Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [1] and eventually, death. The term inanition [2] refers to the symptoms and effects of starvation.
In the field of hunger relief, the term hunger is used in a sense that goes beyond the common desire for food that all humans experience, also known as an appetite.

It has been reported that approximately 3 million rural households are food insecure, which is equal to 15 percent of the total population of rural households. [21]
However, the rates of decrease are not sufficient to meet the first Millennium Development Goal of halving hunger between 1990 and 2015. [55] The global financial, economic, and food price crisis in 2008 drove many people to hunger, especially women and children.
There has been a global increase in food insecurity and hunger between 2011 and 2020. In 2015, 795 million people (about one in ten people on earth) had undernutrition. [9] [42] It is estimated that between 691 and 783 million people in the world faced hunger in 2022. [43]
The relationship between the two concepts is not straightforward. For example, "freedom from hunger" (which General Comment 12 designates as more pressing and immediate [14]) could be measured by the number of people suffering from malnutrition and at the extreme, dying of starvation.
