Children’s beach monitoring in Ayangue tracked a drop in cigarette-butt litter
A study of the MCBAL citizen-science project in Ayangue, Ecuador, found that cigarette butts collected from monitored beach sand fell 53.2% between 2023 and 2024. Children aged 7 to 12 helped run monthly surveys, while reused-PVC collectors and a waste-for-sports-equipment exchange removed additional litter. The project was also incorporated into local community governance through the Cabildo.
