GIS-Based Land Use and Land Cover Change Assessment around Assosa District, Upper Blue Nile Basin, Ethiopia
Main Article Content
Abstract
Early researchers have reported the high land use land cover change by using years 2009-2013. We try to detect the land use land cover change from the years 2013-2023 by taking three years 2013, 2018, and 2023 by using Landsat 8 images of each year. We have taken five land cover types. They are forest, farmland, built-up, barren land, and water body. From this land covers farmland and built up areas shows a dramatic increase in this three-year gap. Especially forests show a high decrement, the rest water body, and barren land show some change. We found that the decrement of forests from 2013 up to 2018 is -27% and also from 2018-2023 is -7% additionally the percentage change of increase of farmland between 2013-2018 is 19% and between 2018-2023 is 2%, built- up area increases by 4% between 2013-2018 also in between 2018-2023 it increased by 10%.this change indicates that it can cause a serious problem unless it cannot be resolved.
