Abstract
Cities and towns in developing countries all over the world are experiencing an unplanned and uncontrolled development known as Urban sprawl. Sprawl is often uncoordinated and extends along the fringes of metropolitan areas with incredible speed. This research is aimed at examining urban sprawl in Gombe metropolis between 1991 and 2014.The data used for the study were Landsat 5 Thematic Mapper (TM) of 1991, Landsat Enhanced Thematic Mapper plus (ETM+) data of 2005 and Enhanced Thematic Mapper plus (ETM+) of 2014.The extent of urban land use was determined by using the attribute and statistics data generated from the classification result and used for post-classification comparison among the years. The built-up was also extracted for each of the periods and the extent of the built up area was calculated in hectares.The extent of the urban sprawl was analyzed by subtracting the reference year of land cover of 2014 from the base year 1991. The resultsshow that urban land usewas high between 2005 to 2014 occupying about (51.43%) of the total land mass. The spatial extent of urban sprawl occupied about 12.78% between 1991 and 2014 andhigh annual rate of 12.78% were also witnessed in 2014.It was also found that there was a progressive increase of urban sprawl both in terms of extent and annual rate throughout the study period, especially between the period of 2005 and 2014. It is recommended that there is a need for a regular monitoringof urban sprawl and development in the study area by the state government especially with the aid of geospatial techniques for better decision making.
