The harvesting time varies according to the production region during the dry season, ranging from July to November. Most cashews are sold in the shells to traders who frequent farmers’ villages. However, the price of cashews in the shell is considerably lower than that of fresh or processed cashew nuts, which are mainly processed by smallholder farmers. Cashews are a potential export commodity because of their high economic value in the global market and as an added value for income generation in the smallholder farming system. This study is a systematic review of the economic impact of the cashew nut home industry focused on Southeast Sulawesi, East Nusa Tenggara, and West Nusa Tenggara as the three largest provinces producing cashew kernels in Indonesia. The metadata suggest that processing cashew nuts is a key element in enhancing farmers’ welfare, particularly for those in eastern regions, which are aff...
