  • Electoral Reforms In India

    VVPAT Verification in Elections

    Prelims Only | Polity | Mains Paper 2: Federalism

    Why in the news?

    The Supreme Court has decided to address petitions advocating for a comprehensive verification of Voter Verified Paper Audit Trail (VVPAT) slips in upcoming general elections.

    What are VVPATs?

    • VVPAT machines, attached to Electronic Voting Machines (EVMs), print a slip showing the voter’s choice, allowing voters to verify their vote for 7 seconds before the slip drops into a secured box.
    • The concept emerged in 2010, leading to the creation of prototypes by Bharat Electronics Limited (BEL) and Electronics Corporation of India (ECIL).
    • After trials and feedback, the design was approved in February 2013.
    • The Conduct of Elections Rules, 1961, were amended to incorporate VVPATs.
    • They were first used in Nagaland’s Noksen Assembly constituency in 2013 and were implemented in all polling stations by the 2019 Lok Sabha elections.

    Current VVPAT Slip Counting Protocol

    • In 2018, the ECI consulted the Indian Statistical Institute (ISI) to determine a statistically robust sample size for VVPAT slip verification.
    • Initially, VVPAT slips of one randomly selected polling station per Assembly constituency were counted.
    • This was increased to five polling stations per Assembly seat after a Supreme Court judgment in 2019.
    • The ISI suggested counting VVPAT slips from 479 EVMs to ensure a high confidence level that the proportion of defective EVMs is less than 2%.

    Recent petitions regarding VVPAT

    • Opposition parties advocate for heightened VVPAT verification, ranging from 50% to 100%, to bolster electoral transparency and uphold the sanctity of democratic processes.
    • However, the Election Commission emphasizes the need to balance transparency with operational constraints, citing logistical challenges and potential delays in result declaration.

    Imposition of Anti-Dumping Duty on Sodium Cyanide

    Prelims Only | Economics | Mains Paper 3: Effects Of Liberalization On The Economy, Changes In Industrial Policy and their effects on Industrial Growth

    Why in the news?

    The Directorate General of Trade Remedies (DGTR) has recently recommended the imposition of an anti-dumping duty on sodium cyanide (NaCN) imported from China, the European Union, Japan, and Korea.

    Sodium Cyanide and Its Applications

    • Sodium cyanide is a deadly toxic, white, crystalline compound with the chemical formula NaCN.
    • It is a water-soluble solid, mainly used in gold mining, electroplating, and in the synthesis of organic chemicals.
    • It is hygroscopice. it quickly absorbs water from the air.
    • In gold mining, sodium cyanide is used to dissolve and separate gold from its ores.
    • It plays a pivotal role in various industrial processes, electroplating, metal heat treatment, and the production of insecticides, dyes, pigments, and pharmaceuticals.

    What is Anti-Dumping Duty?

    • An anti-dumping duty is a protectionist tariff that a domestic government imposes on foreign imports that it believes are priced below the price at which it is sold in the exporters’ domestic market.
    • This is imposed with the rationale that these products have the potential to undercut local businesses and the local economy.
    • The World Trade Organization (WTO) operates a set of international trade rules for the regulation of anti-dumping measures.
    • In general, the WTO agreement permits governments to act against dumping “if it causes or threatens material injury to an established industry in the territory of a contracting party.

    Anti-Dumping Mechanism in India:

    • The Anti-Dumping mechanism in India is administered by the Directorate General of Anti-Dumping and Allied Dutites (DGAD) under the Ministry of Finance.
    • The anti-dumping law in India is covered under the Customs Tariff Act, 1975, and the Customs Tariff Rules, 1995.
    • The DGAD conducts anti-dumping investigations to determine if the domestic industry has been hurt by a surge in below-cost imports.

    How is Anti-Dumping Duty calculated?

    • The anti-dumping duty is calculated as the difference between the normal value and the export value of the product.
    • The normal value is the market value of the product in the domestic market, while the export value is the price at which the product is exported to India.
    • The anti-dumping duty is imposed to offset the price difference and prevent the domestic industry from being harmed by cheap imports.

