In response, the Water–Energy–Food (WEF) nexus has emerged as an integrated framework for addressing the interdependencies among these critical sectors while enhancing climate resilience. This study mapped and synthesized existing evidence on WEF nexus approaches to climate change adaptation in SSA through a scoping review. Guided by the Arksey and O’Malley framework and reported in accordance with the PRISMA-ScR guidelines, the review involved a systematic search of Scopus, Web of Science, ScienceDirect, SpringerLink, Wiley Online Library, Google Scholar, and relevant grey literature sources. The findings revealed a growing body of research on WEF nexus-based adaptation, with studies predominantly concentrated in Southern Africa, particularly South Africa. Major integrated resource management approaches identified include climate-smart agriculture, integrated water-resources management, renewable energy integration, nexus-based planning, governance and policy integration, and community-based adaptation. Reported outcomes include enhanced climate resilience; improved water, energy, and food security; strengthened livelihoods; increased resource-use efficiency; and improved institutional coordination. However, implementation remains constrained by fragmented governance systems, limited financing, inadequate data, technical capacity deficits, and weak stakeholder engagement. Key enabling factors include policy coherence, institutional collaboration, technological innovation, climate finance, and capacity-building. The review concludes that the WEF nexus provides a valuable framework for advancing climate adaptation and sustainable resource management in SSA.","气候变化对撒哈拉以南非洲（Sub-Saharan Africa, SSA）的水资源可用性、能源安全和粮食生产构成重大威胁，削弱了可持续发展，并加剧了依赖气候敏感型资源的社区的脆弱性。为应对这一挑战，水—能源—粮食（Water–Energy–Food, WEF）纽带关系已作为一种整合性框架出现，用于处理这些关键部门之间的相互依存关系，同时增强气候韧性。本研究通过范围综述，对撒哈拉以南非洲基于WEF纽带关系的气候变化适应方法进行了梳理和综合。综述以Arksey和O’Malley框架为指导，并按照PRISMA-ScR指南进行报告，系统检索了Scopus、Web of Science、ScienceDirect、SpringerLink、Wiley Online Library、Google Scholar及相关灰色文献来源。研究结果显示，基于WEF纽带关系的适应研究不断增多，且主要集中在南部非洲，尤其是南非。已识别的主要整合性资源管理方法包括气候智能型农业、水资源综合管理、可再生能源整合、基于纽带关系的规划、治理与政策整合以及社区为基础适应。已报告的结果包括气候韧性增强、水—能源—粮食安全改善、生计得到加强、资源利用效率提高以及制度协调改善。然而，实施仍受到治理体系碎片化、融资有限、数据不足、技术能力欠缺以及利益相关方参与薄弱等因素制约。关键使能因素包括政策一致性、机构协作、技术创新、气候融资和能力建设。综述认为，WEF纽带关系为推进撒哈拉以南非洲的气候适应和可持续资源管理提供了有价值的框架。",null,"Economies","2026-10-06T00:00:00Z","论文",10,false,70,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,20,17,13,8,1,"该综述系统梳理了撒哈拉以南非洲水-能-粮关联适应气候变化的证据，方法规范、结论可靠，但属区域性研究，对国内三农信息化直接参考价值有限，可作国际视野补充。",[25],{"name":10,"url":6},[27,28,29,30,31],"撒哈拉以南非洲","粮食安全","气候适应","水资源管理","可再生能源",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":47},[45,54,61,68,75],{"code":33,"score":46,"supported":47,"title":48,"abstract":50,"tags":53},18,true,[49],"climate change",[51,29,49,52],"气候变化","climate resilience",[29],{"code":55,"score":56,"supported":47,"title":57,"abstract":58,"tags":60},"A8",7,[],[28,59],"food security",[28],{"code":62,"score":63,"supported":47,"title":64,"abstract":65,"tags":67},"H3",4,[],[66],"水资源",[30],{"code":69,"score":70,"supported":47,"title":71,"abstract":72,"tags":74},"I1",3,[],[73],"smart agriculture",[],{"code":76,"score":22,"supported":14,"title":77,"abstract":78,"tags":79},"J3",[],[],[27],[81,82],"水-能-粮 关联 气候适应","撒哈拉以南非洲 可再生能源 水资源管理 