The World Food Programme (WFP) Live Hunger Map monitors food security in more than 90 countries and issues predictions where data is limited. The live map aims to identify areas that are currently food insecure or are sliding towards food insecurity. A static hunger map can be found if you click on "undernourishment" at the bottom of the page. It includes data from 2017-2019.
