GS Paper: GS3

  • Enforcing the Single-Use Plastic Ban

    A ban on the use of single-use plastics that was notified by the Union Environment Ministry on August 2021 came into effect on July 1 this year.

    What is the news?

    • The national and State-level control rooms would be set up to check illegal manufacture, import, stocking, distribution, sale and use of banned single use plastic items.
    • The Plastic Waste Management Amendment Rules, 2021, will also prohibit manufacture, import, stocking, distribution, sale and use of plastic carry bags.
    • This is for plastics having thickness less than 120 microns with effect from December 31, 2022.

    What is Single-Use Plastic?

    • The Centre defines it as an object made of plastic that is intended to be used “only once” before being disposed off or recycled.
    • Single-use plastic items such as these had “low utility and high littering potential,” it noted.

    What is now included in SUPs?

    • For the purposes of the ban, there is a list of 21 items that come under the definition of single-use plastic including ear buds with plastic sticks, plastic sticks for balloons, plastic flags, candy sticks, ice-cream sticks, thermocol for decoration etc.
    • It also includes plates, cups, glasses, cutlery such as forks, spoons, knives, straw, trays, wrapping or packing films around sweet boxes, invitation cards, and cigarette packets, plastic or PVC banners less than 100 microns, stirrers.
    • These objects were listed by the Environment Ministry in August when it notified the Plastic Waste Management Amendment Rules, 2021.

    How will the ban be implemented?

    • So far 32 States/UTs have reportedly constituted a dedicated Task Force to eliminate the use of single-use plastics.
    • Of these 14 states/UTs and 12 Central Ministries, as of March, had developed action plans describing how they would be enforcing this.
    • A few States, for example Maharashtra, already have legislation banning the manufacture and storage of such plastic.
    • But implementing it wasn’t always successful as there was regular supply from States where such bans were not in force.
    • An all-India ban, it’s hoped, would make enforcement more effective.

    Penal provisions

    • According to the Environment Protection (EP) Act, violating the ban could invite “punitive action”.
    • Manufacturers and distributors of single-use plastic goods were directed to have zero inventory by June 30.
    • The EP Act says that violating the ban could invite a five-year imprisonment and a fine of upto â‚č1 lakh, or both.
    • If the violations are repeated, it could mean additional fines up to â‚č5000 for each day.
    • There are different penalties for companies, organisations, and government departments under the EP Act.

    What is the history of the single use plastic ban in India?

    • The Environment Ministry told the Rajya Sabha last July of its plan to phase out some categories of single use plastic by 2022.
    • A draft outlining the manner in which the ban was to be implemented was issued in March and involved amending the PWM Rules, 2016.
    • Before the amendments came into force, the Rules only prohibited the manufacture, import, stocking, distribution, sale and use of carry bags and plastic sheets less than 50 microns in thickness in the country.
    • There is a ban on sachets using plastic material used for storing, packing or selling gutkha, tobacco and pan masala.
    • Since October 2021, there is a ban on carry bags made of virgin or recycled plastic less than 75 microns as opposed to 50 microns under the earlier version of the rules.

    Is there popular support for the ban?

    • The All India Plastic Manufacturers Association has said that the ban would shutter 88,000 units in the plastic manufacturing business.
    • These employ close to a million people and contribute to exports worth â‚č25,000 crore.
    • Fast Moving Consumer Goods companies (FMCG) would be severely affected by the the ban due to their dependence on plastic straws, plates.
    • Their replacements, industry representatives say, are available but cost much more than their plastic alternatives.
    • There is also limited capacity in India to provide biodegradable replacements.

    What is the environmental damage from SUPs?

    • Unlike thicker and denser plastic material, single-use plastic objects being light and flexible are less amenable to being recycled.
    • While 99% of plastic is recycled, they constitute heavier plastics that are likely to be collected by ragpickers and plastic waste recyclers.
    • Single use plastics do not provide an incentive enough for the effort needed to collect them and hence they lie around, leach their toxins into the soil and cause environmental damage in both land and sea.

  • What is the Large Hadron Collider (LHC)?

    The world’s most powerful particle collider, the Large Hadron Collider (LHC), will begin smashing protons into each other at unprecedented levels of energy beginning July 5.

    What is the LHC?

