This paper examines the influence of banditry and kidnappings on infrastructural development in Adamawa State. The study employs a descriptive survey research design. The population of the study includes residents of affected communities (315), government officials (21), and security personnel such as the Nigerian Police Force and Nigerian Security and Civil Defense (42), and community leaders (21). The total target population for the study is 399, derived from Taro Yamane’s (1967) formula, ensuring statistical reliability and validity. The study utilized convenience sampling techniques to select respondents from the target population and used quantitative data. Regression analysis was carried out to examine the statistical significance between the variables. The regression analysis reveals that a unit increase in banditry and kidnapping significantly diminishes infrastructure development by -0.168 (p < 0.000), indicating a strong negative relationship between insecurity and infrastructure development. Additionally, the frequency of banditry has a statistically significant positive effect (0.827, p = 0.001), showing that more frequent banditry exacerbates the negative impact on infrastructure. The socio-economic well-being of communities was found to have a negligible and statistically insignificant effect on infrastructure development (-0.002, p = 0.974). Conversely, the study highlights that an increase in policies and strategies significantly improves infrastructure by 0.374 (p < 0.000), suggesting that effective policy interventions can mitigate the adverse effects of insecurity and foster infrastructural development in the state. The study concludes that banditry and kidnappings are major barriers to infrastructure development, but targeted policies and strategies are essential for mitigating these challenges and promoting growth and development in Adamawa State.
