From UPSC perspective, the following things are important :
Prelims level: Theri Desert in Tamil Nadu
Mains level: Desertification of land and preventive measures
Most of us may not know the small desert situated in the state of Tamil Nadu. It consists of red sand dunes and is confined to the Thoothukudi district.
Theri Desert
- The red dunes are called theri in Tamil.
- They consist of sediments dating back to the Quaternary Period and are made of marine deposits.
- They have very low water and nutrient retention capacity.
- The dunes are susceptible to aerodynamic lift.
- This is the push that lets something move up. It is the force that is the opposite of weight.
Mineral composition of Theris
- The analysis of the red sand dunes reveal the presence of heavy and light minerals.
- These include Ilmenite, Magnetit, Rutile, Garnet, Zircon, Diopside, Tourmaline, Hematite, Goethite, Kyanite, Quartz, Feldspar, Biotite.
- The iron-rich heavy minerals like ilmenite, magnetite, garnet, hypersthene and rutile present in the soil had undergone leaching by surface water.
- They were then oxidised because of the favourable semi-arid climatic conditions.
How did they form?
- Theris appear as gentle, undulating terrain.
- The lithology of the area shows that the area might have been a paleo (ancient) coast in the past.
- The presence of limestone in many places indicates marine transgression.
- The present-day theris might have been formed by the confinement of beach sand locally, after regression of the sea.
- When high velocity winds from the Western Ghats blew east, they induced migration of sand grains and accumulation of dunes.
Another story of their formation
- Another view is that these are geological formations that appeared in a period of a few hundred years.
- The red sand is brought from the surface of a broad belt of red loam in the plains of the Nanguneri region (about 57 kilometres) by south west monsoon winds during May-September.
- The winds after draining the moisture behind the Mahendragiri hill and the Aralvaimozhi gap of the Western Ghats become dry and strike the plains in the foothills, where vegetation is sparse.
- Deforestation and the absence of vegetative cover in the Aralvaimozhi gap and the Nanguneri plains are considered to be the major causes of wind erosion.

From UPSC perspective, the following things are important :
Prelims level: Black Death
Mains level: NA
In a study published in the Science journal, researchers have claimed that the bubonic plague was originated in modern day northern Kyrgyzstan around 1338-1339 – nearly 7-8 years before it ravaged large parts of the world.
What is Black Death?
- The term Black Death refers to the bubonic plague that spread across Western Asia, Northern Africa, Middle East and Europe in 1346-53.
- Most scholars agree that the Black Death, which killed millions, was caused by bacterium Yersinia pestis and was spread by fleas that were carried by rodent hosts.
- The microorganism Y. pestis spread to human populations, who at some point transmitted it to others either through the vector of a human flea or directly through the respiratory system.
Why this plague was called the Black Death?
- It is commonly believed that the term Black Death gets its name from the black marks that appeared on some of the plague victims’ bodies.
- In the 14th century, the epidemic was referred to as the ‘great pestilence’ or ‘great death’, due to the demographic havoc that it caused.
- The world black also carried a dark, gloomy emotional tone, due to the sheer amount of deaths generated by the plague.
Why is the new discovery significant?
- The geographical origin point of the plague has been debated for centuries.
- Some historians have argued that the plague originated in China, and spread across Europe by Italian merchants who first entered the continent in trading caravans through Crimea.
- Another story argues that Mongol army hurled plague-infested bodies into the city during the siege of Caffa (Crimea) and led to the spread of the disease.

