From UPSC perspective, the following things are important :
Prelims level: Prithviraj Chauhan
Mains level: NA
There is controversy around a new film where some communities of Rajasthan are laying claim over the 12th century emperor Prithviraj Chauhan.
Prithviraj Chauhan
- Prithviraj Chauhan (1177–1192 CE) popularly known as a king from the Chauhan (Chahamana) dynasty who ruled the territory of Sapadalaksha, with his capital at Ajmer in present-day Rajasthan.
- Ascending the throne as a minor in 1177 CE, Prithviraj inherited a kingdom which stretched from Thanesar in the north to Jahazpur (Mewar) in the south.
His legend
- He aimed to expand by military actions against neighbouring kingdoms, most notably defeating the Chandela’s.
- Prithviraj unified several Rajput clans and defeated the Ghurid army led by Muhammad Ghori near Taraori in 1191 AD.
- However, in 1192 CE, Ghori returned with an army of Turkish mounted archers and defeated the Rajput army on the same battlefield.
- Prithviraj fled the battlefield, but was captured near Sirsa and executed.
- His defeat at Tarain is seen as a landmark event in the Islamic conquest of India, and has been described in several semi-legendary accounts, most notably the Prithviraj Raso.
Prithviraj in literary works
- The image of Prithviraj as a fearless and skilled warrior that is now etched in the folk imagination can be traced back to his depiction in ‘Prithviraj Raso’.
- This was a poem in Brajbhasha attributed to Chand Bardai, which is thought to have been composed in the 16th century.
- James Mill’s ‘The History of British India’ (1817) categorized Indian history into the Hindu, Muhammadan and British periods.
- In this formulation, Prithviraj Chauhan would be the last ruler of ‘Hindu’ India.
Why is he being revived?
- To a vocal section of the Hindu right, Prithviraj Chauhan appears as “the last Hindu emperor” of India who made a valiant attempt to stop the radical invaders.
- In the popular imagination, he is the heroic figure who symbolises the exalted ideals of patriotism and national pride.
- However the historical evidence demonstrates rather different ways in which Prithviraj has been seen over the ages.

From UPSC perspective, the following things are important :
Prelims level: Storage gain in wheat
Mains level: NA
Punjab’s state procurement agencies (SPAs) are seeking a waiver of ‘storage gain’.
What is ‘storage gain’ in wheat?
- Wheat, considered a ‘living grain’, tends to gain some weight during storage.
- This is known as ‘storage gain’ and it mostly happens due to absorption of moisture.
- There are three parts of the grain — bran (outer layer rich in fibre), germ (inner layer rich in nutrients) and endosperm (bulk of the kernel which contains minerals and vitamins).
- The moisture is mostly absorbed by the endosperm.
Who compensates whom for ‘storage gain’?
- State procurement agencies, which purchase and store wheat at their facilities, are required to give one kg wheat extra per quintal to the Food Corporation of India (FCI).
- While 20% of wheat, procured by the FCI and the SPAs, is moved immediately after procurement.
- It is usually on the remaining 80%, which is moved out after July 1 every year that storage gain has to be accounted for due to longer storage duration.

