This paper provides background information for a database and typology on volatility and food nutrition security (FNS) relevant for modeling volatility effects on FNS. First, the data sources and derived indicators are discussed. Second, the typology consisting of three dimensions ‘potential’, ‘efficiency’ and ‘FNS risk’ is described and visualized in geographical maps and tables for each sub-indicator of the three dimensions. The linkages between the sub-indicators are also explored. Finally, a global mapping of hunger and volatility is provided to identify countries that are severely affected by malnutrition and/or market instability.
