    Q.What is “Terminal High Altitude Area Defense (THAAD)”, sometimes seen in the news?

    (a) An Israeli radar system

    (b) India’s indigenous anti-missile programme

    (c) An American anti-missile system

    (d) A defence collaboration between Japan and South Korea

    MQ-9B Sea Guardian

    • The Guardian, which is the maritime variant of the Predator MQ-9 UAV, has a maximum endurance of 40 hours and a maximum flying altitude of 40,000 feet.
    • It has 360-degree maritime surveillance radar and optional multimode maritime surface search radar.
    • The drone can perform over-the-horizon long-endurance, medium-altitude Intelligence, Surveillance and Reconnaissance (ISR) missions.
    • The recently released Defence Acquisition Procedure (DAP) 2020 has introduced an option for leasing military platforms.
    • The Basic Exchange and Cooperation Agreement for Geo-Spatial Cooperation (BECA) has simplified such high- technology cooperation.

    About BECA

    • BECA will help India get real-time access to American geospatial intelligence that will enhance the accuracy of automated systems and weapons like missiles and armed drones.
    • Through the sharing of information on maps and satellite images, it will help India access topographical and aeronautical data, and advanced products that will aid in navigation and targeting.
    • This could be a key to Air Force-to-Air Force cooperation between India and the US.
    • BECA will provide Indian military systems with a high-quality GPS to navigate missiles with real-time intelligence to precisely target the adversary.
    • Besides the sailing of ships, flying off aircraft, fighting of wars, and location of targets, geospatial intelligence is also critical to the response to natural disasters.

  • Desalination Plants and their Feasibility

    Maharashtra state govt. has announced the setting up of a desalination plant in Mumbai, becoming the fourth state in the country to experiment with the idea.

    Try this PYQ:

    Q.What is the role of ultraviolet (UV) radiation in the water purification systems?

    1. It inactivates/kills the harmful microorganisms in water.
    2. It removes the entire undesirable odour from the water.
    3. It quickens the sedimentation of solid particles, removes turbidity and improves the clarity of water.

    Which of the statements given above is/are correct?

    (a) 1 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

    What are Desalination Plants?

    • A desalination plant turns salt water into water that is fit to drink.
    • The most commonly used techniques used for the process is reverse osmosis where external pressure is applied to push solvents from an area of high-solute concentration to an area of low-solute concentration through a membrane.
    • The microscopic pores in the membranes allow water molecules through but leave salt and most other impurities behind, releasing clean water from the other side.
    • These plants are mostly set up in areas that have access to seawater.

    How widely is this technology used in India?

    • Desalination has largely been limited to affluent countries in the Middle East and has recently started making inroads in parts of the United States and Australia.
    • In India, Tamil Nadu has been the pioneer in using this technology, setting up two desalination plants near Chennai in 2010 and then 2013, while there are two more to come.

    Need for such plant

    • According to the projections, the population of Mumbai is anticipated to touch 1.72 crores by 2041 and accordingly, the projected water demand would be 6424 MLD by then.
    • Currently, BMC supplies 3850 MLD as against the requirement of 4200 MLD each day.

    Is it ecologically safe?

    • The high cost of setting up and running a desalination plant is one reason why the Maharashtra government has over the last decade been hesitant in building such a plant.
    • Desalination is an expensive way of generating drinking water as it requires a high amount of energy.
    • The other problem is the disposal of the byproduct — highly concentrated brine (saltwater) — of the desalination process.
    • While in most places brine is pumped back into the sea, there have been rising complaints that it ends up severely damaging the local ecology around the plant.

    Back2Basics: Osmosis and Reverse Osmosis

    • Osmosis is a phenomenon where pure water flows from a dilute solution through a semi-permeable membrane to a higher concentrated solution.
    • Semi-permeable means that the membrane will allow small molecules and ions to pass through it but acts as a barrier to larger molecules or dissolved substances.
    • As water passes through the membrane to the salt solution, the level of liquid in the saltwater compartment will rise until enough pressure, caused by the difference in levels between the two compartments, is generated to stop the osmosis.
    • This pressure, equivalent to a force that the osmosis seems to exert in trying to equalize concentrations on both sides of the membrane, is called osmotic pressure.
    • If pressure greater than the osmotic pressure is applied to the high concentration the direction of water flow through the membrane can be reversed.
    • This is called reverse osmosis. Note that this reversed flow produces pure water from the salt solution since the membrane is not permeable to salt.

