Summary for Project title: R8273: Improving the livelihoods of small-scale sweet potato farmers in Central Uganda through a crop post harvest-based innovation system.

A programme designed to help farmers make the most of surplus production has identified 20 local and 300 potential global markets for fresh sweet potato grown in Kenya, Rwanda, Tanzania and Uganda. More than 2000 farmers were able to access new markets and cut their on-farm postharvest losses by 20-30%. Previously, these farmers were unable to appreciate the benefits of new, high-yielding varieties that produce three times as much as the former ones. The programme promoted a range of orange-fleshed sweet potato-based products. At the industrial scale, at least three private firms now absorb over 80 MT of dried sweet potato chips per month.