    • The Large Hadron Collider is a giant, complex machine built to study particles that are the smallest known building blocks of all things.
    • Structurally, it is a 27-km-long track-loop buried 100 metres underground on the Swiss-French border.
    • In its operational state, it fires two beams of protons almost at the speed of light in opposite directions inside a ring of superconducting electromagnets.
    • The LHC’s second run (Run 2) began in 2015 and lasted till 2018. The second season of data taking produced five times more data than Run 1.
    • The third run will see 20 times more collisions as compared to Run 1.

    How does it work?

    • The magnetic field created by the superconducting electromagnets keeps the protons in a tight beam and guides them along the way as they travel through beam pipes and finally collide.
    • Just prior to collision, another type of magnet is used to ‘squeeze’ the particles closer together to increase the chances of collisions.
    • The particles are so tiny that the task of making them collide is akin to firing two needles 10 km apart with such precision that they meet halfway.

    Extreme conditions involved

    • Since the LHC’s powerful electromagnets carry almost as much current as a bolt of lightning, they must be kept chilled.
    • The LHC uses a distribution system of liquid helium to keep its critical components ultracold at minus 271.3 degrees Celsius, which is colder than interstellar space.
    • Given these requirements, it is not easy to warm up or cool down the gigantic machine.

    What is the latest upgrade?

    • Three years after it shut down for maintenance and upgrades, the collider was switched back on this April.
    • This is the LHC’s third run, and it will operate round-the-clock for four years at unprecedented energy levels of 13 tera electron volts.

    Note: A TeV is 100 billion, or 10-to-the-power-of-12, electon volts. An electron volt is the energy given to an electron by accelerating it through 1 volt of electric potential difference.

    Targets this year

    • It now aims to be delivering 1.6 billion proton-proton collisions per second.
    • The last time, the proton beams will be narrowed to less than 10 microns — a human hair is around 70 microns thick — to increase the collision rate.
    • ATLAS is the largest general purpose particle detector experiment at the LHC.
    • The Compact Muon Solenoid (CMS) experiment is one of the largest international scientific collaborations in history, with the same goals as ATLAS, but which uses a different magnet-system design.

    Previous runs & ‘God Particle’ discovery

    • Ten years ago, in 2012, scientists at CERN had announced to the world the discovery of the Higgs boson or the ‘God Particle’ during the LHC’s first run.
    • The discovery concluded the decades-long quest for the ‘force-carrying’ subatomic particle, and proved the existence of the Higgs mechanism, a theory put forth in the mid-sixties.
    • This led to Peter Higgs and his collaborator François Englert being awarded the Nobel Prize for physics in 2013.
    • The Higgs boson and its related energy field are believed to have played a vital role in the creation

  • Species in news: Chenkurinji

    This newscard is an excerpt from the original article published in The Hindu.

    Chenkurinji

    • Chenkurinji (Gluta travancorica) is a species endemic to the Agasthyamala Biosphere Reserve.
    • Belonging to the Anacardiaceae family, the tree was once abundant in the hills on the southern parts of the Aryankavu Pass in Kerala’s Kollam district.
    • The Shendurney Wildlife Sanctuary derives its name Chenkurinji (Gluta travancorica), a species endemic to the Agasthyamala Biosphere Reserve.

    Why in news?

    • It is very susceptible to climate change and the present condition of the species is quite bad with low regeneration performance.
    • Though there are seemingly enough number of the tree, most are not productive, generating a negative trend in its population.
    • The majority of the trees is old with poor flowering and fruiting rates.
    • Though the flowering usually happens in January, of late, the species has reported a tendency to extend the process due to climate change.

    Significance of Chenkurinji

    • It is reported to have medicinal properties and is used to lower blood pressure and treat arthritis.

  • The inflation tightrope

    Context

    The Indian economy has been hit by inflationary shocks of late.

    Inflation story so far

    • RBI mandate: The inflation target of the Reserve Bank of India is 4 per cent, with a band of 2 per cent on either side.
    • Inflation was at or above the upper threshold of 6 per cent since the beginning of this year.
    • Only after inflation hit 7 per cent did the RBI raise the repo rate.
    • Increase in interest rate: The RBI has raised the cost of borrowing (by 90 basis points so far), with a promise of more to come.
    • Fuel taxes reduced: The central government has cut fuel taxes with alacrity, and has banned the export of certain items.

