  • Gujarat Anti-Conversion Law

    The Gujarat High Court this week stayed key provisions of The Gujarat Freedom of Religion (Amendment) Act, 2021 pertaining to marriages involving religious conversion of either of the two parties.

    What is the Anti-Conversion Law?

    • The legislation has amended the 2003 Gujarat Freedom of Religion Act.
    • The amendment was brought in line with several similar laws enacted last year by right-wing-ruled states, starting with Uttar Pradesh.
    • The laws seek to end conversion through unlawful means, specifically prohibit any conversion for marriage, even if it is with the consent of the individual except when a prior sanction is obtained from the state.
    • Apart from UP and Gujarat, Madhya Pradesh and Himachal Pradesh too, have also enacted similar laws.

    Controversial provisions

    • Vagueness: It gives powers to the state to conduct a police inquiry to verify the intentions of the parties to convert for the purposes of marriage.
    • Burden of proof: Section 6A reverses the burden of proof on the partner of the converted spouse to prove that he/she did not coerce the other spouse.
    • Intent of marriage: Section 4 allows the aggrieved person, their parents, brother, sister, or any other person related by blood or marriage or adoption to file an FIR challenging the conversion and subsequent marriage.
    • Conversion as Allurement: The law considers lawful conversions as “allurement” in vague.
    • Discrimination: It defines over-broad terms; prescribes different jail terms based on gender; and legitimizes the intrusion of family and the society at large to oppose inter-faith marriages.

    Issues with such laws

    • Stereotyping of lawful conversion: The new anti-conversion laws shift the burden of proof of a lawful religious conversion from the converted to his/her partner.
    • Curb on individual freedom: Legal experts have pointed out that the laws interfere in an individual’s agency to marry a partner from different faith and to choose to convert from one’s religion for that purpose.
    • Interference of state: Apart from being vague and sweeping, the laws also test the limits to which the state can interfere in the personal affairs of individuals.
    • Violative of FRs: The freedom to propagate one’s religion (A25) and the right to choose a partner are fundamental rights (A21) that the new anti-conversion laws impinge upon.

    What has the Gujarat High Court held?

    • A Division Bench of the Gujarat High Court has granted an interim stay on certain provisions of the amendment that interfere with inter-faith marriages.
    • It has held that the bill interferes with the intricacies of marriage including the right to the choice of an individual, thereby infringing Article 21.
    • The interim stay on certain provisions will have to be confirmed when the larger challenge is decided.

    What was the government’s defence?

    • The state government had argued that the law did not prohibit all inter-faith marriages, but only the ones based on fraud and coercion.
    • To buttress its submission, Advocate General had argued that the Act must be read as a whole to interpret the provision, and the provision alone could not be read by itself.
    • However, the court said that the wider interpretation would happen at a later stage, and stayed the provisions for the time being. A larger challenge would determine the fate of the law eventually.

    Significance of the ruling

    • The HC ruling, although preliminary, comes as a relief to interfaith couples from being harassed.
    • The reading could have a bearing on challenges pending in other HCs (namely in MP, UP, Himachal etc).
    • However, its real impact on the ground could be limited, as larger constitutional nuances are often difficult to permeate, especially when it is not a final and binding verdict.

This is causing health problems to the villagers downstream who depend on the river for their water needs. She is perturbed and mentions her concern to her colleagues who have been with the company for longer periods. They advise her to keep quite as anyone who mentions the topic is summarily dismissed. She cannot risk losing her job as she is the sole bread-winner for her family and has to support her ailing parents and siblings. At first, she thinks that if her seniors are keeping quiet, why should she stick out her neck. But her conscience pricks her to do something to save the river and the people who depend upon it. At heart she feels that the advice of silence given by her friends is not correct though she cannot give reasons for it. She thinks you are a wise person and seeks your advice. (a) What arguments can you advance to show her that keeping quiet is not morally right? (b) What course of action would you advice her to adopt and why? (20 Marks)

    Important Rebellion

  • Melting of the Greenland’s Snow Cover

    Recently the summit of Greenland received rain and not snow. This has sparked fear as scientists are pointing to it as evidence that Greenland is warming rapidly.

