What is Global Hunger Index (GHI)?

Definition:
  • The Global Hunger Index (GHI) is a multidimensional statistical tool used to describe the state of countries' hunger situation.
  • It is released annually by IFPRI since 2006. It ranks countries on a 100-point scale. Zero on the scale is the best score (no hunger), and 100 is the worst. 
  • It highlights successes and failures in hunger reduction and provides insights into the drivers of hunger. Thus, GHI aims to trigger actions to reduce hunger. 
  • The GHI is calculated by taking into account four indicator parameters. 
  • They are :-- 
  • (i) Undernourished population (1/3rd weight), 
  • (ii) Child wasting (1/6th weight), 
  • (iii) Child stunting (1/6th weight) 
  • iv) Infant mortality rate (1/3rd weight).
  • It descrebes India's hunger situation as "serious." On a 0-100 point scale with 100 being the absolute worst in hunger levels, India scored 28.5 - a marginal improvement of a quarter point since the turn of the century.
  • But with the country all set to be the most populaous in the world in the next 10-odd years, the improvement may well reverse.
