Among the most widely grown vegetables are cruciferous crops, while traditional African vegetables have increasingly gained prominence in recent years. Smallholder farmers account for more than 70% of the country’s total vegetable production. However, they face various complex factors such as extreme climate variability, invertebrate pests, and diseases which reduce productivity, yields and household incomes. They, therefore, often resort to the overuse of synthetic fertilizers and pesticides that could increase their susceptibility to pest resistance, declining soil fertility, and production risks. Agroecological cropping systems have been shown to improve soil fertility, suppress pests, and support sustainable livelihoods in Kenya. Nevertheless, despite their potential benefits, the adoption of agroecological cropping systems remains low. Therefore, this study aims to empirically analyze the factors influencing smallholder farmers’ adoption of selected agroecological vegetable cropping systems in Kenya. This study utilized a multistage sampling approach to gather cross-sectional data from 546 farmers cultivating cruciferous and traditional African vegetables in Kiambu and Murang’a counties. The sample size was determined using the specified sampling methodology. The agroecological vegetable cropping systems examined in this study included mixed cropping, strip cropping, row intercropping, border cropping, and crop rotation. Data was analyzed using a multivariate probit regression model. The findings indicated that adoption decisions were multivariate and interdependent across agroecological cropping systems. Household head gender, plot manager gender, and access to extension services had varying positive and negative impacts on the adoption of agroecological cropping systems. In addition, the occupation of the household head and income from non-vegetable farming activities was positively associated with adoption, while gross income derived from vegetable production was negatively associated with the adoption of some cropping systems. These findings highlight the need to strengthen agricultural extension services, promote gender-responsive farmer training, improve access to market opportunities, and support income diversification initiatives to enhance the adoption of agroecological vegetable cropping systems among smallholder farmers.","蔬菜生产在肯尼亚改善营养和增加收入方面发挥着重要作用，是该国农业部门的重要组成部分。在种植最广泛的蔬菜中，十字花科作物占据重要地位，而传统非洲蔬菜近年来日益受到重视。小农户占该国蔬菜总产量的70%以上。然而，他们面临着极端气候变率、无脊椎动物害虫和病害等各种复杂因素，这些因素降低了生产力、产量和家庭收入。因此，他们往往过度使用合成肥料和农药，这可能增加其对害虫抗药性、土壤肥力下降和生产风险的脆弱性。农业生态种植系统已被证明能够改善土壤肥力、抑制害虫，并支持肯尼亚的可持续生计。然而，尽管具有潜在效益，农业生态种植系统的采用率仍然较低。因此，本研究旨在实证分析影响肯尼亚小农户采用特定农业生态蔬菜种植系统的因素。本研究采用多阶段抽样方法，从基安布郡和穆兰阿郡种植十字花科蔬菜和传统非洲蔬菜的546名农户中收集横截面数据。样本量根据指定的抽样方法确定。本研究考察的农业生态蔬菜种植系统包括混作、条带种植、行间套作、边行种植和轮作。数据采用多元概率比回归模型进行分析。研究结果表明，各农业生态种植系统的采用决策具有多元性和相互依赖性。户主性别、地块管理者性别以及推广服务的获取对农业生态种植系统的采用产生了不同的正向和负向影响。此外，户主的职业和非蔬菜种植活动的收入与采用呈正相关，而蔬菜生产的总收入与某些种植系统的采用呈负相关。这些发现强调了加强农业推广服务、促进性别响应的农户培训、改善市场机会获取以及支持收入多样化举措的必要性，以促进农业生态蔬菜种植系统的采用。",null,"Frontiers in Sustainable Food Systems","2026-09-03T00:00:00Z","论文",10,false,60,{"impact":17,"substance":18,"depth":19,"authority":17,"freshness":20,"relevant":21,"comment":22},12,18,16,2,1,"研究东非小农采纳生态农业种植系统的影响因素，数据详实，对农业推广有参考价值，但时效性较低。",[24],{"name":10,"url":6},[26,27,28,29],"非洲","小农户","农业生态","蔬菜种植",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},"B1","vegetables","蔬菜","\u002Ftopic\u002Fhorticulture\u002Fvegetables","B",[37,43],{"code":38,"slug":39,"name":40,"path":41,"parent_code":42},"A7","forage-cropping","饲草与耕作制度","\u002Ftopic\u002Ffield-crops\u002Fforage-cropping","A",{"code":44,"slug":45,"name":46,"path":47,"parent_code":48},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",{"status":50,"locked":14,"version":51,"method":52,"evidence":53},"classified","2026-10-22.2","rules",{"candidates":54,"agricultural_evidence":57},[55,62,67,75,83,90,96,103],{"code":31,"score":56,"supported":57,"title":58,"abstract":60,"tags":61},15,true,[59],"vegetable",[33,59],[29],{"code":44,"score":56,"supported":57,"title":63,"abstract":65,"tags":66},[64],"smallholder",[27,64],[27],{"code":38,"score":68,"supported":57,"title":69,"abstract":70,"tags":74},9,[],[71,72,73],"轮作","crop