Its return in 2006 and subsequent spread is consistent with a broader phenomenon we term the erosion of climatic pest barriers: seasonal thermal conditions that have historically suppressed or excluded pest populations, and which appear to be weakening as winters warm. Warming may facilitate Medfly persistence by relaxing overwintering limitation, although reinvasion pressure, host availability, fruit movement, and surveillance and management practices likely also contribute. In Mazandaran, growers report substantial on‐tree citrus losses during heavy infestation years, and pest‐induced fruit wounding may provide infection courts for common postharvest fungal pathogens, compounding losses for smallholder producers. Current management relies heavily on organophosphate insecticides, particularly malathion, whose hazard classification and associated risks are well documented, even though realized exposure‐related risk in practice depends on application conditions. We situate the Mazandaran case within a broader global pattern of climate‐associated pest range expansion and weakened biological control, and argue that resilience‐based alternatives—including the Sterile Insect Technique, entomopathogenic agents, and threshold‐guided digital monitoring, embedded within climate‐smart agriculture frameworks—offer a technically proven, though not yet regionally established, pathway forward. We propose that climatic pest barriers merit recognition as an ecosystem service whose erosion under warming carries implications for temperate agricultural systems beyond this case.","地中海实蝇（Ceratitis capitata，Wiedemann；双翅目：实蝇科），俗称地中海果蝇，在1984年明显被根除后，重新出现在伊朗北部的马赞德兰省——该省估计占全国水果作物的25%和柑橘产量的约80%——这一根除结果与多年信息素诱捕监测未再捕获到该虫的情况一致。其2006年的重现及随后的扩散，与我们所称的“气候性有害生物屏障侵蚀”这一更广泛现象相符：历史上抑制或排除有害生物种群的季节性热条件，似乎正随着冬季变暖而减弱。气候变暖可能通过放宽越冬限制而促进地中海实蝇的存续，尽管再入侵压力、寄主可获得性、水果调运以及监测和管理实践也可能起作用。在马赞德兰，种植者报告在严重侵染年份柑橘树上果实损失巨大，且有害生物造成的果实伤口可能为常见的采后真菌病原体提供侵染位点，加剧了小农户的损失。当前的管理严重依赖有机磷杀虫剂，尤其是马拉硫磷，其危害分类及相关风险已有充分记录，尽管实际中与暴露相关的现实风险取决于施药条件。我们将马赞德兰的案例置于气候相关的有害生物分布区扩张和生物防治减弱的更广泛全球格局中，并认为基于韧性的替代方案——包括昆虫不育技术、昆虫病原制剂和阈值引导的数字监测，嵌入气候智慧型农业框架内——提供了一条技术上经过验证但尚未在区域内建立的可行路径。我们提出，气候性有害生物屏障值得被认定为一种生态系统服务，其在变暖下的侵蚀对温带农业系统的影响超越了本案例。",null,"Plant-Environment Interactions","2026-09-24T00:00:00Z","论文",10,false,78,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,21,13,8,1,"以伊朗马赞德兰地中海实蝇复现为案例，提出气候性害虫屏障退化概念，并给出昆虫不育技术、数字化阈值监测等气候智慧农业路径，对暖冬区农业植保与粮食安全具参考价值。",[24],{"name":10,"url":6},[26,27,28,29,30],"智慧农业","粮食安全","气候智慧农业","柑橘产业","害虫监测",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},"A8","yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[],{"status":39,"locked":14,"version":40,"method":41,"evidence":42},"classified","2026-10-22.2","rules",{"candidates":43,"agricultural_evidence":46},[44,51,59,66,73,80,87],{"code":32,"score":45,"supported":46,"title":47,"abstract":49,"tags":50},9,true,[48],"food security",[],[27],{"code":52,"score":53,"supported":46,"title":54,"abstract":55,"tags":58},"B2",6,[],[56,57],"柑橘","citrus",[],{"code":60,"score":53,"supported":46,"title":61,"abstract":62,"tags":65},"G2",[],[63,64],"小农户","smallholder",[],{"code":67,"score":53,"supported":46,"title":68,"abstract":69,"tags":72},"H6",[],[70,71],"生态系统服务","ecosystem service",[],{"code":74,"score":75,"supported":46,"title":76,"abstract":77,"tags":79},"I1",4,[],[78],"smart agriculture",[26],{"code":81,"score":82,"supported":46,"title":83,"abstract":84,"tags":86},"F4",3,[],[85],"生物防治",[],{"code":88,"score":21,"supported":14,"title":89,"abstract":90,"tags":91},"H7",[],[],[28],[93,94],"地中海实蝇 马赞德兰 柑橘","气候变暖 害虫越冬 粮食安全","地中海实蝇马赞德兰柑橘-3546",2,"10.1002\u002Fpei3.70216",{"doi":97,"openalex_id":99,"authors":100,"venue":10,"cited_by_count":110,"oa_url":6,"card":111,"direction":117,"ingested_from":118},"W7214309725",[101,104,106,108],{"name":102,"orcid":103},"Mostafa Farajpour","https:\u002F\u002Forcid.org\u002F0000-0003-4223-502X",{"name":105,"orcid":9},"Shahab Mirinejad",{"name":107,"orcid":9},"Mitra Moezipour",{"name":109,"orcid":9},"Mohammad