Desertification refers to land degradation phenomenon in arid, semi-arid and dry sub-humid areas, resulting from various factors including climate variation and human activities. For evaluation and mapping of desertification many research have been conducted leading to regional and local models. In this research, among different existing methods IMDPA‌ was selected and desertification intensity...

Investigation of desertification trend requires an understanding of phenomena that create changes singly or action and reaction together in an area that these changes were led to the desertification and land degradation. In the investigation of pedological criterion affecting on land degradation in Alluvial Fans, first, the map of units was created by overlaying and crossing maps of slope class...

About 80 percent of Iran is arid and semi-arid and about 35 percent of this area is susceptible to desertification hazard. Therefore desertification assessment and identification of the most important criteria for the assessment of risk and a basis for development of management plans is essential. This research was conducted in the semi-arid region of Agh-Band in the Golestan province, Iran wit...

Integrating remote sensing (RS) with geographic information system (GIS), distribution digital maps of land desertification, spatial database and their statistics in the year of 1986, 1993 and 2000 were obtained by correcting, amplifying and auto classifying the RS images of interlaced zone for agriculture and animal husbandry in northern Shaanxi. The results showed that in the last 15 years de...

the derakhte senged area is located in south of neishaboor town at khorasan razavi province. in this research, desertification intensity of derakht senged area was evaluated using imdpa, one of the newest method to assess desertification potential in arid and semi arid regions of iran. to evaluate desertification intensity, based on the primary research in this area, 4 criteria were selected in...

The farming and grazing interlocked transitional zone along the Great Wall in northern Shaanxi Province is particularly vulnerable to desertification due to its fragile ecosystem and intensive human activity. Studies reveal that desertification is both a natural and anthropogenic process. Four desertification indicators (vegetative cover, proportion of drifting sand area, desertification rate, ...
