This research investigates the relationship between urbanization as a land use/land cover change and the increased flood disasters in Accra. Understanding this relationship will provide evidence for urban development planners, policy makers and flood managers to coordinate in responding to the problems effectively. This study maps and analyzes the changes in urbanization from 1991 to 2015. The research reviews the trends of flood events in Greater Accra and analyzes the relationship between the pattern of urbanization and the increase in flood disaster events from 1991 to 2015. The research revealed that there was an increase in urban land use/land cover change of up to 95.51% and 129.14% in the periods 1991-2002 and 2002-2015 respectively. The pattern of urbanization took place in an unplanned style, where physical developments in waterways became high. The findings show that the pattern of flood disasters increased from 1991 to 2015 with evidence showing two years having repeated flood events.
本研究调查了城市化作为土地利用/土地覆被变化与阿克拉洪水灾害增加之间的关系。了解这种关系将为城市发展规划者、政策制定者和洪水管理者提供证据,以便他们有效地协调应对这些问题。本研究绘制并分析了 1991 年至 2015 年期间的城市化变化。研究回顾了大阿克拉地区洪水事件的趋势,并分析了城市化模式与 1991 年至 2015 年洪水灾害增加之间的关系。研究表明,在 1991-2002 年和 2002-2015 年期间,城市土地利用/土地覆被变化分别增加了 95.51%和 129.14%。城市化模式是无规划的,水道中的实体发展变得很突出。研究结果表明,1991 年至 2015 年期间,洪水灾害模式有所增加,有证据表明有两年发生了重复的洪水事件。
