The dispute between Britain and Mauritius over Chagos islands


What to study?

For prelims: location of chagos islands, countries involved in the dispute.

For mains: what is the controversy all about, recent ICJ observations and the need of hour.


Why in News? The United Nation General Assembly (UNGA) has passed a non-binding resolution asking United Kingdom (UK) to return Chagos Archipelago in Indian Ocean to Mauritius.

What has the International Court of Justice said on this?

The UK should end its control of the Chagos Islands in the Indian Ocean as rapidly as possible. The islands are not lawfully separated from the former colony of Mauritius.


What’s the issue?

  • Mauritius claims it was forced to give up the islands – now a British overseas territory – in 1965 in exchange for independence, which it gained in 1968.


Arguments by Mauritius:

China continues to use ozone depleting CFC-11 in violation of Montreal Protocol


What to study?

For Prelims: Key facts on Montreal protocol.

For Mains: Significance of the Ozone layer and the need for protection.


Context: China has been illegally emitting Trichlorofluoromethane or CFC-11 — the banned ozone-depleting chemical — according to the research published in the journal Nature recently.


Key findings:

  • CFC-11 was phased out under the 1987 Montreal Protocol. Despite being the signatory to the Montreal Protocol, and agreeing to phase out production of CFC-11 in 2010, China continued to emit the polluting gas.
  • Emissions of CFC-11 were on the rise since 2013. In fact, the emissions increased by 25 per cent since 2012. Between 2008 and 2012, eastern China emitted an average of about 6,400 metric tonnes of CFC-11 per year. That number increased to about 13,400 metric tonnes per year from 2014 to 2017.


Reasons behind:

  • China has the world’s largest polyurethane foam market, accounting for about 40 per cent of the world’s consumption.
  • Chinese foam manufacturers have been using CFC-11 illegally to save on the higher cost of alternatives, such as hydrochloro-fluorocarbons like HCFC-141b, which is to be phased out in China by 2026.


Why limit the use of CFC- 11?

  • The hole in the ozone is on the path to recovery according to the World Meteorological Organization’s (WMO’s) assessment; and reduction in the atmospheric concentration of CFC-11 has made the second-largest contribution to the decline in the total atmospheric concentration of ozone-depleting chlorine since the 1990s. But this gas still contributes one-quarter of all chlorine reaching the stratosphere, and a timely recovery of the stratospheric ozone layer depends on a sustained decline in CFC-11 concentrations.
  • Continued success of the Montreal Protocol in protecting stratospheric ozone depends on continued compliance and China must adhere to it.


What you need to know about the Ozone layer?

The ozone layer absorbs most of the Sun’s ultraviolet light which is harmful to human life and other life forms. The layer absorbs about 97 to 99% of ultraviolet rays and maintain the ozone-oxygen cycle. Dobson unit is a unit which is used to measure the ozone in the atmosphere at a standard temperature and pressure.


Montreal protocol:

  • The Montreal Protocol includes a unique adjustment provision that enables the Parties to the Protocol to respond quickly to new scientific information and agree to accelerate the reductions required on chemicals already covered by the Protocol. These adjustments are then automatically applicable to all countries that ratified the Protocol.

WHO strategy on antivenoms


What to study?

For prelims and mains: snakebites- concerns, spread, WHO strategy-need and significance.


Context: The World Health Organization has unveiled a new strategy to dramatically cut deaths and injuries from snakebites, warning a dearth of antivenoms could soon spark a “public health emergency”.


Need for a comprehensive strategy:

  • Each year, nearly three million people are bitten by poisonous snakes, with an estimated 81,000-138,000 deaths. Another 400,000 survivors suffer permanent disabilities and other after-effects, according to WHO figures.
  • WHO has already categorised “snakebite envenoming” as a Neglected Tropical Disease.


WHO strategy:

  • Aim: to cut snakebite-related deaths and disabilities in half by 2030.
  • An important part of the strategy is to significantly boost production of quality antivenoms.
  • Reshape the market and employ greater regulatory control.
  • Restore a sustainable market for snakebite treatment. There is need for a 25-percent increase in the number of competent manufacturers by 2030.


Challenges producing antivenoms:

  • Poor data on the number and type of snake bites have led to difficulty in estimating needs, and deficient distribution policies have further contributed to manufacturers reducing or stopping production or increasing the prices of antivenoms.

Coral bleaching


What to study?

