5.5.9 Suitability of storage systems for fresh cassava roots on a small farmholder level

There are differences among farmers cultivating cassava, e.g. regarding the economical status of the crop, the resources for production input (work, capital and soil) and the market orientation and proximity. This makes the requirements of small farmholders regarding the storage of fresh cassava roots, very varied and not at all homogeneous.

The majority of West African small farmholders produce for the purpose of self-sufficiency with minimum resources. Cassava which is an undemanding plant in every respect, primarily serves the purpose of self-sufficiency and risk reduction. The proportion of production sold is generally very low.

The processes described above allow a very limited prolongation of storage. They mostly require an additional input of work and/or of capital which, in relation to the status of the cassava production, is relatively high. Some methods, i.e. cooling by means of external energy, constitute a technological leap and necessitate a functioning infrastructure.

For the majority of small farmholders, the methods described provide no solution to their specific storage problems (long-term, secure, low losses and low-cost).

For farmers who have attained a certain integration into the market (fresh selling), individual methods are definitely of some interest. These can serve to bridge time gaps by minimally prolonging storage ability and by solving logistic problems by providing transport containers. The use of the methods described however, will only be successful if production and sales up to the final consumer can be integrated into a system.

For the majority of farmers who produce cassava at some distance from the markets, other strategies become essential if their storage problems are to be solved. These strategies go in the direction of processing in order to produce products which can be stored. Some processes, e.g. the production of cassava chips as described below, can skill be included in the fields of storage and post-harvest technology. Other processes, e.g. the production of gari, are clearly a matter for foodstuff technology and are no longer a subject for this investigation.
