Contested causes of flooding in poor urban areas in Accra, Ghana: an actor-oriented perspective

It is well known that urbanisation and climate change are likely to induce more floods in existing flood-prone African cities. Previous contributions on the causes of flooding in urban areas mostly do not consider the actors involved in adaptation and do not acknowledge the diversity of knowledge they possess. In this study, the causes of urban floods in an African city are explored from an actor-oriented perspective. The Kendall coefficient of concordance method is used to analyse interviews with household members and community leaders living in flood-prone communities as well as technocrats involved in public flood adaptation at the metropolitan level. The level of agreement on the causes of flooding is low among the actors, making the case for integrating informal actors into the formal flood adaptation structures at the metropolitan level. This will harness the diversity of knowledge on how flood risk unfolds for the purpose of local adaptation to urban floods in African cities.
