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.
