uses Sentinel-2 imagery to characterize seasonal vegetation dynamics in the analysed part of the Ialpug River Basin from March to October 2025.Monthly NDVI, month-to-month NDVI differences (ΔNDVI) and mean NDVI were calculated to describe vegetation greenness, the direction and magnitude of change between observations, and average greenness across the study period.The results show spring greening followed by spatially contrasting changes in early summer.Moderate vegetation cover occupied its largest share in April, while dense vegetation reached its maximum extent in June.The most widespread decline occurred between June and July, when 54.18% of the study area recorded an NDVI decrease exceeding 0.1.Very sparse vegetation reached its greatest extent in September, followed by limited greening in October.The mean NDVI classification placed 69.20% of the study area in the sparse vegetation class and 24.49% in the very sparse vegetation class, indicating predominantly low to intermediate average greenness across the selected observations.These classes do not establish persistent vegetation conditions or directly identify land-cover types.The summer decline coincided with documented regional drought conditions, but the analysis did not separate climatic effects from crop development, harvesting or other seasonal processes.The combined indicators provide complementary information for identifying areas with pronounced seasonal decline or low average greenness.Multi-year observations and independent climatic, land-cover and field evidence are required to determine the causes of these patterns and assess their longer-term environmental significance.","本研究利用Sentinel-2影像刻画了雅尔普格河（Ialpug River）流域分析区2025年3月至10月的季节性植被动态。通过计算逐月NDVI、月际NDVI差值（ΔNDVI）及平均NDVI，以描述植被绿度、观测间变化的方向与幅度以及研究期内的平均绿度。结果表明，春季出现绿化，随后在初夏呈现空间分异的变化。中度植被覆盖在4月占比最大，而茂密植被在6月达到最大范围。最广泛的下降发生在6月至7月之间，届时研究区54.18%的面积NDVI下降超过0.1。极稀疏植被在9月达到最大范围，随后在10月出现有限绿化。平均NDVI分类将研究区69.20%的面积归为稀疏植被类，24.49%归为极稀疏植被类，表明所选观测期内平均绿度以低至中等为主。这些类别并不确立持续的植被状况，也不直接识别土地覆盖类型。夏季下降与已记录的区域干旱条件相吻合，但分析未将气候影响与作物发育、收割或其他季节性过程区分开来。综合指标为识别季节性下降显著或平均绿度较低的区域提供了互补信息。要确定这些格局的成因并评估其长期环境意义，尚需多年观测以及独立的气候、土地覆盖和野外证据。",null,"Geographia

North Africa, identified as a vulnerability hotspot by the IPCC AR6, experiences intensified droughts and ecosystem degradation. This study presents the first quantitative assessment of climate resilience in El Bayadh Province (Algeria), revealing an unexpected hydro-vegetal paradox. A comparative multi-index methodology (restricted climate index vs. global index integrating 7 variables) was applied to 22 municipalities over the period of 1984 to 2023. The results showed a universal degradation of water balance (-8.2 to -21.4 mm yr-1) and widespread warming (+0.8 to +2.1°C decade-1). Paradoxically, 73 to 77% of municipalities showed improvement in vegetation indices (NDVI, SAVI), suggesting ecological adaptation. Principal component analysis (PCA-99%) variance explained) identified water stress as the main differentiating factor, and clustering distinguishes 5 territorial profiles (silhouette = 0.521). The global index proves more discriminant than the restricted index for capturing the complexity of socio-ecological dynamics.

