This study evaluates the impact of LULC change on grazing resources in Dauchi Grazing Reserve, Song LGA, Adamawa State, Nigeria, using multi-temporal satellite imagery covering forty years. Satellite data were processed and classified using supervised classification techniques within a Geographic Information System (GIS) and remote sensing framework. Six LULC classes—grassland, shrubland, cropland, bare surface, built-up areas, and water body—were mapped and analysed to assess spatial and temporal transformations. Change detection analysis was employed to quantify transitions among land cover classes and assess implications for pasture availability. Results revealed a substantial decline in natural grazing resources, particularly grassland, which decreased from 32.77 km² (54.05%) in 1984 to 5.36 km² (8.84%) in 2024, representing a loss of 27.41 km². Conversely, cultivated land expanded considerably, increasing from 21.47 km² in 1984 to 46.35 km² in 2024. These changes reduced the availability and spatial continuity of natural grazing areas, potentially constraining forage availability and grazing capacity. The findings demonstrate that sustained LULC transformation has significantly altered the spatial distribution of grazing resources in Dauchi Grazing Reserve, creating challenges for sustainable livestock production and ecosystem resilience. The study recommends rangeland restoration, controlled grazing, integrated land-use planning, and protection of remaining natural vegetation to conserve grazing resources and support pastoral livelihoods.","土地利用与土地覆盖（LULC）变化是牧场退化的主要驱动因素，威胁着尼日利亚东北部几内亚和苏丹萨瓦纳生态系统的放牧资源和牧民生计。本研究利用覆盖四十年的多时相卫星影像，评估了尼日利亚阿达马瓦州松地方政府区道奇放牧保护区内土地利用与土地覆盖变化对放牧资源的影响。卫星数据在地理信息系统（GIS）和遥感框架内采用监督分类技术进行处理和分类。研究绘制并分析了六个土地利用与土地覆盖类别——草地、灌丛地、耕地、裸地、建设用地和水体——以评估其空间和时间变化。采用变化检测分析量化土地覆盖类别之间的转换，并评估其对牧草可利用性的影响。结果表明，天然放牧资源大幅减少，尤其是草地，从1984年的32.77平方公里（54.05%）下降至2024年的5.36平方公里（8.84%），减少了27.41平方公里。相反，耕地显著扩张，从1984年的21.47平方公里增加至2024年的46.35平方公里。这些变化减少了天然放牧区的可利用性和空间连续性，可能制约牧草供应和放牧承载力。研究结果表明，持续的土地利用与土地覆盖变化显著改变了道奇放牧保护区内放牧资源的空间分布，对可持续畜牧生产和生态系统恢复力构成了挑战。研究建议开展牧场恢复、实施控制性放牧、进行综合土地利用规划，并保护剩余天然植被，以保育放牧资源并支持牧民生计。",null,"FUDMA Journal of Sciences","2026-09-28T00:00:00Z","论文",10,false,65,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},8,20,16,12,9,1,"基于四十年多时相遥感的牧区草地退化实证研究，数据扎实但属区域案例，对国内农业信息化参考价值有限。",[25],{"name":10,"url":6},[27,28,29,30,31],"遥感监测","土地利用","尼日利亚","农牧交错带","草地退化",{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},"I4","gis","GIS与空间分析","\u002Ftopic\u002Fdigital-agriculture\u002Fgis","I",[],{"status":40,"locked":14,"version":41,"method":42,"evidence":43},"classified","2026-10-22.2","rules",{"candidates":44,"agricultural_evidence":46},[45,53,61,69,76],{"code":33,"score":21,"supported":46,"title":47,"abstract":48,"tags":52},true,[],[49,50,51],"地理信息","GIS","geographic information",[],{"code":54,"score":55,"supported":46,"title":56,"abstract":57,"tags":60},"I3",7,[],[58,59],"遥感","remote