Fertilizer demand and profitability amid global fuel-food-fertilizer crisis: Evidence from Ethiopia

Fertilizer demand and profitability amid global fuel-food-fertilizer crisis: Evidence from Ethiopia

We assess fertilizer demand and profitability in Ethiopia in the face of the recent global fuel–food–fertilizer price crisis and other domestic shocks. We first examine farmers’ response to changes in both fertilizer and food prices by estimating price elasticity of demand. We then evaluate the profitability of fertilizer by computing average value–cost ratios (AVCRs) associated with fertilizer application before and after these crises. We use detailed longitudinal household survey data collected in three rounds, covering both pre-crisis (2016 and 2019) and post-crisis (2023) production periods, focusing on three main staple crops in Ethiopia (maize, teff, and wheat). Our analysis shows that fertilizer adoption, and yield levels were increasing until the recent crises, but these trends have been halted by these crises. We also find slightly larger fertilizer price elasticity of demand estimates than previous estimates, ranging between −0.40 and −1.12, which vary across crops. We find that farmers are more responsive to fertilizer prices than to output prices. Farmers’ response to increases in staple prices was statistically insignificant and hence not as strong as theoretically perceived. Households with smaller farm sizes are relatively more responsive to changes in fertilizer prices. Finally, we show important dynamics in the profitability of chemical fertilizer. While the AVCRs show profitable trends for most crops, the share of farmers with profitable AVCRs declined following the fertilizer price surges. Our findings offer important insights for policy focusing on mitigating the adverse effects of fertilizer price shocks.

Seeds of change: The impact of Ethiopia’s direct seed marketing approach on smallholders’ seed purchases and productivity

Several factors contribute to the limited use of improved seed varieties in Ethiopia. Among those, on the supply side, is the restricted availability of seeds in the volume, quality, and timeliness required by farmers, partly due to inadequate public and private investment in the sector. Beginning in 2011, the Government of Ethiopia introduced a novel experiment—the direct seed marketing approach—to reduce some of the centralized, state-run attributes of the country’s seed market and rationalize the use of public resources. Direct seed marketing was designed to incentivize private and public seed producers to sell directly to farmers rather than through the state apparatus. This study is the first quantitative evaluation of the impact of direct seed marketing on indicators of a healthy seed system: access to quality seeds and farm-level productivity. Using a quasi-experimental difference-in-differences approach suitable to handling variation in treatment timing, the study finds that direct seed marketing led to an increase of 15 percentage points in the proportion of farmers purchasing maize seed, an increase of 45 percent in the quantity of maize seed purchased per hectare, and an increase of 18 percent in maize yield. However, there are differences across crops, with the effects of direct seed marketing on wheat seed purchases and yields being statistically insignificant. These crop-specific differences in performance are likely explained by differences in the reproductive biology of maize (particularly maize hybrids) and wheat, which tend to incentivize commercial activity in hybrid maize seed markets more than in self-pollinating wheat or open-pollinated maize markets. These differences suggest a need for nuanced policy responses, institutional arrangements, and market development strategies to accelerate the adoption of improved varieties.

Production and consumption traits and the adoption of improved maize varieties: Evidence from seed sample packs and cooking demonstrations

Production and consumption traits and the adoption of improved maize varieties: Evidence from seed sample packs and cooking demonstrations

In developing countries, semi-subsistence farmers typically assume dual roles as both consumers and producers of the same crops, which shape their adoption decisions as they balance household food security with market-driven incentives. This study, conducted in eastern Uganda, employs a field experiment with two intervention arms to assess the relative importance of these factors in farmers’ decisions to adopt improved maize seed varieties. The first intervention focuses on production traits, distributing free sample packs of an improved hybrid maize variety to showcase benefits such as higher yields, pest resistance, and drought tolerance. The second intervention emphasizes consumption traits, offering cooking demonstrations and blind taste tests using flour from the same improved maize variety to highlight its taste, texture, and ease of preparation. Our findings reveal that while seed sample packs positively influenced farmers’ perceptions of both production and consumption traits, cooking demonstrations primarily affected perceptions of consumption qualities. We find some evidence that the cooking demonstrations and tasting sessions significantly boosted adoption of the improved maize seed variety promoted by the intervention. However, farmers who received seed sample packs tended to recycle the harvested grain as seed in subsequent seasons, thereby crowding out fresh seed purchases. This practice led to productivity losses, suggesting that the seed trial packs did not translate into lasting improvements in food security or increased market participation.
