Abstract
The present work deepens the place of affectivities in social movements, specifically in the case of Comisión Defensora de los Ríos Convento y Sonador which opposed to the building of two hydroelectric projects in these same rivers. In this way, an approach to the psychosocial effects in the communities that organized themselves against these projects is carried out. In order to accomplish these objectives, interviews and a participatory workshop took place with the members of the Comisión. It can be seen how the relationship they keep with the rivers is the affective core of their defense. Besides, among the psychosocial consequences, conflict generation and disruption of community relations were identified.
Key words: affectivities; social movements; hydroelectric projects; community relations
