The Public Distribution System (PDS) in India is designed to ensure food security by distributing essential commodities like wheat, rice, sugar, and kerosene at subsidized prices to the poor. Its main objectives include controlling prices of essential goods, reducing fluctuations in market prices, and ensuring that these goods are equitably distributed to vulnerable sections of society. By doing so, the PDS aims to provide food security, stabilize prices, and support the welfare of the poor.
