Radiocarbon dating

Archaeologists have used radiocarbon dating to analyze the oldest true wooden frame saddle in East Asia, revealing how the rise of Mongolian steppe cultures was likely aided by advances in equestrian technology.

• Radiocarbon dating, also known as carbon-14 dating, is a widely used method for determining the age of organic materials based on the decay rate of the radioactive isotope carbon-14 (^14C).
• This technique has revolutionized archaeology, anthropology, and other fields that study the past.

What is Carbon-14?

• Carbon is an essential element found in all living organisms.
• Most carbon atoms are stable, but a small fraction are radioactive isotopes like carbon-14.
• Cosmic rays constantly bombard the Earth''s atmosphere, producing ^14C.
• When living organisms consume carbon through photosynthesis or eating, they incorporate a small amount of carbon-14 into their tissues.

Radioactive Decay of Carbon-14:

• Carbon-14 is radioactive and undergoes a process called radioactive decay.
• It decays into nitrogen-14 (^14N) through beta decay, emitting a beta particle (electron) and an antineutrino in the process.
• The half-life of carbon-14 is approximately 5,730 years.
• This means that after this period, half of the initial amount of carbon-14 in a sample will have decayed to nitrogen-14.

Dating Process

• Sample Collection: Archaeologists or scientists extract samples containing organic material, such as wood, bone, charcoal, or organic sediments, from the site of interest.
• Isolation of Carbon: The extracted material undergoes processing to isolate carbon in the form of graphite or carbon dioxide gas.
• Measuring Carbon-14 Content: Accelerator Mass Spectrometry (AMS) or other sensitive techniques are used to measure the ratio of carbon-14 to stable carbon-12 (^12C) in the sample.
• Calibration: The obtained ratio is compared to the known standard ratio to correct for fluctuations in atmospheric carbon-14 levels throughout history. This calibration accounts for changes caused by factors like solar activity and volcanic eruptions.
• Calculating Age: Using the measured ratio of ^14C to ^12C and its known half-life, scientists calculate the age of the sample. The equation used is based on the exponential decay of carbon-14.

Limitations and Considerations

• Half-Life Limitation: Radiocarbon dating is effective up to around 50,000 years, as after this time, the amount of remaining carbon-14 becomes too low to accurately measure.
• Contamination: Contamination by newer or older carbon-containing substances can skew results. Careful sample preparation and analysis are crucial to avoid this.
• Calibration Issues: Calibration curves are used to account for fluctuations in atmospheric ^14C levels, but uncertainties can still exist, affecting the accuracy of the dating.

Applications

• Archaeology: Dating ancient artifacts, human remains, and historical sites.
• Geology: Studying the age of organic materials in geological contexts.
• Climate Science: Analyzing carbon cycles and changes in the Earth''s atmosphere.

Radiocarbon dating provides invaluable insights into the age of organic materials and has significantly contributed to our understanding of human history and the natural world. Despite its limitations, it remains a powerful tool in scientific research. Continuous advancements in technology and calibration methods enhance its accuracy and broaden its applications across various disciplines.

Red sprite

A European Space Agency (ESA) astronaut recently photographed an uncommon occurrence termed a red sprite.

• Red sprites are fascinating and elusive atmospheric phenomena associated with thunderstorms.
• These transient events occur high above the Earth''s surface in the mesosphere and are often witnessed during powerful thunderstorms.

What are Red Sprites?

• Appearance: Red sprites are bright, large-scale electrical discharges that appear above thunderstorms as luminous reddish-orange flashes or tendrils. They extend upwards from the tops of thunderclouds, reaching heights between 50 to 90 kilometers (30 to 55 miles) above the Earth''s surface.
• Formation: They are part of the family of transient luminous events (TLEs) that occur due to the interaction of lightning-generated electric fields and the Earth''s upper atmosphere. Red sprites occur in response to intense lightning discharges within thunderstorms.
• Structure: Sprites often exhibit complex shapes, including pillars, carrots, or jellyfish-like configurations. They are extremely brief, lasting only milliseconds.

How Do Red Sprites Form?

• Storm Conditions: Red sprites typically occur in conjunction with powerful thunderstorms known as mesoscale convective systems (MCSs), which produce strong electrical activity in the form of cloud-to-ground lightning strikes.
• Electrical Processes: Lightning discharges in thunderstorms create intense electric fields. These electric fields extend upward into the mesosphere, interacting with the ionosphere and generating the conditions necessary for red sprite formation.
• Ionization and Emission: The electric fields cause the ionization of gases in the upper atmosphere, leading to the emission of light, which manifests as red sprites. The precise mechanisms behind the formation of red sprites are still being studied.

