With the threat of drought leading to a decline in wetlands and shifts in seasonality patterns in the NACP, there is significant concern about the effects of a drying climate on the net primary productivity of bald cypress-tupelo swamps and the potential for ecosystem degradation or conversion. This study seeks to understand the relationship between the net primary productivity of wetlands dominated by bald cypress-tupelo swamps and drought conditions. We used Moderate Resolution Imaging Spectroradiometer (MODIS) imagery from 2000 to 2024, taken from the 500 largest flooded forest swamps in the southeastern USA using Google Earth Engine, to track the changes in productivity of these swamps over time. The trends in MODIS Fraction of Absorbed Photosynthetically Active Radiation (FPAR), Normalized Difference Vegetation Index (NDVI), and Enhanced Vegetation Index (EVI) were compared against three common drought indices using seasonal decomposition and linear regression along with local bivariate spatial associations. We found that while there were small global correlations between drought and productivity metrics, the impact of droughts on these swamps is highly spatially variable, with specific geographical regions displaying differing impacts of drought and precipitation levels on the vegetation productivity. Coastal and southern regions, including the states of Texas, Florida, and Louisiana, are experiencing a decrease in precipitation but have mixed productivity trends. Meanwhile, more inland and coastal northern areas display an increase in precipitation and wetness. Overall, our results suggest that cypress-tupelo swamp productivity varies based on a variety of factors, including, but not limited to, precipitation and drought levels, but some areas may be at risk of further degradation due to drought under future climate change. Further research is encouraged to fully understand vegetation productivity in relation to environmental conditions in individual cypress-tupelo swamps.","气候变化导致美国东南部干旱状况加剧，影响了多种生态系统和物种，其中包括北美沿海平原（NACP）的淡水泛滥森林沼泽。随着干旱威胁导致湿地减少以及NACP季节性模式发生变化，人们对气候干化如何影响落羽杉-紫树沼泽的净初级生产力以及生态系统退化或转变的潜在风险深感担忧。本研究旨在理解以落羽杉-紫树沼泽为主的湿地净初级生产力与干旱状况之间的关系。我们利用Google Earth Engine获取了2000年至2024年期间美国东南部500个最大泛滥森林沼泽的中分辨率成像光谱仪（MODIS）影像，以追踪这些沼泽生产力随时间的变化。我们将MODIS光合有效辐射吸收比例（FPAR）、归一化差异植被指数（NDVI）和增强植被指数（EVI）的趋势与三种常用干旱指数进行比较，采用季节性分解和线性回归以及局部双变量空间关联方法。我们发现，尽管干旱与生产力指标之间存在较小的全局相关性，但干旱对这些沼泽的影响在空间上高度可变，特定地理区域在干旱和降水水平对植被生产力的影响方面表现出差异。沿海和南部地区，包括德克萨斯州、佛罗里达州和路易斯安那州，正在经历降水减少，但生产力趋势不一。与此同时，更内陆和沿海北部地区则显示降水和湿度增加。总体而言，我们的结果表明，落羽杉-紫树沼泽生产力受多种因素影响，包括但不限于降水和干旱水平，但在未来气候变化下，一些地区可能面临因干旱而进一步退化的风险。我们鼓励进一步研究，以充分理解单个落羽杉-紫树沼泽中植被生产力与环境条件的关系。","bioRxiv (Cold Spring Harbor Laboratory)","2026-09-18T00:00:00Z",69,{"impact":20,"substance":72,"depth":73,"authority":20,"freshness":17,"relevant":21,"comment":74},20,17,"基于MODIS 2000-2024年长时序遥感数据评估干旱对北美柏树-图珀洛沼泽生产力的空间异质性影响，方法规范、数据规模大，对湿地生态遥感监测有参考价值，但属基础生态研究，与国内三农信息化直接关联有限。",[76],{"name":68,"url":65},[78,26,27,79,80],"气候变化","湿地生态","植被生产力",[82,83],"北美沿海平原 柏树湿地 干旱","MODIS NDVI 湿地生产力","北美沿海平原柏树湿地干旱-3079","10.64898\u002F2026.09.16.752089",{"doi":85,"openalex_id":87,"authors":88,"venue":68,"cited_by_count":35,"oa_url":98,"card":99,"direction":55,"ingested_from":57},"W7213557702",[89,92,95],{"name":90,"orcid":91},"Isabel Holland","https:\u002F\u002Forcid.org\u002F0000-0002-6416-7729",{"name":93,"orcid":94},"Kayla Stan","https:\u002F\u002Forcid.org\u002F0000-0002-2159-3090",{"name":96,"orcid":97},"Clay S.

