Natron extraction at Rig-Rig in the Kanem region is a traditional yet economically significant activity within the Lake Chad Basin. Natron, a natural blend of sodium carbonate and sodium bicarbonate, crystallizes in wadi depressions as groundwater evaporates during the dry season. This mineral has been manually harvested for centuries by local communities, who extract large slabs or blocks for trade. Rig-Rig serves as a primary collection and distribution hub for natron, which is highly valued across the Sahel as a mineral supplement for livestock and a raw material for soap making. The natron trade is a cornerstone of the regional economy, providing a vital source of income for nomadic and sedentary populations alike. Much of the product is exported to Nigeria, where demand for traditional industrial and agricultural inputs remains high. The labor-intensive extraction process takes place under extreme Saharan conditions, yet it remains one of the most reliable economic activities in northwestern Chad. Efforts are underway to improve the market value and supply chain for this unique natural resource.
