Agricultural Mechanization Services Rice Productivity And Farm Plot Size Insights From Myanmar

The relationship between productivity and farm size has been at the center of considerable debate. Agricultural mechanization – that is rapidly taking off in a large number of low- and middle-income countries – has been identified as one of the emerging technologies in these settings with a critical, yet complex, influence on this productivity-size relation. However, knowledge gaps remain as how agricultural transformation due to the adoption of new technologies and the change in factor costs, such as mechanization fees, are associated with this productivity - size relation. In the case of Myanmar, where mechanization use has dramatically increased over the last decade, we find a significant inverse productivity - plot size relationship, with small rice plots having productivity levels approximately 30 percent higher than large plots. However, rising mechanization fees – more so in conflict-affected townships – attenuated this inverse relation between rice productivity (yield and profit per land) and plot size substantially. These results primarily hold on the largest rice plot cultivated by each farmer, but also generally hold when comparing total rice area and major non-rice area. Our results are likely explained by the fact that, in Myanmar, smallholders have become more dependent on mechanization services than larger farms (who can rely on their own machines) do, that alternatives to mechanization services have become scarce (as mechanization use changed little, despite these price increases), and that mechanization service costs account for a significant share of the total production costs among smallholders.

A phone survey was conducted in January 2023 to understand the effects of COVID‑19 and political instability on Myanmar’s mechanization service providers (MSPs). MSPs are crucial to enabling smallholder farmers to undertake a range of power-intensive farm and post-harvest operations in a timely manner. This note reports on the results of this survey, the tenth in a series of phone surveys, and trends from earlier surveys.

This study explores the transformation of Myanmar’s rice value chain (VC) over a period of liberalization, reform, and infrastructure expansion from 2013 to 2019, and over a period of multiple crises from 2020 to 2022 including a military coup and widespread conflict. We analyze modernization over these periods at different levels of the VC, including upstream (farms), midstream (mills), and downstream (rice vendors). We rely upon unique data from large-scale phone surveys collected at different segments of the rice value chain – including farm and post-farmgate – complemented with insights from key informant interviews, and secondary data. The major findings are the following: There have been large transformations within the rice value chain over the last decade, but modernization in some areas decelerated due to conflict. We note a process of modernization, upscaling, quality improvements, and increased outsourcing of agricultural activities to specialized service providers by farmers. The majority of this transformation occurred during the period of relative stability from 2013 to 2019. We show that although modernization continued during the crisis years that followed, including an improvement in rice quality and an expansion of modern mills, many modernization processes decelerated. Mills and farms in insecure and conflict-affected areas participated to a lesser extent and the modernization gaps widened during the crisis years. Local rice market conditions improved with better-quality rice sold locally. A large share of food vendors indicated better rice quality overall at the time of survey compared to 3 and 10 years earlier. Sixty-eight percent of vendors reported that there was no foreign matter in the rice that they sold a decade ago. That share has increased by 23 percentage points to 91 percent in 2022. In domestic retail, modern retail is (yet) negligible in rice distribution at the national level. Rice exports quadrupled, with Myanmar becoming globally the 5th biggest exporter of rice by the end of 2019. Rice exports have proven to be resilient during the crisis years. Rice exports increased dramatically despite more stringent, and costly, non-tariff measures for exports such as phyto-sanitary requirements. Rice is exported through different channels, moving away from low-quality rice trucked to China, to relatively better-quality and often certified rice being shipped on large vessels to a more diverse set of countries. We see shifting challenges over time – due to banking, electricity, and mobility problems that millers and traders adjusted to, at an increasing cost – but national exports mostly stabilized, in the crisis years compared to the period before, seemingly as major rice producing areas - except Sagaing - were less affected by conflicts, Midstream, we see rapid uptake and investments in modern drying machines – especially mechanized dryers – and modern milling machinery in the form of new mill starts and upgrading from traditional mills. The average number of modern mills operating in the miller’s same village tract/ward increased by about 60 percent from 2013 to 2019 and by a further 10 percent in 2022. The trend for traditional mills is the opposite: declining by 50 percent between 2013 and 2019 and a further 15 percent in 2022. This modernization has been driven by local firm investments as Foreign Direct Investment (FDI) has been limited. Upstream (at the farm level), we note a substantial expansion of modern input use. Rice seed markets have become more active in the 2010s. The sale of branded rice seeds doubled over the last decade. Chemical fertilizer use also increased over the last decade. While use was lower in 2022 than before the crisis, they were still at a higher level than a decade earlier. We also see increased use of modern harvest and post-harvest technologies and more outsourcing of harvest and post-harvest activities, mostly linked to these modern technologies and practices. In 2022, 54 percent of the farmers reported to have used a combine-harvester on most rice plots. Farmers hiring in tractors increased by 33 percentage points over the last decade. Outsourcing drying services has also increased, but the growth has been more modest: 22 percent of the farmers indicated that they outsourced the drying of paddy. Modern dryer use increased accordingly. We find significant negative relationships between severe local conflict and many modernization outcomes. Severe conflict is found to negatively impact various modernization aspects, notably the adoption of tractor services and modern dryers at the farm level, and the prevalence of modern mills and drying equipment in midstream operations. Modernization has not been everywhere inclusive. More remote and smaller firms are participating less in modern practices. More remote farmers show smaller growth in adoption of combine harvesters, modern dryers, and modern mills, while smaller farmers have smaller growth in the use of combine harvesters and drying service providers. In the midstream, mills in remote areas show smaller changes in the share of modern mills in their areas, while smaller mills have significantly slower growth in modern service provision and lower investment rates in value-added machinery. For many of these modernization outcomes, the gaps across firm size and remoteness widened during the crisis years. Our findings point to three main implications for the modernization of Myanmar’s rice VC. Private-market oriented reform leads to rapid modernization in VCs, while heavy intervention – e.g., low reference prices for rice; limits on intranational trade; control of imports and exports through an export licensing system; and currency manipulation through a dual exchange rate system – may jeopardize VC modernization and increase uncertainty throughout VCs. More inclusive transformation should be promoted. Smaller and more remote farms and mills are showing slower growth across many modernization outcomes, raising concerns about livelihood improvements for those participating less in the VC’s modernization. Conflict negatively affects modernization at the farm and VC midstream. The study reaffirms the crucial need for stable political and economic environments to foster effective agricultural growth and transformation.