    In news: Gape Limitation

    Prelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    This newscard is an excerpt from the original article published in TH.

    What is Gape Limitation?

    • In ecology, the concept of ‘gape limitation’ sheds light on a simple yet crucial idea: predators can only eat prey that fit into their mouths.
    • It dictates the range of prey accessible to predators, influencing the dynamics of ecological communities.

    Imagine a predator fish species with a relatively small mouth or gape size. This fish species primarily feeds on small aquatic invertebrates like zooplankton and small crustaceans. Due to its limited gape size, it cannot consume larger prey items such as larger fish or large insects.Now, let’s introduce a different predator fish species with a larger mouth or gape size. This predator has a broader diet and can consume a wider range of prey items, including smaller fish and larger invertebrates.In this scenario, the predator with the larger gape size has a competitive advantage over the predator with the smaller gape size. It can exploit a greater variety of prey resources, potentially leading to differences in foraging success, growth rates, and overall fitness between the two predator species.This example demonstrates how gape limitation can influence the feeding ecology and interactions between predator and prey species in an ecosystem.

    Why in the News? 

    The Union Cabinet has sanctioned the setup of three semiconductor facilities as part of the initiative to develop semiconductor and display manufacturing ecosystems in the country. One is in Assam and the other two are in Gujarat.

    Need for Semiconductor hub in India:

    • Right now, only a few countries in the world make computer chips. Due to the issues like COVID-19 pandemic and geopolitical tensions between countries, it’s become clear that we need more countries to manufacture these chips instead of Depending on the single country (Taiwan issue).
    • For example, the TATA Group, working with a company from Taiwan called Powerchip Semiconductor Manufacturing Corporation (PSMC), is building a factory in Gujarat to make chips.

    BACK2BASICS:

    What is a Semiconductor chip? How is it manufactured?

    It is a tiny electronic device made of semiconductor material (usually silicon or germanium) that serves as the basic building block of most electronic circuits. These chips can perform various functions, such as processing data, storing information, or controlling electronic devices.

    What is a transistor?

    A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is a fundamental building block of modern electronic devices and circuits. Transistors can be thought of as electronic switches that can be turned on or off, or can be used to amplify electrical signals.

    What is fabrication technology?

    Fabrication technology, often referred to as semiconductor fabrication technology or semiconductor manufacturing, is the process of creating electronic devices and integrated circuits (ICs) on semiconductor materials such as silicon. It involves a series of complex steps to build electronic components, including transistors, diodes, and resistors, as well as connecting them to create functional electronic circuits.

    What is known as a wafer?

    A wafer refers to a thin, flat slice of semiconductor material, typically made of silicon. Silicon wafers are the primary substrate used in the fabrication of integrated circuits (ICs) and other semiconductor devices.

  • RBI Notifications

    Why RBI has been wary of declaring an early victory over inflation?

    Explained | Economics | Mains Paper 3: Indian Economy

    Why in the news? 

    Recently, the Monetary Policy Committee (MPC), which met here from April 3 to 5, decided to keep the repo rate unchanged at 6.5% and maintain the policy stance of ‘withdrawal of accommodation’ in the monetary policy.

    • Withdrawal of accommodation means reducing the money supply in the system which will rein in inflation further. (Temporary Provision)

    Why the RBI has been wary of declaring an early victory over inflation?

    • Persistent Food Inflation: Despite expectations of moderation in inflation, food inflation has remained a concern, especially due to the high prices of food grains and vegetables. In February, food inflation was at 8.7%, with foodgrain inflation still high at 9.8%.
    • Inflation Gap between Bottom and Top of Urban Population: Food inflation disproportionately affects lower-income deciles more than higher ones. In February, the bottom 20% of the urban population faced 5.5% inflation compared to 4.7% for the top 20%. This pattern is similar in rural areas as well.
    • Management Issues: The RBI faces challenges in managing inflation while maintaining growth, especially when inflation persists due to Geopolitical conditions. While central bank policy moves cannot directly bring down supply shock-driven inflation, they can prevent high prices from spilling over.

