  • James Webb telescope : The most powerful space telescope

    James Webb telescopeContext

    • Much of the universe remains unknown. The James Webb telescope will hopefully provide a powerful window to help resolve some of the cosmos’s many mysteries.

    What is James Webb Space Telescope (JWST)?

    • It is a space telescope being jointly developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
    • It has taken 30 years and $10bn to develop, and is being described as one of the grand scientific endeavors of the 21st Century.

    Where it is placed?

    • The James Webb Space Telescope will not be in orbit around the Earth, like the Hubble Space Telescope is – it will actually orbit the Sun, 1.5 million kilometres (1 million miles) away from the Earth at what is called the second Lagrange point or L2.

    Mission

    • It will be “a giant leap forward in quest to understand the Universe and our origins”, as it will examine every phase of cosmic history: from the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own Solar System.

    james webb telescope Special features of JWST

    • Time machine in space: Powerful space telescopes, like JWST or the Hubble Telescope, are often called time machines because of their ability to view very faraway objects. The light coming from those objects, stars or galaxies, which is captured by these telescopes, began its journey millions of years earlier. Essentially, what these telescopes see are images of these stars or galaxies as they were millions of years ago. The more distant the planet or star, the farther back in time are the telescopes able to see.
    • Farthest from Earth: James Webb telescope will also be positioned much deeper into space, about a million miles from Earth, at a spot known as L2. It is one of the five points, known as Lagrange’s points, in any revolving two-body system like Earth and Sun, where the gravitational forces of the two large bodies cancel each other out.
    • Engineering marvel: JWST has one large mirror, with a diameter of 21 feet (the height of a typical two-storey building), that will capture the infra-red light coming in from the deep universe while facing away from the Sun.

    What is the goal of this telescope?

    • The telescope will be able to see just about anything in the sky.
    • However, it has one overriding objective – to see the light coming from the very first stars to shine in the Universe.
    • These pioneer stars are thought to have switched on about 100-200 million years after the Big Bang, or a little over 13.5 billion years ago.
    • James Webb telescope will be picking out groupings of these stars.

    james webb telescope Its significance

    • It is widely expected to unveil many secrets of the universe, particularly those related to the Formation of stars and galaxies in the early period the first few hundred million years after the Big Bang.
    • Some have called James Webb telescope  the “telescope that ate astronomy”.
    • It is said to look back in time to the Dark Ages of the universe.

    Conclusion

    • The universe is vast and most of it is unknown. We hope that the James Webb telescope, over its lifetime would provide us with a powerful window to help resolve some of the many mysteries of the cosmos and make it a little bit more comprehensible.

    Mains question

    Q. What is James Webb telescope experiment? Do you think it shades light on dark matter? Explain.

  • Nationwide Crackdown on PFI

    pfi

    The National Investigation Agency (NIA) has launched a massive nationwide search operation in connection with anti-terror activities linked to the Popular Front of India-PFI.

    What is the Popular Front of India (PFI)?

    • The PFI was created in 2007 through the merger of three radicalists organisations in southern India, the National Democratic Front in Kerala, the Karnataka Forum for Dignity, and the Manitha Neethi Pasarai in Tamil Nadu.
    • A decision to bring the three outfits together was taken in November 2006 at a meeting in Kozhikode in Kerala.
    • The formation of the PFI was formally announced at a rally in Bengaluru during what was called the “Empower India Conference” on February 16, 2007.

    Agenda of the PFI

    • The PFI has projected itself as an organisation that fights for the rights of minorities, Dalits, and marginalised communities.
    • It has frequently targeted the alleged anti-people policies of the State even as these mainstream parties have accused one another of being in cahoots with the PFI to gather the support of Muslims at the time of elections.
    • The PFI has itself never contested elections.

    Parallel organizations to PFI

    • In 2009, a political outfit named Social Democratic Party of India (SDPI) evolved out of the PFI, with the aim of taking up the political issues of Muslims, Dalits, and other marginalised communities.
    • The SDPI’s stated goal is advancement and uniform development of all the citizenry including Muslims, Dalits, Backward Classes and Adivasis and to share power fairly among all the citizens.
    • The PFI is a key provider of ground workers for the SDPI’s political activities.

