Food crisis occurs when rates of hunger and malnutrition rise sharply at local, national, or global levels.There are many reasons why people cannot grow or buy enough food to feed their families. Most of the reasons are caused by a combination of poverty, famines, increased global food prices, global fuel price rise, etc. A hunger crisis develops when families experience these stresses for several years and run out of ways to cope with them and governments and aid agencies fail to intervene. Food crisis thrives mostly in poor agricultural countries like India, Nepal, Srilanka, etc. Ultimately, the main reason for food crises is not that food is unavailable but the inability of countries, especially the developing countries to afford it.
