× Policy simulations utilizing an economy-wide model based on PNG national accounts and survey data highlight the importance of linkages between the agricultural and non-agricultural sectors of the PNG economy.
There are potentially major benefits of increased agricultural productivity for national income and urban households. To reduce rural poverty, however, transport and processing costs must be lowered, as well.
Even if only half of the increase in foreign exchange earnings from the 2022 world energy price shock is absorbed into the PNG economy, the real exchange rate appreciates by 13 percent, reducing incomes from export crops. However, increased domestic demand for non-tradable crops contributes to a 10 percent income gain for the rural poor.
Using a portion of increased oil and natural gas revenues to finance new investments in crop agriculture, processing and transport, provides even greater benefits by spurring real GDP growth and raising real household incomes by an additional 2 to 4 percentage points.
A hypothetical carbon credit arrangement in which PNG reduces deforestation in exchange for funds used to finance cash transfers to the poorest 20 percent of both urban and rural households could raise the incomes of these groups by about 13 percent.

× Understanding how the Papua New Guinea (PNG) agricultural economy and associated household consumption is affected by climate, market and other shocks requires attention to linkages and substitution effects across various products and the markets in which they are traded. In this study, we use a multi-market simulation model of the PNG food economy that explicitly includes production, consumption, external trade and prices of key agricultural commodities to quantify the likely impacts of a set of potential shocks on household welfare and food security in PNG.
In this study, we use a multi-market simulation model of the PNG food economy that explicitly includes production, consumption, external trade and prices of key agricultural commodities to quantify the likely impacts of a set of potential shocks on household welfare and food security in PNG. We have built the model to be flexible in order to explore different potential scenarios and then identify where and how households are most affected by an unexpected shock. The model is designed using region and country-level data sources that inform the structure of the PNG food economy, allowing for a data-driven evaluation of potential impacts on agricultural production, food prices, and food consumption. Thus, as PNG confronts different unexpected challenges within its agricultural economy, the model presented in this paper can be adapted to evaluate the potential impact and necessary response by geographic region of an unexpected economic shock on the food economy of the country.
We present ten simulations modeling the effects of various shocks on PNG’s economy. The first group of scenarios consider the effects of shocks to production of specific agricultural commodities including: 1) a decrease on maize and sorghum output due to Fall Armyworm; 2) reduction in pig production due to a potential outbreak of African Swine Fever; 3) decline in sweet potato production similar to the 2015/16 El Niño Southern Oscillation (ENSO) climate shock; and 4) a decline in poultry production due to COVID-19 restrictions on domestic mobility and trade. A synopsis of this report, which focuses on the COVID-19 related shocks on the PNG economy is also available online (Diao et al., 2020).1
The second group of simulations focus on COVID-19-related changes in international prices, increased marketing costs in international and domestic trade, and reductions in urban incomes. We simulate a 1) 30 percent increase in the price of imported rice, 2) a 30 percent decrease in world prices for major PNG agricultural exports, 3) higher trade transaction costs due to restrictions on the movement of people (traders) and goods given social distancing measures of COVID-19, and 4) potential economic recession causing urban household income to fall by 10 percent. Finally, the last simulation considers the combined effect of all COVID-19 related shocks combining the above scenarios into a single simulation.
A key result of the analysis is that urban households, especially the urban poor, are particularly vulnerable to shocks related to the Covid-19 pandemic. Lower economic activity in urban areas (assumed to reduce urban non-agricultural incomes by 10 percent), increases in marketing costs due to domestic trade disruptions, and 30 percent higher imported rice prices combine to lower urban incomes by almost 15 percent for both poor and non-poor urban households. Urban poor households, however, suffer the largest drop in calorie consumption - 19.8 percent, compared to a 15.8 percent decline for urban non-poor households. Rural households are much less affected by the Covid-19 related shocks modeled in these simulations. Rural household incomes, affected mainly by reduced urban demand and market disruptions, fall by only about four percent. Nonetheless, calorie consumption for the rural poor and non-poor falls by 5.5 and 4.2 percent, respectively.

× Public food transfer program provide a lifeline for the poor in both high- and low-income countries, and many countries stepped these up in response to COVID-19. But little is known about how effective these programs have been in reaching the poor during the crisis. This brief reviews the findings of an evaluation of Bangladesh’s Food Friendly Program, pointing to the difficulties encountered during the pandemic and lessons to help these program perform better in future crises.

