“Climate, Psychology and Change” offers a profound exploration of the psychological ramifications of the climate and ecological emergency (CEE), proposing a paradigm shift in psychotherapy to better support individuals and communities grappling with environmental distress. The book critiques the prevailing hyper-individualized and neoliberal societal framework, advocating for a decolonized, systemic psychotherapeutic approach that emphasizes interconnectedness across species and that challenges human exceptionalism. It outlines four psychological phases that individuals may experience in their environmental consciousness journey, epiphany, immersion, crisis, and resolution, highlighting their non-linear and systemic nature. This work underscores the importance of understanding distress within its broader social and ecological contexts and addresses the profound inequalities and injustices exacerbated by the CEE. With contributions from diverse psychological and non-traditional backgrounds, it introduces concepts like ‘ubuntu’, advocating for community-focused resilience practices. The book calls for a re-evaluation of psychotherapeutic practices to include communal and nature-connected approaches, offering innovative solutions like climate cafes and social dreaming. It presents a critical yet hopeful vision for the role of psychotherapy in navigating the challenges of the CEE, urging a rethinking of our relationship with the planet and each other, making it an essential read for those seeking to align psychotherapeutic practice with the realities of our changing world.

Food systems are complex and multifaceted, comprising a diverse range of actors, processes, and interactions. Participatory system mapping can be employed to help understand this complexity and support the development of sustainable and resilient food systems. This article shares a participatory mapping approach that has been developed as part of the Climate–Biodiversity–Health (CBH) Nexus project in the Comox Valley, British Columbia, Canada. This research pursues two main aims: (1) to ground truth in the CBH system map of food systems, developed with the participation of stakeholders; and (2) to explain how participatory system mapping can be employed to clarify the complexity of food systems in a clear and concise manner for all stakeholders. This research contributes to the literature on participatory system mapping, including critiques of its practical utility, by employing participatory approaches to visualize multi-dimensional and multi-level system maps with an emphasis on verifying that they are clear, understandable/useful, and reliable for diverse stakeholder audiences.

Food insecurity is an economic and social condition that involves individuals having limited or uncertain access to healthy food. Despite the well-intentioned efforts of both governmental and not-for-profit organizations in addressing food insecurity, well over one-in-ten households in the U.S., the wealthiest nation in the world, experience food insecurity every year. The objective of this literature review was to identify and explicate the methods and outcomes of food insecurity interventions that have been conducted among U.S. adults. This literature review identified 38 studies detailing several government programs and research interventions designed to address food insecurity. Results from the review highlight how the Supplemental Nutrition Assistance Program (SNAP), The Emergency Food Assistance Program (TEFAP), and not-for-profit food banks have demonstrated success in improving food insecurity. However, the prevalence of food insecurity among U.S. households has fluctuated without any sustained decreases that achieve a food insecurity rate that remains below 10 percent of the population. Food waste, which refers to food that is edible yet discarded at the retail or consumption phases, is rampant in the U.S., as approximately 30 percent (66.5 million tons) of edible food is wasted after leaving the farm every year. Food waste prevention efforts that involve rescuing edible, nutritious food and redistributing it to individuals who are food insecure can promote both environmental wellbeing and public health through simultaneous reductions in food waste and food insecurity.

Given the effect of urbanization on land use and the allocation and implementation of urban green spaces, this paper attempts to analyze the distribution and accessibility of public parks in India’s Bengaluru city (previously known as Bangalore). Availability, accessibility, and utilization—the key measures of Urban Green Spaces (UGS)—are mostly used in health research and policy and are important components of Planetary Health Equity in the context of studying UGSs and health. A geo-spatial method was used for mapping the park’s distribution and measuring its accessibility, using road network data. To understand equitable access to the parks, four socio-economic parameters—population density, the percentage of the population below 6 years of age, the proxy wealth index, and scheduled caste population—were correlated with the parks’ accessibility. This spatial distribution revealed that 19 of 198 wards did not have a single park and that 36 wards only had one park. About 25–29% of wards did not have accessibility to neighborhood-level and community-level parks within a 400–800 m distance. These parks must be accessible within a walking distance of 400–800 m but were found to most likely be inaccessible on the periphery of the city where the population density is low and the children population is high, in comparison to the central part of the city. Similarly, parks were found to be inaccessible in the eastern part of the city where the scheduled caste population is high and also found to be inaccessible for the low-income neighborhoods residing in the western part and southern periphery of the city, indicating the uneven distribution of and inequitable access to public parks. Our study proposes a reshaping of both neighborhood parks and community parks in an attempt to look beyond biodiversity, through the planetary health equity approach, by noting that, while biodiversity indirectly has a positive effect on health, public parks should not only be considered as advancing environmental sustainability and climate resilience, but also as improving the health and wellbeing of the population. Affirmative action in terms of the availability of public parks with adequate area requirements and essential services at a neighborhood scale is required to redress the inequity of access; in addition, the accessibility of parks must be considered important during urban planning.