Sadat‐Hosseini",0,{"tldr":112,"method":113,"finding":114,"direction":115,"opportunity":116},"以伊朗马赞德兰省地中海实蝇重现为例，提出气候害虫屏障侵蚀概念，探讨暖冬致害虫复苏威胁粮食安全。","结合害虫监测历史、农户损失报告与文献综述，分析暖冬对越冬限制的放松。","暖冬削弱气候害虫屏障，使地中海实蝇重新定殖并扩散，威胁柑橘等作物生产与粮食安全。","农业绿色发展与碳","可量化气候害虫屏障作为生态系统服务的价值，并开发阈值引导的数字监测与气候智慧型害虫管理方案。","智慧农业 \u002F 农业物联网","openalex","2026-09-26T23:30:12.754871Z",{"total":53,"page":21,"page_size":53,"items":121},[122,201,292,360,431,532],{"id":123,"title":124,"url":125,"summary":126,"summary_zh":127,"content":9,"source_name":128,"source_url":125,"published_at":129,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":130,"score_detail":131,"sources":134,"tags":136,"primary_topic":138,"secondary_topics":139,"classification":140,"search_phrases":183,"slug":186,"view_count":96,"doi":187,"paper":188,"created_at":200},3826,"From Dry Fields To Smart Resilience: Climate-Smart Agriculture, Digital Early-Warning Systems And Household Food Security In Chivi District, Zimbabwe","https:\u002F\u002Fdoi.org\u002F10.36923\u002Fsq.v3i1.435","This paper examines how climate-smart agriculture (CSA) and digital early-warning systems can jointly support household food-security resilience in Chivi District, a drought-prone area of south-eastern Zimbabwe dominated by rain-fed smallholder agriculture. Using a structured qualitative evidence synthesis with a district-centred case orientation, the study reviews 47 academic, policy and institutional sources published from 2021 to 14 September 2026. The study prioritises direct Chivi evidence, while using Zimbabwean, southern African, and wider African evidence comparatively where district-specific studies are limited. The synthesis identifies six interrelated themes concerning climate shocks, CSA adoption, small grains and water management, digital early warning, gender and institutional capacity, and integrated resilience. The findings indicate that CSA can strengthen food security when extension, inputs, finance, and markets support conservation agriculture, crop diversification, small grains, soil-fertility management, and water harvesting. However, digital early-warning information contributes to resilience only when it is timely, trusted, localised and translated into feasible action. Accordingly, the paper's principal contribution is an integrated smart-resilience framework centred on an information-to-action pathway: climate information can influence household food-security resilience only when farmers have viable adaptation options and the material, social and institutional capacity to act. The paper therefore treats digital information, agronomic adaptation, gender, household resources and local institutions as interdependent rather than separate interventions.","本文考察气候智慧型农业（climate-smart agriculture, CSA）与数字预警系统如何共同支撑津巴布韦东南部干旱易发区奇维（Chivi）地区以雨养小农农业为主的家庭粮食安全韧性。研究采用以地区为中心的案例导向结构化定性证据综合方法，梳理了2021年至2026年9月14日期间发表的47份学术、政策与机构文献。研究优先采用奇维地区的直接证据，在地区性专门研究有限时，则比较性地参考津巴布韦、南部非洲及更广泛非洲的证据。该综合识别出六个相互关联的主题，涉及气候冲击、气候智慧型农业采纳、小粒谷物与水资源管理、数字预警、性别与制度能力，以及综合韧性。研究结果表明，当推广服务、投入品、金融和市场支持保护性农业、作物多样化、小粒谷物、土壤肥力管理和集水时，气候智慧型农业能够增强粮食安全。然而，数字预警信息只有在及时、可信、本地化并转化为可行行动时，才能促进韧性。因此，本文的主要贡献在于提出了一个以信息到行动路径为核心的综合智慧韧性框架：气候信息只有在农民拥有可行的适应选项以及采取行动所需的物质、社会和制度能力时，才能影响家庭粮食安全韧性。据此，本文将数字信息、农艺适应、性别、家庭资源和地方制度视为相互依存的干预措施，而非彼此分离的干预措施。","Sustainability Quest","2026-09-29T00:00:00Z",56,{"impact":20,"substance":17,"depth":132,"authority":53,"freshness":20,"relevant":21,"comment":133},16,"以津巴布韦Chivi区为案例的定性证据综述，提出信息到行动的气候智慧农业韧性框架，对数字预警落地条件有参考价值，但属区域案例研究，公共影响有限。",[135],{"name":128,"url":125},[26,27,63,28,137],"数字预警",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":14,"version":40,"method":41,"evidence":141},{"candidates":142,"agricultural_evidence":46},[143,148,153,160,167,171,177],{"code":32,"score":144,"supported":46,"title":145,"abstract":146,"tags":147},15,[48],[27,48],[27],{"code":74,"score":149,"supported":46,"title":150,"abstract":151,"tags":152},12,[78],[78],[26],{"code":88,"score":154,"supported":46,"title":155,"abstract":156,"tags":159},7,[],[157,158],"干旱","drought",[28],{"code":161,"score":53,"supported":46,"title":162,"abstract":163,"tags":166},"H2",[],[164,165],"土壤","soil",[],{"code":60,"score":75,"supported":46,"title":168,"abstract":169,"tags":170},[],[64],[63],{"code":172,"score":82,"supported":46,"title":173,"abstract":174,"tags":176},"H3",[],[175],"水资源",[],{"code":178,"score":82,"supported":46,"title":179,"abstract":180,"tags":182},"H8",[],[181],"conservation