Background: InvITs and REITs are new concepts in the Indian market but have been a popular choice globally for their lucrative returns and capital appreciation. About Infrastructure Investment Trust (InvITs) An Infrastructure Investment Trust (InvITs) is a Collective Investment Scheme similar to a mutual fund. It enables direct investment of money from individual and institutional investors in infrastructure projects to earn a small portion of the income as return. ( FPI and InvITs) The InvIT is designed as a tiered structure with Sponsor setting up the InvIT which in turn invests into the eligible infrastructure projects either directly or via special purpose vehicles (SPVs). Regulated by: SEBI (Infrastructure Investment Trusts) Regulations, 2014. An InvIT has four parties namely: Trustee, Sponsor(s) and Investment Manager and Project Manager. While the trustee (certified by Sebi) has the responsibility of inspecting the performance of an InvIT, sponsor(s) are promoters of the company that set up the InvIT. Types of InvITs As per current SEBI Regulations InvITs can be divided into 5 key types depending on the types of infrastructure they own or operate: Energy such as power generation and distribution. Transport & Logisticsg. operating highways and other toll roads optical fiber networks and telecom towers Social and Commercial Infrastructure g. parks Water and Sanitationg. irrigation networks From the perspective of the source of funds, InvITs can be of two types: Privately-Held InvITs:- This type of InvIT is not listed on the stock exchange and units of this type of infrastructure trust cannot be bought or sold on a stock exchange. All units of this type of unit are held privately by a very limited number of individuals or institutions. Public-Listed InvITs:- After an Infrastructure Trust lists itself on the stock exchange, it is known as a public-listed InvIT. Units of a public-listed InvIT can be bought and sold on stock exchanges by retail as well as institutional investors. Current SEBI regulations do not require a mandatory listing of InvITs on stock exchanges.

Background: Petitions challenge the right of state governments to levy taxes on mining activities within their respective territories. The crux of the dispute lies in the distinction between royalty charged on mining and taxes imposed by states. About MINES AND MINERALS DEVELOPMENT AND REGULATION ACT (MMDRA): The The Mines and Minerals (Development and Regulation) Act, 1957 forms the basic framework of mining regulation in India. The act is applicable to all minerals except minor minerals and atomic minerals. MMDR Act, 1957, mandate that every mining lease holder needs to pay royalty for major minerals removed or consumed. This royalty compensates for the privilege of extracting minerals from leased areas. The MMDR Act explicitly places the responsibility for mineral development and regulation within the purview of the Central Government. Central Government has the authority to specify the royalty rates for various minerals. The Second Schedule of the MMDR Act provides royalty rates for various minerals. Under the MDR Act, states have the authority to collect royalties. This provision ensures that mining activities contribute to state revenue while adhering to sustainable practices. It was amended in 2015 and 2016 to bring several reforms in the mineral sector.

Background: According to their recent ruling, the assessee is eligible to claim credit for MAT under the Vivad se Vishwas (VSV) Scheme for the relevant assessment year. This decision could have significant implications for taxpayers seeking resolution of their tax disputes. About MINIMUM ALTERNATE TAX (MAT): Minimum Alternate Tax (MAT) is a provision in India’s Income Tax Act. MAT ensures that companies contribute a minimum amount of tax, regardless of their tax exemptions and deductions. MAT was introduced to bring “zero tax companies” into the tax net. It applies to domestic companies, foreign companies operating in India and Special Economic Zone units. The tax is calculated based on the normal income tax liability of the company or entity. MAT ensures tax fairness and prevents companies from completely avoiding taxes. The Vivad se Vishwas (VSV) Scheme aims to provide a mechanism for taxpayers to settle pending income tax disputes and avoid prolonged litigation. By allowing credit for MAT under this scheme, the Income Tax Appellate Tribunal (ITAT) is acknowledging the importance of providing relief to taxpayers and promoting a more efficient resolution process.

