The correct option is (d).
Explanation
Food security is defined by three essential dimensions: Availability, Accessibility, and Affordability. The concept of 'Availability of food' specifically refers to the quantitative supply of food grains within the country at a particular point in time.
Statement-wise Analysis:
- Statement 1 is Correct: Domestic food production is the foundational component of food availability. It represents the total output of food grains produced within the country's geographical boundaries during an agricultural year.
- Statement 2 is Correct: Food imports are added to the domestic supply to calculate total availability. Imports are essential to bridge the gap between domestic production and demand, ensuring stability in supply.
- Statement 3 is Correct: Previous years' stock in government granaries (buffer stocks) is a critical component. These stocks, maintained by agencies like the Food Corporation of India (FCI), are released to maintain availability during periods of low production or natural calamities.
Key Takeaway:
The mathematical definition of food availability is: Availability = Domestic Production + Net Imports + Change in Government Stocks.