agriculture",[],[184,185],"气候智慧农业 数字预警 智慧农业 粮食安全","气候智慧农业 数字预警","气候智慧农业数字预警智慧农业粮食安全-3826","10.36923\u002Fsq.v3i1.435",{"doi":187,"openalex_id":189,"authors":190,"venue":128,"cited_by_count":110,"oa_url":125,"card":194,"direction":117,"ingested_from":118},"W7214743351",[191],{"name":192,"orcid":193},"Victor Madziyauswa","https:\u002F\u002Forcid.org\u002F0000-0002-6122-6666",{"tldr":195,"method":196,"finding":197,"direction":198,"opportunity":199},"综述津巴布韦Chivi地区气候智慧农业与数字预警系统如何共同提升家庭粮食安全韧性。","结构化定性证据综合，分析47份2021-2026年学术、政策与机构文献。","数字预警须及时、可信、本地化并转化为可行行动，且需配套适应选项与能力才能提升韧性。","数字乡村与农业信息化","可实证检验“信息—行动”路径，研究数字预警与农户适应能力、性别和制度条件的交互机制。","2026-09-30T23:30:09.849166Z",{"id":202,"title":203,"url":204,"summary":205,"summary_zh":206,"content":9,"source_name":207,"source_url":204,"published_at":208,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":209,"score_detail":210,"sources":212,"tags":214,"primary_topic":217,"secondary_topics":218,"classification":229,"search_phrases":270,"slug":273,"view_count":110,"doi":274,"paper":275,"created_at":291},5478,"Characterisation 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":20,"substance":17,"depth":144,"authority":53,"freshness":20,"relevant":21,"comment":211},"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。",[213],{"name":207,"url":204},[27,63,28,215,216],"农业推广","津巴布韦",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[219,224],{"code":60,"slug":220,"name":221,"path":222,"parent_code":223},"farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",{"code":88,"slug":225,"name":226,"path":227,"parent_code":228},"climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":39,"locked":14,"version":40,"method":41,"evidence":230},{"candidates":231,"agricultural_evidence":46},[232,236,240,246,252,259,266],{"code":32,"score":144,"supported":46,"title":233,"abstract":234,"tags":235},[48],[27,48],[27],{"code":60,"score":144,"supported":46,"title":237,"abstract":238,"tags":239},[64],[63,64],[63],{"code":88,"score":13,"supported":46,"title":241,"abstract":242,"tags":245},[],[243,157,244,158],"气候变化","climate change",[28],{"code":247,"score":154,"supported":46,"title":248,"abstract":249,"tags":251},"G1",[],[215,250],"agricultural extension",[215],{"code":253,"score":53,"supported":46,"title":254,"abstract":255,"tags":258},"A3",[],[256,257],"玉米","maize",[],{"code":260,"score":53,"supported":46,"title":261,"abstract":262,"tags":265},"G3",[],[263,264],"农村金融","rural finance",[],{"code":74,"score":82,"supported":46,"title":267,"abstract":268,"tags":269},[],[78],[],[271,272],"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":274,"openalex_id":276,"authors":277,"venue":207,"cited_by_count":110,"oa_url":9,"card":286,"direction":117,"ingested_from":118},"W7223029383",[278,281,284],{"name":279,"orcid":280},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":282,"orcid":283},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":285,"orcid":9},"Patience Mutopo",{"tldr":287,"method":288,"finding":289,"direction":198,"opportunity":290},"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":293,"title":294,"url":295,"summary":296,"summary_zh":297,"content":9,"source_name":207,"source_url":295,"published_at":208,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":298,"score_detail":299,"sources":302,"tags":304,"primary_topic":305,"secondary_topics":306,"classification":311,"search_phrases":340,"slug":343,"view_count":110,"doi":344,"paper":345,"created_at":359},5475,"Adoption of Climate-Smart Conservation Agriculture in Improving Food Security in Zimbabwe: The Case of Marondera District, Zimbabwe","https:\u002F\u002Fdoi.org\u002F10.71458\u002Fwby9rf15","Climate change is negatively impacting the global community and local communities in the Southern African Development Community (SADC) region. Extreme weather events are occurring more frequently, posing a threat to human lives and well-being. Climate change-induced disasters have exacerbated