Background:- Over 11.3 million cases settled in first National Lok Adalat of 2024.Figures show the effectiveness of alternative mechanisms for dispute resolution. About Lok Adalat Lok Adalat is one of the alternative dispute redressal mechanisms, it is a forum where disputes/cases pending in the court of law or at pre-litigation stage are settled/ compromised amicably. Lok Adalats have been given statutory status under the Legal Services Authorities Act, 1987 Under the said Act, the award (decision) made by the Lok Adalats is deemed to be a decree of a civil court and is final and binding on all parties and no appeal against such an award lies before any court of law. If the parties are not satisfied with the award of the Lok Adalat though there is no provision for an appeal against such an award, but they are free to initiate litigation by approaching the court of appropriate jurisdiction by filing a case by following the required procedure, in exercise of their right to litigate. There is no court fee payable when a matter is filed in a Lok Adalat. If a matter pending in the court of law is referred to the Lok Adalat and is settled subsequently, the court fee originally paid in the court on the complaints/petition is also refunded back to the parties. The persons deciding the cases in the Lok Adalats are called the Members of the Lok Adalats, they have the role of statutory conciliators only and do not have any judicial role; therefore they can only persuade the parties to come to a conclusion for settling the dispute outside the court in the Lok Adalat and shall not pressurize or coerce any of the parties to compromise or settle cases or matters either directly or indirectly. Disputes before Lok Adalat would be decided on the basis of the compromise or settlement between the parties. The members shall assist the parties in an independent and impartial manner in their attempt to reach amicable settlement of their dispute. National Lok Adalat National Level Lok Adalats are held for at regular intervals where on a single day Lok Adalats are held throughout the country, in all the courts right from the Supreme Court till the Taluk Levels wherein cases are disposed off in huge numbers. Permanent Lok Adalat The other type of Lok Adalat is the Permanent Lok Adalat, organized under Section 22-B of The Legal Services Authorities Act, 1987. Permanent Lok Adalats have been set up as permanent bodies for providing compulsory pre-litigative mechanism for conciliation and settlement of cases relating to Public Utility Services like transport, postal, telegraph etc. Here, even if the parties fail to reach to a settlement, the Permanent Lok Adalat gets jurisdiction to decide the dispute, provided, the dispute does not relate to any offence.

Background:- When taken even in small quantities for many years, Rhodamine B can cause a lot of health problems including cancers. About Rhodamine B:-   Rhodamine-B is a fluorescent dye used in cosmetics, textile and leather industries. It gives you brilliant pinks, greens and blues. Unfortunately, it is used as a food colouring agent not only in cotton candy but also in the preparation of sweets, various manchurian items and pakodas and in the preparation of sauces for Chinese food. Rhodamine-B has been routinely used in many coloured foods such as cotton candy to make it look appealing and attractive to young persons and children. Studies have shown that Rhodamine-B can cause cell death. In long-term use, it can damage the cerebellum tissue and brainstem. There is recent evidence that it damages the kidney, liver and increases the risk of stomach tumour. It is toxic to the human body and is a carcinogen. FSSAI has approved certain food colours and flavors as safe for consumption. These include: Caramel, Riboflavin (Lactoflavin), Saffron, Annatto, Curcumin (Turmeric), Carotene and carotenoids, including Beta-carotene, red colour from Ponceau 4R, Carmoisine, and Erythrosine, yellow colour (Tartrazine and Sunset Yellow FCF), blue colour (Indigo Carmine and Brilliant Blue FCF) and green colour (Fast Green FCF). Source: The Hindu One Nation, One Election Syllabus Prelims and Mains – Polity Context: The High-level Committee (HLC) on One Nation, One Election submitted its report to President Droupadi Murmu on Thursday (March 14) morning. Background: HLC was chaired by former president Ram Nath Kovind. What is meant by simultaneous elections? Simultaneous elections, popularly referred to as “One Nation, One Election”, means holding elections to Lok Sabha, all state Legislative Assemblies, and urban and rural local bodies (municipalities and panchayats) at the same time. Currently, all these elections are held independently of one another, following timelines dictated by the terms of every individual elected body. Simultaneous elections for Lok Sabha and state assemblies used to happen in India until the fourth general elections of 1967. However, as successive central governments used constitutional provisions to dismiss state governments before the end of their term, and as coalition governments in the states and the Centre kept collapsing, country came to see elections at different times through the year. According to the HLC report, the country now sees five to six elections in a year — if municipalities and panchayat elections are also included, the number of elections will increase manifold. What is the need for holding simultaneous elections? Frequent elections burden the government exchequer with additional expenditure. If the expenditure incurred by political parties is also added, these figures will be even higher. Asynchronous elections cause uncertainty and instability, thwarting supply chains, business investments and economic growth. Disruption of government machinery due to asynchronous elections causes hardship to citizens. Frequent use of government officials and security forces adversely affect discharge of their duties. Frequent imposition of the Model Code of Conduct (MCC) causes policy paralysis and slows down the pace of the developmental programmes. Staggered elections induce ‘voters’ fatigue’ and present a significant challenge in ensuring their participation. Important  recommendations of HLC AMENDING THE CONSTITUTION: The Constitution should be amended to enable simultaneous elections in two steps.In the first step, simultaneous elections will be held to Lok Sabha and State Assemblies. For this, no ratification by the states will be required for the constitutional amendment.In the second step, elections to municipalities and the panchayats will be synchronised with elections to Lok Sabha and state Assemblies in such a way that local body elections are held within 100 days of the elections to Lok Sabha and state Assemblies. This will require ratification by not less than one-half of the states. SINGLE ELECTORAL ROLL AND ELECTION ID: For the purpose of preparation of single electoral roll and electoral photo identity cards for use in elections to all the three tiers of government, the Constitution should be amended, so that the Election Commission of India can prepare a single electoral roll and election ID in consultation with the State Election Commissions. These amendments will require ratification by not less than one-half of the states. SINGLE ELECTORAL ROLL AND ELECTION ID: For the purpose of preparation of single electoral roll and electoral photo identity cards for use in elections to all the three tiers of government, the Constitution should be amended, so that the Election Commission of India can prepare a single electoral roll and election ID in consultation with the State Election Commissions. These amendments will require ratification by not less than one-half of the states.

