From UPSC perspective, the following things are important :
Prelims level: Arsenic Poisoning
Mains level: Not Much
Central Idea: A recent peer-reviewed study suggests that even low levels of arsenic consumption can affect cognitive function in children, adolescents, and young adults.
Arsenic Contamination
- Arsenic is a highly toxic element naturally present in the environment.
- Contaminated water, particularly groundwater, is a major source of arsenic exposure.
- Long-term arsenic exposure can lead to various health issues, including cancer, skin lesions, cardiovascular disease, and negative impacts on cognitive development.
Menace in India
- Arsenic contamination in groundwater is one of the most crippling issues in the drinking water scenario of India.
- According to the latest report of the Central Ground Water Board (CGWB), 21 states across the country have pockets with arsenic levels higher than the BIS stipulated permissible limit of 0.01 milligram per litre (mg/l).
- The states along the Ganga-Brahmaputra-Meghna (GBM) river basin — Uttar Pradesh, Bihar, Jharkhand, West Bengal and Assam — are the worst affected by this human-amplified geogenic occurrence.
- In India, arsenic contamination was first officially confirmed in West Bengal in 1983.
- Close to four decades after its detection, the scenario has worsened.
- About 9.6 million people in West Bengal, 1.6 million in Assam, 1.2 million in Bihar, 0.5 million in Uttar Pradesh and 0.013 million in Jharkhand are at immediate risk from arsenic contamination in groundwater.
Key findings of the recent study
(1) Arsenic impact on behaviour
- The study found that individuals exposed to arsenic had reduced grey matter and weaker connections within key regions of the brain associated with cognitive functions.
- Chronic exposure to arsenic could have significant consequences at a population level, leading to increased school failures, diminished economic productivity, and higher risks of criminal and antisocial behavior.
(2) Arsenic Exposure and Socioeconomic Factors
- As previous studies have shown, arsenic exposure is particularly harmful to the poor.
- The recent study reaffirms that economically and nutritionally disadvantaged individuals experience greater cognitive impairment from arsenic exposure.
- The impact of arsenic on impairing cognition is more pronounced at a collective level rather than at an individual level.
Government Initiatives to address Arsenic Contamination
- Governments in Bihar and West Bengal have taken steps to address arsenic contamination since the 1990s.
- Strategies include promoting piped water access, installing arsenic removal plants, and encouraging groundwater extraction from deeper aquifers with lower arsenic levels.
- The goal is to minimize arsenic exposure and mitigate its health impacts in affected regions.
Possible solutions
Some of the management options include
- Uses of surface water sources
- Exploring and harnessing alternate arsenic-free aquifer
- Removal of arsenic from groundwater using arsenic treatment plants/filters
- Adopting rainwater harvesting/ watershed management practices.

Prelims level: Liberalised Remittance Scheme (LRS)
Mains level: Not Much
Central Idea: The Centre has amended rules under Foreign Exchange Management Act (FEMA) Rules, bringing international credit card spends under the Liberalised Remittance Scheme (LRS).
Changes introduced
- Credit card spends outside India now fall under the LRS, allowing for the application of a higher TCS rate.
- The amendment removes the exclusion of credit card transactions from the LRS, which was previously covered under Rule 7 of the Foreign Exchange Management (Current Account Transaction) Rules, 2000.
- The changes do not apply to payments for the purchase of foreign goods/services from India.
What is Liberalised Remittance Scheme (LRS)?
- LRS is a facility provided by the Reserve Bank of India (RBI) to resident individuals to remit funds abroad for permitted current or capital account transactions or a combination of both.
- The scheme was introduced in 2004 and has been periodically reviewed and revised by the RBI.
- Under the scheme, resident individuals can remit up to a certain amount in a financial year for permissible transactions including education, travel, medical treatment, gifts, and investments in equity and debt securities, among others.
- The limit for LRS is currently set at USD 250,000 per financial year.
