CLIMACCESS

Climate Change Resilience in Urban Mobility

The CLIMACCESS project presents a comprehensive research effort towards a better understanding of the links between climate change scenarios, urban accessibility and the mobility of urban residents in the Accra region.

Through an interdisciplinary approach, our team of Ghanaian and Danish partners investigates the physical and human factors that determine the impacts of climate change on mobility and accessibility, with the aim of developing strategies for increasing climate change resilience within urban mobility in the Ghanaian capital.
