This paper presents the conceptual and methodological perspective of participatory action research with an interdisciplinary approach. Specifically, thisresearch examines different dimensions that condition the access to water for farming families in the Pampa region. Together with famers and extension workers, we defined the problems, considering that water asmediator of social relations among different actors involved – resource appropriation for irrigation and agricultural production and other sectors’ productions, family consumption and sewage-. In the last sections of the document, the research team presents observations, analysis and reflections on the progress of field work we have done so far.