Eligibility for LRS
- LRS is open to everyone including non-residents, NRIs, persons of Indian origin (PIOs), foreign citizens with PIO status and foreign nationals of Indian origin.
- The Scheme is NOT available to corporations, partnership firms, Hindu Undivided Family (HUF), Trusts etc.
Benefits provided by LRS
- LRS is an easy process that anyone can use to transfer money between two countries.
- It’s especially useful for businesses because they can use it to transfer funds to India, and investors can receive their investments back home.
- LRS also has some added benefits, like fast transfer timing and no issues with exchange rates.
Concerns with credit card spends
- The amendment aims to achieve parity between the usage of credit and debit cards, which were already covered under the LRS.
- Instances of disproportionately high LRS payments compared to disclose incomes prompted the amendment.
- Business visits of employees, where costs are borne by the employer, are not covered under the LRS.
- The data collected from major money remitters under the LRS indicated that international credit cards were being issued with limits exceeding the prescribed norm.
Exclusions and impact of the Scheme
- The government assured that the LRS scheme would not cover genuine business visits abroad by employees.
- The imposition of a 20% tax collection on source (TCS) for foreign remittances would primarily affect tour travel packages, gifts to non-residents, and domestic high net-worth individuals investing in assets like real estate, bonds, and stocks outside India.
- The Ministry emphasized that the 5% TCS levied on medical or education expenses abroad, allowed up to ₹7 lakh per year, and would remain unchanged.

From UPSC perspective, the following things are important :
Prelims level: Green Deposits
Mains level: Not Much
Central Idea: The Reserve Bank of India (RBI) has introduced a regulatory framework to govern the acceptance of green deposits by banks, ensuring transparency and accountability in their investments.
What are Green Deposits?
- Green deposits are financial products offered by banks that are similar to regular deposits, but the money received is specifically earmarked for environmentally friendly projects.
- These deposits support projects aimed at combating climate change, such as renewable energy initiatives, while avoiding investments in activities that harm the environment, like fossil fuel projects.
- They are part of a broader range of financial products, including green bonds and green shares that enable investors to contribute to environmentally sustainable projects.
Regulatory framework for accepting Green Deposits
- The RBI’s framework mandates that banks establish a set of rules or policies, approved by their respective Boards, to guide the investment of green deposits.
- These rules must be made public on the banks’ websites, ensuring transparency and enabling customers to make informed decisions.
- Banks are required to disclose information on the amount of green deposits received, how these funds are allocated to different green projects, and the environmental impact of such investments.
- To verify the banks’ claims and the sustainability credentials of the projects, a third-party is appointed to conduct independent verification.
Sectors eligible for green deposits
- The RBI has identified a list of sectors classified as sustainable, which are eligible to receive green deposits.
- These sectors include renewable energy, waste management, clean transportation, energy efficiency, and afforestation.
- Banks are prohibited from investing green deposits in sectors considered detrimental to the environment, such as fossil fuels, nuclear power, tobacco, gambling, palm oil, and hydropower generation.
Addressing greenwashing
- Greenwashing refers to the practice of making misleading claims about the positive environmental impact of an activity or investment.
- The RBI’s regulatory framework aims to prevent greenwashing in the banking sector by ensuring that the actual impact of green deposits is accurately represented.
- By requiring transparency, disclosure, and third-party verification, the framework aims to protect customers from deceptive practices and ensure genuine environmental benefits.
Impact and controversies
- Depositors who prioritize environmental concerns may find satisfaction in investing their money in environmentally sustainable products like green deposits.
- However, some critics argue that green investment products may primarily serve to make investors feel good without generating significant environmental benefits.
- Additionally, the range of projects available for investment through green deposits may be limited, posing challenges in achieving broad environmental impact.
Key challenge: Assessing environmental sustainability
- Evaluating the true environmental sustainability of a project can be challenging in a complex world with interconnected systems and second-order effects that are difficult to anticipate.
- It is essential to consider the indirect consequences and long-term effects of actions to determine if a project genuinely contributes to environmental sustainability.
