  • In an unprecedented and rare move, the Geneva-based Office of the High  Commissioner for Human Rights (OHCHR) has announced that it plans to file an application in the Supreme Court, asking to be impleaded in petitions challenging the Citizenship (Amendment) Act (CAA).
  • And the Ministry of External Affairs (MEA) said the United Nations body had no right to file a petition that will ask the court to appoint the Commissioner for Human Rights as an assistant or ‘amicus curiae’ in the case.


U.N. rights body to move Supreme Court on Citizenship Amendment Act OHCHR CAA
  • The High Commissioner [Michelle Bachelet] intends to submit an ‘amicus curiae’ brief shortly on the Citizenship [Amendment] Act [CAA] in the Indian Supreme Court, in accordance with the Court’s established procedures.
  • The amicus curiae will focus on providing an overview of relevant and applicable international human rights standards and norms to support the Court’s deliberations in the context of its review of the CAA
  • The OHCHR plan has been criticised by diplomatic and legal experts as an “overreach” by it.

Implications for India

  • The Citizenship Amendment Act is an internal matter of India and concerns the sovereign right of the Indian Parliament to make laws.
  • NO foreign party has any locus standi on issues pertaining to India’s sovereignty.
  • The CAA has to be tested on the touchstone of the Indian Constitution and not U.N. Convention.
  • If such interventions as ‘amicus curiae’ are allowed, it might set a wrong precedent
  • The U.N. rights body’s move as “absolutely unprecedented in the diplomatic history of India”.


  • The Citizenship (Amendment) Act (CAA), 2019 seeks to amend the Citizenship Act, 1955.
  • The Citizenship Act,1955 provides various ways in which citizenship may be acquired. It provides for citizenship by birth, descent, registration, naturalisation and by incorporation of the territory into India.
  • The CAA Bill was enacted on December 12, 2019 after it was cleared by Parliament.
  • It promises to fast-track citizenship for undocumented migrants belonging to six faiths not including Islam and Judaism, who fled from religious persecution in Bangladesh, Afghanistan and Pakistan before December 21, 2014.

Office of the High Commissioner for Human Rights (OHCHR)

  • The Office of the United Nations High Commissioner for Human Rights, is commonly known as the Office of the High Commissioner for Human Rights (OHCHR) or the UN Human Rights Office.
  • OHCHR is a department of the Secretariat of the United Nations that works to promote and protect the human rights that are guaranteed under international law and stipulated in the Universal Declaration of Human Rights of 1948.
  • The office was established by the UN General Assembly on 20 December 1993 in the wake of the 1993 World Conference on Human Rights.
  • The office is headed by the High Commissioner for Human Rights, who co-ordinates human rights activities throughout the UN System and acts as the secretariat of the Human Rights Council in Geneva, Switzerland.

The objectives of OHCHR are to:

  1. Promote universal enjoyment of all human rights by giving practical effect to the will and resolve of the world community as expressed by the United Nations
  2. Play the leading role on human rights issues and emphasize the importance of human rights at the international and national levels
  3. Promote international cooperation for human rights
  4. Stimulate and coordinate action for human rights throughout the United Nations system
  5. Promote universal ratification and implementation of international standards
  6. Assist in the development of new norms
  7. Support human rights organs and treaty monitoring bodies
  8. Respond to serious violations of human rights
  9. Undertake preventive human rights action

  • The Central government is working on the establishment of an exclusive body, called the National Interlinking of Rivers Authority (NIRA), to implement projects for linking rivers.
  • NIRA is expected to take up both inter-State and intra-State projects.
  • It will also make arrangements for generating up funds, internally and externally.
  • The subject of establishment of the Authority, NIRA, was discussed at the meeting of the Special Committee on Inter-Linking of Rivers (ILR) in February 2020.

ILR in India

  • The Indian Rivers Inter-link is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking Indian rivers by a network of reservoirs and canals to enhance irrigation and groundwater recharge, reduce persistent floods in some parts and water shortages in other parts of India.
  • The Inter-link project has been split into three parts:
    1. Northern Himalayan rivers inter-link component
    2. Southern Peninsular component and starting 2005
    3. Intrastate rivers linking component.
  • The project is being managed by India’s National Water Development Agency (NWDA), under its Ministry of Water Resources.


