Abstract

This research was conducted to analyze the land use land cover changes (LULC) for the Hosaena town. For any LULC change analysis acquisition of multi temporal data is vital in order to detect the changes over the time. For this purpose satellite images (Landsat 2000, 2010 and 2018) have been used for retrieving information, adopting image classification method. In addition accuracy analysis has been done by comparing the reference data with the classification results to evaluate the effectiveness of the image classification . The changes between the defined years was evaluated using land use Land cover maps that belongs to different years adopting cross tabulation and overlay analysis methods., The result indicates that the main changes in the study area were the transformation of Agricultural lands and Grass land were converted into Built up lands in the study area. Accordingly, around 96.6 ha of area of Agricultural land were transformed to build up in the last two decades. The results of this specific study have shown that remote sensing and geographic information system were important tools to studies land use and land cover change. Therefore, based on the findings of this study, the following recommendations are recommended. The use of course imagery does not fit for high level of accuracy of urban features as they are complex and heterogonous. Hence, adopt high resolution imageries such as IKONOS and Quick Bird for generating quality land cover maps. Hence, the output of detailed maps is important to the planners, decision makers and stakeholders for efficient utilization of land.
