Mastering quality and solidarity in producer-groups. The relevance of innovations in the Corsican livestock farming sector. In Corsica, livestock farmers frequently respond to growing constraints by increasingly integrating livestock production activities at individual farm level, i.e. processing their raw products (park meat, ewe and goat milk) and selling their production themselves. This trend towards individualistic production, processing and marketing brings into question the relevance of technical innovations. The needs of the farmers must be analysed to help them better master their farming activity and ultimately develop a solidarity between themselves. In fact, reinforcing the present logic of individual producers can proue contrary ta their collective organisation. Technical and social relevance do not seem to fit one another entirely. The concept of "organizing innovation" is proposed to account for the conditions of social control of innovations and the regulating capacity of a "collective actor". The autonomy of the individual {armer places the notion of quality into an informational box of his decision-making system, thereby reinforcing self-reference. As a result, the technical relevance of an innovation for the {armer is steered exclusively by satisfaction. Putting the "{armer first" may reduce the possibility of innovating to his own individual management abilities. On the contrary, collective self-organisation of producers places quality in relation ta productive segmentation and within an operational link between members. Ta achieve collective satisfaction, organized producers will stimulate the "intelligence" of their common decision-making system. This is based essentially on learning through building this collective satisfaction. "Organising innovations" are innovations that will induce this process of self-organisation and by this means, solidarisation of the farmers. This constructivist approach may, under certain conditions to be further defined, confer to the notion of quality the function of an organising lever in the development process.
