State of science: refitting the human to nature.

Environmental institutions are realising that the human-nature relationship is a tangible target for a sustainable future. Societal change of that relationship is a challenge involving modifications to both systems and human behaviours. We argue that as Human Factors and Ergonomics (HFE) focusses on relationships, interfaces and systems it is well placed to contribute. After introducing the state of HFE and nature connectedness science an analysis of areas of HFE and human-nature connectedness themes is used to consider current work and future opportunities. We conclude that despite decades-old calls to action, HFE is embedded in a dated paradigm and has had little positive contribution to the human-nature relationship. However, HFE is well placed to create sustainable communities, designed to create a new relationship with nature. To do this, HFE needs to recognise that it should move on from solely fitting the task to the human, to refitting the human to nature.Practitioner Summary: A more sustainable human-nature relationship can be achieved through applying HFE approaches. HFE expertise in human characteristics, systems, people and technology can be applied at differing scales with various social-economic and technical factors to address key themes in our failing relationship with nature.Abbreviations: HFE: Human Factors and Ergonomics; IPBES: Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services; STAMP: System-Theoretic Accident Model and Processes; CWA: Cognitive Work Analysis; NET-HARMS: NETworked Hazard Analysis and Risk Management System; NbS: Nature-based System.

Actionable insights for human factors and ergonomics to achieve the Sustainable Development Goals: mapping past advancements and proposing future strategic paths.

Despite significant strides in linking Human Factors and Ergonomics (HFE) and sustainability, research lacks precision in debating HFE's role, especially concerning the Sustainable Development Goals (SDGs). This paper maps concrete contributions of HFE to the SDGs, offering strategic actions for target achievement. The methodological approach involved the application of PRISMA to define a sample, SciMAT and VOSviewer for visual and temporal thematic mapping, deductive content analysis and categorical analysis. The results show that there is an already rich and unique set of contributions across a wide range of SDGs, not just the most common related to HFE, SDG8 (Decent work). The importance of HFE is highlighted in various aspects, such as the sustainable adoption of industry 4.0 technologies (SDG9) and the development of sustainable production (SDG12), energy (SDG7) and urban (SDG11) systems. Strategic actions specifying targets for each mapped SDG are offered for policymakers, industry professionals and researchers.

This paper maps concrete contributions of HFE to the SDGs, including aspects such as sustainable adoption of industry 4.0 technologies and the development of sustainable production, energy and urban systems. Policymakers, industry professionals and researchers can benefit from the strategic pathways offered to further advance the SDGs.

Contribution of ergonomics and human factors to sustainable development: a systematic literature review.

Although a significant amount of research has already been published, the field of ergonomics/human factors and sustainability (E/HF-S) has not yet been systematically profiled based on recent studies. Conducting a systematic review of the literature, this article aims: (i) to identify the main emergent research themes in this subject area and (ii) to provide future directions for applied research and practice on E/HF-S. Six emergent research themes were identified in this literature allowing for a proposal to synthesise the main concepts related to E/HF-S. However, it was noted that there are still relatively few empirical papers which assess the models being developed or that apply E/HF principles to sustainability challenges. Thus, this paper identifies the opportunities for practical application related to E/HF-S. The last part of the paper explores the E/HF-S opportunities using an external framework; the United Nations' sustainable development goals.Practitioner summary: The field of ergonomics/human factors and sustainability (E/HF-S) has not yet been organised by recent studies. Conducting a systematic review of the literature, this article identifies the main emergent research themes in this subject area, and it provides future direction for applied research and practice on E/HF-S.Abbreviations: ACE: activity-centred ergonomics; E/HF: ergonomics/human factors; E/HFS: ergonomics/human factors and sustainability; IEA: International Ergonomics Association; PRISMA: Preferred Reporting Items for Systematic Reviews and Meta-Analyses; SDG: Sustainable Development Goal.

Affective and cognitive restoration: comparing the restorative role of indoor plants and guided meditation.

