Food supply chain resilience and the COVID‐19 pandemic: What have we learned?
Bibliographic record
Abstract
Abstract A year into the COVID‐19 pandemic, this paper reflects on the changes that occurred in agrifood supply chains in Canada and the United States. The sudden shift in food consumption patterns from food service to food retail required realignment of food supply chains. For the most part, food supply chains have performed remarkably well during the pandemic. Cross‐border food supply chains have continued to function effectively. The most significant disruptions emerged from workforce outbreaks of COVID‐19 in the meat processing sector and in fruit and vegetable production. The paper discusses supply chain resilience and argues that agrifood supply chains are characterized by several important differences that need to be taken into consideration when evaluating resilience. Economies of scale and scope offer economic efficiency advantages in normal times, while investments in adaptability and flexibility can enhance resilience for abnormal times. Potential long‐run changes within supply chains include increased automation and digitalization in food supply chains, while investments in infrastructure for online delivery services have permanently altered the food retailing landscape.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
