Background

Environmental determinants such as air pollution and extreme heat contribute to approximately 13 million preventable deaths globally every year. Paradoxically, the health-care sector itself considerably affects planetary health, with operating rooms accounting for 10–20% of hospital-related greenhouse gas emissions. In response, the Sustainable Health Systems Community of Practice developed a sustainability scorecard, later adapted into the national Sustainable Perioperative Care Scorecard by the CASCADES initiative. This tool outlines 13 evidence-based targets to guide sustainable practices in perioperative care. This quality improvement pilot project aimed to show the utility of this national, freely available scorecard in a resident-led assessment of perioperative sustainability practices.

Methods

Residents partnered with staff surgeons to apply the 2023 CASCADES Sustainable Perioperative Care Scorecard across two major academic institutions. Assessments covered domains such as sustainability leadership, anaesthetic gas usage, reduction of low-value care, reusable instrument adoption, and waste segregation.

Findings

Both institutions showed strong engagement with resident-led evaluations. Scorecard results could distinguish differences and opportunities in practice between the two sites. Both hospitals scored well on elements relating to limiting low-value care, minimising intraoperative fresh gas flows, and implementing reusable anaesthesia equipment, and several opportunities for improvement were identified.

Interpretation

This pilot project illustrates the practicality of a national scorecard for evaluating perioperative sustainability and underscores the important role of residents in leading climate-conscious health-care improvements. Engaging trainees in structured assessments can accelerate institutional efforts towards more sustainable perioperative practices.

背景：空气污染和极端高温等环境决定因素每年在全球造成约1300万例可预防的死亡。矛盾的是，卫生保健部门本身对地球健康影响很大，手术室占医院相关温室气体排放量的10-20%。作为回应，可持续卫生系统实践社区开发了可持续性记分卡，后来被CASCADES倡议纳入国家可持续围手术期护理记分卡。该工具概述了13个循证目标，以指导围手术期护理的可持续实践。这个质量改进试点项目旨在展示这个全国性的、免费的记分卡在住院医生主导的围手术期可持续性实践评估中的效用。方法住院医师与主治医生合作，在两家主要学术机构应用2023 CASCADES可持续围手术期护理记分卡。评估涵盖了可持续性领导、麻醉气体使用、减少低价值护理、可重复使用仪器的采用和废物分类等领域。两所机构都表现出对住院医生主导的评估的强烈参与。记分卡结果可以区分两个站点在实践中的差异和机会。两家医院在限制低价值护理、尽量减少术中新鲜气体流动和使用可重复使用的麻醉设备等方面得分很高，并确定了一些改进的机会。该试点项目说明了评估围手术期可持续性的国家记分卡的实用性，并强调了居民在领导气候意识卫生保健改进方面的重要作用。让受训者参与结构化评估可以加速机构朝着更可持续的围手术期实践的努力。

The global shift away from healthy, diverse, and sustainable diets threatens children’s health and futures. Although school gardens and home-grown school feeding can reconnect children with nutritious, sustainably produced food, these interventions are often implemented separately and with little attention to agrobiodiversity, which is a cornerstone for sustainability and healthy diets. Via a scoping review of 124 articles from 35 countries, we identified wide-ranging and complementary benefits of these interventions beyond health and education. The benchmark of the species used in these interventions against cultivated, predicted, and listed edible plants shows that agrobiodiversity is underused. Despite fragmented and incomplete evidence, our research shows that these interventions can jointly drive profound transformation. Realising this potential demands systemic shifts toward holistic, rights-based approaches that overcome surmountable barriers and build objective, sustainable, and resilient food systems delivering planet-friendly school meals.

全球远离健康、多样化和可持续饮食的趋势威胁着儿童的健康和未来。虽然学校菜园和自产学校供餐可以让儿童重新获得可持续生产的营养食物，但这些干预措施往往是单独实施的，很少关注农业生物多样性，而农业生物多样性是可持续性和健康饮食的基石。通过对来自35个国家的124篇文章的范围审查，我们确定了这些干预措施在健康和教育之外的广泛和互补效益。这些干预措施中使用的物种与栽培、预测和列出的可食用植物的基准表明，农业生物多样性未得到充分利用。尽管证据零散且不完整，但我们的研究表明，这些干预措施可以共同推动深刻的变革。要实现这一潜力，就需要系统性地转向以权利为基础的整体方法，克服可克服的障碍，建立客观、可持续和有弹性的粮食系统，提供对地球友好的校餐。

Background

As climate change accelerates, its impact on human health intensifies. For the health system to protect communities and effectively respond to climate-related shocks and stressors, climate adaptation should be prioritised. Although countries have made commitments to climate-resilient and sustainable health systems, their implementation remains understudied. The Western Cape province in South Africa, aff5cted by a severe drought in 2015–18 and extreme heat events, has emphasised health as a priority adaptation sector.

