Chronic hunger:

It is a consequence of diets persistently inadequate in terms of quantity or quality. Poor people suffer from this type of hunger because of their very low income. For example, the income of landless labourers is too low to buy sufficient food. This type of hunger exists when a person is incapable of buying food even for survival. 

Seasonal hunger:

It is related to the cycles of growing and harvesting food. It is prevalent in rural areas because of the seasonal nature of agricultural activities and in urban areas because of casual labour. For example, there is less work for casual construction labour during the rainy seasons. This type of hunger exists when a person is unable to get steady work for the entire year.