Background:- The growing tensions between Congo and Rwanda, which has been accused of supporting the rebels, have not only increased the risk of an all-out conflict but also pose a threat to food security for millions. About Democratic Republic of the Congo The Democratic Republic of the Congo is a country in Central Africa. By land area, the DRC is the second-largest country in Africa.The country has a 25-mile (40-km) coastline on the Atlantic Ocean but is otherwise landlocked. It is named after the Congo River, which flows through the country.The national capital and largest city is Kinshasa. The country is often referred to by its acronym, the DRC, or called Congo (Kinshasa), with the capital added parenthetically, to distinguish it from the other Congo republic, which is officially called the Republic of the Congo and is often referred to as Congo (Brazzaville). The country is bordered by the Republic of the Congo, Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania (across Lake Tanganyika), Zambia, Angola and the South Atlantic Ocean. The Democratic Republic of the Congo is extremely rich in natural resources (It boasts vast deposits of industrial diamonds, cobalt, and copper) but has suffered from political instability, lack of infrastructure, corruption, and centuries of both commercial and colonial extraction and exploitation. Congo River The Congo River , formerly also known as the Zaire River, is the second-longest river in Africa, shorter only than the Nile, as well as the third-largest river in the world by discharge volume, following the Amazon and Ganges rivers. It is the world’s deepest recorded river, with measured depths of around 220 m. It is the only major river to cross the Equator twice. The river and its tributaries flow through the Congo rainforest, the second largest rainforest area in the world.It drains into the Atlantic Ocean. Source: The Hindu Ethanol 100 or E100 Syllabus Prelims – Current Event Context: Shri Hardeep Singh Puri, Union Minister for Petroleum & Natural Gas and Housing and Urban Affairs, launched ‘ETHANOL 100. Background: ETHANOL 100 fuel has the potential to transform our transportation sector and reduce our dependence on fossil fuels. About Ethanol 100 OR E100: Contrary to popular belief, E100 fuel is not 100 percent ethanol. In accordance with specifications, E100 fuel includes 93-93.5 percent ethanol blended with 5 percent petrol and 1.5 percent co-solvent, which is a binder. Currently, E100 is priced the same as petrol — Rs 94.72/litre in Delhi, Rs 104.21/litre in Maharashtra and Rs 100.75/litre in Chennai. However, with wider adoption of the fuel, E100 will definitely be cheaper than petrol or diesel since ethanol is cheaper. In addition, the government’s keenness to provide a fillip to biofuels which help in crude oil import substitution is also likely to make it competitive in comparison to the conventional fuels. Ethanol is made from agricultural feedstock, which also provides income to farmers, making them a stakeholder in decarbonisation of the economy. E100 can be used as fuel in any flex fuel engine car. A flex fuel engine car is designed to run on a variety of fuels. It comes equipped with an internal combustion engine (ICE) which can run on petrol or ethanol or methanol, giving consumers choice at the point of sale of the fuel. ETHANOL 100 stands as a cleaner, greener alternative, boasting lower emissions of greenhouse gases and pollutants, thus aiding in combating climate change and enhancing air quality. With its high-octane rating, typically between 100-105, ETHANOL100 proves ideal for high-performance engines, ensuring improved efficiency and power output all while minimizing environmental impact. Source: PSU WATCH FLUORIDE CONTAMINATION Syllabus Prelims- Environment Context: Recently, Fluoride contamination was detected in three districts of Kerala. Background: According to the State Environment department, the source of contamination is likely geogenic, meaning these constituents are naturally present in the rock or soil matrix and enter groundwater through various chemical processes. About FLUORIDE CONTAMINATION Fluoride contamination in water is a critical issue worldwide. While fluoride is essential for dental health at low concentrations, excessive exposure can lead to health problems. Key Points: Essential Element: Fluoride is naturally present in water and certain foods. It plays a crucial role in preventing tooth decay. Threshold: However, when fluoride levels exceed 1.5 mg/L, it becomes toxic to humans. According to the Bureau of Indian Standards, the maximum permissible limit of arsenic in groundwater meant for drinking is 0.01 mg/l, while the corresponding limit of fluoride is 1.0 mg/l, which can be extended to 1.5 mg/l in case no alternative source of water is available. Health Impacts: Dental Fluorosis: Excessive fluoride causes dental fluorosis, characterized by staining, pitting, and weakening of tooth enamel. Skeletal Fluorosis: Chronic exposure leads to skeletal fluorosis, affecting bones and joints. Neurological Effects: High fluoride levels may impact the nervous system. Sources of Contamination: Geochemical Reactions: Fluoride leaches from rocks and soil into groundwater. Geological Factors: High fluoride content in specific geological formations. Anthropogenic Factors: Industrial processes, fertilizers, and mining contribute to contamination. Preventive Measures: Water Treatment: Implementing effective water treatment methods to reduce fluoride levels. Monitoring: Regular monitoring of fluoride content in drinking water. Awareness: Educating communities about safe water practices. Alternative Sources: Providing alternative water sources in affected areas. Endemic Areas: Certain regions are endemic for fluorosis due to natural geological factors. Balancing Act: Balancing the benefits of fluoride for dental health with the risks of toxicity is crucial. Other Pollutants that Affect Water Quality: Arsenic reaches groundwater through industrial and mining discharges, as well as fly ash ponds from thermal power plants. Chronic exposure to arsenic-contaminated water may lead to diseases such as black foot disease, diarrhea, lung cancer, and skin cancer. Certain regions in India have localized occurrences of elevated uranium concentrations in groundwater. Other elements that act as water pollutants include mercury (causing Minamata disease), cadmium (associated with Itai-Itai disease and nephritis), chromium (linked to lung cancer and reduced photosynthetic activities in plants), copper (causing various health issues), zinc, and lead (associated with anaemia, mental retardation, and other health problems).

