GS Paper: GS3

  • Places in news: Lemru Elephant Reserve

    The proposed Lemru Elephant Reserve in Chhattisgarh, in the pipeline for 20 years, has become the subject of yet another controversy over the reduction of its size.

    Lemru Elephant Reserve

    • The proposal for the reserve, in Korba district, was passed unanimously by the Assembly in 2005 and got central approval in 2007.
    • Lemru is one of two elephant reserves planned to prevent human-animal conflict in the region, with elephants moving into Chhattisgarh from Odisha and Jharkhand.
    • Its area was then proposed to be 450 sq km.

    Why does the government want to reduce the size of the reserve?

    • The area proposed under the reserve is part of the Hasdeo Aranya forests, a very diverse biozone that is also rich in coal deposits.
    • Of 22 coal blocks in the area, seven have already been allotted with mines running in three, and in the process of being established in the other four.
    • Under the ‘No-Go Area’ policy from the UPA area, the entire area was considered out of bounds for mines, but in 2020, five coal blocks from the region were put on the auction list.

    Why is the reserve important?

    • North Chhattisgarh alone is home to over 240 elephants.
    • Elephants in Chhattisgarh are relatively new; they started moving into undivided Madhya Pradesh in 1990.
    • Since these animals were relatively new, the human-animal conflict started once elephants started straying into inhabited areas, looking for food.

  • Graded Response Action Plan (GRAP)

    Fearing any surge in coronavirus cases in the national capital, which is witnessing a decline in cases of infection, the Delhi government has chalked out the ‘Graded Response Action Plan (GRAP).’

    Graded Response Action Plan (GRAP)

    • In 2014, when a study by the WHO found that Delhi was the most polluted city in the world, panic spread in the Centre and the state government.
    • Approved by the Supreme Court in 2016, the plan was formulated after several meetings that the Environment Pollution (Prevention and Control) Authority (EPCA) held with state government and experts.
    • The result was a plan that institutionalized measures to be taken when air quality deteriorates.
    • GRAP also works as an emergency measure.
    • It includes strict measures such as a ban on the entry of heavy vehicles, the odd-even road rationing restrictions, and a halt of construction work – each of which is likely to be impractical at a time when the pandemic has exacted heavy economic costs and public transport has been seen as an infection risk.

    For covid purposes

    • This time, it was decided to notify the GRAP that will “objectively and transparently” ensure an “institutional and automatic” response with regards to enforcement measures, lockdowns and unlock activities.
    • The plan was prepared in comparison with ascent data of the four waves at specific positivity rates of 0.5%, 1%, 2% and 5% and also considered on the basis of the earlier four waves.

  • [pib] Species in news: Avicennia Marina

    Scientists at the Department of Biotechnology (DBT) have reported for the first time a reference-grade whole genome sequence of a highly salt-tolerant and salt-secreting true-mangrove species Avicennia Marina.

    Avicennia marina

    • Avicennia marina is one of the most prominent mangroves species found in all mangrove formations in India.
    • It is a salt-secreting and extraordinarily salt-tolerant mangrove species that grows optimally in 75% seawater and tolerates >250% seawater.
    • It is among the rare plant species, which can excrete 40% of the salt through the salt glands in the leaves, besides its extraordinary capacity to exclude salt entry to the roots.

    Why in news?

    • The A. marina genome assembled in this study is nearly complete and can be considered as a reference-grade genome reported so far for any mangrove species globally and the first report from India.
    • This study assumes significance as agriculture productivity globally is affected due to abiotic stress factors such as limited water availability and salinization of soil and water.

    Its significance

    • Availability of water is a signiïŹcant challenge to crop production in dryland areas, accounting for ~40 per cent of the world’s total land area.
    • Salinity is prevalent in ~900 million hectares globally (with an estimated 6.73 million ha in India), and it is estimated to cause an annual loss of 27 billion USD.
    • The genomic resources generated in the study will pave the way for researchers to study the potential of the identified genes for developing drought and salinity tolerant varieties of important crop species.
    • This is particularly important for the coastal region as India has 7,500m of coastline and two major island systems.

