Rising temperatures, erratic precipitation, extreme weather events, and land degradation are undermining agricultural productivity and destabilizing food access, particularly among marginalized and low-income populations. This paper examines the complex interplay between climate change and food insecurity, drawing on recent empirical studies and cross-regional data to analyze environmental, economic, and social dimensions. It highlights how climate-related disruptions disproportionately affect women, children, indigenous groups, and smallholder farmers, compounding existing structural inequities. The review evaluates current adaptation and mitigation efforts, including climate-smart agriculture, water resource management, and renewable energy integration. It also assesses policy gaps and proposes a holistic, equity-centered framework that integrates sustainable agriculture, community empowerment, and climate resilience. The study emphasizes the urgency of embedding food security into climate policy at all levels to safeguard livelihoods and promote sustainable development in an era of intensifying climate risk.","气候变化正在迅速重塑全球粮食系统，加剧全球北方和全球南方的粮食不安全。气温上升、降水异常、极端天气事件和土地退化正在削弱农业生产力并破坏粮食获取的稳定性，尤其是对边缘化和低收入群体而言。本文借鉴近期实证研究和跨区域数据，分析环境、经济和社会维度，考察气候变化与粮食不安全之间复杂的相互作用。文章强调，与气候相关的扰动对妇女、儿童、原住民群体和小农的影响尤为不成比例，并加剧了现有的结构性不平等。本文评估了当前的适应和减缓努力，包括气候智慧型农业、水资源管理和可再生能源整合。文章还评估了政策缺口，并提出一个以公平为中心的整体框架，将可持续农业、社区赋权和气候韧性相结合。研究强调，在气候风险日益加剧的时代，将粮食安全纳入各级气候政策以保障生计和促进可持续发展具有紧迫性。",null,"JOURNAL OF BIOLOGY AND GENETIC RESEARCH","2026-09-14T00:00:00Z","论文",10,false,78,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},22,18,17,13,8,1,"跨区域综述揭示气候变化对全球粮食安全的系统性冲击，并提出以公平为核心的适应框架，对农业政策与气候韧性建设具参考价值。",[25],{"name":10,"url":6},[27,28,29,30,31],"粮食安全","小农户","气候变化","气候智慧型农业","农业适应",{"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},[45,53,60,68,75,82],{"code":33,"score":46,"supported":47,"title":48,"abstract":50,"tags":52},19,true,[49],"climate change",[29,49,51],"climate resilience",[29,30],{"code":54,"score":55,"supported":47,"title":56,"abstract":57,"tags":59},"A8",7,[],[27,58],"food security",[27],{"code":61,"score":62,"supported":47,"title":63,"abstract":64,"tags":67},"H3",6,[],[65,66],"水资源","water resource",[],{"code":69,"score":62,"supported":47,"title":70,"abstract":71,"tags":74},"H8",[],[72,73],"可持续农业","sustainable agriculture",[],{"code":76,"score":77,"supported":47,"title":78,"abstract":79,"tags":81},"G2",4,[],[80],"smallholder",[28],{"code":83,"score":84,"supported":47,"title":85,"abstract":86,"tags":88},"I1",3,[],[87],"smart agriculture",[],[90,91],"气候智慧型农业 农业适应 气候变化 粮食安全","气候智慧型农业 农业适应","气候智慧型农业农业适应气候变化粮食安全-2508","10.56201\u002Fjbgr.vol.11.no4.2025.pg88.95",{"doi":93,"openalex_id":95,"authors":96,"venue":10,"cited_by_count":99,"oa_url":100,"card":101,"direction":107,"ingested_from":108},"W7212575816",[97],{"name":98,"orcid":9},"Ahmed Farida Mohammed",0,"https:\u002F\u002Fiiardjournals.org\u002Fget\u002FJBGR\u002FVOL. 11 NO. 4 2025\u002FFood Insecurity The Hungry 88-95.pdf",{"tldr":102,"method":103,"finding":104,"direction":105,"opportunity":106},"综述气候变化与粮食不安全的复杂关联，提出以公平为中心的综合应对框架。","基于近期实证研究与跨区域数据，分析环境、经济和社会维度。","气候冲击对妇女、儿童、原住民和小农影响尤甚，需将粮食安全嵌入各级气候政策。","农业绿色发展与碳","可量化气候智能农业与水资源管理对弱势群体粮食安全的公平性效益，填补政策评估空白。","智慧农业 \u002F 