اثرات تغییر اقلیم بر پهنه‌های در معرض فرسایش بادی منطقه نیمروز سیستان

The purpose of this research is to monitor the condition of erosion zones in Nimroz region of Sistan during drought and normal years. To carry out this research, satellite images with high spatial and temporal resolution were prepared using Landsat and MODIS satellite images using exponential micro scale methods. Using the ESTARFM model, the images of drought and normal years were simulated. In order to monitor the changes of erosion zones by classifying the simulated images, the change detection operation was performed using the classification comparison method for these maps. The findings showed that during the period of drought to normal, the highest percentage of changes (35.84%) related to the conversion of barren lands into erosion zones with an area of about 32708.68 hectares and after that, the conversion of erosion zones into pasture lands with There was little vegetation.

In addition to that, the results show that with the arrival of water from Afghanistan to this region, with the increase in the level of flood zones, the extent of erosion zones decreases by 60% compared to the period of water scarcity. Therefore, the improvement of environmental conditions in the Sistan region requires demand of Iran's water rights from Afghanistan.
