However, its environmental and economic outcomes may vary substantially across farming contexts, particularly in smallholder and Indigenous systems. This study evaluated sustainability trade-offs associated with agricultural modernization in 88 Indigenous Mapuche smallholder farms in southern Chile. A Modernization Index (MI) was developed to represent different levels of technological intensification. Environmental performance was assessed through Life Cycle Assessment (LCA) in 40 farms with complete inventory data, while productive and economic performance was evaluated using wheat productivity, profit, and benefit-cost ratio indicators. Higher MI values were consistently associated with greater environmental impacts in all evaluated categories except land competition. Climate-change impacts ranged from 60 to 871 kg CO 2 -eq t −1 of wheat and cumulative energy demand from 693 to 8,421 MJ t −1 . Wheat productivity showed a statistically significant but weak positive association with MI (adjusted R 2 = 0.05, p = 0.02), whereas profit showed no significant relationship with modernization. The benefit-cost ratio showed a weak negative association with MI (adjusted R 2 = 0.03, p = 0.05). These findings indicate that the modest productivity gains observed along the modernization gradient were accompanied by higher environmental burdens and did not translate into improved economic performance. The results highlight the importance of evaluating agricultural development pathways through integrated environmental and economic indicators and within the specific socioecological conditions in which technological change occurs.","农业现代化被广泛推广为实现生产力提升、改善农村生计以及增强粮食生产系统可持续性的途径。然而，其环境和经济结果在不同农业情境下可能存在显著差异，尤其是在小农和原住民系统中。本研究评估了智利南部88个马普切（Mapuche）原住民小农农场中与农业现代化相关的可持续性权衡。研究构建了现代化指数（Modernization Index, MI），用以表征不同水平的技术集约化程度。环境绩效通过生命周期评价（Life Cycle Assessment, LCA）对40个具有完整清单数据的农场进行评估，而生产与经济绩效则采用小麦生产力、利润和效益成本比指标进行评价。较高的MI值在所有评估类别中均与更大的环境影响相关，但土地竞争类别除外。气候变化影响范围为每吨小麦60至871千克二氧化碳当量（kg CO₂-eq t⁻¹），累计能源需求范围为每吨693至8,421兆焦耳（MJ t⁻¹）。小麦生产力与MI之间呈现统计显著但较弱的相关性（调整后R² = 0.05，p = 0.02），而利润与现代化水平之间无显著关系。效益成本比与MI呈弱负相关（调整后R² = 0.03，p = 0.05）。这些研究结果表明，沿现代化梯度观察到的适度生产力提升伴随着更高的环境负担，且并未转化为经济绩效的改善。研究结果强调了在技术变革发生的特定社会生态条件下，通过综合环境与经济指标评估农业发展路径的重要性。",null,"Frontiers in Sustainable Food

Ngororero District Case (2020–2025).METHODOLOGY: This descriptive study was carried out in Ngororero District. Both qualitative and quantitative methods were used in the investigation. 329 smallholder farming \u002FMembers of cooperatives were sampled by only 290 respondents’ responses were taken for anlaysis.Primary data were collected through structured questionnaires and interview. Quantitative data was analyzed using descriptive statistics with the aid of SPSS software, while qualitative data was subjected to thematic content analysis.RESULTS: The findings demonstrated that 100% farmers agreed that they adopted tarrace farming practices, 94.9% adopted agroforestry practices and 92.3% adopted climate-Smart Agriculture practices to enhance crop yields in Ngororero district. Furtemore, the findings revealed the levels of farmers' adoption of of sustainable farming practices was high by 62.4% of the farmers’ responses and level of crop yields is indicated by the Crop yield per area (measured in tons per hectare), increased harvest weight, value of crop production per household, Benefit-Cost Ratio of production and