    Role of monetary authorities

    • Monetary authorities raise interest rates if inflation is above the preferred target, and vice versa.
    • What should be the interest rate? Interest rates should rise more than inflation so the “real” interest rates rise, causing a compression in demand (and a fall in economic activity), which in turn will reduce inflation.
    • The RBI embraced this idea. In 2016, an independent monetary policy committee was constituted.

    Effects of global inflation

    • Some part of inflation is coming from abroad is an added complication.
    • Outflow of fund: There has also been a steady outflow of foreign funds from the stock market.
    • Depreciation of rupee: This could cause the rupee to depreciate, in turn, raising the prices of imported goods thereby adding to the inflationary woes.

    Two ways in which the Indian economy is different

    1] Role of agriculture in Indian economy

    • India’s non-food and non-oil components of the consumer price index CPI are about 47 per cent.
    •  In comparison, for the ECB, it is less than one-third of the CPI.
    • Of course, the RBI has no control over international prices of food and oil, so it must squeeze less than 50 per cent of the domestic economy to lower inflation.
    • The real interest rise works through demand compression.
    • But the problem is on the supply side.
    • Also, as compared to the RBI, the ECB would suffer a lower rise in inflation, and has a larger menu on which to apply demand compression.

    2] Exchange rate and its effect on output

    • Until the 1970s, the accepted wisdom was that an economy had to achieve both internal balance and external balance.
    • Internal balance consisted of full employment and low inflation using monetary and fiscal policies.
    • Over time, the internal balance has come to mean, from a policy perspective, low inflation, since “the market” will ensure full employment.
    • External balance required a balanced current account over some horizon (“don’t get too much into foreign debt”), by using, for example, the exchange rate.
    • For the OECD countries, the external balance was not a constraint any longer, since they had made their currencies fully convertible, and international capital flows were unrestricted.
    • But this is not the case with India.
    • If it were so, no one would be interested in discussing the country’s foreign exchange reserves, because these could be generated instantaneously by exchanging the domestic currency for foreign exchange.

    India’s foreign reserves and its impact on competitiveness of Indian products

    • Until 2020, India had seen massive portfolio capital inflows when OECD interest rates were low, and its current account deficits were financed by foreign reserves.
    • But portfolio inflows can, and do, reverse themselves.
    • FII inflows also contribute to India’s lack of competitiveness.
    • The RBI bought foreign exchange (with rupees).
    • But fearing this would stoke inflation, it sold government bonds, and removed the excess liquidity.
    • This “sterilised intervention” saw the RBI’s foreign exchange assets going up, matched by a reduced holding of government bonds.
    • Thus, India’s foreign exchange reserves were not its “own”— there were liabilities against it.
    • India’s Dutch Disease: The RBI could have let the rupee appreciate or have accumulated foreign reserves.
    • It chose an intermediate solution — a mix of an appreciation and accumulation of reserves.
    • The appreciation caused by inflows reduced international competitiveness for Indian products.
    • In effect, we had our own episode of the “Dutch Disease”.

    Way forward

    • As the RBI raises interest rates, outflows will possibly slow down with the rupee appreciating.
    • That is not good for external balance.
    •  It is easy to see that inflation targeting could be at odds with external balance.

    Conclusion

    If inflation does prove stubborn, and fighting inflation is all that the authorities in India worry about, we could see an external crisis.

    Back2Basics: What is Dutch Disease?

    • Dutch disease is an economic term for the negative consequences that can arise from a spike in the value of a nation’s currency.
    • It is primarily associated with the new discovery or exploitation of a valuable natural resource and the unexpected repercussions that such a discovery can have on the overall economy of a nation.
    • Symptoms include a rising currency value leading to a drop in exports and a loss of jobs to other countries.

  • Towards a single low tax regime

    Context

    The introduction of a uniform GST was a watershed moment in India since the country’s earlier regime of taxes and cesses. However, GST is still a complicated tax regime with different slabs.

    Unified single tax

    • Empirical data from across the world on the benefits of a unified single tax is incontrovertible
    • This needs bold and clear reformist thinking at the political level.
    • Imposing a high GST in some areas does not make sense.
    • ‘Sin’ taxes are at cross purposes with the government’s policy of generating growth and creating jobs under ‘Make in India’.
    • High taxes on air-conditioners, air conditioned restaurants, chocolates and luxury cars create an economic ripple effect downstream, in a complex web of businesses that have symbiotic relationships.
    • The effect finally reaches down to the bottom of the employment pyramid.
    • Distrust between State and centre: There is distrust between the States and the Centre on revenue sharing.
    • There is also anger at the Centre for riding roughshod over the States’ autonomy and disregarding the federal structure.