     Why RBI has kept policy rates unchanged?

    • High Economic Growth: The RBI is focused on maintaining price and financial stability to sustain high growth. The central bank expects the Indian economy to grow at 7% in fiscal year 2024-25
    • Benign Core Inflation: Benign core inflation, which has declined steadily over the past months, indicates that strong growth has not been inflationary. The RBI finds comfort in the declining core inflation levels
    • Monetary Policy Stance associated with food inflation: The RBI is likely to maintain policy rates until October 2024 to assess evolving risks associated with food inflation. The central bank is cautious and prefers to adopt a risk-minimization mode to align inflation towards the target while supporting growth
    • Global Economic Conditions: The RBI is monitoring global economic trends and external factors that could impact domestic inflation and growth. The central bank is aware of the risks posed by geopolitical tensions, volatility in international financial markets, and geo-economic fragmentation

     

    BACK2BASICS

    The Monetary Policy Committee (MPC)

    • It is a key body responsible for formulating the country’s monetary policy. It  is a statutory body constituted as per Section 45ZB under the RBI Act of 1934 by the Central Government
    •  It is a six-member committee established under the amended Reserve Bank of India Act, of 1934. The MPC’s primary objective is to determine the policy rate required to achieve the inflation target set by the government. The committee consists of the following members:
      • RBI Governor (ex officio chairperson)
      • Deputy Governor in charge of monetary policy
      • An officer of the Bank nominated by the Central Board
      • Three members appointed by the central government
    • The MPC meets at least four times a year, and decisions taken by the committee are binding on the Reserve Bank of India.
    • The committee’s composition ensures a mix of expertise in economics, banking, finance, and monetary policy to effectively manage the country’s Monetary Policy Framework.

     

    Conclusion: The RBI has been cautious due to persistent food inflation impacting lower income groups, challenges in managing it, and the need to assess evolving risks. MPC’s unchanged policy rates reflect this caution amidst high growth and benign core inflation.

  • Health Sector – UHC, National Health Policy, Family Planning, Health Insurance, etc.

    Implementing Universal Health Coverage

    Explained | Indian Society | Mains Paper 2: Health & Education

    Why in the news?

    On the eve of World Health Day (7th April), many countries aim to implement UHC (Universal Health Coverage) in the same way as India introduced its National Health Policy, in 2017. However, there exist challenges in India too for implementing it.

    Background:

    • On December 12, 2012, the UN General Assembly unanimously endorsed a resolution urging countries to accelerate progress towards UHC.
    • In India, the high-level expert group report, submitted to the Planning Commission in 2011, outlined a government intent to increase public financing for health to 2.5% of India’s GDP during the 12th Plan (2012-17).

    BACK2BASICS:

    About National Health Policy, 2017:

    It aims to achieve Universal Health Coverage and deliver quality healthcare services to all at an affordable cost. It focuses on improving health status through preventive, promotive, curative, palliative, and rehabilitative services with an emphasis on quality.

     

    What are the challenges in the Implementation of UHC in India? 

    • Federal Issue: Health is a state subject in India, but UHC policy is envisaged at the national level. This can lead to challenges in coordination between the central government and state governments.
      • While the Directive Principles of State Policy provide a basis for the right to health, the absence of a specific constitutional guarantee may create challenges in ensuring consistent and enforceable healthcare rights.
    • Migrant Population and Urban Slums:  Due to issues such as overcrowding, poor sanitation, and limited infrastructure, a significant portion of the population living in urban slums face issues with the availability and accessibility of Primary Health Services is hard to provide.
    • Lack of Finance: Implementing UHC requires significant financial resources. Reducing out-of-pocket expenditure and strengthening primary healthcare services necessitate substantial investments, which may strain government budgets and require innovative financing mechanisms to ensure sustainability.
    • Lack of Healthcare Infrastructure and Human Resources:  India faces shortages in both infrastructure and human resources, particularly in rural and underserved areas, which hinders efforts to improve healthcare accessibility and quality.
    • The vicious cycle of poverty: The vicious cycle of poverty and poor health perpetuates inequality in various spheres of life which eventually leads to the accessibility of health services.

