Public Distribution System was started by Indian government to facilitate the supply of foodgrains to the poor at a subsidised price. The main purpose of PDS was to act as price supporting programmes for the consumers during the period of food shortage. It was considered as an instrument of price stabilization. Now, it is the key element of the government's food security system in India. It is an instrument for ensuring availability of certain essential commodities at easily affordable prices especially for the poor. The stock of foodgrains by Food Corporation of India, is released every month for distribution through PDS. Many poor people are benefitted by the scheme.
