| Title | Environmental Flood Risk Assessment and Urban Resilience Building: The Case Of Flooding In Tema, Ghana |
| Summary | Economic and social livelihoods in the past few decades have been greatly affected by flooding. This is mainly attributed to high-intensity rainfall as a result of climate change factors. However other studies have also pointed out that the incidence of flooding is greatly influenced by several human and environmental factors such as poor waste management, lack of coordination leading to poor development planning, poor drainage design problems, building of illegal structures in water courses and flood plains and rapid urbanization resulting from uninformed changes in land use patterns. In this study a catchment area close to the Sakumonor Ramsar site in the city of Tema was used as a case study as a result of its frequent flooding nature during high intensity rainfall. The aim of this study is to identify the environmental impact of flooding and help build flood resilience by performing an environmental flood risk assessment, make use of GIS data and Jacobs Flood Modeller 2021 software to predict future flood events. The results obtained shows a devastating impact of flooding on livelihoods and environment also future flood simulations indicates intense flooding event due to high rainfall and the inability of the Sakumono Ramsar site to contain much rainfall and channelling it to the sea. Based on these findings, it is suggested that, in order to find a long-term solution to flooding issues, the Government of Ghana must implement a more sustainable urban flood plain management system to be more resilient against future flooding events. |
