Marginalization by collaboration: Environmental justice as a third party in and beyond CALFED

Governance and planning of ecosystem and water management within the California Bay-Delta, a critical component of California's water economy, have been characterized by a range of innovations in collaboration and conflict resolution. Despite legal mandates to incorporate environmental justice, the California Bay-Delta Authority's (CBDA) policy-development process and the subsequent Delta Vision process have systematically marginalized the role of environmental justice in California's water policy. We suggest that environmental justice in Bay-Delta planning can be understood as a “third party” with a tenuous seat at the CALFED water management table. As such environmental justice is a useful lens through which to assess the state's broader commitments and capacities relative to equity as a planning principal and outcome. We interpret the fate of environmental justice within Bay-Delta planning as indicative of the inherent tensions between systems based on increasing market dominance and state legitimation and the values of environmental justice based on distributive, procedural, and cognitive justice. We construct a model of marginalization and environmental injustice in collaborative planning to illustrate these tensions. We draw upon experiences of members of the Environmental Justice Sub-Committee of CBDA's Bay Delta Public Advisory Committee, as well as interviews with other key environmental justice interests, and a comprehensive review of internal and public CBDA documents relating to the environmental justice program including budgets and program plans, and ethnographic field work. We conclude that by learning from the mistakes of Bay-Delta planning, a positive model of collaborative, environmental justice-based planning for water and ecosystem management is possible.     

Repetitive flood victims and acceptance of FEMA mitigation offers: an analysis with community-system policy implications

Of all natural disasters, flooding causes the greatest amount of economic and social damage. The United States' Federal Emergency Management Agency (FEMA) uses a number of hazard mitigation grant programmes for flood victims, including mitigation offers to relocate permanently repetitive flood loss victims. This study examines factors that help to explain the degree of difficulty repetitive flood loss victims experience when they make decisions about relocating permanently after multiple flood losses. Data are drawn from interviews with FEMA officials and a survey of flood victims from eight repetitive flooding sites. The qualitative and quantitative results show the importance of rational choices by flood victims in their mitigation decisions, as they relate to financial variables, perceptions of future risk, attachments to home and community, and the relationships between repetitive flood loss victims and the local flood management officials who help them. The results offer evidence to suggest the value of a more community-system approach to FEMA relocation practices.     

宝钢林地土壤有机碳含量的研究

通过对宝钢厂区4种不同污染程度区内,不同林分和不同树种下土壤0～20cm、20～40cm基本理化性质和有机碳含量的测定,分析城市工业环境下林地土壤有机碳含量的特征,以实现合理的绿化布局,提高绿地减碳效益。结果表明:工业区林地土壤有机碳具有"表聚作用";清洁区内落叶阔叶林土壤有机碳含量高,建议多种柳树;轻度污染区内针阔混交林含量高,针阔混交后土壤有机碳含量明显高于针叶林和常绿阔叶林,建议多种雪松+广玉兰和雪松+香樟;中度污染区和严重污染区内常绿阔叶林有机碳含量高,建议分别多种蚊母和女贞,同时严重污染区应丰富植被类型。     

Attitudes of Canadian Pig Producers Toward Animal Welfare

As part of a larger study eliciting Canadian producer and non-producer views about animal welfare, open-ended, semi-structured interviews were used to explore opinions about animal welfare of 20 Canadian pig producers, most of whom were involved in confinement-based systems. With the exception of the one organic producer, who emphasized the importance of a “natural” life, participants attached overriding importance to biological health and functioning. They saw their efforts as providing pigs with dry, thermally regulated, indoor environments where animals received abundant feed, careful monitoring and where prospective disease outbreaks could be minimized and controlled. Emphasis was also placed on low-stress handling and agreeable working conditions which were believed to promote good animal care. The fact that pigs tend to respond to such conditions with steady growth reinforced the belief that good welfare was provided. Participants supported the use of sow gestation stalls, but with some reservations, and expressed concern about welfare problems that could occur if sows were grouped. Invasive procedures (castration, tail-docking, teeth clipping) were recognized as painful but were accepted because they were seen as: (1) necessary for sales or management; (2) satisfactory trade-offs to prevent worse welfare problems such as injury or infection; or (3) sufficiently short-term to be relatively unimportant. Participants were adamantly opposed to animal neglect and some welcomed actions of animal protectionists that expose poor care. Producers also welcomed natural-science-based approaches to improving animal welfare. The findings contribute to a broader effort to identify overlapping values among different stakeholder groups as a basis for formulating mutually agreeable, farm animal care and handling polices.     

An overview of the gulf coast aerosol research and characterization study: the Houston fine particulate matter supersite

The Gulf Coast Aerosol Research and Characterization Study ([GC-ARCH], also known as the Houston Fine Particulate Matter [PM] Supersite) examined the spatial and temporal variability in fine PM source contributions and composition and the physical and chemical processes that govern PM formation and transformation in southeastern Texas. This was accomplished through the analysis of data collected in a 16-month field sampling program (August 2000 through November 2001). Three core sites and approximately 15 peripheral sites, jointly operated by the study team and the Texas Commission on Environmental Quality (TCEQ), were used. Key scientific findings related to spatial and temporal variability in fine PM concentrations, sizes and composition of the fine PM, the strength of primary emission sources and causes of secondary fine PM formation are reported.
