Carbon Dating

Open in new window


  • Prelims – Current Affairs

In news: A Varanasi district court has issued notice regarding carbon-dating of the disputed structure known to have been found inside the premises of the Gyanvapi mosque.

What is Carbon Dating?

  • Carbon dating, also called radiocarbon dating is method of age determination that depends upon the decay to nitrogen of radiocarbon (Carbon-14).
  • This method was developed by the American physicist Willard F. Libby about 1946.
  • Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere.
  • The neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.

How it works?

  • Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.
  • Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
  • Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.

The half-life concepts:

  • Carbon-14 has a half-life of 5,730 ± 40 years—i.e., half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years.
  • Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

Its uses:

  • It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
  • The method is widely used by geologists, anthropologists, archaeologists, and investigators in related fields.

The Kyrgyzstan-Tajikistan conflict

Open in new window


Prelims – Current Affairs (Maps)

Context: Nearly 100 people have been killed and scores injured in violent border clashes between Kyrgyzstan and Tajikistan.

  • The borders of the two republics were demarcated under Joseph Stalin’s leadership.
  • Historically, the Kyrgyz and Tajik populations enjoyed common rights over natural resources.
  • Ferghana valley continues to be a site of struggle and frequent violent outbursts, with the location consisting primarily of Tajiks, Kyrgyz, and Uzbeks, who have historically shared common sociological specificities, economic activities, and religious practices.
  • This ‘development project’ resulted in the large-scale displacement of nomadic communities, eventually contributing to the ‘environment driver’ of the current conflict.

BrahMos Missiles

Open in new window


  • Prelims – Science and Technology

Context: The Defence Ministry signed a ₹1,700-crore contract with BrahMos Aerospace Pvt Ltd for 35 combat and three practice BrahMos supersonic surface-to-surface cruise missiles for two P-15B class of stealth guided missile destroyers of the Indian Navy.

About Brahmos:

  • BrahMos is a joint venture between the DRDO and Russia’s NPO Mashinostroyeniya and the missile derives its name from Brahmaputra and Moskva rivers.
  • On June 12, 2001, the BrahMos supersonic cruise missile was first tested from a land-based launcher in Chandipur.
  • In the 21 years since, BrahMos has been upgraded several times, with versions tested on land, air, and sea platforms.

Background and development:

  • Since the early 1980s, the Integrated Guided Missile Development Programme, conceived and led by Dr A P J Abdul Kalam, started developing a range of missiles including Prithvi, Agni, Trishul, Akash and Nag.
  • An Inter-Governmental Agreement was signed with Russia in Moscow in 1998
    • This led to the formation of BrahMos Aerospace, a joint venture between DRDO and NPO Mashinostroyenia (NPOM), the Indian side holding 50.5% and the Russians 49.5%.
  • In 1999, work on development of missiles began in labs of DRDO and NPOM after BrahMos Aerospace received funds from the two governments.
    • The first successful test in 2001 was conducted from a specially designed land-based launcher.

Strategic significance:

  • BrahMos is a two-stage missile with a solid propellant booster engine.
  • Its first stage brings the missile to supersonic speed and then gets separated.
  • The liquid ramjet or the second stage then takes the missile closer to three times the speed of sound in cruise phase.
  • The missile has a very low radar signature, making it stealthy, and can achieve a variety of trajectories.
  • The ‘fire and forget’ type missile can achieve a cruising altitude of 15 km and a terminal altitude as low as 10 m to hit the target.
  • Cruise missiles such as BrahMos, called “standoff range weapons”, are fired from a range far enough to allow the attacker to evade defensive counter-fire.
  • The BrahMos has three times the speed, 2.5 times flight range and higher range compared to subsonic cruise missiles.

Versions deployed in all three-Armed forces are still being tested regularly:


  • The land-based BrahMos complex has four to six mobile autonomous launchers, each with three missiles on board that can be fired almost simultaneously.
  • Batteries of the land-based systems have been deployed along India’s land borders in various theatres.
  • The upgraded land attack version, with capability of cruising at 2.8 Mach, can hit targets at a range up to 400 km with precision.
  • Advanced versions of higher range and speed up to 5 Mach are said to be under development.
  • The ground systems of BrahMos are described as ‘tidy’ as they have very few components.


