From UPSC perspective, the following things are important :
Prelims level: GDP computation and various terminologies
Mains level: National Income Accounting
The Ministry of Statistics and Programme Implementation (MoSPI) has released the First Advance Estimates (FAE) for the current financial year (2021-22 or FY22).
Tap to read more about:
National Income Determination, GDP, GNP, NDP, NNP, Personal Income
What is GDP?
- GDP measures the monetary value of all goods and services produced within the domestic boundaries of a country within a timeframe (generally, a year).
- It is slightly different from the other commonly used statistic for national income — the GNP.
- The Gross National Product (GNP) measures the monetary value of all goods and services by the people and companies of a country regardless of where this value was created.
GDP estimates for FY22
- According to MoSPI, India’s GDP will grow by 9.2 per cent in 2020-21.
- Last financial year, FY21, the GDP had contracted by 7.3%.
What are the First Advance Estimates of GDP?
- The FAE, which were first introduced in 2016-17, are typically published at the end of the first week of January.
- They are the “first” official estimates of how GDP is expected to grow in that financial year.
- But they are also the “advance” estimates because they are published long before the financial year (April to March) is over.
- It is important to note that even though the FAE are published soon after the end of the third quarter (October, November, December), they do not include the formal Q3 GDP data.
- Q3 data is published at the end of February as part of the Second Advance Estimates (SAE).
Significance of FAE
- Budgetary calculations: Since the SAE will be published next month, the main significance of FAE lies in the fact that they are the GDP estimates that the Union Finance Ministry uses to decide the next financial year’s budget allocations.
- Basis for nominal GDP: From the Budget-making perspective, it is important to note what has happened to nominal GDP — both absolute level and its growth rate. That’s because nominal GDP is the actual observed variable.
Note: Real GDP, which is the GDP after taking away the effect of inflation, is a derived metric. All Budget calculations start with the nominal GDP.
Real GDP = Nominal GDP — Inflation Rate
The difference between the real and nominal GDP shows the levels of inflation in the year.
How are the FAE arrived at before the end of the concerned financial year?
Ans. Benchmark-Indicator method
- The FAE are derived by extrapolating (uses ratio and proportion) the available data.
- The approach for compiling the Advance Estimates is based on Benchmark-Indicator method.
- In this, the estimates available for the previous year (2020-21 in this case) are extrapolated using relevant indicators reflecting the performance of sectors.”
What are the main takeaways?
#1 GDP Growth
- At 9.2%, the real GDP growth rate for FY22 is slightly lower than most expectations, including RBI’s, which pegged it at 9.5%.
- These estimates are based on data before the rise of the Omicron variant.
#2 Role of high inflation
- For FY22, while real GDP (with 2011-12 base prices) will grow by 9.2%, nominal GDP (calculated using current market prices) will grow by a whopping 17.6%.
- The difference between the two growth rates — about 8.5 percentage points — is essentially a marker of inflation (or the rate at which average prices have increased in this financial year).
#3 Private consumption continues to struggle
- The FAE analyses the three main contributors to GDP — private consumption demand, investments in the economy, and government expenditures.
- It shows that while the latter two are expected to claw back to the pre-Covid level, the first engine will continue to stay in a slump.
#4 Average Indian is much worse off
- For the bulk of the Indian population, thus, aggregate data recovering to pre-Covid levels are largely academic.
- An average Indian has lost almost 2 years in terms of income levels and 3 years in terms of spending levels.
Try this PYQ:
Q. In the context of Indian economy, consider the following statements:
- The growth rate of GDP has steadily increased in the last five years.

Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2

From UPSC perspective, the following things are important :
Prelims level: Gene sequencing, RTPCR
Mains level: COVID diagnosis
Omisure — India’s first home-grown testing kit has recently received approval from the Drugs Controller General of India.
About Omisure
- Omisure is an omicron detecting RT-PCR kit developed by the Mumbai-based Tata Medical and Diagnostics Ltd (TATA MD) in partnership with the Indian Council of Medical Research (ICMR).
- It can differentiate the omicron strain of the novel coronavirus from the delta, alpha and the other variants in under four hours.
- It can diagnose this variant in a single step
How does it work?
- This new kit can identify the Omicron variant by targeting two regions of the S or the spike gene.
- This gene codes for the spike protein, which helps the novel coronavirus enter and infect human cells.
- The S, the Enveloped (E), and Nucleocapsid (N) genes are some of the targets of conventional RT-PCR tests.
- When it detects these genes, a patient sample is labelled positive. As omicron bears heavy mutations in the S gene, the RT-PCR can sometimes miss it.
- The absence of S gene likely indicates omicron’s presence.
