    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Ramanuja, Vishishtadvaita

    Mains level: Not Much

    Work is going apace on the 216-ft tall ‘Statue of Equality’ of the 11th century reformer and Vaishnavite saint, Sri Ramanuja, to be unveiled by PM Modi next month in Hyderabad.

    Statue of Equality

    • The ‘Statue of Equality’, as it is called, is being installed to mark the 1,000th birth anniversary of Sri Ramanuja.
    • It was built of panchaloha, a combination of gold, silver, copper, brass and zinc, by the Aerospun Corporation in China and shipped to India.
    • It is the second largest in the world in sitting position of the saint.
    • The monument will be surrounded by 108 “Divya Desams” of Sri Vaishnavite tradition (model temples) like Tirumala, Srirangam, Kanchi, Ahobhilam, Badrinath, Muktinath, Ayodhya, Brindavan, Kumbakonam and others.
    • The idols of deities and structures were constructed in the shape at the existing temples.

    Who was Sri Ramanuja?

    Ramanuja or Ramanujacharya (1017–1137 CE) was a philosopher, Hindu theologian, social reformer, and one of the most important exponents of Sri Vaishnavism tradition within Hinduism.

    • His philosophical foundations for devotionalism were influential to the Bhakti movement.

    His works

    • Ramanuja’s philosophical foundation was qualified monism and is called Vishishtadvaita in the Hindu tradition.
    • His ideas are one of three subschools in Vedanta, the other two are known as Adi Shankara’s Advaita (absolute monism) and Madhvacharya’s Dvaita (dualism)
    • Important writings include:
    1. Vedarthasangraha (literally, “Summary of the Vedas meaning”),
    2. Sri Bhashya (a review and commentary on the Brahma Sutras),
    3. Bhagavad Gita Bhashya (a review and commentary on the Bhagavad Gita), and
    • The minor works titled Vedantapida, Vedantasara, Gadya Trayam (which is a compilation of three texts called the Saranagati Gadyam, Sriranga Gadyam and the Srivaikunta Gadyam), and Nitya Grantham.

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

    Declaration on Forests and Land Use

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Declaration on Forests and Land Use

    Mains level: Not Much

    At COP-26 in Glasgow, countries got together to sign the Declaration on Forests and Land Use (or the Deforestation Declaration). However, India was among the few countries that did not sign the declaration.

    What is this Deforestation Declaration?

    • It was signed by 142 countries, which represented over 90 percent of forests across the world.
    • The declaration commits to halt and reverse forest loss and land degradation by 2030 while delivering sustainable development and promoting an inclusive rural transformation.
    • The signatories committed $19 billion in private and public funds to this end.

    Why did India abstain from joining?

    • India had concerns about the linkage the declaration makes between deforestation, infrastructure development and trade.
    • Any commitment to the environment and climate change should not involve any reference to trade, cited India.
    • Analysts in India have linked the decision to a proposed amendment to the Forest Conservation Act 1980 that would ease the clearances presently required for acquiring forest land for new infrastructure projects.

    India abstained from many things

    • A look at India’s positions on some other recent critical pledges and decisions related to climate change reveals a clear pattern of objections or absence.
    • At CoP26, India was not part of the dialogue on Forests, Agriculture and Commodity Trade (FACT).
    • FACT, which is supported by 28 countries seeks to encourage “sustainable development and trade of agricultural commodities while protecting and managing sustainably forests and other critical ecosystems”.
    • India also voted against a recent draft resolution to allow for discussions related to climate change and its impact on international peace and security to be taken up at the UNSC.

    Why should India join this declaration?

    • Broadly speaking, all of India’s objections are based on procedural issues at multilateral fora.
    • Although justifiable on paper, these objections seem blind to the diverse ways in which climate change is linked to global trade, deforestation, agriculture, and international peace, among other issues.
    • For context, consider India’s palm oil trade. India is the largest importer of crude palm oil in the world.
    • Palm oil cultivation, covering roughly 16 million acres of land in Indonesia and Malaysia, has been the biggest driver of deforestation in the two countries.

    Why 5G roll-outs are disrupting flights to the US?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Read the attached story

    Mains level: Hurdles in 5G Rollout

    Air India said Boeing had cleared its B777 aircraft for flights to the US following concerns that the 5G roll-out there could interfere with critical aircraft functions.