Methods

Through a policy document analysis and in-depth interviews, in this study, we investigated the factors influencing the implementation of climate adaptation for health in the Western Cape. The study comprised three interconnected analyses of responses to drought and heat. The first analysis involved assessment of the coherence of climate, environment, and health policies and revealed minimal connections at the national level, especially in relation to heat, and none at the provincial level. The second analysis highlighted the provincial health sector’s response to the 2017–18 drought, underscoring the importance of health-system software factors, such as values, knowledge, and relationships, in managing the response. The third analysis examined the governance of heat-related health risks and revealed fragmented local action despite a national heat health policy, with challenges linked to unclear responsibilities and inadequate contextualisation.

Findings

Collectively, this research shows that adaptive responses often emerge outside formal policies and are driven by informal practices and cross-sectoral collaboration between individuals and organisations.

Interpretation

Effective climate adaptation depends on context-specific, inclusive actions and the institutionalisation of learning to strengthen both individual and organisational adaptive capacity.

随着气候变化的加速，其对人类健康的影响也在加剧。为了使卫生系统保护社区并有效应对与气候有关的冲击和压力源，应优先考虑气候适应。尽管各国已对气候适应型和可持续的卫生系统作出承诺，但其实施情况仍未得到充分研究。南非西开普省在2015-18年遭受严重干旱和极端高温事件的影响，强调卫生是优先适应部门。方法本研究通过政策文件分析和深度访谈，调查影响西开普省实施气候适应健康的因素。这项研究包括对干旱和高温反应的三个相互关联的分析。第一次分析涉及对气候、环境和卫生政策的一致性进行评估，结果显示，在国家一级，特别是在供暖方面，它们之间的联系微乎其微，而在省一级则没有联系。第二项分析强调了省级卫生部门对2017-18年干旱的反应，强调了卫生系统软件因素（如价值观、知识和关系）在管理反应中的重要性。第三项分析检查了与热相关的健康风险的治理，并揭示了尽管有国家热健康政策，但地方行动零散，挑战与责任不明确和背景化不足有关。总的来说，这项研究表明，适应性反应往往出现在正式政策之外，并由非正式实践和个人与组织之间的跨部门合作驱动。有效的气候适应取决于具体环境的包容性行动和学习的制度化，以加强个人和组织的适应能力。

Background

Climate change presents a major challenge to health-care systems, particularly in low-income and middle-income countries such as Kenya. Health workers are key to leading the transition towards a sustainable, climate-resilient health-care system. This mixed-methods study explored the perceptions, knowledge, and roles of Kenyan health workers in mitigation and adaptation in health care.

Methods

An online questionnaire was used to assess the understanding of health workers regarding the impact of climate change on health, the health-care system’s role in emissions reduction and adaptation, and current practices. A subsequent focus group discussion delved deeper into the identified themes, with a particular focus on educating health workers to support climate action.

Findings

The questionnaire was completed by 118 health workers. Although the respondents recognised the health risks of climate change, financial constraints and insufficient training were major barriers to implementing sustainable practices. The focus group highlighted the need for practical, context-specific education to equip health workers with actionable knowledge and skills, while also fostering emotional resilience and ethical leadership.

Interpretation

We recommend co-creating educational programmes with communities and health workers, integrating climate–health modules into curricula, and using innovative approaches such as peer-led workshops and social media campaigns. These insights underscore the transformative potential of education in empowering health workers to lead Kenya’s transition to a sustainable, climate-resilient health-care system.

Background

Agricultural production is essential to human wellbeing; at the same time, it is scrutinised regarding its environmental externalities and sustainability in this changing world. Integrated crop–livestock systems (ICLS) offer a promising avenue for future agricultural systems. Taking China as the focus, this scoping review aims to uncover the contributions of ICLS to human wellbeing.

