Cities in sub-Saharan Africa are undergoing dynamic transformation processes and face a series of challenges. The CHIDA project is investigating these challenges using the nature-based solutions (NbS) approach. The international project consortium focuses on the interrelationships between NbS (especially urban green infrastructure - GI), civic engagement, livelihoods and food security. The project uses the example of four cities in Malawi and South Africa to investigate the resulting potential to effectively counter the threats and risks of urban living environments.