Characteristics and Observations

• Color and Appearance: Red sprites are named for their reddish color, though they can also appear orange or pink. They are often dimly visible to the naked eye and can be captured by high-speed cameras sensitive to low-light conditions.
• Scale: These phenomena can be immense, spanning several tens of kilometers horizontally and reaching heights greater than typical lightning.
• Rarity: Red sprites are relatively rare and challenging to observe due to their fleeting nature, occurring in less than 1% of thunderstorms worldwide.

Research and Significance

• Scientific Interest: Understanding red sprites provides insights into the Earth''s upper atmosphere, ionosphere, and the behavior of electrical discharges in different atmospheric layers.
• Technological Advances: High-speed cameras and sensitive instruments aboard aircraft and satellites have enabled researchers to capture and study red sprites, enhancing our knowledge of these elusive phenomena.

Red sprites are captivating atmospheric events occurring high above thunderstorms, representing a complex interplay between thunderstorm activity and the Earth''s upper atmosphere. Ongoing research continues to unravel the mysteries surrounding their formation and significance in atmospheric science. Despite their rarity, advancements in technology and observational techniques have improved our understanding of these ethereal phenomena.

India’s extreme Rainfall Corridor

• How has the Indian monsoon been affected by global warming? What has a new study on large-scale extreme rainfall found and what is its significance? How will this study improve forecasts and reduce risks associated with large-scale rainfall events?
• The Indian monsoon has well-known features, such as the onset of the monsoon, the withdrawal, the active and break periods, and the low-pressure systems (or monsoon depressions).
• Every aspect of the monsoon has been affected by global warming.
• The total seasonal rainfall has also trended downwards for more than seven decades, due to the differential heating of the land versus the ocean due to global warming.
• However, this trend has been distributed unevenly through the monsoon season — as manifested in the longer duration but lower intensity of dry spells and the greater intensity of wet spells.
• While the India Meteorological Department (IMD) has made progress in forecasting extremes, multiple factors can combine to produce devastating heavy rain events that remain hard to anticipate.

Where does extreme rain occur?

• India’s monsoon forecasts rely heavily on its relation to the El Niño and the La Niña phenomena, although this relation holds only about 60% of the time.
• We also know of other global relations but translating them to better predictions requires careful modeling experiments.
• Researchers are also continuing to search for additional process understanding, especially for high-impact extreme rainfall events.
• A new study (of which the author was part) has found that despite all these seemingly disparate changes in different aspects of the monsoon dynamics, a remarkable stationary element exists in terms of where the synchronized extreme rainfall events occur.
• The so-called large-scale extreme rainfall events are simultaneous or near-simultaneous heavy rain episodes that are strewn across a ‘highway’ that extends from parts of West Bengal and Odisha to parts of Gujarat and Rajasthan.
• The most remarkable new finding is that this corridor has remained unchanged from 1901 to 2019.
• In the seemingly chaotic change in all aspects of the monsoon, such trapping of the extreme events to a relatively narrow corridor is good news for potential improvements in process understanding, which is bound to lead to better predictions of these synchronized extreme rainfall events.

What does this mean for the monsoon’s stability?

• Traditional statistical methods tend to miss the complex relations between multiple nodes of rainfall centers.
• Rainfall data from the IMD at a 25-km scale in latitude and longitude offers a rich field over which sophisticated network analysis can be applied to extract the nodes that have the highest synchronicity in rainfall with other nodes near and far.
• This analysis — applied in this study — found that the most active nodes have followed this ‘highway’ for more than a century.
• The link lengths between nodes, or the scales of synchronicity, have remained nearly constant, at an average value of about 200 km.
• We can use a popcorn and kettle analogy here to understand this better. Central India is the kettle that warms up from the pre-monsoon into the monsoon.
• The monsoon rainfall systems are like kernels of corn popping randomly across the kettle.
• But it turns out that the kernels are popping in a synchronous dance, an indication that large groups of popcorn are jumping up at the same time.
• An analysis of winds and other circulation features indicates that the monsoon domain has been unique in remaining fairly stable for the formation of these extremes despite the various kicks from all tropical oceans and from pole to pole.

What do the findings mean for forecasts?

