1-D Simulation Code to Study Earth’s Magnetosphere

Why in News

Scientists at the Indian Institute of Geomagnetism (IIG) have developed a generalized one-dimensional fluid simulation code capable of studying a wide spectrum of coherent electric field structures in near-earth plasma environments or earth’s magnetosphere.

• The developed simulation code is expected to help in planning of future space missions.

Key Points

• Formation of Earth’s Magnetosphere:
  
  • Sun is the major source of plasma deposition in space around the Earth. Thus, the Sun forces some of its plasma towards the earth in the form of the solar wind.
    
    • Plasma is the most common state of matter in the universe as a whole.It consists of a gas of ions and free electrons.
  • The speed of solar wind varies between 300 to 1500 km/s, which carries with it a solar magnetic field, called the Interplanetary Magnetic Field (IMF).
  • The interaction of the IMF with the earth’s magnetic field creates the magnetosphere of the earth.
  • The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind - the constant flow of charged particles streaming off the sun.
• Regions of the Earth’s Magnetosphere:
  
  • The schematic diagram of Earth’s magnetosphere shown consists of different regions namely,
    
    1. Bow shock : It occurs when the magnetosphere of an Earth interacts with the nearby flowing ambient plasma such as the solar wind.
    2. Magnetosheath: It is the region of space between the magnetopause and the bow shock of a planet's magnetosphere.
    3. Magnetopause : It is the boundary between the planet's magnetic field and the solar wind.
    4. Northern tail lobe : The magnetosphere of the earth contains two lobes, referred to as the northern and southern tail lobes. Magnetic field lines in the northern tail lobe point towards the earth.
    5. Southern tail lobe: The magnetic field lines in the southern tail lobes point away from the earth. Usually, the tail lobes are almost empty, with few charged particles opposing the flow of the solar wind.
    6. Plasmasphere : The plasmasphere, or inner magnetosphere, is a region of the Earth's magnetosphere consisting of low energy (cool) plasma.
    7. Solar winds: It is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.
• Significance of Study of Plasma Processes:
  
  • The plasma processes have the ability to hamper the working of a number of satellites that have been placed in orbit in the magnetospheric region.
    
    • However, the morphology of these plasma processes changes over space and time. These changes can be ideally deciphered only through computer simulations.
  • The study will help advance the knowledge of plasma waves, instabilities, and coherent effects associated with wave-particle interactions that are useful in planning future space missions.
  • It can also lead to precisely controlled fusion laboratory experiments for ever-expanding energy needs of humanity.

Drop in FPI Outflows

Why in News

According to recent data from Central Depository Services Limited (CDSL), the Foreign Portfolio Investors (FPIs) have significantly reduced the pace of outflows from the equity and debt market in April, 2020, after a record net outflow of Rs 1,18,203 crore in March 2020.

Key Points

• FPIs sold a net of Rs 6,883 crore from the equities market and net holdings worth Rs 12,551 crore from the debt market in April.
  
  • In equity market shares are issued and traded, either through exchanges or over-the-counter markets (i.e directly). It is also known as the stock market.
  • The debt market is the market where debt instruments are traded.
  • Debt instruments are instruments that require a fixed payment to the holder, usually with interest. E.g. bonds (government or corporate) and mortgages.
• However, they invested a net of Rs 4,032 crore in debt Voluntary Retention Route (VRR) scheme.
  
  • VRR scheme allows FPIs to participate in repo transactions and also invest in exchange traded funds that invest in debt instruments.
• Outflows have continued due to uncertainty surrounding economic conditions caused by Covid-19 lockdown and investors are cautious. However, the pessimism also continues to grip the markets.
• So far, India has been able to contain the Covid-19 pandemic from spreading aggressively. The measures announced by the government and the Reserve Bank of India (RBI) periodically to revitalize the sagging economy have also resonated well with investors.
• With selective relaxation in the lockdown and gradual opening up of economic activity in the country, foreign investors will be closely watching the developments on this front.
• A success on developing medicine and vaccines will lead to a V-shaped recovery in the economy and markets.

