Gendered roles influence household food priorities, yet little is known about how decision-making dynamics shift under stress and shape dietary coping responses. This study examined the dietary coping strategies employed by households during periods of stress and the role of gendered decision-making in mediating these adaptive responses. Data were collected using a novel Participatory Food Budgeting and Negotiation (PaFBaN) approach, complemented by observations of food purchasing and preparation practices. The study was rural Malawi ( n =24) and peri-urban Zambia ( n =44) enabling comparison across contrasting contexts. Inductive thematic content analysis was applied. Despite contextual differences, households in both settings demonstrated remarkably similar dietary coping strategies under stress. Food choices converged around carbohydrate-based staples, particularly maize, supplemented by inexpensive vegetables and minimal protein sources. The convergence reflected constraint-driven adaptation, with affordability, caloric sufficiency, and availability outweighing preferences, nutritional considerations and food safety concerns. Negotiated lean budgets were more closely aligned with women’s than men’s proposed budgets, suggesting greater women agency in food-related decision-making. Women played a key role in budget negotiations, used their knowledge of food prices, quantities, and meal preparation to refine men’s estimates to agreeable household food plans. Men’s influence became more prominent as resources increased and households incorporated discretionary, status-related, or identity-linked foods, while women continued to prioritise dietary adequacy, continuity, and meal management. The study reframes gendered dietary behaviour under chronic stress as negotiated adaptation, underscoring the need for food security interventions and consumer education that address both material scarcity and intra-household decision regimes.","撒哈拉以南非洲农村及低社会经济城市家庭的食物与营养安全依然脆弱，尤其在季节性短缺和收入波动带来的压力条件下更为突出。性别化角色影响家庭食物优先次序，但人们对压力下决策动态如何变化并塑造饮食应对反应知之甚少。本研究考察了家庭在压力时期采用的饮食应对策略，以及性别化决策在调节这些适应性反应中的作用。数据采用新颖的参与式食物预算与协商（Participatory Food Budgeting and Negotiation, PaFBaN）方法收集，并辅以对食物购买和制备实践的观察。研究地点为马拉维农村（n=24）和赞比亚城郊（n=44），以便在差异显著的情境间进行比较。采用归纳性主题内容分析。尽管存在情境差异，两地家庭在压力下表现出高度相似的饮食应对策略。食物选择趋同于以碳水化合物为基础的主食，尤其是玉米，辅以廉价蔬菜和极少量蛋白质来源。这种趋同反映了约束驱动的适应，可负担性、热量充足性和可获得性压倒了偏好、营养考量和食品安全关切。协商后的紧缩预算与女性提出的预算比男性提出的更为一致，表明女性在食物相关决策中具有更大能动性。女性在预算协商中发挥关键作用，利用其对食物价格、数量和膳食制备的了解来修正男性的估算，以达成双方认可的家庭食物计划。随着资源增加，家庭纳入可自由支配的、与地位或身份相关的食物时，男性的影响变得更为突出，而女性则继续优先考虑膳食充足性、连续性和餐食管理。本研究将长期压力下的性别化饮食行为重新界定为协商性适应，强调食物安全干预和消费者教育需同时应对物质匮乏与家庭内部决策体制。",null,"Frontiers in Sustainable Food Systems","2026-09-25T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究撒哈拉以南非洲家庭性别化食物决策与膳食应对，属营养与性别研究，与三农信息化、智慧农业、数字乡村无直接关联，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23,24,25],"粮食安全","赞比亚","马拉维","性别决策","膳食应对",[27,28],"马拉维 赞比亚 食物预算","性别决策 膳食应对","马拉维赞比亚食物预算-3533","10.3389\u002Ffsufs.2026.1923818",{"doi":30,"openalex_id":32,"authors":33,"venue":10,"cited_by_count":15,"oa_url":6,"card":42,"direction":46,"ingested_from":48},"W7214367169",[34,36,38,40],{"name":35,"orcid":9},"M.