But even though people know that reforestation is good for the environment, there isn’t enough local data on how much carbon is stored in these areas, which makes it hard to tell how well they work to fight climate change. This study helped to fix the deficiency of local carbon stock data in reforested areas within the City of Koronadal by employing forest inventory data and remote sensing techniques. The study employed a quantitative research design that integrated field-based forest measurements with remote sensing analysis. NDVI results showed a positive relationship with field data, indicating that remote sensing is a useful tool in measuring NDVI. Measurements were done on tree species, diameter at breast height (DBH), height, and wood density in 200 m perimeter Barangay San Isidro, Barangay Assumption and Barangay San Jose. Allometric equations were used to determine aboveground biomass, which was further transformed into carbon stock according to IPCC. The Landsat 9 satellite images were provided in QGIS and used to compute the Normalized Difference Vegetation Index (NDVI) and to evaluate vegetation cover. The findings indicate a difference between the sites with Barangay San Jose (0.16 t C\u002Fha) and Barangay Assumption (NDVI 0.50) having higher biomass and carbon stock which are dominated mainly by Swietenia macrophylla (Mahogany) for monitoring forest biomass.

However, this fragile dryland ecosystem is increasingly threatened by armed conflict, large-scale displacement, land use changes, and environmental degradation. Therefore, this study assessed the status of GAB and gum production under conflict-induced stressors using an integrated methodology that combines meteorological, remote sensing, and participatory field survey data. Multi-temporal MODIS NDVI data (2000–2023) were analyzed to detect spatiotemporal changes in vegetation cover, particularly during peak growing seasons. Normalized Difference Vegetation Index (NDVI) trends were evaluated using five-year intervals, except for the last period (2020–2023) to accommodate the eco-anthropogenic signs of the current war. The results reveal that vegetation recovery across large portions of the GAB is correlated with land abandonment due to ongoing conflict and locals’ displacement. Across all assessed years, moderate vegetation class consistently dominated the landscape, particularly in 2020 and 2023, indicating a notable improvement in vegetation cover in recent years. A significant variation was observed in Gum yield, with higher production in 2005. The study underscores the urgent need for target restoration strategies and sustainable management policies. It also demonstrates the value of integrating earth observation data with local knowledge systems for conflict-sensitive environmental monitoring and policy formation in dryland regions.","摘要 苏丹的阿拉伯胶带（Gum Arabic Belt, GAB）在维持农村生计、支持生物多样性和提供关键生态系统服务方面发挥着重要作用。然而，这一脆弱的旱地生态系统正日益受到武装冲突、大规模流离失所、土地利用变化和环境退化的威胁。因此，本研究采用综合气象、遥感和参与式实地调查数据的方法，评估了冲突引发的压力因素下GAB及阿拉伯胶生产的状况。研究分析了多时相MODIS NDVI数据（2000–2023年），以检测植被覆盖的时空变化，尤其是生长旺季期间的变化。归一化植被指数（NDVI）趋势按五年间隔进行评估，但最后一个时段（2020–2023年）除外，以适应当前战争带来的生态-人为影响迹象。结果表明，GAB大部分地区的植被恢复与持续冲突和当地居民流离失所导致的土地撂荒相关。在所有评估年份中，中等植被等级始终主导景观，尤其是在2020年和2023年，表明近年来植被覆盖显著改善。阿拉伯胶产量存在显著差异，2005年产量较高。该研究强调迫切需要有针对性的恢复策略和可持续管理政策。研究还表明，将地球观测数据与当地知识系统相结合，对于旱地地区冲突敏感型环境监测和政策制定具有重要价值。","Scientific Reports",77,{"impact":160,"substance":161,"depth":18,"authority":162,"freshness":17,"relevant":21,"comment":163},16,21,14,"以MODIS NDVI长时序遥感结合实地调查评估冲突扰动下阿拉伯胶带植被与胶产量变化，方法扎实、结论有政策价值，但属区域案例研究，对国内三农信息化参考有限。",[165],{"name":157,"url":154},[26,27,167,168,169],"荒漠化防治","可持续管理","苏丹",[171,172],"苏丹 阿拉伯胶带 NDVI","MODIS NDVI 植被覆盖 冲突","苏丹阿拉伯胶带NDVI-3075","10.1038\u002Fs41598-026-69562-8",{"doi":174,"openalex_id":176,"authors":177,"venue":157,"cited_by_count":35,"oa_url":185,"card":186,"direction":55,"ingested_from":57},"W7213533975",[178,181,183],{"name":179,"orcid":180},"Elmugheira M.

