Techno-scientific modes of seeing, classifying, and measuring the earth are reformulating the ways in which territorial disputes are currently played out. Due to the mobilisation of science by capital we today inhabit an earth that is being reduced to discrete components. The extreme case of this condition is what I will call the underground frontier: The underground is no longer simply the space where resources are located, but has itself been converted into a resource. However, if one wishes to investigate the processes by which the underground has been converted into a resource and the role of technoscience in these processes, one should be prepared to investigate the spatial and political assemblages of which technoscience is part: how it is mobilised, used, financed, and how it becomes part of wider political, cultural or legal claims.
