    Starting with our list of deadly mistakes you should avoid.

    1. Ignoring or failing to understand what UPSC expects from you.

    UPSC through this exam has to maintain the merit in the Indian administration. For that, they are constantly evolving w.r.t. the exam process – questions and the manner in which they ask questions. Just go through the last three years’ UPSC Prelims question papers and you will realize it yourself.

    Just knowing the syllabus and sources is not enough. Neither is it about finishing the syllabus only. It has to be done in a certain manner. Only when you know what UPSC wants you can make an effort in that direction. Fill Samanvaya form below to discuss the expectations of UPSC and more.

    2. Not having a workable strategy

    Internet and youtube are flooded with IAS toppers’ strategy. While it worked for the toppers, what will work for you is a strategy that is based on your situation (UPSC experience, education, background, etc.), your learning style, the time you have, consideration for your job commitments, etc.

    In short, your strategy has to be unique. Just for you. Moreover, it has to be organic and adaptable. Else it won’t work. Let us help make one for you or improve your strategy. (Just fill in the Samanvaya form)

    3. No mechanism to identify your mistakes

    Even if you’ve taken multiple attempts you are bound to make some mistakes, much more for UPSC beginners. These are inevitable. And this makes it essential for you to put up a mechanism to find out and highlight those mistakes in your preparation on a regular basis.

    Eg. Finished Modern History (or any subject), only to realize after a month that you don’t seem to remember a thing or solve a UPSC level MCQ. This realization that you’re doing it wrong should have come to you on the first or second day itself. You could’ve saved your precious time, efforts and attempt.

    Discussing your approach with mentors is one of them. Don’t have a mentor? Yes, you have one at Civilsdaily. Fill in this Samanvaya form.

    Civilsdaily’s Hall of Fame.

    4. Inability to rectify your mistakes

    Maybe due to inertia or ignorance or fear of change, most of the aspirants are not able to rectify their mistakes.

    Eg. Even after finishing Laxmikant for Polity a couple of times you can’t understand why you are scoring miserably low marks in Polity pre-mocks. Or, not able to improve your mains answers.

    Only those who are able to rectify their mistakes on a frequent basis are able to clear this exam. What issues with your preparation you feel are difficult to resolve? Fill Samanvaya and let us help you resolve them.

    5. Integrate these learnings in your preparation

    After you have developed the awareness of the mistakes and what should be done, you must integrate it asap with your preparation. The required unlearning and re-learning must take on a regular basis.

    Eg. You were scoring less in answer writing and realized that it was due to either missing out on the demand of the question or not giving examples to support your arguments. Don’t stall the process of improvement. Do it asap.

    Instead of regressing or stopping, you should always be moving forward, closing the loops of progress, and returning to the most effective path.

    Whatever be the stage of your IAS exam preparation, these mistakes must be avoided at all costs and nipped-in-the-bud.

    More than 10.5 lakh applied, but only 796 are going to clear UPSC IAS 2020. It is going to be much more challenging in 2021 and 2022.

    It is not just about walking. It is about walking in the right direction. If you don’t have these above issues sorted you are bound to make more mistakes.

    Fill the Samanvaya form given above to discuss your strategy and issues that you are facing.

    Why mentorship?

    See, broadly six factors determine your success in cracking this prestigious IAS exam and the most important being understanding the expectations of UPSC and according to that planning and strategizing; other being, Learning – Knowledge and information; Analyzing – making linkages, connections, etc.; Executing and utilizing information; and Constant course correction – because mistakes are inevitable, need to rectify them asap.

    These are the areas where most of the aspirants fail to create a balance. Where are you facing an issue?

    Integrate them in your preparation. We’ll tell you how to do it

  • Need for national security shield in FDI

     

    Relaxation on Chinese FDI

    • Last April, India had subjected all Chinese FDI to mandatory government screening.
    • The aim was to curb opportunistic takeovers of Indian companies, a concern fuelled by sharp corrections in equity markets in March 2020.
    • Several economies including the US, Australia, Canada and Germany faced similar concerns.
    • They blocked specific takeover attempts, using special laws for national security screening of inward FDI.
    •  In the absence of similar legislation, India did not differentiate between investments which raised genuine national security concerns and those that did not.
    • This is a crucial shortcoming.
    • With market indices now hovering at their peaks, reportedly India may allow Chinese FDI up to 25 per cent in equity under the automatic route.