    Suggestive Measures:

    • Addressing Urban Migrants’ Health Needs: Establishing mobile healthcare units or clinics that can reach migrant communities in urban and peri-urban areas, providing essential primary healthcare services.
    • Reducing Out-of-Pocket Expenditure: Simplifying the reimbursement process by digitizing healthcare payment systems and integrating them with government identification or mobile banking platforms to facilitate easy reimbursement for medical expenses.
    • Creating Inclusive Health Systems: Introducing multilingual and culturally sensitive health information materials and services to bridge language barriers and ensure accessibility for diverse urban populations.
    • Implementing Community-Based Primary Healthcare: Establishing community health centers or clinics in urban and peri-urban areas staffed by trained community health workers who can provide basic healthcare services and referrals.

    Conclusion: Building Constitutional backing, enhancing coordination, and federal with fiscal consensus with adequate infrastructure in addressing urban health needs can improve the reach of the Universal Health Program in India.

  • Goods and Services Tax (GST)

    Next government must urgently fix ‘unnecessarily complex’, counter-productive GST: 13th Finance Commission chair

    Explained | Economics | Mains Paper 3: Indian Economy

    Why in the news? 

    Recently Vijay Kelkar (chaired 13th Finance Commission) attributes frauds in Indirect Tax regimes to high GST rates; Moots switched to a single 12% rate like most other countries.

    Reason behind the need for a Single GST rate:

    • Simplification of the structure: A single GST rate would simplify the structure, making it easier for businesses to comply with the tax system and reducing the complexity of classification issues
    • Promotion of manufacturing and exports: A single GST rate could help promote manufacturing and exports by reducing the burden of multiple rates and making the tax system more predictable
    • Single GST rate in many countries: In many developed and emerging market economies, a single GST or VAT rate has been successful in optimizing tax revenue and minimizing tax disputes for example Singapore, New Zealand, the United Arab Emirates, and Japan, have opted for a single GST or VAT rate
    • Addressing GST frauds: High GST rates can make it lucrative for fraudsters to evade taxes. A single, lower GST rate could potentially reduce the incentive for tax evasion and make the system more transparent
    • Reducing litigation: A single GST rate could help reduce litigation related to classification issues and subjective interpretation of tax rates

    How does the Indian GST model compare with GST in other countries?

    Particulars India  Canada UK Singapore
    Name of GST in the Country Goods and Service tax Federal Goods and Service Tax & Harmonized Sales Tax Value Added Tax Goods and Service Tax
    Standard Rate 0% (for food staples), 5%, 12%, 18% and 28% (+cess on luxury items) GST 5% and HST varies from 0% to 15% 20 %Reduced rates- 5 %, exempt, zero rated 7% Reduced rates- Zero rated, exempt

    Exempt Supplies Sale of land and completed buildings, certain healthcare and educational services, essential food items, etc. Real estate, financial services, rent (Residence), charities, health, education Medical, education, finance, insurance, postal services Real estate, Financial services, Residential rental

    Significance of sharing GST with local bodies:

    • Promoting Co-operative Fiscal-federalism: Sharing GST revenues with local bodies could promote fiscal federalism by ensuring a fair distribution of tax revenues among all tiers of government.
    • Strengthening of their Fiscal base: Equitable sharing of GST with the third tier of government, i.e., local bodies, would strengthen their fiscal base and enable them to undertake investments for vital infrastructure and high-quality public goods
    • Building Fairness and appropriateness: GST is a consumption tax, and taxpayers should see direct benefits accruing from their payment of taxes. An arrangement for sharing GST revenues with local bodies would be fair and appropriate
    • Improves Local governance: Sharing GST revenues with local bodies would bolster the quality of governance provided by local governments, as citizens’ demand for quality public goods will grow louder.

