GS Paper: GS3

  • RBI extends Ways and Means credit for States, UTs to Sept

    About Ways and Means credit

    • Simply put, it is a facility for both the Centre and states to borrow from the RBI.
    • WMAs are temporary advances given by the RBI to the government to tide over any mismatch in receipts and payments.
    • Section 17(5) of the RBI Act, 1934 authorises the central bank to lend to the Centre and state governments subject to their being repayable “not later than three months from the date of the making of the advance”.

    Extension of the scheme

    • The RBI decided to continue with the existing interim Ways and Means Advances (WMA) scheme limit of ₹51,560 crore for all States/ UTs shall for six months given the prevalence of COVID-19.
    • Based on the recommendations of the Advisory Committee on WMA to State Governments, 2021 — chaired by Sudhir Shrivastava — the RBI had revised the WMA Scheme of States and Union Territories (UTs).
    • The WMA limit arrived at by the Committee based on total expenditure of States/ UTs, works out to ₹47,010 crore. 

    What RBI said about SDR

    • The RBI further said Special Drawing Facility (SDF) availed by state governments and UTs will continue to be linked to the quantum of their investments in marketable securities issued by the Government of India.
    • The net annual incremental investments in Consolidated Sinking Fund (CSF) and Guarantee Redemption Fund (GRF) will continue to be eligible for availing of SDF, without any upper limit.
    • CSF and GRF are reserve funds maintained by some State Governments with the Reserve Bank of India.

  • Brucellosis: Preventive measures launched

    Health and Animal Husbandry teams have launched preventive measures and initiated an epidemiological investigation, after one case of brucellosis, was confirmed in a prisoner.

    • The infection is passed on to humans through the ingestion of unpasteurized milk and milk products or contact with animal secretions.

    Brucellosis:

    • Brucellosis is a bacterial disease that mainly infects cattle, swine, goats, sheep and dogs.
    • Humans can get infected if they come in direct contact with infected animals or by eating or drinking contaminated animal products or by inhaling airborne agents.
    • According to the WHO, most cases of the disease are caused by ingesting unpasteurised milk or cheese from infected goats or sheep.

    Symptoms:

    • Fever, sweats, malaise, anorexia, headache and muscle pain
    • While some signs and symptoms can last for long periods of time, others may never go away.
    • These include recurrent fevers, arthritis, swelling of the testicles and scrotum area, swelling of the heart, neurologic symptoms, chronic fatigue, depression and swelling of the liver or spleen.
    • Human to human transmission of the virus is rare.

  • [pib] Satellite-based real-time monitoring of Himalayan glacial catchments

    Melting of glaciers in Himalaya and GLOFs

    • The Himalayan region is home to the largest ice mass outside of the planet’s Polar Regions.
    • The glaciers in the Himalayas are melting at a faster rate creating new lakes and expanding the existing ones.
    • The rising temperatures and extreme precipitation events make the region increasingly prone to a variety of natural hazards, including devastating glacial lake outburst floods (GLOFs).
    • GLOFs occur when either a natural dam containing a glacial lake bursts or when the lake’s level suddenly increases and overflows its banks, leading to catastrophic downstream destruction.
    • However, the remote, challenging Himalayan terrain and the overall lack of cellular connectivity throughout the region have made the development of early flood warning systems virtually impossible.
    • In their recent work the Scientists point out that the surge of meltwater in mountain streams is most commonly caused by cloud-burst events during the monsoon season (June–July–August) time frame.

    Satelitte-based real-time monitoring

    • Satellite-based real-time monitoring of Himalayan glacial catchments would improve understanding of flood risk in the region and help inform an early flood warning system that could help curb disaster and save human lives, says a recent study.
    • This should be the future strategy to reduce loss of human lives during glacial lake outburst floods (GLOF), said a study carried out by scientists from IIT Kanpur.
    • The IIT Kanpur team suggests that efforts to help mitigate GLOF events in the future should include the creation of a network of satellite-based monitoring stations that could provide in situ and real-time data on GLOF risk.
    • The integration of monitoring devices with satellite networks will not only provide telemetry support in remote locations that lack complete cellular connectivity but will also provide greater connectivity in coverage in the cellular dead zones in extreme topographies such as valleys, cliffs, and steep slopes.

  • [pib] Drone use permission for feasibility study of Covid-19 vaccine delivery

    Conditional drone use exemption for vaccine delivery

    • Ministry of Civil Aviation (MoCA) and Directorate General of Civil Aviation (DGCA) have granted conditional exemption to the Indian Council of Medical Research (ICMR).
    • The exemption is granted for conducting feasibility study of Covid-19 vaccine delivery using drones in collaboration with IIT Kanpur.
    • The permission exemption is valid for a period of one year or until further orders.

    Entities using drone on conditional drone use exemption basis

    • Conditional drone use exemption has been granted to the below entities for said purposes:
    • Nagar Nigam of Dehradun, Haldwani, Haridwar & Rudrapur for preparation of GIS based property database & electronic tax register.
    • West Central Railway, (WCR) Kota for train accident site & maintaining safety & security of the railway assets.
    • West Central Railway, (WCR) Katni for train accident site & maintaining safety & security of the railway assets.