This decline comes amid global increases in hunger and poverty especially in rural communities of developing (Global South) countries. Addressing the systemic issues of hunger and poverty can include the use of more diverse and integrated food production and supply systems that are ecologically sustainable. In sub-Saharan Africa where communities often rely on the harvesting of locally available wild food resources including edible insects, little research has been conducted to understand how entomophagy could help communities achieve food security. This study examines the potential contribution of edible insects to household food security, socioeconomic sustainability and sociocultural cohesion in a rural area of Central Province, Zambia. Data were collected from 139 rural household heads using questionnaires, supported by six focus group discussions with community members. Data were analyzed using descriptive statistics and thematic analysis. Results indicate that entomophagy has the potential to contribute to sustainable food systems through its consideration of local biophysical environmental conditions and resources, and community social and cultural values. However, the study found that there was a lack of integration of edible insect resources into mainstream economic and dietary frameworks, limiting their potential to contribute to sustainable livelihoods, food security and wellbeing.","野生食物资源的利用，尤其是食虫实践（将昆虫作为食物食用），在全球许多社区中已经衰退。这一衰退发生在全球饥饿与贫困加剧的背景下，尤其是在发展中国家（全球南方）的农村社区。解决饥饿与贫困的系统性问题可以包括采用更加多样化和综合化的食物生产与供应体系，这些体系具有生态可持续性。在撒哈拉以南非洲，社区往往依赖采集当地可获得的野生食物资源，包括可食用昆虫，但鲜有研究探讨食虫如何帮助社区实现粮食安全。本研究考察了可食用昆虫在赞比亚中央省某农村地区对家庭粮食安全、社会经济可持续性及社会文化凝聚力的潜在贡献。数据通过问卷从139名农村家庭户主处收集，并以与社区成员进行的六次焦点小组讨论作为辅助。数据采用描述性统计和主题分析进行分析。结果表明，食虫通过考虑当地生物物理环境条件和资源以及社区社会文化价值，具有促进可持续食物体系的潜力。然而，研究发现可食用昆虫资源缺乏被纳入主流经济和饮食框架，限制了其促进可持续生计、粮食安全和福祉的潜力。",62,{"impact":62,"substance":63,"depth":64,"authority":65,"freshness":62,"relevant":52,"comment":66},8,18,15,13,"基于赞比亚农村139户调查的实证研究，揭示食用昆虫未被纳入主流经济与膳食框架，对全球南方食物系统研究有参考价值，但地域性强、公共影响有限。",[68],{"name":10,"url":57},[21,70,22,71,72],"可持续农业","农村生计","食用昆虫",[74,75],"赞比亚 食用昆虫 粮食安全","可持续农业 农村生计 粮食安全 食用昆虫","赞比亚食用昆虫粮食安全-3532","10.3389\u002Ffsufs.2026.1941643",{"doi":77,"openalex_id":79,"authors":80,"venue":10,"cited_by_count":15,"oa_url":57,"card":85,"direction":89,"ingested_from":48},"W7214362702",[81,83],{"name":82,"orcid":9},"John Nyawali",{"name":84,"orcid":9},"Jasper Knight",{"tldr":86,"method":87,"finding":88,"direction":89,"opportunity":90},"研究赞比亚农村食用昆虫对粮食安全、社会经济可持续性和社会文化凝聚力的潜在贡献。","对139个农户问卷调查，辅以6组焦点小组讨论，用描述统计和主题分析。","食用昆虫可促进可持续食物系统，但未融入主流经济和饮食框架，限制其潜力。","农业绿色发展与碳","可探索将食用昆虫纳入农业信息化平台与政策框架，以提升农村粮食安全与生计。","2026-09-26T23:30:07.633189Z",{"id":93,"title":94,"url":95,"summary":96,"summary_zh":9,"content":9,"source_name":97,"source_url":95,"published_at":98,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":99,"score_detail":100,"sources":105,"tags":107,"search_phrases":111,"slug":114,"view_count":52,"doi":115,"paper":116,"created_at":128},2299,"Causal