Sustainability of port activities within the framework of the fisheries sector: Port ofVigo(NW Spain)

摘要

Sustainability of the fisheries sector is nowadays a key issue due to the significant impact that this activity may have on the environment. Besides fishing activity itself, other indirect impacts, like those originated from related activities and services also need to be addressed. For assessing the environmental burden of this sector, the Ecological Footprint (EF) indicator can be used. The application of EF to the fisheries sector is still uncommon and studies of associated activities (such as ports) even more. In this work, classical EF methodology was applied in order to evaluate the environmental impact of the fisheries sector, taking as a representative sample the global activity (fishing and transportation) of the Port of Vigo (Spain), one of the biggest fishing ports in the world. A high value of total EF for both port and fishing activities was obtained. However, relative EF is much higher in the case of fishing, due to the low natural productivity associated to fish resources. Energy-land and sea area were the most affected land-components within the footprint, while among the different categories, resources consumption was the main contributor to the EF value in all the assessed scenarios.