Voluntary Retention Route (VRR) scheme

• The VRR scheme is aimed at attracting long-term and stable FPI investments into debt markets.
• Investments through the route will be free of the regulatory norms applicable to FPI investments in debt markets, provided investors maintain a minimum share of their investments for a fixed period.
• VRR Scheme has a minimum retention period of three years and investors need to maintain a minimum of 75% of their investments in India.
• FPIs registered with Securities and Exchange Board of India (SEBI) are eligible to voluntarily invest through the route in government and corporate bonds.

V-Shaped Recovery

• A V-shaped recovery is characterized by a sharp economic decline followed by a quick and sustained recovery.
• The recession of 1953 is an example of a V-shaped recovery.
• A V-shaped recovery is different from an L-shaped recovery, in which the economy stays in a slump for a prolonged period of time.

RBI Cancels Licence of CKP Co-op Bank

Why in News

Recently, the Reserve Bank of India (RBI) has cancelled the licence of Mumbai-based CKP Co-operative Bank.

Key Points

• RBI has cancelled the licence of the bank as the financial position of the bank was highly adverse and unsustainable.
  
  • The bank is not in a position to pay its present and future depositors.
  • The bank failed to meet the regulatory requirement of maintaining a minimum capital adequacy ratio of 9% and reserves.
• RBI has asked the Registrar of Co-operative Societies, Maharashtra to start the process of winding up operations of CKP Co-operative bank and appoint a liquidator.
  
  • On liquidation, every depositor of the bank is entitled to get up to Rs 5 lakh from the Deposit Insurance and Credit Guarantee Corporation.
• In September last year, RBI had imposed restrictions on Punjab and Maharashtra Co-operative (PMC) Bank not to do any business for six months after it found major irregularities, which included financial irregularities, complete failure of internal control and systems, and wrongdoing and under-reporting of its lending exposure.

Capital Adequacy Ratio

• Capital Adequacy Ratio (CAR) is the ratio of a bank’s capital in relation to its risk weighted assets and current liabilities. It is also known as Capital-to-Risk Weighted Asset Ratio (CRAR).
• It is decided by central banks to prevent commercial banks from taking excess leverage and becoming insolvent in the process.
• The Basel III norms stipulated a capital to risk weighted assets of 8%.
• However, as per RBI norms, Indian scheduled commercial banks are required to maintain a CAR of 9%.

Deposit Insurance and Credit Guarantee Corporation

• DICGC came into existence in 1978 after the merger of Deposit Insurance Corporation (DIC) and Credit Guarantee Corporation of India Ltd. (CGCI) under the Deposit Insurance and Credit Guarantee Corporation Act, 1961.
  
  • It serves as a deposit insurance and credit guarantee for banks in India.
  • It is a fully owned subsidiary of and is governed by the Reserve Bank of India.
• DICGC charges 10 paise per ₹100 of deposits held by a bank. The premium paid by the insured banks to the Corporation is paid by the banks and is not to be passed on to depositors.
• DICGC last revised the deposit insurance cover to ₹5 lakh in Feb, 2020, raising it from ₹ 1 lakh since 1993. The protection cover of deposits in Indian banks through insurance is among the lowest in the world.
  
  • The Damodaran Committee on ‘Customer Services in Banks’ (2011) had recommended a five-time increase in the cap to ₹5 lakh due to rising income levels and increasing size of individual bank deposits.
• Banks, including regional rural banks, local area banks, foreign banks with branches in India, and cooperative banks, are mandated to take deposit insurance cover with the DICGC.

Combating Bioterrorism

Why in News

The Covid-19 pandemic has exposed the vulnerability of several world powers in the event of use of biological weapons against them by rogue states and terrorist groups.

• The United States, Britain and the Soviet Union were involved in developing complex biological weapons programs after World War II and several nations continue to do so currently as well.

Key Points

• Bioterrorism or Biological Attack:
  
  • It is the intentional release of viruses, bacteria, or other germs that can sicken or kill people, livestock or crops.
• Biological Weapons:
  
  • They use microorganisms and natural toxins to produce disease in humans, animals, or plants.
  • Biological weapons can be derived from: bacteria, viruses, rickettsia, biological toxins and fungi.
  • These agents can be deployed as biological weapons when paired with a delivery system, such as a missile or aerosol device.
  • Bacillus anthracis, the bacteria that causes anthrax, is one of the most likely agents to be used in a biological attack.
  • The most destructive bioterrorism scenario is the airborne dispersion of pathogens over a major population region.
  • Tropical agricultural pathogens or pests can be used as anticrop agents to hamper the food security worldwide.
• It is a substantial threat because small amounts of biotic agents can be effortlessly hidden, transported and discharged into vulnerable populations.
• It can impact and expose military and civilian susceptibilities to biological weapons and to the complexity of offering ample safeguards.
• Bioweapons experts believe that currently bioterrorists probably lack the biotechnological capability to produce-super pathogens or super pests.