    What is 5G Technology?

    • 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
    • It’s a unified platform which is much more capable than previous mobile services with more capacity, lower latency, faster data delivery rate and better utilization of spectrum.

    How can 5G affect flight safety?

    • Airlines take off and land using auto-pilot systems, which use data from radar altimeters to determine the altitude of the aircraft.
    • Altimeters emit radio waves at 4.2-4.3 Gigahertz (GHz) frequency, which could interfere with a 5G band called C-Band, which lies between 3.7-4.4 GHz.
    • This interference can mess up the data. That’s the safety concern. Radio altimeters are used at airports and other low-altitude locations.
    • A different kind of altimeter, called pressure altimeter, is used for high altitude areas.
    • Not using auto-pilot would lead to more fuel consumption and higher costs for airlines.

    What happens to Air India’s operations?

    • While scheduled international flights, to and from India, remain suspended due to the pandemic, Air India operates flights to the US under an air bubble agreement.
    • These routes are served by the airline’s wide-body fleet of Boeing 777 and Boeing 787 planes.
    • The roll out of 5G is expected to primarily impact the operations of Boeing 777 and 747.

    Can this impact India’s 5G roll-out?

    • India’s 5G auctions are expected to include spectrum bands of 3.3GHz -3.6GHz, which means the C-Band may not be operational, at least in the near future.
    • Plus, aircraft equipment is manufactured globally, with certain standards.
    • The FAA tests will likely lead to standards for altimeters and applied internationally.
    • For aircraft makers, altimeters are key equipment. But they’re bought off-the-rack instead being designed in-house.
    • Once a standard is known, it can be implemented in all aircraft.

    What is Antimicrobial Resistance (AMR)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Anti-Microbial Resistance

    Mains level: Overdose of anti-biotics

    The Global Research on Antimicrobial Resistance (GRAM) report published in The Lancet provides the most comprehensive estimate of the global impact of Antimicrobial Resistance (AMR) so far.

    What is AMR?

    • Antimicrobial resistance (AMR or AR) is the ability of a microbe to resist the effects of medication that once could successfully treat the microbe
    • Antibiotic resistance occurs naturally, but misuse of antibiotics in humans and animals is accelerating the process.
    • A growing number of infections – such as pneumonia, tuberculosis, gonorrhoea, and salmonellosis – are becoming harder to treat as the antibiotics used to treat them become less effective.
    • It leads to higher medical costs, prolonged hospital stays, and increased mortality.

    How does it occur?

    • Antibiotics are medicines used to prevent and treat bacterial infections.
    • Antibiotic resistance occurs when bacteria change in response to the use of these medicines.
    • Bacteria, not humans or animals, become antibiotic-resistant.
    • These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria.

    What did the GRAM report find?

    • AMR is a leading cause of death globally, higher than HIV/AIDS or malaria.
    • As many as 4.95 million deaths may be associated with bacterial AMR in 2019.
    • Lower respiratory tract infections accounted for more than 1.5 million deaths associated with resistance in 2019, making it the most common infectious syndrome.

    The six leading pathogens for deaths associated with resistance were:

    1. Escherichia coli (E. Coli)
    2. Staphylococcus aureus
    3. Klebsiella pneumonia
    4. Streptococcus pneumonia
    5. Acinetobacter baumannii
    6. Pseudomonas aeruginosa

    What are the implications of this study?

    • Common infections such as lower respiratory tract infections, bloodstream infections, and intra-abdominal infections are now killing hundreds of thousands of people every.
    • This includes historically treatable illnesses, such as pneumonia, hospital-acquired infections, and foodborne ailments.

    Way forward

    • Doctors recommend greater action to monitor and control infections, globally, nationally and within individual hospitals.
    • Access to vaccines, clean water and sanitation ought to be expanded.
    • The use of antibiotics unrelated to treating human disease, such as in food and animal production must be “optimised” and finally they recommend being “more thoughtful”.