  • The National Water Development Agency (NWDA), a Registered Society under the Ministry of Water Resources, was set up in the year 1982.
  • It was established to carry out the water balance and other studies on a scientific and realistic basis for optimum utilisation of Water Resources of the Peninsular rivers system.
  • It was also tasked to prepare feasibility reports and give concrete shape to Peninsular Rivers Development Component of National Perspective.
  • In 1990, it was also entrusted with the task of Himalayan Rivers Development Component of National Perspectives. Recently, the functions of NWDA have been further modified and the work of preparation of detailed Project Reports (DPR) of various link proposals and Pre-feasibility Reports.
  • It has been also entrusted to prepare feasibility reports of intra-State links as proposed by the States.

ILR Projects in Consideration

As of now, six ILR projects have been under examination of the authorities.—

  1. Ken-Betwa,
  2. Damanganga- Pinjal,
  3. Par-Tapi-Narmada,
  4. Manas-Sankosh-Teesta-Ganga,
  5. Mahanadi-Godavari and
  6. Godavari-Cauvery (Grand Anicut)

With regard to the peninsular rivers, the Centre has chosen to focus on the Godavari-Cauvery link.

Benefits of the Interlinking of River Projects

India receives most of its rain during monsoon season from June to September

Most of it falls in northern and eastern part of India. The amount of rainfall in southern and western part are comparatively low, and hence, these places which will have shortage of water.

  • Therefore, Interlinking of rivers will help these areas to have water throughout the year.
  • It will reduce the dependence of farmers on monsoon rains.
  • Revenues for the States will increase with increasing production of Crops.
  • The economic impact of the failure of a single monsoon is very substantial, hence a reduction in the dependency on monsoons rains will reduce the debilitating economic impact.
  • It will ease the water shortages in Western and Southern India.
  • It will help mitigating the impacts of recurrent floods in Eastern India.
  • Water from the basins that are affected by floods almost every year (Ganga, Brahmaputra) can be diverted to other areas where there is scarcity of water; this can be achieved by linking the rivers.
  • Thus – There are Advantages in Both – Controlling Floods and Reducing Scarcity of Water.
  • The river interlinking project claims to generate total power of 34,000 MW (34 GW) and India needs clean energy to fuel its development processes. Hence the ILR Projects can help with India’s Energy needs.
  • Socio-economic life of people will improve as the water needs get fulfilled.
  • Inter-state water disputes can also be handled after implementation of ILR Projects.
  • Transportation through navigation will Increase Income Sources and increase connectivity.
  • Fishing in rural areas can also be improved as a result of ILR Projects.

Arguments Against ILP Projects

  • Concerned scholars questioned the merits of inter-link projects citing lack of holistic assessment of social-ecological impacts like water-logging, salinisation and the resulting desertification.
  • The concerns about sediment management, especially on the Himalayan system loom large. When the idea is to transfer water from the ‘surplus’ Himalayan river systems to ‘deficit’ basins of the southern part of India, the differential sediment regime defining the flow regimes need to be plugged into the equation. This will entail changes in ecosystem structures in both parts.
  • Damming India’s east-coast rivers to take their water westwards will curtail downstream flooding and thereby, the supply of sediment—a natural nutrient—destroying fragile coastal ecosystems and causing coastal and delta erosion
  • The spirit of federalism is ignored in the river interlinking project. There is dissent on the part of the state governments (Kerala).

Way Forward

  • Local solutions (like better irrigation practice) and watershed management, should be focused on.
  • The government should alternatively consider the National Waterways Project (NWP) which “eliminates” friction between states over the sharing of river waters since it uses only the excess flood water that goes into the sea unutilized
  • The necessity and feasibility of river-interlinking should be seen on case to case basis, with adequate emphasis on easing out federal issues.

Black carbon concentrations near the Gangotri glacier rose 400 times in summer due to forest fires and stubble burning from agricultural waste, and triggered glacial melt, says a study by scientists at the Wadia Institute of Himalayan Geology (WIHG).


  • The team of scientists from WIHG- measured variations of black carbon concentration at Chirbasa, near the Gangotri glacier in the Indian Himalaya, and located at an altitude of 3,600 metres, during the year 2016.
  • The monthly mean concentration of EBC (equivalent black carbon) was found to be minimum in August 2020 and maximum in the month of May 2020.
  • The observed seasonal mean concentrations of EBC indicated a pristine glacial source and an absence of EBC sources in the locality

What is Black Carbon?

  • Black carbon is a potent climate-warming component of particulate matter formed by the incomplete combustion of fossil fuels, wood and other fuels.
  • Complete combustion would turn all carbon in the fuel into carbon dioxide (CO2), but combustion is never complete and CO2, carbon monoxide, volatile organic compounds, and organic carbon and black carbon particles are all formed in the process.
  • The complex mixture of particulate matter resulting from incomplete combustion is often referred to as soot.

