<dcterms:abstract xml:lang="fr">L’objectif principal de cette thèse est d’examiner les facteurs sociaux qui influencent l’adoption de l’agriculture biologique. Nous avons dérivé et répondu aux questions centrales des chapitres pour réaliser cet objectif. Chaque chapitre analyse un groupe de facteurs (normes sociales, formation et conseils techniques, contrat de vente, certification et traçabilité, voisins et leadership; leadership et partage d’information). Une analyse économique différente est appliquée : régression méta-analyse ; expérience sur le terrain avec expérience de choix discret ; modèle théorique ; et expérimentation sur le terrain avec jeu de négociation de Nash. Cette thèse peut servir de référence pour la conception et la mise en œuvre d’expériences contextualisées de laboratoire sur le terrain avec des agriculteurs. Il s’agit de l’une des premières études à proposer un modèle théorique pour des expériences en laboratoire sur le terrain utilisant la négociation de Nash dans l’agriculture biologique.</dcterms:abstract>

We derived and answered the central questions in the abovementioned chapters to realize this objective. Each chapter analyzed a group of factors (social norms; the training and technical advice, sales contract, certification and traceability, neighbors, and leadership; leadership and information sharing) comprehensively and applied respectively a different economic analysis to answer its question: meta-analysis regression; field experiment with discrete choice experience; theoretical model; and field experiment with Nash-bargaining game. This thesis may be a reference for designing and implementing contextualized lab-in-field experiments with farmers. It is one of the first studies to propose a theoretical building for lab-in-field experiments using Nash bargaining in organic agriculture.</dcterms:abstract>