Key Findings We analyze paddy rice productivity and profitability data for the dry seasons of 2022 and 2023, based on the Myanmar Agriculture Performance Survey (MAPS) fielded in the period of June 26th to July 25th, 2023. The survey covered plots of 659 rice paddy producers. It is found that: • Prices of inputs used in paddy production – fertilizer, labor, mechanization – increased between these two growing seasons by between 13 and 21 percent, on average. On the other hand, paddy prices at the farm increased by 68 percent. • Real profits, with nominal prices corrected by the change in the cost of an average food basket, from paddy rice farming during the dry season of 2023 increased by 41 percent compared to the dry season of 2022. While nominal profits for paddy rice farmers increased by 70 percent over the last two seasons, price inflation has been high in the country and real profit increased therefore much less. • Rice farmers increased input expenditures on paddy production by 50 percent compared to last year. However, larger farmers invested more and doubled input expenditures, likely attracted by the increased profits in paddy farming. • Rice productivity at the national level during the dry season of 2023 on farmers’ largest rice plot was slightly larger (+1.2 percent) than in the previous dry season. Substantial declines are noted in the coastal areas (-29 percent) and the Dry Zone (-5 percent), possibly linked to impacts of cyclone Mocha. • Thirteen percent of all crop farmers reported to have been affected by the cyclone Mocha and 3 percent of the crop farmers indicated that they lost their whole dry season harvest. Almost half of the affected farmers reported that the next monsoon season would not proceed as normal, likely affecting the production of rice – and other crops – in those areas during the next monsoon season. Recommended Actions • As paddy prices have gone up significantly, rice prices have gone up substantially as well, making the costs of Myanmar’s staple food unaffordable for some consumers, especially for the most vulnerable ones. Expansion of safety nets, targeted or self-targeted to the poorest, would therefore be beneficial. • The cyclone Mocha has destroyed harvests of farmers in Rakhine and part of the Dry Zone. As effects of the devastation of the cyclone will continue to be felt during the monsoon of 2023, further assistance for farmers in these areas to recover from these effects is called for.

