This article examines the impact of insecurity on economic growth in the North-Eastern states of Nigeria, a region plagued by persistent violent conflicts, particularly due to Boko Haram insurgency, banditry, and communal clashes. The study investigates how these security challenges have hindered economic development by disrupting agricultural activities, trade, and investment flows, which are the primary economic drivers in the region. Using data from official reports, surveys, and relevant literature, the article highlights key factors such as displacement of people, destruction of infrastructure, and loss of livelihoods. It further explores the resulting decline in GDP, employment rates, and government revenue. The findings reveal that insecurity has not only stifled local economies but also led to severe poverty and increased dependency on humanitarian aid. The article concludes by proposing policy recommendations, including improving security infrastructure, promoting peacebuilding efforts, and fostering regional economic diversification to mitigate the long-term impacts of insecurity on economic growth in North-Eastern Nigeria.