气候适应","水-能-粮关联气候适应-4344",0,"10.3390\u002Feconomies14100456",{"doi":85,"openalex_id":87,"authors":88,"venue":10,"cited_by_count":84,"oa_url":6,"card":94,"direction":100,"ingested_from":101},"W7220736064",[89,92],{"name":90,"orcid":91},"Adetomiwa Kolapo","https:\u002F\u002Forcid.org\u002F0000-0002-0808-1293",{"name":93,"orcid":9},"Deborah Olude",{"tldr":95,"method":96,"finding":97,"direction":98,"opportunity":99},"综述撒哈拉以南非洲水-能-粮纽带应对气候变化的证据与实践路径。","基于Arksey与O'Malley框架和PRISMA-ScR的范围综述，检索七大","研究集中于南部非洲，主要路径含气候智慧型农业与综合水资源管理，但受治理碎片化与资金数据不足制约。","农业绿色发展与碳","可探索数据驱动型WEF纽带决策模型与跨部门治理评估工具在非洲小农户场景的落地研究。","智慧农业 \u002F 农业物联网","openalex","2026-10-07T23:30:09.089887Z",{"total":104,"page":22,"page_size":104,"items":105},6,[106,181,250,320,404,489],{"id":107,"title":108,"url":109,"summary":110,"summary_zh":111,"content":9,"source_name":112,"source_url":109,"published_at":113,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":114,"score_detail":115,"sources":119,"tags":121,"primary_topic":124,"secondary_topics":125,"classification":132,"search_phrases":157,"slug":160,"view_count":22,"doi":161,"paper":162,"created_at":180},4983,"Climate Change and Livelihood Vulnerability among Smallholder Farming Households in the Diffa Region of Niger’s Lake Chad Basin","https:\u002F\u002Fdoi.org\u002F10.9734\u002Fjeai\u002F2026\u002Fv48i104567","Climate change affects agricultural production, on which 80% of rural communities in sub-Saharan Africa depend for their livelihoods. In the Lake Chad Basin, recent fluctuations in hydro-climatic conditions have compromised crop yields and food security, severely affecting smallholder farmers’ well-being. Enhancing their adaptive capacity and resilience is therefore essential for sustainable development. This study assesses smallholder farmers’ vulnerability to climate change-induced extreme weather events in rural areas of the Lake Chad Basin using the Livelihood Vulnerability Index (LVI). Data were collected through questionnaire surveys of 200 farming households across four villages in the Diffa region of Niger. The LVI was calculated using nine components: sociodemographic profile, education and housing, livelihood strategy, social networks, food, water resources, health, land resources, and disasters and climate variability. Results showed that farmers in Kangarwa were the most vulnerable (LVI = 0.58), while those in Boulangou were the least vulnerable (0.51). Digargo and Mamari had similar vulnerability levels (0.55 and 0.56, respectively). Overall, farmers in all four villages were moderately vulnerable. Kangarwa’s higher vulnerability was mainly associated with social networks (0.81), livelihood strategy (0.75), and land resources (0.75). In Boulangou, low vulnerability was linked to water resources (0.12) and sociodemographic conditions (0.35), although land (0.69), livelihood strategy (0.67), and food (0.65) increased vulnerability. These findings can inform interventions to strengthen smallholder farmers’ resilience. Diversifying livelihoods and adopting climate-smart agriculture technologies could enhance adaptive capacity and reduce vulnerability in highly affected areas.","气候变化影响着农业生产，而撒哈拉以南非洲80%的农村社区依赖农业维持生计。在乍得湖流域，近期水文气候条件的波动已危及作物产量和粮食安全，严重影响小农户的福祉。因此，增强其适应能力和韧性对可持续发展至关重要。本研究采用生计脆弱性指数（LVI）评估乍得湖流域农村地区小农户对气候变化引发的极端天气事件的脆弱性。数据通过对尼日尔迪法地区四个村庄200个农户的问卷调查收集。LVI基于九个组成部分计算：社会人口特征、教育与住房、生计策略、社会网络、粮食、水资源、健康、土地资源以及灾害与气候变异性。