Accra floods driven more by poor drainage and silt than littering — Dr Ohemeng-Ntiamoah

"If you pay careful attention to the drains and what is choking them, you realise that it is silt primarily, before even waste.

She noted that the large volumes of silt removed during dredging operations in the Odaw River demonstrate the scale of the problem and argued that efforts to reduce erosion should receive as much attention as waste management.

She also disputed the widely held belief that plastic waste is the main material clogging the city's drains, explaining that silt is the dominant obstruction.
