    What is ‘Z’ Category Security?

    Prelims Only | Security Issues | Mains Paper 3: Various Security Forces, Agencies & Their Mandates

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Categories of security

    Mains level: Need for security to politicians

    A noted Parliamentarian from Hyderabad has rejected the ‘Z’ category security by the Central Armed Police Forces (CAPF) accorded to him.

    Security Provisions in India

    • In India, security is provided to high-risk individuals by the police and local government.
    • The level of security needed by any individual is decided by the Ministry of Home Affairs, based on inputs received from intelligence agencies which include the IB and R&AW.
    • Individuals such as PM, home minister, and other officials such as the National Security Advisor generally get security cover because of the positions they occupy.
    • In addition to this, persons who are believed to be under threat also receive security cover.

    What is ‘Z’ Category Security?

    In India, the category covers are X, Y, Y-plus, Z, Z-plus, and SPG (Special Protection Group).

    • X Category: The protectee gets one gunman. Protectees in the Y category have one gunman for mobile security and one (plus four on rotation) for static security.
    • Y Plus category: It receives the cover of two gunmen (plus four on rotation) for mobile security, and one (plus four on rotation) for residence security,
    • Z Category: It has six gunmen for mobile security and two (plus 8) for residence security. They get 10 security personnel for mobile security, and two (plus 8) for residence security.
    • Z Plus Category: It is provided by National Security Guard commandos whereas the other category of security is provided by the Delhi police or the ITBP or CRPF personnel.

    What about Special Protection Group (SPG) Cover?

    • The SPG cover is meant only for the PM and his immediate family.
    • After Indira Gandhi was assassinated by her own security guards in 1984, the Rajiv Gandhi government decided to create a special cadre of security personnel for the PM.
    • In March 1985, following the recommendations of a committee set up by the Home Ministry, a special unit was created for this purpose under the Cabinet Secretariat.
    • This unit, initially called the Special Protection Unit, was renamed as Special Protection Group in April 1985.

  • ISRO Missions and Discoveries

    Chandrayaan-3 set for launch in August

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Chandrayaan-3

    Mains level: Not Much

    ISRO plans to execute the Chandrayaan-3 mission in August this year.

    What is Chandrayaan-3 Mission?

    • The Chandrayaan-3 mission is a follow-up of Chandrayaan-2 of July 2019, which aimed to land a rover on the lunar South Pole.

    Chandrayaan-2: A quick recap

    • Chandrayaan-2 consisted of an Orbiter, Lander and Rover, all equipped with scientific instruments to study the moon.
    • The Orbiter would watch the moon from a 100-km orbit, while the Lander and Rover modules were to be separated to make a soft landing on the moon’s surface.
    • ISRO had named the Lander module as Vikram, after Vikram Sarabhai, the pioneer of India’s space programme, and the Rover module as Pragyaan, meaning wisdom.

    Utility of the Orbiter

    • The Orbiter part of the mission has been functioning normally. It is carrying eight instruments.
    • Each of these instruments has produced a handsome amount of data that sheds new light on the moon and offers insights that could be used in further exploration.

    Inception of Chandrayaan 3

    • The subsequent failure of the Vikram lander led to the pursuit of another mission to demonstrate the landing capabilities needed for the Lunar Polar Exploration Mission proposed in partnership with Japan for 2024.

    Its design

    • The lander for Chandrayaan-3 will have only four throttle-able engines.
    • Unlike Vikram on Chandrayaan-2 which had five 800N engines with a fifth one being centrally mounted with a fixed thrust.
    • Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV).

    Back2Basics: Chandrayaan-1 Mission

    • The Chandrayaan-1 mission was launched in October 2008 was ISRO’s first exploratory mission to the moon, in fact to any heavenly body in space.
    • The mission was designed to just orbit around the moon and make observations with the help of the instruments onboard.
    • The closest that Chandrayaan-1 spacecraft came to the moon was in an orbit 100 km from its surface.

  • Forest Conservation Efforts – NFP, Western Ghats, etc.

    [pib] Definition of Forest in India

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

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Definition of Forests

    Mains level: Not Much

    The Union Ministry of Environment, Forest & Climate Change has informed about the criteria used to define forest in India.