However, human activities and natural hazards may conduct to ecosystem degradation and loss of biodiversity and consequently, to business risks. In arid regions, oasis ecosystems have a crucial economic and social impact. However, natural and anthropogenic factors may affect oases ecosystems and their services. Therefore, the main objective of this research is to assess changes in oasis ecosystems in southern Tunisia using multi-temporal satellite images and NDVI analysis. The methodology is based on Landsat satellite data acquired between 1995 and 2025 and the calculation of NDVI. The results shows that the oasis areas in the study area increased by 42.36%. While this expansion reflects agricultural intensification, it may also lead to higher water consumption, soil degradation and biodiversity loss. This research can help local stakeholders better understand environmental risks and support the development of appropriate strategies to preserve oasis ecosystems.","许多生态系统面临多重压力，影响其提供生态系统服务的能力。这些服务通常分为四类：供给服务、调节服务、文化服务和支持服务。这些服务可为当地社区带来商业机会。然而，人类活动和自然灾害可能导致生态系统退化和生物多样性丧失，进而带来商业风险。在干旱地区，绿洲生态系统具有重要的经济和社会影响。然而，自然和人为因素可能影响绿洲生态系统及其服务。因此，本研究的主要目标是利用多时相卫星影像和NDVI分析评估突尼斯南部绿洲生态系统的变化。该方法基于1995年至2025年间获取的Landsat卫星数据和NDVI计算。结果表明，研究区内的绿洲面积增加了42.36%。虽然这一扩张反映了农业集约化，但也可能导致更高的水资源消耗、土壤退化和生物多样性丧失。本研究可帮助当地利益相关者更好地理解环境风险，并支持制定适当的策略以保护绿洲生态系统。","JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT","2026-09-11T00:00:00Z",68,{"impact":20,"substance":72,"depth":160,"authority":20,"freshness":17,"relevant":21,"comment":202},"基于1995—2025年Landsat影像与NDVI分析突尼斯南部绿洲扩张及其生态代价，方法规范、数据跨度长，对干旱区农业遥感与生态风险研究有参考价值，但属区域案例，公共影响有限。",[204],{"name":198,"url":195},[26,27,206,207,167],"生态系统服务","绿洲农业",[209,210],"生态系统服务 荒漠化防治 绿洲农业 遥感监测","生态系统服务 荒漠化防治","生态系统服务荒漠化防治绿洲农业遥感监测-2436","10.56027\u002Fjoasd.112026",{"doi":212,"openalex_id":214,"authors":215,"venue":198,"cited_by_count":35,"oa_url":220,"card":221,"direction":55,"ingested_from":57},"W7212394548",[216,218],{"name":217,"orcid":9},"Abdelaziz Ben Abdallah",{"name":219,"orcid":9},"Mohamed Kefi","https:\u002F\u002Fwww.joasdjournal.org\u002Findex.php\u002Fjoasd\u002Farticle\u002Fdownload\u002F347\u002F306",{"tldr":222,"method":223,"finding":224,"direction":55,"opportunity":225},"用Landsat多时相影像和NDVI分析突尼斯南部绿洲1995-2025年扩张及其对生态系统服务的影","Landsat多时相影像（1995-2025）与NDVI计算，评估绿洲面积变化。","绿洲面积增加42.36%，但扩张可能加剧水资源消耗、土壤退化和生物多样性丧失。","可结合多源遥感与生态系统服务模型，量化绿洲扩张对水资源和碳储的权衡关系。","2026-09-14T23:30:27.585327Z",{"id":228,"title":229,"url":230,"summary":231,"summary_zh":232,"content":9,"source_name":233,"source_url":230,"published_at":199,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":234,"score_detail":235,"sources":237,"tags":239,"search_phrases":242,"slug":245,"view_count":35,"doi":246,"paper":247,"created_at":262},2429,"Türkiye’de durağan orman alanlarında 2001 ve 2025 yılları arasında yer yüzey fenolojilerindeki değişimlerin incelenmesi","https:\u002F\u002Fdoi.org\u002F10.53516\u002Fajfr.1970696","Giriş ve Hedefler Orman alanlarındaki yer yüzey fenolojilerinin (YYF) değişiminin izlenmesi iklim değişikliğine uyum ve sürdürülebilir doğal kaynak yönetimi açısından oldukça önemlidir.

