Communicating with Coastal Decision-Makers and Environmental Educators via Sea Level Rise Decision-Support Tools



Communicating about environmental risks requires understanding and
addressing stakeholder needs, perspectives, and anticipated uses for
communication products and decision-support tools. This paper
demonstrates how long-term dialogue between scientists and stakeholders
can be facilitated by repeated stakeholder focus groups. We describe a
dialogic process for developing science-based decision-support tools as
part of a larger sea level rise research project in the Gulf of Mexico. We
demonstrate how focus groups can be used effectively in tool development,
discuss how stakeholders plan to use tools for decision-making and
broader public outreach, and describe features that stakeholders perceive
would make products more usable.

1 Introduction

Communication about climate change and its effects often requires tailoring efforts toward specific audiences — in particular, toward audiences that may have decision-making power over policy and mitigation options [Moser and Dilling, 2011]. To prepare for sea level rise (SLR), coastal stakeholders — including resource managers, community planners, public officials, and environmental educators — need access to scientific information in readily-usable formats and channels [Tribbia and Moser, 2008]. While these stakeholder groups have diverse areas of expertise, they all have uses for information in specialized formats different from what many members of the lay public might require. For example, localized maps depicting various SLR scenarios may be used to support decision-making by resource managers or community planners, or serve as communication aids with which educators facilitate public discussions about risk.

The transition from useful to readily-usable information can be complex and requires careful communication efforts that are customized to specific audiences [Lemos, Kirchhoff and Ramprasad, 2012; Sheppard et al., 2011]. Such customized communication efforts occur within the broader context of a shift from a top-down, information-oriented “deficit” model of science communication towards dialogic and participatory communication models [National Academies of Sciences, Engineering, and Medicine, 2017]. In the latter approaches, the implications of scientific information (in the dialogic model) and the direction of scientific research (in the participatory model) are discussed and negotiated among scientists and audiences [Bucchi, 2008, pp. 75–76]. Dialogic and participatory models of science communication require both “strategic listening” to the information needs of audiences and “strategic organization” of communication teams comprised of subject-matter specialist scientists, social scientists, and science communication specialists [Pidgeon and Fischhoff, 2011]. Moreover, dialogic communication can facilitate interaction among members of the public as well as between laypeople and scientists [Frazier, Wood and Yarnal, 2010; Leon et al., 2015]. In the context of SLR, audience engagement often involves data selection and visualization as well as identifying key stakeholder groups for dialogue efforts [Akerlof, Covi and Rohring, 2017].

This paper reports on stakeholder focus groups conducted as part of a transdisciplinary research project, Ecological Effects of Sea Level Rise in the Northern Gulf of Mexico (EESLR-NGOM), to develop the project’s communication products (such as “fact sheet” handouts and an informational website), scientific SLR planning models, and other decision-support tools (henceforth referred to as “tools”) so they are relevant and readily usable for key regional stakeholders. EESLR-NGOM was a seven-year, United States National Oceanic and Atmospheric Administration (NOAA)-sponsored project [DeLorme et al., 2016; Kidwell et al., 2017] involving detailed assessments and process-based modeling to project the dynamic response of ecological habitats [Alizad et al., 2016], and future tide and hurricane storm surge and flooding potential under SLR scenarios along the northern U.S. Gulf [Bilskie et al., 2016; Passeri et al., 2016]. The focus groups were instrumental in fostering an atmosphere of dialogue that helped us understand the needs of stakeholders for information format, features, and functionality in order to better tailor communication towards these target audiences. Thus, this project serves as an example of how dialogue between scientists and stakeholders can be integrated into a long-term research project [Groffman et al., 2010].

