop, on the ancient trade route (Dakshinapatha) connecting the west and the east coast of the Deccan.
    • Various stages of earlier excavations here discovered Mahastupa, apsidal Chaityagrihas, Votive stupas, pillared congregation halls, Viharas, platforms with staircases at various levels, octagonal stupa chaitya, 24-pillared mandapam, circular Chaitya.

    Mangal Pandey: A Revolutionary Icon of Indian Independence

    Why in the news?

    It was on April 8th 167 years ago in 1857, Mangal Pandey was hanged.

    Who was Mangal Pandey?

    • Mangal Pandey, born on July 19, 1827, in Nagwa village of the Ballia district in present-day Uttar Pradesh.
    • He belonged to the kingdom of Awadh, which had been treacherously annexed by the British in 1856.
    • At the age of 22, he enlisted as a soldier in the British East India Company’s army, joining the 34th Bengal Native Infantry.

    Recap of his revolutionary activities

    1. Annexation of Awadh
    • The Begums of Awadh had an understanding with the British, and had been abiding by the terms of the agreement.
    • In spite of this, Awadh was annexed, in February 1856, which was greatly resented by the people.
    • Awadh was a region that supplied large numbers of soldiers of war to the Company’s army.
    • There were 75,000 soldiers from Awadh, and almost every agricultural family in the kingdom had a representative in the army.
    • Whatever happened in Awadh was of immediate concern to the Sepoy.
    1. Rise of Resentment
    • The deposition of the Nawab and the confiscation of the villages of taluqdars during the land revenue settlement of 1856 caused outrage.
    • Some 14,000 petitions were received from the Sepoys about the hardships they faced on account of the revenue system.
    • Mangal Pandey represented the discontent that the misery of British rule had brought upon peasant families.
    1. Flashpoint and the mutiny
    • Mangal Pandey was stationed at Barrackpore, near Calcutta (now Kolkata), where he became involved in a significant event that would later be known as the Sepoy Mutiny of 1857.
    • He refused to use the newly introduced Enfield rifle, the cartridges of which had a covering that was believed to be made of animal fat (beef and pork), and which had to be bit open before the cartridges could be used.
    • This was viewed by the soldiers as a direct assault on their religious beliefs by the British who intended to bring an end to their religion and propagate Christianity.
    • On March 29, 1857, Pandey mutinied and fired at his Senior Sergeant Major.
    • He was overpowered and hanged on April 8, 1857, by the order of a Court Martial at Lal Bagan in Barrackpore.
    • His regiment was disbanded, like the 19th infantry at Behrampore, for showing resentment.

  • Forest Fires

    Fighting forest fires with a plan and community cooperation

    Why in the news? 

    The forest staff across the Kerala State are on alert with the onslaught of summer, with temperatures reaching as high as 40-41 degrees Centigrade, unusual for this time.

    Forest Fires in Kerala 

    • Kerala records relatively fewer forest fires compared to several other states in India, including Chhattisgarh, Odisha, Madhya Pradesh, Assam, and Maharashtra.
    • Kerala’s forest cover, occupying 29.65% of the land, is dominated by deciduous and semi-deciduous woods that are drying up, especially on the forest periphery because of it Forest staff in Kerala are on alert
    •  Kerala reported 163 wildfire incidents since January, resulting in the burning of 230 hectares of forest, which is less compared to previous years.
    • Global Forest Watch data indicates 97 VIIRS(Visible Infrared Imaging Radiometer Suit) fire alerts in Kerala between March 15 and 22, with only 5.2% of them classified as high-confidence alerts.Fires were responsible for 0.33% forest cover loss in Kerala between 2001 and 2022 according to Global Forest Watch.

    What is the frequency of forest fires in India?

    •  Escalation Of forest Fire : Forest fire season in India typically spans from November to June, during which hundreds of thousands of small and large fires occur annually. The frequency of fires tends to escalate from February onwards as summer approaches.
    • forest Fires as per (ISFR) : In its 2021 report, the biennial India State of Forest Report (ISFR) released by the Forest Survey of India (FSI) indicates that 35.47% of the forest cover is classified as fire-prone areas.

    Region more prone to forest Fire

    • Fires of severe magnitude occur frequently in dry deciduous forests, whereas evergreen, semi-evergreen, and montane temperate forests are relatively less susceptible to fires.
    • During the November to June period, the forests in Northeast India, Odisha, Maharashtra, Jharkhand, Chhattisgarh, and Uttarakhand face the highest risk of fires.For example in 2021, a string of forest fires occurred in Uttarakhand, Himachal Pradesh, the Nagaland-Manipur border, Odisha, Madhya Pradesh, and Gujarat, including within wildlife sanctuaries.
    • In 2024 forest Fires: According to data from the Forest Survey of India (FSI), Mizoram reported the highest number of forest fires (3,738), followed by Manipur (1,702), Assam (1,652), Meghalaya (1,252), and Maharashtra (1,215).

