On the peaceful shores of the lagoon bordering Grand-Popo, time seems to stand still. Here, between the Mono River and the ocean, an age-old story continues to unfold: the artisanal extraction of salt. Xwla women pass down this skill with quiet dignity, turning lagoon water into crystals of remarkable purity.
The Grand-Popo salt marshes are more than a production site. They bear living witness to a traditional economy that resists industrialisation, to an intimate bond between communities and their environment, and to one of the last human activities perfectly integrated with the lagoon's fragile ecosystem.

White gold of Grand-Popo
Grand-Popo salt is called white gold by local communities. The name is no exaggeration: for centuries, salt was a valuable trading currency along the West African coast, and it remains a pillar of the local economy today.
What makes Grand-Popo salt so special is its origin. It is not mined or industrially evaporated. It is born from the meeting of brackish lagoon water and tropical sun in shallow basins dug into the clay. The cycle is slow: several days, sometimes a full week, pass between the moment water enters the basins and the moment the first crystals appear.
The result is a coarse, moist salt with a more pronounced mineral flavour than industrial table salt. Its richness in trace elements (iodine, magnesium, potassium) comes from the lagoon water itself, a blend of fresh water from the Mono and salt water from the Atlantic.
The quality of this salt is recognised throughout Benin. Grand-Popo cooks will tell you that artisanal salt transforms a dish. Even the famous grilled fish at Chez Paterne owes its unique flavour to this lagoon salt.
For visitors, the salt marshes offer a striking spectacle. At certain hours, when the sun is at its zenith, the basins sparkle with a thousand lights, creating an almost surreal landscape. The air is heavy with the smell of iodine and salt, the silence broken only by the rustle of wind in the palms and the scraping of tools on the salty ground.
Ancestral harvesting technique
The salt harvesting process in Grand-Popo is an art passed from mother to daughter for generations. It begins with a system of canals and wooden sluices that channel lagoon water into evaporation basins, called salt marshes.
These basins are vast, flat expanses divided into compartments by ridges of clay soil. Water circulates slowly, moving from one basin to the next, evaporating progressively under the tropical sun. After four to seven days, depending on heat and humidity, the water reaches sufficient salt concentration. This is when crystals begin to form on the surface.
The women step in at this critical stage. Bent over the basins, armed with long wooden scrapers, they gently skim the surface to collect the crystals without touching the clay bottom, which would taint the salt. Every gesture is precise, economical, the fruit of decades of practice.
The moist salt is then washed in clear water basins to remove the last impurities, then spread on straw mats or tarpaulins for drying. Two to three hours of sun is enough to obtain white, dry salt, ready for packing.
All tools are entirely natural: wooden scrapers, straw mats, clay basins, calabashes for transport. Nothing is imported, nothing pollutes. This complete autonomy is a source of pride for the Xwla women, who control every step of production, from water to sale.
The salt women
The salt marshes of Grand-Popo are the women's kingdom. They harvest the salt, wash it, dry it and sell it. The men fish in the lagoon and the ocean; the women process and market. This division of roles is ancient and respected.
Xwla women start work at dawn, before the heat becomes crushing. By 5 am, they are already in the salt marshes, scraping, washing, spreading. By 9 am, the harvest day is well underway. The afternoon is devoted to packing and selling.
The work is exhausting, but the women speak of it with pride. Being a salt woman is a respected status in the community. It testifies to the ability to support one's family through one's own work and to carry on the traditions of one's ancestors. Girls learn the trade by accompanying their mothers from a young age, first playing at the edges of the basins, then gradually taking on tasks.
The work is organised collectively. Several women from the same family or neighbourhood work together, sharing the basins and helping each other with heavier tasks. This community dimension is essential: salt is a collective good before it is a commercial product.
Today, faced with competition from cheap industrial salt, the salt women are organising to add value to their production. Cooperatives are forming, quality labels are emerging. Grand-Popo artisanal salt is finding a new clientele among tourists and restaurants that value local products.
Visiting the salt marshes
A visit to the salt marshes is an immersive experience that reveals ancestral knowledge and the women who carry it forward. It is best done early in the morning, when work is in full swing.
