When there is a disaster or a calamity, the production of food grains decreases in the affected area. This in turn creates a shortage of food in the area. Due to the food shortage, the prices go up. The raised prices of food materials affect the capacity of many people to buy the same. When the calamity occurs in a very wide spread area or is stretched over a long period of time, it may cause a situation of starvation. A massive starvation can take the form of famine.
