  • What is in Great Nicobar, site of NITI Aayog’s mega Island Project?

    Why in the News?

    • The opposition party has demanded the immediate suspension of all clearances granted to NITI Aayog’s Great Nicobar Island (GNI) Project.
    • It alleged violations of due process, legal and constitutional provisions protecting tribal communities.

    Great Nicobar Island: An Overview

    • Geography and Ecology: Southernmost tip of India, part of the Andaman and Nicobar archipelago comprising 600-odd islands.
    • Environment: Hilly, covered with lush rainforests, annual rainfall of around 3,500 mm.
    • Biodiversity: Hosts numerous endangered and endemic species including the giant leatherback turtle, Nicobar megapode, Great Nicobar crake, Nicobar crab-eating macaque, and Nicobar tree shrew.
    • Area: 910 sq km with mangroves and Pandan forests along the coast.
    • Indigenous Communities:
      • Shompen Tribe: Approximately 250 people live in interior forests, predominantly hunter-gatherers, classified as a Particularly Vulnerable Tribal Group.
      • Nicobarese Community: Two groups – Great Nicobarese and Little Nicobarese, practice farming and fishing.
      • Resettlement: The Great Nicobarese were resettled in Campbell Bay after the 2004 tsunami.
    • Administrative Hub: Campbell Bay serves as the administrative hub, housing local offices of the Andaman and Nicobar administration and the panchayat.

    Back2Basics: “Nicobar Triangle”

    It is named after the Nicobar Islands, which are located at the northern apex of this triangular area.

    The islands within the Nicobar Triangle include:

    1. Nicobar Islands: This group of islands belongs to India and is situated to the south of the Andaman Islands. They are known for their diverse flora and fauna and are inhabited by indigenous tribes.
    2. Andaman Islands: Located to the north of the Nicobar Islands, the Andaman Islands are also part of India. They are well-known for their lush forests, coral reefs, and indigenous tribes.
    3. Indonesian Archipelago: To the south and southeast of the Nicobar Islands lies the Indonesian archipelago, which includes thousands of islands spanning a vast area between the Indian and Pacific Oceans.

    What is GNI Project?

    The GNI Project refers to the “Holistic Development of Great Nicobar Island,” a proposed mega project being piloted by NITI Aayog.

    • Implementing Agency: The project is to be implemented by the Andaman and Nicobar Islands Integrated Development Corporation (ANIIDCO).
    • Historical Context: Development plans for a port in Great Nicobar date back to the 1970s, aimed at leveraging its strategic location near the Malacca Strait.
    • The project aims to develop the southern end of the Andaman and Nicobar group of Islands in the Bay of Bengal by constructing –
    1. Transshipment port
    2. Dual-use military-civil international airport
    3. Power plant (450 MVA gas and solar-based) and
    4. A township over a span of 30 years on more than 160 sq. km of land, of which 130 sq. km is primary forest

    Features of the Project

    • Transshipment hub of the East: The proposed port will allow Great Nicobar to participate in the regional and global maritime economy by becoming a major player in cargo transshipment.
    • Naval control: The port will be controlled by the Indian Navy, while the airport will have dual military-civilian functions and will cater to tourism as well.
    • Urban amenities: Roads, public transport, water supply and waste management facilities, and several hotels have been planned to cater to tourists.

    Significance of the project

    • Economic significance: The proposed port would allow GNI to become a significant player in cargo transhipment, as it is positioned equidistant from Colombo, Port Klang (Malaysia), and Singapore.
    • Strategic significance: The proposal to develop GNI has been on the table since the 1970s, and it has been highlighted repeatedly as a crucial element for national security and consolidation of the Indian Ocean Region.
      • In recent years, the escalating Chinese presence in the Indian Ocean has added greater urgency to this imperative.

    Issues with the Project

    • The project entails the deforestation of 130 sq km, and felling 10 lakh trees, threatens biodiversity at Galathea Bay, displaces indigenous tribes, lacks thorough impact assessments, and poses seismic risks to vulnerable communities.

    Due-process Violations highlighted by the ‘Opposition’

    (1) Did not recognise the grant ownership: The island administration did not recognise or grant ownership of any forest land to local tribespeople as per FRA, a requisite step under the Forest Conservation Rules, 2017, before Stage-I clearance is granted.