    Try these PYQs:

    Q.Which one of the following is the correct sequence of ecosystems in the order of decreasing productivity? (CSP 2013)

    (a) Oceans, lakes, grasslands, mangroves

    (b) Mangroves, oceans, grasslands, lakes

    (c) Mangroves, grasslands, lakes, oceans

    (d) Oceans, mangroves, lakes, grasslands

     

    Q.The 2004 Tsunami made people realize that mangroves can serve as a reliable safety hedge against coastal calamities. How do mangroves function as a safety hedge? (CSP 2011)

    (a) The mangrove swamps separate the human settlements from the sea by a wide zone in which people neither live nor venture out

    (b) The mangroves provide both food and medicines which people are in need of after any natural disaster

    (c) The mangrove trees are tall with dense canopies and serve as an excellent shelter during a cyclone or tsunami

    (d) The mangrove trees do not get uprooted by storms and tides because of their extensive roots.

    Back2Basics: Mangroves

    • A mangrove is a shrub or small tree that grows in coastal saline or brackish water.
    • Mangroves occur worldwide in the tropics and subtropics, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator.
    • Mangroves are salt-tolerant trees, also called halophytes, and are adapted to live in harsh coastal conditions.
    • They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action.
    • They are adapted to the low-oxygen conditions of waterlogged mud.
    • They are a unique group of species found in marshy intertidal estuarine regions and survive a high degree of salinity through several adaptive mechanisms.
    • They form a link between marine and terrestrial ecosystems, protect shorelines, provide habitat for a diverse array of terrestrial organisms.

  • Need for coordinated database for tracking fugitives

    Context

    India lacks a domestic tracking system for fugitives. That makes it easier for them to evade the criminal justice system.

    Challenges at investigation and prosecution level

    • Central agencies have developed reasonable expertise in investigation and prosecution because they are focussed only on investigation and prosecution work.
    • On the other hand, State police forces (except specialised wings) are engaged in law-and-order work as well as investigations.
    • The bulk of the investigation and prosecution work happens at police stations in the States.
    • There is a tendency to close investigations once the accused have absconded.
    • Some police stations do initiate proceedings for attachment of property and declaration of the accused as proclaimed offenders, but the number of cases where coordinated efforts are made to pursue fugitives – domestically or internationally – are hardly documented.

    No system for tracking criminals domestically

    • Through Interpol Notices and the sharing of immigration databases of different countries, there exists a system of tracking criminals worldwide.
    • However, there is no coordinated system or database for tracking criminals or wanted persons domestically in India.
    • In the absence of such a system, it is relatively easy for criminals from one police station/jurisdiction to melt into the population in any other area, almost undetected.

    Way forward

    • The creation of a nationwide database of wanted persons, which could be accessible for police agencies, the public and others is needed.
    • A nation-wide system of ‘Wanted Persons Notices’, similar to Interpol Notices, is required, to help track fugitives domestically.
    • The Crime and Criminal Tracking Network and Systems and the National Intelligence Grid are efforts in the right direction/
    • Countries like the U.S. have functional inter-State extradition and fugitive tracking systems.
    • India needs to set up such dedicated ‘fugitive tracking units’.
    • There needs to be enhanced integration between immigration agencies, State police agencies, Interpol-New Delhi, the External Affairs Ministry and Home Ministry and central investigation agencies.
    • Sharing India’s ‘wanted’ database or providing access to it to foreign embassies on a reciprocal basis or through treaties or arrangements would also be helpful.
    • Signing of more bilateral and multilateral conventions on criminal matters would help plug legal infirmities.
    • Signing bilateral agreements on cooperation in policing matters would also help.
    • All relevant legal processes and requirements should be incorporated into one consolidated law on international cooperation.
    • The entire gamut of activities pertaining to fugitives, from investigation to extradition, needs to be incorporated into a specialised set-up.

    Conclusion

    In the absence of a coordinated database, criminals can go undetected. What we need is a watertight system that would deter criminals from hoodwinking the law.