    Why is PFI under crackdown?

    (1) Links to terror outfits

    • Many volunteers of PFI are allegedly involved in terror funding, organising training camps, and radicalising people to join proscribed organisations.
    • It has been involved in carrying out social and Islamic religious work among Muslims on the lines of the work done by right-wing groups.
    • The PFI does not maintain records of its members, and it has been difficult for law enforcement agencies to pin crimes on the organisation after making arrests.

    (2) Promoting Radicalization

    • The outfit is hostile to the consolidation across the country and the rise of a single non-secular party as the nation’s pre-eminent political and ideological force.
    • The post-2014 political landscape and the self-alienation of minorities has further pushed sections of the community towards groups like the PFI.
    • The outfit is also said to have a large number of supporters in Gulf countries who contribute handsomely to its kitty, something which is under the scanner of investigating agencies.

    (3) Hostility against state mechanism

    • Starting out as an organisation primarily rooted in Kerala, Karnataka and Tamil Nadu, the PFI has spread its wings far and wide, with a presence in at least 18 states.
    • It has found particularly fertile ground in parts of Uttar Pradesh and Assam.
    • Authorities have accused the outfit of instigating and funding protests against the CAA and the National Register of Citizens.

    (4) Barbarism in the name of religion

    • The PFI has had the most visible presence in Kerala, where it has been repeatedly accused of murder, rioting, intimidation, and having links with terrorist organisations.
    • The Kerala government affidavit said PFI activists were involved in 27 cases of MURDER, mostly of CPM and RSS cadres, and that the motives were highly communal.

  • Adani’s global footprint and India’s infrastructure diplomacy  

    infrastructure diplomacyContext

    • From mines to ports and logistics, the Adani conglomerate has been expanding across sectors, regions. This has gone hand in hand with India’s diplomatic and strategic outreach towards infrastructure diplomacy.

    What is infrastructure?

    • Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function.

    What are the features of infrastructure?

    • Power and the source of its production such as coal and oil;
    • Roads and road transport;
    • Railways;
    • Communication, especially telecommunication;
    • Ports and airports; and.
    • For agriculture, irrigation constitutes the important infrastructure.

    infrastructure diplomacyWhat is infrastructure diplomacy?

    • Infrastructure diplomacy is to promote infrastructure cooperation and economic ties overseas through political means and to enhance political trust between countries via collaboration in infrastructure development.

    Why in news?

    • “Several foreign governments are now approaching us to work in their geographies and help build their infrastructure. Therefore, in 2022, we also laid the foundation to seek a broader expansion beyond India’s boundaries,” chairman and founder of the Adani group Gautam Adani,now the world’s third-richest person.

    infrastructure diplomacyBackground

    • Foreign presence much earlier: In fact, the Adani group had been scouting abroad much earlier. Since 2010, the Adani group has been in Australia, developing the Carmichael coal mine in Queensland.
    • A greenfield multi-purpose port: In 2017, Adani Ports and Special Economic Zones (Ltd) signed an MoU for a greenfield multi-purpose port for handling containers at Carey Island in Selangor state, about 50 km southwest of Kuala Lumpur.

    What is situation now?

    • Company pursue international infrastructure projects aggressively: The last two years, however, have seen the company pursue international infrastructure projects aggressively. In May 2022, APSEZ made a winning bid of $1.18 billion for Israeli state-owned Haifa Port, jointly with Israeli chemicals and logistics firm Gadot.
    • Strategic joint investments: In August this year, APSEZ and Abu Dhabi’s AD Ports Group signed MoU for “strategic joint investments” in Tanzania. The new ASEZ-AD MoU will look at a bouquet of infrastructure projects besides Bagamoyo in the East African Indian Ocean nation — rail, maritime services, digital services and industrial zones.
    • India’s strategic objectives than has been possible so far: Is it just a coincidence that Adani’s global expansion closely shadows the Chinese footprint along its Belt and Road Initiative? Or is it that as Delhicompetes with China for influence in the neighbourhood and beyond, the Adani group’s size, resources and capacity are seen as a key element in achieving India’s strategic objectives than has been possible so far.
    • India’s infrastructure diplomacy: Is now becoming identified the world over with one company.
    • Public and private investment to bridge gaps: For the Adani group, described as India’s biggest ports and logistics company, there couldn’t be a better time. As the Quad grouping of Australia, India, Japan, and the US, competes with China in the Indo-Pacific, it has committed “to catalyse infrastructure delivery” by putting more than $50 billion on the table for “assistance and investment” in the Indo-Pacific over the next five years and “drive public and private investment to bridge gaps”.