sensing",[27],{"code":62,"score":63,"supported":46,"title":64,"abstract":65,"tags":68},"C",6,[],[66,67],"畜牧","livestock",[],{"code":70,"score":71,"supported":46,"title":72,"abstract":73,"tags":75},"C4",3,[],[74],"forage",[],{"code":77,"score":22,"supported":14,"title":78,"abstract":79,"tags":80},"H6",[],[],[28],[82,83],"Dauchi 放牧保护区 土地利用","Adamawa 草地退化 遥感","Dauchi放牧保护区土地利用-3849",2,"10.33003\u002Ffjs-2026-1018-6083",{"doi":86,"openalex_id":88,"authors":89,"venue":10,"cited_by_count":96,"oa_url":97,"card":98,"direction":102,"ingested_from":104},"W7214627198",[90,92,94],{"name":91,"orcid":9},"Nagarta Jamala Gailyson",{"name":93,"orcid":9},"Andrew Egba Ubogu",{"name":95,"orcid":9},"Yaro Abdu",0,"https:\u002F\u002Ffjs.fudutsinma.edu.ng\u002Findex.php\u002Ffjs\u002Farticle\u002Fdownload\u002F6083\u002F3992",{"tldr":99,"method":100,"finding":101,"direction":102,"opportunity":103},"用40年遥感影像评估尼日利亚Dauchi放牧保护区土地利用变化对放牧资源的影响。","多时相卫星影像监督分类与GIS变化检测，划分六类地物。","草地从54.05%降至8.84%，耕地大幅扩张，放牧资源显著萎缩。","农业遥感与作物表型","可结合多源遥感与牧草生产力模型，量化放牧承载力并预警退化风险。","openalex","2026-09-30T23:30:31.022343Z",{"total":63,"page":22,"page_size":63,"items":107},[108,176,235,298,369,440],{"id":109,"title":110,"url":111,"summary":112,"summary_zh":113,"content":9,"source_name":114,"source_url":111,"published_at":115,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":96,"score_detail":116,"sources":118,"tags":120,"primary_topic":123,"secondary_topics":128,"classification":130,"search_phrases":153,"slug":156,"view_count":96,"doi":157,"paper":158,"created_at":175},5485,"Integrating machine learning and geospatial technologies for spatio-temporal analysis of urban expansion and land use transformation in Gambella Town, Ethiopia","https:\u002F\u002Fdoi.org\u002F10.1371\u002Fjournal.pone.0360419","Rapid urbanization and the associated expansion of built-up areas are transforming land resources, ecosystem functions, and the spatial structure of cities. Distinguishing urban growth, urban expansion, and urban sprawl is essential for understanding the processes and patterns of urban transformation and supporting sustainable urban planning. This study integrates machine learning and geospatial technologies to analyze spatio-temporal land use and land cover (LULC) dynamics and urban expansion in Gambella Town, Ethiopia. Multi-temporal Landsat satellite images from 2005, 2015, and 2025 were processed using remote sensing techniques and a supervised machine learning approach based on the Random Forest (RF) classifier. Six major LULC classes were identified: Agricultural Land, Bush with Grass, Built-Up Area, Bare Land, Forest Land, and Water Bodies. The classification achieved overall accuracies of 90%, 90%, and 89% for 2005, 2015, and 2025, respectively. The results revealed substantial land transformation and rapid physical urban expansion, with the built-up area increasing from 93 ha (2.0%) in 2005–1,956 ha (41.3%) in 2025. This expansion was accompanied by major transformations of surrounding land