  • Supreme Court seeks government’s response on evolving ‘Project Great Indian Bustard’

    bustard

    The Supreme Court sought the government’s response about evolving a ‘Project Great Indian Bustard’ conservation program like the ‘Project Tiger’ to bring attention to the peril faced by the critically endangered bird species.

    Great Indian Bustards

    • GIBs are the largest among the four bustard species found in India, the other three being MacQueen’s bustard, lesser florican, and the Bengal florican.
    • GIBs’ historic range included much of the Indian sub-continent but it has now shrunken to just 10 percent of it. Among the heaviest birds with flight, GIBs prefer grasslands as their habitats.
    • GIBs are considered the flagship bird species of grassland.

    On the brink of extinction

    • The GIB population in India had fallen to just 150.
    • Pakistan is also believed to host a few GIBs and yet openly supports their hunting.

    Protection accorded

    • Birdlife International: uplisted from Endangered to Critically Endangered (2011)
    • Protection under CITES: Appendix I
    • IUCN status: Critically Endangered
    • Protection under Wildlife (Protection) Act: Schedule I

    Threats

    • Overhead power transmission
    • Poor vision: Due to their poor frontal vision, can’t detect powerlines in time and their weight makes in-flight quick maneuvers difficult.
    • Windmills: Coincidentally, Kutch and Thar desert are the places that have witnessed the creation of huge renewable energy infrastructure.
    • Noise pollution: Noise affects the mating and courtship practices of the GIB.
    • Changes in the landscape: by way of farmers cultivating their land, which otherwise used to remain fallow due to frequent droughts in Kutch.
    • Cultivation changes: Cultivation of cotton and wheat instead of pulses and fodder are also cited as reasons for falling GIB numbers.

    Supreme Court’s intervention

    • The Supreme Court has ordered that all overhead power transmission lines in core and potential GIB habitats in Rajasthan and Gujarat should be undergrounded.
    • The SC also formed a three-member committee to help power companies comply with the order.

    Conservation measures

    • In 2015, the Central government launched the GIB species recovery program.
    • Under the program, the WII and Rajasthan Forest departments have jointly set up conservation breeding centers where GIB eggs are harvested from the wild.
    • They have been incubated artificially and hatchlings raised in a controlled environment.

  • In news: Exercise Yudh Abhyas

    China expressed concern over the India-US joint military exercise Yudh Abhyas being held in Uttarakhand, about 100 km from the LAC.

    Exercise Yudh Abhyas

    • Exercise Yudh Abhyas is the largest running joint military training and defence cooperation endeavour between India and the US.
    • The exercise aims at enhancing understanding, cooperation and interoperability between the two armies.
    • Interestingly, this is the only India-US service exercise continuing in bilateral format.

    Why in news?

    • The disengagement of troops is still under process after several rounds of talks between India and China.
    • Since beginning in May 2020, Chinese and Indian forces faced off in clashes with rocks, batons, and clubs wrapped in barbed wire at multiple locations along the LAC.
    • Differing perceptions of border demarcations along the LAC is the reason behind.
    • Each country seeks the withdrawal of the other’s forces and a return to the pre-stand-off conditions, but neither China nor India agreed to the conditions.

  • Municipal Solid Waste (MSW) in India

    Solid Waste

    Click and get your FREE Copy of CURRENT AFFAIRS Micro Notes

    Context

    • A recent report titled ‘EnviStats India 2022’, published by the Ministry of Statistics and Programme Implementation, has highlighted the herculean challenge of disposing of the solid waste generated by the States without harming the environment.

    What is the report all about?

    • Source and destination of solid waste: By taking Delhi as an example, the report has calculated the “physical supply and use tables” to capture the source and destination of all types of solid waste in the capital city.
    • Data from government sources: Data were collected from all the five Urban Local Bodies and the Delhi Pollution Control Committee pertaining to 2020-21.