Information about SLR and its projected effects on coastal communities is available on various subtopics, including physical science [Nicholls and Cazenave, 2010; Passeri et al., 2015; Bilskie et al., 2016], ecosystem response [Morris et al., 2002; Fagherazzi et al., 2012; Alizad et al., 2016], and economic impact and community resilience [e.g., Moser and Boykoff, 2013; Stephens, DeLorme and Hagen, 2016], and in various formats such as interactive map-based visualization tools [Stephens, DeLorme and Hagen, 2014]. Computer models in particular can aid decision-making by enabling audiences to explore “what if” scenarios based on available scientific knowledge [Addison et al., 2013]. For example, models can integrate SLR scenarios and potential restoration projects to assess feasibility and impacts at the regional and coastal-community scale. Nevertheless, challenges remain for making this information readily usable and relevant to stakeholders, including downscaling results of large-scale computer models to the community level [Dolan and Walker, 2006; Wang, Hagen and Alizad, 2013], incorporating local changes in coastline morphology [Plant, Thieler and Passeri, 2016], and understanding potential responses of coastal vegetation [Alizad et al., 2016]. Moreover, stakeholders require not just access to information, but support in incorporating it into their planning procedures and communication [Tribbia and Moser, 2008] as well as tools to help understand immediate risks and underlying physical, biological, and social processes [Stephens, DeLorme and Hagen, 2016].

Lemos, Kirchhoff and Ramprasad [2012] discuss the importance of transitioning useful to usable scientific information by recognizing the context wherein information will be used and recommending features, organization, and tools to support audiences’ decision-making. They propose a framework for facilitating this transition: perception of fit (of information to audience needs), interplay (of new knowledge with other information sources audiences use), and interaction (between information producers and audiences). Availability, usability, salience, and source credibility can all form barriers to information use in adaptation planning [Heiskanen et al., 2007; Moser and Ekstrom, 2010; Moser and Dilling, 2011]. During communication design, interaction among scientists, communicators, and audiences is crucial to help all parties understand content and format needs [Pidgeon and Fischhoff, 2011], as shown in previous examples of environmental risk communication projects that have incorporated user-centered design [e.g., Lathrop et al., 2012; Morrow et al., 2015; Roth et al., 2017].

Another aspect of information design that improves communication is consideration of different dimensions of usability. Communicators should consider physical (ability to find information), cognitive (assisting with decision making), and affective (aesthetic arguments for using the information) dimensions of usability when designing documents or information systems [Carliner, 2000]. These dimensions have been shown to affect interpretation of SLR information by coastal residents [Covi and Kain, 2015] and coastal resource managers [Stephens, DeLorme and Hagen, 2015].

The purpose of our paper is to address the research question: How do stakeholders perceive their informational needs and uses regarding SLR communication and decision-support tools? The stakeholders in the EESLR-NGOM focus groups (resource managers, community planners, public officials, and environmental educators) represented the primary audiences for the scientific information produced by the project. Therefore, we use the term “stakeholder” when discussing this primary audience and “audience” when referring to all potential audiences (including the general public).

2 Method

In this project, focus groups were integral to improve communication and build trust among scientists and stakeholders and foster engagement and participatory decision-making [Addison et al., 2013]. The objectives were to gain insight and better understand stakeholders’ SLR preparation experiences and operational and informational needs, solicit input on EESLR-NGOM’s scientific tool development, learn to translate the project’s research into readily-accessible and usable tools, generate outreach ideas, and collect feedback. We concentrate here on distilling stakeholders’ communication and decision-support tool-related perceptions, expectations, and recommendations to address our study’s research question.

Focus group interviewing can capture spontaneous comments, candid remarks, and diverse firsthand descriptions through group dynamics [Krueger and Casey, 2000; Stewart and Shamdasani, 2015] and is used to understand how various groups situate scientific issues within their own understandings [Hanson-Easey et al., 2015]. Key strengths of focus groups include potential to minimize researcher biases as participants respond in their own words [Eisenhauer and Nicholson, 2005], facilitating emergence of unplanned insights [Newig et al., 2008], and illuminating evolution of group understanding about a topic with repeated focus groups of returning participants [Morgan, Fellows and Guevara, 2008; Newig et al., 2008; Nind and Vinha, 2016]. Focus groups can foster high-level researcher-stakeholder interaction and enable participatory modeling to reduce the information usability gap [Lemos, Kirchhoff and Ramprasad, 2012], as well as help researchers understand stakeholder preferences for computer modeling assumptions [Jensen and Uddameri, 2009].