From UPSC perspective, the following things are important :
Prelims level: 5G technology
Mains level: Not Much
The Union Cabinet has approved the auction of airwaves capable of offering fifth generation, or 5G, telecom services, including ultra-high-speed Internet, and gave its nod for setting up of captive 5G networks by big tech firms.
What is the news?
- The auction of over 72 GHz of the spectrum will be held by July-end.
- Auctions will be held at reserve prices recommended by the sector regulator, Telecom Regulatory Authority of India (TRAI).
- TRAI had earlier recommended about a 39% reduction in the reserve or floor price for the sale of 5G spectrum for mobile services.
What is 5G technology?
- 5G or fifth generation is the latest upgrade in the long-term evolution (LTE) mobile broadband networks.
- It mainly works in 3 bands, namely low, mid and high-frequency spectrum — all of which have their own uses as well as limitations.
Three bands of 5G
(1) Low band spectrum
- It has shown great promise in terms of coverage and speed of internet and data exchange, the maximum speed is limited to 100 Mbps (Megabits per second).
- This means that while telcos can use and install it for commercial cellphones users who may not have specific demands for very high-speed internet, the low band spectrum may not be optimal for the specialized needs of the industry.
(2) Mid-band spectrum
- It offers higher speeds compared to the low band but has limitations in terms of coverage area and penetration of signals.
- Telcos and companies, which have taken the lead on 5G, have indicated that this band may be used by industries and specialized factory units for building captive networks that can be molded into the needs of that particular industry.
(3) High-band spectrum
- It offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
- Internet speeds in the high-band spectrum of 5G have been tested to be as high as 20 Gbps (gigabits per second), while, in most cases, the maximum internet data speed in 4G has been recorded at 1 Gbps.
Where does India stand in the 5G technology race?
- On par with the global players, India had, in 2018, planned to start 5G services as soon as possible, with an aim to capitalize on the better network speeds and strength that the technology promised.
- Indian private telecom players have been urging the DoT to lay out a clear road map of spectrum allocation and 5G frequency bands so that they would be able to plan the rollout of their services accordingly.
- One big hurdle, however, is the lack of flow of cash and adequate capital with some companies due to their AGR dues.
Global progress on 5G
- More than governments, global telecom companies have started building 5G networks and rolling it out to their customers on a trial basis.
- In countries like the US, some companies have taken the lead when it comes to rolling out commercial 5G for their users.
- A South Korean company, which had started researching on 5G technology way back in 2011, has, on the other hand, take the lead when it comes to building the hardware for 5G networks for several companies.

From UPSC perspective, the following things are important :
Prelims level: Diabetes , its types
Mains level: Not Much
Last week, the Indian Council of Medical Research (IMCR) released guidelines for the diagnosis, treatment, and management for type-1 diabetes.
Why such move?
- India is considered the diabetes capital of the world, and the pandemic disproportionately affected those living with the disease.
- Type 1 or childhood diabetes, however, is less talked about, although it can turn fatal without proper insulin therapy.
- Type 1 diabetes is rarer than type 2. Only 2% of all hospital cases of diabetes in the country are type 1.
What is Diabetes?
- Diabetes is a chronic (long-lasting) health condition that affects how your body turns food into energy.
- Most of the food you eat is broken down into sugar (also called glucose) and released into your bloodstream.
- When your blood sugar goes up, it signals your pancreas to release insulin.
What is Type 1 Diabetes?
- Type 1 diabetes is a condition where the pancreas completely stops producing insulin.
- Insulin is the hormone responsible for controlling the level of glucose in blood by increasing or decreasing absorption to the liver, fat, and other cells of the body.
- This is unlike type 2 diabetes — which accounts for over 90% of all diabetes cases in the country — where the body’s insulin production either goes down or the cells become resistant to the insulin.
How lethal diabetes is?
- Type 1 diabetes is predominantly diagnosed in children and adolescents.
- Although the prevalence is less, it is much more severe than type 2.
- Unlike type 2 diabetes where the body produces some insulin and which can be managed using various pills, if a person with type 1 diabetes stops taking their insulin, they die within weeks.
How rare is it?
- There are over 10 lakh children and adolescents living with type 1 diabetes in the world, with India accounting for the highest number.
- Of the 2.5 lakh people living with type 1 diabetes in India, 90,000 to 1 lakh are under the age of 14 years.
- For context, the total number of people in India living with diabetes was 7.7 crore in 2019.
- Among individuals who develop diabetes under the age of 25 years, 25.3% have type 2.
Who is at risk of type 1 diabetes?
- The exact cause of type 1 diabetes is unknown, but it is thought to be an auto-immune condition where the body’s immune system destroys the islets cells on the pancreas that produce insulin.
- Genetic factors play a role in determining whether a person will get type-1 diabetes.
- The risk of the disease in a child is 3% when the mother has it, 5% when the father has it, and 8% when a sibling has it.
- The presence of certain genes is also strongly associated with the disease.