Effects of Climate-Smart Agriculture Adoption on Smallholder Welfare and Food Security in Zambia: Evidence from Endogenous Switching Regression, Double Machine Learning, and Bayesian Estimation","https:\u002F\u002Fdoi.org\u002F10.21203\u002Frs.3.rs-10994635\u002Fv1","Causal Effects of Climate-Smart Agriculture Adoption on Smallholder Welfare and Food Security in Zambia: Evidence from Endogenous Switching Regression, Double Machine Learning, and Bayesian Estimation。Research Square","Research Square","2026-09-11T00:00:00Z",67,{"impact":101,"substance":102,"depth":63,"authority":62,"freshness":103,"relevant":52,"comment":104},12,20,9,"方法组合新颖、结论有实证价值，但研究对象为赞比亚小农户，对国内三农实践的直接参考有限，适合作为国际经验类精选。",[106],{"name":97,"url":95},[21,108,109,110,22],"因果推断","气候智慧农业","小农户生计",[112,113],"气候智慧农业 小农户生计 因果推断 粮食安全","气候智慧农业 小农户生计","气候智慧农业小农户生计因果推断粮食安全-2299","10.21203\u002Frs.3.rs-10994635\u002Fv1",{"doi":115,"openalex_id":117,"authors":118,"venue":97,"cited_by_count":15,"oa_url":95,"card":9,"direction":127,"ingested_from":48},"W7212246566",[119,122,124],{"name":120,"orcid":121},"Evans Kudzai Chinembiri","https:\u002F\u002Forcid.org\u002F0009-0003-7304-0214",{"name":123,"orcid":9},"Munyaradzi Mutenje",{"name":125,"orcid":126},"Nkele D.

Lake Chad, once one of Africa’s largest freshwater bodies, has experienced significant hydrological fluctuations over the past decades. While long-term historical analyses highlight a severe 90% surface area contraction since the 1960s, short-term operational variations over the last decade require precise quantification to inform active transboundary water management strategies. To address this critical gap, this study aims to develop a replicable remote sensing framework using high-resolution satellite data to quantify Lake Chad’s open water and flooded vegetation dynamics from 2017 to 2025, providing evidence-based insights for sustainable water resource management. The methodology encompasses a comprehensive remote sensing analysis of the contemporary surface water extent of Lake Chad using the high-resolution (10-meter) Esri Sentinel-2 Land Use\u002FLand Cover (LULC) time-series dataset. Through a systematic methodology involving image clipping, reclassification, and area calculation, the study tracked changes in open water, flooded vegetation (wetlands), and total lake system extent. Findings reveal a substantial recovery of the lake system, with total area expanding from 5,808.12 km² in 2017 to 11,588.14 km² in 2025, representing an absolute net growth of 5,780.02 km² (99.5% increase). While the lake has not fully recovered to its historic 1960s extent of approximately 25,000 km², it currently exhibits its most water-abundant state since the turn of the 21st century. These findings have significant implications for water resource management, regional food security, and the livelihoods of approximately 50 million people dependent on the Lake Chad basin.","乍得湖是位于非洲中西部尼日利亚、尼日尔、乍得和喀麦隆四国交界处的内陆淡水湖。