Accurate maps of smallholder croplands thus hold great potential to inform a wide variety of policies including those that aim to address food insecurity, provide agricultural support, or encourage adaptation to climate change. However, many remotely sensed maps of croplands have been developed in ways that preferentially identify large, intensively managed fields. Here, we illustrate how remotely-sensed land cover maps could be improved to yield better information about smallholder farming, using Paraguay as a study system. We show that prior land cover maps dramatically underestimate smallholder croplands in Paraguay due to misclassification of these systems as a mixture of pastures, shrublands and forests. These maps fail to classify 55-99\\% of smallholder fields ($\u003C$ 5 ha) as croplands, overlooking more than 50 to 120 thousand farmers (or 16-43\\% of the farming population) in the country. We develop national-scale land cover maps that more accurately identify smallholder croplands, conducting a series of experiments to identify specific methodological practices that enable the greatest improvements in smallholder cropland mapping. We show that modest adjustments to the training sample can improve smallholder crop recall in Paraguay by more than 27 percentage points compared to the best performing existing crop map, while other modeling adjustments, such as field segmentation and 10 m pixel resolution, improve smallholder crop recall by an additional 8 percentage points. Our analysis underscores the need for remote sensing scientists to more carefully consider crop system heterogeneity and to ensure that all farming systems are represented in training data for crop mapping.","面积小于五公顷的农场产出了全球过半的农作物。因此，对小农农田的精确地图绘制对于制定多种政策具有巨大潜力，这些政策包括旨在解决粮食不安全问题、提供农业支持或鼓励适应气候变化的政策。然而，许多遥感绘制的农田地图在开发过程中倾向于识别大规模、集约化管理的田地。在此，我们以巴拉圭为研究区域，展示如何改进遥感土地覆盖图，以更好地提供关于小农农业的信息。我们发现，先前的地图由于将这些系统误分类为牧场、灌木丛和森林的混合体，严重低估了巴拉圭的小农农田。这些地图未能将55%至99%的小农田地（小于5公顷）识别为农田，从而忽视了该国超过5万至12万农民（占农业人口的16%至43%）。我们开发了全国范围的土地覆盖图，更准确地识别小农农田，并进行了一系列实验，以确定能够最大程度改进小农农田绘制的具体方法论实践。我们表明，与现有最佳农田地图相比，对训练样本进行适度调整可将巴拉圭小农作物的召回率提高超过27个百分点，而其他建模调整，如田块分割和10米像素分辨率，则进一步将小农作物的召回率提高8个百分点。我们的分析强调，遥感科学家需要更仔细地考虑作物系统的异质性，并确保所有农业系统在作物绘制的训练数据中都有代表性。",null,"Environmental

with farmers’ income using prefecture-level panel data from China spanning 2013 to 2024. We employ a two-way fixed-effects framework with standard errors clustered at the prefecture-level city, and measure regional agricultural technical efficiency using data envelopment analysis under variable returns to scale (DEA–VRS). The results show a significant positive association between family farm development and farmers' income, though the magnitude is modest. Instrumental variable estimates confirm the robustness of this association, with coefficients significantly larger than ordinary least squares results, revealing a pattern of negative selection in which family farms develop more rapidly in areas with weaker agricultural conditions. Mechanism tests indicate that agricultural technical efficiency serves as a partial mediator, while direct channels play the dominant role. Interaction-based heterogeneity analysis shows that the income-enhancing association is significantly stronger in western, non-major-grain-producing, and economically less-developed regions, consistent with diminishing marginal returns to organizational innovation. The findings provide empirical evidence for understanding the regional income effects of family farm development and inform the design of regionally differentiated policies.","本研究利用2013—2024年中国地级市面板数据，考察家庭农场发展与农民收入之间的关联。我们采用双向固定效应框架，并将标准误聚类到地级市层面，同时使用可变规模报酬下的数据包络分析（DEA–VRS）测度区域农业技术效率。结果表明，家庭农场发展与农民收入之间存在显著正相关，但幅度较为有限。工具变量估计证实了该关联的稳健性，且系数显著大于普通最小二乘结果，揭示出一种负向选择模式，即家庭农场在农业条件较弱的地区发展更快。机制检验表明，农业技术效率发挥部分中介作用，而直接渠道占主导地位。基于交互项的异质性分析显示，这种增收关联在西部、非粮食主产区和经济欠发达地区显著更强，这与组织创新的边际收益递减规律相一致。研究结论为理解家庭农场发展的区域收入效应提供了经验证据，并为区域差异化政策设计提供了参考。","Frontiers in Sustainable Food Systems","2026-09-09T00:00:00Z",78,{"impact":17,"substance":148,"depth":149,"authority":150,"freshness":151,"relevant":21,"comment":152},21,17,13,9,"基于2013—2024年地级面板数据与DEA-VRS、工具变量法的实证研究，结论扎实且具区域差异化政策含义，值得进入每日精选。",[154],{"name":144,"url":141},[156,157,27,158,159],"农民增收","家庭农场","区域差异","农业技术效率",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[],{"status":38,"locked":14,"version":39,"method":40,"evidence":163},{"candidates":164,"agricultural_evidence":45},[165,170],{"code":31,"score":166,"supported":45,"title":167,"abstract":168,"tags":169},4,[],[157],[157],{"code":171,"score":21,"supported":14,"title":172,"abstract":173,"tags":174},"G6",[],[],[156],[176,177],"农业技术效率 农业政策 农民增收 区域差异","农业技术效率 农业政策","农业技术效率农业政策农民增收区域差异-2035",5,"10.3389\u002Ffsufs.2026.1880985",{"doi":180,"openalex_id":182,"authors":183,"venue":144,"cited_by_count":83,"oa_url":141,"card":191,"direction":195,"ingested_from":90},"W7212082704",[184,187,189],{"name":185,"orcid":186},"Lin