This journal article examines the relationship between sexual and gender‑based violence (SGBV) and cross‑border migration from Sudan to South Sudan amid protracted and intensifying conflict. Drawing on mixed‑methods research at the Sudan–South Sudan border, it shows how SGBV operates both as a driver of migration and as a continuing risk during flight and settlement, particularly for women and adolescent girls. By tracing shifting patterns of harm across conflict, migration and reception settings, the article highlights the transboundary nature of violence and the uneven protection landscapes migrants encounter. It calls for prevention and response strategies that address the continuum of violence across borders while centring survivors’ experiences and agency.