  • Eastern India most vulnerable to climate change, says study

    About the report

    • Published this week, the report on ‘Climate vulnerability assessment for adaptation planning in India using a common framework’ was conducted in 2019-2020 across 29 States.
    • It was part of a capacity building programme under the National Mission on Sustaining the Himalayan Ecosystem and National Mission on Strategic Knowledge for Climate Change.
    • The report was prepared by IISc, IIT-Mandi and IIT-Guwahati.

    Major findings

    • Along with Chhattisgarh in central India, Jharkhand, Mizoram, Odisha, Assam, Bihar, Arunachal Pradesh, and West Bengal are the eight most vulnerable States.
    • These eight most vulnerable States require prioritisation of adaptation interventions.
    • Jharkhand, with the highest vulnerability indices VI of 0.674, topped the list of States most vulnerable to climate change.
    • The major drivers for the vulnerability of all the States included lack of forest area per 1,000 rural population, lack of crop insurance, marginal and small operational land holding, low density of health workers, low participation of women in the workforce, yield variability of food grains, and a high proportion of the population below the poverty line.
    • Tamil Nadu and Kerala are among seven States that are the least vulnerable but there’s more to it meets the eye.
    • However, the vulnerability indices (VIs) for these seven States range from the lowest of 0.419 for Maharashtra to 0.468 for Uttarakhand, which is on the higher side.

  • India-U.S. climate partnership

    Leaders Summit on Climate

    • Leaders Summit on Climate included 40 heads of state and government.
    • At the summit, President of the United State and Indian Prime Minister launched the ‘India-U.S. climate and clean energy Agenda 2030 partnership’. 
    • The goal of the partnership are given below:
    • 1) Mobilise finance and speed clean energy deployment.
    • 2) Demonstrate and scale innovative clean technologies needed to decarbonise sectors, including industry, transportation, power, and buildings.
    • 3) Build capacity to measure, manage, and adapt to the risks of climate-related impacts.

    India’s progress on NDC

    • Despite development challenges, India has taken many bold steps on clean energy, energy efficiency, afforestation and bio-diversity.
    • That is among the few countries whose NDCs are 2-degree-Celsius compatible.
    •  India is targeting a 2030 GDP emissions intensity ( i.e., volume of emissions per unit of GDP) that is 33%-35% below 2005 levels.
    • It also seeks to have 40% of power generated from non-fossil fuel sources by 2030.
    •  India’s per capita carbon footprint is 60% lower than the global average.

  • Global Energy Review 2021 report

    Initial estimates for 2020 energy demand and CO2 emission was released recently in an annual report Global Energy Review by International Energy Agency (IEA).

    https://www.world-nuclear-news.org/BlankSiteASPX/media/WNNImported/mainimagelibrary/corporate%20branded/Global-Energy-Review-2021-(IEA).jpg?ext=.jpg

    • The Global Energy Review is annual update on the latest trends in world energy and CO2 emissions.
    • It covers all the main fuels and technologies, providing insights across regions, economies and countries.

    Highlights of the report:

    • Global energy-related carbon dioxide (CO2) emissions are on course to surgeby 1.5 billion tonnes in 2021 driven by in the resurgence of coal use in the power sector.
      • The second-largest increase in history.
      • This would be the biggest annual rise in emissions since 2010, during the carbon-intensive recovery from the global financial crisis.
    • CO2 emissions will increase by almost five per cent in 2021 to 33 billion tonnes.
      • The key driver is coal demand, which is set to grow by 4.5 per cent, surpassing its 2019 level and approaching its all-time peak from 2014, with the electricity sector accounting for three-quarters of this increase.
    • Global energy demand is set to increase by 4.6 per cent in 2021, led by emerging markets and developing economies, pushing it above its 2019 level.
    • Demand for all fossil fuels is on course to grow significantly in 2021, with both coal and gas set to rise above their 2019 levels.
    • Oil is also rebounding strongly but is expected to stay below its 2019 peak, as the aviation sector remains under pressure.
      • More than 80 per cent of the projected growth in coal demand in 2021 is set to come from Asia, led by China.
    • Electricity generation from renewables is set to leap by over eight per cent in 2021.
    • The biggest contribution to that growth comes from solar and wind.
      • Electricity generation from wind is projected to grow by 275 terawatt-hours, or around 17 per cent, from last year.
      • Electricity generation from solar PV is expected to increase by 145 terawatt-hours, up almost 18 per cent from last year.
      • Their combined output is on track to reach more than 2800 terawatt-hours in 2021.
    • Renewables are set to provide 30 per cent of electricity generationworldwide in 2021.
    • China is expected to account for almost half of the global increase in electricity generation from renewables, followed by the US, the European Union and India.

  • India ranks 87th in global energy transition index

    India has been ranked at the 87th position among 115 countries in the Energy Transition Index (ETI).

