Environmental disasters have become persistent challenges in the Niger Delta region of Nigeria due to oil exploration, gas flaring, pipeline vandalism, flooding, and industrial pollution. Environmental Impact Assessment (EIA) serves as an important environmental management mechanism for predicting, mitigating, and controlling the environmental consequences of developmental activities. This study examined the place of Environmental Impact Assessment in environmental disaster management in the Niger Delta region of Nigeria. Specifically, the study investigated the extent to which EIA contributes to environmental disaster prevention and analyzing the factors that hinder the effectiveness of EIA implementation in managing environmental hazards in the Niger Delta. A descriptive survey research design was adopted. A sample size of 240 respondents comprising environmental officers, oil company workers, community leaders, and environmental activists was selected from Rivers, Bayelsa, and Delta States using stratified and simple random sampling techniques. Data were collected using structured questionnaires and analyzed using mean statistics and Analysis of Variance (ANOVA). Findings revealed that EIA significantly contributes to pollution control, environmental monitoring, disaster prevention, and sustainable environmental management in the Niger Delta region. Furthermore, the findings showed that factors hindering EIA in disaster management in the Niger Delta region of Nigeria included delays in environmental reporting, political interferences among others. The ANOVA result showed a statistically significant difference in respondents’ perceptions regarding the effectiveness of EIA in environmental disaster management (F = 7.82, p < .05). The study concluded that EIA plays a vital role in reducing environmental disasters in the Niger Delta despite challenges associated with poor implementation and weak regulatory enforcement. The study recomm- -ended stricter enforcement of EIA regulations increased community participation, and impr- -oved environmental monitoring systems