结果表明，Kangarwa的农户最为脆弱（LVI = 0.58），而Boulangou的农户脆弱性最低（0.51）。Digargo和Mamari的脆弱性水平相近（分别为0.55和0.56）。总体而言，四个村庄的农户均处于中等脆弱水平。Kangarwa较高的脆弱性主要与社会网络（0.81）、生计策略（0.75）和土地资源（0.75）相关。在Boulangou，低脆弱性与水资源（0.12）和社会人口条件（0.35）相关，尽管土地（0.69）、生计策略（0.67）和粮食（0.65）增加了脆弱性。这些发现可为增强小农户韧性的干预措施提供依据。生计多样化和采用气候智能型农业技术可增强高受影响地区的适应能力并降低脆弱性。","Journal of Experimental Agriculture International","2026-10-14T00:00:00Z",65,{"impact":21,"substance":18,"depth":116,"authority":17,"freshness":117,"relevant":22,"comment":118},16,9,"基于200户问卷的LVI实证研究，数据与结论具体，但属区域性学术成果，公共影响有限。",[120],{"name":112,"url":109},[28,122,51,29,123],"小农户","生计脆弱性",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[126],{"code":127,"slug":128,"name":129,"path":130,"parent_code":131},"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":133},{"candidates":134,"agricultural_evidence":47},[135,139,145,149,153],{"code":33,"score":116,"supported":47,"title":136,"abstract":137,"tags":138},[49],[51,49],[51,29],{"code":127,"score":140,"supported":47,"title":141,"abstract":143,"tags":144},15,[142],"smallholder",[122,142],[122],{"code":55,"score":56,"supported":47,"title":146,"abstract":147,"tags":148},[],[28,59],[28],{"code":62,"score":70,"supported":47,"title":150,"abstract":151,"tags":152},[],[66],[],{"code":69,"score":70,"supported":47,"title":154,"abstract":155,"tags":156},[],[73],[],[158,159],"尼日尔 乍得湖流域 小农户","生计脆弱性指数 LVI","尼日尔乍得湖流域小农户-4983","10.9734\u002Fjeai\u002F2026\u002Fv48i104567",{"doi":161,"openalex_id":163,"authors":164,"venue":112,"cited_by_count":84,"oa_url":109,"card":175,"direction":100,"ingested_from":101},"W7221748179",[165,167,169,171,173],{"name":166,"orcid":9},"Issiaka Issaharou Matchi",{"name":168,"orcid":9},"I.

This paper exploits the staggered implementation, beginning in 2018, of China's agricultural insurance reforms covering full production costs and planting income as a quasi-natural experiment. Drawing on provincial panel data from 2013 to 2024, we first develop a multidimensional composite index to capture food production resilience. A staggered difference-in-differences specification is then adopted to systematically assess the causal effect of these reforms on such resilience and to explore the underlying transmission channels. Moreover, from a novel climate change perspective, the analysis examines the heterogeneous treatment effects across varying degrees of climate risk exposure. The empirical findings reveal that the policy-led agricultural insurance reform significantly and robustly enhances China's food production resilience. Mechanism tests indicate that advances in agricultural technology and the expansion of large-scale farming operations serve as important pathways through which the insurance policy takes effect. Further investigation shows that climate change risk positively moderates the policy impact: as climate risk intensifies, the marginal contribution of insurance to resilience becomes stronger. Heterogeneity analysis also demonstrates that the policy effect is more pronounced in western China and in localities with higher rates of disaster-induced losses. Taken together, these results offer solid empirical backing for broadening the pilot programs of full cost and planting income insurance. They also establish a theoretical basis for positioning publicly supported agricultural insurance as an effective instrument for climate change adaptation, providing valuable guidance on strengthening the climate adaptability and resilience of food production to ensure national food security.","在全球气候威胁日益加剧的背景下，增强粮食生产系统的韧性已成为维护国家粮食安全的关键任务。