乍得湖曾是非洲最大的淡水水体之一，过去数十年来经历了显著的水文波动。尽管长期历史分析显示，自20世纪60年代以来其表面积严重萎缩了90%，但近十年来的短期运行变化仍需精确定量，以指导当前活跃的跨境水资源管理策略。为填补这一关键空白，本研究旨在开发一个可复制的遥感框架，利用高分辨率卫星数据量化2017年至2025年乍得湖开阔水域和淹没植被的动态变化，为可持续水资源管理提供循证依据。方法上，本研究采用高分辨率（10米）Esri Sentinel-2土地利用\u002F土地覆盖（LULC）时间序列数据集，对乍得湖当代地表水范围进行了全面的遥感分析。通过图像裁剪、重分类和面积计算等系统方法，研究追踪了开阔水域、淹没植被（湿地）及湖泊系统总范围的变化。研究结果显示，湖泊系统大幅恢复，总面积从2017年的5,808.12平方公里扩展至2025年的11,588.14平方公里，绝对净增长5,780.02平方公里（增幅99.5%）。尽管该湖尚未完全恢复到20世纪60年代约25,000平方公里的历史范围，但目前呈现出21世纪以来水量最丰沛的状态。这些发现对水资源管理、区域粮食安全以及依赖乍得湖流域的约5,000万人的生计具有重大意义。","OpenAlex","2026-09-24T00:00:00Z",79,{"impact":63,"substance":139,"depth":63,"authority":101,"freshness":103,"relevant":52,"comment":140},22,"基于Sentinel-2十年时序数据量化乍得湖水面恢复99.5%，方法可复制、数据翔实，对跨境水资源与区域粮食安全有参考价值，但属非洲区域研究，国内三农关联度有限。",[142],{"name":135,"url":132},[21,144,145,146,147],"水资源管理","遥感监测","湖泊湿地","跨境流域",[149,150],"乍得湖 Sentinel-2 遥感","乍得湖 水域面积 变化","乍得湖Sentinel-2遥感-3557","10.31223\u002Fx5b22z",{"doi":152,"openalex_id":154,"authors":155,"venue":9,"cited_by_count":15,"oa_url":161,"card":162,"direction":166,"ingested_from":48},"W7214164320",[156,159],{"name":157,"orcid":158},"Umar Yusuf","https:\u002F\u002Forcid.org\u002F0009-0008-3703-1069",{"name":160,"orcid":9},"Umar Usman","https:\u002F\u002Feartharxiv.org\u002Frepository\u002Fobject\u002F15133\u002Fdownload\u002F26255\u002F",{"tldr":163,"method":164,"finding":165,"direction":166,"opportunity":167},"基于Sentinel-2土地覆盖数据量化2017-2025年乍得湖地表水面积变化。","使用10米分辨率Esri Sentinel-2 LULC时序数据，经裁剪、重分类","乍得湖总面积从5808增至11588平方公里，净增99.5%，为21世纪以来最丰水状态。","农业遥感与作物表型","可延伸研究乍得湖扩张对流域农业灌溉、湿地生态及跨境水资源管理的影响。","2026-09-26T23:30:31.292812Z",{"id":170,"title":171,"url":172,"summary":173,"summary_zh":174,"content":9,"source_name":175,"source_url":172,"published_at":136,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":176,"score_detail":177,"sources":180,"tags":182,"search_phrases":186,"slug":189,"view_count":15,"doi":190,"paper":191,"created_at":208},3546,"When Winters Fail: How Warming Winters Fuel Pest Resurgence and Threaten Food Security","https:\u002F\u002Fdoi.org\u002F10.1002\u002Fpei3.70216","ABSTRACT The Mediterranean fruit fly ( Ceratitis capitata , Wiedemann; Diptera: Tephritidae), commonly known as the Medfly, re‐emerged in Mazandaran province, northern Iran—home to an estimated 25% of the nation's fruit crops and approximately 80% of its citrus production—following its apparent eradication in 1984, an outcome consistent with several years of pheromone‐trap surveillance without further captures. Its return in 2006 and subsequent spread is consistent with a broader phenomenon we term the erosion of climatic pest barriers: seasonal thermal conditions that have historically suppressed or excluded pest populations, and