ABSTRACT
Traditional methods of storage or storage avoidance techniques for root crops are important in the various subsistence economics in Papua New Guinea, as most people are directly dependent on root crops at the subsistence level. These methods are reviewed for the major root crops (sweet potato, aroids and yams). These include both pre-harvest and post-harvest techniques.
Additional storage methods which are not widely used but which have been evaluated and may be useful at the village level are also discussed. Processing of root crops has not become widespread in Papua New Guinea, although a significant advance has been made with sweet potato. This process is described, together with other possibilities.
