4 TASK II - ENVIRONMENTAL CONSIDERATIONS
90. The major environmental constraints and issues identified in this report and the planning reports for a railway and highway to a potential Cape Cross Port have to be supplemented by detailed environmental assessments at the planning phase for a Namibian North Coast Port.
91. The EIA during the pre-feasibility stage for such a port has revealed no insurmountable environmental problems, especially also for the seal colony at Cape Cross which most probably would not be threatened by the development of a port in the area. The commercial port would be located to the north-east of the main colony, the fishing port, if separate, to the south and industrial and human settlement inland to the east.
92. Although the individual environmental effects may individually represent small impacts only, their cumulative, synergistic or secondary effects when considered together may amplify one another to an unexpected degree. A broadly-based environmental impact assessment can help to identify such effects.