Six face-to-face focus groups of between eight and thirteen participants each and an overall total of 58 participants were conducted as part of EESLR-NGOM annual workshops (2011–2016) with the first being held in Year 1 of the project. The workshop agenda began with presentations on the current state of the scientific research and tool development. The project team of natural and social scientists and engineers provided overviews of the state-of-the-art in SLR impact assessments to a project advisory board of regional stakeholders (coastal resource managers and environmental education and communication specialists). The general content of the presentations, which varied year to year, always included communicating the project’s objectives, status, and improvements based on stakeholders’ feedback. Directly following the technical presentations, a purposive sample subset of workshop attendees (i.e., all regional stakeholders who were not scientists) convened privately to participate in the focus group. Group composition varied slightly each year, with fifteen participants contributing to two or more focus groups over the project duration.

An EESLR-NGOM social scientist, experienced in qualitative methods, moderated all groups except one in which she trained a science communicator to perform this role. Each group began with an introduction and explanation of objectives and procedures. The moderator then asked open-ended questions using a flexible interview guide [Berg and Lune, 2012]. Participant interaction was encouraged and the moderator listened actively, remained nonjudgmental, and asked occasional probing questions. Each group was audio-recorded with permission; had a research assistant taking notes, monitoring time, and managing logistics; and lasted about 90 minutes. All procedures were approved by the authors’ Institutional Review Board. The interview guide, developed from team consultation and literature review, consisted of open-ended questions about SLR preparation, operational and informational needs, input on EESLR-NGOM tool development, and outreach ideas. It was pretested and remained relatively consistent each year.

Audio-recordings were transcribed in entirety by the science communicator and social scientist and double-checked for accuracy. The complete data set consisted of 158 transcript pages containing 67,347 overall total words and 33 additional pages of notes. The data was analyzed systematically within and across the groups (i.e., annually and cumulatively). The approach was interpretive and involved first listening to the audio-recordings and reading all transcripts and notes carefully. Next, unrestricted “open coding” was performed by selecting and labeling distinct units of meaning (sentences, phrases, and words) based on the interpreted relevance of the data such that categories were developed inductively and not predetermined [Berg and Lune, 2012; Strauss and Corbin, 1998]. Then comparisons were made within and between the coded data to identify subcategories and relationships [Berg and Lune, 2012; Strauss and Corbin, 1998]. The social scientist shared preliminary results with the science communicator for possible further interpretation and refinement. This process produced some reordering of categories, introduced connections to frameworks in the literature that informed further analysis, and prompted improvements in wording used to label certain categories and themes. Agreement was readily reached that the presentation of findings was acceptable. The following section summarizes the findings.

3 Results and discussion

Overall, the study’s findings reveal that the participants were concerned about SLR, believed planning was imperative and offered important insights, were optimistic about EESLR-NGOM’s tools, and recommended a number of workable features. While various perspectives were represented, there was also much consensus. The results reflect three main themes, including: (1) how stakeholders plan to incorporate the tools into their work, (2) what features stakeholders perceive they need in order to make the tools usable, and (3) how the tools might be applied beyond the stakeholders’ immediate professional setting. Themes and subthemes are illustrated in Figure 1 and expanded below. Representative participant quotations are presented in Tables 13.


Figure 1: Three main themes derived from the study, with additional subthemes.

3.1 How stakeholders plan to incorporate the tools into their work

Participants had favorable reactions to the communication products and decision-support tools being developed and expected they would have high utility for their own professional responsibilities involving SLR risk assessment and resource management. Various anticipated uses for the tools were discussed, encompassing interrelated ecological and social dimensions of SLR. While most SLR studies provide guidance for the year 2100, in multiple instances stakeholders indicated desire for their planning efforts on 50 years or less. A primary reason for the short-term focus was to make decisions that would impact within the span of their own career and lifetime. Analysis identified four major ways stakeholders anticipated incorporating the tools into their own SLR planning, including using scenarios for guidance on: (1) designing restoration projects, (2) purchasing lands for habitat conservation, (3) prioritizing ecological projects, and (4) defending ecological projects. Representative quotations appear in Table 1.

Table 1: Representative quotations about how stakeholders plan to incorporate the tools into their work.

