Abstract

 

The knowledge of land use land cover is important for many planning and management activities as it is considered an essential element for modeling and understanding the earth feature system. The land-use land-cover pattern of a region is an outcome of natural and socio-economic factors and their utilization by man in time and space. Land-use land-cover change has become a central component in current strategies in managing natural resources and monitoring environmental changes. Remote sensing and Geographical Information system (GIS) provide fundamental tools which can be useful in the investigation at the village district as well as the city levels. Remote sensing becomes useful because it provides synoptic view and multitemporal land uses/land cover data that are often required. The study area is prone to flooding and the most recent flood in the area occurred in 2003. This paper seeks to establish the current status of land use and land cover changes for Loko flood plain north eastern Nigeria as well as to determine the extent of these changes using Geographic Information System and remote sensing techniques. Two satellite images were acquired, one before and one after the flood disaster, the images acquired were classified. The classified pre-flood image and post flood image were subjected to change detection tool of the ArcGIS to asses’ changes in the land use land cover patterns were used to come up with a land use/land cover map classification for the flood plain. Image processing and image classification were done in order to establish the land use land cover of the area. Result of the output image from the change detection analysis conducted on the two Landsat images (1999 and 2005) show the degree of changes that occurred on the different land classes on the study area between the two periods covered in the study. The result revealed that shrub/grassland increased by 82.69ha, water body reduced by 8.27 ha, settlements reduced by 0.29ha, savannah woodland reduced by 42 ha while farm land increased by 3.93 ha. The study recommends that government should educate farmers on the need for proper environmental management for sustainable land utilization.