MODIS NDVI (MOD13Q1), MODIS LST (MOD11A2), and CHIRPS rainfall data were processed in Google Earth Engine to assess environmental change across four phases: baseline (2000-2005), pre-conflict (2010-2013), ISIS conflict (2014-2017), and post-conflict recovery (2018-2024). Vegetation trends were evaluated using the Mann-Kendall test and Sen's Slope estimator. Mean annual NDVI increased by 21.6%, from 0.1995 during the baseline phase to 0.2426 during the recovery phase. Significant greening occurred across 56.2% of the governorate (5,470 km²), while only 0.8% (78 km²) experienced browning. Two major periods of vegetation decline were identified: the 2007-2009 regional drought, when mean NDVI fell to 0.1397, and the 2014-2017 ISIS conflict, during which vegetation declined in western districts despite near-average rainfall, indicating conflict as an independent driver of degradation. Mean annual LST decreased from 38.37 °C in 2000 to 32.33 °C in 2024, consistent with the inverse relationship between vegetation cover and surface temperature. The findings provide quantitative evidence of conflict-driven vegetation degradation followed by post-conflict ecological recovery, offering valuable insights for land management and agricultural recovery planning in semi-arid, post-conflict regions.","本研究对伊拉克北部基尔库克省2000年至2024年间的植被动态与地表温度（LST）进行了24年时空分析。在Google Earth Engine中处理了MODIS NDVI（MOD13Q1）、MODIS LST（MOD11A2）和CHIRPS降雨数据，以评估四个阶段的环境变化：基线期（2000—2005年）、冲突前期（2010—2013年）、ISIS冲突期（2014—2017年）和冲突后恢复期（2018—2024年）。植被趋势采用Mann-Kendall检验和Sen斜率估计法进行评估。年均NDVI增加了21.6%，从基线期的0.1995上升至恢复期的0.2426。显著绿化面积占全省的56.2%（5,470 km²），而仅0.8%（78 km²）出现褐化。研究识别出两个主要的植被退化时期：2007—2009年区域性干旱期间，平均NDVI降至0.1397；以及2014—2017年ISIS冲突期间，尽管降雨量接近平均水平，西部地区的植被仍然退化，表明冲突是植被退化的独立驱动因素。年均LST从2000年的38.37 °C降至2024年的32.33 °C，与植被覆盖和地表温度之间的反比关系一致。研究结果提供了冲突驱动植被退化及冲突后生态恢复的定量证据，为半干旱冲突后地区的土地管理和农业恢复规划提供了有价值的参考。","Journal of Degraded and Mining Lands Management","2026-10-01T00:00:00Z",{"impact":17,"substance":98,"depth":18,"authority":157,"freshness":158,"relevant":21,"comment":218},"基于MODIS与CHIRPS的24年遥感长时序分析，量化干旱与冲突对植被和地表温度的影响，方法规范、数据扎实，对半干旱战后地区农业恢复规划有参考价值，但地域性强、与国内三农信息化关联有限。",[220],{"name":215,"url":212},[27,222,28,49,223],"地表温度","战后农业恢复",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":14,"version":40,"method":41,"evidence":227},{"candidates":228,"agricultural_evidence":46},[229,234],{"code":32,"score":230,"supported":46,"title":231,"abstract":232,"tags":233},14,[50],[49,50],[],{"code":53,"score":54,"supported":14,"title":235,"abstract":236,"tags":237},[],[],[222,28,27],[239,240],"基尔库克 植被动态 遥感","MODIS NDVI 地表温度","基尔库克植被动态遥感-4086","10.15243\u002Fjdmlm.2026.134.10955",{"doi":242,"openalex_id":244,"authors":245,"venue":215,"cited_by_count":76,"oa_url":252,"card":253,"direction":82,"ingested_from":84},"W7214972947",[246,249],{"name":247,"orcid":248},"Azhar Hussein Razuqi","https:\u002F\u002Forcid.org\u002F0009-0002-1202-5953",{"name":250,"orcid":251},"Mustafa Albdairi","https:\u002F\u002Forcid.org\u002F0009-0002-6673-363X","https:\u002F\u002Fjdmlm.ub.ac.id\u002Findex.php\u002Fjdmlm\u002Farticle\u002Fdownload\u002F17867\u002F2159",{"tldr":254,"method":255,"finding":256,"direction":82,"opportunity":257},"分析伊拉克基尔库克2000-2024年植被与地表温度动态，区分干旱与冲突的驱动作用。","MODIS NDVI\u002FLST与CHIRPS降雨数据，在GEE中用Mann-Ken","NDVI总体增21.6%，干旱和ISIS冲突分别导致植被下降，冲突是独立退化驱动因素。","可结合更高分辨率遥感与地面调查，量化冲突后农业恢复力及气候适应策略。","2026-10-03T23:30:32.505144Z",{"id":260,"title":261,"url":262,"summary":263,"summary_zh":264,"content":9,"source_name":265,"source_url":262,"published_at":266,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":267,"score_detail":268,"sources":272,"tags":274,"primary_topic":278,"secondary_topics":279,"classification":280,"search_phrases":296,"slug":299,"view_count":54,"doi":300,"paper":301,"created_at":316},3558,"Meteorolojik Kuraklığın Vejetasyon Sağlığı Üzerindeki Mekânsal ve Zamansal Etkilerinin SPI ve NDVI ile Analizi: Gediz Havzası Örneği","https:\u002F\u002Fdoi.org\u002F10.48123\u002Frsgis.1858019","Kuraklık, özellikle yarı kurak iklim koşullarına sahip havzalarda su kaynakları, tarımsal üretim ve ekosistem sürdürülebilirliği üzerinde belirleyici etkiler oluşturan başlıca doğal afetlerden biridir.

