ABSTRACT
This chapter reflects on the materials I am using to explore how the emergence of environmentalism during the 1970s informed spatial ideas and practices in a context dominated by the awareness of the scarcity of resources and the vulnerability of the planet. The twofold condition of the movement which emerged at the same time as an activist movement and within the institutional sphere aims to open the scope of the research sources. Besides archive material, canonical texts and drawings, it examines how alternative material such as fanzines, pamphlets or documented critical actions are pivotal sources to look at; and how the contribution of activists, dilettantes and other amateur actors must be considered as central figures in order to craft the counternarratives on environmentalist spatial practices. Following the Foucauldian concept of transgression, the chapter conceptualizes these contributions as transgressive practices. That is, pointing out the anticipatory condition of their ideas and strategies. The chapter finally reflects on the importance of confronting mainstream historiography with narratives crafted from alternative voices and sources, in order to produce a more polyvocal planning history.
