Community engagement as a component of revitalization: Lessons learned from the Technical Outreach Services to Communities programme

Community involvement has been identified as an important factor in the successful redevelopment of contaminated land, and access to technical resources has been a barrier for some communities. This paper describes how the US Environmental Protection Agency funded Technical Outreach Services to Communities programme was used to support four communities involved in land revitalization. The four New England case studies were used to retrospectively draw lessons learned that could be useful to others interested in similar community work. We suggest that the broad lessons point to four factors for success, namely, where there is: (1) a common vision in the community; (2) a cohesive community; (3) an opportunity for co-learning; and (4) a commitment among the parties for long-term engagement. We conclude that technical support can serve as a useful framework for developing trustful and long-term relationships with communities.     

Revitalizing neighbourhoods through sustainable brownfields redevelopment: Principles put into practice in Bridgeport, CT

This article chronicles activities and approaches carried out in working with community partners and public and private stakeholders in advancing revitalization within Bridgeport, CT. The approach described utilizes brownfields redevelopment as a focal point for a stakeholder process whose goal is neighbourhood revitalization. Two neighbourhoods—the Went End and East End—are the focus for major stakeholder-driven brownfields redevelopment processes. The article defines key elements of the stakeholder process including: involvement at several levels from neighbours to the site to the Mayor's office and beyond, a risk communication process that incorporates the broad concerns of the stakeholders including crime and violence, and the need for ongoing oversight and management throughout the redevelopment process.

False-negative prenatal exclusion of Wiskott-Aldrich syndrome by measurement of fetal platelet count and size

The study of the fetal platelet count and size can, according to the literature, be used for the prenatal diagnosis of the Wiskott-Aldrich syndrome (WAS). So far, no affected fetuses have been identified by this method. All pregnancies in which this method had been applied to resulted, as correctly predicted, in the birth of normal children. Here we report on a familial case of WAS where the haematological parameters failed to reveal the affected second child. Hence we assume that the platelet count and size of platelets remain normal in fetuses with WAS to the gestational age of 22 weeks and cannot be used for prenatal diagnosis.     

Traffic exposure in a population with high prevalence type 2 diabetes – Do medications influence concentrations of C-reactive protein?

Type 2 Diabetes (T2D) and particulate air pollution are associated with inflammatory dysregulation. We assessed the modifying effects of diabetes medications on the association of C-reactive protein (CRP), a marker of inflammation, and traffic exposure in adults with T2D (n = 379). CRP concentrations were significantly positively associated with residence ≤100 m of a roadway, >100 m and ≤200 m of a roadway and increased traffic density for individuals using insulin. For individuals using oral hypoglycemic medications (OHAs), CRP was significantly negatively associated with residence >100 m - ≤200 m of a roadway and multiple roadway exposure in an interaction model. Among people with diabetes, individuals on insulin appear to be most vulnerable to the effects of traffic exposure. Disease severity among insulin users may promote the pro-inflammatory response to traffic exposure, though diabetes medications may also modify the response. Possible anti-inflammatory effects of OHAs with traffic exposure merit further evaluation.     

Sustainable brownfields redevelopment and empowering communities to participate more effectively in environmental decision-making

The mitigation and reuse of contaminated land is a central element of environmental risk management practice in high-income nations. In the United States, with approximately 1500 Superfund sites (National Research Council, 1991), over 400,000 hazardous waste sites (Environmental Research Foundation, 1993) and an indeterminate number of sites that are qualitatively less contaminated, generally known as 'brownfields', there is ample opportunity for environmental professionals interested in becoming actively involved in such work. The reuse of previously developed plots of land is an important environmental risk management strategy as well as a primary trajectory for advancing communities through local decision-making that seeks economic, aesthetic or recreational advantages. This edition of Local Environment will explore this topic from a variety of perspectives.