    • The latest report is based on a revised ETI methodology that takes into account recent changes in the global energy landscape and the increasing urgency of climate change action.
    • 92 out of 115 countries tracked on the ETI increased their aggregate score over the past 10 years, which affirms the positive direction and steady momentum of the global energy transition

    Highlights of the report:

    • The top 10 countries in the index are Western and Northern European countries.
    • Sweden is in the first position followed by Norway (2nd) and Denmark (3rd).
    • Other countries in the top 10 are Switzerland (4), Austria (5), Finland (6), the United Kingdom (7), New Zealand (8), France (9) and Iceland (10).
    • China (68) and India (87), which collectively account for a third of global energy demand, have both made strong improvements over the past decade, despite coal continuing to play a significant role in their energy mix.
      • “China”s improvements primarily result from reducing the energy intensity of the economy, gains in decarbonising the energy mixthrough the expansion of renewables and strengthening the enabling environment through investments and infrastructure.
    • Zimbabwe is the last ranked country.

    India specific highlights:

    • India has been ranked at the 87th position among 115 countries.
    • India has targeted improvements through subsidy reforms and rapidly scaling energy access, with a strong political commitment and regulatory environment for the energy transition.

    About the Energy Transition Index (ETI):

    • ETI is a report from World Economic Forum (WEF).
    • It is an annual ranking.
    • The index tracks nations on the current performance of their energy systems across various aspects.
    • The index benchmarks 115 countries on the current performance of their energy systems across three dimensions :
      1. Economic development and growth
      2. Environmental sustainability
      3. Energy security and access indicators — and their readiness to transition to secure, sustainable, affordable, and inclusive energy systems.

  • A fresh push for green hydrogen

    Green hydrogen could help significantly in India’s transition to low carbon future. However, there are several challenges in ramping up its manufacturing. The article suggests measures to deal with these challenges.

    Increasing the production of green hydrogen

    • India will soon join 15 other countries in the hydrogen club as it prepares to launch the National Hydrogen Energy Mission (NHEM). 
    • India will soon join 15 other countries in the hydrogen club as it prepares to launch the National Hydrogen Energy Mission (NHEM). 
    • In 2030, according to an analysis by the Council on Energy, Environment and Water (CEEW), green hydrogen demand could be up to 1 million tonnes in India across application in sectors such as ammonia, steel, methanol, transport and energy storage. 

    Dealing with challenges

    Several challenges in scaling up to commercial-scale operations persist. Following are five recommendations.

    1) Decentralise green hydrogen production

    • Decentralised hydrogen production must be promoted through open access of renewable power to an electrolyser (which splits water to form H2 and O2 using electricity).
    • Currently, most renewable energy resources that can produce low-cost electricity are situated far from potential demand centres.
    • Producing oxygen at such locations and then shipped, it would significantly erode the economics of it.
    • A more viable option would be wheeling electricity directly from the solar plant.
    • However, the electricity tariffs could double when supplying open-access power across State boundaries.
    • Therefore, operationalising open access in letter and spirit, as envisioned in the Electricity Act, 2003, must be an early focus.

    2)  Ensure access to round-the-clock renewable power

    • To minimise intermittency associated with renewable energy, for a given level of hydrogen production capacity, a green hydrogen facility will store hydrogen to ensure continuous hydrogen supply.
    • Therefore, as we scale up to the target of having 450 GW of renewable energy by 2030, aligning hydrogen production needs with broader electricity demand in the economy would be critical.

    3) Blending green hydrogen in industrial sector

    • We must take steps to blend green hydrogen in existing processes, especially the industrial sector.
    • Improving the reliability of hydrogen supply by augmenting green hydrogen with conventionally produced hydrogen will significantly improve the economics of the fuel.
    • This will also help build a technical understanding of the processes involved in handling hydrogen on a large scale.

    4) Facilitate investment

    • Policymakers must facilitate investments in early-stage piloting and the research and development needed to advance the technology for use in India.
    • The growing interest in hydrogen is triggered by the anticipated steep decline in electrolyser costs.
    • Public funding will have to lead the way, but the private sector, too, has significant gains to be made by securing its energy future.

    5) Focus on domestic manufacturing

    •  India must learn from the experience of the National Solar Mission and focus on domestic manufacturing.
    • Establishing an end-to-end electrolyser manufacturing facility would require measures extending beyond the existing performance-linked incentive programme.
    • India needs to secure supplies of raw materials that are needed for this technology.
    • Further, major institutions like the DRDO, BARC and CSIR laboratories have been developing electrolyser and fuel-cell technologies.

    Consider the question “Even before it has reached any scale, green hydrogen has been anointed the flag-bearer of India’s low-carbon transition. In lights of this, examine the challenges India faces in scaling up its green hydrogen production and suggest the ways to deal with these challenges.”

    Conclusion

    Hydrogen may be lighter than air, but it will take some heavy lifting to get the ecosystem in place.

  • Plasmid

    • Scientists have developed a Covid-19 vaccine that could offer protection against not only existing and future strains of the SARS-CoV-2 coronavirus.
    • The vaccine costs $1 a dose. It uses the plasmid of E-coli bacteria to produce the vaccine.
    • A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently.

    • They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms.
