  • What is a Serological Survey?

    A Serological Survey was recently conducted in New Delhi to determine the exposure of the novel coronavirus among the population.

    Try this question from CSP 2019:

    Which one of the following statements is not correct?

    (a) Hepatitis B virus is transmitted much like HIV.
    (b) Hepatitis B, unlike Hepatitis C, does not have a vaccine.
    (c) Globally, the number of people infected with Hepatitis B and C viruses is several times more than those infected with HIV.
    (d) Some of those infected with Hepatitis Band C viruses do not show the symptoms for many years.

    Serological Survey

    • A serological survey seeks to assess the prevalence of the disease in a population by detecting the presence of specific antibodies against the virus.
    • A serological test is performed to diagnose infections and autoimmune illnesses. It can also be conducted to check if a person has developed immunity to certain diseases.
    • The survey included the IgG Enzyme-Linked Immunosorbent Assay (ELISA) test which estimates the proportion of the population exposed to SARS-CoV-2 infection.
    • The IgG test is not useful for detecting acute infections, but it indicates episodes of infections that may have occurred in the past.
    • The test has been approved by ICMR for its high sensitivity and specificity.

    Highlights of the Survey

    • The study found the presence of antibodies in 22.86 percent of the people surveyed.
    • It indicated that a large number of infected persons remain asymptomatic.

    Why needed such survey?

    • Since it is not possible to test everyone in the population, serological studies are used as a tool to make an estimate of the extent of disease spread in the community.

    Conclusions from the survey

    • Results show that a significant proportion of the population is still vulnerable to contracting the novel coronavirus infection.
    • Containment measures need to continue with the same rigour.
    • Non-pharmacological interventions such as physical distancing, use of face mask/cover, hand hygiene, cough etiquette and avoidance of crowded places etc. must be followed strictly.

  • [pib] DDT and its impact on environment

    India has supplied 20.60 MT of DDT to South Africa for its Malaria control program.

    Try this question from CSP 2014:

    With reference to ‘Global Environment Facility’, which of the following statements is/are correct?
    (a) It serves as financial mechanism for ‘Convention on Biological Diversity’ and ‘United Nations Framework Convention on Climate Change’
    (b) It undertakes scientific research on environmental issues at global level
    (c) It is an agency under OECD to facilitate the transfer of technology and funds to underdeveloped countries with specific aim to protect their environment.
    (d) Both (a) and (b)

    What is DDT?

    • Dichloro-diphenyl-trichloroethane commonly known as DDT is a colorless, tasteless, and almost odorless crystalline chemical compound.
    • It was developed as the first of the modern synthetic insecticides in the 1940s.
    • It was initially used with great effect to combat malaria, typhus, and other insect-borne human diseases among both military and civilian populations.

    Why is it controversial?

    • DDT is a persistent organic pollutant that is readily adsorbed to soils and sediments, which can act both as sinks and as long-term sources of exposure affecting organisms.
    • Routes of loss and degradation include runoff, volatilization, photolysis and aerobic and anaerobic biodegradation.
    • Due to hydrophobic properties, in aquatic ecosystems DDT is absorbed by aquatic organisms and thus bio-accumulates in the food web.

    Threats of DDT

    • The bioaccumulation of DDT has caused eggshell thinning and population declines in multiple North American and European bird of prey species.
    • DDT is an endocrine disruptor. It is considered likely to be a human carcinogen.

    In use despite ban

    • A worldwide ban on agricultural use of DDT was formalized under the Stockholm Convention on Persistent Organic Pollutants.
    • But its limited and still-controversial use in disease vector control continues, because of its effectiveness in reducing malarial infections, balanced by environmental and other health concerns.

    Back2Basics: Stockholm Convention on POPs

    • Stockholm Convention is an international environmental treaty, signed in 2001 and effective from May 2004 that aims to eliminate or restrict the production and use of persistent organic pollutants (POPs).
    • In 1995, the United Nations Environment Programme (UNEP) called for global action to be taken on POPs.
    • POPs are defined by the UNEP as chemical substances that persist in the environment, bio-accumulate through the food web, and pose a risk of causing adverse effects to human health and the environment.

