BackgroundSoil erosion in the Ethiopian highlands is considered to be one of the major problems threatening agricultural development and food security in the country. However, knowledge about the forces driving the long-term dynamics in land use is limited. Therefore, the aim of this paper was to analyse the spatial and temporal land use/land cover (LULC) changes and their environmental implications over the period 1964–2014 in the Gelana sub watershed, Northern highlands of Ethiopia. Two aerial photographs (1964, 1986) and a Landsat 8 image (2014) were the source of objective landscape data. The subjective supporting data was collected by group discussion, interview and field visits that include the collection of photographic evidence. Seven LULC types, namely forest, shrub land, cultivated and rural settlement, grass land, bare land, urban built up area, and wet land were identified.