    Reason behind the forest fires in India 

    The majority of forest fires in India are ignited by human activities, including:

    • Agricultural Burning: Farmers often use fire to clear land for cultivation or to manage crop residues, leading to accidental fires spreading into nearby forests.For example Jhum (slash and burn cultivation)
    • Intentional Arson: Deliberate setting of fires for various reasons, such as land grabbing, hunting, or retaliatory actions.
    • Carelessness: Unattended campfires, discarded cigarettes, or burning of waste materials can spark fires.
    • Climate Conditions: Dry and hot weather conditions during the summer months create favorable conditions for the rapid spread of fires. .For example forest fires has worsen due to climate change as per UNEP

    Plan for Fighting forest Fires 

    • Early Detection: Implement systems for early detection of forest fires, such as fire watchtowers, aerial surveillance, and remote sensing technologies like drones and satellites.
    • Rapid Response: Develop well-trained and equipped firefighting teams capable of swift response to contain fires in their early stages before they escalate.
    • Controlled Burns: Conduct controlled burns during cooler and wetter months to remove excess vegetation and reduce the risk of large-scale wildfires during dry seasons.
    • Firebreaks: Create and maintain firebreaks by clearing vegetation along strategic points to halt the spread of fires.
    • Community Involvement: Educate local communities about fire prevention and train them in firefighting techniques. Encourage community participation in fire management efforts.
    • Equipment and Infrastructure: Ensure availability and proper maintenance of firefighting equipment such as hoses, pumps, bulldozers, and firefighting aircraft.

    Conclusion 

    Forest fires in India, exacerbated by climate conditions, pose significant threats. Kerala’s proactive measures and community involvement highlight effective strategies for prevention and control, crucial in mitigating the increasing frequency of fires nationwide.

    Why green hydrogen presents both major opportunities, significant challenges

    why in the news? 

    Recently, the Ministry of New and Renewable Energy (MNRE) has announced a Rs-496-crore (until 2025-26) scheme to support pilot projects that either test the viability of green hydrogen as a vehicle fuel or develop secure supporting infrastructure such as refuelling stations.

    Objecive of MNRE scheme 

    (i) validation of technical feasibility and performance of green hydrogen as a transportation fuel

    (ii) evaluation of the economic viability of green hydrogen-powered vehicles

    (iii) demonstration of safe operation of hydrogen-powered vehicles and refuelling stations.

    About Green , Blue and grey hydrogen

    The significance of hydrogen fuel vehicles, particularly hydrogen internal combustion engine (ICE) vehicles and hydrogen fuel cell electric vehicles (FCEVs)

    • Zero Carbon Emissions: Both hydrogen ICE vehicles and FCEVs produce zero carbon emissions during operation.
    • Energy Efficiency: While research suggests that burning hydrogen in an ICE vehicle may be less energy-efficient than using it in a fuel cell, FCEVs still offer high energy efficiency compared to traditional internal combustion engine vehicles, particularly those powered by fossil fuels like diesel and petrol.
    • Clean Energy Production: Hydrogen can be produced through various renewable energy sources, such as wind, solar, and hydroelectric power.
    • Lightweight and Increased Payload Capacity: Hydrogen FCEVs typically weigh less than battery electric vehicles (BEVs) due to the lighter weight of hydrogen and the fuel cell stack compared to EV batteries.
    • Long-haul Freight Applications: Research indicates that long-haul FCEVs can carry freight amounts similar to diesel trucks, while BEVs may suffer from a weight penalty due to heavier batteries.  .
    • Diversification of Energy Sources: Hydrogen fuel vehicles offer a viable alternative to battery electric vehicles, providing diversification in energy sources for transportation.

     Challenges 

    • Storage and Transportation Challenges: Developing specialized cylinders capable of safely storing high-pressure green hydrogen is essential. Existing cylinders designed for compressed natural gas (CNG) are not suitable for hydrogen storage
    • Fuel Costs and Infrastructure: Green hydrogen-powered vehicles face challenges in competing with battery electric vehicles (BEVs) due to higher fuel costs and the need for infrastructure development, including hydrogen refueling stations. The cost of establishing and maintaining hydrogen refueling infrastructure is significant, hindering the widespread adoption of hydrogen FCEVs.
    • Safety Concerns: Hydrogen is highly flammable, necessitating robust safety standards and protocols for handling and storing the fuel at refueling stations.

    Conclusion 

    Green hydrogen offers zero emissions, energy efficiency, and diversification in energy sources for transportation. However, challenges like storage, infrastructure costs, and safety concerns hinder widespread adoption, despite MNRE’s support scheme.

    The RBI has decided to introduce a Mobile App of its RBI Retail Direct scheme aimed at facilitating seamless investment in government securities by retail investors.

    What is Retail Direct Scheme?

    • Retail Direct Scheme was rolled out in November 2021, giving access to individual investors to maintain gilt accounts with RBI and invest in government securities.
    • Using this app, investors can buy central and state government bonds as well as Treasury bills.
    • It enables investors to buy securities in primary auctions as well as buy/sell securities through the Negotiated Dealing System-Order Matching system (NDS-OM) platform.
    • A Gilt Account can be compared with a bank account, except that the account is debited or credited with treasury bills or government securities instead of money.

    Treasury Bills:

    • They are promissory notes issued by the RBI on behalf of the government as a short term liability and sold to banks and to the public.
    • The maturity period ranges from 14 to 364 days.
    • They are the negotiable instruments, i.e. they are freely transferable.
    • No interest is paid on such bills but they are issued at a discount on their face value.

     How does it work?

    • Under the scheme, small investors can buy or sell government securities (G-Secs), or bonds, directly without an intermediary like a mutual fund.
    • However, the same tax rules apply to income from G-Secs.
    • The minimum amount for a bid is ₹10,000 and in multiples of ₹10,000 thereafter.
    • Payments may be made through Net banking or the UPI

    Benefits of RDS
