Assessing Community Vulnerability to Ocean Acidification Across the California Current Ecosystem

Ana K. Spalding (Oregon State University), Arielle Levine (San Diego State University), Tessa Hill (University of California Davis), Lida Teneva (Ocean Science Trust)

West Coast stakeholders, including fishers and shellfish farmers reliant on key economically and culturally important species, have already experienced adverse consequences of ocean acidification (OA and other stressors. However, the human dimension of vulnerability and people’s capacity to adapt, particularly in highly resource-dependent economies, remains understudied. In times of changing ocean conditions, high levels of dependence on natural resources expose certain coastal communities to higher risks and vulnerability. Achieving healthy ocean ecosystems and coastal economies in state and federal waters requires cross-disciplinary work to understand what factors (environmental, economic, social, cultural) determine the vulnerability of coastal communities to environmental change, as well as the potential for developing strategies to adapt to these changes. People’s adaptive capacity in the face of environmental disturbance depends on community knowledge, networks, and practices, as well as institutional policies and strategies that support adaptation. This project will assess how 6 coastal communities in Oregon and California are experiencing environmental vulnerability to OA and what they are doing to adapt to OA and associated impacts; as well as evaluate barriers to and key factors for coping in different contexts that can help inform policies to foster and support more resilient communities.The overarching goals of this project are to fill knowledge gaps about the vulnerability and adaptive capacity of coastal communities to OA and other environmental stressors in order to a)support thriving and resilient coastal communities along the U.S. West Coast and b) to support OA policy and decision-making at the state level of governance.

Vulnerability and Adaptation to Ocean Acidification Among Pacific Northwest Mussel and Oyster Stakeholders

David J. Wrathall, George Waldbusser, and David Kling, Oregon State University

Ocean acidification (OA) is already harming shellfish species in the Pacific Northwest, a global hotspot of OA. While OA poses a threat to regional communities, economies, and cultures that rely on shellfish, identified gaps remain in adaptive capacity and vulnerability of several stakeholders. This project will address these gaps by extending long-standing collaborative OA vulnerability research with shellfish growers to include other shellfish users (e.g. port towns, Native American tribes and shellfish sector employees). The project includes five objectives: 1) Map variations in shellfisheries’ exposure to OA and identify those that are most sensitive, 2) quantify production losses from OA and costs of investment in adaptation 3) Identify potential pathways for adaptation, 4) identify key technological, institutional, legislative, financial and cultural barriers to OA adaptation, 5) evaluate the cost of potential adaptation strategies, and develop behavioral models to predict the likelihood of users adopting specific adaptation strategies. The research is designed to identify key vulnerabilities, determine the cost of OA to Pacific Northwest shellfish stakeholders, and to model adaptation pathways for maximizing resilience to OA. The adaptation framework developed here will be replicable in other shellfisheries yet to experience OA impacts.

The Olympic Coast as a Sentinel: An Integrated Social-Ecological Regional Vulnerability Assessment to Ocean Acidification

Jan Newton, University of Washington

The Olympic Coast, located in the Pacific Northwest U.S., stands as a region already experiencing effects of ocean acidification (OA). This poses risks to marine resources important to the public, especially local Native American tribes who are rooted in this place and depend on marine treaty-protected resources. This project brings together original social science research, synthesis of existing chemical and biological data from open ocean to intertidal areas, and model projections, to assess current and projected Olympic Coast vulnerabilities associated with OA. This critical research aims to increase the tribes’ ability to prepare for and respond to OA through respective community-driven strategies. By constructing a comprehensive, place-based approach to assess OA vulnerability, decision-makers in the Pacific Northwest will be better able to anticipate, evaluate and manage societal risks and impacts of OA. This collaborative project is developed in partnership with tribal co-investigators and regional resource managers from start to finish and is rooted in a focus on local priorities for social, cultural, and ecological health and adaptive capacity.
