Current Affairs 18th May 2024 for UPSC Prelims Exam

UN – Global Growth

Context: The United Nations has raised its 2024 global economic growth forecast to 2.7%, up from its earlier prediction of 2.4% in January.

More In News

  • This improved outlook is driven by stronger performance in the U.S. and emerging markets like India.
  • While matching the 2023 growth rate, this figure remains below the pre-pandemic level of 3%.
  • The UN also anticipates further growth in 2025, projecting a rate of 2.8%.

Projections For India

  • India’s Growth: India’s GDP is expected to grow by 6.9% in 2024 and 6.6% in 2025.
    • The revision is primarily due to strong public investment and resilient private consumption, despite subdued external demand impacting merchandise export growth.
    • Pharmaceuticals and chemicals exports are expected to expand significantly.
  • Inflation: Consumer price inflation in India is projected to decrease from 5.6% in 2023 to 4.5% in 2024, remaining within the central bank’s target range.
  • Labour Market: Labour market indicators have improved due to robust growth and increased labour force participation.
  • Fiscal Deficit: The government remains committed to gradually reducing the fiscal deficit while increasing capital investment.
  • The IMF has raised India’s GDP growth to 6.8% and has termed the country as a bright spot amid the backdrop of a challenging global economy.
  • RBI estimates GDP growth at 7% for 2024-25, while the government has projected it in the 7-7.5% range.

South Asia’s Outlook

  • Regional Growth: South Asia’s GDP is projected to grow by 5.8% in 2024 and 5.7% in 2025, driven by India’s strong performance and a slight recovery in Pakistan and Sri Lanka.
  • Challenges: Tight financial conditions, fiscal and external imbalances, potential energy price increases, and geopolitical tensions pose risks to the region’s economic outlook.

Global Economic Outlook

  • Global Growth: The world economy is now forecast to grow by 2.7% in 2024 and 2.8% in 2025, mainly due to a better outlook in the U.S. and large emerging economies like Brazil, India, and Russia.
  • Trade Recovery: Global trade is expected to recover in 2024, with China’s foreign trade growing faster than expected in the first two months of 2024, driven by exports to emerging markets.
  • Challenges: Persistent geopolitical tensions, disruptions in the Red Sea, and escalating freight costs continue to pose challenges to global trade.

Other Notable Developments

  • China’s Growth: China’s growth is projected to moderate to 4.8% in 2024, facing challenges from the property sector.
  • Overall Outlook: While the global economic outlook has improved since January, challenges such as higher interest rates, debt sustainability, geopolitical tensions, and climate risks persist.


Context: Recently, two people were rescued after a group of orcas, also known as killer whales, sank their 15-metre-long sailing yacht in the Strait of Gibraltar, 22.5 kilometres off the coast of Morocco.

Previous Incidents

  • November 2023 Incident: Orcas attacked the rudder of a yacht for nearly 45 minutes, forcing the crew to abandon the boat, which eventually sank near the Tanger Med port, 45 km northeast of Tangier, Morocco.

Frequency of Interactions

  • Since 2020, over 700 interactions between orcas and boats have been recorded near the Strait of Gibraltar, with some boats sustaining significant damage.
  • The frequency of these interactions has made it a multinational issue involving scientists and officials from Spain, Portugal, and Morocco.

Possible Explanations for Orca Behavior

  • Playful Behaviour: Some scientists believe the orcas are simply playing or engaging in a fad behaviour, possibly initiated by a few individuals and then imitated by others.
  • Traumatic Experience: Another theory suggests that one or two orcas experienced a traumatic event, such as getting entangled in fishing lines, which triggered a change in their behaviour. This behaviour is then being copied by other orcas in the area.

Concerns and Future Implications

  • Researchers are worried that continued attacks on boats could endanger mariners and become a conservation issue for orcas.
  • While orcas are not typically aggressive towards humans in the wild, the increased interactions raise concerns about potential harm to both humans and the animals themselves.
About Orcas
  • Orcas, also known as killer whales, are found across the world.
  • They can grow up to 8 metres in length and weigh up to 6 tonnes as adults.
  • Family: They are the largest member of the Delphinidae family, which includes all dolphin species as well as other larger species like long-finned and short-finned pilot whales.
  • Social Structure: Orcas are highly social animals, typically living in pods, which are groups of maternally related individuals seen together more than half the time.
  • Communication and Navigation: Orcas rely on underwater sound for feeding, communication, and navigation.

Southern Resident Killer Whales

  • Endangered Status: Southern Resident killer whales are the only endangered population of killer whales in the United States.
  • Population Decline: Despite nearly two decades of federal legal protections, their population continues to decline and is critically endangered.
  • Current Population: There are only 73 Southern Resident Orcas left in the wild.
Strait Of Gibraltar
A narrow waterway separating Europe from Africa, connecting the Mediterranean Sea to the Atlantic Ocean.

  • Location: Narrowest point is between Morocco’s Point Cires and Spain’s Point Marroquí.

  • Depth: Depth ranges from 300 to 900 metres.
  • Geographical Significance: Forms a significant gap between the high plateau of Spain and the Atlas Mountains of Northern Africa.
  • Formation: Formed due to the northward movement of the African Plate towards the European Plate.
  • Water Flow: The Atlantic Ocean and the Mediterranean Sea have different salinity levels.
    • Highly saline Mediterranean waters flow outward and underneath the less saline Atlantic waters, which flow inward on top.
  • Shipping Route: Acts as a chokepoint for ships moving into or out of the Mediterranean Sea.
    • Vital shipping route for countries in northern Africa, southern Europe, and western Asia.
  • Important Port: The Moroccan port of Tanger-Med, near Tangier, is a significant port located on the Strait of Gibraltar.

Deda Method

  • Deda is a traditional method used for preserving seeds, making them look like boulders from a distance.
  • Seeds are preserved in leaves and packed almost airtight.
  • Packaged seeds are woven with Siali leaf (Bauhinia vahlii), locally known as ‘addakulu’, to create the deda.
  • Three-Layer Protection:
    • First Layer: Wood ash is spread inside the Siali leaves.
    • Second Layer: The ash is covered with lemon leaves to form a casing.
    • Third Layer: Seeds are preserved inside the casing and sealed.
  • Protection and Longevity:
    • This method protects seeds from pests and worms.
    • Stored seeds can be used for cultivation for up to five years.
  • Cultural Practice:
    • Widely practised by the Muria tribes in Chhattisgarh.
    • This method is a traditional practice handed down by ancestors in the forests of Chhattisgarh.
  • Tribal Settlements: The Murias have settled along the banks of the Godavari and Sabari rivers in the Godavari valley in Andhra Pradesh and Telangana.


  • A synchrotron is a type of circular particle accelerator where particles move in a loop.
  • Operation:
    • It accelerates charged particles (typically electrons) through sequences of magnets until they reach nearly the speed of light.
    • These high-speed electrons produce very bright light known as synchrotron light.
  • Synchrotron Light:
    • This intense light, mainly in the X-ray region, is millions of times brighter than conventional light sources and 10 billion times brighter than sunlight.
    • The light is directed down beamlines to experimental workstations for research purposes.
  • Research Applications:
    • Scientists use synchrotron light to study minute matter such as atoms and molecules.
    • They analyse how samples scatter, diffract, absorb, or re-emit the light to uncover details about their structure or chemical composition.
  • Global Presence:
    • There are approximately 70 synchrotrons worldwide, each varying in use and capability, with some focusing on applied sciences and others on fundamental research.
