The paper presents an open‑access deep learning model that automatically detects openly dumped municipal solid waste using crowdsourced UAV imagery across 29 regions in 10 Sub‑Saharan African countries. Trained on manually annotated image tiles, the model shows excellent performance and reveals heterogeneous waste accumulation patterns, from localized hotspots along waterways to dispersed litter in urban areas. The study links waste accumulation most strongly to population density and lack of local infrastructure, underscoring the need for fine‑scale data to understand localized waste dynamics.
