Nigeria's Northwest region has been devastated by protracted conflict stemming from the activities of bandits. Driven by economic opportunism, these groups have engaged in various activities, including kidnappings for ransom, cattle rustling, and thefts. This has resulted in the deaths of thousands and the forced displacement of several others across the region. The (under)governability of the sub-national state borders has exacerbated the crisis in the region, reinforcing the scourge of banditry and creating a transnational humanitarian crisis. This situation has been further complicated by the outbreak of COVID-19. Such incapacitation contributes to the complex problems of banditry, transnational crime, and forced displacement across the region, compounded by cross-border linkages with neighbouring Niger Republic. Previous research has primarily focused on the drivers and outcomes of transnational organized crime. However, this chapter contributes to the literature by examining the efficacy of border governance at sub-national levels as a countermeasure to the transnational threat of banditry. The chapter further analyses the challenges, and prospects of sub-national border governance in Nigeria’s northwest region in the aftermath of COVID-19 outbreak. The chapter utilizes secondary data sources from the Nigerian Security Tracker (NST), newspapers, reports, and journal articles.