    infrastructure diplomacyImplications of infrastructure diplomacy

    • Win-Win deal: Adani’s new “no-hands” model of doing business with neighbours a power plant in Jharkhand, exporting all its output to Bangladesh has been seen as a “win-win” deal.
    • Economic interests lie at the heart of geopolitics: The link between diplomacy and commercial interests has generated its share of debate, especially in the US, where its diplomats, intelligence agencies and military interventions abroad have actively pushed the interests of big business first the hunt for cheaper raw materials, then for markets abroad, then to shift industry where manpower was cheaper. As seen in the new age trading blocs the US-led IPEF, and the Chinese dominated RCEP economic interests lie at the heart of geopolitics.

    Conclusion

    • At a time when global rivalries are growing sharper in the shadow of the war in Europe, and as India looks out for its own interests, pushing powerful corporates to the centre-stage of its diplomacy, whether it is to build ports, buy or sell weapons or make chips, is inevitable.

    Mains question 

    Q. Economic interests lie at the heart of geopolitics. Analyse this statement in context of India’s active push for infrastructure diplomacy by including private conglomerates like Adani in it.

  • Left wing extremism

    mao

    The Maoist movement is on the ebb on the Andhra Pradesh-Odisha boundary, with its cadre and militia strength heavily depleted.

    Who are the Maoists?

    • Maoism is a form of communism developed by Mao Zedong.
    • It is a doctrine to capture State power through a combination of armed insurgency, mass mobilization and strategic alliances.
    • The Maoists also use propaganda and disinformation against State institutions as other components of their insurgency doctrine.

    Maoists and Maoism in India

    • The Communist Party of India (Maoist) is a Marxist–Leninist–Maoist banned communist political party and militant organization in India.
    • It aims to overthrow the “semi-colonial and semi-feudal Indian state” through people’s war.

    Confused between Maoists and Naxalities?

    • Usually, people confuse themselves over Maoists and Naxalities and cannot exactly trace the difference between the two terminologies.
    • Media seems to be confused with the terms and uses Maoists and Naxalities quite inter-changeably.
    • This creates confusion in the readers’ minds over the actual meaning of individual terms.

    The actual difference between the terms is as follows:

    • The difference between Maoists struggle and the Naxalite movement is that both trace their origin to the Naxalbari uprising of 1967.
    • But while the Naxalite movement thrives on the original spirit of Naxalbari; the Maoist struggle is an outcome of the 1967 uprising.
    • Maoists work with an agenda and use weapons to achieve their aims.
    • Naxalism focuses on mass organisations while the Maoism relies mainly on arms.

    History and evolution

    • Russian Revolution: Naxalism in India, like any other leftist movement around the globe draws its ideological basis from the Russian revolution.
    • Overthrowing Tsarist Regime: Lenin successfully fought against the Czarist Rule through a combination of peasant movement and an armed struggle.
    • Marxian ideology of class struggle: The prime intent was to bestow power in the hands of the exploited and marginalized and enforce societal control over governance and nation building.
    • Neo-Marxism: After the success of the Lenin-led revolution in Russia, the intellectual class in many countries got inspired. Prominent amongst them were Fidel Castro and Mao Zedong.

    Root cause of origin in India

    • Corporate exploitation: Since Eastern India is rich in natural resources including forests, minerals and mines, tribal face exploitation and harassment from government and corporate bodies targeting to extract those resources.
    • Tribal alienation: Tribal communities have been systematically alienated from their traditional rights over natural resources after independence.
    • Livelihood losses: Tribal livelihood is at stake due to depletion of natural resource base.
    • Forceful displacement: Forceful displacement from their homeland destroys their traditional governance system.
    • Absence of governance: In such exploited areas, the absence of governance becomes a self-fulfilling prophecy since the delivery systems are extinguished through killings and intimidation.
    • Foreign provocations: Many of LWE outfits are supported by external forces inimical to India and the Maoists consider such alliances as strategic assets.