    Multiple rates: A major shortcoming in the structure of GST

    • One of the most important shortcomings in the structure of GST is multiple rates.
    • The committee headed by the Chief Economic Adviser estimated the tax rate at 15-15.5 per cent.
    • It further recommended that in keeping with growing international practice, India should strive towards a single rate in the medium-term to facilitate administrative simplicity and compliance, but in the immediate context, it should have a three-tier structure (excluding zero).
    • The structure finally adopted was to have four rates of 5, 12, 18, and 28 per cent besides zero, though almost 75 per cent of the revenues accrue from the 12 and 18 per cent slabs.
    • Why single rate structure? The reasons for adopting a single rate structure in most countries are:
    • To have a simple tax system,
    • To prevent misclassifications and litigations arising therefrom,
    • To avoid an inverted duty structure of taxes on inputs exceeding those on outputs requiring detailed scrutiny and refunds.
    • Why multiple rates? The main reason for rate differentiation is equity.
    • But it is argued that this is an inefficient way of targeting benefits for the poor. 
    • Although the exempted and low-rated items are consumed relatively more by the poor, in absolute terms, the consumption may be more by the rich.

    Way forward

    • Move people up the value chain: The plan must be to figure out how to rev up the economy by making the rich and upper middle class spend and move more people up the value chain instead of designing a tax system that keeps these products out of the new consumer class’s reach.
    • The same lack of logic applies to taxes on wine, rum and beer, which generate large-scale employment and are the backbone of grape and sugarcane farming and the cocoa industry.
    • In the automobile sector, the GST on electric cars, tractors, cycles, bikes, low-end and luxury cars ranges anywhere from 5% to 50%.
    • The sale of automobiles is the barometer of an economy.
    • Single tax slab: A directive to the bureaucracy is necessary to come up with just two categories: goods eligible for zero tax and goods that will fall under a single rate, say 10% or 12%.
    • Then there are items that are exempt from GST.
    • Bring fuels under GST:  Petrol, diesel, aviation turbine fuel are not under the purview of GST, but come under Central excise and State taxes.
    • A single low tax regime will ensure compliance, widen the tax net, improve ease of doing business, boost the economy, create jobs, increase tax collections and reduce corruption

    Conclusion

    The Finance Minister should take a cue from the Prime Minister, who hinted at major reforms in the aftermath of COVID-19, and do away with all the confusing tax slabs in one fell swoop.

  • Why rice and wheat bans aren’t the answer to inflation

    Context

    There are reports suggesting that the government is mulling a ban on rice exports to tame inflation.

    Background

    • This is surely not the first time an attempt is being made to ban wheat and rice exports.
    • It was also done in 2007-08, in the wake of the global financial crisis.
    • Perhaps government will also impose stocking limits on traders for a host of commodities, suspend futures trading in food items, and even conduct income tax raids on traders of food.

    Issues in India’s rice export strategy

    • Highest ever volume: India exported the highest-ever volume of 21 million metric tonnes (MMT) of rice in 2021-22 (FY22) in a global market of about 51.3 MMT, which amounts to about 41 per cent of global exports.
    • Reduces price: Such large volumes of rice exports brought down global prices of rice by about 23 per cent in March (YoY), when all other cereal prices, be it wheat or maize, were going up substantially in global markets.
    • In fact, in FY22, the unit value of exports of common rice was just $354/tonne, which was lower than the minimum support price (MSP) of rice.
    • Below MSP buying or leakage from PMGKAY: This meant that rice exporters were either buying rice (paddy) from farmers and millers at below the MSP or that quite a substantial part of rice was given free under the PM Garib Kalyan Ann Yojana (PMGKAY) was being siphoned away for exports at prices below MSP.
    • Artificial competitive advantage: Free electricity for irrigation in several states, most notably Punjab, and highly subsidised fertilisers, especially urea, create an artificial competitive advantage for Indian rice in global markets.
    • Suggestion: This is a perfect case for “optimal export tax” — not a ban — on rice exports.
    • If we can’t raise the domestic price of urea, which is long overdue, we should at least recover a part of the urea subsidy from rice exports by imposing an optimal export tax.

