Resource depression, climate change, and mountain sheep in the eastern Great Basin of western North America

Strontium, oxygen, and carbon stable isotope analysis may be used in conjunction with archaeofaunal data to identify resource depression by demonstrating that prey were obtained from more distant locations. We use fauna from Five Finger Ridge, a Fremont site in central Utah, to demonstrate that relative abundances of mountain sheep (Ovis canadensis) declined during a period of increased summer precipitation. Strontium ratio values from this period indicate that sheep were acquired from different locations than the preceding period. Specimens from this period also show a moderate increase in carbon ratio values, suggesting that mountain sheep were acquired from higher altitudes. Oxygen isotopes do not vary between temporal periods, possibly the result of the countering effects of higher oxygen isotope values associated with increased summer temperatures and lower oxygen isotope values present at higher elevations. Collectively, these data support that there were localized population declines of mountain sheep that may be related to either climatic changes or hunting pressure.     

Geographic film as public research: re-visualizing/vitalizing a terraced landscape in the Italian Alps (Piccola terra/Small land, 2012)

This article describes an experience of geographic filmmaking carried out within a long-term research process (2000–2012) involving the terraced landscape of the Brenta Valley in the Italian Alps. The documentary Piccola terra [Small land] (2012) was co-produced by geographers and professional directors. Engaging in the recent debate on filmic geographies, the aim of this article is to discuss and show what makes a film ‘geographic’. The geographer authored a filmic interpretation of landscape which is spatially and temporally complex, open and mobile, anchored to material features and to personal stories and socio-economic contexts. Produced to support a campaign for the adoption of abandoned terraces by ‘new farmers’, the documentary Piccola terra serves as a means to engage society and produce landscape change. Geographic filmmaking as an action-, public- and social-oriented activity is discussed with reference to the so-called ‘impact agenda’. We propose a style of active engagement through filmmaking which is workable, rather than critical. In order to avoid purely auto-reflective, auto-referential academic speculation on doing filmic and public geographies, this paper, which ideally is read along with viewing of the documentary, materially enters the researched/filmed landscape, developing into a supplementary tool for the international dissemination of Piccola terra.     

“Whiteness” and natural resource management: let's talk about race baby,let's talk about sovereignty!

Issues of race and sovereignty are embedded in every cross‐cultural collaboration in natural resource management (NRM). This article aims to bring these issues to the forefront by incorporating the term whiteness. Whiteness enables a critique of the privileging of Western sovereignty and the so‐called objective and universal value of Western science. By reversing the gaze away from the colonised Other and onto systems descended from colonial authority and its inheritors, whiteness identifies how race privilege works. A critical whiteness lens provides an analytical and practical tool for decolonising NRM. We provide a case study of the South Australian Department of Environment and Water to consider how NRM professionals reproduce and deconstruct whiteness in nuanced ways, where (a) participants are defeated by Western sovereignty when whiteness is seen as normal or as the only way; (b) the privilege of Western sovereignty begins to be unsettled; and (c) the gaze is reversed. Thus,Western sovereignty is problematized, and solutions to persistent problems are found in collaboration. We argue that reversing the gaze is a process that opens spaces to co‐develop context specific solutions with Indigenous nations that decolonise cross‐cultural engagement in NRM and respect Indigenous sovereignty.

"FIRST FEED THE FACE": ENVIRONMENTAL JUSTICE AND COMMUNITY FOOD SECURITY

Environmental justice and community food security represent parallel though largely separate movements whose linkage would help establish a new community development, environmental, and empowerment-based discourse. Environmental justice has been limited by its risk discrimination focus, even as environmental justice organizations have shifted to a broader social justice orientation, eclipsing their earlier environmental focus. Community food security advocacy, while offering a concrete example of linked agendas and constituencies, has yet to effectively outreach to environmental justice groups. Coalition building efforts, such as the Community Food Security Empowerment Act, presents that opportunity.     

Identifying biomolecular origins of solid organic residues preserved in Iron Age Pottery using DTMS and MVA

The chemical characterisation of solid organic residues found in ceramic vessels, can provide archaeologists with valuable information about ancient diets. Although several selective analytical techniques have been applied to the analysis of specific classes of compounds, such as extractable lipids, waxes, terpenoids and protein fragments, a non-selective analytical technique is required to characterise and categorise complete solid organic residues. In this study, Direct Temperature-resolved Mass Spectrometry (DTMS) is used for the characterisation of 34 solid residues situated on vessels recovered from an indigenous settlement from the Roman period at Uitgeest – Groot Dorregeest (The Netherlands). Sample preparation is limited to grinding very small samples (5–10 μg) and suspending them in water. DTMS analysis of aliquots (1–2 μL) of this suspension gave information about a broad range of organic compounds, such as lipids, polynuclear aromatic hydrocarbons, markers for residual proteins and polysaccharides, and for newly formed complex condensed polymers. Multivariate analysis of the DTMS spectra identified five different chemotypes: groups of residues with comparable chemical characteristics. The biomolecular origin of each of these chemotypes is identified by comparison with experimentally charred reference materials. The chemotypes A₁ and A₂ consist of charred residues identified as starch-rich foods (mixed with animal or plant products), chemotype C consists of protein-rich charred animal products without starch, chemotype B contains smoke condensates from wood fires, and chemotype D consists of special protein-rich and lipid-free foods or non-food products.
