TY - JOUR ID - TI - USING OF REMOTE SENSING AND GIS TECHNIQUES TO ASSESS THE DESERTIFICATION AND ITS EFFECT ON AGRICULTURAL LANDUSE: AL-GARMA (STATUS STUDY) استخدام تقنيات الاستشعار عن بعد ونظم المعلومات الجغرافية في تقييمحالت التصحر واثارها على الاستعمالات الارض الزراعية ناحية الكرمة (دراسة حالة) AU - Izzadden G. Darwesh عز الدين جمعة درويش PY - 2013 VL - 5 IS - 1 SP - 175 EP - 181 JO - IRAQI JOURNAL OF DESERT STUDIES المجلة العراقية لدراسات الصحراء SN - 19947801 26649454 AB - This study was conducted to determine the manifestations of desertification in Al-Anbar province (Algarmadistrict), depending on the technology of remote sensing using GIS software scanning an area of 473,200 acres,and I have used two satellite images one of them in 1990 and the other one in 2010. The results showed thatthere has been a change in the area of the calculated manifestations of desertification from the two satelliteimages by a visual interpretation method through insulating the map units by Arc program GIS 9.3 with thecomparison between their areas. There was an increase in sand dunes which it reached to (54 640 and 94 720)acres in 1990 and 2010 on sequence. And the areas of salt affected soils were increased to which reached to(87,480 and 111,960) acres for the two satellite images of 1990 and 2010. The area of cultivated land and arableland in the study field reaching (74 720 and 67600) acres in 1990 and 2010 for the cultivated land and as for thearable land reached to (70640and 68360) acres, for the reasons mentioned in the manifestation of desertification.
