  • Total Allowable Catch (TAC) in Fishing

    Why in the News?

    A recent legal dispute between the US and Russia has brought the issue of Total Allowable Catch (TAC) into the spotlight.

    About Total Allowable Catch (TAC):

    • TAC refers to the maximum quantity of a specific fish species that can be legally harvested in a defined period.
    • It is established to prevent overfishing and ensure sustainable fish populations.
    • These limits are essential for maintaining ecological balance and supporting long-term fishing industries.

    Various Laws Governing TAC:

    • TACs are set by international fisheries management organizations like:
      • FAO (Food and Agriculture Organization).
      • RFMOs (Regional Fisheries Management Organizations) for shared or migratory fish stocks.
    • European Union (EU): TACs are managed under the Common Fisheries Policy (CFP), which sets quotas for member states based on scientific advice. Landing obligations ensure that all catches are counted against quotas, preventing waste.
    • India: India enforces a seasonal fishing ban in its Exclusive Economic Zone (EEZ) for 61 days to protect breeding fish. This ban serves as a TAC equivalent of zero for specific periods, supporting fish stock regeneration.
    • New Zealand: The Fisheries Act sets TACs for various stocks and specifies catch limits in terms of weight or numbers, updated by official notices.
    [UPSC 2013] The most important fishing grounds of the world are found in the regions where:

    Options: (a) Warm and cold atmospheric currents meet (b) Rivers drain out large amounts of freshwater into the sea (c) Warm and cold oceanic currents meet* (d) continental shelf is undulating.

     

  • Hydrogen versus Battery: The Cost of Clean Public Transport

    Why in the News?

    In India, a study published in The Lancet found that between 2008 and 2019, breathing in high levels of PM2.5 air pollution for short periods caused around 30,000 deaths each year in 10 major cities—making up about 7.2% of all deaths in those areas.

    What are the major health impacts of urbanisation-related air pollution in Indian cities, as reported by the Lancet study?

    • High Mortality Due to PM2.5 Exposure: Short-term exposure to fine particulate matter (PM2.5) caused nearly 30,000 deaths annually across 10 major Indian cities from 2008 to 2019.
    • Significant Share of Urban Deaths: These pollution-related deaths represented about 7.2% of all deaths in these cities, indicating a severe public health burden directly linked to air quality.
    • City-Specific Impact – Mumbai: Mumbai recorded the highest number of annual deaths due to PM2.5, with approximately 5,100 deaths each year attributed to air pollution.
    • Severe Effects in Eastern and Southern Metropolises: Kolkata and Chennai also showed worrying trends, with 4,678 deaths/year in Kolkata and 2,870 deaths/year in Chennai due to polluted air.
    • Urbanisation Intensifies Health Risks: Rapid urban growth increases traffic congestion and emissions, compounding the effects of air pollution and increasing the risk of respiratory and cardiovascular diseases.

    Why are Fuel Cell Electric Vehicles (FCEVs) considered more suitable for long-distance travel and extreme conditions despite their low adoption?

    • Longer Driving Range: FCEVs offer greater range than battery electric vehicles (BEVs) due to the higher energy density of hydrogen fuel. Eg: Hydrogen-powered vehicles can travel 500–700 km on a single tank, ideal for intercity transport.
    • Quick Refuelling Time: FCEVs can be refuelled in just 5–15 minutes, similar to petrol or diesel vehicles, unlike BEVs which may take hours to recharge. Eg: Hydrogen buses can be quickly refuelled during breaks, making them suitable for continuous long-haul operations.
    • Better Performance in Cold Weather: FCEVs are less affected by cold temperatures, which often reduce the efficiency and range of battery-powered vehicles. Eg: FCEVs are more reliable in regions with harsh winters like high-altitude or Himalayan areas.
    • Lighter Vehicle Weight: Hydrogen fuel cells are generally lighter than large lithium-ion battery packs, improving efficiency and payload capacity. Eg: Fuel cell trucks can carry more cargo weight over rugged terrain compared to heavier BEVs.
    • Ideal for Heavy-Duty and Rugged Use: Due to their durability and efficiency, FCEVs are well-suited for buses, trucks, and long-range vehicles on varied terrains. Eg: Countries like Japan and South Korea are deploying hydrogen buses for public transport in hilly and industrial regions.

    Which countries and regions are leading in global electric car sales and how does India compare?

    Country/Region 2023 EV Sales Market Share Key Highlights
    China 9.05 million 37% of total car sales World’s largest EV market; accounts for ~58% of global EV consumption
    Europe 3.02 million 24% of total car sales Strong adoption in countries like Norway, Germany, and the Netherlands
    United States 1.39 million 9.5% of total car sales Third-largest EV market globally
    India 80,000 ~5% of total car sales Rapid growth; EV sales nearly doubled in 2023; leading in electric three-wheeler sales

    When will hydrogen vehicle costs match battery-electric vehicles?

