Land use/land cover change analysis using geospatial techniques: a case of Geba watershed, western Ethiopia

Abstract Land use/land cover change is a global environmental problem that significantly affects sustainable development and quality. Anthropogenic activities are one of the main driving forces land in developing countries like Ethiopia. This study conducted Geba watershed southwestern parts aimed to analyze over past thirty years using geospatial technologies. The present uses Landsat TM 1990, ETM + 2003, OLI/TIRS 2020 examine between 1990 2020. classes classified supervised classification method with maximum likelihood technique. Results show agricultural increased significantly, from 1786.6 km 2 (37.2%) 3163.2 (65.8%) 2020, representing an rate 45.9 /year. On other hand, dense forest has declined 2129.2 (44.3%) 1127.8 (23.5%) which declines by 33.4 Our findings suggest use planning management critically important area.