    Defining Forests universally

    • As per the Conference of Parties (CoP) 9-Kyoto Protocol, the forest can be defined by any country depending upon the capacities and capabilities of the country.
    • Forest- Forest is defined structurally on the basis of
    1. Crown cover percentage: Tree crown cover- 10 to 30% (India 10%)
    2. Minimum area of stand: area between 0.05 and 1 hectare (India 1.0 hectare) and
    3. Minimum height of trees: Potential to reach a minimum height at maturity in situ of 2 to 5 m (India 2m)

    India’s definition of Forests

    The definition of forest cover has clearly been defined in all the India State of Forest Report (ISFR) and in all the International communications of India.

    • The forest cover is defined as ‘all land, more than one hectare in area, with a tree canopy density of more than 10 percent irrespective of ownership and legal status.
    • Such land may not necessarily be a recorded forest area. It also includes orchards, bamboo and palm’.

    Classification of forest cover

    In ISFR 2021 recently published has divided the forest cover as:

    1. Inside Recorded Forest Area: These are basically natural forests and plantations of Forest Department.
    2. Outside Recorded Forest Area: These cover mango orchards, coconut plantations, block plantations of agroforestry.

    Back2Basics: Forest Classification in India

    The Forest Survey of India (FSI) classifies forest cover in 4 classes.

    • Very Dense forest: All lands with tree cover (including mangrove cover) of canopy density of 70% and above.
    • Moderately dense forest: All lands with tree cover (including mangrove cover) of canopy density between 40% and 70%.
    • Open forests: All lands with tree cover (including mangrove cover) of canopy density between 10% and 40%.
    • Scrubs: All forest lands with poor tree growth mainly of small or stunted trees having canopy density less than 10%.

  • Wildlife Conservation Efforts

    Places in news: Godavari Estuary in Coringa Wildlife Sanctuary (CWS)

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

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ramsar Convention, Coringa WLS

    Mains level: Not Much

    Godavari Estuary in Coringa Wildlife Sanctuary (CWS) is facing due ignorance despite meeting all nine criteria of Ramsar Convention.

    Godavari Estuary

    • The estuary, including 235.70 sq. km Coringa Wildlife Sanctuary (CWS), is one of the rarest eco-regions on the earth.
    • It is also home to India’s second-largest mangrove cover after the Sundarbans.
    • The CWS is inhabited by 115 endangered fishing cats (Prionailurus viverrinus), Olive Ridley turtles, Indian smooth-coated otter, and saltwater crocodiles.

    What are the nine criteria laid out by Ramsar Convention?

    • Criterion 1: “it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region.”
    • Criterion 2: “it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.”
    • Criterion 3: “it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.”
    • Criterion 4: “it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.”
    • Criterion 5: “it regularly supports 20,000 or more waterbirds.”
    • Criterion 6: “it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.”
    • Criterion 7: “it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity.”
    • Criterion 8: “it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.”
    • Criterion 9: “it regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species.”

    Back2Basics: Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals, and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.

    What are Virtual Digital Assets?

    Prelims Only | Economics | Mains Paper 3: Government Budgeting

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Virtual Digital Assets

    Mains level: Taxing crypto assets

    Recently, The Central Board of Direct Taxes (CBDT) issued detailed guidelines on the Tax Deducted at Source (TDS) rule for Virtual Digital Assets (VDAs) such as cryptocurrencies .

    What are Virtual Digital Assets?

    • To define the term “virtual digital asset”, a new clause (47A) is proposed to be inserted into section 2 of the Act.
    • A virtual digital asset is proposed to mean any information or code or number or token (not being Indian currency or any foreign currency):
    1. Generated through cryptographic means or otherwise
    2. Providing a digital representation of value that is exchanged with or without consideration with the promise or representation of having inherent value
    3. Functions as a store of value or a unit of account and includes its use in any financial transaction or investment, but not limited to, investment schemes
    4. Can be transferred, stored, or traded electronically.
    • Non-fungible token (NFT) and; any other token of similar nature are included in the definition.

    Why tax them?

