Abstract

fetched live from OpenAlex

Le projet d'Évaluation des pratiques de gestions bénéfique à l'échelle du basin versant (EBB) est financé par Agriculture Canada (AAAC). Cette étude met l'emphase sur la problématique de pollution diffuse agricole présente dans le sous-bassin versant du Bras d'Henri. Cette étude fait l'estimation de l'impact à la ferme d'une contrainte environnementale croissante et de la performance environnementale et économique des Pratiques de Gestions Bénéfiques (PGB) pour satisfaire une contrainte environnementale. Les objectifs du model était de maximiser les revenus nets agricoles en ce conformant à une contrainte environnemental, à l'utilisation unique des champs, et au respect des besoins nutritionnels des animaux. Les résultats indiquent que la présence d'une contrainte environnementale croissante : (1) réduit l'émission de pollution diffuse agricole, (2) force les habitudes de production à changer, (3) réduit les revenus nets agricole, et (4) fait en sorte que les coûts moyens d'abattement et les coûts marginaux d'abattement augmentent et accélèrent. De plus, soumis à des contraintes environnementales similaires, les fermes sont économiquement gagnantes lorsque la contrainte environnemental est fixée à l'échelle de du bassin versant contrairement à une contrainte environnementale fixée à l'échelle de la ferme.

Not 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.