From UPSC perspective, the following things are important :
Prelims level: Project Wardec
Mains level: Not Much
The Army Training Command signed a memorandum of understanding (MoU) with Gandhinagar-based Rashtriya Raksha University (RRU) to develop a ‘Wargame Research and Development Centre (WARDEC)’ in New Delhi.
What is Project WARDEC?
- The project ‘WARDEC’ will be a first-of-its-kind simulation-based training centre in India that will use artificial intelligence (AI) to design virtual reality war-games.
- The Wargame Research and Development Centre will be used by the Army to train its soldiers and test their strategies through “metaverse-enabled gameplay”.
- The wargame models will be designed to prepare for wars as well as counter-terror and counter-insurgency operations.
Where will the centre come up and when?
- The centre will come up in a military zone in New Delhi, confirmed RRU officials privy to the development.
- The RRU will join hands with Tech Mahindra to develop the centre in the coming three to four months.
- The RRU, an institute under the Ministry of Home Affairs (MHA), specialises in national security and policing.
- Located in Gandhinagar’s Lavad village, it is an “institute of national importance” – a status granted to it by an Act of Parliament.
How will these simulation exercises play out?
- Soldiers will test their skills in the metaverse where their surroundings will be simulated using a combination of virtual reality (VR) and augmented reality (AR).
- In metaverse, the players will get a realistic experience of the actual situation.
- If a weapon weighing 5 kg drops or the air pressure falls, they will feel it like anyone would in a live situation, real-time.
- The game would play out player versus player, player versus computer or even computer versus computer.
How will the centre help the Army?
- The Army intends to use the war-game centre to train its officers in military strategies.
- Indian Army will provide data to set the backdrop of the gameplay, so that participants get a realistic experience.
- In Army, it is often said that the enemy can ambush you from 361 directions, where 360 sides are around the soldier, and one is above in case there is an airdrop.
- So, wargame simulation helps the Army think of all possible scenarios.
What promise does AI-based wargame simulation hold?
- Apart from the armed forces, the BSF, CRPF, CISF, ITBP and SSB can also use the metaverse-enabled simulation exercises for better training.
- The use of AI can provide a totally immersive training experience as it can simulate a battlefield close to reality and map several eventualities in the probable event of a war.
How many countries use such wargaming drills?
- Since the 9/11 attacks, use of information technology-enabled wargaming is preferred by several countries like the US, Israel, the UK to prepare for possibilities in case of terror attacks or war.
- In March 2014, several world leaders, including former German chancellor Angela Merkel, former US president Barack Obama and Chinese president Xi Jinping had played a war simulation game.
- It was during the Hague Summit about how to react in case of a nuclear attack.
- In that case, the target of the nuclear attack was a fictional country named Brinia.

From UPSC perspective, the following things are important :
Prelims level: Sudden Infant Death Syndrome (SIDS)
Mains level: Not Much
A team of scientists from Australia have found that babies at risk of the mysterious Sudden Infant Death Syndrome, or SIDS, generally have low levels of an enzyme called butyrylcholinesterase (BChE) in their blood.
What is SIDS?
- Sudden Infant Death Syndrome refers to the sudden and unexpected death of an otherwise healthy infant under the age of one, generally while they are sleeping.
- Most SIDS-related deaths occur in infants between the age of 1-4 months.
- According to the NHS website, parents can reduce the risk of SIDS by not smoking while pregnant or after the baby is born and ensuring that the baby is placed on their back when they sleep.
- Some health experts have said that it is associated with issues in the part of an infant’s brain that controls breathing and waking up.
Prevalence of SIDS
- SIDS, also known as ‘cot death’, has claimed the lives of thousands of children across the West.
- US estimates that about 3,400 babies die suddenly and unexpectedly every year.
- Meanwhile, the United Kingdom reports about 200 such deaths annually.
What does the new study say?
- The study assessed whether there was something inherently different in babies that succumbed to SIDS.
- The researchers compared dried blood samples from 655 healthy babies, 26 babies who died due to SIDS and 41 babies who died of other causes.
- The team found that around nine of ten babies who died from SIDS had lower levels of BChE enzymes than the babies in the other two groups.
What is the BChE (Butyrylcholinesterase) enzyme responsible for?
- These enzymes are responsible for sending out signals that make a baby wake up, turn her head, or gasp for breath.
- It is part of the autonomic system, and controls function like blood pressure and breathing.

From UPSC perspective, the following things are important :
Prelims level: Places associated with Buddha
Mains level: Buddhist architecture
Prime Minister in Lumbini, on the occasion of Buddha Purnima, said that his birthplace Vadnagar in Gujarat’s Mehsana district had been a great centre for Buddhist learning centuries ago.
Vadnagar’s ties with Buddhism
- In 2014, the excavation work has brought up Buddhist relics and around 20,000 artefacts, some dating back to the 2nd century.
- Among these are an elliptical structure and a circular stupa along with a square memorial stupa of 2×2 metres and 130 centimetres in height with a wall enclosure.
- It is like a platform which has a chamber in the centre that resembles a pradakshina path.
- Further, bowls said to be used by monks have been found during the excavations, which have a terracotta sealing with inscriptions of namassarvagyaya and a face-shaped pendant with tritatva symbol.
- Sacred relics of the Buddha were even found in Devni Mori in Aravalli district of Gujarat.
In travellers record
- Vadnagar is mentioned often in the Puranas and even in the travelogue of the great Chinese traveler, Hiuen Tsang (7th century), as a rich and flourishing town.
- He is believed to have visited the state in 641 AD.
- It adds how some of the names attributed to Vadnagar in history are Chamatkarpur, Anandpur, Snehpur and Vimalpur.
- It also had snippets about other Buddhist heritage sites in Gujarat, such as Junagadh, Kutch and Bharuch.