• Some researchers have said that stationary elements no longer exist in climate systems because of global warming.
• Yet the Indian monsoon continues to produce surprises in the way it can synchronize heavy rain events as well as stick to the ‘highway’ for such a long time.
• This is also the corridor for the monsoon depressions, which themselves have shown an increase at the 3- to 10-day timescales while decreasing at lower frequencies of 10-60 days.
• These changes are manifest in the active and break periods, as stated above.
• The main candidate for the geographic trapping of synchronized extreme rainfall is likely to be the range of mountains running along the west coast and across Central India.
• This hypothesis needs to be tested in models, but its implications for improving forecasts of such events are undeniable.
• The finding also suggests that to improve forecasts, increasing the model resolution and the computational cost may not be necessary.
• Instead, the focus can be on the dynamics of synchronization.
• The potential for reducing risk at a smaller scale from these large-scale extreme rainfall events, for agriculture, water, energy, transportation, health, etc., is also alluring.
• Fortunately, India is in a solid position vis-à-vis its modeling capacity and computational resources to fully exploit this potential.

Socotra Archipelago

 Days into COP28 in Dubai, one little-known archipelago has come into sharp relief: Socotra.

• Composed of four small Yemeni islands, Socotra has been in the sights of the United Arab Emirates (UAE) ever since the civil war in Yemen erupted in September 2014.

What is an Archipelago?

• An archipelago is an area that contains a chain or group of islands scattered in lakes, rivers, or the ocean.

Types of Archipelagos

Oceanic islands

• Most archipelagos are formed when volcanoes erupt from the ocean floor, called oceanic islands.
• For example, the Hawaiian archipelago islands were formed by a series of volcanic eruptions that began more than 80 million years ago and are still active today.

Coral cay archipelago

• Archipelagos can also form due to erosion, sedimentary deposits, rising sea level, and other geographic processes.
• The Florida Keys are an example of a coral cay archipelago, which forms when ocean currents transport sediments that gradually build up on the reef surface.

Continental fragments

• Continental fragments are archipelagos that have separated from a continental land mass due to the Earth’s tectonic movements.
• The Farallon Islands off the coast of California are an example of continental fragments.

• The largest archipelago in the world was formed by glacial retreat.
• The Malay Archipelago, between the Pacific and Indian Oceans, contains more than 25,000 islands in Southeast Asia.
• The thousands of islands of Indonesia and Malaysia are a part of the Malay Archipelago.
• At least some of these islands—and the straits that separate them—were part of mainland Asia during the last ice age.

Socotra Archipelago

• The Socotra Archipelago is located off the Horn of Africa, at the crossroads between the Red Sea and the Indian Ocean.
• It is recognized as a regional centre of biodiversity, with spectacular endemic species such as the Dragon Blood Tree (Dracaena cinnabari).
• Socotra has a rich cultural heritage, including the unique Soqotri language.
• Known for its unique and abundant wildlife, Socotra was believed to be the original location of the Garden of Eden.
• The archipelago is listed as a UNESCO World Heritage site to protect what is considered one of the world’s most biodiverse and distinctive islands.
• Naturalists and environmentalists estimate that 37 percent of 825 plant species, 90 percent of its reptiles, and 95 percent of its land snails exist nowhere else in the world.
• The archipelago is increasingly in the UAE’s sights because of its strategic location between the navigable waterways of the Gulf, Africa and Asia.
• It’s a potential linchpin for shipping, logistics and military defence or projection, and could allow the UAE to advance its geostrategic goals while countering those of competitors and adversaries.
• The Emirates are also thought to be eyeing Socotra for its touristic development potential and this would represent a sure threat to the archipelago’s biodiversity.
• Socotra has high importance for bird species as underlined by the identification by Birdlife International of 22 Important Bird Areas on Socotra.
• Socotra also supports globally significant populations of other land and sea birds, including several threatened species.
• The marine life of Socotra is also very diverse, with 253 species of reef-building corals, 730 species of coastal fish and 300 species of crab, lobster and shrimp.

Saiga antelope

    The status of Saiga antelope (Saiga tatarica) in the International Union for Conservation of Nature (IUCN) Red List has been changed from critically endangered to near threatened.