    • Cost Convergence Expected by 2030: Experts predict that the initial purchase cost of hydrogen Fuel Cell Electric Vehicles (FCEVs) will match that of BEVs by around 2030, due to advancements in hydrogen fuel cell technology and mass production. Eg: A hydrogen-powered bus may cost the same as a battery-electric bus by 2030, narrowing today’s 20–30% cost gap.
    • Technology and Manufacturing Scale-Up: As production scales up, the cost of fuel cells, hydrogen storage systems, and related components is expected to fall significantly. Eg: Mass production of hydrogen tanks and cheaper catalysts could lower vehicle costs similar to how lithium-ion battery costs declined over time.
    • Infrastructure Development and Government Support: Increased investment in hydrogen refuelling infrastructure and government subsidies are crucial for cost parity. Eg: Japan and South Korea are funding hydrogen highways and offering tax incentives to make hydrogen cars more affordable.
    • Operational Costs to Remain High: While initial costs may match BEVs by 2030, running costs are expected to remain significantly higher beyond that due to fuel prices. Eg: Operating a green hydrogen bus currently costs around $0.91/km, compared to $0.17/km for electric buses.
    • Limited Market Segments for Parity: Cost matching is likely only in specific segments like heavy-duty transport, not across all vehicle categories. Eg: Long-haul hydrogen trucks may achieve cost parity with electric trucks sooner than passenger cars due to their high utility.

    What are the steps taken by the Indian Government? 

    • FAME India Scheme: Launched in 2015, it offers financial incentives for EV adoption and charging infrastructure development. Phase II (2019) focuses on public transport EVs and charging stations.
    • PLI Scheme: A ₹26,000 crore initiative to boost domestic EV and hydrogen vehicle manufacturing, reduce imports, create jobs, and support ‘Make in India.’
    • Customs Duty Reduction: Import duties on EVs above $35,000 have been reduced from up to 100% to 15%, with a cap of 8,000 vehicles annually for five years, provided manufacturers commit to local production.
    • NEMMP: The 2013 National Electric Mobility Mission Plan aims to boost EV and hybrid vehicle adoption through technology, infrastructure, and demand generation.
    • State-Level Initiatives: States like Uttar Pradesh, Tamil Nadu, and Delhi have implemented various EV policies, including subsidies, tax waivers, and electric auto rickshaw programs to promote adoption.

    Way forward: 

    • Enhance R&D and Subsidies: Support innovation and provide financial incentives to reduce the cost of hydrogen vehicles and fuel.
    • Build Targeted Infrastructure: Develop hydrogen refuelling stations along key freight corridors and urban hubs.

  • Microplastics disrupting the Ocean’s Carbon Cycle

    Why in the News?

    A study published in Nature reveals that microplastics have deeply infiltrated the ocean, affecting the planet’s biogeochemical and carbon cycles.

    Microplastics

    Key Findings of the Study:

    • Microplastics (1–100 micrometres) dominate the ocean’s water column, especially below surface layers, unlike larger plastic fragments (100–5,000 micrometres) which remain near the surface.
    • Subsurface microplastics were found as deep as 100 metres within ocean gyres—rotating currents that trap and accumulate debris.
    • Data was compiled from 1,885 ocean stations (2014–2024), focusing on 50 cm below surface (subsurface layer).
    • Over 56 polymer types were detected; buoyant polymers, common in global plastic production, were most prevalent.
    • Sources identified:
      • Fishing gear, including nylon and polyester nets, was a significant contributor to deep-sea microplastics.
      • Plastics sampled often had production dates from the 20th century, highlighting their long degradation timelines.
      • Atmospheric deposition contributes 0.013–25 million tonnes annually, with polyester dominant in airborne microplastics.

    About Allochthonous Carbon:

    • Allochthonous carbon is carbon from external sources introduced into an ecosystem, not produced within it.
    • In oceans, plastics are a major source of allochthonous carbon, as they come from land-based human activities.
    • Microplastics contribute measurable carbon mass to marine systems, altering natural carbon ratios in ocean layers.
    • This distorts the marine carbon pump by affecting the flow and composition of particulate organic carbon (POC).
    • Impacts:

  • [5th May 2025] The Hindu Op-ed: Shaping the port of the future

    PYQ Relevance:

    [UPSC 2021] Investment in infrastructure is essential for more rapid and inclusive economic growth.” Discuss in the light of India’s experience.

    Linkage: Vizhinjam Port is seen as a major infrastructure project that can bring big economic benefits and boost growth in the region. This “port of the future” is a clear example of how building key infrastructure can help speed up development and strengthen India’s role in global sea trade.

     

    Mentor’s Comment:  The town of Vizhinjam in Kerala has been an important part of global sea trade since ancient times. Inscriptions from the Pandya-Chola period (1129 AD) refer to it as Rajendra Chola Pattinam, a key port in Kerala. Some historians believe that Vizhinjam was earlier known as Balita, a port mentioned in the 1st-century travel book The Periplus of the Erythraean Sea. Over time, however, Vizhinjam lost its importance when colonial powers began to focus on developing other ports like Cochin and Madras.

