Our team aims to establish Zanzibar’s first open monitoring network for fine air pollution (PM2.5) by installing 20 monitoring devices across Unguja and Pemba. These devices will generate reliable and timely information that can help the government and people to better understand and manage air quality. The project intends to (i) produce Zanzibar’s first report on the state of air quality, which will provide information for inclusion in the wider National State of Environment Report, which has previously lacked information on air pollution. (ii) improve how air quality information is collected, reported, and shared with the public, including tourists, by combining information from monitoring devices on the ground with satellite information. (iii) contribute to the domiciling of air quality regulations for Zanzibar by preparing the white paper. Through this, it will inform the inclusion of air quality provisions in the revised Zanzibar Environmental Policy. Overall, the project intends to strengthen the ability of Zanzibar Environmental Management Authority to continue monitoring air quality and provide information needed to help protect the health and well-being of people in Zanzibar.

Our team aims to establish Zanzibar’s first open PM2.5 monitoring network to generate trusted, real‑time evidence that strengthens national environmental governance. Over the project duration, we will deploy 20 monitors across Unguja and Pemba, openly publish ready-to-use data, and translate findings into actionable policy-level and national goals. These goals include (i) developing the first national state of air quality report (ii) grounding satellite estimates with reliable local measurements for public information sharing (iii) a white paper that will inform the domicile air quality regulation for Zanzibar and enhance enforcement capacity. Ultimately, we aim to empower the Zanzibar Environmental Management Authority to sustain long‑term air quality monitoring and protect public health.