    Regulation of FDI and issues with it

    • India regulates foreign investments primarily through FEMA.
    • FEMA clearly provides two specific macro-prudential objectives — facilitating external trade and payments; and promoting orderly development and maintenance of foreign exchange markets in India.
    • Accordingly, it empowers the central government and the RBI, acting in consultation with each other, to regulate capital account transactions.
    • These regulations determine who can invest through the FDI route, in which sector and how much.
    • In practice, however, FEMA regulations have often responded to concerns not strictly related to macro-prudential objectives.
    • One such concern has been national security.

    Need for the law to scrutinise FDI from national security angle

    • Shortcoming of FEMA underscores the need for India to emulates its western peers and enact a statute specifically designed for national security screening of strategic FDI.
    • Unlike FEMA, this new statute must explicitly lay down legal principles for determining when a foreign acquisition of an Indian company poses genuine national security threats.
    • In this regard, a policy paper published by the Peterson Institute for International Economics three types of legitimate threats from foreign acquisitions.

    3 Types of threat from foreign acquisitions

    1) Dependency on foreign supplier

    • The first threat arises if a foreign acquisition renders India dependent on a foreign-controlled supplier of goods or services crucial to the functioning of the Indian economy.
    • For this threat to be credible, it needs to be further established that the industry in which the acquisition is supposed to take place is tightly concentrated, the number of close substitutes limited, and the switching costs are high.

    2) Technology transfer

    • The second threat emanates from a proposed acquisition transferring a technology or an expertise to a foreign-controlled entity that might be deployed by that entity or a foreign government in a manner harmful to India’s national interests.
    • The credibility of this threat again depends on whether the market for such technology or expertise is tightly concentrated or if they are readily available elsewhere.

    3) Threat of infiltration, surveillance or sabotage

    • The third threat arises if a proposed acquisition allows insertion of some potential capability for infiltration, surveillance or sabotage via human or non-human agents into the provision of goods or services crucial to the functioning of Indian economy.
    • This threat is particularly credible when the target company supplies crucial goods or services to the Indian government, its military or even critical infrastructure units and the switching costs are high.

    Way forward

    • The above stated 3 types of threats could provide conceptual clarity in the new statute could make national security assessments objective, transparent and amenable to the rule of law.
    • On procedure, the statute must empower only the finance minister to reject certain strategic foreign acquisitions on national security grounds.
    • Both the power and accountability mechanisms should be hardcoded into the statute itself, as is the case in some mature parliamentary democracies.
    • For instance, the Australian Foreign Acquisitions and Takeovers Act, 1975 empowers the treasurer to block certain foreign acquisitions on national security grounds.
    • Similarly, the Investment Canada Act, 1985 empowers a minister to reject certain foreign acquisitions.

    Consider the question “India needs to recognise the national security threat emanating from strategic FDI. This requires identifying threats. In lights of this, examine the types of threats and suggest the ways to deal with it.” 

    Conclusion

    Overall, India’s tryst with Chinese FDI underscores the importance of identifying specific national security threats emanating from strategic FDI and addressing them objectively. This is too sensitive a matter to be left to capital controls under FEMA. A dedicated statute for national security screening of inward FDI would be best suited for handling such issues.

  • Factors driving India’s growing security footprints in West Asia

    The article examines the factors that are leading to a growing footprint of Asian economies in West Asia.

    Growing interest of Asian Economies  in West Asia

    • This month, a contingent of the Indian Air Force participated in a multi-nation exercise hosted by the United Arab Emirates (UAE) named Desert Flag (March 3-27).
    • Other than India and the UAE, Bahrain, France, Saudi Arabia, South Korea and the United States are also participating.
    • While joint exercises in West Asia between Arab states and their western counterparts is common, the 2021 edition’s involvement of contingents from India and South Korea.
    • This showcases the growing interests of Asian economies.
    • As net importers of crude oil, these Asian economies rely heavily on the West Asian states for their supplies,
    • And, by association, Asian economies have increased stakes in the safety and security of the region from the perspective of political and economic stability.
    • And more importantly, in the protection of vital sea lanes in areas such as the Strait of Hormuz, the Gulf of Aden and the Red Sea stretching out into the Arabian Sea and the wider Indian Ocean.