High-Yield Seed Varieties as well as Input efficiency specifically Water Use Efficiency and Fertilizer Use Efficiency. Moreover, the study found out that 83.7% of variation in crop yield enhancement in Ngororero District is explained by sustainable farming practices adoption.CONCLUSIONS AND RECOMMENDATIONS: Conclusively, The development of mixed farming (crops and livestock) has improved nutrient cycling, with farmers employing manure to improve soil quality and yields. The study findings recommend that policy makers and stakeholders prioritise support for SFP adoption through comprehensive agricultural policies, capacity-building initiatives, and investment in agricultural research and development to contribute to achieving the sustainable development goals, particularly goal related to zero hunger and goal 12 related to the responsible consumption and production.","目的：探讨采用可持续农业实践对提高卢旺达作物产量的影响。以恩戈罗雷罗县为例（2020—2025年）。方法：本描述性研究在恩戈罗雷罗县开展。研究采用定性与定量相结合的方法。共抽取329名小农户\u002F合作社成员为样本，仅对290名受访者的答复纳入分析。原始数据通过结构化问卷和访谈收集。定量数据借助SPSS软件采用描述性统计进行分析，定性数据则进行主题内容分析。结果：研究结果表明，100%的农民认同其采用了梯田耕作实践，94.9%采用了农林业实践，92.3%采用了气候智能型农业实践，以提高恩戈罗雷罗县的作物产量。此外，研究结果显示，农民对可持续农业实践的采用水平较高，62.4%的农民答复表明了这一点；作物产量水平则通过单位面积作物产量（以吨\u002F公顷计量）、收获重量增加、每户作物产值、生产效益成本比、高产种子品种以及投入效率（特别是水分利用效率和肥料利用效率）等指标体现。此外，研究发现，恩戈罗雷罗县作物产量提升的83.7%变异可由可持续农业实践的采用来解释。结论与建议：综上，混合农业（作物与畜牧）的发展改善了养分循环，农民利用粪肥改善土壤质量和产量。研究结果建议，政策制定者和利益相关方应通过综合性农业政策、能力建设举措以及对农业研发的投资，优先支持可持续农业实践（SFP）的采用，以助力实现可持续发展目标，特别是与零饥饿相关的目标以及与水负责任消费和生产相关的目标12。","Zenodo (CERN European Organization for Nuclear Research)","2026-10-16T00:00:00Z",65,{"impact":17,"substance":19,"depth":170,"authority":17,"freshness":118,"relevant":21,"comment":171},14,"基于卢旺达县域调查的实证论文，数据具体但影响限于区域，可作为可持续农业国际案例参考。",[173],{"name":166,"url":163},[175,26,176,177,178],"小农户","作物产量","气候智慧农业","卢旺达",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":182},{"candidates":183,"agricultural_evidence":46},[184,188,195,202,209,214,220,226,230],{"code":31,"score":20,"supported":46,"title":185,"abstract":186,"tags":187},[],[175,53],[175],{"code":189,"score":58,"supported":46,"title":190,"abstract":191,"tags":194},"C",[],[192,193],"畜牧","livestock",[],{"code":196,"score":58,"supported":46,"title":197,"abstract":198,"tags":201},"F3",[],[199,200],"肥料","fertilizer",[],{"code":203,"score":58,"supported":46,"title":204,"abstract":205,"tags":208},"H2",[],[206,207],"土壤","soil",[],{"code":72,"score":210,"supported":46,"title":211,"abstract":212,"tags":213},4,[],[26],[26],{"code":215,"score":66,"supported":46,"title":216,"abstract":217,"tags":219},"I1",[],[218],"smart agriculture",[],{"code":221,"score":66,"supported":46,"title":222,"abstract":223,"tags":225},"J1",[],[224],"农业政策",[],{"code":65,"score":21,"supported":14,"title":227,"abstract":228,"tags":229},[],[],[177],{"code":231,"score":21,"supported":14,"title":232,"abstract":233,"tags":234},"I3",[],[],[176],[236,237],"卢旺达 Ngororero 可持续农业","小农户 气候智慧农业 产量","卢旺达Ngororero可持续农业-5146","10.5281\u002Fzenodo.23421082",{"doi":239,"openalex_id":241,"authors":242,"venue":166,"cited_by_count":95,"oa_url":163,"card":245,"direction":250,"ingested_from":102},"W7222451055",[243],{"name":244,"orcid":9},"Dr. Richard MIND'JE UWAMUTARAMBIRWA Clémence",{"tldr":246,"method":247,"finding":248,"direction":100,"opportunity":249},"研究卢旺达Ngororero地区采用可持续耕作方式对作物增产的影响。","对290户小农合作社成员问卷调查，用SPSS描述统计与主题内容分析。","可持续耕作采用率高，可解释83.7%的产量提升变异。","可结合遥感与地块数据量化可持续耕作对产量的因果效应，并拓展到碳汇与养分循环评估。","智慧农业 \u002F 