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。",null,"OpenAlex","2026-09-24T00:00:00Z","论文",10,false,79,{"impact":17,"substance":18,"depth":17,"authority":19,"freshness":20,"relevant":21,"comment":22},18,22,12,9,1,"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。",[24],{"name":10,"url":6},[26,27,28,29,30],"粮食安全","水资源管理","遥感监测","湖泊湿地","跨境流域",[32,33],"乍得湖 Sentinel-2 遥感","乍得湖 水域面积 变化","乍得湖Sentinel-2遥感-3557",0,"10.31223\u002Fx5b22z",{"doi":36,"openalex_id":38,"authors":39,"venue":9,"cited_by_count":35,"oa_url":45,"card":46,"direction":50,"ingested_from":52},"W7214164320",[40,43],{"name":41,"orcid":42},"Umar Yusuf","https:\u002F\u002Forcid.org\u002F0009-0008-3703-1069",{"name":44,"orcid":9},"Umar Usman","https:\u002F\u002Feartharxiv.org\u002Frepository\u002Fobject\u002F15133\u002Fdownload\u002F26255\u002F",{"tldr":47,"method":48,"finding":49,"direction":50,"opportunity":51},"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。","openalex","2026-09-26T23:30:31.292812Z",{"total":55,"page":21,"page_size":55,"items":56},6,[57,101,142,182,233,271],{"id":58,"title":59,"url":60,"summary":61,"summary_zh":62,"content":9,"source_name":63,"source_url":60,"published_at":64,"category":12,"cover_url":9,"hotness":13,"is_selected":65,"score":66,"score_detail":67,"sources":71,"tags":73,"search_phrases":77,"slug":80,"view_count":35,"doi":81,"paper":82,"created_at":100},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","2026-09-25T00:00:00Z",true,82,{"impact":17,"substance":68,"depth":17,"authority":69,"freshness":20,"relevant":21,"comment":70},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。",[72],{"name":63,"url":60},[26,74,75,28,76],"防灾减灾","气候变化","干旱风险",[78,79],"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":81,"openalex_id":83,"authors":84,"venue":63,"cited_by_count":35,"oa_url":60,"card":94,"direction":99,"ingested_from":52},"W7214399028",[85,88,91],{"name":86,"orcid":87},"Theophilus Francis Kofitio","https:\u002F\u002Forcid.org\u002F0009-0000-7147-6581",{"name":89,"orcid":90},"Peace Korshiwor Amoatey","https:\u002F\u002Forcid.org\u002F0000-0002-2794-9721",{"name":92,"orcid":93},"Evans Asenso","https:\u002F\u002Forcid.org\u002F0000-0003-3116-6356",{"tldr":95,"method":96,"finding":97,"direction":50,"opportunity":98},"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。","智慧农业 \u002F 农业物联网","2026-09-26T23:30:10.153994Z",{"id":102,"title":103,"url":104,"summary":105,"summary_zh":106,"content":9,"source_name":107,"source_url":104,"published_at":64,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":108,"score_detail":109,"sources":113,"tags":115,"search_phrases":119,"slug":122,"view_count":35,"doi":123,"paper":124,"created_at":141},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。","Frontiers in Sustainable Food Systems",78,{"impact":110,"substance":18,"depth":17,"authority":111,"freshness":20,"relevant":21,"comment":112},16,13,"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。",[114],{"name":107,"url":104},[26,116,27,117,118],"气候韧性","盐渍化","灌溉水质",[120,121],"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":123,"openalex_id":125,"authors":126,"venue":107,"cited_by_count":35,"oa_url":104,"card":135,"direction":139,"ingested_from":52},"W7214391385",[127,130,132],{"name":128,"orcid":129},"Bassam M.