    Declining U.S. influence

    • In April 2020, Saudi Arabia was India’s top supplier of oil followed by Iraq.
    • For South Korea, in late 2019, it was also Saudi Arabia as the top supplier.
    • The participation of both India and South Korea in these exercises in the Persian Gulf is reflective of these trends and growing concerns in Asian capitals over an eroding U.S. security blanket in the region.

    Tension in Iran-U.S. relations

    • Both India and South Korea have found themselves caught in regional tensions as the pressure on Iran to restart the 2015 nuclear agreement (Joint Comprehensive Plan of Action, or JCPOA) increases.
    • Both India and South Korea have faced carbon-copy consequences over the past decade as the West first negotiated with Iran, and later tried to manage the fallout of the JCPOA collapse.

    India’s role in protecting it’s energy interests

    • The idea of Asian nations having to band together to protect their energy interests in West Asia is not new.
    • Former Indian diplomats have even suggested an idea equitable to an ‘importers OPEC’ led by Asian states which today have a much larger stake in West Asia’s oil than the West.
    • The Indian Navy has made multiple port calls from the UAE and Kuwait to Iran and Qatar in recent years.
    • In 2020, India had also planned its first bilateral naval exercise with Saudi Arabia.

    Consider the question “Examine the factors responsible for India’s growing security footprint in West Asia and how India is achieving its objectives?”

    Conclusion

    Regional states will become more responsible for their own security, and as Asian economies become stronger stakeholders, their geopolitics will become more visible across this geography.

  • Bureaucrats cannot be State Election Commissioners: SC

    The Supreme Court gas held that independent persons and not bureaucrats should be appointed State Election Commissioners.

    No bureaucrats in SEC

    • The judgment came on an appeal against an order of the Bombay High Court which had set aside the election notification issued by the Goa State Election Commission in some municipalities.
    • Justice F. Nariman, in a judgment, said giving government employees the additional charge of State Election Commissioners is a “mockery of the Constitution”.
    • It said government employees holding the post of State Election Commissioners as additional charge should give up the post.
    • The Supreme Court said its direction should be followed strictly.

    Why such a move?

    • Under the constitutional mandate, it is the duty of the State to not interfere with the functioning of the State Election Commission.
    • The independence of Election Commissions cannot be compromised at any cost, the Bench said.

    State Election Commission

    • Under the 73rd and 74th constitutional amendment acts, State Election Commissions were created for every state to conduct elections to panchayats and municipalities.
    • The SECs came into as envisaged in Articles 243K and 243ZA of the Constitution of India.
    • The above Articles provide that the superintendence, direction and control of the preparation of electoral rolls for, and the Conduct of all elections to the Panchayats and Municipalities shall vest in the SEC.
    • The Constitution itself has facilitated provision for smooth, free and fair, regular elections to the Local bodies and has, therefore, entrusted the SEC with the responsibility for holding such elections.
    • In the domain of the elections to the local bodies, the SEC functions independently and has the same powers and duties as that of the Election Commission of India.

    Back2Basics: Election Commission of India (ECI)

    • The body administers elections to the Lok Sabha, Rajya Sabha, State Legislative Assemblies, State Legislative Councils and the offices of the President and Vice President of the country.
    • The EC operates under the authority of the Constitution per Article 324 and subsequently enacted the Representation of the People Act.
    • The commission has the powers under the Constitution, to act in an appropriate manner when the enacted laws make insufficient provisions to deal with a given situation in the conduct of an election.
    • Being a constitutional authority, EC is amongst the few institutions which function with both autonomy and freedom, along with the country’s higher judiciary, the UPSC and the CAG.
  • Places of Worship Act, 1991

    The Supreme Court has asked the Centre to respond to a plea challenging the Places of Worship (Special Provisions) Act, 1991. The court has opened the doors for litigation in various places of worship across the country including Mathura and Varanasi.

    Take this ‘wonderful’ question from CS Mains 2019:

    Q.What are the challenges to our cultural practices in the name of secularism?

