Quelle accessibilité aux ressources pastorales du Sahel ?
Bibliographic record
Abstract
Les évolutions du couvert végétal sahélien diffèrent entre la résilience sur les sols sableux et la dégradation sur les glacis rocheux, dans un contexte d’expansion des superficies cultivées. Les ressources fourragères ne déclinent pas tant en production qu’en qualité et sont moins accessibles au bétail. Malgré l’ampleur des pertes au cours des sécheresses, les effectifs du cheptel progressent et contribuent à renforcer la charge animale sur les parcours. Son impact sur l’agro-écosystème reste modéré tant que l’élevage est pastoral et mobile. En revanche, les performances reproductrices des troupeaux sont affectées par la perte de mobilité non compensée par des intrants alimentaires. L’élevage pastoral naisseur, qui ravitaille les élevages d’opportunité en jeunes animaux, doit maintenir et sécuriser la mobilité du bétail, qui lui permet d’optimiser l’offre fourragère, en réduisant les effets dommageables de la pâture.

How this classification was reachedexpand
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.