    Telangana’s Tribal Fair: Sammakka-Sarakka Jatara

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Sammakka-Sarakka Jatara

    Mains level: Not Much

    Medaram, a tiny village in Telangana’s tribal heartland of Mulugu district, is getting ready to host the Sammakka-Sarakka jatara, billed as the country’s biggest tribal fair.

    Sammakka-Sarakka Jatara

    • The mega four-day jatara, scheduled to begin on February 16 in Medaram. It takes place once in two years.
    • It is perhaps the only tribal fair devoted to pay tribute to tribal warriors who made supreme sacrifices defending the rights of aboriginal tribal people.
    • It symbolises the traditions and heritage of the Koya tribal people.
    • The sacred site in Medaram and its surrounding Jampanna vagu, named after tribal martyr Jampanna, son of Sammakka, comes alive with lakhs of devotees during the four-day jatara.

    Why do tribals come to Medaram?

    • This festival commemorates a tribal revolt led by Sammakka and Saralamma, a mother-daughter duo, against levy of taxes on tribal people during drought conditions by the then Kakatiya rulers in the 12th century.
    • Tribals (and others) flock to Medaram during the jatara not just from Telangana and Andhra Pradesh but also from as far as Madhya Pradesh, Jharkhand, Chhattisgarh and Maharashtra.
    • Sammakka and Saralamma are revered by devotees as tribal goddesses, and devotees make offerings to propitiate them to bestow health and wealth.
    • All the rituals at the jatara site are held in tune with tribal traditions under the aegis of tribal priests.

    Features of the celebrations

    • One of the striking features of the tribal fair is the offering of jaggery to the tribal goddess at the altars (bamboo poles).
    • It encompasses common features of tribal fairs – die-hard devotees going into a trance, the sacrifice of fowls and goats, besides pulsating traditional drum beats accompanying folk songs.

    About Tamiraparani River

    • The Thamirabarani or Tamraparni or Porunai is a perennial river that originates from the Agastyarkoodam peak of the Pothigai hills of the Western Ghats.
    • It flows through the Tirunelveli and Thoothukudi districts of the Tamil Nadu state of southern India into the Gulf of Mannar.
    • It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka.
    • The old Tamil name of the river is Porunai.

    Its history

    • Its many name derivations of Tan Porunai include Tampraparani, Tamirabarni, Tamiravaruni.
    • Tan Porunai nathi finds mention by classical Tamil poets in ancient Sangam Tamil literature Purananuru.
    • Recognised as a holy river in Sanskrit literature Puranas, Mahabharata and Ramayana, the river was famed in the Early Pandyan Kingdom for its pearl and conch fisheries and trade.
    • The movement of people, including the faithful, trade merchants and toddy tapers from Tamraparni river to northwestern Sri Lanka led to the shared appellation of the name for the closely connected region.
    • One important historical document on the river is the treatise Tamraparni Mahatmyam.
    • It has many ancient temples along its banks. A hamlet known as Appankoil is located on the northern side of the river.

    Back2Basics: Keeladi Civilization

    • The Keeladi tale began to unravel in March 2015 when first round of excavation was undertaken by the Archaeological Survey of India (ASI).
    • It unearthed antiquities providing crucial evidence to understanding the missing links of the Iron Age [12th century BCE to 6th century BCE] to the Early Historic Period [6th century BCE to 4th century BCE].
    • Further excavations threw up strong clues about the existence of a Tamil Civilization that had trade links with other regions in the country and abroad.
    • This civilization has been described by Tamil poets belonging to the Sangam period.
    • Results of carbon dating of a few artifacts traced their existence to 2nd century BCE (the Sangam period).

    Key findings in excavations

    • These included brick structures, terracotta ring wells, fallen roofing with tiles, golden ornaments, broken parts of copper objects, iron implements, terracotta chess pieces, ear ornaments, spindle whorls, figurines.

    Nusantara City: New Capital of Indonesia

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Nusantara

    Mains level: NA

    Indonesia passed a bill replacing its capital Jakarta with East Kalimantan, situated to the east of Borneo island. The new capital city of the country will be called Nusantara.

