Organic farming in Austria has seen a rapid development as all over Europe. In some alpine regions over 50% of the farms have converted to organic. Thus the idea of forming “Eco-Regions” (“Bioregionen” in German), transforming organic farming values from a farm level to a regional scale, emerged. The paper presents the results of an action research based project to develop a model for the formation of Eco-Regions and to monitor the success in cross-sectoral networking. Besides a number of prerequisites also bottlenecks for the formation become apparent. The paper describes the model and the implementation in two distinct regions
