Will a warmer world be a sicker world? What is it about the New England landscape that supports the proliferation of Lyme disease? How are local wildlife trade and global species invasions contributors to emerging diseases such as the 2003 outbreak of monkey pox virus in the midwestern United States? Undergraduate students explore these and related questions in BIOL 1455 Planetary Health: global environmental change and emerging infectious disease—a new online asynchronous course at Brown University. Planetary health is gaining traction in the curricula of institutions of higher learning and online asynchronous courses offer the promise of scaling up to make grand challenges education accessible to many. In our new course, we assessed student learning outcomes (LOs) and sentiment towards the health of humans and the planet using a mixed-methods approach. Students demonstrated competency in each of the LOs after course completion as measured in a pre–post assessment scored with a standardized rubric. Student sentiment was analyzed with an immersion–crystallization qualitative analysis to elucidate themes in responses to the assessments. Many themes on the pre-assessment focused on barriers and problems associated with the health of humans and the planet, while themes on the post-assessment centered on more solutions-based thinking. Collectively, these findings indicate that this online asynchronous course successfully educated students about the myriad challenges facing human and planetary health, broadened knowledge of environmental changes (beyond climate change) that impact health, formalized understanding of now common terms such as “emerging infectious diseases”, and bolstered hope by offering solutions and peer community (even when virtual). Future efforts to integrate planetary health into higher education should focus on broadly accessible and scalable courses, full programs of study (i.e., majors/scholarly concentrations), and extension into institutional programs focused on ensuring equity and wellness for all.

While blockchain and distributed ledger technology offer immense potential for applications in transparency, security, efficiency, censorship resistance, and more, they have been criticized due to the energy-intensive nature of the proof of work consensus algorithm, particularly in the context of Bitcoin mining. We systematically explore the state-of-the-art regarding the relationship between Bitcoin mining and grid decarbonization. We specifically focus on the role of flexible load response through proof of work mining as a potential contributor to renewable energy penetration and net decarbonization of the energy grid. The existing literature has not comprehensively examined this area, leading to conflicting views. We address the gap, analyzing the capabilities and limitations of Bitcoin mining in providing flexible load response services. Our findings show that renewable-based mining could potentially drive a net-decarbonizing effect on energy grids, although key adaptations in mining practices are needed to fully realize this potential. Overall, the paper suggests a re-evaluation of the environmental impact of Bitcoin mining, highlighting its potential role as a facilitator for renewable energy expansion, and decarbonization more broadly.

As climate change continues unabated, research is increasingly focused on capturing and quantifying the lesser-known psychological responses and mental health implications of this humanitarian and environmental crisis. There has been a particular interest in the experiences of young people, who are more vulnerable for a range of reasons, including their developmental stage, the high rates of mental health conditions among this population, and their relative lack of agency to address climate threats. The different geographic and sociocultural settings in which people are coming of age afford certain opportunities and present distinct challenges and exposures to climate hazards. Understanding the diversity of lived experiences is vitally important for informing evidence-based, locally led psychosocial support and social and climate policies. In this Project Report we describe the design and implementation of the “Changing Worlds” study, focusing on our experiences and personal reflections as a transdisciplinary collaboration representing the UK, India, Trinidad and Tobago, Guyana, Barbados, the Philippines, and the USA. The project was conceived within the planetary health paradigm, aimed at characterizing and quantifying the impacts of human-mediated environmental systems changes on youth mental health and wellbeing. With input from local youth representatives, we designed and delivered a series of locally adapted surveys asking young people about their mental health and wellbeing, as well as their thoughts, emotions, and perceived agency in relation to the climate crisis and the global COVID-19 pandemic. This project report outlines the principles that guided the study design and describes the conceptual and practical hurdles we navigated as a distributed and interdisciplinary research collaboration working in different institutional, social, and research governance settings. Finally, we highlight lessons learned, specify our recommendations for other collaborative research projects in this space, and touch upon the next steps for our work. This project explicitly balances context sensitivity and the need for quantitative, globally comparable data on how youth are responding to and coping with environmental change, inspiring a new vision for a global community of practice on mental health in climate change.

