Profit,reputation and ‘doing the right thing’: Convention theory and the problem of food waste in the UK retail sector

In 2014, Tesco – one of the world’s largest food retailers – revealed that it had generated almost 57,000 tonnes of food waste in its UK operations over the previous twelve-month period. This shocking statistic added to existing evidence of a significant environmental and social problem in the UK and across the world. This paper utilises convention theory to examine the role of major retailers in the context of this global problem and assesses their motivations for acting on food waste. Drawing on interviews with key stakeholders (including major retailers), the analysis investigates their main justifications for action on food waste. It finds that retailers mostly appealed to three conventions or ‘orders of worth’ (civic, market and opinion) and used these as a basis for their commitment to food waste reduction. We argue that the combination of these different justifications is feasible and necessary in the context of the retail sector but that they may also lead to some unintended consequences (in the retail sector and beyond). Crucially, we demonstrate how the dilution of civic justifications (by their financial and reputational counterparts) might produce negative outcomes and inaction as retailers attempt to adhere to the so-called ‘food waste hierarchy’. The paper highlights the continuing significance of convention theory as a framework for analysing possible responses to the social and environmental challenges confronting global agro-food systems.     

Quantitative risk assessment of slope hazards along a section of railway in the Canadian Cordillera—a methodology considering the uncertainty in the results

Railway alignments through the Canadian Cordillera are constantly exposed to slope instabilities. Proactive mitigation strategies have been in place for a few decades now, and instability record keeping has been recognized as an important aspect of them. Such a proactive strategy has enhanced the industry’s capacity to manage slope risks, and some sections have been recognized as critical due to the frequency of instabilities. At these locations, quantification of the risks becomes necessary. Risk analysis requires knowledge of some variables for which statistical data are scarce or not available, and elicitation of subjective probabilities is needed. A limitation of such approaches lies in the uncertainty associated to those elicited probabilities. In this paper, a quantitative risk analysis is presented for a section of railway across the Canadian Cordillera. The analysis focused on the risk to life of the freight train crews working along this section. Upper and lower bounds were elicited to cope with the uncertainties associated with this approach. A Monte Carlo simulation technique was then applied to obtain the probability distribution of the estimated risks. The risk probability distribution suggests that the risk to life of the crews is below previously published evaluation criteria and within acceptable levels. The risk assessment approach proposed focuses on providing a measure of the uncertainty associated with the estimated risk and is capable of handling distributions that cover more than two orders of magnitude.

Charting the emergence of a ‘knowing system’ for climate change adaptation in Australian regional natural resource management

Climate change increases the complexity and uncertainty of regional natural resource management (NRM), calling into question the appropriateness of linear knowledge-transfer approaches. In this paper we reflect on knowledge practices among a partnership of researchers and NRM planners, under a federal program of NRM investment intended to ‘deliver information’ to regional NRM planners to support planning for climate change. We unpack ‘container’ and ‘conduit’ metaphors of linear, one-way communication invoked by the starting conditions, and explore whether more relational ways of communicating were achieved. A key theme emerged early in the research that NRM planners felt overwhelmed by the sheer volume of information available and discouraged by the irrelevance of much of it to their climate change planning. Our research-practice collaboration unfolded in this context and through ongoing face-to-face and virtual engagement over a period of two years. The collaborative approach featured joint identification of priority activities, co-design of planning approaches, and the iterative co-development of an online ‘information portal’, which acted as a boundary object. We report the emergence of a ‘knowing system’, resulting from these efforts to foster relationships and co-produce boundary objects in a particular geographic context. Our findings highlight the potential benefits of investing in the capacity of researchers and NRM practitioners to engage in collaborative research partnerships premised on the emergence of knowing systems.     

From ‘criminals of the earth’ to ‘stewards of the environment’: The social and environmental justice of Fair Trade gold

The recent emergence of the Fairtrade certification of gold in Latin America and sub-Saharan Africa promises a radical new direction for the environmental governance of artisanal and small-scale mining (ASM). In doing so, it aims to tackle the longstanding environment and development challenges of the sector which mainstream policy has failed to alleviate. The move towards more responsible ASM practices is premised on the strategic deployment of a Fair Trade discourse that argues for its operators to be recognized not as criminals, but as valued and formalized parts of their broader economies. It is argued in this paper that this development intervention should be read within a social and environmental justice framework, one which directly answers the call from political geography for ‘compelling accounts’ of positive representations of the sector.Through a discourse analysis of 10 years of media reports, interviews and recorded life histories of key ASM and Fair Trade stakeholders in Tanzania, it shows how three strands of justice (conceptualized in terms of fairer distribution, procedure and recognition) are articulated by the Fair Trade gold movement and critically assesses the politics behind such a deliberate strategy. In particular, it argues that recognition is a key part of justice that has been underplayed by erstwhile analyses of Fair Trade. Through a case study of Tanzania, it is concluded that although significant progress has been made in terms of arguing for greater recognition for ASM operators, there remains a need to better link discourse with practice in establishing greater distributional justice.     

