The Societal Challenges addressed by European Union (EU) strategies such as the Green Deal and Farm-to-Form require innovative solutions in agriculture, forestry and rural areas. The Multi-Actor-Approach (MAA) is a promising instrument to speed up innovation. However, the H2020 RIA LIAISON (2018-2022) has identified some deficits and inconsistencies in the interpretation of the MAA by both current and potential MA consortia and Member States’ (MS) authorities. PREMIERE will therefore foster the development of sound, coherent and well-prepared MA projects in two ways. Firstly, it will contribute to the building of project consortia that make best use of the complementary knowledge of their members during proposal writing, project activities and beyond, in particular by improving the connection between Horizon Europe (HE) MA projects and Operational Groups (OG). Secondly, through insights and tools, it will support the implementation of innovative governance and sound decision making in policy and administration for the green transition. By using the results from LIAISON and capturing ‘grass roots’ ideas from project participants, policy makers and executive agencies through stakeholder dialogue across all 27 EU MS (including with the SCAR AKIS SWG, National Contact Points and other relevant HE projects), PREMIERE will develop tools as well as training and networking events for capacity development. These will include a Serious Game, an Online Academy and a MOOC. The project will test out the effect of providing seed funding to at least eight MA organisations (mainly OGs) and prepare a handbook of good practices. This user-focused workplan, with its open science outputs, will lead to more effective EU and national AKIS. It will be implemented by a very experienced, competent and genuinely MA consortium of policy makers, executive agencies, advisors for co-innovation partnerships, AKIS actors and/or and current and potential MA project partners.