Prelims level: Web and its evolution
Mains level: Not Much
Former Twitter CEO recently announced his vision for a new decentralized web platform that is being called Web 5.0 and is being built with an aim to return “ownership of data and identity to individuals”.
Various versions of Web
- Web 1.0 was the first generation of the global digital communications network. It is often referred to as the “read-only” Internet made of static web-pages that only allowed for passive engagement.
- Web 2.0 was the “read and write” Internet. Users were now able to communicate with servers and other users leading to the creation of the social web. This is the World Wide Web that we use today.
- Web 3.0 is an evolving term that is used to refer to the next generation of Internet – a “read-write-execute” web – with decentralization as its bedrock. It leverages the blockchain technology and will be driven by Artificial Intelligence and machine learning.
- Web 4.0 is not really a new version, but is a alternate version of what we already have. Web needed to adapt to its mobile surroundings. Web 4.0 connects all devices in the real and virtual world in real-time.
What is Web 5.0?
- Web 5.0 is aimed at building an extra decentralized web that puts you in control of your data and identity.
- Simply put, Web 5.0 is Web 2.0 plus Web 3.0 that will allow users to ‘own their identity’ on the Internet and ‘control their data’.
- Both Web 3.0 and Web 5.0 envision an Internet without threat of censorship – from governments or big tech, and without fear of significant outages.
What are the use cases for Web 5.0?
There can be two use cases for how Web 5.0 will change things in the future.
- Control of identity: A digital wallet that securely manages user identity, data, and authorizations for external apps and connections.
- Control over own data: Say, we can grant any music app access to settings and preferences, enabling the app to take our personalized music experience across different music apps.
Try this question from CSP 2022:
With reference to Web 3.0, consider the following statements:
- Web 3.0 technology enables people to control their own data.
- In Web 3.0 world, there can be blockchain based social networks.,
- Web 3.0 is operated by users collectively rather than a corporation.

Prelims level: National e-Vidhan Application (NeVA)
Mains level: Parliamentary efficiency
A delegation of MLAs from Gujarat visited the UP Legislative Assembly to learn about the novel e-Vidhan system for paperless proceedings that has been recently adopted by the UP state assembly.
E-Vidhan System
- The National e-Vidhan Application (NeVA) is a system for digitising the legislative bodies of all Indian states and the Parliament through a single platform.
- It includes a website and a mobile app.
- The house proceedings, starred/unstarred questions and answers, committee reports etc. will be available on the portal.
- Nagaland became the first state to implement NeVA, in March this year.
Significance of NeVA
- There has been a shift towards digitisation in recent years by the government.
- NeVA aims for streamlining information related to various state assemblies, and to eliminate the use of paper in day-to-day functioning.
- PM Modi mentioned the idea of “One Nation One Legislative Platform” in November 2021.
- A digital platform not only gives the necessary technological boost to our parliamentary system, but also connects all the democratic units of the country.
Has this been done elsewhere?
- Himachal Pradesh’s Legislative Assembly implemented the pilot project of NeVA in 2014, where touch-screen devices replaced paper at the tables of the MLAs.
- Though both Houses of Parliament have not gone fully digital yet, governments world over are heading towards embracing the digital mode.
- In December last year, the Government of Dubai became the world’s first government to go 100 percent paperless.
- It announced all procedures were completely digitised.
- This, as per a government statement, would cut expenditure by USD 350 million and also save 14-million-man-hours.
What are the challenges?
- Access to devices and reliable internet and electricity was an issue particularly for legislators representing rural constituencies.
- Lack of training and heightened concerns over security are some more recent issues in the road to digitization.

Scientists have found microplastics — plastic pieces much smaller than a grain of rice — in freshly fallen Antarctic snow for the first time.
What are Microplastics?
- Microplastics are tiny bits of various types of plastic found in the environment.
- The name is used to differentiate them from “macroplastics” such as bottles and bags made of plastic.
- There is no universal agreement on the size of microplastics. It defines microplastic as less than 5mm in length.
- However, for the purposes of this study, since the authors were interested in measuring the quantities of plastic that can cross the membranes and diffuse into the body via the bloodstream.
- Hence they agreed on an upper limit on the size of the particles as 0.0007 millimetre.
Why in news?
- Researchers have found microplastics in the snow samples from the Ross Ice Shelf in Antarctica.