  • What are Negative-Yield Bonds?

    China recently sold negative-yield debt for the first time, and this saw high demand from investors across Europe.

    Try this PYQ:

    Q.Which of the following is issued by registered foreign portfolio investors to overseas investors who want to be part of the Indian stock market without registering themselves directly?

    (a) Certificate of Deposit

    (b) Commercial Paper

    (c) Promissory Note

    (d) Participatory Note

    What are Negative-Yield Bonds?

    • These are debt instruments that offer to pay the investor a maturity amount lower than the purchase price of the bond.
    • These are generally issued by central banks or governments, and investors pay interest to the borrower to keep their money with them.

    Why do investors buy them?

    • Negative-yield bonds attract investments during times of stress and uncertainty as investors look to protect their capital from significant erosion.
    • At a time when the world is battling the Covid-19 pandemic and interest rates in developed markets across Europe are much lower.
    • Hence, investors are looking for relatively better-yielding debt instruments to safeguard their interests.

    Why is there a huge demand?

    • While Europe, the US and other parts of the world are facing a second wave of Covid-19 cases, China has demonstrated that it has controlled the spread of the pandemic and is therefore seen as a more stable region.
    • Many feel that European investors are also looking to increase their exposure in China, and hence there is a huge demand for these bonds.
    • The fact that the 10-year and 15-year bonds are offering positive returns is a big attraction at a time when interest rates in Europe have dropped significantly.
    • As against minus —0.15% yield on the 5-year bond issued by China, the yields offered in safe European bonds are much lower, between –0.5% and —0.75%.

  • [pib] Who was Lachit Borphukan?

    The Prime Minister has paid tribute to Lachit Borphukan on Lachit Diwas.

    (d) He wanted to annex all the fertile plains of Punjab upto borders of Delhi to his kingdom

    Who was Lachit Borphukan?

    • The year was 1671 and the decisive Battle of Saraighat was fought on the raging waters of the Brahmaputra.
    • On one side was Mughal Emperor Aurangzeb’s army headed by Ram Singh of Amer (Jaipur) and on the other was the Ahom General Lachit Borphukan.
    • He was a commander in the Ahom kingdom, located in present-day Assam.
    • Ram Singh failed to make any advance against the Assamese army during the first phase of the war.
    • Lachit Borphukan emerged victorious in the war and the Mughals were forced to retreat from Guwahati.

    Lachit Diwas

    • On 24 November each year, Lachit Divas is celebrated statewide in Assam to commemorate the heroism of Lachit Borphukan.
    • On this day, Borphukan has defeated the Mughal army on the banks of the Brahmaputra in the Battle of Saraighat in 1671.
    • The best passing out cadet of National Defence Academy has conferred the Lachit gold medal every year since 1999 commemorating his valour.

    • One hundred and fifteen of his hymns are in Guru Granth Sahib.
    • He stood up for the rights of Kashmiri Pandits who approached him against the imposition jizya tax.
    • He was publicly killed in 1675 on the orders of Mughal emperor Aurangzeb in Delhi for refusing to convert.
    • In the words of Noel King of the University of California, “Guru Teg Bahadur’s martyrdom was the first-ever martyrdom for human rights in the world.
    • He is fondly remembered as ‘Hind di Chaadar’.

  • India’s Deep Ocean Mission

    India will soon launch an ambitious ‘Deep Ocean Mission’ that envisages exploration of minerals, energy and marine diversity of the underwater world, a vast part of which still remains unexplored.

