Sunflower commercialisation in Singida Region, Tanzania has been successful. The successes include increased oilseed production, expanding processing capacity and declining rural poverty. Policies and efforts by development agents to promote sunflower commercialisation have increased the number of actors and service providers. Accumulation from sunflower and other enterprises, including livestock, have not only improved livelihoods, but also contributed to household economic diversity. This paper examines the interactions between activities involved in sunflower production and other livelihood strategies. For example, the paper examines local dynamics in policy and business contexts that have shaped livelihood options available and people’s choices of which option they undertake, and the corresponding outcomes, and reasons for such commercialisation trajectories. The study aims to inform local, regional, and national strategies, to pursue more inclusive and sustainable agriculture development, and widen options and pathways for men and women in Mkalama and Iramba districts of Singida Region.
