This study employs a Dynamic ARDL simulation framework on national data from 1983 to 2023 to dissect the short- and long-run effects of irrigated area, cultivated land, fertilizer use, and agricultural mechanization on grain yield. Long-run elasticities reveal that irrigated area, cultivated land, and fertilizer exert positive and significant effects on grain yield, whereas mechanization exhibits a negative coefficient. Short-run dynamics indicate that only irrigation and cultivated land confer immediate benefits; mechanization and fertilizer effects materialize over multiple years, with a stable and rapid error-correction mechanism confirming swift adjustment toward equilibrium. Dynamic simulations further reveal three robust patterns: positive irrigation and land shocks generate sustained yield gains; mechanization shocks initially suppress yield before a delayed recovery; and fertilizer shocks are fundamentally asymmetric—positive shocks stabilize yields at higher levels, whereas negative shocks paradoxically produce short-run spikes followed by substantial long-run losses. Policy should prioritize gradual fertilizer reduction, irrigation expansion in water-scarce regions, and a fundamental shift in mechanization subsidies from horsepower to yield efficiency.","中国粮食产量对农业投入冲击的动态响应，以及这些响应在短期与长期之间是否存在差异，仍未得到充分理解。本研究基于1983—2023年全国数据，采用动态ARDL模拟框架，剖析灌溉面积、耕地面积、化肥施用和农业机械化对粮食产量的短期与长期效应。长期弹性表明，灌溉面积、耕地面积和化肥对粮食产量具有显著正向影响，而机械化则呈现负向系数。短期动态显示，只有灌溉和耕地能够带来即时收益；机械化和化肥效应需经过多年才能显现，稳定且快速的误差修正机制证实了向均衡的迅速调整。动态模拟进一步揭示了三种稳健模式：灌溉和耕地正向冲击产生持续的产量增长；机械化冲击最初抑制产量，随后延迟恢复；化肥冲击则具有根本性的非对称特征——正向冲击使产量稳定在较高水平，而负向冲击 paradoxically 先引起短期骤增，随后造成长期大幅损失。政策应优先推进化肥减量、在水资源短缺地区扩大灌溉，并从根本上将机械化补贴重心从马力转向产量效率。",null,"Frontiers in Sustainable Food Systems","2026-09-30T00:00:00Z","论文",10,true,85,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},22,23,18,13,9,1,"基于1983—2023年全国数据的动态ARDL研究，揭示化肥冲击的非对称效应与机械化悖论，对粮食稳产政策有实质参考价值。",[25],{"name":10,"url":6},[27,28,29,30,31],"粮食安全","农业机械化","化肥减量","灌溉","农业投入",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"H3","irrigation","水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation","H",[],{"status":40,"locked":41,"version":42,"method":43,"evidence":44},"classified",false,"2026-10-22.2","rules",{"candidates":45,"agricultural_evidence":14},[46,51,59,66],{"code":33,"score":21,"supported":14,"title":47,"abstract":48,"tags":50},[],[30,49,34],"水资源",[],{"code":52,"score":53,"supported":14,"title":54,"abstract":55,"tags":58},"F5",7,[],[56,57],"农业机械","机械化",[28],{"code":60,"score":61,"supported":14,"title":62,"abstract":63,"tags":65},"F3",4,[],[64],"fertilizer",[29],{"code":67,"score":22,"supported":41,"title":68,"abstract":69,"tags":70},"A8",[],[],[27],[72,73],"中国 粮食产量 农业投入","农业机械化 粮食产量 稳定性","中国粮食产量农业投入-3873",3,"10.3389\u002Ffsufs.2026.1878122",{"doi":76,"openalex_id":78,"authors":79,"venue":10,"cited_by_count":91,"oa_url":6,"card":92,"direction":96,"ingested_from":98},"W7214953201",[80,82,84,86,88],{"name":81,"orcid":9},"Baozhong Cai",{"name":83,"orcid":9},"Fang Shi",{"name":85,"orcid":9},"Betelhem A.