本文以2018年起分阶段实施的中国农业保险覆盖完全生产成本和种植收入的改革为准自然实验，基于2013—2024年省级面板数据，首先构建多维复合指数以刻画粮食生产韧性，继而采用交错双重差分模型系统评估该改革对粮食生产韧性的因果效应并探究其传导机制。此外，本文从气候变化这一新视角出发，考察了不同气候风险暴露程度下的异质性处理效应。实证结果表明，政策主导的农业保险改革显著且稳健地提升了中国粮食生产韧性。机制检验表明，农业技术进步与规模化经营扩张是保险政策发挥作用的重要路径。进一步研究发现，气候变化风险对政策效应具有正向调节作用：随着气候风险加剧，保险对韧性的边际贡献增强。异质性分析还表明，政策效应在中国西部地区以及灾害损失率较高的地区更为显著。综上，上述结果为扩大完全成本保险和种植收入保险试点提供了坚实的经验依据，也为将公共支持的农业保险定位为气候变化适应的有效工具奠定了理论基础，为增强粮食生产的气候适应性与韧性、保障国家粮食安全提供了有价值的政策启示。","Frontiers in Sustainable Food Systems","2026-10-05T00:00:00Z",88,{"impact":191,"substance":192,"depth":193,"authority":194,"freshness":21,"relevant":22,"comment":195},24,23,19,14,"基于2013-2024年省级面板数据的交错DID准自然实验，证实农业保险改革显著提升粮食生产韧性且气候风险具有正向调节作用，方法规范、结论可靠，对完善农业保险试点具有政策参考价值。",[197],{"name":187,"url":184},[28,199,200,29,201],"农业保险","农业政策","生产韧性",{"code":203,"slug":204,"name":205,"path":206,"parent_code":131},"G3","rural-finance","农村金融与保险","\u002Ftopic\u002Frural-services\u002Frural-finance",[208],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":210},{"candidates":211,"agricultural_evidence":47},[212,217,221],{"code":203,"score":140,"supported":47,"title":213,"abstract":215,"tags":216},[214],"agricultural insurance",[199,214],[199],{"code":33,"score":13,"supported":47,"title":218,"abstract":219,"tags":220},[],[51,29,49],[29],{"code":55,"score":56,"supported":47,"title":222,"abstract":223,"tags":224},[],[28,59],[28],[226,227],"农业保险改革 粮食生产韧性","完全成本保险 种植收入保险","农业保险改革粮食生产韧性-4289","10.3389\u002Ffsufs.2026.1954205",{"doi":229,"openalex_id":231,"authors":232,"venue":187,"cited_by_count":84,"oa_url":184,"card":244,"direction":98,"ingested_from":101},"W7220367453",[233,236,238,240,242],{"name":234,"orcid":235},"Changzhe Deng","https:\u002F\u002Forcid.org\u002F0009-0006-0852-5997",{"name":237,"orcid":9},"Maimiao Sun",{"name":239,"orcid":9},"Xueyu Lin",{"name":241,"orcid":9},"Chencan Rao",{"name":243,"orcid":9},"Qiuping Guo",{"tldr":245,"method":246,"finding":247,"direction":98,"opportunity":248},"基于2013-2024省级面板数据，评估中国农业保险改革对粮食生产韧性的因果影响。","多维度韧性指数+交错双重差分，利用2018年起保险改革试点作准自然实验。","保险改革显著提升粮食生产韧性，气候风险越高其边际贡献越强，西部和灾损高地区效果更明显。","可探究保险改革与农业技术、规模化经营的协同机制，及气候风险下保险产品设计与精准赔付的优化路径。","2026-10-06T23:30:05.886883Z",{"id":251,"title":252,"url":253,"summary":254,"summary_zh":255,"content":9,"source_name":256,"source_url":253,"published_at":257,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":258,"score_detail":259,"sources":261,"tags":263,"primary_topic":267,"secondary_topics":272,"classification":274,"search_phrases":301,"slug":304,"view_count":305,"doi":306,"paper":307,"created_at":319},2939,"Climate Change and Food Security in Africa: Harnessing Responsible AI for Sustainable Agricultural Transformation","https:\u002F\u002Fdoi.org\u002F10.56201\u002Fijaes.vol.11.no9.2025.pg79.102","Africa stands at the crossroads of two defining 21st-century challenges: climate change and food insecurity. The continents agricultural systems are increasingly disrupted by rising temperatures, erratic rainfall, and extreme weather events, exacerbating hunger, poverty, and rural vulnerability. At the same time, Artificial Intelligence (AI) presents transformative potential to support climate adaptation, improve agricultural resilience, and