resources, particularly the conversion of Bush with Grass and other open areas to built-up land. Agricultural land increased from 634 ha (13.4%) to 1,750 ha (36.9%), whereas Bush with Grass declined from 3,375 ha (71.1%) to 652 ha (13.7%). Socio-economic information collected from 277 respondents indicated that population growth, rural–urban migration, housing demand, employment opportunities, and infrastructure development were major drivers of urban expansion. The study distinguishes urban expansion, represented by the increase in built-up land, from urban sprawl, which refers to the spatial pattern and form of outward urban development. The integration of Random Forest classification and GIS-based spatial analysis provides valuable evidence of land transformation, vegetation loss, and increasing pressure on urban services, supporting more sustainable urban planning and land management in Gambella Town.","快速城市化及与之相关的建成区扩张正在改变土地资源、生态系统功能和城市空间结构。区分城市增长（urban growth）、城市扩张（urban expansion）和城市蔓延（urban sprawl），对于理解城市转型的过程与格局、支撑可持续城市规划至关重要。本研究融合机器学习与地理空间技术，分析埃塞俄比亚甘贝拉镇（Gambella Town）土地利用与土地覆盖（LULC）的时空动态及城市扩张。采用遥感技术和基于随机森林（RF）分类器的监督机器学习方法，处理了2005年、2015年和2025年的多时相Landsat卫星影像。研究识别出六类主要LULC类型：农业用地、灌草地、建成区、裸地、林地和水体。2005年、2015年和2025年的分类总体精度分别为90%、90%和89%。结果表明，土地发生了显著转变，城市实体空间快速扩张，建成区面积从2005年的93公顷（2.0%）增至2025年的1,956公顷（41.3%）。这一扩张伴随着周边土地资源的重大转变，尤其是灌草地及其他开阔地被转化为建成用地。农业用地从634公顷（13.4%）增至1,750公顷（36.9%），而灌草地则从3,375公顷（71.1%）降至652公顷（13.7%）。从277名受访者收集的社会经济信息表明，人口增长、城乡迁移、住房需求、就业机会和基础设施建设是城市扩张的主要驱动因素。本研究将城市扩张（以建成用地增加为表征）与城市蔓延（指城市向外发展的空间格局与形态）加以区分。随机森林分类与基于GIS的空间分析的融合，为土地转变、植被丧失及城市服务压力加剧提供了有价值的证据，有助于甘贝拉镇实现更可持续的城市规划与土地管理。","PLoS ONE","2026-10-20T00:00:00Z",{"impact":96,"substance":96,"depth":96,"authority":96,"freshness":96,"relevant":96,"comment":117},"研究聚焦埃塞俄比亚城市扩张与土地利用变化，属城市地理与遥感应用，与三农、农业信息化主题无直接关联，不建议进入每日精选。",[119],{"name":114,"url":111},[121,27,28,122],"机器学习","城市扩张",{"code":124,"slug":125,"name":126,"path":127,"parent_code":37},"I2","agricultural-ai","农业AI与大模型","\u002Ftopic\u002Fdigital-agriculture\u002Fagricultural-ai",[129],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":131},{"candidates":132,"agricultural_evidence":46},[133,139,145,149],{"code":124,"score":134,"supported":46,"title":135,"abstract":137,"tags":138},15,[136],"machine learning",[121,136],[121],{"code":33,"score":21,"supported":46,"title":140,"abstract":141,"tags":144},[],[142,50,143],"空间分析","spatial analysis",[],{"code":54,"score":55,"supported":46,"title":146,"abstract":147,"tags":148},[],[58,59],[27],{"code":77,"score":22,"supported":14,"title":150,"abstract":151,"tags":152},[],[],[28],[154,155],"Gambella Town 城市扩张","Random Forest 土地利用分类","GambellaTown城市扩张-5485","10.1371\u002Fjournal.pone.0360419",{"doi":157,"openalex_id":159,"authors":160,"venue":114,"cited_by_count":96,"oa_url":111,"card":170,"direction":102,"ingested_from":104},"W7223022155",[161,164,166,168],{"name":162,"orcid":163},"Kanenus Fufa Dararo","https:\u002F\u002Forcid.org\u002F0009-0007-5747-1558",{"name":165,"orcid":9},"Goanar