The effectiveness of academics in Nigerian universities has increasingly been challenged by multifaceted factors rooted in security instability, political interference, and economic constraints. This study examines the extent to which these factors influence academic productivity, teaching quality, and research output within the Nigerian higher education system. Utilizing a quantitative research design, data were collected from academic staff across selected federal and state universities in Nigeria through a structured questionnaire. Exploratory Factor Analysis (EFA) was employed to identify underlying dimensions of the challenges faced by academics. Findings reveal that insecurity, including campus-related violence and regional conflicts, significantly disrupts academic activities and psychological well-being. Political factors, particularly government interference, policy inconsistency, and institutional governance issues, further constrain academic autonomy and performance. Economic challenges, such as inadequate funding, poor remuneration, and lack of research grants, emerged as the most critical determinants of reduced academic effectiveness. The study concludes that addressing these systemic challenges is essential for improving the global competitiveness and productivity of Nigerian universities. Recommendations are provided for policymakers, university administrators, and stakeholders to foster a conducive academic environment.
