This study examined attitudes, adoption stages, socioeconomic correlates, information access and perceived constraints relating to RETs among arable crop farmers in Kwara State, Nigeria. Methods A multistage sampling procedure selected 180 farmers from four Local Government Areas. Data were collected using a structured questionnaire\u002Finterview schedule and analysed using descriptive statistics, Pearson correlation, fractional-logit regression and binary-logistic sensitivity analysis. Results After reverse-coding negatively worded items, the composite attitude score was 3.05 (SD = 0.45), while overall adoption remained low (grand mean = 1.11; adoption index = 0.22). Attitude was not significantly related to adoption extent ( r = 0.018, p = 0.806), and socioeconomic characteristics were not jointly associated with the fractional adoption index (Wald χ ( 12 ) 2 = 13.86, p = 0.310). In the sensitivity analysis, 49 farmers (27.2%) had reached the final adoption stage for at least one RET, and the binary-logistic model was significant overall (likelihood-ratio χ ( 5 ) 2 = 16.99, p = 0.0045). Farm size was positively associated with actual adoption, whereas years of education and farm income showed negative associations requiring cautious interpretation. High installation cost and limited access to credit were the leading constraints. Discussion RET adoption remained limited despite approximately neutral to slightly favourable attitudes. Since food-security outcomes were not directly measured, the findings indicate potential food-system implications rather than demonstrated effects on food security. Targeted financing, extension support and technical assistance may help address the identified adoption barriers.","引言 可再生能源技术（RETs）可支持农业能源需求，但小农户对其采用情况仍不均衡。本研究考察了尼日利亚夸拉州农作物种植农户对可再生能源技术的态度、采用阶段、社会经济相关因素、信息获取及感知制约因素。方法 采用多阶段抽样程序，从四个地方政府区域选取180名农户。通过结构化问卷\u002F访谈表收集数据，并运用描述性统计、皮尔逊相关、分数对数回归和二元逻辑敏感性分析进行分析。结果 对反向编码的负向表述条目进行反转后，综合态度得分为3.05（标准差=0.45），而总体采用水平仍然较低（总均值=1.11；采用指数=0.22）。态度与采用程度无显著相关（r=0.018，p=0.806），社会经济特征与分数采用指数亦无联合关联（Wald χ(12)²=13.86，p=0.310）。在敏感性分析中，49名农户（27.2%）至少对一种可再生能源技术达到了最终采用阶段，二元逻辑模型整体显著（似然比χ(5)²=16.99，p=0.0045）。农场规模与实际采用呈正相关，而受教育年限和农场收入呈负相关，需谨慎解读。高安装成本和信贷获取受限是主要制约因素。讨论 尽管态度总体呈中性至略偏积极，可再生能源技术的采用仍然有限。由于未直接测量粮食安全结果，研究结果表明潜在的食物系统影响，而非对粮食安全的实证效应。定向融资、推广支持和技术援助可能有助于解决已识别的采用障碍。",null,"Frontiers in Sustainable Food Systems","2026-08-31T00:00:00Z","论文",10,false,56,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},8,18,16,12,2,1,"研究尼日利亚小农采用可再生能源技术的态度与制约，数据详实，但地域局限且时效性低。",[25],{"name":10,"url":6},[27,28,29,30],"小农户","非洲农业","农业科技","可再生能源",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",[],{"status":39,"locked":14,"version":40,"method":41,"evidence":42},"classified","2026-10-22.2","rules",{"candidates":43,"agricultural_evidence":46},[44,51,59],{"code":32,"score":45,"supported":46,"title":47,"abstract":48,"tags":50},7,true,[],[27,49],"smallholder",[27],{"code":52,"score":53,"supported":46,"title":54,"abstract":55,"tags":58},"A8",6,[],[56,57],"粮食安全","food security",[],{"code":60,"score":22,"supported":14,"title":61,"abstract":62,"tags":63},"J3",[],[],[28],[65,66],"可再生能源 农业科技 非洲农业 小农户","可再生能源 农业科技","可再生能源农业科技非洲农业小农户-1286","10.3389\u002Ffsufs.2026.1895797",{"doi":68,"openalex_id":70,"authors":71,"venue":10,"cited_by_count":93,"oa_url":94,"card":95,"direction":99,"ingested_from":101},"W7204787684",[72,74,76,78,80,82,85,87,89,91],{"name":73,"orcid":9},"V.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).

