In agriculture, forestry and related sectors, multi-actor partnerships for ‘co-innovation’ occur in many forms, from international projects to informal ‘actor configurations’. Common attributes are that they include actors with ‘complementary forms of knowledge’ who collaborate in an innovation process, engage with a ‘larger periphery’ of stakeholders in the Agricultural Knowledge and Innovation System (AKIS) and are shaped by institutions. Using desk research and interviews, we reviewed, according to the Organisational Innovation Systems framework, the performance of 200 co-innovation partnerships from across Europe, selected for their involvement of various actors ‘all along the process’. Many of the reviewed partnerships were composed of actors that had previously worked together and most interviewees believed that no relevant actors had been excluded. In almost all cases, project targets and objectives were co-designed to a great or some extent, and the mechanisms applied to foster knowledge sharing between partners were considered to be very effective. Great importance was attached to communication beyond the partnership, not simply for dissemination but also for dialogue, and most interviewees evaluated the communication/outreach performance of their partnership very highly. Most partnerships received external funding, most did not use innovation brokers during the proposal writing process and two thirds had access to information they needed. We discuss the implications of these findings and question whether the AKIS concept as currently interpreted by many policy makers can adequately account for the regional differences encountered by co-innovation partnerships across Europe.</p></div>","PeriodicalId":49751,"journal":{"name":"Njas-Wageningen Journal of Life Sciences","volume":"92 ","pages":"Article 100335"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.njas.2020.100335","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88110161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that attitude was the main determinant of intention, followed by perceived behavioral control and injunctive norms. Results also showed that “Sell grains at higher price”, “Have independence in relation to grain storage firms”, and “Have control over grain classification” are the most important beliefs that drive attitude; “Bank” is the most important belief that drive perceived norm; and “Have easy access to silos”, “Prioritize other investments”, and “Need skilled workers” are the most important beliefs that drive perceived behavioral control.

The pros and cons of these rivalling ideas are rarely foregrounded in the discussion. We suggest that future research should focus first on the content of these goals, especially on the content of societal and commercial goals and whether and how they can be combined in differing contexts.
