Does labelling differentiate products and create price premiums? The case of tomatoes from northeast Nigeria

This note describes a labelling experiment introduced to crates of tomatoes cool transported from the northeast region of Nigeria to Lagos or Port Harcourt. A label was attached to a random sample of crates to ensure that the quality of tomatoes is orthogonal to the labels and the destination market was not informed of the experiment. The label contained the information on (a) the project (IFPRI), (b) the transportation method (cool transportation), and (c) the origin of tomatoes (Jos or Gombe), as shown below. The experiment was conducted in the first rounds from Jos and Gombe (Lagos), and the fifth round from Jos (Port Harcourt). As expected, the labeled crates were priced higher than the unlabeled crates. About 9 to 33% of the sale price is attributed to improved information on the quality of tomatoes via the labels.

Solar drying technology for post-harvest loss management of horticulture products: Findings from baseline survey in Nigeria

Solar drying technology for post-harvest loss management of horticulture products: Findings from baseline survey in Nigeria

Creating a sustainable food system requires addressing the critical challenges of food waste and loss. This is particularly crucial for small-scale farmers who supply local markets but lack access to modern preservation technologies, leading to significant product losses between harvesting and selling. Research indicates that in low-and middle-income countries, approximately 38 percent of harvested perishable agricultural goods are lost before consumption. Globally, about 22 percent of fruits and vegetables are lost in the supply chain before reaching retailers (FAO, 2019). These postharvest losses have significant impacts to low economic return and household food and nutrition security. Post-harvest losses also contribute significantly to environmental concerns, accounting for roughly 8 percent of yearly global greenhouse gas emissions. Among all food categories, fruits and vegetables experience the highest losses by weight.

Impacts of cool transportation in Nigeria: Midpoint analysis

Impacts of cool transportation in Nigeria: Midpoint analysis

A randomized controlled trial was introduced to see impacts of cool transportation that connects three vegetable markets in northeast and two large demand centers in southern regions of Nigeria. This note summarizes the findings from the midpoint analysis. First, the impact of cool transportation is large and statistically significant. Sales price, revenue and profit significantly increase for marketers. Second, impacts on sales price are quantitatively large, and a larger portion of sales price increase is attributed to refrigeration, that is, quality preservation through cooling. About 70% of the increase comes from cooling; only 30% from transportation. Third, impacts on revenue and profit, relative to non-cool transportation, are also quantitatively large. In particular, the analysis shows a large proportional increase in profit.