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

= 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":20,"substance":113,"depth":311,"authority":312,"freshness":313,"relevant":22,"comment":314},17,13,9,"基于FAO

of Food Security Situation for Smallholder Farmers in Zvimba","https:\u002F\u002Fdoi.org\u002F10.71458\u002Frx0qpm30","This study provides a comprehensive analysis of the food security situation among smallholder farmers (SHFs) in Zvimba District, Zimbabwe. Smallholder agriculture is the bedrock of Zimbabwe's food system, yet it remains highly vulnerable to a complex array of shocks and stressors. Using a mixed-methods approach, this research investigates the prevalence, drivers and lived experiences of food insecurity within this community. A structured survey was administered to 412 randomly selected smallholder households across the district's wards. The quantitative data were supplemented by 12 Focus Group Discussions (FGDs) and 24 Key Informant Interviews (KIIs) with farmers, community leaders and agricultural extension officers to capture qualitative nuances. The study is grounded in the Food Security Theory (FST), which conceptualises food security through its four pillars: food availability, food access, food utilisation and food stability. Findings reveal a precarious food security situation. Quantitatively, 78.4% of households were found to be food insecure, with an average Hunger Months Index of 4.7 months per year. The study identifies a significant disconnect between maize production, the national staple and household consumption, with over 65% of households failing to produce enough maize to meet their annual requirements. Qualitative data illuminated the multi-faceted drivers of this insecurity. Key points to note include climate change whereby erratic rainfall and prolonged mid-season dry spells were consistently reported as the primary production challenges, limited access to farming inputs whereby high costs and unreliable supplies of certified seeds, fertilizers and agro[1]chemicals constrain productivity. Morelso, socio-economic factors such as poverty, lack of viable alternative livelihoods and limited access to formal credit perpetuate a cycle of vulnerability. In addition, institutional weaknesses, for example, challenges with agricultural extension services and market inefficiencies, exacerbate the situation. The study concludes that food insecurity in Zvimba is not merely a problem of food production, but is deeply rooted in structural issues affecting food access, food utilisation, as well as food stability. Recommendations are proposed for a multi-sectoral approach, including promoting Climate-Smart Agriculture (CSA) and drought-resistant crops, strengthening input support systems and rural finance, diversifying livelihood strategies and enhancing the capacity of extension services. This research contributes to a deeper understanding of the localised dynamics of food security and provides evidence-based guidance for policymakers, development practitioners and the farmers of Zvimba themselves.","本研究对津巴布韦兹维姆巴区小农户（smallholder farmers, SHFs）的粮食安全状况进行了全面分析。