The salt marshes are located a few hundred metres from central Grand-Popo, on the other side of the lagoon. Access is on foot from the main jetty, or by pirogue for a more picturesque approach. A path crosses the palm grove before opening onto the vast, flat expanse of the salt marshes.
The visit lasts about an hour and a half. A local guide, often a Xwla woman herself, explains each step of the production. You can watch the scraping of crystals, the washing, the drying. The women willingly answer questions about their work and life around the salt marshes.
It is customary to bring a small gift for the women who receive you: a packet of sugar, soap or matches. This simple gesture is always appreciated and shows respect for their work.
Do not leave without tasting a salt crystal directly from the drying mats. Its strong, mineral flavour will leave an unforgettable impression. Photographers will appreciate the morning light that makes the basins sparkle. Bring shoes that can get wet and a hat for the sun.
Buying artisanal salt
Buying artisanal salt directly from the producers is the best way to support the local economy in a direct and ethical way. Grand-Popo salt is sold in packs of 250 grams to 2 kilograms, prepared by the women themselves.
Prices are very reasonable: between 500 and 1,000 FCFA per kilo (0.76 to 1.50 EUR). A 500-gram pack, ideal as a souvenir, costs between 250 and 500 FCFA (0.38 to 0.76 EUR). Compare with industrial salt sold in supermarkets, and you will understand why artisanal salt is an investment in quality and the preservation of tradition.
You can buy the salt directly at the salt marshes, at the Grand-Popo market (where the women have a dedicated stall) or at some craft shops near the jetty. Restaurants and ecolodges sometimes sell it to their guests.
Grand-Popo artisanal salt keeps well if stored in a sealed container in a dry place. It does not clump like fine salt. Use it to season grilled meats, fish or vegetables, or give it as a gift to food-loving friends. Some women also offer it flavoured with chilli or ginger, a delicious local speciality.
Grand-Popo salt is also used traditionally for its medicinal properties: as a mouth rinse, as a poultice for muscle pain or as an inhalation to clear the respiratory tract. These uses, passed down through oral tradition, show the central place of this product in daily life.
Economic role
Artisanal salt is a pillar of the local economy in Grand-Popo. It directly supports several hundred families, mainly single women or widows for whom this activity represents their only source of income.
The salt sector is entirely local. The basins are dug on community land, the tools are made on site, distribution happens through neighbourhood markets. Every franc spent on a pack of salt stays within the community. This short supply chain is a model of economic resilience.
However, the sector faces challenges. Imported industrial salt, cheaper, is gaining market share. Younger generations are less attracted to a physically demanding and poorly recognised trade. Climate change is altering the tidal regime and the lagoon's salinity.
Several initiatives aim to strengthen the sector. Women's cooperatives obtain microcredit to improve their tools. Management and marketing training helps them better value their production. Ecotourism brings a new clientele sensitive to local products and traditions.
Visitors to Grand-Popo play an important role in this dynamic. By buying artisanal salt, visiting the salt marshes, and spreading the word about this tradition, they help preserve an age-old skill and support the economic independence of Xwla women.
Preservation and transmission
Passing on salt-making knowledge is a crucial challenge for Xwla communities. Girls learn the trade by watching their mothers, but this oral and practical transmission is fragile.
Several associations work to document this heritage. Workshops bring together older women and young girls to exchange techniques, tools and beliefs associated with salt. These gatherings are also an opportunity to discuss possible innovations to improve production without altering it.
Preservation of the lagoon ecosystem is inseparable from preserving the salt marshes. Salt quality depends directly on the health of the lagoon: pollution, silting and changes in salinity threaten production. The salt women are the first to monitor the lagoon's condition and participate in site protection efforts, particularly mangrove replanting and channel cleaning.
The Zangbeto, traditional community guardians, also watch over the salt marshes. Their spiritual authority deters theft and conflicts over use, and their presence reinforces the link between tradition and conservation.
Buying artisanal salt means supporting this chain of transmission and helping ensure an age-old skill does not disappear.
