Exploring smallholder farmers’ lived experiences of fall armyworm impacts on hybrid and local maize in Kenya","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1925312","Fall Armyworm (FAW) is a persistent threat to maize-based food systems in sub-Saharan Africa, but less is known about how farmers experience its effects across seed types and household livelihoods. This exploratory qualitative study examined smallholder farmers’ lived experiences of FAW damage in hybrid and local maize in Siaya County, Kenya. Face-to-face semi-structured interviews lasting 30–45 min were conducted with 88 purposively selected farmers, and responses were analyzed thematically by two independent researchers. Farmers described FAW as recurrent and difficult to control; 43.2% reported infestation every season. Most participants (77.3%) perceived hybrid maize as more severely affected than local maize, whereas 9.1% perceived local maize as more affected and 9.1% reported similar effects. Participants associated infestation with reduced yields, impaired crop growth, lower-quality harvests, lost income, pesticide and labour costs, depleted maize stocks, food purchases, and stress related to financial and food uncertainty. Reported responses included pesticide use, repeated spraying, purchasing food, crop diversification, and reconsidering maize varieties. Because the study relied on farmers’ accounts rather than controlled varietal comparisons, the perceived differences cannot be attributed to seed characteristics independently of management and growing conditions. The findings indicate that farmers evaluate FAW damage through interconnected production, livelihood, food-security, and seed-choice concerns, supporting locally tested pest-management and seed advisory services.","草地贪夜蛾（Fall Armyworm, FAW）是撒哈拉以南非洲以玉米为基础的粮食系统面临的持续威胁，但人们对农民在不同种子类型和家庭生计条件下如何经历其影响知之甚少。本探索性定性研究考察了肯尼亚西亚亚县小农户在杂交玉米和本地玉米中遭受草地贪夜蛾危害的生活体验。研究对88名有意选取的农民进行了为期30至45分钟的面对面半结构化访谈，并由两名独立研究人员对回答进行主题分析。农民将草地贪夜蛾描述为反复发生且难以控制；43.2%报告每季均发生虫害。大多数参与者（77.3%）认为杂交玉米比本地玉米受害更严重，而9.1%认为本地玉米受害更严重，9.1%报告两者影响相似。参与者将虫害与产量下降、作物生长受损、收成品质量降低、收入损失、农药和劳动力成本、玉米库存耗尽、粮食购买以及与经济和粮食不确定性相关的压力联系起来。报告的应对措施包括使用农药、反复喷药、购买粮食、作物多样化以及重新考虑玉米品种。由于本研究依赖农民叙述而非受控品种比较，所感知的差异不能独立于管理和生长条件而归因于种子特征。研究结果表明，农民通过生产、生计、粮食安全和种子选择等相互关联的关注来评估草地贪夜蛾危害，这支持开展本地化测试的害虫管理和种子咨询服务。",null,"Frontiers in Sustainable Food Systems","2026-10-02T00:00:00Z","论文",10,false,65,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":13,"relevant":21,"comment":22},8,18,16,13,1,"基于88户肯尼亚小农户访谈的质性研究，揭示草地贪夜蛾对杂交与本地玉米影响的农户感知差异，对非洲玉米病虫害防控与种子推广有参考价值，但属区域案例、公共影响有限。",[24],{"name":10,"url":6},[26,27,28,29,30],"种业振兴","粮食安全","玉米","小农户","病虫害防治",{"code":32,"slug":33,"name":28,"path":34,"parent_code":35},"A3","maize","\u002Ftopic\u002Ffield-crops\u002Fmaize","A",[37],{"code":38,"slug":39,"name":40,"path":41,"parent_code":42},"G2","farm-services","社会化服务与规模经营","\u002Ftopic\u002Frural-services\u002Ffarm-services","G",{"status":44,"locked":14,"version":45,"method":46,"evidence":47},"classified","2026-10-22.2","rules",{"candidates":48,"agricultural_evidence":51},[49,55,60,68,74],{"code":32,"score":50,"supported":51,"title":52,"abstract":53,"tags":54},15,true,[33],[28,33],[28],{"code":38,"score":50,"supported":51,"title":56,"abstract":58,"tags":59},[57],"smallholder",[29,57],[29],{"code":61,"score":62,"supported":51,"title":63,"abstract":64,"tags":67},"F4",6,[],[65,66],"农药","pesticide",[],{"code":69,"score":70,"supported":51,"title":71,"abstract":72,"tags":73},"A8",4,[],[27],[27],{"code":75,"score":21,"supported":14,"title":76,"abstract":77,"tags":78},"F1",[],[],[26],[80,81],"肯尼亚 草地贪夜蛾 玉米","杂交玉米 本地玉米 虫害","肯尼亚草地贪夜蛾玉米-3989",3,"10.3389\u002Ffsufs.2026.1925312",{"doi":84,"openalex_id":86,"authors":87,"venue":10,"cited_by_count":98,"oa_url":6,"card":99,"direction":103,"ingested_from":105},"W7215042180",[88,91,93,95],{"name":89,"orcid":90},"George Ariya","https:\u002F\u002Forcid.org\u002F0000-0003-2286-9455",{"name":92,"orcid":9},"Beatrice Cheserek",{"name":94,"orcid":9},"Violet Kadenyeka Mugalavai",{"name":96,"orcid":97},"Lizzy A.

The study used descriptive statistics to summarize the data, and a logistic regression model on a sample of 1,592 to evaluate the determinants of soil testing among farmers. Descriptive statistics show that less than 8% of farmers had conducted soil tests on their farms, and about 7% knew where to obtain soil testing services. The logistic results show that access to extension services ( p \u003C 0.01), age of the household head ( p \u003C 0.01), group membership ( p \u003C 0.01), farmers’ awareness about where to obtain soil testing services ( p \u003C 0.05), land size ( p \u003C 0.05), perceived fertility of the soil ( p \u003C 0.05), economically active household members ( p \u003C 0.10) are statistically significant in influencing the decision to conduct soil testing.

Standard multi-class classifiers optimize global accuracy but provide no mechanism to operationalize or control this asymmetric cost structure at inference time. We propose CascadeCropNet, a two-stage cascade architecture calibrated to satisfy a target recall constraint (Rec-Damaged >= 0.95) through threshold selection. A lightweight Sentinel model performs binary health triage; samples exceeding a calibrated damage probability threshold tau are escalated to a specialist Expert model for fine-grained diagnosis. This design provides explicit, deployment-time control over the safety-efficiency trade-off without retraining. Evaluated on the Eyes on the Ground dataset (23,804 images from Kenyan smallholder maize farms), the cascade achieves Rec-Damaged = 0.974 at tau = 0.5, reducing missed damage cases by up to 54% relative to a flat baseline. Under evaluation alignment, the representational gap reduces to +0.008 F1-macro, confirming the contribution is architectural rather than representational. Under input degradation, the system prioritizes escalation over confident misclassification, reflecting error containment through architectural isolation rather than intrinsic model robustness. These results demonstrate that cascade architectures can operationalize safety-oriented decision constraints through calibrated routing in settings where reliability matters more than aggregate accuracy. These properties depend on threshold calibration and deployment conditions and do not constitute guarantees under arbitrary distribution shift.\n\nComments:44 pages, 7 figures, 12 tables.

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

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.