    • This is despite the fact that Rule 6(3)(e) of Forest Conservation Rules-2017 (FCR) requires that any diversion of forest land first requires the District Collector to recognise and vest rights to locals under the FRA.
    • The legislation allows forest communities the right to control and manage the use of the forest land over which they hold titles, and their consent is mandatory for diverting it.

    (2) Inconsistencies with Stage-I Clearance: The Stage-I clearance for the project was granted in October 2022, two years after the application was received. Monthly progress reports show that the district administration did not process any claims over forest land under the FRA in the 26 months since project sanction.

    (3) Withdrawal of Consent: Weeks after the Stage-I clearance was granted, the Tribal Council at Campbell Bay withdrew the consent granted by the Gram Sabha.

  • Nuclear Study provides major update on Plutonium Isotope Fission

    Why in the News?

    Recently a study was conducted on Prompt Fission Neutron Spectrum (PFNS) by the US. This study holds significance for design updates in India’s second stage of its nuclear power programme.

    India’s Progress in Nuclear Energy

    On March 4, India advanced to the second stage of its nuclear power programme by beginning the core-loading process of the Prototype Fast Breeder Reactor (PFBR) at the Madras Atomic Power Station in Kalpakkam. 

    India’s 3-stage Nuclear Power Program:

    Description Timeline
    Stage 1 Relies on pressurized heavy water reactors (PHWRs) using natural uranium as fuel. Initiated in the 1950s;

    Operational since the 1960s
    Stage 2 Focuses on developing fast breeder reactors (FBRs) using plutonium-239 produced in Stage 1. Initiated in the 1970s;

    Development phase
    Stage 3 Involves the development of thorium-based reactors utilizing India’s significant thorium reserves. Initiated in the late 1980s/early 1990s;

    Research & Development phase

    What is Prompt Fission Neutron Spectrum (PFNS)?

    • Definition: PFNS refers to neutrons emitted right after a Pu-240 nucleus captures a neutron but before it reaches a stable state.
    • Previous Studies: To date, only one study has investigated PFNS for Pu-240-induced fission at 0.85 mega-electron-volt (MeV). Recently, researchers in the U.S. conducted a second study with neutrons of higher energy than 0.85 MeV.
    • New Findings: The findings reveal significant differences between predicted and measured PFNS, aiding reactor designers and nuclear medicine practitioners.

    About Plutonium-240 and its Fission

    • Neutron Capture: When a Pu-239 nucleus captures a neutron, it can either undergo fission or become Pu-240.
      • Pu-240 is common in nuclear reactors and nuclear weapon test fallout.
    • Pu-240 Behavior: Pu-240 capturing a neutron typically turns into Pu-241.
      • If Pu-240 undergoes fission, there’s uncertainty about the energy of its fission products.
      • Current models use complex calculations to estimate this output.

    Do you know?

    • Plutonium is created from Uranium-238 in nuclear reactors.
    • Plutonium-239 is a weapon-grade fissile material (i.e. used to make nuclear weapons).
      • Pu-239 and Pu-240 are by-products of nuclear reactor operations and nuclear bomb explosions.

    Relevance of PFNS Study to India’s PFBR

    • PFBR Use: The PFBR uses plutonium from CANDU (Canada Deuterium Uranium) reactor spent fuel, which contains Pu-240. Reprocessed PFBR spent fuel will also contain Pu-240.
    • Importance of New Data: New data on Pu-240 behaviour is essential for improving reactor efficiency and safety.

    Production and Characteristics of Pu-240

    • Creation of Pu-239: Pu-239 is created when U-238 is exposed to neutrons in a reactor. As Pu-239 captures neutrons, it turns into Pu-240, which builds up over time.
    • Spontaneous Fission: Pu-240 undergoes spontaneous fission, emitting alpha particles, and is considered a contaminant in weapons-grade plutonium, where its composition is kept below 7%.
    • Reactor-Grade Plutonium: Plutonium with more than 19% Pu-240 is classified as reactor-grade.

    Experimental Findings on PFNS

    • Research at LANSCE: Researchers at Los Alamos Neutron Science Centre (LANSCE) conducted tests by bombarding a pure Pu-240 sample with neutrons of 0.01-800 MeV energy.
    • Detection Setup: The setup included liquid scintillators to detect emitted particles, using a small Pu-240 sample to minimize alpha particle emission.
    • Measurement Focus: They measured the energies of neutrons and other fission products, focusing on neutron-induced fission data.