    Case study of Delhi

    • Over 40 lakh tonnes of Municipal Solid Waste (MSW): Municipal solid waste includes garbage (highly decomposable material such as food), trash (bulky items such as tree branches or old appliances), and rubbish (slowly decomposing items such as paper, glass, or metal).
    • Households are largest contributors: According to the report, about 85% of MSW in Delhi was generated by households and 15% by shops and restaurants.
    • High C & D waste: That year, over 13 lakh tonnes of construction and demolition waste were also generated in the city along with over 5.4 lakh tonnes of plastic waste, about 11 thousand tonnes of bio-medical waste, and 610 tonnes of e-waste.
    • Hazardous waste: Delhi also generated 3,239 tonnes of hazardous waste. Hazardous waste is typically sludge from factories, industrial manufacturing process wastes and batteries.

    How the waste is disposed-off?

    • Largest part went to landfills: Half the municipal solid waste went to landfills and the other half was recycled and reused.
    • Incineration: About 35% of bio-medical waste was incinerated, while the entire share of construction and demolition waste was recycled. While bio-medical waste is incinerated, the ash generated after the process is sent to the landfills.
    • No information on E-waste: It is not known how e-waste is disposed of as there is no treatment and disposal facility available in Delhi for e-waste.
    • Plastic into energy: According to the report, of the 610 tonnes of e-waste generated in 2020-21, refurbish collector collected 28.6 tonnes and bulk consumers collected the rest. Notably, about 22% of plastic waste is converted into energy, while 37% is taken to landfills.

    Solid Waste

    How Municipal solid waste is taken care in others states of India?

    • Amount of waste processed: Across India, 68% of the MSW generated is processed. Himachal Pradesh leads the list with 98% of MSW getting processed, followed by Chhattisgarh at 93%.
    • West Bengal poor performer: In contrast, West Bengal processed only 9%. These data were of November 2020. In 2018-19, an average of 2.5 tonnes of plastic was generated per 1,000 population in India.
    • How biomedical waste is treated: Across India, 87% of biomedical waste was treated. Seventeen States and five Union Territories have already achieved 100% bio-medical waste treatment, while in Bihar and Chhattisgarh just 29% of it got treated, respectively. Close to 614 tonnes of biomedical waste was generated per day in India in 2018.
    • Hazardous waste is poorly treated: Across India, only 45% of the hazardous waste generated was recycled/utilised. Most States lag in this indicator. Of the 30 States analysed, in 13, less than 50% was recycled/utilised; and in 22 of them, less than 75% was recycled/utilised. These data pertain to the 2018-19 period. The hazardous waste generated in the country per 1,000 population was 8.09 metric tonnes in 2018.

    Solid Waste

    Municipal solid waste management rules 2016

    • Segregation at source: The new rules have mandated the source segregation of waste in order to channelize the waste to wealth by recovery, reuse and recycle. Waste generators would now have to now segregate waste into three streams- Biodegradables, Dry (Plastic, Paper, metal, Wood, etc.) and Domestic Hazardous waste (diapers, napkins, mosquito repellents, cleaning agents etc.) before handing it over to the collector.
    • Collection and disposal of sanitary waste: The manufacturers or brand owners of sanitary napkins are responsible for awareness for proper disposal of such waste by the generator and shall provide a pouch or wrapper for disposal of each napkin or diapers along with the packet of their sanitary products.
    • Collect Back scheme for packaging waste: As per the rules, brand owners who sale or market their products in packaging material which are non‐biodegradable, should put in place a system to collect back the packaging waste generated due to their production.
    • User fees for collection: The new rules have given power to the local bodies across India to decide the user fees. Municipal authorities will levy user fees for collection, disposal and processing from bulk generators.
    • Waste processing and treatment: It has been advised that the bio-degradable waste should be processed, treated and disposed of through composting or bio-methanation within the premises as far as possible and the residual waste shall be given to the waste collectors or agency as directed by the local authority.

    Conclusion

    • EnviStats India 2022 report highlights the positive progress by India in solid waste management. However, challenges still persist, hazardous and e- waste, Landfills and incineration need to be reduced significantly which are causing the pollution.