- This is called S gene dropout or S gene target failure — and is one of the targets of Omisure.
How does Omisure compare with gene sequencing?
- Gene sequencing reads the order of nucleotides, which are the building blocks of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
- Despite being considered the gold standard, sequencing has a few limitations.
- It is slow, expensive and complicated. It is a multi-step process.
- It begins with extracting the virus’ RNA from patient samples, converting it into DNA, amplifying or multiplying it through RT-PCR before finally sending it for gene sequencing.
- This entire process can take as many as three days.

From UPSC perspective, the following things are important :
Prelims level: Indian Rock System
Mains level: NA
The Ministry of Science & Technology has inaugurated India’s first open rock museum displaying different types of rocks gathered from different States of ages ranging from 3.3 billion years to around 55 million years.
Rock System in India
Based on this complex and varied geological history, the Geological Survey of India has classified rock systems of the country into 4 major divisions:
- Archaean Rock System
- Dravidian Rock System
- Purana Rock System
- Aryan Rock System
[I] Archaean Rock System:
The Archaean group of rocks consists of two systems-(a) Achaean granites and gneisses, and (b) Dharwarian sedimentary:
Archaean Gneisses and Schists (pre-2500 million years)
- The Archean System contains the first formed rocks of the earth.
- The rocks are primarily gneisses and granites, having no marks of fossils.
- They often underlie the strata formed subsequently and the system is generally known as the basement complex or fundamental gneisses.
- The Archaean rocks cover two-thirds of peninsular India. They also occur in the roots of the mountain peaks all along the Greater Himalayas, trans-Himalayan ranges of Zaskar, Ladakh and Karakoram.
Dharwar System (2500-1800 million years ago)
- The weathering of the Archaean rocks yielded the earliest sediments and formed the oldest sedimentary strata, the Dharwar system.
- These are found today in metamorphic forms and do not contain fossils.
- These rocks occur in scattered patches in parts of Karnataka, Tamil Nadu, central and eastern parts of Chotanagpur plateau, Meghalaya plateau, Aravalis, Himalayan region etc
Mineral contents:
- They contain gneisses (which range from granite to gabbro) and schists (crystalline rocks such as mica, talc etc.).
- These rocks have metallic and non-metallic minerals like copper, tin, graphite, lead, zinc, etc.
[II] Dravidian Rock System:
- This is also known as carboniferous rock system and formed during the Paleozoic era, i.e., from 600- 300 million years ago.
- They are not much abundant in India.
- They have plentiful fossils and beginning of coal formation can be seen in this period. The quality of carboniferous coal is high.
- They are found in extra- Peninsular regions of the Himalayas and the Gangetic plains.
Mineral content
- This type of rock system comprises of limestones, shale and quartzite and Mount Everest is formed of upper Carboniferous limestones.
- Most of the coal is not of the Carboniferous period, which is found in India.
- The meaning of Carboniferous in geology is coal-bearing.
[III] Purana Rock System:
The Purana rock system has two divisions: Cuddapah system and Vindhyan system. The word ‘Purana’ was used in place of a Proterozoic era in India.
Cuddapah Rock system:
- They are observed in Cuddapah districts of Andhra Pradesh.
- The non-fossiliferous clay, slates, sandstones and limestones were accumulated in the depression between two-fold mountains which is known as synclinal basins.
- They also have a large accumulation of building purpose cement grade limestones and quartzites.
- This type of rock contains ore of iron, cobalt, nickel, manganese etc.
Vindhya Rock System:
- This type of rock system is also ancient or old sedimentary rocks which are superimposed on the Archaean rock base and derived its name from Vindhya mountains.
- The recognition of fossils is negligible, only traces of few animal and plant life were found.
- This rock system has diamond-bearing regions from which Golconda and Panna diamond mined.
[IV] Aryan Rock System
The Aryan rock system in India has the following four subsystems:
- Gondwana rock system
- Jurassic Rock System
- Cretaceous system/ Deccan Trap
- Tertiary rock system
(1) Gondwana Rock System:
- These are found mainly in Raniganj, Jharia regions of Jharkhand, Damodar valley, Pench valley in Chhattisgarh and Madhya Pradesh.
- They are called so after the name of Gondwana tribe (indigenous people especially residing in Telangana and Andhra Pradesh region).
- In this type of rock system, you found metallic minerals like iron, manganese, uranium etc. other than coal.
- They have low carbon content as it is much younger than Carboniferous coal. These rocks have nearly 98% of India’s coal reserve.
(2) Jurassic Rock System
- During the latter part of Jurrasic when sea level rises as compared to land and shoreline moves towards ground or land which result in a flood. In geology, this phenomenon is called marine transgression.