‘Marketing quality’ in the food sector: Towards a critical engagement with the ‘quality turn’ in wine

Our review explores the role of quality conventions that have emerged since the 'quality turn' in the food sector. By examining how the 'quality turn' contributes to transforming the wine sector, it asks whether the labeling systems seek to certify the quality of productive practices (informative function) or are intended to create imaginaries of quality as a differentiated business market strategy (symbolic function). After discussing relevant literature in geography and related fields, this review uses two emblematic examples from the wine sector to argue for the need to move beyond the marketing of quality to deepen the analysis and understanding of quality. This analytic insight questions the viability and usefulness of quality conventions aimed at differentiation, territorial development, with a focus on markets with high added value, and argues for the need to open new lines of research and policy in this sphere.     

Spatial variability of the Purbeck–Wight Fault Zone—a long-lived tectonic element in the southern UK

New seamless onshore to offshore bedrock (1:10 k scale) mapping for the Lyme Bay area is used to resolve the westward termination of the Purbeck–Wight Fault Zone (PWFZ) structure, comprising one of the most prominent, long-lived (Variscan–Cimmerian–Alpine) structural lineaments in the southern UK. The study area lies south of the Variscan Frontal Thrust and overlays the basement Variscide Rhenohercynian Zone, in a region of dominant E-W tectonic fabric and a secondary conjugate NW-SE/NE-SW fabric. The PWFZ comprises one of the E-W major structures, with a typical history including Permian to early Cretaceous growth movement (relating to basement Variscan Thrust reactivation) followed by significant Alpine (Helvetic) inversion. Previous interpretations of the PWFZ have been limited by the low resolution (1:250 k scale) of the available offshore BGS mapping, and our study fills this gap. We describe a significant change in structural style of the fault zone from east to west. In the Weymouth Bay area, previous studies demonstrate the development of focussed strain associated with the PWFZ, accompanied by distributed strain, N-S fault development, and potential basement uplift in its hangingwall. In the Lyme Bay area to the west, faulting is dominantly E-W, with N-S faulting absent. Comparison of the newly mapped faulting networks to gravity data suggests a spatial relationship between this faulting variation and basement variability and uplift.     

Becoming a young migrant or stayer seen through the lens of ‘householding’: Households ‘in flux’ and the intersection of relations of gender and seniority

This paper conceptualises migration and staying by young rural Lao in the empirical context of above replacement level fertility as manifestations of ‘householding’ that interacts with other dimensions of householding. Drawing on the framework of the inter-generational contract and by juxtaposing qualitative and quantitative data I show that becoming a young migrant and becoming or remaining a young stayer is shaped by young migrants’ situated agency.The second part of the paper departs from conventional household-based analyses and introduces the notion of ‘households in flux’. This highlights the dynamic interaction between changing external dynamics affecting rural households, and internal dynamics that constantly reconfigure the field of the household. These conceptual readjustments require going beyond inflexible notions of the household, the analytical disconnection between a focus on migrants and stayers in migration research, and static readings of relations of gender and generation. Furthermore, the paper argues that intra-household relations need to be appreciated as gendered relations of relative seniority which are in the process of householding constantly made and remade, among other things, by young dependents through ‘staying’ and ‘leaving’. These conceptual moves help explain the empirical puzzle of why in rural Lao households young women are both the ones most inclined to become a young migrant as well as most inclined to become or remain a young stayer.     

Speciation studies of arsenic in the environment and in human

Arsenic is the 20th most abundant element in the Earth crust. Humans are exposed to naturally occurring and anthropogenic sources of arsenic compounds in the environment. A wide variety of adverse health effects have been attributed to chronic exposure to high levels of arsenic. More than two-dozen arsenic compounds （species） are present in the environment and in biological systems. The various arsenic species have dramatically different behavior and toxicity. This presentation briefly describes arsenic speciation analysis, human exposure to and metabolism of arsenic species. Environmental issues on arsenic in Canada are briefly discussed. These include （1） the arsenic waste left from previous gold mining and smelting activities; （2） the domestic use of wood treated with chromated copper arsenate; and （3） use of well water as the source of drinking water by approximately one third of the Canadian population.     