Archives (PRELIMS & MAINS Focus)   Rising sea surface temperature Syllabus Prelims and Mains – Environment Context: The average global sea surface temperature (SST) — the temperature of the water at the ocean surface — for February 2024 stood at 21.06 degree Celsius, the highest ever in a dataset that goes back to 1979. Background:- The previous record of 20.98 degree Celsius was set in August 2023. Why are the oceans getting warmer? Since the Industrial Revolution kicked off in the 19th Century, human activities such as burning fossil fuels have released high levels of greenhouse gases (GHGs) in the atmosphere. Carbon dioxide, methane, ozone, and nitrous oxide are some of the notable GHGs, which essentially trap heat in the atmosphere and contribute to global warming. As a result, the average global temperature has risen at least 1.2 degree Celsius above pre-industrial times. Notably, almost 90 per cent of the extra heat trapped by GHGs has been absorbed by the oceans, making them steadily warmer over the decades. There are other factors which have led to a spike in ocean temperatures. For instance, El Niño — a weather pattern that refers to an abnormal warming of surface waters in the equatorial Pacific Ocean — has contributed to both ocean warming and rising global surface temperatures. There is also less dust blowing off the Sahara Desert recently due to weaker-than-average winds. Typically, the dust forms a “giant umbrella that shades” the Atlantic water and reduces ocean temperatures. Why are rising sea surface temperatures a cause of worry? Higher ocean temperatures can have irreversible consequences for marine ecosystems. For instance, warmer oceans lead to an increase in ocean stratification — the natural separation of an ocean’s water into horizontal layers by density, with warmer, lighter, less salty, and nutrient-poor water layering on top of heavier, colder, saltier, nutrient-rich water. Usually, ocean ecosystems, currents, wind, and tides mix these layers. The rise in temperatures, however, has made it harder for water layers to mix with each other. Due to this, oceans are able to absorb less carbon dioxide from the atmosphere and the oxygen absorbed isn’t able to mix properly with cooler ocean waters below, threatening the survival of marine life. Nutrients are also not able to travel up to the surface of the oceans from below. This could threaten the population of phytoplankton — single-celled plants that thrive on the ocean surface and are the base of several marine food webs. Phytoplankton are eaten by zooplankton, which are consumed by other marine animals such as crabs, fish, and sea stars. Therefore, if the phytoplankton population plummets, there could be a collapse of marine ecosystems. Warmer oceans cause marine heat waves (MHWs), which occur when the surface temperature of a particular region of the sea rises to 3 or 4 degree Celsius above the average temperature for at least five days. MHWs contribute to coral bleaching, which reduces the reproductivity of corals and makes them more vulnerable to life-threatening diseases. They also impact the migration pattern of aquatic animals. Higher ocean temperatures may also result in more frequent and intense storms like hurricanes and cyclones. Warmer temperatures lead to a higher rate of evaporation as well as the transfer of heat from the oceans to the air. When storms travel across hot oceans, they gather more water vapour and heat. This results in more powerful winds, heavier rainfall, and more flooding when storms reach the land — meaning heightened devastation.