Methods

A total of 3671 studies related to ICLS were collected from four major electronic databases, and 166 papers were eventually included for formal analysis after a two-round screening process.

Findings

The findings reveal a growing interest in this topic over the past 5 years. Most of the included studies were conducted in eastern (26%) or northern (18%) China at micro scales such as field or farm scales. Two major forms of crop–livestock interaction were identified: using livestock waste to fertilise crops (54%) and feeding livestock with resources from crop systems (34%). In terms of the contributions of ICLS to human wellbeing, the included studies gave equal attention to the environmental (45%) and economic (45%) aspects of wellbeing, whereas less focus was placed on societal (10%) wellbeing. Notably, the positive effects of ICLS predominate in most cases—84% for environmental, 71% for economic, and 63% for societal wellbeing. In particular, using livestock waste to fertilise crops shows an overall more substantial positive contribution to human wellbeing when compared with other types of ICLS.

Interpretation

Our analysis indicates that ICLS holds great potential for improving human wellbeing under uncertain risks. To further facilitate its implementation, more research should focus on southwestern, central, and northwestern China and new practices of ICLS beyond farm scales should be explored. The societal effects of ICLS should also be studied. By benefiting human wellbeing, ICLS can contribute to the achievement of many Sustainable Development Goals including no poverty, zero hunger, gender equality, and life on land.

农业生产对人类福祉至关重要；与此同时，在这个不断变化的世界中，它的环境外部性和可持续性也受到了严格审查。作物-牲畜综合系统（ICLS）为未来的农业系统提供了一条有希望的途径。本研究以中国为研究焦点，旨在揭示ICLS对人类福祉的贡献。方法从四个主要的电子数据库中收集与ICLS相关的研究共3671篇，经过两轮筛选，最终纳入166篇论文进行正式分析。研究结果表明，在过去的5年里，人们对这个话题的兴趣越来越大。大多数纳入的研究是在中国东部（26%）或北部（18%）的微观尺度上进行的，如田地或农场规模。确定了作物-牲畜相互作用的两种主要形式：利用牲畜废物给作物施肥（54%）和用作物系统的资源喂养牲畜（34%）。就ICLS对人类福祉的贡献而言，纳入的研究对福祉的环境（45%）和经济（45%）方面给予了同等的关注，而对社会福祉的关注较少（10%）。值得注意的是，ICLS的积极影响在大多数情况下占主导地位——84%对环境，71%对经济，63%对社会福利。特别是，与其他类型的ICLS相比，利用牲畜废物为作物施肥对人类福祉的总体贡献更大。我们的分析表明，在不确定的风险下，ICLS具有改善人类福祉的巨大潜力。为进一步促进ICLS的实施，应将更多的研究重点放在中国的西南、中部和西北地区，并探索农场规模以外的ICLS新实践。ICLS的社会影响也应该被研究。ICLS造福人类福祉，有助于实现许多可持续发展目标，包括无贫困、零饥饿、性别平等和陆地生命。本项目由中国国家留学基金委资助。

Greenspace can promote health via diverse pathways. A common approach to assessing greenspace exposure is to estimate vegetation availability within buffers surrounding locations where people reside or spend time. However, no clear framework for informed buffer selection exists, and choices made show considerable heterogeneity, impeding evidence synthesis and causal inference. In this Personal View conducted by an interdisciplinary panel of experts, we aimed to establish a framework for informed buffer selection for epidemiological studies on greenspace. We began by reviewing available approaches for the selection of buffer types, which range from single fixed-location approaches to high-resolution mobility-based activity-space approaches, as well as different buffer sizes. We then summarised the determinants of buffer type and size selection including health outcomes and underlying mechanisms, study population, contextual factors, and data characteristics. Finally, based on these determinants, we developed recommendations for future research. Buffer type and size selection should be hypothesis driven, reflecting presumed greenspace–health mechanisms. Buffer selection should target activity-based approaches where feasible, and multiple buffer sizes should be tested. Overall, the assessment of greenspace exposure should shift from ad-hoc approaches to personalised, multiscale, and context-specific methods. We call for standardising and reporting the rationale for buffer selection to minimise bias and enhance comparability and evidence synthesis across studies.