Saiga Antelope

• The Saiga antelope (Saiga tatarica and S. borealis mongolica) is a large migratory herbivore of Central Asia found in Kazakhstan, Mongolia, the Russian Federation, Turkmenistan, and Uzbekistan. The saiga generally inhabits open dry steppe grasslands and semi-arid deserts. This antelope has an extremely unusual appearance with an over-sized and flexible nose, the internal structure of which acts like a filter. During the summer it filters out a dust kicked up by the herd and during the winter warms up the freezing air before it is taken into the lungs. In the spring large herds of female saiga gather and migrate to the breeding areas. In the summer the herds break into the smaller groups and from the autumn they gather again to move to the winter grounds. The length of the journeys varies depending on the weather and forage conditions.  However, it may reach up to 1,000 km a year. Their migration route typically follows a north-south direction. However, it also has a nomadic pattern.
• The saiga population in the 1990s underwent a catastrophic fall (~95%) in numbers decreasing from more than 1.5 million to 50,000 individuals across its range. Such a drastic decline happened because of poaching. As saiga horns are highly valued in traditional Chinese medicine the illegal trade became more widespread due to the hard economic conditions and impoverishment of the local human population and weaker control after the dissolution of the Soviet Union.
• There are currently five subpopulations of saiga. The largest population inhabits central Kazakhstan (Betpak Dala), the second largest group is found in the Urals in Kazakhstan and Russian Federation, others belong to Kalmykia in the Russian Federation and the Ustyurt Plateau region in southern Kazakhstan and north-western Uzbekistan.
• The population of Mongolian saiga occurs in the west of the country. The current population numbers total about 200,000 saigas in all the subpopulations combined. Poaching persists as a key threat, as demand for saiga horns remains high and they are illegally sold on the black market.
• A rise of mass mortality probably due to diseases (occurring annually from 2010) poses yet another threat. Lastly, the development of extractive industries and related infrastructure development causes fragmentation and degradation of saiga habitats. A prominent feature of the saiga is the pair of closely spaced, bloated nostrils directed downward.
• Other facial features include the dark markings on the cheeks and the nose and the long ears.
• During summer migrations, a saiga''s nose helps filter out dust kicked up by the herd and cools the animal''s blood. In the winter, it heats up the frigid air before it is taken to the lungs.
• Only males possess horns.
• Saigas form very large herds that graze in semideserts, steppes, grasslands, and possibly open woodlands, eating several species of plants, including some that are poisonous to other animals.
• They can cover long distances and swim across rivers, but they avoid steep or rugged areas.
• Poaching on an industrial scale has contributed significantly to the saiga’s dramatic decline, but it is by no means the only factor.
• Habitat loss and fragmentation, catastrophic disease outbreaks and increasingly restricted access to historical migration routes have also taken a heavy toll.

Demaorchestia alanensis

 Researchers at Berhampur University, Odisha have discovered a new species of marine amphipod — a shrimp-like crustacea of genus Demaorchestia— in the state’s Chilika lake on the east coast of India.

• The study has revealed that the new species is white in colour and less than 15 millimetres in length. It has 13 pairs of legs. While three pairs are used for swimming in the water, eight pairs are used for walking on land. The other two pairs are used for capturing prey and feeding.
• The species can be distinguished from the other members of the genus by two to three strong, hair-like structures or setae on the anterior margin of the propodus of the gnathopod. It belongs to the subfamily Platorchestiinae found along the Indian coast.
• Amphipods are a significant group in the marine ecosystem and play a vital role in the marine food chain. They also serve as indicators for studying the impact of climate change and health of coastal ecosystems, he said. Further research will delve deeper into understanding the specific ecological roles of amphipods in coastal and marine environments.

FAO Report

The report from the Food and Agriculture Organization of the United Nations (FAO) sheds light on the state of food security and nutrition in the Asia Pacific region, focusing particularly on India, Pakistan, and Bangladesh.

Key Highlights of the Report

• The Food and Agriculture Organization (FAO) of the United Nations recently released a report titled "Regional Overview of Food Security and Nutrition 2023: Statistics and Trends," painting a concerning picture of food access and nutritional well-being in India and the broader Asia Pacific region.

Food Affordability

• Over 74% of Indians struggled to afford a healthy diet in 2021, demonstrating a significant portion of the population remains vulnerable to rising food costs. The slight decrease compared to 2020 (76.2%) offers a glimmer of hope, but the overall figure remains alarming.
• Rising income inequality and inflation further exacerbate the affordability issue, creating a vicious cycle of poverty and malnutrition.

Undernourishment

• 6% of India''s population suffers from undernourishment, translating to economic and social burdens. This statistic underlines the need for robust social safety nets, targeted interventions, and improved access to nutritious food.
• Addressing undernourishment requires focusing on maternal health and nutrition, promoting diverse and healthy diets, and tackling poverty.

