Social farming is a much-studied concept in the European Union, but debates continue on the issues of standardised content and terminology. Therefore, this study involved an empirical analysis of various social farming concepts, outlining a way in which relevant rules can be designed at the European level. Various models of social farming were empirically analysed, with a focus on the (a) aim of the organisation, (b) actors within and outside the organisation, and (c) communication and decision-making structures. This study demonstrates that a European-level legal act should be adopted to achieve standardisation; however, full harmonisation is not desirable, at least not at present. It will be necessary to oblige Member States to catalogue specific activities to be covered by the term social farming in a given legal system. The pivotal point here is the multifunctional idea of agriculture, which ultimately means that social agriculture will have to support traditional agricultural activities, an approach that could be used to promote social farming systematically. The main feature of this proposal is the implementation of an open, subsidiary approach to do justice to the versatility of social farming.
