    What is Post-Disaster Needs Assessment (PDNA)?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: PDNA

    Mains level: Not Much

    pdna

    Post-Disaster Needs Assessment (PDNA) is now being done simultaneously in Assam, Himachal Pradesh, Gujarat, Karnataka, Jharkhand, Maharashtra, Odisha and Meghalaya.

    Why in news?

    • PDNA is now being used to evaluate the financial and social cost of local disasters in eight states in India.
    • These states all experienced severe flooding in the last few months.
    • The results of these assessments are likely to come out next month.

    What is PDNA?

    • PDNA is an internationally accepted methodology for determining the physical damages, economic losses, and costs of meeting recovery needs after a natural disaster through a government-led process.
    • It is an international framework for assessing losses and damages in the aftermath of a disaster.
    • The framework helps get recovery and reconstruction efforts right following a disaster.
    • Globally, of the 55 PDNAs conducted worldwide since 2008, only two droughts — one in Malawi and the other Marshall Islands in 2016 — were of slow-onset disasters.

    Components of PDNA

    • PDNA includes a calculation of the disaster’s impact on Gross Domestic Product, the balance of payment and fiscal budget.
    • Secondly, how this affects the flow of revenue to multiple sectors is evaluated.
    • For example, the number of farmers’ income affected per damaged acre of land and the livelihoods lost.
    • Overall, a quantitative assessment is additionally done on the social and environmental impact of the disaster.

    History of PDNA in India

    • This is not the first time PDNA has been conducted in India.
    • It was first adopted during the Kerala floods of 2018 and again during the cyclone in Odisha in 2019, both unprecedented disasters.
    • Until now, the assessment was only limited to massive disasters that required international funding from the World Bank, the Asian Development Bank and the United Nations.

    15th Finance Commission provision

    • The 15th finance commission report of 2021, for the first time, made a provision for recovery and reconstruction in the national disaster management budget, which is at the core of the PDNA.
    • The states did not receive international funding to do the current ongoing PDNAs, as they are expected to take the money from the budget.

  • Global Geological And Climatic Events

    What are Eclipses?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Eclipses

    Mains level: Read the attached story

    eclipse

    India recently witnessed a partial solar eclipse. Let’s take a look over all dynamics of Eclipses.

    What are Eclipses?

    • An eclipse takes place when one heavenly body such as a moon or planet moves into the shadow of another heavenly body.
    • There are two types of eclipses on Earth: an eclipse of the Moon and an eclipse of the Sun.

    [I] A Lunar Eclipse

    eclipse

    • The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon.
    • When this happens, Earth blocks the sunlight that normally is reflected by the moon. (This sunlight is what causes the moon to shine.)
    • Instead of light hitting the moon’s surface, Earth’s shadow falls on it. This is an eclipse of the moon — a lunar eclipse.
    • A lunar eclipse can occur only when the moon is full. (But not every full moon is also a lunar eclipse. Can you guess why?)

    Observing a Lunar Eclipse

    • A lunar eclipse can be seen from Earth at night.
    • A lunar eclipse usually lasts for a few hours.
    • At least two partial lunar eclipses happen every year, but total lunar eclipses are rare.

    There are two types of lunar eclipses: total lunar eclipses and partial lunar eclipses.

    • A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth’s shadow, some sunlight reaches the moon.  The sunlight passes through Earth’s atmosphere, which causes Earth’s atmosphere to filter out most of the blue light. This makes the moon appear red to people on Earth.
    • A partial lunar eclipse happens when only a part of the moon enters Earth’s shadow. In a partial eclipse, Earth’s shadow appears very dark on the side of the moon facing Earth. What people see from Earth during a partial lunar eclipse depends on how the sun, Earth and moon are lined up.
    • In a penumbral lunar eclipse, only the more diffuse outer shadow of Earth – the penumbra – falls on the moon’s face. This third kind of lunar eclipse is much more subtle, and much more difficult to observe than either a total or partial eclipse of the moon.

    [II] A Solar Eclipse

    eclipse

    • Sometimes when the moon orbits Earth, it moves between the sun and Earth.
    • When this happens, the moon blocks the light of the sun from reaching Earth.
    • This causes an eclipse of the sun or solar eclipse.
    • During a solar eclipse, the moon casts a shadow onto Earth.

