Coastal Ecosystem-Based Management with Nonlinear Ecological Functions and Values

A common assumption is that ecosystem services respond linearly to changes in habitat size. This assumption leads frequently to an “all or none” choice of either preserving coastal habitats or converting them to human use. However, our survey of wave attenuation data from field studies of mangroves, salt marshes, seagrass beds, nearshore coral reefs, and sand dunes reveals that these relationships are rarely linear. By incorporating nonlinear wave attenuation in estimating coastal protection values of mangroves in Thailand, we show that the optimal land use option may instead be the integration of development and conservation consistent with ecosystem-based management goals. This result suggests that reconciling competing demands on coastal habitats should not always result in stark preservation-versus-conversion choices.

Ecosystem Services as a Common Language for Coastal Ecosystem‐Based Management

Ecosystem-based management is logistically and politically challenging because ecosystems are inherently complex and management decisions affect a multitude of groups. Coastal ecosystems, which lie at the interface between marine and terrestrial ecosystems and provide an array of ecosystem services to different groups, aptly illustrate these challenges. Successful ecosystem-based management of coastal ecosystems requires incorporating scientific information and the knowledge and views of interested parties into the decision-making process. Estimating the provision of ecosystem services under alternative management schemes offers a systematic way to incorporate biogeophysical and socioeconomic information and the views of individuals and groups in the policy and management process. Employing ecosystem services as a common language to improve the process of ecosystem-based management presents both benefits and difficulties. Benefits include a transparent method for assessing trade-offs associated with management alternatives, a common set of facts and common currency on which to base negotiations, and improved communication among groups with competing interests or differing worldviews. Yet challenges to this approach remain, including predicting how human interventions will affect ecosystems, how such changes will affect the provision of ecosystem services, and how changes in service provision will affect the welfare of different groups in society. In a case study from Puget Sound, Washington, we illustrate the potential of applying ecosystem services as a common language for ecosystem-based management.

Ecology, Society, and the Quality of Social Life.

The twelve contributors to this volume, from ten different nations, are world-renowned sociologists who examine problems of ecology and world resources as they affect the quality of social life. Three different perspectives are employed: high technology, industrialization, and the problems of development; restructuring and alternatives of development; and social movements and social policies.

Coastal Resident Trust, Similarity, Attitudes, and Intentions Regarding New Marine Reserves in Oregon

ABSTRACT This article examined coastal resident attitudes and behavioral intentions associated with new marine reserves (MRs) in Oregon, as well as resident perceived similarity and trust in the lead managing agency (Oregon Department of Fish and Wildlife). Data were obtained from a survey of residents along the Oregon coast (n = 596). Most residents perceived moderate similarity and trust in the agency, had stronger attitudes toward potential advantages of MRs, and would vote in support for the establishment of these reserves. Those living nearest the reserves had the most positive attitudes and were most supportive. Residents who perceived themselves as similar to the agency were more likely to trust this agency, and those with higher trust had stronger attitudes toward advantages of MRs and less agreement with disadvantages of the reserves. Residents with stronger attitudes toward advantages were most likely to vote for MRs, whereas those who agreed with disadvantages were less supportive.

Agent-based tsunami evacuation modeling of unplanned network disruptions for evidence-driven resource allocation and retrofitting strategies

The M9 Cascadia subduction zone earthquake represents one of the most pressing natural hazard threats in the Pacific Northwest of the USA with an astonishing high 7–12% chance of occurrence by 2060, mirroring the 2011 devastating earthquake and tsunami in Japan. Yet this region, like many other coastal communities, is underprepared, lacking a comprehensive understanding of unplanned network disruptions as a key component to disaster management planning and infrastructure resilience. The goals of this paper are twofold: (1) to conduct a network vulnerability assessment to systematically characterize the importance of each link’s contribution to the overall network resilience, with specific emphasis on identifying the most critical set of links and (2) to create an evidence-driven retrofitting resource allocation framework by quantifying the impacts of unplanned network disruptions to the critical links on network resilience and retrofitting planning. This research used the city of Seaside on the Oregon coast as a study site to create the agent-based tsunami evacuation modeling and simulation platform with an explicit focus on the transportation network. The results indicated that (1) the network bridges are not equally important and some of the critical links are counterintuitive and (2) the diverse ways of spending the limited retrofitting resources can generate dramatically different life safety outcomes. These results strongly suggest that accurate characterization and measurement of infrastructure network failures will provide evidence-driven retrofitting planning strategies and inform resource allocations that enhance network resilience.

Community climate change beliefs, awareness, and actions in the wake of the September 2013 flooding in Boulder County, Colorado

Scholars and activists alike contend that extreme weather events may provide the best opportunity for raising public awareness and perhaps even instigating action related to climate change. We explore whether the September 2013 floods were associated with local climate change beliefs and actions after the event via an in-depth case study in Boulder County, CO. Based on analysis of local newspapers and policy documents, responses from an event-specific survey, and semi-structured interviews, we show that Boulder County residents readily connected the flooding event to climate change despite competing scientific claims about the link. Moreover, while the event did not necessarily alter existing climate change beliefs, it did create a greater sense of vulnerability to and increased awareness of the risks posed by climate change. In terms of climate change action after the event, residents and policymakers appeared to place a greater emphasis on adaptation to future extreme events, with a focus on building resilience through social capital. Yet, we also uncovered a complex relationship between social capital and resilience, particularly in terms of the impact of the event on already marginalized and vulnerable populations. This study adds to a growing body of research on climate change beliefs and actions in the wake of extreme weather events.
