Abstract
Find draws to monitor the degradation of natural vegetation to assess the condition of pastures through the use of modern technologies such as remote sensing and geographic information system. The study identified the vegetation in some districts of Al- Anbar (Al-kaim, Ana, Hadetha) to assess the state of pastures, using Normalized Difference Vegetation Index NDVII. The study identified the area of the digital image satellite has been processing and analysis of data for Normalized Difference Vegetation Index NDVI. Adopted the study area as a model for the rest of the districts based on satellite images of the area available and LANDSAT captured in 2002 and in 2012 through the work of the calculated and comparisons between the two study periods of ten years to calculate the density of vegetation. Areas were calculated for class 2:0.1-03 (herbs and grasses) and extracted donum amounted to 18286 donnem in 2002, while reaching to 24142 donnem for 2012. Calculated based on the proportion of greenness area of the study area and the amount of 9746400 donnem has reached 0.18% of the area of the region in 2002, while 0.24% recorded for 2012. The results indicate an increase in NDVI Index which estimated at 0.06% in 2012 compared to that of 2002 and considered this a very slight increase. This explains that despite efforts to improve the condition of pastures, but it is still below the required level. This is due to the long period of severe drought and a long period of repeated exposure in the country in general and the study area in particular, and not to follow the style of sustainable natural resources. Tilling and dangerous process of random non-scientific process led to the uprooting of shrubs from the root. Were given the most important recommendations that can be tapped if properly applied to achieve sustainable management of rangelands.
