The Pemba marine protected areas, newly established off Tanzania’s Zanzibar archipelago, are being held up by conservation researchers as a working example of community co-management. The reserves show that protection does not have to mean excluding the fishing communities who depend on the water.
The reserves cover reef and seagrass habitat that supports both biodiversity and the small-scale fisheries much of Pemba’s coastal population relies on for food and income. Rather than imposing a top-down no-take zone, the arrangement sets out zoned areas with defined community rights and responsibilities. Rotating closures let fish stocks recover while still permitting access elsewhere.
Years of talks behind a simple-looking map
Researchers involved in the process describe the negotiation period as lengthy and, at times, difficult. Early resistance came from fishers who worried that any protected area would simply mean lost livelihoods. Community buy-in grew, organisers say, as pilot closures in smaller areas showed visible increases in fish catches in adjacent waters once stocks recovered. That pattern is consistent with research on temporary fishery closures elsewhere in the Indian Ocean.
The approach contrasts with earlier marine conservation efforts in the region. Those were imposed with limited local consultation and saw patchy compliance as a result. Pemba’s model instead gives communities a formal role in monitoring and enforcing the zones. Conservation researchers say that arrangement tends to produce more durable compliance than external enforcement alone.
A case study with wider relevance
The timing carries added significance. Delegates at the COP17 biodiversity summit in Yerevan have spent the past two weeks debating how to meet the global target of protecting 30% of the world’s land and seas by 2030. The goal is to do so without repeating the mistakes of earlier efforts that sidelined Indigenous and local communities. The Pemba marine protected areas are increasingly cited in that debate as evidence that community-led designs can scale.
Researchers caution that replicating the model elsewhere will require similarly patient, resource-intensive negotiation. That is not always available where conservation funding is tied to short grant cycles. The International Union for Conservation of Nature has estimated that existing funding covers only a fraction of what protected areas in East and Southern Africa need to operate effectively. That gap constrains how many Pemba-style co-management processes can be supported at once.
For now, Pemba’s fishers and conservation partners describe the reserves as a long-term bet that has already started to pay off in better catches. The model offers a template that could inform how the Yerevan Pathway’s implementation guidance treats community rights going forward.
Local government officials on Pemba say they are already fielding enquiries from district authorities elsewhere in Tanzania interested in adapting the co-management framework to their own stretches of coastline. Conservation partners caution that each site will need its own negotiation process tailored to local fishing patterns and governance structures, rather than a template applied wholesale.
Marine biologists monitoring the reserves say early data on coral cover and fish biomass inside the closed zones already compares favourably with longer-established marine protected areas elsewhere in the western Indian Ocean. They stress, however, that several more years of monitoring will be needed before firm conclusions can be drawn about the reserves’ long-term ecological trajectory. Pemba’s district fisheries office says it plans to publish annual catch and biomass data going forward, aiming to build a public record that could help settle debates over how quickly community-managed closures translate into measurable ecological gains for similar reserves elsewhere in the region.
