Intensive fish farming of fin-fish in open net-pens results in the release of organic and inorganic effluents like carbon, nitrogen and phosphorus to the environment. Accumulation of these effluents into the marine system can negatively impact the ecosystem by contributing to eutrophication of pelagic systems, fertilisation of benthic macrophytes in the euphotic zone, and organic enrichment of deeper benthic systems.
After 3.5 years of interdiciplinary research the partners of the Sino-Norwegian bilateral research Project:
Watershed Eutrophication management in China through system oriented process modelling of Pressures, Impacts and Abatement actions
will present their findings and policy relevant recommandations.
The presentations will be given before lunch. After luch there will be arranged a visit to the water work that cleans the water re-routed fron the Yantze watercourse.
China has for centuries struggled with eutrophication and has acquired much knowledge that will be of great value and benefit in order to understand the problem in Norway. We have therefore invited our main partners in the SinoTropia project to the seminar to share their experiences with us.
Impact assessments of changes in environmental pressures require improved system and process understanding to reach the knowledge level needed for sustainable water resource management as well as meeting future demands from EU Water Framework Directive (WFD). Both conventional and WFD resource management require a catchment-oriented approach to integrate processes. Furthermore, political feasibility of abatement actions and policy options need to be assessed. Considerable resources are spent over the past 10 years on abatement actions along the Morsa watercourse. Climate change and reduction in acid rain has significantly disguised the effect of these measures. Without these environmental changes the effect of the abatement actions would likely have been greater. Sub-optimum abatement actions are now needed in order to reach the water quality goals in Vansjø. Knowledge of how environmental pressures govern the eutrophication is important in order to achieve consensus for these actions
