EIP-AGRI Operational Groups are innovative projects that aim to find practical solutions to problems or opportunities which European farmers and foresters are currently facing. More than 3200 are planned by national and regional Rural Development Programmes for the period 2014-2020. Operational Groups can benefit from networking and collaborating with organisations from outside their partnership and from other regions and countries, such as other Operational Groups, research projects, farmers’ organisations or local authorities and European knowledge networks. Whether it is meeting at events, exchanging knowledge on similar topics over the phone, hearing about personal experiences in running innovation projects, or setting up a more formal collaboration agreement, Operational Groups can reap the benefits of national or international collaboration in different ways. This brochure shows some examples of successful collaborations. It provides Operational Groups with inspiration and tools for further knowledge exchange within the EIP-AGRI network.