For prelims and mains: coral bleaching- causes, effects, concerns and measures to prevent.


Context: Researchers have found an alarming pattern of bleaching in the reefs in Mandapam, Keezhakkarai and Palk Bay in Gulf of Mannar regions.


Key findings:

  • Sea surface temperature ranged from 28.7°C to 31°C in the August 2018-February 2019 period and there was no bleaching seen then.
  • However, when the temperatures rose to between 32°C and 36°C between March 2019 and May 2019, researchers observed a pattern of bleaching in corals, which was different at different layers within the sea.


What are Coral reefs?

Coral reefs are important hotspots of biodiversity in the ocean. Corals are animals in the same class (Cnidaria) as jellyfish and anemones. They consist of individual polyps that get together and build reefs.



  • Coral reefs support a wide range of species and maintain the quality of the coastal biosphere.
  • Corals control the level of carbon dioxide in the water by converting it into a limestone shell. If this process does not take place, the amount of carbon dioxide in the ocean water would increase significantly and affect ecological niches.




  • Coral reefs are threatened by climate change.
  • When the sea surface temperature increases beyond a tolerable limit, they undergo a process of bleaching.


What is bleaching?

Basically bleaching is when the corals expel a certain algae known as zooxanthellae, which lives in the tissues of the coral in a symbiotic relationship. About 90% of the energy of the coral is provided by the zooxanthellae which are endowed with chlorophyll and other pigments. They are responsible for the yellow or reddish brown colours of the host coral. In addition the zooxanthellae can live as endosymbionts with jellyfish also.

When a coral bleaches, it does not die but comes pretty close to it. Some of the corals may survive the experience and recover once the sea surface temperature returns to normal levels.

Currency chest


What to study?

For Prelims: Currency chest- features.

For Mains: Need and significance.


Context: The Reserve Bank of India is planning to allow large modern currency chests to increase the service charges on cash deposited by non-chest bank branches from the existing rate of ₹5 per packet of 100 pieces to a higher rate subject to a maximum of ₹8 per packet. For this, only a currency chest (CC) that fulfils the minimum standards will be eligible to be classified as a large modern CC.


What are Currency chests?

Currency chests are branches of selected banks authorised by the RBI to stock rupee notes and coins.


Who determines the number of notes and coins to be printed?

The responsibility for managing the currency in circulation is vested in the RBI.

  1. The central bank advises the Centre on the number of notes to be printed, the currency denominations, security features and so on. The number of notes that need to be printed is determined using a statistical model that takes the pace of economic growth, rate of inflation and the replacement rate of soiled notes.
  2. The Government has, however, reserved the right to determine the amount of coins that have to be minted.


Role of currency chests:

  • The RBI offices in various cities receive the notes from note presses and coins from the mints. These are sent to the currency chests and small coin depots from where they are distributed to bank branches.
  • The RBI has set up over 4,075 currency chests all over the country. Besides these, there are around 3,746 bank branches that act as small coin depots to stock small coins.


Reserve Bank of India (RBI) recently issued new guidelines for banks to set up new currency chests. They include:

  • The new chests should have a processing capacity of 6.6 lakh pieces of banknotes per day. Those situated in the hilly/ inaccessible places, a capacity of 2.1 lakh pieces of banknotes per day.
  • The currency chests should have Chest Balance Limit (CBL) of Rs 1,000 crore, subject to ground realities and reasonable restrictions, at the discretion of the Reserve Bank.

Facts for Prelims:



What is it? It is a land-based ballistic missile of Pakistan.

  • Shaheen missile series is named after a Falcon (bird) species that lives in Pakistan’s mountains.
  • It is a land-based supersonic intermediate-range surface-to-surface guided ballistic missile.
  • It is capable of carrying all kinds of warheads i.e. both conventional (high explosive) as well as nuclear warheads.
  • It is capable of hitting targets up to 1,500-2000 kilometers. Thus is capable of reaching major cities in neighbouring India.


The white-throated rail.

Context: New research has found that the white-throated rail had once gone extinct, but rose from the dead thanks to a rare process called “iterative evolution”.

  • Iterative evolution means the repeated evolution of similar or parallel structures from the same ancestor but at different times.
  • The white-throated rail is the only flightless bird known in the Indian Ocean area. It is a chicken-sized bird, indigenous to Madagascar. Migrating to Aldabra, the rails evolved so that they lost the ability to fly.
