Nutrition sensitive poverty and its correlates in Papua New Guinea: incorporating healthy diet targets into poverty measurement

Abstract As the international development community increasingly prioritizes nutrition outcomes, incorporating healthy diets into poverty measurements has important implications for what it means to be poor. Particularly for low- and middle-income countries dependent on domestic agriculture and low-cost food imports, evaluating the access to healthy diets is crucial to meeting food security goals. This paper provides the most expansive poverty assessment using the cost of basic needs approach in Papua New Guinea (PNG) in 15 years. In doing so, we compare a standard cost of basic needs poverty line where the food poverty line is defined by modest diets aligned with consumption patterns that meet a dietary energy (calorie) threshold; and a healthy diet food poverty line that meets both the dietary energy threshold and recommended nutrition targets. Results suggest that 43% of sample individuals live below the standard cost of basic needs poverty line. An additional 21% of sample individuals (64%) live below the healthy diet poverty line due to the relatively high cost of nutrient-dense foods in PNG. Multivariate regression analysis underscores the importance of household income diversification, whether via non-farm enterprise ownership or migrant remittances. Results reflect the unique challenges characterized by PNG’s remote landscape and lack of rural services, amplifying the need to improve rural-urban linkages that promote market access, educational attainment, and higher value employment opportunities.
