Restructuring Beijing's Social Space: Observations on the Olympic Games in 2008

Two American geographers comment on the preceding analysis of restructuring of Beijing's social space (Feng et al., 2007) by presenting observations on the city's Olympic Games, forthcoming in the summer of 2008. The authors focus on some of the more salient geographical impacts stemming from construction, relocation, and related measures undertaken by the authorities to accommodate the event. Included in the paper are sections on environmental concerns (particularly air pollution), infrastructure (water supply, automobile traffic, and mass transit), and relocation and displacement of residents (particularly of migrants and other disadvantaged segments of the population).

In Situ Preservation of Wetland Heritage: Hydrological and Chemical Change in the Burial Environment of the Somerset Levels,UK

Abstract

In situ preservation is a core strategy for the conservation and management of waterlogged remains at wetland sites. Inorganic and organic remains can, however, quickly become degraded, or lost entirely, as a result of chemical or hydrological changes. Monitoring is therefore crucial in identifying baseline data for a site, the extent of spatial and or temporal variability, and in evaluating the potential impacts of these variables on current and future in situ preservation potential.

Since August 2009, monthly monitoring has taken place at the internationally important Iron Age site of Glastonbury Lake Village in the Somerset Levels, UK. A spatial, stratigraphic, and analytical approach to the analysis of sediment horizons and monitoring of groundwater chemistry, redox potential, water table depth and soil moisture (using TDR) was used to characterize the site.

Significant spatial and temporal variability has been identified, with results from water-table monitoring and some initial chemical analysis from Glastonbury presented here. It appears that during dry periods parts of this site are at risk from desiccation. Analysis of the chemical data, in addition to integrating the results from the other parameters, is ongoing, with the aim of clarifying the risk to the entire site.     

Introduction: global perspectives on gender–water geographies

This introduction summarizes the work featured in the themed section of Gender, Place and Culture titled ‘Global geographies of gender and water’. It brings into dialogue scholars investigating a variety of gender–water relationships at different scales, including: poisoned waterscapes; fishing practices; and the implications of neoliberal water policies. The authors featured purposefully engage with the multi-faceted ways in which experiences, discourses and policies of water are gendered, and how gender is created through processes of access, use and control of water resources. In bringing these articles together, we have consciously aimed to support inclusive, feminist collaborative work and to prioritize diversity.     

Fluid lives: subjectivities,gender and water in rural Bangladesh

This article seeks to contribute to the emerging debates in gender–water and gender–nature literatures by looking at the ways that gendered subjectivities are simultaneously (re)produced by societal, spatial and natural/ecological factors, as well as materialities of the body and of heterogeneous waterscapes. Drawing from fieldwork conducted in Bangladesh on arsenic contamination of drinking water, the article looks at the ways that gender relations are influenced by not just direct resource use/control/access and the implications of different types of waters, but also by the ideological constructs of masculinity/femininity, which can work in iterative ways to influence how people relate to different kinds of water. Conflicts and struggles over water inflect gendered identities and sense of self, where both men and women participate in reproducing and challenging prevailing norms and practices. As a result, multiple social and ecological factors interact in complex and interlinked ways to complicate gender–water relations, whereby socio-spatial subjectivities are re/produced in water management and end up reinforcing existing inequities. The article demonstrates that gender–water relations are not just intersected by social axes, as generally argued by feminist scholars, but also by ecological change and spatial relations vis-à-vis water, where simultaneously socialized, ecologized, spatialized and embodied subjectivities are produced and negotiated in everyday practices.     

