A man operates a diesel-powered corn mill in a roofed shed while another adjusts a grain bag nearby. He grinds grain into a plastic container resting in a headpan. Another headpan filled with maize (corn, bledju in Nafaanra) sits in front with a calabash used as a scoop sitting on top. Other plastic and metal containers sit nearby. Diesel-powered grinding mills first began to be set up in Ahenkro in the 1980s. They have become more common over the years, reducing the need for maize and other dried foodstuffs to be pounded by hand in wooden mortars. At the same time, they have expanded the need for cash income as grinding has become part and parcel of household budgets. Ahenkro, 2009.
