Reality Check Workshop: Accra, Ghana

The Greater Accra Metropolitan Area (GAMA) in Ghana is in the Greater Accra Region which also hosts the capital, Accra. GAMA occupies 3,245 square km and stretching 225 km along the Gulf of Guinea in the Atlantic Ocean. It comprises of 16 metropolitan, municipal and district assemblies. The GAMA has a population of 4.4 million, representing 17.7% of Ghana’s entire population and one of the fastest growing in the African subregion of West Africa, growing between 3.5 and 3.9 percent annually.

Ghana’s national communications to the UNFCCC suggest increasing intensities and frequencies of precipitation because of climate change and rains received within protracted time periods with delayed onsets. Urban areas have been most affected and the GAMA has continuously experienced floods annually in the past decade, and projected to intensify in the coming years. The GAMA falls within the catchments of the highly deforested and degraded Akwapim mountain range, becoming receptacle for increased runoff water down the slopes. Rapid urbanisation, rural-urban migration, informal settlements, and infrastructure are striking features caused mostly by inadequate planning, housing deficits and limited basic infrastructure and services. The already inadequate land and natural spaces in GAMA have dwindled significantly from the expanded infrastructure and in most cases sealing land surfaces that tend to reduce water infiltration in heavily built areas which have resulted in increased exposure and floods.

Multiplicity of adaptation measures include strengthening of institutions, encompassing appraisal of infrastructure building codes, upgrading of slum areas and informal settlements, climate risk and early warning, human resource capacity building, use of ICT and enhanced awareness. The IDRC’s Cities and Climate Change project at the Regional Institute for Population Studies (RIPS), University of Ghana is seeking to develop climate smart integrated flood management framework based on socio-demographic change and climate induced flood risks in the GAMA. Thus, the project will complement actions on the ground by providing options that harmonize such actions to manage floods.