Food Insecurity

• While the region''s prevalence of food insecurity is lower than the global average, disparities exist. Southern Asia faces higher rates compared to Eastern Asia, highlighting the need for regionalized approaches to food security.
• Persistent hunger and food insecurity threaten human development and stability, requiring urgent action to strengthen food systems and improve access.

Child Health

• 7% of Indian children under five suffer from stunting, reflecting inadequate maternal health and nutrition, poor feeding practices, and repeated infections.
• The high rate of wasting (18.7%) and overweight (2.8%) further underscores the need for comprehensive child health programs and improved nutritional education.
• Addressing these challenges requires promoting early childhood development, advocating for exclusive breastfeeding, and providing access to diverse and healthy foods for children.

Maternal Health

• A staggering 53% of women in India aged 15-49 have anaemia, raising concerns about maternal and neonatal health. This prevalence indicates inadequate dietary intake of iron and other essential nutrients, highlighting the need for targeted interventions and improved access to iron-rich foods and supplements.
• Addressing anaemia requires promoting dietary diversification, improving access to healthcare, and empowering women to make informed choices about their health and nutrition.

Positive Developments

• The slight decrease in the food affordability gap, though small, offers a ray of hope and suggests targeted interventions could yield further improvements.
• India''s progress in exclusive breastfeeding (63.7%) surpasses the global average and signifies commendable efforts in promoting early childhood nutrition.

Challenges and the Way Forward

• Rising food costs and stagnant incomes remain significant threats to food affordability and require multifaceted solutions, including income generation opportunities and price stabilization mechanisms.
• Addressing regional disparities in food insecurity demands tailor-made interventions for each subregion, considering their unique vulnerabilities and strengths.
• Tackling child malnutrition requires holistic approaches focusing on maternal health and nutrition, early childhood development, and improved access to diverse and healthy foods.
• Combating anaemia in women necessitates dietary diversification, improved access to healthcare, and empowering women to make informed choices about their health and nutrition.

• The FAO report highlights persistent challenges in food security, nutrition, and access to healthy diets in the Asia Pacific region, emphasizing the need for sustained efforts to meet global nutrition goals, especially in addressing the root causes of undernourishment, inadequate nutrition, and health risks faced by vulnerable populations, particularly women and children.

Article 356

The Supreme Court ruled that the actions of the President during a state emergency under Article 356 must have a "reasonable nexus" with the stated objectives.

• The Supreme Court held that the declaration of a State emergency under Article 356 and the subsequent actions of the President should have a "reasonable nexus." This implies that there should be a logical connection or justification between the emergency declaration and the actions taken.
• The court emphasized that the actions of the President during the state emergency are subject to judicial scrutiny. This means that the court can examine whether the President''s exercise of power was in line with the constitutional provisions and had a reasonable connection to the stated objectives.

Article 356

• Article 356 of the Indian Constitution, commonly known as President''s Rule or State Emergency, provides a mechanism for the Central government to assume control over a state''s administration if there''s a failure of constitutional machinery in that state.
• The origin of Article 356 can be traced back to the Government of India Act 1935, which gave similar powers to the Governor-General to intervene in the affairs of the provinces.
• The framers of the Constitution adopted this provision with some modifications, hoping that it would be used sparingly and only in extreme cases. However, over the years, Article 356 has been invoked more than a hundred times, often for political reasons rather than constitutional crises.

Provisions of Article 356

Grounds for Imposition

• If the President, upon receiving a report or otherwise, is satisfied that the government of a state cannot be carried out in accordance with the Constitution, Article 356 can be invoked.
• Also, if a state fails to comply with or give effect to the directions from the Centre, it can be seen as a failure of the constitutional machinery.

Parliamentary Approval and Duration

• A proclamation of President''s Rule must be approved by both Houses of Parliament within two months.
• If approved, it continues for six months initially and can be extended, with Parliamentary approval, up to three years in total.

• However, post the 44th Amendment Act of 1978, the extension beyond one year requires specific conditions, such as the existence of a National Emergency and certification by the Election Commission for the inability to hold state elections.

• The President can revoke the proclamation at any time without parliamentary approval.

Consequences of President''s Rule

• The President takes over the state''s functions, can declare that state legislature powers are vested in the Parliament, and suspend or dissolve the state legislative assembly.
• During this period, the President or Parliament can make laws for the state, which continue even after the President''s Rule unless altered by the state legislature.

Supreme Court Intervention

• In S. R. Bommai Case (1989), the Supreme Court clarified the limitations of Article 356.