On 6 June 2023, the Kakhovka Dam was destroyed. The loss of this critical agricultural and energy infrastructure has left most farmers on the East bank of the Dnipro River without irrigation in Kherson and Zaporizhzhia oblasts. This study develops a multi-sensor Earth Observation framework combining high resolution satellite imagery (Sentinel-2, Landsat) with meteorological data (CHIRPS) and water productivity data (FAO WaPOR), using a semi-supervised machine learning pipeline. Using a rigorous stratified random-sampling approach with photointerpretation, we found pre-war irrigated areas between 2019 to 2021 to be on average 187.94 ± 14.43 kHa, approximately 4% of pre-war baseline cropland and 8% of summer season cropland in Kherson and Zaporizhzhia oblasts. In 2022, these numbers contracted to 140.04 ± 17.44 kHa with the expanded occupation of these territories by Russia, seeing an additional decline in 2023 to 74.97 ± 17.84 kHa. Fields in 2023 also exhibited variability in irrigation, ranging from interrupted irrigation owing to the destruction of the Kakhovka reservoir, to those that were sufficiently irrigated with water remaining in the channels. Irrigated areas diminished further in 2024 to 15.95 ± 9.97 kHa, a ∼91% decline from pre-war averages. Based on inspection, formerly irrigated fields before 2023 were either systematically abandoned or converted to winter cropland with lower input requirements by 2024–a pattern that continued into 2025 (total irrigated area 5.76 ± 0.87 kHa). This study demonstrates the power of advanced EO workflows to precisely quantify agricultural transformation and infrastructural failure in ground-truth deficient, high-risk environments.","乌克兰持续不断的战争使国际社会关注冲突对全球农业生产和粮食安全的影响。2023年6月6日，卡霍夫卡大坝被毁。这一关键农业和能源基础设施的丧失，使第聂伯河（Dnipro River）东岸赫尔松州和扎波罗热州的大多数农民失去了灌溉条件。本研究开发了一个多传感器地球观测（Earth Observation）框架，将高分辨率卫星影像（Sentinel-2、Landsat）与气象数据（CHIRPS）和水生产力数据（FAO WaPOR）相结合，采用半监督机器学习流程。通过严格的 stratified random-sampling 方法并结合照片判读，我们发现2019年至2021年战前灌溉面积平均为187.94 ± 14.43 kHa，约占赫尔松州和扎波罗热州战前基线耕地面积的4%，以及夏季作物耕地面积的8%。2022年，随着俄罗斯对这些领土占领的扩大，上述数字缩减至140.04 ± 17.44 kHa，2023年进一步下降至74.97 ± 17.84 kHa。2023年的田块在灌溉方面也表现出差异性，从因卡霍夫卡水库被毁而灌溉中断，到因渠道中仍有存水而得到充分灌溉的情况不等。2024年，灌溉面积进一步减少至15.95 ± 9.97 kHa，较战前平均值下降约91%。根据核查，2023年之前曾受灌溉的田块到2024年要么被系统性弃耕，要么转为投入需求较低的冬季作物用地——这一模式延续至2025年（总灌溉面积为5.76 ± 0.87 kHa）。本研究表明，先进的地球观测工作流程能够在缺乏地面真值、高风险的环境中精确量化农业转型和基础设施失效。","Frontiers in Remote Sensing","2026-10-05T00:00:00Z",87,{"impact":17,"substance":113,"depth":114,"authority":20,"freshness":21,"relevant":22,"comment":115},24,19,"用半监督多源遥感量化战区灌溉萎缩，方法新颖、数据扎实，对农业遥感与粮食安全研究有参考价值。",[117],{"name":109,"url":106},[27,119,120,121,30],"遥感监测","冲突农业","多源遥感",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},[124],{"code":125,"slug":126,"name":127,"path":128,"parent_code":129},"I3","remote-sensing","遥感与农情监测","\u002Ftopic\u002Fdigital-agriculture\u002Fremote-sensing","I",{"status":40,"locked":41,"version":42,"method":43,"evidence":131},{"candidates":132,"agricultural_evidence":14},[133,138,143,148,155],{"code":33,"score":134,"supported":14,"title":135,"abstract":136,"tags":137},14,[34],[30,34],[],{"code":125,"score":13,"supported":14,"title":139,"abstract":141,"tags":142},[140],"remote sensing",[],[121,119],{"code":67,"score":53,"supported":14,"title":144,"abstract":145,"tags":147},[],[27,146],"food security",[27],{"code":149,"score":101,"supported":14,"title":150,"abstract":151,"tags":154},"I2",[],[152,153],"机器学习","machine learning",[],{"code":156,"score":75,"supported":14,"title":157,"abstract":158,"tags":160},"J3",[],[159],"全球农业",[],[162,163],"冲突农业 多源遥感 粮食安全 遥感监测","冲突农业 多源遥感","冲突农业多源遥感粮食安全遥感监测-4313","10.3389\u002Ffrsen.2026.1920951",{"doi":165,"openalex_id":167,"authors":168,"venue":109,"cited_by_count":91,"oa_url":199,"card":200,"direction":204,"ingested_from":98},"W7220438608",[169,172,175,178,181,184,187,189,191,193,196],{"name":170,"orcid":171},"Sheila Baber","https:\u002F\u002Forcid.org\u002F0000-0002-5596-8970",{"name":173,"orcid":174},"Sergii V.