  • The Navy began inducting BrahMos on its frontline warships from 2005.
  • These have the capability to hit sea-based targets beyond the radar horizon.
  • The Naval version has been successful in sea-to-sea and sea-to-land modes.
  • The BrahMos can be launched as a single unit or in a salvo of up to eight missiles, separated by 2.5-second intervals.
  • These can target a group of frigates with modern missile defence systems.


  • On November 22, 2017, BrahMos was successfully flight-tested for the first time from a Sukhoi-30MKI against a sea-based target in the Bay of Bengal.
  • BrahMos-equipped Sukhoi-30s, which have a range of 1,500 km at a stretch without mid-air refuelling, are considered key strategic deterrence for adversaries both along land borders and in the strategically important Indian Ocean Region.


  • This version can be launched from around 50 m below the water surface.
  • The canister-stored missile is launched vertically from the pressure hull of the submarine, and uses different settings for underwater and out-of-the-water flights.
  • This version was successfully tested first in March 2013 from a submerged platform off the coast of Visakhapatnam.

Rupee Depreciation

Open in new window


  • Prelims – Indian Economy, Interest rate, IMF etc
  • Mains – GS 3 (Fiscal policy, Monetary policy, Impact of free fall of the rupee)

Context: There has been a consistent deterioration of Indian Rupee’s (INR) exchange rate with respect to the US Dollar ($) over the last few month. It breached the psychologically significant exchange rate level. The fall in Rupee has been going on since the war in Ukraine began, and crude oil prices started going up.

What is Depreciation?

  • Currency depreciation is a fall in the value of a currency in a floating exchange rate system.
  • For example: USD 1 used to equal to Rs. 70, now USD 1 is equal to Rs. 77, implying that the rupee has depreciated relative to the dollar i.e., it takes more rupees to purchase a dollar.

Impact of Depreciation of Indian Rupee: Depreciation in rupee is a double-edged sword for the Reserve Bank of India.


  • Weaker rupee should theoretically give a boost to India’s exports, but in an environment of uncertainty and weak global demand, a fall in the external value of rupee may not translate into higher exports.


  • It poses risk of imported inflation, and may make it difficult for the central bank to maintain interest rates at a record low for longer.
  • India meets more than two-thirds of its domestic oil requirements through imports.
  • India is also one of the top importers of edible oils. A weaker currency will further

What determines the rupee’s value?

  • The value of any currency is determined by demand for the currency as well as its supply.
  • When the supply of a currency increases, its value drops.
  • In the wider economy, central banks determine the supply of currencies, while the demand for currencies depends on the amount of goods and services produced in the economy.
  • In the forex market, the supply of rupee is determined by the demand for imports and various foreign assets. So, if there is high demand to import oil, it can lead to an increase in the supply of rupees in the forex market and cause the rupee’s value to drop.
  • The demand for rupees in the forex market, on the other hand, depends on foreign demand for Indian exports and other domestic assets.
  • When there is great enthusiasm among foreign investors to invest in India, it can lead to an increase in the supply of dollars in the forex market which in turn causes the rupee’s value to rise against the dollar.

What is causing the rupee to lose value against the dollar?

  • Since March this year, the U.S. Federal Reserve has been raising its benchmark interest rate causing investors seeking higher returns to pull capital away from emerging markets such as India and back into the U.S.
  • This, in turn, has put pressure on emerging market currencies which have depreciated significantly against the U.S. dollar so far this year.
  • Even developed market currencies such as the euro and the yen have depreciated against the dollar and the dollar index is up more than 9% so far this year.
  • Some analysts believe that the RBI’s surprise decision to raise rates in May could have simply been to defend the rupee by preventing any rapid outflow of capital from India.
  • India’s current account deficit, which measures the gap between the value of imports and exports of goods and services, is expected to hit a 10 year high of 3.3% of gross domestic product in the current financial year.
  • Foreign investors are unlikely to plough capital into India when investment yields are rising in the U.S.

What lies ahead?

