  • Rare white-bellied heron spotted in Arunachal Pradesh

    About the bird

    • The white-bellied heron is categorised as ‘critically endangered’ in International Union for Conservation of Nature (IUCN) Red Data Book.
    • It is listed in Schedule IV in the Wildlife Protection Act, 1972.
    • It is one of the rarest birds in the world and is found only in Bhutan, Myanmar and the Namdapha Tiger Reserve in Arunachal Pradesh.
    • It had also been recorded in the adjacent Kamlang Tiger Reserve in Lohit district in camera trap images.

    Significance of recent sighting

    • The recent sighting at a height of 1,200 metres above sea level is a first at such a higher elevation in India.
    • The presence of nesting sites within this area is a positive sign for the future habitat as the breeding season of the white-bellied heron starts in February and lasts till June.
    • It is great news that the critically endangered bird is establishing new habitat beyond its traditional range.

  • Delhi’s air quality deteriorates, again

    Air quality to oscillate between poor to very poor

    • Delhi’s air quality deteriorated from ‘moderate’ to ‘poor’ and ‘very poor’ on April 29.
    • It will be oscillating between ‘poor’ and ‘very poor’ for the next three days, according to the SAFAR-System of Air Quality and Weather Forecasting and Research.
    • Delhi’s air typically worsens in October-November and improves by March-April.

    What is the cause

    • Current weather conditions are not unfavourable, unlike in winter.
    • Hence, apart from local emissions, the deterioration in air quality is being attributed to an increase in fire counts, mostly due to burning of wheat crop stubble in northern India.
    • Deteriorating air quality is worrying amid an increasing number of novel coronavirus disease (COVID-19) and deaths.

    Quality classification

    • An AQI between 0-50 is considered ‘good.
    • An AQI between 51-100 is considered satisfactory.
    • An AQI between 101-200 is considered moderate.
    • An AQI between 201-300 is considered poor.
    • An AQI between 301-400 is considered very poor.
    • An AQI between 401-500 is considered severe.
    • Above 500 is the ‘severe-plus’ or ‘emergency’ category.

  • Hottest planet in the known universe discovered

    About the plane

    • TOI-1431b, also known as MASCARA-5b, was found 490 light-years from Earth and could be the hottest planet in the known universe.
    • Researchers at the University of Southern Queensland’s Centre for Astrophysics in Toowoomba led the global team that made the discovery.
    • NASA’s Training Exoplanet Survey Satellite first flagged TOI-1431b as a possible planet in late 2019.
    • Dayside temperature reaches approximately 2700 degrees celcius and nightside temperature approaches approximately 2300 degrees celcius – no life could survive in its atmosphere.
    • This temperature is significantly greater than the melting point of most metals, many of which will turn to liquid at under 2000 degrees celcius.
    • Titanium melts at 1670 degrees, platinum at 1770 degrees, and stainless steel at between 1375 and 1530 degrees.

    Planet with a retrograde orbit

    • These types of planets, known as ultra-hot Jupiters, are rarely discovered but this particular one is even more unusual due to its retrograde orbit.
    • In our Solar System, all the planets orbit in the same direction that the Sun rotates and they’re all along the same plane.
    • This new planet’s orbit is tilted so much that it is actually going in the opposite direction to the rotation of its host star.

  • [pib] Seven Indian Navy Ships Deployed for Op Samudra Setu II

    Operation Samudra Setu II

    • In support of the nation’s fight against Covid-19 and as part of operation ‘Samudra Setu II’,  seven Indian Naval ships have been deployed for shipment of liquid medical oxygen-filled cryogenic containers and associated medical equipment from various countries.
    • Indian Navy also has the surge capability, to deploy more ships when the need arises to further nation’s fight against COVID-19.
    • It is pertinent that the ships are combat ready and capable of meeting any contingency in keeping with the attributes of versatility of sea power.

    Operation Samudra Setu I

    • It may be recalled that Operation Samudra Setu was launched last year by the Navy and around 4000 Indian citizens stranded in neighbouring countries, amidst COVID 19 outbreak, were successfully repatriated back to India.

  • No mass nesting of Olive Ridley turtles at Rushikulya in Odisha this year

    No mass nesting this year

    • The annual spectacle of the mass nesting of millions of Olive Ridley sea turtles near the Rushikulya river mouth in Odisha is likely to be missed this year, as the time for it is almost over.
    • It’s been around one month since the mass nesting of last year.
    • If they do skip the beach, this won’t be the first time.
    • In 2002, 2007, 2016 and 2019, the turtles had not shown up at Rushikulya.
    • The Rushikulya river mouth is considered the second-biggest rookery in India after Gahirmatha.
    • Mass nesting in the Gahirmatha marine sanctuary occurred from March 9-23, 2021 and over 349,000 eggs were laid during this period.

    What could explain the miss in mass nesting

    • It is a natural phenomenon. During some years, they did not turn up for mass nesting even though a huge number had congregated in the sea.
    • Beach erosion might be one of the causes for the turtles staying away this year.

  • Don’t worry about the deficit

    The devastation caused by the second wave calls for the government to shed its worry over the fiscal deficit. The article deals with this issue.

    Role of fiscal policy to support economy through second wave

    • As India battles to contain the surge in COVID-19 cases, several states have already imposed severe restrictions at the local level.
    • The services sector has been hit the most as a consequence of these lockdowns and it would be difficult for India to deliver on this optimistic growth projection.
    • Against this background, the role fiscal policy can play to support the economy needs consideration.
    • The monetary policy is already accommodative and may not have enough room to further boost the economy.
    • With headline as well as core inflation inching up in recent months, the RBI may not be in a position to further cut the policy rate.
    •  As per the latest Union Budget, the fiscal deficit is estimated to moderate from 9.5 per cent of GDP in FY21 to 6.8 per cent of GDP in FY22.
    • This expected decline in fiscal deficit is not on account of lower fiscal spending but because of expectations of sharper revenue growth.
    • The revenue receipts are estimated to grow by 15 per cent and fiscal spending by 1 per cent this financial year.
    • With the debt to GDP ratio already more than 90 per cent, additional fiscal expansion will not be an easy choice for the government.