农业物联网","2026-10-17T23:30:08.423023Z",{"id":253,"title":254,"url":255,"summary":256,"summary_zh":257,"content":9,"source_name":10,"source_url":255,"published_at":258,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":259,"score_detail":260,"sources":263,"tags":265,"primary_topic":269,"secondary_topics":270,"classification":271,"search_phrases":289,"slug":292,"view_count":95,"doi":293,"paper":294,"created_at":320},4482,"Development and validation of a multidimensional behavioural change index and its application to farmer producer organisations in India: implications for sustainable smallholder food systems","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1915367","Realising the Sustainable Development Goals in ending poverty (SDG 1), achieving zero hunger through sustainable agriculture (SDG 2), and reducing inequalities (SDG 10) hinges on the adaptive capacity of smallholder farmers, and Farmer Producer Organisations (FPOs) are widely promoted to strengthen it, yet their evaluation has concentrated on short-term economic gains, neglecting the behavioural transformation that sustains improvement and underpins resilient food systems, and limited validated multidimensional instruments are available to measure such behavioural differences across farmers. This study developed a Behavioural Change Index (BCI) and applied it to examine the association between FPO membership and farmer behvioural status in Odisha, India. An initial pool of 142 items was refined to 89 items across twelve theoretically grounded, expert-weighted dimensions through relevancy analysis by an 80-member expert panel, reliability testing, exploratory factor analysis, confirmatory factor analysis, composite reliability, average variance extracted, measurement invariance, discriminant validity and common-method-bias assessment, after which the index was applied to 300 FPO members and 100 non-members, with selection bias addressed through propensity-score matching, inverse-probability weighting, kernel and full matching, doubly-robust estimation and E-value sensitivity analysis. The BCI demonstrated excellent reliability (Cronbach’s α = 0.95), a clean twelve-factor structure explaining 68.3% of variance, and satisfactory discriminant validity; members scored significantly higher across all twelve dimensions(Cohen’s d = 1.29–2.21) and the raw advantage of 22.12 points remained robust after matching (19.34 points; doubly-robust ATT = 19.71; E -value = 6.69), indicating minimal sensitivity to unmeasured confounding. The cross-sectional study thus delivers both a psychometrically supported instrument and robust observational evidence of differences in behavioural status between FPO members and non-members after adjustment for observed covariates. By rendering behavioural status measurable, the BCI enables agencies to monitor progress beyond income and target support effectively, advancing the transition toward sustainable, equitable and resilient smallholder food systems.","实现消除贫困（可持续发展目标1）、通过可持续农业实现零饥饿（可持续发展目标2）以及减少不平等（可持续发展目标10），关键在于小农户的适应能力，而农民生产者组织（Farmer Producer Organisations, FPOs）被广泛推广以增强这一能力，然而对其评估一直集中于短期经济收益，忽视了支撑持续改善和韧性食物系统的行为转变，且可用于测量农户间此类行为差异的经过验证的多维工具十分有限。本研究开发了行为变化指数（Behavioural Change Index, BCI），并将其应用于印度奥里萨邦，以考察FPO成员身份与农户行为状况之间的关联。初始的142个题项经由80人专家组的关联性分析、信度检验、探索性因子分析、验证性因子分析、组合信度、平均方差抽取量、测量不变性、区分效度及共同方法偏差评估，在十二个有理论依据且经专家赋权的维度上精炼为89个题项，随后将该指数应用于300名FPO成员和100名非成员，并通过倾向得分匹配、逆概率加权、核匹配和全匹配、双重稳健估计及E值敏感性分析来处理选择偏差。