    Mains Question

    Q. Briefly discuss the solid waste management rule 2016. Analyse the performance of various state on SWM based on ‘EnviStats India 2022’ report.

  • Removing the Menopause taboo

    Menopause

    Click and get your FREE Copy of CURRENT AFFAIRS Micro Notes

    Context

    • Recent announcement by the National Health Services (NHS) in the UK that menopausal women on their staff will be able to work out of the home should their symptoms require it, is about path-finding and working the middle ground in the workplace.
    • NHS chief Amanda Pritchard said that other employers should follow suit to help middle-aged women “thrive” at work and those “silently suffering” should not be expected to “grin and bear it.”

    Background: A menopausal taboo questions women’s potential?

    • The context opening up the conversation at least: If nothing, such a move has at least been a conversation starter about what has been so far a taboo in the workplace and a reason to hive off women than allow them ease of thriving.
    • Misconception that women may not work efficiently: Yet, just like pregnancy, the end of a woman’s reproductive cycle is seen as her losing energy, drive, desire, stamina, excitement and capability, in short, a cliff-jumping drop of her value in wisdom and experience.
    • On the contrary most women do best in this phase: Ironically, this phase, between the mid-40s to the mid-50s, is where you would find most women reaching the top, having battled biases of motherhood, leaving no questions unanswered on their competence and commitment.
    • Yet questions raised about her worth and never about her comfort: When a woman employee crosses the age bar, she has to prove her worth all over again. Is she as good, is she capable of thinking afresh, can she pull long hours? It is never about “is she comfortable?” Sadly, her body of work matters little.
    • Constant pressure on women to prove the worth forces to overlook themselves: And it is this constant pressure to feed expectations that forces even confident women to overwork themselves to stay relevant despite those painful bouts of endometriosis, heavy bleeding, hot flushes, insomnia, fatigue, anxiety, hypertension and palpitations. All of these are terribly debilitating but manageable with a little breathing space.

    What is menopause?

    • Menopause is a point in time 12 months after a woman’s last period.
    • Menopausal transition may commonly be referred to as “menopause,” true menopause doesn’t happen until one year after a woman’s final menstrual period.

    Menopause

    Menopausal transition

    • The years leading up to that point, when women may have changes in their monthly cycles, hot flashes, or other symptoms, are called the menopausal transition or perimenopause.
    • The menopausal transition most often begins between ages 45 and 55.
    • It usually lasts about seven years but can be as long as 14 years.The duration can depend on lifestyle factors such as smoking, age it begins, and race and ethnicity.
    • During perimenopause, the body’s production of estrogen and progesterone, two hormones made by the ovaries, varies greatly.
    • Estrogen is used by many parts of a woman’s body. As levels of estrogen decrease, one could have various symptoms. Many women experience mild symptoms that can be treated by lifestyle changes. Some women don’t require any treatment at all.

    Did you know?

    • According to the Harvard Medical School, a post-menopausal woman’s symptoms of a heart attack are “different from a man’s and she’s much more likely than a man to die within a year of having a heart attack.
    • Women also don’t seem to fare as well as men do after taking clot-busting drugs or undergoing certain heart-related medical procedures.”

    What are the signs and symptoms of menopause?

    • Change in your period: Women periods may no longer be regular. They may be shorter or last longer. Bleeding may be more or less than usual.
    • Hot flashes: Many women have hot flashes, which can last for many years after menopause. They may be related to changing estrogen levels. A hot flash is a sudden feeling of heat in the upper part or all of the body.
    • Disturbed Sleep: Around midlife, some women start having trouble getting a good night’s sleep.
    • Vaginal health and sexuality: After menopause, the vagina may become drier, which can make sexual intercourse uncomfortable. Women may find that the feelings about sex are changing.
    • Mood changes: Women might feel moodier or more irritable around the time of menopause. Scientists don’t know why this happens. It’s possible that stress, family changes such as growing children or aging parents, a history of depression, or feeling tired could be causing these mood changes.
    • Body features may alter: The body begins to use energy differently, fat cells change, and women may gain weight more easily. Women might have memory problems as well as joints and muscles could feel stiff and achy.

