GS Paper: GS3

  • Israel’s Iron Dome rocket defence system

    Context

    • Amid the Israel-Palestine conflict, the night sky over Israel has been ablaze with interceptor missiles from Iron Dome shooting down the incoming rockets in the sky.

    What is Iron Dome?

    • Iron Dome is a multi-mission system capable of intercepting rockets, artillery, mortars and Precision Guided Munitions as well as aircraft, helicopters and Unmanned Aerial Vehicles (UAV) over short ranges of up to 70 km.
    • It is an all-weather system and can engage multiple targets simultaneously and can be deployed over land and sea.
    • Iron Dome is jointly manufactured by Rafael Advanced Systems and has been in service with Israeli Air Force since 2011.
    • The radar system was developed by Elta.

    Working of Iron Dome

    • An Iron Dome battery consists of a battle management control unit, a detection and tracking radar and a firing unit of three vertical launchers, with 20 interceptor missiles each.
    • The interceptor missile uses a proximity fuse to detonate the target warhead in the air.
    • One of the system’s important advantages is its ability to identify the anticipated point of impact of the threatening rocket, to calculate whether it will fall in a built-up area or not, and to decide on this basis whether or not to engage it.
    • This prevents unnecessary interception of rockets that will fall in open areas and thus not cause damage, the paper states.
    • The system has intercepted thousands of rockets so far and, according to Rafael Advanced Systems, its success rate is over 90%.

    Limitations of the system

    • The system can see limitations when it is overwhelmed with a barrage of projectiles.
    • The system has a ‘saturation point’.
    • It is capable of engaging a certain number of targets at the same time, and no more.
    • One of the possible limitations is the system’s inability to cope with very short range threats as estimates put the Iron Dome’s minimum interception range at 5-7 kilometres.

     

  • Remittance received by India remain unaffected by pandemic

    What the World Bank report says

    • India received over USD 83 billion in remittances in 2020, according to a World Bank report.
    • In 2019, India had received USD 83.3 billion in remittances.
    • The report said India’s remittances fell by just 0.2 per cent in 2020.
    • Much of the decline was due to a 17 per cent drop in remittances from the United Arab Emirates, which offset resilient flows from the United States and other host countries.
    • The World Bank, in its latest Migration and Development Brief, said despite COVID-19, remittance flows remained resilient in 2020.

    Trend analysis

    • China, which received USD 59.5 billion in remittances in 2020 against USD 68.3 billion the previous year, is a distant second.
    • India and China are followed by Mexico (USD42.8 billion), the Philippines (USD34.9 billion), Egypt (USD29.6 billion), Pakistan (USD26 billion), France (USD24.4 billion) and Bangladesh (USD21 billion).
    • Remittance outflow was the maximum from the United States (USD68 billion), followed by UAE (USD43 billion), Saudi Arabia (USD34.5 billion), Switzerland (USD27.9 billion), Germany (USD22 billion), and China (USD18 billion).
    • The relatively strong performance of remittance flows during the COVID-19 crisis has also highlighted the importance of timely availability of data.
    • Given its growing significance as a source of external financing for low- and middle-income countries, there is a need for better collection of data on remittances, in terms of frequency, timely reporting, and granularity by corridor and channel.

    B2BASICS

    Remittances

    • Remittances are usually understood as financial or in-kind transfers made by migrants to friends and relatives back in communities of origin.
    • These are basically sum of two main components – Personal Transfers in cash or in kind between resident and non-resident households and Compensation of Employees, which refers to the income of workers who work in another country for a limited period of time.
    • Remittances help in stimulating economic development in recipient countries, but this can also make such countries over-reliant on them.

    Remittance and the Indian Economy

    Benefits

    • Increased inward remittance is a boon for the economy at both macro and micro levels.
    • At the macro level, remittances contribute to maintaining stable foreign reserves.
    • Remittances help Indian Rupee hold its value against the US dollar and forms a significant part of the GDP.
    • On a micro level, remittances have shown a positive impact on healthcare, entrepreneurship, education, and overall economic development of the recipient families.

    Issues

    An increase in outward remittances however, raises an alarm. It causes the rupee to weaken against the dollar, which in return impacts the businesses exposed to foreign exchange, and the economy overall.