- Uncertainty surrounding the actual environmental impact of green projects highlights the need for rigorous evaluation and ongoing monitoring to ensure the desired outcomes are achieved.

From UPSC perspective, the following things are important :
Prelims level: ASTR, AI
Mains level: Not Much
Central Idea: The Department of Telecommunications (DoT) has developed an artificial-intelligence-based facial recognition tool called Artificial Intelligence and Facial Recognition powered Solution for Telecom SIM Subscriber Verification (ASTR).
What is ASTR?
- ASTR is designed to check subscriber databases of telecom operators to identify multiple connections associated with the same person.
- The goal of ASTR is to detect and block fraudulent mobile connections, thereby reducing cyber frauds.
Development of ASTR
- In 2012, DoT issued an order requiring telecom operators to share their subscriber database, including users’ pictures, with the department.
- These images serve as the core database for facial recognition using ASTR.
- The ASTR project was conceptualized and designed by the DoT’s unit in Haryana between April 2021 and July 2021.
- A pilot project was conducted in Haryana’s Mewat region to test the feasibility of ASTR, where a significant number of fraudulent SIMs were detected.
How ASTR works?
- ASTR uses convolutional neural network (CNN) models to encode human faces in subscribers’ images, accounting for various factors like face tilt, angle, image opaqueness, and dark color.
- A face comparison is performed for each face against all faces in the database, grouping similar faces under one directory.
- ASTR considers two faces to be identical if they match to a minimum extent of 97.5%.
- It can detect all SIMs associated with a suspected face within 10 seconds from a database of 1 crore (10 million) images.
- After matching faces, ASTR’s algorithm utilizes “fuzzy logic” to find approximate matches for subscriber names, considering variations, typographical errors, and related results.
Impact and Results
- In the first phase, ASTR analyzed over 87 crore (870 million) mobile connections and detected more than 40 lakh (4 million) cases of people using a single photograph to obtain multiple connections.
- After verification, over 36 lakh (3.6 million) connections were discontinued by telecom operators.
- The list of fraudulent connections is also shared with banks, payment wallets, and social media platforms to disengage these numbers from their respective platforms.
- WhatsApp collaborated with the government to disable accounts created using such numbers, and similar efforts are being made with other social media platforms.
Facts for Prelims
Convolutional Neural Network (CNN): A type of deep learning algorithm commonly used for image recognition tasks, where it extracts features and patterns from images by applying convolution operations.
Fuzzy Logic: A form of logic that deals with approximate or qualitative reasoning rather than strict binary true/false values. In the context of ASTR, it is used to find similarity or approximate matches for subscriber names, accounting for variations and typographical errors. |

From UPSC perspective, the following things are important :
Prelims level: Vacuum gas oil (VGO)
Mains level: Reprocessing Russian oil
Central Idea
- The article discusses India’s increased imports of Russian oil and the potential circumvention of sanctions imposed on Russian oil products.
Why in news?
- An EU parliamentarian accused India of profiting from cheaply bought Russian oil and indirectly supporting the Russian economy.
- India justified its purchase by emphasizing its energy demands and the challenges of higher prices due to its reliance on energy imports and significant poverty levels.
Reasons: Sanctions against Russian Oil
- After Russia’s invasion of Ukraine, Western countries and Europe aimed to reduce their dependency on Russian energy imports to weaken the Russian economy.
- Measures were taken, such as Germany suspending the launch of the Nord Stream natural gas pipeline and Canada and the US banning the import of Russian crude oil.
- Stricter sanctions were imposed on Russia, including a “price cap” from trading Russian oil above $60 per barrel.
- The price cap aimed to cripple Moscow’s economy and limit its ability to fund the war in Ukraine.
- However, Russia increased its oil exports to India and China as a response.
India’s role in meeting West’s energy demand
- India, exempt from the sanctions on Russian oil, has seen a significant increase in fuel imports from Russia, which is then refined and supplied to Europe and the US.