    About Nusantara

    • The New State Capital Law Bill has been drafted by a special committee set up by Widodo’s government and makes Nusantara, also called IKN, the capital of the Republic of Indonesia.
    • The transfer of the status of Jakarta as Indonesia’s capital to Nusantara, where 256,142 hectares of land has been set aside for the project, will take place in the “first semester” of 2024.
    • East Kalimantan, where the new capital will be, as per the bill is said to have a world-city vision.
    • It will be designed and managed with the objective of becoming a sustainable city in the world.

    Why is Indonesia changing its capital city?

    • The new location is very strategic – it’s in the centre of Indonesia and close to urban areas.
    • The burden Jakarta is holding right now is too heavy as the centre of governance, business, finance, trade and services.
    • Jakarta is also infamous for being the worlds’ first sinking capital city due to rising sea levels.
    • The city’s pollution levels are so bad that it has been ranking as one of the most polluted cities in the world for years.
    • Another important reason to shift the capital from Java island to Borneo island has been the growing inequality – financial and otherwise.

    Where is East Kalimantan?

    • East Kalimantan is 2,300 kilometres from Jakarta on the eastern side of Borneo island, shared by Indonesia, Malaysia and Brunei.
    • The new capital will be located in the North Penajam Paser and Kutai Kartanegara regions.
    • East Kalimantan is an area with immense water resources and habitable terrain.
    • East Kalimantan is rich in flora and fauna.

    Why Nusantara?

    • Nusantara is an old Javanese term that means ‘archipelago’.
    • Nusantara has historical, sociological, and philosophical aspects attached to the name.
    • The name would represent Indonesia as a whole and would show the potential of the nation.

    What are the other countries that have changed capitals?

    • Indonesia is not the first country to change its capital city.
    • There has been a long list of countries that have changed their capitals for various reasons. Brazil changed its capital city from Rio De Janerio to Brasilia, a more centrally-located city, in 1960.
    • In 1991, Nigeria hanged the country’s capital from Lagos to Abuja.
    • Kazakhstan moved its capital city from Almaty, which is still its commercial centre, to Nur-Sultan in 1997.
    • Myanmar changed its capital from Rangoon to Naypyidaw in 2005.

  • Air Pollution

    What are Smog Towers?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Smog Tower

    Mains level: Effectiveness of smog towers

    Some researchers in New Delhi have observed paradoxical phenomena near the smog towers. The air closest to the tower should be cleanest, but the device recorded the opposite in several instances.

    What are Smog Towers?

    • Smog towers are structures designed to work as large-scale air purifiers. They are fitted with multiple layers of air filters and fans at the base to suck the air.
    • After the polluted air enters the smog tower, it is purified by multiple layers before being re-circulated into the atmosphere.

    Structure of the Delhi smog tower

    • The structure is 24 m high, about as much as an 8-storey building — an 18-metre concrete tower, topped by a 6-metre-high canopy. At its base are 40 fans, 10 on each side.
    • Each fan can discharge 25 cubic metres per second of air, adding up to 1,000 cubic metres per second for the tower as a whole. Inside the tower in two layers are 5,000 filters.
    • The filters and fans have been imported from the United States.

    How does it work?

    • The tower uses a ‘downdraft air cleaning system’ developed by the University of Minnesota.
    • Polluted air is sucked in at a height of 24 m, and filtered air is released at the bottom of the tower, at a height of about 10 m from the ground.
    • When the fans at the bottom of the tower operate, the negative pressure created sucks in air from the top.
    • The ‘macro’ layer in the filter traps particles of 10 microns and larger, while the ‘micro’ layer filters smaller particles of around 0.3 microns.
    • The downdraft method is different from the system used in China, where a tower uses an ‘updraft’ system — air is sucked in from near the ground, and is propelled upwards by heating and convection.
    • Filtered air is released at the top of the tower.

    Likely impact

    • Computational fluid dynamics modelling suggests the tower could have an impact on the air quality up to 1 km from the tower.
    • The actual impact will also determine how the tower functions under different weather conditions, and how levels of PM2.5 vary with the flow of air.

    Issues with smog towers

    • Many experts say that the smog towers are not a viable method to clean city’s air.
    • The government had talked about 80% pollution reduction at inlet and outlet of the tower but never mentioned about the effect of distance from the tower.
    • Instead of spending â‚č40 crore on two towers, the government could have spent the funds on several other options such as replacing the small and polluting industrial boilers or chimneys etc.
