The gendered effects of rainfall shocks on stunting: Evidence from Papua New Guinea

The gendered effects of rainfall shocks on stunting: Evidence from Papua New Guinea

Rainfall fluctuations significantly reduce welfare for poor rural households in low- and middle-income countries dependent on rainfed agriculture for consumption, and the effects of these shocks can be borne disproportionately by vulnerable household members, particularly children and girls. We present new evidence around the effects of rainfall fluctuations on child anthropometric status in Papua New Guinea, an understudied context characterized by some of the highest stunting rates in the world. We show that negative fluctuations in rainfall within the first 12 months of life lead to a reduction in height-for-age and weight-for-age (though not stunting), but this effect is observed only for girls.

Papua New Guinea food price bulletin: August 2026

Papua New Guinea food price bulletin: August 2026

This bulletin reports on food price trends from major markets in Papua New Guinea (PNG), for the second quarter (Q2) of 2026 using the data collected by Fresh Produce Development Authority (FPDA). During this period, two rounds of data were collected in all markets in May 2026. In April, two rounds of data were collected in Banz, Goroka, Kokopo, Lae and Mt. Hagen markets; however, only one round of data was collected in Port Moresby. In June no survey data collection was conducted in Kokopo and Mt. Hagen, whereas Banz, Goroka, Lae and Port Moresby each had one round. This report analyzes month-over-month changes in Q2 2026 (April to June) and available data through August for selected markets. The bulletin compares prices with the previous quarter (Q1 2026: January to March) and the same period in 2025 (Q2 2025). Prices are reported in real PGK per kilogram (i.e., adjusted for inflation using the FAO Consumer Food Price Index (PCI) and price gaps from July 2025 to August 2026 filled using a growth rate calculated from quarterly PCI data provided by the PNG National Statistical Office (June and September 2025). This bulletin focuses on selected staples (sweet potato, taro, cassava, cooking banana and rice), vegetables (English cabbage, capsicum, and carrot) and fruits (pawpaw and pineapple). For longer time series data and interactive tools, visit the IFPRI website to create graphs, compare prices and commodities, and download food price data here.

When the rains fail, who goes hungry? Rainfall, gender, and child nutrition in Papua New Guinea

Key takeaways – Low rainfall hurts young girls’ nutrition. A study in PNG found that below-average rainfall in a child’s first year of life reduced height-for-age and weight-for-age scores for girls under 5, while boys showed no comparable effects. – Even routine rainfall shortfalls matter. The analysis focused on normal year-to-year rainfall variation, not major disasters, yet still found measurable impacts on child nutrition in rural PNG. – Drought responses should consider gender. As PNG prepares for a potential El Niño-driven drought, policymakers may need targeted measures to protect girls and address unequal household burdens during food shortages.

2023 Social Accounting Matrix for Papua New Guinea

2023 Social Accounting Matrix for Papua New Guinea

The 2023 Papua New Guinea Social Accounting Matrix (SAM) follows IFPRI’s Standard Nexus SAM approach, by focusing on consistency, comparability, and transparency of data. The Nexus SAMs available on IFPRI’s website separates domestic production into 42 activities. Factors are disaggregated into labor, agricultural land, and capital, with labor further disaggregated across three education-based categories. The household account is divided into 10 representative household groups: Rural and urban households across per capita consumption quintiles. Nexus SAMs support the improvement of model-based research and policy analysis in developing countries and allow for more robust cross-country comparisons of national economic structures, especially agriculture-food systems.

Food Security Simulator – Papua New Guinea

Food Security Simulator – Papua New Guinea

The Food Security Simulator Papua New Guinea (FSS-PNG) is an innovative and easy-to-use, MS-Excel-based tool for assessing the potential short-term impacts of food price or household income shocks, along with changes in preferences, on food security and people’s diets. The Simulator is an ideal tool for first-cut forward-looking evaluations of direct, household-level outcomes of economic crises and policy responses in a timely manner. The tool allows users to enter positive and negative price or income changes in percentage terms and provides simulated changes for a diverse set of food-consumption- and diet-quality-related indicators. In addition to detailed tabular presentations of all simulation results by household income quintile and residential area, key indicator results are summarized in concise overview tables and visualized in graphs for easy export and use in reports. The underlying data include estimates from representative household survey data and rigorous, sophisticated food demand models to capture consumer behavior.

Papua New Guinea Rural Household Survey, 2023

Papua New Guinea Rural Household Survey, 2023

The Papua New Guinea Rural Household Survey (2023) collected detailed household-level data on agricultural production, food and non-food consumption and expenditure, and livelihood strategies across 14 provinces, covering communities in the highlands, lowlands, and islands of Papua New Guinea (PNG). The survey was designed using a purposive sampling strategy based on defined agro-ecological zones, which allows for the analysis of key factors influencing rural households and communities. It is important to note that the survey is not nationally representative; however, given the careful random selection of survey areas, we expect that generalizable relationships between variables affecting socio-economic and other development outcomes in rural PNG communities will be consistently observed across representative samples and in this survey. These factors include those that contribute to more resilient local food systems, diversified employment opportunities, and improved household wellbeing. The survey encompasses 2,699 households in 270 communities, spanning five agroecological zones. It features detailed modules on a wide range of topics relevant to rural livelihoods, agricultural production, and household wellbeing.
