Anne Gichangi is an agricultural economist working with KARI. Her research interest is marketing of agricultural produce. She is writing her final MSc thesis on the structure, conduct and performance of sweet potato marketing in Kenya. Gichangi, 44, says she enjoys the quick wins of working with horticultural crops: with a little input, farmers can harvest three crops per year. However, they have challenges marketing their increased produce. “Smallscale farmers face massive exploitation from the traders because they lack bargaining power caused by low economies of scale,” says Gichangi.