• It restricted the use of Article 356 to only instances of a breakdown in constitutional machinery or ''hung assembly.''
• It emphasized that the provision cannot be invoked without giving the state government an opportunity to prove its majority or in the absence of a violent breakdown of the constitutional machinery.

• The Supreme Court''s intervention significantly curtailed the arbitrary use of Article 356, emphasizing the importance of following constitutional norms before imposing the President''s Rule.

• Article 356 was originally intended to address severe breakdowns in governance within states but has faced misuse for political gains. The Supreme Court''s intervention in the S. R. Bommai case set clear guidelines to restrict its arbitrary use, emphasizing adherence to constitutional principles and the democratic process.

SR Bommai judgment

 The SR Bommai judgment played a significant role in the Supreme Court''s recent verdict on Article 370, particularly regarding the legality of the President''s rule in Jammu and Kashmir during the abrogation process.

• The SR Bommai judgment, delivered by a nine-judge bench of the Supreme Court in 1994, is a landmark case that interpreted Article 356 of the Indian Constitution, which deals with the imposition of President''s rule in states.
• The case has significance in understanding the Supreme Court''s approach to the relationship between the central government and state governments, particularly in the context of dismissing state governments and imposing the President''s rule.
• In 1989, the Union government dismissed the Karnataka state government by imposing the President''s rule. The dismissal was based on the grounds that the Chief Minister, SR Bommai, did not command a majority, and no other political party was in a position to form the government. However, the move was controversial, and the Governor did not ascertain Bommai''s view before making his report to the President.

Key Rulings of the Bommai Case

• The power of the President under Article 356 is not absolute, but subject to judicial review on certain grounds.
• The President should exercise this power only when there is a breakdown of constitutional machinery in a state, not on account of political instability or maladministration.
• The President should act based on objective material and not on mere advice or opinion of the Governor or the central government.
• The President should give an opportunity to the state government to explain its position and prove its majority before taking any action.
• The President should not dissolve the state assembly until both Houses of Parliament approve his proclamation.
• The floor test is the only conclusive test to determine whether a state government enjoys majority support or not.
• The court can restore the dismissed state government and revive the dissolved assembly if it finds that the President''s action was unconstitutional or mala fide.

Relevance to J&K and Article 370

• In the context of the recent Supreme Court verdict on Article 370 and the abrogation of special status in Jammu and Kashmir, the Bommai judgment was relied upon. The key question was whether Article 370 could be abrogated when the state was under President''s rule.
• The Supreme Court, drawing from the Bommai ruling, held that the actions of the President in consenting to the revocation of J&K''s special status were constitutionally valid. The Court asserted that the Bommai ruling established that actions taken by the President after issuing a proclamation were subject to judicial review.

• The Bommai judgment, which defined the limitations and procedures for the imposition of the President''s rule, played a crucial role in shaping the Supreme Court''s perspective on the constitutional validity of actions taken during the President''s rule, including the revocation of special status in Jammu and Kashmir.

Exchange-Traded funds

 The Minister of State in the Labour Ministry has highlighted in the Lok Sabha that the Employees’ Provident Fund Organisation (EPFO) has invested a total of more than Rs 2.5 trillion in exchange-traded funds (ETFs) over the past seven years.

• The EPFO uses Exchange-traded funds (ETFs) to invest in equity markets, indirectly gaining exposure to a diversified portfolio of stocks.
• Initially investing 5% of its corpus in ETFs, the EPFO later raised this limit to 15%, possibly due to the perceived benefits of ETF investments and the potential for higher returns.
• The EPFO''s overall investment corpus has shown a healthy growth rate of 16.7% in the fiscal year 2022-23, indicating successful management and possibly favourable market conditions.
• By investing in ETFs instead of individual stocks, the EPFO potentially mitigates the risks associated with stock-picking while benefitting from the broader market movements.

Exchange-traded funds (ETFs)

• Exchange-traded funds (ETFs) are a popular type of investment that offers many benefits to investors.
• ETFs are collections of securities, such as stocks, bonds, commodities, or currencies that track an underlying index or market. ETFs trade on stock exchanges, just like individual stocks, and can be bought and sold throughout the day.

