Abstract

fetched live from OpenAlex

Food loss and waste is an issue in Canada. The over production of agricultural products can lead to declining land fertility, deteriorating sustainable environment, and wastage of energy. In comparison with other categories of agricultural products, the loss rate of fruit and vegetables is much higher because they cannot be stored for a long time and easily. Like other developed countries, most food is lost in Canada at the retailing and consuming level, which researchers tend to pay more attention to than other stages of the supply chain. In developing countries, food loss and waste occur primarily at the post-harvest stage, where the local food system is dominant. Recent studies suggest that on-farm food loss could be more severe than estimated before. Producers in some studies suggested that high cosmetic standards set by retailers and distributors lead to higher on-farm food loss rates than local marketing channels. Therefore, it is necessary to understand if it is true that producers selling through local marketing systems have lower food loss rates than producers selling through other marketing channels. We conducted a survey of fruit and vegetable producers in Québec and Ontario about their food loss rates at farmgate, the composition of marketing channels, and other factors that potentially impact the on-farm food loss rate. We found out that, compared to local channels, selling more directly to retailers statistically significantly reduces the on-farm food loss rate, but the absolute value is quite small. Small-scale farms have lower on-farm food loss rates than larger farms. Processing on farm also significantly reduces food loss on the farm. This study suggests that local marketing channels may not necessarily mean a lower on-farm food loss rate and that selling more directly to retailers could reduce on-farm food loss. However, producers need to consider their own situation to take measures to reduce on-farm food loss without compromising their income and welfare

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