农业物联网","openalex","2026-09-15T23:30:08.313374Z",{"total":62,"page":22,"page_size":62,"items":111},[112,187,283,368,450,549],{"id":113,"title":114,"url":115,"summary":116,"summary_zh":117,"content":9,"source_name":118,"source_url":115,"published_at":119,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":120,"score_detail":121,"sources":127,"tags":129,"primary_topic":132,"secondary_topics":133,"classification":139,"search_phrases":163,"slug":166,"view_count":22,"doi":167,"paper":168,"created_at":186},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":122,"depth":123,"authority":124,"freshness":125,"relevant":22,"comment":126},20,16,12,9,"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。",[128],{"name":118,"url":115},[27,28,29,130,131],"气候适应","生计脆弱性",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[134],{"code":76,"slug":135,"name":136,"path":137,"parent_code":138},"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":140},{"candidates":141,"agricultural_evidence":47},[142,146,151,155,159],{"code":33,"score":123,"supported":47,"title":143,"abstract":144,"tags":145},[49],[29,49],[29,130],{"code":76,"score":147,"supported":47,"title":148,"abstract":149,"tags":150},15,[80],[28,80],[28],{"code":54,"score":55,"supported":47,"title":152,"abstract":153,"tags":154},[],[27,58],[27],{"code":61,"score":84,"supported":47,"title":156,"abstract":157,"tags":158},[],[65],[],{"code":83,"score":84,"supported":47,"title":160,"abstract":161,"tags":162},[],[87],[],[164,165],"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":167,"openalex_id":169,"authors":170,"venue":118,"cited_by_count":99,"oa_url":115,"card":181,"direction":107,"ingested_from":108},"W7221748179",[171,173,175,177,179],{"name":172,"orcid":9},"Issiaka Issaharou Matchi",{"name":174,"orcid":9},"I.

Through a comprehensive review of existing literature, case studies, and policy frameworks, the research explores how these adaptive strategies are being implemented across the continent and assesses their effectiveness. The findings reveal that while CSA techniques—such as droughtresistant crop varieties, water-efficient irrigation, and soil management practices—offer tangible benefits to agricultural productivity and resilience, their widespread adoption remains constrained by limited access to finance, inadequate infrastructure, and insufficient extension services. Similarly, agroecological approaches, including crop diversification, agroforestry, and organic farming, have proven successful in fostering sustainable agricultural practices and enhancing biodiversity, yet face significant challenges from prevailing agricultural policies and institutional frameworks that favor large-scale industrial agriculture. The study recommends scaling up the adoption of CSA and agroecology by improving access to financing, technology, and farmer training programs. It also advocates for policy reforms that support agroecological practices and climate adaptation, as well as increased investment in research and development. Additionally, fostering multi-stakeholder collaborations, including public-private partnerships, is critical to overcoming institutional barriers and ensuring the effective implementation of climate adaptation strategies. The conclusion underscores the need for integrated policy frameworks that combine the strengths of CSA and agroecology to build a resilient, sustainable, and food-secure agricultural sector in Africa. By addressing both environmental and socioeconomic challenges, these strategies can significantly contribute to combating the impacts of climate change on African agriculture, ensuring long-term food security and sustainable development.","本研究探讨了气候智能型农业（Climate-Smart Agriculture, CSA）和农业生态学在增强非洲农业应对气候变化韧性和粮食安全方面的作用。通过系统梳理现有文献、案例研究和政策框架，本研究考察了这些适应性策略在非洲大陆的实施情况并评估其有效性。研究发现，尽管气候智能型农业技术——如抗旱作物品种、节水灌溉和土壤管理措施——对提高农业生产力和韧性具有切实效益，但其广泛采用仍受限于融资渠道有限、基础设施不足和推广服务欠缺。同样，农业生态学方法，包括作物多样化、农林业和有机农业，已被证明在促进可持续农业实践和增强生物多样性方面卓有成效，但仍面临来自有利于大规模工业化农业的现行农业政策和制度框架的重大挑战。本研究建议通过改善融资渠道、技术获取和农民培训项目来扩大气候智能型农业和农业生态学的采用。