Papua New Guinea is rich in natural resources. Yet, nearly a third of the population have income less than the minimal deemed necessary to afford basic needs including food. While figures for food poverty are unavailable and could be lower, policies can be introduced to improve affordability of food. This paper draws on the macroeconomic constraints that have contributed to food poverty and offers lessons on how best to address these. The domestic markets for food can be better integrated to improve food security, reduce price volatility and increase income for the suppliers.
