Gari as it is called in Anglophone regions of Cameroon or Tapioca in Francophone regions, is one of the most cassava derived products of the country. It is produced in all regions of the country, with North-West, South-West and Littoral Regions having the highest production. It is consumed largely by people from low socio-economic status (50%) , likely related to its low price and ease of preparation. This finding, coupled to the increasing market importance of gari, reinforces the need and challenge of improve its market quality, along with other cassava processing products, for poverty alleviation, and justify public initiatives in this respect. The high female representation in the gari value chain constitutes another support to bring an adaptive response to the challenge of gari development. The review of processing practices, consumer trends and quality attributes of gari raises out a formulation of the development challenge through the definition of objective relationships between cassavavarieties, gari processing practices and consumer's quality demand.
