This article presents the NURTURE framework, a curriculum tool designed in collaboration with an Indigenous artist to support educators in preparing future professionals to address global planetary crises. Methods The framework organises 35 curriculum concepts previously identified by stakeholders across 27 countries as relevant for entry-level nutrition and dietetics professionals. Drawing on holistic educational models and Indigenous worldviews that emphasise the interconnected relationships between humans and nature, researchers mapped the concepts to four domains from an existing model: Heart, Head, Hands, and Feet, via independent blinded analysis and a consensus-building workshop. Through a process of co-construction, an Indigenous artist then visualised these concepts using paint on canvas. Results The NURTURE framework (Nutrition professionals’ Understanding, Reflective values, Translational skills, Utilising systems thinking, Responsible leadership, and Evidence-based action) establishes values-led pedagogy (HEART—affective concepts) as the foundation for knowledge (HEAD—cognitive concepts), practical competence (HANDS—psychomotor concepts), and evidence-based action (FEET—agency concepts). The model prioritises diverse knowledge systems and systems thinking to develop the competencies needed to navigate complex food system trade-offs. Discussion The NURTURE framework aims to support nutrition and dietetics educators to cultivate planetary empathy through deep learning and whole-person pedagogical approaches, prioritising Indigenous values-based philosophies. This adaptable curriculum tool will be applied and refined across diverse geographical contexts globally to advance sustainable food systems and planetary health education.","引言 营养与饮食学专业人员在食品系统转型中至关重要；然而，高等教育中可持续食品系统与星球健康课程体系的整合仍不充分。本文介绍NURTURE框架，这是一种与一位原住民艺术家合作设计的课程工具，旨在支持教育者培养未来专业人员以应对全球星球危机。方法 该框架整理了此前由27个国家的利益相关者所确定的35个课程概念，这些概念被认为与入门级营养与饮食学专业人员相关。研究者借鉴整体性教育模式及强调人与自然相互关联的原住民世界观，通过独立盲法分析和共识构建研讨会，将这些概念映射到现有模型中的四个领域：心（Heart）、脑（Head）、手（Hands）和足（Feet）。通过共同构建过程，一位原住民艺术家随后使用画布上的绘画将这些概念可视化。结果 NURTURE框架（营养专业人员的理解、反思性价值观、转化技能、运用系统思维、负责任领导力和循证行动）将价值观导向的教学法（心——情感性概念）确立为知识（脑——认知性概念）、实践能力（手——心理运动性概念）和循证行动（足——能动性概念）的基础。该模型优先考虑多元知识体系和系统思维，以培养应对复杂食品系统权衡所需的能力。讨论 NURTURE框架旨在支持营养与饮食学教育者通过深度学习和全人教学法培养星球共情，并优先重视原住民基于价值观的哲学。这一可调整的课程工具将在全球不同地理背景下应用和完善，以推进可持续食品系统和星球健康教育。",null,"Frontiers in Sustainable Food Systems","2026-09-11T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"该文为营养与膳食学教育课程框架研究，属医学营养教育范畴，与三农、农业信息化、智慧农业等主题无关，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23,24],"可持续食物系统","营养教育","行星健康","课程框架",[],{"status":27,"locked":14,"version":28,"method":29,"evidence":30},"needs_review","2026-10-22.2","rules",{"candidates":31,"agricultural_evidence":14,"reason":47},[32,41],{"code":33,"score":34,"supported":35,"title":36,"abstract":37,"tags":40},"I2",6,true,[],[38,39],"深度学习","deep learning",[],{"code":42,"score":43,"supported":14,"title":44,"abstract":45,"tags":46},"E2",1,[],[],[21],"农业相关性需要复核",[49,50],"可持续食物系统 营养教育 行星健康 课程框架","可持续食物系统 营养教育","可持续食物系统营养教育行星健康课程框架-2294","10.3389\u002Ffsufs.2026.1882185",{"doi":52,"openalex_id":54,"authors":55,"venue":10,"cited_by_count":15,"oa_url":6,"card":73,"direction":77,"ingested_from":79},"W7212282852",[56,58,60,62,65,67,70],{"name":57,"orcid":9},"Liza