Adverse Effects of Black Carbon

  • Black carbon is a short-lived climate pollutant with a lifetime of only days to weeks after release in the atmosphere.
  • During this short period of time, black carbon can have significant direct and indirect impacts on the climate, glacial regions, agriculture and human health.
  • Several studies have demonstrated that measures to prevent black carbon emissions can reduce near-term warming of the climate, increase crop yields and prevent premature deaths.
  • Black carbon absorbs solar energy and warms the atmosphere.
  • When it falls to earth with precipitation, it darkens the surface of snow and ice, reducing their albedo (the reflecting power of a surface), warming the snow, and hastening melting.

India and Black Carbon Emission

  • India is the second largest emitter of black carbon in the world, with emissions expected to increase dramatically in the coming decades.
  • Indo Gangetic plains are found to be the largest contributor.

Brown Carbon:

  • Brown carbon is a carbonaceous aerosol which absorbs solar radiation over a broad range of wavelengths which is beginning to be seen as an important contributor to global warming.
  • Brown Carbon absorbs both inorganic and organic pollutants, leading to serious effects on human health. Hence, Brown carbon (light-absorbing organic carbon) has attracted interest as a possible cause of climate change.
  • Brown Carbon is a class of organic carbon, known for its light brownish colour, absorbs strongly in the ultraviolet wavelengths and less significantly going into the visible.
  • Types of brown carbon include tar materials from smouldering fires or coal combustion, breakdown products from biomass burning, a mixture of organic compounds emitted from soil, and volatile organic compounds given off by vegetation.
Brown Carbon Black Carbon
Brown Carbon is brown in colour and its absorption is limited to UV and lower visible wavelengths. Aerosol absorption depends on the mass, mixing state, chemical composition and the refractive index of the species present in the atmosphere. The ratio of Black Carbon to organic mass determines the colour of the particles which is in turn influenced by the burning conditions. Black carbon is dark in color and shows strong light absorbing capacity throughout the spectra.

Two weeks after a high-power committee (HPC), chaired by Prime Minister Narendra Modi, selected the new Chief Vigilance Commissioner (CVC) and the Chief Information Commissioner (CIC), the Centre is yet to officially notify the appointments.

Department of Personnel and Training (DoPT) — the nodal Ministry that handles government postings.


  • Central Vigilance Commission (CVC) is an apex Indian governmental body created in 1964 to address governmental corruption.
  • In 2003, the Parliament enacted a law conferring statutory status on the CVC.
  • It has the status of an autonomous body, free of control from any executive authority, charged with monitoring all vigilance activity under the Central Government of India, advising various authorities in central Government organizations in planning, executing, reviewing and reforming their vigilance work.
  • The CVC was set up by the Government in February, 1964 on the recommendations of the Committee on Prevention of Corruption, headed by Shri K. Santhanam- The parliament enacted the CVC Act 2003 and set up the CVC.
  • Hence, the CVC is a Statutory Body.

Functions of CVC

  • The CVC receives complaints on corruption or misuse of office and to recommend appropriate action. Following institutions, bodies, or a person can approach to CVC:
    • Central government
    • Lokpal
    • Whistle blowers
  • It is not an investigating agency. The CVC either gets the investigation done through the CBI or through chief vigilance officers (CVO) in government offices.
  • It is empowered to inquire into offences alleged to have been committed under the Prevention of Corruption Act, 1988 by certain categories of public servants.
  • Its annual report gives the details of the work done by the commission and points to systemic failures which lead to corruption in government departments. Improvements and preventive measures are also suggested in the report.


  • The Central Information Commission has been constituted with effect from 12-10-2005 under the Right to Information Act, 2005.
  • Hence, CIC is a Statutory Body.
  • The jurisdiction of the Commission extends over all Central Public Authorities.
  • It was constituted to act upon complaints from those individuals who have not been able to submit information requests to a Central Public Information Officer or State Public Information Officer due to either the officer not have been appointed, or because the respective Central Assistant Public Information Officer or State Assistant Public Information Officer refused to receive the application for information under the Right to Information Act.

