Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life. In a global scenario where hunger and obesity affect millions of people, public actions have been developed towards Food and Nutrition Security (FNS). In 1996 during the World Food Summit, 186 countries signed the Rome Declaration, committing themselves to assess and address Food and Nutrition Insecurity. In this exploratory study, we compile secondary internet data using keywords in four languages to map the global distribution, among signatories, of FNS public initiatives and assess their association with key national-level socioeconomic indicators. As a result, we found FNS public policies in 123 countries, reports on the state of FNS in 139 countries, and the presence of both in 114 countries (61%). The proportion of countries with any type of, as well as with specific, FNS policy or diagnostic was higher in least developed countries. There was a statistically significant association between these proportions and selected national-level socioeconomic variables. The results are discussed along with population vulnerability, international cooperation mechanisms and political discourse and how these factors impact the existence of FNS public actions.