Evidence is scarce on how conflict affects technology adoption and consequent agricultural productivity in fragile states, an important topic given the high share of the extreme poor living in fragile environments globally. Our study contributes to filling this knowledge gap by using unique large-scale data on rice producers in Myanmar before and after a military coup in 2021, leading to a surge of conflicts in the country. We find that the increase in violent events significantly changed rice productivity. Specifically, increases in fatal violent events between 2020 and 2021 reduced rice Total Factor Productivity (TFP) – a measure of how efficiently agricultural inputs are used to produce rice – by about 4 percent on average in the short-run. Moreover, poorer farmers are more affected by conflict, as seen through an increased output elasticity to agricultural equipment owned, indicating reduced output resilience for less-capital owning, and therefore poorer, farmers. This seems partly due to reduced access to agricultural extension services, which would otherwise help farmers maintain productivity, even with limited capital ownership, through substitution with human capital and skills. Lower mechanization service fees partly mitigate these effects. Our results consistently hold for both short- and long-run production functions, across various specifications, and in Upper and Lower Myanmar. These findings suggest that containing and reducing violent events is critical in restoring rice productivity. Improved access to extension services, as well as to cheap mechanization service provision to mitigate lack of equipment ownership, could compensate for these losses and boost the productivity of farmers, especially for those with less production capital, in such fragile settings.

We have analyzed rice productivity and profitability data for the 2023 monsoon season from the Myanmar Agriculture Performance Survey (MAPS), conducted at the beginning of 2024. This survey encompassed plots managed by 2,840 rice producers, distributed across all states/regions of the country. Our findings reveal: 1. National rice productivity exhibited an average increase of 7 percent during the 2023 monsoon compared to the previous year, reversing the decline witnessed in the 2022 monsoon. This year's heightened productivity primarily stems from increased input usage (particularly fertilizer), greater labor inputs (with more farmers adopting transplanting), and reduced occurrences of natural shocks, notably droughts. 2. The Ayeyarwady region, the country's principal rice-producing area, experienced an 11 percent increase in rice productivity. Conversely, rice yields remained low in Kayah and Chin, two states affected by severe conflict. The highest yields, along with notable increases over the past three years, are observed in Nay Pyi Taw. 3. Significant changes in input costs for rice cultivation were observed between the two seasons: 3.1 Prices of urea, the most important chemical fertilizer used by rice farmers, decreased by 16 percent. 3.2 Mechanization costs surged by a notable 42 percent, which is concerning, especially in light of escalating rural labor scarcity. Particularly pronounced increases in mechanization costs were noted in coastal areas where fuel prices were high, or fuel was not available at all. 4. Substantial changes in technology adoption and input utilization compared to the previous monsoon were noted: 4.1 Fertilizer use on rice increased by 20 percent. 4.2 Use of self-preserved seed – instead of obtaining it from the market - increased by 6 percentage points compared to last monsoon, and 17 percentage points compared to 2020. 4.3 Transplanting increased by 5 percentage points while broadcasting declined by 7 percentage points. 4.4 The use of combine harvesters on rice was 1 percentage point lower compared to last year but was 12 percentage points lower than in 2020. 5. Thirty percent of paddy farmers reported being impacted by climatic or other production shocks during this monsoon, with floods (reported by seven percent of farmers) and droughts (reported by five percent) having significant adverse effects on yields. When affected, paddy yields decreased by 32 and 51 percent, respectively. Incidences of pests, diseases, and weeds have the highest frequency overall (13 percent). 6. Substantial changes in input usage and technology adoption were observed in paddy cultivation within coastal areas (Rakhine and Tanintharyi), seemingly linked to insecurity, mobility constraints, and fuel accessibility issues: 6.1 Fertilizer use declined by one-third. 6.2 The utilization of combine harvesters plummeted by 26 percentage points. 7. Paddy prices at the farm level surged by 64 percent, reflecting changes in international rice prices as well as the depreciation of the MMK. 8. Real – in terms of the cost of an average food basket – profits from rice farming during the monsoon of 2023 increased by 43 percent compared to the previous year. While nominal profits doubled since the previous monsoon, high price inflation tempered the increase in real profits. 9. The paddy sector has proven resilient in 2023, with improved pricing incentivizing farmers to intensify production through increased usage of chemical fertilizers and labor inputs. The outlook for paddy production in 2024 appears promising yet uncertain due to the following factors: 1. Weather conditions: Adverse weather, as witnessed during the 2023 monsoon, can significantly impact yields. Most models predict the El Niño conditions - with drier-than-average rainfall conditions - to continue weakening. 2. Evolution of insecurity: Insecurity correlates with reduced access to inputs and, when accessible, higher costs, thereby lowering profitability for farmers. 3. Labor scarcity: Labor availability is expected to become increasingly constrained in the next monsoon due to significant out-migration linked to the Military Service Law. 4. Fuel availability: A quarter of Myanmar's farmers reported limited access to fuel during the post/pre-monsoon season of 2024, complicating irrigation, and agricultural mechanization, which is typically relied upon by most rice farmers. These findings underscore three primary implications for Myanmar's rice sector: 1. Ensuring adequate access to mechanization for rice farmers: Despite benefiting from increased mechanization over the past decade, there is a concerning trend of dis-adoption in combine harvester usage, attributed to mobility issues and fuel accessibility problems. This is particularly worrisome given the anticipated rise in rural labor scarcity. 2. Emphasizing access to climate-resilient seeds: While farmers are increasingly relying on self-preserved paddy seeds, there is a pressing need for the adoption of improved, high yielding, and stress-resistant varieties. As evidenced by our results, farmers affected by floods and droughts experience significantly lower yields than unaffected farmers. Given an expected increase of weather shocks, higher adoption of adapted seeds is required. 3. Addressing the impact of high rice prices on food security: While beneficial for farmers, elevated paddy prices contribute to high rice prices in the country, posing a significant concern, especially for the most vulnerable segments of the population.2 The most effective means of mitigating the adverse effects of high rice prices on poor consumers is through expanded safety net programs, providing additional liquidity directly to them.

