A critical shortage of a superior cassava variety, Mumba, in central zone regions of Tanzania is jeopardizing the country's efforts to meet its cassava supply agreement with China, which demands 2 million tonnes annually. This situation arises as the current planting cycle of the favored variety has expired, and seed purification by the responsible breeder is still in progress. The lack of this variety is demoralizing farmers in Dodoma and Singida regions, who have been encouraged by the government to increase cassava production to meet China's demands. The government is working to enhance cassava productivity and access to necessary technologies while local companies are registered for cassava exportation to China. However, the world price of dry cassava does not cover the production costs in Tanzania, highlighting the challenge of balancing supply and demand in the market.
