Pemba Island is a Tanzanian island in the Zanzibar Archipelago, lying in the Indian Ocean off the east coast of Africa. Known in Arabic as al-jazira al-khadra, “the Green Island,” it sits north of Unguja, the main island of Zanzibar, and east of mainland Tanzania across the Pemba Channel. Its landscape, agriculture, and coastal waters have made it distinct from the more heavily visited island of Zanzibar.
- Part of the Zanzibar Archipelago and the United Republic of Tanzania
- Located north of Unguja and east of mainland Tanzania
- Nicknamed “the Green Island” for its dense vegetation and fertile land
- Known for clove production, fishing, and quieter coastal tourism
- Relevant to contemporary design and hospitality through remote, site-specific projects
Where is Pemba Island?
Pemba lies about 50 kilometres north of Unguja and is separated from the mainland by the Pemba Channel. It belongs to the Zanzibar archipelago, but it has its own geography, economy, and cultural rhythm. The island is smaller than Unguja and less urbanised, with a landscape of rolling hills, mangroves, coral rag, and enclosed inlets that support fishing and small-scale farming.
Its location matters because it sits at a crossroads of Swahili coastal history. Trade, Islam, agriculture, and maritime movement shaped the island over centuries, linking it to the wider Indian Ocean world. That history still appears in the architecture, language, and everyday material life of the island.
Why is Pemba called the Green Island?
The nickname comes from the island’s unusually lush vegetation. Pemba receives more rainfall than much of the surrounding region, which supports thick plant growth and fertile soils. Clove trees, mangoes, bananas, cassava, and other crops thrive there, and cloves in particular have long defined the island’s economy and landscape.
This greenery is not just a romantic label. It reflects the island’s ecology and its agricultural use. Clove plantations, small farms, and patches of secondary forest shape how land is occupied and worked. For visitors and makers of place-based projects, that abundance changes the visual character of the island: shaded roads, dense coastal edges, and interiors that feel more enclosed than on drier islands nearby.
What does Pemba matter for in design and culture?
Pemba matters because it offers a different version of Zanzibar: less polished, less promoted, and more tied to local livelihoods. That makes it important for writers, designers, and architects interested in place as a system of materials and labour rather than a postcard image. The island’s built environment is shaped by coral stone, lime, timber, palm products, and vernacular techniques adapted to heat, humidity, and coastal weather.
It also matters as a setting for contemporary hospitality projects that depend on landscape as much as on architecture. A remote island changes the logistics of building: materials must be brought in, local labour and maintenance become central, and the final design has to respond to wind, salt, water, and access. On Pemba, a project succeeds when it works with the island’s ecology instead of ignoring it.
How is Pemba different from Zanzibar?
Unguja, often simply called Zanzibar, attracts most of the international attention, while Pemba remains quieter and more rural. Unguja has the better-known Stone Town and a larger tourist economy; Pemba is more associated with agriculture, fishing, and lower-density development. The difference is visible in the built fabric, transport links, and pace of life.
That contrast shapes how the island is perceived. Pemba is not a separate country or an isolated outpost; it is part of the same archipelago and national history. But its relative remoteness has protected much of its landscape from the kind of heavy transformation seen in more touristed places, which is exactly what gives it value in discussions of conservation, hospitality, and coastal design.
Frequently Asked Questions
Is Pemba Island part of Zanzibar or Tanzania?
Pemba is part of the Zanzibar archipelago, which itself is part of Tanzania. Zanzibar and mainland Tanganyika united in 1964 to form the modern state of Tanzania. Pemba therefore belongs to both a specific island group and the larger national territory.
What is Pemba Island known for?
Pemba is best known for its fertile land, clove plantations, fishing culture, and green, hilly scenery. It is also known for being less developed and less heavily visited than Unguja. That combination gives it a strong identity within the archipelago.
Why do contemporary design projects pay attention to Pemba?
Design projects use Pemba because the island offers a strong sense of place and a demanding coastal environment. Building there requires attention to climate, material supply, local craft, and maintenance. Those conditions make Pemba relevant to architecture, hospitality, and landscape-led design.