Barbour",{"name":59,"orcid":9},"Devinia Wainwright",{"name":61,"orcid":9},"Sarah Browne",{"name":63,"orcid":64},"Clare Pettinger","https:\u002F\u002Forcid.org\u002F0000-0001-7182-9463",{"name":66,"orcid":9},"Jessica Wegener",{"name":68,"orcid":69},"Tracy Everitt","https:\u002F\u002Forcid.org\u002F0000-0002-9483-4828",{"name":71,"orcid":72},"Liesel Carlsson","https:\u002F\u002Forcid.org\u002F0000-0001-8857-9608",{"tldr":74,"method":75,"finding":76,"direction":77,"opportunity":78},"提出NURTURE课程框架，用原住民整体观培养营养专业人员的可持续食物系统能力。","基于27国35个课程概念，经盲审映射与共识工作坊，由原住民艺术家视觉化。","以价值观为根基，构建心、脑、手、足四域课程，强调系统思维与行星共情。","其他","可将该框架本土化并实证评估，探索数字工具支持下的课程实施与能力测评。","openalex","2026-09-13T23:30:07.322177Z",{"total":34,"page":43,"page_size":34,"items":82},[83,163,236,297,367,429],{"id":84,"title":85,"url":86,"summary":87,"summary_zh":88,"content":9,"source_name":10,"source_url":86,"published_at":89,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":90,"score_detail":91,"sources":98,"tags":100,"primary_topic":105,"secondary_topics":111,"classification":112,"search_phrases":137,"slug":140,"view_count":15,"doi":141,"paper":142,"created_at":162},4980,"Creating common ground: integrating transformative agroecology and extension research in undergraduate education","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1882768","This paper examines the Agroecology Extension (AX) summer Research Fellowship at the University of Vermont, a 5-year USDA-funded undergraduate program that intentionally integrated extension research with agroecology education within a land-grant university context. Drawing on predominantly qualitative evaluation of five cohorts (2021–2025, n = 47), we identify enabling and constraining pedagogical factors for creating common ground between two domains that remain institutionally separated at most land-grant universities. The study contributes to the emerging signature pedagogy for sustainable food systems education by documenting how three interconnected pedagogical dynamics—integrating political agroecology with extension, centering equity as a sustained commitment, and supporting participatory knowledge co-creation with students—shaped program design and evolution across 5 years. Findings demonstrate that transformative education at the intersection of agroecology and extension requires explicit engagement with the political dimensions of agroecology and extension history, relational infrastructure for equity work, and deliberate structures for co-learning. This case study offers practical pedagogical insights for land-grant universities seeking to develop sustainable programs that bridge agroecology and extension while preparing graduates to address complex agricultural and food systems challenges.","本文考察了佛蒙特大学的农业生态学推广（Agroecology Extension, AX）暑期研究奖学金项目。该项目由美国农业部资助，为期五年，是一项本科生项目，在赠地大学（land-grant university）语境下有意将推广研究与农业生态学教育相结合。基于对五届学员（2021—2025年，n = 47）的以定性为主的评估，我们识别了在大多数赠地大学中仍处于制度性分离状态的两个领域之间建立共同基础（common ground）的促进性与制约性教学因素。本研究通过记录三种相互关联的教学动态——将政治农业生态学与推广相结合、将公平作为持续承诺加以中心化、以及支持与学生共同进行参与式知识共创——如何在五年间塑造了项目设计与演变，为可持续食物系统教育的新兴标志性教学法（signature pedagogy）作出了贡献。研究结果表明，在农业生态学与推广的交汇处开展变革性教育，需要明确介入农业生态学的政治维度与推广历史、建立支持公平工作的关系性基础设施，以及为共同学习设计有意的制度结构。