A multi-source methodological approach was adopted, combining the inventory and mapping of springs, the application of remote sensing, using Landsat and Sentinel satellite imagery, and the calculation of standard indices, including the Normalized Difference Water Index (NDWI), the Normalized Difference Vegetation Index (NDVI), and the Standardized Precipitation Index (SPI). The results indicate that a combination of geomorphological context primarily influences the spatial distribution of the 101 inventoried springs, the lithological nature of the formations (permeable dolomites), structural features, and climatic factors. However, a significant regression in both the number and flow of these springs has been observed. Concurrently, irrigated fruit agriculture has expanded remarkably over the study period.

Rising temperatures, increased evapotranspiration, irregular precipitation, droughts, flooding, and sea-level rise can intensify salt accumulation and alter soil–water interactions. This review examines the emerging challenges associated with climate change and soil salinity in Pakistan, focusing on their impacts on soil properties, crop physiology, agricultural production, and rural livelihoods. It discusses the mechanisms of soil salinity and sodicity, their spatial distribution, and the interactions among climate variability, irrigation practices, groundwater quality, and secondary salinization. Furthermore, sustainable management approaches are evaluated, including gypsum application, organic amendments, integrated nutrient management, efficient irrigation, drainage improvement, and appropriate leaching strategies. Climate-resilient approaches, such as conventional crop breeding, modern biotechnology, halophyte utilization, plant growth-promoting microorganisms, and mycorrhizal associations, are also explored. The review highlights the potential of remote sensing, geographic information systems, precision agriculture, and predictive modelling to support salinity monitoring and site-specific management. Despite these opportunities, important challenges remain, including insufficient long-term monitoring, limited region-specific data, economic constraints, and gaps in farmer awareness and institutional coordination. Addressing these challenges requires integrated research, effective agricultural policies, improved extension services, and collaboration among researchers, policymakers, and farming communities. Prioritizing locally adapted, economically feasible, and environmentally sustainable interventions can strengthen agricultural resilience, restore salt-affected soils, and protect freshwater resources. Overall, integrating climate adaptation with sustainable soil and water management is essential for maintaining agricultural productivity and improving long-term food security in Pakistan.","土壤盐渍化是制约巴基斯坦农业生产力、土壤健康和粮食安全的主要因素，在气候变化条件下尤为突出。气温升高、蒸散加剧、降水不规律、干旱、洪水以及海平面上升可能加剧盐分积累并改变土壤—水相互作用。本文综述了巴基斯坦气候变化与土壤盐渍化相关的新兴挑战，重点关注其对土壤性质、作物生理、农业生产和农村生计的影响。