Research Priorities for Achieving Healthy Marine Ecosystems and Human Communities in a Changing Climate

Introduction

Human health and well-being are intricately linked to natural environments, including marine ecosystems (Whitmee et al., 2015). Around the world, seafood provides critical nutrition to more than 3 billion people (Béné et al., 2016; Golden et al., 2016; FAO, 2018). Fisheries and aquaculture directly employ more than 59.6 million people (FAO, 2018) and provide livelihoods for three to four times as many people through ancillary professions (e.g., processing, marketing, equipment production) (FAO, 2012; Teh and Sumaila, 2013). Marine ecosystems play a major role in global carbon sequestration and oxygen production (Duarte and Agustí, 1998; Sabine et al., 2004; McLeod et al., 2011; Pendleton et al., 2012). Healthy coral reefs, mangrove forests, and seagrass meadows are increasingly recognized as cost-effective natural buffers protecting coastal communities against flooding and coastal erosion (Spalding et al., 2014; Guannel et al., 2016; Narayan et al., 2017; Beck et al., 2018; Reguero et al., 2018), in addition to their role in carbon cycling and supporting fisheries (Duarte et al., 2013). Additionally, marine organisms are harvested for use as fertilizer, animal feed, and medical compounds (Froehlich et al., 2018b). Healthy marine ecosystems support a wide variety of industries and livelihoods, as well as the supply chains that support these sectors (World Bank, 2012; National Oceanic and Atmospheric Administration and National Marine Fisheries Service [NOAA-NMFS], 2017; Spalding et al., 2017). Importantly, ocean systems and species are valued for intrinsic, sociocultural, aesthetic, spiritual, recreational, and other reasons (Chan et al., 2012a).

Currently, a number of anthropogenic stressors threaten the relationships described above (reviewed in Jackson, 2010; Boyd, 2011; Halpern et al., 2012; Pendleton et al., 2016), and localized activities (e.g., pollution, sedimentation, overfishing, blast fishing) represent immediate and direct threats to marine ecosystems (Jackson et al., 2001; Thrush et al., 2004; Diaz and Rosenberg, 2008; Burke et al., 2011). Globally, climate change is emerging as the primary threat to marine social–ecological systems, with increases in ocean temperature, acidification, and sea-level rise increasingly affecting ocean ecosystems and vulnerable coastal communities (IPCC, 2019). As we confront a future of increasing global mean surface temperatures (Allen et al., 2018), increasing environmental variability (Sydeman et al., 2013), and increasing human populations (United Nations Department of Economic and Social Affairs Population Division, 2017), we anticipate amplification of these stressors and changes to relationships between human communities and marine ecosystems (Hoegh-Guldberg et al., 2018; IPCC, 2019).

A number of global initiatives converge in the importance of addressing these issues. The United Nations Sustainable Development Goals (SDGs) established 17 interlinked targets (United Nations, 2015; International Council for Science [ICSU], 2017) for achieving social and environmental well-being, including to “conserve and sustainably use the oceans, seas and marine resources for sustainable development” (SDG 14, “Life Below Water”). The Paris Agreement (United Nations Framework Convention on Climate Change [UNFCCC], 2015) includes goals related to the health of oceans and coastal communities such as enhancing adaptive capacity and resilience, and reducing damages to communities, in addition to focusing on climate change mitigation. The Convention on Biological Diversity (CBD) Aichi Biodiversity Targets (CBD, 2010) established 20 targets to improve the status of biodiversity, including increasing protected areas and sustainable fisheries, and enhancing climate resilience and sustainable ecosystem services. Several upcoming initiatives will include articles pursuant to healthy marine social–ecological systems, including the CBD post-2020 global biodiversity framework, and the United Nations Decade of Ocean Science for Sustainable Development (2021–2030). To achieve these initiatives in the context of projected climate and population trajectories, it is necessary to proactively identify research gaps and questions that, if addressed, would promote the greatest strides toward achieving a globally sustainable, just, and healthy future for marine social–ecological systems.