which appear to be weakening as winters warm. Warming may facilitate Medfly persistence by relaxing overwintering limitation, although reinvasion pressure, host availability, fruit movement, and surveillance and management practices likely also contribute. In Mazandaran, growers report substantial on‐tree citrus losses during heavy infestation years, and pest‐induced fruit wounding may provide infection courts for common postharvest fungal pathogens, compounding losses for smallholder producers. Current management relies heavily on organophosphate insecticides, particularly malathion, whose hazard classification and associated risks are well documented, even though realized exposure‐related risk in practice depends on application conditions. We situate the Mazandaran case within a broader global pattern of climate‐associated pest range expansion and weakened biological control, and argue that resilience‐based alternatives—including the Sterile Insect Technique, entomopathogenic agents, and threshold‐guided digital monitoring, embedded within climate‐smart agriculture frameworks—offer a technically proven, though not yet regionally established, pathway forward. We propose that climatic pest barriers merit recognition as an ecosystem service whose erosion under warming carries implications for temperate agricultural systems beyond this case.","地中海实蝇（Ceratitis capitata，Wiedemann；双翅目：实蝇科），俗称地中海果蝇，在1984年明显被根除后，重新出现在伊朗北部的马赞德兰省——该省估计占全国水果作物的25%和柑橘产量的约80%——这一根除结果与多年信息素诱捕监测未再捕获到该虫的情况一致。其2006年的重现及随后的扩散，与我们所称的“气候性有害生物屏障侵蚀”这一更广泛现象相符：历史上抑制或排除有害生物种群的季节性热条件，似乎正随着冬季变暖而减弱。气候变暖可能通过放宽越冬限制而促进地中海实蝇的存续，尽管再入侵压力、寄主可获得性、水果调运以及监测和管理实践也可能起作用。在马赞德兰，种植者报告在严重侵染年份柑橘树上果实损失巨大，且有害生物造成的果实伤口可能为常见的采后真菌病原体提供侵染位点，加剧了小农户的损失。当前的管理严重依赖有机磷杀虫剂，尤其是马拉硫磷，其危害分类及相关风险已有充分记录，尽管实际中与暴露相关的现实风险取决于施药条件。我们将马赞德兰的案例置于气候相关的有害生物分布区扩张和生物防治减弱的更广泛全球格局中，并认为基于韧性的替代方案——包括昆虫不育技术、昆虫病原制剂和阈值引导的数字监测，嵌入气候智慧型农业框架内——提供了一条技术上经过验证但尚未在区域内建立的可行路径。我们提出，气候性有害生物屏障值得被认定为一种生态系统服务，其在变暖下的侵蚀对温带农业系统的影响超越了本案例。","Plant-Environment Interactions",78,{"impact":63,"substance":178,"depth":63,"authority":65,"freshness":62,"relevant":52,"comment":179},21,"以伊朗马赞德兰地中海实蝇复现为案例，提出气候性害虫屏障退化概念，并给出昆虫不育技术、数字化阈值监测等气候智慧农业路径，对暖冬区农业植保与粮食安全具参考价值。",[181],{"name":175,"url":172},[183,21,109,184,185],"智慧农业","柑橘产业","害虫监测",[187,188],"地中海实蝇 马赞德兰 柑橘","气候变暖 害虫越冬 粮食安全","地中海实蝇马赞德兰柑橘-3546","10.1002\u002Fpei3.70216",{"doi":190,"openalex_id":192,"authors":193,"venue":175,"cited_by_count":15,"oa_url":172,"card":203,"direction":127,"ingested_from":48},"W7214309725",[194,197,199,201],{"name":195,"orcid":196},"Mostafa Farajpour","https:\u002F\u002Forcid.org\u002F0000-0003-4223-502X",{"name":198,"orcid":9},"Shahab Mirinejad",{"name":200,"orcid":9},"Mitra Moezipour",{"name":202,"orcid":9},"Mohammad