Labor Banking

The mar muos system allows labor invested into millet cultivation to be withdrawn in the form of group labor.

Millet is a particularly advantageous crop to grow; interplanting it with sorghum increases returns per unit of both labor and land, without a proportionate rise in labor demands during bottlenecks. [IMAGERY] [REFS]
Millet's value is enhanced by its flexibility. It can be eaten, and is available long before other staples are harvested. It can be marketed, and is the Kofyar's second major cash crop after yams. It can also brewed into beer for sale, mar muos, or social occasions. [ IMAGERY]
"Banking" labor as millet allows the farmer to mitigate fluctuations in the availability of household labor. The Kofyars' intensive cultivation strategies are planned tightly enough that the loss of one adult to illness during a key part of the season may endanger an entire crop. [IMAGERY ]
