Abstract

The study area is located in the lower part of the Euphrates basin at the modern plain of Mesopotamian at 169 path and 37 row landsat7, the area was 8051.94 hectare. Land degradation was studied using Land Degradation Index (LDI), to determine some of the quantitate parameters of land degradation degree as relative extent, degradation rate, severity of degradation level. in the study area. The Relative yield of some major crops (tractum, bare, zea, and cotton) was assessed using the relative yield equation. The Results showed that there is a continuous increase in the areas of lands with severe and very severe degradation with value of (10.21hactar/year,16.5hectar/year). with a mild increase in the area of land of slight degradation with value of (3.43h/y with ratio of 0.04% year with a significant with decrease in lands with moderate degradation by 30.17 hectare/year with ratio 0.37%. which shows the seriousness of the degradation danger in the study area due to the continuous transformation of lands to sever and very sever degradation areas. Area with 72.42% of total area is very low Relative yield for maize planting and 46.46 % of total area is very low relative yield for wheat and with 43.30% of total area is very low Relative yield for barley and cotton planting.
