In light of rising forced global migration and disproportionately high levels of poverty among migrants, immigration systems have come to be understood as drivers of food insecurity in higher-income countries. At present, the mechanisms through which this operates are not well understood. The complex nature of immigration systems and statuses mean that experiences of migrant food insecurity are highly situated. There is a pressing need to examine, theorise and measure how these manifest in order to inform effective intervention and policy. In this article, we focus on the UK context to identify potential directions for the evolving food insecurity research agenda around forced migration. We outline how certain immigration statuses (trafficked, asylum seeker and refugee) intersect with different physical settings (rural/urban) to produce specific forms of food insecurity that urgently warrant further attention.
