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.

Real-time market price monitoring: Current dynamics in southern Rwanda

Real-time market price monitoring: Current dynamics in southern Rwanda

Recent collaborative CGIAR research has developed a prototype for tracking district-level costs of a healthy diet using monthly eSoko data.1 High frequency monitoring of diets allows for near real-time generation of insights on price impacts on diet costs. The temporal richness of this data allows for immediate analytics of current food system events. This research provides an analysis of district-level price movements of healthy diet compositions, as well as food prices that compose the diet. We use this prototype to demonstrate how eSoko data could be used for monitoring an economic shock and how to evaluate the effects in near real time. The general goal is to demonstrate a potential early warning system that could improve the menu of policy choices for enhanced resilience.

Synopsis: Crop commercialization in Rwanda: Current market participation and drivers

Synopsis: Crop commercialization in Rwanda: Current market participation and drivers

As Rwanda emerges from the effects of COVID-19 and global price shocks caused by the Russia/Ukrainian conflict, there is an opportunity to focus on agricultural fundamentals to drive its economic transformation. One aspect of the transformation is how farm households are engaging in crop commercialization. This policy note outlines basic findings and suggested recommendations derived from a 2022 Rwandan commercialization household survey. Our basic unit of analysis is total crop sold divided by total value produced, averaged at either the household or individual crop level. Key findings include:  Approximately 20% of our sampled smallholder households do not sell any crops. However, contrary to a subsistence/commercial farm dichotomy, most households sell on a broad continuum ranging from 1 – 100% with an average of 33% of their total crop production marketed.  Crop value per hectare increases with greater marketed sales, indicating that farmers switch from lower value food crops (e.g. beans, cassava, maize) to cash crops such as fruits and vegetables where they market higher percentages.  Crop value per hectare is not correlated with land size, revealing that crop choices drive value and not increasing land-related economies of scale. This finding underscores the pivotal role of crop selection in determining agricultural productivity and economic returns, rather than mere expansion of land holdings.  Irrigation, land size, hiring labor and input purchases increase market participation as well as percentage of sales. Conversely, a larger family size has a negative effect on both.
