Famine scales are like levels of hunger. They measure how bad a famine is and how likely it is to cause serious health problems like death. Level one is mild hunger, level two is moderate hunger, level three is severe hunger, level four is extreme hunger and level five is the worst type of famine. Level five means a lot of people in the area suffer from malnutrition and may even die from it. Famine scales help people understand how severe a famine is, so aid and help can be given to the people who need it.
