From the Publisher. The journal Ground Up examines the impact of recent radical economic, political, and ecological shifts in the landscape. Previous models of prediction, projection, and simulacra are now obsolete, demanding new conceptual and spatial frameworks. The freefall of the economy leaves vacant space and spurs inventive reclamation through collective action. Drastic environmental transformation forces new paradigms of building, thinking, and living. What will be the character of space that emerges from this instability? How can design tactics initiate succession of under-used space? How do we represent process and temporality over traditional determinism? How long is temporary? Facing uncertainty in the landscape, how do we adjust our way of thinking to move past merely physical proposals to more open-ended operational strategies?