This study investigated whether indoor plants were as effective as a guided meditation for enabling psychological recovery after fatigue induced by the abbreviated vigilance task. Sixty students were randomly assigned to an indoor plant, guided meditation, or control rest-break condition. The psychological processes most in need of recovery were identified as cognitive and affective restoration. Measures of affect, stress, and working memory were taken before and after the vigilance task, and again after a rest intervention. The vigilance task-induced fatigue as shown by a significant vigilance decrement and also significantly lowered positive affect and cognitive engagement, and significantly increased distress across all three conditions. After exposure to the break interventions, distress significantly decreased for participants in the indoor plant break condition while distress significantly decreased and engagement significantly increased in the guided meditation break condition. Indoor plants and guided meditation had a small, but significant positive impact on affective restoration and no significant impact on cognitive restoration. Practitioner summary: Indoor plants are a cost-effective green ergonomics intervention in offices. This study found that a rest break with indoor plants was as effective as a rest break with guided meditation for affective restoration after fatigue from a vigilance task.AbbreviationsARTattention restoration theoryLCDliquid crystal displayPANASpositive and negative affect scheduleDSSQS: dundee stress state questionnaire - short versionBDSbackward digit spanANOVAanalysis of varianceCIconfidence intervalMmean.

Applying the sustainable system-of-systems framework: wastewater(s) in a rapidly urbanising South African settlement.

Addressing wastewater infrastructure needs in urban informal settlements must simultaneously address legacies of past failures, current aspirations and constraints, as well as increasingly changing needs related to global environmental change. This study applied the Sustainable System-of-Systems framework for ergonomics and human factors to gain a better understanding of how small in-situ constructed wetlands could be a form of greywater treatment infrastructure in an informal settlement. Using 24 months of interviews, surveys, workshops and photo-ethnographic observations, we identified that the rapidly changing nature of parent (e.g. residency transience and land ownership) and sibling (e.g. housing and drinking water) systems put pressure on the target wetland system to adapt, often decreasing its capacity to deliver the service of water cleaning. Greywater treatment was not a common goal among stakeholders involved in the nested hierarchy system which likely contributed to the constructed wetlands needing to adapt to remain relevant.Practitioner summary: The value of the Sustainable Systems-of-Systems framework for ergonomics/human factors professionals in determining the sustainability of an ergonomics/human factors intervention is demonstrated using a greywater treatment system case study for an urban informal settlement. Understanding the variety of stakeholder goals and the pace of change in related systems was key to a sustainable intervention.

Understanding the Links Between Climate Change Risk Perceptions and the Action Response to Inform Climate Services Interventions.

Understanding what motivates people to act on climate change provides an opportunity to design more effective interventions, in particular, climate services interventions, by aligning them with factors that strongly influence action. Climate change risk perceptions have been shown to underlie action on climate change. Therefore, this study performs exploratory research to understand how various determinants of risk perceptions contribute and interact to influence climate change risk perceptions and professional action on climate change in East Africa, in order to inform the context-specific design of climate services. Using data collected through a region-wide survey, a model to risk perceptions and professional action was constructed through structural equation modeling. The model elucidates the cascading effects of variables such as age, gender, education, and personal values on action. In particular, it highlights a split in motivating factors among individuals with higher levels of self-enhancing values versus those with higher levels of self-transcending values. The model also highlights the prominent role that experience of extreme weather events, psychological proximity of climate change, climate change risk perceptions, and social norms play in motivating action. The model, therefore, offers a framework for prioritizing the various factors that motivate people to take adaptation action, which, in turn, provides a basis for informing climate services development going forward.

Human factors and ergonomics systems-based tools for understanding and addressing global problems of the twenty-first century.

Sustainability is a systems problem with humans as integral elements of the system. However, sustainability problems usually have a broader scope than socio-technical systems and therefore, require additional considerations. This requires a fuller integration of complex systems understanding into the systems analysis toolset currently available to human factors and ergonomics. In this paper, we outline these complex systems requirements necessary to tackle global problems such as sustainability and then assess how three common systems analysis tools (i.e. Accimap, System Theoretic Accident Mapping and Processes, and Cognitive Work Analysis) stand up against these revised criteria. This assessment is then further explored through applying two of these tools (i.e. Accimap and System Theoretic Accident Mapping and Processes) to a transnational food integrity system problem. This case study shows that no single systems analysis method can be used in isolation to help identify key insights for intervention and that new methods may need to be developed or existing methods need to be adapted to understand these dynamic, adaptive systems. The implications for the further development of systems analysis tools are discussed. Practitioner summary: We assess the applicability of existing human factors and ergonomics systems-analysis tools for examining global problems and for identifying points to intervene in these systems. We comment on what extensions and further work will be required to enable human factors and ergonomics to intervene effectively.

