Abstract
The study explores the where and what land use type has changed in the city of Hawassa within 20 years. The changes were used to explore the dynamics and drivers of land use/land cover change and the effect on household livelihoods. To investigate the change detection, the Landsat satellite images of 1995, 2000, 2003, 2010, 2013 and 2014 were downloaded from U.S. Geological Survey archive under the path/row extent of 168/55. Thereby, buildings, water, vegetation and agricultural lands were classified using screen digitization on ArcGIS. Based on trends of expansion agricultural lands and vegetation covers have been decreasing at the rate of 44.48% & 27.16% respectively from the years 1995 to 2014. While built-up areas were rapidly increasing at the rate of 195%. The direction and expansion of these changes were also visualized. The focusing point was investigating the infrastructure services, the expansion of city in Perry-urban areas in terms of time series analysis. Besides, the Household livelihoods and infrastructure services were investigated grounded on the standards of sustainability. Under the finding, the rapid population pressure is the major cause for the increasing demand of built-up lands that creates pressure on services and household livelihoods. These resulted people to engage on hand-to-mouth economic activities such as street vending, shopping, daily laborers, metal works, petty-business and wood works. Overall, the city is rapidly increased through the expense of Peri-agricultural lands. Households in the Peri-urban areas are also marginalized and affected by shortage of infrastructure services.
