The National Food Security Act of 2013 in India aims to provide subsidized food grains to about two-thirds of the population through various schemes, including the Public Distribution System and Midday Meal Scheme. It faces limitations such as inadequate grain supply per person, insufficient storage capacity, and challenges in household identification for eligibility. The food processing sector is expanding, offering opportunities for employment and agricultural integration but also facing challenges such as high capital requirements and competition from global markets.
