This page has a good summary of what hunger is:
“Acute hunger or starvation are often highlighted on TV screens: hungry mothers too weak to breastfeed their children in drought-hit Ethiopia, refugees in war-torn Darfur queueing for food rations, helicopters airlifting high energy biscuits to earthquake victims in Pakistan or Indonesia. These situations are the result of high profile crises like war or natural disasters, which starve a population of food, yet emergencies account for less than eight percent of hunger’s victims.”
The WFP includes famine vicitms in their definition of hunger. But famine accounts for less than 10% of persons with inadequate nourishment. The vast majority of the hungry have enough food for survival; that is why hunger is chronic, a continuous problem, rather than an intermittent one.
In my writings, I distinguish famine from hunger. But the WFP approach of categorizing the two together is also useful.
Note that the FAO uses 1800 kcal/day as a metric for determining who is hungry, but the WFP uses 2100 kcal/day. From a practical point of view, what is most important is raising the kcal/day by ensuring that people have sufficient quantity and quality of macronutrients.
