This report on the WIOMSA Marine Litter Monitoring Programme is co-authored by WIOMSA and SST. The landmark publication brings together five years of coordinated regional monitoring across seven countries — building harmonised data, community ownership, and scientific tools like the African Litter Monitoring Manual. From schools to policymakers, the programme has shown how evidence can drive action, strengthen regional collaboration, and support global commitments such as the UN Plastics Treaty.