- The refined oil from Russian crude, once processed in India, is not considered of Russian origin.
- India’s oil imports have helped it meet its own energy demands and also assist Western nations facing energy crises due to the Russia-Ukraine conflict.
- India has become a net exporter of refined petroleum products, supplying the West to alleviate current energy shortages.
Impact of Indian imports on Western markets
- Indian refiners have ramped up exports of refined petroleum products, including diesel and vacuum gas oil (VGO), to Europe and the US.
- VGO is a feedstock in the refining process that can be further processed to produce gasoline, diesel, and other fuel products.
- Diesel exports to Europe from India have increased by 12-16% in the last fiscal year.
- The US has become a major recipient of Indian VGO shipments, receiving 11,000-12,000 barrels per day (bpd) or 65-81% of India’s VGO exports.
- These exports from India have helped ease the energy tightness and supply constraints in Western markets.

From UPSC perspective, the following things are important :
Prelims level: Monsoon terminologies
Mains level: Not Much
Central Idea: The monsoon is likely to set in over Kerala with a “slight delay” on June 4, the India Meteorological Department (IMD) said. The usual onset date over Kerala is June 1, within a seven-day window.
What does the “Onset of Monsoon” mean?
- The onset of the monsoon over Kerala marks the beginning of the four-month, June to September southwest monsoon season over India.
- It brings more than 70 per cent of the country’s annual rainfall.
- It marks a significant transition in the large-scale atmospheric and ocean circulations in the Indo-Pacific region.
- The IMD announces it only after certain newly defined and measurable parameters, adopted in 2016, are met.
- The onset is a significant day in India’s economic calendar.
How does IMD predict the monsoon?
- Broadly, the IMD checks for the consistency of rainfall over a defined geography, its intensity, and wind speed:
- Rainfall: The IMD declares the onset of the monsoon if at least 60% of 14 designated meteorological stations in Kerala and Lakshadweep record at least 2.5 mm of rain for two consecutive days at any time after May 10.
- Wind field: The depth of westerlies should be upto 600 hectopascal (1 hPa is equal to 1 millibar of pressure) in the area bound by the equator to 10ºN latitude, and from longitude 55ºE to 80ºE. The zonal wind speed over the area bound by 5-10ºN latitude and 70-80ºE longitude should be of the order of 15-20 knots (28-37 kph) at 925 hPa.
- Heat: The INSAT-derived Outgoing Longwave Radiation (OLR) value (a measure of the energy emitted to space by the Earth’s surface, oceans, and atmosphere) should be below 200 watt per sq m (wm2) in the box confined by 5-10ºN latitude and 70-75ºE latitude.
- The onset is not officially declared until the prescribed conditions (above) are met.
Factors considered by IMD
- The IMD uses a specialised model that forecasts the arrival dates within a four-day window.
- It uses six predictors:
- Minimum temperatures over northwest India
- Pre-monsoon rainfall peak over south Peninsula
- Outgoing long-wave radiation (OLR) over the South China Sea
- Lower tropospheric zonal wind over the southeast Indian Ocean
- Upper tropospheric zonal wind over the east equatorial Indian Ocean, and
- OLR over the southwest Pacific region
Back2Basics: Long Period Average (LPA)
- The IMD predicts a “normal”, “below normal”, or “above normal” monsoon in relation to a benchmark “long period average” (LPA).
- The LPA of rainfall is the rainfall recorded over a particular region for a given interval (like month or season) average over a long period like 30 years, 50 years, etc.
- LPA refers to the average rainfall recorded from June to September for the entire country, the amount of rain that falls every year varies from region to region and from month to month.
- The IMD’s prediction of a normal monsoon is based on the LPA of the 1971-2020 period, during which India received 87 cm of rain for the entire country on average.
- It has in the past calculated the LPA at 88 cm for the 1961-2010 period, and at 89 cm for the period 1951-2000.