Jal Dup",{"name":167,"orcid":9},"Weyesa Merga Chemeda",{"name":169,"orcid":9},"Shankar Karuppannan",{"tldr":171,"method":172,"finding":173,"direction":102,"opportunity":174},"用机器学习与遥感分析埃塞俄比亚甘贝拉镇2005-2025年城市扩张与土地利用变化。","Landsat多时相影像、随机森林分类与GIS空间分析，结合277份问卷。","建成区从93公顷增至1956公顷，灌草地大幅转为建成区和农地。","可将随机森林时序分类与驱动力调查结合，扩展到更多非洲小城镇并耦合城市增长模拟。","2026-10-21T23:30:23.271293Z",{"id":177,"title":178,"url":179,"summary":180,"summary_zh":181,"content":9,"source_name":182,"source_url":179,"published_at":183,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":184,"score_detail":185,"sources":189,"tags":191,"primary_topic":194,"secondary_topics":195,"classification":196,"search_phrases":211,"slug":214,"view_count":96,"doi":215,"paper":216,"created_at":234},5323,"Impact of Land Use and Land Cover Change on Vegetation Cover Loss in Rwanda: Evidence from Muhoza Sector, Musanze District (2015–2025)","https:\u002F\u002Fdoi.org\u002F10.38124\u002Fijisrt\u002F26oct696","This study analyzed the impact of land use and land cover (LULC) change on vegetation cover loss in Muhoza Sector, Musanze District, Rwanda, between 2015 and 2025.

Wasteland remained the dominant land-cover category but declined from 779.07 km² (78.28%) in 2017 to 726.86 km² (71.41%) in 2024. Agricultural area grew by 86.62 km² (+19.48% to 280.52 km²), adding 94.76 km² of wasteland. Gradual settlement and infrastructure development also resulted in an increase in built-up area from 3.89 km2 to 7.73 km2 . The water bodies were small in spatial extent and slight shifts happened between bare ground and other land-cover classes. The results clearly show that the Sentinel-2 data and GIS-based analysis is useful in monitoring LULC dynamics in data-sparse arid regions. The present extent of agriculture and development has occurred at a time when there is a need to manage the land and groundwater resources sustainably, monitor environment, and plan land use with climate change in Phalsoond tehsil of Jaisalmer District in western Rajasthan.","土地利用与土地覆盖（LULC）变化分析是环境变化、资源利用和可持续发展的重要指标，在土地与水资源极为脆弱的干旱地区尤为如此。本研究利用遥感与地理信息系统（GIS）技术，对印度拉贾斯坦邦杰伊瑟尔梅尔县Phascoond乡2017年至2024年间的LULC变化进行了时空分析。为对研究区进行分类，采用了Esri Sentinel-2土地覆盖浏览器提供的10 m空间分辨率多时相Sentinel-2数据，将区域划分为五个类别，即水体、农用地、建设用地、裸地和荒地。通过分类后比较和基于GIS的变化检测技术，从幅度和方向两方面对LULC变化进行了量化。研究结果表明，2017年至2024年间景观发生了显著变化。荒地仍为优势土地覆盖类型，但从2017年的779.07 km²（78.28%）下降至2024年的726.86 km²（71.41%）。农业面积增加了86.62 km²（增幅19.48%，达到280.52 km²），占用了94.76 km²的荒地。逐步的聚落与基础设施建设也导致建设用地从3.89 km²增加至7.73 km²。水体空间范围较小，裸地与其他土地覆盖类别之间发生了轻微转换。结果清楚表明，Sentinel-2数据与基于GIS的分析对于监测数据稀缺干旱地区的LULC动态具有实用价值。