State of Science: ergonomics and global issues.

In his 1993 IEA keynote address, Neville Moray urged the ergonomics discipline to face up to the global problems facing humanity and consider how ergonomics might help find some of the solutions. In this State of Science article we critically evaluate what the ergonomics discipline has achieved in the last two and a half decades to help create a secure future for humanity. Moray's challenges for ergonomics included deriving a value structure that moves us beyond a Westernised view of worker-organisation-technology fit, taking a multidisciplinary approach which engages with other social and biological sciences, considering the gross cross-cultural factors that determine how different societies function, paying more attention to mindful consumption, and embracing the complexity of our interconnected world. This article takes a socio-historical approach by considering the factors that influence what has been achieved since Moray's keynote address. We conclude with our own set of predictions for the future and priorities for addressing the challenges that we are likely to face. Practitioner Summary: We critically reflect on what has been achieved by the ergonomics profession in addressing the global challenges raised by Moray's 1993 keynote address to the International Ergonomics Association. Apart from healthcare, the response has largely been weak and disorganised. We make suggestions for priority research and practice that is required to facilitate a sustainable future for humanity.

A sustainable system of systems approach: a new HFE paradigm.

Sustainability issues such as natural resource depletion, pollution and poor working conditions have no geographical boundaries in our interconnected world. To address these issues requires a paradigm shift within human factors and ergonomics (HFE), to think beyond a bounded, linear model understanding towards a broader systems framework. For this reason, we introduce a sustainable system of systems model that integrates the current hierarchical conceptualisation of possible interventions (i.e., micro-, meso- and macro-ergonomics) with important concepts from the sustainability literature, including the triple bottom line approach and the notion of time frames. Two practical examples from the HFE literature are presented to illustrate the model. The implications of this paradigm shift for HFE researchers and practitioners are discussed and include the long-term sustainability of the HFE community and comprehensive solutions to problems that consider the emergent issues that arise from this interconnected world. PRACTITIONER SUMMARY: A sustainable world requires a broader systems thinking than that which currently exists in ergonomics. This study proposes a sustainable system of systems model that incorporates ideas from the ecological sciences, notably a nested hierarchy of systems and a hierarchical time dimension. The implications for sustainable design and the sustainability of the HFE community are considered.

Towards a sustainable world through human factors and ergonomics: it is all about values.

In this paper, we analyse two approaches that attempt to address how a human factors and ergonomics (HFE) perspective can contribute to the sustainability of the human race. We outline the principles, purposes and fields of application of ergoecology and green ergonomics, and thereafter deal with their context of emergence, and the overlaps in purpose, and principles. Shared values are deduced and related to socio-technical principles for systems' design. Social responsibility and environmental/ecospheric responsibility are the leading threads of ergoecology and green ergonomics, giving rise to the values of: respect for human rights, respect for the Earth, respect for ethical decision-making, appreciation of complexity, respect for transparency and openness, and respect for diversity. We discuss the consequences of considering these values in HFE theory and practice.

Modelling associations between mortality salience, environmental concerns, and climate change risk perception in the context of the pandemic.

The pandemic and climate change are mortality salience triggers. Environmental issues, attitudes, and climate change risk perceptions were hypothesised to impact how individuals perceived the threat of COVID-19 and climate change during the pandemic. The study explored: 1.) the associations between seeing a link between COVID-19 and climate change and environmental concerns; 2.) the associations between mortality salience and environmental concerns; 3.) the associations between feeling less worried during the pandemic and environmental concerns; and 4.) what these associations tell us about the relationship between mortality salience, the perceived link between COVID-19 and climate change, and feeling less worried during the pandemic. A sample of 665 respondents was achieved from an online survey in 2021. The results of the multiple regression analysis and structural equation modelling showed that environmental issues, attitudes and perceptions, time spent in nature, and climate change risk perception played a role in the extent to which individuals perceived COVID-19 as an indicator of climate change threats, whether mortality salience was made conscious, and whether there was distancing of concern about climate change and social issues during the pandemic. The study makes an important contribution to understanding psychological processes that are activated during disasters that trigger mortality salience, and how this is impacted by the human-nature nexus, and climate change risk perception.