Ensuring healthy marine social–ecological systems in the future depends on how societies adapt and develop in the face of climate change. This will require broad, coordinated actions to reduce global emissions, protect existing natural carbon sinks (e.g., blue carbon), and increase the adaptive capacity of human communities and marine organisms to better cope with and recover from climate impacts. To accomplish these objectives, we need recommendations that consider ecological actions together with actions that affect policy, governance, and human behavior, as well as well-being, cultural diversity, and justice (Christie et al., 2003; Hallegatte and Mach, 2016; Wyborn et al., 2016; Claudet et al., 2020). In order for management to be proactive, rather than reactive, we need to understand what we need to know well in advance of the time it is needed.

To develop more integrative and proactive solutions, we engaged a diverse international and cross-sector team in a series of exercises to identify research questions and collaborations needed to rapidly promote sustainable and just marine social–ecological relationships, given current projections on climate change and human demographics. Our team sought to provide diverse perspectives on what kinds of knowledge could lead to feasible actions, and to better choices among possible solutions. This process included a retrospective analysis of the major events over the last 60 years that have shaped today’s marine social–ecological systems, as well as identification of unanticipated events or synergisms that lead to substantial change in marine ecosystems directly, or indirectly, by driving change in human behavior (Duarte, 2014). We present results from these efforts first as they help frame the questions. We then present 9 priority research areas and 46 research questions that, if answered now, could transform current approaches to marine sustainability. We then provide further detail on eight questions consistently identified as critically important and currently unaddressed.

Materials and Methods

The methods we used in this study are drawn from transdisciplinary research, which aims to “produce new knowledge by integrating different scientific and extra-scientific insights [with the goal of contributing] to both societal and scientific progress” (Jahn and Keil, 2015). This approach is well suited for complex problems with high uncertainty, multiple stakeholders, and diverse decision-making contexts. Transdisciplinary research groups typically benefit from a broad inclusion of worldviews, skills, and experience (Lynch et al., 2015). To this end, we assembled an international team with experience in investigative journalism, faith and secular community engagement, big data, art, indigenous knowledge, law and policy, climate change, marine ecology, fluid and geochemical modeling, political economy, public communication, conservation planning, and conservation psychology. The team (including coauthors) included representatives from academia, different levels of government, and the non-profit and private sectors.

Participants were presented with the orienting question, “If we were managing oceans in 2050 and looking back, what science, primary, or synthetic, would wish we had invested in today?” We assumed an increase of 1.5°C in global mean surface temperature by 2050 (Allen et al., 2018), and population of 9.8 billion by 2050 (United Nations Department of Economic and Social Affairs Population Division, 2017). Several activities were undertaken to create joint understanding of the sustainability problem to be addressed, and to collaboratively define specific research questions (Lang et al., 2012; Bengston, 2018).

First, we engaged in a retrospective analysis of major events over the last 60 years that have shaped today’s marine social–ecological systems. This technique (i.e., looking back twice as far as you look forward) is used to identify past trends and disruptions that could help illuminate the influences that current actions may have on the future (Saffo, 2007) and can provide guidance for future scenario planning by increasing idea generation (Rollier and Turner, 1994). We engaged in structured brainstorming of events, developments, and trends across the areas of society, technology, environment, economy, and politics that have affected oceans, and society’s relationship to coasts and oceans. Although not exhaustive, this reflective process highlighted the role of technological advances, politics, and disaster as key drivers of major changes in ocean condition and health in the past 60 years. Results of this exercise are presented.

Next, small group and plenary exercises were designed to promote new opportunities for engagement and discourse and draw out diverse perspectives, to maximize the potential of group wisdom while reducing common pitfalls (Gregory et al., 2012). Kantor’s Four-Player Model (2012) from family psychology was used to purposefully move individuals through different modes of communication to increase self-awareness of biases and default roles in group conversation. We then used scenario planning and a modified form of causal layered analysis (CLA; Inayatullah, 2003) to explore four alternative futures (Bengston, 2018), delineated by two axes: social connection (from fragmented to connected) and environmental health (from collapsed to sustained) (Merrie et al., 2018; Supplementary Figure S1). Participants discussed four future scenarios which were based in part on the shared socio-economic pathways (SSPs) developed for climate change research (O’Neill et al., 2017). We used CLA to explore underlying patterns and root causes that could lead to each alternative future. The scenarios were then used as a basis for discussion of research needs and opportunities.

