In 2012 there was almost nothing here - just empty desert beside a newly paved highway. Then the government of Mauritania decided a town should exist, and so one did. Chami was planned before its first families arrived: streets surveyed, lots numbered, a green belt of nearly fifty thousand trees set in the sand to break the wind. It was an experiment in control, an attempt to gather scattered nomads into one place the state could actually reach. What no planner fully anticipated was the gold.
Chami rose to solve a problem the government called 'anarchic sedentarization' - the way nomads, settling on their own terms, kept forming villages no authority had sanctioned. The answer was a designed town near the N2 highway, the paved road running from Nouakchott in the south to Nouadhibou in the north, about 25 kilometers inland from the Atlantic. Before anyone moved in, the infrastructure went up: plans for 5,680 residential lots, 805 commercial units, administrative buildings, all laid out across 600 hectares. Around the edges, a belt of roughly 50,000 plants - mostly the hardy Prosopis juliflora - was planted to hold back the relentless wind. The state would concentrate the population where it could finally deliver services.
The plan did not unfold as written. The nomads it was built for mostly stayed away; land in Chami cost more than their herding incomes could cover. Instead, gold rewrote the town's purpose. Strikes in the surrounding desert turned Chami into Mauritania's self-styled 'capital of gold,' pulling in prospectors and migrants from Mali, Sudan, and beyond. By the 2023 census the population had reached around 4,214 - and tellingly, more than two-thirds of them were men, the lopsided signature of a frontier mining town. A place built to settle wanderers had become a magnet for a different kind of restless arrival.
The gold carries a cost the maps do not show. Artisanal mining around Chami relies on mercury, used without regulation to pull gold from crushed ore, and the practice has left severe contamination in its wake. The danger does not stay put. The prevailing northeast wind - the harmattan - is believed to carry mercury vapor west, straight toward the Banc d'Arguin National Park, a UNESCO World Heritage Site and one of the most important refuges for migratory birds on Earth. A town invented to impose order on the desert now sends an invisible plume toward one of the planet's great wild coastlines. There is even a quieter controversy about why Chami sits exactly where it does: a rival of the president of the day ran a better-placed waystation to the south, and many believe the town was sited elsewhere on purpose.
Chami lies at 20.16 degrees N, 15.98 degrees W, on the N2 highway about 25 kilometers inland from the Atlantic. From the air, look for a strikingly regular grid of streets and a surrounding ring of planted greenery - an unmistakably engineered town set against open Saharan desert, with the coastline and Banc d'Arguin shoals to the west. Nouadhibou (GQPP) lies to the north; Nouakchott (GQNN) to the south. Watch for blowing dust on northeast harmattan winds.