    Menopause

    How menopause affects Women health?

    • Severe and unexpected physiological challenges: As the hormone oestrogen dips, it pushes up bad cholesterol or LDL levels, raising their cardiac risk more than men. They even have higher concentrations of total cholesterol than men.
    • Psychological challenges: Strangely even women in the menopausal period are not concerned about their life risks as they get caught in the vanity trap and worry more about issues related to their body image, sexuality and self-esteem. Some rush into Menopausal Hormone Therapy (MHT), which is not quite the elixir of youth, and often has deadly side effects like uterine and breast cancer. These elevated risk factors, however, can be reduced if women were to be less stressed about tiring out their bodies to prove a point.

    The conversation over the menopause

    • In India: However, in India, where motherhood is seen as a major career impediment for women, menopause is a far cry, often bottled up in hushed conversations among women in the office loo.
    • Progressive step in UK: The UK Parliament commissioned a survey that showed how one in three women were missing work due to menopause.
    • Italy and Australia: Italy and Australia are debating about including menopause in work ethics norms.
    • EU parliament: Recently, the EU Parliament put out a statement, saying, “The failure to address menopause as a workplace issue is increasingly leading to insufficient protection of female workers and the early exit of women from labour markets, and thereby increasing the risk of women’s economic dependence, poverty and social exclusion, contributing to the loss of women’s knowledge, skills and experience, and leading to significant economic losses.”

    Menopause

    Conclusion

    • Considering that women will go through this biological phase at least for eight years in their work life, a little sensitivity to their concerns would matter more than a debate on whether they should be allowed extra benefits.

    Mains Question

    Q. What is menopausal transition? Menopause at work place often seen as taboo to talk, In this background, highlight the changes taking place.

  • Launching of the Digital Rupee Pilot Project

    rupee

    The Reserve Bank of India (RBI) has announced that the first pilot for the retail version of the digital Rupee (e₹-R) would be introduced on December 1, 2022.

    Where would be the pilot project launched?

    • The pilot will initially cover the four cities of Mumbai, New Delhi, Bengaluru, and Bhubaneswar, where customers and merchants will be able to use the digital rupee (e₹-R), or e-rupee.
    • Four banks will be involved in the controlled launch of the digital currency in these four cities: State Bank of India, ICICI Bank, Yes Bank, and IDFC First Bank.
    • The service will be subsequently extended to the cities of Ahmedabad, Gangtok, Guwahati, Hyderabad, Indore, Kochi, Lucknow, Patna, and Shimla.
    • Four more banks — Bank of Baroda, Union Bank of India, HDFC Bank, and Kotak Mahindra Bank — will join the pilot.

    What is Central Bank Digital Currency (CBDC)?

    • CBDC / Digital Rupee is a RBI bank-issued digital currency which is backed by some kind of assets in the form of either gold, currency reserves, bonds and other assets, recognised by the central banks as a monetary asset.
    • The present concept of CBDCs was directly inspired by Bitcoin, but a CBDC is different from virtual currency and cryptocurrency.
    • Cryptocurrencies are not issued by a state and lack the legal tender status declared by the government.

    What are the types of Digital Rupee?

    • Based on the usage and the functions performed by the digital rupee and considering the different levels of accessibility, CBDC can be demarcated into two broad categories:
    1. General purpose (retail) (CBDC-R): It is an electronic version of cash primarily meant for retail transactions. It will be potentially available for use by all — private sector, non-financial consumers and businesses — and can provide access to safe money for payment and settlement as it is a direct liability of the central bank.
    2. Wholesale (CBDC-W): It is designed for restricted access to select financial institutions. It has the potential to transform the settlement systems for financial transactions undertaken by banks in the government securities (G-Sec) segment, inter-bank market and capital market more efficiently and securely in terms of operational costs, use of collateral and liquidity management.

