Vista Alegre is a municipality in the province of Neuquén, Argentina. Situated in a region traditionally known for its fruticulture economy, Vista Alegre has recently been identified as a potential location for fracking, a development that has resulted in widespread opposition among its inhabitants. The fight against fracking in Vista Alegre has followed a number of channels, from road blockades to art festivals and a legal challenge to the municipality. This paper analyses the conflict focusing on the forms of community art and media employed by the local assembly against fracking to widen and sustain participation in the struggle, and the role that these media have in mediating collective identity processes in the fight against fracking. Building on the concept of mediated identities (Fornäs and Xinaris, 2013), I look at these community art and media practices as dialogical (Kester, 2004). I propose that activities such as art festivals, mural painting and open radios contribute to collective identity processes through three mediating tactics: participation, knowledge sharing and the event modality. I conclude by arguing that these forms of community arts and media can be seen as a productive output of the conflict (Merlinsky, 2015), as they become crucial practices of cultural resistance.