- This gives rise to a thick series of shallow-water deposits kin Rajasthan and Kutch. Between the Guntur and Rajamundry, another transgression in the east coast of Peninsula.
- In Kuchchh, coral limestone, shales and conglomerates are found.
(3) Deccan traps
- These are formed by the flow of magma over the solidified rock system in layers.
- Deccan trap gets rise due to volcanic outburst over a major area of Peninsular India from the end of Cretaceous till the beginning of Eocene.
- The meaning of trap is “stair” or “step” in Swedish and called due to deposition of the volcanic outburst which has a flat top and steep sides.
- It is mainly found in parts of Kuchchh, Saurashtra, Maharashtra, the Malwa plateau and Northern Karnataka and presently cover near 5 lakh sq. Km.
- Regur, which is black soil, is formed due to the weathering of these rocks for a long time.
(4) Tertiary rock system
- The formation of this type of rock system occurs from 60 to 7 million years ago.
- It is the most noteworthy period in India’s geological history as the Himalayas were born and recent form came in this period.

From UPSC perspective, the following things are important :
Prelims level: Antrix
Mains level: Read the attached story
A Canadian court has ordered the seizure of more than $30 million worth of Airport Authority of India’s assets.
Background
- In 2005, Devas Multimedia signed an agreement with Antrix —a commercial arm of the IISRO —to provide multimedia services to mobile users using the leased S-band satellite spectrum to be provided by Antrix.
- In 2011, the UPA-2 government canceled this agreement on the ground that it needed the S-band satellite spectrum for national security and other social purposes.
- This led to arbitration between Antrix and Devas at the International Chambers of Commerce (ICC) and two bilateral investment treaty (BIT) arbitrations. India lost all three disputes.
India’s non-compliance
- AAI and Air India are being targeted because they are Indian public sector entities with overseas assets and serve as a proxy for the government of India.
- The Canada court can do so through the concept of restrictive immunity.
- In the meanwhile, the National Company Law Tribunal (India) ordered the liquidation of Devas Multimedia on the ground that the affairs of the company were being carried on fraudulently.
Why did India cancel the deal?
- The scandal first came to light when in 2011, the news reported that there were some irregularities in the agreement between Antrix and Devas.
- They reported the findings of a draft audit report and pointed out discrepancies including financial mismanagement, conflict of interest, non-compliance of rules, and favoritism.
- This revelation came at the heel of the 2G spectrum scam which was condemned for the high level of corruption.
How can a Canadian court order the attachment of Indian assets?
- State immunity — a well-established principle of international law — shields a state and its property against legal proceedings in the courts of other countries.
- This covers immunity from both jurisdiction and execution.
- However, there is no international legal instrument in force dealing with state immunity in the municipal legal systems of different countries, which has created an international void.
- Consequently, countries have filled this void through their national legislations and domestic judicial practices on state immunity.
- Typically, prominent jurisdictions such as Canada follow the concept of restrictive immunity (a foreign State is immune only for sovereign functions) and not absolute immunity.
How can assets of AAI be seized when the claim is against India?
- In execution proceedings, assets of an entity can be seized if that entity is an alter ego of the State that fails to comply with the arbitral award.
- In other words, if the foreign sovereign exercises such extensive control over the entity, then the presumption that the entity has a separate corporate character is set aside.
- Thus, the Canadian court must have concluded that the Indian government extensively controls AAI.
What options does India have?
- The first option is to comply with the two adverse BIT awards. However, it is highly unlikely that India would do so.
- The second option is to challenge this decision in an appellate court in Canada as per Canadian law where India can try proving that the ‘extensive control requirement’ is not met in the case of AAI.
- However, state immunity from execution is purely a procedural hurdle to the enforcement of the BIT award.
- It cannot justify India’s breach of its international law obligations enshrined in the two BITs and the continued failure to comply with the arbitral awards.
Back2Basics: New Space India Limited (NSIL)
- It functions under the administrative control of the Department of Space (DOS).
- It aims to commercially exploit the research and development work of ISRO Centres and constituent units of DOS.
- The NSIL would enable Indian Industries to scale up high-technology manufacturing and production base for meeting the growing needs of the Indian space program.
- It would further spur the growth of Indian Industries in the space sector.
ANTRIX
- Antrix Corporation Limited (ACL), Bengaluru is a wholly-owned Government of India Company under the administrative control of the Department of Space.
- It is as a marketing arm of ISRO for promotion and commercial exploitation of space products, technical consultancy services and transfer of technologies developed by ISRO.
