This study examines determinants of adoption of selected CSA practices and their effects on maize productivity, farm income, food expenditure share, and dietary diversity among 510 smallholder households in Kasungu District, central Malawi. Using 2023 cross-sectional survey data, we employ a multinomial endogenous switching regression model to address potential selection bias across eight mutually exclusive adoption options based on three CSA practices. Gender of the household head, extension participation, and cooperative membership are significantly associated with adoption, with female-headed households more likely to adopt multiple-practice combinations. Average treatment effect on the treated (ATT) estimates indicate significant maize-yield and farm-income gains for certain options relative to the estimated non-adoption counterfactual. However, no practice option shows a statistically significant ATT estimate for dietary diversity measured by the Food Consumption Score, indicating a disconnect between estimated farm-income gains and dietary outcomes. The findings suggest that CSA may support productivity and income, but complementary nutrition-sensitive interventions may be needed to achieve multidimensional food security.","气候智能型农业（CSA）被广泛推广以在日益加剧的气候风险下改善小农户生计，然而关于其超越生产力层面影响（尤其是多维粮食安全）的证据仍然有限。本研究考察了马拉维中部卡松古区510户小农户采纳特定CSA实践的决定因素及其对玉米生产力、农场收入、食品支出份额和膳食多样性的影响。利用2023年横截面调查数据，我们采用多项内生转换回归模型，以解决基于三种CSA实践形成的八种互斥采纳选项中的潜在选择偏差。户主性别、推广参与和合作社成员身份与采纳行为显著相关，其中女性户主家庭更倾向于采纳多种实践组合。处理组平均处理效应（ATT）估计表明，相对于估计的非采纳反事实情景，某些选项在玉米产量和农场收入方面具有显著增益。然而，没有任何实践选项在食品消费得分衡量的膳食多样性方面显示出统计显著的ATT估计值，这表明估计的农场收入增益与膳食结果之间存在脱节。研究结果表明，CSA可能有助于提高生产力和收入，但实现多维粮食安全可能需要补充营养敏感型干预措施。",null,"Figshare","2026-09-06T00:00:00Z","论文",40,false,64,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,22,18,10,2,1,"研究揭示CSA增产增收但未改善膳食多样性，对政策制定有参考价值。",[25,26,29],{"name":10,"url":6},{"name":27,"url":28},"Cogent Food & Agriculture","https:\u002F\u002Fdoi.org\u002F10.1080\u002F23311932.2026.2725385",{"name":10,"url":30},"https:\u002F\u002Fdoi.org\u002F10.6084\u002Fm9.figshare.33441414.v1",[32,33,34,35],"非洲","粮食安全","小农户","气候智慧农业",{"code":37,"slug":38,"name":39,"path":40,"parent_code":41},"A8","yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[43],{"code":44,"slug":45,"name":46,"path":47,"parent_code":48},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",{"status":50,"locked":14,"version":51,"method":52,"evidence":53},"classified","2026-10-22.2","rules",{"candidates":54,"agricultural_evidence":57},[55,62,67,74,82],{"code":37,"score":56,"supported":57,"title":58,"abstract":60,"tags":61},15,true,[59],"food security",[33,59],[33],{"code":44,"score":56,"supported":57,"title":63,"abstract":65,"tags":66},[64],"smallholder",[34,64],[34],{"code":68,"score":69,"supported":57,"title":70,"abstract":72,"tags":73},"I1",11,[71],"smart agriculture",[71],[],{"code":75,"score":76,"supported":57,"title":77,"abstract":78,"tags":81},"A3",6,[],[79,80],"玉米","maize",[],{"code":83,"score":22,"supported":14,"title":84,"abstract":85,"tags":86},"H7",[],[],[35],[88,89],"气候智慧农业 粮食安全 小农户 非洲","气候智慧农业 粮食安全","气候智慧农业粮食安全小农户非洲-1825",3,"10.6084\u002Fm9.figshare.33441414",{"doi":92,"openalex_id":94,"authors":95,"venue":10,"cited_by_count":102,"oa_url":6,"card":103,"direction":109,"ingested_from":110},"W7210263968",[96,98,100],{"name":97,"orcid":9},"Jinwon Suh",{"name":99,"orcid":9},"Seongtae Ji",{"name":101,"orcid":9},"Tabitha C.