    About Greenland

    • Greenland is the world’s largest island located between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago.
    • It is an autonomous territory within the Kingdom of Denmark.
    • Though physiographically a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers).
    • The majority of its residents are Inuit, whose ancestors migrated from Alaska through Northern Canada, gradually settling across the island by the 13th century.
    • It has three-quarters of its surface covered with a permanent ice sheet, which is increasingly coming under threat because of climate change.

    Rain at Greenland: The rarest phenomenon

    • At the highest point on Greenland’s ice sheet, the US maintains a Summit Station, a research facility that observes changes occurring over the island as well as in Arctic weather.
    • Researchers observed rain at the normally frigid summit, with the precipitation extending up to Greenland’s southeast coast.
    • The rain, coupled with warm conditions, caused a major melting event at the summit.
    • This led to rapid ice melting running off into the ocean in volumes, thus accelerating global sea-level rise.

    A cause of worry

    • Greenland, which is two-thirds the size of India, already witnessed one of its most severe melting events.
    • It has lost 8.5 billion tons of surface mass in one day– the third such extreme event in the past decade.
    • The UN’s “code red” climate report released last week concluded that the burning of fossil fuels led to Greenland melting in the last 20 years.
    • The rapid melting is also threatening polar bears, which now have to make their way hundreds of kilometers towards Greenland’s interior from the coasts, where they usually find enough food.

    Question 4)  

    Q.4 You have recently been posted as a District Development Officer in a traditionally rural area that has seen rapid economic development in the past few years. You notice that there is a huge disparity between the number of male and female children in the area. When you go to the hospital and check the birth registry, you realise that registered new-born babies are mostly males. On further investigation, you notice a similar pattern in the village primary school, which has more male students than females. When you raise the issue with your colleagues, they ignore it and carry on with their work. You suspect that the practice of female foeticide may be entrenched in the area as you had read about the issue in the context of this state while studying for the Civil Services Examination. It seems to you that respected members of the community like doctors, politicians and government officials have chosen to ignore the issue, given the prevalence of patriarchy and mind-set of voters in the area. Thus, despite rapid economic development, preference for male child continues to persist. Based on the information above, answer the following: (a) Do you have any ethical duty in this scenario? Justify your views. (b) What would be your next steps and why? (20 Marks)

  • Is a caste census desirable?

    With the 2021 Census coming up, several political parties have demanded a nationwide caste census.

    What is Caste Census?

    • Every Census in independent India from 1951 to 2011 has published data on Scheduled Castes and Scheduled Tribes, but not on other castes.
    • Before that, every Census until 1931 had data on caste.
    • However, in 1941, caste-based data was collected but not published.
    • In the absence of such a census, there is no proper estimate for the population of OBCs, various groups within the OBCs, and others.
    • The Mandal Commission estimated the OBC population at 52%, some other estimates have been based on National Sample Survey data.
    • Some political parties make their own estimates in states and Lok Sabha and Assembly seats during elections.

    Arguments for caste census

    A caste census is not merely geared to the reservation issue.

    • Enumerating the marginalized: A caste census would actually bring to the particular the number of people who are at the margins, or who are deprived, or the kind of occupations they pursue, or the kind of hold that institutions like caste have on them.
    • Data for Policymaking: This information is absolutely necessary for any democratic policymaking.
    • Judicial backing: The courts in India have often emphatically said that it is important to have adequate data with regard to the reservation.
    • Caste offers privilege: Caste is not only a source of disadvantage; it is also a very important source of privilege and advantage in our society.
    • Caste doesn’t marginalize: We need to do away with the idea of caste being applicable to only disadvantaged people, poor people, people who are somehow lacking.
    • Rids away caste rigidities: Counting of caste doesn’t necessarily perpetuate caste or the caste system. Myths of caste elitisms can be debunked through a caste census.