    Why export ban on wheat and rice is not a solution

    • Small contribution of cereals in inflation: In May, the consumer price index (CPI) inflation was 7.04 per cent (YoY). The cereals group as a whole contributed only 6.6 per cent to this inflation.
    • Within that, wheat, other than through PDS, contributed just 3.11 per cent and non-PDS rice contributed 1.59 per cent.
    • So, by imposing a ban on wheat and rice exports, India can’t tame its inflation as more than 95 per cent of CPI inflation is due to other items.
    • Interestingly, inflation in vegetables contributed 14.4 per cent to CPI inflation, which is more than three times the contribution of rice and wheat combined. And within vegetables, tomatoes alone contributed 7.01 per cent.
    • What all this indicates is that agri-trade policies need to be more stable and predictable, rather than a result of knee-jerk reactions.
    • Irresponsible behaviour: Export bans on food items also show somewhat irresponsible behaviour at the global level, unless there is some major calamity in the country concerned.
    • The recently concluded WTO ministerial meeting as well as the G-7 meet expressed concerns about food security in vulnerable nations.

    Way forward

    • Efficient value chain and processing facilities: In commodities like vegetables, most of which are largely perishable, we need to build efficient value chains and link these to processing facilities.
    • The same would go for onions, which often bring tears to kitchen budgets when prices shoot up.
    • A switch to dehydrated onion flakes and onion powder would be the answer.
    • Our food processing industry, especially in perishable products, is way behind the curve compared to several Southeast Asian nations.

    Conclusion

    If India wants to be a globally responsible player, it should avoid sudden and abrupt bans and, if need be, filter them through transparent export taxes to recover its large subsidies on power and fertilisers.

  • After Ukraine, the new energy disorder

    Context

    Our long-standing “friend“ (Russia) is now in the bad books of our other friends (the US and Europe) and in a deepening relationship with our adversary (China). The Gulf countries are crucial for our energy security but Russia has replaced them as our principal supplier

    How Ukraine war is changing the energy policies

    • Six months back before the start of the Ukrainian conflict, there was a deepening sense that fossil fuels and the industry built around them were in terminal decline.
    • After the Ukraine war began, the petroleum market is tight and prices are ratcheting up.
    • Oil prices are close to $120/bbl and gas prices have jumped 500 per cent year on year in Europe.
    • The regulatory constraints on petroleum exploration and distribution infrastructure have been eased and several countries have removed the output limits on thermal power generation and reopened the coal mines that were closed.
    • The share prices of the oil majors are trading at multi-year highs.

    Three issues that influences India’s energy policy

    1] Long term implications of buying oil from Russia

    • India is now a major purchaser of Russian crude.
    • Last month, it reportedly purchased an average of 1.2 mbd.
    • If this figure is correct, Russia is now our largest provider of crude oil surpassing Saudi Arabia and Iraq.
    • The reason for this ramp-up is the price discount offered by Russia.
    • The decision is driven by good economics and energy security.
    • The Western world does not, however, see it this way.
    •  The question does arise: What might be the medium to longer-term implications of our “support” to Russia on relations with Capitol Hill, the UK and the European Commission?

    2] Increased economic and energy ties of Russia and China

    •  Russia and China have, for long, shared the view that the US is their biggest security threat.
    • China also increased the purchase of Russian oil and gas.
    • This tightened economic and energy embrace has implications for India.
    • Several questions will need to be addressed.
    • Russia’s role in India-China conflict: How might a post-Ukraine weakened Russia that is in hock to China respond to India in the event matters deteriorate on our border with China?
    • Will they be reliable providers of crude oil, military equipment, minerals, and metals essential for our green transition?
    • Will they be politically autonomous or client states?

    3] Important role of the Gulf states

    • The Ukrainian crisis has forced a presidential u-turn. Later this month, President Biden will visit Saudi Arabia.
    • Several other European leaders will also beat a path to the Gulf, all in the hope of extracting a promise of higher production to lower oil prices and some to negotiate gas supply deals.
    • India needs the Gulf producers for supply security. But it also wants oil prices to come down.
    •  The position of these producers in the reordered post-Ukraine energy landscape is, therefore, of relevance.
    • Will they respond positively to the courtship of Russia/China, move back into the Western fold, or stay outside both orbits, neutral and opportunistic?
    • The answer will bear on India’s energy security.