    Deep Ocean Mission (DOM)

    Nodal Agency: Ministry of Earth Sciences (MoES)

    • The mission proposes to explore the deep ocean similar to the space exploration started by ISRO.
    • Underwater robotics and ‘manned’ submersibles are key components of the Mission which will help India harness various living and non-living (water, mineral and energy) resources from the seabed and deep water.
    • The tasks that will be undertaken over this period include deep-sea mining, survey, energy exploration and the offshore-based desalination.
    • These technological developments are funded under an umbrella scheme of the government – called Ocean Services, Technology, Observations, Resources Modelling and Science (O-SMART).

     Mining PMN

    • One of the main aims of the mission is to explore and extract polymetallic nodules (PMN).
    • These are small potato-like rounded accretions composed of minerals such as manganese, nickel, cobalt, copper and iron hydroxide.
    • They lie scattered on the Indian Ocean floor at depths of about 6,000 m and the size can vary from a few millimetres to centimetres.
    • These metals can be extracted and used in electronic devices, smartphones, batteries and even for solar panels.

    Where will the team mine?

    • The International Seabed Authority (ISA), an autonomous international organisation established under the 1982 United Nations Convention on the Law of the Sea, allots the ‘area’ for deep-sea mining.
    • India was the first country to receive the status of a ‘Pioneer Investor ‘ in 1987 and was given an area of about 1.5 lakh sq km in the Central Indian Ocean Basin (CIOB) for nodule exploration.
    • In 2002, India signed a contract with the ISA and after complete resource analysis of the seabed 50% was surrendered and the country retained an area of 75,000 sq km.

    Which are the other countries that are in the race to mine the deep sea?

    • Apart from the CIOB, polymetallic nodules have been identified from the central Pacific Ocean. It is known as the Clarion-Clipperton Zone.
    • According to the ISA’s website, it has entered into 15-year contracts for exploration for polymetallic nodules, polymetallic sulphides and cobalt-rich ferromanganese crusts in the deep seabed with 29 contractors.
    • Later it was extended for five more years till 2022.
    • China, France, Germany, Japan, South Korea, Russia and also some small islands such as the Cook Islands, Kiribati have joined the race for deep-sea mining.
    • Most of the countries have tested their technologies in shallow waters and are yet to start deep-sea extraction.

    India’s preparedness

    • India’s mining site is at about a depth of 5,500 metres, where there is a high pressure and extremely low temperature.
    • We have also deployed Remotely Operated Vehicle and In-situ Soil Tester in the depth of 6,000 metres and have a thorough understanding of the mining area at the Central Indian Ocean Basin.
    • The mining machine newly developed for 6000 metres depth was able to move about 900 metres and will be deployed soon at 5,500 metres.
    • Weather conditions and the availability of ships also play a role.
    • More tests are being conducted to understand how to bring the nodules up to the surface. A riser system comprising an umbilical cable or electromechanical cable and a hose is being developed.

    What will be the environmental impact?

    • According to the IUCN, these deep remote locations can be home to unique species that have adapted themselves to conditions such as poor oxygen and sunlight, high pressure and extremely low temperatures.
    • Such mining expeditions can make them go extinct even before they are known to science.
    • The deep sea’s biodiversity and ecology remain poorly understood, making it difficult to assess the environmental impact and frame adequate guidelines.
    • Though strict guidelines have been framed, they are only exploration guidelines. A new set of exploitation guidelines are being worked out and discussions are on with the ISA.
    • Environmentalists are also worried about the sediment plumes that will be generated as the suspended particles can rise to the surface harming the filter feeders in the upper ocean layers.
    • Additional concerns have been raised about the noise and light pollution from the mining vehicles and oil spills from the operating vessels.

    Is deep-sea mining economically viable?

    • The latest estimate from the ISA says it will be commercially viable only if about three million tonnes are mined per year.
    • More studies are being carried out to understand how the technology can be scaled up and used efficiently.

  • Species in news: Meghalaya’s Glowing Mushrooms

    A mushroom documentation project in the forests of Northeast India has discovered a bioluminescent — or light-emitting — variety of mushroom.

    Try this PYQ:

    Q.Lichens, which are capable of initiating ecological succession even on a bare rock, are actually a symbiotic association of:

    (a) Algae and bacteria

    (b) Algae and fungi

    (c) Bacteria and fungi

    (d) Fungi and mosses

    Roridomyces phyllostachydis

    • The new species was first sighted near a stream in Meghalaya’s Mawlynnong in East Khasi Hills district and later at Krang Shuri in West Jaintia Hills district.
    • It is now one among the 97 known species of bioluminescent fungi in the world.