Fang","https:\u002F\u002Forcid.org\u002F0009-0001-1710-8144",{"name":188,"orcid":9},"Jingyu YIN",{"name":190,"orcid":9},"Zhou Fangzhou",{"tldr":192,"method":193,"finding":194,"direction":195,"opportunity":196},"基于中国地级市面板数据，检验家庭农场发展对农民收入的关联及农业技术效率的中介作用。","2013-2024年地级市面板数据，双向固定效应、DEA-VRS测效率、工具变量","家庭农场发展与农民收入显著正相关但幅度有限，技术效率仅部分中介，直接渠道主导，西部和欠发达地区效应更","数字乡村与农业信息化","可探究数字技术\u002F信息化服务如何增强家庭农场对农民收入的直接渠道，并关注欠发达地区的异质性机制。","2026-09-10T23:30:07.795645Z",{"id":199,"title":200,"url":201,"summary":202,"summary_zh":203,"content":9,"source_name":204,"source_url":201,"published_at":205,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":206,"score_detail":207,"sources":209,"tags":211,"primary_topic":216,"secondary_topics":217,"classification":224,"search_phrases":241,"slug":244,"view_count":83,"doi":245,"paper":246,"created_at":261},5592,"Evaluation of Concept-Rank Collapse Audits for Computer Vision Agriculture Disease Classifiers Under Low-Label Regimes: An Interpretability Capacity Bound for Smallholder Fungicide Selectivity","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23545193","Concept-based interpretability methods for plant-disease classifiers are typically evaluated by whether their concept activations correlate with human-annotated labels, but this criterion is silent on a prior question: whether the classifier's internal representation retains enough concept-rank structure for any audit to be informative. the present analysis formalises that prior question as an interpretability capacity bound. 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。","Zenodo (CERN European Organization for Nuclear Research)","2026-10-21T00:00:00Z",69,{"impact":108,"substance":148,"depth":17,"authority":19,"freshness":13,"relevant":21,"comment":208},"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。",[210],{"name":204,"url":201},[212,213,123,214,215],"智慧农业","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},[218],{"code":219,"slug":220,"name":221,"path":222,"parent_code":223},"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":225},{"candidates":226,"agricultural_evidence":45},[227,231,236],{"code":31,"score":19,"supported":45,"title":228,"abstract":229,"tags":230},[47],[47],[123],{"code":219,"score":13,"supported":45,"title":232,"abstract":234,"tags":235},[233],"computer vision",[],[213,214],{"code":237,"score":21,"supported":14,"title":238,"abstract":239,"tags":240},"I1",[],[],[212],[242,243],"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":245,"openalex_id":247,"authors":248,"venue":204,"cited_by_count":83,"oa_url":201,"card":255,"direction":259,"ingested_from":90},"W7223137323",[249,251,253],{"name":250,"orcid":9},"Akshay Ramgoolam",{"name":252,"orcid":9},"Priya Bundhoo Appadoo",{"name":254,"orcid":9},"Jean-Noël LEspérance",{"tldr":256,"method":257,"finding":258,"direction":259,"opportunity":260},"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",{"id":263,"title":264,"url":265,"summary":266,"summary_zh":267,"content":9,"source_name":204,"source_url":265,"published_at":205,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":268,"score_detail":269,"sources":271,"tags":273,"primary_topic":276,"secondary_topics":277,"classification":279,"search_phrases":294,"slug":297,"view_count":83,"doi":298,"paper":299,"created_at":313},5590,"Evaluation of Concept-Probe Temporal-Stability Audits for Computer Vision Agriculture Disease Classifiers Under Seasonal Phenology Drift: An Interpretability Decay Bound for Smallholder Fungicide Timing","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.23545234","Concept-probe audits are increasingly used to certify that a crop-disease classifier's internal representations track the pathological concepts a smallholder would act on, but a probe certified at one point in the season may silently decouple from those concepts as phenology shifts the visual statistics of the field. the present analysis treats that decoupling as a formal object. It defines a temporal-stability audit as a sequence of concept-probe accuracies measured across defined phenological windows, and it derives an interpretability decay bound: the rate at which probe accuracy can fall before the fungicide-timing decision it is meant to support becomes unreliable. The bound is expressed as a function of the probe's initial margin, the drift in concept prevalence between windows, and the classifier's sensitivity to the drifted features, and it yields a certified audit interval rather than a single-point certificate. The paper then characterises the operating characteristics of the audit design under a declared variance structure, using a replication-based evaluation of the before-after-control-impact estimator with between-cluster SD = 6.0, residual SD = 4.5 and intraclass correlation = 0.64.