Finally, we used a modified Delphi technique (Boulkedid et al., 2011; Mukherjee et al., 2015) to derive a list of priority research questions. We conducted three rounds of question generation and refinement consisting of a physical meeting and two iterative remote evaluations. The first round consisted of a 2-day physical meeting in which participants were engaged in question generation and refinement. We asked participants to focus on novel questions that were not already part of an active research agenda they were aware of, and which, if answered, could transform ocean management for the new realities of climate change. A total of 111 questions were recorded anonymously. Prior to the conclusion of the physical meeting, participants worked in teams to rank questions in terms of feasibility and impact. The second round of engagement was conducted after the physical meeting. Participants were given additional time to reflect on the full list of questions and were asked to independently identify 10 research questions from the original list they considered most important and currently unaddressed. These exercises were combined to produce a semifinal list of questions. In the third round of review, we refined the list of questions to eliminate redundancies and improve clarity, resulting finally in the 46 questions presented here. We invited all participants to review and provide feedback on the final list of questions. We provide further detail for eight research questions consistently identified during the three rounds as having both high feasibility and impact toward achieving more sustainable and just marine social–ecological systems.

Results and Discussion

Retrospective Analysis: Recent Events Shaping Marine Social–Ecological Systems

Our reflective process on the historical trends, events, and developments that have led to the present state of marine social–ecological systems highlighted the role of technology (e.g., the invention of plastics), politics (e.g., United Nations Convention on the Law of the Sea), and disaster (e.g., collapse of the Peruvian anchoveta fishery) as key drivers of major changes in ocean condition and health over the past 60 years (Figure 1 and Supplementary Table S1). While not exhaustive, the resulting perspective contributes toward a broader understanding of the processes that have shaped our current reality.

FIGURE 1

Figure 1. Retrospective timeline of the major events over the last 60 years that have shaped today’s marine social–ecological systems, as well as those identified as both unanticipated and transformative (marked by ‡). Further details including descriptions of each event can be found in Supplementary Table S1.

In addition to identifying steady pressures that drove change, we also identified a number of transformational events that were not widely anticipated but radically shifted behavior, politics, and perception around use and management of the marine environment (Figure 1 and Supplementary Table S1). Some of these events were the effect of sustained global processes (e.g., pollution, oil mining) or purposeful engagement (e.g., the movie Jaws). Others were sudden and relatively local, yet had far-reaching effects.

For example, the BP Deepwater Horizon oil spill in the Gulf of Mexico in April 2010 affected over 650 miles of Gulf coast habitats in a highly productive ecosystem, and resulted in major environmental, economic, and health damages (Graham et al., 2011). Among the unintended consequences associated with this event, Gulf oyster populations, which once were some of the best remaining in the world (Beck et al., 2011), were reduced 90% following the spill, but not by oil. Rather, they were decimated by major freshwater releases in southeastern Louisiana motivated by the mistaken assumption that releases from the Mississippi basin would “push” and keep oil offshore. Further, demand for unaffected oysters and overfishing has contributed to the collapse or near-collapse of oyster fisheries and has led to major social change in places such as Apalachicola and Cedar Key, FL.

Another example is the 1956 outbreak of disease in Minamata, Japan, which eventually led to the diagnosis of over 2200 individuals with Minamata disease (methylmercury poisoning), shaped national and international policy on mercury pollution in marine systems, and led to widespread research and public health messaging on the consumption of affected marine organisms in which mercury bioaccumulates (e.g., shellfish, tuna). This event was preceded by more than 30 years of wastewater discharge containing methylmercury into Minamata Bay. However, despite conclusive findings by 1959, wastewater discharge was not limited until a second outbreak of Minamata disease in 1965. Due to the study of affected individuals it is now well-understood that the bioaccumulation of high levels of mercury due to consumption of affected seafood led to neurological damage in patients, as well as health disorders in unborn children (Harada, 1995). The Minamata disaster had broad and long-lasting consequences. The public campaigns in response to the Minamata disaster are argued to have contributed to the post-WWII democratization of Japan (George, 2002). Research on mercury poisoning and bioaccumulation have resulted in national (e.g., Japan, Environmental Health and Safety Division [EHSD], 2013; US, Environmental Protection Agency [EPA], 2011) and international policies (Selin and Selin, 2006), and mercury warnings are prevalent in public health messaging worldwide.