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":19,"substance":217,"depth":218,"authority":219,"freshness":101,"relevant":22,"comment":220},20,17,12,"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。",[222],{"name":213,"url":210},[224,27,225,226,227],"智慧农业","气候变化","适应性策略","水资源短缺",{"code":229,"slug":230,"name":231,"path":232,"parent_code":37},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate",[234],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":41,"version":42,"method":43,"evidence":236},{"candidates":237,"agricultural_evidence":14},[238,245,249,253,260,267,274,280],{"code":229,"score":19,"supported":14,"title":239,"abstract":241,"tags":244},[240],"climate change",[225,242,240,243],"干旱","drought",[225],{"code":33,"score":21,"supported":14,"title":246,"abstract":247,"tags":248},[],[30,49,34],[],{"code":67,"score":53,"supported":14,"title":250,"abstract":251,"tags":252},[],[27,146],[27],{"code":254,"score":101,"supported":14,"title":255,"abstract":256,"tags":259},"A2",[],[257,258],"小麦","wheat",[],{"code":261,"score":101,"supported":14,"title":262,"abstract":263,"tags":266},"A3",[],[264,265],"玉米","maize",[],{"code":268,"score":101,"supported":14,"title":269,"abstract":270,"tags":273},"A6",[],[271,272],"棉花","cotton",[],{"code":275,"score":61,"supported":14,"title":276,"abstract":277,"tags":279},"I1",[],[278],"smart agriculture",[224],{"code":281,"score":75,"supported":14,"title":282,"abstract":283,"tags":285},"H6",[],[284],"农业生态",[],[287,288],"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":291,"authors":292,"venue":213,"cited_by_count":91,"oa_url":210,"card":299,"direction":305,"ingested_from":98},"W7222907396",[293,295,297],{"name":294,"orcid":9},"Mohammad Shafiq Faieq",{"name":296,"orcid":9},"Mustafa Abid",{"name":298,"orcid":9},"Abdul khalil Afghani",{"tldr":300,"method":301,"finding":302,"direction":303,"opportunity":304},"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。","农业绿色发展与碳","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。","智慧农业 \u002F 农业物联网","2026-10-19T23:30:11.285828Z",{"id":308,"title":309,"url":310,"summary":311,"summary_zh":312,"content":9,"source_name":313,"source_url":310,"published_at":314,"category":12,"cover_url":9,"hotness":13,"is_selected":41,"score":15,"score_detail":315,"sources":318,"tags":320,"primary_topic":325,"secondary_topics":330,"classification":332,"search_phrases":360,"slug":363,"view_count":91,"doi":364,"paper":365,"created_at":382},4887,"Farming under fire: Conflict, displacement, and the collapse of food security in south Lebanon","https:\u002F\u002Fdoi.org\u002F10.1016\u002Fj.jrurstud.2026.104458","Context Lebanon's agricultural sector and food systems are facing unprecedented pressures amid overlapping crises: economic collapse, climate change, and the 2023-2025 armed conflict with Israel. Objective This paper investigates the compounded impact of conflict-induced displacement and climate stress on rural livelihoods, agricultural productivity, and food security in South Lebanon-an area marked by strategic agricultural value and climate vulnerability. Methods Drawing on 29 in-depth interviews with displaced farmers, cooperative leaders, and food producers from conflict-affected areas such as Marjayoun, Nabatieh, and Bint Jbeil, this qualitative study uncovers key disruptions in agricultural infrastructure, local markets, and household food access. Interview findings are also