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。",null,"Food and Energy Security","2026-09-01T00:00:00Z","论文",10,false,76,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},20,22,18,13,3,1,"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。",[25],{"name":10,"url":6},[27,28,29,30,31],"智慧农业","精准农业","非洲农业","农业推广","小农经济",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":48},[45,53,60,68,74,80,86,91],{"code":46,"score":47,"supported":48,"title":49,"abstract":51,"tags":52},"I1",16,true,[50],"precision agriculture",[28,50],[27,28],{"code":33,"score":54,"supported":48,"title":55,"abstract":56,"tags":59},7,[],[57,58],"小农户","smallholder",[31],{"code":61,"score":62,"supported":48,"title":63,"abstract":64,"tags":67},"A8",6,[],[65,66],"粮食安全","food security",[],{"code":69,"score":21,"supported":48,"title":70,"abstract":71,"tags":73},"H6",[],[72],"农业生态",[],{"code":75,"score":21,"supported":48,"title":76,"abstract":77,"tags":79},"H7",[],[78],"climate resilience",[],{"code":81,"score":21,"supported":48,"title":82,"abstract":83,"tags":85},"H8",[],[84],"可持续农业",[],{"code":87,"score":22,"supported":14,"title":88,"abstract":89,"tags":90},"G1",[],[],[30],{"code":92,"score":22,"supported":14,"title":93,"abstract":94,"tags":95},"J3",[],[],[29],[97,98],"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",2,"10.1002\u002Ffes3.70310",{"doi":101,"openalex_id":103,"authors":104,"venue":10,"cited_by_count":138,"oa_url":139,"card":140,"direction":146,"ingested_from":147},"W7204866587",[105,108,111,114,116,119,121,124,126,129,131,133,135],{"name":106,"orcid":107},"Kwame Agyei Frimpong","https:\u002F\u002Forcid.org\u002F0000-0002-2241-6985",{"name":109,"orcid":110},"Yaw Sarfo","https:\u002F\u002Forcid.org\u002F0000-0002-2538-4202",{"name":112,"orcid":113},"Isaac Asante","https:\u002F\u002Forcid.org\u002F0000-0003-2838-5275",{"name":115,"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.

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.

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":161,"substance":19,"depth":288,"authority":62,"freshness":161,"relevant":22,"comment":330},"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。",[332],{"name":326,"url":323},[65,57,334,30,335],"气候智慧农业","津巴布韦",{"code":61,"slug":337,"name":338,"path":339,"parent_code":340},"yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[342,343],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"code":75,"slug":344,"name":345,"path":346,"parent_code":347},"climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":40,"locked":14,"version":41,"method":42,"evidence":349},{"candidates":350,"agricultural_evidence":48},[351,355,359,367,372,379,386],{"code":61,"score":288,"supported":48,"title":352,"abstract":353,"tags":354},[66],[65,66],[65],{"code":33,"score":288,"supported":48,"title":356,"abstract":357,"tags":358},[58],[57,58],[57],{"code":75,"score":13,"supported":48,"title":360,"abstract":361,"tags":366},[],[362,363,364,365],"气候变化","干旱","climate change","drought",[334],{"code":87,"score":54,"supported":48,"title":368,"abstract":369,"tags":371},[],[30,370],"agricultural extension",[30],{"code":373,"score":62,"supported":48,"title":374,"abstract":375,"tags":378},"A3",[],[376,377],"玉米","maize",[],{"code":380,"score":62,"supported":48,"title":381,"abstract":382,"tags":385},"G3",[],[383,384],"农村金融","rural finance",[],{"code":46,"score":21,"supported":48,"title":387,"abstract":388,"tags":390},[],[389],"smart agriculture",[],[392,393],"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":395,"openalex_id":397,"authors":398,"venue":326,"cited_by_count":138,"oa_url":9,"card":407,"direction":146,"ingested_from":147},"W7223029383",[399,402,405],{"name":400,"orcid":401},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":403,"orcid":404},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":406,"orcid":9},"Patience