  • Wildlife Conservation Efforts

    Culling of Vermins

    Why in the News?

    The Kerala Cabinet is exploring the legal possibility of introducing a bill to permit scientific and regulated culling of wild animals, particularly feral boars.

    What are Vermins?

    • Definition: Vermins are animals considered harmful or nuisance-causing because they damage crops, threaten livestock, or pose risks to human life and property.
    • Examples: Common vermins include rats, mice, common crows, and fruit bats.
    • Legal Effect: When an animal is classified as vermin, it loses legal protection and becomes exempt from conservation safeguards.

    Provisions Related to Vermin in Wildlife Protection Act (WPA), 1972:

    • Schedule V: Lists animals classified as vermin, which can be hunted freely.
    • Section 62: Allows the central government to declare any wild animal (except those in Schedule I and Part II of Schedule II) as vermin for a specified area and time period.
    • Protection Status: Once declared vermin, the animal is treated as a Schedule V species, losing protection.
    • Exclusions: Animals in Schedules I and II (e.g., tigers, elephants) enjoy the highest protection and cannot be declared vermin.
    • Section 11: Chief Wildlife Wardens can allow trapping, capture, or killing of animals like wild boars in cases of public safety or property damage.
    • Wildlife Protection (Amendment) Act, 2022:
      • Reduction of Schedules: From six to four, with Schedule V has been removed.
      • Direct Declaration Power: It allows the Centre to directly declare any species (except those in Schedule I) as vermin, enabling broader culling without the older categorisation system.

    How are Vermins Declared?

    • State Initiation: The state sends a formal request to the Ministry of Environment, Forest and Climate Change (MoEFCC).
    • Declaration: If justified, the Centre issues a notification, declaring the species vermin for a specific region and time frame.
    • Temporary Status: This declaration is not permanent and applies only to the area and time mentioned.
    • Examples:
      • Wild boar in Uttarakhand
      • Nilgai (blue bull) in Bihar
      • Rhesus monkeys in Himachal Pradesh

    TR1 Cells: The Hidden Warriors in Malaria Immunity

    Why in the News?

    Scientists at Stanford University discovered that TR1 cells play a dominant role in fighting malaria reinfections.

    Understanding the Body’s Immune Response:

    • What is the Immune System? It’s the body’s defence system that protects us from infections like malaria.
    • First Defence: The skin and body surfaces block germs from entering.
    • Innate Immunity: If germs get in, the innate immune system reacts fast, like an emergency response team.
    • Adaptive Immunity: Then, the adaptive immune system kicks in, targeting germs specifically and remembering them for future protection.
    • B-Cells and T-Cells:
      • B-cells make antibodies to fight germs.
      • T-cells attack infected cells and guide other immune cells.
    • Helper T-Cells: A type called CD4+ T-cells helps organise the defence. Earlier, scientists thought TH1 cells were key in malaria, but a new study shows TR1 cells are more important, especially in repeat infections.

    What are TR1 Cells?

    • Role of TR1 Cells: These are special T-cells that help control the immune system and prevent overreaction.
    • Major Response in Malaria: Though small in number, during malaria, TR1 cells become the main helper cells.
    • Study in Uganda: In young children with repeated malaria, TR1 cells grew in number and improved the body’s ability to fight malaria without severe illness.
    • Memory and Immunity: TR1 cells remember the malaria parasite and return stronger with each infection.
    • Types of TR1 Cells:
      • Naïve TR1 – not yet active.
      • Effector TR1 – fighting infection.
      • Memory TR1 – remembering past infections.
    • Epigenetic Role: TR1 cells may respond by switching genes on or off, not by changing the genes themselves.