This study aimed to analyze land use and occupation dynamics from 2002 to 2022 in the Pajeú River basin in Pernambuco, Brazil, and their relationship with drought events, using indices based on remote sensing. The Standardized Precipitation Index (SPI) was applied to characterize meteorological drought, while the Vegetation Health Index (VHI) and Normalized Vegetation Water Supply Index (NVSWI) were used to assess the ecosystem's response. The results indicated that the period from 2011 to 2016 was the most severe and prolonged drought, which was reinforced by low VHI and NVSWI values, indicating water stress on vegetation during the same period. The correlation analysis revealed that land use classes, such as vegetation and water, responded directly to drought, whereas degraded anthropogenic areas, including pasture and exposed soil, exhibited the opposite behavior. The joint analysis of the three indices and land use and occupation data provided a comprehensive understanding of the evolution of drought in the study area, highlighting the importance of a multiple approach to monitoring complex environments.","监测半干旱东北部地区的干旱是一项挑战，降雨变率大且原位监测网络稀缺使这一挑战更加复杂，因此利用地理技术进行水资源管理至关重要。本研究旨在利用基于遥感的指数，分析2002年至2022年巴西伯南布哥州帕热乌河流域的土地利用与覆盖动态及其与干旱事件的关系。采用标准化降水指数（SPI）表征气象干旱，同时使用植被健康指数（VHI）和归一化植被供水指数（NVSWI）评估生态系统的响应。结果表明，2011年至2016年是最严重且持续时间最长的干旱期，同期较低的VHI和NVSWI值进一步证实了这一点，表明植被在此期间受到水分胁迫。相关性分析显示，植被和水体等土地利用类别对干旱有直接响应，而牧场和裸露土壤等退化的人为区域则表现出相反的行为。三个指数与土地利用及覆盖数据的联合分析为理解研究区域干旱演变提供了全面的认识，凸显了多方法途径在监测复杂环境中的重要性。","Journal of Hyperspectral Remote Sensing","2026-09-19T00:00:00Z",61,{"impact":192,"substance":17,"depth":193,"authority":19,"freshness":192,"relevant":21,"comment":194},8,15,"该研究利用遥感指数分析巴西半干旱流域干旱与植被动态，方法扎实但属区域性案例，对国内三农信息化参考价值有限。",[196],{"name":188,"url":185},[27,28,198,199,200],"土地利用","干旱监测","植被指数",[202,203],"Pajeú River basin 干旱 遥感","SPI VHI NVSWI 植被","PajeúRiverbasin干旱遥感-3189","10.29150\u002Fjhrs.v16i03.269030",{"doi":205,"openalex_id":207,"authors":208,"venue":188,"cited_by_count":35,"oa_url":226,"card":227,"direction":50,"ingested_from":52},"W7213792298",[209,212,215,218,221,223],{"name":210,"orcid":211},"Juliana Farias Santos de Moraes","https:\u002F\u002Forcid.org\u002F0000-0002-3241-844X",{"name":213,"orcid":214},"Estephania Silva Jovino","https:\u002F\u002Forcid.org\u002F0000-0002-6694-3533",{"name":216,"orcid":217},"Alex Vinícius de Melo Vieira","https:\u002F\u002Forcid.org\u002F0009-0002-5204-3734",{"name":219,"orcid":220},"Anderson Luiz Ribeiro de Paiva","https:\u002F\u002Forcid.org\u002F0000-0003-3475-1454",{"name":222,"orcid":9},"Sylvana Sylvana Melo dos Santos",{"name":224,"orcid":225},"Leidjane Maria Maciel de Oliveira","https:\u002F\u002Forcid.org\u002F0000-0003-1251-6998","https:\u002F\u002Fperiodicos.ufpe.br\u002Frevistas\u002Fjhrs\u002Farticle\u002Fdownload\u002F269030\u002F52814",{"tldr":228,"method":229,"finding":230,"direction":50,"opportunity":231},"利用遥感指数分析巴西Pajeú河流域2002-2022年干旱对植被与土地利用的影响。","采用SPI、VHI和NVSWI指数，结合遥感数据与土地利用分类。","2011-2016年干旱最严重，植被和水体响应直接，而牧场和裸地呈相反趋势。","可融合多源遥感与机器学习，构建半干旱区干旱-植被-土地利用耦合预警模型。","2026-09-22T23:30:26.557816Z",{"id":234,"title":235,"url":236,"summary":237,"summary_zh":238,"content":9,"source_name":239,"source_url":236,"published_at":240,"category":12,"cover_url":9,"hotness":241,"is_selected":14,"score":242,"score_detail":243,"sources":245,"tags":249,"search_phrases":253,"slug":256,"view_count":35,"doi":257,"paper":258,"created_at":270},3171,"WATER RESOURCES – AN IMPORTANT FACTOR IN HUMAN LIFE AND SUSTAINABLE DEVELOPMENT","https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.22882203","This thesis discusses the importance of water resources for human life, agriculture, industry and environmental sustainability.