本案例研究为那些寻求开发可持续项目、以弥合农业生态学与推广之间鸿沟、同时培养毕业生应对复杂农业与食物系统挑战的赠地大学提供了实践性教学启示。","2026-10-14T00:00:00Z",65,{"impact":92,"substance":93,"depth":94,"authority":95,"freshness":96,"relevant":43,"comment":97},8,18,17,13,9,"美国赠地大学农业生态学与推广教育融合的五年期本科项目案例研究，方法扎实但属境外教育实践，对国内三农信息化仅有间接参考价值。",[99],{"name":10,"url":86},[21,101,102,103,104],"农业教育","农业推广","生态农业","参与式研究",{"code":106,"slug":107,"name":108,"path":109,"parent_code":110},"H6","biodiversity","生态保护与生物多样性","\u002Ftopic\u002Fenvironment\u002Fbiodiversity","H",[],{"status":113,"locked":14,"version":28,"method":29,"evidence":114},"classified",{"candidates":115,"agricultural_evidence":35},[116,123,127,132],{"code":106,"score":117,"supported":35,"title":118,"abstract":120,"tags":122},14,[119],"agroecology",[121,119],"农业生态",[],{"code":42,"score":43,"supported":14,"title":124,"abstract":125,"tags":126},[],[],[21],{"code":128,"score":43,"supported":14,"title":129,"abstract":130,"tags":131},"G1",[],[],[102],{"code":133,"score":43,"supported":14,"title":134,"abstract":135,"tags":136},"H8",[],[],[103],[138,139],"佛蒙特大学 农业推广 生态农业","可持续食物系统 参与式研究 农业推广 农业教育","佛蒙特大学农业推广生态农业-4980","10.3389\u002Ffsufs.2026.1882768",{"doi":141,"openalex_id":143,"authors":144,"venue":10,"cited_by_count":15,"oa_url":156,"card":157,"direction":77,"ingested_from":79},"W7221806502",[145,148,151,153],{"name":146,"orcid":147},"Karen L.

In India, rising income levels and lifestyle changes have accelerated this shift. This study explores the factors that affect consumers’ willingness to buy organic food by examining food safety concerns, natural content, nutritional concerns, health consciousness, attitude, and religion. Methods The survey was conducted among 256 potential consumers in the Delhi NCR region using convenience sampling. A combined methodology was utilised, incorporating partial least squares structural equation modelling (PLS-SEM) alongside fuzzy-set qualitative comparative analysis (fsQCA) to gain both symmetric and asymmetric insights. PLS-SEM was employed to analyse the direct effects and validate the theoretical framework. Furthermore, fsQCA was employed to explore the necessary conditions and configurations of variables that lead to high purchase intention. Results PLS-SEM results demonstrate that concerns related to food safety, health consciousness, and nutritional concerns significantly impact purchase intentions. The fsQCA results reveal that health consciousness and attitude are necessary conditions, while various combinations serve as sufficient configurations, thereby supporting the principle of equifinality. Discussion These findings suggest that consumers’ intentions are shaped not only by individual drivers but also by the complex interplay of multiple factors.

The academic community has long held theoretical disagreements on this issue between static efficiency standards and dynamic equilibrium perspectives, and no integrated explanatory framework that combines economic logic, social context and temporal dimensions has yet been established. Drawing on new institutional economics, economic sociology, family life-cycle theory and intergenerational transmission theory, and proceeding through theoretical deduction, institutional context analysis and secondary evidence from policy documents, official statistics and literature, this paper