研究还倡导支持农业生态实践和气候适应的政策改革，以及增加研发投入。此外，促进多方利益相关者合作，包括公私合作伙伴关系，对于克服制度障碍和确保气候适应策略的有效实施至关重要。结论强调，需要建立综合性政策框架，将气候智能型农业和农业生态学的优势相结合，以在非洲构建具有韧性、可持续且粮食安全的农业部门。通过同时应对环境和社会经济挑战，这些策略能够为抵御气候变化对非洲农业的影响、确保长期粮食安全和可持续发展作出重大贡献。","IIARD INTERNATIONAL JOURNAL OF GEOGRAPHY AND ENVIRONMENTAL MANAGEMENT","2026-09-21T00:00:00Z",76,{"impact":18,"substance":122,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":197},"系统综述非洲气候智慧型农业与生态农业的适应策略及政策障碍，结论可靠但属文献综述，非突破性成果。",[199],{"name":193,"url":190},[27,201,30,31,202],"非洲农业","生态农业",{"code":54,"slug":204,"name":205,"path":206,"parent_code":207},"yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[209,213],{"code":69,"slug":210,"name":211,"path":212,"parent_code":37},"sustainable-agriculture","可持续与保护性农业","\u002Ftopic\u002Fenvironment\u002Fsustainable-agriculture",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":215},{"candidates":216,"agricultural_evidence":47},[217,221,225,229,238,245,251,256,260],{"code":54,"score":147,"supported":47,"title":218,"abstract":219,"tags":220},[58],[27,58],[27],{"code":69,"score":124,"supported":47,"title":222,"abstract":223,"tags":224},[73],[72],[202],{"code":33,"score":13,"supported":47,"title":226,"abstract":227,"tags":228},[],[29,130,49],[30],{"code":230,"score":125,"supported":47,"title":231,"abstract":232,"tags":237},"H6",[],[233,234,235,236],"生物多样性","农业生态","biodiversity","agroecology",[],{"code":239,"score":62,"supported":47,"title":240,"abstract":241,"tags":244},"H2",[],[242,243],"土壤","soil",[],{"code":61,"score":62,"supported":47,"title":246,"abstract":247,"tags":250},[],[248,249],"灌溉","irrigation",[],{"code":252,"score":77,"supported":47,"title":253,"abstract":254,"tags":255},"J3",[],[201],[201],{"code":83,"score":84,"supported":47,"title":257,"abstract":258,"tags":259},[],[87],[],{"code":261,"score":84,"supported":47,"title":262,"abstract":263,"tags":265},"J1",[],[264],"农业政策",[],[267,268],"气候智慧型农业 非洲","生态农业 粮食安全","气候智慧型农业非洲-3156",5,"10.56201\u002Fijgem.vol.11.no2.2025.pg8.32",{"doi":271,"openalex_id":273,"authors":274,"venue":193,"cited_by_count":22,"oa_url":9,"card":277,"direction":107,"ingested_from":108},"W7213982962",[275],{"name":276,"orcid":9},"Ayobami Samuel Owoyemi",{"tldr":278,"method":279,"finding":280,"direction":105,"opportunity":281},"综述气候智慧型农业与生态农业在非洲提升农业韧性与粮食安全的成效及障碍。","文献综述、案例研究与政策框架分析。","两类策略有效但受资金、基建、推广服务及政策偏向制约。","可量化评估CSA与生态农业在非洲不同区域的适配性与政策协同效果。","2026-09-22T23:30:10.505058Z",{"id":284,"title":285,"url":286,"summary":287,"summary_zh":288,"content":9,"source_name":289,"source_url":286,"published_at":290,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":291,"score_detail":292,"sources":294,"tags":296,"primary_topic":300,"secondary_topics":301,"classification":304,"search_phrases":345,"slug":348,"view_count":99,"doi":349,"paper":350,"created_at":367},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":21,"substance":18,"depth":147,"authority":62,"freshness":21,"relevant":22,"comment":293},"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。",[295],{"name":289,"url":286},[27,28,297,298,299],"气候智慧农业","农业推广","津巴布韦",{"code":54,"slug":204,"name":205,"path":206,"parent_code":207},[302,303],{"code":76,"slug":135,"name":136,"path":137,"parent_code":138},{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":305},{"candidates":306,"agricultural_evidence":47},[307,311,315,321,327,334,341],{"code":54,"score":147,"supported":47,"title":308,"abstract":309,"tags":310},[58],[27,58],[27],{"code":76,"score":147,"supported":47,"title":312,"abstract":313,"tags":314},[80],[28,80],[28],{"code":33,"score":13,"supported":47,"title":316,"abstract":317,"tags":320},[],[29,318,49,319],"干旱","drought",[297],{"code":322,"score":55,"supported":47,"title":323,"abstract":324,"tags":326},"G1",[],[298,325],"agricultural