Mutopo",{"tldr":408,"method":409,"finding":410,"direction":144,"opportunity":411},"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。","2026-10-21T23:30:08.937079Z",{"id":414,"title":415,"url":416,"summary":417,"summary_zh":418,"content":9,"source_name":419,"source_url":416,"published_at":420,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":421,"score_detail":422,"sources":426,"tags":428,"primary_topic":433,"secondary_topics":434,"classification":435,"search_phrases":447,"slug":450,"view_count":138,"doi":451,"paper":452,"created_at":467},4815,"Sustainability of smallholder farming in large-scale mining enclaves in Ghana: the case of Asutifi North District in the Ahafo region, Ghana","https:\u002F\u002Fdoi.org\u002F10.1080\u002F19376812.2026.2692026","This paper argues that Ghana’s land and mineral extraction laws favor large-scale mining against agricultural livelihoods. As a result, the paper examined how large-scale land acquisition affects agrarian land availability, productivity, and sustainability of smallholder farming. Using a case study design, the study employed multiple qualitative methods including focus group discussions, document review, and interviews of officials of relevant institutions and project-affected persons (PAPs). PAPs, key informants and institutions were purposively sampled for interviews. Results show that current land regulations only provide one-time compensation for displaced farmers. This approach fails to consider the long-term needs of affected farming households. The findings further indicate that PAPs often share their compensation with extended family members as part of a cultural obligation. While this practice demonstrates community support, it leaves displaced households with little to nothing left for their own basic needs and long-term sustenance. The paper proposed modern smart agriculture that thrives on smaller lands and the development of a sustainable compensation framework that considers the long-term impacts of land acquisition will help manage land management conflicts and the sustainability of agriculture in mining communities.","本文认为，加纳的土地与矿产开采法律偏向大规模采矿，不利于农业生计。因此，本文考察了大规模土地征用如何影响农户的土地可获得性、生产力及小农农业的可持续性。研究采用案例研究设计，运用多种定性方法，包括焦点小组讨论、文献查阅以及对相关机构官员和受项目影响者（PAPs）的访谈。受项目影响者、关键信息提供者和相关机构均通过目的性抽样选取进行访谈。结果表明，现行土地法规仅对被征地农民提供一次性补偿。这种做法未能考虑受影响农户的长期需求。研究结果进一步显示，受项目影响者往往将补偿金与大家庭成员分享，这被视为一种文化义务。尽管这种做法体现了社区互助，却使被征地农户几乎无余力满足自身基本需求和长期生计。本文提出，发展依托较小土地的现代智慧农业，并建立考虑土地征用长期影响的可持续补偿框架，将有助于管理土地管理冲突以及矿区农业的可持续性。","African Geographical Review","2026-10-11T00:00:00Z",67,{"impact":161,"substance":17,"depth":423,"authority":20,"freshness":424,"relevant":22,"comment":425},17,9,"加纳采矿飞地小农可持续性案例研究，揭示一次性补偿缺陷并提出智慧农业与长效补偿框架，对矿区农业治理有参考价值。",[427],{"name":419,"url":416},[27,429,430,431,432],"小农生计","土地征收","采矿冲突","补偿机制",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":436},{"candidates":437,"agricultural_evidence":48},[438,443],{"code":33,"score":439,"supported":48,"title":440,"abstract":441,"tags":442},11,[58],[58],[],{"code":46,"score":54,"supported":48,"title":444,"abstract":445,"tags":446},[],[27,389],[27],[448,449],"加纳 Asutifi North 小农","大型采矿 土地征收 补偿","加纳AsutifiNorth小农-4815","10.1080\u002F19376812.2026.2692026",{"doi":451,"openalex_id":453,"authors":454,"venue":419,"cited_by_count":138,"oa_url":9,"card":462,"direction":146,"ingested_from":147},"W7221569207",[455,457,460],{"name":456,"orcid":9},"Natalia Poku-Boansi",{"name":458,"orcid":459},"Clifford Amoako","https:\u002F\u002Forcid.org\u002F0000-0001-9751-3037",{"name":461,"orcid":9},"John Tiah