From UPSC perspective, the following things are important :
Prelims level: Repo Rate
Mains level: Inflation targetting by MPC
Earlier this month, the RBI, in a surprise move decided unanimously to raise the “policy repo rate by 40 basis points to 4.40%, with immediate effect”.
What is the Repo Rate?
- The repo rate is one of several direct and indirect instruments that are used by the RBI for implementing monetary policy.
- Specifically, the RBI defines the repo rate as the fixed interest rate at which it provides overnight liquidity to banks against the collateral of government and other approved securities under the liquidity adjustment facility (LAF).
- In other words, when banks have short-term requirements for funds, they can place government securities that they hold with the central bank and borrow money against these securities at the repo rate.
- Since this is the rate of interest that the RBI charges commercial banks such as SBI and ICICI Bank when it lends them money, it serves as a key benchmark for the lenders to in turn price the loans they offer to their borrowers.
Why is the repo rate such a crucial monetary tool?
- According to Investopedia, when government central banks repurchase securities from commercial lenders, they do so at a discounted rate that is known as the repo rate.
- The repo rate system allows central banks to control the money supply within economies by increasing or decreasing the availability of funds.
How does the repo rate work?
- Besides the direct loan pricing relationship, the repo rate also functions as a monetary tool by helping to regulate the availability of liquidity or funds in the banking system.
- For instance, when the repo rate is decreased, banks may find an incentive to sell securities back to the government in return for cash.
- This increases the money supply available to the general economy.
- Conversely, when the repo rate is increased, lenders would end up thinking twice before borrowing from the central bank at the repo window thus, reducing the availability of money supply in the economy.
- Since inflation is caused by more money chasing the same quantity of goods and services available in an economy, central banks tend to target regulation of money supply as a means to slow inflation.
What impact can a repo rate change have on inflation?
- Inflation can broadly be: mainly demand driven price gains, or a result of supply side factors.
- This in turn push up the costs of inputs used by producers of goods and providers of services.
- It is thus spurring inflation, or most often caused by a combination of both demand and supply side pressures.
- Changes to the repo rate to influence interest rates and the availability of money supply primarily work only on the demand side.
- It makes credit more expensive and savings more attractive and therefore dissuading consumption.
- However, they do little to address the supply side factors, be it the high price of commodities such as crude oil or metals or imported food items such as edible oils.
Try this PYQ:
Q.If the RBI decides to adopt an expansionist monetary policy, which of the following would it not do?
- Cut and optimize the Statutory Liquidity Ratio
- Increase the Marginal Standing Facility Rate
- Cut the Bank Rate and Repo Rate