develops a triple-constraint dynamic equilibrium framework for the moderate-scale operation of family farms in China; its purpose is explanatory rather than estimative, since no uniform optimal scale is defensible across heterogeneous regional endowments, crop systems, service conditions and family structures. The framework holds that moderate scale is not a fixed value set externally but a dynamic equilibrium interval of operating scale: the economic-efficiency constraint sets its lower bound, the social-embeddedness constraint sets its upper bound, and the intergenerational-sustainability constraint operates as an independent temporal condition that also moderates the position and width of the interval as the family life cycle and succession arrangements change. Seen thus, the factor-market, organisational-coordination and temporal-dimension failures observable in practice appear as three structural tensions that jointly compress the feasible interval and constrain the contribution of family farms to sustainable food-system goals. The contribution lies in bringing social embeddedness and intergenerational sustainability into the analysis of moderate scale, moving beyond a single-efficiency account and offering an integrated explanatory framework for the evolution of family-farm scale in transition economies with fragmented landholdings and household-centred production. The framework applies directly to family farms and other family-centred operations; its three constraints are analytically general, whereas their relative binding strength, the interval's position and the associated policy instruments remain conditional on the institutional environment, particularly China's collective land ownership and household contract responsibility system, so that its reference value for other transition economies is conditional rather than universal.","可持续食物系统的转型必须协调生产效率与供给韧性同小农生计保护之间的关系，而对于人口众多、耕地有限的经济体而言，这种协调在很大程度上取决于如何理解与组织家庭农场的经营规模。学术界长期以来在这一问题上存在理论分歧，表现为静态效率标准与动态均衡视角之间的对立，且尚未建立起一个将经济逻辑、社会情境与时间维度相结合的综合解释框架。本文借鉴新制度经济学、经济社会学、家庭生命周期理论与代际传承理论，通过理论推演、制度情境分析以及来自政策文件、官方统计与文献的二手证据，构建了中国家庭农场适度规模经营的三重约束动态均衡框架；其目的在于解释而非估算，因为在异质的区域禀赋、作物体系、服务条件与家庭结构之间，并不存在一个统一的最优规模。该框架认为，适度规模并非由外部设定的固定数值，而是经营规模的一个动态均衡区间：经济效率约束设定其下限，社会嵌入性约束设定其上限，而代际可持续性约束则作为独立的时间条件发挥作用，并随着家庭生命周期与继承安排的变化调节该区间的位置与宽度。由此观之，实践中可观察到的要素市场、组织协调与时间维度失灵，表现为三种结构性张力，它们共同压缩了可行区间，并制约了家庭农场对可持续食物系统目标的贡献。本文的贡献在于将社会嵌入性与代际可持续性纳入适度规模分析，超越单一效率解释，并为土地细碎化、以家庭为中心生产的转型经济体提供家庭农场规模演变的综合解释框架。该框架直接适用于家庭农场及其他以家庭为中心的经营活动；其三重约束在分析上具有一般性，而它们的相对约束强度、区间的位置以","2026-10-05T00:00:00Z",73,{"impact":199,"substance":306,"depth":93,"authority":95,"freshness":13,"relevant":43,"comment":307},20,"理论性论文，提出三重约束动态均衡框架，对家庭农场适度规模经营有解释力，但偏学术、政策落地性有限。",[309],{"name":10,"url":300},[311,21,312,313,314],"家庭农场","土地制度","适度规模经营","代际传承",{"code":316,"slug":317,"name":318,"path":319,"parent_code":320},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",[],{"status":113,"locked":14,"version":28,"method":29,"evidence":323},{"candidates":324,"agricultural_evidence":35},[325,331],{"code":316,"score":326,"supported":35,"title":327,"abstract":328,"tags":330},7,[],[311,329],"smallholder",[311],{"code":42,"score":43,"supported":14,"title":332,"abstract":333,"tags":334},[],[],[21],[336,337],"家庭农场 适度规模经营","中国 家庭农场 