Rwanda turns to sweet potatoes as wheat flour baking substitute

Rwanda is seeking to increase sweet potato production from eight to 30 tonnes per hectare using six new varieties so as to replace wheat in baking and thus cut imports, Jean Ndirigwe, a sweet potato breeder at Rwanda Agriculture and Animal Resources Board (RAB), said. ALSO READ: Should Rwanda be spending billions on wheat imports? Rwanda has started to look for alternative sources of wheat imports following hefty trade sanctions on its major supplier, Russia. Prior to the sanctions, Rwanda heavily depended on Russia for wheat imports, with at least 64 per cent of the country’s wheat coming from Russia. However, Russia is now facing export and import sanctions as a consequence of its military incursion into Ukraine, which has disrupted this supply. The data indicate that in 2019, Russia was Rwanda’s top wheat import partner where more than 73,324 tonnes worth $17.5 million (approx. Rwf21 billion) were imported, while in 2020, the United Kingdom came first with 67,145 tonnes of wheat for $16.1 million (approx. Rwf19 billion), followed by Russia with over 60,855 tonnes for $15.2 million (approx. Rwf18 billion). “We have sweet potato varieties that can increase production. Sweet potatoes can replace wheat in baking factories and cut the wheat imports,” he said.

With only 15 per cent of sweet potato farmers able to invest their own money in buying new varieties of sweet potato seeds, agricultural researchers are set to establish demonstration plots that will stimulate farmers’ demand. Six new sweet potato varieties that were recently introduced are expected to increase yields.

The number should increase and also be given arable wetlands for multiplication,” he said. Jan Low, a principal scientist with the International Potato Center (CIP), said that if Rwanda invests in increasing sweet potato yields, it could replace wheat at between 30 per cent and 60 per cent in baking factories. “Such investment can reduce government spending on wheat imports,” she said. Data from the Ministry of Trade and Industry show that in 2020, Rwanda spent over $44 million (approx. Rwf53 billion) on importing more than 177,740 tonnes of wheat, representing an increase of over 10 per cent compared to more than $40.8 million (approx. Rwf48 billion) spent the previous year. Telesphore Ndabamenye, the Director General of Rwanda Agriculture and Animal Resources Development Board (RAB), said that high-yielding sweet potato varieties to replace wheat in baking are also rich in Vitamin A. “There are over six varieties we want to scale up since they provide high productivity and are also resistant to diseases. We have to increase seed multipliers. Sweet potatoes are good raw materials needed in baking and they could help cut wheat imports. About 80 per cent of what is needed in baking can come from sweet potatoes,” he said.

Sweet potatoes, especially the orange variety, are rich in energy, vitamins, calcium, and iron among other nutrients which are needed for improving nutrition. However, Jeanne d’Arc Uwemeyimana, a sweet potato farmer and seed multiplier, said that sweet potato vines are still expensive. “I am selling one kilogramme of sweet potato vines at Rwf500. This is derailing efforts to increase production,” she said. With the orange-fleshed sweet potato vines, she has increased output from 10 tonnes to between 20 and 30 tonnes per hectare.
