| Abstract | ||
| Land degradation is defined as a phenomenon or series of events that reduce the current and/or potential capability of soils. This research aims to monitoring the land degradation process for some soils located in Kafr El-Sheikh governorate from 2000 to 2020 years through assessing rate of the land degradation, contributing factors and degree using GIS techniques. Sentinel 2 image and digital elevation model (DEM) was used to extract physiographic map of the study area. The studied soils have a high risk of salinity, water logging, and compaction with account of 8.77, 40.67, and 31.25 % from the study area, respectively. Very high risk of sodicity is represent, 97.17% of the study area. The high Values of hazard are attributed to the excessive overflow irrigation practices, improper use of heavy machinery and the absence of conservation measurements. | ||