triangulated with published secondary quantitative data (IPC, FAO, WFP, and World Bank assessments). Results and conclusion s: The findings reveal how displacement led to the abandonment of farms, loss of livestock, contamination of crops, and collapse of cooperative models, exacerbating existing economic and climate stressors like currency depreciation, water scarcity, unpredictable rainfall, and reduced yields. Gendered impacts, informal solidarity mechanisms, and persistent energy and input shortages emerged as critical themes. The study highlights the urgent need for an integrated recovery strategy focused on smart irrigation, climate-resilient crops, market reintegration, and financial support for smallholders. The analysis is guided by a conceptual framework that treats conflict-induced displacement and climate stress as interlocking drivers of livelihood erosion, market collapse, and food and nutrition insecurity, with gendered and refugee-specific vulnerabilities at the core. Significance As Lebanon faces a worsening food insecurity crisis, with 1.17 million people in IPC Phase 3 or higher, rebuilding agriculture is no longer a developmental luxury but an existential necessity for national food security.","背景 黎巴嫩的农业部门和粮食系统在多重危机交织下面临前所未有的压力：经济崩溃、气候变化以及2023至2025年与以色列的武装冲突。目标 本文研究冲突导致的流离失所与气候压力对黎巴嫩南部农村生计、农业生产力和粮食安全的叠加影响——该地区具有重要的农业战略价值和气候脆弱性。方法 本定性研究基于对来自马尔杰永、纳巴蒂耶和宾特朱拜勒等受冲突影响地区的流离失所农民、合作社领导人和粮食生产者的29次深度访谈，揭示了农业基础设施、地方市场和家庭粮食获取方面的关键中断。访谈结果还与已发表的二手定量数据（IPC、FAO、WFP和世界银行的评估）进行了三角验证。结果与结论 研究结果揭示了流离失所如何导致农田弃耕、牲畜损失、作物污染和合作社模式崩溃，加剧了现有的经济和气候压力因素，如货币贬值、水资源短缺、降雨不可预测和产量下降。性别影响、非正式互助机制以及持续存在的能源和投入品短缺成为关键主题。研究强调迫切需要一项综合恢复战略，重点关注智能灌溉、气候韧性作物、市场再融入以及对小农户的财政支持。分析以一个概念框架为指导，该框架将冲突导致的流离失所和气候压力视为生计侵蚀、市场崩溃以及粮食和营养不安全的相互关联驱动因素，并将性别和难民特有的脆弱性置于核心位置。意义 随着黎巴嫩面临日益恶化的粮食不安全危机，有117万人处于IPC第3阶段或更高阶段，重建农业不再是一种发展上的奢侈，而是国家粮食安全的生存必需。","Journal of Rural Studies","2026-10-12T00:00:00Z",{"impact":17,"substance":18,"depth":19,"authority":134,"freshness":316,"relevant":22,"comment":317},8,"基于29个深度访谈与IPC\u002FFAO等数据的定性研究，揭示冲突叠加气候压力对南黎巴嫩农业与粮食安全的复合冲击，并提出智慧灌溉与气候韧性作物等恢复策略，对冲突地区农业重建具参考价值。",[319],{"name":313,"url":310},[27,321,322,323,324],"气候韧性","智慧灌溉","小农户支持","冲突与农业",{"code":67,"slug":326,"name":327,"path":328,"parent_code":329},"yield-food-security","单产提升与粮食安全","\u002Ftopic\u002Ffield-crops\u002Fyield-food-security","A",[331],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":41,"version":42,"method":43,"evidence":333},{"candidates":334,"agricultural_evidence":14},[335,340,344,348,354],{"code":67,"score":336,"supported":14,"title":337,"abstract":338,"tags":339},15,[146],[27,146],[27],{"code":33,"score":13,"supported":14,"title":341,"abstract":342,"tags":343},[],[30,49,34],[322],{"code":229,"score":53,"supported":14,"title":345,"abstract":346,"tags":347},[],[225,240],[321],{"code":349,"score":75,"supported":14,"title":350,"abstract":351,"tags":353},"C",[],[352],"livestock",[],{"code":355,"score":75,"supported":14,"title":356,"abstract":357,"tags":359},"G2",[],[358],"小农户",[],[361,362],"南黎巴嫩 粮食安全","冲突 流离失所 生计","南黎巴嫩粮食安全-4887","10.1016\u002Fj.jrurstud.2026.104458",{"doi":364,"openalex_id":366,"authors":367,"venue":313,"cited_by_count":91,"oa_url":310,"card":376,"direction":305,"ingested_from":98},"W7221536688",[368,370,373],{"name":369,"orcid":9},"Yasmine Fakhry",{"name":371,"orcid":372},"Jasmin Lilian Diab","https:\u002F\u002Forcid.org\u002F0000-0003-4158-7728",{"name":374,"orcid":375},"Hussein F.