    Places of Worship Act, 1991

    • It was passed in 1991 by the P V Narasimha Rao-led government.
    • The law seeks to maintain the “religious character” of places of worship as it was in 1947 — except in the case of the Ram Janmabhoomi-Babri Masjid dispute, which was already in court.
    • The law was brought in at the peak of the Ram Mandir movement, exactly a year before the demolition of the Babri Masjid.
    • Introducing the law, then Home Minister S B Chavan said in Parliament that it was adopted to curb communal tension.

    What are its provisions?

    The objective of the law describes it as an Act to prohibit conversion of any place of worship.

    • It aims to provide for the maintenance of the religious character of any place of worship as it existed on the 15th day of August 1947, and for matters connected therewith or incidental thereto”.
    • Sections 3 and 4 of the Act declared that the religious character of a place of worship shall continue to be the same as it was on August 15, 1947.
    • No person shall convert any place of worship of any religious denomination into one of a different denomination or section.
    • Section 4(2) says that all suits, appeals or others regarding converting the character of a place of worship, that was pending on August 15, 1947, will stand abated when the Act commences and no fresh proceedings can be filed.
    • However, legal proceedings can be initiated after the commencement of the Act if the change of status took place after the cut-off date of August 15, 1947.

    What does it say about Ayodhya, and what else is exempted?

    • Act does not to apply to Ram Janma Bhumi Babri Masjid.

    Besides the Ayodhya dispute, the Act also exempted:

    • any place of worship that is an ancient and historical monument or an archaeological site, or is covered by the Ancient Monuments and Archaeological Sites and Remains Act, 1958;
    • a suit that has been finally settled or disposed of;
    • any dispute that has been settled by the parties or conversion of any place that took place by acquiescence before the Act commenced.

    What has the Supreme Court said about the Act?

    • In the 2019 Ayodhya verdict, the Constitution Bench led by former CJI Ranjan Gogoi referred to the law and said it manifests the secular values of the Constitution and strictly prohibits retrogression.
    • In providing a guarantee for the preservation of the religious character of places, Parliament determined that independence from colonial rule furnishes a constitutional basis for healing the injustices of the past.
    • The law addresses itself to the State as much as to every citizen of the nation. Its norms bind those who govern the affairs of the nation at every level.
    • Those norms implement the Fundamental Duties under Article 51A and are hence positive mandates to every citizen as well.

    Why is the law under challenge?

    • A politician has challenged the law on the ground that violates secularism.
    • He has also argued that the cut-off date of August 15, 1947, is “arbitrary, irrational and retrospective” and prohibits Hindus, Jains, Buddhists, and Sikhs from approaching courts to “reclaim” their places of worship.
    • Such places, he argued, were “invaded” and “encroached” upon by “fundamentalist barbaric invaders”.
    • The right-wing politicians have opposed the law even when it was introduced, arguing that the Centre has no power to legislate on “pilgrimages” or “burial grounds” which is under the state list.
    • Another criticism against the law is that the cut-off is the date of Independence, which means that the status quo determined by a colonial power is considered final.
  • Curbing Benzene Emission

    A joint committee appointed by the National Green Tribunal (NGT) to study air pollution in Kerala has pointed out that petrol refuelling stations were a major source of benzene emissions and volatile organic compounds (VOCs).

    Why such a move?

    • Benzene is a major constituent of evaporative emission due to its high volatility.

    Try this PYQ:

    Q.Consider the following:

    1. Carbon monoxide
    2. Methane
    3. Ozone
    4. Sulphur dioxide

    Which of the above are released into atmosphere due to the burning of crop/biomass residue?

    (a) 1 and 2 only

    (b) 2, 3 and 4 only

    (c) 1 and 4 only

    (d) 1, 2, 3 and 4

    What is Benzene?

    • Benzene is a chemical that is a colourless or light yellow liquid at room temperature. It has a sweet odour and is highly flammable.
    • It evaporates into the air very quickly. Its vapour is heavier than air and may sink into low-lying areas.
    • It dissolves only slightly in water and will float on top of the water.

    Its formation and uses

    Benzene is formed from both natural processes and human activities.

    • Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke.
    • Some industries use benzene to make other chemicals that are used to make plastics, resins, and nylon and synthetic fibres.
    • It is also used to make some types of lubricants, rubbers, dyes, detergents, drugs, and pesticides.