Background: Scientists using data from the Ice Cube Neutrino Observatory in Antarctica believe they have potentially found the first evidence for astrophysical tau neutrinos, called “ghost particles”. About Ghost Particles: “Ghost Particles” is a nickname for neutrinos, which are tiny subatomic particles. They are often called ‘ghost particles’ because they barely interact with anything else. Key points about Neutrinos: Source: Neutrinos come from various sources and are often the product of heavy particles turning into lighter ones, a process called “decay”. Family: They belong to the family of particles known as leptons. There are three main leptons, namely electrons, muons, and tau particles. The last has proven to be especially difficult to observe and detect, earning the moniker of “ghost particle.” Characteristics: A neutrino is very similar to an electron, but has no electrical charge and a very small mass. They are the most common particle in the universe. Approximately 100 trillion neutrinos pass completely harmlessly through our body every second. Detection: They are extraordinarily difficult to detect, as they rarely collide with atoms. Of the four fundamental forces in the

Source: Hindu Businessline Anthropocene Syllabus Prelims – Science Context: An expert commission rejected a proposal to mark the start of the Anthropocene at a particular date. Background: The SQS-AWG is a commission responsible for recognising time units within our most recent period of geologic time. Its members have been looking into the question of formalising the Anthropocene Epoch as the youngest epoch, superposing the Holocene. On March 4, 2024, the commission, which consists of topical experts, rejected the proposal with a majority voting against it. About Anthropocene: Earth’s history is divided into a hierarchical series of smaller chunks of time, referred to as the geologic time scale. These divisions, in descending length of time, are called eons, eras, periods, epochs, and ages. These units are classified based on Earth’s rock layers, or strata, and the fossils found within them. From examining these fossils, scientists know that certain organisms are characteristic of certain parts of the geologic record. The study of this correlation is called stratigraphy. Officially, the current epoch is called the Holocene, which began 11,700 years ago after the last major ice age. However, the Anthropocene Epoch is an unofficial unit of geologic time, used to describe the most recent period in Earth’s history when human activity started to have a significant impact on the planet’s climate and ecosystems. The word Anthropocene is derived from the Greek words anthropo, for “man,” and cene for “new,” coined and made popular by biologist Eugene Stormer and chemist Paul Crutzen Scientists still debate whether the Anthropocene is different from the Holocene, and the term has not been formally adopted. The primary question that scientists needs to answer before declaring the Anthropocene an epoch is if humans have changed the Earth system to the point that it is reflected in the rock strata.

Background: Agniveers are a special group within the Indian Armed Forces, created under the Agnipath recruitment scheme. About AGNIPATH SCHEME The Agnipath Scheme is a short-service manpower model introduced by the Indian government for recruiting soldiers across the Army, Navy, and Air Force. It is a transformative initiative under the Ministry of Defence. Objective and Eligibility: The scheme aims to provide an opportunity for patriotic and motivated youth to serve in the Armed Forces. It applies to personnel below officer ranks, excluding commissioned officers. Recruitment and Duration: Around 45,000 to 50,000 soldiers (referred to as “Agniveers”) are recruited annually under this scheme. These recruits serve on a short-term contract of four years. After the initial four years, only 25% of the batch will continue for an additional 15 years under permanent commission. Benefits for Agniveers: Upon completing the four-year service, Agniveers receive a one-time “Seva Nidhi” package of Rs 11.71 lakhs, including accrued interest. They also enjoy a life insurance cover of Rs 48 lakhs during the service period. In case of death, the payout exceeds Rs 1 crore, including pay for the unserved tenure. The government assists in rehabilitating soldiers who leave the services after four years by providing skill certificates and bridge courses. Challenges and Concerns: Job Prospects: Agniveers may find it challenging to secure other jobs after their four-year service. No Pension Benefit: Unlike regular servicemen, Agniveers do not receive pension benefits.

Background:- India is still in the process of filing its nomination to IDSA.The Ladakh Union Territory administration is leading the efforts in establishing the country’s first Dark Sky Reserve. About Dark Sky Reserve A Dark Sky Reserve is public or private land with a distinguished nocturnal environment and starry nights that has been developed responsibly to prevent light pollution. According to the International Dark Sky Association (IDSA), these reserves “consist of a core area meeting minimum criteria for sky quality and natural darkness, and a peripheral area that supports dark sky preservation in the core.” How does a site become a ‘Dark Sky Reserve’? Individuals or groups can nominate a site for certification to the International Dark Sky Association (IDSA). There are five designated categories, namely International Dark Sky parks, communities, reserves, sanctuaries and Urban Night Sky Places. Between 2001 and January 2022, there have been 195 sites recognised as International Dark Sky Places globally, the IDSA said. The IDSA considers a piece of land suitable for dark sky place only if it is either publicly or privately owned; is accessible to the public partially or entirely during the year; the land is legally protected for scientific, natural, educational, cultural, heritage and/or public enjoyment purposes; the core area of the land provides an exceptional dark sky resource relative to the communities and cities that surround it and the land offers prescribed night sky brightness either for a reserve, park or sanctuary. Why was Ladakh chosen for the project? To be situated at a height of 4,500 metres above sea level, the Hanle Dark Sky Reserve (HDSR) will come up within the Changthang Wildlife Sanctuary. Ladakh is a unique cold desert located about 3,000 metres above sea level with high mountainous terrains. Long and harsh winters with minimum temperatures dropping to minus 40 degrees Celcius make large parts of the UT highly inhabitable. This aridity, limited vegetation, high elevation and large areas with sparse populations – all make it the perfect setting for long-term astronomical observatories and dark sky places. But the primary objective of the proposed Dark Sky Reserve is to promote astronomy tourism in a sustainable and environment-friendly manner. Scientific methods will be used here to preserve the night sky from ever-increasing light pollution.