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":124,"substance":19,"depth":56,"authority":76,"freshness":124,"relevant":22,"comment":125},8,"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。",[127],{"name":120,"url":117},[33,34,35,129,130],"农业推广","津巴布韦",{"code":37,"slug":38,"name":39,"path":40,"parent_code":41},[133,134],{"code":44,"slug":45,"name":46,"path":47,"parent_code":48},{"code":83,"slug":135,"name":136,"path":137,"parent_code":138},"climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",{"status":50,"locked":14,"version":51,"method":52,"evidence":140},{"candidates":141,"agricultural_evidence":57},[142,146,150,158,165,169,176],{"code":37,"score":56,"supported":57,"title":143,"abstract":144,"tags":145},[59],[33,59],[33],{"code":44,"score":56,"supported":57,"title":147,"abstract":148,"tags":149},[64],[34,64],[34],{"code":83,"score":20,"supported":57,"title":151,"abstract":152,"tags":157},[],[153,154,155,156],"气候变化","干旱","climate change","drought",[35],{"code":159,"score":160,"supported":57,"title":161,"abstract":162,"tags":164},"G1",7,[],[129,163],"agricultural extension",[129],{"code":75,"score":76,"supported":57,"title":166,"abstract":167,"tags":168},[],[79,80],[],{"code":170,"score":76,"supported":57,"title":171,"abstract":172,"tags":175},"G3",[],[173,174],"农村金融","rural finance",[],{"code":68,"score":91,"supported":57,"title":177,"abstract":178,"tags":179},[],[71],[],[181,182],"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":184,"openalex_id":186,"authors":187,"venue":120,"cited_by_count":102,"oa_url":9,"card":196,"direction":109,"ingested_from":110},"W7223029383",[188,191,194],{"name":189,"orcid":190},"Casper Myambo","https:\u002F\u002Forcid.org\u002F0009-0007-8625-7526",{"name":192,"orcid":193},"Chipo Plaxedes Mubaya","https:\u002F\u002Forcid.org\u002F0000-0002-4123-0238",{"name":195,"orcid":9},"Patience Mutopo",{"tldr":197,"method":198,"finding":199,"direction":200,"opportunity":201},"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":204,"title":205,"url":206,"summary":207,"summary_zh":208,"content":9,"source_name":209,"source_url":206,"published_at":210,"category":12,"cover_url":9,"hotness":20,"is_selected":14,"score":211,"score_detail":212,"sources":217,"tags":219,"primary_topic":222,"secondary_topics":223,"classification":226,"search_phrases":294,"slug":297,"view_count":102,"doi":298,"paper":299,"created_at":312},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.

However, policy recognition has not been matched by sufficient household-level evidence on the extent and distribution of UIC adoption, the factors associated with adoption, or the relationship between UIC adoption and household food access insecurity among smallholder farming households in South Africa. Methods A quantitative, cross-sectional observational design was used among 205 smallholder farming households in KwaZulu-Natal and the Eastern Cape. Household food-access insecurity was measured using the Household Food Insecurity Access Scale (HFIAS). Logistic regression, ordinary least squares regression, propensity-score matching, chi-square tests, and descriptive analysis were used to examine adoption patterns, associated factors, and food-access security outcomes. Results UIC adoption was reported by 70.2% of respondents, with pumpkin, cowpeas, and amaranth among the most widely cultivated crops. Adopting households had lower mean HFIAS scores than non-adopting households and were less likely to be classified as severely food insecure. In the OLS model, adoption was negatively associated with HFIAS scores ( β = −2.10, p = 0.007). Propensity-score matching also estimated a lower HFIAS score among adopters than among matched non-adopters (ATT = −2.15, p = 0.006). Water sufficiency, group membership, extension contact, education, and household size were associated with food-access security. Discussion The findings indicate that UIC adoption is associated with better household food-access security, but the cross-sectional observational design does not establish a causal effect. Promoting UICs may contribute to nutrition-sensitive agricultural development when accompanied by enabling conditions such as reliable water access, extension support, social capital, and productive resources.","引言 在南非，未被充分利用的本土作物（underutilised indigenous crops, UICs）日益被视为具有韧性和营养敏感性的农业系统的潜在组成部分。然而，政策层面的认可与充分的家庭层面证据之间仍存在差距，这些证据涉及UIC采用的程度与分布、与采用相关的因素，以及UIC采用与南非小农家庭食物获取不安全状况之间的关系。方法 本研究采用定量、横断面观察性设计，在夸祖鲁-纳塔尔省和东开普省的205个小农家庭中开展调查。家庭食物获取不安全状况采用家庭食物不安全获取量表（Household Food Insecurity Access Scale, HFIAS）进行测量。研究运用逻辑回归、普通最小二乘回归、倾向得分匹配、卡方检验和描述性分析，考察采用模式、相关因素及食物获取安全结果。结果 70.2%的受访者报告采用了UIC，其中南瓜、豇豆和苋菜是种植最广泛的作物。采用UIC的家庭HFIAS平均得分低于未采用家庭，且被归类为严重食物不安全的可能性更低。在OLS模型中，采用UIC与HFIAS得分呈负相关（β = −2.10，p = 0.007）。倾向得分匹配也估计出采用者的HFIAS得分低于匹配后的非采用者（ATT = −2.15，p = 0.006）。水资源充足性、群体成员身份、推广接触、教育程度和家庭规模与食物获取安全相关。讨论 研究结果表明，UIC采用与更好的家庭食物获取安全相关，但横断面观察性设计无法确立因果效应。在具备可靠水资源获取、推广支持、社会资本和生产性资源等有利条件的情况下，推广UIC可能有助于营养敏感型农业发展。","Frontiers in Sustainable Food