- Antrix is engaged in providing Space products and services to international customers worldwide.

From UPSC perspective, the following things are important :
Prelims level: Takhts in Sikhism
Mains level: Not Much
The Delhi Assembly has passed an amendment Bill to the Delhi Sikh Gurdwara Act, 1971, recognizing Takht Damdama Sahib as the fifth Takht of Sikhs.
What is a Sikh Takht?
- A Takht, which means a throne, is a seat of temporal authority for Sikhs.
- There are five Sikh Takhts, three in Punjab and one each in Maharashtra and Bihar.
(1) Akal Takht
- Located in Amritsar, it is the oldest of the Takhts, and considered supreme among the five.
- It was set up in 1606 by Guru Hargobind, whose succession as the sixth Guru after the execution of his father, Guru Arjan Dev, is considered a turning point in Sikh history.
- The Akal Takht, a raised platform that he built in front of the causeway leading to the sanctum sanctorum of the Harmandir Sahib (Golden Temple).
- It symbolised the coming together of the temporal authority and the political sovereignty of the Sikh community (miri) with the spiritual authority (piri).
- It is seen as the first marker of Sikh nationalism.
The other four Takhts are linked to Guru Gobind Singh, the tenth Sikh Guru.
(2) Takht Keshgarh Sahib
- Located in Anandpur Sahib in Punjab. It was here that Guru Gobind Singh raised Khalsa, the initiated Sikh warriors, in 1699.
(3) Takht Patna Sahib
- Guru Gobind Singh was born here in 1666.
(4) Takht Hazur Sahib
- In Nanded, where Guru Gobin Singh spent time and where he was cremated in 1708.
(5) Takht Damdama Sahib
- In Talwandi Sabo of Bathinda. Guru Gobind Singh spent several months here.
What does the amendment to the Delhi Sikh Gurdwara Act mean?
- Simply put, it adds one more ex officio member in the Delhi Sikh Gurdwara Managament Committee (DSGMC) house.
- Earlier, there were four ex officio members in the house — the chiefs (jathedars) of the other four Sikh Takhts.
Is it the first time it has been recognised as the fifth Takht?
- It was back in 1999 that Takht Damdama Sahib was recognised as the fifth Sikh Takht by the Union Home Ministry.
- It included it as such in the Sikh Gurdwaras Act, 1925 (Punjab Act VIII of 1925) with a notification dated April 23, 1999.
- Before that, an SGPC sub-committee had declared it the fifth Takht of Sikhs back in November 1966 after Punjab was carved out as a separate state through the Punjab Reorganisation Act, 1966.
How politically significant is the move?
- It comes ahead of the Punjab Assembly elections, where the, Delhi’s ruling party, has high stakes.
What is the role of the Sikh Takhts?
- The Takhts are known to issue hukumnamas (morality orders) from time to time on issues that concern the Sikh community.
- Akal Takht is supreme among them because it is the oldest and was created by a Sikh Guru himself, say Sikh scholars.
- Any edict or order concerning the entire community is issued only from Akal Takht.
- It is from Akal Takht that Sikhs found to be violating the Sikh doctrine and code of conduct are awarded religious punishment (declared tankhaiya).
Who appoints the jathedars of the Takhts?
- The three Takhts in Punjab are directly controlled by the SGPC, which appoints the jathedars.
- The SGPC is dominated by SAD members.
- It is widely understood that SAD puts the final seal on the appointment of these three jathedars.
- The two Takhts outside Punjab have their own trusts and boards.

From UPSC perspective, the following things are important :
Prelims level: Types of vaccines
Mains level: Effectiveness of various vaccines against COVID
Vaccines like Biological E’s Corbevax and Bharat Biotech’s Covaxin that are made by traditional methods are “just as effective” as the latest mRNA technology-based vaccines a/c to US scientists.
What are Vaccines?
- A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease.
- It typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins.
Types of Vaccines
There are several types of vaccines, including:
- Inactivated vaccines
- Live-attenuated vaccines
- Messenger RNA (mRNA) vaccines
- Subunit, recombinant, polysaccharide, and conjugate vaccines
- Viral vector vaccines
[1] Inactivated vaccines
- Inactivated vaccines use the killed version of the germ that causes a disease.
- Inactivated vaccines usually don’t provide immunity (protection) that’s as strong as live vaccines.
- So you may need several doses over time (booster shots) in order to get ongoing immunity against diseases.
- Inactivated vaccines are used to protect against: Hepatitis A, Flu (shot only), Polio (shot only), Rabies etc.
[2] Live-attenuated vaccines
- Live vaccines use a weakened (or attenuated) form of the germ that causes a disease.