    Arguments against caste census

    • 50% breach: It is argued that a Socio-Economic Caste Census is the only way to make a case to breach the 50% cap on reservation and rationalize the reservation matrix in the country.
    • Rising assertiveness: More the State ignores out caste, the more is the tendency to preserve caste, protect it. This has been observed in many states.
    • Chaos: Data gathering itself is a big problem because it can become very, very invasive. But we need to actually balance it with enabling people and asserting citizen equality.
    • Social friction: Caste identification can lead to friction amongst various classes.

    Breaching the 50% cap

    • Judicial Substantiation: The 50% cap, as introduced by the court, has not really been argued through.
    • Questioning the sacrosanctity: Some feel that nothing sacrosanct about the 50% limit − it can be exceeded, if necessary, but a clear argument should be given for why this is being done.

    Inefficacy of reservations

    • Fractional benefits: The way reservation is practiced has invariably led to elites among castes and communities.
    • Domination: These elites within the castes have tended to exercise their dominance over their very communities and not let them exercise the kind of freedoms, or search for equality, which any democratic polity deserves.
    • Welfare isn’t reservation: The state has helped privileged communities far more, even though this help has not taken the explicit form of programs like reservation.

    Why is a caste census always controversial?

    • Data manipulation: This is a manifestation of the principle that those in power control data and information.
    • Censoring of data: We have had instances where this data has been collected but has not been made public.
    • Relative deprivation: Since a caste census is a necessity, it is not a happy thing, it is not a great achievement, it is just something that the State has to do circumstantially.
    • Vote bank politics: Vested interests of particular state governments in hunt for vote banks are also visible these days.

    SECC has the solution

    • We have got locked into a mindset where we think only those communities which want welfare benefits from the state must be enumerated.
    • Many have argued that a Socio-Economic Caste Census would be the best way to rationalize reservation based on data and make a strong case for breaching this gap.
    • Earlier governments argued that counting caste will perpetuate it.

    Conclusion

    • Favoring one caste becomes a disfavor for others. This is an undeniable fact of Indian society.
    • It seems that the caste census will happen unless something extraordinary happens in our polity.
    • There are also important questions of demands coming up because of mismatches between the numbers that we come out with and the share in resources that different communities have.
    • This is a kind of nightmare that all governments fear. So, they would much rather leave things vague.
    • The Backward Classes are more than 50% of the population. And this dispensation knows that it cannot afford to lose the support of the Backward Classes.

  • India ratifies Kigali Amendment to the Montreal Protocol

    The Union Cabinet has given its approval for ratification of the Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer for phase down of Hydrofluorocarbons (HFCs) by India.

    What is Montreal Protocol?

    • The Montreal Protocol on Substances that Deplete the Ozone Layer is an international agreement made in 1987.
    • It was designed to stop the production and import of ozone-depleting substances and reduce their concentration in the atmosphere to help protect the earth’s ozone layer.
    • It sits under the Vienna Convention for the Protection of the Ozone Layer.

    Objectives

    • The convention was adopted in 1985 and has highlighted the adverse effect of human activity on ozone levels in the stratosphere and the discovery of the ‘ozone hole’.
    • Its objectives are to promote cooperation on the adverse effects of human activities on the ozone layer.
    • It has since undergone nine revisions, in 1990 (London), 1991 (Nairobi), 1992 (Copenhagen), 1993 (Bangkok), 1995 (Vienna), 1997 (Montreal), 1998 (Australia), 1999 (Beijing) and 2016 (Kigali).

    India and the Protocol

    • India became a Party to the Protocol on 19 June 1992 and since then has ratified the amendments.

    What is the Kigali Amendment?

    • It is an international agreement to gradually reduce the consumption and production of hydrofluorocarbons (HFCs).
    • It is a legally binding agreement designed to create rights and obligations in international law.
    • While HFCs do not deplete the stratospheric ozone layer, they have high global warming potential ranging from 12 to 14,000, which has an adverse impact on climate.

