Orisakwe K. U.

Abstract
This study has to do with the determination and analysis of Landuse/Landcover (LULC) dynamics within the period of 31 years viz: 1978 – 2009. Three multidate datasets comprising a basemap of 1978, satellite images of 2005 and 2009 using the combined technologies of Remote Sensing (RS) and Geographic Information System (GIS) to determine the magnitude, rate and dynamics of change in landuse within the study period of the area. The analogue basemap of the area of study was cropped, concatenated, georeferenced, digitized, polygonized and post-classified. The satellite images, submaps created were georeferenced and classified by the method of unsupervised classification based on the following classification scheme: Residential, Commercial Water Bodies, Vegetation, Public Areas and Industrial Areas. Post-Classification approach was adopted which involved the analysis of differences between two or more independent categorization products. The result showed significant rapid growth in Residential Landuse while the vegetation is diminished annually. The annual rate of change in landuse was determined and used as an index in predicting changes for the future using simple regression statistics. Adequate recommendations were made for the town planners, administrators and policy makers for Landuse development in Hadejia Township.
