Empreinte anthropique sur la dynamique des écosystèmes de la forêt classée d’Amou-Mono au Togo

In recent years, Togo's protected areas have been subject to a worrying process of anthropisation. This has led to a decline in forest ecosystems, their biodiversity and their functions. The general objective of this study is to assess the state of conservation of the classified forest of Amou-Mono between 1986 and 2021. More specifically, it aims to: (i) characterize the dynamics of land use from 1986, 2000, 2013 and 2021 and, (ii) assess the impact of changes in land use on the potential for carbon sequestration. A multi-date classification of Landsat images for the years 1986, 2000, 2013 and 2021 made it possible to quantify and assess changes in occupation. The dynamics of land use between 1986 and 2021 is mainly reflected by a regression of dense/riparian forests (81.40%) and open forests/wooded savannahs (67.79%) and the progression of wooded/shrubby Savannah (172.93%). Anthropogenic formations: Fields/fallow and Agglomerations/Bare soils, absent in 1986, occupy in 2021 respective proportions of 38.1 % and 2.19%. Human activities, particularly logging and agricultural clearing, are causing fragmentation and regression of forest ecosystems. Unless action is taken to reverse the trend, the conservation of biodiversity and ecosystem functions in this classified forest will be increasingly threatened.