    BACK2BASICS:

    About Goods and Services Tax:

    • GST was introduced through the 101st Constitution Amendment Act, 2016. It is one of the biggest indirect tax reforms in the country.
    • It was introduced with the slogan of ‘One Nation One Tax’.The GST has subsumed indirect taxes like excise duty, Value Added Tax (VAT), service tax, luxury tax etc.
    • It is essentially a consumption tax and is levied at the final consumption point.
    • Tax Structure:
    • Central GST to cover Excise duty, Service tax etc, State GST to cover VAT, luxury tax etc. and Integrated GST (IGST) to cover inter-state trade.
    • IGST per se is not a tax but a system to coordinate state and union taxes.
    • It has a 4-tier tax structure for all goods and services under the slabs- 5%, 12%, 18% and 28%.

    Conclusion: Implementing a single GST rate streamlines compliance, promotes economic growth, and curbs fraud. Sharing GST revenue with local bodies strengthens fiscal bases, fosters fairness, enhances governance, and supports fiscal federalism for equitable distribution.

  • Global Geological And Climatic Events

    In news: Total Solar Eclipse

    Prelims Only | Enviro & Biodiversity | Mains Paper 1:

    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.

    PYQ:

    2013:

    Consider the following phenomena

    1. Size of the sun at dusk

    2. Colure of the sun at dawn

    3. Moon being visible at dawn

    4. Twinkle of stars in the sky

    5. Polestar being visible in the sky

    Which of the above are optical illusions?

    (a) 1, 2 and 3

    (b) 3, 4 and 5

    (c) 1, 2 and 4

    (d) 2, 3 and 5

     

    Practice MCQ:

    Which of the following statements best characterizes a Total Solar Eclipse?

    (a) A total solar eclipse occurs when the Moon partially blocks the Sun, leaving a visible ring of sunlight around the Moon’s silhouette.

    (b) During a total solar eclipse, the Moon completely covers the Sun, casting a shadow on a narrow path on the Earth’s surface called the umbra.

    (c) Total solar eclipses occur more frequently than partial solar eclipses due to the precise alignment of the Sun, Earth, and Moon.

    (d) Total solar eclipses can only be observed from specific locations on Earth, making them rare and highly sought-after astronomical events.

    Who were the Ikshvaku (225-340 A.D)?

    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.
    • Cultural materials included terracotta beads, semi-precious beads, iron objects, Brahmi label inscriptions and holy relic casket.

    Mangal Pandey: A Revolutionary Icon of Indian Independence

    Prelims Only | significant Personalities in History | Mains Paper 1:

    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

    Explained | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    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.

    (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.

  • RBI Notifications

    RBI to launch Mobile App for Retail Direct scheme

    Prelims OnlySchemes | Economics | Mains Paper 3: Indian Economy

    Why in the news?

    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

    • With the government being the borrower, there is a sovereign guarantee for the funds and hence zero risk of default.
    • Also, government securities may offer better interest rates than bank fixed deposits, depending on prevailing interest rate trends.

    How can individuals access G-Sec offerings?

    • Investors wishing to open a Retail Direct Gilt account directly with the RBI can do so through an online portal set up for the purpose of the scheme.
    • Once the account is activated with the aid of a password sent to the user’s mobile phone, investors will be permitted to buy securities either in the primary market or in the secondary market.

    Why Uttarakhand govt wants to evaluate the risk of Glacial Lake Outburst Floods

    Explained | Enviro & Biodiversity | Mains Paper 3: Disaster Management

    Why in the news? 

    Recently, the Uttarakhand government has constituted two teams of experts to evaluate the risk posed by five potentially hazardous glacial lakes in the region.