Green ergonomics: definition and scope.

This paper demonstrates that the goals of ergonomics (i.e. effectiveness, efficiency, health, safety and usability) are closely aligned with the goals of design for environmental sustainability. In this paper, the term 'green ergonomics' is conceptualised to specifically describe ergonomics interventions with a pro-nature emphasis. Green ergonomics is focused on the bi-directional connections between human systems and nature. This involves looking at (1) how ergonomics design and evaluation might be used to conserve, preserve, and restore nature and (2) how ecosystem services might be harnessed to facilitate the improved wellbeing and effectiveness of human systems. The paper proposes the scope of green ergonomics based on these bi-directional relationships in the areas of the design of low resource systems and products, the design of green jobs, and the design for behaviour change. Suggestions for further work in the green ergonomics domain are also made. PRACTITIONER SUMMARY: Given the enormous environmental challenges facing modern industrial society, this paper encourages ergonomics science to embrace a pro-nature understanding of work design and research. This paper sets out the role for green ergonomics based on an appreciation of the human-nature connections that have been integrated with our understanding of ergonomics science and practice.

Exploring the impact of the pandemic on the relationship between individual types and the natural environment: the role of mortality concerns.

COVID-19 is a global event that has impacted every individual on earth in some way and can be viewed as a mortality salience trigger. Although there were reports of increased nature exposure across the world, research is needed to understand whether the pandemic event impacted the underlying psychology of the human-nature nexus. Given the likelihood of pandemics and environmental challenges increasing in frequency in the future, there is a need for a deeper understanding of how pandemics impact individuals' relationship with the natural environment in South Africa. To achieve this, the study applied psychological types (grouping individuals based on homogeneity) to explore potential shifts as human nature is neither fixed, nor universal. The study asked: Given the multiple significant impacts of COVID-19 on the African continent, how have perceptions and attitudes towards the natural environment changed within and between types of individuals from 2016 (pre COVID) to 2021 (COVID) in South Africa? In a longitudinal, quantitative study, separate samples 721 in 2016 and 665 in 2021 were obtained. Participants in 2021 were grouped into the same six types using the same criteria, for comparison with the 2016 data. The results showed limited potential for pandemics to act as catalysts for long-term individual change towards increased pro-environmentalism. The study confirmed the main tenets of Terror Management Theory that individuals tend to be driven to uphold worldviews when confronted with mortality. Furthermore, there was a reduced experience of personal control over outcomes that increased reliance on sources of control outside the self as an attempt to buffer against mortality concerns. The study contributes towards Terror Management Theory's application during pandemics, and how that relates to individual environmental attitudes and perceptions.

Past, present, and future of E/HF for sustainability: A perspective from the HFSD Technical Committee.

BACKGROUND: Sustainability is a highly important theme worldwide and currently is being tackled by almost all disciplines. Indeed, the future of humanity is dependent on the actions taken now and in the immediate future. The Ergonomics and Human Factors (E/HF) community has not been indifferent to this issue, and one of the concrete actions adopted by the International Ergonomics Association (IEA) was the establishment of the "Human Factors for Sustainable Development" (HFSD) Technical Committee. OBJECTIVE: To identify future paths of action, this paper recognizes the trajectory of the HFSD Technical Committee, summarizes the contributions presented at IEA2021, the International Congress on Ergonomics held virtually in Vancouver in 2021, and reflects on key aspects that should be boosted by the Technical Committee. METHODS: This is a qualitative interpretative study that reflects on the contributions of members of the HFSD community working on E/HF for sustainability. RESULTS: Central topics and opportunities in E/HF and sustainability include complexity of systems, behaviors, and work; energy use and consumption; co-design, interconnectivity, territories, and the relationships with stakeholders. CONCLUSION: Although the contributions have been growing, there is still a lot of work needed, both theoretically and practically. Themes to be discussed include the concepts of sustainability and work. Considering the centrality of human beings (i.e., decision making for achieving the different dimensions of sustainability), the authors identify a set of values as core principles for leading the discussion.

