Marchés institutionnels et soutien à l’agriculture familiale au Brésil : étude de cas de producteurs insérés dans le programme d’alimentation scolaire
Bibliographic record
Abstract
Au Brésil, les récentes avancées du Programme national d’alimentation scolaire (PNAE), qui articule soutien à l’agriculture familiale et sécurité alimentaire des populations précaires, vont dans le sens d’une relocalisation des circuits alimentaires. L’objectif de ce travail est de comprendre comment l’insertion d’un collectif de producteurs dans différentes formes de circuits courts, et notamment via ces politiques publiques de restauration collective, a permis de consolider un système agricole innovant, tant au point de vue productif, qu’en termes d’occupation du sol périurbain, d’entretien du paysage et des ressources naturelles, d’organisation du travail et de valorisation sociale de l’activité agricole, en mobilisant notamment la multifonctionnalité de l’agriculture comme outil d’analyse.

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.
