The COVID-19 pandemic has impacted urban and rural households throughout Papua New Guinea (PNG). Looking ahead, policy makers and development practitioners must continue to mitigate COVID-19 impacts on PNG households, as well as monitor other potential agricultural production shocks (such as El Niño, African Swine Fever, etc.) that could substantially decrease household income and food consumption.
Our recent study simulates the impact of a suite of COVID-19 shocks on the PNG food economy, as well as a set of potential agricultural production shocks. The model is designed to evaluate how the impacts of these shocks differ by geographic region, income level, and rural or urban area. The COVID-19 pandemic has presented a challenge far more complex than an agricultural production shock; however, both COVID-19 and a variety of climate and pest-related risks continue to threaten the PNG agrifood economy.
Overall, these shocks disproportionately affect the poor; but the pandemic has a greater impact on those in urban areas, while other shocks fell more heavily on the rural poor.
To understand the impact of the simulated shocks on household welfare and food security, we must first estimate the current baseline income and food consumption trends. Figure 1 displays the estimated average calories per person per day calculated using the data from the 2009/10 Household Income and Expenditure Survey (HIES), considering the modest growth in agriculture per capita between 2009 and 2018.
Two important takeaways are shown in Figure 1:
Considering the average income and calorie consumption by household type, we design two sets of simulations to evaluate: (1) the impact of the COVID-19 pandemic; and (2) impacts of select agricultural production shocks. We summarize each in turn below.
Based on international price trends, conversations with international and domestic traders, and social distancing measures employed to curb the spread of COVID-19 in PNG, we designed the following simulations (results are discussed individually in this video presentation):
A final simulation calculates the combined effects of the above individual simulations. Results from the combined simulation suggest that urban households are particularly vulnerable to the impact of COVID-19 and related social distancing policies. Urban poor and non-poor households experience declines of 19.8% and 15.8%, respectively, in calorie consumption due to lower economic activity (urban job loss), increases in marketing costs, and increased imported rice prices (Figure 2). Rural households are affected less but still experience reductions in income and consumption within an already vulnerable socioeconomic environment.
Agricultural production shocks simulations
In contrast to the COVID-19 simulation results, the agricultural production shock simulations underline the vulnerability of rural households (representing more than 80% of the population). We simulate the following risks that are monitored by the PNG Department of Agriculture and Livestock Food Security Cluster:
Each of the above simulations result in a decline in household incomes across all household groups (rural, urban, poor and non-poor households) at the national level. Rural incomes fall because the decrease in agricultural production directly affects rural income. The negative effect on urban household incomes reflects a reduction in consumption (demand) for all goods, both agricultural and non-agricultural. Reduced demand leads to lower prices for non-tradable non-agricultural goods, which discourages production of these goods, and ultimately reduces urban incomes.
Production shocks also lead to reduced calorie consumption, particularly among rural households (Figure 3). Rural households’ calorie consumption falls sharply (by -3.7% in non-poor households to -5.5% in poor households) when production of sweet potatoes in the Highlands region declines (due to a simulated El Niño shock). Given that sweet potato is an important staple in the rural PNG diet, a drop in production on this commodity results in more acute reductions in calorie intake. Comparing the different simulations across household groups, rural households (both poor and non-poor) are particularly vulnerable to a significant El Niño (or La Niña) event or a major African Swine Fever outbreak.
Summary and policy implications
Urban households, especially the urban poor, in PNG are the most affected by the COVID-19 pandemic. Lower economic activity in urban areas, increases in marketing costs due to domestic trade disruptions, and 30% higher imported rice prices combine to lower urban incomes by almost 15%. Urban poor households suffer the largest drop in calorie consumption: 19.8%. Rural households are less affected by the COVID-19 related shocks modelled in these simulations. Nonetheless, calorie consumption for the rural poor and non-poor falls by 5.5% and 4.2%, respectively.
Agricultural production shocks (e.g., El Niño, pest infestation, African Swine Fever) have a larger impact on rural incomes and food consumption. A simulated 25% reduction in sweet potato production in the Highlands, as occurred in the 2015-16 El Niño event, leads to an average drop in total calorie consumption of 5.5% and 3.7% for the rural poor and non-poor, respectively. Given that over 80% of PNG’s population lives in rural areas, programs to increase rural household and community resilience to shocks and improve emergency assistance mobilization are needed.