可持续食物系统","家庭农场适度规模经营-4203","10.3389\u002Ffsufs.2026.1937247",{"doi":339,"openalex_id":341,"authors":342,"venue":10,"cited_by_count":15,"oa_url":300,"card":361,"direction":233,"ingested_from":79},"W7219629671",[343,346,348,350,352,355,357,359],{"name":344,"orcid":345},"Ning Ding","https:\u002F\u002Forcid.org\u002F0000-0001-5618-6359",{"name":347,"orcid":9},"Jingjing Wang",{"name":349,"orcid":9},"Yong Xia",{"name":351,"orcid":9},"Fuhong Wang",{"name":353,"orcid":354},"Guirong Wang","https:\u002F\u002Forcid.org\u002F0009-0000-3917-003X",{"name":356,"orcid":9},"Yi Lyu",{"name":358,"orcid":9},"Ziyang Wang",{"name":360,"orcid":9},"Yijuan Yang",{"tldr":362,"method":363,"finding":364,"direction":233,"opportunity":365},"构建三重约束动态均衡框架，解释中国家庭农场适度规模经营逻辑与优化路径。","新制度经济学、经济社会学、家庭生命周期与代际传递理论，结合政策与统计数据。","适度规模是动态均衡区间：经济效率定下限，社会嵌入定上限，代际可持续为时间条件。","可实证测度三重约束的区间边界，并探究数字技术如何缓解要素市场与组织协调失灵。","2026-10-05T23:30:07.088111Z",{"id":368,"title":369,"url":370,"summary":371,"summary_zh":372,"content":9,"source_name":10,"source_url":370,"published_at":373,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":374,"score_detail":375,"sources":378,"tags":380,"primary_topic":9,"secondary_topics":385,"classification":386,"search_phrases":404,"slug":407,"view_count":15,"doi":408,"paper":409,"created_at":428},3813,"Pioneering AI adoption in downstream food service: structural drivers of operator intentions and implications for sustainable food systems","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1930406","Background \u002F Introduction Integrating digital innovations into downstream food service operations is essential for transitioning toward sustainable food systems. This study investigates the factors influencing restaurant employees’ and operators’ intentions to adopt artificial intelligence (AI) within the Taiwanese restaurant sector. Methods The study utilizes survey data collected from 176 food service participants. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) based on an extended Technology Acceptance Model (TAM), which incorporates subjective norms, operational compatibility, and facilitating conditions. Results The findings confirm classic TAM axioms and demonstrate the impact of external socio-technical factors. Subjective norms exert a strong influence on both perceived usefulness and perceived ease of use, with the greatest impact on perceived usefulness. Additionally, system compatibility positively influences perceived ease of use while showing no significant effect on perceived usefulness, whereas facilitating conditions produce non-significant relationships with both core TAM dimensions. Finally, operator attitudes correlate positively with utility and ease of use perceptions, with perceived usefulness acting as the primary factor that strongly predicts the intention to use AI solutions. Discussion \u002F Conclusion While the study focuses on adoption intentions rather than actual waste reduction, the findings offer practical implications for scaling up digital tools. These tools can indirectly support inventory optimization and resource efficiency within commercial food service workflows.","背景\u002F引言：将数字创新融入下游餐饮服务运营，对于向可持续食品系统转型至关重要。本研究探讨了影响台湾餐饮业员工和经营者采用人工智能（AI）意向的因素。方法：本研究利用从176名餐饮服务参与者收集的调查数据。