Geographical research on lithium and other renewable energy materials explores the geopolitical dimensions of resource supply and the 'new geographies' associated with an expanding resource frontier. The material characteristics and environmental conditions of lithium production, however, are largely overlooked in this perspective. In the context of a global speculative boom for lithium linked to its growing role in energy storage, this paper adopts a grounded, exploratory approach to investigate the dynamics of production and resource management at one of the world's most significant sources of lithium: the brine deposits of the Atacama Salt Flat/Salar de Atacama in northern Chile. We show how lithium production from brine has a distinctive 'eco-regulatory' character as it involves managing a series of hydrogeological conditions and physical processes that are largely external to capital. The paper highlights the infrastructures (pumps, pipes, ponds) associated with the harvesting of lithium from brine and examines how production on the salar generates a series of ecological contradictions (notably around water depletion) with potential to disrupt accumulation. We also examine the multiple flexibilities afforded by the eco- regulatory character of production, and show how these enable lithium producers to adapt fixed infrastructures to dynamic political economic conditions. By focusing on both contradictions and flexibilities of lithium production, the paper draws attention to trajectories of capitalisation in the lithium value chain and their environmental consequences; and considers the political-economic incentives shaping further capitalisation. The paper concludes by considering the implications of this exploratory case study for critical resource geography.

This paper makes a case for examining energy transition as a geographical process, involving the reconfiguration of current patterns and scales of economic and social activity. The paper draws on a seminar series on the 'Geographies of Energy Transition: security, climate, governance' hosted by the authors between 2009 and 2011, which initiated a dialogue between energy studies and the discipline of human geography. Focussing on the UK Government's policy for a low carbon transition, the paper provides a conceptual language with which to describe and assess the geographical implications of a transition towards low carbon energy. Six concepts are introduced and explained: location, landscape, territoriality, spatial differentiation, scaling, and spatial embeddedness. Examples illustrate how the geographies of a future low-carbon economy are not yet determined and that a range of divergent – and contending – potential geographical futures are in play. More attention to the spaces and places that transition to a low-carbon economy will produce can help better understand what living in a low-carbon economy will be like. It also provides a way to help evaluate the choices and pathways available.

Research in political ecology and agrarian political economy has shown how commodity frontiers are constituted through the appropriation and transformation of nature. This work identifies two broad processes of socio-metabolism associated with commodity frontiers: the spatial extension of nature-appropriation, via expanding territorial claims to the control and use of natural resources and associated acts of dispossession (commodity-widening); and the intensification of appropriation at existing sites, through socio-technical innovation and the growing capitalisation of production (commodity-deepening). While sympathetic, we have reservations about reducing frontier metabolism to either one or the other of these processes. We argue for more grounded examinations of how non-human nature is actively reconstituted at commodity frontiers, attuned to the diverse and specific ways in which socio-ecological processes are harnessed to dynamics of accumulation. To achieve this, we compare strategies of appropriation in three sectors often associated with the commodity frontier: gold mining, tree plantations, and intensive aquaculture. In doing so, we bring research on capitalism as an ecological regime into conversation with work on the industrial dynamics of 'nature-facing' sectors. By harnessing the analytical categories of time, space and form adopted by research on industrial dynamics, we (i) show how strategies of commodity-widening and deepening are shaped in significant ways by the biophysical characteristics of these sectors; and (ii) identify a third strategy, beyond commodity-widening and deepening, that involves the active reconstitution of socio-ecological systems - we term this 'commodity-transformation.'
