Abstract
The empirical results of 51 surveyed sago farmer households in three villages in sago using agrarian societies (SUAS), Keke/Tapala, Heatoare and Savaiviri in Malalaua District of Gulf Province, Papua New Guinea are reported in this study. Interactive intimacy with this staple food crop amongst the three villages, socio-culturally referred to as the “Moveave-Toaripis”, has not waned, and still continues to play a pivotal role in defining the adaptive and beneficial role of the interplay between humankind, a plant genetic resource and culture. From the traditional (micro-scale) sago starch processing point of view, it was established that about 11.33 bags of sago starch are processed per bole of sago stand for either selfconsumption within a sago farmer household level or for sale at local markets, for example, in Malalaua government station, or even as far as in Port Moresby city. The sale and self-consumption ratio was worked out to be around 7.25:2.75, which alludes to the probability that from all sago starch processing in these sago using agrarian societies (SUAS), 72.5% of the total output of sago starch is sold at the market, while sago farmer households within Malalaua area consume the remaining 27.5%. Therefore, the annual rural incomes derived from sale of sago starch at local markets for SUAS are based on these sago starch productivity indexes.