基于扩展的技术接受模型（TAM），该模型纳入了主观规范、运营兼容性和便利条件，采用偏最小二乘结构方程模型（PLS-SEM）对数据进行分析。结果：研究结果证实了经典TAM公理，并展示了外部社会技术因素的影响。主观规范对感知有用性和感知易用性均有强烈影响，其中对感知有用性的影响最大。此外，系统兼容性正向影响感知易用性，而对感知有用性无显著影响，而便利条件与两个核心TAM维度均呈现非显著关系。最后，经营者态度与效用和易用性感知呈正相关，其中感知有用性是强烈预测使用AI解决方案意向的主要因素。讨论\u002F结论：虽然本研究聚焦于采用意向而非实际浪费减少，但研究结果为扩大数字工具的应用提供了实践启示。这些工具可以在商业餐饮服务工作流程中间接支持库存优化和资源效率。","2026-09-29T00:00:00Z",63,{"impact":92,"substance":93,"depth":376,"authority":95,"freshness":96,"relevant":43,"comment":377},15,"基于扩展TAM模型对台湾餐饮从业者AI采纳意愿的实证研究，方法规范、数据可靠，但样本仅176人且聚焦采纳意愿而非实际减废效果，属细分领域学术进展。",[379],{"name":10,"url":370},[381,382,21,383,384],"智慧农业","农业人工智能","餐饮数字化","技术接受模型",[],{"status":27,"locked":14,"version":28,"method":29,"evidence":387},{"candidates":388,"agricultural_evidence":14,"reason":47},[389,395,399],{"code":33,"score":390,"supported":35,"title":391,"abstract":392,"tags":394},4,[],[393],"artificial intelligence",[382],{"code":42,"score":43,"supported":14,"title":396,"abstract":397,"tags":398},[],[],[21],{"code":400,"score":43,"supported":14,"title":401,"abstract":402,"tags":403},"I1",[],[],[381],[405,406],"台湾 餐饮业 AI 采纳","餐饮从业者 人工智能 采纳意愿","台湾餐饮业AI采纳-3813","10.3389\u002Ffsufs.2026.1930406",{"doi":408,"openalex_id":410,"authors":411,"venue":10,"cited_by_count":15,"oa_url":422,"card":423,"direction":233,"ingested_from":79},"W7214701689",[412,415,418,420],{"name":413,"orcid":414},"Massoud Moslehpour","https:\u002F\u002Forcid.org\u002F0000-0001-8808-2407",{"name":416,"orcid":417},"Hanif Rizaldy","https:\u002F\u002Forcid.org\u002F0000-0002-9181-5592",{"name":419,"orcid":9},"Ifat Batul",{"name":421,"orcid":9},"Chen-Chih John Yuan","https:\u002F\u002Fwww.frontiersin.org\u002Fjournals\u002Fsustainable-food-systems\u002Farticles\u002F10.3389\u002Ffsufs.2026.1930406\u002Fpdf",{"tldr":424,"method":425,"finding":426,"direction":233,"opportunity":427},"基于扩展TAM模型，分析台湾餐饮从业者采用AI的意向及影响因素。","对176名餐饮参与者问卷调查，用PLS-SEM分析扩展技术接受模型。","主观规范显著影响感知有用性和易用性，感知有用性是采用AI意向的首要预测因素。","可延伸至农业下游食品服务场景，探究AI采用意向如何转化为实际减损与资源效率提升。","2026-09-30T23:30:07.092904Z",{"id":430,"title":431,"url":432,"summary":433,"summary_zh":434,"content":9,"source_name":435,"source_url":432,"published_at":436,"category":12,"cover_url":9,"hotness":13,"is_selected":35,"score":437,"score_detail":438,"sources":442,"tags":444,"primary_topic":449,"secondary_topics":454,"classification":455,"search_phrases":467,"slug":470,"view_count":326,"doi":471,"paper":472,"created_at":503},3663,"China’s changing diets improve human health but increase environmental pressures","https:\u002F\u002Fdoi.org\u002F10.1038\u002Fs43247-026-04063-0","Understanding how dietary transitions shape environmental and health outcomes across socio-economic and spatial contexts is essential for informing sustainable food system transformations. Here we investigate evolving trade-offs between environmental and health outcomes during urban and rural dietary transitions in China from 1990 to 2021, and examines how these trade-offs vary with regional development levels. Here we show that China’s dietary transition has shifted from initial health and environment synergies to trade-offs, with rising environmental pressures alongside health gains. These trade-offs are more pronounced in regions with a human development index above 0.55. Urban and rural dietary transitions show broadly similar patterns