Under the conditions of Uzbekistan, drip and sprinkler irrigation, modernization of irrigation canals, automated water accounting, remote sensing and geographic information systems can contribute significantly to improving the efficiency and sustainability of water resources management.","本论文探讨了水资源对人类生活、农业、工业及环境可持续性的重要意义。当今，气候变化、人口增长、城市化以及各经济部门用水需求的不断增加，使水资源的合理高效利用成为日益重要的议题。在中亚地区，尤其是乌兹别克斯坦，水资源可利用量有限，亟需提高灌溉效率、减少水量损失并推广现代节水技术。本研究考察了水资源利用的主要领域、水质保护、农业节水、废水回用、地下水保护以及数字技术在水管理中的应用。在乌兹别克斯坦的条件下，滴灌与喷灌、灌溉渠道现代化改造、自动化水量核算、遥感与地理信息系统可显著提升水资源管理的效率与可持续性。","Zenodo (CERN European Organization for Nuclear Research)","2026-09-21T00:00:00Z",25,60,{"impact":19,"substance":110,"depth":69,"authority":13,"freshness":192,"relevant":21,"comment":244},"聚焦乌兹别克斯坦水资源与数字灌溉技术，属农业信息化范畴，但为区域性综述论文，公共影响与信源权威度一般。",[246,247],{"name":239,"url":236},{"name":239,"url":248},"https:\u002F\u002Fdoi.org\u002F10.5281\u002Fzenodo.22882204",[250,251,27,28,252],"数字农业","节水灌溉","中亚农业",[254,255],"乌兹别克斯坦 节水灌溉","遥感 GIS 水资源管理","乌兹别克斯坦节水灌溉-3171","10.5281\u002Fzenodo.22882203",{"doi":257,"openalex_id":259,"authors":260,"venue":239,"cited_by_count":35,"oa_url":236,"card":265,"direction":50,"ingested_from":52},"W7213866152",[261,263],{"name":262,"orcid":9},"ERGASHALIYEV MUXAMMADAZIZ",{"name":264,"orcid":9},"G'aniyev Samandar",{"tldr":266,"method":267,"finding":268,"direction":139,"opportunity":269},"探讨水资源对人类生活与可持续发展的重要性，并以乌兹别克斯坦为例分析节水灌溉与数字化管理。","文献综述与案例分析，涉及滴灌、喷灌、遥感、GIS和自动化水核算。","在乌兹别克斯坦，滴灌、渠道现代化、遥感与GIS可显著提升水资源管理效率与可持续性。","可结合遥感与物联网，量化中亚干旱区节水灌溉对作物产量与碳排放的协同效应。","2026-09-22T23:30:23.028018Z",{"id":272,"title":273,"url":274,"summary":275,"summary_zh":276,"content":9,"source_name":277,"source_url":274,"published_at":278,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":279,"score_detail":280,"sources":283,"tags":285,"search_phrases":288,"slug":291,"view_count":35,"doi":292,"paper":293,"created_at":321},3169,"Climate change and the rising threat of Macrophomina phaseolina: implications for food security, food safety, and sustainable crop health management","https:\u002F\u002Fdoi.org\u002F10.1007\u002Fs10725-026-01525-5","Abstract Macrophomina phaseolina is a destructive soil-borne necrotrophic fungal pathogen that causes substantial yield losses in a wide range of economically important crops worldwide. Disease severity is strongly enhanced under drought, high temperature, and salinity stress, conditions that are becoming increasingly prevalent under current climate change scenarios. This review examines the interactions between climate-driven abiotic stress, host physiological regulation, and pathogen aggressiveness, highlighting how stress-induced disruptions in hormonal signalling, reactive oxygen species homeostasis, antioxidant defence systems, and plant metabolism collectively increase susceptibility to M. phaseolina . Recent advances in understanding pathogen virulence mechanisms, plant immune responses, and resistance-associated molecular pathways are