    Bioaccumulation and Biomagnification

    • Bioaccumulation and biomagnification are two different processes that often occur in tandem with one another.
    • Bioaccumulation is the process by which toxins enter the food web by building up in individual organisms.
    • Biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web.

  • BlackRock Android Malware

    Various security firms have alerted about new malware, called BlackRock.

    Try this question from CSP 2018:

    Q.The terms ‘WannaCry, Petya, Eternal Blue’ sometimes mentioned news recently are related to

    (a) Exoplanets

    (b) Cryptocurrency

    (c) Cyberattacks

    (d) Mini satellites

    BlackRock

    • BlackRock isn’t exactly a new malware. In fact, it is based on the leaked source code of the Xeres malware, itself derived from a malware called LokiBot.
    • The only big difference between BlackRock and other Android banking trojans is that it can target more apps than previous malwares.

    How does it work?

    • BlackRock works like most Android malware. Once installed on a phone, it monitors the targeted app.
    • When the user enters the login and/or credit card details, the malware sends the information to a server.
    • BlackRock uses the phone’s Accessibility feature and then uses an Android DPC (device policy controller) to provide access to other permissions.
    • It can be used to send and steal SMS messages, hide notifications, keylogging, AV detection, and much more.

    Threats posed

    • The new malware can steal information like passwords and credit card information from about 377 smartphone applications, including Amazon, Facebook, and Gmail.
    • It is so powerful that it makes antivirus applications useless.

    Godhan Nyay Yojana

    • Under the scheme, the Chhattisgarh government will purchase cow dung at the rate of Rs 2 per kg.
    • This scheme will turn cow dung into a profitable commodity.
    • The scheme also aims to make cow rearing economically profitable and to prevent open grazing in the state, as well as help with the problem of stray animals on roads and in urban areas.

    How will the scheme help the rural economy?

    • The scheme will generate additional income and increase employment opportunities.
    • The government will procure cow dung and prepare vermicompost in order to move towards organic farming.
    • There is a huge market for organic farming. Vermicompost will be sold by cooperative societies.
    • Distribution of vermicompost fertilizer to farmers will be done as a commodity loan by cooperative societies, banks.

    Preventing strays in urban areas

    • In urban areas, the scheme will prevent movement of stray animals on roads and highways, and also improve urban sanitation with proper disposal of waste produced by cattle.
    • Cattle will be tagged with the owner’s name, address, mobile number to the neck of each animal after the survey to ensure accountability of cattle owners if their cattle are found in the open.

  • Vitamin D and its health benefits

    There have been considerable discussions in scientific circles on the importance of vitamin D in these days of the COVID-19 pandemic.

    Try this question from CSP 2017:

    Q.Regular intake of fresh fruits and vegetables is recommended in the diet since they are a good source of antioxidants. How do antioxidants help a person maintain health and promote longevity?

    (a) They activate the enzymes necessary for vitamin synthesis in the body and help prevent vitamin deficiency.

    (b) They prevent excessive oxidation of carbohydrates, fats and proteins in the body and help avoid unnecessary wastage of energy.

    (c) They neutralize the free radicals produced in the body during metabolism.

    (d) They activate certain genes in the cells of the body and help delay the ageing process.

    Vitamin D and its prevalence

    • It is produced when sunlight (or artificial light, particularly in the ultraviolet region of 190-400 nm wavelength) falls on the skin.
    • Light triggers a chemical reaction to a cholesterol-based molecule and converts it into calcidiol in the liver and into calcitriol in the kidney.
    • It is these two molecules that are physiologically active.
    • Since sunlight is important for the generation of vitamin D, tropical countries have an advantage over the northern countries.
    • India, being a tropical country, one would expect naturally derived vitamin D levels to be good.

    Why Vitamin D is important?