  • Risk of mucormycosis in Covid-19 patients

    About mucormycosis

    • Mucormycosis is a fungal infection that has a high mortality rate of 50 per cent.
    • An increasing number of Covid-19 patients have been developing this infection while still at the hospital or after discharge.
    • The disease often manifests in the skin and also affects the lungs and the brain.
    • Some of the common symptoms include sinusitis, blackish nasal discharge, facial pain, headaches, and pain around the eyes.

    Who is at risk

    • Patients who have been hospitalised for Covid-19 and particularly those who require oxygen therapy during Covid-19 illness are at a much higher risk of mucormycosis.
    • However, there are some cases of mucormycosis in patients with asymptomatic Covid-19 infection.
    • Before the pandemic, patients with uncontrolled diabetes were at a higher risk of mucormycosis.
    • The risk of mucormycosis rises for these patients for two reasons.
    • First is that Covid-19 further impairs their immune system.
    • Second, they are given corticosteroids for their treatment it leads to a rise in their blood sugar level thus increasing their risk of mucormycosis.

    Treatment

    • Today, we have a number of drugs and anti-fungal medicines that can treat mucormycosis.
    • These are given by IV or taken orally.
    • Surgery is needed to remove the affected dead tissues along with antifungal therapy.

  • National Programme on Advanced Chemistry Cell Battery Storage

    About the scheme

    • The Cabinet, chaired by Prime Minister has approved the proposal of Department of Heavy Industry for implementation of the Production Linked Incentive (PLI) Scheme ‘National Programme on Advanced Chemistry Cell (ACC) Battery Storage’.
    • Each selected ACC battery Storage manufacturer would have to commit to set-up an ACC manufacturing facility of minimum five (5) GWh capacity and ensure a minimum 60% domestic value addition at the Project level within five years.
    • Furthermore, the beneficiary firms have to achieve a domestic value addition of at least 25% and incur the mandatory investment Rs.225 crore /GWh within 2 Years (at the Mother Unit Level) and raise it to 60% domestic value addition within 5 Years, either at Mother Unit, in-case of an Integrated Unit, or at the Project Level, in-case of “Hub & Spoke” structure.
    • The scheme will help in achieving manufacturing capacity of Fifty (50) Giga Watt Hour (GWh) of ACC and 5 GWh of “Niche” ACC with an outlay of Rs.18,100 crore.

    About ACC

    • ACCs are the new generation of advanced storage technologies that can store electric energy either as electrochemical or as chemical energy and convert it back to electric energy as and when required.

    Benefits of the scheme

    • Setup a cumulative 50 GWh of ACC manufacturing facilities in India under the Programme.
    • Direct investment of around Rs.45,000 crore in ACC Battery storage manufacturing projects.
    • Facilitate demand creation for battery storage in India.
    • Facilitate Make-ln-lndia: Greater emphasis upon domestic value-capture and therefore reduction in import dependence.
    • Net savings of Indian Rs. 2,00,000 crore to Rs.2,50,000 crore on account of oil import bill reduction during the period of this Programme due to EV adoption as ACCs manufactured under the Programme is expected to accelerate EV adoption.
    • The manufacturing of ACCs will facilitate demand for EVs, which are proven to be significantly less polluting.
    • As India pursues an ambitious renewable energy agenda, the ACC program will be a key contributing factor to reduce India’s Green House Gas (GHG) emissions which will be in line with India’s commitment to combat climate change.
    • Import substitution of around Rs.20,000 crore every year.
    • The impetus to Research & Development to achieve higher specific energy density and cycles in ACC.
    • Promote newer and niche cell technologies.

    • Enabling agricultural NBFCs to access low-cost capital and deploy a ‘phygital’ (physical + digital) model for achieving better long-term digital outcomes.
    • Digitizing land records will also provide a major boost to the sector.
    • To make city transit seamlessly accessible to all with minimal crowding and queues, leveraging existing smartphones andcontactless cards, and aim for an inclusive, interoperable, and fully open system such as that of the London ‘Tube’.

  • NASA’s OSIRIS-REx begins journey back from asteroid

    On May 11, NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft will depart asteroid Bennu, and start its two-year-long journey back to Earth.