    Way forward

    • Integrated energy policy: What we need is a mechanism for the development and execution of an integrated energy policy.
    • This is because currently there is no executive authority responsible for energy.
    • There are ministries responsible for components of energy policy but no formal mechanism for aligning their separate approaches.
    • The Ukraine war has disrupted the existing energy order.
    • The new energy (dis) order has created fissures that impact our national security, economic growth, trade, clean energy supply lines, transfer of technology and international relations.
    • We cannot, therefore, afford to continue with our existing siloed approach.

    Conclusion

    The Ukrainian crisis has radically altered the contours of the global energy landscape and created a tangle of relationships and issues for India. To smoothen this tangle and address the issues India should adopt “a whole of the system” approach to energy policy.

  • Functioning of the National Investigation Agency (NIA)

    The National Investigation Agency (NIA) has taken over the probe into the terrible beheading of a person in Udaipur by Jihadi radicalists.

    What is the NIA?

    • Headquartered in Delhi, the NIA has its branches in Hyderabad, Guwahati, Kochi, Lucknow, Mumbai, Kolkata, Raipur, Jammu, Chandigarh, Ranchi, Chennai, Imphal, Bengaluru and Patna.
    • It is a central agency mandated to investigate all the offences affecting:
    1. Sovereignty, security and integrity of India
    2. Friendly relations with foreign states
    3. Offences under the statutory laws enacted to implement international treaties, agreements, conventions and resolutions of the United Nations, its agencies and other international organisations
    • The offense include terror acts and their possible links with crimes like smuggling of arms, drugs and fake Indian currency and infiltration from across the borders.
    • The agency has the power to search, seize, arrest and prosecute those involved in such offences.

    When did the NIA come into being?

    • In the wake of the 26/11 Mumbai terror attack in November 2008, which shocked the entire world, the then United Progressive Alliance government decided to establish the NIA.
    • In December 2008, former Union Home Minister P. Chidambaram introduced the National Investigation Agency Bill.
    • The agency would deal with only eight laws mentioned in the schedule and that a balance had been struck between the right of the State and duties of the Central government to investigate the more important cases.
    • The agency came into existence on December 31, 2008, and started its functioning in 2009.
    • Till date, the NIA has registered 447 cases.

    What are the scheduled offences?

    The list includes the

    1. Explosive Substances Act,
    2. Atomic Energy Act,
    3. Unlawful Activities (Prevention) Act,
    4. Anti-Hijacking Act,
    5. Suppression of Unlawful Acts against Safety of Civil Aviation Act,
    6. SAARC Convention (Suppression of Terrorism) Act,
    7. Suppression of Unlawful Acts Against Safety of Maritime Navigation and Fixed Platforms on Continental Shelf Act,
    8. Weapons of Mass Destruction and their Delivery Systems (Prohibition of Unlawful Activities) Act and
    9. Relevant offences under the Indian Penal Code, Arms Act and
    10. Information Technology Act
    • In September 2020, the Centre empowered the NIA to also probe offences under the Narcotic Drugs and Psychotropic Substances Act that are connected to terror cases.

    How wide is NIA’s jurisdiction?

    • The law under which the agency operates extends to the whole of India.
    • It also applies to:
    1. Indian citizens outside the country;
    2. Persons in the service of the government wherever they are posted;
    3. Persons on ships and aircraft registered in India wherever they may be;
    4. Persons who commit a scheduled offence beyond India against the Indian citizen or affecting the interest of India.

    How does the NIA take up a probe?

    • As provided under Section 6 of the Act, State governments can refer the cases pertaining to the scheduled offences registered at any police station to the Central government (Union Home Ministry) for NIA investigation.
    • After assessing the details made available, the Centre can then direct the agency to take over the case.
    • State governments are required to extend all assistance to the NIA.
    • Even when the Central government is of the opinion that a scheduled offence has been committed which is required to be investigated under the Act, it may, suo motu, direct the agency to take up/over the probe.

  • Researchers found gene regulating Nitrogen absorption in Plant

    Researchers led by those from the National Centre of Biological Sciences, Tata Institute of Fundamental Research, Bengaluru (NCBS-TIFR), have found a new pathway that regulates nitrate absorption in plants.

