Evaluating Erosion using Remote Sensing and GIS Technique A Case Study of Mada Town, Zamafara State

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 has experienced loss of farm lands due to erosion in the mada stream area. This research studies the quantification of soil erosion by measuring 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 have been implemented 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 were processed and digitized to map the stream boundary for each image to obtain the area enclosed by each. The results shows that from 2000 to 2010 and 2010 to 2020 there is an increase in size by 31849.8497 m² and 33767.7233 m² respectively. It also shows that area eroded from 2000 to 2020 is 65617.5730 m² which is the farm land area lost by erosion in the study area which if not addressed may lead to more farm lands in the future. The research ends by recommending policies such as providing vegetation cover which will reduce the impact of erosion in the study area. M. S. Lugga | Emakoji M.