Advantages

• Diversification: ETFs allow investors to gain exposure to a wide range of markets, sectors, regions, or themes with a single purchase. This reduces the risk of investing in a single company or asset class.
• Low cost: ETFs typically have lower fees and expenses than mutual funds or other actively managed funds. ETFs also have lower trading costs, as they do not incur commissions or sales charges when bought or sold.
• Tax efficiency: ETFs are generally more tax-efficient than mutual funds, as they do not distribute capital gains to shareholders. Instead, investors only pay taxes when they sell their ETF shares, which gives them more control over their tax situation.
• Transparency: ETFs disclose their holdings and performance on a daily basis, which allows investors to see exactly what they are investing in and how their ETF are performing. ETFs also follow clear and consistent rules for selecting and weighting their holdings, which reduces the risk of manager bias or style drift.
• Flexibility: ETFs can be used for various investment strategies and objectives, such as income generation, hedging, asset allocation, or speculation. ETFs can also be traded using various methods, such as limit orders, stop orders, or margin trading.

Disadvantages

• Market risk: ETFs are subject to the same market fluctuations and volatility as the underlying securities they hold. If the market declines, so will the value of the ETF.
• Tracking error: ETFs may not perfectly replicate the performance of their underlying index or market, due to fees, expenses, liquidity issues, or rebalancing. This means that the ETF may underperform or outperform its benchmark over time.
• Liquidity risk: ETFs may experience low trading volume or wide bid-ask spreads, which can affect their liquidity and price. This can make it difficult for investors to buy or sell their ETF shares at a fair price.
• Counterparty risk: Some ETFs use derivatives, such as swaps or futures contracts, to achieve their investment objectives. This exposes them to the risk that the counterparty to the derivative contract may default or fail to honour its obligations.
• Regulatory risk: ETFs are subject to changing laws and regulations that may affect their structure, operation, or taxation. This can create uncertainty and complexity for investors and issuers.

Non-Convertible Redeemable Preference Shares (NCRPS)

The Securities and Exchange Board of India (SEBI) proposes reducing the face value of non-convertible debentures (NCDs) and non-convertible redeemable preference shares (NCRPS) from Rs 1 lakh to Rs 10,000.

• The Securities and Exchange Board of India (SEBI) has proposed significant changes to the issuance of non-convertible debentures (NCDs) and non-convertible redeemable preference shares (NCRPS) to enhance the participation of non-institutional investors in the corporate bond market and to manage associated risks.

Key points from the SEBI proposal

Reduced Face Value

• SEBI has suggested permitting companies to issue NCDs and NCRPS with a face value of Rs. 10,000, as opposed to the existing system of Rs. 1 lakh face value.
• The rationale behind this is to make the securities more accessible to non-institutional investors by reducing the entry barrier imposed by the high face value.

Risk Mitigation Measures

• To safeguard the interests of non-institutional investors, SEBI proposes that these NCDs and NCRPS should be "plain vanilla" instruments with a simple structure. They should not have complex features such as credit enhancements or structured obligations.
• The issuer must appoint a merchant banker to conduct due diligence for the issuance and disclosures should be made in the private placement memorandum.

Online Bond Platforms (OBPs)

• The proposal aligns with the introduction of a regulatory framework for online bond platforms. SEBI notes that a substantial portion of investors on these platforms comprises non-institutional investors.
• The reduction in face value is seen as a measure to further increase participation, especially among non-institutional investors.

Previous Face Value Reduction

• SEBI had already reduced the face value of debt securities and NCRPS from Rs. 10 lakh to Rs. 1 lakh in October 2022. This move was intended to encourage non-institutional investors to participate in the corporate bonds market.

Investor Participation

• The paper highlights that during the period from July to September 2023, non-institutional investors subscribed to 4% of the total amount raised, compared to the general average of less than 1%.
• SEBI attributes this increase in participation to the earlier reduction in face value and the mainstreaming of online bond platforms.

QR Code for Listed NCDs

• Issuers with listed outstanding NCDs are proposed to include a QR code in the offer document.
• Scanning the QR code would open a web link to the audited financials for the last three financial years and stub period financials on the stock exchange''s website.

• These proposed changes aim to make the corporate bond market more inclusive, especially for non-institutional investors, while also ensuring necessary risk mitigation measures are in place. The reduction in face value and the integration of online bond platforms are seen as key strategies to achieve these goals.

Status of Election Commission of India (ECI) members

A Bill introduced in the Rajya Sabha faces criticism for diminishing the status of Election Commission of India (ECI) members from that of a Supreme Court judge to that of the Cabinet Secretary; however, amendments proposed aim to reinstate their previous status.

• The Indian Constitution doesn''t specify the appointment process for the Chief Election Commissioner (CEC) and Election Commissioners (ECs).

