ABSTRACT

This project examines the use of GIS and Remote Sensing in mapping Land Use Land Cover in Ilorin between 1972 and 2001 so as to detect the changes that has taken place in this status between these periods. Subsequently, an attempt was made at projecting the observed land use land cover 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 class. It was also observed that change by 2015 may likely follow the trend in 1986/2001.

Suggestions were therefore made at the end of the work on ways to use the information as contained therein optimally.