We analyze rice input and productivity data for the monsoon seasons of 2020 and 2021 from the Myanmar Agriculture Performance Survey (MAPS). The survey covers plots of 2,672 rice producers, spread over 259 townships in all states/regions of the country. We find that: 1. Rice productivity at the national level during the monsoon of 2021 decreased on average by 2.1 percent compared to the monsoon of 2020. Considering estimated area reductions, national paddy production decreased by 3.4 percent compared to the monsoon of 2020. 2. Some areas performed substantially worse. Rice yields were low and declined significantly in Kayah and Chin, two conflict-affected states that have shown the highest levels of food insecurity in recent assessments. 3. Prices for most inputs used in rice cultivation increased significantly between these two seasons. Prices of urea, the most important chemical fertilizer used by rice farmers, increased by 56 percent on average and mechanization costs increased by 19 percent. 4. Paddy prices at the farm increased by 8 percent, significantly less than input prices, squeezing rice farmers’ profits during the monsoon of 2021. Despite the substantial hurdles in production and marketing due to the political crisis and international market developments, the results of the Myanmar Agricultural Performance Survey show the overall resilience of rice production during the monsoon of 2021. While the rice sector has been a source of stability in the country, the situation for future crop seasons is however concerning given further increases in input prices (especially fertilizer), the overall reduced profitability of rice farming, the reduced coping strategies remaining for rice farmers, and currency policy changes by the military government.

This research was undertaken to better assess the role of mechanization in the future of smallholder farmers in Nepal. It addresses the knowledge gap about whether promoting mechanization that is often complementary to land can effectively support smallholders, particularly in the face of a growing nonfarm sector. Rising rural wages in Nepal have increasingly put pressures on smallholder farmers, who tend to operate labor-intensive farming. Agricultural mechanization through custom hiring of tractor services has recently been considered as an option to mitigate the impact of rising labor costs for smallholders. However, the benefit of agricultural mechanization may still be better captured by exploiting the economies of scale of medium to large farmers rather than smallholders. In the meantime, the Nepal agricultural sector still employs a disproportionate share of workers given its share in the economy, potentially depressing agricultural labor productivity. It is therefore an important policy question whether to (1) continue supporting smallholders through custom-hired tractor services or (2) encourage smallholders to rent their farms out to medium-size or larger farmers, while helping smallholders specialize in the nonfarm sector, where their labor productivity may be higher. Using samples from the Terai zone—one of the agroecological belts in Nepal, largely consisting of lowland plains— from the Nepal Living Standards Survey, we assess whether the benefits of hiring in tractor services are greater among medium to large farmers than among smallholders, and how these benefits may depend on smallholders’ decision to remain in or leave farming. This study also contributes to the impact evaluation literature by showing that jointly assessing the effects of two treatments (whether to adopt custom-hired tractor services and continue farming, or to search for better options and specialize in off-farm activities) can lead to different implications than assessing them separately. Our analyses suggest that the government should continue to promote custom-hired tractor services not only for medium to large farmers but also for smallholders. If, over time, barriers to specializing in nonfarm activities are lowered and more smallholders start leaving farming, mechanization may no longer benefit the remaining smallholders. Support for mechanization can then be focused more on medium to large farmers, while types of support other than mechanization can be devised for the remaining smallholders.
