A Cross-disciplinary Integrated Eco-systemic Eutrophication Research and Management Approach: CINTERA

Awarded: NOK 4.0 mill.

-

This is a cross-disciplinary study that will examine eutrophication driven by aquaculture in Norway and in Chile. It focuses first on establishing the basic scientific knowledge necessary for the management of eutrophication by filling in important gaps in knowledge about how nutrient and organic wastes from aquaculture systems distribute and accumulate in ecosystems, and how these nutrients and organic matter affect the structure and function of the ecosystem. Two sets of cases are selected: Hemnfjord and Frøya fjord (Hitra) (both in Sør Trøndlag) with high aquaculture activities, and some control cases in the same region with little aquaculture; and two fjords located in the Commune of Hualaihué, in region X of Chile (Región de los Lagos), correspond ing to the bio-geographical Province of Magallanes. Comparing the two fjord systems will allow us to examine a wide variety of conditions such as pH differences between Chilean and Norwegian Fjords and hence pursue potential interaction between ocean aci dification and eutrophicaiton. Samples will be collected during will be four seasonal cruises in Norway and two in Chile and analyzed in Norway and Chile. The project also adds a socio-economic component by assessing the ability of selected local communi ties in the study areas in Norway and Chile to adapt to eutrophicaton/aquaculture by looking at eutorphication/aquculture's potential to create conflict among stakeholders. This too is a comparative approach, allowing for comparisons across different eco logical and managerial settings, time and space. The concept of Consilience, the linking together and centering of principles and knowledge from different disciplines and sectors, is the foundation of the CINTERA project and is a signifier for its compar ative (ecosystems, socio-economic systems) and cross-disciplinary character: There will be close cooperation among natural and social scientists in three countries: Norway, Chile, and the United States.
