Abstract: The study determines, the dominant human activities and environmental attributes as a guide to coastal planning and management in the Niger Delta region of Nigeria. Data used for the analysis was collected within 3 years between 2002 and 2004. A total of 21 human and environmental variables were used for the study. Principal component analysis was carried out on the sets of data obtained. To determine the dominant human activity variables as well as the environmental components the 2 sets of data were correlated using stepwise multiple regressions. The result shows that agriculture (crop and fisheries), deforestation and human population are the major human activities impacting on the coastal environment with resultant pollution and environmental degradation. The study recommends that these activities be properly planned for and controlled in a well articulated integrated coastal planning and management framework to achieve a healthy balanced.
