|Keywords:||GIS;Urban Change Detection.;Urban expansion;Remote Sensing|
|Abstract:||Urban environments are among the most dynamic systems on earth. Rapid urban expansion necessitates proper planning to avoid profound negative environmental and socioeconomic impacts. Geographic Information Systems (GIS) and Remote Sensing technologies provide very efficient tools to collect and analyse the information necessary to detect changes in urban areas that conventional surveying technology can't deliver in a timely and cost effective manner. GIS and Remote Sensing techniques were used in this work to locate and estimate the expansion of urban areas in Dukem town. Rapid urban expansion has caused not only social problems, but also environmental and socioeconomic problems in the town. The results show massive urban expansions during the study period. The population dynamics are the factors that make the population of certain area to change over time. In this case in 1986 the population of the town was 3736 and the built up area 43 hectare. The population was increased to 6356 in 2005 likewise the built up was expanded to 505.3 hectare. In 2010 the population became 25214 and the built up was expanded to 1095.44 hectare. From 1986-2005, the population of the town was increased by 2620 i.e. 70.13% and 2005-2010 it was 8858 i.e. 275.2%. The built up area of the town was increased by 462.3ha i.e. 1075% from 1986-2005 and it was expanded to 590.14ha i.e. 116.8% from 2005-2010.Population, nearness to Addis Ababa, and poor policy implementation are the major factors that derive horizontal expansion in the town.|
