Gem mining. A rush in 1994-1995 produced large amounts of yellowish green or brown Mali garnet. However the market was saturated, leaving the mines abandoned. Many diggings within a 15 km radius of the town of Diako.
Diako is the preferred spelling since it is found on the 1:250,000 topographic map sheet. Diakon is spelling government documents for the commune and arrondissement.

The cercles of Mali are divided into arrondissements. These are further divided into 703 communes, 19 urban communes and 684 rural communes. Unlike Communes or Cercles, Arrondissements have no administrative power or elected officials: they are merely territorial divisions or used to divide administrative duties. Often the borders of Communes and Arrondisements coincide, rendering the Arrondissement demarcation of the territory superfluous.

The boundaries of the arrondissement and commune are identical.