Management systems containing procedures, checklists, and descriptions for how various tasks should be conducted are often used in high-risk industries. Much has been written about the judicial and technological concerns of management systems, but less has been written on how to train staff in the use of them. Through a cognitive-constructionist perspective combined with social constructivism, this paper discusses how staff training can be designed to fit the characteristics of the workers. This paper focuses on how people learn in different ways, and how this is related to perspectives on knowledge. The method used is semi-structured interviews with twenty-seven workers in two different companies operating in the oil and gas-producing industry. The workers got only a short web-based theory course on the management system, with no practical exercises, repetitions, or other types of follow-ups. This is a signal that the management system is of less importance, and many of the workers thought they did not need it. Training must be designed to fit the workers, with practical exercises, repetition, and possibilities for on-the-job training. Accidents in this sector can cause human losses and great environmental harm, and this paper argues that better training of staff can prevent such accidents and reduce harm to the environment.

In an ongoing series of interviews, Challenges Advisory Board member and Nova Institute for Health Fellow Alan C. Logan meets with thought leaders, scientists, scholars, healthcare professionals, artisans, and visionaries concerned about health at the scale of persons, places, and the planet. Here, Dr. Diana H. Fishbein responds to a set of questions posed by Challenges. For over forty years, Dr. Fishbein, a neuroscientist and criminologist by training, has been at the forefront of research examining the intersections of biological, environmental, social, and physical factors as they relate to brain development, functioning, risky behavior, and life outcomes. Within this broad-ranging career, Dr. Fishbein was among the very first to conduct a dietary intervention study (eliminating refined carbohydrate foods) examining behavioral outcomes (i.e., nutritional psychiatry). This, combined with related research endeavors and experiences, led to a wider-lens view of prevention research, a desire to understand the physiological mechanisms that explain heterogeneity in positive and/or unfavorable outcomes in prevention programs, and a dynamic career devoted to the science of prevention. Here, Dr. Fishbein reflects on her career and its many twists and turns through a range of interdisciplinary work. Shediscusses prevention science through the lens of future possibilities and the need for scientists to lean toward advocacy and supporting evidence-based policy changes. Prevention science, as Dr. Fishbein explains, is at the heart of the many interconnected challenges of our time.

The Western approach to the natural world, considering “nature” as an object of scientific scrutiny and of exploitation for economic purposes, results in a separateness and subsequent alienation from nature. The overarching aim of this paper is to emphasize the limitations and consequences of this approach, including how nature is perceived, the value attributed to nature, and the substantial denial of cultural contributions from non-Western philosophical and scientific backgrounds. We also consider the Western attempt at balancing industrial and technological endeavors, aimed at preserving ecological equilibria. In this framework, we argue that the current ever-increasing concern about sustainability cannot be decoupled from the perception of nature and natural values, whether material, aesthetic, or spiritual. Therefore, modern sustainability challenges, mainly attributable to Western overexploitation of nature and natural resources, need to be considered in the context of the limited Western paradigms, which often leave the very definition of nature unanswered. We argue that efforts to ease the anthropogenic pressure on natural ecosystems, leading to their degradation, cannot be uniquely bounded by Western science and its technological appendices.