当前农业与开发的程度出现在这样一个时期：拉贾斯坦邦西部杰伊瑟尔梅尔县Phalsoond乡亟需可持续管理土地与地下水资源、监测环境，并在气候变化背景下进行土地利用规划。","International Journal for Research in Applied Science and Engineering Technology","2026-09-30T00:00:00Z",52,{"impact":63,"substance":186,"depth":187,"authority":63,"freshness":17,"relevant":22,"comment":308},"基于Sentinel-2与GIS的印度干旱区土地利用变化研究，方法规范但属区域性案例，对国内三农信息化参考价值有限。",[310],{"name":304,"url":301},[27,28,312,313],"干旱区农业","GIS应用",{"code":315,"slug":316,"name":317,"path":318,"parent_code":319},"H7","climate","气候适应与防灾减灾","\u002Ftopic\u002Fenvironment\u002Fclimate","H",[321],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":323},{"candidates":324,"agricultural_evidence":46},[325,332,336,340,346],{"code":315,"score":13,"supported":46,"title":326,"abstract":327,"tags":331},[],[328,329,330],"气候变化","干旱","climate change",[312],{"code":33,"score":21,"supported":46,"title":333,"abstract":334,"tags":335},[],[49,50,51],[],{"code":54,"score":55,"supported":46,"title":337,"abstract":338,"tags":339},[],[58,59],[27],{"code":341,"score":71,"supported":46,"title":342,"abstract":343,"tags":345},"H3",[],[344],"水资源",[],{"code":77,"score":22,"supported":14,"title":347,"abstract":348,"tags":349},[],[],[28],[351,352],"Jaisalmer 土地利用变化","Sentinel-2 遥感 干旱区","Jaisalmer土地利用变化-3903","10.22214\u002Fijraset.2026.84983",{"doi":354,"openalex_id":356,"authors":357,"venue":304,"cited_by_count":96,"oa_url":301,"card":363,"direction":102,"ingested_from":104},"W7214996325",[358,360],{"name":359,"orcid":9},"Deendayal .",{"name":361,"orcid":362},"Om Prakash","https:\u002F\u002Forcid.org\u002F0000-0003-1239-445X",{"tldr":364,"method":365,"finding":366,"direction":102,"opportunity":367},"基于Sentinel-2和GIS分析印度拉贾斯坦邦干旱区2017-2024年土地利用\u002F覆盖变化。","Sentinel-2 10m影像与GIS分类，采用分类后比较法检测LULC变化。","荒地减少52.21 km²，农业增加86.62 km²，建设用地翻倍，水资源面积小。","可结合多源遥感与机器学习，在数据稀疏干旱区开展高精度LULC动态监测与驱动机制研究。","2026-10-01T23:30:29.277138Z",{"id":370,"title":371,"url":372,"summary":373,"summary_zh":374,"content":9,"source_name":375,"source_url":376,"published_at":377,"category":12,"cover_url":9,"hotness":13,"is_selected":14,"score":378,"score_detail":379,"sources":381,"tags":383,"primary_topic":386,"secondary_topics":390,"classification":392,"search_phrases":420,"slug":423,"view_count":424,"doi":425,"paper":426,"created_at":439},3187,"Spatio-temporal analysis of Land Use and Land Cover (LULC) change using high resolution satellite data: A case study of Nagaon, Assam","https:\u002F\u002Fdoi.org\u002F10.31018\u002Fjans.v18i3.7774","Geographic information systems (GIS) coupled with satellite remote sensing (RS) have had a significant impact on the assessment and mapping of land surface dynamics, specifically the analysis of land-use land-cover (LULC) change.

An interactive analytical approach was adopted to examine the transitions among built-up areas, cropland, and bare land throughout the urbanization process. Remote Sensing and GIS techniques, in conjunction with the Land Transfer Matrix (LTM), Landscape Metrics (LM), Multi-buffer Ring (MBR) and complementary spatial tools, were employed to analyze the city of Tiaret in Algeria over the past half century (1972-2022). The results reveal a marked intensification of urbanization, with an Overall Average Annual Urban Expansion Rate (OA-AUER) of 28.3 ha and a concurrent rise in bare land driven by cropland conversion under urban