× Provision of food safety requires not only regulation but also a demand pull where value chain participants demand food safety or are able to play their role in providing safe food. In both cases, producer, and consumer awareness about requirements for food safety is a precondition for delivery of food safety. In this paper, focusing on dairy in Sri Lanka, we assess the awareness and choice of practices by producers and consumers towards food safety. Sri Lanka has unique features in the dairy sector, with very high import penetration and form of consumption, i.e., powdered milk, that actuates formalization.
Looking at different segments of the population, including rural, urban and estate, and different management systems, the evidence suggests only a moderate level of food safety awareness in dairy in middle-income consumers in Sri Lanka. Considering the differences across systems, the degree of adoption of food safety is lowest among farmers in the extensive system, while it is highest among farmers in the intensive system. However, in terms of choice between powdered and fresh milk, food safety consciousness is one of the most significant determinants where fresh milk is considered comparatively unsafe.
Even when food safety issues arose in powdered milk, only small adjustments occurred in consumption, both because the health effects were limited, and the choice sets were circumscribed by the number of brands across which some consumers switched following the food safety scare. In the push toward promotion of fresh milk consumption, ensuring food safety and convincing consumers about merits of fresh milk would be required in Sri Lanka beyond the preference change from well-established powdered milk consumption.

× This study, based on a primary survey conducted in Bangladesh in 2016, assesses the impact of contract farming in broiler production on profits and the adoption of food safety measures at the farm level. It also estimates the determinants for participation in contract farming, finding a farmer’s education and broiler-housing structure to be significant determinants. This study uniquely assesses the association of contract farming with the provision of well-defined food safety attributes. It finds that contract participation enhances farmers’ net returns by as much as 215–280% and raises compliance with food safety measures by around 13%. Increased productivity and provision of non-price attributes such as food safety in the product account for the difference in farmer returns.

× The onset of the COVID-19 pandemic has presented a unique challenge to governments across the globe, reinforcing the need to improve understanding of domestic and international trade trends to provide more informed options for policy response. During the last several months, IFPRI has been analyzing a variety of Papua New Guinea (PNG) national and global datasets with the goal of expanding analytical tools to evaluate potential production shortfalls and food price shocks, and their associated impacts on household food security and livelihoods. This research note focuses on agri-food import and export trends during the last two decades to better evaluate potential changes in related import demand and export potential in PNG. In doing so, this research note informs an upcoming economy-wide multi market model analysis that will model a variety of potential shocks to household welfare to identify policies to manage potential ensuing food security threats.
PNG’s growth in international agri-food trade (both export and import) will continue to be important to overall food security outcomes among rural and urban households. Rural households that produce key export cash-crops (e.g., coffee, cocoa, palm oil) depend on the cash economy to supplement overall food consumption, while urban households depend on rice and other agri-food imports (as well as domestic goods) for consumption. Agri-food imports are also contributing to important increases in the availability of protein-dense foods, with the value of poultry imports growing, on average, 30 percent per capita per year from 2001 – 2016. Although PNG’s agri-food import data suggest a greater demand for higher value food items such as animal-sourced foods, the total import value of ultra-processed foods, such as sugary drinks, are also increasing rapidly within PNG.
The profitability and growth of agricultural exports and imports are driven by several factors, including levels of public investment in infrastructure, weather and climate shocks, security and political stability, and conditions in the world market. Government economic policies, including exchange rate, trade and price policies, also heavily influence agricultural trade. Policy to promote and facilitate domestic movement of goods, as well as macro-economic policies that influence the relative price of tradable to non-tradable goods (the real exchange rate) should be managed appropriately to support and incentivize greater agri-food production and trade. These policies could also be paired with an expanded set of education programs that integrate nutrition-sensitive information to address current increases in demand and consumption of high-saturated and sugary processed goods, of which total import values are rapidly increasing in PNG. Finally, a greater portfolio of organized databases, analytical tools and policy resources are warranted to facilitate real-time policy analysis that can inform key development investments and initiatives.

