The public distribution system (PDS) in India aims to ensure food security for the country's population through the timely procurement and subsidized distribution of food grains. The PDS is managed jointly by the central and state governments. Food grains are procured by the Food Corporation of India and transported to local fair price shops, where ration cards are used to provide subsidized grains and other items to India's poor and needy populations at an affordable price. However, the system faces limitations like poor identification of beneficiaries and uneven distribution of food grains.