Sadat‐Hosseini",{"tldr":204,"method":205,"finding":206,"direction":89,"opportunity":207},"以伊朗马赞德兰省地中海实蝇重现为例，提出气候害虫屏障侵蚀概念，探讨暖冬致害虫复苏威胁粮食安全。","结合害虫监测历史、农户损失报告与文献综述，分析暖冬对越冬限制的放松。","暖冬削弱气候害虫屏障，使地中海实蝇重新定殖并扩散，威胁柑橘等作物生产与粮食安全。","可量化气候害虫屏障作为生态系统服务的价值，并开发阈值引导的数字监测与气候智慧型害虫管理方案。","2026-09-26T23:30:12.754871Z",{"id":210,"title":211,"url":212,"summary":213,"summary_zh":214,"content":9,"source_name":215,"source_url":212,"published_at":11,"category":12,"cover_url":9,"hotness":13,"is_selected":216,"score":217,"score_detail":218,"sources":222,"tags":224,"search_phrases":228,"slug":231,"view_count":15,"doi":232,"paper":233,"created_at":250},3542,"Drought vulnerability assessment and its severe impact on crop production and livelihood of people: An empirical modelling of northern Ghana","https:\u002F\u002Fdoi.org\u002F10.1371\u002Fjournal.pclm.0001038","Climate change is intensifying drought vulnerability in northern Ghana, posing serious risks to crop production, food security, and rural livelihoods in semi-arid regions. This study develops an empirical modelling framework to assess drought vulnerability and impacts at three temporal horizons, 2026–2050, 2051–2075, and 2076–2100, under SSP1-2.6 and SSP5-8.5 scenarios. We integrated bias-corrected outputs from five CMIP6 models, MRI-ESM2–0, EC-Earth3, IPSL-CM6A-LR, CESM2, and HadGEM3-GC31-LL, downscaled to 0.25° resolution, with drought indices including the Standardized Precipitation Index SPI, Reconnaissance Drought Index RDI, Normalized Difference Drought Index NDDI, and Soil Moisture Index SMI. These were combined with MODIS-derived Normalized Difference Vegetation Index NDVI, population density, and land use\u002Fland cover using GIS-based tools to generate composite drought vulnerability maps. CMIP6 models were validated against reference datasets and showed strong performance for annual precipitation, r = 0.95, RMSE = 3.4 mm, and temperature, r = 0.99, RMSE = 0.47–0.74°C. Results project increasing drought severity, with mean temperature rises of 2.0–3.9°C and rainfall declines up to 19% by 2100. Crop yields for maize, millet, sorghum, and groundnuts are expected to fall by 25–60% by 2050, with maize showing the strongest negative correlation to drought severity, r = –0.72, p \u003C 0.01, confirmed by Mann-Kendall trends at the 95% confidence level. About 84% of the study area is classified as highly vulnerable due to limited adaptive capacity, over 80% dependence on rain-fed agriculture, more than 49% household food insecurity, less than 23% cropland use, and under 5% water body coverage. Significant uncertainties remain in precipitation projections, with some models showing divergent temperature trends, highlighting challenges in modelling climate impacts. The findings underscore the urgent need for district-level drought preparedness, solar-powered irrigation, index insurance, climate-smart agriculture, and Disaster Risk Reduction aligned with UNDRR and Sendai Framework priorities to build resilience in northern Ghana.","气候变化正在加剧加纳北部的干旱脆弱性，对半干旱地区的作物生产、粮食安全和农村生计构成严重风险。本研究构建了一个经验建模框架，用于评估2026—2050年、2051—2075年和2076—2100年三个时间尺度下SSP1-2.6和SSP5-8.5情景中的干旱脆弱性及其影响。