BCI表现出极好的信度（Cronbach's α = 0.95）、清晰的十二因子结构（解释68.3%的方差）以及令人满意的区分效度；成员在所有十二个维度上的得分均显著更高（Cohen's d = 1.29–2.21），22.12分的原始优势在匹配后依然稳健（19.34分；双重稳健ATT = 19.71；E值 = 6.69），表明对未测量混杂因素的敏感性极低。因此，这项横断面研究既提供了一种心理测量学支持的测量工具，也提供了在调整可观测协变量后FPO成员与非成员之间行为状况差异的稳健观察证据。通过使行为状况可测量，BCI使各机构能够监测收入之外的进展并有效定向支持，从而推进小农户食物系统向可持续、公平和有韧性的方向转型。","2026-10-08T00:00:00Z",74,{"impact":17,"substance":261,"depth":19,"authority":117,"freshness":118,"relevant":21,"comment":262},22,"该研究开发了行为改变指数并验证其对印度小农组织成员行为差异的测量，方法严谨、数据扎实，对可持续小农食物系统评估有参考价值，但地域限于印度、影响层级偏学术细分领域。",[264],{"name":10,"url":255},[175,26,266,267,268],"印度农业","农民合作社","行为改变指数",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":272},{"candidates":273,"agricultural_evidence":46},[274,279,284],{"code":31,"score":275,"supported":46,"title":276,"abstract":277,"tags":278},16,[53],[175,53],[267,175],{"code":72,"score":20,"supported":46,"title":280,"abstract":281,"tags":283},[],[26,282],"sustainable agriculture",[26],{"code":285,"score":21,"supported":14,"title":286,"abstract":287,"tags":288},"J3",[],[],[266],[290,291],"行为改变指数 农民合作社 可持续农业 印度农业","行为改变指数 农民合作社","行为改变指数农民合作社可持续农业印度农业-4482","10.3389\u002Ffsufs.2026.1915367",{"doi":293,"openalex_id":295,"authors":296,"venue":10,"cited_by_count":95,"oa_url":255,"card":315,"direction":156,"ingested_from":102},"W7221022600",[297,299,301,304,307,309,311,313],{"name":298,"orcid":9},"Badigi Pavan Naik",{"name":300,"orcid":9},"Mahamaya Prasad Nayak",{"name":302,"orcid":303},"Bishnupriya Mishra","https:\u002F\u002Forcid.org\u002F0009-0007-6590-8967",{"name":305,"orcid":306},"Abhiram Dash","https:\u002F\u002Forcid.org\u002F0000-0002-6683-6594",{"name":308,"orcid":9},"Khitish Kumar Sarangi",{"name":310,"orcid":9},"Madhumita Jena",{"name":312,"orcid":9},"Indira Priyadarsini Pattnaik",{"name":314,"orcid":9},"Srabani Ghosal",{"tldr":316,"method":317,"finding":318,"direction":156,"opportunity":319},"构建并验证多维行为改变指数，评估印度农民生产者组织成员的行为差异。","专家赋权、因子分析、倾向得分匹配等，调查300名成员与100名非成员。","指数信效度良好，成员在12个维度均显著更高，匹配后优势仍稳健。","可将该行为指数嵌入数字平台，用于小农户行为监测与精准干预评估。","2026-10-09T23:30:06.254620Z",{"id":322,"title":323,"url":324,"summary":325,"summary_zh":326,"content":9,"source_name":327,"source_url":324,"published_at":328,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":329,"score_detail":330,"sources":333,"tags":335,"primary_topic":338,"secondary_topics":339,"classification":340,"search_phrases":356,"slug":359,"view_count":360,"doi":361,"paper":362,"created_at":374},3678,"An exploration of sustainable scaled-up operations for smallholder farms in China: drawing on international experience","https:\u002F\u002Fdoi.org\u002F10.1080\u002F23311932.2026.2736893","China’s persistent smallholder farming structure presents a major challenge for agricultural modernisation. This study adopts a farm management perspective, using smallholder farmers as the main micro-level analytical unit, to explore viable paths for achieving sustainable agricultural structural transformation in China. The core contradiction facing China’s agricultural development—the ‘Smallholder Dilemma’—is conceptualised as four interrelated structural constraints: insufficient cropland per household unit, fragmentation of land holdings leading to a significant increase in production costs, acceleration of land de-agriculture, and systematic failure of land mobility policies. International comparative analyses suggest that