Rising recreancy: flood control and community relocation in Houston,TX, from an environmental justice perspective

This article looks at issues of recreancy, environmental justice, and relocation as they relate to a flood control infrastructure project in inner city Houston. The main research questions were “What forms would recreancy take?” and “Can a project be environmentally just if recreancy is present?” Through the structural coding of 53 semi-structured interviews, recreancy was found even in a project where the sponsors used community cohesion as a guideline. This article illuminates the difficulties flood control project engineers face when working in local communities and argues that engineering issues are also social issues. Further, the relocatees within this flood control project voice some of the same concerns experienced by people relocated in other involuntary infrastructure development projects. The case outlined in this article could be used to better help those involuntarily relocated for flood control.     

Legal aspects of pesticides and toxic substances testing requirements

Abstract

The United States Environmental Protection Agency administers several laws and progrms through which it reviews the hazard potential of pesticides and other toxic substances which may present a risk to human health or the environment. The Agency's ability to assess hazard as required by law depends in part on test data developed through testing standards in Agency regulations. In reviewing the Agency's actions in this regard, the courts emphasize the importance of reasoned regulatory decisions. The legal requirements to assess risk and provide reasoned decisions in this regard establish the legal importance of testing guidelines and test data, and indicate that sound test methodology is as important legally as it is scientifically.

Assessing ecological risk on a regional scale

Society needs a quantitative and systematic way to estimate and compare the impacts of environmental problems that affect large geographic areas. This paper presents an approach for regional risk assessment that combines regional assessment methods and landscape ecology theory with an existing framework for ecological risk assessment. Risk assessment evaluates the effects of an environmental change on a valued natural resource and interprets the significance of those effects in light of the uncertainties identified in each component of the assessment process. Unique and important issues for regional risk assessment are emphasized; these include the definition of the disturbance scenario, the assessment boundary definition, and the spatial heterogeneity of the landscape. Although the research described in this article has been funded wholly or in part by the United States Environmental Protection Agency (EPA) through Interagency Agreement Number DW89932112-01-2 to the U.S. Department of Energy, it has not been subjected to EPA review and therefore does not necessarily reflect the views of EPA and no official endorsement should be inferred.