    Back2Basics: Crime and Criminal Tracking Network and Systems (CCTNS)

    • CCTNS aims at creating a comprehensive and integrated system for enhancing the efficiency and effective policing at all levels and especially at the Police Station level.
    • It aism at adoption of principles of e-Governance, and creation of a nationwide networked infrastructure for evolution of IT-enabled state of- the-art tracking system around “investigation of crime and detection of criminals” in real time.
    • It is is a critical requirement in the context of the present day internal security scenario.
    • The scope of CCTNS spans all 35 States and Union Territories and covers all Police Stations (15,000+ in number) and all Higher Police Offices (6,000+ in number) in the country.
    • The CCTNS project includes vertical connectivity of police units (linking police units at various levels within the States – police stations, district police offices, state headquarters, SCRB and other police formations – and States, through state headquarters and SCRB, to NCRB at GOI level) as well as horizontal connectivity, linking police functions at State and Central level to external entities.

    National Intelligence Grid (NATGRID)

    • First conceptualised in 2009, NATGRID seeks to become the one-stop destination for security and intelligence agencies to access database related to immigration entry and exit, banking and telephone details of a suspect on a “secured platform”.
    • All State police are mandated to file First Information Reports (FIR) in the CCTNS.
    • It is only a repository and the data pertaining to FIRs of a particular police station are a State subject.

  • Cabinet extends Agri Infra Fund loans to APMCs

    The Centre has decided to allow state-run market yards to access financing facilities through its Agricultural Infrastructure Fund to calm the fears of protesting farmers that such market yards are being weakened.

    Agriculture Infrastructure Fund (AIF) Schemes

    • It is a Central Sector Scheme meant for setting up storage and processing facilities, which will help farmers, get higher prices for their crops.
    • The Union Cabinet approved this scheme in July 2020 for a period of 10 years.
    • It will support farmers, PACS, FPOs, Agri-entrepreneurs, etc. in building community farming assets and post-harvest agriculture infrastructure.
    • These assets will enable farmers to get greater value for their produce as they will be able to store and sell at higher prices, reduce wastage and increase processing and value addition.

        Note the following things about AIF:

        1) It is a Central Sector Scheme

        2) Duration of the scheme

        3)Target beneficiaries

    What exactly is the AIF?

    • The AIF is a medium – long term debt financing facility for investment in viable projects for post-harvest management infrastructure and community farming assets through interest subvention and credit guarantee.
    • Under the scheme, Rs. 1 Lakh Crore will be provided by banks and financial institutions as loans with an interest subvention of 3% per annum.
    • It will provide credit guarantee coverage under Credit Guarantee Fund Trust for Micro and Small Enterprises (CGTMSE) for loans up to Rs. 2 Crore.

    Target beneficiaries

    The beneficiaries will include farmers:

    • PACS, Marketing Cooperative Societies, FPOs, SHGs, Joint Liability Groups (JLG), Multipurpose Cooperative Societies, Agri-entrepreneurs, Startups, and Central/State agency or Local Body sponsored Public-Private Partnership Projects

    What are the new changes?

    • The Union Cabinet decided to extend the AIF to State agencies and Agricultural Produce Marketing Committees (APMCs), as well as federations of cooperative organizations, Farmers Producers Organizations and self-help groups.
    • They will now be eligible for interest subvention for loans up to â‚č2 crores, with APMCs allowed to access separate loans for different kinds of infrastructure projects to build cold storage, silos, sorting, grading and assaying units in their market yards.
    • The scheme has also been extended to 2032-33.

    Why such a move?

    • The modifications in the Scheme will help to achieve a multiplier effect in generating investments while ensuring that the benefits reach small and marginal farmers.
    • The APMC markets are set up to provide market linkages and create an ecosystem of post-harvest public infrastructure open to all farmers.
    • This is also proof that APMC will not end as the farmers’ concern since the three farm laws.

  • Possibility of life on Saturn’s Moon

    NASA’s Cassini spacecraft has detected an unusually high concentration of methane, along with carbon dioxide and dihydrogen, in the moons of Saturn by flying through their plumes.

    What is the new observation?

    • The spacecraft has found that Titan has methane in its atmosphere and Enceladus has a liquid ocean with erupting plumes of gas and water.

    Are there methane-producing organisms on Earth?