major advances in agricultural modernisation have often occurred alongside improvements in land governance, market institutions, agricultural service systems, and the organisation of production; however, the country cases do not establish a universal causal sequence or a directly transferable quantitative benchmark. Based on these findings, this study proposes a three-stage institutional framework tailored to China’s context. The framework emphasises improving land transfer and service-market mechanisms in the short term, establishing a rights-protective and voluntary push–pull mechanism to support agricultural transition in the medium term, and promoting diversified agricultural production entities and organisational innovation in the long term.","中国持续存在的小农经营结构对农业现代化构成重大挑战。本研究从农场管理视角出发，以小农作为主要微观分析单元，探讨中国实现可持续农业结构转型的可行路径。中国农业发展面临的核心矛盾——“小农困境”——被概念化为四个相互关联的结构性约束：户均耕地不足、土地细碎化导致生产成本显著上升、土地去农业化加速，以及土地流转政策的系统性失灵。国际比较分析表明，农业现代化的重大进展往往伴随着土地治理、市场制度、农业服务体系和生产组织的改善；然而，国别案例并不能确立普遍的因果顺序或可直接移植的量化基准。基于上述发现，本研究提出了一个针对中国情境的三阶段制度框架。该框架强调：短期内完善土地流转和服务市场机制；中期建立权利保障型和自愿性的推拉机制以支持农业转型；长期促进多元化农业生产主体和组织创新。","Cogent Food & Agriculture","2026-09-25T00:00:00Z",77,{"impact":19,"substance":115,"depth":116,"authority":117,"freshness":331,"relevant":21,"comment":332},8,"从农场管理视角系统剖析中国小农困境并提出三阶段制度框架，国际比较扎实，对农业现代化与土地政策研究有参考价值。",[334],{"name":327,"url":324},[175,27,125,336,337],"土地流转","土地治理",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":341},{"candidates":342,"agricultural_evidence":46},[343,348,352],{"code":31,"score":18,"supported":46,"title":344,"abstract":345,"tags":347},[53],[336,53,346],"land transfer",[125,336,175],{"code":44,"score":210,"supported":46,"title":349,"abstract":350,"tags":351},[],[27],[27],{"code":72,"score":66,"supported":46,"title":353,"abstract":354,"tags":355},[],[26],[],[357,358],"小农户 土地流转 农业现代化","小农困境 土地治理","小农户土地流转农业现代化-3678",2,"10.1080\u002F23311932.2026.2736893",{"doi":361,"openalex_id":363,"authors":364,"venue":327,"cited_by_count":95,"oa_url":368,"card":369,"direction":156,"ingested_from":102},"W7214366575",[365],{"name":366,"orcid":367},"Yujia Huo","https:\u002F\u002Forcid.org\u002F0009-0005-2578-2859","https:\u002F\u002Fwww.tandfonline.com\u002Fdoi\u002Fpdf\u002F10.1080\u002F23311932.2026.2736893?needAccess=true",{"tldr":370,"method":371,"finding":372,"direction":156,"opportunity":373},"基于农场管理视角，分析中国小农困境并借鉴国际经验提出三阶段制度框架。","国际比较分析与制度经济学框架，以小农为微观分析单元。","小农困境源于四重结构约束，需分短期、中期、长期三阶段制度创新。","可探究数字平台与土地流转、服务市场机制结合如何缓解小农困境。","2026-09-28T23:30:42.560643Z",{"id":376,"title":377,"url":378,"summary":379,"summary_zh":380,"content":9,"source_name":381,"source_url":378,"published_at":382,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":383,"score_detail":384,"sources":386,"tags":388,"primary_topic":393,"secondary_topics":394,"classification":395,"search_phrases":438,"slug":441,"view_count":360,"doi":442,"paper":443,"created_at":485},1400,"Bespoke Precision Agriculture for Small‐Scale Farming in Sub‐Saharan Africa: Defining Potential Benefits and Pathways","https:\u002F\u002Fdoi.org\u002F10.1002\u002Ffes3.70310","ABSTRACT Precision agriculture (PA) holds enormous potential for smallholder farmers in sub‐Saharan Africa (SSA), where agriculture remains central to economic development, employing more than half of the adult population and contributing significantly to GDP. However, adoption rates remain low. This communication examines the potential