This study investigated vegetation change and climate variability in the Jabel Marra region of Central Darfur, Sudan, during 1994–2024 using Landsat-derived Normalized Difference Vegetation Index (NDVI), CHIRPS precipitation, MERRA-2 temperature, and the Standardized Precipitation Evapotranspiration Index (SPEI). Long-term vegetation trends were assessed using the Mann-Kendall trend test and Sen’s slope estimator, whereas climate–vegetation relationships were evaluated using correlation analysis. The annual NDVI showed a significant positive trend (Mann–Kendall Z = 4.78, p \u003C 0.001), with a Sen’s slope of 0.00143 NDVI units year⁻¹, indicating a gradual increase in vegetation greenness. Spatial trend analysis showed that positive vegetation trends were concentrated primarily in mid-to-high elevation vegetated areas. Annual precipitation exhibited substantial interannual variability (R² = 0.06), whereas temperature increased consistently (R² = 0.51). NDVI was positively correlated with precipitation ( r = 0.48) and negatively correlated with temperature ( r = − 0.57). The SPEI identified recurrent drought episodes before 2018, followed by predominantly wetter conditions thereafter. The findings indicate that vegetation dynamics in Jabel Marra were primarily associated with climatic variability, particularly precipitation and drought conditions, while conflict-related processes were considered contextual because they were not directly analyzed. This study demonstrates the value of integrating long-term satellite observations and climate datasets to monitor vegetation changes in data-scarce dryland environments.","理解半干旱和受冲突影响环境中的长期植被动态，对于可持续土地管理和气候适应具有重要意义。本研究利用基于Landsat的归一化植被指数（NDVI）、CHIRPS降水数据、MERRA-2温度数据以及标准化降水蒸散指数（SPEI），调查了苏丹中达尔富尔州杰贝尔马拉地区1994—2024年的植被变化与气候变率。长期植被趋势采用Mann-Kendall趋势检验和Sen斜率估计法进行评估，气候—植被关系则通过相关分析进行评价。年NDVI呈显著正趋势（Mann-Kendall Z = 4.78，p \u003C 0.001），Sen斜率为0.00143 NDVI单位·年⁻¹，表明植被绿度逐渐增加。空间趋势分析显示，植被正向趋势主要集中在中高海拔植被区。年降水量表现出较大的年际变率（R² = 0.06），而温度则持续上升（R² = 0.51）。NDVI与降水量呈正相关（r = 0.48），与温度呈负相关（r = −0.57）。SPEI识别出2018年之前反复出现的干旱事件，此后则以偏湿润条件为主。研究结果表明，杰贝尔马拉地区的植被动态主要与气候变率相关，尤其是降水量和干旱状况，而冲突相关过程因未被直接分析，仅作为背景因素加以考虑。本研究证明了整合长期卫星观测和气候数据集以监测数据稀缺干旱区环境植被变化的价值。","Environmental Earth Sciences","2026-09-10T00:00:00Z",66,{"impact":17,"substance":72,"depth":73,"authority":273,"freshness":17,"relevant":21,"comment":274},13,"基于30年Landsat与气候数据的半干旱冲突区植被动态研究，方法规范、结论可靠，对旱区土地管理与气候适应有参考价值，但属区域案例研究，公共影响有限。",[276],{"name":269,"url":266},[26,278,27,279,280],"气候适应","干旱区农业","植被变化",[282,283],"干旱区农业 植被变化 气候适应 遥感监测","干旱区农业 植被变化","干旱区农业植被变化气候适应遥感监测-2328","10.1007\u002Fs12665-026-13109-7",{"doi":285,"openalex_id":287,"authors":288,"venue":269,"cited_by_count":35,"oa_url":303,"card":304,"direction":55,"ingested_from":57},"W7212149653",[289,292,295,297,299,301],{"name":290,"orcid":291},"Abdalrahman Ahmed","https:\u002F\u002Forcid.org\u002F0009-0000-0624-2615",{"name":293,"orcid":294},"Kornél Czimber","https:\u002F\u002Forcid.org\u002F0000-0002-3739-2461",{"name":296,"orcid":9},"Saralees Nadarajah",{"name":298,"orcid":9},"Elmugheira Mockarram Ibrahim Mohammed",{"name":300,"orcid":9},"Ahmed Abdallah Adam Mohamed",{"name":302,"orcid":9},"Faisal Ismail Musa","https:\u002F\u002Flink.springer.com\u002Fcontent\u002Fpdf\u002F10.1007\u002Fs12665-026-13109-7.pdf",{"tldr":305,"method":306,"finding":307,"direction":55,"opportunity":308},"分析苏丹Jabel Marra地区1994–2024年植被变化及其气候驱动因素。","用Landsat NDVI、CHIRPS降水、MERRA-2温度和SPEI，结合","NDVI显著上升，与降水正相关、与温度负相关，2018年前多干旱后转湿。","冲突影响仅作背景，可结合社会经济与冲突数据量化其对干旱区植被恢复的独立贡献。","2026-09-13T23:30:24.709880Z"]