文章讨论了土壤盐渍化和钠质化的机制、其空间分布，以及气候变率、灌溉实践、地下水质量和次生盐渍化之间的相互作用。此外，评估了可持续管理途径，包括施用石膏、有机改良、综合养分管理、高效灌溉、排水改良和适宜的淋洗策略。还探讨了气候韧性方法，如常规作物育种、现代生物技术、盐生植物利用、植物促生微生物和菌根共生。本文强调了遥感、地理信息系统、精准农业和预测建模在支持盐渍化监测和因地制宜管理方面的潜力。尽管存在这些机遇，重要挑战依然存在，包括长期监测不足、区域特定数据有限、经济制约以及农民意识和制度协调方面的差距。应对这些挑战需要综合研究、有效的农业政策、改进的推广服务以及研究人员、政策制定者和农业社区之间的协作。优先采取适应当地、经济可行且环境可持续的干预措施，可增强农业韧性、修复盐渍化土壤并保护淡水资源。总体而言，将气候适应与可持续水土管理相结合，对于维持巴基斯坦农业生产力和改善长期粮食安全至关重要。","Kashmir Journal of Academic Research and Development","2026-10-20T00:00:00Z",66,{"impact":157,"substance":18,"depth":19,"authority":20,"freshness":17,"relevant":21,"comment":406},"综述性论文，系统梳理气候变化下巴基斯坦土壤盐渍化成因与可持续治理路径，兼具遥感与精准农业视角，对盐碱地治理议题有参考价值，但属区域性综述、非突破性成果。",[408],{"name":402,"url":399},[103,410,27,411,412],"盐碱地治理","智慧灌溉","土壤盐渍化",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[415,420],{"code":416,"slug":417,"name":418,"path":419,"parent_code":36},"H2","soil","土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil",{"code":116,"slug":343,"name":344,"path":345,"parent_code":36},{"status":39,"locked":14,"version":40,"method":41,"evidence":422},{"candidates":423,"agricultural_evidence":46},[424,428,433,438,443,447,454,461,467],{"code":32,"score":18,"supported":46,"title":425,"abstract":426,"tags":427},[358],[103,163,49,358],[103],{"code":416,"score":19,"supported":46,"title":429,"abstract":430,"tags":432},[417],[431,417],"土壤",[410],{"code":116,"score":13,"supported":46,"title":434,"abstract":435,"tags":437},[],[119,120,343,436],"evapotranspiration",[411],{"code":53,"score":439,"supported":46,"title":440,"abstract":441,"tags":442},7,[],[353,351],[27],{"code":177,"score":45,"supported":46,"title":444,"abstract":445,"tags":446},[],[180,181],[],{"code":448,"score":45,"supported":46,"title":449,"abstract":450,"tags":453},"I1",[],[451,452],"精准农业","precision agriculture",[],{"code":455,"score":45,"supported":46,"title":456,"abstract":457,"tags":460},"I4",[],[458,459],"地理信息","geographic information",[],{"code":462,"score":54,"supported":46,"title":463,"abstract":464,"tags":466},"F3",[],[465],"养分管理",[],{"code":468,"score":54,"supported":46,"title":469,"abstract":470,"tags":472},"J1",[],[471],"农业政策",[],[474,475],"巴基斯坦 土壤盐渍化","盐碱地 遥感监测","巴基斯坦土壤盐渍化-5483","10.71317\u002Fkjard.2.10.2026.883",{"doi":477,"openalex_id":479,"authors":480,"venue":402,"cited_by_count":76,"oa_url":399,"card":496,"direction":82,"ingested_from":84},"W7222999158",[481,483,485,487,489,491,494],{"name":482,"orcid":9},"Asifa Naz",{"name":484,"orcid":9},"Muhammad Abu Baker Siddiq",{"name":486,"orcid":9},"Syed Asghar Hussain Shah",{"name":488,"orcid":9},"Shahrish Nawaz",{"name":490,"orcid":9},"Muhmmad Irfan",{"name":492,"orcid":493},"Rizwana Kausar","https:\u002F\u002Forcid.org\u002F0000-0002-1339-3312",{"name":495,"orcid":9},"Muhammad Nouman Khalid",{"tldr":497,"method":498,"finding":499,"direction":82,"opportunity":500},"综述气候变化下巴基斯坦土壤盐渍化的挑战与可持续管理途径。","文献综述，整合盐渍化机制、空间分布及遥感GIS与预测模型应用。","需将气候适应与水土管理结合，优先本地化、经济可行的干预措施。","可填补长期盐渍化监测与区域数据空白，发展遥感+预测模型的精准分区治理。","2026-10-21T23:30:23.059448Z"]