Forests are a vital source of food, fuel, and medicine and play a crucial role in climate change mitigation. Strategic and policy decisions on forest management and conservation require accurate and up-to-date information on available forest resources. Forest inventory data such as tree parameters, heights, and crown diameters must be collected and analysed to monitor forests effectively. Traditional manual techniques are slow and labour-intensive, requiring additional personnel, while existing non-contact methods are costly, computationally intensive, or less accurate. Kenya plans to increase its forest cover to 30% by 2032 and establish a national forest monitoring system. Building capacity in forest monitoring through innovative field data collection technologies is encouraged to match the pace of increase in forest cover. This study explored the applicability of low-cost, non-contact tree inventory based on stereoscopic photogrammetry in a recently reforested stand in Kieni Forest, Kenya. A custom-built stereo camera was used to capture images of 251 trees in the study area from which the tree heights and crown diameters were successfully extracted quickly and with high accuracy. The results imply that stereoscopic photogrammetry is an accurate and reliable method that can support the national forest monitoring system and REDD+ implementation.

This scoping review examines individual and societal use cases of Bitcoin in the peer-reviewed literature. Arksey and O’Malley’s scoping review methodology was used, and a comprehensive search strategy was employed using Web of Science and Engineering village databases. Articles were screened at the title and abstract and full-text levels by the authors. One author conducted data extraction to summarize the data. In total, 17 relevant articles were included in this review. Investment and savings were the most widely reported use cases at an individual level, with payments and international transfers less frequently reported in the studies. Only two studies reported on societal use cases of legal tender; however, only one country, El Salvador, executed its intention. Our study suggests that Bitcoin is being used by individuals around the world with little report of societal (e.g., country adoption) uses cases. For example, there is evidence on the internet and on a grass-roots level that Bitcoin is being used in circular economies; however, the peer-reviewed literature may not yet capture the extent and full benefits and challenges. As such, we provide ideas for future research to more comprehensively explore Bitcoin uses and its impacts on individuals and society.

Since ancient times, medicinal plants have been a universal source of biologically active substances with high potential for the treatment of various diseases and disorders. For centuries, traditional communities have often relied on medicinal plants to treat health problems. Therefore, accurate information is required and knowledge about traditional medicinal plants requires evaluation, and great attention should be given to the possible integration of these plants as therapeutic agents or as complements to conventional pharmacological therapies in the healthcare system. Recently, Griffonia simplicifolia (DC.) Baill., initially used as a holistic remedy, has attracted attention from many researchers and consumers because of its multiple health-promoting effects. This growing interest prompted us to give an updated review of the botanical, geographical, historical, and therapeutic potentials of Griffonia simplicifolia (DC.) Baill. in terms of its in vitro and in vivo health effects, nutritional uses, and possible applications in line with biodiversity and sustainability concepts. This paper also presents a quantitative research analysis of the published studies related to this plant that are available in the literature. To retrieve the publications related to this plant, a bibliographic search was carried out using the Scopus database. The bibliometric data were extracted and processed using VOSviewer software (v.1.6.16, 2020). Technological possible applications in terms of patents request presented was also performed. A total of 1386 publications, from the year 1970 to the year 2021, were obtained by the literature search, and these had been collectively cited 38,805 times. The large amount of literature data available documents the interest in this plant’s use as a tool for integrating traditional holistic healing approach, e.g., using plants, herbs, and holistic remedies, into the healthcare system as supporting tools and/or therapeutic agents, which is a current worldwide challenge.

In 2016, a localisation agenda was set across the international aid industry with the understanding that humanitarian interventions need to be led by local actors and local communities. Despite international agreements, the localisation efforts are largely failing. This paper demonstrates the challenges that prevent effective collaboration between international humanitarian agencies and crisis-affected communities. It draws on evaluation reports to highlight an inability to learn lessons or follow recommendations from previous crises. Based on the authors’ experiences, we present a novel framework for effectively collaborating with crisis-affected communities. The Communities Framework provides a pathway to establishing effective community collaboration and locally owned and led humanitarian interventions. The importance of local leadership, trust building, and local context are at the heart of the framework. In light of the need for a more localised and decolonial humanitarian response, this framework supports humanitarian actors and the affected communities in moving from a charity-led approach to one of mutual aid. The paper draws on alternative notions of compassion from the Global South of contemporary humanitarian interventions as a philosophical foundation for the framework. Caring for others and the world is central to implementing an appropriate and effective humanitarian response. There remains a largely unexplored scope regarding the outcome of resolving crises when both humanitarian actors and affected communities work as equal partners and how that will shape modern humanitarianism as we understand it today.

