Given the huge challenges agriculture has to face, both in Northern and Southern countries, a radical change in farming practices towards agroecology is required. Most scientific literature on the design of new farming systems describes de novo approaches, which focus on disruption and novelty, without any concern for the way to move from the current system to the innovative one. In this study, we highlight, for the first time, the particular traits of what we will call the step-by-step design approach.

Experimentation conducted by or with agronomists on farmers' farms is not a fixed methodology, and even less a one-size-fits-all one. There is a wide diversity of ways of implementing experimental protocols, carrying out monitoring and evaluation, and making use of the results. This article proposes an analysis of this diversity via a review of the scientific literature and the identification of 7 types of on-farm experimentation practices.

This paper focuses on characterising the variability of camelina yield and quality gains under different pedoclimatic conditions in northern France and identifying factors explaining this variability.

Combining the richness of a participatory approach involving all the stakeholders of a territory with the power of simulation tools: this is the originality of the approach that was implemented on the scale of the "Langrois plateau", in order to assess its potential for the reintroduction of legumes.

The agro-ecological transition requires a profound and systemic transformation of agricultural practices. Among the candidate innovations, multi-species associations are known to reduce the environmental impacts of agriculture, while maintaining or even increasing yields. Although they are not widely used, some farmers nevertheless cultivate them with satisfaction.