Evaluation of soluble benzene migration in the Uinta Basin

Field sampling and mathematical modeling are used to study the long‐distance transport and attenuation of petroleum‐derived benzene in the Uinta Basin, Utah. Benzene concentration was measured from oil and oil field formation waters of the Altamont‐Bluebell and Pariette Bench oil fields in the basin. It was also measured from springs located in the regional groundwater discharge areas, hydraulically down‐gradient from the oil fields sampled. The average benzene concentration in oils and co‐produced waters is 1946 and 4.9 ppm at the Altamont‐Bluebell field and 1533 and 0.6 ppm at the Pariette Bench field, respectively. Benzene concentration is below the detection limit in all springs sampled. Mathematical models are constructed along a north–south trending transect across the basin through both fields. The models represent groundwater flow, heat transfer and advective/dispersive benzene transport in the basin, as well as benzene diffusion within the oil reservoirs. The coupled groundwater flow and heat transfer model is calibrated using available thermal and hydrologic data. We were able to reproduce the observed excess fluid pressure within the lower Green River Formation and the observed convective temperature anomalies across the northern basin. Using the computed best‐fit flow and temperature, the coupled transport model simulates water washing of benzene from the oil reservoirs. Without the effect of benzene attenuation, dissolved benzene reaches the regional groundwater discharge areas in measurable concentration (>0.01 ppm); with attenuation, benzene concentration diminishes to below the detection limit within 1–4 km from the reservoirs. Attenuation also controls the amount of water washing over time. In general, models that represent benzene attenuation in the basin produce results more consistent with field observations.     

Source water protection in a landscape of 'New Era' deregulation

The concept of source water protection (SWP) has gained prominence in the water resource literature. SWP consists of watershed and groundwater management for the protection of drinking water supplies. The logic behind SWP is that it is easier, cheaper and safer to protect a drinking water source from contamination than it is to remediate after contamination. SWP is largely a regulatory activity, requiring provincial government policy commitments. This research investigates the degree to which recent provincial deregulation plays a role in constraining SWP implementation at the local water utility level. The research was undertaken in British Columbia (BC) where, after 2001, the provincial government advanced widespread 'New Era' deregulation of social and environmental legislation. The apparent contradiction between government deregulation and government commitment to safe drinking water is interrogated. Data were collected using semi-structured interviews and document review in the Okanagan Basin. This article reveals that New Era deregulation initiatives have constrained local efforts to implement SWP on the ground. This article recommends that a single provincial agency should oversee drinking water in BC and that greater attention be given to regional governance for drinking water management in the Okanagan Basin.     

Wellsprings of Belonging: Water and Community Regeneration in Queensland

ABSTRACT This article considers how local communities in South Queensland make use of the cultural meanings encoded in water to articulate social connections and notions of belonging. Drawing on recent ethnographic research, it compares the activities of a community catchment group in Brisbane, and participants in a water festival in Maroochydore, exploring how each group engages creatively with local water sources to materialise particular beliefs and values about identity and belonging. Their creative efforts range from conventional attempts to strengthen local community ties through inclusion in catchment management, to more subversive visions, which resist inclusion in the mainstream and promulgate ‘alternative’ social and environmental values.

Resource and environmental management: connecting the academy with practice

The rewards and challenges related to a research program that involves interactions between basic and applied research are shared. Specific experience is examined regarding integrated water resource management, capacity enhancement in developing countries and writing textbooks. Key lessons include the manner in which applied research and practice inform and enhance basic research, the role of theoretical and conceptual frameworks in guiding applied research, the need to understand the distinction between multidisciplinary and interdisciplinary models and the importance of facilitating evolution from visions, strategies and plans to action.     

Screening Climatic and Non‐Climatic Risks to Australian Catchments

Emerging and future climatic change across the Australian continent has been identified as a significant threat to the successful sustainable management of the nation's water resources. However, the impacts of climate change must be viewed within the context of past, present and future climatic variability and human agency. A qualitative screening‐level risk assessment was undertaken for Australia's 325 surface water management areas by aggregating a suite of six relevant risk indicators. Four indicators addressed the antecedent conditions upon which future climate change will act. These included 50‐year trends in rainfall, the status of surface and groundwater development, and catchment condition. Two indicators addressed future drivers of supply and demand; specifically, projected changes in runoff and population. The results indicate that the management challenges currently experienced in Australia's population centres and key agricultural areas such as the Murray‐Darling Basin are likely to increase in future decades. Furthermore, the geographic distribution of net risk, inclusive of multiple biophysical and socioeconomic drivers, is more extensive than is suggested by consideration of surface water development and availability alone. Comparison of at‐risk catchments with the spatial distribution of various social and environmental assets identified a high degree of overlap among catchment risk and human populations, water storages, irrigated agricultural land, and wetlands of international significance. This suggests that the catchments of the greatest value are also those judged to be at greatest risk. Though considerable work remains in evaluating the security of Australia's water resources to climatic and other stressors, this study provides a first‐order scheme for prioritising the risks to which catchments are exposed and an assessment of how some key drivers are likely to interact to drive risk.
