    Explained: Repo Rate in India

    Note4Students

    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.

    RNA granules to treat neurodegenerative disorders

    Note4Students

    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.

  • Historical and Archaeological Findings in News

    Iron in Tamil Nadu 4,200 years ago: A new dating and its significance

    Note4Students

    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.

    From UPSC perspective, the following things are important:

    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.

    India Hypertension Control Initiative (IHCI)

    Note4Students

    From UPSC perspective, the following things are important:

    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.

  • Aadhaar Card Issues

    PAN, Aadhaar made mandatory for high-value cash deposits & withdrawals

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Cap on cash withdrawal

    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.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Green Manure

    Mains level: Soil Health Management

    The Punjab agriculture department is promoting the cultivation of green manure these days.

    What is the news?

    • Punjab Agro is providing subsidy on the seed at the rate of Rs 2,000 per quintal, which costs Rs 6,300 per quintal without subsidy
    • The farmers can avail its seed from the block level offices of the agriculture department as limited stock is available.

    What is Green Manure?

    • 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
    1. Dhaincha
    2. Cowpea
    3. 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.

    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.
