dc.description.abstractTechnologies like geographic information system (GIS) and Remote Sensing (RS) are used to monitor urbanization, map it, and monitor environmental changes. Since Dejen town is expanding improperly due to growth of population and improper settlers from remote/rural areas to the city, planned development and up-to-date information is needed on the Land Use and Land Cover (LULC) and population of the town to improve the problems. The project's overall goal was to use GIS and remote sensing methods to study LULC classification and analyze trends in Dejen town between 1993 and 2023. The literature review mainly focused on the concepts and definitions of GIS, Remote Sensing, LULC, LULC Mapping, LULC Change detections, and causes for urban expansion in the study area. The Landsat imagery data were used for the research study. Those data were processed using ArcGIS 10.7, and ERDAS (Earth Resource Data Analysis System) software. Accordingly, the satellite images were used to monitor LULC changes from the years 1993-2023 for the five identified LULC classes. The Landsat images were classed into built-up and non-built-up areas to concentrate on urbanization after five distinct kinds of land use and land cover classes were found using supervised classification. The finding of the study showed that, the built up area has increased from 177ha in 1993 to 958ha in 2023, forest area increased from 0.45ha to 107ha, barren land decreased from 334ha to 162ha, agricultural land decreased from 1613ha to 868ha and a slight change occurred in open area decreased from 269ha to 298ha. Built up area has exhibited the most noticeable changes (7.39% to 40.03%) from 1993 to 2023, which come from agricultural land and barren land. The result of the study showed that the most fertile and productive part of the agricultural land has changed to urban land. The study results provide valuable information for the city administration for planning unmanaged urban growth. It also provides useful knowledge for policy relevant land administration for future development related to land use plan associated to urban expansion.
