During the decade of political and military crises of the 2000s in Ivory Coast, the classified forest of Haut-Sassandra (CFHS) located in the Central West has undergone many changes in its vegetation cover resulting in a significant change in its floristic composition and structure. The objective of this study is to determine after conflicts, the causative agents of these changes. To achieve this, a systematic sampling of damage types was done within the CFHS following 18 transects of 500 m each one. The agents responsible of these degradations were also identified. A total of 12 types of degradation have been identified of which four are most representative specifically slash and burn of stem base, association of food crops, falling trees and cocoa farms. The classification of geographic locations in decreasing degradation order revealed that the North and the East are the most altered by Human activities. With over 81.96% of presence on transects, cocoa farming is the main activity which causes the degradation of CFHS. With a percentage of 95%, Human is the mainly responsible of degradation observed in the CFHS. The crises arising conflicts have therefore promoted a significant human impact of CFHS. The lack of environmental monitoring during this period is one of the factors behind this strong anthropisation of CFHS.

Abstract: (french)
Au cours de la décennie de crises politico-militaires des années 2000 en Côte d’Ivoire, la forêt classée du Haut-Sassandra (FCHS) située au Centre-Ouest a subi de nombreux changements de sa couverture végétale entrainant une modification profonde de sa composition floristique et de sa structure. L’objectif de cette étude est de déterminer après les conflits, les agents responsables de ces changements. Pour y arriver, un échantillonnage systématique des types de dégradation a été effectué dans la FCHS suivant 18 transects de 500 m chacun. Les agents responsables de ces dégradations ont également été identifiés. Un total de 12 types de dégradation ont été déterminés parmi lesquels quatre types sont les plus représentatifs à savoir le brulis des pieds des arbres, les associations de cultures, les chutes d’arbres et les cacaoyères. La classification des sites géographiques par ordre décroissant de dégradation a révélé que le Nord et l’Est sont les plus modifiés par les activités humaines. Avec plus de 81,96 % de présence sur les transects, la cacaoculture est la principale activité qui entraine la dégradation de la FCHS. L’Homme est, avec un pourcentage de 95%, le principal responsable des dégradations observées dans la FCHS. Les crises nées des conflits ont donc favorisée une anthropisation importante de la FCHS. L’absence de surveillance environnementale pendant cette période est un des facteurs expliquant cette forte anthropisation de la FCHS.
