Consumption,Environmental Sustainability and Human Geography in Australia: a Missing Research Agenda?

‘Consumption’ is a central concept in the global environmental sustainability agenda. However, one important argument from Agenda 21 — that all social actors must now practise ‘sustainable consumption’— has been publicly and politically marginalised in high‐income countries such as Australia. Geographers potentially have a role in bringing consumption back onto the agenda by constructing a critical geography of consumption. Such research can help understand how the contextual use of natural resources is perceived and practised, and how consumption helps to shape contemporary social relations. This body of knowledge is vital for building sustainable development into everyday lives. Yet a focus on urban consumption perceptions and practices appears somewhat lacking in Australian geography. Ways forward can be drawn from international geography, such as in the United Kingdom where a substantial body of work has drawn a complex picture of contemporary consumption and environmental understanding. It has also challenged prevailing ‘ecological modernisation’ policy approaches, which ignore consumption's cultural facets. In sum, considering consumption in Australia can offer insights into cultural practices expressed through consumption; can challenge and add to European geographical literatures, and can also contribute to sustainability debates by offering alternatives to currently ineffective policy discourses.     

Intra‐individual variation in stable carbon (δ13C) and nitrogen (δ15N) isotopes in mandibles of modern caribou of Qamanirjuaq (Rangifer tarandus groenlandicus) and Banks Island (Rangifer tarandus pearyi): Implications for tracing seasonal and temporal changes in diet

Intra‐individual variations in carbon (δ¹³C) and nitrogen (δ¹⁵N) isotope measurements of dentine collagen in ungulate teeth can be related to diet and environmental changes at different periods during the life of the animal. A protocol of serial sampling of first, second and third molar roots was applied to modern caribou (17–27 months old) of the Qamanirjuaq herd (Rangifer tarandus groenlandicus), Canada. Based on a previous study, we predicted that M2 would reflect winter, M3 summer and M1 a complete year in terms of the isotopic record. Relatively high δ¹⁵N values (ca. 6 to 8‰), previously attributed to winter stress, were found in different molars of different specimens, reflecting a period of growth between April 1966 to April 1967. Previous results on other teeth from the same population confirmed that a high δ¹⁵N_coll value signal corresponded to the winter of 1966/67. This temporary increase in δ¹⁵N value was probably linked to diet and/or environmental change. Collagen from M1 reflects the first winter whereas M2 and M3 reflect the second winter of life of young caribou. A longer time record including summer is represented by the bone collagen of the mandible. Results obtained on molar roots and mandible bone of the modern caribou of Banks Island herd (Rangifer tarandus pearyi) confirmed this seasonal record. Such collagen isotopic analysis on M1, M2 and M3 roots and jawbone can be applied to reindeer found in archaeological sites. Mandibles retaining deciduous premolars are preferable to avoid the possible loss of the winter tooth signal observed in animals older than 2 years. Copyright © 2010 John Wiley & Sons, Ltd.     

Environmental responsibility and the possibilities of pragmatist-orientated research

Human geographers have explored at some length the discourses and subject positions implicated in the recent rise of ‘environmental responsibility’. Assigning it either as an individual disposition enacted in various spaces, a performative ‘othering’ tool, and/or a form of ecological governmentality, these debates have said little about the role of research and researchers in encouraging environmental responsibility. Utilising arguments from William James’ ‘radical empiricism’, I argue that exploring practices through a pragmatist lens enables a tentative re-envisioning of environmental responsibility. Re-visiting my doctoral research into the household-level adoption of sustainable consumption practices, I claim environmental responsibility as an ethical experience felt at the moments when practices are reconsidered. Here, my presence played a vital role in this social experimentation, which, as pragmatists argue, is the fundamental basis of positive social change.     

The ‘R-Word’ and ‘E-Word’ Definitional Controversies: A Dialogue with My Five Interlocutors

In this piece, I reply to the principal criticisms made by my five interlocutors regarding my conception of Eurocentrism. This entails two key aspects with the first section discussing the ‘E-Word definitional controversy’, where I argue, in the light of the forum, that there are various competing definitions of Eurocentrism in postcolonialism which yield commensurable competing non-Eurocentric antidotes. While I defend my own position, I am interested in revealing this complex picture because it has not been brought to light before and I urge postcolonialists to debate these different conceptions. The second section considers the ‘R-Word controversy’ wherein my interlocutors want me to row back on my claim that post-1945 social science theory is founded on subliminal Eurocentric institutionalism rather than scientific racism or neo-racism. There I consider some of the issues that are stake while concluding that modern Eurocentrism is indeed embedded in racialised thought.     

Carbon isotope measurement techniques for bone collagen: Notes for the archaeologist

Stable carbon isotope analysis of archaeological human bone collagen is becoming increasingly useful in diet reconstructions. This paper describes, for archaeologists, the techniques that we have found useful in carrying out such analyses, and discusses the requirements for measurement accuracy and inter-laboratory calibration.