Why LPA is needed?
- The IMD records rainfall data at more than 2,400 locations and 3,500 rain-gauge stations.
- Because annual rainfall can vary greatly not just from region to region and from month to month, but also from year to year within a particular region or month.
- An LPA is needed to smooth out trends so that a reasonably accurate prediction can be made.
- A 50-year LPA covers for large variations in either direction caused by freak years of unusually high or low rainfall, as well as for the periodic drought years.
- It also takes into account the increasingly common extreme weather events caused by climate change.
Range of normal rainfall
The IMD maintains five rainfall distribution categories on an all-India scale. These are:
- Normal or near normal, when the percentage departure of actual rainfall is +/-10% of LPA, that is, between 96-104% of LPA;
- Below normal, when departure of actual rainfall is less than 10% of LPA, that is 90-96% of LPA;
- Above normal, when actual rainfall is 104-110% of LPA;
- Deficient, when departure of actual rainfall is less than 90% of LPA; and
- Excess, when the departure of actual rainfall is more than 110% of LPA.

From UPSC perspective, the following things are important :
Prelims level: Merger of Sikkim
Mains level: Not Much
Sikkim Statehood Day
- Sikkim day is annually celebrated on May 16, commemorating the integration of Sikkim with India in 1975.
- The process of Sikkim joining India occurred about two decades after Sardar Vallabbhai Patel led the integration of princely states into India.
Sikkim’s History with the Chogyal Royals
- The kingdom of Sikkim was established in 1642 when Phuntsong Namgyal was consecrated as the first ruler or Chogyal.
- Sikkim’s monarchy, under the Namgyal dynasty, lasted for 333 years until its integration with India in 1975.
- Sikkim had a Tibetan origin and was located between India and China. It often faced conflicts over land with Bhutan and Nepal.
- The British saw Sikkim as a buffer state and established a formal relationship with it.
- Various treaties like the Treaty of Tumlong (1861), Treaty of Titaliya (1817), Calcutta Convention (1890), and Lhasa Convention (1904) shaped the relationship between Sikkim and the British.
Independent India and Sikkim
- After India’s independence, princely states had the option to accede to India or Pakistan.
- Sikkim’s unique relationship with British rule led to complexities in its integration with India.
- Sardar Vallabbhai Patel and BN Rau wanted Sikkim to sign the Instrument of Accession to integrate it with India.
- Jawaharlal Nehru acknowledged the situation in Sikkim and emphasized its autonomous growth.
- Sikkim State Congress (SSC), Praja Mandal (PM), and Praja Sudharak Samaj (PSS) demanded a popular government, abolition of landlordism, and accession to India.
- A Standstill Agreement was signed to maintain the existing arrangement while discussions continued.
War with China
- Sikkim had a state council with elected and nominated members.
- Political developments in the 1960s and 1970s played a significant role in Sikkim’s status.
- The formation of the Sikkim National Congress (SNC) in 1960 and changes in political leadership on both sides influenced the course of events.
- India-China war of 1962 and containment of border skirmishes made it important to clarify the relationship between India and Sikkim.
How Sikkim finally joined India?
- The Indian leadership started supporting pro-democracy forces in Sikkim, such as Kazi Dorji of the SNC.
- Protests in Sikkim in 1973 led to a tripartite agreement between the Chogyal, the Indian government, and three major political parties.

From UPSC perspective, the following things are important :
Prelims level: Mitochondrial Replacement Therapy (MRT)
Mains level: Various ARTs
Central Idea
- The birth of a baby using three persons’ DNA using Mitochondrial Replacement Therapy (MRT) in the UK has generated significant attention and discussion.
- The baby has three parents, with the mitochondria coming from a donor in addition to the genetic material from the biological parents.
- This pioneering technology was employed to prevent the baby from inheriting the mother’s mitochondrial disease.
