Spatio-Temporal Assessment of Urban Expansion on Agricultural Landuse in Mubi Town Adamawa State, Nigeria

This research examined the potentials of GIS and remote sensing techniques in spatio-temporal assessment of urban expansion on agricultural land-use in Mubi town, from 1987 to 2010 so as to detect the change that has taken place in this status between these periods. Attempt was also made to project the subsequent change for the next 10 years 2020. In achieving this, the satellite imageries were classified (supervised classification) into various land uses, database for the land uses were created and change detection using statistical graph was introduced. GIS Software such as ArcView3.2a, ILWIS 3.1, ArcGIS, and Idrisi, were used for spatial analysis. Primary data was also analyzed using simple statistical analysis. The result of the work shows a rapid expansion in built-up area between 2000 and 2010, while the period between 1987 and 2000 witness gradual expansion. It was also observed that change by 2020 may likely follow the trend in 1987 and 2000. Suggestions were therefore made at the end of this work for further planning and decision making at both state and local government levels.
