The Greater Accra region, stretching along the coast of Ghana from Cape Coast to Ada, is affected by floods every rainy season. The area is densely populated and low lying areas that are prone to floods are increasingly inhabited. The economy is fast growing, followed by rapid urban development. The existing drainage capacity is not sufficient anymore to safely discharge excess water and has even worsened due to siltation and solid waste piling up in the drains. High tides, the sea level rise and coastal erosion cause additional risks. The flood risk thus has increased rapidly, sadly demonstrated by the devastating flood of June 3rd 2015, causing a low lying gasoline station to explode, killing over 200 people.
The Government of Ghana, the municipalities of Greater Accra region and the World Bank are committed to reduce the vulnerability of the people, assets, livelihoods and economies to flood related risks. The World Bank therefore commissioned a consortium of Dutch firms HKV (lead partner) and Ecorys, together with Acon from Ghana, to support evidence based decision-making and investment planning for climate risk mitigation in Greater Accra, based upon objective assessment of the cities’ climate hazards, vulnerabilities and exposure. The strategy will provide guidance to decision makers on concrete climate adaptation investments within the Greater Accra region. The strategy will be developed in close interaction with the Ghanaian Stakeholders and will be completed by the end of 2017/early 2018.
