Description du projet
Réduire la pollution par les nutriments grâce aux meilleures pratiques
La réduction de la pollution par les nutriments et de l’eutrophisation de l’eau est cruciale à la préservation des écosystèmes côtiers. Le projet NAPSEA, financé par l’UE, aidera les autorités nationales et locales à choisir des mesures efficaces de réduction de la charge en nutriments en vue de limiter l’incidence délétère de ces derniers sur les eaux intérieures et côtières. Le projet adoptera une approche intégrée visant à lutter contre la pollution par les nutriments depuis sa source dans les fleuves jusqu’à la mer, en utilisant le système côtier regroupant le Rhin et l’Elbe ainsi que la mer du Nord comme étude de cas. En se concentrant sur la gouvernance, le parcours des nutriments et la santé des écosystèmes, NAPSEA évaluera des scénarios de réduction des nutriments grâce à un cadre de modélisation intégré et définira des limites écologiques sûres.
Objectif
The central aim of the proposed Source to Sea (NAPSEA) CSA is to support national and local authorities in selecting effective nutrient load reduction measures and to gain political support for the implementation. The consortium partners have been closely involved in applied research and implementation of nutrient reduction measures at local, national and European level. In NAPSEA the current challenges to reduce nutrient pollution, eutrophication and its negative impacts on inland and coastal waters and their ecosystem services will be addressed by an integrated approach addressing nutrient pollution from river source to sea, using the Rhine and Elbe Rivers-North Sea coastal system as case study and integrating three complementary perspectives: governance, nutrient pathways & measures, and ecosystem health. Each of these perspectives provide an essential part of the solution to achieving a healthy ecosystem with measures that are societally acceptable and cost-effective. We will identify options to reach a harmonized approach in nutrient reduction measures across different geographical areas and policy frameworks (governance), select and evaluate nutrient reduction scenarios with an integrated modelling framework from source to sea (nutrient pathways) and define safe ecological boundaries for different types of ecosystems along the continuum from catchment to coast (ecosystem health). NAPSEA will showcase the best practices and consider obstacles on the implementation of socially acceptable, sustainable and effective measures for several local case studies within this geographical scope, also taking into account effects of climate change. These case studies accommodate the variability in potential threats of eutrophication as well as feasibility, effectiveness and implementation of potential measures to represent different ecosystem types, with varying eutrophication symptoms, and address different socio-economic and governance scales from local to European level.