Background: Karnataka Chief Minister said Bengaluru was facing a shortage of 500 million litres of water every day, which is about a fifth of the city’s daily total demand. Reasons behind water crisis: Monsoon : During last year’s monsoon, Karnataka received rainfall that was 18 per cent below normal.Even the post-monsoon period did not bring much rain to the state. Like most other parts of the country, Karnataka receives a bulk of its annual rainfall during the monsoon. A rainfall deficit in the monsoon months almost inevitably results in water stress. Another direct consequence of low rainfall has been the relatively low level of water in reservoirs. Latest data from the Central Water Commission shows that Karnataka reservoirs are currently holding water at only 26 per cent of their full capacity. Aquifers : South India has a very different kind of aquifer system. It is very rocky. The aquifers don’t hold a lot of water. They empty out quickly, and they also get recharged pretty quickly. What this means is that groundwater resources are not able to sustain for very long in the event of a prolonged dry spell. This is very different from the aquifers in north India, which have a much better capacity to hold water. This is why Bihar and Uttar Pradesh, which got even less rainfall last year than Karnataka, have not seen similar water scarcity.Aquifers in north India, once full, can hold enough water to sustain the demand for a couple of years. Dealing with Shortage Unregulated construction, systematic destruction of lakes, hindrances to the natural underground flow of water, and climate change, all affect the availability of water in Bengaluru.But these do not seem to be the immediate triggers for this particular ongoing shortage. This one has to do largely with the seasonal fluctuation in rainfall and the state’s inability to create capacities to deal with these kinds of variabilities. States need to develop capacities to deal with the disruptions through planning. The key is to put value on water. It is not a free resource. Low or optimum consumption needs to be incentivised while wastage must be discouraged.

Background:- In its pursuit to boost milk production through the crossbreeding of indigenous cattle with high-yielding foreign breeds, the White Revolution’s corollary was the erasure of breeds such as the Vechur cow. Cross-breeding served to dilute the genetic purity of native breeds and diminish their population. Vechur Cow The Vechur Cow is a rare breed named after the village Vechoor in Vaikom Taluk, Kottayam district of the state of Kerala in India. With an average length of 124 cm (about 4 feet and 1 inch) and height of 87 cm (about 2 feet and 10 inches), it is the smallest cattle breed in the world. The Vechur animals were saved from extinction due to conservation efforts by Sosamma Iype, a Professor of Animal breeding and Genetics along with a team of her students. Siri Cow Siri is a small sized draught purpose breed of hilly region of West Bengal and Sikkim. The animals can graze in the steep slope of hilly forest. The males are mainly reared for draught purpose in the hilly area and sometimes they are the only source of draught power. The breed produces very less amount of milk. Tharparkar Tharparkar is an important dual-purpose breed originating from the THAR desert of Rajasthan. The home tract of this breed is in the Tharparkar district of southeast Sindh in present day Pakistan. In India, these animals are now found along the Indo-Pak border covering western Rajasthan and up to the Rann of Kutch in Gujarat. The animals can thrive well on small bushy vegetation (Sewan grass) during drought and fodder scarcity condition and produce reasonabe amount of milk. Due to better heat tolerance and disease resistance, this breed was used for producing “Karan Fries” breed – a synthetic crossbred cattle breed at National Dairy Research institute (NDRI) The local breeds have following merits over exotic breeds Better disease resistance than exotic breeds. More suitable for low input management system. Survive better in local environment.

Background: In April 2023, Sebi barred five entities, including an employee of Life Insurance Corporation from the securities market and impounded illegal gains of Rs 2.44 crore made by them, in a case pertaining to front-running the trades of the state-owned insurer. About Front-running : Front-running means usage of non-public information to directly or indirectly, buy or sell securities or enter into options or futures contracts, in advance of a substantial order, on an impending transaction, in the same or related securities or futures or options contracts, in anticipation that when the information becomes public, the price of such securities or contracts may change. For example; a broker receives a request from a client to purchase 50,000 Company A shares. He keeps the order from the client until he executes an order for his personal account for the same stock. Then, when he places the customer’s request, share price increases due to the scale of the customer’s order.The rise creates the broker an immediate benefit. Front-running offers unfair profits to the entity who has confidential information that will affect the price of the asset. Front running is also known as tailgating.