Covid-19: Bioweapon or Not

• Novel-coronavirus is alleged to have originated in bats.
• Some intelligence agencies initially proclaimed that coronavirus occurred naturally but later on, they claimed that the pandemic might have begun from the Wuhan lab in China after the researchers were probably able to figure out how bat coronaviruses could mutate to attack humans.
• However, there is no proof that the pandemic virus was engineered or manipulated, yet.
• In the Indian context, with the existence of hostile neighbours like Pakistan and China, the threat of biological warfare becomes important and cannot be ruled out entirely.

Combating Bioterrorism

• The European Union (EU), Russia and China are finding ways to deter bioterrorism and biowarfare. The aim is to make it harder for terrorists to obtain the resources for designing biological weapons.
• These efforts should include:
  
  • Intelligence Sharing & Rapid Detection
    
    • Global intelligence agencies should operate together and share credible intelligence.
    • Combining human resources, laboratory resources and information supervision in novel, legal and satisfactory ways that allow for timely detection and categorization of hazards.
    • Rapid detection and surveillance are important for an efficient response to a bioterror strike.
  • Pathogen Analysis
    
    • Speedy, uniform techniques that allow for the discovery of an extensive range of pathogens used as biological weapons in a measurable fashion.
    • Pathogens are a usual part of the environment and can complicate detection attempts.
  • Strengthening the Biological and Toxin Weapons Convention
    
    • The Biological and Toxin Weapons Convention (BTWC) of 1972 prohibits signatory nations to develop, produce, stockpile or otherwise, acquire or retain:
      
      • Microbial or other biological agents or toxins whatever their origin or method of production, of types and in quantities that have no justification for prophylactic, protective or other peaceful purposes.
      • Weapons, equipment or means of delivery designed to use such agents or toxins for hostile purposes or in armed conflict.
    • However, there is no exact authentication method that can ensure compliance with the BTWC. Therefore, efforts must be made to strengthen the BTWC so that it helps to uncover and successfully prevent biological weapons programs.
    • India ratified and pledged to abide by its obligations in 2015.
  • Biodefense Systems
    
    • Upgrading and installing biodefense systems in major urban conglomerates to protect against deadly disease outbreaks initiated by bioterrorism.
      
      • During the Cold War, Soviet Union had set up several Biodefense systems across the country.
    • Developing and stockpiling vaccines and antimicrobial medicines that can be used to defend the people against infections triggered by biological weapons.
    • Coaching first responders on how to deal with a biological weapons attack.
    • Refining diagnostic laboratory capability and epidemiological capabilities.

Way Forward

• The studies conducted to assess the actual efficiency of counter bioterrorism measures are insufficient which needs to be changed.
• It becomes important that engaged and methodical efforts in studying the efficiency of counter bioterrorism measures are applied in a meticulous way.
• It should be taken into account that the implementation of some specific counter bioterrorism practices can possibly have consequences with respect to human rights, institutional liberties, fundamental democratic values and the Rule of Law.

MSP Hiked for Minor Forest Produce

Why in News

Recently, the Central government has revised the Minimum Support Price (MSP) for Minor Forest Produce (MFP).

• The MSP is the rate at which the government buys produce from farmers and tribals.
• The idea of MSP is to counter price volatility of commodities due to the factors like variation in their supply, lack of market integration and information asymmetry.

Key Points

• The increased Minimum support price (MSP) ranges from 16% to 66%.
• MSP for MFPs is revised once every three years by the Pricing Cell constituted under the Ministry of Tribal Affairs.
  
  • However, the authorities have revised the MSP much earlier than 3 years.
• This will offer much-needed support to tribal gatherers in view of the "exceptional and very difficult" circumstances prevailing in the country due to the Covid-19 pandemic.
• The Centre has also asked all the states to speed up procurement operations.
• The central government has also created an online monitoring dashboard, called the Van Dhan Monit Dashboard, for reporting the procurement activities undertaken at the state level.
  