    • Popularity: Virtual digital assets have gained tremendous popularity in recent times and the volumes of trading in such digital assets have increased substantially.
    • Growing market: Further, a market is emerging where payment for the transfer of a virtual digital asset can be made through another such asset.
    • Increased transactions: There has been a phenomenal rise in such transactions and the magnitude and frequency of these transactions have made it imperative to provide for a specific tax regime.
    • Prevalence of gifting: The gifting of virtual digital assets is also a popular mode of exchange.

    Key takeaways from the FM’s speech

    • The bill provides for the definition of virtual digital assets which is wide enough to cover emerging digital assets including NFT, assets in metaverse, cryptocurrencies, etc.
    • This recognition of digital assets under income tax is NOT akin to granting legal status.

    What is Bomb Cyclone?

    Prelims Only | Enviro & Biodiversity | Mains Paper 1: Geographical Features & Their Location

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Bomb Cyclone, Bombogenesis

    Mains level: Not Much

    Major cities such as New York and Boston in US are witnessing a “Bomb Cyclone” characterized by the explosive power of rapid drops in atmospheric pressure.

    What is Bomb Cyclone?

    • A bomb cyclone is a large, intense mid-latitude storm that has low pressure at its center, weather fronts and an array of associated weather, from blizzards to severe thunderstorms to heavy precipitation.
    • It becomes a bomb when its central pressure decreases very quickly—by at least 24 millibars in 24 hours.
    • When a cyclone “bombs,” or undergoes bombogenesis, this tells us that it has access to the optimal ingredients for strengthening, such as high amounts of heat, moisture and rising air.

    Why is it called a bomb?

    • Most cyclones don’t intensify rapidly in this way.
    • Bomb cyclones put forecasters on high alert, because they can produce significant harmful impacts.

    Its etymology

    • The word “bombogenesis” is a combination of cyclogenesis, which describes the formation of a cyclone or storm, and bomb, which is, well, pretty self-explanatory.
    • This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters.
    • The formation of this rapidly strengthening weather system is a process called bombogenesis, which creates what is known as a bomb cyclone.

    How does it occur?

    • Over the warmer ocean, heat and moisture are abundant.
    • But as cool continental air moves overhead and creates a large difference in temperature, the lower atmosphere becomes unstable and buoyant.
    • Air rises, cools and condenses, forming clouds and precipitation.

    Where does it occur the most?

    • The US coast is one of the regions where bombogenesis is most common.
    • That’s because storms in the mid-latitudes – a temperate zone north of the tropics that includes the entire continental US – draw their energy from large temperature contrasts.
    • Along the US East Coast during winter, there’s a naturally potent thermal contrast between the cool land and the warm Gulf Stream current.

    President quotes Thirukkural while addressing Parliament

    Prelims Only | History | Mains Paper 1: Arts & Culture

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Thirukkural

    Mains level: Ancient sangam literature

    President Ram Nath Kovind quoted a couplet from Thirukkural while addressing the joint Houses of Parliament for Budget Session.

    What did the President quote?

    • ‘Karka Kasadara Karpavai Kattrapin Nirka Atharku Thaka’ was the couplet chosen by him to reiterate the importance of the New Education Policy.
    • The couplet insists on thorough and flawless learning and adhering to what one has learnt.

    What is Thirukkural?

    • The Tirukkuṟaḷ (meaning ‘sacred verses’), or shortly the Kural, is a classic Tamil language text consisting of 1,330 short couplets, or kurals, of seven words each.
    • The text is divided into three books with aphoristic teachings on virtue (aram), wealth (porul) and love (inbam), respectively.
    • Considered one of the greatest works ever written on ethics and morality, it is known for its universality and secular nature.

    Three major parts of the book

    1. Aram : Book of Virtue (Dharma), dealing with moral values of an individual and essentials of yoga philosophy
    2. Porul : Book of Polity (Artha), dealing with socio-economic values, polity, society and administration
    3. Inbam: Book of Love (Kama), dealing with psychological values and love

    Who authored it and when?

    • Its authorship is traditionally attributed to Valluvar, also known in full as Thiruvalluvar.
    • The text has been dated variously from 300 BCE to 5th century CE.
    • The traditional accounts describe it as the last work of the third Sangam, but linguistic analysis suggests a later date of 450 to 500 CE and that it was composed after the Sangam period.

