Cooperation in farming (co-farming) is an integrated cooperation between two or several independent farms. Co-farming allows farmers to redress disharmonies on the existing farms. Theses farms in the long run will be able to utilize economies of scale which would not have been possible in a continuing production. This is some of the preliminary findings from a Danish case-study in which nine co-farming groups (22 separate farms) were involved. These groups were followed in the initiating founding phase. In advising the potential participants in co-farming a model with a coordinated focus on cooperating conditions and their economic consequences have been used. In more integrated co-farming constructions, this model is shown to be suitable in giving farmers a certain overview of the consequences of creating a share-farm arrangement.