What is Mitochondria?
|
Description |
| Structure |
Membrane-bound organelles with outer and inner membranes |
| Energy Production |
Generate ATP through cellular respiration and oxidative phosphorylation |
| ATP Production |
Breakdown of carbohydrates, fats, and proteins in the inner membrane |
| DNA and Replication |
Possess their own circular DNA (mtDNA) and can replicate independently |
| Other Functions |
Involved in calcium signalling, apoptosis, and synthesis of molecules |
| Inheritance |
Maternally inherited during fertilization |
| Evolutionary Origin |
Arise from a symbiotic relationship with bacteria-like organisms |
| Disorders |
Mutations or dysfunction can cause mitochondrial diseases |
- Certain defects in mitochondria can lead to mitochondrial diseases, impacting the function of energy-hungry tissues in various organs.
- Mitochondrial diseases have no cure but can be treated, and their incidence is estimated to be one in 5,000 people.
- In this case, the mother had a mitochondrial disease that she wanted to avoid passing on to her baby, but she did not want to use a donor egg.
What is Mitochondrial Replacement Therapy (MRT)?
- MRT is a medical technique used to prevent the transmission of certain mitochondrial diseases from a mother to her child.
- It involves replacing faulty mitochondria in an egg or embryo with healthy mitochondria from a donor.
- The procedure is typically performed using in vitro fertilization (IVF) techniques.
- The nucleus, containing the majority of the genetic material, is transferred from the intended parents’ egg or embryo to a donor egg or embryo with healthy mitochondria.
- The resulting embryo, with nuclear DNA from the intended parents and healthy mitochondria from the donor, is then implanted into the mother’s uterus for gestation.
How does it work?
- The father’s sperm fertilizes the eggs from the biological mother and a female donor with healthy mitochondria.
- The genetic material from the donor’s egg is replaced with that of the biological parents, resulting in an egg with the parents’ DNA and the donor’s mitochondria.
- This modified egg is then implanted into the mother’s uterus and carried to full term, resulting in a baby free from the mother’s mitochondrial disease.
Uses of MRT
- Prevention of Mitochondrial Diseases: MRT helps prevent the transmission of certain mitochondrial diseases from mothers to their children.
- Family Planning: It enables individuals or couples with mitochondrial DNA mutations to have genetically related children without the risk of disease inheritance.
- Improved Health: MRT can significantly improve the overall health and well-being of individuals by avoiding debilitating mitochondrial diseases.
- Ethical Considerations: It provides an alternative to traditional donor egg options, allowing intended parents to have a child with their own genetic material while avoiding disease transmission.
- Scientific Advancements: MRT contributes to scientific research and advancements in assisted reproductive technologies, expanding our understanding of mitochondrial biology and potential treatment options for mitochondrial disorders.
Recent advancements in UK
- The baby primarily carries DNA from its biological parents and a small percentage from the donor whose mitochondria was used during fertilization.
Scientific process
- Mitochondrial diseases are inherited from the mother, prompting research to find ways to protect infants from inheriting these diseases.
- The Newcastle Fertility Clinic developed an advanced in vitro fertilization technique known as Mitochondrial Donation Treatment (MDT).
Legal Facilitation of MDT
- The UK government amended the law in 2015 to allow for mitochondrial replacement therapy (MRT) or MDT.
- The Newcastle Fertility Centre became the first center to obtain a license to perform the procedure, and the first cases were approved in 2018.
Issues with MRT
- Transfer of Defective Mitochondria: There is a minimal risk of transferring small amounts of defective mitochondria along with healthy ones during the procedure.
- Long-Term Safety: The long-term safety of MRT is still being studied, and ongoing monitoring is necessary to assess any potential risks or effects.
- Ethical and Social Concerns: MRT raises ethical and social considerations related to the creation and destruction of embryos, use of donor gametes, and altering the germline.
- Limited Availability: MRT is a highly regulated procedure, and its availability may be limited to specific countries or cases approved by regulatory bodies.
- Emotional and Psychological Impact: Undergoing MRT involves emotional implications and decision-making, which can have an impact on individuals and couples involved.