Forests are increasingly recognized for their beneficial roles in human health. However, there is a debate on how forest health benefits can be accessed equitably, particularly by vulnerable forest-dependent rural communities in low- and middle-income countries (LMICs). Access to forest health benefits is determined by a range of interconnected means, including property rights, as well as natural, physical, human, social, and financial capital. This paper presents a literature review of the roles of means of access in shaping human health effects of forests. Evidence suggests that variations in these means of access are associated with varying ability to access forest health benefits. However, existing evidence is thin, mixed, and weak. A conceptual model is then developed to provide a framework for understanding how means of access moderate the effects of forests on health in rural LMICs to guide the generation of strong evidence. The multiple interconnected factors moderating the health effects of forests at the core of the conceptual framework promote the multisectoral and transdisciplinary approaches needed to enhance equitable access to forest health benefits.

This article explores localisation in humanitarian settings as an example of sustainability and inner development. Through a case study from Syria, we discuss how localisation and remote management can lead to the mutual flourishing of individuals, communities and planetary health in the most challenging settings. Through localisation, we can rethink and reframe humanitarianism and integrate sustainability and personal development. Learning from these collaborations that highlight the importance of trust and interpersonal relations, the humanitarian and global health communities can reflect on how local individuals and communities can be further supported in their personal development and the sustainability of interventions that promote planetary health.

The impetus for this paper emerges from the growing interest in leveraging inner transformations to support a global shift in ways of seeing and being. We caution that without sufficient individual and systemic maturity, inner transformations will be unable to hold the whole story and that attempts to drive paradigmatic shifts in ill-prepared systems will lead to insidious harms. As such, interventions for inner change will not have sufficient protected niche space to move beyond the boundaries of best practices towards wise practices. Drawing on Indigenous trans-systemics, we offer the metaphor of pearls as an invitation to recontextualize how inner transformations are conceived and approached in the metacrisis. To further develop this notion, we share a story of Wendigo and Moloch as a precautionary tale for the blind pursuit of inner and outer development. Weaving together metaphor, story, and scientific inquiry, we bring together Anishinaabe and Western knowledge systems for the purposes of healing and transformation. We hope that this paper will create space for wise practices—gifts from Creator to help sustain both Self and the World—to emerge, establish, and flourish. We invite readers on an exploration into the whole system of systems that are endemic to Anishinaabe cosmology, and a journey of reimagining new stories for collective flourishing amidst the metacrisis.

Bitcoin is a complex phenomenon, whether in terms of the macro factors affecting its price or its role in the global energy infrastructure. However, extant literature pays too little attention to exploring the internal mechanisms of the protocol to be able to link them to how they affect the visible characteristics of Bitcoin. This paper uses secondary data from highly reputable Bitcoin-focused sources to systematically map the processes that enable Bitcoin to function as a peer-to-peer cash system. Novelty is achieved by applying the established and versatile “4I” organisational learning framework to provide a new lens through which to understand how the processes within Bitcoin enable and facilitate different types of changes to the protocol. Further insights are provided to organisational learning from Bitcoin, in relation to managing mission-critical changes to organisational systems. In addition, it presents an option for dealing with irreconcilable internal differences to “hard-fork” part of the organisation. While the scope of this paper is limited to secondary data, opportunities for further research, including primary data collection, are outlined to explore how Bitcoin knowledge disseminates within communities or companies.

The physical conquest of European powers on the rest of the world for the imposition of an accumulation of wealth monopoly and the destruction of native societies remains the foundation of the current global economy. Despite concepts of human flourishing, a term connected to empowerment that acts as an architectural structure within the development and sustainability discourse, the destruction of our planet and collective human wellbeing is not at the forefront of international political agendas. Scholars argue that the development agenda is maldevelopment due to the unrequested interventions delivered to communities, mainly in the Global South. Thus, despite the Sustainable Development Goals (SDGs), the implementation of inner dimensions that facilitate empowerment and are an integral part of development is missing from these sophisticated global frameworks. This research article repositions empowerment and compassion at the centre of the sustainable development discourse by drawing on the Inner Development Framework, particularly goal one—Being—‘Relationship to Self’ and goal three—Relating—‘Caring for others and the World’ and the Capabilities Theory as a guiding theoretical underpinning. On this basis, this article presents a qualitative interpretative study that examines the lived experience of women and their journeys to empowerment. The key findings indicate an intricate relationship between wellbeing and empowerment and the realisation of inner development as a tool to re-imagine alternative futures. In addition, industries are profiteering from a sustainability and development agenda that is failing to address the disablement of communities by a paternalistic approach to empowerment.