    There are three types of solar eclipses.

    The first is a Total Solar Eclipse

    • A total solar eclipse is only visible from a small area on Earth.
    • The people who see the total eclipse are in the centre of the moon’s shadow when it hits Earth.
    • The sky becomes very dark as if it were night. For a total eclipse to take place, the sun, moon and Earth must be in a direct line.

    The second type is a Partial Solar Eclipse

    • This happens when the sun, moon and Earth are not exactly lined up.
    • The sun appears to have a dark shadow on only a small part of its surface.

    The third type is an Annular Solar Eclipse

    • An annular eclipse happens when the moon is farthest from Earth. Because the moon is farther away from Earth, it seems smaller. It does not block the entire view of the sun. The moon in front of the sun looks like a dark disk on top of a larger sun-coloured disk. This creates what looks like a ring around the moon.
    • During a solar eclipse, the moon casts two shadows on Earth. The first shadow is called the Umbra. This shadow gets smaller as it reaches Earth. It is the dark centre of the moon’s shadow.
    • The second shadow is called the Penumbra. The penumbra gets larger as it reaches Earth. People standing in the penumbra will see a partial eclipse. People standing in the umbra will see a total eclipse.

    Observing a Solar Eclipse

    • Solar eclipses happen once every 18 months.
    • Unlike lunar eclipses, solar eclipses only last for a few minutes.

    Why don’t solar eclipses happen at every New Moon?

    • The reason is that the Moon’s orbit tilts 5° to Earth’s orbit around the Sun.
    • Astronomers call the two intersections of these paths nodes.
    • Eclipses only occur when the Sun lies at one node and the Moon is at its New (for solar eclipses) or Full (for lunar eclipses) phase.
    • During most (lunar) months, the Sun lies either above or below one of the nodes, and no eclipse happens.

    [III] Planet Transits

    • When a planet comes between Earth and the Sun, it is called a transit.
    • The only 2 planets that can be seen transiting the Sun from Earth are Venus and Mercury because they are the only planets that orbit inside Earth’s orbit.
    • From 2000–2199, there will be 14 transits of Mercury.
    • However, Venus transits are even rarer with only 2 this century, in 2004 and 2012.

  • Banking Sector Reforms

    When does RBI step in to monitor a Bank?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: CAR, Basel Norms

    Mains level: Not Much

    The Reserve Bank of India (RBI) has placed a private bank under tight monitoring and greater public scrutiny.

    What is the news?

    • The XYZ Bank’s capital to risk weighted assets ratio (CRAR) dropped to around 13% at the end of March this year from 14.5% a year ago.
    • This has dropped below the Basel III in the past and it has even been placed under the prompt corrective action framework (PCA) by the RBI to deal with serious deteriorations in its financial position.
    • Under Basel-III norms banks are supposed to maintain their CRAR at 9% or above.

    What is Capital Adequacy Ratio (CAR)?

    • Capital adequacy ratio is an indicator of the ability of a bank to survive as a going business entity in case it suffers significant losses on its loan book.
    • The CRAR is a ratio that compares the value of a bank’s capital (or net worth) against the value of its various assets weighted according to how risky each asset is.
    • It is used to gauge the risk of insolvency faced by a bank.

    How do it affects bank functioning?

    • A bank cannot continue to operate if the total value of its assets drops below the total value of its liabilities as it would wipe out its capital (or net worth) and render the bank insolvent.
    • So, banking regulations such as the Basel-III norms try to closely monitor changes in the capital adequacy of banks in order to prevent major bank failures which could have a severe impact on the wider economy.
    • The capital position of a bank should not be confused with cash held by a bank in its vaults to make good on its commitment to depositors.

    Alternatives for bank

    • The said Bank has been trying to issue additional shares in the open market through a rights issue in order to deal with its capital adequacy woes.
    • Through a rights issue, the bank will be able to raise more equity capital from existing shareholders.
    • This is in contrast to an initial public offering where shares are issued to new shareholders.

    Back2Basics: Basel Norms

    • Basel is a city in Switzerland. It is the headquarters of the Bureau of International Settlement (BIS), which fosters co-operation among central banks with a common goal of financial stability and common standards of banking regulations.
    • Basel guidelines refer to broad supervisory standards formulated by this group of central banks – called the Basel Committee on Banking Supervision (BCBS).
    • The set of the agreement by the BCBS, which mainly focuses on risks to banks and the financial system is called Basel accord.
    • The purpose of the accord is to ensure that financial institutions have enough capital on account to meet obligations and absorb unexpected losses.
    • India has accepted Basel accords for the banking system.