rotation","intercropping",[],{"code":76,"score":77,"supported":57,"title":78,"abstract":79,"tags":82},"G1",6,[],[80,81],"农业推广","agricultural extension",[],{"code":84,"score":77,"supported":57,"title":85,"abstract":86,"tags":89},"H2",[],[87,88],"土壤","soil",[],{"code":91,"score":92,"supported":57,"title":93,"abstract":94,"tags":95},"H6",4,[],[28],[28],{"code":97,"score":98,"supported":57,"title":99,"abstract":100,"tags":102},"F3",3,[],[101],"肥料",[],{"code":104,"score":98,"supported":57,"title":105,"abstract":106,"tags":108},"F4",[],[107],"农药",[],[110,111],"农业生态 蔬菜种植 小农户 非洲","农业生态 蔬菜种植","农业生态蔬菜种植小农户非洲-1519","10.3389\u002Ffsufs.2026.1899227",{"doi":113,"openalex_id":115,"authors":116,"venue":10,"cited_by_count":128,"oa_url":6,"card":129,"direction":133,"ingested_from":135},"W7206195758",[117,120,122,124,126],{"name":118,"orcid":119},"Essy C.

This study assessed the contribution of climate adaptation practices to tomato productivity among 150 smallholder farmers in Lusaka West, Zambia, using a convergent mixed-methods design. Quantitative data were analysed using descriptive statistics and Pearson correlation, while qualitative data were analysed thematically. Most farmers (88%) reported experiencing climate variability, mainly through irregular rainfall, drought, and rising temperatures. Adaptation strategies were widely adopted (86%), with irrigation and improved seed varieties being the most common. About 76% of respondents reported improved tomato yields and 72% reported increased household income following adaptation. A strong positive relationship was observed between adaptation strategies and tomato yields (r = 0.718, p \u003C 0.001), indicating that increased adoption of adaptation practices significantly enhanced production performance. Qualitative findings confirmed that adaptation improved resilience but highlighted financial constraints, limited irrigation infrastructure, and inadequate climate information as major barriers. The study concludes that climate adaptation strategies strengthen the resilience and productivity of smallholder tomato farming systems. Strengthening extension services, expanding access to affordable irrigation technologies, and promoting climate-smart agriculture are essential for enhancing sustainable horticultural production and food security in Zambia.","气候变异性对撒哈拉以南非洲小农户的番茄生产构成日益严重的威胁，然而关于农场层面适应策略有效性的证据仍然有限。本研究采用收敛混合方法设计，评估了气候适应实践对赞比亚卢萨卡西部150名小农户番茄生产力的贡献。定量数据采用描述性统计和皮尔逊相关分析，定性数据则采用主题分析法进行处理。大多数农户（88%）报告经历了气候变异性，主要表现为降雨不规律、干旱和气温上升。适应策略被广泛采用（86%），其中灌溉和改良种子品种最为常见。约76%的受访者报告番茄产量提高，72%的受访者报告适应后家庭收入增加。适应策略与番茄产量之间呈显著正相关关系（r = 0.718，p \u003C 0.001），表明适应实践采用程度的提高显著增强了生产绩效。定性研究结果证实，适应措施增强了韧性，但也凸显了资金约束、灌溉基础设施有限以及气候信息不足等主要障碍。研究得出结论：气候适应策略能够增强小农户番茄种植系统的韧性和生产力。