    About OSIRIS-REx

    • OSIRIS-REx is NASA’s first mission to visit a near-Earth asteroid, survey its surface and collect a sample from it.
    • The mission was launched in 2016, it reached its target in 2018 and since then, the spacecraft has been trying to match the velocity of the asteroid using small rocket thrusters.
    • It also utilised this time to survey the surface and identify potential sites to take samples.
    • In October 2020, the spacecraft briefly touched asteroid Bennu, from where it collected samples of dust and pebbles. 
    • Once the surface was disturbed, the spacecraft’s robotic arm captured some samples.
    • The spacecraft’s engineers have also confirmed that shortly after the spacecraft made contact with the surface, it fired its thrusters and “safely backed away from Bennu”.

    About Bennu

    • Bennu is considered to be an ancient asteroid that has not gone through a lot of composition-altering change through billions of years, which means that below its surface lie chemicals and rocks from the birth of the solar system.
    • Around 20-40 percent of Bennu’s interior is empty space and scientists believe that it was formed in the first 10 million years of the solar system’s creation, implying that it is roughly 4.5 billion years old.
    • Bennu is a B-type asteroid, implying that it contains significant amounts of carbon and various other minerals.
    • Because of its high carbon content, the asteroid reflects about four percent of the light that hits it, which is very low when compared with a planet.
    • Bennu is named after an Egyptian deity.
    • The asteroid was discovered by a team from the NASA-funded Lincoln Near-Earth Asteroid Research team in 1999.

  • What is 2-deoxy-D-glucose (2-DG) and is it effective against Covid?

    About the drug

    • DRDO’s new anti-Covid oral drug, 2-deoxy-D-glucose (2-DG), was recently granted emergency use approval by the Drug Controller General of India (DCGI).
    •  2-DG halts the spread of COVID-19 inside the body cells.
    • Clinical trial results have shown that this molecule helps in faster recovery of hospitalised patients and reduces supplemental oxygen dependence.
    • In efficacy trends, the patients treated with 2-DG showed faster symptomatic cure than Standard of Care (SoC) on various endpoints.
    • A significantly favourable trend (2.5 days difference) was seen in terms of the median time to achieving normalisation of specific vital signs parameters when compared to SoC.

    How 2-DG reduces dependence on oxygen

    • The 2 DG drug, like glucose, spreads through the body, reaches the virus-infected cells and prevents virus growth by stopping viral synthesis and destroys the protein’s energy production.
    • The drug also works on virus infection spread into lungs which help us to decrease patients dependability on oxygen.

     

  • A TRIPS waiver is useful but not a magic pill

    The article highlights the challenges countries could face despite the patent waiver for Covid-19 vaccine.

    TRIPS waiver for Covid-19 vaccine

    • The United States has finally relented and declared its support for a temporary waiver of the Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement for COVID-19 vaccines at the World Trade Organisation (WTO).
    • Hopefully, the U.S.’s decision would cause other holdouts like Canada and the European Union to give up their opposition.
    • While the U.S.’s decision is to be welcomed, the devil would be in the details.

    The challenges after waiver

    1) Conditions of the waiver

    •  If the experience of negotiating such waivers, especially on TRIPS, were anything to go by, it would be too early to celebrate.
    • In the aftermath of the HIV/AIDS crisis the WTO adopted a decision in 2003 waiving certain TRIPS obligations to increase the accessibility of medicines.
    • However, this waiver (later incorporated as Article 31 bis in the TRIPS agreement) was subject to several stringent requirements such as the drugs so manufactured are to be exported to that nation only; the medicines should be easily identifiable through different colour.
    • Given these cumbersome requirements, hardly any country, in the last 17 years, made effective use of this waiver.

    2) Countries will protect the interest of pharma companies

    •  India and South Africa proposed a waiver not just on vaccines but also on medicines and other therapeutics and technologies related to the treatment of COVID-19.
    • So, the U.S. has already narrowed down the scope of the waiver considerably by restricting it to vaccines.
    • Medicines useful in treating COVID-19 and other therapeutics must be also included in the waiver.
    • While the U.S. would not like to be seen as blocking the TRIPS waiver and attracting the ire of the global community, make no mistake that it would resolutely defend the interests of its pharmaceutical corporations.