the risks of hunger and under nutrition through reduced yields of agricultural crops. The detrimental effects of climate change are particularly seen in Zimbabwe. It is best to use climate-smart agriculture (CSA) in the smallholder agricultural sector, which produces the majority of the nation's food. Therefore, it is important to learn lessons from past events and manage risks effectively as part of an integrated set of interventions directed at mitigating the harmful impacts of disasters and risks. The research explores community adaptation and coping strategies in addressing the effects of climate change on food security using Marondera District as a case study. The research was conducted using the qualitative research methodology. Data were collected from a population of 50 people that included smallscale farmers, Agritex officers, extension officers, non-governmental organisation (NGO) representatives, village herdsman and the chief. Documentary research was analysed thematically. The research concludes that climate change has had a negative impact on food security. It affected all the four dimensions of food security, that is; food availability, food accessibility, food utilisation and food systems stability. In response, various projects aimed at ensuring community resilience to cope in the face of climatological hazards have been implemented by NGOs, government institutions and other actors, with community members being key stakeholder. The research recommends continued mobilisation of social protection interventions, building of resilient agricultural systems to make them more resilient to climate change and improving the management of the environment to ensure effectiveness in efforts to mitigate the impact of climate change on food security.","气候变化正在对全球社会以及南部非洲发展共同体（SADC）区域的当地社区产生负面影响。极端天气事件发生频率增加，对人类生命和福祉构成威胁。气候变化引发的灾害通过降低农作物产量，加剧了饥饿和营养不足的风险。气候变化的不利影响在津巴布韦尤为显著。在小农农业部门——该部门生产了全国大部分粮食——最好采用气候智能型农业（CSA）。因此，重要的是从过去的事件中吸取教训，并作为旨在减轻灾害和风险有害影响的一套综合干预措施的一部分，有效管理风险。本研究以马龙德拉区为案例，探讨社区在应对气候变化对粮食安全影响方面的适应和应对策略。研究采用定性研究方法开展。数据从50人的群体中收集，包括小规模农户、Agritex官员、推广官员、非政府组织（NGO）代表、村级牧民和酋长。文献研究进行了主题分析。研究得出结论，气候变化对粮食安全产生了负面影响。它影响了粮食安全的所有四个维度，即粮食可供性、粮食可及性、粮食利用和粮食系统稳定性。作为回应，非政府组织、政府机构和其他行为体实施了旨在确保社区抵御气候灾害能力的各类项目，社区成员是关键利益相关者。研究建议继续动员社会保护干预措施，建设有韧性的农业系统以使其更能抵御气候变化，并改善环境管理，以确保减轻气候变化对粮食安全影响的努力取得实效。",54,{"impact":20,"substance":17,"depth":300,"authority":53,"freshness":20,"relevant":21,"comment":301},14,"以津巴布韦Marondera区为案例的定性研究，探讨气候智慧型保护性农业对粮食安全四维度的影响，属区域案例研究，国际借鉴价值有限，不建议进入每日精选。",[303],{"name":207,"url":295},[27,63,28,216],{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[307],{"code":178,"slug":308,"name":309,"path":310,"parent_code":228},"sustainable-agriculture","可持续与保护性农业","\u002Ftopic\u002Fenvironment\u002Fsustainable-agriculture",{"status":39,"locked":14,"version":40,"method":41,"evidence":312},{"candidates":313,"agricultural_evidence":46},[314,318,322,326,330,334],{"code":32,"score":144,"supported":46,"title":315,"abstract":316,"tags":317},[48],[27,48],[27],{"code":178,"score":20,"supported":46,"title":319,"abstract":320,"tags":321},[181],[],[],{"code":88,"score":154,"supported":46,"title":323,"abstract":324,"tags":325},[],[243,244],[28],{"code":60,"score":75,"supported":46,"title":327,"abstract":328,"tags":329},[],[64],[63],{"code":74,"score":82,"supported":46,"title":331,"abstract":332,"tags":333},[],[78],[],{"code":335,"score":82,"supported":46,"title":336,"abstract":337,"tags":339},"I7",[],[338],"研究方法",[],[341,342],"Marondera 气候智慧农业","津巴布韦 小农户 粮食安全","Marondera气候智慧农业-5475","10.71458\u002Fwby9rf15",{"doi":344,"openalex_id":346,"authors":347,"venue":207,"cited_by_count":110,"oa_url":9,"card":354,"direction":117,"ingested_from":118},"W7223010488",[348,351],{"name":349,"orcid":350},"Irony Mazuruse","https:\u002F\u002Forcid.org\u002F0009-0007-5600-7825",{"name":352,"orcid":353},"Judith