USING REMOTE SENSING AND GIS TECHNIQUE IN MONITORINGEROSION IN MADA TOWN, ZAMFARA STATE

Abstract

 Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate and lead to significant impacts such as significant decrease in the productive capacity of the land and sedimentation. Mada town in Zamfara state experienced loss of farm lands due to erosion in the Mada stream area. This research study the quantification of soil erosion and measure the increment on the size of the stream for a twenty years period from year 2000 to 2020. Remote Sensing (RS) and Geographic Information Systems (GIS) techniques used for the assessment of the rate of erosion in the study area. Landsat satellite imageries for 2nd April, 2000, 7th April, 2010 and 25th May, 2020 are used to process, digitize and map the stream boundary with each image obtained.