    Basel I

    • In 1988, BCBS introduced a capital measurement system called Basel capital accord, also called as Basel 1.
    • It focused almost entirely on credit risk. It defined capital and structure of risk weights for banks.
    • The minimum capital requirement was fixed at 8% of risk-weighted assets (RWA).
    • RWA means assets with different risk profiles.
    • For example, an asset-backed by collateral would carry lesser risks as compared to personal loans, which have no collateral. India adopted Basel 1 guidelines in 1999.

    Basel II

    • In June ’04, Basel II guidelines were published by BCBS, which were considered to be the refined and reformed versions of Basel I accord.
    • The guidelines were based on three parameters, which the committee calls it as pillars:
    • Capital Adequacy Requirements: Banks should maintain a minimum capital adequacy requirement of 8% of risk assets.
    • Supervisory Review: According to this, banks were needed to develop and use better risk management techniques in monitoring and managing all the three types of risks that a bank faces, viz. credit, market and operational risks.
    • Market Discipline: This needs increased disclosure requirements. Banks need to mandatorily disclose their CAR, risk exposure, etc to the central bank. Basel II norms in India and overseas are yet to be fully implemented.

    Basel III

    • In 2010, Basel III guidelines were released. These guidelines were introduced in response to the financial crisis of 2008.
    • A need was felt to further strengthen the system as banks in the developed economies were under-capitalized, over-leveraged and had a greater reliance on short-term funding.
    • Also, the quantity and quality of capital under Basel II were deemed insufficient to contain any further risk.
    • Basel III norms aim at making most banking activities such as their trading book activities more capital-intensive.
    • The guidelines aim to promote a more resilient banking system by focusing on four vital banking parameters viz. capital, leverage, funding and liquidity.

    From UPSC perspective, the following things are important:

    Prelims level: Sukapaika River

    Mains level: Rejuvenation of River

    sukapaika

    Sukapaika, a small river that stopped flowing 70 years ago in Odisha’s Cuttack district is set to be rejuvenated.

    Sukapaika River

    • The Suka-paika (the dead) River originated from another river, the Mahanadi, near Ayatpur village.
    • It flowed 27.5 km before meeting the Mahanadi again at Bankala.
    • In the 1950s, the State’s water resource engineers had in their wisdom closed the Sukapaika river mouth enabling development of the Taladanda Canal System, a major canal of the State.
    • This led to the river mostly drying up.
    • The process was aggravated by agricultural encroachments that had sprung up on the riverbanks.

    Species in news: Great Indian Bustards

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Great Indian Bustard

    Mains level: NA

    bustard

    The recent sighting of three Great Indian Bustards (GIBs) deep in Pakistan’s Cholistan desert has given rise to speculation that the endangered birds might have flown across the international border from India.

    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.

    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: This has resulted in the electrocution of the bustards.
    • 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.

  • Tax Reforms

    What are Gift Taxes?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Gift Tax

    Mains level: NA

    The Supreme Court recently ruled that shares within the lock-in period are not ‘quoted shares’, and thus they need to be valued as ‘unquoted shares’ to determine the gift tax liability.

    What are quoted and unquoted shares?

    • According to the Wealth Tax Act, ‘quoted share’ in relation to an equity share or a preference share means a share quoted on any recognised stock exchange with regularity from time to time.
    • The quotations of such shares are based on current transactions made in the ordinary course of business.
    • An ‘unquoted share’ is simply a share that is not a quoted share.
    • So according to the SC order, if the locked-in shares of the promoter falls in the ‘unquoted share’ category, their price treatment can’t be that of the ‘quoted shares’, and so gift tax will not be applicable.

    What are Gift Taxes?

    • Gift tax is a provision introduced by the Parliament of India in 1958.
    • It was introduced to impose tax on giving and receiving gifts under certain circumstances which is specified under the act.
    • These gifts can be in any form including cash, jewellery, property, shares, vehicle, etc.