pressure. Notably, 89.4 % of cropland loss initially transitions into bare land, while subsequent urban development originates from cropland (52 %) and bare land (47 %). The observed density patterns in peripheral areas confirm the significant influence of the urban core on surrounding land-cover transformations. These findings elucidate the urbanization process while considering the transitional role of bare land and further explain diffusion coalescence process. Further empirical research is recommended to refine theoretical frameworks on landscape transformation dynamics and to inform policies aimed at mitigating bare-land expansion in peri-urban areas, controlling cropland urbanization, and planning sustainable urban growth.","摘要 本研究探讨城市扩张如何影响土地覆盖动态。采用交互式分析方法，考察城市化进程中建成区、耕地和裸地之间的转换。运用遥感与地理信息系统技术，结合土地转移矩阵（LTM）、景观格局指数（LM）、多缓冲环（MBR）及辅助空间工具，对阿尔及利亚提亚雷特市过去半个世纪（1972—2022年）的变化进行了分析。结果表明，城市化显著加剧，年均城市扩张总面积率（OA-AUER）为28.3公顷，同时在城市压力下耕地转换导致裸地同步增加。值得注意的是，89.4%的耕地损失最初转变为裸地，而随后的城市发展来源于耕地（52%）和裸地（47%）。外围区域观测到的密度格局证实了城市核心对周边土地覆盖变化的显著影响。这些发现阐明了城市化过程，同时考虑了裸地的过渡性作用，并进一步解释了扩散聚合过程。建议开展进一步实证研究，以完善景观转型动态的理论框架，并为旨在减缓城郊地区裸地扩张、控制耕地城市化以及规划可持续城市增长的政策提供依据。","Journal of Landscape Ecology","2026-09-19T00:00:00Z",{"impact":96,"substance":96,"depth":96,"authority":96,"freshness":96,"relevant":96,"comment":449},"该论文聚焦阿尔及利亚Tiaret市城市扩张与土地覆盖变化，属城市地理与遥感应用研究，与三农、农业信息化、智慧农业主题无直接关联，不建议进入每日精选。",[451],{"name":446,"url":443},[453,27,28,122],"耕地保护",{"code":54,"slug":387,"name":388,"path":389,"parent_code":37},[456],{"code":33,"slug":34,"name":35,"path":36,"parent_code":37},{"status":40,"locked":14,"version":41,"method":42,"evidence":458},{"candidates":459,"agricultural_evidence":46},[460,464,468,474,479],{"code":54,"score":134,"supported":46,"title":461,"abstract":462,"tags":463},[59],[58,59],[27],{"code":33,"score":187,"supported":46,"title":465,"abstract":466,"tags":467},[50],[49,50],[],{"code":469,"score":71,"supported":46,"title":470,"abstract":471,"tags":473},"G2",[],[472],"land transfer",[],{"code":475,"score":22,"supported":14,"title":476,"abstract":477,"tags":478},"H1",[],[],[453],{"code":77,"score":22,"supported":14,"title":480,"abstract":481,"tags":482},[],[],[28],[484,485],"Tiaret 城市扩张 遥感","耕地 建设用地 转移矩阵","Tiaret城市扩张遥感-3071","10.2478\u002Fjlecol-2026-0038",{"doi":487,"openalex_id":489,"authors":490,"venue":446,"cited_by_count":96,"oa_url":498,"card":499,"direction":102,"ingested_from":104},"W7213652939",[491,493,495],{"name":492,"orcid":9},"Amina Kalbaza",{"name":494,"orcid":9},"Belkacem Marir",{"name":496,"orcid":497},"Farida Naceur","https:\u002F\u002Forcid.org\u002F0009-0004-1962-4937","https:\u002F\u002Freference-global.com\u002Fdownload\u002Farticle\u002F10.2478\u002Fjlecol-2026-0038.pdf",{"tldr":500,"method":501,"finding":502,"direction":102,"opportunity":503},"基于遥感与GIS分析阿尔及利亚提亚雷特1972—2022年城市扩张对景观与土地覆盖的影响。","遥感、GIS、土地转移矩阵、景观格局指数与多缓冲环分析。","耕地先转为裸地再被城市占用，城市核心显著驱动外围土地覆盖转变。","可延伸研究裸地作为耕地—城市转换中间态的机制，并构建城郊耕地流失预警模型。","2026-09-21T23:30:24.332177Z"]
