Circonscrire les gisements de biomasse-énergie pour protéger l'alimentation et la biodiversité : le défi intenable
Bibliographic record
Abstract
Par le transfert d'affectation des matières ou des sols, l'essor de la biomasse énergie engendre des concurrences avec les fonctions alimentaires et la biodiversité. On cherche donc à séparer les gisements, tirant les agrocarburants de seconde génération de la biomasse ligneuse, excluant le maïs des digesteurs de biogaz, réservant les cultures énergétiques aux terres marginales. Ces tentatives de séparation se heurtent à la perméabilité des réservoirs. Elle résulte des jeux sur les variations de temps réservées aux cultures alimentaires et énergétiques dans les parcelles, sur la durée des révolutions forestières qui, par les TTCR, connectent les sphères agricoles et forestières, sur les statuts des produits, sous-produits et coproduits sur les marchés, et du caractère trop approximatif de la notion de terres marginales.

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.