Prelims level: TVS-2M Nuclear Fuel
Mains level: Not Much
Russia has supplied the first batches of more reliable and cost-efficient nuclear fuel over the existing one, the TVS-2M nuclear fuel, to India for the Kudankulam Nuclear Power Plant (KNPP).
What is TVS-2M Nuclear Fuel?
- The TVS-2M FAs contain gadolinium-oxide which is mixed with U-235 enrichments.
- The core does not contain BARs (Burnable Absorbers Rods).
How are they prepared?
- Once the uranium is enriched, it is ready to be converted into nuclear fuel.
- At a nuclear fuel fabrication facility, the UF6, in solid form, is heated to gaseous form, and then the UF6 gas is chemically processed to form uranium dioxide (UO2) powder.
- The powder is then compressed and formed into small ceramic fuel pellets.
- The pellets are stacked and sealed into long metal tubes that are about 1 centimetre in diameter to form fuel rods.
- The fuel rods are then bundled together to make up a fuel assembly.
- Depending on the reactor type, each fuel assembly has about 179 to 264 fuel rods.
- A typical reactor core holds 121 to 193 fuel assemblies.
Benefits offered
- TVS-2M fuel assemblies have a number of advantages making them more reliable and cost-efficient.
- The new fuel has increased uranium capacity – one TVS-2M assembly contains 7.6% more fuel material as compared to UTVS.
- Besides, the special feature of the Kudankulam fuel in particular is the new generation anti-debris filter ADF-2, efficiently protecting fuel assemblies.
- Once the new TVS-2 M fuel is used in the next refuelling, the reactor will start operations with an 18-month fuel cycle.
- It means the reactor, which has to be stopped for every 12 months for removing the spent fuel and inserting the fresh fuel bundles and allied maintenance, will have to be stopped for every 18 months.
Back2Basics: India-Russia Energy Cooperation
- The Soviet Union supplied India with nuclear reactors and fuel when India was denied technologies and was hit with sanctions from the West for its refusal to sign the nuclear non-proliferation treaty (NPT).
- In 1988, the Soviet Union agreed, allegedly without an official deal, to build two nuclear reactors at Kudankulam in Tamil Nadu. The deal was made official in 1992.
- In 2000, Russia and India signed another secret MoU, to cooperate on “peaceful uses” of nuclear energy, and for Russia to supply India with low-enriched uranium fuel for the Tarapur reactor in Maharashtra.
- In 2009, the two countries entered into a major nuclear deal, with Russia agreeing to install four nuclear reactors at Kudankulam in Tamil Nadu, and one in West Bengal.
- Two units at Kudankulam are currently operational, and the third and fourth units are being prepared for installation.
- Russia is also aiding with the ongoing construction of the fifth and sixth units.

- The President of India is elected indirectly by an Electoral College following the system of proportional representation utilizing a single transferable vote system and secret ballots.
- MPs and MLAs vote based on parity and uniformity values.
Electoral College composition-
(1) Legislative Assemblies of the States:
- According to the provision of Article 333, every state’s Legislative Assembly must consist of not less than 60 members but not more than 500 members.
(2) Council of States:
- 12 members are nominated by the President of India based on skills or knowledge in literature, arts, science, and social service to act as the members of the Council of States.
- In total, 238 represent act as representatives from both the States and Union Territories.
(2) House of the People:
- The composition of the House of People consists of 530 members (no exceeding) from the state territorial constituencies.
- They are elected through direct election.
- The President further elects 20 more members (no exceeding) from the Union Territories.
Uniformity in the scale of representation of states
To maintain the proportionality between the values of the votes, the following formula is used:
Value of vote of an MLA= total no. of the population of the particular state/ number of elected MLAs of that state divided by 1000.
Single vote system-
- During the presidential election, one voter can cast only one vote.
- While the MLAs vote may vary state to state, the MPs vote always remain constant.
MPs and MLAs vote balance-
- The number of the total value of the MPs votes must equal the total value of the MLAs to maintain the State and the Union balance.
Quotas:
- The candidate reaching the winning quota or exceeding it is the winner.
- The formula sued is ‘Winning quota total number of poll/ no.of seats + 1’.
Voters’ preference:
- During the presidential election, the voter casts his vote in favor of his first preferred candidate.
- However, in case the first preference candidate does not touch the winning quota, the vote automatically goes to the second preference.
- The first preferred candidate with the lowest vote is eliminated and the votes in his/her favor are transferred to the remaining candidates.
Why need Proportional representation?
- The President of India is elected through proportional representation using the means of the single transferable vote (Article 55(3)).
- It allows the independent candidates and minority parties to have the chance of representation.
- It allows the practice of coalition with many voters under one government.
- This system ensures that candidates who are elected don’t represent the majority of the electorate’s opinion.
Why is President indirectly elected?
If Presidents were to be elected directly, it would become very complicated.
- It would, in fact, be a disaster because the public doesn’t have the absolute clarity of how the president-ship runs or if the candidate fits the profile of a president.
- Another reason why the direct election system isn’t favorable is that the candidate running for the president’s profile will have to campaign around the country with the aid of a political party.
- And, this will result in a massive political instability.
- Moreover, it would be difficult and impossible for the government to hand out election machinery (given the vast population of India).
- This will cost the government financially, and may end up affecting the economy as well.
- The indirect election system is a respectable system for the First Man of India (rightly deserving).
- The system/method of indirect electing of the president also allows the states to maintain neutrality and minimize hostility.