Traditional drought indices often rely on individual hydroclimatic or vegetation variables and may not fully represent the coupled effects of precipitation supply, atmospheric evaporative demand, and vegetation response. To address this limitation, this study develops and applies a composite drought indicator, the Potential Evapotranspiration–Vegetation–Precipitation Drought Index (PETVPDI), using multi-source remote sensing datasets over WA for 2001–2022. PETVPDI integrates precipitation (P), potential evapotranspiration (PET), and the normalized difference vegetation index (NDVI) within a three-dimensional Euclidean-distance framework. The index was evaluated against GLDAS soil moisture (SM), ESA CCI SM, gross primary productivity (GPP), and net primary productivity (NPP), and compared with four conventional remote-sensing drought indices (cRSDI): VCI, VHI, TVDI, and TVPDI. Deseasonalized anomaly correlations, used as the primary validation evidence to reduce the influence of the shared monsoon seasonal cycle, show that PETVPDI achieved the highest numerical correlations among the evaluated indices with GLDAS SM (R = 0.556, p \u003C 0.001), ESA CCI SM (R = 0.513, p \u003C 0.001), and GPP (R = 0.483, p \u003C 0.001). Steiger’s tests for dependent overlapping correlations show that the PETVPDI–TVPDI difference was statistically significant for raw GLDAS SM and deseasonalized ESA CCI SM, but not for the other evaluated comparisons. Spatial PETVPDI patterns represent each pixel’s relative position within its own 2001–2022 hydroclimatic and vegetation range and therefore should not be interpreted as direct differences in absolute climatic aridity among locations. Long-term trends are spatially heterogeneous across WA. Overall, PETVPDI provides an integrated framework for monitoring relative drought–wetness variability and offers complementary information for drought assessment and early-warning applications in data-scarce regions.","干旱仍然是影响西非（WA）水资源、生态系统和农业生产力最严重的气候相关灾害之一。传统干旱指数通常依赖单一的水文气候或植被变量，可能无法充分反映降水供给、大气蒸发需求和植被响应之间的耦合效应。为解决这一局限，本研究利用2001—2022年西非多源遥感数据集，开发并应用了一种复合干旱指标——潜在蒸散–植被–降水干旱指数（PETVPDI）。PETVPDI在三维欧氏距离框架内整合了降水（P）、潜在蒸散（PET）和归一化差异植被指数（NDVI）。该指数以GLDAS土壤湿度（SM）、ESA CCI SM、总初级生产力（GPP）和净初级生产力（NPP）进行评估，并与四种传统遥感干旱指数（cRSDI）：VCI、VHI、TVDI和TVPDI进行比较。以去季节化异常相关性作为主要验证依据，以减少共同季风季节循环的影响，结果表明PETVPDI在所评估的指数中与GLDAS SM（R = 0.556，p \u003C 0.001）、ESA CCI SM（R = 0.513，p \u003C 0.001）和GPP（R = 0.483，p \u003C 0.001）的数值相关性最高。针对相依重叠相关性的Steiger检验表明，PETVPDI–TVPDI差异在原始GLDAS SM和去季节化ESA CCI SM上具有统计学显著性，但在其他评估比较中不显著。PETVPDI的空间格局表示每个像元在其自身2001—2022年水文气候和植被范围内的相对位置，因此不应被解释为地点之间绝对气候干燥度的直接差异。长期趋势在西非呈现空间异质性。总体而言，PETVPDI为监测相对干旱–湿润变率提供了一个集成框架，并为数据稀缺地区的干旱评估和预警应用提供了补充信息。","Remote Sensing","2026-10-08T00:00:00Z",75,{"impact":219,"substance":17,"depth":19,"authority":134,"freshness":21,"relevant":22,"comment":393},"提出融合降水、蒸散与植被的复合干旱指数，方法新颖、验证扎实，对数据稀缺区农业干旱预警有参考价值，但区域局限于西非，国内应用关联度有限。",[395],{"name":389,"url":386},[27,397,119,398,399],"农业气象","西非农业","干旱指数",{"code":229,"slug":230,"name":231,"path":232,"parent_code":37},[402,403],{"code":125,"slug":126,"name":127,"path":128,"parent_code":129},{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":41,"version":42,"method":43,"evidence":405},{"candidates":406,"agricultural_evidence":14},[407,412,417,422,429],{"code":229,"score":408,"supported":14,"title":409,"abstract":410,"tags":411},16,[243],[242,243],[397,399],{"code":125,"score":336,"supported":14,"title":413,"abstract":414,"tags":416},[140],[415,140],"遥感",[119],{"code":33,"score":134,"supported":14,"title":418,"abstract":420,"tags":421},[419],"evapotranspiration",[49,419],[],{"code":423,"score":101,"supported":14,"title":424,"abstract":425,"tags":428},"H2",[],[426,427],"土壤","soil",[],{"code":67,"score":22,"supported":41,"title":430,"abstract":431,"tags":432},[],[],[27],[434,435],"PETVPDI 干旱指数 西非","遥感 干旱监测 NDVI","PETVPDI干旱指数西非-4504","10.3390\u002Frs18193435",{"doi":437,"openalex_id":439,"authors":440,"venue":389,"cited_by_count":91,"oa_url":386,"card":447,"direction":204,"ingested_from":98},"W7220963372",[441,444],{"name":442,"orcid":443},"Abdoul-Aziz Bio Sidi D.