    What are the forms of CBDC?

    The central bank says e-rupee, or CBDC, can be structured as token-based or account-based.

    1. Token-based CBDC: It would be a bearer instrument like banknotes, meaning whosoever holds the tokens at a given point in time would be presumed to own them. In this, the person receiving a token will verify that his ownership of the token is genuine. It is viewed as a preferred mode for CBDC-R as it would be closer to physical cash.
    2. Account-based CBDC: It would require maintenance of record of balances and transactions of all holders of the CBDC and indicate the ownership of the monetary balances.  In this case, an intermediary will verify the identity of an account holder. This system can be considered for CBDC-W.

    What’s the model for issuance?

    • There are two models for issuance and management of CBDCs under the RBI’s consideration — direct model (single tier model) and indirect model (two-tier model).
    • Direct model: Here the central bank will be responsible for managing all aspects of the digital rupee system such as issuance, account-keeping and transaction verification.
    • Indirect model: It would be one where the central bank and other intermediaries (banks and any other service providers), each play their respective role. In this model, the central bank will issue CBDC to consumer’s indirectly through intermediaries and any claim by consumers will be managed by the intermediary.

  • NITI Aayog launches CCUS policy framework

    niti

    The NITI Aayog has prepared a report on the policy framework for Carbon Capture Utilisation and Storage (CCUS).

    What is Carbon capture, utilization, and storage (CCUS)?

    • It is the process of capturing carbon dioxide emissions and either using them to make things such as building materials (utilization) or permanently storing those thousands of feet below the surface (storage).
    • Capturing carbon dioxide from industrial operations before it has a chance to enter the atmosphere helps reduce emissions, as does removing it directly from the air.
    • The carbon dioxide is then reused or sent through an injection well deep underground where it is locked away safely and permanently.
    • It’s a straightforward concept that takes infrastructure and policy considerations to implement, and Chevron is committed to making it work.

    Steps involved in CCUS

    • Capturing the carbon dioxide for storage: The CO2 is separated from other gases produced in industrial processes, such as those at coal and natural-gas-fired power generation plants or steel or cement factories.
    • Transport: The CO2 is then compressed and transported via pipelines, road transport or ships to a site for storage.
    • Storage: Finally, the CO2 is injected into rock formations deep underground for permanent storage.

    What has NITI Aayog identified?

    • CCUS has a critical role to play for the country to halve CO2 emissions by 2050.
    • Key challenge would be to reduce the cost of the mechanisms to implement the technology.
    • CCUS could enable the production of clean products while utilising rich endowments of coal, reducing imports and thus leading to a self-reliant India economy.
    • It has an important role to play in enabling sunrise sectors such as coal gasification and the nascent hydrogen economy in India.

    Key sectors identified for carbon utilization

    • Green urea: Green urea can be produced from the captured CO 2 and cost-competitive green hydrogen, from renewable energy-based electrolysis of water. Green urea can replace/complement the traditional LNG/NG-based production and import of ammonia and urea.
    • F&B applications: CO2 is utilized in F&B applications such as carbonated drinks, dry ice, and modified atmosphere packing; however, the scales are much lower compared to green urea.
    • Building materials (concrete and aggregates): There is a large market for aggregates and concrete in a developing country like India, providing a pathway for utilizing CO2 for producing building materials through concrete curing and aggregate formation. In these applications, CO2 is injected in a liquid state without any conversion, thus reducing the energy requirements.
    • Chemicals (methanol and ethanol): Conversion of CO2 to methanol and ethanol from CO2 is proven at a commercial scale in different parts of the world.

    Why such move?

    • India’s per capita CO2 emissions were about 1.9 tonnes per annum, which was less than 40% of the global average and about one-fourth of that of China.
    • India needs a sustainable solution for the decarbonization of sectors that contribute to 70% of emission.

    Why CCUS is important?

