Spatializing Commodity Chains
Progress in Human Geography 23,3 (1999) pp. 401–420 Spatializing commodity chains Deborah Leslie1 and Suzanne Reimer2 1Department of Geography, Brock University, St Catharines, Ontario L2S 3A1, Canada 2Department of Geography, University of Hull, Hull HU6 7RX, UK Abstract: There has been a growing interest in connecting production and consumption through the study of commodity chains. We identify three distinct approaches to the chain and review debates concerning the merits of a ‘vertical’ rather than a ‘horizontal’ approach. Drawing upon the example of the home furnishings commodity chain, the article highlights the importance of including horizontal factors such as gender and place alongside vertical chains. We consider geographical contingencies which underpin commodity chain dynamics, the role of space in mediating relationships across the chain and the spatialities of different products. Key words: commodity chains, consumer culture, gender, home furnishings industry, space. I Introduction The topic of consumption has begun to receive considerable attention within geography. Rather than suggesting that cultural processes are simply reflective of economic or political factors, recent discussions have begun to emphasize the constitu- tive nature of culture within society (Crang, 1997; du Gay et al., 1997: 2) and to underscore the centrality of consumer cultures to social life (Lury, 1996; Slater, 1997). This ‘turn’ to consumption should not be taken to suggest that the phenomenon is purely contemporary. Rather, commodity cultures are central features of modernity itself (Slater, 1997). None the less, it is only recently that geographers and other social scientists have begun to rethink creatively the implications of consumption for economics and politics (Miller, 1995: 1; 1998). -

Changing European retail landscapes: New trends and challenges Josef KUNC a *, František KRIŽAN b Abstract During the second half of the 20th century, consumption patterns in the developed market economies have stabilised, while in the transition/EU-accession countries these patterns were accepted with unusual speed and dynamics. Differences, changes and current trends in Western Europe and post-socialist countries in the quantity and concentration of retailing activities have been minimised, whereas some distinctions in the quality of retail environments have remained. Changes have occurred in buying habits, shopping behaviour and consumer preferences basically for all population groups across the generations. This article is a theoretical and conceptual introduction to a Special Issue of the Moravian Geographical Reports (Volume 26, No. 3) on “The contemporary retail environment: shopping behaviour, consumers’ preferences, retailing and geomarketing”. The basic features which have occurred in European retailing environments are presented, together with a comparison (and confrontation) between Western and Eastern Europe. The multidisciplinary nature of retailing opens the discussion not only from a geographical perspective but also from the point of view of other social science disciplines that naturally interconnect in the retail environments. -

Microgeographies of Retailing and Gentrification
Australian Geographer, Vol. 32, No. 1, pp. 93–107, 2001 Microgeographies of Retailing and Gentri cation GARY BRIDGE & ROBYN DOWLING, University of Bristol, UK; Macquarie University, Australia ABSTRACT It has long been argued that gentri cation is a process of consumption as well as production but, in the main, analyses of consumption and gentri cation have only tangentially or anecdotally considered the retail spaces of gentri ed neighbourhoods. In this paper we investigate the nature of the retail landscapes of gentri cation, using empirical evidence from Sydney, Australia. We point to micro retailscapes that differ between gentri ed neighbourhoods that suggest a divergence of consumption practices between different groups of gentri ers. These consumption practices are considered both in terms of their relations to identity (through food and the conception of the body) and to the spaces of the city. The paper concludes by drawing out the implications for future research on the consumption practices of the new middle class and the working class in an international context. KEY WORDS Gentri cation; retailing; Sydney; new middle class; consumption. Introduction It has long been argued that gentri cation is a process of consumption as well as production (see Lees 1994a; Hamnett 1991). Living in inner-city neighbourhoods, in houses with a certain aesthetic sensibility is not only a strategy of capital, but also a lifestyle choice that expresses the identities of those who belong to a new middle class of professionals and service workers. Mills (1988), for example, has suggested that gentri ers seek to consume a particular home-based aesthetic. -

Integrated surface-subsurface water flow modelling of the Laxemar area Application of the hydrological model ECOFLOW Nikolay Sokrut, Kent Werner, Johan Holmén Golder Associates AB January 2007 This report concerns a study which was conducted for SKB. The conclusions and viewpoints presented in the report are those of the authors and do not necessarily coincide with those of the client. A pdf version of this document can be downloaded from www.skb.se Abstract Since 2002, the Swedish Nuclear Fuel and Waste Management Co (SKB) performs site investigations in the Simpevarp area, for the siting of a deep geological repository for spent nuclear fuel. The site descriptive modelling includes conceptual and quantitative modelling of surface-subsurface water interactions, which are key inputs to safety assessment and environmental impact assessment. Such modelling is important also for planning of continued site investigations. In this report, the distributed hydrological model ECOFLOW is applied to the Laxemar subarea to test the ability of the model to simulate surface water and near-surface groundwater flow, and to illustrate ECOFLOW’s advantages and drawbacks. -