These results regarding stakeholders’ own anticipated uses indicate high salience in perception of information fit for application in decision making. Salience has been defined as “information being relevant to the specific context in which the decision is made” [Liu et al., 2008]. Perception of information fit is important as it bolsters climate information usability [Lemos, Kirchhoff and Ramprasad, 2012].

3.2 What features stakeholders perceive they need in order to make the tools usable

The focus groups discussed general and specific features they perceived would be useful, beneficial, or important for the tools. Preferred features like information format and characteristics can be considered factors that influence users’ perceptions of information fit, which influences usability [Lemos, Kirchhoff and Ramprasad, 2012]. Further, it has been acknowledged that usable information consists of three essential attributes: credibility (perception of information being dependable and high-quality), legitimacy (information being transparent and understandable), and salience [Liu et al., 2008]. Overall, participants desired accessible and accurate scientific evidence in a flexible format that would enable adjustments over time, across geographic domains, for multiple platforms, and for different levels of scientific knowledge and technical sophistication. Five preferred tool features were identified (appropriate simulation results, transparent assumptions, readily-understandable content and format, customization and interactive capabilities, and multi-platform availability), many of which align with essential attributes of usable information discussed in the literature. Each feature is described below, with representative quotations provided in Table 2.

  1. Appropriate Simulation Results. According to participants, an essential feature for the tools was simulation of appropriate data. Specifically, five types of simulated data were identified: SLR rates and impacts, salinity projections, large-scale SLR simulations, and local results. Regarding the latter, participants preferred tools that included details in predicting SLR impacts at the “parcel-level” (i.e., individual tract of land) to guide community planners in infrastructure-related decision making. These results also demonstrate desire for accurate data and indicate credibility is crucial in these stakeholders’ perceptions of information fit [Addison et al., 2013; Lindeman et al., 2015]. Further, the reported needs for local data suggest salience is also key in these stakeholders’ perceptions of information fit for decision-making.
  2. Transparent Assumptions. The focus groups also thought making the scientists’ assumptions about model limitations and uncertainty transparent to audiences was important. Explicit communication of assumptions was viewed as critical when downscaling model results for incorporation into local-scale tools. Two other features expected to help facilitate transparency included consistent scale bars and prominent source crediting. These preferences for displaying assumptions transparently are central to cognitive usability [Carliner, 2000] and support the idea that clearly communicating about complexity and uncertainty can improve model credibility [Addison et al., 2013].
  3. Readily-Understandable Content and Format. Additionally, participants thought tool content and formats should be readily understandable by audiences with different scientific expertise and technical knowledge levels. They advised information be presented straightforwardly. Five recommended features in this regard included: visualizations (especially maps), clear instructions, standardized explanations, context for usage, and case studies. Together, these results indicate translating and packaging the tools into readily-understandable content and formats would be effective in improving usability for heterogeneous audiences [Krantz, Monroe and Bartels, 2013].
  4. Customization and Interactive Capabilities. Customization has been defined as adjustments in design made at the end of the production process to meet an individual user’s needs [Lemos, Kirchhoff and Ramprasad, 2012]. The focus groups thought customization was imperative for the tools being developed. Interactive capabilities that allow flexibility in user control over multiple combinations of features aid in customization. Four preferred interactive capabilities were identified, including: zooming and searching at varying levels of scale and technical detail for both the natural and built environments, adjusting scenario inputs (e.g., sediment quantities, time increments) to assess different influential factors on SLR variations, and comparisons with and connections to other tools. These results suggest developing interactive capabilities of the tools would be an effective customization strategy to improve usability.
  5. Multi-Platform Availability. For accessibility by various stakeholders, participants believed the tools should be available in multiple platforms (including online) without requiring special software. A related aspect of flexible data format was tool mobility and accessibility on laptops or tablets, potentially for use in the field. These findings indicate offering multi-platform availability would be another effective customization strategy [Lemos, Kirchhoff and Ramprasad, 2012], as well as addressing affective usability by serving needs for portable information [Carliner, 2000].

