Eutrophication is one of the most important anthropogenic pressures impacting coastal seas. In Europe, several legislations and management measures have been implemented to halt nutrient overloading in marine ecosystems. This study evaluates the impact of freshwater nutrient control measures on higher trophic levels (HTL) in European marine ecosystems following descriptors and criteria as defined by the Marine Strategy Framework Directive (MSFD). We used a novel pan-European marine modeling ensemble of fourteen HTL models, covering almost all the EU seas, under two nutrient management scenarios. Results from our projections suggest that the proposed nutrient reduction measures may not have a significant impact on the structure and function of European...

Interaktive Programmierungsansätze für die Gestaltung von Agrar- und Umweltprogrammen AgEcon
Kirschke, Dieter; Jechlitschka, Kurt.
Planning agricultural and environmental programmes has become a complex task. In this paper we show how interactive programming can help to solve such complex policy decision-making problems. The basic linear programming model is implemented with Excel. We show, for a hypothetical agricultural and environmental programme, how the approach can be used in an interactive way between scientists and policy decision-makers. The approach allows to visually demonstrate and quickly assess the consequences of changing assumptions and framework conditions on the programme design. It could effectively improve the quality of policy decision-making support; it requires the actors’ willingness, of course, to engage in a real dialogue.
Tipo: Journal Article Palavras-chave: Agricultural and environmental programmes; EU agricultural policy; Decision-making support; Linear programming; Policy support; Agricultural and Food Policy; Environmental Economics and Policy.