- Because these vaccines are so similar to natural infection that they help prevent, they create a strong and long-lasting immune response.
- Just 1 or 2 doses of most live vaccines can give you a lifetime of protection against a germ and the disease it causes.
- They need to be kept cool in refrigerated conditions.
- Live vaccines are used to protect against Measles, mumps, rubella (MMR), Rotavirus, Smallpox, Chickenpox, Yellow fever
[3] Messenger RNA vaccines
- Researchers have been studying and working with mRNA vaccines for decades and this technology was used to make some of the COVID-19 vaccines.
- mRNA vaccines make proteins in order to trigger an immune response.
- mRNA vaccines have several benefits compared to other types of vaccines, including shorter manufacturing times and, because they do not contain a live virus, no risk of causing disease in the person getting vaccinated.
How does mRNA vaccine work?
- The mRNA vaccines function differently from traditional vaccines.
- Traditional vaccines stimulate an antibody response by injecting a human with antigens.
- mRNA vaccines inject a fragment of the RNA sequence of a virus directly into the cells, which then stimulate an adaptive immune response mRNA fragment is a specific piece of the virus that carries instructions to build the antigen of the virus.
- An advantage of RNA vaccines is that they stimulate cellular immunity.

From UPSC perspective, the following things are important :
Prelims level: Western Disturbances
Mains level: Not Much
Under the influence of two consecutive western disturbances, New Delhi is in for a wet spell.
Western Disturbances
- A western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.
- It is a non-monsoonal precipitation pattern driven by the westerlies.
- The moisture in these storms usually originates over the Mediterranean Sea, the Caspian Sea and the Black Sea.
- Extratropical storms are global phenomena with moisture usually carried in the upper atmosphere, unlike their tropical counterparts where the moisture is carried in the lower atmosphere.
- In the case of the Indian subcontinent, moisture is sometimes shed as rain when the storm system encounters the Himalayas.
- Western disturbances are more frequent and strong in the winter season.
Impact: Winter Rainfall and Extreme Cold
- Western disturbances, specifically the ones in winter, bring moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent.
- They are the cause of most winter and pre-monsoon season rainfall across northwest India.
- An average of four to five western disturbances forms during the winter season.
Its significance
- Precipitation during the winter season has great importance in agriculture, particularly for the rabi crops.
- Wheat among them is one of the most important crops, which helps to meet India’s food security.

From UPSC perspective, the following things are important :
Prelims level: MAC, NATGRID
Mains level: Counter-terrorism ops and security agencies
The Union government has asked the States to share more intelligence inputs through the Multi Agency Centre (MAC), a common counter-terrorism grid under the Intelligence Bureau (IB).
Why in news?
- States are often reluctant to share information on the platform.
- There are several gaps in sharing critical information at the right time.
- Plans are afoot for more than a decade to link the system up to the district level.
About MAC
- The Multi-Agency Centre (MAC) was formed in December 2001 following the Kargil intrusion and the subsequent overhaul of the Indian national security apparatus suggested by the Kargil Review Committee report.
- Accordingly, the Intelligence Bureau (IB) was authorized to create a multi-agency centre (MAC) in New Delhi.
- Now functioning 24×7 as the nodal body for sharing intelligence inputs, MAC coordinates with representatives from numerous agencies, different ministries, both central and state.
- Various security agencies share real-time intelligence inputs on the MAC.
- The state offices have been designated as subsidiary MACs (SMACs).
- As many as 28 organisations, including the Research and Analysis Wing (R&AW), armed forces and State police, are part of the platform.
Back2Basics: NATGRID
- NATGRID is an intelligence-sharing network that collates data from the standalone databases of the various agencies and ministries of the Indian government.
- It collects and collates a host of information from government databases including tax and bank account details, credit/debit card transactions, visa and immigration records and itineraries of rail and air travel.
- It came into existence after the 2008 Mumbai attacks.
- It is accessible to only authorized people from 10 security agencies on a case-to-case basis for investigations into suspected cases of terrorism.
- It will also have access to the Crime and Criminal Tracking Network and Systems, a database that links crime information, including First Information Reports, across 14,000 police stations in India.
Note: NATGRID data will be made available to 11 central agencies, which are: Research and Analysis Wing (R&AW), Intelligence Bureau (IB), National Investigation Agency (NIA), Central Bureau of Investigation (CBI), Narcotics Control Bureau (NCB), Financial Intelligence Unit (FIU), Enforcement Directorate (ED), Central Board of Direct Taxes (CBDT), Central Board of Indirect Taxes and Customs (CBIC), Directorate of Revenue Intelligence (DRI) and Directorate General of GST Intelligence.