    Nitrogen in plant nutrition

    • Nitrogen is one of the most important macronutrients needed for development of a plant.
    • It is a part of chlorophyll, amino acids and nucleic acids, among others.
    • It is mostly sourced from the soil where it is mainly absorbed in the form of nitrates and ammonium by the roots.
    • Nitrates also play a role in controlling genome-wide gene expression that in turn regulates root system architecture, flowering time, leaf development, etc.
    • Thus, while a lot of action takes place in the roots to absorb and convert nitrogen into useful nitrates, the absorbed nitrates in turn regulate plant development apart from being useful as a macronutrient.

    What is MADS27?

    • The gene MADS27, which regulates nitrate absorption, root development and stress tolerance, is activated by the micro-RNA, miR444, therefore offers a way to control these properties of the plant.
    • The researchers studied this mechanism in both rice (monocot) and tobacco (dicot) plants.

    Regulatory switches

    • In addition to this route, several gene regulatory switches that regulate nitrate absorption and root development, such as the micro-RNA, miR444, are known in monocot plants, such as rice.
    • The micro-RNA ‘miR444’ is specific to monocots.
    • When this is not made, its target, MADS27, is produced in higher abundance, and it improves biosynthesis and transport of the hormone auxin, which is key for root development and its branching.
    • This regulatory miR444 switch is known to turn off at least five genes called MADS box transcription factor genes.
    • The speciality of the MADS box transcription factors is that they function like switch boxes of their own.
    • They bind to their favourite specific DNA sequences and they switch the neighbouring genes “on.”

    Why is the discovery important?

    • Presence of nitrates is important for the plant development and also for grain production.
    • However, the overuse of nitrates in fertilizers, for instance, can lead to the dumping of nitrates in the soil which leads to accumulation of nitrates in water and soil.
    • This accumulation adds to soil and water pollution and increased contribution to greenhouse gases.
    • Also, since the whole process of nitrate absorption takes place in the roots, a well-developed root system is needed for this to take place optimally.
    • At one level, it is known that the hormone auxin is responsible for well-developed roots across all plants.
    • A number of genes are known to help with auxin production, improved nitrate transport and assimilation in plants.

    Significance of MADS27

    • The MADS27 transcription factor has a three-pronged effect on the plant.
    • First, it regulates nitrate absorption by switching “on” proteins involved in this process.
    • Second, it leads to better development of the roots by regulating auxin hormone production and transport.
    • Finally, and somewhat surprisingly to the researchers, it helps in the abiotic stress tolerance by keeping the main stress player proteins “on.”

  • Mayurbhanj’s superfood ‘Ant Chutney’

    The Kai Chutney made from Red Ants by the tribals of Mayurbhanj district in Odisha are seeking a Geographical Indications (GI) tag.

    Ant Chutney

    • Despite this, weaver ants are popular among the people, mostly of the tribes,
    • This food item, rich in proteins, calcium, zinc, vitamin B-12, iron, magnesium, potassium, sodium, copper, fibre and 18 amino acids, is known to boost the immune system and keep diseases at bay.
    • Applied under food category, the GI tag will help develop a structured hygiene protocol in the preparation of Kai chutney for standard wider use.
    • Geographical Indications labels enhance the reputation and value of local products and support local businesses.

    How is the Chutney prepared?

    • Weaver ants, Oecophylla smaragdina, are abundantly found in Mayurbhanj throughout the year.
    • They make nests with leaves of host trees.
    • The chutney is prepared by mixing and grinding salt, ginger, garlic and chilly and is sold by tribal people in rural markets.

    Back2Basics:  Geographical Indication

    • A GI is a sign used on products that have a specific geographical origin and possess qualities or a reputation that are due to that origin.
    • Nodal Agency: Department for Promotion of Industry and Internal Trade (DPIIT), Ministry of Commerce and Industry
    • India, as a member of the World Trade Organization (WTO), enacted the Geographical Indications of Goods (Registration and Protection) Act, 1999 w.e.f. September 2003.
    • GIs have been defined under Article 22 (1) of the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) Agreement.
    • GI is granted for a term of 10 years in India. As of today, more than 300 GI tags has been allocated so far in India (*Wikipedia).
    • The tag stands valid for 10 years.
