Factors affecting food security

In 2008 the prices of many foods increased. Wheat and rice were two key examples and increased by 130% and 75% respectively. This caused riots in over thirty countries. Similar riots are still occurring. In 2016 over 400 people were arrested in Venezuela after rioting and looting over food shortages.

The United Nations Food and Agriculture Organisation (FAO) records the prices of five key products: cereals, vegetable oils, dairy, meat and sugar. They compare this with different factors and produce an annual report called 'The state of food insecurity in the world'. The graphs below come from the 2015 report.