Chokumanyara","https:\u002F\u002Forcid.org\u002F0009-0000-7386-9960",{"tldr":355,"method":356,"finding":357,"direction":115,"opportunity":358},"研究津巴布韦Marondera地区小农户采用气候智能型保护性农业对粮食安全的影响。","定性研究，访谈50名小农户、推广员、NGO代表等，并进行主题分析。","气候变化损害粮食安全四个维度，多方项目提升了社区抗灾韧性。","可量化气候智能型保护性农业对粮食安全四维度的贡献，并评估数字推广工具在其中的作用。","2026-10-21T23:30:08.757283Z",{"id":361,"title":362,"url":363,"summary":364,"summary_zh":365,"content":9,"source_name":366,"source_url":363,"published_at":367,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":368,"score_detail":369,"sources":373,"tags":375,"primary_topic":379,"secondary_topics":380,"classification":388,"search_phrases":412,"slug":415,"view_count":21,"doi":416,"paper":417,"created_at":430},5308,"Geopolitics and food security: A comprehensive review of emerging risks and responses","https:\u002F\u002Fdoi.org\u002F10.51200\u002Fjsffs.v2i2.7666","This review paper examines the relationship between geopolitics and food security through a Systematic Literature Review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. A total of 15 peer-reviewed journal articles published between 2015 and 2026 were reviewed to identify emerging geopolitical risks and responses affecting global food systems. The study synthesizes literature on armed conflicts, trade restrictions, climate change, supply chain disruptions, energy market instability, and technological transformation in agriculture. The findings identified four major themes. First, geopolitical conflicts and protectionist trade policies significantly disrupt global food supply chains and increase food price volatility. Second, climate-related shock such as droughts, floods, and extreme weather events intensifies food insecurity, particularly in import-dependent and developing economies. Third, weaknesses in global logistics and energy dependence expose food systems to external shocks and market instability. Fourth, technological innovations, including smart farming, precision agriculture, and digital monitoring systems, play an increasingly important role in strengthening agricultural productivity, improving resource efficiency, and enhancing resilience against geopolitical and environmental uncertainties. The policy implications of this study include strengthening regional food reserves, diversifying import sources, investing in climate-resilient agriculture, promoting the adoption of smart farming technologies, and enhancing institutional cooperation between governments and international organizations. The relevance of smart farming is increasingly evident, as precision agriculture, Internet of Things (IoT)-based monitoring systems, and data-driven farming technologies play a critical role in improving productivity, reducing resource inefficiency, and enhancing food system resilience under geopolitical stress. The study contributes to a broader understanding of how geopolitical dynamics shape food security and provides recommendations for building sustainable, resilient, and technology-driven food systems in an increasingly uncertain global environment.","本文通过遵循系统评价与荟萃分析首选报告条目（Preferred Reporting Items for Systematic Reviews and Meta-Analyses）框架的系统文献综述，考察地缘政治与粮食安全之间的关系。共 review 了2015年至2026年间发表的15篇同行评审期刊论文，以识别影响全球粮食系统的新兴地缘政治风险与应对措施。本研究综合了关于武装冲突、贸易限制、气候变化、供应链中断、能源市场不稳定以及农业技术转型的文献。研究结果识别出四大主题。第一，地缘政治冲突和保护主义贸易政策显著扰乱全球粮食供应链并加剧粮食价格波动。第二，干旱、洪水和极端天气事件等气候相关冲击加剧粮食不安全，尤其是在依赖进口的经济体和发展中经济体中。第三，全球物流的薄弱环节和能源依赖使粮食系统暴露于外部冲击和市场不稳定之中。第四，包括智慧农业、精准农业和数字监测系统在内的技术创新，在增强农业生产力、提高资源效率以及增强应对地缘政治和环境不确定性的韧性方面发挥着日益重要的作用。本研究的政策启示包括加强区域粮食储备、多元化进口来源、投资气候韧性农业、促进智慧农业技术的采用，以及加强政府与国际组织之间的制度合作。智慧农业的相关性日益明显，因为精准农业、基于物联网（IoT）的监测系统和数据驱动农业技术在提高生产力、减少资源低效以及增强地缘政治压力下粮食系统韧性方面发挥着关键作用。本研究有助于更广泛地理解地缘政治动态如何塑造粮食安全，并为在日益不确定的全球环境中构建可持续、有韧性且技术驱动的粮食系统提供建议。","Journal of Smart Farming and Food Security","2026-10-19T00:00:00Z",77,{"impact":17,"substance":370,"depth":371,"authority":19,"freshness":45,"relevant":21,"comment":372},20,17,"系统综述梳理地缘政治与粮食安全风险，并强调智慧农业的韧性价值，具政策与产业参考意义，但属综述性论文，非突破性成果。",[374],{"name":366,"url":363},[26,376,27,377,378],"农业供应链","精准农业","地缘政治",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[381,382],{"code":88,"slug":225,"name":226,"path":227,"parent_code":228},{"code":383,"slug":384,"name":385,"path":386,"parent_code":387},"I5","agricultural-iot","物联网传感与边缘计算","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-iot","I",{"status":39,"locked":14,"version":40,"method":41,"evidence":389},{"candidates":390,"agricultural_evidence":46},[391,395,401,405],{"code":32,"score":144,"supported":46,"title":392,"abstract":393,"tags":394},[48],[27,48],[27],{"code":74,"score":396,"supported":46,"title":397,"abstract":398,"tags":400},11,[],[26,377,399],"precision