      abstract = {In Cameroon, the pressure on wetlands, which cover nearly  70% of the national territory, appears to be increasing,  whether for subsistence needs, firewood, grazing, logging  or expansion of development projects. Currently, in terms  of land use, forest has decreased by 619 km² and cultivated  land has increased by 321 km². The surface area of degraded  forests and land is estimated at around 12 million  hectares, with a general trend towards an increase in the  phenomenon due to both natural and anthropogenic factors.  It is obvious that approaches in favour of wetlands are  widely engaged in the different basins of Cameroon.  However, the management strategies for these areas are  based on knowledge that is certainly extensive, but still  patchy. There is a serious lack of overview of the location  of degraded lands, the intensity of this degradation and  the way farmers are addressing this problem through  sustainable land management. The objective of this study is  to characterize the dynamics of land cover from multi-date  satellite data in the Noun floodplain of Cameroon. The  methodology relies on the use of remote sensing and GIS to  identify spatial units and detect changes over a twenty-two  year period (1999 to 2021). The land cover maps were  produced from an unsupervised classification with maximum  likelihood. The results identified eight classes:  herbaceous savannahs with shrubs, forest galleries, fields  and plantations, herbaceous tannas, young fallows,  mineralized and built-up soils, bare soils and surface  waters. It appears that in 1999, the landscape was  dominated by natural vegetation (72.6%) located from north  to south of the Noun plain. However, since 2004, the  landscape has been dominated by agricultural areas (56.8%).  Natural formations have been progressively reduced in space  over time. The evolution of the Noun floodplain landscape  reveals that 14.3% of the space has remained stable. These  are fields and plantations, young fallows, mineralized  soils and surface water. This space has not migrated to  other classes. While about 73.9% of the area has moved to  higher classes, of which 35.6% to herbaceous tannas and 26%  to fields and plantations. On the other hand, 72.6% of the  area (herbaceous savannahs and forests gallery) has been  heavily degraded. These results indicate that the landscape  of the Noun floodplain is marked by a high level of  agricultural activity, which is at the origin of the  progressive degradation of the land.  They suggest an  effective awareness of the level of land degradation and a  better integrated management of land at the local level.},