enhance food systems governance across Africa. This study undertakes a qualitative content analysis and critical synthesis of 25 peer-reviewed articles, institutional reports, and working papers to examine how AI is currently applied and could be more effectively leveraged for climate-resilient agriculture and food security on the continent. Findings reveal a growing body of innovations, from AIdriven weather forecasting and early warning systems to precision agriculture and supply chain optimization. Yet the study identifies persistent structural limitations, including unreliable data infrastructure, low digital capacity in rural areas, and governance gaps around ethical deployment, data ownership, and equitable access. Through African case studies, the paper explores how localized AI solutions when supported by inclusive policies, multi-stakeholder collaboration, and responsible innovation frameworks can mitigate climate-induced food shocks and drive sustainable development. The paper argues for a strategic alignment between AI deployment and national adaptation plans, emphasizing the need for stronger public-private partnerships, investments in AI-ready infrastructure, and the development of ethical and contextsensitive governance mechanisms.

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":21,"substance":46,"depth":140,"authority":104,"freshness":21,"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},[28,122,334,335,336],"气候智慧农业","农业推广","津巴布韦",{"code":55,"slug":268,"name":269,"path":270,"parent_code":271},[339,340],{"code":127,"slug":128,"name":129,"path":130,"parent_code":131},{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":342},{"candidates":343,"agricultural_evidence":47},[344,348,352,358,364,371,377],{"code":55,"score":140,"supported":47,"title":345,"abstract":346,"tags":347},[59],[28,59],[28],{"code":127,"score":140,"supported":47,"title":349,"abstract":350,"tags":351},[142],[122,142],[122],{"code":33,"score":13,"supported":47,"title":353,"abstract":354,"tags":357},[],[51,355,49,356],"干旱","drought",[334],{"code":359,"score":56,"supported":47,"title":360,"abstract":361,"tags":363},"G1",[],[335,362],"agricultural extension",[335],{"code":365,"score":104,"supported":47,"title":366,"abstract":367,"tags":370},"A3",[],[368,369],"玉米","maize",[],{"code":203,"score":104,"supported":47,"title":372,"abstract":373,"tags":376},[],[374,375],"农村金融","rural finance",[],{"code":69,"score":70,"supported":47,"title":378,"abstract":379,"tags":380},[],[73],[],[382,383],"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":385,"openalex_id":387,"authors":388,"venue":326,"cited_by_count":84,"oa_url":9,"card":397,"direction":100,"ingested_from":101},"W7223029383",[389,392,395],{"name":390,"orcid":391},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":393,"orcid":394},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":396,"orcid":9},"Patience Mutopo",{"tldr":398,"method":399,"finding":400,"direction":401,"opportunity":402},"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。","数字乡村与农业信息化","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":405,"title":406,"url":407,"summary":408,"summary_zh":409,"content":9,"source_name":410,"source_url":407,"published_at":411,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":412,"score_detail":413,"sources":415,"tags":417,"primary_topic":420,"secondary_topics":421,"classification":426,"search_phrases":470,"slug":473,"view_count":84,"doi":9,"paper":474,"created_at":488},5312,"Agricultural