    What are the Ozone Depleting Substances?

    Ozone-depleting substances are chemicals that destroy the earth’s protective ozone layer. They include:

    • chlorofluorocarbons (CFCs)
    • halons
    • carbon tetrachloride (CCl4)
    • methyl chloroform (CH3CCl3)
    • hydro Bromo fluorocarbons (HBFCs)
    • hydrochlorofluorocarbons (HCFCs)
    • methyl bromide (CH3Br)
    • bromochloromethane (CH2BrCl)

    Where are they used?

    The main uses of ozone-depleting substances include:

    • CFCs and HCFCs in refrigerators and air conditioners,
    • HCFCs and halons in fire extinguishers,
    • CFCs and HCFCs in foam,
    • CFCs and HCFCs as aerosol propellants, and
    • Methyl bromide for fumigation of soil, structures and goods to be imported or exported.

    Now answer this PYQ:

    Q.Consider the following statements:

    Chlorofluorocarbons, known as ozone-depleting substances are used:

    1. In the production of plastic foams
    2. In the production of tubeless tyres
    3. In cleaning certain electronic components
    4. As pressurizing agents in aerosol cans

    (a) 1, 2 and 3 only

    (b) 4 only

    (c) 1, 3 and 4 only

    (d) 1, 2, 3 and 4

    [wpdiscuz-feedback id=”1wrtcabaix” question=”Please leave a feedback on this” opened=”1″]Post your answers here.[/wpdiscuz-feedback]

    Why phase them out?

    Implementation strategy and targets:

    • India will complete its phase-down of HFCs in 4 steps from 2032 onwards with a cumulative reduction of 10% in 2032, 20% in 2037, 30% in 2042, and 80% in 2047.

    Major Impact

    • HFCs phasedown is expected to prevent the emission of up to 105 million tonnes of carbon dioxide equivalent of GHGs, helping to avoid up to 0.5 degrees Celsius of global temperature rise by 2100, while continuing to protect the ozone layer.
    • It will achieve energy efficiency gains^ and carbon dioxide emissions reduction – a “climate co-benefit,”
    • HFCs phrase-down implementation will involve synergies to maximize the economic arid social co-benefits, besides environmental gains.
    • There would be scope for domestic manufacturing of equipment as well as alternative non-HFC and low-global warming potential chemicals to enable the industry to transition to the low global warming potential alternatives as per the agreed HFC phase-down schedule.
    • In addition, there would be opportunities to promote domestic innovation for new generation alternative refrigerants and related technologies.

    Colorado River

    • The Colorado River flows from the Rocky Mountains into the southwestern US and into Mexico.
    • The river is fed by snowmelt from the Rocky and Wasatch mountains and flows a distance of over 2,250 km (river Ganga flows through a distance of roughly 2,500 km) across seven states and into Mexico.
    • The Colorado River Basin is divided into the Upper (Wyoming, Colorado, New Mexico, Utah and northern Arizona) and Lower Basins (parts of Nevada, Arizona, California, southwestern Utah and western New Mexico).
    • In the Lower Basin, the Hoover Dam controls floods and regulates water delivery and storage.
    • Apart from the Hoover dam, there is the Davis Dam, Parker Dam and the Imperial Dam that regulate the release of water from the Hoover Dam.

    Major lakes in its basin

    • Lake Mead is the largest reservoir in the US in terms of volume and was formed in the 1930s by the Hoover Dam in Southern Nevada.
    • Its main source of water is obtained from the Rocky Mountain snowmelt and runoff.
    • The other is Lake Powell, the reservoir created by the Glen Canyon Dam in Arizona.

    Reasons for shortage

    • Since the year 2000, this river basin has been experiencing a prolonged drought.
    • This persistent drought has led to a lowering down of the water levels in the basin’s reservoirs to meet the demand over the years.
    • But even with great water storing capacity, over the years the demand for water from the basin has increased whereas supply is restricted.