我们将五个CMIP6模型（MRI-ESM2–0、EC-Earth3、IPSL-CM6A-LR、CESM2和HadGEM3-GC31-LL）的偏差校正输出降尺度至0.25°分辨率，并与标准化降水指数（SPI）、侦察干旱指数（RDI）、归一化差值干旱指数（NDDI）和土壤水分指数（SMI）等干旱指数相结合。这些数据与MODIS衍生的归一化差值植被指数（NDVI）、人口密度以及土地利用\u002F土地覆盖数据通过基于GIS的工具相结合，生成综合干旱脆弱性地图。CMIP6模型经参考数据集验证，在年降水量（r = 0.95，RMSE = 3.4 mm）和温度（r = 0.99，RMSE = 0.47–0.74°C）方面表现出色。结果预测干旱严重程度将加剧，到2100年平均气温上升2.0–3.9°C，降雨量下降高达19%。到2050年，玉米、小米、高粱和花生的作物产量预计将下降25–60%，其中玉米与干旱严重程度呈最强负相关（r = –0.72，p \u003C 0.01），并经Mann-Kendall趋势检验在95%置信水平上得到证实。约84%的研究区域被归类为高度脆弱，原因包括适应能力有限、超过80%依赖雨养农业、超过49%的家庭粮食不安全、不足23%的耕地利用率以及低于5%的水体覆盖率。降水预测仍存在显著不确定性，部分模型显示出不同的温度趋势，凸显了气候影响建模的挑战。研究结果强调迫切需要开展县级干旱备灾、太阳能灌溉、指数保险、气候智慧型农业以及与UNDRR和仙台框架优先事项一致的风险减灾工作，以增强加纳北部的韧性。","PLOS Climate",true,82,{"impact":63,"substance":219,"depth":63,"authority":220,"freshness":103,"relevant":52,"comment":221},23,14,"基于CMIP6多模型与遥感指数的干旱脆弱性实证研究，数据扎实、结论明确，对半干旱区农业防灾与气候适应有参考价值。",[223],{"name":215,"url":212},[21,225,226,145,227],"防灾减灾","气候变化","干旱风险",[229,230],"加纳北部 干旱 玉米","CMIP6 干旱脆弱性 作物产量","加纳北部干旱玉米-3542","10.1371\u002Fjournal.pclm.0001038",{"doi":232,"openalex_id":234,"authors":235,"venue":215,"cited_by_count":15,"oa_url":212,"card":245,"direction":127,"ingested_from":48},"W7214399028",[236,239,242],{"name":237,"orcid":238},"Theophilus Francis Kofitio","https:\u002F\u002Forcid.org\u002F0009-0000-7147-6581",{"name":240,"orcid":241},"Peace Korshiwor Amoatey","https:\u002F\u002Forcid.org\u002F0000-0002-2794-9721",{"name":243,"orcid":244},"Evans Asenso","https:\u002F\u002Forcid.org\u002F0000-0003-3116-6356",{"tldr":246,"method":247,"finding":248,"direction":166,"opportunity":249},"构建干旱脆弱性经验模型，评估加纳北部未来气候情景下作物与生计影响。","集成5个CMIP6模型、SPI\u002FRDI\u002FNDDI\u002FSMI指数与MODIS NDV","至2100年升温2.0-3.9°C、降水降19%，2050年作物减产25-60%，84%区域高度脆弱","可结合遥感干旱指数与作物模型，在数据稀缺区开展多情景脆弱性动态评估与适应策略优化。","2026-09-26T23:30:10.153994Z",{"id":252,"title":253,"url":254,"summary":255,"summary_zh":256,"content":9,"source_name":10,"source_url":254,"published_at":11,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":176,"score_detail":257,"sources":260,"tags":262,"search_phrases":266,"slug":269,"view_count":15,"doi":270,"paper":271,"created_at":287},3534,"From river health to sustainable irrigation water resources: a five-year integrated ecological assessment for climate-resilient food systems in semi-arid Iraq","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1968827","Freshwater degradation in semi-arid regions can simultaneously affect river ecological condition and the reliability of water resources for irrigated food production. This study integrated ecological, irrigation-water, hydroclimatic, and crop-specific assessments across the Euphrates, Shatt Al-Hillah, and Al-Diwaniyah river systems in central Iraq over 5 years (2020–2024). Fifteen stations were monitored seasonally, generating 300 station-season observations. Physicochemical variables, major ions, nutrients, irrigation-water indicators, benthic diatoms, macroinvertebrates, habitat condition, hydroclimatic variables, and