The agroecological transition of farms requires an in-depth change in advisory approaches, placing the farmer at the centre of a co-innovation and adaptive management approach. In this context, the main objective of the OUTILLAGE project was to close the gap in operational resources to support these new approaches, by developing tools to support farmers in their system change. Led by Terres Inovia, the project brought together 22 partners for 4 years. It relied on three farmer networks (Berry network, VIVESCIAgrosol club, AGRO D'OC group) to produce three types of tools: (i) dashboards applied to obtaining a robust rapeseed and to the success of sunflower in conservation agriculture, (ii) a decision tree applied to the transition to conservation agriculture, (iii) observation methods to feed these different tools. In this article we also describe the diversity of approaches to advising/supporting farmers and therefore the diversity of expectations in terms of tools and their uses, highlighted during the project. Finally, we propose a framework to help with the construction and use of customised tools, to contribute to scale up these new approaches of innovation support.
