This is now a conventional concept of food security. Famine and Hunger Food security, on the one hand, and famine and hunger on the other, are inversely related concepts. Ensuring food security is equated to avoidance of famine and hunger. Famine and hunger result from the lack of food security. Famine is an absolute lack of food affecting a large population for a long time period.
Famine is a disaster of food insecurity.
This is famine. This tragedy can be avoided. In other words, the predictability of famine makes it possible to prevent it. If a food shortage develops to the scale of a famine, it must therefore be the weakness of society in general and government in particular. Hunger is not famine.