but differ in trade-off progression and associated risks: urban diets are linked to faster health improvements with rising environmental impacts, while rural diets show slower health gains alongside disproportionately high environmental burdens. Scenario analyses indicate that integrating precision agriculture, food waste reduction, and dietary optimization can substantially reduce both health and environmental burdens while narrowing urban and rural inequalities. China’s dietary transitions improve health outcomes but increase environmental pressures, with faster health gains but rising environmental impacts in urban areas and slower health gains yet higher environmental burdens in rural areas, according to analysis combining environmental and health indicators and scenario modeling","理解饮食结构转变如何在不同社会经济和空间背景下影响环境与健康结果，对于推动可持续食物系统转型至关重要。本文研究了1990年至2021年中国城乡饮食结构转变过程中环境与健康结果之间不断演变的权衡关系，并考察了这些权衡关系如何随区域发展水平而变化。研究表明，中国的饮食结构转变已从初期健康与环境的协同效应转向权衡关系，环境压力与健康收益同步上升。这些权衡关系在人类发展指数高于0.55的地区更为显著。城乡饮食结构转变呈现总体相似的模式，但在权衡关系的演进和相关风险方面存在差异：城市饮食与健康改善速度较快但环境影响上升相关，而农村饮食则表现为健康收益较慢且环境负担不成比例地偏高。情景分析表明，整合精准农业、减少食物浪费和饮食优化可大幅降低健康和环境负担，同时缩小城乡不平等。综合环境与健康指标及情景模型的分析表明，中国饮食结构转变改善了健康结果，但增加了环境压力，城市地区健康收益较快但环境影响上升，农村地区健康收益较慢但环境负担更高。","Communications Earth & Environment","2026-09-25T00:00:00Z",85,{"impact":439,"substance":440,"depth":93,"authority":117,"freshness":92,"relevant":43,"comment":441},22,23,"基于1990-2021年中国城乡膳食转型的环境与健康权衡分析，数据扎实、结论明确，对可持续食物系统与农业政策有参考价值。",[443],{"name":435,"url":432},[445,21,446,447,448],"精准农业","食物浪费","膳食转型","城乡差异",{"code":400,"slug":450,"name":451,"path":452,"parent_code":453},"smart-agriculture","智慧农业总论","\u002Ftopic\u002Fdigital-agriculture\u002Fsmart-agriculture","I",[],{"status":113,"locked":14,"version":28,"method":29,"evidence":456},{"candidates":457,"agricultural_evidence":35},[458,463],{"code":400,"score":326,"supported":35,"title":459,"abstract":460,"tags":462},[],[445,461],"precision agriculture",[445],{"code":42,"score":269,"supported":14,"title":464,"abstract":465,"tags":466},[],[],[21,446],[468,469],"中国 膳食转型 环境影响","精准农业 食物浪费 膳食优化","中国膳食转型环境影响-3663","10.1038\u002Fs43247-026-04063-0",{"doi":471,"openalex_id":473,"authors":474,"venue":435,"cited_by_count":15,"oa_url":495,"card":496,"direction":502,"ingested_from":79},"W7167885329",[475,477,480,483,486,489,492],{"name":476,"orcid":9},"Yufan Shi",{"name":478,"orcid":479},"Fan Ning","https:\u002F\u002Forcid.org\u002F0009-0006-6198-8253",{"name":481,"orcid":482},"Miaomiao Liu","https:\u002F\u002Forcid.org\u002F0000-0002-9043-3584",{"name":484,"orcid":485},"Jie Yang","https:\u002F\u002Forcid.org\u002F0000-0003-4801-7162",{"name":487,"orcid":488},"Wen Fang","https:\u002F\u002Forcid.org\u002F0000-0001-7748-6772",{"name":490,"orcid":491},"Zongwei Ma","https:\u002F\u002Forcid.org\u002F0000-0003-0257-5695",{"name":493,"orcid":494},"Jun Bi","https:\u002F\u002Forcid.org\u002F0000-0001-9591-4806","https:\u002F\u002Fwww.nature.com\u002Farticles\u002Fs43247-026-04063-0_reference.pdf",{"tldr":497,"method":498,"finding":499,"direction":500,"opportunity":501},"分析1990-2021年中国城乡膳食转型对健康与环境的权衡，并模拟优化路径。","结合环境与健康指标及情景模拟，分析城乡膳食转型与区域发展差异。","膳食转型由健康环境协同转为权衡，城镇健康改善快但环境压力升，农村健康慢而环境负担高。","农业绿色发展与碳","可探究精准农业、减损与膳食优化组合在缩小城乡健康环境不平等中的落地机制与政策路径。","智慧农业 \u002F 农业物联网","2026-09-28T23:30:10.187347Z"]
