This paper examines the use of GIS and Remote Sensing in monitoring settlement (built-up) growth in Ilorin between1972, and 2001
so as to detect the changes that has taken place in this class between these periods. Landsat data for three epochs were used in the
study. Supervised classification was carried out to identify five land use/cover types with particular emphasis on settlement.
Subsequently, an attempt was made at projecting the observed growth in the next 14 years. In achieving this, Land Consumption
Rate and Land Absorption Coefficient were introduced to aid in the quantitative assessment of the change. The result of the work
shows a rapid growth in built-up land between 1972 and 1986 while the periods between 1986 and 2001 witnessed a reduction in this
growth. It was also observed that change by 2015 may likely follow the trend in 1986/2001.An attempt was also made to suggest
possible ways to use the information contained therein optimally.