    • CCUS helps reduce the carbon intensity of industrial operations and is a critical component of meeting the global net-zero ambitions of the Paris Agreement.
    • In fact, the Intergovernmental Panel on Climate Change notes in its Global Warming of 1.5 °C report that achieving net-zero emissions by 2050 isn’t possible without ambitious mitigation action.

  • Analyzing the approval of DMH-11

    DMH-11

    Context

    • Concerns regarding the recent recommendation for approval for the environmental release of genetically engineered (GE) mustard (“DMH-11 hybrid”) in India. The recommendation was made by the Genetic Engineering Appraisal Committee (GEAC).

    Click and get your FREE Copy of CURRENT AFFAIRS Micro Notes

    What is Dhara Mustard hybrid (DMH-11)?

    • DMH-11 is a hybrid variant of mustard developed by researchers at The Centre for Genetic Manipulation of Crop Plants, at the University of Delhi.
    • It is a hybrid variant that was developed without transgenic technology.
    • DMH-11 is a result of a cross between two varieties: Varuna and Early Heera-2. Such a cross wouldn’t have happened naturally and was done after introducing genes from two soil bacterium called barnase and barstar.
    • The result is DMH-11 (where 11 refers to the number of generations after which desirable traits manifest) that not only has better yield but is also fertile. DMH-11 is a transgenic crop because it uses foreign genes from a different species.

    DMH-11

    What are the concerns?

    • Not sufficient consideration: The potentially harmful long-term ecological and economic consequences of releasing DMH-11 have not received sufficient consideration.
    • Details of trials not made public: Details of the mandatory trials to ensure food and environmental safety which is a prerequisite before environmental release have not been made public.
    • A long-term assessment is yet to be done: a detailed long-term assessment of the potential social and economic benefits of using DMH-11, vis-à-vis its potential drawbacks, remains to be made. Without minimizing the importance of the last two aspects, the present note is restricted to highlighting the first aspect.

    DMH-11

    Examining the central Feature of DMH-11 

    • Gene for herbicide resistance (HT): A central feature of DMH-11 is that it carries a gene for herbicide resistance (also termed herbicide tolerance or HT). This fact has not received appropriate consideration.
    • Negatives outcomes: The deployment of herbicide-resistant or HT crops has been accompanied by deleterious outcomes in several places including the US, Australia, and Canada (so-called developed countries) as well as Argentina (a developing country).
    • Consequences of herbicide resistant weeds: The most well-established harmful consequence has been the spread of herbicide-resistant weeds across large tracts of agricultural land, which can spell disaster for the normal crop.

    Critical and technical analysis of DMH-11

    • On the use of Basta herbicide: The developers of DMH-11 have stated in their food and environmental safety assessment submission of 2016 that “Although GE mustard hybrid DMH-11 contains the bar gene conferring resistance to the herbicide Basta (phosphinothricin), Basta herbicide is required to be used only by seed producer for hybrid seed production (and) farmers are not required to spray Basta in the hybrid GE DMH-11 for weed control”.
    • Certain conditions placed by GEAC for environmental release of DMH-11:
    • The GEAC in its recommendation made on October 18 for environmental release of DMH-11 has accepted this position and also placed certain conditions for environmental release.
    1. Usage only under control: Usage of any formulation of herbicide is recommended only under controlled and specified conditions exclusively for hybrid seed production.
    2. Requires necessary permission: Usage of any formulation of herbicide is not permitted for cultivation in the farmer’s field under any situation and such use would require the necessary permission as per procedures and protocols of safety assessment of insecticides/herbicides by CIB&RC (Central Insecticide Board and Registration Committee).”
    • Knowing the facts GEAC ignoring the reports: In other words, GEAC assumes that farmers will use DMH-11 without adding herbicideeven though they know that it carries a gene for herbicide resistance. It ignores the known fact that there have been numerous recent reports in the Indian media of the illegal use of unapproved herbicide-resistant crops, which has been brought to the notice of the government.
    • Registers usage on a crop-wise basis is not enough: GEAC has considered the possible use of herbicide with DMH-11 merely as a matter of herbicide usage and referred its approval to the CIB&RC, which registers usage of herbicides on a crop-wise basis. It is not enough for GEAC to merely refer it for chemical registration since the CIB&RC is not the competent body for recommending approval of GM crops.
    • HT technology is different from conventional herbicides:
    1. On multiple counts, HT technology is qualitatively different from the conventional use of herbicides.
    2. They include the levels of herbicide used, which is much higher than in conventional use; its effect on the crop which is engineered to be resistant to the herbicide and thereby to tolerate much higher levels of herbicide and its agro-ecological impact including on agricultural biodiversity and insect populations.
    3. The scope of issues connected to use of herbicide with a herbicide-resistant crop places it squarely within the purview of GM regulation (that is, GEAC).