    Other factors:

    1. Oppression and HR violations by Security Forces e.g. AFSPA
    2. Violation of Constitutional Protections under PESA and FRA
    3. Prevalence of Acute Poverty

    Impact of LWE

    • Romanticism without a cause: Some sections of the society, especially the younger generation, have romantic illusions about the Maoists, arising out of an incomplete understanding of their ideology of Class –Struggle.
    • Extreme violence: Their doctrine glorifies violence as the primary means to overwhelm the existing socio-economic and political structures.
    • Destruction of governance mechanism: LWEs aims at creating a vacuum at the grassroots level of the existing governance structures by killing lower-level government officials, police personnel of the local police stations and the people’s representatives of the PRIs.
    • Radicalization of youths: After creating a political and governance vacuum, they coerce the local population to join the movement.
    • Urban-Maoism: Many extremists have facilitated mass-mobilization in semi-urban and urban areas through ostensibly democratic means often led by well-educated intellectuals.

    Outcomes of perpetrating LWE

    The Leftist organizations skilfully use state structures and legal processes to further the Maoist agenda and weaken the enforcement regime through:

    1. Recruitment of ‘professional revolutionaries’
    2. Raising funds for the insurgency
    3. Creating urban shelters for underground cadres
    4. Providing legal assistance to arrested cadres and
    5. Mass- mobilization by agitating over issues of relevance/ convenience

    Govt initiatives for LWE-affected areas

    • Aspirational Districts: The MHA has been tasked with the monitoring of the Aspirational districts programme in 35 LWE affected districts.
    • HRD measures: Building of schools under the Eklavya model.
    • Road Connectivity Project for LWE affected areas (RRP-II): This aims for improving road connectivity in LWE affected States. Under this, 9279 km of roads and 392 bridges are sanctioned.
    • Naxal Surrender Policy: It aims to wean away misguided youth and hardcore naxalites who have strayed into the fold of the naxal movement and cannot find a way back.
    • National Policy Action Plan: To address Left Wing Extremism approved in 2015, has development as one of the most important component.

    SAMADHAN doctrine: It encompasses the entire strategy of government from short-term policy to long-term policy formulated at different levels. SAMADHAN stands for-

    • S- Smart Leadership
    • A- Aggressive Strategy
    • M- Motivation and Training
    • A- Actionable Intelligence
    • D- Dashboard Based KPIs (Key Performance Indicators) and KRAs (Key Result Areas)
    • H- Harnessing Technology
    • A- Action plan for each Theatre
    • N- No access to Financing

    Way forward

    • Indian counterinsurgency has to work with a dual objective of defeating the insurgents militarily and fully quell the insurgent impulses.
    • This will need institutional overhauls.
    • States must do more to synergize their efforts by launching coordinated operations, thereby denying Maoists any space for manoeuvrability.
    • On parallel grounds, it is also important to segregate the population from the insurgents both operationally and ideologically.
    • The conflict over the distribution of resources can be mended with economic development.

  • Draft Telecom Bill 2022

    telecom

    In a bid to do away with British-era laws governing the telecom sector, the Department of Telecommunications (DoT) issued the draft Indian Telecommunication Bill, 2022.

    Indian Telecommunication Bill, 2022

    • The proposed Bill aims to bring in sweeping changes to how the telecom sector is governed, primarily by giving the Centre more powers in several areas to do so.
    • The draft Bill consolidates three separate acts that govern the telecommunications sector:
    1. Indian Telegraph Act 1885
    2. Indian Wireless Telegraphy Act 1933, and
    3. The Telegraph Wires, (Unlawful Protection) Act 1950

    Why has the government issued a draft Telecommunication Bill?

    • Through the bill, the Centre aims to consolidate and amend the existing laws governing the provision, development, expansion and operation of telecom services, networks and infrastructure.