Functions of CIC

  1. Order enquiry into any matter on reasonable grounds only.
  2. Secure compliance of its decisions from any public authority.
  3. Receive and inquire into a complaint from any person:
    • Who has not received any response to his request for information within a specified time
    • Who deems the information given to him/her incomplete, false or misleading, and any other matter related to securing the information
    • Who has been unable to submit a request for information due to the non-appointment of an officer
    • Who considers the fees so charged unreasonable
    • Who was refused the information requested
  4. The commission has the power to examine any record under the control of the public authority. All such records have to be given to the Commission during examination and nothing shall be withheld.
  5. During inquiries, the CIC has the powers of a civil court, such as the powers to:
    • Summon and enforce the attendance of persons, and compel them to give oral or written evidence on oath and produce documents or things
    • Require the discovery and inspection of documents
    • Receive evidence on affidavit
    • Requisition public records or copies from any office or court
    • Issue summons for the examination of documents or witnesses
    • Any other matter that may be prescribed
  6. The CIC also submits an annual report to the GOI on the implementations of the provisions of the Act. This report is then placed before both the Houses of Parliament.

Effects of COVID-19 on Export and Import

  • Slowdown in economic activity in China is likely to weigh on exports from India. China’s economic growth is likely to moderate to below 6% in 2020.
  • Export of commodities like ores (India exports 72% of its total ores to China), organic chemicals, cotton, etc. is likely to get hit should the disruption from the COVID-19 continue for an extended period

How is Value of Rupee Determined?

  • The value of a currency, just like any other commodity, is determined by supply and demand. The supply of a currency and its demand in the market.
  • No single institution or organization determines the exchange rate of rupee at present, not even the RBI.
  • Rather, the exchange rate of rupee with foreign currencies is determined by a combination of market factors.
  • By playing a direct hand in the supply and demand process RBI can maintain the fixed exchange rate.

Some of the Factors that determine Currency Exchange Rates are:

  • International Parity Conditions
  • Balance of Payments
  • Economic Policies of a government (Fiscal Policy, Budget, Investment policy and Foreign Trade Policies) and a country’s central Bank (Cost of money, interest rates, monetary policy)
  • General macroeconomic conditions of the country
  • Inflation levels and trends
  • Balance of Trade
  • Market Psychology & perception
  • General political stability

How was exchange rate of Rupee determined before 1990s?

  • Prior to the period of economic liberalization in the 1990s, India followed a fixed exchange rate system.
  • The Indian rupee was pegged to the US dollar and a basket of other currencies. In pegging, the value of a currency is fixed in a predetermined ratio to another more stable and internationally used currency or to a bunch of such currencies.
  • Fixed exchange rate does not mean the value of the currency will not change. It means that the value of the currency will move in tandem with the currency or currencies to which it is pegged i.e., the ratio of the value of the currencies will be maintained.
  • The exchange rate will not change every day but it may be reset on particular dates known as revaluation dates.
  • In this economic system, the government or the RBI is the authority which ensured the exchange rate of the rupee is fixed with respect to other currencies.

The swamp wallaby is likely the only mammal pregnant and lactating all life long, researchers have said.

How is it possible? 

  • Female wallabies and kangaroos have two uteri and two separate ovaries.
    At the end of a pregnancy in one uterus, a new embryo develops in the other uterus.
  • Kangaroos and wallabies regularly have an embryo in the uterus, a young joey in the pouch, and a third semi-dependent young at foot, still drinking its mother’s milk.
  • In kangaroos, the new embryo is conceived a day or two after the previous birth.
  • In the swamp wallaby (Wallabia bicolor), the new conception happens one or two days before the previous birth.
swamp wallaby, swamp wallaby pregnant, swamp wallaby kangaroo, swamp wallaby australia, swamp wallaby news

What happens after birth?

  • As soon as the mature foetus is born and settles in the pouch, the swamp wallaby arrests the development of the new embryo.
  • This is called embryonic diapause, which happens in many animals to pause reproduction until the conditions are right — season, climate, food availability.
  • For wallabies, this is also to ensure that the new one is born only when the pouch is free again.
  • If this did not happen, the swamp wallaby would be birthing new young every 30 days — it has a short gestation period — and its pouch could not support that.

The hare parallel: 

  • There is only one other mammal, the European brown hare (Lepus europaeus), that conceives additional embryos before giving birth.
  • There are, however, two key differences. In the hare, the new embryos are conceived in the same uterus that is already supporting foetuses in late stages — which, the researchers note, may be all the more remarkable.
  • The other difference is that only the swamp wallaby is pregnant all its life.
  • “The hare is only pregnant with the possibility of conceiving new embryos during distinct breeding seasons over about 5-6 months of the year. The rest of the time it is not pregnant or lactating at all.

About Swamp Wallaby:

  • The swamp wallaby is a small macropod marsupial of eastern Australia.
  • It inhabits thick undergrowth in forests and woodlands, or shelter during the day in thick grass or ferns, emerging at night to feed.
