The Cameroon-Nigeria border is plagued with insecurity challenges and serious threats to the border communities. Following the Boko Haram attacks, the counter-offensive by the Cameroonian and Nigerian armed forces, and the attacks between the Southern Cameroons separatists and the Cameroonian forces as a result of the Anglophone Crisis, the population along the Cameroon-Nigeria border were forced to abandon their towns and villages into neighboring communities. This forced-migration has orchestrated the influx of refugees into both Cameroon and Nigeria, and internal displacement of many people. This article traces the complex insecurity situation that prompted forced migration and massive internal displacement of populations which paralyzed border activities. A qualitative methodology was employed in this study wherein both questionnaire and interview guide were used as instruments of data collection. Questionnaires were self-administered to the locals who were highly affected. Interviews were conducted with key informants along the Cameroon-Nigeria border. The descriptive and analytical approaches to assess documents on complex insecurity situations that resulted from the activities of the Boko Haram Terrorist Group and the Anglophone Crisis were employed. The study recommends that, any peace process that ignores the needs and roles of the border communities is unnatural, and therefore inherently unstable. The contention here is that Cameroon and Nigeria need to cooperate for effectiveness in border policy with greater attention to the endeavors of border communities.
