The home page at http://fews.net provides regularly updated reports and maps of the food emergency status of selected countries.

Food Security Classification provides shapefiles of current emergency situations (although they often tend to lag the reports on the main page). This data can be downloaded by region or all of the current and historical data can be downloaded using Download All Data.