    Today’s editorial analyses the first deep-water container transhipment port at Vizhinjam. This content would help in the GS Paper II (International Relations) and GS Paper III (Port & Infrastructure).

    _

    Let’s learn!

    Why in the News?

    India’s first deep-water container transshipment port at Vizhinjam has been officially opened by the Prime Minister.

    What historical records highlight Vizhinjam’s ancient maritime significance?

    • Inscriptions from the Pandya-Chola Era (1129 AD): Vizhinjam was referred to as Rajendra Chola Pattinam, highlighting its importance under Chola rule. Eg: Inscriptions found in Tamil Nadu indicate Vizhinjam was a maritime outpost under Rajendra Chola I.
    • Mention in The Periplus of the Erythraean Sea (1st century AD): Scholars correlate Vizhinjam with Balita, a port listed in this Greco-Roman navigational text. Eg: The Periplus details trade with South Indian ports exporting spices, pearls, and textiles.
    • Vital Node in the Ancient Spice Route: Vizhinjam facilitated trade in pepper and aromatics between India and the Greco-Roman world. Eg: Goods from Kerala were shipped to Alexandria and further into Europe via this port.
    • Geographic Advantage as a Natural Port: Vizhinjam’s deep-sea location and sheltering coastline made it ideal for anchorage and monsoon navigation. Eg: Sailors preferred Vizhinjam for docking during the southwest monsoon season.
    • Decline Due to Colonial Maritime Reorientation: Colonial interests bypassed Vizhinjam in favor of Cochin and Madras, leading to its historical obscurity. Eg: The British East India Company developed Cochin, reducing Vizhinjam’s strategic relevance.

    Why is Vizhinjam Port crucial for India’s transshipment strategy?

    Why in the News?

    India’s Agriculture Minister has introduced ‘Kamala’ and ‘Pusa DST Rice 1’, the country’s first genome-edited rice varieties, developed by ICAR. These are also the world’s first genome-edited rice varieties.

    About ‘Kamala’ and ‘Pusa DST Rice 1’:

    • Kamala (DRR Dhan 100): Developed by ICAR-IIRR Hyderabad, derived from Samba Mahsuri; shows higher yield, early maturity, drought tolerance.
    • Pusa DST Rice 1: Developed by ICAR-IARI Delhi, based on MTU1010; improves drought and salinity tolerance.
    • Agencies involved: Indian Council of Agricultural Research (ICAR), ICAR-IIRR, ICAR-IARI.
    • They were created using CRISPR-Cas9-based genome editing, specifically Site Directed Nuclease 1 (SDN1). It has NO foreign DNA inserted.
    • It has been approved by Institutional Biosafety Committees (IBC) and Review Committee on Genetic Manipulation (RCGM) under relaxed genome-edit rules.

    Specific Benefits Offered:

    • Yield boost:
      • Kamala: +19% over Samba Mahsuri (avg. 5.37 t/ha, max. up to 9 t/ha).
      • Pusa DST Rice 1: +9.6% to +30.4% over MTU1010 under stress conditions.
    • Climate resilience:
      • Kamala: Drought tolerance, early maturity.

  • Repairability Index (RI) for Mobile and Electronics Sector

    Why in the News?

    The Committee formed to design India’s Repairability Index (RI) framework has submitted its report to Department of Consumer Affairs.

    About Repairability Index (RI):

    • The RI is a standardized label that indicates how easily a product can be repaired by assessing multiple parameters.
    • It is designed to empower consumers to make informed decisions and promote sustainable consumption.
    • The RI is applicable initially to smartphones and tablets and uses a 5-point numeric scale for scoring.
    • The six key parameters used to calculate RI are:
      1. Disassembly Depth
      2. Repair Information
      3. Spare Parts Availability
      4. Software Updates
      5. Tools Required
      6. Fasteners Used
    • The scoring covers priority components such as battery, display, cameras, charging port, microphone, speaker, and hinge mechanism.
    • RI labels must be displayed at the point of sale, on e-commerce platforms, and via QR code on packaging.

    Recommendations of the RI Framework:

    • The RI framework must align with global best practices while maintaining ease of doing business for manufacturers.
    • Original Equipment Manufacturers (OEMs) will self-declare RI scores based on standard criteria, with no extra compliance burden.
    • A clear scoring methodology has been developed, with weightages assigned to each parameter for key parts.
    • The committee identified smartphones and tablets as the initial focus under the RI framework.
    • Stakeholder consultations included manufacturers, consumer groups, academic bodies, and government departments.
    • The framework complements the existing Right to Repair Portal (launched in 2022), which provides repair-related information across four sectors.
    • The committee emphasized the need for a robust post-sale ecosystem for both urban and rural consumers.
