Food security is defined as having access to sufficient, safe, and nutritious food. The FAO and WHO work to address food security globally. The FAO leads international efforts against hunger and India is a founding member. The WHO works on health issues and India joined in 1948. Definitions of food security have evolved over time to include availability, accessibility, affordability, and stability. The four pillars of food security are availability, access, utilization, and stability according to the FAO. India faces issues with over 200 million undernourished people and the government has implemented programs to address food security such as PDS, MDM, and employment guarantees.
