What is the need of food securit ? how is food security affected during a calamity ?

food security is necessary because-

a) availability of food means food production within the country, food imports and the previous years stock stored in government granaries.

(b) accessibility means food is within reach of every person.

(c) affordability implies that an individual has enough money to buy sufficient, safe and nutritious food to meet one's dietary needs.

during natural calamity-

• the total production of food grains decreases
• there is a shortage of food in affected areas
• due to shortage of food prices go higher
• this would led to black marketing and hoarding which may further decreases the supply

Thus, food security is ensured in a country only if

(1) enough food is available for all the persons

(2) all persons have the capacity to buy food of acceptable quality and

(3) there is no barrier on access to food.