    Remarks: Developers Intent may not define how it is likely to be used

    • Notwithstanding the statement of the developers and its implicit acceptance by GEAC, DMH-11 does meet the definition of an HT crop.
    • The answers to two questions show this. Is DMH-11 herbicide tolerant? Yes. Is it a crop? Yes.
    • The intent of the developer on how it is meant to be used does not determine how it is actually likely to be used, especially if that usage appears to confer obvious advantages.
    • HT technology involves the use of a herbicide in far higher amounts than conventional herbicide treatments, high enough to kill all weeds in the field, leaving only the engineered crop to grow. Thereby, it replaces all other weed control measures.

    Conclusion

    • HT may be effective for a few years. But basic evolutionary considerations, as well as experience in other countries, shows that it imposes strong selective pressure for resistant weeds to emerge. They invariably do so in the course of time and spread rapidly. HT offers short-term benefits at the cost of long-term sustainability. Long term assessment is necessary before clearing its way.

  • In news: Kerala’s SilverLine Project

    Protests are taking place across Kerala against SilverLine, a semi high-speed railway project that envisages trains running at 200 km/h between the state’s northern and southern ends.

    What is the SilverLine project?

    • The proposed 529.45-km line will link Thiruvananthapuram in the south to Kasaragod in the north, covering 11 districts through 11 stations.
    • KRDCL, or K-Rail, is a joint venture between the Kerala government and the Union Ministry of Railways created to execute this project.
    • The deadline for the project, being executed by the Kerala Rail Development Corporation Limited (KRDCL), is 2025.

    Features of the Project

    • The project will have trains of electric multiple unit (EMU) type, each with preferably nine cars extendable to 12.
    • A nine-car rake can seat a maximum of 675 passengers in business and standard class settings.
    • The trains can run at a maximum speed of 220 km/hr on a standard gauge track, completing journeys in either direction in fewer than four hours.
    • At every 500 metres, there will be under-passages with service roads.

    Need for the SilverLine project

    • Time saving: On the existing network, it now takes 12 hours. Once the project is completed, one can travel from Kasaragod to Thiruvananthapuram in less than four hours at 200 km/hr.
    • Old infrastructure: Existing railway infrastructure in Kerala cannot meet the demands of the future.
    • Terrain limitations: Most trains run at an average speed of 45 km/hr due to a lot of curves and bends on the existing stretch.
    • De-trafficking: The project can take a significant load of traffic off the existing stretch and make travel faster for commuters, which in turn will reduce congestion on roads and help reduce accidents.
    • Others: The project would reduce greenhouse gas emissions, help in expansion of Ro-Ro services, produce employment opportunities, integrate airports and IT corridors, and enable faster development of cities it passes through.

    Present status of the Project

    Ans. Land acquisition is underway

    • The state government has begun the process of land acquisition after the cabinet approved it this year.
    • As part of the first stage of acquisition, local revenue and K-Rail officials are on the ground, demarcating land and placing boundary stones.
    • This is done to give the officials a sense of how much private land will have to be acquired and the number of families who will be displaced.