- The eligible cryptocurrency should have traded on at least 90% of the days during the review period and be among the 100 most liquid cryptocurrencies in terms of trading value.
- Also, the cryptocurrency should be in the top 50 in terms of the circulating market capitalization.
- The committee will then select the top 15 cryptocurrencies. The index will be reviewed quarterly.
What is its significance?
- IC15 can be replicated for creating index-linked products such as index funds or exchange-traded funds (ETFs).
- Usually, the performance of a mutual fund scheme is assessed with reference to a benchmark, which could be a total return index of the Nifty or the Sensex.
- IC15 is the first index in India that can act as a benchmark of the underlying cryptocurrency market and the performance benchmark for fund managers.
- Moreover, robo-advisors, which provide financial advice with moderate to minimal human intervention, can use this index to create investment products at lower costs.
How does IC15 correlate with other market indicators?
- IC15’s base value as on 1 April 2018 was 10,000.
- It would mean that the index has gained 615% in absolute terms to 71,475.48 till 31 December 2021.
Can index-based crypto investment reduce risks?
- Index investing can be an effective way to diversify against risks as a fund invests in a basket of assets against a few limited coins.
- However, index-based investing may not fully remove risks associated with investing in crypto assets.
- Case in point: IC15 saw a 50% plunge in 2018, whereas other asset classes have seen a maximum drop in the range of 3-4%.
- Further, bitcoin and ethereum have a combined weightage of 77% in the index, making it highly vulnerable to any volatility in these two coins.
Can crypto funds be launched in India?
- SEBI has recently asked mutual fund houses not to launch crypto-based funds until the Centre comes out with clear regulations.
- This means asset management companies for now won’t be able to launch crypto funds based on IC15.
- However, in the absence of any regulations, crypto platforms can offer products based on the index.
- Global crypto investment platform Mudrex last year launched Coin Sets—crypto funds based on themes such as decentralized finance or market cap.

From UPSC perspective, the following things are important :
Prelims level: Nai Talim
Mains level: Not Much
The Vice President of India has said that the New Education Policy follows the ‘Nai Talim’ of Mahatma Gandhi by giving importance to the mother tongue as the medium of instruction at the school level.
What is Nai Talim?
- The phrase Nai Talim is a combination of two words- Nai Means ‘New’ and Talim – a Urdu word-means ‘Education’.
- In 1937, Gandhiji introduced the concept of Nai Talim in India. It aimed to achieve Gram Swaraj (liberation of villages).
- In short, Gandhiji dreamed to make all villages independent; and self-reliant.
- It is an approach to the total personality development of body, mind and spirit and was based on four principles namely:
- Education or learning in mother tongue along with handicraft work,
- Work should be linked with most useful vocational needs of the locality,
- Learning should be linked with vocational work, and
- Work should be socially useful and productive needed for living.
Gandhiji and Education
- Gandhi’s first experiments in education began at the Tolstoy Farm ashram in South Africa.
- It was much later, while living at Sevagram (Wardha) and in the heat of the Independence struggle, that Gandhi wrote his influential article in Harijan about education.
- In it, he mapped out the basic pedagogy (or teaching) with focus on:
- Lifelong character of education,
- Social character and
- A holistic process
- Thus, for Gandhi, education is ‘the moral development of the person’, a process that is by definition ‘lifelong’.
- He believed the importance of role of teacher in the learning process.

From UPSC perspective, the following things are important :
Prelims level: Non-Nuclear Aggression Agreement
Mains level: Nuclear Non-Proliferation
India and Pakistan has exchanged a list of their nuclear installations that cannot be attacked in case of an escalation in hostilities, as part of an annual ritual that has been in practice between the two neighbours for more than three decades.
Non-Nuclear Aggression Agreement
- The Non-nuclear aggression agreement is a bilateral and nuclear weapons control treaty between India and Pakistan, on the reduction (or limitation) of nuclear arms.
- Both pledged not to attack or assist foreign powers to attack on each others nuclear installations and facilities.
- The treaty was drafted in 1988, and signed by the PM Rajiv Gandhi and his counterpart Benazir Bhutto on 21 December 1988; it entered into force on January 1991.
- The treaty barred its signatories to carry out a surprise attack (or to assist foreign power to attack) on each other’s nuclear installations and facilities.
- Starting in January 1992, India and Pakistan have annually exchanged lists of their respective military and civilian nuclear-related facilities.
Need for the treaty
- In 1986-87, the massive exercise, ‘Brasstacks’ was carried out by the Indian Army, raising the fears of an Indian attack on Pakistan’s nuclear facilities.
