Deforestation is the replacement of forest by other land-use. Land-use patterns are changing fast in worldwide in relation to the human population growth and agricultural land expansion. The study deals with the status and trends of land-use and land-cover (LULC) dynamics and identification of deforestation risk zones Ankasha Guagusa, northwestern, Ethiopia following in the recent advancement in geospatial approach. The temporal Landsat satellite data from 1985 to 2018 was used for the analysis. Supervised classification approach with maximum likelihood algorithm was adopted for the classification and generation of land-use and land-cover maps for the chosen time periods. Results reveal that there have been substantial changes in the LULC during the selected periods. During the period 1985–1996 showed increased the cropland, bare-land and built-up with 835 ha (1.78%), 186.54 ha (0.4%) and 112. ha (0.24%), respectively. In the second period (1996–2006) forest land, built-up and cropland increased with 1094 ha (2.33%), 346.78 ha (0.74%) and 2185.7 ha (4.65%), respectively. This implies that the forest cover change had decreased by 1119.78 ha (2.38) in the first period and increased in the second and third period with 1094.04 ha (2.33%) and 772.91 ha (1.64%), respectively. It was raveled that forest cover though remained relatively stable around western part of the study area. Identification of deforestation risk zone to examine five factors criteria was selected such as infrastructure, topographic and socio-economic behavior of the area. These are slope, proximity to road, population density, proximity to river and proximity to town. Each criterion was evaluated with the aid of AHP and mapped by GIS. The degree of deforestation risk was categorized as extreme, high, moderate and low suitability areas, which represented 2%, 40.27%, 56.65% and 1.04%, of the study area, respectively. Therefore, sustainable forest management system is necessity to protect, conserve and rehabilitate the remaining forest.

砍伐森林是用其他土地用途代替森林。与人口增长和农业用地扩张相关的世界范围内，土地使用方式正在快速变化。在地理空间方法的最新进展之后，该研究研究了土地利用和土地覆盖（LULC）动态的现状和趋势，以及对森林砍伐风险区的识别（埃塞俄比亚西北部的Ankasha Guagusa）。分析使用了1985年至2018年的临时Landsat卫星数据。在选定的时间段内，采用带最大似然算法的监督分类方法对土地利用和土地覆盖图进行分类和生成。结果表明，在选定的时期内，LULC发生了重大变化。1985-1996年期间，耕地面积有所增加，分别为835公顷（1.78％），186.54公顷（0.4％）和112.公顷（0.24％）。在第二个时期（1996-2006年），林地，建成地和耕地分别增加了1094公顷（2.33％），346.78公顷（0.74％）和2185.7公顷（4.65％）。这意味着森林覆盖率变化在第一时期减少了1191.78公顷（2.38），而在第二和第三时期则增加了1094.04公顷（2.33％）和772.91公顷（1.64％）。令人惊讶的是，尽管研究区域西部地区的森林覆盖率保持相对稳定。选择了确定五个因素标准的毁林风险区，例如该地区的基础设施，地形和社会经济行为。这些是坡度，邻近道路，人口密度，邻近河流和邻近城镇。借助AHP对每个标准进行了评估，并通过GIS进行了映射。砍伐森林的风险程度分为极端，高，中和低适宜性区域，分别占研究区域的2％，40.27％，56.65％和1.04％。因此，可持续森林管理系统对于保护，养护和恢复剩余森林是必要的。
