This article examines how redefining health through the perspectives of One Health, EcoHealth and Planetary Health can enrich Physical Education (PE) by advancing both health and environmental sustainability. While PE and health education are often treated as separate subjects, most PE curricula worldwide emphasise the promotion of an active lifestyle as a key component of health education through PE. This promotion of an active lifestyle is central to the concept of physical literacy (PL), which is a fundamental aspect of quality PE according to UNESCO (2015). This article focuses on how PE, contributing to health education through the promotion of PL, can evolve to incorporate sustainability goals through the recent new definitions of approaches to health. One Health approach underscores the interconnections between human, animal and environmental health, expanding PL to address zoonotic diseases and ecological impacts. EcoHealth highlights the sustainability of ecosystems, promoting PE activities that (re)connect humans with the more-than-human worlds without causing environmental harm. Planetary Health takes a global perspective, encouraging sustainable physical activities that reduce ecological footprints, such as cycling and walking. By integrating these holistic frameworks, PE can nurture not only individual health outcomes but also environmental stewardship and global health awareness. This shift seeks to educate individuals about their PL, but also their responsibility in preserving ecosystems and the planet, fostering a more sustainable and environmentally aware generation through PE.

Within environmental education research, there is an ongoing interest in trying to understand what factors might lead to pro-environmental action and pro-environmental behaviours. This study explores the relationship between environmental attitudes and self-perceived action competence for sustainability by combining a questionnaire measuring self-perceived action competence for sustainability (SPACS-Q) with a questionnaire measuring environmental attitudes, the 2 factor Model of Environmental Values (2-MEV-Q), among 236 primary school student teachers in France. Our results show that the SPACS-Q adapted to the French context is largely valid within this sample and that the factor Preservation in the 2-MEV model is a predictor for SPACS. This connection is strongest for the factor Willingness to act. Likewise, we conclude that age impacts the SPACS factor Confidence in one’s own influence, whereas other variables such as training in sustainable development issues do not impact any of the SPACS factors. The study provides some insights into how self-perceived action competence and pro-environmental attitudes might be promoted through education.

This article explores the evolving rhetoric of commercial whaling advocates in Japan and Norway, who frame whaling as essential for global, national, and personal health. I show that proponents leverage sustainability discourse and health narratives to present whaling as beneficial for marine ecosystems, national food security, and individual well-being. By coopting the language of the United Nations’ Sustainable Development Goals (SDGs) and casting whaling as “healthy,” the whaling industry and its backers challenge the anti-whaling hegemony, portraying it as irrational and unscientific. While the alleged environmental benefits of whaling have been significant to the rhetorical arsenal of the industry since at least the 1990s, a growing emphasis on the personal health benefits of whalemeat suggests the opening of a new front in struggles to influence public opinion.

In Spring 2024, with funding from the Japan Foundation, we traveled to Japan to interview organic farmers. We talked to Yae Fujimoto, a second-generation organic farmer who carries on her father's mission to return Japan to its rural roots in Kamogawa; Raymond Epp, a farmer and teacher outside Sapporo and the first to translate “regenerative farming” into Japanese; and Takumi Watanabe, who ditched the corporate grind at age 24 to grow persimmons in Ibaraki. Our interviews help us reflect on the future of food in Japan through its nascent but growing organic movement.

Most common pool resource (CPR) dilemmas share two features: they evolve over time and they are managed under environmental uncertainties. We propose a stylized dynamic model that integrates these two dimensions. A distinguishing feature of our model is that the duration of the game is determined endogenously by the users’ collective decisions. In the proposed model, if the resource stock level below which the irreversible event occurs is known in advance, then the optimal resource use coincides with a unique symmetric equilibrium that guarantees survival of the resource. As the uncertainty about the threshold level increases, resource use increases if users adopt decision strategies that quickly deplete the resource stock, but decreases if they adopt path strategies guaranteeing that the unknown threshold level is never exceeded. We show that under relatively high uncertainty about resource size, CPR users frequently implement decision strategies that terminate the game immediately. When this uncertainty is reduced, they maintain a positive resource level for longer durations.

