La carte SBTN Natural Lands Map v1 est une carte de référence de 2020 des couvertures terrestres naturelles et non naturelles. Elle est destinée aux entreprises qui définissent des objectifs scientifiques pour la nature, en particulier l'objectif SBTN Land 1 : aucune conversion des écosystèmes naturels.
Les définitions de "naturel" et "non naturel" ont été adaptées à partir de la définition d'un écosystème naturel de l'initiative Accountability Framework, qui est "un écosystème qui ressemble sensiblement, en termes de composition des espèces, de structure et de fonction écologique, à ce qui se trouverait dans une zone donnée en l'absence d'impacts humains majeurs". Il peut également inclure des écosystèmes gérés ainsi que des écosystèmes dégradés qui devraient se régénérer naturellement ou par le biais d'une gestion (AFi 2024). La carte des terres naturelles de SBTN opérationnalise cette définition en utilisant des proxys basés sur les données disponibles qui s'alignent sur les conseils de l'AFi dans la mesure du possible.
Cette carte a été créée en compilant des données mondiales et régionales existantes.Vous trouverez la note technique complète expliquant la méthodologie sur GitHub Natural Lands.
Ce travail est le fruit d'une collaboration entre le Land & Carbon Lab du World Resources Institute, le World Wildlife Fund US, Systemiq et SBTN.