    • Vitamin D deficiency can affect COVID-19 high-risk patients, particularly those who are diabetic, have heart conditions, pneumonia, obesity and those who smoke.
    • It is also associated with infections in the respiratory tract and lung injury.
    • Besides, vitamin D is known to help in having the right amount of calcium in the bones, catalyse the process of protecting cell membranes from damage, preventing the inflammation of tissues.
    • Moreover, it helps stop tissues from forming fibres and weakening bones from becoming brittle, leading to osteoporosis.

  • Voting right to migrant workers

    A large number of migrant workers cannot vote in their constituency. This assumes significance when we consider that the Supreme Court has interpreted the right to vote as an extension of the fundamental right of the freedom of expression. So,  the ECI should find ways to enable them exercise their right.

    Universal adult franchise: India’s achievement

    • India moved from a restrictive 15 per cent of Indians having limited voting rights to universal adult franchise.
    • Transformative nature of the Indian national movement and the ideals of equality and non-discrimination enshrined in it played a crucial role in it.
    • It was B R Ambedkar’s clarity of vision that resulted in Article 326 of the Constitution.
    • Ambedkar had influenced public opinion on the matter for decades, giving evidence before the Southborough committee.

    Migrant workers: some facts

    • According to the 2011 Census, the number of internal migrants stands at 45 crore.
    • Among these, 26 per cent of the migration, that is, 11.7 crore occurs inter-district within the same state.
    • 12 per cent of the migration, that is, 5.4 crore occurs inter-state.
    • Both official and independent experts admit that this number is underestimated.
    • Circular migration accounts for those migrants who have not permanently relocated to host cities, and instead circulate between host and home cities.
    • Short-term and circular migration could itself amount to 6-6.5 crore.
    • Half of these are inter-state migrants.
    • Migrant labourers mostly hail from most poverty-driven rural areas.
    • They are from among the most marginalised sections SC/STs and OBCs, and other minorities.
    • As of 2011, Uttar Pradesh and Bihar were the largest sources of inter-state migrants, with 83 lakh and 63 lakh migrants respectively.

    Low turnout in the source states

    •  Economic constraints disable a majority of migrant workers from voting as they cannot commute to their home states on the polling day.
    • One survey shows that only 48 per cent of those surveyed voted in the 2009 Lok Sabha elections, when the national average was 59.7 per cent.
    • In the 2019 Lok Sabha polls, major sender states such as Bihar and UP had among the lowest voter turnout rates.

    Inability to satisfy “Ordinary Resident” criteria

    • Given the nature of migration being circular and seasonal, migrants are not permanent/long-term residents in host cities.
    • So, they do not satisfy the requirements of being an “ordinary resident” under Section 20 of the Representation of People Act (RP Act), in the host state, to obtain voter cards.
    • They are, therefore, unable to transfer their constituency.

    Solution: Postal ballot

    • The Election Commission of India has under Section 60(c) of the RP Act the power to notify a certain class of persons to vote via postal ballot.
    • The ECI’s much-proclaimed mission to ensure “no voters are left behind” has resulted in attempts to ensure a secure system of postal ballots.
    • In the 2019 Lok Sabha elections, more than 28 lakh votes were received via postal ballots.
    • The Indian migrant worker should be given the right to vote through a similar system.

    Consider the question “There is scope for increasing the voter turnout in India and enabling the migrant workers to vote could be one of them. Examine the reasons for low voting turnout in India and suggest the measures to improve it.”

    Conclusion

    Securing the migrant workers right to vote will make democracy inclusive, responsible and sensitive to the concerns of those who find it difficult to make their voice heard.

  • Debate around ‘One-Nation- One-Curriculum’

    The Supreme Court has refused to entertain a plea for a uniform and common curriculum for school students between aged six and 14 across the country rather than have diverse ones such as the CBSE, the ICSE and State Board.

    Practice question for mains:

    Q.Discuss the efficacy of the One-Nation- One-Board System and its limitations.

    Background

    • Schools in India are mainly columned primarily into 4 boards of education, namely CBSE, ICSE and IB (International Baccalaureate).
    • In total, there are 41 boards of education throughout India.
    • These different boards of education have different syllabuses, which creates a knowledge gap among school students.
    • To curate this gap, syllabuses of every board for the Indian schools are being brought at par.