Agroecology offers a promising pathway to enhance resilience and support inclusive rural development. In this context, Tunisia’s olive sector provides a relevant case for examining agroecological transitions in semi-arid smallholder systems. This study evaluates the degree of agroecological transition among smallholder olive farms in the Elles region of northwestern Tunisia using the FAO Tool for Agroecology Performance Evaluation (TAPE). Based on a sample of 60 farms, the analysis applies the Characterization of Agroecological Transition (CAET) index, grounded in the 10 Elements of Agroecology, to compare four production systems: (i) olive monoculture, (ii) diversified cropping, (iii) olive–livestock integration, and (iv) integrated olive–crop–livestock systems. Economic, social, environmental and institutional performance were explored using the TAPE Core Criteria of Performance (Step 2) and examined in relation to CAET scores. Results reveal a clear agroecological gradient, with diversified and integrated systems achieving markedly higher CAET scores (up to 52%) compared to monoculture systems (31%). Spearman correlations show strong associations between CAET and key dimensions, including synergy (ρ = 0.79), human and social values (ρ = 0.78), and diversity (ρ = 0.71). Several TAPE economic performance indicators, including monthly income, which ranged from approximately 1,349 TND in monoculture systems to 4,892 TND in diversified olive–crop–livestock systems, were positively associated with higher CAET scores, suggesting that agroecological transition may not necessarily imply a trade-off between productivity and sustainability. However, limited collective action, weak market integration, and insufficient extension services constrain broader adoption. These findings highlight the potential of diversification as a key lever for agroecological transition and underscore the importance of targeted policy support.","农业集约化提高了产量并促进了经济增长，但也产生了威胁长期可持续性的重大环境与社会挑战，凸显了对更可持续耕作模式的需求。农业生态学为增强韧性和支持包容性农村发展提供了一条有前景的路径。在此背景下，突尼斯橄榄产业为研究半干旱小农系统中的农业生态转型提供了相关案例。本研究利用联合国粮农组织农业生态性能评价工具（TAPE），评估突尼斯西北部埃勒斯地区小农橄榄农场的农业生态转型程度。基于60个农场的样本，分析采用以农业生态学十大要素为基础的农业生态转型特征（CAET）指数，比较四种生产系统：（i）橄榄单作，（ii）多样化种植，（iii）橄榄—畜牧结合，以及（iv）橄榄—作物—畜牧综合系统。研究利用TAPE核心性能标准（第二步）探讨经济、社会、环境和制度绩效，并将其与CAET得分进行关联分析。结果揭示了明显的农业生态梯度，多样化与综合系统的CAET得分（最高达52%）显著高于单作系统（31%）。斯皮尔曼相关性分析显示，CAET与关键维度之间存在强关联，包括协同性（ρ = 0.79）、人文与社会价值（ρ = 0.78）和多样性（ρ = 0.71）。若干TAPE经济绩效指标——包括月收入，其从单作系统的约1，349突尼斯第纳尔到橄榄—作物—畜牧多样化系统的4，892突尼斯第纳尔不等——与更高的CAET得分呈正相关，表明农业生态转型未必意味着生产力与可持续性之间的权衡。然而，集体行动有限、市场整合薄弱和推广服务不足制约了更广泛的采纳。这些发现凸显了多样化作为农业生态转型关键杠杆的潜力，并强调了有针对性的政策支持的重要性。",71,{"impact":19,"substance":322,"depth":149,"authority":150,"freshness":151,"relevant":21,"comment":323},20,"基于FAO