  • It is neither wise nor possible for the RBI to prevent the Rupee from falling indefinitely. Defending the Rupee will result in India exhausting its forex reserves over time because global investors have much bigger financial clout.
    • Most analysts believe that the better strategy is to let the Rupee depreciate and act as a natural shock absorber to the adverse terms of trade. Thus, RBI should focus on containing inflation which is its legal mandate.
  • The Government should contain its borrowings. Higher borrowings (fiscal deficit) by the Government consume domestic savings. Hence, the Industrial and other sectors of economy are forced to borrow from abroad.
  • Over the long run, the Rupee is likely to continue to depreciate against the Dollar given the significant differences in long-run inflation between India and the U.S.
  • The U.S. Federal Reserve has raised rates to tackle historically high inflation in the US that hit a 41-year high of 8.6%.
    • This will induce other countries and emerging markets in particular to raise their own interest rates to avoid disruptive capital outflows and to protect their currencies.
  • As interest rates rise across the globe, the threat of a global recession also rises as economies readjust to tighter monetary conditions.


  • Analysts believe that, over the long run, the rupee is likely to continue to depreciate against the dollar given the significant differences in long run inflation between India and the U.S.
  • The exchange rate has fallen to its historical low of 80, however Indian Rupee has shown a better performance in comparison to currencies of emerging economies.
  • The inflation divides between the U.S and India will continue to further depreciate the Rupee. Nonetheless, with proactive fiscal and monetary measures, India can stabilize its currency value.

Adani’s global footprint and India’s infrastructure diplomacy

Open in new window


  • Prelims – Current Affairs
  • Mains – GS 3 (Economy- Infrastructure)


From mines to ports and logistics, the Adani conglomerate has been expanding across sectors, regions. This has gone hand in hand with India’s diplomatic and strategic outreach towards infrastructure diplomacy.

What is infrastructure diplomacy?

  • Infrastructure diplomacy is to promote infrastructure cooperation and economic ties overseas through political means and to enhance political trust between countries via collaboration in infrastructure development.


  • Foreign presence much earlier: In fact, the Adani group had been scouting abroad much earlier. Since 2010, the Adani group has been in Australia, developing the Carmichael coal mine in Queensland.
  • A greenfield multi-purpose port: In 2017, Adani Ports and Special Economic Zones (Ltd) signed an MoU for a greenfield multi-purpose port for handling containers at Carey Island in Selangor state, about 50 km southwest of Kuala Lumpur.

What is the situation now?

  • Company pursues international infrastructure projects aggressively: The last two years, however, have seen the company pursue international infrastructure projects aggressively. In May 2022, APSEZ made a winning bid of $1.18 billion for Israeli state-owned Haifa Port, jointly with Israeli chemicals and logistics firm Gadot.
  • Strategic joint investments: In August this year, APSEZ and Abu Dhabi’s AD Ports Group signed MoU for “strategic joint investments” in Tanzania. The new ASEZ-AD MoU will look at a bouquet of infrastructure projects besides Bagamoyo in the East African Indian Ocean nation — rail, maritime services, digital services, and industrial zones.
  • India’s strategic objectives than has been possible so far: Is it just a coincidence that Adani’s global expansion closely shadows the Chinese footprint along its Belt and Road Initiative? Or is it that as Delhi competes with China for influence in the neighbourhood and beyond, the Adani group’s size, resources and capacity are seen as a key element in achieving India’s strategic objectives than has been possible so far.
  • India’s infrastructure diplomacy: Is now becoming identified the world over with one company.
  • Public and Private investment to bridge gaps: For the Adani group, described as India’s biggest ports and logistics company, there couldn’t be a better time.
    • As the Quad grouping of Australia, India, Japan, and the US, competes with China in the Indo-Pacific, it has committed “to catalyse infrastructure delivery” by putting more than $50 billion on the table for “assistance and investment” in the Indo-Pacific over the next five years and “drive public and private investment to bridge gaps”.

Implications of infrastructure diplomacy:

  • Win-Win deal:
    • Adani’s new “no-hands” model of doing business with neighbours a power plant in Jharkhand, exporting all its output to Bangladesh has been seen as a “win-win” deal.
  • Economic interests lie at the heart of geopolitics:
    • The link between diplomacy and commercial interests has generated its share of debate, especially in the US, where its diplomats, intelligence agencies and military interventions abroad have actively pushed the interests of big business first the hunt for cheaper raw materials, then for markets abroad, then to shift industry where manpower was cheaper.
    • As seen in the new age trading blocs the US-led IPEF, and the Chinese dominated RCEP economic interests lie at the heart of geopolitics.


At a time when global rivalries are growing sharper in the shadow of the war in Europe, and as India looks out for its own interests, pushing powerful corporates to the centre-stage of its diplomacy, whether it is to build ports, buy or sell weapons or make chips, is inevitable.
