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,...
