Grey to Blue Waters: Enhancing Marine Water Quality in Zanzibar

The Nairobi Convention, through the ACP MEAs 3 programme, is working with the Zanzibar Fisheries Research and Marine Resources Institute (ZAFIRI) to assess the marine water quality in Zanzibar and establish a monitoring program. This monitoring is essential for the successful implementation of Zanzibar’s Blue Economy Policy.

Marine water pollution is a global issue that threatens the health of oceans and ecosystems, including Zanzibar. The growing number of tourism hotels, coastal developments, and other human activities have led to significant pollution and degradation of the coastal waters of Zanzibar. This pollution, caused by various pollutants such as organic toxins, metals, microorganisms, and plastics, not only harms marine life but also affects human activities like recreation, fishing, and aquaculture. As Zanzibar embraces the blue economy, it is crucial to control and monitor marine water pollution.

The project involves examining the physio-chemical and biological parameters of coastal water, assessing the level of marine litter, and mapping potential land-based sources of pollution. By establishing a monitoring system, Zanzibar can effectively control pollution and ensure the success of its coastal economic options, such as tourism, fisheries, and mariculture. The outcomes of this project will also support the improvement of fisheries and aquaculture sectors, tourism, and ocean governance through marine conservation. Additionally, it will contribute to the development of regional standards for marine water quality in the Western Indian Ocean region.
