Abstract
This study examines Boko Haram terrorism and its implications for security and sustainable development in Nigeria. Boko Haram’s insurgency, driven by religious extremism, political exclusion, and socio-economic deprivation, has significantly undermined Nigeria’s national security and territorial integrity. The violent activities of the group have resulted in widespread displacement, loss of lives, and the destruction of critical infrastructure, particularly in education, healthcare, and agriculture sectors, thereby hindering sustainable development in affected regions. Using a qualitative approach with a historical research design, the study analyzes secondary data to explore the causes, impacts, and responses to the insurgency. Findings reveal that despite government and regional efforts to combat Boko Haram, challenges such as poor coordination, corruption, and inadequate rehabilitation programs limit the effectiveness of these strategies. The study underscores the need for integrated security measures combined with socio-economic development and inclusive governance to achieve lasting peace and sustainable progress in Nigeria.