• Currently, the president appoints the CEC and ECs based on the recommendation of a selection committee, comprising the prime minister, a union cabinet minister, and the leader of the opposition or the leader of the largest opposition party in the Lok Sabha.

• In March 2023, a five-judge Constitution Bench of the Supreme Court ruled that the Chief Election Commissioner (CEC) and Election Commissioners (ECs) should be appointed by a committee comprising the Prime Minister, Leader of Opposition in Lok Sabha, and the Chief Justice of India (CJI).
• The government, in response to the court verdict, introduced The Chief Election Commissioner and Other Election Commissioners (Appointment, Conditions of Service and Term of Office) Bill, 2023.

Provisions of the Bill

• The Bill proposed a committee for the appointment of the CEC and ECs, consisting of the Prime Minister, the Leader of the Opposition, and a Cabinet Minister nominated by the Prime Minister (instead of the CJI as suggested by the Supreme Court).
• The Bill also suggested giving the CEC and ECs the same salary, perks, and allowances as that of the Cabinet Secretary.
• The proposed Bill aimed to replace The Election Commission (Conditions of Service of Election Commissioners and Transaction of Business) Act, 1991, which currently equates the salaries of the CEC and ECs with that of a Supreme Court judge.

Criticism

• Opposition leaders criticized the Bill for replacing the CJI with a Cabinet Minister in the selection committee, potentially giving the government majority influence over the appointment process.
• The main concern raised by current and former ECI officials was the perceived downgrading of the status of the ECI. The change in status from that of a Supreme Court judge to that of a government official could affect the ECI''s ability to summon officials and Ministers.

Recent Amendments

• The Bill was not taken up for discussion during the Monsoon Session but has been listed for consideration and passing. Key amendments are expected to be moved by the Law Minister, to address the concerns raised.
• The proposed amendments aim to restore the equivalence of the status of the EC with that of a Supreme Court judge, maintaining the same salary, dearness allowance, and leave encashment rules.

• The Bill has been criticized for potential changes in the appointment process and the perceived downgrading of the status of members of the ECI. Amendments are expected to be introduced to address these concerns and restore the equivalence of the ECI''s status with that of a Supreme Court judge.

Javier Milei''s victory in Argentina

 Javier Milei''s victory in Argentina''s presidential elections has brought the term “anarcho-capitalism” into the spotlight, sparking debates around its principles and feasibility.

• Anarcho-capitalism is a political philosophy that advocates for the abolition of the state and the provision of law and order through private companies in a free market.
• The ideology has gained attention, particularly with figures like Javier Milei winning the presidential elections in Argentina.

How Anarcho-Capitalism Works:

Private Provision of Services

• Traditional free-market advocates believed that some services, like police and courts, could only be provided by the state. Anarcho-capitalists challenge this idea, asserting that private companies in a free market can offer policing and legal services more efficiently.

Competition in the Market

• Anarcho-capitalists argue that, similar to how private companies offer goods and services more efficiently than the government, competition in the market for policing and legal services would lead to higher quality and lower prices.

Customer Accountability

• In an anarcho-capitalist society, individuals would pay private police and courts for protection and dispute resolution. Advocates argue that customer patronage would ensure accountability, as dissatisfied customers could switch to competing services.

Criticisms of Anarcho-Capitalism

Feasibility and Conflict

• Critics argue that having multiple private firms provide police and legal services within a single region could lead to disagreement and conflict, with armed private entities protecting their paying clients, potentially causing chaos.

Bias toward the Rich

• Critics contend that anarcho-capitalism might favour the rich, as those with more financial resources could potentially manipulate private police and courts to escape justice, leaving the poor without protection.

Anarcho-Capitalist Responses to Criticisms

Cooperation and Common Rules

• Anarcho-capitalists argue that private police and courts, seeking long-term profits, would likely cooperate and agree to common rules to avoid costly conflicts. Cooperation would be necessary to prevent a situation where one firm defends a criminal against another firm''s client.

Market Dynamics and Justice for the Poor

• Anarcho-capitalists assert that private firms, reliant on broad societal patronage, would not disproportionately favour the rich. They argue that the poor might have better chances of obtaining justice in a competitive market, where firms seek to satisfy the demands of a larger customer base.

The debates around anarcho-capitalism involve fundamental questions about the role of the state, the feasibility of private provision of essential services, and the potential implications for social justice. While anarcho-capitalists emphasize the efficiency and accountability of private markets, critics raise concerns about conflict, inequality, and the practical challenges of implementing such a system.