From UPSC perspective, the following things are important :
Prelims level: Palghat Gap, Western Ghats
Mains level: Not Much
Central Idea: The article discusses the Palghat (Palakkad) Gap, a significant corridor in the Western Ghats of India. It provides information about the geological origin of the gap.
What is Palghat Gap?
- The Palghat Gap is a 40 km wide corridor in the Western Ghats, known for its steep hills and serving as a gateway to Kerala.
- It is a crucial passage for roads and railways connecting Coimbatore and Palakkad.
- The Bharathappuzha River flows through the Palghat Gap.
- The vegetation in the gap is classified as dry evergreen forest, different from the tropical rainforests of the Western Ghats.
- The Palghat Gap marks a distinct divide in the flora and fauna of the region.
Geological origin of the Palghat Gap
- The Palghat Gap is a geological shear zone running from east to west.
- Shear zones are weak regions in the Earth’s crust, occasionally causing tremors in the Coimbatore region.
- The formation of the Palghat Gap occurred when the continental shelves shifted after the separation of Australia and Africa from the Gondwana landmass.
- India and Madagascar were connected until volcanic activity led to their split, with a similar gap called the Ranotsara Gap in Madagascar.
Biogeographic distinctions and ancient history
- The biogeographic distinctions in species north and south of the Palghat Gap may be attributed to an ancient river or an incursion of the sea in the distant past.
- Elephant populations on the Nilgiris side of the gap have different mitochondrial DNA from elephants in the Anamalai and Periyar sanctuaries.
- DNA analysis of the White-bellied Shortwing, an endemic bird species, shows divergence between populations in the Nilgiris and the Anamalai regions.
Biodiversity south of the Palghat Gap
- The southern region of the Western Ghats, located south of the Palghat Gap, exhibits high species richness and phylogenetic diversity.
- A recent study reports over 450 tree species, including ancient species like Magnolia champaca, dating back 130 million years.
- The warm weather and moist air of the southern Western Ghats support a diverse range of life, making it an island refuge during cycles of ice ages and droughts.
- The southern Western Ghats receive rainfall more evenly throughout the year compared to the northern region.
Back2Basics: Western Ghats
- The Western Ghats, also known as the Sahyadri mountain range, is a UNESCO World Heritage Site and one of the 36 biodiversity hotspots in the world.
- It spans an area of 160,000 sq. km. and stretches for 1,600 km parallel to the western coast of the Indian peninsula, passing through the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.
|
Description |
| Flora and Fauna |
The Western Ghats are home to a rich diversity of flora and fauna, including over 7,402 species of flowering plants, 1,814 species of non-flowering plants, 139 mammal species, 508 bird species, 227 reptile species, 179 amphibian species, 290 freshwater fish species, and 6,000 insect species. |
| Geological Significance |
The Western Ghats, known as the “Great Escarpment of India,” are older than the Himalayas. They influence India’s monsoon weather patterns by intercepting rain-laden monsoon winds from the southwest during late summer. |
| Geographic Features |
Stretching north to south along the western edge of the Deccan Plateau, the Western Ghats separate the plateau from the narrow coastal plain called the Western Coastal Plains, which lies along the Arabian Sea. |
| Catchment Area |
The Western Ghats cover a vast catchment area for complex riverine drainage systems, contributing to almost 40% of India’s total drainage. The range acts as a barrier, blocking southwest monsoon winds from reaching the Deccan Plateau. |

From UPSC perspective, the following things are important :
Prelims level: London Interbank Offered Rate (LIBOR)
Mains level: Read the attached story
Central Idea: The RBI has issued an advisory to banks and other RBI-regulated entities regarding the transition away from London Interbank Offered Rate (LIBOR) July 1.
What is London Interbank Offered Rate (LIBOR)?
|
Explanation |
| Definition |
LIBOR is a benchmark interest rate used in financial transactions such as loans, derivatives, and bonds.
