摘要

Urbanization and population growth are the major drivers of land use and cover changes in peri-urban areas. This study aimed to analyze urban expansion and land use and land cover (LULC) changes in Wolaita Sodo City, South Ethiopia. Three Landsat (2003, 2013, and 2023) satellite images were used for the study over 20 years. GIS and remote sensing techniques were used to analyze urban expansion and land cover changes in the city. The maximum likelihood algorithm for supervised classification was used to create LULC maps. The satellite image results show that built-up areas increased by 4,654 ha (10.82%), 7914.9 ha (18.4%), and 11681.5 ha (27.2%), respectively, in the first, second, and entire study periods, though the rate was 326.09 ha/year, 376.66 ha/year, and 702.75 ha/year in the first, second, and entire study periods. This rapid growth due to city development has resulted in land grabbing, mainly affecting peri-urban farmers. Managing urban expansion, land use, and agricultural land invasion are crucial for livelihoods. Future studies should integrate innovative techniques with land-use optimization to identify areas that will be covered by future city growth. This will help to balance urban development and environmental conservation.