benefits, challenges and possible pathways for increasing uptake among smallholders in SSA. Drawing from recent initiatives and case studies, successful applications demonstrate that low‐cost, localised and gender inclusive PA innovations can increase adoption among smallholders. However, challenges such as high upfront technology costs, limited internet connectivity, low digital literacy, limited access to financial services and a lack of tailored training remain significant barriers. Addressing these barriers requires the co‐creation of affordable technologies and flexible financing schemes, the provision of support services, offline functionality and integrating PA into the educational curriculum and extension systems in SSA to build capacity to sustain adoption. Furthermore, promoting gender inclusivity and strengthening data management systems are equally important for long‐term success. By addressing these barriers, PA can drive sustainable agricultural production, improve food security and enhance climate resilience. This communication highlights the need for coordination among farmers, developers, researchers and policymakers to foster a robust PA ecosystem for smallholder farmers in SSA.","精准农业（PA）在撒哈拉以南非洲（SSA）的小农户中蕴藏着巨大潜力，该地区农业仍是经济发展的核心，雇佣了超过一半的成年人口，并对国内生产总值（GDP）贡献显著。然而，其采用率仍然较低。本文探讨了提高SSA小农户采用率的潜在益处、挑战及可行路径。借鉴近期举措和案例研究，成功应用表明，低成本、本地化且具有性别包容性的精准农业创新能够提高小农户的采用率。然而，高昂的前期技术成本、有限的互联网连接、较低的数字化素养、金融服务获取受限以及缺乏定制化培训等挑战，仍是重大障碍。应对这些障碍需要共同创造负担得起的技术和灵活的融资方案，提供支持服务、离线功能，并将精准农业纳入SSA的教育课程和推广体系，以建设维持采用的能力。此外，促进性别包容性和加强数据管理系统对长期成功同样重要。通过解决这些障碍，精准农业能够推动可持续农业生产、改善粮食安全并增强气候韧性。本文强调，农民、开发者、研究人员和政策制定者之间需要协调合作，以在SSA为小农户培育一个强大的精准农业生态系统。","Food and Energy Security","2026-09-01T00:00:00Z",76,{"impact":18,"substance":261,"depth":19,"authority":117,"freshness":66,"relevant":21,"comment":385},"论文探讨撒哈拉以南非洲小农精准农业的潜力与路径，对发展中国家智慧农业推广有参考价值。",[387],{"name":381,"url":378},[389,390,391,392,28],"智慧农业","精准农业","非洲农业","农业推广",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":396},{"candidates":397,"agricultural_evidence":46},[398,403,407,414,420,425,429,434],{"code":215,"score":275,"supported":46,"title":399,"abstract":401,"tags":402},[400],"precision agriculture",[390,400],[389,390],{"code":31,"score":20,"supported":46,"title":404,"abstract":405,"tags":406},[],[175,53],[28],{"code":408,"score":58,"supported":46,"title":409,"abstract":410,"tags":413},"A8",[],[411,412],"粮食安全","food security",[],{"code":415,"score":66,"supported":46,"title":416,"abstract":417,"tags":419},"H6",[],[418],"农业生态",[],{"code":65,"score":66,"supported":46,"title":421,"abstract":422,"tags":424},[],[423],"climate resilience",[],{"code":72,"score":66,"supported":46,"title":426,"abstract":427,"tags":428},[],[26],[],{"code":430,"score":21,"supported":14,"title":431,"abstract":432,"tags":433},"G1",[],[],[392],{"code":285,"score":21,"supported":14,"title":435,"abstract":436,"tags":437},[],[],[391],[439,440],"农业推广 小农经济 智慧农业 精准农业","农业推广 小农经济","农业推广小农经济智慧农业精准农业-1400","10.1002\u002Ffes3.70310",{"doi":442,"openalex_id":444,"authors":445,"venue":381,"cited_by_count":95,"oa_url":479,"card":480,"direction":250,"ingested_from":102},"W7204866587",[446,449,452,455,457,460,462,465,467,470,472,474,476],{"name":447,"orcid":448},"Kwame Agyei Frimpong","https:\u002F\u002Forcid.org\u002F0000-0002-2241-6985",{"name":450,"orcid":451},"Yaw Sarfo","https:\u002F\u002Forcid.org\u002F0000-0002-2538-4202",{"name":453,"orcid":454},"Isaac Asante","https:\u002F\u002Forcid.org\u002F0000-0003-2838-5275",{"name":456,"orcid":9},"Kwadwo A.