It is the interest rate at which banks can borrow funds from other banks in the London interbank market.
It serves as a benchmark rate for various financial transactions worldwide. |
| Calculation Method |
LIBOR rates are calculated based on submissions from a panel of major banks in London.
These banks estimate their borrowing costs for various currencies and tenors.
The submissions are used to calculate an average rate, which is published daily by the Intercontinental Exchange (ICE), the administrator of LIBOR. |
| Currencies and Tenors |
LIBOR is calculated for different currencies and tenors ranging from overnight to one year.
The currencies include USD, EUR, GBP, JPY, CHF, and others.
The tenors represent the time periods for which the rates are quoted. |
| Importance |
It has been widely used since the 1980s as a benchmark for financial contracts worth trillions of dollars globally.
It serves as a reference rate for various loans, derivatives, and other financial instruments. |
Why is RBI moving away from LIBOR?
Like many other countries, has been working towards transitioning away from LIBOR. The primary reasons for this transition include:
- Manipulation risks: Following the global financial crisis in 2008, there were concerns about the reliability and potential manipulation of LIBOR.
- Discontinuation of LIBOR: The regulatory authority in the UK that oversees LIBOR, announced in 2017 that it will no longer compel banks to submit the necessary data to calculate LIBOR after the end of 2021.
- Adoption of alternative Reference Rates: Various countries, including India, have identified and adopted alternative reference rates that are more reliable and based on actual market transactions. Ex RBI introduced the Secured Overnight Financing Rate (SOFR).
- Alignment with International Standards: Many countries have already initiated the shift to alternative reference rates, necessitating India’s alignment to maintain consistency and harmonization in international financial markets.
- Risk Mitigation: RBI’s move aims to mitigate the potential risks associated with an unreliable or manipulated benchmark rate.
Related terminologies
Mumbai Interbank Forward Outright Rate (MIFOR): MIFOR is a benchmark rate used in Indian financial markets. It represents the forward premium or discount on the USD-INR exchange rate based on the LIBOR rate.
Fallbacks: They are provisions inserted into contracts to establish alternative reference rates if the original benchmark rate (such as LIBOR) becomes unavailable or unreliable. |

From UPSC perspective, the following things are important :
Prelims level: Carbon Dating
Mains level: Not Much
Central Idea: Allahabad high court ordered the ASI to conduct the carbon dating process of the ‘Shivling’ found in the premises of the Gyanvapi mosque, without causing any damage to the structure.
What is Carbon Dating?
- Carbon dating is a widely-used method for determining the age of organic materials that were once living.
- The method is based on the radioactive decay of Carbon-14 (C-14), an isotope of carbon with an atomic mass of 14.
- It works by measuring the ratio of C-12 to C-14 in the atmosphere, as well as in plants and animals that acquire carbon through photosynthesis or food consumption.
The half-life concept
- Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.
- Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.
Limitations of Carbon Dating
- Carbon dating has certain limitations and cannot be applied in all circumstances.
- It is not suitable for determining the age of non-living things such as rocks.
- Carbon dating becomes less accurate for objects older than 40,000-50,000 years, as the amount of detectable C-14 becomes significantly small.
- Other radiometric dating methods are employed to determine the age of inanimate objects, which rely on the decay of radioactive elements present in the material.
- Examples of such methods include potassium-argon dating and uranium-thorium-lead dating, which analyze the ratios of specific isotopes to estimate the age of rocks.
Other Dating Methods
In addition to radiometric dating, there are alternative methods to determine the age of objects.
- Cosmogenic nuclide dating: CRN is one such method that utilizes radioactive decay to estimate age and is commonly used to study the age of ice cores in Polar Regions.
- Potassium-argon dating: A radiometric dating method that measures the ratio of potassium to argon isotopes in rocks to determine their age.
- Uranium-thorium-lead dating: A radiometric dating method that analyses the ratios of uranium, thorium, and lead isotopes in rocks to estimate their age.