agriculture",[26,377],{"code":88,"score":45,"supported":46,"title":402,"abstract":403,"tags":404},[],[243,157,244],[],{"code":383,"score":45,"supported":46,"title":406,"abstract":407,"tags":411},[],[408,409,410],"物联网","internet of things","IoT",[],[413,414],"地缘政治 粮食安全","智慧农业 粮食系统韧性","地缘政治粮食安全-5308","10.51200\u002Fjsffs.v2i2.7666",{"doi":416,"openalex_id":418,"authors":419,"venue":366,"cited_by_count":110,"oa_url":363,"card":425,"direction":117,"ingested_from":118},"W7222902031",[420,422],{"name":421,"orcid":9},"Parameswaran Mahendran",{"name":423,"orcid":424},"Wong Sing Yun","https:\u002F\u002Forcid.org\u002F0000-0001-5776-8852",{"tldr":426,"method":427,"finding":428,"direction":117,"opportunity":429},"系统综述地缘政治风险对粮食安全的影响及应对，强调智慧农业的韧性作用。","按PRISMA框架系统综述2015-2026年15篇同行评议文献。","冲突、贸易限制、气候与能源冲击威胁粮食安全，智慧农业可提升韧性与效率。","可量化研究物联网与精准农业在地缘政治冲击下对粮食系统韧性的实证贡献。","2026-10-19T23:30:07.850994Z",{"id":432,"title":433,"url":434,"summary":435,"summary_zh":436,"content":9,"source_name":437,"source_url":434,"published_at":438,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":439,"score_detail":440,"sources":442,"tags":444,"primary_topic":447,"secondary_topics":448,"classification":451,"search_phrases":514,"slug":517,"view_count":110,"doi":518,"paper":519,"created_at":531},5185,"When the rains are too much: El Niño, Smallholder Farmers and Food Security in Western Kenya","https:\u002F\u002Fdoi.org\u002F10.18697\u002Fajfand.155.ed182","When the rains are too much: El Niño, Smallholder Farmers and Food Security in Western Kenya For generations, farmers in Western Kenya have watched the skies carefully. The arrival, duration, and distribution of rainfall have traditionally provided important signals about when to prepare land, plant, weed, and harvest. But these signals are becoming increasingly difficult to read. Climate change is altering rainfall patterns, while increasingly frequent extreme weather events are making farming more uncertain. The current outlook for the October–December 2026 season brings this challenge sharply into focus. The IGAD Climate Prediction and Applications Centre (ICPAC) forecasts a wetter-than-normal season across much of the Greater Horn of Africa. The Lake Victoria Basin, which includes large parts of Western Kenya, is among the areas with a high likelihood of receiving more than 400 mm of seasonal rainfall. ICPAC reports that El Niño has developed and is expected to strengthen, while a positive Indian Ocean Dipole is also expected—climate conditions that are commonly associated with enhanced rainfall in the region, and is likely to run into February of 2027. But what does this mean for the smallholder farmer? The first point is that more rainfall does not necessarily mean more food. For a farmer whose livelihood depends almost entirely on rain-fed agriculture, abundant rainfall can be a blessing. It can replenish streams and water sources, improve soil moisture, restore pasture and create favourable conditions for crop production. If well distributed, the rains could contribute to improved harvests and household food supplies. The problem arises when rainfall is too intense, too concentrated or poorly distributed. A farmer may receive a great deal of rain in a few days and then experience a dry spell. Another farmer a few kilometres away may receive considerably less. Heavy downpours can cause flooding, waterlogging and soil erosion. Seeds may be washed away soon after planting. Young crops can be submerged or damaged. Valuable topsoil and nutrients can be carried away, reducing the productivity of land in subsequent seasons. This is particularly important in Western Kenya, where many households depend on small parcels of land for both food and income. A failed or damaged crop is not simply an agricultural loss. It can mean less food in the household, less money