Central afferents to the nucleus of the solitary tract in rats and mice.

The nucleus of the solitary tract (NTS) regulates life-sustaining functions ranging from appetite and digestion to heart rate and breathing. It is also the brain's primary sensory nucleus for visceral sensations relevant to symptoms in medical and psychiatric disorders. To better understand which neurons may exert top-down control over the NTS, here we provide a brain-wide map of all neurons that project axons directly to the caudal, viscerosensory NTS, focusing on a medial subregion with aldosterone-sensitive HSD2 neurons. Injecting an axonal tracer (cholera toxin b) into the NTS produces a similar pattern of retrograde labeling in rats and mice. The paraventricular hypothalamic nucleus (PVH), lateral hypothalamic area, and central nucleus of the amygdala (CeA) contain the densest concentrations of NTS-projecting neurons. PVH afferents are glutamatergic (express Slc17a6/Vglut2) and are distinct from neuroendocrine PVH neurons. CeA afferents are GABAergic (express Slc32a1/Vgat) and are distributed largely in the medial CeA subdivision. Other retrogradely labeled neurons are located in a variety of brain regions, including the cerebral cortex (insular and infralimbic areas), bed nucleus of the stria terminalis, periaqueductal gray, Barrington's nucleus, Kölliker-Fuse nucleus, hindbrain reticular formation, and rostral NTS. Similar patterns of retrograde labeling result from tracer injections into different NTS subdivisions, with dual retrograde tracing revealing that many afferent neurons project axon collaterals to both the lateral and medial NTS subdivisions. This information provides a roadmap for studying descending axonal projections that may influence visceromotor systems and visceral "mind-body" symptoms.

Agency and Bandura's Model of Triadic Reciprocal Causation: An Exploratory Mobility Study Among Metrorail Commuters in the Western Cape, South Africa.

Most studies on sustainable mobility focus on technological, socio-structural, or psychosocial influences while neglecting individual motivations and practices. In this study, we examine mobility motivations and practices as part of a complex interplay between psychosocial and socio-structural dimensions within the mobility infrastructure of Metrorail in the Western Cape. Drawing on Albert Bandura's theory of personal agency and the model of triadic reciprocal causation, we interviewed 38 commuters (mean age 33 years, SD 11, 50% women/men) and analyzed the data using hermeneutic content analysis and multidimensional scaling. Based on our analyses, we identified three pathways that describe the mobility practices of Metrorail users, each with its own purpose and function. We explore these pathways and their consequences for sustainable mobility in relation to daily commuter agency, motivations, and past experiences.

Mental models of a water management system in a green building.

This intergroup case study compared users' mental models with an expert design model of a water management system in a green building. The system incorporates a constructed wetland component and a rainwater collection pond that together recycle water for re-use in the building and its surroundings. The sample consisted of five building occupants and the cleaner (6 users) and two experts who were involved with the design of the water management system. Users' mental model descriptions and the experts' design model were derived from in-depth interviews combined with self-constructed (and verified) diagrams. Findings from the study suggest that there is considerable variability in the user mental models that could impact the efficient functioning of the water management system. Recommendations for improvements are discussed.

Human factors for a sustainable future.

Current human activities are seriously eroding the ability of natural and social systems to cope. Clearly we cannot continue along our current path without seriously damaging our own ability to survive as a species. This problem is usually framed as one of sustainability. As concerned professionals, citizens, and humans there is a strong collective will to address what we see as a failure to protect the natural and social environments that supports us. While acknowledging that we cannot do this alone, human factors and ergonomics needs to apply its relevant skills and knowledge to assist where it can in addressing the commonly identified problem areas. These problems include pollution, climate change, renewable energy, land transformation, and social unrest amongst numerous other emerging global problems. The issue of sustainability raises two fundamental questions for human factors and ergonomics: which system requires sustaining and what length of time is considered sustainable? In this paper we apply Wilson (2014) parent-sibling-child model to understanding what is required of an HFE sustainability response. This model is used to frame the papers that appear in this Special Issue.
