According to the 2019 UN Food and Agriculture Organization State of Food Security and Nutrition in the World , more than 820 million people were undernourished globally in 2018, and 704 million were severely food insecure. Food insecurity and undernourishment affect people in all regions, but the problem is particularly acute in sub-Saharan Africa, where the burden of HIV disease is also greatest. From 2015 to 2018 the region had a consistent rise in food insecurity and undernourishment. And in 2018, an estimated 258 million people (24·6% of the population) were severely food insecure with 605·8 million (57·7%) being moderately or severely food insecure.