Background: During this celestial event, the sun crosses the celestial equator, moving from the Southern Hemisphere to the Northern Hemisphere.   About EQUINOXES Equinoxes are astronomical events that occur twice a year when the Sun is exactly above the Equator, resulting in nearly equal lengths of day and night across the globe. The term “equinox” literally means “equal night”. The primary cause of equinoxes lies in the tilt of Earth’s axis. Earth orbits the Sun at an angle of approximately 23.5 degrees. As Earth revolves around the Sun, different parts of our planet receive varying amounts of solar radiation at different times of the year. Vernal Equinox: Vernal Equinox, also known as the Spring Equinox, marks the transition from winter to spring in the Northern Hemisphere. The Vernal Equinox typically occurs between March 19 and 21, depending on the specific year. In 2024, it falls on

Archives (PRELIMS & MAINS Focus)   E V Ramaswamy Naicker or Periyar Syllabus Prelims & Mains – History Context: Tamil Nadu Chief Minister M K Stalin has voiced his backing for Carnatic vocalist T M Krishna in the midst of a debate surrounding the conferral of the Sangita Kalanidhi title by the Music Academy, Madras. The matter has attracted political and societal interest, particularly regarding critiques of the social reformer Periyar. Background:- Over the years, Periyar has transcended the political divide as well as the faultlines of religion and caste, and come to be revered as Thanthai Periyar, the father figure of modern Tamil Nadu. About Periyar Born in 1879, Periyar is remembered for the Self Respect Movement aimed at achieving social equality for those oppressed by the caste system. Periyar started his political career as a Congress worker. He quarrelled with Gandhi over the question of separate dining for Brahmin and non-Brahmin students at Gurukkulam, a Congress-sponsored school owned by nationalist leader V V S Iyer in Cheranmahadevi near Tirunelveli. At the request of parents, Iyer had provided separate dining for Brahmin students, which Periyar opposed. Gandhi proposed a compromise, arguing that while it may not be a sin for a person not to dine with another, he would rather respect their scruples. After failing to bend the Congress to his view, Periyar resigned from the party in 1925, and associated himself with the Justice Party and the Self Respect Movement, which opposed the dominance of Brahmins in social life, especially the bureaucracy. The Justice Party had a decade earlier advocated reservation for non-Brahmins in the bureaucracy and, after coming to power in the Madras Presidency, issued an order to implement it. The Self Respect Movement he led promoted weddings without rituals, and sanctioned property as well as divorce rights for women. He appealed to people to give up the caste suffix in their names, and to not mention caste. He instituted inter-dining with food cooked by Dalits in public conferences in the 1930s. Periyar’s fame spread beyond the Tamil region during the Vaikom Satyagraha of 1924, a mass movement to demand that lower caste persons be given the right to use a public path in front of the famous Vaikom temple. Periyar took part in the agitation with his wife, and was arrested twice. He would later be referred to as Vaikom Veerar (Hero of Vaikom). He reconstructed the Tamil identity as an egalitarian ideal that was originally unpolluted by the caste system.He argued that caste was imported to the Tamil region. Under him, the Dravidian Movement became a struggle against caste and an assertion of Tamil national identity. In the 1940s, Periyar launched Dravidar Kazhagam, which espoused an independent Dravida Nadu comprising Tamil, Malayalam, Telugu, and Kannada speakers. For the average Tamil, Periyar today is an ideology. He stands for a politics that foregrounded social equality, self-respect, and linguistic pride. As a social reformer, he focused on social, cultural and gender inequalities, and his reform agenda questioned matters of faith, gender and tradition. He asked people to be rational in their life choices.

Background: The Gibraltar arc’s potential awakening could significantly impact the configuration of the Atlantic Ocean over millions of years. About GIBRALTAR ARC: The Gibraltar Arc, also known as the Gibraltar Subduction Zone, is a geological formation located beneath the Gibraltar Strait. The Strait of Gibraltar is a narrow passage connecting the Atlantic Ocean to the Mediterranean Sea. It serves as a natural boundary between Europe and Africa. This region marks the meeting point of two tectonic plates: the Eurasian Plate and the African Plate. The African Plate is currently subducting beneath the Eurasian Plate in this area. Subduction occurs when one tectonic plate slides beneath another, leading to seismic activity, volcanic eruptions, and the formation of mountain ranges. The Gibraltar Arc represents a dynamic boundary where these immense forces shape the Earth’s crust. Other Subduction Zones in Atlantic region is Lesser Antilles Arc in the Caribbean and Scotia Arc near Antarctica.

Key findings of the report: Inequality declined post-independence till the early 1980s, after which it began rising and has skyrocketed since the early 2000s. Between 2014-15 and 2022-23, the rise of top-end inequality has been particularly pronounced in terms of wealth concentration. By 2022-23, top 1 per cent income and wealth shares (22.6 per cent and 40.1 per cent) are at their highest historical levels and India’s top 1 per cent income share is among the very highest in the world, higher than even South Africa, Brazil and US. Wealth is highly concentrated even within the top 1 per cent. In 2022-23, the top 1 per cent wealth share was 39.5 per cent, 29 percentage points went just to the top 0.1 per cent, 22 percentage points to just the top 0.01 per cent and 16 percentage points to just the top 0.001 per cent. The sharp rise in top 10 per cent shares from 1991 onwards came at the loss of both bottom 50 per cent and middle 40 per cent shares. From stagnating at 11 per cent during 1961-1981,

