From Zanzibar to Kilwa Masoko to Mafia Island, Tanzania is famous for its beautiful beaches and rich biodiversity, including coral reefs, sea turtles, dugongs and more. Yet, as elsewhere, these coastal idylls are under threat from the effects of climate change, illegal fishing, and other dangers.
In an effort to protect these paradises, Tanzania has declared 18 marine conservation (or protection) areas (MCAs or MPAs) on the mainland and an additional nine on Zanzibar. An MCA is an area of ocean or coastline that has been specially designated for protection for the benefit of nature and people. A well-managed MCA can bring significant economic, social, and environmental benefits to a country, by preventing overexploitation of fish stocks, safeguarding or creating jobs in the tourism and fisheries sectors, and halting biodiversity loss.
One such MCA is the Pemba Channel Conservation Area (PECCA), declared in 2005 and home to coral reefs (among the most diverse in East Africa), important turtle nesting grounds, seabird habitats, mangroves, and rich marine biodiversity. The PECCA MCA is jointly managed by Zanzibar’s Department of Fisheries Development (DoFD) and the community. Nevertheless, the MCA faces some key challenges, including persistent illegal and destructive fishing (and a lack of alternative livelihoods to reduce pressure on fish stocks), a lack of coordination between the public sector, businesses, and communities living near the MCA, inadequate community participation in conservation and planning initiatives, etc.

A community that is empowered to take on these management challenges could help ensure a better functioning MCA. A new demonstration project, led by Zanzibar’s Department of Environment, aims to help communities lead in the sustainable management of small-scale fisheries in the PECCA MCA by using an ecosystem-based management (EBM) approach. EBM is an “integrated management approach that recognizes the full array of interactions within an ecosystem, including humans, rather than considering single issues, species, or ecosystem services in isolation.”
As such, this project will address many of the issues that have culminated in threats to the MCA. Firstly, project proponents will develop an integrated fisheries management plan to conserve, manage, and monitor marine biodiversity. New guidelines for community fishery closure zones – i.e., areas in which fishing will be off-limits to help fish stocks naturally rebound – will be created. Meanwhile, community-led fishery patrols – who monitor whether any illegal and destructive fishing practices are occurring – as well as enforcement measures will be strengthened.
Additionally, alternative livelihood opportunities, which will help reduce the number of fishers combing the MCA and therefore pressure on fish stocks, will be introduced. One option would be seaweed farming, the fastest growing aquaculture sector. Seaweed farming not only has the potential to be lucrative, but can also have ecological benefits, such as storing carbon and eliminating harmful nutrients from the water. The project will train the community on seaweed farming and help them acquire the relevant, sustainable gear. Another alternative livelihood option would be eco-tourism. The project will support both the training and purchasing of equipment for eco-tourism activities in the fishery closure zones mentioned above, with the aim of getting at least 200 households engaged in eco-tourism.

Such a holistic approach to fisheries management – i.e. improving implementation of fishery closure zones while also creating alternative employment opportunities for fishers – can help create a PECCA MCA that is sustainable and profitable for local communities in the long-term.
The project will not only help Tanzania achieve its targets under Sustainable Development Goal (SDG) 14, “Life Under Water”, in which it committed to protecting marine and coastal ecosystems, but also help it achieve SDG Goal 2 on Zero Hunger and Goal 8 on Employment.
The initiative is co-funded by the Global Environment Facility through the Western Indian Ocean Large Marine Ecosystems Strategic Action Programme Policy Harmonization and Institutional Reforms (SAPPHIRE) Project, executed by the Nairobi Convention. The project promotes policy and institutional reform to help improve the management of the Western Indian Ocean. The demonstration project is further supported by the Partnership Project for Marine and Coastal Governance and Fisheries Management for Sustainable Blue Growth in the Western Indian Ocean, led jointly by the Food and Agriculture Organization and the Nairobi Convention.
The Convention, part of the United Nations Environment Programme’s Regional Seas programme, serves as a platform for governments, civil society and the private sector to work together for the sustainable management and use of the Western Indian Ocean’s marine and coastal environment.