    Bioluminescence in fungi

    • Bioluminescence is the property of a living organism to produce and emit light.
    • Bioluminescent organisms are usually found in ocean environments, but they are also found in terrestrial environments.
    • The colour of the light emitted by the organism depends on its chemical properties.
    • In the case of fungi, the luminescence comes from the enzyme, luciferase.
    • The green light emits when luciferans is catalysed by the enzyme luciferase, in the presence of oxygen.

  • Exercise SITMEX-20

    The second edition of the India, Thailand and Singapore trilateral naval exercise SITMEX-20 has concluded in the Andaman Sea.

    Exercise SITMEX-20

    • The SITMEX series of exercises are conducted to enhance mutual inter-operability and imbibing best practices between IN, Republic of Singapore Navy (RSN) and Royal Thai Navy (RTN).
    • The first edition of SITMEX, hosted by Indian Navy, was conducted off Port Blair in September 2019.
    • The 2020 edition of the exercise is being hosted by RSN.
    • The maritime drill witnessed a variety of exercises including naval manoeuvres, surface warfare exercises and weapon firings.
    • Besides improving inter-operability, SITMEX series of exercise also aims to strengthen mutual confidence and develop common understanding and procedures towards enhancing the overall maritime security in the region.

  • Sustaining India’s Growth Momentum

    The article highlights the factors that explain that India’s economic recovery is broad-based and sustainable in nature.

    Revising India’s GDP forecast

    • With major banks, investor advisory groups, and credit rating agencies revising their GDP forecasts for the next financial year while lowering estimates of economic contraction for this fiscal, surely the bounce back is well on track.
    • Some of the earlier assessments were too pessimistic and assumed a gradual pace of economic normalisation.
    • Thus, a reassessment was given but nevertheless welcome.

    Many continue to challenge conventional belief regarding India’s economic recovery being broad-based and sustainable in nature. It is important that we look at underlying data and relate it with steps undertaken by the government with the sole objective of reviving India’s economy.

    1) Employment figures

    •  Economic activity will see a faster revival than employment figures as labour markets tend to lag.
    • This is because most firms face costs associated with hiring and firing and they prefer to adjust the working hours before adjusting employment numbers.
    • Trends labour market does indicate prospects of a cyclical recovery which will lead to jobs being added at a faster pace than what was originally estimated.
    • Critically, the new scheme subsiding part of the EPFO contribution for the unskilled workers will benefit enormously which will then have spill-over effects.

    2) Normalisation driven by rural economy

    • The bulk of the normalisation of economic activity was driven by the rural economy which eventually benefited the rest of the economy.
    • Rural growth has gained momentum and definitely augurs well for the Indian economy as it gets one of the engines firing.
    • The strong push by the government towards financing construction of assets has a significant impact.

    3) Avoiding excessive and inefficient use of public funds

    • The design of the aid by the government is similar in terms of its size to programmes announced by other emerging markets.
    • However, the choice of instruments is along the lines those deployed by developed countries.
    • The government has refrained from excessive and inefficient use of public funds by restricting expenditures to temporary fiscal commitments.
    • This is important as our 2008 response had a lot of permanent fiscal expenditures which led to a systematic deterioration of our macroeconomic fundamentals.
    • The government has taken undertaken a sizable fiscal expansion combining automatic stabilizers, cash transfers, bank guarantees, expansion of expenditure under various programs such as MGNREGA, Food Security Act and Urban Affordable Housing Measures.
    • The fiscal component under each of these policies can be easily reversed making it possible for India to revert to its fiscal consolidation path a lot sooner.

    4) Structural reforms as a part of its economic response package

    • These reforms are geared at unshackling the productivity potential in areas such as APMCs,  labour markets, other reforms that allow for greater private role within the economy in critical areas such as coal, space technology etc.
    • These moves and their productivity gains will help India improve its potential growth rate.
    • This means that India should be better equipped at sustaining a high-growth rate of above 7 per cent due to the productivity gains that will be an outcome of the proposed reforms.
    • This will further help a faster reduction in fiscal deficit as a percentage of GDP and our public debt to GDP figures.

