In 1996 the Food and Agriculture Organization (FAO) of the United Nations (UN) estimated that the world was producing enough food to provide each person with 2,700 calories per day. Each day an average grown man needs around 2,500 calories per day, a grown woman around 2,000 calories, and children less. In other words, in the mid-nineties, there was more than enough food to keep everyone in the world adequately fed. Yet nearly 1 billion people, around 17 percent of the population at that time, were undernourished. What was happening?
According to the FAO, undernourishment occurs when, for at least a year, a person is unable to eat enough calories to meet the minimum energy needs of an inactive lifestyle. It does not take into account the needs of those who have a physically active life, such as farmers or manual laborers, and therefore need more calories to stay strong and healthy. Nor does it take into account deficiencies in essential vitamins and minerals which can have negative long-term effects on health, such as weak bones and skeletal deformities caused by a lack of vitamin D.
Based on the latest country data on population numbers, availability and distribution of food, and the ability of people to afford and physically access that food, the 2012 FAO report,’The State of Food Insecurity in the World‘ reveals a lot about undernourishment around the world over the past two decades.
