    export

    Central idea: The article discusses the top exporting districts in India and their contribution to the country’s overall exports. It also provides information on the top exported commodities in each district.

    Top Exporting Districts in India

    Rank District State Share of India’s Exports
    1 Jamnagar Gujarat 24%
    2 Surat Gujarat 4.5%
    3 Mumbai Suburban Maharashtra 4.5%
    4 Dakshina Kannada Karnataka –
    5 Devbhumi Dwarka, Bharuch, Kachchh Gujarat –
    6 Mumbai Maharashtra –
    7 Kancheepuram Tamil Nadu –
    8 Gautam Buddha Nagar Uttar Pradesh –

     

    Top Exporting Districts in Each State

    • Map 1 shows the district that formed the highest share of a State’s exports in FY23.
    • The size of the circle in the map corresponds to the value of exports.
    • Most top exporting districts in the north-eastern States formed as much as 90% of a State’s exports, while some top exporting districts formed only around 20% of a State’s exports.

    Top Exported Commodities

    • Jamnagar’s dominance can be attributed to the fact that it formed a lion’s share of India’s surging petroleum exports, while Kancheepuram’s most exported commodity was smartphones.
    • Map 1 also lists the top exported commodity of the top exporting districts in each State.

    Top Exporting Districts for Each Commodity

    • Maps 2A-2F show the top five exporting districts for the top six commodities exported by India.
    • They include petroleum products, precious stones and jewellery, rice, wheat and other cereals, smartphones and electronic parts, vehicles other than railways, and pharmaceutical products.

    Share of Top Exporting Commodity

    • Table 3 shows the share of the top exporting commodity of the top exporting district in India’s total exports.
    • For instance, Jamnagar’s petroleum products export formed 67% of India’s total exports for that commodity, while Surat’s precious stones and jewellery exports formed 36% of India’s total exports for that commodity.

     

  • WTO panel rules against India in IT tariffs dispute

     

    A World Trade Organization (WTO) panel has ruled that India has violated global trading rules in a dispute with the European Union (EU), Japan, and Taiwan over import duties on IT products.

    About World Trade Organization (WTO)

    Details
    Purpose Regulate and facilitate international trade between nations
    Establishment 1995
    Headquarters Geneva, Switzerland
    Membership 164 member countries as of 2023, representing over 98% of global trade
    Goal Promote free and fair trade by negotiating and enforcing rules and agreements governing international trade
    Agreements Administers a number of agreements, including GATT, SPS Agreement, and TRIPS Agreement
    Dispute Resolution Operates a dispute settlement system to resolve conflicts between member countries
    Technical Assistance Provides technical assistance and training to help developing countries participate more effectively in international trade
    Decision-Making Body Ministerial Conference, which meets every two years
    Director-General Chief executive responsible for overseeing the organization’s operations and activities
    Criticisms Some criticize the WTO for being undemocratic, favoring developed countries, and not doing enough to promote labor and environmental standards in international trade

     

    What was the case?

    • The case involved a dispute over India’s introduction of import duties ranging from 7.5% to 20% on a wide range of IT products, including mobile phones, components, and integrated circuits.
    • The EU, Japan, and Taiwan challenged these import duties in 2019, arguing that they exceeded the maximum rate allowed under global trading rules.
    • The recent ruling by the WTO panel found that India had violated these rules and recommended that India bring its measures into conformity with its obligations.

    WTO Panel’s Ruling

    • The WTO panel has ruled that India violated global trading rules by imposing these import duties.
    • The panel recommended that India bring these measures into conformity with its obligations.
    • While the panel broadly backed the complaints against India, it rejected one of Japan’s claims that India’s customs notification lacked “predictability”.

    Implications of the ruling

    • The EU is India’s third-largest trading partner, accounting for 10.8% of total Indian trade in 2021, according to the European Commission.
    • The ruling could have implications for trade relations between India and the EU, as well as Japan and Taiwan.
    • India may be required to lower or eliminate the challenged import duties.
    • It remains to be seen whether India will appeal against the ruling.
    • If it does, the case will sit in legal purgatory since the WTO’s top appeals bench is no longer functioning due to US opposition to judge appointments.

    Conclusion

    • The panel recommended that India bring such measures into conformity with its obligations, and it remains to be seen whether India will appeal against the ruling.
    • The case highlights the importance of complying with global trading rules and the role of the WTO in resolving trade disputes between countries.

