The selection of sites and areas of study within the province of Nineveh, as the work routes were determined by dividing the province into several different directions for the purpose of covering the largest amount of land by covering the field, which can be reached according to the roads and land uses.

The data were then collected and recorded according to the objective to assess and determine the state of degradation and desertification and to identify the main processes and causes (such as vegetation degradation, overgrazing, water erosion and wind erosion) and recording and marking desertification (mild, moderate, severe, very severe) 15 samples were selected as selected areas for assessment purposes and some soil characteristics related to degradation were estimated.

Some routine analysis of the samples was carried out.

The conservation map was also drawn by ArcGIS9.3.

Five spatial data were merged with the mosaic to ensure full coverage of the boundary Wards off and then truncated map of the province of this data by the Global Program and Mapper12 find value Khodariya guide (NDVI) based on satellite data covering the province by ERDAS IMAGINE8.4 program.

The resulting vegetation guide maps classified in the same program, including dividing the map into several different regions.

The study concluded that three degrees of degradation identified according to the Dregne scale of desertification, which described in a comprehensive map of the province.
