title: Activist trust: the diffusion of green expertise in a Brazilian landscape.
abstract: MST (Movimento Sem Terra/Landless People's Movement) is the largest rural movement of Latin America. Since the late 1990s, it has taken part in the diffusion of expertise about biodiversity conservation. Using an ethnographic approach, this paper investigates sources and roles of trust within this process. How does trust work when experts and laypeople belong to the same movement? The paper uses and critically discusses the works of Brian Wynne and the Actor Network Theory. It describes the particular ways in which the building of trust takes place within the intimate networks of MST. As ecological expertise becomes a central element within MST's project of liberation, the sources of trust are both affective and effective. Interests, social recognition and identity are intertwined. In the conclusion, I propose the concept of activist trust.