     

  • What is Great Pacific Garbage Patch?

    pacific

    Central idea: The article reports on a recent study which found evidence that coastal life forms have colonized plastic items in the Great Pacific Garbage Patch, a vast area in the North Pacific Ocean where plastic waste has accumulated due to ocean currents.

    What is the Great Pacific Garbage Patch (GPGP)?

    Features
    Location North Pacific Subtropical Gyre (NPSG), north of the equator in the Pacific Ocean
    Currents Kuroshio, North Pacific, California, and North Equatorial currents, moving in a clockwise direction
    Sources Any trash that enters one of these currents from any of the 51 Pacific Rim countries
    Size Estimated to be 1.6 million sq. km
    Age More than 50 years old
    Plastic Content Estimated to contain 45,000-129,000 metric tonnes of plastic, predominantly in the form of microplastics
    Visible Objects Heavier, more visible objects that haven’t yet broken down into smaller particles accounted for 92% in 2018

     

    Findings of the new study

    • Researchers from Canada, the Netherlands, and the U.S. have reported that coastal life forms have colonized plastic items in the Great Pacific Garbage Patch.
    • From November 2018 to January 2019, they collected 105 pieces of plastic debris, the most heavily plastic-polluted ocean gyre on the globe.
    • Based on studying them, they reported that 98% of the debris items had invertebrate organisms.

    Plastic inflicting into a coastal organism

    • Organisms found on coasts were getting by on small floating islands of garbage out in the Pacific Ocean, which the researchers named the neopelagic community.
    • They found organisms belonging to 46 taxa, and 37 of them were coastal; the rest were pelagic. Among both coastal and pelagic organisms, crustaceans were the most common.
    • Nearly all taxa were of Northwest Pacific origin, including Japan.
    • Eight of the remainder were from East Asia and five specifically from Japan. Four items were from North America.
    • They found that 68% of the coastal taxa and 33% of the pelagic taxa reproduced asexually and that there was evidence of sexual reproduction among the hydroids and the crustaceans, among others.

    Implications of the findings

    • Marine plastic pollution has given rise to a new kind of standing coastal community in the open ocean.
    • The neopelagic community is not misplaced but lives on plastic items in the garbage patch, including reproducing there.
    • The finding recalls other studies that show the chemical bonding of plastic with rocks, sedimentary rocks embedded with plastic earrings in Brazil, and the formation of plastiglomerates in Hawaii.

     

    What is neopelagic community?

    • The neopelagic community refers to the group of organisms that inhabit the open ocean or the pelagic zone beyond the continental shelf.
    • It is characterized by deep waters with very few physical structures or substrate for organisms to attach to.
    • This community includes a wide variety of organisms, including zooplankton, fish, squid, and marine mammals, among others.
    • These organisms have adapted to survive in the open ocean environment, which can be quite challenging due to factors such as temperature fluctuations, limited food availability, and the absence of physical structures for shelter.
    • The neopelagic community is an important part of the global marine ecosystem, playing a key role in nutrient cycling and energy transfer between different levels of the food chain.

     

    GPGP and its impact on marine life

    • The GPGP has significant impacts on marine life due to the ingestion of plastic by marine animals, which can cause harm and even death.
    • Plastic can also entangle and suffocate marine animals, leading to the disruption of ecosystems.
    • The new study sheds light on the neopelagic community, which has adapted to living on plastic in the garbage patch.

    Plastic pollution and its environmental impact

    • Plastic pollution is a major environmental issue that affects land and water ecosystems worldwide.
    • Plastic waste can take hundreds of years to decompose, and even then, it breaks down into microplastics that can persist in the environment indefinitely.
    • The presence of plastic in the environment has negative impacts on biodiversity, ecosystem function, and human health.

    Conclusion

    • There are various solutions to plastic pollution, including reducing the use of single-use plastics, recycling, and promoting alternative materials.
    • Governments and industries can also take steps to reduce plastic waste, such as implementing policies and regulations that reduce plastic use and increase recycling.
    • Individual actions, such as reducing personal plastic consumption and properly disposing of plastic waste, can also make a difference.

