Ecorys prepares flood risk management plan for Greater Accra in Ghana

On behalf of the World Bank, a consortium with Ecorys will prepare a study and investment plan for flood management in Greater Accra (Ghana). The purpose of the study is to support evidence based decision-making and investment planning for climate risk mitigation in Greater Accra. More specifically, it will provide guidance and preparation of measures (until pre-feasibility level) for decision-makers in Ghana and World Bank regarding the most relevant flood risk management measures. Ecorys is part of a consortium with HKV Lijn in Water (lead) and Witteveen en Bos. The study and investment plan is scheduled from June 2017 until March 2018. 

Current situation
In June 2015, Accra was suffering from a devastating flood leading to a gas station inferno in which more than 200 people were killed. Preliminary assessment indicated that the gas station was built in a flood prone area, where it actually never should have been built. Increasing problems due to floods are a widely spread phenomenon in many African cities nowadays. Urban drainage systems are not adapted to the fast increasing population and an increase in paved area leads to higher peak discharges in heavy rainfall events. 
Ecorys will assess and prioritise flood protection measures, with support of multi-criteria and cost benefit analysis methods. Stakeholders from the relevant authorities in the project area will be engaged through meetings & interviews, discussions and workshops. 

This study aims at preparing no regret and implementable climate and disaster risk mitigation measures for the Greater Accra Metropolitan Area (GAMA). Based upon the findings from the research, the consortium will formulate investment strategies (programs) for the GAMA area and a pilot investment plan (at pre-feasibility level) for a pilot area (the Odaw river basin).