- Since then, the Foreign ministries of both countries had been negotiating to reach an understanding towards the control of nuclear weapons.
Significance of the agreement
- The treaty barred its signatories to carry out a surprise attack (or to assist foreign power to attack) on each other’s nuclear installations and facilities.
- The treaty provides a confidence-building security measure environment.
Other: Sharing of Prisoners information
- Both nations do simultaneously share the list of prisoners in each others’ custody.
- These lists are exchanged under the provisions of the Agreement on Consular Access signed in May 2008.
- Under this pact, the two countries should exchange comprehensive lists on January 1 and July 1 every year (i.e. twice a year).

From UPSC perspective, the following things are important :
Prelims level: Semiconductor, Rare earth elements
Mains level: Electronic industry
Worldwide carmakers have slashed production due to an abrupt and cascading shortage of semiconductors.
Semiconductor Chips
- Semiconductors — also known as integrated circuits (ICs), or microchips — are most often made of silicon or germanium, or a compound like gallium arsenide.
- It’s the thing that makes electronic items smart and faster.
- Made from a material, usually silicon, that “semi-conducts” electricity, the chip performs a variety of functions.
- Memory chips, which store data, are relatively simple and are traded like commodities.
- Logic chips, which run programs and act as the brains of a device, are more complex and expensive.
Reasons for shortages
- Stay-at-home shift: This pushed chip demand beyond levels projected before the pandemic. Lockdowns spurred growth in sales of smartphones, laptops etc to the highest in a decade
- Fluctuating forecasts: Automakers that cut back drastically early in the pandemic underestimated how quickly car sales would rebound.
- Stockpiling: Chinese smartphone industry dominates the global market for 5G networking gear — began building up inventory to ensure it could survive US sanctions.
How is the chip crisis playing out in geopolitics?
- The global chip crisis and geopolitical tensions with China have shifted focus back on semiconductors.
- The US, which was once a leader in chip manufacturing, wants the crown back.
- The protectionist US is looking to bring manufacturing back to America and reduce its dependency on a handful of chipmakers mostly concentrated in Taiwan and South Korea.
- China’s renewed aggression on Taiwan is also being seen in light of the chip crisis.
Impact of semiconductor shortages
- Chip shortages are expected to wipe out $210 billion of sales for carmakers this year, with the production of 7.7 million vehicles lost.
- Broadband providers were facing delays of more than a year when ordering internet routers.
Why is it so hard to compete?
- Manufacturing advanced logic chips requires extraordinary precision, along with huge long-term bets in a field subject to rapid change.
- Plants cost billions of dollars to build and equip, and they have to run flat-out 24/7 to recoup the investment.
- A factory also consumes up enormous amounts of water and electricity and is vulnerable to even the tiniest disruptions, whether from dust particles or distant earthquakes.

From UPSC perspective, the following things are important :
Prelims level: INSACOG
Mains level: Not Much
The Indian SARS-CoV-2 Consortium on Genomics (INSACOG) has sequenced about 1,00,000 samples.
What is INSACOG?
- INSACOG is a consortium of 10 labs and 18 satellite labs across India tasked with scanning COVID samples from patients and finding the variants that has led to spike in transmission.
- The institutes involved include the laboratories of the Department of Biotechnology, Council of Scientific and Industrial Research, Indian Council of Medical Research, and the Health Ministry.
- Its work began in January 2020, by sequencing all samples with a history of travel from the U.K. and a proportion of positive samples in the community.
Tasks of INSACOG
- The NCDC is tasked with coordinating collections of samples from the States as well as correlating disease with certain mutations.
- It is mainly involved in genomic sequencing which is done by isolating the genetic material of the coronavirus samples.
- It is also tasked with tracking certain combinations of mutations that become more widespread in India.
What has it found so far?
- The INSACOG sequenced about 1,00,000 samples as of early December 2021 when this data was last made publicly available.
- The bulk of its effort has been focussed on identifying international ‘variants of concern’ (VoC) that are marked out by the WHO as being particularly infectious or pathogenic.
- International travellers who arrive in India and test positive are the ones whose samples usually get sent to INSACOG for determining the genomic variant.
Why is genome sequencing useful?
- Understanding mutations: The purpose of genome sequencing is to understand the role of certain mutations in increasing the virus’s infectivity.
- Immune response: Some mutations have also been linked to immune escape, or the virus’s ability to evade antibodies, and this has consequences for vaccines.
- Effectiveness of vaccines: Labs across the world, including many in India, have been studying if the vaccines developed so far are effective against such mutant strains of the virus.