    Conclusion

    Strong macroeconomic fundamentals are necessary for sustained economic growth and the government has focused on a response package which prioritises sustainability of growth rather than having a fast yet unsustainable economic recovery from the crisis.

  • Analysing India’s economic growth

    The article analyses India’s economic trajectory after independence and divides it into five phases. India’s progress is also compared with Pakistan’s as both countries have had much in common.

    What drives economic growth

    • Examining the experiences of different countries to analysing the growth may seem a promising approach.
    • However, generalising from specific experiences can be misleading since ground conditions vary hugely across countries.
    • There are two ways to avoid the pitfalls of generalising from specific cases.
    • 1) The first is to examine the same country over time to look for changes in outcomes at specific points in time.
    • 2) A second approach is to compare countries with shared history, culture and geography.
    • If there are stark differences in outcomes between them, then there may be some policy lessons to be drawn.

    The Indian subcontinent provides lessons from both approaches. The 73 years of post-Independence India has generated a lot of evidence across different political-economic regimes. This period has also provided us with the contrasting experiences of India and Pakistan, two countries that share history, geography and socio-cultural mores.

    5 phases of India’s economic progress in 73 years: first approach

    • 1) The first phase was the period 1950-65. This was the Nehruvian period of state-led industrialisation.
    • Starting in 1950 annual per person GDP growth averaged 2 per cent during this period.
    • This translated to aggregate annual GDP growth of around 4 per cent since the population was growing at close to 2 per cent.
    • 2) The second phase of post-Independence India was during 1965-84.
    • This period was an unmitigated economic disaster with negative per capita growth.
    • The phase was marked with increasing state control of the economy, nationalisation of industry, closing of the economy to trade and a systematic weakening of institutions.
    • 3) The third phase is 1984-91 when the government ushered in the first round of economic reforms by liberalising capital goods imports as well as starting industrial de-licensing.
    • These reforms were rewarded by a growth take-off. India’s annual per capita GDP growth averaged 3.1 per cent while aggregate GDP grew at 5.2 per cent during 1984-91.
    • 4) The period 1991-2004 is typically classified as the liberalisation phase.
    • The reform effort was reflected in the 4.9 per cent annual per capita GDP growth during 1991-2004.
    • 5) India embarked on a distinctive phase of faster growth post-2004 on the back of large investments in infrastructure.
    • Per person GDP growth in the period 2004-2015 averaged 7.7 per cent.
    • The corresponding aggregate GDP growth averaged 9 per cent.
    • This came at a cost, as a number of these infrastructure projects later caused problems in the banking sector on account of burgeoning NPAs, a problem that continues till today.

    Comparison with Pakistan

    • In 1950, Pakistan’s per person GDP was almost 50 per cent greater than India that year.
    • Due to political uncertainty, Pakistan stagnated throughout the 1950s while a politically stable India grew.
    • As a result, by 1960, India had almost caught up with Pakistan in per capita GDP terms.
    • Unfortunately, from 1964, India went into two decades of economic stagnation while Pakistan opened up to foreign capital.
    • By 1984, Pakistan’s per capita income was more than double that of India’s.
    • Pakistan’s slowdown began in the 1980s.
    • This period coincided with the reforms in India.
    • Nevertheless, it wasn’t till as recently as 2010 that India’s per capita GDP finally overtook Pakistan.

    4 takeaways

    •  First, openness to trade and private enterprise usually has positive effects on growth.
    • Second, rapacious and exploitative democratic systems do not necessarily promote growth. Pakistan in the 1950s, 1990 and post-2010 is a good example.
    • Third, the socio-economic environment surrounding religious fundamentalism may be inimical to growth.
    • Fourth, degradation of institutions that regulate, arbitrate and enforce laws can be costly.

    Conclusion

    India’s growth when analysed from both the perspective offers valuable lessons for India and these lessons must guide India’s future economic trajectory.
