The river gets cleaned up occasionally by many groups, but almost no one logs what was collected, from where, and when. That missing data is exactly what municipal planners, NGOs, and researchers need in order to argue for upstream interventions. We run monthly cleanups, but the real contribution is the open log — waste type, weight, GPS, photos — published after every session.
Quarterly sweep confirms the log is current, the dataset is growing, and two external researchers have started citing it. No action required.