小农农业是津巴布韦粮食体系的基石，但仍极易受到一系列复杂冲击和压力的影响。本研究采用混合方法，考察了该社区粮食不安全的普遍程度、驱动因素及生活体验。研究对该区各选区随机抽取的412户小农户进行了结构化问卷调查。定量数据辅以12次焦点小组讨论（FGDs）和24次关键知情人访谈（KIIs），访谈对象包括农民、社区领袖和农业推广人员，以捕捉定性层面的细微差异。本研究以粮食安全理论（Food Security Theory, FST）为基础，该理论通过四大支柱界定粮食安全：粮食可供性、粮食获取、粮食利用和粮食稳定性。研究结果揭示了严峻的粮食安全形势。定量数据显示，78.4%的家庭存在粮食不安全，年均饥饿月份指数为4.7个月。研究发现，玉米产量——该国主粮——与家庭消费之间存在显著脱节，超过65%的家庭生产的玉米不足以满足其年度需求。定性数据揭示了这一不安全状况的多重驱动因素。值得注意的要点包括：气候变化，即降雨不稳定和持续的中期干旱被一致报告为主要生产挑战；农业投入品获取受限，即认证种子、化肥和农用化学品成本高昂且供应不可靠，制约了生产力。此外，贫困、缺乏可行的替代生计以及正规信贷获取受限等社会经济因素使脆弱性循环持续存在。此外，制度薄弱环节，例如农业推广服务面临的挑战和市场效率低下，加剧了这一状况。研究得出结论，兹维姆巴的粮食不安全不仅仅是粮食生产问题，而是深深植根于影响粮食获取、粮食利用以及粮食稳定性的结构性问题。研究提出了采取多部门方法的建议，包括推广气候智能型农业（Climate-Smart Agriculture, CSA）和抗旱作物、加强投入品支持体系和农村金融、多样化生计策略以及增强","Ngenani The Zimbabwe Ezekiel Guti Journal of Community Engagement and Societal Transformations","2026-10-20T00:00:00Z",55,{"impact":17,"substance":18,"depth":271,"authority":53,"freshness":17,"relevant":22,"comment":451},"基于412户调查与混合方法的扎实实证研究，但属津巴布韦地方性案例，公共影响与信源权威度有限，可作参考而非每日精选。",[453],{"name":447,"url":444},[56,27,455,456,457],"气候智慧农业","农业推广","津巴布韦",{"code":52,"slug":459,"name":460,"path":461,"parent_code":125},"yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security",[463,464],{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},{"code":352,"slug":465,"name":466,"path":467,"parent_code":133},"climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate",{"status":39,"locked":14,"version":40,"method":41,"evidence":469},{"candidates":470,"agricultural_evidence":46},[471,475,479,486,491,495,502],{"code":52,"score":271,"supported":46,"title":472,"abstract":473,"tags":474},[57],[56,57],[56],{"code":32,"score":271,"supported":46,"title":476,"abstract":477,"tags":478},[49],[27,49],[27],{"code":352,"score":13,"supported":46,"title":480,"abstract":481,"tags":485},[],[482,355,483,484],"气候变化","climate change","drought",[455],{"code":151,"score":45,"supported":46,"title":487,"abstract":488,"tags":490},[],[456,489],"agricultural extension",[456],{"code":121,"score":53,"supported":46,"title":492,"abstract":493,"tags":494},[],[123,122],[],{"code":496,"score":53,"supported":46,"title":497,"abstract":498,"tags":501},"G3",[],[499,500],"农村金融","rural finance",[],{"code":224,"score":163,"supported":46,"title":503,"abstract":504,"tags":506},[],[505],"smart agriculture",[],[508,509],"Zvimba 小农户 粮食安全","津巴布韦 小农 玉米","Zvimba小农户粮食安全-5478","10.71458\u002Frx0qpm30",{"doi":511,"openalex_id":513,"authors":514,"venue":447,"cited_by_count":93,"oa_url":9,"card":523,"direction":528,"ingested_from":101},"W7223029383",[515,518,521],{"name":516,"orcid":517},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":519,"orcid":520},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":522,"orcid":9},"Patience Mutopo",{"tldr":524,"method":525,"finding":526,"direction":99,"opportunity":527},"调查津巴布韦Zvimba小农户粮食安全状况，分析其普遍性、成因与实际体验。","混合方法：412户问卷、12场焦点小组、24个关键人物访谈，基于粮食安全四支柱理","78.4%家庭粮食不安全，年均饥饿月4.7个月，主因是气候、投入、社会经济与制度等结构性问题。","可探索用移动端问卷与遥感产量监测构建小农户粮食安全动态预警与精准干预系统。","智慧农业 \u002F 农业物联网","2026-10-21T23:30:08.937079Z"]