crop-specific irrigation constraints were evaluated within a common analytical framework. A persistent spatial gradient was observed across the three river systems. Mean electrical conductivity increased from 855.4 ± 226.3 μS cm −1 in the Euphrates to 1295.5 ± 247.1 μS cm −1 in Shatt Al-Hillah and 1791.9 ± 375.4 μS cm −1 in Al-Diwaniyah, accompanied by increasing Na + , Cl − , nutrients, and irrigation-water restrictions. Overall, 90.3% of observations exhibited slight-to-moderate salinity restriction, whereas severe salinity occurred only in Al-Diwaniyah. Hydroclimatic variability was associated with temporal salinity risk, with the strongest EC anomalies occurring during the summers of 2022 and 2024 and significant negative associations between EC and both SPEI-3 and SPEI-6. Biological condition declined along the same gradient: diatom and macroinvertebrate diversity, EPT representation, habitat condition, and dissolved oxygen were highest in the Euphrates and lowest in Al-Diwaniyah. Principal component analysis explained 89.67% of total variance on the first two axes and clearly contrasted biological condition with salinity, ionic enrichment, and nutrient concentrations. Crop-specific assessment further showed increasing agricultural constraints, with maize being the most sensitive crop and constrained in 100% of observations at all Al-Diwaniyah stations. These findings demonstrate that river ecological condition, irrigation-water reliability, hydroclimatic variability, and crop-specific suitability are closely interconnected. Integrating these dimensions can support more adaptive water allocation and climate-resilient irrigation management in semi-arid food-production systems.","半干旱地区的淡水退化会同时影响河流生态状况与灌溉粮食生产的水资源可靠性。本研究在伊拉克中部的幼发拉底河、希拉河和迪瓦尼耶河三个河系开展了为期5年（2020—2024年）的生态、灌溉用水、水文气候和作物特异性评估的综合研究。研究对15个站点进行季节性监测，共获得300个站点-季节观测数据。在统一的分析框架内，评估了理化变量、主要离子、营养盐、灌溉水指标、底栖硅藻、大型无脊椎动物、栖息地状况、水文气候变量以及作物特异性灌溉限制。三个河系之间呈现出持续的空间梯度。平均电导率从幼发拉底河的855.4 ± 226.3 μS cm⁻¹升至希拉河的1295.5 ± 247.1 μS cm⁻¹和迪瓦尼耶河的1791.9 ± 375.4 μS cm⁻¹，同时伴随Na⁺、Cl⁻、营养盐的增加及灌溉用水限制的加剧。总体而言，90.3%的观测表现为轻度至中度盐度限制，而严重盐度仅出现在迪瓦尼耶河。水文气候变率与盐度的时间风险相关，最强的电导率异常出现在2022年和2024年夏季，且电导率与SPEI-3和SPEI-6均呈显著负相关。生物状况沿同一梯度下降：硅藻和大型无脊椎动物多样性、EPT（蜉蝣目-襀翅目-毛翅目）代表性、栖息地状况和溶解氧在幼发拉底河最高，在迪瓦尼耶河最低。主成分分析在前两个轴上解释了89.67%的总方差，清晰地将生物状况与盐度、离子富集和营养盐浓度形成对比。作物特异性评估进一步表明农业限制日益加剧，其中玉米是最敏感的作物，在迪瓦尼耶河所有站点的100%观测中均受到限制。这些发现表明，河流生态状况、灌溉水可靠性、水文气候变率和作物特异性适宜性密切相关。整合这些维度可支持半干旱粮食生产系统中更具适应性的水资源分配和气候韧性灌溉管理。",{"impact":258,"substance":139,"depth":63,"authority":65,"freshness":103,"relevant":52,"comment":259},16,"五年跨三河水生态与灌溉水质综合评估，数据规模大、结论可靠，对半干旱区气候韧性灌溉管理有参考价值。",[261],{"name":10,"url":254},[21,263,144,264,265],"气候韧性","盐渍化","灌溉水质",[267,268],"伊拉克 幼发拉底河 灌溉水质","半干旱区 盐渍化 灌溉水","伊拉克幼发拉底河灌溉水质-3534","10.3389\u002Ffsufs.2026.1968827",{"doi":270,"openalex_id":272,"authors":273,"venue":10,"cited_by_count":15,"oa_url":254,"card":282,"direction":89,"ingested_from":48},"W7214391385",[274,277,279],{"name":275,"orcid":276},"Bassam M.
