Abstract: The capacity of United Nations peacekeeping operations (PKOs) to protect civilians remains a core debate in international security. This quantitative study introduces a personnel density metric—defined as the number of active blue helmets per 100 square kilometers of conflict zone—to assess its direct impact on minimizing civilian casualties. Utilizing a longitudinal dataset encompassing 14 African conflicts from 1995 to 2008, we employ fixed-effects panel regression models to isolate PKO impacts from confounding political variables. The statistical results demonstrate a robust threshold effect: when peacekeeping personnel density exceeds 12.5 troops per 100 square kilometers, civilian fatalities decrease by an average of 42% (p < 0.001). Conversely, low-density missions (fewer than 4.0 troops per 100 square kilometers) show no statistically significant difference in casualty rates compared to unmonitored zones. Analysis also indicates that robust chapter VII mandates enhance troop efficacy by a factor of 1.8 ± 0.3 relative to observer missions. The study concludes that international interventions must meet minimum deployment thresholds to move past symbolic presence and achieve real protection.