While we may not be able to predict all such events, it is important to consider if and how we can build and restore necessary buffers that reduce the risk of adverse effects and enhance resilience ahead of time, as well as whether we can be more prepared during an event to opportunistically invest in strategies that reduce future risks to people and nature (see Q2.1, detailed below). This exercise also highlighted the critical role that mass-media, which developed during the 60 past years of our retrospective analysis, has played in the shaping of current social–ecological relationships. These influences include positive catalyzers, such as The Underwater World of Jacques Cousteau, which first brought the beauty of the underwater world into many homes, and the Blue Planet series, associated with the global movement to reduce plastic pollution. The documentary An Inconvenient Truth also raised public awareness of the dangers of climate change. On the negative side, however, the movie Jaws traumatized generations of humans and demonizing sharks, now threatened across the oceans, and Finding Nemo led to a global demand for clown fish in household aquaria that decimated the wild fish population along with their anemone host. Mass communication is likely to continue to be a major driver of change in human behaviors that affect marine ecosystems, likely in the form of social media or forms of mass communication yet to be developed, and require attention as powerful catalysts of change (see Q4.1, detailed below).

Priority Research

We identified 9 priority research areas and 46 research questions (Table 1). The priority research areas are: (1) ecological, individual, and cultural health; (2) crises as opportunities; (3) economics and financial incentives; (4) effective and inclusive communication; (5) ecological analyses; (6) governance; (7) technology and increased connectivity; (8) human behavioral change; and (9) food security. The questions we generated were predominantly multidisciplinary, highlighting that the potential for transformational change lies in meaningful engagement at the intersections of traditionally distinct disciplines and sectors. In this section, we detail eight questions consistently identified as high priority, providing a brief overview of current knowledge and potential impact of each. We refer readers to Table 1 to explore the full list of priority research questions. Highlighted questions are labeled with reference numbers used in Table 1, corresponding to their research area.

What does a healthy ocean look like under different world views? What are the key components of equity that affect diverse coastal communities, and how do they vary? Which interventions, in what contexts, provide the most benefit for people and nature? (Q1.1)

While the CBD highlights the importance of equity among stakeholders in conservation practice (CBD, 2010, 2011), there is limited evidence on how and in what situations equity interventions influence ocean health and conversely, how conservation initiatives affect equity. Examining common ocean sustainability interventions through an equity lens could shift the way interventions are envisioned and applied. General findings show that community stakeholder engagement is important for the success of conservation initiatives (Giakoumi et al., 2018), and outcomes are highly dependent on processes for participation (Reed, 2008; Sterling et al., 2017). “Equity” is a multidimensional issue, and multiple frameworks exist that describe differences in types of equity and how they may interface with conservation initiatives (Klein et al., 2015; Montambault et al., 2018). Critical knowledge gaps include: (1) how equity dynamics (types of equity issues, e.g., access equity, gender equity, generational equity; Klein et al., 2015) vary across different social and ecological contexts; (2) how different types of equity and conservation interventions affect the well-being of individuals and coastal ecosystems (e.g., Cinner et al., 2012a; Gurney et al., 2014); (3) what kinds of interventions are both appropriate and provide the greatest benefit to people and nature in diverse contexts (e.g., Castilla et al., 1998; Gelcich et al., 2008, 2012, 2015; Lubchenco et al., 2016); and (4) how issues such as access or distributional equity are affected by shifts in climate (Badjeck et al., 2010; Cinner et al., 2012b). Additional research in this area may evaluate the effectiveness of increased collaboration between conservation groups and organizations concerned with toxins, maritime-based human trafficking, food sovereignty movements, waste management, climate justice, and faith-based organizations (e.g., McLeod and Palmer, 2015).