for school fees and health care, and fewer resources to purchase nutritious foods. The food-security paradox We must, therefore, look beyond agricultural production to food and nutrition security. A household may produce enough maize yet still have a poor diet if vegetables, legumes, fruits, milk, eggs or other foods are unavailable or unaffordable. Climate shocks can reduce this diversity. When crops are damaged, families may depend more heavily on whatever staple food remains available. This is why climate resilience must also be nutrition-sensitive. Western Kenya has a rich agricultural tradition and considerable potential for diversified food production. Farmers grow cereals, legumes, vegetables and root crops and keep livestock and poultry. Such diversity is not merely an agricultural advantage; it is a nutritional resource. It can provide different foods, spread risk and generate income at different times of the year. Climate adaptation should, therefore, not encourage farmers simply to produce more of one crop. It should help them build diverse and resilient farming systems. Women carry a large part of the burden The impact of erratic and excessive rainfall also has a gender dimension. Women in smallholder households are often deeply involved in food production, processing, preparation and household nutrition. When harvests fail, or food prices rise, women frequently have to find ways of stretching limited household resources to feed the family. When roads become impassable or markets are disrupted, women may have greater difficulty accessing food and agricultural inputs. When water sources are contaminated or damaged, household responsibilities can become even more demanding. Climate adaptation must therefore deliberately include women—not simply as beneficiaries, but as decision-makers, innovators, farmers and leaders. Young people must also be part of the solution There is another group that deserves greater attention: young people. Western Kenya cannot build climate-resilient agriculture while treating agriculture as an occupation of the past. Young people need to see opportunities in modern farming, agro-processing, food safety, climate information services, irrigation, digital agriculture and agricultural entrepreneurship. The increasing unpredictability of climate may actually provide an opportunity to make agriculture more innovative. Young people can help introduce new technologies, improve access to climate information, develop value-added products and create businesses around food production and processing. From forecasting to action The availability of a climate forecast is useful only if it reaches the people who need it in time. Farmers need information that answers practical questions: When should I plant? Which crops or varieties are appropriate? How can I protect my soil? What should I do if rainfall becomes excessive? How can I protect harvested food? Where can I obtain reliable seed and other inputs? Seasonal forecasts should, therefore, be translated into local, practical agricultural advice. ICPAC itself emphasizes that seasonal forecasts should be used together with weekly and monthly forecasts and national meteorological information. This requires stronger links between meteorological services, agricultural extension officers, researchers, county governments, farmer organizations and communities. We should also strengthen simple but important measures: water harvesting, drainage, terracing and soil conservation; planting crops and varieties suited to local conditions; maintaining vegetation cover; diversifying crops and livestock; improving storage facilities; and protecting food from moisture and contamination. Prepare before the rain comes The greatest lesson from the current El Niño outlook is perhaps that preparedness must begin before the first heavy rains arrive. Governments and development partners should not wait for floods, damaged roads, destroyed crops or food shortages before responding. Early warning should lead to early action. Farmers should be supported to prepare their farms, protect livestock, secure