Ose Ifa Residency Is a community-led monitoring and knowledge-sharing residency. Five young Ifa/Osun priests were trained to document environmental changes in the river with mobile phones. Monitoring occurred every five days in alignment with Ose, the five-day ritual cycle in Ifa practice, during which participants visit the river for worship. Observations of the river are archived in a shared drive, forming a visual timeline of environmental change.