    • Most of the methane on Earth has a biological origin.
    • Microorganisms called methanogens are capable of generating methane as a metabolic byproduct.
    • They do not require oxygen to live and are widely distributed in nature.
    • They are found in swamps, dead organic matter, and even in the human gut.
    • They are known to survive in high temperatures and simulation studies have shown that they can live in Martian conditions.
    • Methanogens have been widely studied to understand if they can be a contributor to global warming.

    Could there be methanogens on Enceladus?

    • We cannot conclude that life exists in the Enceladus ocean.
    • It is the probability that Enceladus’ hydrothermal vents could be habitable to Earth-like microorganisms.
    • There can be life hypotheses.

    What other processes could have produced the methane?

    • Methane could be formed by the chemical breakdown of organic matter present in Enceladus’ core.
    • Hydrothermal processes could help the formation of carbon dioxide and methane.
    • On Earth, hydrothermal vents on seafloors are known to release methane, but this happens at a very slow rate.
    • This hypothesis is plausible but only if Enceladus was formed through the accretion of organic-rich material from comets.
    • The results suggest that methane production from hydrothermal vents is not sufficient to explain the high methane concentration detected by Cassini in the plumes.
    • An additional amount of methane produced via biological methanogenesis could match Cassini’s observations.

  • Centre must step up cash flow to states

    Context

    The states are borrowing less than expected in the first quarter of FY 2021-22 despite the negative impact of state-level restrictions, amidst the second Covid wave, on economic activity.

    An overview of borrowing by States

    • In 2020-21, the gross amount raised through state development loans (SDLs) or bonds had jumped to Rs 8 trillion, up from Rs 6.3 trillion in the previous year.
    • The increase was a fallout of the Covid-19 pandemic on state finances.
    • In the first quarter of the current financial year i.e. 2021-22, gross issuances of bonds stood at Rs 1.4 trillion.
    • This amount is 14 per cent lower than the bonds issued last year (Rs 1.7 trillion).
    • This is also around 20 per cent lower than what states had initially indicated they would borrow (Rs 1.8 trillion) through the indicative calendar of market borrowings released by the RBI.
    • As a result, state bond issuances have undershot expectations in the first quarter.

    Factor’s responsible for lower state borrowing

    •  Lower state borrowings were a consequence of three major factors.
    • First, an additional tax devolution of Rs 450 billion from the Centre in late March.
    • This amount was in excess of the Rs 5.5 trillion tax devolution that had been included in the revised estimates for 2020-21.
    • Second, record-high GST collections in April which doubled to Rs 1.3 trillion in the first quarter of this year, up from Rs 0.6 trillion in the same period last year.
    • Third, receipt of substantial grants from the Centre adding up to Rs 436 billion in April-May related to the recommendations of the Fifteenth Finance Commission.

    Factors that could influence the borrowing pattern in the next three quarters

    • First, the varying pace of unlocking and the consequent economic revival in states from June onwards may crucially affect state borrowings in the second quarter.
    • A faster ramp-up of vaccine administration may help some states, reducing the need to borrow.
    • Second, the eventual calendar for raising back-to-back loans by the GoI to compensate states for the loss in their GST revenues could also result in a change in the states’ borrowing schedule.
    • Third, the quantum, and timing of tax devolution will also play a role.

    Why timing of the Central tax devolution matters for States

    • Central tax devolution forms a quarter of states’ combined revenue receipts.
    • This revenue stream has contracted by 15 per cent in the first two months of the year, falling to Rs 392 billion each in April-May this year, from Rs 460 billion last year.
    • If the Centre continues to devolve to states this amount till February 2022, then a massive Rs 2.4 trillion (36 per cent of the budgeted amount) will be left for devolution in March 2022 — assuming that the devolution for the full year is not revised below the budgeted level.
    • From the states’ point of view, this would be rather inefficient from a cash flow perspective.

    Conclusion

    An early step-up in tax devolution by the central government may provide comfort to the states to accelerate expenditure during another uncertain year, without borrowings being pushed up in the next two quarters.

  • Anti-methanogenic feed supplement ‘Harit Dhara’

    An Indian Council of Agricultural Research (ICAR) institute has developed an anti-methanogenic feed supplement ‘Harit Dhara’.

