In the body, discuss the various challenges like incapacity of the government to procure all the grain, the danger of making agriculture internationally uncompetitive, inefficiency in agriculture, leakages in subsidy. In the next part discuss the various challenges in grain handling by the FCI like wastage, leakage, handling cost, etc.
Conclude by mentioning the need to avoid the legal provision to the MSP and increasing the grain handling efficiency.