绿色空间可以通过多种途径促进健康。评估绿地暴露的一种常用方法是估计人们居住或停留地点周围缓冲区内的植被可用性。然而，目前还没有明确的知情缓冲选择框架，所做的选择显示出相当大的异质性，阻碍了证据合成和因果推理。在这个由跨学科专家小组进行的个人观点中，我们的目标是建立一个框架，为绿色空间的流行病学研究提供知情的缓冲选择。我们首先回顾了选择缓冲区类型的可用方法，从单一的固定位置方法到基于高分辨率移动性的活动空间方法，以及不同的缓冲区大小。然后，我们总结了缓冲区类型和大小选择的决定因素，包括健康结果和潜在机制、研究人群、背景因素和数据特征。最后，基于这些决定因素，我们提出了未来研究的建议。缓冲区类型和大小的选择应该是假设驱动的，反映假定的绿色空间健康机制。在可行的情况下，缓冲区选择应该针对基于活动的方法，并且应该测试多个缓冲区大小。总体而言，绿色空间暴露的评估应从临时方法转向个性化、多尺度和特定环境的方法。我们呼吁对缓冲选择的基本原理进行标准化和报告，以尽量减少偏倚，增强研究之间的可比性和证据综合。

Background

Modern food systems contribute to environmental degradation, while prevailing unhealthy eating behaviours exacerbate the global cancer burden, creating a dual synergistic crisis for both planetary and human health. Investigating the impact of sustainable diets on cancer is therefore essential.

Methods

Following the 2020 PRISMA guidelines for reporting systematic reviews and meta-analysis, observational studies on cancer incidence and mortality among adults, assessing the sustainability of their diets using various metrics, were examined. Effect measures were pooled to compare the highest versus lowest adherence to sustainable dietary patterns. Summary effect estimates for cancer incidence and mortality were calculated using random-effects models. Subgroup analyses were conducted by sex, geographical region, study design, sustainability metric used, dietary assessment indexes reflecting sustainability, and cancer type. E-values were used to evaluate the robustness of associations against potential unmeasured confounding. The study was pre-registered in PROSPERO (ID CRD42024545102).

Findings

19 effect estimates from 17 studies, encompassing over 2·2 million participants, revealed a significant reduction in cancer incidence (hazard ratio 0·93, 95% CI 0·88−0·98, I² 84·67%) and cancer mortality (hazard ratio 0·88; 95% CI 0·85–0·92, I² 21·25%) associated with higher adherence to sustainable diets. Subgroup analyses indicated that the overall effect was modified by study design, sustainability metrics, and dietary assessment index.

Interpretation

These findings support evidence linking sustainable diets with reduced cancer incidence and mortality, underscoring their potential role in cancer prevention while providing concurrent environmental benefits. The notable variability in sustainability metrics highlights the need for standardised approaches in future research.

现代粮食系统加剧了环境退化，而普遍存在的不健康饮食行为加剧了全球癌症负担，给地球和人类健康造成了双重协同危机。因此，研究可持续饮食对癌症的影响至关重要。方法遵循2020年PRISMA报告系统评价和荟萃分析指南，对成人癌症发病率和死亡率的观察性研究进行了检查，使用各种指标评估其饮食的可持续性。研究人员将效果指标汇总起来，比较对可持续饮食模式坚持程度最高和最低的人群。使用随机效应模型计算癌症发病率和死亡率的总效应估计。按性别、地理区域、研究设计、使用的可持续性指标、反映可持续性的饮食评估指标和癌症类型进行亚组分析。e值用于评估关联对潜在未测量混杂因素的稳健性。该研究已在PROSPERO预注册（ID CRD42024545102）。来自17项研究的结果，包括超过220万参与者的效应估计，显示癌症发病率（风险比0.93,95% CI 0.88 - 0.98, I2 84.67%）和癌症死亡率（风险比0.88,95% CI 0.85 - 0.92, I2 21.25%）的显著降低与更高的可持续饮食依从性相关。亚组分析表明，总体效果受到研究设计、可持续性指标和饮食评估指数的影响。这些发现支持了将可持续饮食与降低癌症发病率和死亡率联系起来的证据，强调了它们在预防癌症方面的潜在作用，同时提供了环境效益。可持续性指标的显著变化凸显了在未来研究中采用标准化方法的必要性。