Are women’s empowerment and increased engagement related to sustainable marine ecosystems and improved ocean management? If so, could the promotion of women’s empowerment and engagement improve ocean health? (Q1.3)

A key dimension of health and well-being in marine social–ecological systems is gender equity. Key research in this area includes whether and how gender equity relates to the long-term sustainable use and management of marine resources, as well as whether increased focus on gender equity promotes positive social and ecological consequences in coastal communities. Among the largest limitation in this research to date is the scarcity of gender disaggregated data across countries and domains (Monfort, 2015). Studies on the relationships between women’s access to marine resources, participation in marine resource governance, and ocean health are limited (Leisher et al., 2016; Kleiber et al., 2017; Gallardo-Fernández and Saunders, 2018; McLeod et al., 2018; Quimby and Levine, 2018); however, findings from these studies are emerging as critical issues in marine social–ecological systems especially in the context of climate change. Recent global analyses estimate that women comprise 47% of the workforce engaged in fishing and post-harvest operations, including in near-shore fisheries, gleaning, aquaculture, processing, trading, and financing of fisheries (Monfort, 2015; Kleiber et al., 2015). However, the degree and effects of women’s participation, or representation, in fisheries management have not been well described. Many resource users, including women, have ecological and traditional knowledge that can improve resource management; excluding women from management decision-making likely leads to managing with incomplete knowledge of the resource system and users (Agarwal, 2009; McLeod et al., 2018). In addition, greater participation by women in the decision-making process has been shown to increase compliance (Agarwal, 2009) and has the potential to support increased equity among resource users (Gallardo-Fernández and Saunders, 2018). Critically, there are increasing risks to health and livelihood among disenfranchised groups (often including women), as climate change increases the rate and intensity of natural disasters (Morioka, 2016; McLeod et al., 2018; Sorensen et al., 2018). Studies aimed at better understanding the role of women, as well as other disenfranchised groups, in sustainable resource management, as well as how to best promote more inclusive management will provide necessary insight toward the co-development of environmental and social strategies moving forward.

How do we use crises as opportunities to reduce future risks to people and nature? (Q2.1)

Crises often present opportunities to transform systems of resource use and management (Folke et al., 2010). Critical coastal management decisions are made during the phases of response, recovery, planning, and mitigation that follow crises, and these decisions can result in permanent changes in policy or agency structure. For example, the formation of the EPA and passage of the RESTORE Act followed pollution crises of considerable magnitude in the United States during the 1960s. Following such events, long-standing policies on risk and coastal management are often re-considered, and millions to billions of dollars are spent on recovery, re-building, and restoration. Rapid decision making can have profoundly negative or positive impacts on the long-term resilience of coastal and marine ecosystems and the people who depend on them. For example, while Hurricane Sandy inspired increased interest in improving coastal resilience, only ∼1% of recovery funding was used for building natural coastal resilience (e.g., wetland restoration; Barbier, 2015), representing a missed opportunity. By contrast, the Indian Ocean Tsunami of 2004 provided evidence of the protective role of mangroves against extreme events impacting on coastal areas, leading to major restoration efforts in the region (Barbier, 2006). Research shows natural, “green,” solutions achieve a consistently greater cost–benefit ratio compared to most gray infrastructure solutions (Reguero et al., 2018) and can provide a significant reduction in total economic risk (Narayan et al., 2017; Beck et al., 2018). The recovery phase is an important period to provide sound scientific advice and achieve long-lasting progress toward increased resilience and sustainability. However, doing so requires a vision for the changes we would like to see in policy and practice, strong collaborations that can be rapidly enacted post-event, and identification of appropriate lessons that can be applied to increase the resilience of coastal social-ecosystems.

