This research note discusses the benefits and risks for Melanesian households arising from attempts to increasingly commercialise Canarium indicum, an edible tree nut indigenous to Papua New Guinea, the Solomon Islands and Vanuatu. Qualitative data were generated during workshops and interviews with Canarium industry stakeholders about the impacts associated with a series of interventions designed to encourage further commercialisation of Canarium. The findings are organised according to three dimensions that elucidate the social implications of industry development for local communities: (i) income and growth; (ii) equity; and (iii) voice and choice. Broader distribution of benefits within and between countries, as well as among supply chain actors, requires a stronger policy response at regional (Melanesia) and national scales, equitable gender representation to avoid reinforcing existing inequalities, and delegation of decision‐making power to the appropriate level to facilitate effective community participation and their links with other stakeholders. Thus, it remains to be seen whether Canarium‐related benefits arising from its commercialisation can be sufficiently reliable compared with either other sources of income (e.g. existing employment opportunities for those located near urban areas) or utilising the resource for subsistence purposes.