extension",[298],{"code":328,"score":62,"supported":47,"title":329,"abstract":330,"tags":333},"A3",[],[331,332],"玉米","maize",[],{"code":335,"score":62,"supported":47,"title":336,"abstract":337,"tags":340},"G3",[],[338,339],"农村金融","rural finance",[],{"code":83,"score":84,"supported":47,"title":342,"abstract":343,"tags":344},[],[87],[],[346,347],"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":349,"openalex_id":351,"authors":352,"venue":289,"cited_by_count":99,"oa_url":9,"card":361,"direction":107,"ingested_from":108},"W7223029383",[353,356,359],{"name":354,"orcid":355},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":357,"orcid":358},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":360,"orcid":9},"Patience Mutopo",{"tldr":362,"method":363,"finding":364,"direction":365,"opportunity":366},"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":369,"title":370,"url":371,"summary":372,"summary_zh":373,"content":9,"source_name":374,"source_url":371,"published_at":375,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":376,"score_detail":377,"sources":379,"tags":381,"primary_topic":385,"secondary_topics":386,"classification":390,"search_phrases":431,"slug":434,"view_count":99,"doi":9,"paper":435,"created_at":449},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":18,"substance":122,"depth":19,"authority":124,"freshness":62,"relevant":22,"comment":378},"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。",[380],{"name":374,"url":371},[382,27,29,383,384],"智慧农业","适应性策略","水资源短缺",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[387],{"code":61,"slug":249,"name":388,"path":389,"parent_code":37},"水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation",{"status":40,"locked":14,"version":41,"method":42,"evidence":391},{"candidates":392,"agricultural_evidence":47},[393,397,401,405,412,416,423,427],{"code":33,"score":18,"supported":47,"title":394,"abstract":395,"tags":396},[49],[29,318,49,319],[29],{"code":61,"score":125,"supported":47,"title":398,"abstract":399,"tags":400},[],[248,65,249],[],{"code":54,"score":55,"supported":47,"title":402,"abstract":403,"tags":404},[],[27,58],[27],{"code":406,"score":62,"supported":47,"title":407,"abstract":408,"tags":411},"A2",[],[409,410],"小麦","wheat",[],{"code":328,"score":62,"supported":47,"title":413,"abstract":414,"tags":415},[],[331,332],[],{"code":417,"score":62,"supported":47,"title":418,"abstract":419,"tags":422},"A6",[],[420,421],"棉花","cotton",[],{"code":83,"score":77,"supported":47,"title":424,"abstract":425,"tags":426},[],[87],[382],{"code":230,"score":84,"supported":47,"title":428,"abstract":429,"tags":430},[],[234],[],[432,433],"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":436,"authors":437,"venue":374,"cited_by_count":99,"oa_url":371,"card":444,"direction":107,"ingested_from":108},"W7222907396",[438,440,442],{"name":439,"orcid":9},"Mohammad Shafiq Faieq",{"name":441,"orcid":9},"Mustafa Abid",{"name":443,"orcid":9},"Abdul khalil Afghani",{"tldr":445,"method":446,"finding":447,"direction":105,"opportunity":448},"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":451,"title":452,"url":453,"summary":454,"summary_zh":455,"content":9,"source_name":456,"source_url":453,"published_at":375,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":457,"score_detail":458,"sources":460,"tags":462,"primary_topic":465,"secondary_topics":466,"classification":469,"search_phrases":531,"slug":534,"view_count":99,"doi":535,"paper":536,"created_at":548},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.

