In southwestern Niger, single-use furnaces were identified during archaeological prospecting. An exhaustive inventory of 4,504 bloomery furnaces from Saga Gorou, near Niamey, allowed us to propose a spatial analysis of the catchment area of 32 km², representing the Sahelian landscape. The smelting sites of Bilfouda and Garbel have the highest concentrations of bloomery furnaces; each was mapped accurately from low-altitude aerial photographs. Six radiocarbon dates were obtained, ranging from the 4th to the 9th century. A spatial analysis with a series of mathematical tools (Ward’s method, k-means and minimum spanning tree) showed an organization of locations where groups had established bloomery furnaces. Four levels from local to global were identified: battery, cluster, site, and complex. Each was defined by a number of bloomery furnaces, an area, an operating time and control of production parameters. In a battery, bloomery furnaces can be arranged in a horseshoe shape or in a more-or-less-straight line. This organization of bloomery furnaces could be linked to the sociocultural context and reflects good workspace management.
