Keynote: Blue Economy - Environmental and Behavioural Aspects Towards Sustainable Coastal Development

The aim of Blue Economy models are to shift society from scarcity to abundance – based on what we have, and to start tackling issues that cause environmental and related problems through novel ways. Some major factors that cause ecological alterations to coastal and surface waters and contribute to nutrient inputs include municipal wastewater and storm water discharges; combined sewer overflows; other urban runoff; agricultural runoff; aquacultures; and various others. The issue of nutrient input due to aquaculture, being a serious input source in developing countries, is emphasized together with actual measurements and control techniques applied in EU. Other general quality issues in coastal and aquaculture environments are presented within the scope of blue economy principle and thus suggesting novel actual management techniques.