Does media catalyze change in policies and actions that impact global ocean health, and if so, how? (Q4.1)

The role of advertising in driving behavioral change is well researched (reviewed in Stewart et al., 2002). However, the effective use of media to promote environmental action is less understood. For instance, why did a video of a turtle with a straw embedded in its nose inspire widespread public action to ban plastic straws, while many other information campaigns elicit little response? Environmental action may relate in some ways to well-researched effects such as priming intensity (Roskos-Ewoldsen et al., 2009), interpersonal communication following media consumption (ibid), or trust in the media source (Stewart et al., 2002). However, it is also possible that environmental action results from different kinds or subsets of communication strategies than those that inspire consumptive or political action. Marketing professionals integrate findings from the field of psychology to develop advertisements (e.g., to sell toothpaste). How is the psychology of motivating environmental behavior and policy change, specifically in relation to the ocean, different from that of marketing products? While many theories have been proposed in the field of environmental psychology, no definitive answers have been found regarding consistent drivers of pro-environmental behavior (Kollmuss and Agyeman, 2002). The “information deficit” model, which assumes environmental education will lead directly to environmental action, has been demonstrated repeatedly to be ineffective at generating widespread behavior change, but it remains a dominant strategy used in public campaigns by NGOs and governments (ibid). Research into social behavioral drivers has shown that perceived social norms can influence environmental behavior; for instance, Schultz et al. (2007) found that consumers changed their electricity consumption when they received normative feedback about how their consumption compared to that of their neighbors. Finally, in the same way that the broad integration of television in the 1950s and ’60s ushered in a new era of sharing news, entertainment, and educational programming, the upheaval in social and other media now could present an opportunity for immediate action, transforming the way scientists, practitioners, and the general public collaborate. However, competition for the attention of global audiences may lead media to spin headlines regarding research reports on the status of the ocean, consolidating a negative perception beyond that supported by evidence, and drawing the public to inaction (Duarte et al., 2014). How can these new forms of media be most effectively used to inspire positive environmental action?

How do different people/societies/cultures/sectors define an aspirational ocean future? Is there an emergent shared vision? (Q4.2)

A quantitative analysis of how cultural and societal factors affect “visions” for a healthy future ocean would contribute toward culturally relevant conservation strategies and metrics for measuring conservation success. Research on values of coastal ecosystems has been criticized for prioritizing economic values and for ignoring intrinsic and cultural values as motivation for conservation action (Chan et al., 2012b). For example, stewardship of nature is valued in many religions, and may be well-aligned with conservation objectives (Bhagwat et al., 2011). Sacred natural sites are often affiliated with increased endemic biodiversity, old growth forests, and rare species (Dudley et al., 2010). While diverse cultural values and practices may lead to conservation outcomes, they may differ substantially from mainstream conservation practices and may not be recognized by conservation initiatives or higher levels of governance (Govan and Jupiter, 2013; Jupiter, 2017). Once these dimensions are better understood, groups spanning multiple scales and contexts (e.g., collaborations among governments, communities, conservation groups, social well-being, and sustainable development organizations) could work to define best practices for promoting social and ecological well-being within the context of a particular worldview. On an international level, this could lead to developing policy and support for diverse solutions. This research could also inform future scenarios used by groups such as IPCC (e.g., Rogelj et al., 2018) that do not currently include diverse views of future human–ecological relationships.

In what ways do different governance systems (formal and informal) respond and adapt to change? Which governance systems, under what conditions, have resulted in tangible changes in ocean management? What are the most effective structures of governance for promoting community health, resilience, and sustainable ecosystems? (Global, state, local?) (Q6.1)

Various studies have examined the efficacy of fisheries management regimes, including impacts and outcomes of marine protected areas (MPAs), Territorial Use Rights Fisheries (TURFs), catch shares or catch limits, co-management, and gear restrictions (e.g., Halpern, 2003; Mascia et al., 2010; Cinner et al., 2012a; Edgar et al., 2014; d’Armengol et al., 2018; Gelcich et al., 2019). However, this research has rarely considered the question of how different governance structures respond and adapt to significant ecological change. What systems of governance are most effective for sustainable management of fisheries and other ocean-based resources across ecological and social contexts? Answering these questions requires identifying the governance context and strategies that have been employed in the face of significant ecological changes in the past to explore how different governing and management systems have, or have not, been resilient to fundamental changes due to past trends and events.