A new network of over 72 organizations from 12 countries was activated during a convening at ARTIS in Amsterdam on 26–27 September 2022. Representatives are aligned with the transdisciplinary field and social movement of Planetary Health, which analyzes and addresses the impacts of human disruptions to natural systems on human health and all life on Earth. The new European Planetary Health Hub consists of organizations from various sectors, including universities, healthcare, youth, business, and civil society. The Convening, co-organized by the Planetary Health Alliance (PHA), the European Environment and Sustainable Development Advisory Councils Network (EEAC), and Natura Artis Magistra (ARTIS), aimed to develop Planetary Health Working Groups for Education, Policy Engagement, Research, and Movement Building. The Convening resulted in an outline for each of the Working Group’s aims, visions, missions, priorities, and activities, and set the framework for sustaining their activities in the future through the establishment of the European Planetary Health Hub Secretariat in the Netherlands. The Hub members shared lessons learned, built relationships, and developed artwork-inspired perspectives on Planetary Health. In conclusion, the Convening led to the establishment of a strong European foundation to contribute to the transformations needed for sustainable, just, and equitable societies that flourish within the limits of our ecosystems.

As the number of refugees in the world is increasing and it is known that social inequality negatively impacts mental health, it is important to study integration policies, such as labour market measures. In this article, the strategic interventions of the Swedish Public Employment Service are analysed to determine how the agency’s management handled and implemented the legal changes in the new support document for its case workers. The focus is on the effects of the changes in the legal text that transferred the responsibility for establishment initiatives for newly arrived migrants to the agency and, as a result, changed the conditions for newly arrived refugees’ mental health in the new establishment programme. Eight people representing different management functions at the agency were interviewed. The results show that the intention in the new programme to view newly arrived refugees in the same way as all other unemployed people, rather than as a special category, has meant that less attention is paid to the refugees’ mental health, and the opportunities for the agency’s street-level bureaucrats to help clients have decreased. In the face of predicted growing numbers of people having to abandon their homes due to conflicts and climate changes, governmental strategies such as these needs to be revisited in order for societies worldwide to be better prepared for that challenge.

Deinstitutionalization of psychiatric care has been associated with increased homelessness, crime, and suicide, partly owing to insufficient, adequate, and accessible community resources. Therefore, appropriate resource placement is a key deinstitutionalization issue. The study’s aim was to identify residential group homes for people with mental illness in Kochi Prefecture, Japan, and the social resources necessary for social reintegration using a geographic information system (GIS). Everyday living areas (ELAs), as defined by the Japanese Community-Based Integrated Care System for People with Mental Illness (CICSM), were assessed using ELA location simulations. We used GIS to determine the spatial distribution of group homes, visiting nursing stations, psychiatric hospitals, daycare centers, and employment support offices. Following the CICSM definition of ELAs, we identified areas that people with mental illness could reach within 30 min on foot/by bicycle and counted the number of social resources in them. The ELA location simulation results suggest that policymakers should avoid uniform distribution of ELAs according to the CICSM definition. Establishing ELAs in suburban areas requires careful consideration of the available community resources, number of people with mental illness, existing support systems, and feasibility of the location.

Fish is a good source of Animal Source Proteins (ASP). Families from low-income countries with limited access to other animal source proteins can utilize it to improve the nutrition status of infants and young children. The objective of the study was to assess if fish fed during the early complementary feeding period had an effect on improved head circumference (HC) and mid-upper arm circumference (MUAC) among infants aged 6–7 months. A randomised controlled trial was conducted from April 2019 to January 2020 in the Samfya district, Luapula Province, Zambia. The infants (238) were randomised to either the fish group (intervention) or the sorghum group (control). Every week for a period of 6 months, infants received seven sachets of fish powder and sorghum powder, respectively. Compliance was also monitored during the fish powder distribution. The head circumference measurements were conducted at baseline and once each follow-up month for a period of six months while the MUAC measurements were conducted twice (at baseline and endline). Using statistical software for data science (STATA) (version 16), a linear mixed effect model was used to analyse the data. The results showed that fish improved head circumference for age z score (HCZ) by 0.53 (95% CI: 0.23–0.82), p-value < 0.001, and MUAC by 0.36 (95% CI: 0.13–0.59) p-value < 0.002. Therefore, fish can be used as the main source of protein in complementary foods for infants and young children in low-income communities with limited access to meat. Full article