    Cultural significance of Thirukkural

    • The Kural is traditionally praised with epithets and alternative titles, including “the Tamil Veda” and “the Divine Book.”
    • Written on the foundations of ahimsa, it emphasizes non-violence and moral vegetarianism as virtues for an individual.
    • In addition, it highlights truthfulness, self-restraint, gratitude, hospitality, kindness, goodness, duty, giving, and so forth.
    • It covers a wide range of social and political topics such as king, ministers, taxes, justice, forts, war, greatness of army and soldier’s honor.
    • It emphasizes death sentence for the wicked, agriculture, education, abstinence from alcohol and intoxicants.
    • It also includes chapters on friendship, love, sexual unions, and domestic life.

    Read these quotes and bookmark them. They can be used in essays:

    1. Nothing is impossible for those who act after wise counsel and careful thought.
    2. Real kindness seeks no return.
    3. The only gift is giving to the poor; All else is exchange.
    4. Friendship with the wise gets better with time, as a good book gets better with age.
    5. Worthless are those who injure others vengefully, while those who stoically endure are like stored gold.
    6. Among a man’s many good possessions, A good command of speech has no equal. Prosperity and ruin issue from the power of the tongue. Therefore, guard yourself against thoughtless speech.
    7. A fortress is of no use to cowards.
    8. Even the ignorant may appear very worthy, If they keep silent before the learned.

    [pib] Sacred Ensembles of the Hoysalas

    Prelims Only | History | Mains Paper 1: Arts & Culture

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sacred Ensembles of the Hoysalas

    Mains level: Temple architecture of India

    The Hoysala Temples of Belur, Halebid and Somnathapura in Karnataka have been finalized as India’s nomination for consideration as World Heritage for the year 2022-2023.

    Sacred Ensembles of the Hoysalas

    • The sacred ensembles of the Hoysalas are extraordinary expressions of spiritual purpose and vehicles of spiritual practice and attainment.
    • The sacred ensembles of the Hoysalas at Belur and Halebid are the finest, most exquisite, and most representative examples of the artistic genius and cultural accomplishments of the Hoysalas remaining today.

     [I] Belur: Chennakeshava Temple Complex

    • The Chennakeshava temple complex was at the center of the old walled town located on the banks of the Yagachi River.
    • The complex itself was walled in a rectangular campus with four rectilinear streets around it for ritual circumambulation of the deity.
    • Construction of the temple commenced in 1117 AD and took a 103 years to complete.
    • The temple was devoted to Vishnu.
    • The richly sculptured exterior of the temple narrate scenes from the life of Vishnu and his reincarnations and the epics, Ramayana, and Mahabharata.
    • However, some of the representations of Shiva are also included.
    • Consecrated on a sacred site, the temple has remained continuously worshipped since its establishment and remains until today as a site of pilgrimage for Vaishnavites.

    [II] Halebid: Hoysaleshwara Temple

    • At the zenith of the Hoysala empire, the capital was shifted from Belur to Halebid that was then known as Dorasamudhra.
    • The Hoysaleshwara temple at Halebidu is the most exemplary architectural ensemble of the Hoysalas extant today.
    • Built in 1121CE during the reign of the Hoysala King, Vishnuvardhana Hoysaleshwara.
    • The temple, dedicated to Shiva, was sponsored and built by wealthy citizens and merchants of Dorasamudra.
    • The temple is most well-known for the more than 240 wall sculptures that run all along the outer wall.
    • Halebid has a walled complex containing of three Jaina basadi (temples) of the Hoysala period as well as a stepped well.

    [III] Somnathpur: Kesava Temple

    • The Keshava temple at Somanathapura is another magnificent Hoysala monument, perhaps the last.
    • This is a breathtakingly beautiful Trikuta Temple dedicated to Lord Krishna in three forms – Janardhana, Keshava and Venugopala.
    • Unfortunately, the main Keshava idol is missing, and the Janardhana and Venugopala idols are damaged.
    • Still this temple is worth a visit just to soak in the artistry and sheer talent of the sculptors who created this magnificent monument to the Divine.

    Prelims level: PUC Certificate

    Mains level: Not Much

    Delhi govt will soon make PUC certificate mandatory for fuel at filling stations.

    What is PUC Certificate?