(a) 1 and 2 only

From UPSC perspective, the following things are important :
Prelims level: mRNA, RNA granules
Mains level: Not Much
Researchers at IISc Bangalore have identified a protein in yeast cells that dissolves RNA-protein complexes, also known as RNA granules.
What is mRNA?
- Messenger RNA (mRNA) is a single-stranded RNA (Ribo Nucleic Acid) molecule that is complementary to one of the DNA strands of a gene.
- The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
- During protein synthesis, an organelle called a ribosome moves along the mRNA, reads its base sequence, and uses the genetic code to translate each three-base triplet, or codon, into its corresponding amino acid.
What are RNA granules?
- Inside the cytoplasm of any cell there are structures made of messenger RNA (mRNA) and proteins known as RNA granules.
- Unlike other structures in the cell (such as mitochondria), the RNA granules are not covered and confined by a membrane.
- This makes them highly dynamic in nature, thereby allowing them to constantly exchange components with the surrounding.
- RNA granules are present in the cytoplasm at low numbers under normal conditions but increase in number and size under stressful conditions including diseases.
Why are they unique?
- A defining feature which does not change from one organism to another (conserved) of the RNA granule protein components is the presence of stretches containing repeats of certain amino acids.
- Such stretches are referred to as low complexity regions.
- Repeats of arginine (R), glycine (G) and glycine (G) — known as RGG — are an example of low complexity sequence.
Functions of RNA granules
- Messenger RNAs are converted to proteins (building blocks of the cell) by the process of translation.
- RNA granules determine messenger RNA (mRNA) fate by deciding when and how much protein would be produced from mRNA.
- Protein synthesis is a multi-step and energy-expensive process.
- Therefore, a common strategy used by cells when it encounters unfavorable conditions is to shut down protein production and conserve energy to deal with a stressful situation.
- RNA granules help in the process of shutting down protein production.
- Some RNA granule types (such as Processing bodies or P-bodies) not only regulate protein production but also accomplish degradation and elimination of the mRNAs, which in turn helps in reducing protein production.
What is the recent study?
- Researchers concluded that low complexity sequences which normally promote granule formation, in this case promote the disintegration of RNA granules in yeast cells.
- They observed that the identified protein Sbp1 is specific for dissolving P-bodies and not stress granules which are related RNA granule type also present in the cytoplasm.
Significance of the study
- This study has highlighted the potential of amino acid repeats (RGG) as a therapeutic intervention.
- The study may help analyze the effect of repeat sequences in genetically engineered mice that accumulate insoluble pathological aggregates in brain cells.
- This could possibly help in treating neurodegenerative disorders such as Alzheimer’s disease.

From UPSC perspective, the following things are important :
Prelims level: Iron Age
Mains level: Ancient Indian Civilizations
Carbon dating of excavated finds in Tamil Nadu pushes evidence of iron being used in India back to 4,200 years ago, the Tamil Nadu government announced this week on the basis of an archaeological report.
What is the news?
- Before this, the earliest evidence of iron use was from 1900-2000 BCE for the country, and from 1500 BCE for Tamil Nadu.
- The latest evidence dates the findings from Tamil Nadu to 2172 BCE! Much older.
- The results of dating, used accelerator mass spectroscopy.
Where were these objects found?
- The excavations are from Mayiladumparai near Krishnagiri in Tamil Nadu, about 100 km south of Bengaluru.
- Mayiladumparai is an important site with cultural material dating back between the Microlithic (30,000 BCE) and Early Historic (600 BCE) ages.
- The site is situated in the midst of several archaeological sites such as Togarapalli, Gangavaram, Sandur, Vedarthattakkal, Guttur, Gidlur, Sappamutlu and Kappalavadi.
Outcome: Varying span of Iron Age
- The dates when humans entered the Iron Age vary from one region of the world to another.
- In India, too, the date has been revised with successive findings over the decades.
When the Iron Age is considered in India?
- In 1979, use of iron was traced to 1300 BCE at Ahar in Rajasthan. This is what we have been reading in NCERTs.
- Later, samples at Bukkasagara in Karnataka, indicating iron production, were dated back to 1530 BCE.
- The date was subsequently pushed back to 1700-1800 BCE with excavations finding evidence of iron smelting at Raipura in the Mid-Ganga valley.
- It was then to 1900-2000 BCE based on investigations in sites at Malhar near Varanasi and Brahmagiri in North Karnataka.
- A series of dating results on finds from various parts in India have shown evidence of iron-ore technology before 1800 BCE.
- Before the latest discovery, the earliest evidence of iron use for Tamil Nadu was from Thelunganur and Mangadu near Mettur, dating back to 1500 BCE.
Historical significance
- Iron is not known to have been used in the Indus Valley, from where the use of copper in India is said to have originated (1500 BCE).
- But non-availability of copper for technological and mass exploitation forced other regions to remain in the Stone Age.
- When iron technology was invented, it led to the production of agricultural tools and weapons, leading to production required for a civilisation ahead of economic and cultural progress.
- While useful tools were made out of copper, these were brittle and not as strong as iron tools would be.
- With the latest evidence tracing our Iron Age to 2000 BCE from 1500 BC, we can assume that our cultural seeds were laid in 2000 BCE.
- And the benefit of socio-economic changes and massive production triggered by the iron technology gave its first fruit around 600 BCE — the Tamil Brahmi scripts.
Culture and politics
- The Tamil Brahmi scripts were once believed to have originated around 300 BCE, until a landmark finding in 2019 pushed the date back to 600 BCE.
- This dating narrowed the gap between the Indus Valley civilisation and Tamilagam/South India’s Sangam Age.
- This, and the latest findings, are politically significant.
- The dating of the scripts, based on excavations from sites including Keeladi near Madurai, became controversial when the ASI did not go for advanced carbon dating tests.