  • The dashboard is a part of the “TRIFED E- Sampark Setu” that aims to facilitate exchange of information to and from every Panchayat and Van Dhan Kendra, either through email or mobile phone.
• States have appointed the Van Dhan Kendras as their primary procurement agents for MFP procurements from haat bazaars.

Van Dhan Vikas Kendra

• Van Dhan Vikas Kendras have been set up under the program ‘Van Dhan Yojana’ which was launched in 2018, in Chhattisgarh.
• The Van Dhan Vikas Kendra caters to ten Self Help Groups of thirty tribal gatherers each.
• The selection of the tribal beneficiaries and formation of the SHGs has been undertaken by the Tribal Cooperative Marketing Development Federation of India (TRIFED).
• The Van Dhan Vikas Kendras boost the economic development of tribals involved in the collection of Minor Forest Produce (MFP) and provide a sustainable MFP-based livelihood in MFP-rich districts.

Minor Forest Produce (MFP)

• MFP includes all non-timber forest produce of plant origin and includes bamboo, canes, fodder, leaves, gums, waxes, dyes, resins and many forms of food including nuts, wild fruits, honey, lac, tusser etc.
• It provides both subsistence and cash income for people who live in or near forests. They form a major portion of their food, fruits, medicines and other consumption items and also provide cash income through sales.

Opposition to Permanent Bru Settlement in Tripura

Why in News

In the middle of the Covid-19 lockdown, two community-specific groups have renewed their opposition to the permanent settlement of Bru refugees from Mizoram in Tripura.

• The two groups namely, Nagarik Suraksha Mancha (mostly representing Bengali people displaced from erstwhile East Pakistan post-partition in 1947) and the Mizo Convention have submitted a memorandum protesting against the proposed settlement of the displaced Brus in Tripura.

Background

• Bru or Reang is a community indigenous to Northeast India, living mostly in Tripura, Mizoram and Assam. In Tripura, they are recognised as a Particularly Vulnerable Tribal Group.
• In Mizoram, they have been targeted by groups that do not consider them indigenous to the state. In 1997, following ethnic clashes, nearly 37,000 Brus fled Mamit, Kolasib and Lunglei districts of Mizoram and were accommodated in relief camps in Tripura.
• Since then, 5,000 have returned to Mizoram in eight phases of repatriation, while 32,000 still live in six relief camps in North Tripura.
  
  • In June 2018, community leaders from the Bru camps signed an agreement with the Centre and the two state governments, providing for repatriation in Mizoram. But most camp residents rejected the terms of the agreement.
  • The camp residents say that the agreement doesn't guarantee their safety in Mizoram.
• The Centre, the governments of Mizoram and Tripura and leaders of Bru organisations signed a quadripartite agreement in January (2020) to let the remaining 35,000 refugees who have stayed back to be resettled in Tripura.
  
  • The rehabilitation package offered included financial assistance of ₹4 lakh and land for constructing a house for each family.

African Swine Fever in Assam

Why in News

The Centre has advised the Assam state government to go for culling of pigs affected by the African Swine Fever (ASF).

Key Points

• It has been advised to divide the affected areas into zones and go for culling accordingly.
• The disease was first reported in November-December, 2019 from the areas of China bordering Arunachal Pradesh.
• A few organised piggeries in Assam have been affected and the possible carrier could be humans.
  
  • However, there is no confirmation on humans being the carrier of the virus.
• Earlier in April, there were reported deaths of pigs due to the Classical Swine Fever (CSF).
• ASF and CSF are different from Swine Flu (H1N1) and do not affect humans.
• CSF can be prevented by proper vaccination but there is no vaccination for ASF. Culling of the affected pigs is the only option.

African Swine Fever

• It is a highly contagious and fatal animal disease that infects and leads to an acute form of hemorrhagic fever in domestic and wild pigs.
• It was first detected in Africa in the 1920s.
• The mortality is close to 100% and since the fever has no cure, the only way to stop its spread is by culling the animals.
• ASF is not a threat to human beings since it only spreads from animals to other animals.
• ASF is a disease listed in the World Organisation for Animal Health (OIE) Terrestrial Animal Health Code and thus, reported to the OIE.
