Abstract: The land use changes were detected using Remote sensing and GIS and this was very important in detecting the nature, rate and location of changes. Change detection of the study area was carried out for the years, 1994, 1999, 2000, 2004, 2005, 2009, 2010, 2014 and 2019. A land use classification scheme was developed for the area, There was a major decline in most of the land use in the study area. This was noted to majorily caused by mans activities. Water bodies also experienced a change within the periods worked on. Between 1994 and 1999 the water body area covered was 13576 m but decreased to 11784 m between 2000 and 2004, despite this fact the study area experienced a lot of flooding in few years past and this was deduced to be caused by illegal dredging activities and sand filling of river paths. Farm lands, built up areas all changed in dimension in different years and all these were attributed to mans activities. Land use change detection was able to help in determining and comparing the percentage changes as well of rate a of change and this could help in decision making.