    Issues with the Project

    • Political rhetoric: All political parties have been spearheading separate protests.
    • Huge capital requirement: They argue that the project was an “astronomical scam in the making” and would sink the state further into debt.
    • Displacement of families: The project was financially unviable and would lead to the displacement of over 30,000 families.
    • Ecological damage: It would cause great environmental harm as its route cuts through precious wetlands, paddy fields and hills.
    • Flood hazard: The building of embankments on either side of the major portion of the line will block natural drainage and cause floods during heavy rains.

  • SARAS 3 Telescope gives clues to first stars, galaxies of universe

    saras

    India’s SARAS radio telescope has helped scientists determine the properties of the earliest radio luminous galaxies formed 200 million years after the Big Bang, a period known as the Cosmic Dawn.

    SARAS 3 Telescope

    • SARAS stands for Shaped Antenna measurement of the background Radio Spectrum 3 (SARAS) telescope.
    • It is an indigenously designed and built at Raman Research Institute and was deployed over Dandiganahalli Lake and Sharavati backwaters, located in Northern Karnataka, in early 2020.

    What have the researchers found?

    • Researchers have been able to determine properties of radio luminous galaxies formed just 200 million years post the Big Bang, a period known as the Cosmic Dawn.
    • These are the masses of the first generation of galaxies that are bright in radio wavelengths.
    • This helps provide an insight into the properties of the earliest radio loud galaxies that are usually powered by supermassive black holes.

    What is Cosmic Dawn?

    • The ignition of the first stars marks the end of the Dark Ages and the beginning of our “Cosmic Dawn,” some 100 million years after the Big Bang.
    • For the first time, our universe began shining with a light other than the afterglow of the Big Bang.
    • SARAS 3 had improved the understanding of astrophysics of Cosmic Dawn by telling astronomers that less than 3% of the gaseous matter within early galaxies was converted into stars.
    • It found that the earliest galaxies that were bright in radio emission were also strong in X-rays, which heated the cosmic gas in and around the early galaxies.

  • What is Bluebugging?

    Bluebugging

    Cybersecurity experts note that apps that let users connect smartphones or laptops to wireless earplugs can record conversations, and are vulnerable to hacks through a process called Bluebugging.

    What is Bluebugging?

    • It is a form of hacking that lets attackers access a device through its discoverable Bluetooth connection.
    • Once a device or phone is blue-bugged, a hacker can listen to the calls, read and send messages and steal and modify contacts.
    • It started out as a threat for laptops with Bluetooth capability. Later hackers used the technique to target mobile phones and other devices.
    • Independent security researcher Martin Herfurt blogged about the threat of bluebugging as early as 2004.
    • He noted that the bug exploited a loophole in Bluetooth protocol, enabling it to download phone books and call lists from the attacked user’s phone.

    How does bluebugging hack devices?

    • Bluebugging attacks work by exploiting Bluetooth-enabled devices.
    • The device’s Bluetooth must be in discoverable mode, which is the default setting on most devices.
    • The hacker then tries to pair with the device via Bluetooth. Once a connection is established, hackers can use brute force attacks to bypass authentication.
    • They can install malware in the compromised device to gain unauthorised access to it.
    • Bluebugging can happen whenever a Bluetooth enabled device is within a 10-metre radius of the hacker.
    • However, according to a blog by VPN service provider NordVPN, hackers can use booster antennas to widen the attack range.

    Why is it a big threat?

    • Even the most secure smartphones like iPhones are vulnerable to such attacks.
    • Any app with access to Bluetooth can record users’ conversations with Siri and audio from the iOS keyboard dictation feature when using AirPods or Beats headsets, some app developers say.
    • Through Bluebugging, a hacker can gain unauthorised access to these apps and devices and control them as per their wish.

    How can one prevent bluebugging?

    Here are some of the ways to prevent bluebugging-

    1. Turning off Bluetooth and disconnecting paired Bluetooth devices when not in use,
    2. Updating the device’s system software to the latest version,
    3. Limiting the use of public Wi-Fi, and
    4. Using VPN as an additional security measure