    Harit Dhara

    • Harit Dhara is prepared using condensed and hydrolysable tannin-rich plant-based sources abundantly available in the country.
    • It changes the composition of the volatile fatty acids that are the end-products of rumen fermentation (along with hydrogen and CO2).
    • It roughly costs Rs 6/kg and it is to be fed only to animals aged above three months having fully functional rumen.
    • When given to bovines and sheep, it not only cuts down their methane emissions by 17-20%.
    • It also results in higher milk production and body weight gain.

    Why it is significant?

    • Belching cattle, buffaloes, sheep and goats in India emit an estimated 9.25 million tonnes (mt) to 14.2 mt of methane annually, out of a global total of 90 mt-plus from livestock.
    • And given methane’s global warming potential – 25 times of carbon dioxide (CO2) over 100 years, making it a more potent greenhouse gas – that’s cause for concern.
    • An average lactating cow or buffalo in India emits around 200 litres of methane per day, while it is 85-95 litres for young growing heifers and 20-25 litres for adult sheep.
    • Feeding Harit Dhara can reduce these by a fifth.

    How is methane produced by the cattles?

    • Methane is produced by animals having rumen, the first of their four stomachs where the plant material they eat – cellulose, fibre, starch and sugars – gets fermented or broken down by microorganisms prior to further digestion and nutrient absorption.
    • Carbohydrate fermentation leads to the production of CO2 and hydrogen.
    • These are used as substrate by archaea – microbes in the rumen with structure similar to bacteria – to produce methane, which the animals then expel through burping.
    • Harit Dhara acts by decreasing the population of protozoa microbes in the rumen, responsible for hydrogen production and making it available to the archaea for reduction of CO2 to methane.
    • Tropical plants containing tannins – bitter and astringent chemical compounds – are known to suppress or remove protozoa from the rumen.

    Need for India

    • The 2019 Livestock Census showed India’s cattle population at 193.46 million, along with 109.85 million buffaloes, 148.88 million goats and 74.26 million sheep.
    • Being largely fed on agricultural residues – wheat/paddy straw and maize, sorghum or bajra stover – ruminants in India tend to produce 50-100% higher methane than their industrialized country counterparts.

    Q.Consider the following:

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

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

    (a) 1 and 2 only

    (b) 2, 3 and 4 only

    (c) 1 and 4 only

    (d) 1, 2, 3 and 4

    Back2Basics: CO2 equivalents

    • Each greenhouse gas (GHG) has a different global warming potential (GWP) and persists for a different length of time in the atmosphere.
    • The three main greenhouse gases (along with water vapour) and their 100-year global warming potential (GWP) compared to carbon dioxide are:

    1 x – carbon dioxide (CO2)

    25 x – methane (CH4) – I.e. Releasing 1 kg of CH4into the atmosphere is about equivalent to releasing 25 kg of CO2

    298 x – nitrous oxide (N2O)

    • Water vapour is not considered to be a cause of man-made global warming because it does not persist in the atmosphere for more than a few days.
    • There are other greenhouse gases which have far greater global warming potential (GWP) but are much less prevalent. These are sulphur hexafluoride (SF6), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs).
    • There are a wide variety of uses for SF6, HFCs, and PFCs but they have been most commonly used as refrigerants and for fire suppression.
    • Many of these compounds also have a depleting effect on ozone in the upper atmosphere.

  • Discrete Auroras on Mars

    The UAE’s Hope spacecraft, which is orbiting Mars since February this year, has captured images of glowing atmospheric lights in the Red Planet’s night sky, known as discrete auroras.

    What causes an Aurora on Earth?

    • Auroras are caused when charged particles ejected from the Sun’s surface — called the solar wind — enter the Earth’s atmosphere.
    • These particles are harmful, and our planet is protected by the geomagnetic field, which preserves life by shielding us from the solar wind.
    • However, at the north and south poles, some of these solar wind particles are able to continuously stream down, and interact with different gases in the atmosphere to cause a display of light in the night sky.
    • This display, known as an aurora, is seen from the Earth’s high latitude regions (called the auroral oval), and is active all year round.

    Where are they observed on Earth?