  • Possible risks of “Acute Poisoning” due to high Capsaicin Levels

    Why in the News?

    Food safety authorities in Denmark have recalled three types of South Korean spicy instant noodles due to potential risks of “acute Capsaicin poisoning.”

    What is Capsaicin?

    • Capsaicin, the chemical responsible for chili pepper spiciness, is primarily found in the white membrane (placenta) of some chili peppers.
    • Mechanism of Capsaicin:
      • Capsaicin binds to TRPV1 receptors in the human body, which detect heat and pain.
      • These receptors are tricked by capsaicin into reacting as if there is a rise in temperature, causing a painful, burning sensation.
      • The body’s response includes sweating, facial redness, runny nose, teary eyes, gut cramps, and diarrhoea as it attempts to cool down and expel the perceived heat.

    Evolutionary Benefits of Capsaicin

    • While birds avoid chilies, rodents consume them.
    • Birds lack TRPV1 receptors, unlike rodents act as seed dispersers, aiding in the germination of chili seeds.
    • Capsaicin serves an evolutionary purpose by deterring mammals from eating the seeds and protecting the plant from fungi and insects.
    • Producing capsaicin is resource-intensive, making spicy chilies more vulnerable to droughts.

    Human Affinity for Spicy Foods

    • Over 3,000 chili cultivars have been bred for varying color, taste, and pungency.
    • Some experts believe humans’ love for spicy foods stems from their antimicrobial benefits, which are particularly useful in hotter climates where food spoils faster.
    • Psychologists argue that eating spicy foods is similar to thrill-seeking activities, providing a simulated risk without actual danger.

    Potential Risks of Capsaicin

    • High concentrations of capsaicin can cause heartburn, gastrointestinal pain, and diarrhoea.
    • Long-term ingestion of high levels may lead to chronic gastrointestinal disorders.
    • Capsaicin poisoning is rare due to the large amount required for toxicity, with a person needing to consume around 2.5 liters of Tabasco sauce to overdose.

  • How long is Carbon is stored in plants?

    Why in the News?

    A recent study in the Science journal indicates that the storage of carbon in terrestrial vegetation is more short-lived and more vulnerable to climate change than previously estimated.

    Carbon Absorption and Storage in Plants

    • Current models may overestimate the time carbon remains stored in plants, meaning it returns to the atmosphere sooner than previously expected.
    • Experts emphasised that while plants and forests play a crucial role in drawing down carbon dioxide, their potential is limited.
    • The study calls for a rapid reduction in fossil fuel emissions to mitigate climate change impacts.

    Key Findings:  

    • Plants and soils absorb 30% of annual carbon dioxide emissions from human activities, mitigating climate change.
    • However, there are gaps in understanding the stability and mechanisms of this carbon storage.

    Use of Radiocarbon (Carbon-14) in Research

    • Researchers used Carbon-14, a radioactive isotope, to track carbon accumulation and turnover in the terrestrial biosphere.
    • Nuclear bomb testing in the 1950s and 1960s increased atmospheric C-14 levels, providing a unique opportunity to study carbon cycling.

    Study Results

    • By analysing C-14 accumulation in plants from 1963 to 1967, researchers compared these findings to current models.
    • The analysis showed that net primary productivity (the rate of new plant tissue creation) is likely at least 80 petagrams of carbon (PgC) per year, higher than the 43-76 PgC per year predicted by current models.
    • The C-14 accumulation in vegetation during 1963-67 was 69 ± 24 ×10²⁶, suggesting a more rapid carbon cycle between the atmosphere and biosphere than previously thought.

    Back2Basics: Carbon-14 and Carbon Dating

    • Carbon dating is a widely used method for determining the age of organic materials that were once living.
    • The method is based on the radioactive decay of Carbon-14 (C-14), an isotope of carbon with an atomic mass of 14.
    • It works by measuring the ratio of C-12 to C-14 in the atmosphere, as well as in plants and animals that acquire carbon through photosynthesis or food consumption.

    The Half-Life Concept

    • Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.
    • Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

    Implications of the Study: Reforestation is inadequate

    • Today, reforestation is proposed to remove CO2 from the atmosphere, but trees do not return the CO2 to the geological layers from which the fossil fuels came.
    • This sink is transitory and this study shows us that its duration is even shorter than we thought.