Second-generation econometric methods, robust to cross-sectional dependence and slope heterogeneity, are employed to ensure methodological rigor. Using the Cross-Sectionally Augmented Autoregressive Distributed Lag model alongside panel cointegration tests, the study establishes long-term relationships among the variables of interest. The results reveal that a 1% increase in average annual precipitation (APRE), ATFP, and EPS is associated with long-term increases in food production of 0.15, 0.93, and 0.04%, respectively. In contrast, a 1% rise in average annual temperature (ATP) is found to reduce food production by 0.98% in the long term. Moderation analysis further demonstrates that ATFP significantly moderates the relationship between both APRE and ATP and food production in both the long and short term. EPS, however, exerts a significant moderating effect exclusively on the ATP-food production nexus in the short term. The robustness of the baseline estimates is confirmed through alternative estimation strategies, including Fully Modified Ordinary Least Squares and Dynamic Ordinary Least Squares, as well as the incorporation of alternative control variables. Based on these findings, the study offers actionable policy recommendations for selected emerging economies, emphasizing the enhancement of ATFP and the implementation of stringent environmental regulatory frameworks as critical pathways to ensuring food security in the face of accelerating climate change.","本研究考察了1990—2022年间气候变化、环境政策严格度（EPS）和农业全要素生产率（ATFP）对部分新兴经济体粮食生产的长期影响。为确保方法论的严谨性，本研究采用了对截面依赖性和斜率异质性具有稳健性的第二代计量经济学方法。通过使用截面增强自回归分布滞后模型并结合面板协整检验，本研究确立了所关注变量之间的长期关系。结果表明，年均降水量（APRE）、ATFP和EPS每增加1%，粮食生产在长期内分别增加0.15%、0.93%和0.04%。相比之下，年均气温（ATP）每上升1%，粮食生产在长期内减少0.98%。调节效应分析进一步表明，ATFP在长期和短期内均显著调节APRE和ATP与粮食生产之间的关系。然而，EPS仅在短期内对ATP—粮食生产关系具有显著的调节效应。基准估计结果的稳健性通过替代估计策略得到验证，包括完全修正普通最小二乘法（FMOLS）和动态普通最小二乘法（DOLS），以及纳入替代控制变量。基于上述发现，本研究为部分新兴经济体提出了可操作的政策建议，强调提升ATFP和实施严格的环境监管框架是面对加速气候变化时确保粮食安全的关键路径。","Frontiers in Sustainable Food Systems","2026-10-12T00:00:00Z",80,{"impact":18,"substance":17,"depth":18,"authority":20,"freshness":125,"relevant":22,"comment":559},"基于1990—2022年新兴经济体面板数据的实证研究，量化了气温、降水、环境规制与农业全要素生产率对粮食生产的长期影响，方法严谨、结论具体，对气候适应型农业政策有参考价值。",[561],{"name":555,"url":552},[27,29,563,564,565],"环境规制","农业全要素生产率","新兴经济体",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[],{"status":40,"locked":14,"version":41,"method":42,"evidence":569},{"candidates":570,"agricultural_evidence":47},[571,575],{"code":33,"score":147,"supported":47,"title":572,"abstract":573,"tags":574},[49],[29,49],[29],{"code":54,"score":55,"supported":47,"title":576,"abstract":577,"tags":578},[],[27,58],[27],[580,581],"农业全要素生产率 气候变化 粮食生产","环境政策强度 新兴经济体 粮食安全","农业全要素生产率气候变化粮食生产-4790","10.3389\u002Ffsufs.2026.1925201",{"doi":583,"openalex_id":585,"authors":586,"venue":555,"cited_by_count":99,"oa_url":552,"card":594,"direction":105,"ingested_from":108},"W7221508368",[587,590,592],{"name":588,"orcid":589},"Awais Ahmed Brohi","https:\u002F\u002Forcid.org\u002F0009-0004-4290-9877",{"name":591,"orcid":9},"Waheed Ali",{"name":593,"orcid":9},"Yoshihisa Suzuki",{"tldr":595,"method":596,"finding":597,"direction":105,"opportunity":598},"研究气候变化、环境政策与农业全要素生产率对新兴经济体粮食生产的长期影响。","采用横截面增强自回归分布滞后模型与面板协整检验，基于1990–2022年新兴经济","气温每升1%使粮食产量降0.98%，而农业全要素生产率与环境政策严格度则显著促进粮食生产。","可探究环境政策严格度与农业全要素生产率的协同机制，以及在不同气候情景下的动态阈值效应。","2026-10-13T23:30:06.664953Z"]
