  Food insecurity, defined as the lack of physical or economic access to safe,
nutritious and sufficient food, remains one of the main challenges of the 2030
Agenda for Sustainable Development. Food insecurity is a complex phenomenon,
resulting from the interplay of environmental, socio-demographic, and political
events. Previous work has investigated the nexus between climate change,
conflict, migration and food security at the household level, however these
relations are still largely unexplored at national scales. In this context,
during the Complexity72h workshop, held at the Universidad Carlos III de Madrid
in June 2024, we explored the co-evolution of international migration flows and
food insecurity at the national scale, accounting for remittances, as well as
for changes in the economic, conflict, and climate situation. To this aim, we
gathered data from several publicly available sources (Food and Agriculture
Organization, World Bank, and UN Department of Economic and Social Affairs) and
analyzed the association between food insecurity and migration, migration and
remittances, and remittances and food insecurity. We then propose a framework
linking together these associations to model the co-evolution of food
insecurity and international migrations.