    Benzene emission

    • The major sources of benzene exposure are tobacco smoke, automobile service stations, exhaust from motor vehicles, and industrial emissions.
    • Benzene is present in both exhaust and evaporative emissions. Motor vehicles account for approximately 85% of the total benzene emissions.
    • However, ingestion and dermal absorption of benzene can also occur through contact with contaminated water.

    (d) None of the above can be cited as evidence.

    2001 FO32

    • There is no threat of a collision with our planet now or for centuries to come.
    • Scientists know its orbital path around the Sun very accurately since it was discovered 20 years ago and has been tracked ever since.
    • It won’t come closer than 2 million km to Earth, but it will present a valuable scientific opportunity for astronomers who can get a good look at a rocky relic that formed at the dawn of our Solar System.

    Proximity to Earth

    • For comparison, when it is at its closest, the distance of 2 million km is equal to 5¼ times the distance from Earth to the Moon.
    • Still, that distance is close in astronomical terms, which is why 2001 FO32 has been designated a “potentially hazardous asteroid”.
    • The reason for the asteroid’s unusually speedy close approach is its highly eccentric orbit around the Sun, an orbit that is tilted 39° to Earth’s orbital plane.
    • This orbit takes the asteroid closer to the Sun than Mercury, and twice as far from the Sun as Mars.
    • Later, the asteroid slows after being flung back out into deep space and swinging back toward the Sun. It completes one orbit every 810 days (about 2¼ years).

    Studying the visitor

    • This asteroid will provide an opportunity for astronomers to get a more precise understanding of the asteroid’s size and albedo (i.e. how bright, or reflective, its surface is), and a rough idea of its composition.
    • When sunlight hits an asteroid’s surface, minerals in the rock absorb some wavelengths while reflecting others.
    • By studying the spectrum of light reflecting off the surface, astronomers can measure the chemical “fingerprints” of the minerals on the surface of the asteroid.
  • Seabuckthorn plantations in Himachal Pradesh

    The Himachal Pradesh government has decided to start planting Seabuckthorn in the cold desert areas.

    What is Seabuckthorn?

    • It’s a shrub that produces an orange-yellow coloured edible berry.
    • In India, it is found above the tree line in the Himalayan region, generally in dry areas such as the cold deserts of Ladakh and Spiti.
    • In Himachal Pradesh, it is locally called Himalayan chharma and grows in the wild in Lahaul and Spiti and parts of Kinnaur.
    • According to the Seabuckthorn Association of India, around 15,000 hectares in Himachal, Ladakh, Uttarakhand, Sikkim and Arunachal Pradesh are covered by this plant.

    Q.Recently, there was a growing awareness in our country about the importance of Himalayan nettle (Girardinia diversifolia) because it is found to be a sustainable source of

    (a) anti-malarial drug

    (b) biodiesel

    (c) pulp for paper industry

    (d) textile fibre

    Benefits of the Seabuckthorn plant

    (1) Medicinal benefits

    • As a folk medicine, Seabuckthorn has been widely used for treating stomach, heart and skin problems.
    • In the last few decades, scientific research worldwide has backed many of its traditional uses.
    • Its fruit and leaves are rich in vitamins, carotenoids and omega fatty acids, among other substances, and it can help troops in acclimatizing to high-altitude.

    (2) Ecological benefits

    • Besides being an important source of fuelwood and fodder, Seabuckthorn is a soil-binding plant that prevents soil-erosion, checks siltation in rivers and helps preserve floral biodiversity.
    • In the Lahaul valley, where willow trees are dying in large numbers due to pest attack, this hardy shrub is a good alternative for protecting the local ecology.

    (3) Commercial benefits

    • Seabuckthorn also has commercial value, as it is used in making juices, jams, nutritional capsules etc.
    • But wild Seabuckthorn cannot sustainably supply raw material to the industry, and the plant needs to be cultivated on a large scale as is being done in China.

    What is the latest project?

    • The Seabuckthorn association wants the forest departments of various Himalayan states/UTs to plant Seabuckthorn on arid and marginal lands using compensatory afforestation or CAMPA funds.
    • Recently, the union ministry of environment, forest and climate change asked these states to submit proposals for taking up such plantations.
    • This is in the light of reduced water flow from Himalayan glaciers and their impact on ecology.