× Developments in the agricultural economy of Papua New Guinea have major impacts on household food consumption decisions. A household’s ability to produce and sell food is affected by climate and associated agricultural potential, market opportunities (domestic, import and export) and unexpected shocks. Each of these factors affects the overall food system, thereby influencing production and consumption of all food products and the markets in which they are traded. The COVID-19 pandemic has presented a challenge far more complex than an agricultural production shock, such as those due to El Niño or pests. Rather than directly affecting agricultural output and rural household welfare, the COVID-19 pandemic has affected economies across the globe via trade disruptions (logistic challenges; international trade barriers), social distancing policies (domestic food market and nonessential business closures), and transportation restrictions (road closures; air travel cancellations). The measures aimed to curb the spread of COVID-19 have affected household incomes via urban job losses, reduced market interaction, and dramatic changes in world food prices. While rice prices have increased, luxury food prices, such as for chocolate (i.e. cocoa), have decreased. PNG’s unique and highly varied biophysical landscape has shaped agricultural production patterns, outcomes, and livelihoods for centuries. Understanding how the PNG agrifood economy and resulting household consumption is affected by COVID-19 therefore requires attention to linkages and substitution effects across various products and the markets in which they are traded.

× This paper aims to provide a better understanding of Myanmar’s agricultural export performance against its competitors in different regions and determine the policy actions for improving Myanmar’s export performance. The normalized revealed comparative advantage (NRCA) index is computed to compare the agricultural competitiveness between Myanmar and its competitors from 2007 to 2016. The results show that: 1) Myanmar’s agricultural export sector enjoys comparative advantage in the global market, but it is not competitive when compared with its major competitors; 2) Myanmar reveals a high level of NRCAs in black gram & pigeon peas, natural rubber, sesame seeds, rice, and frozen fish, while it has low NRCAs in crustaceans and dried fruits; and reveals no comparative advantage in bananas, fish fillets, maize, nuts, and watermelon in certain years. Three major policy implications are drawn, including diversifying Myanmar’s export portfolio, strengthening export promotion and development, and attracting foreign direct investment to upgrade the cross-border value chain.

× Since 2012/13, rice exports to China (which may have reached two million tons in 2015/16) boosted total demand for Myanmar’s rice and rice prices. In mid-2016, however, China stopped rice imports through the main land entry point, putting substantial downward pressure on prices. Analysis presented in this paper, based on econometric estimates of consumption parameters and a simple model of Myanmar’s rice supply and demand, suggests that market prices would fall by 26 to 43 percent or more (in real terms) in the absence of increased exports to the world market and/or government domestic procurement. Such a decline in prices could have seriously harmed Myanmar’s rice producers, including many poor farmers with marketable surpluses. Model simulations suggest that government procurement of about one million tons would limit the estimated price decline to only 17 to 30 percent. Further refinements in the simulations are needed to take account for the seasonal nature of paddy production in Myanmar, possible price-responsiveness of export demand and the effects of changes in paddy incomes on farmer demand for rice. Medium-term analysis of procurement, storage and future sales is needed to analyze fiscal costs under various scenarios, as well, covering alternative shocks to production, export demand and world prices. Nonetheless, the main results are clear: without substantial market interventions on the order of one million tons (milled rice equivalent), the paddy (rice) price could fall dramatically when production increases or export demand declines.

× Contract farming is emerging as an important institutional innovation in the high value food chain in developing countries including Bangladesh, and its socioeconomic implications are topic of interest in policy debates. This study is an empirical assessment to explore the determinants of participation and the impact of contract farming on welfare and adoption of food safety practice in Bangladesh. Our analysis indicates that contract farmers are more likely to have better access to agricultural extension services, attended proportionately more community meetings, households members are member of organizations, access more credit, are located farther from output market, and have larger herd sizes. We also find that network variables such as time spent with cooperatives and other institutions and price fluctuation and average prices received experience before participation in contract are strongly associated with participation in contract farming. We find that contract farming has a robust positive impact on welfare measured by expenditure, farm profit and farm productivity, and food safety practice adoption even after innovatively controlling for observed and unobserved heterogeneity among dairy farmers. More specifically results indicate that a one unit increase in the likelihood of participating in contract farming is associated with a 42, 35,34 and 9 percent increase in household expenditure, gross margin and net margin per cow, and food safety practice adoption rate respectively, among other positive impacts.