3.3 How the tools might be applied beyond the stakeholders’ immediate professional setting

How the tools could be applied in broader contexts beyond EESLR-NGOM’s scope and participants’ own resource management responsibilities was a third theme in the focus group discussions. Participants were optimistic about tool adoption by other audiences (e.g., local officials, developers, community planners, general public) involved in social and ecological SLR planning. Several expected uses for the tools by others were identified. These include more precise and convincing SLR communication and decision support for: (1) ecologically-oriented SLR planning (such as that of EESLR-NGOM) including purchasing lands for habitat conservation, prioritizing projects, and justifying projects, (2) commercially-oriented SLR planning, especially for fishing-related industries, and (3) community-oriented SLR planning including critical infrastructure placement (e.g., emergency management, sewer treatment plants), development strategies, and related policy-making and actionable preparation. Representative quotations appear in Table 3. The finding that participants perceived much potential for tool application beyond EESLR-NGOM’s scope suggests the products are perceived as able to interplay with other existing tools. Whether and how well new information can interplay with existing information sources affects usability [Lemos, Kirchhoff and Ramprasad, 2012] and application to purposes beyond the immediate scope of a project.

3.4 Study implications

This study illustrates how scientist-stakeholder dialogue can be incorporated as part of communication efforts within a broader research project. The findings presented here contribute to an in-depth understanding of stakeholders’ perceptions of their anticipated uses of and desired features for the EESLR-NGOM communication products and tools. There was also an expressed desire to focus on the short-term (i.e., the next 50 years) as opposed to generations in the future (e.g., Year 2100). Participants expected these products would have high utility and serve a dual purpose: (1) provide accurate, scientific, place-based SLR ecological data in a flexible format to guide design and prioritization of SLR planning projects for the natural and built environments and (2) provide an accessible, credible, data-driven, multi-platform communications tool about SLR and EESLR-NGOM to convince and support diverse audiences to take actionable preparation. Both purposes were furthered by repeated focus groups, a social science method enabling meaningful stakeholder feedback.

Research on the usability of technical communication tools is audience- and context-dependent, and often requires long-term interaction with target audiences in order to understand their particular needs [Shneiderman and Plaisant, 2006]. While the specific results reported here may not, therefore, be generalizable to all other contexts, lessons learned may inform design of similar environmental communication products and decision-support tools. This paper demonstrates how a social science-based focus group approach can foster constructive communication of science within a broader research context, as recommended in the literature [Pidgeon and Fischhoff, 2011]. In particular, we demonstrate how a dialogic approach can help developers better understand stakeholders’ perceived needs and uses for SLR decision-support tools. Consequently, we believe our study’s findings transcend EESLR-NGOM and can well serve other related science communication efforts.

It was expected that the focus groups would yield insights about how stakeholders plan to incorporate the tools into their work and what features stakeholders perceive they need to make the tools usable. However, the third theme, how tools might be applied beyond the stakeholders’ immediate professional setting, was rather surprising. We had not anticipated the degree to which stakeholders envisioned using the tools for certain applications (e.g., public outreach to communities particularly vulnerable to SLR). Thus, the focus groups helped the team better understand how the stakeholders perceived the tools fitting into their broader contexts of understanding, communicating about, and responding to risks [Granderson, 2014].

Additionally, this paper demonstrates some benefits of qualitative social science methods for developing environmental and risk communication projects. Focus groups have strengths (e.g., flexibility, inclusivity) that fostered dialogue among participants and generated a variety of potential uses and recommended features for the SLR communication products and planning tools from participants’ viewpoints and experiences. Through this process, the team gained insights into context that are less likely to emerge through other approaches. Further, stakeholders were able to interact directly and repeatedly with information producers so the tools were developed in ways that were accessible and readily useable for them. This type of legitimate two-way interaction can build trust and enable co-production of usable information and tools [Heiskanen et al., 2007; Lemos, Kirchhoff and Ramprasad, 2012], build consensus among different interest groups on the need for action [Frazier, Wood and Yarnal, 2010], and contribute to project sustainability [Servaes, 2016]. It is particularly important in promoting technology acceptance by decision-makers [Addison et al., 2013] and other end-users [Trigg and Roy, 2007].