How would providing observation at revolutionary scale impact effective marine conservation? (Q7.2)

Many current ocean observation systems are sporadic and aimed at individual products. Even examples of large efforts sustained by governments (e.g., fisheries trawl surveys stretching over 50 years) are episodic, conducting surveys one or two times a year, in heavily fished areas, at a finite number of points. Such constraints impose management and conservation challenges that could be reduced with observing technology. However, advances in ocean robotics, emerging global efforts in observation (e.g., the Global Ocean Observation System, Lindstrom et al., 2012), and the development of several national and international initiatives (including the UN Decade on Ocean Science) highlight the present as a critical moment for the development and use of increased monitoring for scientific discovery, environmental analysis, and informing policy across scales (Visbeck, 2018; Claudet et al., 2020). The impact of a big-data approach to ocean observation is emerging through products recently derived from access to Automatic Identification System (AIS). For the first time, these have allowed the mapping of global fishing activity and quantification of use of the High Seas¹ (McCauley et al., 2016), among other applications. The data generated by this technology, however, is accessible only by fee, and while massive in scale it must be expanded, as it currently encompasses only 50–70% of the global fishing fleet. More pervasive ocean observation could permit more dynamic, responsive, and predictive classification of MPAs, to support movement of protected areas relative to habitat, migratory species, climate change, and other requirements (e.g., Tommasi et al., 2017). Long-term and high-resolution datasets can be used globally to better understand patterns and processes in the ocean, and to promote sustainable management of resources, including in response to shifts in the phenology of marine systems (Hazen et al., 2018; Hays et al., 2019). They also can improve evaluation of ongoing efforts by providing metadata and documentation on project design and metrics of success and failure, as well as facilitate the development of predictive models for assessing climate change impacts at ecologically relevant scales (Rilov et al., 2019). Furthermore, greater access to information on the use of open oceans and exclusive economic zone intrusions will help to quantify and manage use. The potential payoff of new ocean observing capacity stretches beyond these examples to, more generally, anticipatory and real-time rather than reactionary decision making across a range of marine resource issues (Maxwell et al., 2015).

Where and in what do we invest to ensure sustainable, just, culturally appropriate, and nutritious food for the all people? What are the positive and negative outcomes of including seafood and aquaculture in human diets? (Q9.1)

As we work toward a sustainable and just future, meeting the nutrition demands for a rapidly growing global population (United Nations Department of Economic and Social Affairs Population Division, 2017) will require culturally appropriate solutions that are robust to increasing environmental and economic shocks to food systems (Cottrell et al., 2019). Achieving this goal requires better understanding of the ecological and social linkages between food systems to properly assess synergies, trade-offs, and vulnerabilities (Halpern et al., 2019). Further research is required to assess the ecological and human health trade-offs associated with different food sources and diets (Tilman and Clark, 2014; Davis et al., 2016), as well as the costs and benefits of increased trade across different regions and cultures (Puma et al., 2015), including issues of justice and equity in the export of luxury protein (e.g., shrimp/prawns) from protein-deficient to protein-rich societies. In addition to traditional agricultural crops, livestock, and fisheries, marine aquaculture is increasing, and has enormous potential to increase access to nutritionally rich seafood and create jobs while modulating the demand that drives issues such as overfishing (e.g., Gentry et al., 2017). However, ecological consequences must be accounted for in order for aquaculture to be sustainable (e.g., Froehlich et al., 2018a). Devising pathways for sustainable aquaculture production and evaluating the limiting factors is fundamental to manage expectations on the role that aquaculture should play in sustainably delivering healthy food contributing to the well-being of a growing human population. Other novel alternatives include the development of cellular agriculture (“lab meat”) (Stephens et al., 2018) and seafood (“clean seafood”). All solutions, whether traditional or novel, have different potential for innovation and adoption, and dynamics between production mechanisms, demand, equity, trade pathways, and ecological relationships require further research.

