Abstract
This paper investigates the extent of technical and organisational transformations in the milling segment of the rice value chains in Ghana and Ivory Coast, which is discussed against the literature on agricultural value chain transformations. The method is based on rice miller's quantitative data and stakeholders' interviews. The results reveal that both countries are undergoing technical change and a shift of value chain governance towards vertical integration, implemented at larger scale in Ghana. The differences observed are attributed to variations in production systems, demand for local rice, currency conditions, and policy approaches in the respective countries.