From UPSC perspective, the following things are important :
Prelims level: Fast Radio Burst (FRB)
Mains level: Not Much
In a paper published in Nature, astronomers have reported a fast radio burst (FRB) whose characteristics are different from almost all other FRBs previously detected.
Such news makes us think about alien and extraterrestrial life at the first. Do not get carried away with such thoughts. Its simply a space based phenomena.
Fast Radio Burst (FRB)
- FRBs are super intense, millisecond-long bursts of radio waves produced by unidentified sources in the distant cosmos.
- They were first discovered in 2007 when scientists combed through archival pulsar data.
- Pulsars refer to spherical, compact objects in the universe, which are about the size of a large city but contain more mass than the sun.
- They often look like flickering stars but are not stars.
Why in news?
- The new study in Nature describes FRB 20190520B, first discovered in 2019.
- What makes it different is that unlike many other FRBs, it emits frequent, repeating bursts of radio waves.
- And between bursts, it constantly emits weaker radio waves.
- FRB 190520B is co-located with a compact, persistent radio source and associated with a dwarf host galaxy of high specific star formation.

From UPSC perspective, the following things are important :
Prelims level: Indian Rhino
Mains level: Not Much
The one-horned rhinos of western Assam’s Manas National Park, bordering Bhutan, are expected to have high life expectancy and significant growth in population, the 14th Assam rhino estimation census has revealed.
Indian Rhino
- The Indian rhinoceros also called the greater one-horned rhinoceros and great Indian rhinoceros is a rhinoceros native to the Indian subcontinent.
- It is listed as Vulnerable on the IUCN Red List and Schedule I animal in the Wildlife Protection Act, 1972.
- It once ranged across the entire northern part of the Indian Subcontinent, along the Indus, Ganges and Brahmaputra River basins, from Pakistan to the Indian-Myanmar border.
- Poaching for rhinoceros horn became the single most important reason for the decline of the Indian rhino.
Why in news?
- The 14th Rhino Population Estimation / Census in Kaziranga National Park counted at least 2613 rhinos including calves, a jump of exactly 200 rhinos since the last census conducted in 2018.
- Then at least 2413 Rhinos were counted in the national park.
Threats to Rhinos
- Ground rhino horn is used in traditional Chinese medicine to cure a range of ailments, from cancer to hangovers, and also as an aphrodisiac.
- In Vietnam, possessing a rhino horn is considered a status symbol.
- Due to demand in these countries, poaching pressure on rhinos is ever persistent against which one cannot let the guard down.
Various protection moves
- A rhino reintroduction programme under the Indian Rhino Vision 2020 was started in 2006.
- This entailed the translocation of rhinos from Kaziranga National Park and Pobitora Wildlife Sanctuary besides orphans hand-reared at the Centre for Wildlife Rehabilitation and Conservation at Kaziranga.