The focus group results assisted the EESLR-NGOM team in identifying key physical (navigability that assists in finding information), cognitive (assisting with decision-making), and affective (aesthetic) elements of usability [Carliner, 2000]. Each element influences audiences’ perception of fit of the information to their needs as well as the team’s understanding of how project results would interplay with other information sources that audiences already use [Lemos, Kirchhoff and Ramprasad, 2012]. For example, participants made comparisons between the EESLR-NGOM computer models and those underpinning other SLR visualization tools, and discussed how the new research results might be linked to information they use for management originating from other institutions in the region. Participants described the vast array of alternate models and tools they have at their disposal, which led to recognition that any new models, tools, and data produced must fit into that overall paradigm and add value to what already exists.

Participants also anticipated certain uses for the project products that the team had not considered primary (e.g., public outreach) and discussed ways the products could inform more effective locally-situated SLR messaging [Schweizer et al., 2009]. Through the project process, the EESLR-NGOM team came to a better understanding of the individual perspectives and contexts in which stakeholders would use scientific information. Therefore, what the team recognized as “usable” information and tools shifted in response to stakeholders’ perceived needs, and enabled better customization of communication products and strategies [Longnecker, 2016]. This illustrates a benefit of adopting a dialogic model of science communication, in which anticipated tool uses are not constrained by the preconceptions of the project scientists [Bucchi, 2008, pp. 75–76].

The results suggested another key consideration for stakeholder engagement in projects that involve computer modeling of geophysical and ecological dynamics and decision-support tools development. We found it was important to distinguish between the computer models and the associated visualization tools and other products that communicate the results of those models. While the risk communication literature argues for stakeholder participation in development of conceptual models about risk [e.g., Morgan et al., 2002], such participation is generally used to develop products that communicate the results of computer models rather than making changes to the models themselves [e.g., Lathrop et al., 2012; Roth et al., 2017; but see Jensen and Uddameri, 2009]. We found it necessary to clarify for stakeholders the distinction between the biogeophysics-based computer models that underlie the EESLR-NGOM project and the map-based visualization tool that enables users to explore results from the computer models. The focus groups, comprised of end-users, were intended to obtain feedback to make the decision-support tools and datasets usable for end-users rather than acquire feedback on the underlying computer models. It is noteworthy, however, that stakeholders provided valuable information that was also used to improve model inputs and validation by apprising the team of additional data sources [Stephens, DeLorme and Hagen, 2015]. Previous research has demonstrated that a dialogic communication can illuminate deficiencies in scientific models through practical experience, for example, in communication about radiation risks to English farmers [Wynne, 1989].

3.5 Future research recommendations

More research is needed to examine stakeholder perspectives in projects aimed to develop or improve localized environmental risk communication products and targeted decision-support tools [Moser and Dilling, 2011]. Future studies gathering participants’ input, especially via qualitative methods, would be beneficial for comparative and evaluative purposes. We recommend, in particular, that projects, including biogeophysical research projects (such as EESLR-NGOM), be open to feedback from non-specialist project participants, which can be fostered effectively with focus groups. As our experience confirms, the dialogue that ensues during these interactions is valuable to both researchers and participants for building trust and improving risk communication. However, we also note the importance of scientists recognizing the applied expertise of stakeholders [Suldovsky, McGreavy and Lindenfeld, 2017] and attention to the overall interaction dynamics [Phillips, 2011] for creating legitimate dialogue.

It is recognized that researchers must balance keeping complex tools simple enough for wide application and distribution for diverse audiences [van Aalst, Cannon and Burton, 2008]. This paper reports on efforts to engage with specific target audiences for the purpose of public communication of scientific results in formats that are useful and usable for these audiences. As such, we did not engage with the broader lay public in the project region about the risks associated with SLR. Further research on how the lay public may interpret and respond to communication tools, particularly web-based resources, would be valuable. Additionally, research on needs of the lay public, in addition to specialist stakeholder groups, for scientific information about SLR is recommended [Akerlof, Covi and Rohring, 2017; Lindenfeld et al., 2012]. Nonetheless, this project demonstrates that place-based, scientific, and non-specialized knowledge can be integrated to build trust, better understand the complex processes, and provide value to the appropriateness of potential tools to solve local problems.
