Sierra Leone is highly exposed to the impacts of climate change, particularly in rapidly growing urban areas such as Freetown. During the rainy season, blocked drainage systems and polluted waterways contribute to frequent flooding, damaging homes, disrupting access to essential services, and increasing the risk of disease outbreaks.
The goal: Develop a solution that continuously engages local communities in running river-waste collection initiatives and strengthens resilience to flooding.