    Key amendments introduced

    • Inclusion of messengers: One of the key changes is inclusion of new-age over-the-top communication services like WhatsApp, Signal and Telegram in the definition of telecommunication services.
    • Licensing of telecom services: As per the draft law, providers of telecom services will be covered under the licensing regime, and will be subjected to similar rules as other telecom operators.
    • Covering OTT services: This issue has been under contention for several years now with telecom service providers seeking a level-playing field with OTT apps over communication services such as voice calls, messages, etc. Operators had to incur high costs of licences and spectrum, while OTT players rode on their infrastructure to offer free services.

    Other focus areas

    • The Centre is also looking to amend the Telecom Regulatory Authority of India Act (TRAI Act) to dilute the sectoral watchdog’s function of being a recommendatory body.
    • The current TRAI Act mandates the telecom department to seek the regulator’s views before issuing a new licence to a service provider.
    • The proposed Bill does away with this provision.
    • It has also removed the provision that empowered TRAI to request the government to furnish information or documents necessary to make this recommendation.
    • Additionally, the new Bill also proposes to remove the provision where if the DoT cannot accept TRAI’s recommendations or needs modification, it had to refer back the recommendation for reconsideration by TRAI.

    Addressing the concerns of telecom industry

    (1) Insolvency of Telecoms

    • The DoT has also proposed that if a telecom entity in possession of spectrum goes through bankruptcy or insolvency, the assigned spectrum will revert to the control of the Centre.
    • So far, in insolvency proceedings, there has been a lack of clarity on whether the spectrum owned by a defaulting operator belongs to the Centre, or whether banks can take control of it.

    (2) Granting relief

    • The draft Bill also accords the Centre powers to defer, convert into equity, write off or grant relief to any licensee under extraordinary circumstances, including financial stress, consumer interest, and maintaining competition, among other things.

    (3) Replacing USOF

    • It also proposes to replace the Universal Service Obligation Fund (USOF) with the Telecommunication Development Fund (TDF).
    • USOF is the pool of funds generated by the 5 per cent Universal Service Levy that is charged upon all telecom fund operators on their Adjusted Gross Revenue.
    • The USOF has largely been used to aid rural connectivity.
    • However, with the TDF, the objective is also to boost connectivity in underserved urban areas, R&D, skill development, etc.

    Back2Basics: Universal Service Obligation Fund (USOF)

    • The Universal Service Obligation Fund (USOF) was formed by an Act of Parliament, was established in April 2002 under the Indian Telegraph (Amendment) Act 2003.
    • It aims to provide financial support for the provision of telecom services in commercially unviable rural and remote areas of the country.
    • It is an attached office of the Department of Telecom, and is headed by the administrator, who is appointed by the central government.

  • New Account Settlement System for Stock Trading

    Beginning October 1, the new account settlement system for the stock broking industry will kick in under the new guidelines issued by the Securities and Exchange Board of India (SEBI).

    What is Settlement of Accounts?

    • The SEBI mandates stockbrokers to settle i.e., transfer the available credit balance from trading account to bank account, at least once in a quarter (90 days) or 30 days.
    • The process of transferring the unutilised funds back into the bank account is called ‘Running Account Settlement’ or ‘Quarterly Settlement of Funds’.
    • The funds are transferred back to the primary bank account of the customer that is linked to the trading account.
    • As per the latest guidelines, the settlement will now be done on the first Friday of the quarter or the month depending upon the option selected by the customer.

    What are SEBI’s new settlement guidelines?

    • On July 27, SEBI issued new guidelines on running accounts of client funds and securities lying with the broker.
    • As per the new guidelines, with effect from October 1, 2022, the settlement of running account of clients’ funds will be done by the trading members after considering the end of the day (EOD) obligation of funds.
    • In cases where the client has opted for a monthly settlement process, then the running account shall be settled on the first Friday of every month.

    How will it impact investors and traders?

    • Changes in settlement brought in by SEBI over the last few years have had the aim of protecting the investor and preventing the misuse as money lying in trading accounts of investors for long periods.
    • SEBI’s move will give certainty to investors and trading members.
    • It will help brokers develop a system just like banks, which credit interest in the accounts of their customers at the end of the quarter.
    • Another advantage would be that if a customer has more than one demat account with different brokers, having one settlement date for the entire industry will make it easier for her to keep track of her funds.

