Global Hunger Index (GHI) 2023

India ranks 111 out of a total of 125 countries in the Global Hunger Index 2023.

  • Released by – Concern Worldwide and Welthungerhilfe.

Global Hunger Index (GHI)

GHI is a tool for comprehensively measuring and tracking hunger at global, regional, and national levels.




  • Share of the population with insufficient caloric intake.

Child stunting

  • Share of children under age five who have low height for their age.
  • It reflects chronic undernutrition.

Child wasting

  • Share of children under age 5 who have low weight for their height.
  • It reflects acute undernutrition.

Child mortality

  • Share of children who die before their 5th birthday.
  • It reflects inadequate nutrition and unhealthy environments.
  • Based on the values of 4 indicators, a GHI score is calculated on a 100-point scale reflecting the severity of hunger.
  • Zero “0” is the best possible score (no hunger) and “100” is the worst.
  • Global Scenario – Global hunger remains too high, and progress on reducing hunger has largely stalled.
  • This stagnation relative to 2015 largely reflects the combined effects of overlapping crises
    • COVID-19 pandemic
    • Russia-Ukraine war
    • Economic stagnation
    • Impacts of climate change,
    • Conflicts among many countries
  • India’s Performance - With a score of 28.7, India’s hunger level is serious.
  • India has the highest child wasting rate in the world, at 18.7%, reflecting acute undernutrition



Issues in methodology

  • GHI does not reflect India’s true position.
  • According to Poshan Tracker % of child wasting has been below 7.2%, as compared to the value of 18.7% of GHI 2023.
  • 3 out of the 4 indicators are related to the health of children and cannot be representative of the entire population.
  • The 4th indicator ‘Proportion of Undernourished (PoU) population’ is based on an opinion poll conducted on a very small sample size.

'Poshan Tracker' ICT Application was developed and deployed by Ministry of Women and Child Development to dynamically determine stunting, wasting, underweight, and obesity status based on a child's height, weight, gender, and age.

Dragonfly Festival, 2023

The 6th edition of the Dragonfly Festival is being conducted across 11 States in India.

  • The festival has been running for the past 5 years and celebrates Dragonfly and Damselfly’s role in keeping our environment healthy.

The tag for this year’s festival is Dragonflies in Focus: Inspire Wetland Champions’.

  • Organised by - WWF India
  • Partnership - Bombay Natural History Society, India Biodiversity Portal, Indian Dragonfly Society and other partners.
  • Aim - To create awareness for the conservation of these insects.
  • Activities - Documenting the dragonflies and damselflies by observing different patterns like mating, resting, flying or feeding.


  • It is an order of flying insects that includes the dragonflies and damselflies.

Ozone Hole over Antarctica

European Space Agency Copernicus Sentinel-5P satellite measurements over Antarctica have detected a giant hole in the ozone layer which was roughly 3 times the size of Brazil.

  • This is one of the biggest ozone holes observed so far and this year’s ozone hole started earlier than usual, and had a big extension.
  • Ozone Hole - It is not technically a “hole” where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic.
  • Timing – At the beginning of Southern Hemisphere spring (August–October).
  • Ozone hole over Antarctica – Its size fluctuates every year, opening in August and closing again in November or December.
  • Opening of hole – In the long months of polar darkness over Antarctica in the winter, atmospheric conditions are unusual.
  • An endlessly circling whirlpool of stratospheric winds called the polar vortex isolates the air in the center.
  • Because it is completely dark, the air in the vortex gets so cold that clouds form and enables chemical reactions to take place.
  • This converts the inactive Cl reservoir chemicals into active chlorine gas (Cl2) in atmosphere.
  • In spring, the UV light from sunlight rapidly breaks Cl gas into free Cl in the stratosphere which destroys ozone.

A free chlorine atom in atmosphere participate in a series of chemical reactions called as catalytic reaction and thus a single chlorine atom to destroy thousands of ozone molecules.

  • Closing of hole – When temperatures warm and the polar vortex weakens, it ends the isolation of the air in the polar vortex and thus hole starts to close.
  • As air from the surrounding latitudes mixes into the polar region, the ozone-destroying forms of chlorine disperse.
  • The ozone layer stabilizes until the following spring.

Ozone Layer

  • Ozone is a molecule of 3 oxygen atoms which sits in our planet’s stratosphere between 15 and 30 kilometres above the earth surface.
  • They are constantly formed and destroyed in the stratosphere.
  • Ozone layer absorbs a portion of the radiation from the Sun and prevents UVB radiation from reaching the Earth that might harm living beings.
  • The total amount of ozone in the layer would remain constant over time if there aren’t any human induced impacts.
  • Human made chemicals which releases bromine (Br) and chlorine (Cl) atoms react with ozone and breaks it down and thus the rate of destruction becomes faster than rate of creation of ozone.
  • The Montreal Protocol of 1989 brought together world governments to protect the ozone layer by phasing out many ozone-depleting substances (ODS).