This paper examines exhibits at the Shanghai Expo and the urban improvement schemes undertaken for the Shanghai Expo for what they reveal about the ideals for and experiences of urban modernity in contemporary China. Rather than focus on the experiences and perceptions of a global audience, this paper examines how the Expo sought to speak to a domestic audience about state legitimacy through its messaging about urban citizenship and urban modernity. It argues that the manner in which the Expo promoted certain forms of sustainability and the domestic audience's experiences with Shanghai urban improvements revealed tensions in the nation's development model and excluded sectors of the population from participation.

This paper examines an endogenous growth model that allows us to consider the dynamics and sustainability of debt, pollution, and growth. Debt evolves according to the financing adaptation and mitigation efforts and to the damages caused by pollution. Three types of features are important for our analysis: the technology through the negative effect of pollution on TFP; the fiscal policy; the initial level of pollution and debt with respect to capital. Indeed, if the initial level of pollution is too high, the economy is relegated to an endogenous tipping zone where pollution perpetually increases relatively to capital. If the effect of pollution on TFP is too strong, the economy cannot converge to a stable and sustainable long-run balanced growth path. If the income tax rates are high enough, we can converge to a stable balanced growth path with low pollution and high debt relative to capital. This sustainable equilibrium can even be characterized by higher growth and welfare. This last result underlines the role that tax policy can play in reconciling debt and environmental sustainability.

The diet proposed by the EAT-Lancet Commission has faced criticism concerning its affordability. This study aimed to investigate the cost associated with a greater alignment to the EAT-Lancet reference diet in the province of Québec, Canada. The dietary habits of 1147 French-speaking adults were assessed using repeated web-based 24-h recall data collected between 2015 and 2017 in the cross-sectional PRÉDicteurs Individuels, Sociaux et Environnementaux (PREDISE) study. Diet costs were calculated using a Nielsen food price database. Usual dietary intakes and diet costs were estimated using the National Cancer Institute’s multivariate Markov Chain Monte Carlo method. Adherence to the EAT-Lancet diet was assessed using the EAT-Lancet dietary index (EAT-I). Associations between diet costs and EAT-I scores were evaluated using linear regression models with restricted cubic splines. After adjustment for energy intake, a higher EAT-I score (75th v. 25th percentiles) was associated with a 1·0 $CAD increase in daily diet costs (95 % CI, 0·7, 1·3). This increase in diet costs was mostly driven by the following component scores of the EAT-I (75th v. 25th percentiles, higher scores reflecting greater adherence): vegetables (1·6 $CAD/d, 95 % CI: 1·2, 2·1), free sugars (1·6 $CAD/d, 95 % CI: 1·3, 1·9), fish and plant-based proteins (1·4 $CAD/d, 95 % CI: 1·0, 1·8), fruits (0·9 $CAD/d, 95 % CI: 0·4, 1·3) and whole grains (0·4 $CAD/d, 95 % CI: 0·0, 0·8). Inversely, a greater score for the poultry and eggs component was associated with reduced diet costs (–1·2 $CAD/d, 95 % CI: −1·7, −0·7). This study suggests that adhering to the EAT-Lancet diet may be associated with an increase in diet costs in the province of Québec.

Education is essential for addressing the global environmental crisis and engaging students through experiential learning is crucial. In physical education, physical literacy offers a holistic approach to sustainable education, with plogging exemplifying this integration. This study investigates the perceptions of Physical Education Teacher Education (PETE) students regarding the implementation of plogging in school curricula. Using qualitative interviews with 80 PETE students and analysing responses with NVIVO 12 software, the study reveals mixed feelings about this innovative practice. Participants see plogging as valuable for fostering both physical literacy and environmental awareness. However, concerns about feasibility include the need for institutional support, curriculum flexibility and community involvement. These findings highlight the potential of plogging to enhance educational programmes by combining physical activity with environmental stewardship. The results can inform the development of future educational strategies that integrate plogging to promote sustainability and holistic student development.

