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).

Papua New Guinea food price bulletin: April 2026

This bulletin reports on food price trends from major markets in Papua New Guinea (PNG), for the first quarter (Q1) of 2026 using the data collected by Fresh Produce Development Authority (FPDA). During the first quarter, at least one round of data per month was collected from all markets, except for Port Moresby in February (no data). In March, Banz and Port Moresby had two rounds each, while all other markets had one round. This report analyzes month-over-month changes in Q1 2026 (January to March) and compares prices with the previous quarter (Q4 2025: October to December) and the same period in 2025 (Q1 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 March 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 (aibika, English cabbage, capsicum, carrot, and choko-tips) and fruits (lemon, orange, pawpaw and pineapple).

Creating a taro yield emulator and using it to study climate change impact on taro in Papua New Guinea

This paper develops a taro yield emulator to assess climate change impacts on taro production in Papua New Guinea (PNG). The emulator uses a fixed-effects polynomial regression trained on DSSAT simulations to capture non-linear, stage-specific responses of taro yields to rainfall and temperature. Historical MSWX weather and future climates from CMIP6/ISIMIP3b and a large MIT-IGSM/AgERA5 sample are used to drive the emulator and assess changes in average yields, yield variability, and the frequency of low-yield years across PNG. Our analysis shows that taro appears to be sensitive to both low- and high-rainfall levels during particular phases of growth and is sensitive to heat during particular phases, as well. Our visit to farmers fields in the Markham Valley along with discussions with experts at GrowPNG in Lae, NARI, and PNG University of Technology in Lae alerted us to the fact that drought was a serious problem for taro, but the model revealed the additional issues with high rainfall and high temperature, along with the additional information about the months that were particularly important for determining the degree of damage that adverse weather might do to yields. National-average yield changes by mid-century under high-emissions scenarios are projected to be small based on the median projections across climate models, however one of the climate models projects a much larger temperature increase relative to the other models, and for that climate model, the yield reduction is around 9% on average.