    Government need to create fiscal space

    • Extraordinary times call for extraordinary measures and the government will have to find ways to create fiscal space.
    • This has become especially important as the economy is yet to shrug off the impact of the previous lockdown.
    • Under these difficult circumstances, immediate measures must aim at providing the requisite social safety net to the poor and the vulnerable.
    • The central government has already announced it will distribute an additional five kg of grain to the 800 million beneficiaries of the National Food Security Act, which is welcome.
    • However, given the unprecedented uncertainty brought about by this COVID wave, the ration support under the PDS should be raised further.
    • The government should also consider transferring cash to the bank accounts of the poor, just as it did last time.
    • This becomes important as MGNREGA  may not provide the safety cushion that it is indeed to as long as lockdown measures remain in place.
    • The best stimulus perhaps would be to provide free vaccinations to the population as the benefits of faster and wider vaccine coverage more than outweighs its monetary cost.
    •  Immunisation is a public good. As we get over this crisis, the government must increase its outlay on physical and human health infrastructure.

    How to finance additional cost?

    •  Part of this additional cost may be financed by reducing non-essential government expenditures and use it for COVID-related expenditure.
    • The government may need to resort to additional borrowings from the market than budgeted earlier.
    • The RBI may allow inflation above the upper bound of 6 per cent only in the short run.
    • The plausible rise in interest rates may also be crucial to prevent capital outflows, given the global “economic outlook” when the US economy adopts an easy monetary policy combined with a huge fiscal stimulus.

    Conclusion

    The government should not be deterred by a worsening fiscal deficit in the short run as the additional growth that it generates may make debt consolidation easier when things normalise.

  • [pib] DRDO conducts maiden trial of Python-5 Air to Air Missile

    Tejas adds Python-5 in its capacity

    • Tejas, India’s indigenous Light Combat Aircraft, added the 5th generation Python-5 Air-to-Air Missile (AAM) in its air-to-air weapons capability on April 27, 2021.
    • Trials were also aimed to validate enhanced capability of already integrated Derby Beyond Visual Range (BVR) AAM on Tejas.
    • The test firing at Goa completed a series of missile trials to validate its performance under extremely challenging scenarios.
    • The trials met all their planned objectives.
    • The missiles were fired from Tejas aircraft of Aeronautical Development Agency (ADA) flown by Indian Air Force (IAF) Test pilots.
    • The successful conduct was made possible with years of hard work by the team of scientists, engineers and technicians from ADA and HAL-ARDC along with admirable support from CEMILAC, DG-AQA, IAF PMT, NPO (LCA Navy) and INS HANSA.

  • Major oil and gas producers form Net Zero Producers’ Forum

    About the Net Zero Producers’ forum

    • Five of the world’s major oil and gas producers are working together to ‘develop pragmatic net-zero emission strategies’.
    • Qatar, the US, Saudi Arabia, Canada and Norway, collectively responsible for 40% of global oil and gas production, will come together to form a cooperative forum that will develop pragmatic net zero-emission strategies.
    • Energy producers are faced with unique responsibilities to furnish the world with energy but the climate crisis requires serious leadership and a strong alliance to deliver a path to net-zero.

    Strategies and technologies

    • The Net Zero Producers’ Forum will consider strategies and technologies which include methane abatement, circular carbon economy approach, development and deployment of clean energy and carbon capture and storage technologies, diversification from reliance on hydrocarbon revenues etc.

  • Limited sops make scrappage policy for vehicles unattractive

    Why the Vehicle Scrappage Policy is unattractive

    • The policy proposes to de-register vehicles that fail fitness tests or are unable to renew registrations after 15-20 years of use.
    • Limited incentives and poor cost economics for trucks in the Vehicle Scrappage Policy, coupled with lack of addressable volumes for other segments is unlikely to drive freight transporters to replace their old vehicles with new ones, said a Crisil report.
    • Though the scrappage volume of buses, PVs and two-wheelers is expected to be limited as well, the policy’s impact on new commercial vehicle (CV) sales could be sizeable, based on addressable volume, ratings agency Crisil Research said in its report.
    • The potential benefit from scrapping a 15-year-old, entry-level small car will be â‚č70,000, whereas its resale value is around â‚č95,000. That makes scrapping unattractive, Crisil said in the report.

  • Clean energy innovation slowing, report warns

    Major findings of the report

    • It is a joint report titled “Patents and the energy transition” released by the European Patent Office and the International Energy Agency.
    • The average annual growth rate of patents for low carbon emissions technologies has fallen to 3.3 percent since 2017, the rate was 12.5 percent in the period 2000-2013.
    • The report found that around 35 percent of the cumulative CO2 emissions reductions needed to shift to a sustainable path to reach net-zero emissions by 2070 are still currently at the prototype or demonstration phase.
    • The report found that energy efficiency and fuel-switching technologies remained at the top of patent activities, accounting for about 60 percent of the total.

    Shifting trend withing renewable

    • Patent activity in renewable energy technologies such as wind and solar has been in decline for nearly a decade however, and represented just 17 percent of the total in 2019, report found.
    • The key driver of patent growth since 2017 has been innovation in cross-cutting technologies such as batteries, hydrogen and smart grids, along with carbon-capture, utilisation and storage.