    Back2Basics: Securities and Exchange Board of India (SEBI)

    • The SEBI is the regulatory body for securities and commodity market in India under the jurisdiction of Ministry of Finance Government of India.
    • It was established on 12 April 1988 and given Statutory Powers on 30 January 1992 through the SEBI Act, 1992.

    Jurisdiction of SEBI

    • SEBI has to be responsive to the needs of three groups, which constitute the market:
    1. Issuers of securities
    2. Investors
    3. Market intermediaries

    SEBI has three powers rolled into one body: quasi-legislative, quasi-judicial and quasi-executive.

    • It drafts regulations in its legislative capacity, it conducts investigation and enforcement action in its executive function and it passes rulings and orders in its judicial capacity.
    • Though this makes it very powerful, there is an appeal process to create accountability.
    • There is a Securities Appellate Tribunal which is a three-member tribunal and is currently headed by Justice Tarun Agarwala, former Chief Justice of the Meghalaya High Court.
    • A second appeal lies directly to the Supreme Court.

  • NASA’s DART mission prepares for an asteroid Dimorphos collision

    dart

    In the first-of-its kind NASA’s DART Mission is about to hit a small, harmless asteroid millions of miles away.

    What is DART Mission?

    • The main aim of the mission is to test the newly developed technology that would allow a spacecraft to crash into an asteroid and change its course.
    • It is a suicide mission and the spacecraft will be completely destroyed.
    • The target of the spacecraft is a small moonlet called Dimorphos (Greek for “two forms”).
    • It is about 160-metre in diameter and the spacecraft is expected to collide when it is 11 million kilometres away from Earth.
    • Dimorphos orbits a larger asteroid named Didymos (Greek for “twin”) which has a diameter of 780 metres.

    Why Dimorphos?

    • Didymos is a perfect system for the test mission because it is an eclipsing binary which means it has a moonlet that regularly orbits the asteroid.
    • It is observable when it passes in front of the main asteroid.
    • Earth-based telescopes can study this variation in brightness to understand how long it takes Dimorphos to orbit Didymos.

    Collision course

    • At the time of impact, Didymos and Dimorphos will be relatively close to Earth – within 6.8 million miles (11 million kilometers).
    • The spacecraft will accelerate at about 24,140 kilometers per hour when it collides with Dimorphos.
    • It aims to crash into Dimorphos to change the asteroid’s motion in space.
    • This collision will be recorded by LICIACube, or Light Italian CubeSat for Imaging of Asteroids, a companion cube satellite provided by the Italian Space Agency.
    • Three minutes after impact, the CubeSat will fly by Dimorphos to capture images and video.

    Why such mission?

    • Dimorphos was chosen for this mission because its size is relative to asteroids that could pose a threat to Earth.
    • The spacecraft is about 100 times smaller than Dimorphos, so it won’t obliterate the asteroid.
    • The fast impact will only change Dimorphos’ speed as it orbits Didymos by 1%, which doesn’t sound like a lot — but it will change the moon’s orbital period.

  • Dvorak Technique of Weather Forecasting

    Recently, the American meteorologist Vernon Dvorak passed away at the age of 100 who pioneered the widely used Dvorak Technique.

    Who was Vernon Dvorak?

    • Dvorak was an American meteorologist best credited for developing the Dvorak (read as Do-rak) technique in the early 1970s.
    • The technique helps forecast the tropical storm.
    • His technique has saved the lives of millions of people across the world and will continue to do so.

    What is the Dvorak technique?

    • The Dvorak technique was first developed in 1969 and tested for observing storms in the northwest Pacific Ocean.
    • Forecasters used the available satellite images obtained from polar orbiting satellites to examine the features of the developing tropical storms (hurricanes, cyclones and typhoons).
    • During day time, images in the visible spectrum were used while at night, the ocean would be observed using infrared images.
    • It was a cloud pattern recognition technique based on a concept model of the development and decay of the tropical cyclone.

    Why is technique still widely in use?

