Coastal change and evolution are the product of physical drivers (e.g., waves) tightly coupled with human behavior. As climate change impacts intensify, demand is increasing for information on where, when, and how coastal areas may change in the future. Although considerable research investments have been made in understanding the physical drivers and processes that modify and shape coastal environments, many do not account for human behavior, compromising the accuracy of comprehensive future change predictions. We outline four social science approaches—historic case studies, simulations, longitudinal studies, and longitudinal studies supported by experimental data—that can be coupled with physical change information to support transdisciplinary understanding of future change. A fundamental need for each approach is more and better empirical data to better gauge human behavior. In addition, foundational investments in transdisciplinary collaboration help research teams support the integration of these approaches.

Sea Grant programs across the United States and its territories are working with coastal communities to enhance their resilience to hazards and weather extremes exacerbated by climate change. Drawing on the expertise of the authors, many of whom have multiple years or decades of experience in the Sea Grant network, the article identifies five key strategies that Sea Grant programs employ to support the process of coastal hazards and extreme weather adaptation and resilience-building. The application of these strategies, most of which have their roots in the historical legacy of extension, are then illustrated through summaries of current Sea Grant activities and projects, showcasing how they have been applied in real-world situations. These strategies allow Sea Grant programs to fill a unique and valuable niche in national efforts to enhance coastal resilience. The article concludes with a discussion of emerging challenges and recommendations for strengthening Sea Grant’s capacity to support adaptation in coastal communities into the future.

Many tools have been generated in recent decades to support decision-makers in understanding and acting on climate science, causing stakeholders in the Gulf of Mexico (Gulf) to repeatedly express the need for guidance when selecting climate resilience tools. The Climate and Resilience Community of Practice (CoP), Gulf of Mexico Alliance (GOMA), and the Northern Gulf of Mexico Sentinel Site Cooperative (Cooperative) developed and implemented an end-user driven process for tool creation. Research has suggested that integrating target end-users throughout tool development improves the probability a tool will be utilized, yet there is little practical guidance available on how to successfully design and implement an end-user driven tool development process. In this study, an end-user driven process and results from implementing the process during tool development are presented. Challenges, successful approaches, and lessons learned to support future tool development, especially for tools focused on sharing climate science are identified. Guidance is provided on needed expertise, timelines for engagement with target end-users, and methods on how to solicit, analyze, and assimilate end-user needs, perspectives, and priorities into a final product.

This paper reports on insights and lessons learned from stakeholder engagement, particularly focus groups, conducted during a multi-year, NOAA-sponsored transdisciplinary project. A major project goal was to demonstrate and communicate benefits of natural and nature-based features (NNBFs) (e.g., barrier islands, dunes, and marshes) in the northern Gulf of Mexico region through the lens of economic impacts and ecosystem services. Overall, the findings indicate economic impacts and ecosystem services can be challenging topics to communicate because of complexity in conceptualization and valuation. From our experiences, we recommend using “ecosystem services assessment” (ESA), a more encompassing, accurate, and understandable term to stakeholders. ESA recognizes the integrated human (or built) and natural ecosystem and holistic benefits provided by and to both. The paper concludes with a discussion of future research opportunities for improving ESA-oriented science and outreach.