While malnutrition (including both undernutrition and overweight/obesity and related non-communicable diseases) remains a persistent challenge in countries around the world, it is far from alone as a threat to human development and wellbeing – and is increasingly viewed as intersecting with climate change and environmental degradation. At the crossroads of these issues, animal-source foods (ASFs, including meat, fish, seafood, dairy and eggs) have attracted considerable attention in recent years, both for their role in diets and for their environmental impacts. Heated debate has focused on the potential benefits of reducing consumption of ASFs as well as the potential nutritional risks associated with this. ASF production also plays an important role in livelihoods, particularly in low- and middle-income countries. ASFs are also central to many food cultures and traditions, highly valued by many consumers. As the issues associated with ASFs are intertwined, they must be considered jointly and with nuance. Given wide global ranges in ASF consumption, environmental footprints and malnutrition rates and types, considering equity (in terms of ASF consumption and production) is also critical. This review examines these complex issues, discussing ASFs from the perspectives of nutrition and health, environmental impacts, livelihoods and society, and equity. It also examines potential future options for reducing environmental impacts of ASFs.

It is not often that international collaborations are sustained for any significant period, let alone for three decades. However, despite relying on largely voluntary contributions of individuals within its member institutions, the International Network of Agencies for Health Technology Assessment (INAHTA) has not only been an example of sustained collaboration over 30 years but also an example of how an initially modest collaboration can grow and thrive. Current and former serving Chairs and secretariat of the Network have come together to review network documents and outputs and reflect on the history of INAHTA, since its inception in Paris in 1993. Building on the paper from Hailey et al 2009 that documented the growth of the network after 15 years, we have considered and documented the factors that we believe have helped sustain the network and enable it to flourish in the subsequent 15 years. We have also considered the various challenges experienced along the way, as these too can aid in making a collaboration stronger. Future directions for the network have also been contemplated, given the evolving nature of HTA and the regional collaborations that have recently emerged. We hope that by sharing the lessons learned from this living example of international global collaboration relationships between like-minded organizations can be similarly fostered and enhanced into sustainable collaborations, for the benefit of all.

In political decision-making processes in Greenland, comparisons are often drawn with Denmark, Scandinavia, the Faroe Islands, and Iceland. With Greenland as a case, this article analyses a series of aspects across the societies to highlight the politics of comparisons, which are taken for granted, and to emphasise contextual conditions. Comparisons are central to cultural meaning-making and navigation with nation building strategies. We conclude that the current comparisons are significant in terms of explaining Greenland’s challenges with a vulnerable economy and with the sustainable use of natural and human resources. To utilise local resources and create a sustainable livelihood, there is a need to break from the existing trajectories based on the current politics of comparison to explore local conditions more carefully and find other models of inspiration. By developing the concept of island operation, the article unfolds distinct characteristics of the Greenlandic socio-economic structures and includes statistical data on trade, education, and the labour market to support the identification of conditions that can contribute to future analyses of Greenland’s sustainable development. This analysis has relevance for societies that share geographical and cultural conditions with Greenland and post-colonial countries that must deal with complex path dependencies to navigate towards sustainable development.

The 5th International Polar Year (IPY-5) in 2032–2033 represents an important next step in the legacy of the oldest continuous climate research program created by humanity, which intentionally began during a Solar Maximum with IPY-1 in 1882–1883, following the Little Ice Age. Current IPY-5 planning by the International Arctic Science Committee (IASC) and Scientific Committee on Antarctic Research (SCAR) is “From IPY-4 to IPY-5” with scope since 2007–2008, considering relevant large-scale polar process, international activities and UN decades. Additionally, there are essential features to incorporate into IPY-5 planning with Indigenous knowledge as well as next-generation leadership along with international science connections across the United Nations, involving core integration of data system and Earth–Sun system research, which accelerated with the International Geophysical Year (IGY) in 1957–1958 that was renamed from IPY-3. As memorialized in the 1959 Antarctic Treaty: “the International Geophysical Year accords with the interests of science and the progress of all mankind.” Importantly, at the height of the Cold War with “forever” legacy, the 1959 Antarctic Treaty became the first nuclear arms agreement, applying science diplomacy among allies and adversaries alike based on “matters of common interest.” Recognizing current challenges to enable inclusive dialogues – especially in the Arctic – planning for IPY-5 is far enough into the future to be imaginative and hopeful but close enough to be practical, especially to produce synergistic outcomes that inspire and empower next-generation leaders across the International Decade of Sciences for Sustainable Development from 2024 to 2033. Planning “From IPY-3 to IPY-5” – this invited Cambridge Prisms Perspective extends and amplifies the IASC-SCAR concept with its visionary principles – “striving for holistic, systemic, transdisciplinary research approaches” – for the benefit of all on Earth across generations.