    • Unlike land, ocean observations in the 1970s were sparse.
    • Today, there continues to be an improved network of land-based meteorological observations, either in the form of taking manual observations, installing automatic weather stations or automatic rain gauges.
    • On the other hand, ocean observations still remain limited.
    • There are many vast regions across the four oceans that have not been fully examined with meteorological instruments.
    • Ocean observations are mostly taken by deploying buoys or dedicated ships, but the number of observations from the seas is still not sufficient across the world.
    • That is why meteorologists have had to depend more on satellite-based imageries, and combine it with the available ocean-data at the time of forecasting the intensity and wind speed of the tropical cyclones.

  • Fly ash generation and Disposal

    fly ashContext

    • India depends heavily on coal for power generation. This creates the problem of fly-ash generation and its proper disposal, usage.
    • The National Green Tribunal (NGT) noted September 19, 2022 that there was an urgent need to augment the utilisation and disposal of fly ash in Chhattisgarh.

    What is fly ash?

    • Fly ash is a by-product of coal combustion. It contains Aluminium Silicate, SiO2, CaO, oxides of iron, magnesium and toxic metals like lead, arsenic, cobalt, and copper.
    • It can travel to far places. India is growing to double its power generation in the next decade and with coal being the biggest source of fuel for power generation, the problem of fly ash is going to increase too.

    fly ash Environmental Problems with fly ash

    • A large quantity of fly ash dumped into poorly designed and maintained ash ponds. About a billion tonnes of this toxic ash lie dumped in these ponds, polluting land, air, and water.
    • All the heavy metals found in fly ash—nickel, cadmium, arsenic, chromium, lead, etc—are toxic in nature. They leech into the surrounding soil and can enter food-chains.
    • Fly ash gets easily ingested through respiration, which causes many diseases such as asthma, neurological disorders.
    • Suspended fly ash in the air acts as a global warming agent and heats the earth’s surface.
    • Fly ash settles on leaves and crops and reduces crop productivity.
    • It pollutes the groundwater.
    • There is a reduction in recharging of groundwater due to fly ash filled mine voids.
    • Reduces visibility by creating dense fog in the winter season.

    fly ashIssues with fly ash management

    • The government mandates that all coal power plants (CPPs) reach 100% utilization of fly ash.
    • Along with it, CPPs should give a certain amount of fly ash free of cost for MSMEs to manufacture bricks, tiles and rest of the fly ash should be sold to other industries.
    • CPPs will have to maintain fly ash ponds to reduce its suspension in air.
    • But all these steps for utilization areas are problematic as they do little to mitigate these risks.
    • The pricing of fly ash is increasingly becoming a contentious issue that is hampering its gainful utilization.
    • The current approaches to evaluating risks with fly ash disposal are very limited, and they may underestimate the true risks
    • In spite of initiatives taken by the government, several nongovernmental and research and development organizations for fly ash utilization, the level of fly ash utilization in the country is quite low at only 38% which is less than the global standards.
    • Hence, rather than being utilized, fly ash is being stored despite warnings from regulators.
    • Deposition in storage places has negative influences on water and soil because of their mineral composition as well as morphology and filtration properties.
    • Ash-handling units are the biggest consumers of water in CPPs. The government advocates the designed ash-to-water ratios as approximately 1:5 for fly ash, but the observed ratios have been around 1:20.
    • Certain states have discouraged the use of blended cement and fly ash bricks in public works.

    fly ashThe above issues can be addressed by

    • Greater regulatory oversight and price control,
    • Revision of cement blending standards,
    • Research in improving fly ash quality,
    • Reducing the cost of transportation,
    • Provisions for overcoming information asymmetries,
    • Incentivising use in brick kilns for producing fly ash bricks,
    • Overall sensitization of key decision-makers on the matter.
    • Instead of dumping it on ash ponds, can be used for construction due to its reuse as pozzolan, and replacement of portland cement by hydraulic cement
    • Due to its grain size distribution, enhanced strength permeability, it can be used to construct embankments at road construction, concrete dams like GHATGHAR DAM
    • Strong penalties for those production units who do not use proper filtration devices
    • Moving to renewable energy production away from coal-based thermal production.

    Conclusion

    • Utilization of Fly Ash is not only possible but also essential. In this context “Fly Ash Mission of Government of India” is a slow but steady start, the pace of which needs to be ramped up. An honest effort is required by the concerned stakeholders to improve the perceptions of fly ash-based cement or concrete; increase its use, particularly for government works; and impart scientific knowledge about fly ash, its uses, and possible impacts.

