Across many social–ecological systems, policy makers and scholars increasingly call for science to inform policy. The science–policy interface becomes especially complex as collaborative approaches include multiple stakeholders working together across jurisdictions. Unfortunately little is known about how much and how science is used in collaborative governance for social–ecological systems. This exploratory study examines instrumental, conceptual, and symbolic use of science in a science‐rich collaborative planning case in the Puget Sound, USA. It also examines the influence of science, relative to other factors, in collaborative planning, and what factors affect it. Results from a survey and document analysis indicate the prevalence of conceptual use of science, with relatively little symbolic use. Some factors promoting conceptual and instrumental use discourage symbolic use. Overall, while science is seen as influential in this science‐rich context, its influence is balanced by local stakeholder preferences and contextual information. [ABSTRACT FROM AUTHOR]

In response to calls from previous scholarship for further bottom‐up examination of local government roles in environmental policy, the authors revisit local air agencies to examine two separate phenomena occurring in environmental federalism: one from the top down (second‐order devolution) and one from the bottom up (local activism). Using survey data from local air agencies on devolved authorities to set air quality standards and to enforce federal and/or state standards, the authors identify three different types of local agencies: state administrative subunits (only enforcement authority), fully devolved agencies (authority to both set and enforce standards), and activist agencies (neither authority). Further findings indicate that state administrative subunits and fully devolved agencies are likely functions of second‐order devolution, while activist agencies are likely functions of local activism. Conclusions suggest that both top‐down and bottom‐up approaches to environmental federalism are shaping local government roles in environmental management. [ABSTRACT FROM AUTHOR]

This article provides a historical background of the evolution of transboundary water governance and environmental diplomacy in the Great Lakes- St. Lawrence basin, with a focus on the International Joint Commission ( IJC), during the twentieth century. This study focuses on water quantity issues, such as diversions, canals, hydroelectric developments, control works, and water levels, revealing the range of artificial and natural impacts on water levels in the Great Lakes- St. Lawrence basin. Doing so provides for a revealing examination of the IJC, which has traditionally been the main forum in which Canada and the United States manage their environmental relations and border water issues, which allows for an engagement with a range of North American transboundary governance theories. While the IJC is often lauded as a model of transnational environmental cooperation, this paper demonstrates that the evolution of this bilateral institution up to the 1960s is more complicated.

Many governments have implemented environmental justice mandates requiring agencies to consider the implications of cleanup decisions for poor and/or minority populations. To the extent that this mandate alters decisions, it usually does so by considering the composition of a community in the present without adjusting for potential demographic changes that may occur over time. However, communities change and these changes are likely to affect how well an agency meets its environmental justice mandate over the long term. In this research, an agent-based model is introduced to simulate how alternative environmental remediation scenarios may affect environmental justice outcomes in a dynamic residential environment with two demographic classes with preferences for living in proximity to neighbors similar to themselves. Under these circumstances, there is unlikely to be one best strategy to achieve both environmental improvement and environmental equity, and a focus on valuable land is the least effective over the long run.

American environmental legislation cannot be fully explained under traditional interest-group theory, which emphasizes the success of well-financed, organized interests. One alternative explanation holds that the American public accepts a new environmental ethos that is protective of the natural world and human health. This study examines 100 years of state-level ballot questions on environmental policy and empirically establishes the emergence and persistence of this new environmental ethos as well as the changing nature of American support for environmental policy. This ethos emerges in 40 years, environmental policy making of this type has been increasingly citizen-led, inclusive of a wider variety of environmental problems, while embracing a greater range of policy solutions including those premised on more radical notions of humanity?s relationship with the natural world.
