WIOMSA Marine Litter Monitoring Project

WIOMSA Marine Litter Monitoring Project

Western Indian Ocean Marine Science Association

Litter found in waterways, along the coast, and in the ocean has widely cited ecological, economic and social repercussions.

In the Western Indian Ocean (WIO) region, major African cities and towns are already producing large amounts of litter that eventually ends up in the ocean. This amount of litter is only expected to increase as Africa’s population continues to grow.

To combat the litter crisis, many African countries have signed international treaties regarding the regulation and reduction of marine litter. However, in order to achieve these goals, we need to first determine the current amount and types of litter flowing down rivers and washing up on shores in WIO countries.

This information is currently lacking in most of the countries in the WIO region. Marine litter monitoring initiatives are therefore needed to make important management decisions in WIO countries as we try to lower the amount of litter in the region. The effectiveness of such interventions can then be tested by long-term monitoring of marine litter.

To enable the countries of the Western Indian Ocean to become leaders in litter management, the Western Indian Ocean Marine Science Association (WIOMSA) is partnering with Sustainable Seas Trust (SST) through its African Marine Waste Network (AMWN) project to initiate an observation and monitoring programme for marine litter in Kenya, Madagascar, Mauritius, Mozambique, Seychelles, South Africa and Tanzania. This programme is scheduled to run from 2019-2021 and focuses on developing monitoring programmes mainly for land-based sources of litter.