  • Government approves 50% incentive of project cost for setting up Semiconductor Units

    The Union Cabinet has approved a uniform incentive of 50% of the project cost for setting up semiconductor, display and compound semiconductor fabrication units.

    Why in news?

    incentive

    • Maharashtra is witnessing a political firestorm.
    • The Vedanta Limited shifted its decision to set up a $20 billion Vedanta-Foxconn semiconductor manufacturing facility in neighbouring Gujarat, despite finalising its location near Pune (Mh).
    • Foxconn is a major chip supplier to Apple. It has suspended its operations in the Chinese tech hub of Shenzhen and is now shifting to India.
    • Bigger companies, such as Intel, TSMC, Samsung, etc., have announced such plans.

    Spats between states over the location of critical industries display the grim picture of competitive bidding in India. This portrays India’s negative image as against ease of doing business.

    About the Incentive Scheme

    • The scheme has been named the “Programme for Development of Semiconductors and Display Manufacturing Ecosystem.”
    • Previously, the three schemes had an incentive range of 30-50%.
    • While incentives for setting up semiconductor fabrication were based on the size of the chip, for display fabrication and compound semiconductor fabs, the incentives were largely 30% of the total cost of the project.
    • This scheme aims to project India’s position as global hub for electronics manufacturing with semiconductors as the foundational building block.

    Why need such an incentive?

    • Huge Investments involved: Semiconductor Fabrication facility requires many expensive devices to function. Complex tools and equipment are required to test quality and move silicon from location to location within the ultra-clean confines of the plant.
    • Economy of scale:   In semiconductor fabrication, a high volume production is required to be maintain so as to meet the increasing demand of the marketplace, at the same time, a strong financial backing as Indian market is very much uncertain about financial fluctuations.
    • Requirement highly skilled labour:   Semiconductor fabrication is a multiple-step sequence of photolithographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconducting material. This actually requires high skills.
    • Scarcity of raw materials: From a value-chain perspective, it needs silicon, Germanium & Gallium arsenide and Silicon carbide which are not available in India and needs to be imported.
    • Uncertain Indian market: A semiconductor fabrication facility in India cannot independently rely on Indian customers for their entire sales structure. They have to maintain overseas customer base to balance inflections from Indian market due to market trends, government policies etc.
    • Disposal of hazardous waste: Many toxic materials are used in the fabrication process such as arsenic, antimony, and phosphorus. Hazardous impact on the environment by the industry may act as an impediment to India’s commitment to mitigate climate change.

    Other supportive initiatives in India

    • India Semiconductor Mission (ISM): It was announced with the aim to attract large-scale investments for manufacturing facilities in the midst of a global chip crisis.
    • Make in India: This aims to transform India into a global hub for Electronic System Design and Manufacturing (ESDM).
    • PLI scheme: In December 2021 the Centre sanctioned ₹76,000 crore under the production-linked incentive (PLI) scheme to encourage the manufacturing of various semiconductor goods within India.
    • DLI scheme: It offers financial incentives, design infrastructure support across various stages of development and deployment of semiconductor design for Integrated Circuits (ICs), Chipsets, System on Chips (SoCs), Systems & IP Cores and semiconductor linked design.
    • Digital RISC-V (DIR-V) program: It intends to enable the production of microprocessors in India in the upcoming days achieving industry-grade silicon and design wins by December 2023.
    • India Semiconductor Mission (ISM): The vision is to build a vibrant semiconductor and display design and innovation ecosystem to enable India’s emergence as a global hub for electronics manufacturing and design

    Way forward

    • Policy framework: As foundry setup is highly Capital intensive, it must be supported with a solid long term plan and financial backing. This backing is required from the entrepreneur & the government both.
    • Fiscal sustenance: In text of Indian Government as tax holiday, subsidy, zero duty, financial investment etc. will play an important role in promoting the Fab along with the semiconductor industry in India; this will put further pressure on already large Fiscal Deficit.
    • Support Infrastructure: World class, sustainable infrastructure, as required by a modern Fab be provided, with swift transportation, large quantity of pure water, uninterrupted electricity, communication, pollutant free environment etc.
