Rwandan maize market price dynamics: Structure, trends and policy implications

The importance of maize for Rwanda cannot be overstated. Most smallholder farmers, along the spectrum of both land size and level of commercialization, engage in both production, own consumption, and sale of maize. Unlike most other crops, maize is commonly produced by all levels of commercialized and subsistence smallholder farmers. For example, recent research revealed that even though almost half of all maize produced is sold (44%), only an average of 23 percent is marketed at the household level (Warner et al. 2024). This indicates that while maize is widely sold by most smallholders, it is disproportionally sold by those with relatively larger farms. Therefore, maize is important for both own consumption as well as commercial sales and price movements are critical for understanding potential welfare impacts on both buyers and sellers. Research presented here outlines some important maize price relationships, including multi-year trends, interrelationships between Rwandan markets and seasonality. Overall, we find strong correlation between all markets suggesting a good degree of integration but persistent individual market prices above and below national averages as well as seasonality that generally conforms to maize’s main harvest period (Season A). This policy brief provides an overview of maize prices in Rwanda in order to enhance evidence-based policymaking for targeting recommendations aimed at more integrated and stable maize market prices throughout the country. For example, seasonal price changes suggest an annual average price fluctuation of approximately 30 percent and if targeted policies could reduce this seasonal price variation, smallholder welfare would likely be improved.

Synopsis: Enhancing smallholder farmers’ profitability through increased crop commercialization in Rwanda

Synopsis: Enhancing smallholder farmers’ profitability through increased crop commercialization in Rwanda

This study analyzes the costs, returns, and profitability of smallholder agriculture in Rwanda using a gross margin approach (definitions are provided below) and reveals that over 80 percent of farmers generate positive gross economic margins. However, only around 40 percent achieve positive gross marketing margins from crop sales. This difference is directly attributable to the fact that two-thirds of production is directly consumed by households. The analysis further identifies that farm households allocate about 80 percent of their total crop input expenditures to fertilizer, seed, and hired labor, while the remaining expenses associated with fixed production costs that are almost exclusively related to land rental costs. Furthermore, per hectare analysis reveals decreasing returns to scale for land size, disputing the notion that larger areas lead to efficiency gains. Instead, for example, smaller commercial farmers of less than 0.1 hectare, comprising 5.5 percent of our sample, sell over 50 percent of their crop value. Despite existing trends, this indicates that commercialization can take place on any size land holdings for relative income gains. Additionally, the study highlights the impact of factors like labor decisions and crop choice can significantly influence economic outcomes. The findings suggest that smallholder farming remains economically viable in Rwanda, though market participation is somewhat limited. With appropriate support and risk mitigation, farmers of all land sizes can commercialize production, boost incomes, and enhance household welfare by reorienting towards higher-value market crops.

Costs and returns in Rwandan smallholder agricultural production: Gross margins and profitability analyses

Costs and returns in Rwandan smallholder agricultural production: Gross margins and profitability analyses

This paper explores crop commercialization among smallholder agricultural households in Rwanda from a cost and revenue perspective to determine profitability at the farm level. We use standard revenue and cost equations to assess the commercial viability of the smallholders. In general, we find that a household’s total crop production creates positive returns even if implicit costs, such as own family labor and fertilizer subsidies, are included. Specifically, over 80 percent of our sample households generated positive economic returns from farming— referred to as demonstrating a positive gross economic margin (GEM). However, if only crop market sales and market input costs are used in the calculations, only 40 percent of agricultural households generated positive returns—referred to as demonstrating a positive gross marketing margin (GMM). Most of the explanation for this difference is that the typical farm household sells only about one-third of its crop production by value. This outcome suggests that many agricultural households continue to focus on cultivating food crops for their own consumption and do not specialize in commercial production. This is to be expected in an economic context where input, credit, and commodity markets are still developing, production decisions are still shaped by high levels of weather and market risk, and production risk management options are limited, among many other factors. The results of this research provide a better understanding of how Rwandan smallholders might move towards higher value production, with the ultimate goal being to increase household revenues and welfare and accelerate the country’s economic transformation.