    What was the plea before the Supreme Court?

    • The petition asked considering the setting up of a National Education Council/Commission and following a “one-nation-one-board” system in which the ICSE is merged with the CBSE.
    • It urged a standard textbook with chapters on fundamental rights, duties, directive principles and the golden goals set out in the Preamble.
    • It asked to make the study compulsory for all the children aged 6-14 years throughout the territory of India.

    Why did the court refuse?

    • Uniform curriculum was a “matter of policy” and the judiciary could not “command” the government said the Supreme Court bench.

    Pros of common curriculum

    • The Article 21A of the Constitution has the RTE (Right to Education) Act says that every child in the age of 4 to 16 should be given free and compulsory education.
    • To keep a check on that, a common syllabus throughout the country is required. This will help all the students to be on par with education.
    • With a common syllabus throughout the country, no student will lag behind in education and hence, this will help them prepare better for competitive examinations or admission tests beyond school level for the outside world.
    • Politics, in some cases, influence the education system which is very unfair for the students. Some state boards prefer the admission of students from their own region and willingly keep the seats of colleges and universities occupied for students passing their 12th standard from their state boards.
    • A common syllabus would also mean that there would be no discrimination regarding quality education on the basis of caste, creed, social, religious beliefs or economic backgrounds.
    • It will provide an unbiased ground of learning and development of the young ones, which may turn out to be very beneficial in future.
    • At present, some of the state boards are not updating their syllabus frequently as per the changes in society. This loophole will be eliminated with the introduction of the uniform syllabus in India.

    Limitations

    • Students may miss learning things specific to their region and their culture. This can be a threat to diversity.
    • Current school students might get affected or stressed out on a sudden change of syllabus.
    • An abrupt change in the syllabus may hamper the stability of a student with the academics which will not be a good turn.
    • A new set of the syllabus will bring in more workload on teachers and parents too.

    Conclusion

    • Uniform education system having common syllabus and common curriculum would achieve the code of a common culture, removal of disparity and depletion of discriminatory values in human relations.
    • It would enhance virtues and improve the quality of life, elevate the thoughts, which advance the constitutional philosophy of equal society.
    • Though the government has been trying to put up with equality in education, the barriers have been inevitable to date.
    • A common syllabus seems to be a wise option, but it is yet to be implemented over the entire country.

  • [pib] Bhagirathi Eco-Sensitive Zone (ESZ)

    The Environment Ministry has approved the Zonal Master Plan (ZMP) for the Bhagirathi Eco-Sensitive Zone.

    Note the following things with respect to the ESZs:

    1) Its demarcation

    2) Law/Regulation providing it

    3) Boundary restrictions

    Bhagirathi ESZ

    It covers a watershed of about  100 kilometres stretch of the river  Bhagirathi from Gaumukh to Uttarakashi covering an area of  4179.59 square km.

    What are the Eco-sensitive Zones (ESZs)?

    • Eco-Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
    • The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
    • They also act as a transition zone from areas of high protection to areas involving lesser protection.

    How are they demarcated?

    • The Environment (Protection) Act, 1986 does not mention the word “Eco-Sensitive Zones”.
    • However, Section 3(2)(v) of the Act, says that Central Government can restrict areas in which any industries, operations or processes or class of industries, operations or processes shall be carried out or shall not, subject to certain safeguards.
    • Besides Rule 5(1) of the Environment (Protection) Rules, 1986 states that central government can prohibit or restrict the location of industries and carrying on certain operations or processes on the basis of certain considerations.
    • The same criteria have been used by the government to declare No Development Zones (NDZs).

    Defining its boundaries

    • An ESZ could go up to 10 kilometres around a protected area as provided in the Wildlife Conservation Strategy, 2002.
    • Moreover, in the case where sensitive corridors, connectivity and ecologically important patches, crucial for landscape linkage, are beyond 10 km width, these should be included in the ESZs.
    • Further, even in the context of a particular Protected Area, the distribution of an area of ESZ and the extent of regulation may not be uniform all around and it could be of variable width and extent.