Bugri",{"tldr":463,"method":464,"finding":465,"direction":144,"opportunity":466},"研究加纳大型采矿征地对小农农业可持续性的影响，并提出智慧农业与补偿框架建议。","案例研究，采用焦点小组、文献审查和访谈等定性方法。","一次性补偿忽视长期需求，且补偿被分享后农户难以维持生计。","可探索在采矿影响区推广小地块智慧农业技术，并设计长期补偿与生计恢复机制。","2026-10-13T23:30:12.118168Z",{"id":469,"title":470,"url":471,"summary":472,"summary_zh":473,"content":9,"source_name":474,"source_url":471,"published_at":475,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":476,"score_detail":477,"sources":479,"tags":481,"primary_topic":485,"secondary_topics":486,"classification":487,"search_phrases":508,"slug":511,"view_count":138,"doi":512,"paper":513,"created_at":524},4601,"Digital Agriculture and Sector Transformation in South Africa","https:\u002F\u002Fdoi.org\u002F10.36096\u002Fijbes.v8i4.1274","Digitalisation is increasingly promoted as a catalyst for agricultural productivity, climate resilience, and market integration. However, there is limited systematic analysis of how digital agricultural transformation unfolds within South Africa’s institutional and socio-economic context. This study examines the trajectory, drivers, and governance implications of digitalisation in South African agriculture. Anchored in an integrated Socio-Technical Systems and Digital Agriculture Ecosystem framework, the study applies a structured qualitative document analysis of 82 academic and policy documents published between 2013 and 2025. The findings reveal highly uneven digital adoption patterns that reflect a structural dualism between capital-intensive commercial agriculture and resource-constrained smallholder systems. While South Africa has developed a relatively advanced digital policy architecture, implementation fragmentation, infrastructure constraints, and limited capacity for extension impede inclusive digital outcomes. The study contributes by integrating socio-technical and ecosystem perspectives to analyse digital transitions in emerging economies and by providing a transparent analytical protocol for document-based research. Policy implications highlight the need for coordinated governance, investment in rural connectivity, and targeted support mechanisms to ensure equitable digital transformation.","数字化日益被视为提升农业生产力、增强气候韧性和促进市场整合的催化剂。然而，对于数字农业转型如何在南非的制度与社会经济语境中展开，尚缺乏系统性分析。本研究考察南非农业数字化的演进轨迹、驱动因素及治理意涵。研究以社会技术系统与数字农业生态系统的整合框架为依托，对2013年至2025年间发表的82份学术与政策文件进行了结构化定性文献分析。研究发现，数字技术采纳模式高度不均衡，反映出资本密集型商业农业与资源受限的小农体系之间的结构性二元分化。尽管南非已建立起相对先进的数字政策架构，但实施碎片化、基础设施制约以及推广能力有限等因素阻碍了包容性数字成果的实现。本研究的贡献在于整合社会技术与生态系统视角以分析新兴经济体的数字转型，并为基于文献的研究提供了透明的分析方案。政策启示强调，需通过协调治理、农村互联互通投资以及有针对性的支持机制，确保公平的数字转型。","International Journal of Business Ecosystem and Strategy (2687-2293)","2026-10-09T00:00:00Z",80,{"impact":19,"substance":18,"depth":19,"authority":20,"freshness":424,"relevant":22,"comment":478},"基于82份文献的系统性分析，揭示南非数字农业的结构性二元分化与治理碎片化，对新兴经济体数字乡村研究有参考价值。",[480],{"name":474,"url":471},[482,27,57,483,484],"数字农业","南非农业","农村数字治理",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":488},{"candidates":489,"agricultural_evidence":48},[490,495,500,504],{"code":46,"score":47,"supported":48,"title":491,"abstract":493,"tags":494},[492],"digital agriculture",[482,492],[482,27],{"code":33,"score":496,"supported":48,"title":497,"abstract":498,"tags":499},4,[],[58],[57],{"code":69,"score":21,"supported":48,"title":501,"abstract":502,"tags":503},[],[72],[],{"code":75,"score":21,"supported":48,"title":505,"abstract":506,"tags":507},[],[78],[],[509,510],"南非 数字农业 转型","南非 小农户 数字鸿沟","南非数字农业转型-4601","10.36096\u002Fijbes.v8i4.1274",{"doi":512,"openalex_id":514,"authors":515,"venue":474,"cited_by_count":138,"oa_url":471,"card":519,"direction":144,"ingested_from":147},"W7221113328",[516],{"name":517,"orcid":518},"Mokgadi Julia Ngoepe-Ntsoane","https:\u002F\u002Forcid.org\u002F0000-0001-7995-4824",{"tldr":520,"method":521,"finding":522,"direction":144,"opportunity":523},"系统分析南非农业数字化轨迹、驱动因素与治理影响，揭示数字鸿沟与政策碎片化。","社会技术系统与数字农业生态框架，对82份2013-2025年文献政策进行结构化质","数字采用高度不均，商业农业与小农二元分化；政策先进但实施碎片化、基建与推广能力不足阻碍包容性转型。","可延伸至新兴经济体小农数字包容性治理机制与农村连接性投资评估的实证研究。","2026-10-10T23:30:34.991942Z"]