    3) Lack of access to technology

    • The TRIPS waiver would lift the legal restrictions on manufacturing COVID-19 vaccines.
    • But it would not solve the problem of the lack of access to technological ‘know-how’ related to manufacturing COVID-19 vaccines.
    • Waiving IP protection does not impose a legal requirement on pharmaceutical companies to transfer or share technology.
    • While individual countries may adopt coercive legal measures for a forced transfer of technology, it would be too draconian and counterproductive.
    • Therefore, governments would have to be proactive in negotiating and cajoling pharmaceutical companies to transfer technology using various legal and policy tools including financial incentives.

    4) Domestic IP regulation

    • While a TRIPS waiver would enable countries to escape WTO obligations, it will not change the nature of domestic IP regulations.
    • Therefore, countries should start working towards making suitable changes in their domestic legal framework to operationalise and enforce the TRIPS waiver.
    • In this regard, the Indian government should immediately put in place a team of best IP lawyers who could study the various TRIPS waiver scenarios and accordingly recommend the changes to be made in the Indian legal framework.

    Conclusion

    Notwithstanding the usefulness of the TRIPS waiver, it is not a magic pill. It would work well only if countries simultaneously address the non-IP bottlenecks.

  • Power generation from renewables increased despite drop in new capacity

    What the data from Central Electricity Authority says

    • The total power generation from renewable energy sources including solar, wind, bagasse, biomass, small hydro and others stood at 147.25 billion units in FY21 compared with 138.34 billion units in FY20.
    • This is an increase of six per cent, according to data from the Central Electricity Authority.
    • All other key segments such as thermal, hydro and nuclear have reported a drop in power generation during FY21.
    • This is despite a significant drop in new capacity addition in the renewables sector in Covid-battered 2020-21.
    • The total power generation from renewable energy sources (including solar, wind, bagasse, biomass, small hydro and others) stood at 147.25 billion units in FY21 compared with 138.34 billion units in FY20.
    • In FY21, total power generation from thermal, hydro, nuclear and renewables stood at 1372.9 billion units compared with 1383.33 billion units in FY20.

    Factors responsible

    • There are several factors working for an increase in generation by renewable sources.
    • The first factor is the thrust given to renewable energy by the government.
    • Second is the growing environmental awareness in the country, and the potential growth is driving more capacity creation here.
    • Third, getting in investment, — both domestic and foreign, is easier as this is an attractive area for them.

  • Environment Appraisal Committee allows Great Nicobar plan to advance

    About the Great Nicobar plan

    • The Environment Appraisal Committee (EAC) – Infrastructure I of the Ministry of Environment, Forest and Climate Change (MoEFCC) has flagged serious concerns about NITI Aayog’s ambitious project for Great Nicobar Island.
    • The EAC was responding to ‘pre-feasibility’ report, ‘Holistic Development of Great Nicobar Island at Andaman and Nicobar Islands’.
    • The report is prepared for the NITI Aayog by the Gurugram-based consulting agency.
    • The proposal includes an international container transshipment terminal, a greenfield international airport, a power plant and a township complex spread over 166 sq. km. and is estimated to cost ₹75,000 crore.
    • The committee has, however, removed the first hurdle faced by the project.
    • It has recommended it “for grant of terms of reference (TOR)” for Environmental Impact Assessment (EIA) studies, which in the first instance will include baseline studies over three months.

    What the EAC said

    • The committee noted that the site selection for the port had been done mainly on technical and financial criteria, ignoring the environmental aspects.
    • It has now asked for an independent study/ evaluation for the suitability of the proposed port site with specific focus on Leatherback Turtle, Nicobar Magapode and Dugong.
    • It highlighted the need for an independent assessment of terrestrial and marine biodiversity, a study on the impact of dredging, reclamation and port operations, including oil spills.
    • It has also highlighted the need for studies of alternative sites for the port with a focus on environmental and ecological impact,  analysis of risk-handling capabilities, a seismic and tsunami hazard map, a disaster management plan, an assessment of the cumulative impact, and a hydro-geological study to assess impact on round and surface water regimes.
    • The committee has also asked for details of the corporate environment policy of the implementing agency — whether the company has an environment policy, a prescribed standard operating procedure to deal with environmental and forest violations, and a compliance management system.