     

  • What is Polar Crown Prominence (PCP)?

    crown

    Central idea: The article talks about an astrophotographer named Andrew McCarthy capturing an image of a plasma waterfall on the sun. The phenomenon is called Polar Crown Prominence (PCP).

    Polar Crown Prominence (PCP)

    • PCP is a solar phenomenon that occurs on the sun’s Polar Regions.
    • It is a type of solar prominence, which is a large, bright, gaseous feature that extends out from the sun’s surface.
    • A solar prominence is a large, bright, gaseous feature that extends out from the sun’s surface.
    • It is made up of ionized gas (plasma) that is held in place by magnetic fields.
    • Prominences are visible during total solar eclipses and can also be observed using specialized telescopes.
    • PCPs are often associated with sunspots, which are dark regions on the sun’s surface that are caused by magnetic activity.

    How are PCPs Formed?

    • PCPs are formed by the interaction of magnetic fields on the sun’s surface.
    • Magnetic fields are created by the movement of charged particles (plasma) in the sun’s interior.
    • When these magnetic fields interact, they can create regions of intense magnetic activity, such as sunspots.
    • PCPs are often associated with these regions of magnetic activity.

    Why are PCPs Important?

    • PCPs are important because they provide clues about the sun’s magnetic activity and how it affects the Earth’s environment.
    • Solar activity, including PCPs, can cause disturbances in the Earth’s magnetic field, which can lead to auroras and disruptions in communication systems.

     

     

  • India’s first Mangrove Pitta Birds Census conducted in Odisha

    pitta

    Central idea: The article talks about the first-ever census of mangrove pitta birds conducted in two coastal districts of Odisha, India.

    About Mangrove Pitta

    • The mangrove pitta (Pitta megarhyncha) belongs to the family of pittas, the Pittidae.
    • The mangrove pitta species is distributed in India, Bangladesh, Myanmar, Thailand, Malaysia, Singapore and Indonesia.
    • These pitta species have fragmented distribution and considered ‘Near Threatened’ by IUCN. These pittas are monotypic species.

    Focus of the Census

    • In this census, a total of 179 individual mangrove pitta birds were counted.
    • The census mainly focused on the mangrove patches along the coasts of Kendrapara and Jagatsingpur districts.
    • Information was collected on the distribution, habitat, and breeding of mangrove pittas along the coastal mangroves.
    • The census was carried out by point count method, either by walking in the forest or using country boats in the creeks.

     

  • Constitution Bench formed in Same-Sex Marriage Case

    bench

    The Supreme Court has announced the formation of a new Constitution Bench headed by Chief Justice of India DY Chandrachud to hear a series of petitions seeking legal recognition of same sex marriages.

    What is a Constitution Bench?

    • The constitution bench is the name given to the benches of the Supreme Court of India.
    • The Chief Justice of India has the power to constitute a Constitution Bench and refer cases to it.

    Constitution benches are set up when the following circumstances exist:

    1. Interpretation of the Constitution: Article 145(3) provides for the constitution of at least five judges of the court which sit to decide any case “involving a substantial question of law as to the interpretation” of the Constitution of India.
    2. President of India seeking SC’s opinion: When the President has sought the Supreme Court’s opinion on a question of fact or law under Article 143 of the Constitution. Article 143 of the Constitution provides for Advisory jurisdiction to the SC. As per the provision, the President has the power to address questions to the apex Court, which he deems important for public welfare.
    3. Conflicting Judgments: When two or more three-judge benches of the Supreme Court have delivered conflicting judgments on the same point of law, necessitating a definite understanding and interpretation of the law by a larger bench.
    • The Constitution benches are set up on ad hoc basis as and when the above-mentioned conditions exist.
    • Constitution benches have decided many of India’s best-known and most important Supreme Court cases, such as:
    1. K. Gopalan v. State of Madras (Preventive detention)
    2. Kesavananda Bharati v. State of Kerala (Basic structure doctrine) and
    3. Ashoka Kumar Thakur v. Union of India (OBC reservations) etc.

    Why in news now?

    • The Centre had expressed its concern about the “psychological impact” that same-sex unions could have on children, but refused to link its worries to stigma about same-sex relationships.
    • The government’s recent affidavit sought to explain how same-sex marriage was antithetical to the view held by many in India that marriage was a “holy union, a sacrament and a sanskar” between a biological man and a woman.

