This research examines the complex nexus between terrorism and trans-border migration in North-East Nigeria, with specific attention to the operations of Boko Haram. The study analyzes how porous borders, weak institutional control, and long-established cross-border migration networks linking Nigeria with neighboring countries have been exploited by the insurgent group to facilitate recruitment, movement of fighters, arms smuggling, and logistical coordination. These dynamics have contributed significantly to Boko Haram’s resilience and territorial expansion within the Lake Chad Basin region. The insurgency has severely destabilized local communities, resulting in widespread violence, economic disruption, and the collapse of livelihoods. As a consequence, millions of people have been forcibly displaced, either as internally displaced persons or as refugees seeking safety across international borders. This large-scale displacement has deepened the humanitarian crisis and heightened the vulnerability of affected populations, particularly women and youth, to exploitation and radicalization. The study argues that addressing the interlinked challenges of terrorism and trans-border migration demands a holistic and coordinated response. Beyond conventional military and security measures, effective solutions must incorporate strengthened border governance, regional cooperation, targeted humanitarian assistance, and inclusive long-term development initiatives. Addressing underlying drivers such as poverty, marginalization, and weak governance is essential for mitigating forced migration, undermining extremist recruitment, and promoting sustainable peace and stability in North-East Nigeria.