Prelims level: INSACOG
Mains level: NA
The PM has announced that the Indian SARS-CoV-2 Genomics Consortium (INSACOG) would be extended to India’s neighbouring countries.
What is INSACOG?
- INSACOG was established in December 2020 as a joint initiative of the Union Health Ministry of Health and Department of Biotechnology (DBT).
- It aims to expand the whole-genome sequencing of SARS-CoV-2, the coronavirus that causes the Covid-19 disease, across India with the aim of understanding how the virus spreads and evolves.
- It functions under the Ministry of Science and Technology with the Council for Scientific & Industrial Research (CSIR) and Indian Council of Medical Research (ICMR).
Composition of INSACOG
- INSACOG started out with the participation of 10 national research laboratories of the central government, and gradually expanded to a network of 38 labs.
- It now includes private labs operating on a hub-and-spoke model.
- These works to monitor genomic variations in SARS-CoV-2 by a sentinel sequencing effort which is facilitated by the National Centre for Disease Control (NCDC).
- It now involves the Central Surveillance Unit (CSU) under the central government’s Integrated Disease Surveillance Programme (IDSP).
Working of the INSACOG
- The data from the genome sequencing laboratories is analysed as per the field data trends to study the linkages, if any, between the genomic variants and epidemiological trends.
- INSACOG helps to understand super spreader events and outbreaks, and strengthen public health interventions across the country to help break chains of transmission.
- Linking this data with IDSP data and the patient’s symptoms helps to better understand viral infection dynamics, and trends of morbidity and mortality.
- The data can be linked with host genomics, immunology, clinical outcomes, and risk factors for a more comprehensive outlook.
- Sequencing assumes added significance as the incidence of reinfections and vaccine breakthroughs increases.

Prelims level: India Hypertension Control Initiative (IHCI)
Mains level: Non-communicable diseases burden on India
A project called the India Hypertension Control Initiative (IHCI) finds that nearly 23% out of 2.1 million Indians have uncontrolled blood pressure.
What is the IHCI?
- Recognizing that hypertension is a serious, and growing, health issue in India, the Health Ministry, the ICMR, State Governments, and WHO-India began a five-year initiative to monitor and treat hypertension.
- The programme was launched in November 2017.
- In the first year, IHCI covered 26 districts across five States — Punjab, Kerala, Madhya Pradesh, Telangana, and Maharashtra.
- By December 2020, IHCI was expanded to 52 districts across ten States — Andhra Pradesh (1), Chhattisgarh (2), Karnataka (2), Kerala (4), Madhya Pradesh (6), Maharashtra (13), Punjab (5), Tamil Nadu (1), Telangana (13) and West Bengal (5).
What is Hypertension?
- Hypertension is defined as having systolic blood pressure level greater than or equal to 140 mmHg or diastolic blood pressure level greater than or equal to 90 mmHg.
- The definition also assumes taking anti-hypertensive medication to lower his/her blood pressure.
Why need IHCI?
- India has committed to a “25 by 25” goal, which aims to reduce premature mortality due to non-communicable diseases (NCDs) by 25% by 2025.
- To achieve India’s target of a 25%, approximately 4.5 crore additional people with hypertension need to get their BP under control by 2025.
What has the IHCI found so far?
- Its most important discovery so far is that nearly one-fourth of (23%) patients under the programme had uncontrolled blood pressure, and 27% did not return for a follow-up in the first quarter of 2021.
- There were an estimated 20 crore adults with hypertension in the country.
- There weren’t enough validated high-quality digital blood pressure monitors in several health facilities, which affected accuracy of hypertension diagnosis.
How prevalent is the problem of hypertension?
- About one-fourth of women and men aged 40 to 49 years have hypertension.
- Southern States have a higher prevalence of hypertension than the national average, according to the latest edition of the National Family Health Survey.
- While 21.3% of women and 24% of men aged above 15 have hypertension in the country, the prevalence is the highest in Kerala where 32.8% men and 30.9% women have been diagnosed with hypertension.
- Kerala is followed by Telangana where the prevalence is 31.4% in men and 26.1% in women.

