Support for First Nations' Land Claims amongst Members of the Wilderness Preservation Movement: The Potential for an Environmental Justice Movement in British Columbia

In this paper we examine the relationship between identification with the environmental movement and support for First Nations' land claims in order to determine the potential for an environmental justice movement in British Columbia. The findings are based on survey data collected from members of a wilderness preservation movement organization based on Vancouver Island. The findings demonstrate that the stronger an individual identifies with the environmental movement, the more s/he supports linking First Nations' land claims to conservation campaigns. We conclude by proposing that the wilderness preservation movement could increase its mobilization potential and widen the scope of the movement by including First Nations' issues in their campaigns. It could do this by expanding its frame to include issues of environmental justice, thereby connecting environmental protection and fair access to resources.

A Framework for Incorporating the Impact of Water Quality on Water Supply Stress: An Example from Louisiana,USA

Water of poor quality can directly impact the budget of water available for key user groups. Despite this importance, methods for quantifying the impact of water quality on water availability remain elusive. Here, we develop a new framework for incorporating the impact of water quality on water supply by modifying the Water Supply Stress Index (WaSSI). We demonstrate the usefulness of the framework by investigating the impact of high salinity waters on the availability of irrigation water for agriculture in Louisiana. The WaSSI was deconstructed into sectoral components such that the total available water supply could be reduced for a particular demand sector (agricultural irrigation in this example) based on available water quality information. The results for Louisiana highlight substantial impacts on water supply stress for farmers attributable to the landward encroachment of saline surface water and groundwater near the coast. Areas of high salinity near the coast also increased the competition for freshwater resources among the industrial, municipal, and agricultural demand sectors in the vicinities of the municipal areas of Lake Charles, Lafayette, and Baton Rouge, Louisiana. The framework developed here is easily adaptable for other water quality concerns and for other demand sectors, and as such can serve as a useful tool for water managers.

Superfund,Hedonics, and the Scales of Environmental Justice

Environmental justice (EJ) is prominent in environmental policy, yet EJ research is plagued by debates over methodological procedures. A well-established economic approach, the hedonic price method, can offer guidance on one contentious aspect of EJ research: the choice of the spatial unit of analysis. Environmental managers charged with preventing or remedying inequities grapple with these framing problems. This article reviews the theoretical and empirical literature on unit choice in EJ, as well as research employing hedonic pricing to assess the spatial extent of hazardous waste site impacts. The insights from hedonics are demonstrated in a series of EJ analyses for a national inventory of Superfund sites. First, as evidence of injustice exhibits substantial sensitivity to the choice of spatial unit, hedonics suggests some units conform better to Superfund impacts than others. Second, hedonic estimates for a particular site can inform the design of appropriate tests of environmental inequity for that site. Implications for policymakers and practitioners of EJ analyses are discussed.     

Where the Waters Divide: First Nations,Tainted Water and Environmental Justice in Canada

Abstract

We have survived Canada's assault on our identity and our rights … Our survival is a testament to our determination and will to survive as a people. We are prepared to participate in Canada's future—but only on the terms that we believe to be our rightful heritage.

Wallace Labillois, Council of Elders, Kingsclear, New Brunswick

This paper argues for a strengthening of the theoretical relationship between neo-liberalism and environmental justice. Empirical research involving First Nations communities in southwestern Ontario suggests that neo-liberal reforms introduced in the mid-1990s were particularly discriminatory against Canada's indigenous peoples, serving to exacerbate historical disparities in health, environment pollution, and well-being. In particular, under neo-liberal reform in Ontario, recognition of environmental injustices has become much more difficult for First Nations communities. Furthermore, this ‘new’ form of environmental governance has broadly reduced legitimate opportunities for First Nations to participate in environmental governance that affects their health and welfare. In short, this research supports a widening of the definition of environmental justice advocated by David Schlosberg and others (Environmental Politics, 13(3) (2004), pp. 517–540; Agyeman, Bullard and Evans 2003 Agyeman, J., Bullard, R. D. and Evans, B. 2003a. “Joined-up thinking: bringing together sustainability, environmental justice and equity”.

