An Impacts of Urban expansion on the Livelihood of Farming Community in Peri-Urban Areas of Dessie Town Using GIS and Remote Sensing Techniques

The high rate of urbanization coupled with population growth and migration has caused changes in land use and land cover in Ethiopia. Therefore, understanding and quantifying the spatio- temporal dynamics of urban land use and land cover changes and its driving factors requires lu/lc map integrated with socio economic data. Therefore, the objective of this study was to assess the impact of urban sprawl on farming Communities over the last 30 years of Dessie town. This study used Remote Sensing and Geographic Information system for quantifying urban land use and land cover change dynamics. Socio economic data was used to analyze the impacts and factors of urban sprawl on prei urban farming communities. Three dates of Landsat image data of the 1988, 2006 and 2018 were used to produce land cover map in general and urban expansion map in particular .Digitization, image differencing and post-classification comparison change detection methods were employed. In addition to this, socioeconomic data were used in explaining the drivers of urban expansion in the study area. The results showed that during the last 30 years, built up area increased from 1088.19ha in 1988 to 3826.5hain 2003 and 6091.12 ha in the year 2018. The annual rate of built up area cover change between 1988 and 2003 was 182.52ha/year. The socioeconomic factors like population growth, rural-urban migration, and reclassification of land is the major driving forces for the observed built up area increment. Therefore, in order to reduce the problem national and regional government policies in terms of urban expansion and other responsible body should get considerable attention for urban planning to reduce the rate of those factors. Like that of improving vertical expansion rather than horizontal
