This article presents a psychosocial intervention project which was developed in order to support Colombian peasant families who had been violently displaced from their farms and villages by civil war in Colombia. Additionally, a considerable number of families had suffered the loss of one or various members who died because of the war. Dropped into an unknown social environment, separated from their traditional economic base and overwhelmed by the trauma suffered from war, their present and future lives are uncertain. With the alliance between displaced families, governmental institutions, non governmental organizations and academics a social intervention project was created in order to attend different aspects (economic, social, cultural and psychological) of displacement. This article describes the psychosocial intervention strategies in order to rehabilitate individuals and families and to restore their capacity of action. The intervention project was based on the resilience approach: it focused on the ability of individuals and groups to cope with extremely critical conditions and to secure their survivorship.
