The study of the spatial evolution of forest galleries in the humid savannah of Adamaoua-Cameroun was conducted between 2013 and 2017 in all five departments of the region and aimed to see the dynamic evolution of the gallery surfaces. In comparison with other types of land use (savannah, shrubby savannah, habitation, etc.). For this, a socioeconomic survey was conducted to have the perception of local residents on the evolution of plant density. A diachronic study with acquisition of satellite images was conducted. The socio-economic survey showed that 50.71% of respondents believe that there has been an increase in the density of ligneous trees in the last ten years. However, opinions are divided between the five departments of the Adamaoua region. Satellite images have shown that the forest galleries of Adamaoua are the most attacked ecosystems compared to savannah and shrub savannah. Between 1986 and 2006, the forest galleries lost 8.94% of their area, an area of 5694.86 km2. Between 2006 and 2016, the Adamaoua forest galleries lost once again 3.75% of their area, or 2376Km2. The forecast has shown that by 2037, the forest galleries of the region will lose 4752.08 km2 of their area if nothing is done. This degradation led to a considerable reduction in the surface area of 101.92 km2 of large waters between 1986 and 2006. However, the increase in the savannah area of an additional 407 km2 (2006 to 2016) would have made it possible to increase the surface area 184.73 km2.
