Spatial Co-Occurrence of Oil Spills and Gas Flare Hotspots in the Niger Delta, Nigeria
Keywords:
Oil spills, Gas flares, Spatial analysis, Spatial clustering, HotspotsAbstract
In this study, we conducted spatial analyses to examine the co-occurrence of oil spills and gas flare hotspots within the Niger Delta region. Utilizing Geographic Information Systems (GIS) and statistical methods, such as; Average Nearest Neighbor, Multi-Distance Cluster Analysis, Chi-square test, and Pearson correlation analysis, the research analyzed the distribution, clustering, and associations between oil spill hotspots, gas flare site hotspots, oil spill density, and gas flare density. The findings revealed significant spatial clustering of oil spill and gas flare hotspots, particularly in Imo, Rivers, Bayelsa, Delta, Edo, Akwa-Ibom, and Abia States. Pearson correlation analysis indicated moderate to strong linear relationships between oil spill hotspots, gas flare site hotspots, oil spill density, and gas flare density; suggesting potential spatial co-occurrence or associations between these environmental phenomena. These findings have implications for targeted interventions and regulatory measures aimed at mitigating environmental risks and vulnerabilities in the Niger Delta region, ultimately promoting sustainable development and environmental stewardship in the area.