Archives (PRELIMS & MAINS Focus)   Black Carbon Syllabus Prelims and Mains – Environment Context: At the COP26 climate talks in Glasgow in November 2021, India pledged to achieve net-zero emissions by 2070, positioning itself as a frontrunner in the race to carbon neutrality.While carbon dioxide mitigation strategies will yield benefits in the long term, they need to go hand-in-hand with efforts that provide short-term relief. Background:- Prioritising black carbon reduction through initiatives such as the PMUY scheme can help India become a global leader in addressing regional health concerns and help meet its Sustainability Development Goal of providing affordable clean energy to everyone and contributing to global climate mitigation. About Black Carbon Black carbon is the dark, sooty material emitted alongside other pollutants when biomass and fossil fuels are not fully combusted. It contributes to global warming and poses severe risks. Studies have found a direct link between exposure to black carbon and a higher risk of heart disease, birth complications, and premature death. Most black carbon emissions in India arise from burning biomass, such as cow dung or straw, in traditional cookstoves. According to a 2016 study, the residential sector contributes 47% of India’s total black carbon emissions. Industries contribute a further 22%, diesel vehicles 17%, open burning 12%, and other sources 2%. Decarbonisation efforts in the industry and transport sectors in the past decade have yielded reductions in black carbon emissions, but the residential sector remains a challenge. Role of Govt: In May 2016, the Government of India said the Pradhan Mantri Ujjwala Yojana (PMUY) would provide free liquefied petroleum gas (LPG) connections to households below the poverty line. The primary objective was to make clean cooking fuel available to rural and poor households and reduce their dependence on traditional cooking fuels. The PMUY has established infrastructure to go with LPG connections, including free gas stoves, deposits for LPG cylinders, and a distribution network. The programme has thus, been able to play a vital role in reducing black carbon emissions, as it offers a cleaner alternative to traditional fuel consumption. However, in 2022-2023, 25% of all PMUY beneficiaries — 2.69 crore people — availed either zero LPG refill or only one LPG refill, according to RTI data, meaning they still relied entirely on traditional biomass for cooking. Source:Hindu Sickle Cell Disease (SCD) Syllabus Prelims – Science Context: The U.S. Food and Drug Administration recently approved two gene therapies, Casgevy and Lyfgenia, to treat SCD in people ages 12 and older. Casgevy, developed by Vertex Pharmaceuticals and CRISPR Therapeutics and also approved in the U.K., is the first CRISPR-based therapy to have received regulatory approval in the U.S. Lyfgenia, manufactured by Bluebird Bio, doesn’t use CRISPR but depends on a viral vector to change blood stem-cells. Background: Genetic therapies have created a lot of hope for treating SCD, yet they require the same amenities still out of reach of those most affected by the disease. About Sickle Cell Disease (SCD) SCD is an inherited haemoglobin disorder in which red blood cells (RBCs) become crescent- or sickle-shaped due to a genetic mutation. These RBCs are rigid and impair circulation, often leading to anaemia, organ damage, severe and episodic pain, and premature death. India has the third highest number of SCD births, after Nigeria and the Democratic Republic of the Congo. Access to treatment as a major issue In 2023, the Government of India launched the National Sickle Cell Anaemia Elimination Mission, to eliminate SCD by 2047. At present, however, treatment and care for SCD remains grossly inadequate and inaccessible. Example is the unavailability of the drug hydroxyurea. It lessens the severity of pain, reduces hospitalisations, and improves survival rates by increasing the size and flexibility of RBCs and lowering their likelihood of becoming sickle-shaped. Blood transfusion is another important therapy for SCD, but its availability is limited to district-level facilities. Most block-level community health centres don’t offer them. Bone marrow transplantation (BMT), is out of reach for most SCD patients due to the difficulty in finding matched donors, the high cost of the treatment at private facilities, and long waiting times in public hospitals. In light of this, the application of the gene-editing technology called CRISPR (short for ‘Clustered Regularly Interspaced Short Palindromic Repeats’) to treat SCD is important – for its novelty and promise but also for the health disparities it makes apparent. India has approved a five-year project to develop CRISPR for sickle cell anaemia. Under its Sickle Cell Anaemia Mission, the Council of Scientific and Industrial Research is developing gene-editing therapies for SCD. Around Rs 34 crore has been allocated for this mission over 2020-2023. Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) It is originally a feature of the bacterial immune system.It forms the basis for this technology. In a nutshell, the system in bacteria serves as a warehouse for past infections by storing a part of the viral genetic material and incorporating it into its own, so the next time it is attacked, the bacteria is capable of recognising the virus and destroying it.The bacteria, in short, is immunised when it employs the CRISPR system. Researchers have adapted it as a tool to cut, delete, or add DNA sequences at precise locations, opening different windows to treat genetic disorders, develop drought-resistant plants, modify food crops, or experiment with de-extinction projects involving the woolly mammoth and the dodo.