Soil pollution is a threat to food security and ecological and human health. Cd is one of the most common pollutants in agricultural soil and, due its human toxicity, one of the most hazardous. Amaranth is a documented hyperaccumulator of Cd and other pollutants, and it is commonly grown in Asia and South America. A considerable amount of amaranth is grown in suboptimal conditions, including nutrient-poor acidic soils. The objective of this experimental study was to examine the capacity of Amaranthus hypochondriacus to extract Cd from a nutrient-poor, acidic substrate that was spiked with different concentrations of Cd (2 and 20 mg kg−1 dw) during a period of 180 days. The plants grown in the substrate that was spiked with 20 mg Cd kg−1 dw did not develop into mature plants, but the plants grown in substrate that was spiked with 2 mg Cd kg−1 dw extracted a significant amount of Cd from the substrate by accumulating it into the above-ground biomass. The Cd levels varied from 113 to 176 mg kg−1 in the stems at the four measuring points, and from 64 to 94 mg kg−1 in the leaves. The concentrations in the plants increased with time and reached a maximal concentration of 176 ± 45 mg kg−1 dw for stems and 94 ± 41 mg kg−1 dw for leaves after 180 days. The mean bioaccumulation factor in the plants was 86 ± 15 after 90 days, 72 ± 12 after 120 days, 105 ± 37 after 150 days, and 99 ± 31 after 180 days, which confirms the previously reported capacity of Amaranthus hypochondriacus to hyperaccumulate Cd. Amaranthus hypochondriacus may, thus, be used to improve ecological and human health by remediating moderately Cd-polluted soils, even in nutrient-poor acidic soils. Full article

Bitcoin has been embraced by many individuals with strong right-leaning views on freedom, property rights, and self-sovereignty. Among left-leaning progressives, Bitcoin is often quickly dismissed as irrelevant or a major source of carbon emissions. Bitcoin seems, however, to be full of surprises. A rapidly advancing body of anecdotal evidence suggests that its adoption may affect causes important to progressives, mitigating greenhouse gas emissions, accelerating electrification of economies, alleviating poverty, and supporting human rights for people living under political repression, even though scientific confirmation is lagging. In this paper, I highlight how a Pragmatist perspective can be applied to Bitcoin, a technological and financial innovation that may well reshape how humans perceive and use money, preserve wealth, and structure governance. I first cover Bitcoin’s technological and financial fundamentals and some core concepts of Pragmatism, before outlining how Bitcoin might surprise progressives. Pragmatism offers a philosophical and political grounding for left-leaning “progressive Bitcoiners” who prioritize environmental and social well-being and view inclusive deliberative democracy as the preferred form of governance.

While there is growing optimism for inner transformations to catalyse systemic shifts towards more sustainable ways of being, no study so far has attempted to assess how well current interventions for inner development address core requirements for collective wellbeing. In this article, we apply a novel assessment framework to examine how mindfulness-based interventions address inner and outer sustainability criteria during a global health emergency. This inquiry informs a growing field of study concerned with leveraging inner transformations for systemic shifts towards sustainability progress. Using three prominent online mindfulness-based offerings as a case study, we demonstrate that mindfulness-based interventions have a broad range of potential desirable to detrimental implications for social and biophysical systems. We conclude by discussing how normative conceptions of inner interventions might be contextualised anew to effectively support more viable, just, and inclusive transformations towards long-term viability.

