Salinas do Porto Inglês is a coastal salt evaporation complex located on the southwestern shore of Maio Island in the Cape Verde archipelago. The site comprises traditional salt pans, associated storage facilities, and a landscape shaped by marine and aeolian processes. The salinas have been intertwined with regional maritime routes, agricultural systems, and local communities.

Geography

The salinas lie near the town of Porto Inglês on the island of Maio within the island nation of Cape Verde. The physical setting is characterized by a low-lying coastal plain bounded by the Atlantic Ocean and proximal to features such as Ponta Preta (Maio), Praia Gonçalo, and the bay of Baía do Porto Inglês. The climate is influenced by the Canary Current and the northeast trade winds known as the Harmattan in broader West African contexts, producing arid conditions similar to those on Sal Island, Boa Vista, and Santiago (island). Geologically, Maio is composed of volcanic substrata related to the Cape Verde hotspot and is situated on the African Plate off the coast of Senegal and Mauritania. The coastline near the salinas features tidal flats, lagoons, and sedimentary deposits comparable to features on Ilhéu Raso and Ilhéu Grande in the Barlavento Islands.

History

Records of salt exploitation in the Cape Verde islands date to early European Atlantic navigation involving Portuguese explorers such as Diogo Cão and Pedro Álvares Cabral, with colonial administration under the Portuguese Empire affecting resource allocation. Porto Inglês emerged as a harbor frequented by ships from Lisbon, Cadiz, Bordeaux, and Liverpool during the age of sail, linking the salinas to transatlantic routes that connected to São Tomé and Príncipe, Cape Coast Castle, and the Caribbean islands like São Vicente (Cape Verde) and Sal (island). In the 19th century, traders from Great Britain, France, and The Netherlands engaged in salt commerce alongside local Cape Verdean families descended from settlers and sailors associated with Madeira and Azores. During the 20th century, administrative changes under the Estado Novo (Portugal) and later independence movements culminating in the Carnation Revolution influenced economic priorities; after independence, the government of the Democratic Republic of Cape Verde and municipal authorities of Maio (municipality) oversaw resource stewardship. The salinas also experienced impacts from 20th-century maritime events involving ports such as Mindelo and shipping lines like Companhia das Ilhas.

Salt Production

Traditional production at the salinas follows methods similar to Mediterranean and Atlantic saltworks such as those on Santo Antão, Sicily, and Maras (salt mines). Seawater is channeled into a series of concentrative ponds and crystallizers adjacent to tidal channels influenced by the Atlantic Ocean and local tidal regimes. Technicians and laborers historically used tools comparable to those in the Salinas de Fuencaliente and Salinas de Janubio on Lanzarote, working during dry seasons when evaporation driven by Trade winds and solar radiation is maximal. Salt grading and storage connected the site to markets in Praia (city), Mindelo (São Vicente), Lisbon, Funchal, and coastal West African entrepôts. Commercial shifts introduced mechanized pumping and modern packaging used in other saltworks such as Salar de Uyuni adaptations, while artisanal production persisted for local culinary uses tied to Cape Verdean dishes and fisheries operating from the harbor of Porto Inglês.

Ecology and Biodiversity

The salinas create specialized habitats that support saline-adapted flora and fauna akin to ecosystems in Etang de Thau, Doñana National Park, and the Ría Formosa. Halophytic plants related to genera found on Boa Vista and Santiago (island) colonize margins, while benthic microalgae and evaporite mineral assemblages provide primary productivity. The area is important for migratory and resident avifauna, attracting species associated with the East Atlantic Flyway such as waders and terns comparable to observers’ records from Ilhas Desertas and Raso Islet; notable bird groups include analogues of populations recorded in surveys at Praia da Gamboa and Lagoon of Maio. Marine connectivity links the salinas to offshore fisheries targeting species exploited around Baleeira and influences marine mammals occasionally recorded near Boavista and Sal (island). Conservation concerns mirror pressures seen in other Macaronesian contexts like Madeira (island) and the Azores—including habitat alteration, invasive species introductions, and climatic shifts tied to variability in the Atlantic Multidecadal Oscillation and regional sea surface temperature anomalies.

Cultural and Economic Importance

Locally, the salinas are embedded in Maio’s cultural landscape alongside festivals, crafts, and culinary traditions observed in Porto Inglês and communities across Maio (municipality). Salt from the pans has served domestic markets, small-scale export, and artisanal industries comparable to salt-based economies in Sal (island), São Vicente (Cape Verde), and parts of Senegal and Mauritania. Heritage and tourism initiatives connect the site to regional promotion carried out by agencies similar to the Cape Verde Tourism Board and municipal cultural programs in Maio, drawing visitors interested in industrial archaeology like that at Fábrica da Baleia and salt heritage such as Saline de Pedra de Lume. Economic strategies debate sustainable exploitation versus conservation in frameworks referenced by international bodies including comparisons to UNESCO-listed salt landscapes and Natura 2000-like schemes in Macaronesia.
