This article analyses security discourses that are beginning to self-consciously take on board the shift towards the Anthropocene. It first sets out the developing episteme of the Anthropocene, highlighting the limits of instrumentalist cause-and-effect approaches to security, which are increasingly becoming displaced by discursive framings of securing as a process generated through new forms of mediation and agency and capable of grasping interrelations in a fluid context. This approach is the methodology of hacking: creatively composing and repurposing already existing forms of agency. It elaborates on hacking as a set of experimental practices and imaginaries of securing the Anthropocene, using as a case study the field of digital policy activism with a focus on community empowerment through social-technical assemblages being developed and applied in the City of the Anthropocene': Jakarta, Indonesia. The article concludes that policy interventions today cannot readily be grasped in modernist frameworks of problem solving' but should be seen more in terms of evolving and adaptive life hacks'.
