Famine is a severe, long-term hunger that affects a large proportion of the population in a country or region. Wars have been the cause of several famines throughout history.

The prevailing hypothesis for the occurrence of famines until the 1980s was a decline in food production. Amartya Sen proved that the most likely cause is what he called “failure of entitlement” and that famines are not necessarily the result of a decrease in foodProduction. The main cause of the Bengal famine of 1943 was inflation resulting from the war.
