in the Past Quarter Century in British Columbia: Implications for Food Security
Bibliographic record
Abstract
Abstract: This paper describes change in local food production in British Columbia with a focus on changes in the production of foods recommended for increased consumption by nutritionists. We determine, in one of the most productive agricultural provinces in Canada, whether secular trends in agricultural land use and food production, over the past quarter century, have resulted in increased production of foods recommended by nutritionists as more healthy and nutritious. In particular we are concerned with estimating the extent to which changes in agriculture and food production are congruent with official nutrition advice to avoid less healthy foods and to consume more vegetables, fruit, and whole grains. We demonstrate, using regularly collected agricultural census data, in spite of nutritionists’ advocacy for improved access to locally produced fruits, vegetables, and grains, since 1986, that BC agriculture is moving firmly in the opposite direction with greater production of animal fats, and hay and grain for animal feed and much reduced production of traditional fruits, vegetables, and grains designed mainly for human consumption. While nutritionists advise us to increase consumption especially of whole grains, vegetables and fruit, local production capacity of these foods in BC has decreased markedly between 1986

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.