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":124,"substance":19,"depth":454,"authority":76,"freshness":124,"relevant":22,"comment":455},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。",[457],{"name":120,"url":449},[33,34,35,130],{"code":37,"slug":38,"name":39,"path":40,"parent_code":41},[461],{"code":462,"slug":463,"name":464,"path":465,"parent_code":138},"H8","sustainable-agriculture","可持续与保护性农业","\u002Ftopic\u002Fenvironment\u002Fsustainable-agriculture",{"status":50,"locked":14,"version":51,"method":52,"evidence":467},{"candidates":468,"agricultural_evidence":57},[469,473,478,482,487,491],{"code":37,"score":56,"supported":57,"title":470,"abstract":471,"tags":472},[59],[33,59],[33],{"code":462,"score":124,"supported":57,"title":474,"abstract":476,"tags":477},[475],"conservation agriculture",[],[],{"code":83,"score":160,"supported":57,"title":479,"abstract":480,"tags":481},[],[153,155],[35],{"code":44,"score":483,"supported":57,"title":484,"abstract":485,"tags":486},4,[],[64],[34],{"code":68,"score":91,"supported":57,"title":488,"abstract":489,"tags":490},[],[71],[],{"code":492,"score":91,"supported":57,"title":493,"abstract":494,"tags":496},"I7",[],[495],"研究方法",[],[498,499],"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":501,"openalex_id":503,"authors":504,"venue":120,"cited_by_count":102,"oa_url":9,"card":511,"direction":109,"ingested_from":110},"W7223010488",[505,508],{"name":506,"orcid":507},"Irony Mazuruse","https:\u002F\u002Forcid.org\u002F0009-0007-5600-7825",{"name":509,"orcid":510},"Judith Chokumanyara","https:\u002F\u002Forcid.org\u002F0009-0000-7386-9960",{"tldr":512,"method":513,"finding":514,"direction":310,"opportunity":515},"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":518,"title":519,"url":520,"summary":521,"summary_zh":522,"content":9,"source_name":523,"source_url":520,"published_at":524,"category":12,"cover_url":9,"hotness":20,"is_selected":14,"score":525,"score_detail":526,"sources":528,"tags":530,"primary_topic":533,"secondary_topics":534,"classification":535,"search_phrases":554,"slug":557,"view_count":21,"doi":558,"paper":559,"created_at":578},4883,"Determinants of climate smart agricultural practices adoption and their implications for household food security in Musanze District, Rwanda","https:\u002F\u002Fdoi.org\u002F10.1080\u002F19320248.2026.2739942","Climate change threatens smallholder agriculture in Sub-Saharan Africa.

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":124,"substance":19,"depth":56,"authority":215,"freshness":342,"relevant":22,"comment":527},"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。",[529],{"name":523,"url":520},[33,34,35,531,532],"膳食多样性","卢旺达",{"code":37,"slug":38,"name":39,"path":40,"parent_code":41},[],{"status":50,"locked":14,"version":51,"method":52,"evidence":536},{"candidates":537,"agricultural_evidence":57},[538,542,546,550],{"code":37,"score":56,"supported":57,"title":539,"abstract":540,"tags":541},[59],[33,59],[33],{"code":83,"score":160,"supported":57,"title":543,"abstract":544,"tags":545},[],[153,155],[35],{"code":44,"score":483,"supported":57,"title":547,"abstract":548,"tags":549},[],[64],[34],{"code":68,"score":91,"supported":57,"title":551,"abstract":552,"tags":553},[],[71],[],[555,556],"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":558,"openalex_id":560,"authors":561,"venue":523,"cited_by_count":102,"oa_url":572,"card":573,"direction":109,"ingested_from":110},"W7221514696",[562,564,566,569],{"name":563,"orcid":9},"Chance Bertine Imboni",{"name":565,"orcid":9},"Jonas Nzabamwita",{"name":567,"orcid":568},"Christophe Mupenzi","https:\u002F\u002Forcid.org\u002F0000-0003-1088-4527",{"name":570,"orcid":571},"Thompson Faraday Ediagbonya","https:\u002F\u002Forcid.org\u002F0000-0003-0878-8851","https:\u002F\u002Fdoi.org\u002F10.6084\u002Fm9.figshare.34398567",{"tldr":574,"method":575,"finding":576,"direction":310,"opportunity":577},"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"]