    • The PUC certificate is a document that any person driving a motor vehicle can be asked to produce by a police officer in uniform authorized by the state government.
    • These issue certificates if a vehicle is found complying with the prescribed emission norms.
    • Since the Motor Vehicles (Amendment) Act, 2019 came into force, PUC certificate has been made mandatory.
    • A PUC certificate contains information such as the vehicle’s license plate number, PUC test reading, date on which the PUC test was conducted and the expiry date.

    How is a pollution control check carried out?

    • The computerized model for pollution check was developed by the Society of Indian Automobile manufacturers.
    • A gas analyzer is connected to a computer, to which a camera and a printer are attached.
    • The gas analyzer records the emission value and sends it to the computer directly, while the camera captures the license plate of the vehicle.

  • Zoonotic Diseases: Medical Sciences Involved & Preventive Measures

    NeoCov Coronavirus found in Bats

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: NeoCoV

    Mains level: Not Much

    NeoCov coronavirus found in bats may pose threat to humans in the future, scientists caution.

    Coronavirus: A quick backgrounder

    • Coronaviruses are a large family of viruses that are known to infect animals and humans.
    • They are largely categorized into four genera — alpha, beta, gamma, and delta.
    • Broadly speaking, alpha and beta coronaviruses commonly infect mammals such as bats and humans, while Gamma and Delta mainly infect birds.

    Infecting humans: Through ‘Zoonotic Spillover’

    • While animals, including bats, are generally considered as the reservoirs of coronaviruses, rarely spillover events could occur.
    • It is possible for viruses that infect animals to jump to humans, a process which is known as zoonotic spillover.
    • Many major infectious diseases, including COVID-19, is widely thought to be a result of spillover.

    COVID-19 Pandemic

    • SARS-CoV-2, the coronavirus responsible for the COVID-19 pandemic, belongs to the genus of beta coronavirus.
    • It is in fact the 7th type of coronavirus known to infect and cause severe disease in humans.

    How does it affect humans?

    • How a coronavirus latches onto special receptors on host cells depends on a key part of the virus known as its receptor-binding domain.
    • The differences in the receptor-binding domain of coronaviruses are therefore what determine the type of host receptor the virus will use and thus the host that it will be able to infect.
    • There are currently 4 well-characterized receptors for coronaviruses, including ACE2, which is used by SARS-CoV and SARS-CoV-2, and DPP4 used by MERS-CoV.

    What is NeoCoV?

    • NeoCoV is a bat coronavirus that was first identified in 2011.
    • It was identified in a species of bats known as Neoromicia, which is where the name NeoCoV was derived from.
    • Commonly known as aloe bats, this species is distributed in the Afro-Malagasy region.
    • NeoCoV shares an 85% similarity to MERS-CoV in the genome sequence, making it the closest known relative of MERS-CoV.

    Does NeoCoV infect humans and cause high mortality?

    • It is important to note that inherently, NeoCoV cannot interact with human receptors, implying that in its current form the virus cannot infect humans.
    • NeoCoV does not infect humans yet and has thus not caused any deaths.

    What does the preprint say and why is it important?

    • The study reports that despite their similarity, MERS-CoV and NeoCoV use different receptors to infect cells.
    • The bat coronavirus NeoCoV was found to use bat ACE2 receptors for efficiently entering cells.
    • The interaction between NeoCoV and bat ACE2 receptors is different from what is seen in other coronaviruses that utilize ACE2.
    • However, specific mutations artificially created in the receptor-binding domain of NeoCoV can enhance its efficiency to interact with human ACE2 receptors.
    • These mutations have not yet been seen in NeoCov isolates from natural settings.

    Conclusion

    • SARS-CoV-2 is not the first coronavirus to infect humans and cause large disease outbreaks, nor is it likely to be the last.
    • The study highlights that through further adaptation, coronaviruses like NeoCoV or other related viruses could potentially gain the ability to infect humans.

    Way forward

    • To prevent future outbreaks, it will thus be important to monitor this family of viruses for potential zoonosis while continuing research efforts on understanding the complex receptor usage of different coronaviruses.
    • Genomic surveillance of human and animal viruses is, therefore, the key to understanding the spectrum of viruses, and possibly provides early warning to potential spillover events.