Cambridge, MA: MIT Press.  [Google Scholar]; Akwesasne Task Force on the Environment, Research Advisory committee 1997; Di Chiro 1998 Di Chiro, Giovanna. 1998. “Environmental Justice from the Grassroots: Reflections on History, Gender and Expertise”. In The Struggle for Ecological Democracy: Environmental Justice Movements in the United States, Edited by: Faber, D. NY: Guilford.  [Google Scholar]) if we are to understand the subtle, complex and multiple ways that this new form of environmental governance is particularly harmful to marginalized groups, such as First Nations in Canada.

Suitability Analysis for Greenway Planning in China: An Example of Chongming Island

Suitability analysis for greenway planning was developed in the Western culture. When applying a suitability analysis to a very different sociocultural context such as China, it is necessary to identify what hinders or promotes it. Through an example of Chongming Island, this article demonstrates how to apply a suitability analysis for greenway planning in China. Furthermore, it argues that obstacles including a lack of data, peculiarity of capability scores within land use and a neglect of scientific group involvement are encountered in the process of applying suitability methods in Chongming or China. Early and sustained attention to such impediments could improve the success of suitability assessment in China. These research results are helpful for the planning and implementation of Chongming greenways.     

An inventory of wetland impoundments in the coastal zone of Louisiana,USA: Historical trends

We inventoried wetland impoundments in the Louisiana, USA, coastal zone from the late 1900s to 1985. Historically, impoundment of wetlands for reclamation resulted in direct wetland loss after levees (dikes) failed and the impounded area was permanently flooded, reverting not to wetland, but to open-water habitat. A current management approach is to surround wetlands by levees and water control structures, a practice termed semi-impoundment marsh management. The purpose of this semi-impoundment is to retard saltwater intrusion and reduce water level fluctuations in an attempt to reduce wetland loss, which is a serious problem in coastal Louisiana. In order to quantify the total impounded area, we used historic data and high-altitude infrared photography to map coastal impoundments. Our goal was to produce a documented inventory of wetlands intentionally impounded by levees in the coastal zone of Louisiana in order to provide a benchmark for further research. We inventoried 370,658 ha within the coastal zone that had been intentionally impounded before 1985. This area is equal to about 30% of the total wetland area in the coastal zone. Of that total area, approximately 12% (43,000 ha) is no longer impounded (i.e., failed impoundments; levees no longer exist or only remnants remain). Of the 328,000 ha still impounded, about 65% (214,000 ha) is developed (agriculture, aquaculture, urban and industrial development, and contained spoil). The remaining 35% (114,000 ha) of impoundments are in an undeveloped state (wetland or openwater habitat). In December 1985, approximately 50% (78,000 ha) of the undeveloped and failed impoundments were open-water habitat. This inventory will allow researchers to monitor future change in land-water ratios that occur within impounded wetlands and thus to assess the utility of coastal wetland management using impoundments.

Evaluating the Environmental Performance of Urban Parks in Mediterranean Cities: An Example from the Barcelona Metropolitan Region

In a context of increasing urban sprawl and water scarcity common to other Mediterranean cities, this article focuses on the urban parks in the Region of Barcelona (Catalonia, Spain) to examine how these parks are distributed in this region and to assess whether their design and management follow criteria adapted to Mediterranean environmental conditions, especially in what concerns water use. In order to evaluate the environmental performance of these parks, we selected four factors possibly influencing the adoption of park management practices at the local scale: urban density, population size of the municipality, municipal income per capita, and political orientation of the city council. After determining the location and area of urban parks in the region, we correlated these four explanatory factors with several management tasks extracted from two different samples of parks (one of 315 parks and another of 125 parks) and a survey of 86 city councils. Results show that, in general, urban parks were more frequent in large, dense, and left/green municipalities but that environmentally sound practices were more common in small and low-density municipalities. We conclude that changes in certain practices (especially the substitution of high water demanding species) could improve significantly the environmental performance of public spaces in large urban areas with Mediterranean climates. Our observations may be pertinent for other cities interested in the provision of environmental public goods such as parks that necessitate water for irrigation.     