    Gift Tax on Transfers

    • The gift tax is also applicable on certain transfers that is not considered as a gift.
    • The transfer of existing movable or immovable property in money or money’s worth qualifies for gift tax.

    Certain exemptions

    • Though gift tax is applicable on gifts whose value exceeds Rs.50,000, the gift is exempted from tax if it was given by a relative.
    • The income tax rule specifies who can be considered as a relative and the list is mentioned below.
    1. Parent
    2. Spouse
    3. Siblings
    4. Spouse’s siblings
    5. Lineal descendants
    6. Lineal descendants of the spouse

    Listed below are other situations in which the gift will be exempted from tax.

    1. Gifts received during weddings are usually exempted from tax.
    2. Gifts received as part of inheritance is exempted from tax.
    3. Cash or rewards received by local authorities or educational institutions on the basis of merit is exempted from tax.

    What is Web 3.0?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Web 3.0

    Mains level: Not Much

    web

    India has a rapidly-growing Web3 ecosystem with more than 450 active start-ups in the space that raised $1.3 billion in funding till April 2022.

    What is Web 3.0?

    • Web3 help users interact with decentralized applications built on blockchain technology.
    • Web3 technologies like distributed ledgers, artificial intelligence, Metaverse and others aim to create the next-generation internet, which is accessible to everyone and offers benefits.
    • Web2 is what we know and use today.

    Why need Web 3?

    • Centralization has helped onboard billions of people to the World Wide Web (www) and created the stable, robust internet infrastructure.
    • At the same time, a handful of centralized entities have a stronghold on large swathes of the World Wide Web.
    • They unilaterally decide what should and should not be allowed over Internet.

    Key features of a Web3

    • Immutable ecosystem, i.e., trust that people will download the digital product just as the original creator intended.
    • Enhanced transparency and security,
    • Quicker browsing performance,
    • Complete user anonymity and confidentiality,
    • Integrating cryptocurrency wallets with multiple blockchains,
    • Complete control over the content due to decentralization.

    Evolution of (world-wide) web

    • The Web most of us know today is quite different from originally imagined.
    • To understand this better, it’s helpful to break the Web’s short history into loose periods—Web 1.0 and Web 2.0.

    (1) Web 1.0: Read-Only (1990-2004)

    • The first inception of ‘Web 1.0’, occurred roughly between 1990 to 2004.
    • It was mainly static websites owned by companies, and there was close to zero interaction between users – individuals seldom produced content – leading to it being known as the read-only web.

    (2) Web 2.0: Read-Write (2004-now)

    • The Web 2.0 period began in 2004 with the emergence of social media platforms.
    • Instead of a read-only, the web evolved to be read-write.
    • Instead of companies providing content to users, they also began to provide platforms to share user-generated content and engage in user-to-user interactions.
    • As more people came online, a handful of top companies began to control a disproportionate amount of the traffic and value generated on the web.
    • Web 2.0 also birthed the advertising-driven revenue model.
    • While users could create content, they didn’t own it or benefit from its monetization.

    How is Web3 prospected to be?

    • The premise of ‘Web 3.0’ was coined by Ethereum co-founder Gavin Wood shortly after Ethereum launched in 2014.
    • Gavin put into words a solution for a problem that many early crypto adopters felt: the Web required too much trust.
    • That is, most of the Web that people know and use today relies on trusting a handful of private companies to act in the public’s best interests.

    Core ideas of Web3

    Although it’s challenging to provide a rigid definition of what Web3 is, a few core principles guide its creation.

    • Web3 is decentralized: instead of large swathes of the internet controlled and owned by centralized entities, ownership gets distributed amongst its builders and users.
    • Web3 is permission-less: everyone has equal access to participate in Web3, and no one gets excluded.
    • Web3 has native payments: it uses cryptocurrency for spending and sending money online instead of relying on the outdated infrastructure of banks and payment processors.
    • Web3 is secure: It operates using incentives and economic mechanisms instead of relying on trusted third-parties.

    Why is Web3 important?

    • Ownership: Web3 gives you ownership of your digital assets in an unprecedented way. Web3 allows for direct ownership through non-fungible tokens (NFTs).
    • Censorship resistance: The power dynamic between platforms and content creators is massively imbalanced.
    • Decentralized autonomous organizations (DAOs): As well as owning your data in Web3, you can own the platform as a collective, using tokens that act like shares in a company.