Boundary management and the discursive sphere – Negotiating ‘realities’ in Khorezm,Uzbekistan

With independence in 1991, Uzbekistan, as most of Central Asia, entered into a phase of socio-economic transformation. In agriculture, this state-driven restructuring of the former system has concentrated on the ‘formal’ sphere of land and water governance.This paper assesses water management in Khorezm, Uzbekistan, taking a social constructivist and boundary work-inspired perspective. Several limitations to effective water management in Khorezm exist. We argue that three types of practices are widely employed to manage these and assure water access: formal, strategic, and discursive practices. The discrepancy between the formal water management institutions, manifested and regulated through formal practices and the informal, widely pursued through strategic practices and acts of deviation, is overcome through discursive practices. Verbal references to formal institutions therefore hamper the formalizing of informal practices. The institutionalized employment of all three types of practices fosters the production and reproduction of boundaries demarcating two, largely separate, spheres of reality in Khorezm’s water management. Consequently, a high degree of resistance to the integration of informal water management realities into the formal regulatory environment prevails, preventing mutual learning and thus the locally informed restructuring towards more efficient and sustainable water management in Khorezm.

Geological evolution of the Hampshire Basin (southern England) during a global climate transition from ‘hothouse’ to ‘coolhouse’ in the Palaeogene

Palaeogene sediments of the Hampshire Basin were a sensitive recorder of fluctuations in climate and eustatic sea level as Earth's climate transitioned from the global early Eocene ‘hothouse’ to the early Oligocene ‘coolhouse’, accompanied by the first permanent continent-scale glaciation of Antarctica at the Eocene/Oligocene boundary. A study of the Palaeogene sediments of the Hampshire Basin is not only interesting from a palaeoclimate perspective, but the marine middle Eocene formations are renowned for containing some of the most abundant and diverse Palaeogene fossil assemblages in the world. In this article, I take you on a tour of the geological evolution of the Hampshire Basin from the end of the Paleocene through to the Pleistocene. I highlight some of the best exposures where sediments can be studied at outcrop and representative fossil assemblages can be collected, along with the economic and archaeological significance of these Palaeogene sediments.

Natural salinity sources in the groundwaters of Jordan—Importance of sustainable aquifer management

In recent years, voices in Jordan became lauder to exploit the fresh to brackish deep groundwater overlain by fresh groundwater bodies. In this article the implications of such a policy on the existing fresh water bodies are worked out through studying the sources of salinity in the different aquifer systems and the potentials of salinity mobilization by artificial changes in the hydrodynamic regimes. It is concluded that extracting the groundwater of deep aquifers overlain by fresh water bodies, whether the deep groundwater is fresh to brackish, brackish or salty, is equivalent to extracting groundwater from the overlying fresh groundwater bodies because of the hydraulic connections of the deep and the shallow aquifers’ groundwaters. The consequences are even more complicated and severe because exploiting the deep groundwater containing brackish or salty water will lead to refilling by fresh groundwater leaking from the overlying aquifers. The leaking water becomes salinized as soon as it enters the pore spaces of the emptied deep aquifer matrix and by mixing with the deep aquifer brackish or saline groundwater. Therefore, the move to exploit the deep groundwater is misleading and damaging the aquifers and is unjust to future generation's rights in the natural wealth of Jordan or any other country with similar aquifers’ set-up. In addition, desalination produces brines with high salinity which cannot easily be discharged in the highlands of Jordan (with only very limited access to the open sea) because they will on the long term percolate down into fresh water aquifers.     

The ethnographic spectacle of the ‘other’ Filipinos in early cinema

My paper aims to ask what space characterizes the various constructs of orientalism and othering in the early short films of Thomas Edison. Using Lefebvre’s concept that social space “subsumes things produced, and encompasses their interrelationships in their coexistence and simultaneity” in these early shorts, I will look at three Biograph actualities found at the Library of Congress-American Memory page to show how space is manifested and negotiated onscreen. I will examine Edison’s “Filipinos Retreat From Trenches”, “Capture of Trenches at Candaba” and “U.S. Troops and Red Cross in the Trenches Before Caloocan” which were all released in 1899. These reenacted short films were shot during the tumultuous years of the Spanish-American War. In the Biograph shorts, the privileged positions of both Spanish and American forces in relation to the annexation of a foreign land in world history books is indicative of the tendency to de-emphasize the contribution of the native population in the war. Manthia Diawara has said that “space is related to power and powerlessness, insofar as those who occupy the center of the screen are usually more powerful than those in the background or completely absent from the screen.” The spatial hierarchies and spatially situated images in Edison’s short films show how historically configured power relations encrypted oppression to its external “others” through the cinematic apparatus.