Mains level: Tax evasion
The government has made requirement of a Permanent Account Number (PAN) or Aadhaar number for depositing or withdrawing Rs 20 lakh or more in a financial year or for opening a current account mandatory.
Regulating high-value transactions
- The Central Board of Direct Taxes, in a notification, said furnishing PAN or biometric Aadhaar will be mandatory for such high-value cash deposits or withdrawals from banks in a financial year.
- The same will be applied for opening of a current account or cash credit account with a bank or post office.
- Banks, post offices and co-operative societies would be required to report the transactions of deposits and withdrawals aggregating to Rs 20 lakh or more in a financial year.
- As of now, PAN is required to be furnished for cash deposits of Rs 50,000 or more in a day.
- With these rules, a threshold of Rs 20 lakh has been defined for the full financial year.
How will this help tax department?
- This move will help the government in tracing the movement of cash in the financial system.
- It is expected to help the income tax department monitor deposits/withdrawals where tax would not be getting paid by the individual otherwise on his or her income.
Why PAN-Aadhaar interoperability?
- The PAN-Aadhaar interoperability will help banks to record details for those who don’t have PAN.
- The interchangeable provision in the rules would allow a bank or financial institution to ask for Aadhaar in case an individual states that he or she doesn’t have PAN.
- The Finance Act, 2019, has provided for the interchangeability of PAN with Aadhaar.
- It has been provided that every person who is required to furnish or intimate or quote his PAN under the Income-tax Act.
- Those who, has not been allotted a PAN but possesses the Aadhaar number, may furnish or intimate or quote his Aadhaar in lieu of PAN.

- Green manures are crops grown specifically for maintaining soil fertility and structure.
- It is done by leaving uprooted or sown crops parts, allowing them to wither onto the field and serve as mulch and soil fertilizers.
- They are normally incorporated back into the soil, either directly, or after removal and composting.
- There are three main varieties of green manure, including
- Dhaincha
- Cowpea
- Sunhemp
- Also some crops such as summer moong, mash pulses and guar act as green manure.
- They can be sown after wheat cultivation
Characteristics of green manure
- Green manure must be leguminous in nature
- They must bear maximum nodules on its roots to fix large amount of atmospheric nitrogen in the soil.
Various policy initiatives
- Under Sub- Mission on Seed and Planting Material (SMSP), the govt. provides 50% cost assistance for the distribution of green manure required for a one-acre area per farmer.
- The Paramparagat Krishi Vikas Yojana (PKVY) promotes cluster-based organic farming with PGS (Participatory Guarantee System) certification.

From UPSC perspective, the following things are important :
Prelims level: Highlights of State of the World’s Birds Report
Mains level: Not Much
The State of the World’s Birds, an annual review of environmental resources has revealed that the population of 48% of the 10,994 surviving species of birds is declining.
State of the World’s Birds
- The report is published by the Manchester Metropolitan University.
- It gives an overview of the changes in the knowledge of avian biodiversity and the extent to which it is imperilled.
- The study draws from BirdLife International’s latest assessment of all birds for the International Union for Conservation of Nature’s Red List.
What are the key findings of the study?
- The study found that 5,245 or about 48% of the existing bird species worldwide are known or suspected to be undergoing population declines.
- While 4,295 or 39% of the species have stable trends, about 7% or 778 species have increasing population trends.
- It shows 1,481 or 13.5% species are currently threatened with global extinction.
Where the birds are threatened the most?
- The more threatened bird species (86.4%) are found in tropical than in temperate latitudes (31.7%).
- Such hotspots are concentrated in the tropical Andes, southeast Brazil, eastern Himalayas, eastern Madagascar, and Southeast Asian islands.
What is the importance of birds to ecosystems and culture?
- Birds contribute toward many ecosystem services that either directly or indirectly benefit humanity.
- These include provisioning, regulating, cultural, and supporting services.
- The functional role of birds within ecosystems as pollinators, seed-dispersers, ecosystem engineers, scavengers and predators.
- They not only facilitate accrual and maintenance of biodiversity but also support human endeavours such as sustainable agriculture via pest control besides aiding other animals to multiply.
- For instance, coral reef fish productivity has been shown to increase as seabird colonies recovered following rat eradication in the Chagos archipelago.
- Wild birds and products derived from them are also economically important as food (meat, eggs).
What are the threats contributing to avian biodiversity loss?
- The study lists eight factors, topped by land cover and land-use change.
- The continued growth of human populations and of per capita rates of consumption lead directly to conversion and degradation of primary natural habitats.
- Deforestation has been driven by afforestation with plantations (often of non-native species) plus land abandonment in parts of the global North, with net loss in the tropics.
- The other factors are habitat fragmentation, degradation, hunting and trapping.