    Key Findings of the Study:

    • Research Team: Scientists from Stanford University studied people in Uganda over many months and years.
    • Tracking Infections: They followed individuals through multiple malaria infections to see how immune cells behaved.
    • Gene Scanning: A special technique was used to read the genes of each immune cell — like scanning a barcode.
    • Findings: TR1 cells were accurate, long-lasting, and clearly connected to malaria (not other infections).
    • Why it matters: This discovery can help in making better malaria vaccines, boosting long-term protection, and even improving treatments for other serious diseases.
    [UPSC 2025] With reference to monoclonal antibodies, consider the following:

    I. They are man-made proteins. II. They stimulate the patient’s immune system to fight the specific disease. III. They are produced using animal cells only.

  • Minimum Support Prices for Agricultural Produce

    Cabinet approves hike in MSP for Kharif Crops

    Why in the News?

    The Cabinet Committee on Economic Affairs chaired by Prime Minister has approved the increase in the Minimum Support Price (MSP) for 14 kharif crops for 2025-26.

    What is the Minimum Support Price (MSP)?

    • MSP in India originated in response to food shortages in the 1960s, notably during the Bihar famine of 1966–1967.
    • Agricultural Price Commission (APC) was established in 1965 to implement price policies like procurement at pre-decided prices and MSP.
    • Over time, the APC evolved into the Commission for Agricultural Costs and Prices (CACP) in 1985, with broader terms of reference.
    • Announcement: The government bases its announcement on the recommendations given by the Commission for Agricultural Costs & Prices (CACP).

    Steps involved in Fixing MSPs:

    • CACP sends its recommendations to the Government of India.
    • The reports are shared with state governments and concerned central ministries for comments.
    • After reviewing all inputs, the Cabinet Committee on Economic Affairs (CCEA) takes the final decision on MSPs.
    • Once approved, CACP publishes all its reports online, ensuring transparency and explaining the rationale behind its recommendations.

    How is MSP fixed?

    • Formulae for Calculation:
      • A2: Costs incurred by the farmer in production of a particular crop. It includes several inputs such as expenditure on seeds, fertilisers, pesticides, leased-in land, hired labour, machinery and fuel
      • A2+FL: Costs incurred by the farmer and the value of family labour
      • C2: A comprehensive cost, which is A2+FL cost plus imputed rental value of owned land plus interest on fixed capital, rent paid for leased-in land
    • National Commission of Farmers also known as the Swaminathan Commission (2004) recommended that the MSP should at least be 50 per cent more than the weighted average Cost of Production (CoP), which it refers to as the C2 cost.
    • The government maintains that the MSP was fixed at a level of at least 1.5 times of the all-India weighted average CoP, but it calculates this cost as 1.5 times of A2+FL.
    • Crops covered are: CACP currently recommends MSPs for 23 key crops:
      • 7 Cereals: Paddy, Wheat, Maize, Sorghum (Jowar), Pearl Millet (Bajra), Barley, and Ragi
      • 5 Pulses: Gram (Chana), Tur (Arhar), Moong, Urad, and Lentil (Masur)
      • 7 Oilseeds: Groundnut, Rapeseed-Mustard, Soybean, Sesame, Sunflower, Safflower, and Nigerseed
      • 4 Commercial Crops: Copra, Cotton, Raw Jute and Sugarcane (Fair and Remunerative Price (FRP) is announced by CACP.)
    [UPSC 2020] Consider the following statements:

    1. In the case of all cereals, pulses and oil-seeds, the procurement at Minimum Support Price (MSP) is unlimited in any State/UT of India.

    2. In the case of cereals and pulses, the MSP is fixed in any State/UT at a level to which the market price will never rise.

  • Judicial Appointments Conundrum Post-NJAC Verdict

    Supreme Court Collegium recommends transfer of HC CJs

    Why in the News?

    The Supreme Court Collegium has recommended the transfer of 4 Chief Justices from the High Courts of Madras, Rajasthan, Tripura, and Jharkhand.

