The findings reveal substantial land use\u002Fland cover transformations, particularly the decline in forest cover and agricultural land, and a significant increase in built-up areas. NDVI analysis confirmed a notable reduction in vegetation due to infrastructural development. Population and economic growth emerged as the dominant drivers of urban expansion, corroborated by weighted average analysis, while secondary factors such as infrastructure and policy also contributed. Farmland loss was and land use transformations was identified as the most critical impact, underscoring threats to food security and ecosystem services. The spatial pattern of urbanization followed a concentric model driven by road infrastructure and socio-economic dynamics, with pronounced growth in southeastern Uyo and surrounding LGAs. Future projections using the MOLLUSC model suggest that by 2050, built-up areas will increase by 79%, with corresponding declines in agricultural land, forests, and water bodies. These findings call for proactive, sustainable land-use strategies and integrated urban planning to address the challenges posed by rapid urbanization, ensuring ecological sustainability, socio economic equity, and spatial resilience in Uyo Capital City and similar urbanizing regions.","本研究综合运用遥感、地理信息系统（GIS）和社会经济分析，对1986年至2024年间乌约首府城市的城市扩张进行了全面评估。研究结果揭示了土地利用\u002F土地覆盖的显著变化，尤其是森林覆盖和农业用地的减少，以及建成区面积的大幅增加。归一化植被指数（NDVI）分析证实，基础设施建设导致植被明显减少。人口和经济增长成为城市扩张的主要驱动力，加权平均分析对此予以佐证，而基础设施和政策等次要因素亦有所贡献。农田流失和土地利用转型被确定为最突出的影响，凸显了对粮食安全和生态系统服务的威胁。城市化空间格局遵循以道路基础设施和社会经济动态为驱动的同心圆模式，乌约东南部及周边地方政府区域增长尤为显著。基于MOLLUSC模型的未来预测表明，到2050年，建成区面积将增加79%，农业用地、森林和水体相应减少。这些发现呼吁采取积极主动的可持续土地利用策略和综合城市规划，以应对快速城市化带来的挑战，确保乌约首府城市及类似城市化地区的生态可持续性、社会经济公平和空间韧性。",null,"IIARD INTERNATIONAL JOURNAL OF GEOGRAPHY AND ENVIRONMENTAL MANAGEMENT","2026-09-10T00:00:00Z","论文",10,false,0,{"impact":15,"substance":15,"depth":15,"authority":15,"freshness":15,"relevant":15,"comment":17},"研究尼日利亚乌约市城市扩张与农地流失，属城市地理与遥感领域，与三农、农业信息化主题关联薄弱，不建议进入每日精选。",[19],{"name":10,"url":6},[21,22,23],"遥感监测","土地利用","城市化","10.56201\u002Fijgem.vol.12.no3.2026.pg117.137",{"doi":24,"openalex_id":26,"authors":27,"venue":10,"cited_by_count":15,"oa_url":9,"card":30,"direction":34,"ingested_from":36},"W7212186540",[28],{"name":29,"orcid":9},"D.