Modelling Peatlands As Complex Adaptive Systems
MODELLING PEATLANDS AS COMPLEX ADAPTIVE SYSTEMS Paul John Morris Thesis submitted for the degree of PhD of the University of London, 22nd July 2009. Following examination, minor corrections submitted February 2010. Department of Geography, Queen Mary, University of London, 327 Mile End Road, London E1 4NS United Kingdom. 1 Abstract A new conceptual approach to modelling peatlands, DigiBog, involves a Complex Adaptive Systems consideration of raised bogs. A new computer hydrological model is presented, tested, and its capabilities in simulating hydrological behaviour in a real bog demonstrated. The hydrological model, while effective as a stand-alone modelling tool, provides a conceptual and algorithmic structure for ecohydrological models presented later. Using DigiBog architecture to build a cellular model of peatland patterning dynamics, various rulesets were experimented with to assess their effectiveness in predicting patterns. Contrary to findings by previous authors, the ponding model did not predict patterns under steady hydrological conditions. None of the rulesets presented offered an improvement over the existing nutrient-scarcity model. Sixteen shallow peat cores from a Swedish raised bog were analysed to investigate the relationship between cumulative peat decomposition and hydraulic conductivity, a relationship previously neglected in models of peatland patterning and peat accumulation. A multivariate analysis showed depth to be a stronger control on hydraulic conductivity than cumulative decomposition, reflecting the role of compression in closing pore spaces. The data proved to be largely unsuitable for parameterising models of peatland dynamics, due mainly to problems in core selection. However, the work showed that hydraulic conductivity could be expressed quantitatively as a function of other physical variables such as depth and cumulative decomposition. -
Groundwater Models: How the Science Can Empower the Management?
Groundwater Models: How the Science Can Empower the Management? N.C. Ghosh and Kapil D. Sharma National Institute of Hydrology, Roorkee, India Abstract Protection, restoration and development of groundwater supplies and remediation of contaminated aquifers are the driving issues in groundwater resource management. These issues are further triggered on and driven by the population expansion and increasing demands. To transform the ‘vicious circles’ of groundwater availabilities into ‘virtuous circles’ of demands, understanding of the aquifer behavior in response to imposed stresses and/or strains is essentially required. If groundwater management strategies are directed towards balancing the exploitations in demand side with the fortune of supply side, the goals of groundwater management can be achieved when the tools used for solution of the management problems are derived considering mechanisms of supply-distribution-availability of the resource in the system. Groundwater modeling is one of the management tools being used in the hydro-geological sciences for the assessment of the resource potential and prediction of future impact under different stresses/constraints. Construction of a groundwater model follows a set of assumptions describing the system’s composition, the transport processes that take place in it, the mechanisms that govern them, and the relevant medium properties. There are numerous computer codes of groundwater models available worldwide dealing variety of problems related to; flow and contaminants transport modeling, rates and location of pumping, artificial recharge, changes in water quality etc. Each model has its own merits and limitations and hence no model is unique to a given groundwater system. Management of a system means making decisions aiming at accomplishing the system’s goal without violating specified technical and non-technical constrains imposed on it. -

Modelling the Impacts of Climate Change on Shallow Groundwater Conditions in Hungary
water Article Modelling the Impacts of Climate Change on Shallow Groundwater Conditions in Hungary Attila Kovács 1,* and András Jakab 2 1 Department of Engineering Geology and Geotechnics, Budapest University of Technology and Economics, M˝uegyetemrkp. 1, 1111 Budapest, Hungary 2 Jakab és Társai Kft., 32 Jászóvár utca, 2100 Gödöll˝o,Hungary; [email protected] * Correspondence: [email protected] Abstract: The purpose of the present study was to develop a methodology for the evaluation of direct climate impacts on shallow groundwater resources and its country-scale application in Hungary. A modular methodology was applied. It comprised the definition of climate zones and recharge zones, recharge calculation by hydrological models, and the numerical modelling of the groundwater table. Projections of regional climate models for three different time intervals were applied for the simulation of predictive scenarios. The investigated regional climate model projections predict rising annual average temperature and generally dropping annual rainfall rates throughout the following decades. Based on predictive modelling, recharge rates and groundwater levels are expected to drop in elevated geographic areas such as the Alpokalja, the Eastern parts of the Transdanubian Mountains, the Mecsek, and Northern Mountain Ranges. Less significant groundwater level drops are predicted in foothill areas, and across the Western part of the Tiszántúl, the Duna-Tisza Interfluve, and the Szigetköz areas. Slightly increasing recharge and groundwater levels are predicted in the Transdanubian Hills and the Western part of the Transdanubian Mountains. Simulation results Citation: Kovács, A.; Jakab, A. represent groundwater conditions at the country scale. However, the applied methodology is suitable Modelling the Impacts of Climate for simulating climate change impacts at various scales.