     

  • Top-notch Aspirational Toilets to usher in change

    toilet

    The Ministry of Housing and Urban Affairs has issued a directive to all state governments to ensure that 25% of public toilet seats added in any city or urban unit are “aspirational toilets.”

    What are Aspirational Toilets?

    • The aspirational toilets scheme was launched in September 2022 as part of the Swachh Bharat Mission (SBM) 2.0, with an aim to help make cities open defecation free.
    • A quarter of all new public restrooms in Indian cities will soon have high-end features such as luxurious bath cubicles, touchless flushing, breast-feeding rooms, and automatic sanitary napkin incinerators.
    • These will be indicated as “aspirational toilets” on Google Maps.

    Focus areas for constructing aspirational toilets

    • The focus areas for constructing these luxury toilets will be tourist and religious destinations, as well as iconic cities.
    • High-footfall locations such as markets, railway stations, inter-state bus depots, and national highways will be given priority.
    • Guidelines have been issued to the states for constructing these toilets. It also includes low-height toilets and basins for children.
    • Hand-dryers, paper napkins, and vending machines for sanitary napkins are proposed to be made available.

    Maintenance and funding patterns

    • One of the business models being explored for the maintenance of these toilets is attaching them with other public services such as restaurants, shopping malls, libraries, cinema halls, or even medicine shops, to make them self-sustaining.
    • Experts have cautioned that a proper study must be done on the location and the way these toilets will be maintained before beginning any such project.

  • Omicron evolved strategies to evade T Cell Immunity

    t cell

    Central idea: The SARS-CoV-2 virus has the ability to evade CD8 T cells, which are important in reducing the viral load and clearing the infection by detecting and killing infected cells.

    What is the news?

    • A recent study has revealed that the SARS-CoV-2 virus has the ability to modulate MHC I expression in host cells.
    • MHC I is crucial in alerting the immune system to virally infected cells.
    • The virus has evolved multiple strategies to inhibit MHC I expression, which is not seen in the case of the influenza virus.

    What is T Cell Immunity?

    • Like B cells, which produce antibodies, T cells are central players in the immune response to viral infection.
    • For your immune system to fight off any kind of invader, such as a virus, you need a kind of white blood cell called a B cell, which makes antibodies, and a similar-looking white blood cell called a T cell.
    • T cells can play different roles altogether.
    • They can act as “killer cells”, attacking cells which have been infected with a virus or another kind of pathogen, or they can act as “helper cells” by supporting B cells to produce antibodies.

    How do they function?

    • Alongside antibodies, the immune system produces a battalion of T cells that can target viruses.
    • Some of these, known as killer T cells (or CD8+T cells), seek out and destroy cells that are infected with the virus.
    • Others, called helper T cells (or CD4+T cells) are important for various immune functions, including stimulating the production of antibodies and killer T cells.
    • T cells do not prevent infection, because they kick into action only after a virus has infiltrated the body. But they are important for clearing an infection that has already started.
    • In the case of COVID-19, killer T cells could mean the difference between a mild infection and a severe one that requires hospital treatment.

     

     

  • In news: Pralay Ballistic Missile

    pralay

    India is going to buy 250 more Pralay ballistic missiles for the services to strengthen them on the northern borders, further boosting the firepower of the defence forces.

    Pralay Ballistic Missile

    • Pralay is a tactical missile developed from India’s K-series of submarine-launched ballistic missiles (SLBMs).
    • It has a range of 150-500 km and can carry warheads weighing between 350 to 700 kg.
    • The missile is a canisters road-mobile system, which enhances its mobility and allows for quick preparation and launch of the missile.
    • Pralay has the ability to perform manoeuvres in flight and follows a quasi-ballistic trajectory to maintain high speed, making it difficult for enemy missile defence systems to intercept.

    Classification

    • The Indian Defence Ministry has classified Pralay as a “conventional Surface-to-Surface missile”.
    • This distinguishes it from the Agni series of missiles, which have the capability to carry either conventional or nuclear warheads.

    Testing and launch

    • The missile was launched on a quasi-ballistic trajectory in one of the two tests, which enhances its effectiveness against enemy missile defence systems.
    • Satellite imagery of the test shows that Pralay is a canisterised road-mobile system, which adds to its mobility and flexibility in responding to evolving threats.
