Abstract
Rapid urban development and increasing landuse changes due to increasing
population and economic growth is being witnessed of in Ethiopia and other
developing countries. The measurement and monitoring of these land use
changes are crucial to understand land use cover dynamics over different spatial
and temporal time scales for effective land management. Urban sprawl may be
defined as the scattering of new development on isolated tracts, separated from
other areas by vacant land (Ottensmann, 1977). Geographic Information System
and Remote Sensing data were used to analyze the pattern of urbanization. This
was done using temporal satellite image of the study area in year 1986 and 1999
and demographic details from central statistics agency of FDRE. This enabled in
quantifying the increase in the built-up area for nearly 14 years. The built up also
helps to identify the Shannon¡fls entr opy,which is a measure of concentration of
dispersion. With intent of identifying the causal factors, this could be modeled and
projected for the future decades. This study is aimed at helping scientists, policy
makers, engineers, urban planners and ultimately the common man to visualize
how towns and cities grow over a period of time based on investigations in the
regions around the highway and cities