    About the Collegium System:

    • Definition: It is used in India for the appointment and transfer of judges to the Supreme Court and High Courts.
    • Non-Constitutional Origin: It is not mentioned in the Constitution or any law passed by Parliament. It developed through Supreme Court judgments to protect judicial independence.
    • Judicial Primacy: The system ensures that senior judges, not the government, have the main say in judicial appointments.
    • Evolution: It arose in response to executive interference during the 1970s, when the government tried to influence and supersede senior judges:
    • First Judges Case (1981)S.P. Gupta v. Union of India:
      • Held that the Chief Justice’s opinion was only consultative.
      • Gave the executive primary control over appointments and transfers.
    • Second Judges Case (1993)Advocates-on-Record Association v. Union of India:
      • Overruled the First Judges Case.
      • Declared that “consultation” with the CJI means “concurrence”, making the CJI’s view binding.
      • Introduced the Collegium system, involving the CJI and two senior-most judges.
      • Affirmed that judicial independence requires judicial primacy in appointments.
    • Third Judges Case (1998)Re: Presidential Reference:
      • Expanded the Collegium to include the CJI and four senior-most Supreme Court judges.
      • Emphasised institutional decision-making, not personal preferences of individual judges.

    How does the Collegium System works?

    • For Supreme Court Judges:
      • The Collegium includes the CJI and four senior-most SC judges.
      • It recommends names for appointments to the SC and appointments/transfers of High Court judges and Chief Justices.
      • The Law Ministry processes these names and sends them to the Prime Minister, who advises the President for final approval.
    • For Appointing the Chief Justice of India:
      • The sitting CJI recommends the senior-most SC judge.
      • This practice has been followed since the 1970s supersession controversy.
    • For High Court Judges:
      • Recommendations start from the Chief Justice of the High Court, who consults two senior colleagues.
      • The proposal goes to the state government, then to the Supreme Court Collegium (CJI and two senior-most SC judges), and finally to the President.
    • For Transfers of Judges:
      • Article 222 of the Constitution allows transfer of High Court judges.
      • The Collegium recommends transfers, often for administrative needs or public interest.
      • Consent is not needed, but the CJI must consult the Chief Justice of the concerned High Court and other senior judges.
      • No High Court can have an Acting Chief Justice for more than a month, so transfers and new appointments are usually done together.

    [UPSC 2012] What is the provision to safeguard the autonomy of the Supreme Court of India?

    1. While appointing the Supreme Court Judges, the President of India has to consult the Chief Justice of India. 2. The Supreme Court Judges can be removed by the Chief Justice of India only. 3. The salaries of the Judges are charged on the Consolidated Fund of India to which the legislature does not have to vote. 4.

  • Monsoon Updates

    Bow Echo Storms

    Why in the News?

    New Delhi recently faced a severe thunderstorm with winds up to 100 kmph, forming a bow echo — a crescent-shaped pattern seen on weather radar.

    About Bow Echo:

    • What is it: A bow echo is a storm pattern on radar that looks like a curved bow, similar to an archer’s bow.
    • Storm Type: It forms inside a mesoscale convective system (MCS) — a large group of organised thunderstorms.
    • Origin of Term: The term was first used by Ted Fujita, who also created the Fujita scale for tornadoes.
    • How It Forms:
      • Heavy rain causes cool air to sink and spread out near the ground.
      • This cool air forms a gust front, which pushes warm, moist air upward, creating new storms.
      • A rear inflow jet — strong mid-level winds — pushes the storm forward, bending it into a bow shape.
      • Bookend vortices may form at both ends of the bow, and the northern end can sometimes generate tornadoes.

    Size, Impact, and Dangers:

    • Size and Duration: Bow echoes usually span 20 to 200 km and last 3 to 6 hours.
    • Wind Strength: They often produce straight-line winds over 100 km/h, like those seen in Delhi’s recent storm.
    • Derechos: In severe cases, bow echoes can grow into derechos, which are long-lasting and widespread windstorms.
    • Impacts:
      • Damaging Winds: Knock down trees, power lines, and damage buildings.
      • Brief Tornadoes: May form at the storm’s edges, especially at the northern end.
      • Microbursts and Downbursts: Intense short-lived wind blasts within the storm that cause local destruction.
    [UPSC 2013] During a thunderstorm, the thunder in the skies is produced by the-
