This contribution discusses two different but interlinked fields of research: political theories of sovereignty and citizenship, as well as conceptualizations of emerging alternative food movements. In drawing on James Tully’s practiced-based understanding of ‘diverse citizenship’, as well as on other selected theories of postmodern political thought, it focuses on the contested political nature of the food sovereignty movement, specifically with regard to the dynamics and actions that have brought it into being. In doing so, it conceives of citizenship as materializing on the basis of multi-faceted practices of ‘acting otherwise’, which stands in sharp contrast to a conceptualization of citizenship as an institutionalized status, as it is understood in the liberal tradition. In order to deepen and to sharpen this alternative approach, this contribution additionally draws on Theodore Schatzki’s practice theory, which, despite its rather apolitical character, makes it possible to conceive of political practices as emergent and situational phenomena that are closely connected to the quotidian practices of everyday life. The combination of these perspectives bears great potential for theoretical discussions on alternative food movements as well as for their empirical investigation, since it puts emphasis on the way how practitioners and advocates for food sovereignty disclose themselves in multifaceted struggles over the imposition and the challenging of the rules of social living together.