- Evolution of viruses: Studies such as this have shown that Omicron, for instance, has evolved to evade antibodies much better than the Alpha or Delta variant. This prompted the push towards booster doses.
How is it done?
- Genomic sequencing is done by isolating the genetic material (RNA) of the coronavirus samples.
- RNA consists of millions of nucleotide bases and genomic sequencing is about identifying and comparing the sequence in a given sample to a reference sample.
- Changes in the sequence are clues to mutations that show that the virus may have undergone distinct changes at some key locations.
- There are several approaches to genome sequencing — whole genome sequencing, next-generation sequencing — that have different advantages.
- It has now evolved to a stage where large sequencers can process even thousands of samples simultaneously.
Various challenges that INSACOG faces
- Geographical variations: Given that COVID-19 is spreading, mutating and showing geographical variations, the original aim of the group was to sequence at least 5% of COVID-19 samples.
- Shortage of funds: But only 1% has been achieved yet, primarily due to a shortage of funds, insufficient reagents and tools necessary to rapidly scale up.
- Red-tapism: The INSACOG, in spite of being peopled by expert scientists, is ultimately within the Central government’s communication structure.
- Infrastructure lacunae: Not all INSACOG labs have the same quality of equipment and manpower and therefore a surge or spike in some cities can mean difficulties in processing.

From UPSC perspective, the following things are important :
Prelims level: Solid-state lithium ion battery
Mains level: Battery Technology for e-Vehicles boost
After Twitter CEO Parag Agrawal, now another Indian origin is in the headline is Jagdeep Singh, CEO and founder of a US battery startup. The reason for his recent buzz for his breakthrough battery technology.
About QuantumScape
- QuantumScape Corp is a battery startup backed by Volkswagen AG.
- Its solid-state battery — lithium metal with a solid electrolyte separating the two electrodes — is seen as an exceptionally bright prospect in E-Vehicle industry.
What are Solid-state batteries?
- A solid-state battery is a battery technology that uses solid electrodes and a solid electrolyte, instead of the liquid or polymer gel electrolytes found in lithium-ion or lithium polymer batteries.
- Such batteries can provide potential solutions for many problems of liquid Li-ion battery, such as flammability, limited voltage, unstable solid-electrolyte interphase formation, poor cycling performance and strength.
What are Li-ion Batteries?
- Lithium-ion batteries use aqueous electrolyte solutions, where ions transfer to and fro between the anode (negative electrode generally made of graphite) and cathode (positive electrode made of lithium), triggering the recharge and discharge of electrons.
- The energy density of lithium-ion cells used in today’s mobile phones and electric vehicles is nearly four times higher than that of older-generation nickel-cadmium batteries.
Its limitations
- Low energy density: Despite improvements in technology over the last decade, issues such as long charging times and weak energy density persist.
- Small appliances: While lithium-ion batteries are seen as sufficiently efficient for phones and laptops, they still lack the range that would make EVs a viable alternative.
- Extreme reactivity: One major problem is that lithium metal is extremely reactive.
- Corrosion of cells: The main form of lithium corrosion is dendrites (branched lithium structures) that grow out from the electrode and can potentially pierce the separator short-circuiting the cell.
- Fire hazard: In current lithium-ion batteries, in which the electrolyte is a flammable liquid, dendrite formation can trigger a fire.
What is the breakthrough?
- QuantumScape claims to prevent dendrites formation.
- It uses a solid-state separator technology that eliminates the side reaction between the liquid electrolyte and the carbon/graphite in the anode of conventional lithium-ion cells.
- The replacement of the separator enables the use of a lithium-metal anode in place of the traditional
- The lithium metal anode is more energy-dense than conventional anodes, which allows the battery to store more energy in the same volume, according to the company.
Key advantages of QuantumScape Battery
- The advantages of the solid-state battery technology include higher cell energy density (by eliminating the carbon anode), lower charge time (by eliminating the need to have lithium diffuse into the carbon particles in conventional lithium-ion cells).
- It has the ability to undertake more charging cycles and thereby a longer life, and improved safety.
- Lower cost could be a game-changer, given that at 30 per cent of the total cost, battery expenses are a key driver of the vehicle costs.
India’s battery push
- The centre is working on a blueprint for a project of around 4,000 MWh of grid-scale battery storage system at the regional load dispatch centres that control the country’s power grid, primarily to balance the vagaries of renewable generation.
- Reliance Industries Ltd has announced plans to set up an Energy Storage Giga factory; state-owned NTPC Ltd has floated a global tender for a grid-scale battery storage project.
- The Ministry of Heavy Industries issued a request for proposal for setting up manufacturing facilities for Advanced Chemistry Cell (ACC) battery storage in India.