    Context:

    • The Hazardous Glacial Lakes are prone to Glacial Lake Outburst Floods (GLOFs), the kind of events that have resulted in several disasters in the Himalayan states in recent years.
    • The National Disaster Management Authority (NDMA), which operates under the Union Ministry of Home Affairs, has identified 188 glacial lakes in the Himalayan states that can potentially be breached because of heavy rainfall. Thirteen of them are in Uttarakhand.

    About Glacial Lake Outburst Floods (GLOFs):

    GLOFs are disaster events caused by the abrupt discharge of water from glacial lakes  large bodies of water that sit in front of, on top of, or beneath a melting glacier. As a glacier withdraws, it leaves behind a depression that gets filled with meltwater, thereby forming a lake. Example: 4 october 2023 GLOFs in Sikkim.

    Factors behind the GLOFs:

    • Avalanches or Landslides: Incidents such as avalanches or landslides can also impact the stability of the boundary around a glacial lake, leading to its failure, and the rapid discharge of water.
    • Due to climate change: Rising surface temperatures across the globe, including India, have increased the risk of GLOFs. Studies have shown that around 15 million people face the risk of sudden and deadly flooding from glacial lakes, which are expanding and rising in numbers due to global warming.
    • Rapid infrastructure development in vulnerable areas has also contributed to the spike in such incidents.
    • Sizable ice chunks in the lake: GLOFs can be triggered by various reasons, including glacial calving, where sizable ice chunks detach from the glacier into the lake, inducing sudden water displacement.

    Why are GLOFs under the spotlight?

    • Increased Frequency of GLOFs: Since 1980, GLOFs have become more frequent in the Himalayan region, particularly in southeastern Tibet and the China-Nepal border area. This indicates a concerning trend of glacial melting and lake formation as per Institute of Tibetan Plateau Research in China
    • Extent of Potential Risk: The analysis by  Institute of Tibetan Plateau Research in China suggests that approximately 6,353 sq km of land could be at risk from potential GLOFs.
    • Regional Impacts: Another analysis conducted by Caroline Taylor, Rachel Carr, Stuart Dunning (Newcastle University, UK), Tom Robinson (University of Canterbury, New Zealand), and Matthew Westoby (Northumbria University, UK) indicates that GLOFs are not just a localized issue but have broader regional impacts.
      • Around 3 million people in India and 2 million in Pakistan are identified as facing the risk of GLOFs, highlighting the potential humanitarian consequences of these events.

    What is the situation in Uttarakhand?

    • Past GLOF events: Uttarakhand has experienced two major GLOF events in recent years. The first occurred in June 2013, affecting large parts of the state, particularly the Kedarnath valley, resulting in significant loss of life.
      • The second event happened in February 2021 in Chamoli district, leading to flash floods due to the bursting of a glacier lake.
    • Categorization of Glacial Lakes: Uttarakhand has 13 glacial lakes categorized into three risk levels: ‘A’, ‘B’, and ‘C’.
      • Five highly sensitive lakes fall into the ‘A’ category, including Vasudhara Tal in the Dhauliganga basin (Chamoli district), Maban Lake, Pyungru Lake, and two unclassified lakes in Pithoragarh district.
    • Size and Elevation of High-Risk Lakes: The lakes in the ‘A’ category have areas ranging from 0.02 to 0.50 sq km and are situated at elevations between 4,351 to 4,868 meters above sea level. These characteristics make them particularly vulnerable to glacial lake outburst events.
    • Impact of Rising Temperatures: A 2021 study by the Potsdam Institute for Climate Research (PIK) and The Energy and Resources Institute (TERI) suggests that rising surface temperatures could worsen the situation in Uttarakhand.
      • The state’s annual average maximum temperature may increase by 1.6-1.9 degrees Celsius between 2021-2050, potentially exacerbating the risk of GLOFs.

    Conclusion: Uttarakhand government forms expert teams to assess risk from 5 hazardous glacial lakes prone to GLOFs. With rising temperatures and past disasters, urgent action is needed to mitigate potential catastrophic flooding.
