Using the laying hen sector as a case study, we aim to demonstrate the potential for practice-driven innovation networks, supported by existing science and market-driven actors, to develop practical cost-effective solutions to sustainability challenges (objective 1). Multi-stakeholder networks will develop technical innovations to injurious pecking and the management of end-of-lay hens concerns based on practice, economics and scientific information (objective 2). A generic “support package” of communication web based tools, facilitation guides and on-line training programmes, designed to help science and market- driven actors, will then be available to support practice-driven innovation networks in other livestock sectors (objective 3). Finally we will develop policy recommendations that help realize the full potential of practice-driven innovation through multi stakeholder networks in livestock sectors (objective 4). This project will tackle four challenges associated with the need for grass-root innovation highlighted in the Horizon 2020 call; 1) legitimacy by robust practical and financial evaluation, 2) accessibility by communication between producers and existing innovation support actors, 3) connectivity by an industry-led dissemination strategy ensuring information about innovations are widely spread using existing communication tools and finally 4) sufficient resource by production of a support package and policy recommendations that facilitate better interaction of science-driven and practice-driven innovation. The success of this approach to the laying hen sector and other sectors will be evaluated by the ability of the network to encourage practice-led innovation, check the effectiveness of the innovation, ensure optimum use of scientific information, provide a route for traditional knowledge transfer when required, disseminate results of innovation to others and ensure that policy is informed by practice-led solutions.