From UPSC perspective, the following things are important :
Prelims level: Corvettes
Mains level: Indian navy modernization
The Defence Acquisition Council (DAC) has given the Acceptance of Necessity (AoN) for the procurement of next-generation Corvettes for the Indian Navy at an approximate cost of Rs 36,000 crore.
What is a Corvette?
- A Corvette is the smallest class of naval ships and it falls below the warship class of a frigate.
- These are highly agile ships and are categorised as missile boats, anti-submarine ships, coastal patrol crafts and fast attack naval vessels.
- The word corvette itself is derived from French and Dutch origin.
- During World War II, the term Corvette was used to describe vessels which had anti-submarine roles assigned to them.
- Modern Corvettes can go up to 2,000 tons in displacement which helps in keeping them agile.
What kind of Corvettes does the Indian Navy possess?
- The Indian Navy at present has the Kamorta Class Corvettes, which are also known as Project 28.
- These ships have an anti-submarine role and are manufactured at Garden Reach Shipbuilders and Engineers in Kolkata.
- The four Kamorta Class Corvettes that the Indian Navy possesses are named INS Kamorta, INS Kadmatt, INS Kiltan and INS Kavaratti.
- The first of these was commissioned in 2014 and the last one in 2020.
What new capabilities will the new generation Corvettes have?
- The next-generation Corvettes will be manufactured for various roles like surveillance missions, escort operations, deterrence, surface action group operations, search and attack and coastal defence.
- It is worth noting that these roles will be in addition to the anti-submarine roles being already performed by the existing Corvettes in the Navy.
- Corvettes will be constructed based on new in-house design of the Indian Navy using latest technology of ship buildings.
- They would contribute to further the government’s initiative of Security and Growth for all in the region (SAGAR).

From UPSC perspective, the following things are important :
Prelims level: Dostarlimab
Mains level: NA
A trial on 18 colorectal cancer patients in the US found that cancer could be treated without chemotherapy or surgery. The world is sitting up and taking note of Dostarlimab, which has been called a wonder drug.
What is Dostarlimab?
- Dostarlimab is an experimental drug. It contains laboratory-produced molecules.
- It acts as substitute antibodies. It is sold under the brand name Jemperli.
- It was approved for medical use in the United States and the European Union in 2021.
- Its side-effects include vomiting, joint pain, itching, rash, fever etc.
What are the findings?
- The trial showed that immunotherapy alone – without any chemotherapy, radiotherapy, or surgery that have been staples of cancer treatment.
- It could completely cure the patients with a particular kind of rectal cancer called ‘mismatch repair deficient’ cancer”.
- All 12 patients had completed the treatment and were followed for six to 25 months after.
- No cases of progression or recurrence had been reported during the follow-up.
- The response too was rapid, with symptoms resolving in 81% of the patients within nine weeks of starting the therapy.
Is Dostarlimab actually very effective?
- Dostarlimab is not a new drug but a combination of drugs that are already approved for use in immunotherapy.
- There is a possibility that Dostarlimab may improve the outcome and survival rate in rectal cancer patients but to say it as a magic drug for cancer is completely going overboard.
How does this drug cure?
- PD1 is a protein that regulates immune function and can sometimes keep T cells from killing cancer cells.
- The therapy in the trial used PD1 blockades, allowing T cells to kill cancer cells.
- ‘Mismatch repair deficient’ cancer is most common among colorectal, gastrointestinal, and endometrial cancers.
- Patients suffering from this condition lack the genes to correct typos in the DNA that occur naturally while cells make copies.
- Immunotherapy belongs to a category called PD1 blockades that are now recommended for the treatment of such cancers rather than chemotherapy or radiotherapy.
Will Indian patients get access to the drug?
- At present, Indian doctors seem to be generally wary of prescribing Dostarlimab for their patients.
- Experts have termed as optimistic the findings of an ongoing trial—a group of rectal cancer patients showed no signs of a tumour after taking the drug for six months.
- None of the participants reported any severe side-effects either.
- Yet, doctors say they want to assess the duration of the response.
What do we know about the clinical trial?
- Cancer was treated in all the patients and could not be detected by physical examination, endoscopy, positron emission tomography, or magnetic resonance imaging.
- Thus, there is a thought that cancer can be treated without chemotherapy or surgery.
Is it too early to celebrate?
- Cancer specialists said initial signals show how precision medicine is building the future but they need to test more patients from different areas and other types of cancers.
- The combination of drugs was administered to a small number of patients and for a specific type of cancer.