Environmental Justice across the Rural Canadian Prairies: Agricultural Restructuring, Seed Production and the Farm Crisis

Much of the work completed thus far on environmental justice has focused on environmental issues that unfairly affect politically disenfranchised communities in the US. The farm crisis occurring across the Canadian Prairies is at a fundamental level, also a matter of social and environmental justice. Environmental justice, in an agricultural context, refers not only to the siting and operation of intensive livestock facilities but more broadly relates to the concerns of many about the contemporary reorganization of agriculture. Using a case study of recent developments in plant breeding and seed production, I will discuss some of the broad trends occurring across the Canadian prairies in agriculture and rural areas as issues of environmental justice.

'British Columbia Is Open for Business': Environmental Justice and Working Forest News in the Vancouver Sun

This paper analyses the Vancouver Sun's coverage of the Working Forest Initiative, which the provincial government of British Columbia (BC), Canada, introduced in 2002. The Working Forest originally defined forestry as the primary use of all forested Crown land in BC that was not within protected areas. By 2003, this policy initiative was transformed into a largely symbolic recognition of the importance of the forest industry. Through the Sun, the debate over the Working Forest is simplified into a conflict between a discourse of 'certainty and stability' for the forest industry and an oppositional discourse that challenges the conflation of the interests of forestry corporations with a reified 'general interest'. In the Sun, debate over the Working Forest is dominated by sources from government, environmental organizations and the forest industry. Other important news sources are rendered silent, including First Nations and forestry labour voices.

Environmental Justice,Local Knowledge,and Risk: The Discourse of a Community-Based Cumulative Exposure Assessment

While risk assessment continues to drive most environmental management decision-making, its methods and assumptions have been criticized for, among other things, perpetuating environmental injustice. The justice challenges to risk assessment claim that the process ignores the unique and multiple hazards facing low-income and people of color communities and simultaneously excludes the local, non-expert knowledge which could help capture these unique hazards from the assessment discourse. This paper highlights some of these challenges to conventional risk assessment and suggests that traditional models of risk characterization will continue to ignore the environmental justice challenges until cumulative hazards and local knowledge are meaningfully brought into the assessment process. We ask whether a shift from risk to exposure assessment might enable environmental managers to respond to the environmental justice critiques. We review the US EPA's first community-based Cumulative Exposure Project, piloted in Brooklyn, NY, and highlight to what extent this process addressed the risk assessment critiques raised by environmental justice advocates. We suggest that a shift from risk to exposure assessment can provide an opportunity for local knowledge to both improve the technical assessment and its democratic nature and may ultimately allow environmental managers to better address environmental justice concerns in decision-making.     

An Analysis of Spatial Clustering and Implications for Wildlife Management: A Burrowing Owl Example

Analysis tools that combine large spatial and temporal scales are necessary for efficient management of wildlife species, such as the burrowing owl (Athene cunicularia). We assessed the ability of Ripley’s K-function analysis integrated into a geographic information system (GIS) to determine changes in burrowing owl nest clustering over two years at NASA Ames Research Center. Specifically, we used these tools to detect changes in spatial and temporal nest clustering before, during, and after conducting management by mowing to maintain low vegetation height at nest burrows. We found that the scale and timing of owl nest clustering matched the scale and timing of our conservation management actions over a short time frame. While this study could not determine a causal link between mowing and nest clustering, we did find that Ripley’s K and GIS were effective in detecting owl nest clustering and show promise for future conservation uses.
