Bijagos Archipelago and its tidal world of islands
Published on 09/22/2026 at 15:03 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Bijagos Archipelago is a chain of Atlantic islands off Guinea-Bissau, where mangroves, mudflats, sandbanks and shallow channels form a landscape closely tied to the tide. Its islands rise from the ancient deltas of the Rio Geba and Rio Grande, while the Bijagó people maintain communities with distinctive social and cultural traditions.
Bijagos Archipelago: islands formed from river deltas
The archipelago contains 88 islands and islets along the coast of western Africa. Its land and water are interwoven: mangrove channels reach between islands, broad mudflats appear with the tide, and palm groves and coastal woodland occupy the higher ground.
The archipelago is an active deltaic island system on Africa’s Atlantic coast. Sediments from the Geba and Corubal rivers meet tidal channels, estuaries and shallow marine areas. The result is a changing arrangement of sandbanks, mudflats and intertidal habitats rather than a simple line of beaches. the 88-island archipelago forms part of the Bolama-Bijagós Biosphere Reserve.
Mangroves, mudflats and Atlantic wildlife
Water dominates the ecological character of Bijagos Archipelago. Mangroves border channels and estuaries, while mudflats and sandbanks provide feeding areas for birds, fish and other marine life. Palm groves, littoral savannah and semi-dry forest add a terrestrial layer to the island environment.
Green turtles nest on the islands, and Poilão is a recognised turtle-nesting site. Leatherback turtles, manatees, dolphins, hippopotamuses, sharks and rays also occur within the wider coastal and marine system. Migratory shorebirds use the intertidal areas along the East Atlantic Flyway. The World Heritage property includes mangroves and tidal mudflats among its defining habitats.
UNESCO nominated the Bolama-Bijagós area as a Biosphere Reserve in 1996. In 2025, the Coastal and Marine Ecosystems of the Bijagós Archipelago – Omatí Minhô became a World Heritage property. Its protected areas include marine and intertidal environments across parts of the island system.
Bijagó culture across the island communities
The Bijagó people are the principal cultural community of the archipelago. Villages, farming areas, fishing grounds, sacred forests and coastal waters form parts of a social landscape shaped by customary practice. Rice cultivation, fishing, shell gathering, animal husbandry and forest use remain associated with island life.
Bijagó society is known for matrilineal elements and for ceremonies connected with age grades, initiation and spiritual traditions. Sacred islands and forest areas have a cultural status that differs from ordinary settlements and agricultural land. These traditions are inseparable from the geography of channels, forests, beaches and mangroves.
The island of Bolama carries the administrative name of the wider region, while Bubaque is a familiar base for journeys through the archipelago. Orango, João Vieira, Poilão and the Urok Islands form part of the protected landscape, each with its own combination of settlements, wetlands, forests and marine areas. traditional Bijagó resource management includes customary protection for sacred places.
