Enabling Policy Environment: Exposure Analysis and Modelling

Ghana’s capital Accra is a significant business hub and has a high natural vulnerability to flooding. A combination of unplanned spatial developments, high percentage of paved areas, lack of proper solid waste management, and lack of maintenance for the drainage system result in frequent flooding during (but sometimes even outside) the rainy season. It is expected that climate change further aggravates this.

Metropolitan, Municipal and District Assemblies (MMDAs) in the Greater Accra Metropolitan Area (GAMA) face significant challenges to finance reconstruction work after floods. The negative impact and damage caused by flooding in cities demand a robust Integrated Disaster Risk Management (IDRM) approach which also considers sustainable risk transfer measures. Therefore, a risk transfer solution, such as insurance, as part of an IDRM could help speed up reconstruction through the swift disbursement of claim pay-outs after an event. To this end, the Public-Private Partnership between Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH and Allianz Reinsurance implemented the project “Developing Risk Management Approaches for Climate Risk”. Within an integrated flood risk management approach, the project focused on preparing the grounds to insure public assets against flood.