加强推广服务、扩大经济适用灌溉技术的获取渠道以及推广气候智能型农业，对于提升赞比亚可持续园艺生产和粮食安全至关重要。","International Journal of Innovative Science and Research Technology (IJISRT)","2026-09-04T00:00:00Z",56,{"impact":17,"substance":18,"depth":19,"authority":149,"freshness":20,"relevant":21,"comment":150},8,"针对赞比亚小农番茄生产的气候适应研究，数据详实，但地域局限且时效性低，作为国际案例有一定参考价值。",[152],{"name":145,"url":142},[154,27,155,156],"智慧农业","气候变化适应","番茄生产",{"code":31,"slug":32,"name":33,"path":34,"parent_code":35},[159,165],{"code":160,"slug":161,"name":162,"path":163,"parent_code":164},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"code":44,"slug":45,"name":46,"path":47,"parent_code":48},{"status":50,"locked":14,"version":51,"method":52,"evidence":167},{"candidates":168,"agricultural_evidence":57},[169,177,181,188,195,202],{"code":160,"score":18,"supported":57,"title":170,"abstract":172,"tags":176},[171],"climate resilience",[173,174,175],"气候适应","干旱","drought",[155],{"code":44,"score":56,"supported":57,"title":178,"abstract":179,"tags":180},[64],[27,64],[27],{"code":31,"score":182,"supported":57,"title":183,"abstract":185,"tags":187},14,[184],"tomato",[186,184],"番茄",[],{"code":189,"score":77,"supported":57,"title":190,"abstract":191,"tags":194},"A8",[],[192,193],"粮食安全","food security",[],{"code":196,"score":77,"supported":57,"title":197,"abstract":198,"tags":201},"H3",[],[199,200],"灌溉","irrigation",[],{"code":203,"score":92,"supported":57,"title":204,"abstract":205,"tags":207},"I1",[],[206],"smart agriculture",[154],[209,210],"气候变化适应 智慧农业 番茄生产 小农户","气候变化适应 智慧农业","气候变化适应智慧农业番茄生产小农户-1726","10.38124\u002Fijisrt\u002F26aug501",{"doi":212,"openalex_id":214,"authors":215,"venue":145,"cited_by_count":128,"oa_url":142,"card":220,"direction":226,"ingested_from":135},"W7208767895",[216,218],{"name":217,"orcid":9},"Evaristo Nyeleti",{"name":219,"orcid":9},"Joseph T.

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).

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.

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":17,"substance":488,"depth":489,"authority":240,"freshness":68,"relevant":21,"comment":490},20,17,"基于FAO TAPE方法对突尼斯小农户橄榄系统农生态转型的实证研究，数据扎实、结论有新意，但属区域性案例，公共影响有限。",[492],{"name":10,"url":483},[27,494,495,496,497],"农业转型","生态农业","突尼斯","油橄榄",{"code":44,"slug":45,"name":46,"path":47,"parent_code":48},[],{"status":50,"locked":14,"version":51,"method":52,"evidence":501},{"candidates":502,"agricultural_evidence":57},[503,507,514,520,525,529],{"code":44,"score":17,"supported":57,"title":504,"abstract":505,"tags":506},[64],[64],[27],{"code":508,"score":77,"supported":57,"title":509,"abstract":510,"tags":513},"C",[],[511,512],"畜牧","livestock",[],{"code":48,"score":77,"supported":57,"title":515,"abstract":516,"tags":519},[],[517,518],"农村发展","rural development",[],{"code":91,"score":77,"supported":57,"title":521,"abstract":522,"tags":524},[],[28,523],"agroecology",[],{"code":160,"score":98,"supported":57,"title":526,"abstract":527,"tags":528},[],[174],[],{"code":530,"score":21,"supported":14,"title":531,"abstract":532,"tags":533},"H8",[],[],[495],[535,536],"突尼斯 油橄榄 小农户","TAPE 农生态 评估","突尼斯油橄榄小农户-5548","10.3389\u002Ffsufs.2026.1903591",{"doi":538,"openalex_id":540,"authors":541,"venue":10,"cited_by_count":128,"oa_url":483,"card":562,"direction":224,"ingested_from":135},"W7223108121",[542,544,546,549,552,554,557,560],{"name":543,"orcid":9},"Rihab Mejri",{"name":545,"orcid":9},"Meriem Oueslati Zlaoui",{"name":547,"orcid":548},"Inès Gharbi","https:\u002F\u002Forcid.org\u002F0000-0003-2558-2134",{"name":550,"orcid":551},"Asma Souissi","https:\u002F\u002Forcid.org\u002F0000-0002-8680-5875",{"name":553,"orcid":9},"Ghada Ferchichi",{"name":555,"orcid":556},"Rania Soula","https:\u002F\u002Forcid.org\u002F0000-0002-6086-9176",{"name":558,"orcid":559},"Boubaker Dhehibi","https:\u002F\u002Forcid.org\u002F0000-0003-3854-6669",{"name":561,"orcid":9},"Mohamed Zied Dhraief",{"tldr":563,"method":564,"finding":565,"direction":224,"opportunity":566},"用FAO TAPE工具评估突尼斯西北小农橄榄农场生态农业转型程度。","FAO TAPE框架与CAET指数，调查60个农场比较四类种植系统。","多样化与综合系统CAET得分达52%，单作仅31%，且收入更高。","可将TAPE与CAET指标数字化，构建小农生态转型监测与决策支持系统。","2026-10-22T11:20:15.716064Z"]