Discussion of the Process and Findings

While horizon scanning exercises have been conducted for global conservation issues (e.g., Sutherland et al., 2018), few have specifically considered issues facing marine social–ecological systems. Furthermore, those horizon-scanning exercises were focused on current research needs rather than the research needed to prepare for future pressures, anticipated and not. Those that have focused on the marine environment (Heip et al., 2011; Fissel et al., 2012; Parsons et al., 2014; Rudd, 2014) have included few, if any, contributors outside the environmental sciences. In this study, we engaged a broad set of experts to identify critical research needed to radically improve human wellbeing and ecosystem health over the next 30 plus years. This likely contributed to the more multidisciplinary nature of the questions and themes than have arisen in traditional horizon scanning exercises, and a greater balance between the focus on natural and social sciences in framing and developing the questions. However, we note that other studies (ibid), despite engaging less diverse groups, have identified social–ecological questions as priority research areas. We also recognize that our efforts toward diverse inclusion could have been broader, e.g., by engaging indigenous peoples and greater geographic diversity, including more representatives of developing countries. The incorporation of these perspectives would generate additional important questions, and we hope that future efforts will continue to improve in this regard.

The primary question posed to the working group as well as preliminary exercises oriented our group toward issues contextualized by climate change. We believe this was an appropriate and realistic contextualization of scientific questions aimed at long-term impacts across social and ecological boundaries. However, this future-focused lens likely minimized questions that may have focused on tensions between immediate processes and needs. Additionally, while our focus was on marine systems, many of the research questions identified are likely relevant in other types of social–ecological systems.

Accomplishing global targets for climate change mitigation, marine conservation, human well-being, and sustainable development (e.g., Paris Agreement, United Nations SDGs, Aichi Biodiversity Targets) requires multidisciplinary and cross-sector research and collaboration (Hallegatte and Mach, 2016; Claudet et al., 2020). The list of priority research questions identified here would, if addressed, contribute important research toward achieving these global initiatives far into the future. For instance, priority research area 1 (“Ecological, individual, and cultural health”) includes questions related to SDG-2 (zero hunger), SDG-3 (good health and well-being), SDG-10 (reduced inequalities), and SDG-13 (climate action), as well as SDG-14 (ocean sustainability) (United Nations, 2015). Many of our questions also align with the Aichi Biodiversity Targets (CBD, 2010), especially Targets 4, 6, 7, 11, and 14–16, and with Articles 6–7 of the Paris Agreement (United Nations Framework Convention on Climate Change [UNFCCC], 2015). Several research questions, especially those in priority research areas 3 (“Economics and financial incentives”) and 7 (“Technology and increased connectivity”) would also contribute valuable information toward evaluating and implementing the World Bank’s “Blue Economy” initiative (World Bank and United Nations Department of Economic and Social Affairs, 2017), as well as SDG-7 (United Nations, 2015). Finally, many identified questions are well-aligned to the United Nations Decade of Ocean Science for Sustainable Development (2021–2030). In addition to their contribution to these initiatives, all questions identified in this study strive toward a common goal of achieving the best possible ocean future.

We firmly support the continuation of such cross-sector collaborations, both in determining research objectives, as well as in carrying out studies and working toward solutions. In fact, global initiatives such as the SDGs provide a framework to interface across organizations, including those working on issues of justice, but who hold to a more anthropocentric worldview. However, the current infrastructure of funding and institutional support for collaborations across institutions and sectors is lacking. Supporting cross-sector collaborations among management organizations, non-profits, and academic institutions requires increased institutional support. Particularly useful mechanisms include increased support for boundary organizations, increased funding opportunities for coproduction (for example, those that currently require conservation organizations to work with development agencies in proposals), increased recognition for participation in coproduction groups (e.g., in academic tenure review), increased training in effective coproduction, and building the cultural competency to work across sectors (Reich and Reich, 2006; Cook et al., 2013; Beier et al., 2017). We emphasize that cross-sector collaborations are fundamental to tackling interlinked global issues at relevant scales and time-course.

We believe the questions presented here are exemplary of the kinds of cross-sector research agendas required to confront the challenges facing marine social–ecological systems. We hope that funding organizations and research groups will take up these questions as priorities as we move together toward a healthy and just future for ourselves and our oceans.
