ABSTRACT
The paper examines the main characteristics of cassava production and gari marketing in North-West Province, Cameroon. Data collection procedures are outlined, together with an assessment of the problems encountered in the field in commodity flow and price surveys.
Analysis of price trends reveals the seasonal character of gari marketing and the sometimes complex way in which supply and demand functions at particular periodic markets influence urban price setting and intra-regional trade. The volume, value and spatial pattern of gari flows is assessed, indicating a predominantly two-level rural to urban distribution system which functions without recourse to a multiplicity of middlemen except under exceptional albeit rational circumstances. It is concluded that detailed study of the movement of a single commodity and the role of traders in its distribution can go some way towards revealing the nature of the functional relationship between market-places, and the structure and mechanisms of periodic marketing.
