Resume In Benin, sacred wood take on particular importance of ecological and socio economic second sight. But following the example of other natural formations, the sacred forests are degraded and their surface is reduced in a disturbing way because of human actions. The present research is particularly interested in the dynamics of the land use and its incidences on sacred wood in the north west of Atacora’ department. The CENATEL vegetation’s map 1990 and the satellite images of 13/01/1990, 31/01/2006 and 09/11/2014 obtained on the web site GLCF/USA were used. The data collection was made through the documentation, the download of images from internet and the map of vegetation. The data processing consisted at first time in the processing of landsat satellite images, then in meadow processing and in the extraction of the study sector and finally in the geometrical correction of the downloaded images. The results reveal that the surface of the sacred wood of the study sector is reduced between 1990, 2000 and 2014 periods because of the anthropological activities (rural works, vegetation, the town planning, the forestry development etc.). This degradation passed from 99,1 ha in 2000 to 91,03 ha in 2014 with e variations from less -0,14 % to less -1,87 %. This situation could be mastered if the pressures on sacred wood are reduced. In the opposite case, we shall observe the disappearance of most of sacred wood of the territory of research on the horizon 2050.
