The main goal of the project was to assess nitrogen pollution of surface waters and groundwater in the Federal State of North Rhine Westphalia (NRW), Germany. For this purpose the hydro(geo-)logical models GROWA-DENUZ/WEKU were coupled to the agro-economic model RAUMIS in order to assess the...

For around 20 years, the sustainability concept and its implementation have been discussed by society at large (Kobiowu et al., 2005; Goldblatt, 2005; Marechal et al., 2005; Backstrand, 2006; Spangenberg, 2005) and, among others, by the green economics community (Lunn, 2006; Kennet and Heinemann, 2006b; Dobson and Bell,...

The Weser River Basin will most likely not meet European water framework directive nitrogen concentration targets by 2015. We use the AGRUM model network connecting hydrological and nutrient transport models with a German agricultural sector model to analyse current and future nitrogen surplus...

Soil erosion on arable land and on steep vineyards is a major problem in the state of Hesse (21,115 km²) in central Germany. The aim of a joint study between the Research Centre Jülich, the Hessian Agency for the Environment and Geology and the Hessian Ministry for the Environment, Energy,...

Die Europäische Wasserrahmenrichtlinie (EG-Wasserrahmenrichtlinie 2000) hat zum Ziel in den Flusseinzugsgebieten Europas das Erreichen eines guten Zustands bzw. des guten ökologischen Potenzials und des guten chemischen Zustands aller Oberflächengewässer sowie des guten mengenmäßigen und...

The objective of the paper is to show the potential of interdisciplinary model networks consisting of agricultural economic and natural science models performing integrated impact assessments of agri-environmental policies. The potentials are exemplified using a coupling of the agricultural...