From UPSC perspective, the following things are important :
Prelims level: Martand Sun Temple
Mains level: Not Much
After Prayers held at the ruins of the eighth-century Martand Sun Temple in Jammu and Kashmir’s Anantnag is deemed to be a violation of the Archaeological Survey of India (ASI) rules.
About Martand Sun Temple
- The Martand Sun Temple is a Hindu temple located near the city of Anantnag in the Kashmir Valley.
- It dates back to the eighth century AD and was dedicated to Surya, the chief solar deity.
- The temple was destroyed by Sikandar Shah Miri in a bid to undertake mass conversion and execution of Hindus in the valley.
- According to Kalhana, the Temple was commissioned by Lalitaditya Muktapida in the eighth century AD.
- The temple is built on top of a plateau from where one can view whole of the Kashmir Valley.
- From the ruins the visible architecture seems to be blended with the Gandharan, Gupta and Chinese forms of architecture.
Why in news now?
- According to ASI, prayers are allowed at its protected sites only if they were “functioning places of worship” at the time it took charge of them.
- No religious rituals can be conducted at non-living monuments where there has been no continuity of worship when it became an ASI-protected site.
What are the living/non-living monument?
- If some activity, like any kind of worship, has been going on for years in the structure, then it is taken over as a living monument.
- But where no activity has taken place, say an abandoned building, then it is declared a dead monument.
- The latter is difficult to restore because it is generally covered by a lot of overgrowths.
- The best-known example of a living ASI monument is the Taj Mahal in Agra, where namaz is held every Friday.

From UPSC perspective, the following things are important :
Prelims level: Tropical cyclones
Mains level: Frequent recurrence of Cyclones in India
Severe cyclonic storm ‘Asani’, packing winds above 105 kmph and setting off heavy rain, is likely to make landfall on the eastern coast of India.
What are tropical Cyclones?
- A tropical cyclone is an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain.
- Cyclones are formed over slightly warm ocean waters. The temperature of the top layer of the sea, up to a depth of about 60 meters, need to be at least 28°C to support the formation of a cyclone.
- This explains why the April-May and October-December periods are conducive for cyclones.
- Then, the low level of air above the waters needs to have an ‘anticlockwise’ rotation (in the northern hemisphere; clockwise in the southern hemisphere).
- During these periods, there is an ITCZ in the Bay of Bengal whose southern boundary experiences winds from west to east, while the northern boundary has winds flowing east to west.
- Once formed, cyclones in this area usually move northwest. As it travels over the sea, the cyclone gathers more moist air from the warm sea which adds to its heft.
Requirements for a Cyclone to form
There are six main requirements for tropical cyclogenesis:
- Sufficiently warm sea surface temperatures
- Atmospheric instability
- High humidity in the lower to middle levels of the troposphere
- Enough Coriolis force to develop a low-pressure centre
- A pre-existing low-level focus or disturbance
- Low vertical wind shear
How are the cyclones named?
- In 2000, a group of nations called WMO/ESCAP (World Meteorological Organisation/United Nations Economic and Social Commission for Asia and the Pacific) decided to name cyclones.
- It comprised Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, decided to start naming cyclones in the region.
- After each country sent in suggestions, the WMO/ESCAP Panel on Tropical Cyclones (PTC) finalised the list.
- The WMO/ESCAP expanded to include five more countries in 2018 — Iran, Qatar, Saudi Arabia, United Arab Emirates and Yemen.
Why is it important to name cyclones?
- Adopting names for cyclones makes it easier for people to remember, as opposed to numbers and technical terms.
- It’s easier and less confusing to say “Cyclone Titli” than remember the storm’s number or its longitude and latitude.
- Apart from the general public, it also helps the scientific community, the media, disaster managers etc.
- With a name, it is also easy to identify individual cyclones, create awareness of its development, rapidly disseminate warnings to increase community preparedness etc.

