Abstract EN:

Burkinabe's agriculture is characterized by the weakness of its ressources and the low technical nature of its farmers. Faced with the requirements of food self-sufficiency and competitiveness, it tries to respond to requests related to new issues of social and economic change. Institutional, political and technical actions had an impact on rural development but production systems are vulnerable and the conflicts that arise from these quests for survival or better conditions are hardly a definitive solution, as at the "witness box", a key player is missing : the State. The obstacles to the adoption of the technologies proposed by the Agricultural Research often expressed by a certain lack. Given the vulnerability of production systems, several approaches have been developed. These approaches attempts to integrate the specific interest and motivations of the different stakeholders but they are often at odds with the social demands and the peasant practices. So, there are two systems interpretation of development (one of the panellists and the peasants), which are parallel, sometimes competing. We conclude then that a sustainable articulation between the practices of development actors and those of peasants requires a setting up of new intervention methods in rural areas. This thesis attempts to assess the factors influencing the relationship between the practices of including agronomic research and the peasants practices.