From UPSC perspective, the following things are important :
Prelims level: Features of UPI
Mains level: Not Much
The RBI has proposed to allow the linking of credit cards with the Unified Payments Interface (UPI).
Integrating Credit Cards to UPI
- The integration will first begin with the indigenous RuPay credit cards.
- Both the RuPay network and UPI are managed by the same organisation – the National Payments Corporation of India (NPCI).
What is UPI?
- UPI is an instant real-time payment system developed by National Payments Corporation of India (NPCI) facilitating inter-bank transactions.
- The interface is regulated by the Reserve Bank of India and works by instantly transferring funds between two bank accounts on a mobile platform.
Why such move?
- The linkage of UPI and credit cards could possibly result in credit card usage zooming up in India given UPI’s widespread adoption.
- The integration also opens up avenues to build credit on UPI through credit cards in India, where in the last few years, a number of startups like Slice, Uni, One etc. have emerged.
- The move could also be a push to increase adoption by banking on UPI’s large user base.
- So far, UPI could only be linked to debit cards and bank accounts.
- This will provide additional convenience to the users and enhance the scope of digital payments.
What could be the hurdles?
- There are some regulatory areas that would have to be addressed before the linkage happens.
- For instance, it is not clear how the Merchant Discount Rate (MDR) will be applied to UPI transactions done through credit cards.
- UPI and RuPay attract zero-MDR, meaning that no charges are applied to these transactions, which is a key reason behind the prolific adoption of UPI both by users and merchants.
- The norm has faced pushback from the payments industry.
- It has argued that it limits the aggregators’ ability to invest in and maintain the financial infrastructure of the payment ecosystem that they have built.
- Applicability of zero-MDR on UPI could also be a reason why other card networks such as Visa and Mastercard may not have been onboarded to UPI for credit cards yet.
Note: MDR is a fee that a merchant is charged by their issuing bank for accepting payments from their customers via credit and debit cards.
What is the big picture?
- UPI has become the most inclusive mode of payment in India with over 26 crore unique users and five crore merchants on the platform.
- The progress of UPI in recent years has been unparalleled.
- Many other countries are engaged with us in adopting similar methods in their countries.
- In May, UPI processed 5.95 billion transactions worth over Rs 10 trillion, a record high since its launch in 2016.
- NPCI is looking to soon process a billion transactions a day.
Try this PYQ from CSP 2017:
Q.Which one of the following best describes the term “Merchant Discount Rate” sometimes seen in news?
(a) The incentive given by a bank to a merchant for accepting payments through debit cards pertaining to that bank
(b) The amount paid back by banks to their customers when they use debit cards for financial transactions for purchasing goods or services
(c) The charge to a merchant by a bank for accepting payments from his customers through the bank’s debit cards
(d) The incentive is given by the Government to merchants for promoting digital payments by their customers through Point of Sale (PoS) machines and debit cards

From UPSC perspective, the following things are important :
Prelims level: CiSS Application
Mains level: Child rights issue
The National Commission for the Protection of Child Rights (NCPCR) has launched a “CiSS application” under the Baal Swaraj portal to help in the rehabilitation process of Children in Street Situations (CiSS).
CiSS Application
- The CiSS application is used for receiving data of children in street situations from all the states and union territories, tracking their rescue and rehabilitation process.
- The initiative is taken under the direction of the Supreme Court of India.
- The program embodies Article 51 (A) of the Constitution of India, as it provides a platform to the public and organizations catering to the welfare of the children to report any child in need of assistance.
- The platform serves to collect data and report to the District Child Protection Officer (DCPO) for them to take necessary action.
- It also provides a platform for professionals and organizations to provide any help that they can to children in need.
- Help can be provided in the form of open shelters, counselling services, medical services, sponsorships, de-addiction services, education services, legal/paralegal services, volunteering etc.
Its working framework
- It categorizes any child under ‘Children in Street Situation’ if the child is living on the streets alone, living on the streets during the day, or living on the streets with the family.
- The root cause of this phenomenon is the migration of families from rural to urban areas in search of a better standard of living.
How does it work?
It follows six stages framework for the rehabilitation of children.
- Collection of the child’s details, which is accomplished through the portal.
- Social Investigating Report (SIR)e. investigating the child’s background. This is done under the supervision of the District Child Protection Unit (DCPU) by the District Child Protection Officer (DCPO) by conversing and counselling the child.
- Formulating an Individual Care Plan (ICP) for the child.
- Child Welfare Committee (CWC) based on the SIR submitted to the CWC.
- Allocating the schemes and benefits that the beneficiary can avail of.
- A checklist is made for the evaluation of the progress i.e. (Follow Ups).