Production under Climate Change in Afghanistan: Impacts, Challenges and Adaptation Options (A Review)","https:\u002F\u002Fesrj.edu.af\u002Fesrj\u002Farticle\u002Fview\u002F123","Climate change poses serious challenges to agriculture in Afghanistan, a country largely dependent on rainfed farming and highly vulnerable to water scarcity, drought, and temperature extremes. Understanding the impacts of climate variability and identifying effective adaptation strategies are essential to sustain agricultural productivity and ensure food security. This systematic review synthesizes empirical, modeling, and review studies on climate change effects on Afghan agriculture, assesses adaptation measures, and integrates regional experiences from Pakistan, Iran, Tajikistan, and Uzbekistan. A structured literature search was conducted using peer-reviewed articles, institutional reports, and regional studies published between 2000 and 2025. Studies were selected based on relevance to Afghan agro-ecological systems, climate stressors, and adaptation strategies. We extracted data using a structured table format following PRISMA guidelines, combining national and regional evidence. Findings indicate that water scarcity, prolonged drought, rising temperatures, and erratic precipitation are the main stressors affecting major crops, including wheat, barley, chickpea, maize, and cotton. Yield reductions ranged from 12% to 25% across provinces. Adaptation strategies such as Climate-Smart Agriculture (CSA), efficient irrigation (drip and sprinkler), rainwater harvesting, mulching, and drought- or heat-tolerant crop varieties were most effective. Regional evidence confirms the transferability of these measures under similar agro-climatic conditions. In conclusion, climate change significantly threatens agricultural productivity in Afghanistan. Evidence-based adaptation strategies, supported by coordinated policy and capacity-building initiatives, can enhance resilience, protect rural livelihoods, and ensure sustainable food security.","气候变化对阿富汗农业构成严峻挑战，该国农业在很大程度上依赖雨养耕作，极易受到水资源短缺、干旱和极端温度的影响。理解气候变异的影响并确定有效的适应策略，对于维持农业生产力和保障粮食安全至关重要。本系统综述综合了关于气候变化对阿富汗农业影响的实证研究、模拟研究和综述研究，评估了适应措施，并整合了巴基斯坦、伊朗、塔吉克斯坦和乌兹别克斯坦的区域经验。采用结构化文献检索方法，检索了2000年至2025年间发表的同行评审论文、机构报告和区域研究。研究依据其与阿富汗农业生态系统、气候胁迫因子和适应策略的相关性进行筛选。我们遵循PRISMA指南，采用结构化表格格式提取数据，综合了国家层面和区域层面的证据。研究结果表明，水资源短缺、持续干旱、气温上升和降水不稳定是影响主要作物（包括小麦、大麦、鹰嘴豆、玉米和棉花）的主要胁迫因子。各省产量降幅在12%至25%之间。气候智慧型农业（CSA）、高效灌溉（滴灌和喷灌）、雨水收集、覆盖栽培以及耐旱或耐热作物品种等适应策略最为有效。区域证据证实了这些措施在相似农业气候条件下的可推广性。总之，气候变化显著威胁阿富汗的农业生产力。以协调政策和能力建设举措为支撑的循证适应策略能够增强韧性、保护农村生计并确保可持续的粮食安全。","ESRJ","2026-10-16T00:00:00Z",73,{"impact":46,"substance":18,"depth":19,"authority":17,"freshness":104,"relevant":22,"comment":414},"系统综述整合2000-2025年证据，量化减产12%-25%并提出可迁移的适应策略，对区域农业气候韧性研究有参考价值，但非国内三农政策或产业事件，时效性一般。",[416],{"name":410,"url":407},[264,28,51,418,419],"适应性策略","水资源短缺",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[422],{"code":62,"slug":423,"name":424,"path":425,"parent_code":37},"irrigation","水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation",{"status":40,"locked":14,"version":41,"method":42,"evidence":427},{"candidates":428,"agricultural_evidence":47},[429,433,438,442,449,453,460,464],{"code":33,"score":46,"supported":47,"title":430,"abstract":431,"tags":432},[49],[51,355,49,356],[51],{"code":62,"score":117,"supported":47,"title":434,"abstract":435,"tags":437},[],[436,66,423],"灌溉",[],{"code":55,"score":56,"supported":47,"title":439,"abstract":440,"tags":441},[],[28,59],[28],{"code":443,"score":104,"supported":47,"title":444,"abstract":445,"tags":448},"A2",[],[446,447],"小麦","wheat",[],{"code":365,"score":104,"supported":47,"title":450,"abstract":451,"tags":452},[],[368,369],[],{"code":454,"score":104,"supported":47,"title":455,"abstract":456,"tags":459},"A6",[],[457,458],"棉花","cotton",[],{"code":69,"score":63,"supported":47,"title":461,"abstract":462,"tags":463},[],[73],[264],{"code":465,"score":70,"supported":47,"title":466,"abstract":467,"tags":469},"H6",[],[468],"农业生态",[],[471,472],"阿富汗 气候变化","气候智慧型农业 灌溉","阿富汗气候变化-5312",{"doi":9,"openalex_id":475,"authors":476,"venue":410,"cited_by_count":84,"oa_url":407,"card":483,"direction":100,"ingested_from":101},"W7222907396",[477,479,481],{"name":478,"orcid":9},"Mohammad Shafiq Faieq",{"name":480,"orcid":9},"Mustafa Abid",{"name":482,"orcid":9},"Abdul khalil Afghani",{"tldr":484,"method":485,"finding":486,"direction":98,"opportunity":487},"系统综述气候变化对阿富汗农业的影响、挑战与适应策略。","按PRISMA检索2000-2025年文献，整合阿富汗及周边四国区域证据。","水资源短缺与干旱致主要作物减产12%-25%，气候智慧型农业与节水灌溉最有效。","可研究气候智慧型农业措施在阿富汗及周边干旱区的本地化适配与推广机制。","2026-10-19T23:30:11.285828Z",{"id":490,"title":491,"url":492,"summary":493,"summary_zh":494,"content":9,"source_name":495,"source_url":492,"published_at":496,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":497,"score_detail":498,"sources":500,"tags":502,"primary_topic":505,"secondary_topics":506,"classification":514,"search_phrases":537,"slug":540,"view_count":22,"doi":541,"paper":542,"created_at":555},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":46,"substance":18,"depth":19,"authority":20,"freshness":117,"relevant":22,"comment":499},"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。",[501],{"name":495,"url":492},[264,503,28,288,504],"农业供应链","地缘政治",{"code":55,"slug":268,"name":269,"path":270,"parent_code":271},[507,508],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"code":509,"slug":510,"name":511,"path":512,"parent_code":513},"I5","agricultural-iot","物联网传感与边缘计算","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-iot","I",{"status":40,"locked":14,"version":41,"method":42,"evidence":515},{"candidates":516,"agricultural_evidence":47},[517,521,526,530],{"code":55,"score":140,"supported":47,"title":518,"abstract":519,"tags":520},[59],[28,59],[28],{"code":69,"score":522,"supported":47,"title":523,"abstract":524,"tags":525},11,[],[264,288,289],[264,288],{"code":33,"score":117,"supported":47,"title":527,"abstract":528,"tags":529},[],[51,355,49],[],{"code":509,"score":117,"supported":47,"title":531,"abstract":532,"tags":536},[],[533,534,535],"物联网","internet of things","IoT",[],[538,539],"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":541,"openalex_id":543,"authors":544,"venue":495,"cited_by_count":84,"oa_url":492,"card":550,"direction":100,"ingested_from":101},"W7222902031",[545,547],{"name":546,"orcid":9},"Parameswaran Mahendran",{"name":548,"orcid":549},"Wong Sing Yun","https:\u002F\u002Forcid.org\u002F0000-0001-5776-8852",{"tldr":551,"method":552,"finding":553,"direction":100,"opportunity":554},"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"]
