Africa-Press<\/a> – Cameroun<\/a>. <\/strong><\/span>Publi\u00e9e le 21 avril 2021 dans la revue Nature, une \u00e9tude internationale coordonn\u00e9e par des chercheurs de l\u2019IRD et du Cirad, identifie pour la premi\u00e8re fois les massifs forestiers les plus vuln\u00e9rables \u00e0 l\u2019augmentation des pressions climatiques et humaines attendues dans les prochaines d\u00e9cennies.<\/p>\n

Cameroun, Gabon, R\u00e9publique du Congo, R\u00e9publique d\u00e9mocratique du Congo et R\u00e9publique centrafricaine.<\/p>\n

Cinq pays d\u2019Afrique centrale sur lesquels s\u2019\u00e9tend l\u2019un des plus grands r\u00e9servoirs de biodiversit\u00e9, le second massif de for\u00eat tropicale au monde.<\/p>\n

Une r\u00e9gion aux multiples for\u00eats distinctes, dont chacune r\u00e9agit diff\u00e9remment aux pressions climatiques et \u00e0 celles exerc\u00e9es par l\u2019homme, explique Maxime R\u00e9jou-M\u00e9chain, \u00e9cologue \u00e0 l’Institut de recherche pour le d\u00e9veloppement (IRD) et premier auteur de l\u2019\u00e9tude.<\/p>\n

Cette \u00e9tude met \u00e0 jour la premi\u00e8re cartographie transnationale des types forestiers de la r\u00e9gion. Un travail quantitatif impressionnant, accessible en ligne sur le site du Centre de coop\u00e9ration internationale en recherche agronomique pour le d\u00e9veloppement (Cirad).<\/p>\n

Il s\u2019appuie sur un \u00e9norme jeu de donn\u00e9es de pr\u00e8s de 6 millions d\u2019arbres. Pour se rendre compte de l\u2019ampleur des ressources utilis\u00e9es, \u00ab on estime que si une seule personne devait reproduire ce jeu de donn\u00e9es, il lui faudrait 1000 ann\u00e9es de travail de terrain \u00bb, pr\u00e9cise Maxime R\u00e9jou-M\u00e9chain.<\/p>\n

L\u2019objectif de cette recherche consiste \u00e0 combiner ces donn\u00e9es aux sc\u00e9narios climatiques et anthropiques futurs afin de comprendre quelles for\u00eats seraient les plus susceptibles d\u2019\u00eatre affect\u00e9es.<\/p>\n","protected":false},"excerpt":{"rendered":"
