This will be the basis for this workshop which aims to analyse the efficiency of organic and low-input systems concerning the use of land, nutrients, water energy, and climate change scenarios. Economic efficiency of different production systems with implication for markets and prices will be analysed. Furthermore, we will explore to which extend consumers value environmental benefits. %D 2008 %K Sustainability, nitrogen leaching, crop rotation, model simulation, catch crop %L orgprints13352