From UPSC perspective, the following things are important :
Prelims level: Monkey Pox
Mains level: Zoonotic Diseases
The UK health authorities have confirmed a case of Monkeypox, which is a virus passed from infected animals such as rodents to humans, in someone with a recent travel history to Nigeria where they are believed to have caught it.
What is Monkeypox?
- The monkeypox virus is an orthopoxvirus, which is a genus of viruses that also includes the variola virus, which causes smallpox, and vaccinia virus, which was used in the smallpox vaccine.
- It causes symptoms similar to smallpox, although they are less severe.
- While vaccination eradicated smallpox worldwide in 1980, monkeypox continues to occur in a swathe of countries in Central and West Africa, and has on occasion showed up elsewhere.
- According to the WHO, two distinct clade are identified: the West African clade and the Congo Basin clade, also known as the Central African clade.
Its origin
- Monkeypox is a zoonosis, that is, a disease that is transmitted from infected animals to humans.
- Monkeypox virus infection has been detected in squirrels, Gambian poached rats, dormice, and some species of monkeys.
- According to the WHO, cases occur close to tropical rainforests inhabited by animals that carry the virus.
Symptoms and treatment
- Monkeypox begins with a fever, headache, muscle aches, back ache, and exhaustion.
- It also causes the lymph nodes to swell (lymphadenopathy), which smallpox does not.
- The WHO underlines that it is important to not confuse monkeypox with chickenpox, measles, bacterial skin infections, scabies, syphilis and medication-associated allergies.
- The incubation period (time from infection to symptoms) for monkeypox is usually 7-14 days but can range from 5-21 days.
- There is no safe, proven treatment for monkeypox yet.

From UPSC perspective, the following things are important :
Prelims level: El-Nino, La-Nina
Mains level: ENSO impact on Indian Monsson
This year the La Nina is being blamed for worsening the longest spell of heatwaves from March to April in north, west and Central India.
In most years, meteorologists considered the La Nina to be a friend of India.
What is El Nino and La Nina?
- While El Niño (Spanish for ‘little boy’), the more common expression, is the abnormal surface warming observed along the eastern and central regions of the Pacific Ocean (the region between Peru and Papua New Guinea).
- The La Niña (Spanish for ‘little girl’) is an abnormal cooling of these surface waters.
- Together, the El Niño (Warm Phase) and La Niña (Cool Phase) phenomena are termed as El Niño Southern Oscillation (ENSO).
- These are large-scale ocean phenomena which influence the global weather — winds, temperature and rainfall. They have the ability to trigger extreme weather events like droughts, floods, hot and cold conditions, globally.
- Each cycle can last anywhere between 9 to 12 months, at times extendable to 18 months — and re-occur after every three to five years.
- Meteorologists record the sea surface temperatures for four different regions, known as Niño regions, along this equatorial belt.
- Depending on the temperatures, they forecast either as an El Niño, an ENSO neutral phase, or a La Niña.
Impact on India
- El Nino during winter causes warm conditions over the Indian subcontinent and during summer, it leads to dry conditions and deficient monsoon.
- Whereas La Nina results in better than normal monsoon in India.
- It has been established that Indian summer monsoon is a fully coupled land-atmosphere-ocean system and that it is linked to ocean temperature variability.
- In an agricultural country like India, the extreme departure from normal seasonal rainfall seriously affects the agricultural output and thus the economy of the country.
Try this PYQ:
La Nina is suspected to have caused recent floods in Australia. How is La Nina different from El Nino?
- La Nina is characterized by unusually cold ocean temperature in equatorial Indian Ocean whereas El Nino is characterized by unusually warm ocean temperature in the equatorial Pacific Ocean.
- El Nino has an adverse effect on south-west monsoon of India, but La Nina has no effect on monsoon climate.