    • In the northern part of our globe, the polar lights are called aurora borealis or Northern Lights and are seen from the US (Alaska), Canada, Iceland, Greenland, Norway, Sweden and Finland.
    • In the south, they are called aurora australis or southern lights and are visible from high latitudes in Antarctica, Chile, Argentina, New Zealand and Australia.

    So, how are Martian auroras different?

    • Unlike auroras on Earth, which are seen only near the north and south poles, discrete auroras on Mars are seen all around the planet at night time.
    • Unlike Earth, which has a strong magnetic field, the Martian magnetic field has largely died out.
    • This is because the molten iron at the interior of the planet– which produces magnetism– has cooled.
    • However, the Martian crust, which hardened billions of years ago when the magnetic field still existed, retains some magnetism.
    • So, in contrast with Earth, which acts like one single bar magnet, magnetism on Mars is unevenly distributed, with fields strewn across the planet and differing in direction and strength.
    • These disjointed fields channel the solar wind to different parts of the Martian atmosphere, creating “discrete” auroras over the entire surface of the planet as charged particles interact with atoms and molecules in the sky– as they do on Earth.

    Why is it important to study them?

    • Studying Martian auroras is important for scientists, for it can offer clues as to why the Red Planet lost its magnetic field and thick atmosphere– among the essential requirements for sustaining life.

    Q.Which region of Mars has a densely packed river deposit indicating this planet had water 3.5 billion years ago?

    (a) Aeolis Dorsa

    (b) Tharsis

    (c) Olympus Mons

    (d) Hellas

    Back2Basics:

    Hope Orbiter

    • The Hope Probe, the Arab world’s first mission to Mars, took off from Earth in July last year, and has been orbiting the Red Planet since February.
    • The primary objective of the mission is to study Martian weather dynamics.
    • By correlating the lower atmosphere and upper atmosphere conditions, the probe will look into how weather changes the escape of hydrogen and oxygen into space.
    • By measuring how much hydrogen and oxygen is spilling into space, scientists will be able to look into why Mars lost so much of its early atmosphere and liquid water.
    • It is expected to create the first complete portrait of the planet’s atmosphere.
    • With the information gathered during the mission, scientists will have a better understanding of the climate dynamics of different layers of Mars’ atmosphere.

    Mars

    • Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury.
    • In English, Mars carries the name of the Roman god of war and is often referred to as the “Red Planet”.
    • The latter refers to the effect of the iron oxide prevalent on Mars’s surface, which gives it a reddish appearance distinctive among the astronomical bodies visible to the naked eye.
    • Mars is a terrestrial planet with a thin atmosphere, with surface features reminiscent of the impact craters of the Moon and the valleys, deserts and polar ice caps of Earth.
    • The days and seasons are comparable to those of Earth, because the rotational period, as well as the tilt of the rotational axis relative to the ecliptic plane, is similar.
    • Mars is the site of Olympus Mons, the largest volcano and highest known mountain on any planet in the Solar System, and of Valles Marineris, one of the largest canyons in the Solar System.

  • New online platform maps Pegasus spread

    An online database about the use of the spyware Pegasus was recently launched by the Forensic Architecture, Amnesty International and the Citizen Lab to document attacks against human rights defenders.

    What is Pegasus?

    • Last year, one of the biggest stories that broke into cyberspace was WhatsApp’s reports that 1,400 of its users were hacked by Pegasus, a spyware tool from Israeli firm NSO Group.
    • All spyware do what the name suggests — they spy on people through their phones.
    • Pegasus works by sending an exploit link, and if the target user clicks on the link, the malware or the code that allows the surveillance is installed on the user’s phone.
    • A presumably newer version of the malware does not even require a target user to click a link.
    • Once Pegasus is installed, the attacker has complete access to the target user’s phone.

    Why is Pegasus dangerous?

    • What makes Pegasus really dangerous is that it spares no aspect of a person’s identity. It makes older techniques of spying seem relatively harmless.
    • It can intercept every call and SMS, read every email and monitor each messaging app.
    • Pegasus can also control the phone’s camera and microphone and has access to the device’s location data.
    • The app advertises that it can carry out “file retrieval”, which means it could access any document that a target might have stored on their phone.