× Fish play a major role in the Bangladesh food system. Fish production, processing and marketing are major source of incomes for many households, and fish consumption accounts for a significant share of protein consumption in the Bangladeshi diet. Moreover, fish production and consumption are growting rapidly, with the aquaculture subsector as a major driver of change of both supply and demand. In this paper, we present estimates of demand elasticities for four categories of fish (aquaculture, inland capture, mixed production, and marine) using a modified Quadratic Almost Ideal Demand System. These demand estimates are then used in projections of future supply and demand for these different types of fish under different productivity growth assumptions. Our results show that, at current rates of productivity increase, growth in fish production will outpace increases in demand from population and income growth, resulting a decline in real prices over time. A more rapid increase in productivity would lead to even larger supply increases and corresponding price declines. These effects are most keenly felt by the poorest households who see significant increases in fish consumption. Fish production from aquaculture is likely to have higher rates of productivity growth than the more extensive inland capture and marine systems, leading to a long term shift increase in the share of aquaculture production and consumption.

× Indonesia has managed to combine high rates of growth, rapid reductions in rural poverty and a significant structural transformation of its economy all at the same time without a big increase in urban manufacturing. Agriculture was a critical part of this transformation through two important channels. First, export-oriented agriculture, particularly palm oil and rubber contributed to rising foreign exchange receipts and helped make compatible rapid growth without balance of payments pressure on the macro economy. Second, through the release of workers from low productivity agriculture to more productive nonagricultural activities, structural change contributed between 25 and 50 percent of the rise in national labor productivity depending on the period. The government also played an important role in agricultural development and productivity growth. Public investments in irrigation in combination with subsidies for fertilizer and improved seeds increased agricultural productivity generating an adequate supply of food for domestic needs with less labor.

× Vietnam has experienced rapid growth in agricultural mechani-zation lately; particularly in the use of tractors and combine-harvesters. A recent IFPRI study documented the evolution of the growth of mechanization in Vietnam based on an extensive review of the existing literature and several rounds of a nationally repre-sentative household survey. The level of tractor use in Vietnam was relatively high in the 1970s and the early 1980s but declined through the late-1980s before it started taking off again in the 1990s. The relatively high level of tractor uses up to the early-1980s were partly due to political and military reasons, as both the West and the Soviet Union gave substantial support in providing heavy machinery, including tractors. In this note, we focus on the evolution of mechanization from 1990s to 2000s.

× Despite the reportedly rapid growth of mechanization, as well as its unique history in economic and social systems, information on the patterns of agricultural mechanization growth in Vietnam has been limited. Through an extensive review of existing literature and several rounds of nationally representative household survey data, we document the evolution of mechanization (particularly tractors and combine harvesters) in Vietnam, including the heterogeneity across regions and farm sizes, and the emerging roles of the private sector in the supply of machinery and hiring services.

× This paper focuses on rural nonfarm development via the route of salaried employment. The analysis is at the rural household level for two types of households: “mixed” households whereby some workers remain in the farm sector and others pursue nonfarm activities and the rural households who are exclusively dependent on nonfarm employment (rural nonfarm). The study has produced three major findings. First, compared with the mixed or farm-only households, nonfarm households seem to have more income. Second, nonfarm households discourage unpaid work, especially among female workers, in sharp contrast to the increasing share of unpaid work in both farm and mixed households. Third, nonfarm households increasingly rely, for their livelihoods, on salaried employment, which is likely to be of a more durable nature than the juggling of multiple occupations observed in the case of mixed households. Analysis of possible factors influencing the formation of nonfarm households shows the importance of human capital, non-land assets, and proximity to larger towns, while natural shocks seem to encourage the formation of mixed households and remittance from abroad tends to stimulate the farm orientation.

× In September 2015, Nepal’s Constituent Assembly passed a new constitution aimed at transforming Nepal from a unitary country into a federal republic with three levels of government: the federation, the province, and the local level. This institutional shift will have wide-ranging social, political, and economic implications for the country. However, this brief focuses specifically on the implications of these federal reforms for the agricultural sector and the Ministry of Agriculture (MoAD). Agriculture is the backbone of the Nepali economy, providing a livelihood for approximately two-thirds of the population, contributing one-third of the country’s GDP, and constituting over half of its exports. With greater authority and autonomy granted to more subnational units of government, ensuring that the agricul-tural sector is guided by coordinated planning, retains sufficient human capacity, and receives adequate fiscal resources will be of para-mount importance during the transition to a federal republic. Consequently, this brief addresses how the sector can be restructured to meet the constitutional provisions while simultaneously ensuring that MoAD delivers on its agricultural objectives, especially those out-lined in its Agricultural Development Strategy (ADS).