Change Starts Within is the welcome title to the Inner Development Goals (IDGs) toolkit. The tools are resources to support the inner growth of individuals and organizations committed to the Sustainable Development Goals (SDGs). This reflection article emerged from reviewing my earlier experiences in inner development while collaborating in the development of the IDGs. Years of continuing inner growth involved going through the liminal stage several times. Evolution is ongoing. Liminality has been conceptualized through different ways of embodying knowing by anthropologists, phenomenologists, psychologists, philosophers, scientists, and spiritual teachers, among others working in transformational processes. Through a lived experience approach, I explore my relationship with the liminal stage. Learning and practicing the “unseen” inner muscle leads to becoming “sensitive” to the subtle qualities. It involves perceiving the world through sensorial qualities, which leads to a conscious action to purposefully commit to what lies along the path to sustainable humanity. At the same time, I notice the limitations for understanding the language of the inner world. The inner world communicates through dynamic manifestations of the lived experience, and when conceptualized in a logical and structured way, it constrains how the animacy of the inner being can be described. The invitation to understand spaces of inner transformation in liminality is to learn to manifest the state of being. The effects of understanding inner development accelerate wisdom and human evolution. Full article

Addiction is a complex psychosocial problem that has significant psychosocial effects on family members. The aim of this study is to gain insight into the burden and psychological distress suffered by caregivers of drug abusers. Ninety-nine caregivers of hard drug addicts participated in this study. The test group consisted of 50 participants and the control group had 49 participants. The participants filled out the General Demographic Questionnaire; Caregiving and the Experience of Subjective and Objective Burden; SCL-90-R; and WHOQOL-BREF. Caregivers of addicts who were preparing to join the community exhibited a significantly higher objective burden, subjective burden, subjective stress burden and greater psychological distress in comparison to caregivers of addicts in the community, and their quality of life was poorer (p < 0.001). The following showed to be risk factors for psychological distress: families with a greater number of children, marital, employment and economic status and duration of addiction. The protective factors were better quality of life, long-term marriage and higher education level of caregivers. Caring for addicts who are living with their families is a significant responsibility and burden for caregivers. Full article

Environmental degradation in Paraguayan ecosystems relates to anthropogenic intervention and has intensified with wildfires and drought. To help mitigate forest cover loss, the local government created laws, parceled land to private owners, and established protected areas. How differences in land tenure regimes affect dendrology and biodiversity remain to be answered. This preliminary study examined the differences and similarities between three protected area forests (National Park Ybycuí, and Natural Monuments Cerro Koi, Cerro Chorori) and three family-owned forests in Guairá, Central, and Paraguarí of eastern Paraguay. Forty-three transects were established following FAO protocols to examine tree diversity, floristic composition, and complementary vegetation structure information using two biodiversity indexes. Nine hundred and three individuals were registered, representing 92 species, 80 genera, and 35 families. The most abundant families were Fabaceae, Rutaceae, Myrtaceae, and Rhamnaceae; and the most abundant genera were Pilocarpus, Columbrina, Acrocomia, Plina, and Astronium. The most important species were Parapiptadenia rigida, Peltophorum dubium, and Astronium fraxinifolium. Results showed higher species richness and significantly greater tree diversity, but a nonsignificantly larger diameter in private forests compared to protected areas studied. Detected differences were small, indicating a need for additional research of forests with differing land tenure regimes as climate dynamics continually shift and management strategies show effects.

The emergence and reemergence of infectious diseases caused by viruses continue to be a major public health concern globally, affecting both humans and animals. One such disease is monkeypox, a zoonotic infection caused by the monkeypox virus (MPXV) that has recurred in sub-Saharan Africa over several decades. Notably, the 2022 outbreak of monkeypox in Nigeria follows a deadly outbreak in 2017, which was preceded by the disease’s first recorded outbreak in 1978. Epidemiological investigations in 2017 showed no apparent link between human monkeypox cases and the outbreak that year, indicating the potential existence of multiple sources of the virus and limited human-to-human transmission. This underscores the presence of an alternative ecological niche in humans. Furthermore, in some communities in Nigeria, monkeys are regarded as sacred and not hunted or consumed, leading to their proliferation and increased likelihood of MPXV transmission. This mini-review focuses on the occurrence, epidemiological distribution, geographical distribution, endemicity, and possible solutions to reduce the spread of human monkeypox in Nigeria. The implications of this reemergence and the need for effective public health measures to prevent and control outbreaks of monkeypox are also discussed. Full article