seed and inputs, strengthen food storage and identify alternative routes to markets. This is particularly important because the same season can produce both opportunities and losses. ICPAC notes that enhanced rainfall can support agricultural production and replenish water resources, but can simultaneously increase the risk of flooding, flash floods and landslides in vulnerable areas. A changing climate requires a different agricultural mindset Perhaps the most important change we need is in the way we think about farming. For too long, agricultural planning has often assumed that rainfall will behave according to a familiar calendar. That assumption is becoming increasingly unsafe. Farmers now have to manage not only too little rain, but also too much rain, rain at the wrong time and rain in the wrong place. The challenge is, therefore, not simply to produce more food. It is to build food systems that can continue providing adequate, diverse, safe and nutritious food under increasingly uncertain climatic conditions. Western Kenya's smallholder farmers should not be left alone to carry this burden. They need science that responds to their realities, extension services that reach them, climate information they can understand and use, financial services that help them manage risk, markets that function during difficult seasons, and policies that recognize the central role of smallholder agriculture in national food and nutrition security, and partners who are willing to appreciate and make use of indigenous knowledge. El Niño should, therefore, be viewed neither simply as a disaster nor automatically as a blessing. It is a climate event whose consequences will depend greatly on our preparedness. The question before us is not merely, “Will the rains come?” They probably will. The more important question is: Will our farmers, food systems and institutions be ready when they do? That is where climate resilience—and ultimately food and nutrition security—will be tested.

While CSA supports food security, addressing land fragmentation, input access and market challenges is essential for sustained impact.","气候变化威胁着撒哈拉以南非洲的小农农业。本研究在穆桑泽地区评估了气候智能型农业（CSA）的采用情况及其对家庭粮食安全的影响。一项涵盖422户家庭的横断面调查采用了HFIAS和HDDS指标。CSA采用率较高（91.7–100%），但受到土地细碎化的制约。所有家庭均实现了粮食安全，平均HDDS为10.78。较高的采用强度与更大的膳食多样性相关，后者通过家庭膳食多样性评分（HDDS）衡量。农民感知到收入和膳食方面的改善，但未感知到可负担性的提升。尽管CSA有助于粮食安全，但解决土地细碎化、投入获取和市场挑战对于持续产生影响至关重要。","Journal of Hunger & Environmental Nutrition","2026-10-12T00:00:00Z",63,{"impact":20,"substance":17,"depth":144,"authority":19,"freshness":45,"relevant":21,"comment":542},"基于422户调查的实证研究，数据扎实但属区域性案例，对国内三农信息化参考价值有限。",[544],{"name":538,"url":535},[27,63,28,546,547],"膳食多样性","卢旺达",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":14,"version":40,"method":41,"evidence":551},{"candidates":552,"agricultural_evidence":46},[553,557,561,565],{"code":32,"score":144,"supported":46,"title":554,"abstract":555,"tags":556},[48],[27,48],[27],{"code":88,"score":154,"supported":46,"title":558,"abstract":559,"tags":560},[],[243,244],[28],{"code":60,"score":75,"supported":46,"title":562,"abstract":563,"tags":564},[],[64],[63],{"code":74,"score":82,"supported":46,"title":566,"abstract":567,"tags":568},[],[78],[],[570,571],"卢旺达 Musanze 气候智慧农业","HFIAS HDDS 粮食安全","卢旺达Musanze气候智慧农业-4883","10.1080\u002F19320248.2026.2739942",{"doi":573,"openalex_id":575,"authors":576,"venue":538,"cited_by_count":110,"oa_url":587,"card":588,"direction":117,"ingested_from":118},"W7221514696",[577,579,581,584],{"name":578,"orcid":9},"Chance Bertine Imboni",{"name":580,"orcid":9},"Jonas Nzabamwita",{"name":582,"orcid":583},"Christophe Mupenzi","https:\u002F\u002Forcid.org\u002F0000-0003-1088-4527",{"name":585,"orcid":586},"Thompson Faraday Ediagbonya","https:\u002F\u002Forcid.org\u002F0000-0003-0878-8851","https:\u002F\u002Fdoi.org\u002F10.6084\u002Fm9.figshare.34398567",{"tldr":589,"method":590,"finding":591,"direction":115,"opportunity":592},"研究卢旺达Musanze地区气候智慧型农业采用的决定因素及其对家庭粮食安全的影响。","对422户进行横截面调查，使用HFIAS和HDDS指标评估。","CSA采用率高但受土地细碎化制约，采用强度越高膳食多样性越好。","可探究土地细碎化下CSA采用强度与粮食安全的长期动态及市场接入的中介作用。","2026-10-14T23:30:10.365561Z"]