synthesised together with emerging evidence from transcriptomics, proteomics, metabolomics, and comparative genomics. The review further evaluates current management strategies, including host resistance, biological control, plant growth-promoting microorganisms, stress priming, and integrated disease management, while discussing their limitations under field conditions. Emerging technologies such as precision agriculture, remote sensing, artificial intelligence-assisted disease forecasting, and multi-omics approaches are highlighted as promising tools for improving early diagnosis, risk prediction, and climate-resilient disease management. By integrating advances in plant physiology, molecular biology, and sustainable crop protection, this review provides a comprehensive framework for understanding M. phaseolina pathogenesis under changing environmental conditions. It identifies key research priorities to improve crop resilience and safeguard global food security.","摘要 菜豆壳球孢（Macrophomina phaseolina）是一种具有破坏性的土传死体营养型真菌病原菌，在全球范围内对多种具有重要经济价值的作物造成严重产量损失。在干旱、高温和盐胁迫条件下，病害严重程度显著加剧，而这些条件在当前气候变化情景下正变得越来越普遍。本文综述了气候驱动的非生物胁迫、寄主生理调控与病原菌致病力之间的相互作用，重点阐述了胁迫诱导的激素信号传导紊乱、活性氧稳态失衡、抗氧化防御系统受损以及植物代谢改变如何共同增加对菜豆壳球孢的易感性。本文综合了病原菌毒力机制、植物免疫反应及抗性相关分子通路方面的最新研究进展，并结合转录组学、蛋白质组学、代谢组学和比较基因组学的新兴证据。本文进一步评估了当前的管理策略，包括寄主抗性、生物防治、植物促生微生物、胁迫 priming 和病害综合管理，同时讨论了这些策略在田间条件下的局限性。精准农业、遥感、人工智能辅助病害预测和多组学方法等新兴技术被重点介绍为改善早期诊断、风险预测和气候韧性病害管理的有前景的工具。通过整合植物生理学、分子生物学和可持续作物保护方面的进展，本文为理解变化环境条件下菜豆壳球孢的致病机制提供了综合框架，并确定了提高作物韧性和保障全球粮食安全的关键研究优先方向。","Plant Growth Regulation","2026-09-22T00:00:00Z",80,{"impact":17,"substance":281,"depth":17,"authority":69,"freshness":13,"relevant":21,"comment":282},20,"核心期刊综述，系统梳理气候胁迫下土传病害机制与AI遥感等智慧防控手段，对农业信息化与粮食安全主题有聚合价值。",[284],{"name":277,"url":274},[286,26,287,75,28],"智慧农业","植物病害",[289,290],"Macrophomina phaseolina 病害 防控","气候变暖 土传病害 粮食安全","Macrophominaphaseolina病害防控-3169","10.1007\u002Fs10725-026-01525-5",{"doi":292,"openalex_id":294,"authors":295,"venue":277,"cited_by_count":35,"oa_url":274,"card":315,"direction":50,"ingested_from":52},"W7213972258",[296,298,300,303,306,309,312],{"name":297,"orcid":9},"Sindiswa Khawula",{"name":299,"orcid":9},"Siyabonga Ntshalitshali",{"name":301,"orcid":302},"Arun Gokul","https:\u002F\u002Forcid.org\u002F0000-0003-1575-0632",{"name":304,"orcid":305},"Lee‐Ann Niekerk","https:\u002F\u002Forcid.org\u002F0000-0002-9788-3131",{"name":307,"orcid":308},"Ashwil Klein","https:\u002F\u002Forcid.org\u002F0000-0002-5606-886X",{"name":310,"orcid":311},"Marshall Keyster","https:\u002F\u002Forcid.org\u002F0000-0002-8718-736X",{"name":313,"orcid":314},"Mbukeni Nkomo","https:\u002F\u002Forcid.org\u002F0000-0002-7652-1588",{"tldr":316,"method":317,"finding":318,"direction":319,"opportunity":320},"综述气候变化下干旱高温盐胁迫加剧菜豆壳球孢菌病害的机制与可持续防控策略。","整合转录组、蛋白组、代谢组、比较基因组及精准农业、遥感、AI预测等技术。","气候胁迫破坏激素与ROS平衡降低作物抗性，需多组学与智能技术实现早期预警和抗性管理。","农业人工智能与决策模型","可构建融合多组学与气象遥感的AI病害预警模型，并研发胁迫 priming 与生防协同的田间方案。","2026-09-22T23:30:22.790623Z"]