× The Thai broiler industry is an innovative and successful story of transformation from a traditional “backyard” production system to a fully industrialized agri-industry. It is among the first agricultural products in Thailand that developed into a modern value chain that is fully integrated and able to expand its production to keep prices in check whilst making chicken the go-to source of protein. Highlighted by its expansion into regional and global markets through trades and investments, the success of the industry is largely a result of strong and visionary business models that calculated risks yet were clear on their objectives on how to secure emerging markets. This paper describes the development of the Thai broiler industry, documenting its path and reasons behind its success. Focus is particularly placed on the Thai industry’s leader, Charoen Pokphand Group (C.P.), and its business decisions over the years that enabled the company to gain a foothold in the highly competitive international market for chicken meat.

× The paper argues that much of the farm-nonfarm labor mobility in rural Bangladesh is in nature an intergenerational occupational choice-induced change rather than a sectoral shift within the current generation. Bangladesh has a large share of youth (aged 15-29 years) in the labor force, and it experienced a major structural shift in employment between 1995 and 2010 as agricultural employment fell from 51.4 percent to 42.3 percent. Much of this shift has been due to changes in youth employment, as youth employment in agriculture fell from 49.8 percent to 33.1 percent. The cohort analysis (pseudo-panel) shows that the reduction in the share of male youth population working in agriculture is due mainly to a sharp reduction in the percentage of youth who start out in agriculture, rather than a shift by individuals from agricultural to non-agricultural employment during their life time. Analysis of correlates of the non-farm orientation of rural youth indicates the importance of gender, human capital, access to electricity, proximity to cities, and migration opportunities. The results suggest the importance for supporting rural industry and service activities for meeting the future demand of jobs for the rural youth.

× This review evaluates the role of the state in development, offering a new framework for understanding what capabilities states need to overcome different types of market failures. This framework is employed to understand the successes and failures of state-led development in Malaysia. The review addresses three key questions. First, what do we know about developmental states and why they emerged? Second, what have developmental states achieved? In answering this question, I look not only at growth but also at structural transformation, economic “upgrading,” equity, and human capability enhancement. In contrast to the idea of a single “East Asian model” of development, I find five distinct development trajectories. Third, how did developmental states utilize state structures to pursue development? To answer this final question, I examine in depth the history of state-led development in Malaysia—including agricultural, industrial, and social policies. This case study sheds light on what specific institutional and political capacities helped Malaysia to improve productivity in agriculture, expand the manufacturing sector, and reduce inequality. It also explores why Malaysia has been less successful in developing linkages with the export-based manufacturing sector.

× This paper examines the fertilizer subsidy program in Nepal from two different angles, both important for policy makers in the country. First, it analyzes who is benefiting from the program, and second, it examines how farmers rank the importance of public spending on fertilizer subsidies compared with other potential public investments. Whereas the former question is important for judging whether the program is meeting its objectives, the latter is essential to understanding the scope for reform, in particular the extent to which we could expect citizens to resist reforms to the subsidy program. We draw on these analyses as well as on examples from other countries to make policy recommendations to improve program implementation.

× In this paper we explore the implications of Nepal’s new federal Constitution—passed in September 2015—for governance of the agricultural sector. Agriculture is the backbone of the Nepali economy, providing a livelihood for approximately two-thirds of the population, contributing one-third of the country’s GDP, and constituting more than half of the country’s exports. In transitioning from a unitary to a federal republic—with greater authority and autonomy granted to subnational units of government—it is of paramount importance to ensure that the agricultural sector is guided by coordinated planning, retains sufficient human capacity, and receives adequate fiscal resources. These considerations are particularly important given that the governance of Nepal’s agricultural sector already suffers from poor coordination, low human resources capacity, and inadequate financial resources. Addressing these issues may become more difficult under a federal structure. This paper begins by laying out the main challenges for agricultural governance in Nepal under the current structure. To do so, it relies on an original survey of 100 district agricultural and livestock officers in charge of local agricultural service delivery in Nepal as well as perspectives collected through more than two dozen semi-structured interviews with officials from the Ministry of Agricultural Development, the Ministry of Livestock Development, civil society, the private sector, and donors. Because Nepal is embarking on a pathway to more decentralized governance, which has been well-trodden by a number of other countries, the paper proceeds by examining five case studies, drawing lessons from India, Indonesia, Kenya, Malaysia, and South Africa. Based on these analyses, the paper offers policy recommendations on how the sector can be restructured to meet the constitutional provisions, while simultaneously ensuring that the government can deliver on its long-term objectives to develop the agricultural sector.
