Abstract

fetched live from OpenAlex

En Haïti, la couverture forestière est en constante régression et n’excède pas 3,5% du territoire national. Des aires protégées ont été créés pour préserver les rares massifs forestiers, dont l’Unité 2 du Parc National Naturel de la Forêt des Pins (PNN-FP2). Toutefois, les maigres ressources forestières de ce parc sont sujettes aux diverses pressions anthropiques, telles l’agriculture, l’exploitation du bois d’œuvre, l’urbanisation, etc. menant à la régression de leur superficie dans le paysage. Cette étude a évalué la dynamique spatio-temporelle de l’anthropisation des écosystèmes forestiers du PNN-FP2 à partir de quatre images Landsat datant de 1973, 1986, 1999 et 2018. L’approche cartographique combinée aux outils d’analyse de l’écologie du paysage a révélé que la couverture forestière naturelle a connu, en 45 ans (de 1973 à 2018), une dynamique régressive matérialisée par une perte de 59,63% de sa couverture au profit des classes anthropiques (Champs et jachères, Végétation dégradée et Sol nu). La régression de la couverture forestière est sous-tendue par la dissection et la fragmentation de ses taches par opposition à la création des taches de classes anthropiques. Nos résultats justifient le besoin urgent de développer une politique de gestion intégrée, adéquate et participative afin de préserver durablement les forêts du PNN-FP2.

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.
