Universal PDS to ensure food security?

Amartya Sen had suggested that the Government must revert to Universal Public Distribution System (PDS) to ensure effective food security rather than the targeted distribution proposed by the Government. A quick math on the expenses to be incurred, by the  Centre for Budget and Governance Accountability (CBGA) reveals that Universal PDS would not deplete the budget as feared. The CBGA also favours the Universal PDS as an effective tool to ensure Food Security.
