| In the Camargue, rice and durum wheat are associated in rotations that have an ambivalent ecological impact: on the one hand, these two crops contribute to the preservation of the surrounding ecosystem, while on the other hand, when cropped intensively, they can threaten the ecological equilibrium of this protected area. In this context, organic agriculture would seem to be an alternative adopted by a certain number of producers and processors. However, the pioneers of this practice encounter numerous problems, both agronomic and economic. The study presented here aims: to construct a pluridisciplinary approach to analyse the conditions of the development of organic cereal cultivation in the Camargue: to identify the principal factors that limit the... |

| La céréaliculture biologique apparait comme une alternative aux modes de production conventionnels, pour un nombre croissant d'agriculteurs de Camargue. Le programme CEBIOCA cherche à appuyer le développement de ce prototype d'agriculture en favorisant l'élaboration de pratiques agricoles pertinentes, la production de matériel végétal adapté et la mesure des impacts de la conversion à l'AB. Un groupe de travail interdisciplinaire, associant génétique, agronomie, malherbologie, écologie et sociologie s'est constitué à l'occasion de la réponse à l'appel d'offre CIAB et au cours de la première phase de fonctionnemet qui est présenté ici. Malgré certaines lacunes ou faiblesses dans la construction interdiciplinaire, les résultats font entrevoir des... |

| We are presenting an analysis of the obstacles and levers for the development of organic cropping systems in Camargue, documented with a multicriteria analysis of scenarios of organic farming (OF) development. This communication is built using results from on-farm agronomic monitoring, stakeholders and farmers’ interviews and the use of models for integrated assessment of scenarios. At the farm level, the obstacles are related to identification of profitable cropping systems and rotations that include enough rice, conversion being therefore risky as impacting financial management and requiring a labour reorganisation. At the regional level, the constraints are related to the absence of advisory services for technical issues, and to the lack of coordination... |

| To face and better manage the development of new varieties in a society calling for more and more transparency, the French National Research Institute (INRA) has get involved in an ambitious reflexive program about the question of "impacts, acceptability and management of varietal innovations" engaging all its thematic research departments. New collaboration between social and technical sciences are promoted to produce, from exemplary case studies, generic concepts and tools to assess the different types of impact of a new variety. Breeding and management of new genetic materials adapted to organic farming conditions constitute an appropriate theme to develop such an integrated process. A pluridisciplinary research team, associating plant breeders, soil... |

| La vitesse de minéralisation d’un engrais organique commercial a été évaluée durant trois années dans une rizière biologique en Camargue (France). L’effet de différentes doses d’engrais apportées à différentes périodes a été testé. En conditions inondées, l’engrais organique minéralise rapidement. Sur la base de ce résultat, nous montrons qu’une adaptation des pratiques de fertilisation organique, inspirée de celles appliquées pour des engrais minéraux, permet une meilleure valorisation des engrais organiques, découlant sur une meilleure rentabilité. |