A classifier is modelled as a concept-rank operator whose singular values govern how much concept-level signal survives the projection from pixel space to class logits, and a collapse audit is defined as the ratio of retained concept-rank energy to total concept energy. Under a low-label regime, where concept annotations are scarce and the audit must be estimated from few labelled examples, the bound predicts that audit reliability degrades as a function of the concept-rank spectrum and the label budget. The analysis is a theoretical and methodological contribution: it derives the bound, states the conditions under which a collapse audit is identifiable, and characterises the operating characteristics of the audit as a decision procedure under a declared variance structure (between-cluster SD = 6.0, residual SD = 4.5, intraclass correlation = 0.64). Power was estimated across 2000 design cells for cluster counts of 8, 16, 24 and 32 and effect sizes of 3, 5 and 8 percentage points; 52 clusters were required for 5 percentage points at 80% power. The bound reframes concept audits as capacity tests rather than fidelity tests, with consequences for how smallholder fungicide-selectivity decisions should be supported by interpretable disease classifiers.","面向植物病害分类器的基于概念的可解释性方法，通常以其概念激活是否与人工标注标签相关作为评价标准，但该标准对一个更先前的问题保持沉默：分类器的内部表征是否保留了足够的概念秩结构，从而使任何审计具有信息量。本分析将该先前问题形式化为一个可解释性容量上界。分类器被建模为概念秩算子，其奇异值支配着从像素空间到类别logits的投影中概念级信号得以保留的程度，并将坍缩审计定义为保留的概念秩能量与总概念能量之比。在低标签情形下，概念标注稀缺且审计必须由少量标注样本估计，该上界预测审计可靠性会随概念秩谱和标签预算的函数而退化。本分析是一项理论和方法论贡献：推导出该上界，陈述坍缩审计可识别的条件，并在声明的方差结构（簇间SD = 6.0，残差SD = 4.5，组内相关系数 = 0.64）下刻画审计作为决策程序的操作特征。在2000个设计单元中，针对簇数为8、16、24和32以及效应量为3、5和8个百分点的情形估计了功效；在80%功效下达到5个百分点需要52个簇。该上界将概念审计重新框定为容量检验而非保真度检验，并对可解释病害分类器应如何支持小农杀菌剂选择性决策具有启示意义。","2026-10-21T00:00:00Z",{"impact":331,"substance":115,"depth":19,"authority":17,"freshness":13,"relevant":21,"comment":494},"理论方法论文，提出可解释性容量上界并给出审计功效分析，对智慧农业病害识别可信度有参考价值，但属小众方法学研究、缺乏田间实证，暂不宜进入每日精选。",[496],{"name":166,"url":489},[389,498,175,499,500],"农业人工智能","植物病害识别","可解释性",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[503],{"code":504,"slug":505,"name":506,"path":507,"parent_code":508},"I2","agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai","I",{"status":38,"locked":14,"version":39,"method":40,"evidence":510},{"candidates":511,"agricultural_evidence":46},[512,516,521],{"code":31,"score":17,"supported":46,"title":513,"abstract":514,"tags":515},[53],[53],[175],{"code":504,"score":13,"supported":46,"title":517,"abstract":519,"tags":520},[518],"computer vision",[],[498,499],{"code":215,"score":21,"supported":14,"title":522,"abstract":523,"tags":524},[],[],[389],[526,527],"农业人工智能 植物病害识别 可解释性 智慧农业","农业人工智能 植物病害识别","农业人工智能植物病害识别可解释性智慧农业-5592","10.5281\u002Fzenodo.23545193",{"doi":529,"openalex_id":531,"authors":532,"venue":166,"cited_by_count":95,"oa_url":489,"card":539,"direction":543,"ingested_from":102},"W7223137323",[533,535,537],{"name":534,"orcid":9},"Akshay Ramgoolam",{"name":536,"orcid":9},"Priya Bundhoo Appadoo",{"name":538,"orcid":9},"Jean-Noël LEspérance",{"tldr":540,"method":541,"finding":542,"direction":543,"opportunity":544},"提出可解释性容量上界，评估低标签下概念秩崩溃审计的可靠性。","将分类器建模为概念秩算子，推导容量上界并做2000格功效模拟。","审计可靠性随概念秩谱与标签预算下降；5个百分点效应需52个聚类达80%功效。","农业人工智能与决策模型","可将容量上界用于小农户杀菌剂选择性决策的可解释模型审计与标签预算设计。","2026-10-22T11:21:10.425290Z"]