Much of the attention on bitcoin relates to its ability to store value over time or whether you will one day by able to buy a cup of coffee with it. Much less attention is given to bitcoin’s potential role as a unit of account. This opinion piece proposes that bitcoin has potential to provide a consistent unit of account for organisations to adopt, but also to assist them in making and measuring meaningful business developments. The paper draws from the business improvement philosophy of Theory of Constraints to propose that unit of account, particularly within high inflation environments, is critical to consider. An illustrative case of a well-known publicly traded company, Microstrategy, provides an example and logic for a company choosing to integrate bitcoin into a business. The paper also gives attention to how the adoption of bitcoin can promote the development of renewable energy infrastructure and provide staff with opportunities for personal development to support their well-being.

This is a report on an inaugural medical student elective, Microbiomes Matter: The Path to Regenerative Systems of Farm, Food, and Health, from the perspective of the student participants. Recognizing food as medicine is gaining support across many settings. However, little is known about how medical schools engage in this holistic approach. Integrating food systems and the connections to soil and human health through microbiomes into medical education represents a transformative shift towards more holistic healthcare practices. We describe the course content and impact of a medical school elective in food systems. This elective employed a systems lens and planetary health perspective to explore the impact of climatic factors and environmental degradation on farms, nutrition, and non-communicable lifestyle diseases. Through the two-week course, medical students gained insights into sustainable food systems, supply chains, and the importance of regenerative agriculture. The course also provided a comprehensive overview of the gut microbiome, nutrition, technologies, and the economics of food systems, including their impact on lifestyle diseases. By fostering a systems-oriented mindset, this elective better equips medical students to address the complex challenges of human and planetary health and promote regenerative, sustainable, culturally sensitive, and robust systems of farm, food, and health.

Mars is a focus of New Space Age exploration and colonisation, but there are significant challenges to successful colonisation by humankind. Environmental microbes play a key role in supporting the ecosystems of Earth, especially within the biodegradation and bioremediation sectors. However, the repurposed roles of microbes on Mars and their associated uses to colonists remain incompletely defined. The aim of this review was to examine the key roles of microbes on Earth and how they have been employed by humans to tackle four pivotal environmental challenges associated with the colonisation of Mars, namely the physical environment, the creation of a hospitable environment via terraforming, environmental sustainability and life support, and finally, renewable processing technologies. Some species of microbes were found to be tolerant of the ever-changing physical environment on Mars (freeze–thaw and UVC exposure) making them useful for bioremediation applications. Employing perchlorate-remediating microbes for their ability to bioremediate the soils of sodium perchlorate, which is present in Martian soils, in addition to their innate ability to cycle nutrients through the biosphere showed promise in establishing sustained crops to support colonists. The employment of terrestrial environmental microbes is a necessary part of overcoming key environmental challenges to successfully colonise Mars. Without this, future New Space exploration is unlikely to be successful.

Sodium perchlorate is a toxic salt-based compound found both terrestrially, (due to pollution) and extraterrestrially on the surface of Mars. Perchlorate pollution poses a risk to agricultural-based activities as once it enters soils/waterways it can be passed through the food chain via bioaccumulation. The purpose of the current study was to observe the perchlorate reduction potential of putative candidate bioremediation strains; Escherichia coli 25922 and E. coli 9079, Paraburkholderia fungorum, Deinococcus radiodurans and Dechloromonas aromatica both independently and in co-cultures, when exposed to 3000 mg/L (0.3%) sodium perchlorate. This was carried out in both a minimal medium environment and within an environment void of nutrients, using Raman spectroscopy to assess their potential for the bioremediation of Martian soils. The perchlorate reducing potential of all strains was 16% higher in reverse osmosis deionised water than in minimal medium, the former having a total absence of Nitrate. It was found that E. coli 25922 is a perchlorate reducer, which has not been previously described. Additionally, co-culturing of bacterial strains was found to have a higher bioremediation potential than individual strains. These findings suggest that not only could perchlorate pollution be remediated, but that the perchlorate composition of the Martian surface may support bioremediation microbial life, aiding in future colonisation.
