The Global Hunger Index (GHI) is a method for systematically assessing and monitoring hunger on a global, regional, and national level. European NGOs of Concern Worldwide and Welthungerhilfe are responsible for preparing the GHI. Global Hunger Index scores are calculated on the basis of values of four components that are undernourishment, child stunting, child wasting, and child mortality. Every set of GHI scores is based on data from a 5-year period and is included in the GHI’s yearly report. Data from 2017 through 2021 are used to determine the 2022 GHI scores. The GHI Index for 2022 indicates that India has a severe hunger issue. The primary causes of this are poverty, gender inequality, lack of immunization, illiteracy, lack of awareness, as well as extreme climate change. The climate issue has an impact on the global food system on all fronts, from production to consumption. It influence food production, availability, diversity, access, and safety further by destroying land and crops, harming livestock, depleting fisheries, and braking off transport to markets. Several actions have taken to mitigate the consequence of climate catastrophe and hunger viz. transformation of the food system through diversification of cropping patterns towards millets, pulses, oil seeds; the adoption of food crops that are climatically adaptable like millets for nutritional security etc.
