Bijagos Archipelago: islands shaped by the Atlantic tide
Published on 09/23/2026 at 09:00 | Editorial responsibility: Rafael MĂĽller, Editor-in-Chief AD HOC NEWS
Bijagos Archipelago is a broad Atlantic island system off Guinea-Bissau, where mangroves, mudflats and shallow channels form a landscape shaped by the tide. Its 88 islands rise from the ancient deltas of the Geba and Grande de Buba rivers, while BijagĂł communities maintain settled island traditions.
The contrast between land and water defines the archipelago. At low tide, sandbanks and mudflats extend beside mangrove channels; at high tide, many passages become waterways. The result is an environment that belongs to the coast, the estuary and the open Atlantic at once.
Bijagos Archipelago and its deltaic island landscape
The archipelago lies off the coast of Guinea-Bissau in western Africa. Its islands and islets occupy the meeting place of river sediments and Atlantic waters, with broad intertidal areas between wooded shores.
88 islands of Bijagos belong to the Bolama-BijagĂłs Biosphere Reserve, nominated in 1996. The reserve covers more than one million hectares of marine and terrestrial space, including mangroves, mudflats, palm groves, littoral woodland savannahs and semi-dry forests.
Many islands remain low above the surrounding water. Beaches, tidal creeks, forest edges and open sandy areas form a sequence of coastal habitats rather than a single continuous shore. The channels are an essential part of the landscape, linking islands that can appear separate from the mainland.
Mangroves, turtles and Atlantic wildlife
Water dominates the archipelago’s wildlife. Green turtles use its beaches for nesting, while leatherback turtles also occur in the protected coastal and marine environments. Poilão Island is an important nesting site for marine turtles.
The World Heritage property includes mangroves, mudflats and intertidal zones with endangered turtles, manatees and dolphins. More than 870,000 migratory shorebirds use the wider coastal system, joining resident birds around the shallow waters and exposed feeding grounds.
Hippopotamuses also inhabit the archipelago’s marine environment, an unusual feature of this deltaic setting. Fish, rays, sharks, molluscs and crustaceans occupy the waters, while mangrove roots and mudflats provide shelter and feeding areas.
The marine habitats are connected to the islands’ seasonal rhythms. Tides expose and cover the flats, and the movement of water carries sediments through the channels. Visitors encounter a coastal environment whose visible character changes with the level of the Atlantic.
BijagĂł life, sacred places and island communities
The BijagĂł people form the main cultural community of the archipelago. Fishing, agriculture, livestock keeping, shell gathering and forest use remain part of island life, alongside ecological tourism.
Bijagó culture includes initiation ceremonies, spiritual practices and community rules connected with forests, beaches and islands. Some places have ceremonial significance and are not ordinary settlement areas. The relationship between customary practice and natural resources is part of the archipelago’s cultural landscape.
Orango, Bubaque and Canhabaque are among the islands associated with island communities and distinctive local traditions. Bubaque is a principal settlement and a recognised point of arrival for travel across the archipelago.
The protected areas include Orango Islands National Park, JoĂŁo Vieira and PoilĂŁo Marine National Park, and the Urok Community Marine Protected Area. These designations sit within the broader biosphere reserve and connect conservation with local resource use.
